The framing layer of HTTP/2 is implemented as a reusable C library. On top of that, we have implemented an HTTP/2 client, server and proxy. We have also developed load test and benchmarking tools for HTTP/2. An HPACK encoder and decoder are available as a public API. Development Status ------------------ nghttp2 was originally developed based on `RFC 7540 `_ HTTP/2 and `RFC 7541 `_ HPACK - Header Compression for HTTP/2. Now we are updating our code to implement `RFC 9113 `_. The nghttp2 code base was forked from the spdylay (https://github.com/tatsuhiro-t/spdylay) project. Public Test Server ------------------ The following endpoints are available to try out our nghttp2 implementation. * https://nghttp2.org/ (TLS + ALPN and HTTP/3) This endpoint supports ``h2`` and ``http/1.1`` via ALPN and requires TLSv1.2 for HTTP/2 connection. It also supports HTTP/3. * http://nghttp2.org/ (HTTP Upgrade and HTTP/2 Direct) ``h2c`` and ``http/1.1``. Requirements ------------ The following package is required to build the libnghttp2 library: * pkg-config >= 0.20 To build the documentation, you need to install: * sphinx (http://sphinx-doc.org/) If you need libnghttp2 (C library) only, then the above packages are all you need. Use ``--enable-lib-only`` to ensure that only libnghttp2 is built. This avoids potential build error related to building bundled applications. To build and run the application programs (``nghttp``, ``nghttpd``, ``nghttpx`` and ``h2load``) in the ``src`` directory, the following packages are required: * OpenSSL >= 1.1.1; or wolfSSL >= 5.7.0; or LibreSSL >= 3.8.1; or aws-lc >= 1.19.0; or BoringSSL * libev >= 4.11 * zlib >= 1.2.3 * libc-ares >= 1.7.5 To enable ``-a`` option (getting linked assets from the downloaded resource) in ``nghttp``, the following package is required: * libxml2 >= 2.6.26 To enable systemd support in nghttpx, the following package is required: * libsystemd-dev >= 209 The HPACK tools require the following package: * jansson >= 2.5 To build sources under the examples directory, libevent is required: * libevent-openssl >= 2.0.8 To mitigate heap fragmentation in long running server programs (``nghttpd`` and ``nghttpx``), jemalloc is recommended: * jemalloc .. note:: Alpine Linux currently does not support malloc replacement due to musl limitations. See details in issue `#762 `_. For BoringSSL or aws-lc build, to enable :rfc:`8879` TLS Certificate Compression in applications, the following library is required: * libbrotli-dev >= 1.0.9 To enable mruby support for nghttpx, `mruby `_ is required. We need to build mruby with C++ ABI explicitly turned on, and probably need other mrgems, mruby is managed by git submodule under third-party/mruby directory. Currently, mruby support for nghttpx is disabled by default. To enable mruby support, use ``--with-mruby`` configure option. Note that at the time of this writing, libmruby-dev and mruby packages in Debian/Ubuntu are not usable for nghttp2, since they do not enable C++ ABI. To build mruby, the following packages are required: * ruby * bison nghttpx supports `neverbleed `_, privilege separation engine for OpenSSL. In short, it minimizes the risk of private key leakage when serious bug like Heartbleed is exploited. The neverbleed is disabled by default. To enable it, use ``--with-neverbleed`` configure option. To enable the experimental HTTP/3 support for h2load and nghttpx, the following libraries are required: * `quictls `_; or wolfSSL; or LibreSSL (does not support 0RTT); or aws-lc; or `BoringSSL `_ (commit 3c6315e00ab02d7bc9b8922aff1f85d8f81ee130); or OpenSSL >= 3.5.0 * `ngtcp2 `_ >= 1.23.0 * `nghttp3 `_ >= 1.17.0 Use ``--enable-http3`` configure option to enable HTTP/3 feature for h2load and nghttpx. In order to build optional eBPF program to direct an incoming QUIC UDP datagram to a correct socket for nghttpx, the following libraries are required: * libbpf-dev >= 0.7.0 Use ``--with-libbpf`` configure option to build eBPF program. libelf-dev is needed to build libbpf. For Ubuntu 20.04, you can build libbpf from `the source code `_. nghttpx requires eBPF program for reloading its configuration and hot swapping its executable. Compiling libnghttp2 C source code requires a C99 compiler. gcc 4.8 is known to be adequate. In order to compile the C++ source code, C++23 compliant compiler is required. At least g++ >= 14 and clang++ >= 19 are known to work. .. note:: To enable mruby support in nghttpx, and use ``--with-mruby`` configure option. .. note:: Mac OS X users may need the ``--disable-threads`` configure option to disable multi-threading in nghttpd, nghttpx and h2load to prevent them from crashing. A patch is welcome to make multi threading work on Mac OS X platform. .. note:: To compile the associated applications (nghttp, nghttpd, nghttpx and h2load), you must use the ``--enable-app`` configure option and ensure that the specified requirements above are met. Normally, configure script checks required dependencies to build these applications, and enable ``--enable-app`` automatically, so you don't have to use it explicitly. But if you found that applications were not built, then using ``--enable-app`` may find that cause, such as the missing dependency. .. note:: In order to detect third party libraries, pkg-config is used (however we don't use pkg-config for some libraries (e.g., libev)). By default, pkg-config searches ``*.pc`` file in the standard locations (e.g., /usr/lib/pkgconfig). If it is necessary to use ``*.pc`` file in the custom location, specify paths to ``PKG_CONFIG_PATH`` environment variable, and pass it to configure script, like so: .. code-block:: text $ ./configure PKG_CONFIG_PATH=/path/to/pkgconfig For pkg-config managed libraries, ``*_CFLAG`` and ``*_LIBS`` environment variables are defined (e.g., ``OPENSSL_CFLAGS``, ``OPENSSL_LIBS``). Specifying non-empty string to these variables completely overrides pkg-config. In other words, if they are specified, pkg-config is not used for detection, and user is responsible to specify the correct values to these variables. For complete list of these variables, run ``./configure -h``. If you are using Ubuntu 22.04 LTS, run the following to install the required packages: .. code-block:: text sudo apt-get install g++ clang make binutils autoconf automake \ autotools-dev libtool pkg-config \ zlib1g-dev libssl-dev libxml2-dev libev-dev \ libevent-dev libjansson-dev \ libc-ares-dev libjemalloc-dev libsystemd-dev \ ruby-dev bison libelf-dev Building nghttp2 from release tar archive ----------------------------------------- The nghttp2 project regularly releases tar archives which includes nghttp2 source code, and generated build files. They can be downloaded from `Releases `_ page. Building nghttp2 from git requires autotools development packages. Building from tar archives does not require them, and thus it is much easier. The usual build step is as follows: .. code-block:: text $ tar xf nghttp2-X.Y.Z.tar.bz2 $ cd nghttp2-X.Y.Z $ ./configure $ make Building from git ----------------- Building from git is easy, but please be sure that at least autoconf 2.68 is used: .. code-block:: text $ git submodule update --init $ autoreconf -i $ automake $ autoconf $ ./configure $ make Notes for building on Windows (MSVC) ------------------------------------ The easiest way to build native Windows nghttp2 dll is use `cmake `_. The free version of `Visual C++ Build Tools `_ works fine. 1. Install cmake for windows 2. Open "Visual C++ ... Native Build Tool Command Prompt", and inside nghttp2 directly, run ``cmake``. 3. Then run ``cmake --build`` to build library. 4. nghttp2.dll, nghttp2.lib, nghttp2.exp are placed under lib directory. Note that the above steps most likely produce nghttp2 library only. No bundled applications are compiled. Notes for building on Windows (Mingw/Cygwin) -------------------------------------------- Under Mingw environment, you can only compile the library, it's ``libnghttp2-X.dll`` and ``libnghttp2.a``. If you want to compile the applications(``h2load``, ``nghttp``, ``nghttpx``, ``nghttpd``), you need to use the Cygwin environment. Under Cygwin environment, to compile the applications you need to compile and install the libev first. Secondly, you need to undefine the macro ``__STRICT_ANSI__``, if you not, the functions ``fdopen``, ``fileno`` and ``strptime`` will not available. the sample command like this: .. code-block:: text $ export CFLAGS="-U__STRICT_ANSI__ -I$libev_PREFIX/include -L$libev_PREFIX/lib" $ export CXXFLAGS=$CFLAGS $ ./configure $ make If you want to compile the applications under ``examples/``, you need to remove or rename the ``event.h`` from libev's installation, because it conflicts with libevent's installation. Notes for installation on Linux systems -------------------------------------------- After installing nghttp2 tool suite with ``make install`` one might experience a similar error: .. code-block:: text nghttpx: error while loading shared libraries: libnghttp2.so.14: cannot open shared object file: No such file or directory This means that the tool is unable to locate the ``libnghttp2.so`` shared library. To update the shared library cache run ``sudo ldconfig``. Building the documentation -------------------------- .. note:: Documentation is still incomplete. To build the documentation, run: .. code-block:: text $ make html The documents will be generated under ``doc/manual/html/``. The generated documents will not be installed with ``make install``. The online documentation is available at https://nghttp2.org/documentation/ Build HTTP/3 enabled h2load and nghttpx --------------------------------------- To build h2load and nghttpx with HTTP/3 feature enabled, run the configure script with ``--enable-http3``. For nghttpx to reload configurations and swapping its executable while gracefully terminating old worker processes, eBPF is required. Run the configure script with ``--enable-http3 --with-libbpf`` to build eBPF program. The QUIC keying material must be set with ``--frontend-quic-secret-file`` in order to keep the existing connections alive during reload. The detailed steps to build HTTP/3 enabled h2load and nghttpx follow. Build aws-lc: .. code-block:: text $ git clone --depth 1 -b v5.4.0 https://github.com/aws/aws-lc $ cd aws-lc $ cmake -B build -DDISABLE_GO=ON --install-prefix=$PWD/opt $ make -j$(nproc) -C build $ cmake --install build $ cd .. Build nghttp3: .. code-block:: text $ git clone --depth 1 -b v1.18.0 https://github.com/ngtcp2/nghttp3 $ cd nghttp3 $ git submodule update --init --depth 1 $ autoreconf -i $ ./configure --prefix=$PWD/build --enable-lib-only $ make -j$(nproc) $ make install $ cd .. Build ngtcp2: .. code-block:: text $ git clone --depth 1 -b v1.25.0 https://github.com/ngtcp2/ngtcp2 $ cd ngtcp2 $ git submodule update --init --depth 1 $ autoreconf -i $ ./configure --prefix=$PWD/build --enable-lib-only --with-boringssl \ BORINGSSL_CFLAGS="-I$PWD/../aws-lc/opt/include" \ BORINGSSL_LIBS="-L$PWD/../aws-lc/opt/lib -lssl -lcrypto" $ make -j$(nproc) $ make install $ cd .. If your Linux distribution does not have libbpf-dev >= 0.7.0, build from source: .. code-block:: text $ git clone --depth 1 -b v1.7.0 https://github.com/libbpf/libbpf $ cd libbpf $ PREFIX=$PWD/build make -C src install $ cd .. Build nghttp2: .. code-block:: text $ git clone https://github.com/nghttp2/nghttp2 $ cd nghttp2 $ git submodule update --init $ autoreconf -i $ ./configure --with-mruby --enable-http3 --with-libbpf \ CC=clang-19 CXX=clang++-19 \ PKG_CONFIG_PATH="$PWD/../aws-lc/opt/lib/pkgconfig:$PWD/../nghttp3/build/lib/pkgconfig:$PWD/../ngtcp2/build/lib/pkgconfig:$PWD/../libbpf/build/lib64/pkgconfig" \ LDFLAGS="$LDFLAGS -Wl,-rpath,$PWD/../aws-lc/opt/lib -Wl,-rpath,$PWD/../libbpf/build/lib64" $ make -j$(nproc) The eBPF program ``reuseport_kern.o`` should be found under bpf directory. Pass ``--quic-bpf-program-file=bpf/reuseport_kern.o`` option to nghttpx to load it. See also `HTTP/3 section in nghttpx - HTTP/2 proxy - HOW-TO `_. Unit tests ---------- Unit tests are done by simply running ``make check``. Integration tests ----------------- We have the integration tests for the nghttpx proxy server. The tests are written in the `Go programming language `_ and uses its testing framework. We depend on the following libraries: * golang.org/x/net/http2 * golang.org/x/net/websocket * https://github.com/tatsuhiro-t/go-nghttp2 Go modules will download these dependencies automatically. To run the tests, run the following command under ``integration-tests`` directory: .. code-block:: text $ make it Inside the tests, we use port 3009 to run the test subject server. Migration from v0.7.15 or earlier --------------------------------- nghttp2 v1.0.0 introduced several backward incompatible changes. In this section, we describe these changes and how to migrate to v1.0.0. ALPN protocol ID is now ``h2`` and ``h2c`` ++++++++++++++++++++++++++++++++++++++++++ Previously we announced ``h2-14`` and ``h2c-14``. v1.0.0 implements final protocol version, and we changed ALPN ID to ``h2`` and ``h2c``. The macros ``NGHTTP2_PROTO_VERSION_ID``, ``NGHTTP2_PROTO_VERSION_ID_LEN``, ``NGHTTP2_CLEARTEXT_PROTO_VERSION_ID``, and ``NGHTTP2_CLEARTEXT_PROTO_VERSION_ID_LEN`` have been updated to reflect this change. Basically, existing applications do not have to do anything, just recompiling is enough for this change. Use word "client magic" where we use "client connection preface" ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ We use "client connection preface" to mean first 24 bytes of client connection preface. This is technically not correct, since client connection preface is composed of 24 bytes client magic byte string followed by SETTINGS frame. For clarification, we call "client magic" for this 24 bytes byte string and updated API. * ``NGHTTP2_CLIENT_CONNECTION_PREFACE`` was replaced with ``NGHTTP2_CLIENT_MAGIC``. * ``NGHTTP2_CLIENT_CONNECTION_PREFACE_LEN`` was replaced with ``NGHTTP2_CLIENT_MAGIC_LEN``. * ``NGHTTP2_BAD_PREFACE`` was renamed as ``NGHTTP2_BAD_CLIENT_MAGIC`` The already deprecated ``NGHTTP2_CLIENT_CONNECTION_HEADER`` and ``NGHTTP2_CLIENT_CONNECTION_HEADER_LEN`` were removed. If application uses these macros, just replace old ones with new ones. Since v1.0.0, client magic is sent by library (see next subsection), so client application may just remove these macro use. Client magic is sent by library +++++++++++++++++++++++++++++++ Previously nghttp2 library did not send client magic, which is first 24 bytes byte string of client connection preface, and client applications have to send it by themselves. Since v1.0.0, client magic is sent by library via first call of ``nghttp2_session_send()`` or ``nghttp2_session_mem_send2()``. The client applications which send client magic must remove the relevant code. Remove HTTP Alternative Services (Alt-Svc) related code +++++++++++++++++++++++++++++++++++++++++++++++++++++++ Alt-Svc specification is not finalized yet. To make our API stable, we have decided to remove all Alt-Svc related API from nghttp2. * ``NGHTTP2_EXT_ALTSVC`` was removed. * ``nghttp2_ext_altsvc`` was removed. We have already removed the functionality of Alt-Svc in v0.7 series and they have been essentially noop. The application using these macro and struct, remove those lines. Use nghttp2_error in nghttp2_on_invalid_frame_recv_callback +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Previously ``nghttp2_on_invalid_frame_recv_cb_called`` took the ``error_code``, defined in ``nghttp2_error_code``, as parameter. But they are not detailed enough to debug. Therefore, we decided to use more detailed ``nghttp2_error`` values instead. The application using this callback should update the callback signature. If it treats ``error_code`` as HTTP/2 error code, update the code so that it is treated as ``nghttp2_error``. Receive client magic by default +++++++++++++++++++++++++++++++ Previously nghttp2 did not process client magic (24 bytes byte string). To make it deal with it, we had to use ``nghttp2_option_set_recv_client_preface()``. Since v1.0.0, nghttp2 processes client magic by default and ``nghttp2_option_set_recv_client_preface()`` was removed. Some application may want to disable this behaviour, so we added ``nghttp2_option_set_no_recv_client_magic()`` to achieve this. The application using ``nghttp2_option_set_recv_client_preface()`` with nonzero value, just remove it. The application using ``nghttp2_option_set_recv_client_preface()`` with zero value or not using it must use ``nghttp2_option_set_no_recv_client_magic()`` with nonzero value. Client, Server and Proxy programs --------------------------------- The ``src`` directory contains the HTTP/2 client, server and proxy programs. nghttp - client +++++++++++++++ ``nghttp`` is a HTTP/2 client. It can connect to the HTTP/2 server with prior knowledge, HTTP Upgrade and ALPN TLS extension. It has verbose output mode for framing information. Here is sample output from ``nghttp`` client: .. code-block:: text $ nghttp -nv https://nghttp2.org [ 0.190] Connected The negotiated protocol: h2 [ 0.212] recv SETTINGS frame (niv=2) [SETTINGS_MAX_CONCURRENT_STREAMS(0x03):100] [SETTINGS_INITIAL_WINDOW_SIZE(0x04):65535] [ 0.212] send SETTINGS frame (niv=2) [SETTINGS_MAX_CONCURRENT_STREAMS(0x03):100] [SETTINGS_INITIAL_WINDOW_SIZE(0x04):65535] [ 0.212] send SETTINGS frame ;

By default, it uses SSL/TLS connection. Use ``--no-tls`` option to disable it. ``nghttpd`` only accepts HTTP/2 connections via ALPN or direct HTTP/2 connections. No HTTP Upgrade is supported. The ``-p`` option allows users to configure server push. Just like ``nghttp``, it has a verbose output mode for framing information. Here is sample output from ``nghttpd``: .. code-block:: text $ nghttpd --no-tls -v 8080 IPv4: listen 0.0.0.0:8080 IPv6: listen :::8080 [id=1] [ 1.521] send SETTINGS frame (niv=1) [SETTINGS_MAX_CONCURRENT_STREAMS(0x03):100] [id=1] [ 1.521] recv SETTINGS frame (niv=2) [SETTINGS_MAX_CONCURRENT_STREAMS(0x03):100] [SETTINGS_INITIAL_WINDOW_SIZE(0x04):65535] [id=1] [ 1.521] recv SETTINGS frame ; ACK (niv=0) [id=1] [ 1.521] recv PRIORITY frame (dep_stream_id=0, weight=201, exclusive=0) [id=1] [ 1.521] recv PRIORITY frame (dep_stream_id=0, weight=101, exclusive=0) [id=1] [ 1.521] recv PRIORITY frame (dep_stream_id=0, weight=1, exclusive=0) [id=1] [ 1.521] recv PRIORITY frame (dep_stream_id=7, weight=1, exclusive=0) [id=1] [ 1.521] recv PRIORITY frame (dep_stream_id=3, weight=1, exclusive=0) [id=1] [ 1.521] recv (stream_id=13) :method: GET [id=1] [ 1.521] recv (stream_id=13) :path: / [id=1] [ 1.521] recv (stream_id=13) :scheme: http [id=1] [ 1.521] recv (stream_id=13) :authority: localhost:8080 [id=1] [ 1.521] recv (stream_id=13) accept: */* [id=1] [ 1.521] recv (stream_id=13) accept-encoding: gzip, deflate [id=1] [ 1.521] recv (stream_id=13) user-agent: nghttp2/1.0.0-DEV [id=1] [ 1.521] recv HEADERS frame ; END_STREAM | END_HEADERS | PRIORITY (padlen=0, dep_stream_id=11, weight=16, exclusive=0) ; Open new stream [id=1] [ 1.521] send SETTINGS frame ; ACK (niv=0) [id=1] [ 1.521] send HEADERS frame ; END_HEADERS (padlen=0) ; First response header :status: 200 server: nghttpd nghttp2/1.0.0-DEV content-length: 10 cache-control: max-age=3600 date: Fri, 15 May 2015 14:49:04 GMT last-modified: Tue, 30 Sep 2014 12:40:52 GMT [id=1] [ 1.522] send DATA frame ; END_STREAM [id=1] [ 1.522] stream_id=13 closed [id=1] [ 1.522] recv GOAWAY frame (last_stream_id=0, error_code=NO_ERROR(0x00), opaque_data(0)=[]) [id=1] [ 1.522] closed nghttpx - proxy +++++++++++++++ ``nghttpx`` is a multi-threaded reverse proxy for HTTP/3, HTTP/2, and HTTP/1.1, and powers http://nghttp2.org and supports HTTP/2 server push. We reworked ``nghttpx`` command-line interface, and as a result, there are several incompatibles from 1.8.0 or earlier. This is necessary to extend its capability, and secure the further feature enhancements in the future release. Please read `Migration from nghttpx v1.8.0 or earlier `_ to know how to migrate from earlier releases. ``nghttpx`` implements `important performance-oriented features `_ in TLS, such as session IDs, session tickets (with automatic key rotation), dynamic record sizing, ALPN, forward secrecy and HTTP/2. ``nghttpx`` also offers the functionality to share ticket keys among multiple ``nghttpx`` instances via memcached. ``nghttpx`` has 2 operation modes: ================== ======================== ================ ============= Mode option Frontend Backend Note ================== ======================== ================ ============= default mode HTTP/3, HTTP/2, HTTP/1.1 HTTP/1.1, HTTP/2 Reverse proxy ``--http2-proxy`` HTTP/3, HTTP/2, HTTP/1.1 HTTP/1.1, HTTP/2 Forward proxy ================== ======================== ================ ============= The interesting mode at the moment is the default mode. It works like a reverse proxy and listens for HTTP/3, HTTP/2, and HTTP/1.1 and can be deployed as a SSL/TLS terminator for existing web server. In all modes, the frontend connections are encrypted by SSL/TLS by default. To disable encryption, use the ``no-tls`` keyword in ``--frontend`` option. If encryption is disabled, incoming HTTP/1.1 connections can be upgraded to HTTP/2 through HTTP Upgrade. On the other hard, backend connections are not encrypted by default. To encrypt backend connections, use ``tls`` keyword in ``--backend`` option. ``nghttpx`` supports a configuration file. See the ``--conf`` option and sample configuration file ``nghttpx.conf.sample``. In the default mode, ``nghttpx`` works as reverse proxy to the backend server: .. code-block:: text Client <-- (HTTP/3, HTTP/2, HTTP/1.1) --> nghttpx <-- (HTTP/1.1, HTTP/2) --> Web Server [reverse proxy] With the ``--http2-proxy`` option, it works as forward proxy, and it is so called secure HTTP/2 proxy: .. code-block:: text Client <-- (HTTP/3, HTTP/2, HTTP/1.1) --> nghttpx <-- (HTTP/1.1) --> Proxy [secure proxy] (e.g., Squid, ATS) The ``Client`` in the above example needs to be configured to use ``nghttpx`` as secure proxy. At the time of this writing, both Chrome and Firefox support secure HTTP/2 proxy. One way to configure Chrome to use a secure proxy is to create a proxy.pac script like this: .. code-block:: javascript function FindProxyForURL(url, host) { return "HTTPS SERVERADDR:PORT"; } ``SERVERADDR`` and ``PORT`` is the hostname/address and port of the machine nghttpx is running on. Please note that Chrome requires a valid certificate for secure proxy. Then run Chrome with the following arguments: .. code-block:: text $ google-chrome --proxy-pac-url=file:///path/to/proxy.pac --use-npn The backend HTTP/2 connections can be tunneled through an HTTP proxy. The proxy is specified using ``--backend-http-proxy-uri``. The following figure illustrates how nghttpx talks to the outside HTTP/2 proxy through an HTTP proxy: .. code-block:: text Client <-- (HTTP/3, HTTP/2, HTTP/1.1) --> nghttpx <-- (HTTP/2) -- --===================---> HTTP/2 Proxy (HTTP proxy tunnel) (e.g., nghttpx -s) Benchmarking tool ----------------- The ``h2load`` program is a benchmarking tool for HTTP/3, HTTP/2, and HTTP/1.1. The UI of ``h2load`` is heavily inspired by ``weighttp`` (https://github.com/lighttpd/weighttp). The typical usage is as follows: .. code-block:: text $ h2load -n100000 -c100 -m100 https://localhost:8443/ starting benchmark... spawning thread #0: 100 concurrent clients, 100000 total requests Protocol: TLSv1.2 Cipher: ECDHE-RSA-AES128-GCM-SHA256 Server Temp Key: ECDH P-256 256 bits progress: 10% done progress: 20% done progress: 30% done progress: 40% done progress: 50% done progress: 60% done progress: 70% done progress: 80% done progress: 90% done progress: 100% done finished in 771.26ms, 129658 req/s, 4.71MB/s requests: 100000 total, 100000 started, 100000 done, 100000 succeeded, 0 failed, 0 errored status codes: 100000 2xx, 0 3xx, 0 4xx, 0 5xx traffic: 3812300 bytes total, 1009900 bytes headers, 1000000 bytes data min max mean sd +/- sd time for request: 25.12ms 124.55ms 51.07ms 15.36ms 84.87% time for connect: 208.94ms 254.67ms 241.38ms 7.95ms 63.00% time to 1st byte: 209.11ms 254.80ms 241.51ms 7.94ms 63.00% The above example issued total 100,000 requests, using 100 concurrent clients (in other words, 100 HTTP/2 sessions), and a maximum of 100 streams per client. With the ``-t`` option, ``h2load`` will use multiple native threads to avoid saturating a single core on client side. .. warning:: **Don't use this tool against publicly available servers.** That is considered a DOS attack. Please only use it against your private servers. If the experimental HTTP/3 is enabled, h2load can send requests to HTTP/3 server. To do this, use ``--h3`` option (or ``--alpn-list=h3`` option) like so: .. code-block:: text $ h2load --h3 https://127.0.0.1:4433 For nghttp2 v1.58 or earlier, use ``--npn-list`` instead of ``--alpn-list``. HPACK tools ----------- The ``src`` directory contains the HPACK tools. The ``deflatehd`` program is a command-line header compression tool. The ``inflatehd`` program is a command-line header decompression tool. Both tools read input from stdin and write output to stdout. Errors are written to stderr. They take JSON as input and output. We (mostly) use the same JSON data format described at https://github.com/http2jp/hpack-test-case. deflatehd - header compressor +++++++++++++++++++++++++++++ The ``deflatehd`` program reads JSON data or HTTP/1-style header fields from stdin and outputs compressed header block in JSON. For the JSON input, the root JSON object must include a ``cases`` key. Its value has to include the sequence of input header set. They share the same compression context and are processed in the order they appear. Each item in the sequence is a JSON object and it must include a ``headers`` key. Its value is an array of JSON objects, which includes exactly one name/value pair. Example: .. code-block:: json { "cases": [ { "headers": [ { ":method": "GET" }, { ":path": "/" } ] }, { "headers": [ { ":method": "POST" }, { ":path": "/" } ] } ] } With the ``-t`` option, the program can accept more familiar HTTP/1 style header field blocks. Each header set is delimited by an empty line: Example: .. code-block:: text :method: GET :scheme: https :path: / :method: POST user-agent: nghttp2 The output is in JSON object. It should include a ``cases`` key and its value is an array of JSON objects, which has at least the following keys: seq The index of header set in the input. input_length The sum of the length of the name/value pairs in the input. output_length The length of the compressed header block. percentage_of_original_size ``output_length`` / ``input_length`` * 100 wire The compressed header block as a hex string. headers The input header set. header_table_size The header table size adjusted before deflating the header set. Examples: .. code-block:: json { "cases": [ { "seq": 0, "input_length": 66, "output_length": 20, "percentage_of_original_size": 30.303030303030305, "wire": "01881f3468e5891afcbf83868a3d856659c62e3f", "headers": [ { ":authority": "example.org" }, { ":method": "GET" }, { ":path": "/" }, { ":scheme": "https" }, { "user-agent": "nghttp2" } ], "header_table_size": 4096 } , { "seq": 1, "input_length": 74, "output_length": 10, "percentage_of_original_size": 13.513513513513514, "wire": "88448504252dd5918485", "headers": [ { ":authority": "example.org" }, { ":method": "POST" }, { ":path": "/account" }, { ":scheme": "https" }, { "user-agent": "nghttp2" } ], "header_table_size": 4096 } ] } The output can be used as the input for ``inflatehd`` and ``deflatehd``. With the ``-d`` option, the extra ``header_table`` key is added and its associated value includes the state of dynamic header table after the corresponding header set was processed. The value includes at least the following keys: entries The entry in the header table. If ``referenced`` is ``true``, it is in the reference set. The ``size`` includes the overhead (32 bytes). The ``index`` corresponds to the index of header table. The ``name`` is the header field name and the ``value`` is the header field value. size The sum of the spaces entries occupied, this includes the entry overhead. max_size The maximum header table size. deflate_size The sum of the spaces entries occupied within ``max_deflate_size``. max_deflate_size The maximum header table size the encoder uses. This can be smaller than ``max_size``. In this case, the encoder only uses up to first ``max_deflate_size`` buffer. Since the header table size is still ``max_size``, the encoder has to keep track of entries outside the ``max_deflate_size`` but inside the ``max_size`` and make sure that they are no longer referenced. Example: .. code-block:: json { "cases": [ { "seq": 0, "input_length": 66, "output_length": 20, "percentage_of_original_size": 30.303030303030305, "wire": "01881f3468e5891afcbf83868a3d856659c62e3f", "headers": [ { ":authority": "example.org" }, { ":method": "GET" }, { ":path": "/" }, { ":scheme": "https" }, { "user-agent": "nghttp2" } ], "header_table_size": 4096, "header_table": { "entries": [ { "index": 1, "name": "user-agent", "value": "nghttp2", "referenced": true, "size": 49 }, { "index": 2, "name": ":scheme", "value": "https", "referenced": true, "size": 44 }, { "index": 3, "name": ":path", "value": "/", "referenced": true, "size": 38 }, { "index": 4, "name": ":method", "value": "GET", "referenced": true, "size": 42 }, { "index": 5, "name": ":authority", "value": "example.org", "referenced": true, "size": 53 } ], "size": 226, "max_size": 4096, "deflate_size": 226, "max_deflate_size": 4096 } } , { "seq": 1, "input_length": 74, "output_length": 10, "percentage_of_original_size": 13.513513513513514, "wire": "88448504252dd5918485", "headers": [ { ":authority": "example.org" }, { ":method": "POST" }, { ":path": "/account" }, { ":scheme": "https" }, { "user-agent": "nghttp2" } ], "header_table_size": 4096, "header_table": { "entries": [ { "index": 1, "name": ":method", "value": "POST", "referenced": true, "size": 43 }, { "index": 2, "name": "user-agent", "value": "nghttp2", "referenced": true, "size": 49 }, { "index": 3, "name": ":scheme", "value": "https", "referenced": true, "size": 44 }, { "index": 4, "name": ":path", "value": "/", "referenced": false, "size": 38 }, { "index": 5, "name": ":method", "value": "GET", "referenced": false, "size": 42 }, { "index": 6, "name": ":authority", "value": "example.org", "referenced": true, "size": 53 } ], "size": 269, "max_size": 4096, "deflate_size": 269, "max_deflate_size": 4096 } } ] } inflatehd - header decompressor +++++++++++++++++++++++++++++++ The ``inflatehd`` program reads JSON data from stdin and outputs decompressed name/value pairs in JSON. The root JSON object must include the ``cases`` key. Its value has to include the sequence of compressed header blocks. They share the same compression context and are processed in the order they appear. Each item in the sequence is a JSON object and it must have at least a ``wire`` key. Its value is a compressed header block as a hex string. Example: .. code-block:: json { "cases": [ { "wire": "8285" }, { "wire": "8583" } ] } The output is a JSON object. It should include a ``cases`` key and its value is an array of JSON objects, which has at least following keys: seq The index of the header set in the input. headers A JSON array that includes decompressed name/value pairs. wire The compressed header block as a hex string. header_table_size The header table size adjusted before inflating compressed header block. Example: .. code-block:: json { "cases": [ { "seq": 0, "wire": "01881f3468e5891afcbf83868a3d856659c62e3f", "headers": [ { ":authority": "example.org" }, { ":method": "GET" }, { ":path": "/" }, { ":scheme": "https" }, { "user-agent": "nghttp2" } ], "header_table_size": 4096 } , { "seq": 1, "wire": "88448504252dd5918485", "headers": [ { ":method": "POST" }, { ":path": "/account" }, { "user-agent": "nghttp2" }, { ":scheme": "https" }, { ":authority": "example.org" } ], "header_table_size": 4096 } ] } The output can be used as the input for ``deflatehd`` and ``inflatehd``. With the ``-d`` option, the extra ``header_table`` key is added and its associated value includes the state of the dynamic header table after the corresponding header set was processed. The format is the same as ``deflatehd``. Contribution ------------ [This text was composed based on 1.2.

GENERATED by help2rst.py. DO NOT EDIT DIRECTLY. .. program:: nghttp nghttp(1) ========= SYNOPSIS -------- **nghttp** [OPTIONS]... ... DESCRIPTION ----------- HTTP/2 client .. describe:: Specify URI to access. OPTIONS ------- .. option:: -v, --verbose Print debug information such as reception and transmission of frames and name/value pairs. Specifying this option multiple times increases verbosity. .. option:: -n, --null-out Discard downloaded data. .. option:: -O, --remote-name Save download data in the current directory. The filename is derived from URI. If URI ends with '*/*', 'index.html' is used as a filename. Not implemented yet. .. option:: -t, --timeout= Timeout each request after . Set 0 to disable timeout. .. option:: -w, --window-bits= Sets the stream level initial window size to 2\*\*-1. .. option:: -W, --connection-window-bits= Sets the connection level initial window size to 2\*\*-1. .. option:: -a, --get-assets Download assets such as stylesheets, images and script files linked from the downloaded resource. Only links whose origins are the same with the linking resource will be downloaded. nghttp prioritizes resources using HTTP/2 dependency based priority. The priority order, from highest to lowest, is html itself, css, javascript and images. .. option:: -s, --stat Print statistics. .. option:: -H, --header=
Add a header to the requests. Example: :option:`-H`\':method: PUT' .. option:: --trailer=
Add a trailer header to the requests.
must not include pseudo header field (header field name starting with ':'). To send trailer, one must use :option:`-d` option to send request body. Example: :option:`--trailer` 'foo: bar'. .. option:: --cert= Use the specified client certificate file. The file must be in PEM format. .. option:: --key= Use the client private key file. The file must be in PEM format. .. option:: -d, --data= Post FILE to server. If '-' is given, data will be read from stdin. .. option:: -m, --multiply= Request each URI times. By default, same URI is not requested twice. This option disables it too. .. option:: -u, --upgrade Perform HTTP Upgrade for HTTP/2. This option is ignored if the request URI has https scheme. If :option:`-d` is used, the HTTP upgrade request is performed with OPTIONS method. .. option:: --extpri= Sets RFC 9218 priority of given URI. must be the wire format of priority header field (e.g., "u=3,i"). This option can be used multiple times, and N-th :option:`--extpri` option sets priority of N-th URI in the command line. If the number of this option is less than the number of URI, the last option value is repeated. If there is no :option:`--extpri` option, urgency is 3, and incremental is false. .. option:: -M, --peer-max-concurrent-streams= Use as SETTINGS_MAX_CONCURRENT_STREAMS value of remote endpoint as if it is received in SETTINGS frame. Default: ``100`` .. option:: -c, --header-table-size= Specify decoder header table size. If this option is used multiple times, and the minimum value among the given values except for last one is strictly less than the last value, that minimum value is set in SETTINGS frame payload before the last value, to simulate multiple header table size change. .. option:: --encoder-header-table-size= Specify encoder header table size. The decoder (server) specifies the maximum dynamic table size it accepts. Then the negotiated dynamic table size is the minimum of this option value and the value which server specified. .. option:: -b, --padding= Add at most bytes to a frame payload as padding. Specify 0 to disable padding. .. option:: -r, --har= Output HTTP transactions in HAR format. If '-' is given, data is written to stdout. .. option:: --color Force colored log output. .. option:: --continuation Send large header to test CONTINUATION. .. option:: --no-content-length Don't send content-length header field. .. option:: --hexdump Display the incoming traffic in hexadecimal (Canonical hex+ASCII display). If SSL/TLS is used, decrypted data are used. .. option:: --no-push Disable server push. .. option:: --max-concurrent-streams= The number of concurrent pushed streams this client accepts. .. option:: --expect-continue Perform an Expect/Continue handshake: wait to send DATA (up to a short timeout) until the server sends a 100 Continue interim response. This option is ignored unless combined with the :option:`-d` option. .. option:: -y, --no-verify-peer Suppress warning on server certificate verification failure. .. option:: --ktls Enable ktls. .. option:: --version Display version information and exit. .. option:: -h, --help Display this help and exit. The argument is an integer and an optional unit (e.g., 10K is 10 * 1024). Units are K, M and G (powers of 1024). The argument is an integer and an optional unit (e.g., 1s is 1 second and 500ms is 500 milliseconds). Units are h, m, s or ms (hours, minutes, seconds and milliseconds, respectively). If a unit is omitted, a second is used as unit.

This means that the client application code does not need to submit SETTINGS by itself. The stream with stream ID=1 is opened and the *stream_user_data* is used for its stream_user_data.

If called from server side, the *settings_payload* must be the value received in ``HTTP2-Settings`` header field and must be decoded by base64url decoder.

The *in* contains peer's protocol list in preferable order. The format of *in* is length-prefixed and not null-terminated. For example, ``h2`` and ``http/1.1`` stored in *in* like this:: in[0] = 2 in[1..2] = "h2" in[3] = 8 in[4..11] = "http/1.1" inlen = 12 The selection algorithm is as follows: 1. If peer's list contains HTTP/2 protocol the library supports, it is selected and returns 1. The following step is not taken. 2. If peer's list contains ``http/1.1``, this function selects ``http/1.1`` and returns 0. The following step is not taken. 3. This function selects nothing and returns -1 (So called non-overlap case). In this case, *out* and *outlen* are left untouched. Selecting ``h2`` means that ``h2`` is written into *\*out* and its length (which is 2) is assigned to *\*outlen*. For ALPN, refer to https://tools.ietf.org/html/rfc7301 To use this method you should do something like:: static int alpn_select_proto_cb(SSL* ssl, const unsigned char **out, unsigned char *outlen, const unsigned char *in, unsigned int inlen, void *arg) { int rv; rv = nghttp2_select_alpn(out, outlen, in, inlen); if (rv == -1) { return SSL_TLSEXT_ERR_NOACK; } if (rv == 1) { ((MyType*)arg)->http2_selected = 1; } return SSL_TLSEXT_ERR_OK; } ...

The *nva* is an array of name/value pair :type:`nghttp2_nv` with *nvlen* elements. The application is responsible to include required pseudo-header fields (header field whose name starts with ":") in *nva* and must place pseudo-headers before regular header fields. This function creates copies of all name/value pairs in *nva*. It also lower-cases all names in *nva*. The order of elements in *nva* is preserved. For header fields with :enum:`nghttp2_nv_flag.NGHTTP2_NV_FLAG_NO_COPY_NAME` and :enum:`nghttp2_nv_flag.NGHTTP2_NV_FLAG_NO_COPY_VALUE` are set, header field name and value are not copied respectively. With :enum:`nghttp2_nv_flag.NGHTTP2_NV_FLAG_NO_COPY_NAME`, application is responsible to pass header field name in lowercase. The application should maintain the references to them until :type:`nghttp2_on_frame_send_callback` or :type:`nghttp2_on_frame_not_send_callback` is called. HTTP/2 specification has requirement about header fields in the response HEADERS. See the specification for more details. If *data_prd* is not ``NULL``, it provides data which will be sent in subsequent DATA frames. This function does not take ownership of the *data_prd*. The function copies the members of the *data_prd*. If *data_prd* is ``NULL``, HEADERS will have END_STREAM flag set. This method can be used as normal HTTP response and push response. When pushing a resource using this function, the *session* must be configured using `nghttp2_session_server_new()` or its variants and the target stream denoted by the *stream_id* must be reserved using `nghttp2_submit_push_promise()`. To send non-final response headers (e.g., HTTP status 101), don't use this function because this function half-closes the outbound stream. Instead, use `nghttp2_submit_headers()` for this purpose. This function returns 0 if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. :enum:`nghttp2_error.NGHTTP2_ERR_INVALID_ARGUMENT` The *stream_id* is 0. :enum:`nghttp2_error.NGHTTP2_ERR_DATA_EXIST` DATA or HEADERS has been already submitted and not fully processed yet.

Required unless :option:`--no-tls` is specified. .. describe:: Set path to server's certificate. Required unless :option:`--no-tls` is specified. OPTIONS ------- .. option:: -a, --address= The address to bind to. If not specified the default IP address determined by getaddrinfo is used. .. option:: -D, --daemon Run in a background. If :option:`-D` is used, the current working directory is changed to '*/*'. Therefore if this option is used, :option:`-d` option must be specified. .. option:: -V, --verify-client The server sends a client certificate request. If the client did not return a certificate, the handshake is terminated. Currently, this option just requests a client certificate and does not verify it. .. option:: -d, --htdocs= Specify document root. If this option is not specified, the document root is the current working directory. .. option:: -v, --verbose Print debug information such as reception/ transmission of frames and name/value pairs. .. option:: --no-tls Disable SSL/TLS. .. option:: -c, --header-table-size= Specify decoder header table size. .. option:: --encoder-header-table-size= Specify encoder header table size. The decoder (client) specifies the maximum dynamic table size it accepts. Then the negotiated dynamic table size is the minimum of this option value and the value which client specified. .. option:: --color Force colored log output. .. option:: -p, --push== Push resources s when is requested. This option can be used repeatedly to specify multiple push configurations. and s are relative to document root. See :option:`--htdocs` option. Example: :option:`-p`\/=/foo.png :option:`-p`\/doc=/bar.css .. option:: -b, --padding= Add at most bytes to a frame payload as padding. Specify 0 to disable padding. .. option:: -m, --max-concurrent-streams= Set the maximum number of the concurrent streams in one HTTP/2 session. Default: ``100`` .. option:: -n, --workers= Set the number of worker threads. Default: ``1`` .. option:: -e, --error-gzip Make error response gzipped. .. option:: -w, --window-bits= Sets the stream level initial window size to 2\*\*-1. .. option:: -W, --connection-window-bits= Sets the connection level initial window size to 2\*\*-1. .. option:: --dh-param-file= Path to file that contains DH parameters in PEM format. Without this option, DHE cipher suites are not available. .. option:: --early-response Start sending response when request HEADERS is received, rather than complete request is received. .. option:: --trailer=
Add a trailer header to a response.
must not include pseudo header field (header field name starting with ':'). The trailer is sent only if a response has body part. Example: :option:`--trailer` 'foo: bar'. .. option:: --hexdump Display the incoming traffic in hexadecimal (Canonical hex+ASCII display). If SSL/TLS is used, decrypted data are used. .. option:: --echo-upload Send back uploaded content if method is POST or PUT. .. option:: --mime-types-file= Path to file that contains MIME media types and the extensions that represent them. Default: ``/etc/mime.types`` .. option:: --no-content-length Don't send content-length header field. .. option:: --groups= Specify the supported groups. Default: ``X25519:P-256:P-384:P-521`` .. option:: --ktls Enable ktls. .. option:: --version Display version information and exit. .. option:: -h, --help Display this help and exit. The argument is an integer and an optional unit (e.g., 10K is 10 * 1024). Units are K, M and G (powers of 1024).

It is also subject to the connection level flow control. So the actual amount of data to send is min(`nghttp2_session_get_stream_local_window_size()`, `nghttp2_session_get_local_window_size()`).

The pre-defined error code is one of :enum:`nghttp2_error_code`. The *flags* is currently ignored and should be :enum:`nghttp2_flag.NGHTTP2_FLAG_NONE`. The *last_stream_id* is peer's stream ID or 0. So if *session* is initialized as client, *last_stream_id* must be even or 0. If *session* is initialized as server, *last_stream_id* must be odd or 0. The HTTP/2 specification says last_stream_id must not be increased from the value previously sent. So the actual value sent as last_stream_id is the minimum value between the given *last_stream_id* and the last_stream_id previously sent to the peer. If the *opaque_data* is not ``NULL`` and *opaque_data_len* is not zero, those data will be sent as additional debug data. The library makes a copy of the memory region pointed by *opaque_data* with the length *opaque_data_len*, so the caller does not need to keep this memory after the return of this function. If the *opaque_data_len* is 0, the *opaque_data* could be ``NULL``. After successful transmission of GOAWAY, following things happen. All incoming streams having strictly more than *last_stream_id* are closed. All incoming HEADERS which starts new stream are simply ignored. After all active streams are handled, both `nghttp2_session_want_read()` and `nghttp2_session_want_write()` return 0 and the application can close session. This function returns 0 if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. :enum:`nghttp2_error.NGHTTP2_ERR_INVALID_ARGUMENT` The *opaque_data_len* is too large; the *last_stream_id* is invalid. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_hd_deflate_change_table_size.rst0000644000000000000000000000013215232371110022770 xustar0030 mtime=1785328200.985359951 30 atime=1785328201.056796298 30 ctime=1785328204.517849275 nghttp2-1.70.0/doc/nghttp2_hd_deflate_change_table_size.rst0000644000175100017510000000175215232371110023365 0ustar00runnerrunner nghttp2_hd_deflate_change_table_size ==================================== Synopsis -------- *#include * .. function:: int nghttp2_hd_deflate_change_table_size(nghttp2_hd_deflater *deflater, size_t settings_max_dynamic_table_size) Changes header table size of the *deflater* to *settings_max_dynamic_table_size* bytes. This may trigger eviction in the dynamic table. The *settings_max_dynamic_table_size* should be the value received in SETTINGS_HEADER_TABLE_SIZE. The deflater never uses more memory than ``max_deflate_dynamic_table_size`` bytes specified in `nghttp2_hd_deflate_new()`.

The *frame* is a DATA frame to send. The *framehd* is the serialized frame header (9 bytes). The *length* is the length of application data to send (this does not include padding). The *source* is the same pointer passed to :type:`nghttp2_data_source_read_callback`. The application first must send frame header *framehd* of length 9 bytes. If ``frame->data.padlen > 0``, send 1 byte of value ``frame->data.padlen - 1``. Then send exactly *length* bytes of application data. Finally, if ``frame->data.padlen > 1``, send ``frame->data.padlen - 1`` bytes of zero as padding. The application has to send complete DATA frame in this callback. If all data were written successfully, return 0. If it cannot send any data at all, just return :enum:`nghttp2_error.NGHTTP2_ERR_WOULDBLOCK`; the library will call this callback with the same parameters later (It is recommended to send complete DATA frame at once in this function to deal with error; if partial frame data has already sent, it is impossible to send another data in that state, and all we can do is tear down connection).

The *user_data* pointer is the third argument passed in to the call to `nghttp2_session_client_new()` or `nghttp2_session_server_new()`. If frame is HEADERS or PUSH_PROMISE, the ``nva`` and ``nvlen`` member of their data structure are always ``NULL`` and 0 respectively. The header name/value pairs are emitted via :type:`nghttp2_on_header_callback`. Only HEADERS and DATA frame can signal the end of incoming data.

The error is indicated by the *lib_error_code*, which is one of the values defined in :type:`nghttp2_error`. When this callback function is invoked, the library automatically submits either RST_STREAM or GOAWAY frame.

The *stream_id* is the stream ID this DATA frame belongs to. The *flags* is the flags of DATA frame which this data chunk is contained. ``(flags & NGHTTP2_FLAG_END_STREAM) != 0`` does not necessarily mean this chunk of data is the last one in the stream. You should use :type:`nghttp2_on_frame_recv_callback` to know all data frames are received. The *user_data* pointer is the third argument passed in to the call to `nghttp2_session_client_new()` or `nghttp2_session_server_new()`.

The *user_data* pointer is the third argument passed in to the call to `nghttp2_session_client_new()` or `nghttp2_session_server_new()`. The implementation of this function must return 0 if it succeeds. It can also return :enum:`nghttp2_error.NGHTTP2_ERR_CANCEL` to cancel the transmission of the given frame. If there is a fatal error while executing this callback, the implementation should return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`, which makes `nghttp2_session_send()` and `nghttp2_session_mem_send2()` functions immediately return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. If the other value is returned, it is treated as if :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE` is returned. But the implementation should not rely on this since the library may define new return value to extend its capability. To set this callback to :type:`nghttp2_session_callbacks`, use `nghttp2_session_callbacks_set_before_frame_send_callback()`. .. type:: int (*nghttp2_on_frame_send_callback)(nghttp2_session *session, const nghttp2_frame *frame, void *user_data) Callback function invoked after the frame *frame* is sent. The *user_data* pointer is the third argument passed in to the call to `nghttp2_session_client_new()` or `nghttp2_session_server_new()`.

If nonzero is returned, it is treated as fatal error and `nghttp2_session_send()` and `nghttp2_session_mem_send2()` functions immediately return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. To set this callback to :type:`nghttp2_session_callbacks`, use `nghttp2_session_callbacks_set_on_frame_send_callback()`. .. type:: int (*nghttp2_on_frame_not_send_callback)(nghttp2_session *session, const nghttp2_frame *frame, int lib_error_code, void *user_data) Callback function invoked after the non-DATA frame *frame* is not sent because of the error. The error is indicated by the *lib_error_code*, which is one of the values defined in :type:`nghttp2_error`. The *user_data* pointer is the third argument passed in to the call to `nghttp2_session_client_new()` or `nghttp2_session_server_new()`. The implementation of this function must return 0 if it succeeds. If nonzero is returned, it is treated as fatal error and `nghttp2_session_send()` and `nghttp2_session_mem_send2()` functions immediately return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. `nghttp2_session_get_stream_user_data()` can be used to get associated data.

The stream_user_data, which was specified in `nghttp2_submit_request2()` or `nghttp2_submit_headers()`, is still available in this function. The *user_data* pointer is the third argument passed in to the call to `nghttp2_session_client_new()` or `nghttp2_session_server_new()`. This function is also called for a stream in reserved state. The implementation of this function must return 0 if it succeeds. If nonzero is returned, it is treated as fatal error and `nghttp2_session_recv()`, `nghttp2_session_mem_recv2()`, `nghttp2_session_send()`, and `nghttp2_session_mem_send2()` functions immediately return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. To set this callback to :type:`nghttp2_session_callbacks`, use `nghttp2_session_callbacks_set_on_stream_close_callback()`. .. type:: int (*nghttp2_on_begin_headers_callback)(nghttp2_session *session, const nghttp2_frame *frame, void *user_data) Callback function invoked when the reception of header block in HEADERS or PUSH_PROMISE is started. Each header name/value pair will be emitted by :type:`nghttp2_on_header_callback`. The ``frame->hd.flags`` may not have :enum:`nghttp2_flag.NGHTTP2_FLAG_END_HEADERS` flag set, which indicates that one or more CONTINUATION frames are involved. But the application does not need to care about that because the header name/value pairs are emitted transparently regardless of CONTINUATION frames. The server applications probably create an object to store information about new stream if ``frame->hd.type == NGHTTP2_HEADERS`` and ``frame->headers.cat == NGHTTP2_HCAT_REQUEST``. If *session* is configured as server side, ``frame->headers.cat`` is either ``NGHTTP2_HCAT_REQUEST`` containing request headers or ``NGHTTP2_HCAT_HEADERS`` containing trailer fields and never get PUSH_PROMISE in this callback. For the client applications, ``frame->hd.type`` is either ``NGHTTP2_HEADERS`` or ``NGHTTP2_PUSH_PROMISE``. In case of ``NGHTTP2_HEADERS``, ``frame->headers.cat == NGHTTP2_HCAT_RESPONSE`` means that it is the first response headers, but it may be non-final response which is indicated by 1xx status code. In this case, there may be zero or more HEADERS frame with ``frame->headers.cat == NGHTTP2_HCAT_HEADERS`` which has non-final response code and finally client gets exactly one HEADERS frame with ``frame->headers.cat == NGHTTP2_HCAT_HEADERS`` containing final response headers (non-1xx status code). The trailer fields also has ``frame->headers.cat == NGHTTP2_HCAT_HEADERS`` which does not contain any status code. Returning :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` will close the stream (promised stream if frame is PUSH_PROMISE) by issuing RST_STREAM with :enum:`nghttp2_error_code.NGHTTP2_INTERNAL_ERROR`. In this case, :type:`nghttp2_on_header_callback` and :type:`nghttp2_on_frame_recv_callback` will not be invoked. If a different error code is desirable, use `nghttp2_submit_rst_stream()` with a desired error code and then return :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. Again, use ``frame->push_promise.promised_stream_id`` as stream_id parameter in `nghttp2_submit_rst_stream()` if frame is PUSH_PROMISE. The implementation of this function must return 0 if it succeeds. It can return :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` to reset the stream (promised stream if frame is PUSH_PROMISE). For critical errors, it must return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. If the other value is returned, it is treated as if :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE` is returned. If :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE` is returned, `nghttp2_session_mem_recv2()` function will immediately return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. To set this callback to :type:`nghttp2_session_callbacks`, use `nghttp2_session_callbacks_set_on_begin_headers_callback()`. .. type:: int (*nghttp2_on_header_callback)(nghttp2_session *session, const nghttp2_frame *frame, const uint8_t *name, size_t namelen, const uint8_t *value, size_t valuelen, uint8_t flags, void *user_data) Callback function invoked when a header name/value pair is received for the *frame*. The *name* of length *namelen* is header name. The *value* of length *valuelen* is header value. The *flags* is bitwise OR of one or more of :type:`nghttp2_nv_flag`. If :enum:`nghttp2_nv_flag.NGHTTP2_NV_FLAG_NO_INDEX` is set in *flags*, the receiver must not index this name/value pair when forwarding it to the next hop. More specifically, "Literal Header Field never Indexed" representation must be used in HPACK encoding. When this callback is invoked, ``frame->hd.type`` is either :enum:`nghttp2_frame_type.NGHTTP2_HEADERS` or :enum:`nghttp2_frame_type.NGHTTP2_PUSH_PROMISE`. After all header name/value pairs are processed with this callback, and no error has been detected, :type:`nghttp2_on_frame_recv_callback` will be invoked. If there is an error in decompression, :type:`nghttp2_on_frame_recv_callback` for the *frame* will not be invoked. Both *name* and *value* are guaranteed to be NULL-terminated. The *namelen* and *valuelen* do not include terminal NULL. If `nghttp2_option_set_no_http_messaging()` is used with nonzero value, NULL character may be included in *name* or *value* before terminating NULL. Please note that unless `nghttp2_option_set_no_http_messaging()` is used, nghttp2 library does perform validation against the *name* and the *value* using `nghttp2_check_header_name()` and `nghttp2_check_header_value()`. In addition to this, nghttp2 performs validation based on HTTP Messaging rule, which is briefly explained in :ref:`http-messaging` section. If the application uses `nghttp2_session_mem_recv2()`, it can return :enum:`nghttp2_error.NGHTTP2_ERR_PAUSE` to make `nghttp2_session_mem_recv2()` return without processing further input bytes. The memory pointed by *frame*, *name* and *value* parameters are retained until `nghttp2_session_mem_recv2()` or `nghttp2_session_recv()` is called. The application must retain the input bytes which was used to produce these parameters, because it may refer to the memory region included in the input bytes. Returning :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` will close the stream (promised stream if frame is PUSH_PROMISE) by issuing RST_STREAM with :enum:`nghttp2_error_code.NGHTTP2_INTERNAL_ERROR`. In this case, :type:`nghttp2_on_header_callback` and :type:`nghttp2_on_frame_recv_callback` will not be invoked. If a different error code is desirable, use `nghttp2_submit_rst_stream()` with a desired error code and then return :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. Again, use ``frame->push_promise.promised_stream_id`` as stream_id parameter in `nghttp2_submit_rst_stream()` if frame is PUSH_PROMISE. The implementation of this function must return 0 if it succeeds. It may return :enum:`nghttp2_error.NGHTTP2_ERR_PAUSE` or :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. For other critical failures, it must return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. If the other nonzero value is returned, it is treated as :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. If :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE` is returned, `nghttp2_session_recv()` and `nghttp2_session_mem_recv2()` functions immediately return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`. To set this callback to :type:`nghttp2_session_callbacks`, use `nghttp2_session_callbacks_set_on_header_callback()`. .. warning:: Application should properly limit the total buffer size to store incoming header fields. Without it, peer may send large number of header fields or large header fields to cause out of memory in local endpoint. Due to how HPACK works, peer can do this effectively without using much memory on their own. .. type:: int (*nghttp2_on_header_callback2)(nghttp2_session *session, const nghttp2_frame *frame, nghttp2_rcbuf *name, nghttp2_rcbuf *value, uint8_t flags, void *user_data) Callback function invoked when a header name/value pair is received for the *frame*. The *name* is header name. The *value* is header value. The *flags* is bitwise OR of one or more of :type:`nghttp2_nv_flag`. This callback behaves like :type:`nghttp2_on_header_callback`, except that *name* and *value* are stored in reference counted buffer. If application wishes to keep these references without copying them, use `nghttp2_rcbuf_incref()` to increment their reference count. It is the application's responsibility to call `nghttp2_rcbuf_decref()` if they called `nghttp2_rcbuf_incref()` so as not to leak memory. If the *session* is created by `nghttp2_session_server_new3()` or `nghttp2_session_client_new3()`, the function to free memory is the one belongs to the mem parameter. As long as this free function alives, *name* and *value* can live after *session* was destroyed. .. type:: int (*nghttp2_on_invalid_header_callback)( nghttp2_session *session, const nghttp2_frame *frame, const uint8_t *name, size_t namelen, const uint8_t *value, size_t valuelen, uint8_t flags, void *user_data) Callback function invoked when an invalid header name/value pair is received for the *frame*. The parameter and behaviour are similar to :type:`nghttp2_on_header_callback`. The difference is that this callback is only invoked when an invalid header name/value pair is received which is treated as stream error if this callback returns :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` and :type:`nghttp2_on_invalid_header_callback2` is not set. Only invalid regular header field are passed to this callback. In other words, invalid pseudo header field is not passed to this callback.

To change connection level window size, specify 0 to *stream_id*. To increase window size, this function may submit WINDOW_UPDATE frame to transmission queue. The *flags* is currently ignored and should be :enum:`nghttp2_flag.NGHTTP2_FLAG_NONE`. This sounds similar to `nghttp2_submit_window_update()`, but there are 2 differences. The first difference is that this function takes the absolute value of window size to set, rather than the delta. To change the window size, this may be easier to use since the application just declares the intended window size, rather than calculating delta. The second difference is that `nghttp2_submit_window_update()` affects the received bytes count which has not acked yet. By the specification of `nghttp2_submit_window_update()`, to strictly increase the local window size, we have to submit delta including all received bytes count, which might not be desirable in some cases. On the other hand, this function does not affect the received bytes count. It just sets the local window size to the given value. This function returns 0 if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_INVALID_ARGUMENT` The *stream_id* is negative.

This directory contains the source files to be processed by Sphinx. The source file for API reference is generated using a script called ``mkapiref.py`` from the nghttp2 C source code. Generating API reference ------------------------ As described earlier, we use ``mkapiref.py`` to generate rst formatted text of API reference from C source code. The ``mkapiref.py`` is not so flexible and it requires that C source code is formatted in rather strict rules. To generate API reference, just run ``make html``. It runs ``mkapiref.py`` and then run Sphinx to build the entire document. The ``mkapiref.py`` reads C source code and searches the comment block starts with ``/**``. In other words, it only processes the comment block starting ``/**``. The comment block must end with ``*/``. The ``mkapiref.py`` requires that which type of the object this comment block refers to. To specify the type of the object, the next line must contain the so-called action keyword. Currently, the following action keywords are supported: ``@function``, ``@functypedef``, ``@enum``, ``@struct`` and ``@union``. The following sections describes each action keyword. @function ######### ``@function`` is used to refer to the function. The comment block is used for the document for the function. After the script sees the end of the comment block, it consumes the lines as the function declaration until the line which ends with ``;`` is encountered. In Sphinx doc, usually the function argument is formatted like ``*this*``. But in C, ``*`` is used for dereferencing a pointer and we must escape ``*`` with a back slash. To avoid this, we format the argument like ``|this|``. The ``mkapiref.py`` translates it with ``*this*``, as escaping ``*`` inside ``|`` and ``|`` as necessary. Note that this shadows the substitution feature of Sphinx. The example follows:: /** * @function * * Submits PING frame to the |session|. */ int nghttp2_submit_ping(nghttp2_session *session); @functypedef ############ ``@functypedef`` is used to refer to the typedef of the function pointer. The formatting rule is pretty much the same with ``@function``, but this outputs ``type`` domain, rather than ``function`` domain. The example follows:: /** * @functypedef * * Callback function invoked when |session| wants to send data to * remote peer. */ typedef nghttp2_ssize (*nghttp2_send_callback2) (nghttp2_session *session, const uint8_t *data, size_t length, int flags, void *user_data); @enum ##### ``@enum`` is used to refer to the enum. Currently, only enum typedefs are supported. The comment block is used for the document for the enum type itself. To document each values, put comment block starting with the line ``/**`` and ending with the ``*/`` just before the enum value. When the line starts with ``}`` is encountered, the ``mkapiref.py`` extracts strings next to ``}`` as the name of enum. At the time of this writing, Sphinx does not support enum type. So we use ``type`` domain for enum it self and ``macro`` domain for each value. To refer to the enum value, use ``:enum:`` pseudo role. The ``mkapiref.py`` replaces it with ``:macro:``. By doing this, when Sphinx will support enum officially, we can replace ``:enum:`` with the official role easily. The example follows:: /** * @enum * Error codes used in the nghttp2 library. */ typedef enum { /** * Invalid argument passed. */ NGHTTP2_ERR_INVALID_ARGUMENT = -501, /** * Zlib error. */ NGHTTP2_ERR_ZLIB = -502, } nghttp2_error; @struct ####### ``@struct`` is used to refer to the struct. Currently, only struct typedefs are supported. The comment block is used for the document for the struct type itself. To document each member, put comment block starting with the line ``/**`` and ending with the ``*/`` just before the member. When the line starts with ``}`` is encountered, the ``mkapiref.py`` extracts strings next to ``}`` as the name of struct. The block-less typedef is also supported. In this case, typedef declaration must be all in one line and the ``mkapiref.py`` uses last word as the name of struct. Some examples follow:: /** * @struct * The control frame header. */ typedef struct { /** * SPDY protocol version. */ uint16_t version; /** * The type of this control frame. */ uint16_t type; /** * The control frame flags. */ uint8_t flags; /** * The length field of this control frame. */ int32_t length; } nghttp2_ctrl_hd; /** * @struct * * The primary structure to hold the resources needed for a SPDY * session. The details of this structure is hidden from the public * API. */ typedef struct nghttp2_session nghttp2_session; @union ###### ``@union`` is used to refer to the union. Currently, ``@union`` is an alias of ``@struct``. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_submit_window_update.rst0000644000000000000000000000013215232371110021437 xustar0030 mtime=1785328200.992868013 30 atime=1785328201.291796023 30 ctime=1785328204.749120582 nghttp2-1.70.0/doc/nghttp2_submit_window_update.rst0000644000175100017510000000340115232371110022025 0ustar00runnerrunner nghttp2_submit_window_update ============================ Synopsis -------- *#include * .. function:: int nghttp2_submit_window_update(nghttp2_session *session, uint8_t flags, int32_t stream_id, int32_t window_size_increment) Submits WINDOW_UPDATE frame. The *flags* is currently ignored and should be :enum:`nghttp2_flag.NGHTTP2_FLAG_NONE`. The *stream_id* is the stream ID to send this WINDOW_UPDATE. To send connection level WINDOW_UPDATE, specify 0 to *stream_id*. If the *window_size_increment* is positive, the WINDOW_UPDATE with that value as window_size_increment is queued. If the *window_size_increment* is larger than the received bytes from the remote endpoint, the local window size is increased by that difference. If the sole purpose is to increase the local window size, consider to use `nghttp2_session_set_local_window_size()`. If the *window_size_increment* is negative, the local window size is decreased by -*window_size_increment*. If automatic WINDOW_UPDATE is enabled (`nghttp2_option_set_no_auto_window_update()`), and the library decided that the WINDOW_UPDATE should be submitted, then WINDOW_UPDATE is queued with the current received bytes count. If the sole purpose is to decrease the local window size, consider to use `nghttp2_session_set_local_window_size()`. If the *window_size_increment* is 0, the function does nothing and returns 0. This function returns 0 if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_FLOW_CONTROL` The local window size overflow or gets negative. :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_session_upgrade2.rst0000644000000000000000000000013215232371110020457 xustar0030 mtime=1785328200.991308726 30 atime=1785328201.249795498 30 ctime=1785328204.707040811 nghttp2-1.70.0/doc/nghttp2_session_upgrade2.rst0000644000175100017510000000404115232371110021046 0ustar00runnerrunner nghttp2_session_upgrade2 ======================== Synopsis -------- *#include * .. function:: int nghttp2_session_upgrade2(nghttp2_session *session, const uint8_t *settings_payload, size_t settings_payloadlen, int head_request, void *stream_user_data) Performs post-process of HTTP Upgrade request. This function can be called from both client and server, but the behavior is very different in each other. If called from client side, the *settings_payload* must be the value sent in ``HTTP2-Settings`` header field and must be decoded by base64url decoder. The *settings_payloadlen* is the length of *settings_payload*. The *settings_payload* is unpacked and its setting values will be submitted using `nghttp2_submit_settings()`. This means that the client application code does not need to submit SETTINGS by itself. The stream with stream ID=1 is opened and the *stream_user_data* is used for its stream_user_data. The opened stream becomes half-closed (local) state. If called from server side, the *settings_payload* must be the value received in ``HTTP2-Settings`` header field and must be decoded by base64url decoder. The *settings_payloadlen* is the length of *settings_payload*. It is treated as if the SETTINGS frame with that payload is received. Thus, callback functions for the reception of SETTINGS frame will be invoked. The stream with stream ID=1 is opened. The *stream_user_data* is ignored. The opened stream becomes half-closed (remote). If the request method is HEAD, pass nonzero value to *head_request*. Otherwise, pass 0. This function returns 0 if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. :enum:`nghttp2_error.NGHTTP2_ERR_INVALID_ARGUMENT` The *settings_payload* is badly formed. :enum:`nghttp2_error.NGHTTP2_ERR_PROTO` The stream ID 1 is already used or closed; or is not available. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_session_consume.rst0000644000000000000000000000013215232371110020417 xustar0030 mtime=1785328200.989399635 30 atime=1785328201.189927953 30 ctime=1785328204.649014165 nghttp2-1.70.0/doc/nghttp2_session_consume.rst0000644000175100017510000000205115232371110021005 0ustar00runnerrunner nghttp2_session_consume ======================= Synopsis -------- *#include * .. function:: int nghttp2_session_consume(nghttp2_session *session, int32_t stream_id, size_t size) Tells the *session* that *size* bytes for a stream denoted by *stream_id* were consumed by application and are ready to WINDOW_UPDATE.

DESCRIPTION ----------- benchmarking tool for HTTP/2 server .. describe:: Specify URI to access. Multiple URIs can be specified. URIs are used in this order for each client. All URIs are used, then first URI is used and then 2nd URI, and so on. The scheme, host and port in the subsequent URIs, if present, are ignored. Those in the first URI are used solely. Definition of a base URI overrides all scheme, host or port values. OPTIONS ------- .. option:: -n, --requests= Number of requests across all clients. If it is used with :option:`--timing-script-file` option, this option specifies the number of requests each client performs rather than the number of requests across all clients. This option is ignored if timing-based benchmarking is enabled (see :option:`--duration` option). Default: ``1`` .. option:: -c, --clients= Number of concurrent clients. With :option:`-r` option, this specifies the maximum number of connections to be made. Default: ``1`` .. option:: -t, --threads= Number of native threads. Default: ``1`` .. option:: -i, --input-file= Path of a file with multiple URIs are separated by EOLs. This option will disable URIs getting from command-line. If '-' is given as , URIs will be read from stdin. URIs are used in this order for each client. All URIs are used, then first URI is used and then 2nd URI, and so on. The scheme, host and port in the subsequent URIs, if present, are ignored. Those in the first URI are used solely. Definition of a base URI overrides all scheme, host or port values. .. option:: -m, --max-concurrent-streams= Max concurrent streams to issue per session. When http/1.1 is used, this specifies the number of HTTP pipelining requests in-flight. Default: ``1`` .. option:: -f, --max-frame-size= Maximum frame size that the local endpoint is willing to receive. Default: ``16K`` .. option:: -w, --window-bits= Sets the stream level initial window size to (2\*\*)-1. For QUIC, is capped to 26 (roughly 64MiB). It defaults to 24 (16MiB) for QUIC, and 30 for other protocols. .. option:: -W, --connection-window-bits= Sets the connection level initial window size to (2\*\*)-1. Default: ``30`` .. option:: -H, --header=
Add/Override a header to the requests. .. option:: --ciphers= Set allowed cipher list for TLSv1.2 or earlier. The format of the string is described in OpenSSL ciphers(1). Default: ``ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384`` .. option:: --tls13-ciphers= Set allowed cipher list for TLSv1.3. The format of the string is described in OpenSSL ciphers(1). Default: ``TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_CCM_SHA256`` .. option:: -p, --no-tls-proto= Specify ALPN identifier of the protocol to be used when accessing http URI without SSL/TLS. Available protocols: h2c and http/1.1 Default: ``h2c`` .. option:: -d, --data= Post FILE to server. The request method is changed to POST. For http/1.1 connection, if :option:`-d` is used, the maximum number of in-flight pipelined requests is set to 1. .. option:: -r, --rate= Specifies the fixed rate at which connections are created. The rate must be a positive integer, representing the number of connections to be made per rate period. The maximum number of connections to be made is given in :option:`-c` option. This rate will be distributed among threads as evenly as possible. For example, with :option:`-t`\2 and :option:`-r`\4, each thread gets 2 connections per period. When the rate is 0, the program will run as it normally does, creating connections at whatever variable rate it wants. The default value for this option is 0. :option:`-r` and :option:`\-D` are mutually exclusive. .. option:: --rate-period= Specifies the time period between creating connections. The period must be a positive number, representing the length of the period in time. This option is ignored if the rate option is not used. The default value for this option is 1s. .. option:: -D, --duration= Specifies the main duration for the measurements in case of timing-based benchmarking. :option:`-D` and :option:`\-r` are mutually exclusive. .. option:: --warm-up-time= Specifies the time period before starting the actual measurements, in case of timing-based benchmarking. Needs to provided along with :option:`-D` option. .. option:: -T, --connection-active-timeout= Specifies the maximum time that h2load is willing to keep a connection open, regardless of the activity on said connection. must be a positive integer, specifying the amount of time to wait. When no timeout value is set (either active or inactive), h2load will keep a connection open indefinitely, waiting for a response. .. option:: -N, --connection-inactivity-timeout= Specifies the amount of time that h2load is willing to wait to see activity on a given connection. must be a positive integer, specifying the amount of time to wait. When no timeout value is set (either active or inactive), h2load will keep a connection open indefinitely, waiting for a response. .. option:: --timing-script-file= Path of a file containing one or more lines separated by EOLs. Each script line is composed of two tab-separated fields. The first field represents the time offset from the start of execution, expressed as a positive value of milliseconds with microsecond resolution. The second field represents the URI. This option will disable URIs getting from command-line. If '-' is given as , script lines will be read from stdin. Script lines are used in order for each client. If :option:`-n` is given, it must be less than or equal to the number of script lines, larger values are clamped to the number of script lines. If :option:`-n` is not given, the number of requests will default to the number of script lines. The scheme, host and port defined in the first URI are used solely. Values contained in other URIs, if present, are ignored. Definition of a base URI overrides all scheme, host or port values. :option:`--timing-script-file` and :option:`\--rps` are mutually exclusive. .. option:: -B, --base-uri=(|unix:) Specify URI from which the scheme, host and port will be used for all requests. The base URI overrides all values defined either at the command line or inside input files. If argument starts with "unix:", then the rest of the argument will be treated as UNIX domain socket path. The connection is made through that path instead of TCP. In this case, scheme is inferred from the first URI appeared in the command line or inside input files as usual. .. option:: --alpn-list= Comma delimited list of ALPN protocol identifier sorted in the order of preference. That means most desirable protocol comes first. The parameter must be delimited by a single comma only and any white spaces are treated as a part of protocol string. Default: ``h2,http/1.1`` .. option:: --h1 Short hand for :option:`--alpn-list`\=http/1.1 :option:`--no-tls-proto`\=http/1.1, which effectively force http/1.1 for both http and https URI. .. option:: --h3 Short hand for :option:`--alpn-list`\=h3, which effectively forces HTTP/3. .. option:: --header-table-size= Specify decoder header table size. Default: ``4K`` .. option:: --encoder-header-table-size= Specify encoder header table size. The decoder (server) specifies the maximum dynamic table size it accepts. Then the negotiated dynamic table size is the minimum of this option value and the value which server specified. Default: ``4K`` .. option:: --log-file= Write per-request information to a file as tab-separated columns: start time as microseconds since epoch; HTTP status code; microseconds until end of response. More columns may be added later. Rows are ordered by end-of- response time when using one worker thread, but may appear slightly out of order with multiple threads due to buffering. Status code is -1 for failed streams. .. option:: --qlog-file-base= Enable qlog output and specify base file name for qlogs. Qlog is emitted for each connection. For a given base name "base", each output file name becomes "base.M.N.sqlog" where M is worker ID and N is client ID (e.g. "base.0.3.sqlog"). Only effective in QUIC runs. .. option:: --connect-to=[:] Host and port to connect instead of using the authority in . .. option:: --rps= Specify request per second for each client. :option:`--rps` and :option:`--timing-script-file` are mutually exclusive. .. option:: --groups= Specify the supported groups. Default: ``X25519:P-256:P-384:P-521`` .. option:: --no-udp-gso Disable UDP GSO. .. option:: --max-udp-payload-size= Specify the maximum outgoing UDP datagram payload size. .. option:: --ktls Enable ktls. .. option:: --sni= Send in TLS SNI, overriding the host name specified in URI. .. option:: --histogram Plot histogram for performance statistics. .. option:: --tls-session-file= Read TLS session from , and set it to all TLS connections to perform the session resumption. It is also used to store the new TLS session. At most one session is written to the given file. .. option:: --output-file= Write the measurement results to in JSON format. This basically includes all numbers reported to the normal output. In addition, for performance measurements, all raw samples are included. .. option:: -v, --verbose Output debug information. .. option:: --version Display version information and exit. .. option:: -h, --help Display this help and exit. The argument is an integer and an optional unit (e.g., 10K is 10 * 1024). Units are K, M and G (powers of 1024). The argument is an integer and an optional unit (e.g., 1s is 1 second and 500ms is 500 milliseconds). Units are h, m, s or ms (hours, minutes, seconds and milliseconds, respectively). If a unit is omitted, a second is used as unit. .. _h2load-1-output: OUTPUT ------ REQUEST METRICS ~~~~~~~~~~~~~~~ requests total The total number of requests h2load was instructed to make. started The number of requests initiated by the tool. done The number of requests that reached completion. succeeded Requests resulting in an HTTP 2xx or 3xx status code. failed The total number of failed requests. This includes both ``errored`` requests and requests that completed with a non-2xx/3xx status code. errored A subset of ``failed`` where the requests failed due to network-level issues (e.g., TCP resets, ``RST_STREAM``) rather than HTTP status codes. timeout A subset of ``errored`` where the connection timed out before completion. status codes The specific count of received HTTP status codes categorized by class (2xx, 3xx, 4xx, 5xx). TRAFFIC METRICS ~~~~~~~~~~~~~~~ traffic total Total application data bytes received "on the wire" (decrypted if using TLS). headers Total bytes used for response headers (pre-decompression). space savings Header compression efficiency, calculated as: (1 - headers / decompressed_headers) * 100 where ``headers`` is the compressed size and ``decompressed_headers`` is the size after decompression. data Total bytes received in response bodies. PERFORMANCE STATISTICS ~~~~~~~~~~~~~~~~~~~~~~ Metric Definitions request The duration from sending the first byte of a request to receiving the last byte of the response. connect The time taken to establish a connection, including TLS handshakes. TTFB The duration until the first byte of application data is received from the server (decrypted if using TLS). req/s The requests per second measured individually across all clients. min RTT The minimum RTT (QUIC). smoothed RTT The smoothed RTT (QUIC). packets sent The number of packets sent (QUIC). packets recv The number of packets received (QUIC). packets lost The number of packets declared lost (QUIC). GRO packets The number of packets received in a single recvmsg call (QUIC). Distribution Fields min / max The absolute minimum and maximum values recorded. median The 50th percentile value. p95 / p99 The 95th and 99th percentiles, indicating tail performance. mean The arithmetic average of all samples. sd The standard deviation (measure of data dispersion). +/- sd The percentage of successful samples falling within one standard deviation of the mean (mean +/- sd). FLOW CONTROL ------------ h2load sets large flow control window by default, and effectively disables flow control to avoid under utilization of server performance. To set smaller flow control window, use :option:`-w` and :option:`-W` options. For example, use ``-w16 -W16`` to set default window size described in HTTP/2 protocol specification.

Note that HTTP/2 maintains connection and stream level flow control windows independently. This function returns 0 if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. :enum:`nghttp2_error.NGHTTP2_ERR_INVALID_ARGUMENT` The *stream_id* is 0. :enum:`nghttp2_error.NGHTTP2_ERR_INVALID_STATE` Automatic WINDOW_UPDATE is not disabled. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_option_set_no_auto_window_update.rst0000644000000000000000000000013115232371110024042 xustar0029 mtime=1785328200.98697425 30 atime=1785328201.103793674 30 ctime=1785328204.564837798 nghttp2-1.70.0/doc/nghttp2_option_set_no_auto_window_update.rst0000644000175100017510000000116215232371110024433 0ustar00runnerrunner nghttp2_option_set_no_auto_window_update ======================================== Synopsis -------- *#include * .. function:: void nghttp2_option_set_no_auto_window_update(nghttp2_option *option, int val) This option prevents the library from sending WINDOW_UPDATE for a connection automatically. If this option is set to nonzero, the library won't send WINDOW_UPDATE for DATA until application calls `nghttp2_session_consume()` to indicate the consumed amount of data. Don't use `nghttp2_submit_window_update()` for this purpose.

This function performs decompression. For each successful emission of header name/value pair, :enum:`nghttp2_hd_inflate_flag.NGHTTP2_HD_INFLATE_EMIT` is set in *\*inflate_flags* and name/value pair is assigned to the *nv_out* and the function returns. The caller must not free the members of *nv_out*. The *nv_out* may include pointers to the memory region in the *in*. The caller must retain the *in* while the *nv_out* is used. The application should call this function repeatedly until the ``(*inflate_flags) & NGHTTP2_HD_INFLATE_FINAL`` is nonzero and return value is non-negative. If that happens, all given input data (*inlen* bytes) are processed successfully. Then the application must call `nghttp2_hd_inflate_end_headers()` to prepare for the next header block input. In other words, if *in_final* is nonzero, and this function returns *inlen*, you can assert that :enum:`nghttp2_hd_inflate_final.NGHTTP2_HD_INFLATE_FINAL` is set in *\*inflate_flags*.

This function is only usable for server. If this function is called with client side session, this function returns :enum:`nghttp2_error.NGHTTP2_ERR_INVALID_STATE`. To gracefully shutdown HTTP/2 session, server should call this function to send GOAWAY with last_stream_id (1u << 31) - 1. And after some delay (e.g., 1 RTT), send another GOAWAY with the stream ID that the server has some processing using `nghttp2_submit_goaway()`. See also `nghttp2_session_get_last_proc_stream_id()`. Unlike `nghttp2_submit_goaway()`, this function just sends GOAWAY and does nothing more. This is a mere indication to the client that session shutdown is imminent. The application should call `nghttp2_submit_goaway()` with appropriate last_stream_id after this call. If one or more GOAWAY frame have been already sent by either `nghttp2_submit_goaway()` or `nghttp2_session_terminate_session()`, this function has no effect.

The library handles the CONTINUATION frame internally and it correctly sets END_HEADERS to the last sequence of the PUSH_PROMISE or CONTINUATION frame. If the *stream_id* is -1, this frame is assumed as request (i.e., request HEADERS frame which opens new stream). In this case, the assigned stream ID will be returned. Otherwise, specify stream ID in *stream_id*. The *pri_spec* is ignored. The *nva* is an array of name/value pair :type:`nghttp2_nv` with *nvlen* elements.

The *stream_user_data* is a pointer to an arbitrary data which is associated to the stream this frame will open. Therefore it is only used if this frame opens streams, in other words, it changes stream state from idle or reserved to open.

Use `nghttp2_hd_inflate_hd3()` instead. Inflates name/value block stored in *in* with length *inlen*. This function performs decompression. For each successful emission of header name/value pair, :enum:`nghttp2_hd_inflate_flag.NGHTTP2_HD_INFLATE_EMIT` is set in *\*inflate_flags* and name/value pair is assigned to the *nv_out* and the function returns. The caller must not free the members of *nv_out*. The *nv_out* may include pointers to the memory region in the *in*. The caller must retain the *in* while the *nv_out* is used. The application should call this function repeatedly until the ``(*inflate_flags) & NGHTTP2_HD_INFLATE_FINAL`` is nonzero and return value is non-negative. If that happens, all given input data (*inlen* bytes) are processed successfully. Then the application must call `nghttp2_hd_inflate_end_headers()` to prepare for the next header block input.

The caller can feed complete compressed header block. It also can feed it in several chunks. The caller must set *in_final* to nonzero if the given input is the last block of the compressed header.

[URI]... .SH DESCRIPTION .sp benchmarking tool for HTTP/2 server .INDENT 0.0 .TP .B Specify URI to access. Multiple URIs can be specified. URIs are used in this order for each client. All URIs are used, then first URI is used and then 2nd URI, and so on. The scheme, host and port in the subsequent URIs, if present, are ignored. Those in the first URI are used solely. Definition of a base URI overrides all scheme, host or port values. .UNINDENT .SH OPTIONS .INDENT 0.0 .TP .B \-n, \-\-requests= Number of requests across all clients. If it is used with \fB\-\-timing\-script\-file\fP option, this option specifies the number of requests each client performs rather than the number of requests across all clients. This option is ignored if timing\-based benchmarking is enabled (see \fB\-\-duration\fP option). .sp Default: \fB1\fP .UNINDENT .INDENT 0.0 .TP .B \-c, \-\-clients= Number of concurrent clients. With \fB\-r\fP option, this specifies the maximum number of connections to be made. .sp Default: \fB1\fP .UNINDENT .INDENT 0.0 .TP .B \-t, \-\-threads= Number of native threads. .sp Default: \fB1\fP .UNINDENT .INDENT 0.0 .TP .B \-i, \-\-input\-file= Path of a file with multiple URIs are separated by EOLs. This option will disable URIs getting from command\-line. If \(aq\-\(aq is given as , URIs will be read from stdin. URIs are used in this order for each client. All URIs are used, then first URI is used and then 2nd URI, and so on. The scheme, host and port in the subsequent URIs, if present, are ignored. Those in the first URI are used solely. Definition of a base URI overrides all scheme, host or port values. .UNINDENT .INDENT 0.0 .TP .B \-m, \-\-max\-concurrent\-streams= Max concurrent streams to issue per session. When http/1.1 is used, this specifies the number of HTTP pipelining requests in\-flight. .sp Default: \fB1\fP .UNINDENT .INDENT 0.0 .TP .B \-f, \-\-max\-frame\-size= Maximum frame size that the local endpoint is willing to receive. .sp Default: \fB16K\fP .UNINDENT .INDENT 0.0 .TP .B \-w, \-\-window\-bits= Sets the stream level initial window size to (2**)\-1. For QUIC, is capped to 26 (roughly 64MiB). It defaults to 24 (16MiB) for QUIC, and 30 for other protocols. .UNINDENT .INDENT 0.0 .TP .B \-W, \-\-connection\-window\-bits= Sets the connection level initial window size to (2**)\-1. .sp Default: \fB30\fP .UNINDENT .INDENT 0.0 .TP .B \-H, \-\-header=
Add/Override a header to the requests. .UNINDENT .INDENT 0.0 .TP .B \-\-ciphers= Set allowed cipher list for TLSv1.2 or earlier. The format of the string is described in OpenSSL ciphers(1). .sp Default: \fBECDHE\-ECDSA\-AES128\-GCM\-SHA256:ECDHE\-RSA\-AES128\-GCM\-SHA256:ECDHE\-ECDSA\-AES256\-GCM\-SHA384:ECDHE\-RSA\-AES256\-GCM\-SHA384:ECDHE\-ECDSA\-CHACHA20\-POLY1305:ECDHE\-RSA\-CHACHA20\-POLY1305:DHE\-RSA\-AES128\-GCM\-SHA256:DHE\-RSA\-AES256\-GCM\-SHA384\fP .UNINDENT .INDENT 0.0 .TP .B \-\-tls13\-ciphers= Set allowed cipher list for TLSv1.3. The format of the string is described in OpenSSL ciphers(1). .sp Default: \fBTLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_CCM_SHA256\fP .UNINDENT .INDENT 0.0 .TP .B \-p, \-\-no\-tls\-proto= Specify ALPN identifier of the protocol to be used when accessing http URI without SSL/TLS. Available protocols: h2c and http/1.1 .sp Default: \fBh2c\fP .UNINDENT .INDENT 0.0 .TP .B \-d, \-\-data= Post FILE to server. The request method is changed to POST. For http/1.1 connection, if \fB\-d\fP is used, the maximum number of in\-flight pipelined requests is set to 1. .UNINDENT .INDENT 0.0 .TP .B \-r, \-\-rate= Specifies the fixed rate at which connections are created. The rate must be a positive integer, representing the number of connections to be made per rate period. The maximum number of connections to be made is given in \fB\-c\fP option. This rate will be distributed among threads as evenly as possible. For example, with \fB\-t\fP2 and \fB\-r\fP4, each thread gets 2 connections per period. When the rate is 0, the program will run as it normally does, creating connections at whatever variable rate it wants. The default value for this option is 0. \fB\-r\fP and \fB\-D\fP are mutually exclusive. .UNINDENT .INDENT 0.0 .TP .B \-\-rate\-period= Specifies the time period between creating connections. The period must be a positive number, representing the length of the period in time. This option is ignored if the rate option is not used. The default value for this option is 1s. .UNINDENT .INDENT 0.0 .TP .B \-D, \-\-duration= Specifies the main duration for the measurements in case of timing\-based benchmarking. \fB\-D\fP and \fB\-r\fP are mutually exclusive. .UNINDENT .INDENT 0.0 .TP .B \-\-warm\-up\-time= Specifies the time period before starting the actual measurements, in case of timing\-based benchmarking. Needs to provided along with \fB\-D\fP option. .UNINDENT .INDENT 0.0 .TP .B \-T, \-\-connection\-active\-timeout= Specifies the maximum time that h2load is willing to keep a connection open, regardless of the activity on said connection. must be a positive integer, specifying the amount of time to wait. When no timeout value is set (either active or inactive), h2load will keep a connection open indefinitely, waiting for a response. .UNINDENT .INDENT 0.0 .TP .B \-N, \-\-connection\-inactivity\-timeout= Specifies the amount of time that h2load is willing to wait to see activity on a given connection. must be a positive integer, specifying the amount of time to wait. When no timeout value is set (either active or inactive), h2load will keep a connection open indefinitely, waiting for a response. .UNINDENT .INDENT 0.0 .TP .B \-\-timing\-script\-file= Path of a file containing one or more lines separated by EOLs. Each script line is composed of two tab\-separated fields. The first field represents the time offset from the start of execution, expressed as a positive value of milliseconds with microsecond resolution. The second field represents the URI. This option will disable URIs getting from command\-line. If \(aq\-\(aq is given as , script lines will be read from stdin. Script lines are used in order for each client. If \fB\-n\fP is given, it must be less than or equal to the number of script lines, larger values are clamped to the number of script lines. If \fB\-n\fP is not given, the number of requests will default to the number of script lines. The scheme, host and port defined in the first URI are used solely. Values contained in other URIs, if present, are ignored. Definition of a base URI overrides all scheme, host or port values. \fB\-\-timing\-script\-file\fP and \fB\-\-rps\fP are mutually exclusive. .UNINDENT .INDENT 0.0 .TP .B \-B, \-\-base\-uri=(|unix:) Specify URI from which the scheme, host and port will be used for all requests. The base URI overrides all values defined either at the command line or inside input files. If argument starts with \(dqunix:\(dq, then the rest of the argument will be treated as UNIX domain socket path. The connection is made through that path instead of TCP. In this case, scheme is inferred from the first URI appeared in the command line or inside input files as usual. .UNINDENT .INDENT 0.0 .TP .B \-\-alpn\-list= Comma delimited list of ALPN protocol identifier sorted in the order of preference. That means most desirable protocol comes first. The parameter must be delimited by a single comma only and any white spaces are treated as a part of protocol string. .sp Default: \fBh2,http/1.1\fP .UNINDENT .INDENT 0.0 .TP .B \-\-h1 Short hand for \fB\-\-alpn\-list\fP=http/1.1 \fB\-\-no\-tls\-proto\fP=http/1.1, which effectively force http/1.1 for both http and https URI. .UNINDENT .INDENT 0.0 .TP .B \-\-h3 Short hand for \fB\-\-alpn\-list\fP=h3, which effectively forces HTTP/3. .UNINDENT .INDENT 0.0 .TP .B \-\-header\-table\-size= Specify decoder header table size. .sp Default: \fB4K\fP .UNINDENT .INDENT 0.0 .TP .B \-\-encoder\-header\-table\-size= Specify encoder header table size. The decoder (server) specifies the maximum dynamic table size it accepts. Then the negotiated dynamic table size is the minimum of this option value and the value which server specified. .sp Default: \fB4K\fP .UNINDENT .INDENT 0.0 .TP .B \-\-log\-file= Write per\-request information to a file as tab\-separated columns: start time as microseconds since epoch; HTTP status code; microseconds until end of response. More columns may be added later. Rows are ordered by end\-of\- response time when using one worker thread, but may appear slightly out of order with multiple threads due to buffering. Status code is \-1 for failed streams. .UNINDENT .INDENT 0.0 .TP .B \-\-qlog\-file\-base= Enable qlog output and specify base file name for qlogs. Qlog is emitted for each connection. For a given base name \(dqbase\(dq, each output file name becomes \(dqbase.M.N.sqlog\(dq where M is worker ID and N is client ID (e.g. \(dqbase.0.3.sqlog\(dq). Only effective in QUIC runs. .UNINDENT .INDENT 0.0 .TP .B \-\-connect\-to=[:] Host and port to connect instead of using the authority in . .UNINDENT .INDENT 0.0 .TP .B \-\-rps= Specify request per second for each client. \fB\-\-rps\fP and \fB\-\-timing\-script\-file\fP are mutually exclusive. .UNINDENT .INDENT 0.0 .TP .B \-\-groups= Specify the supported groups. .sp Default: \fBX25519:P\-256:P\-384:P\-521\fP .UNINDENT .INDENT 0.0 .TP .B \-\-no\-udp\-gso Disable UDP GSO. .UNINDENT .INDENT 0.0 .TP .B \-\-max\-udp\-payload\-size= Specify the maximum outgoing UDP datagram payload size. .UNINDENT .INDENT 0.0 .TP .B \-\-ktls Enable ktls. .UNINDENT .INDENT 0.0 .TP .B \-\-sni= Send in TLS SNI, overriding the host name specified in URI. .UNINDENT .INDENT 0.0 .TP .B \-\-histogram Plot histogram for performance statistics. .UNINDENT .INDENT 0.0 .TP .B \-\-tls\-session\-file= Read TLS session from , and set it to all TLS connections to perform the session resumption. It is also used to store the new TLS session. At most one session is written to the given file. .UNINDENT .INDENT 0.0 .TP .B \-\-output\-file= Write the measurement results to in JSON format. This basically includes all numbers reported to the normal output. In addition, for performance measurements, all raw samples are included. .UNINDENT .INDENT 0.0 .TP .B \-v, \-\-verbose Output debug information. .UNINDENT .INDENT 0.0 .TP .B \-\-version Display version information and exit. .UNINDENT .INDENT 0.0 .TP .B \-h, \-\-help Display this help and exit. .UNINDENT .sp The argument is an integer and an optional unit (e.g., 10K is 10 * 1024). Units are K, M and G (powers of 1024). .sp The argument is an integer and an optional unit (e.g., 1s is 1 second and 500ms is 500 milliseconds). Units are h, m, s or ms (hours, minutes, seconds and milliseconds, respectively). If a unit is omitted, a second is used as unit. .SH OUTPUT .SS REQUEST METRICS .INDENT 0.0 .TP .B requests .INDENT 7.0 .TP .B total The total number of requests h2load was instructed to make. .TP .B started The number of requests initiated by the tool. .TP .B done The number of requests that reached completion. .TP .B succeeded Requests resulting in an HTTP 2xx or 3xx status code. .TP .B failed The total number of failed requests. This includes both \fBerrored\fP requests and requests that completed with a non\-2xx/3xx status code. .TP .B errored A subset of \fBfailed\fP where the requests failed due to network\-level issues (e.g., TCP resets, \fBRST_STREAM\fP) rather than HTTP status codes. .TP .B timeout A subset of \fBerrored\fP where the connection timed out before completion. .UNINDENT .TP .B status codes The specific count of received HTTP status codes categorized by class (2xx, 3xx, 4xx, 5xx). .UNINDENT .SS TRAFFIC METRICS .INDENT 0.0 .TP .B traffic .INDENT 7.0 .TP .B total Total application data bytes received \(dqon the wire\(dq (decrypted if using TLS). .TP .B headers Total bytes used for response headers (pre\-decompression). .INDENT 7.0 .TP .B space savings Header compression efficiency, calculated as: .sp (1 \- headers / decompressed_headers) * 100 .sp where \fBheaders\fP is the compressed size and \fBdecompressed_headers\fP is the size after decompression. .UNINDENT .TP .B data Total bytes received in response bodies. .UNINDENT .UNINDENT .SS PERFORMANCE STATISTICS .INDENT 0.0 .TP .B Metric Definitions .INDENT 7.0 .TP .B request The duration from sending the first byte of a request to receiving the last byte of the response. .TP .B connect The time taken to establish a connection, including TLS handshakes. .TP .B TTFB The duration until the first byte of application data is received from the server (decrypted if using TLS). .TP .B req/s The requests per second measured individually across all clients. .TP .B min RTT The minimum RTT (QUIC). .TP .B smoothed RTT The smoothed RTT (QUIC). .TP .B packets sent The number of packets sent (QUIC). .TP .B packets recv The number of packets received (QUIC). .TP .B packets lost The number of packets declared lost (QUIC). .TP .B GRO packets The number of packets received in a single recvmsg call (QUIC). .UNINDENT .TP .B Distribution Fields .INDENT 7.0 .TP .B min / max The absolute minimum and maximum values recorded. .TP .B median The 50th percentile value. .TP .B p95 / p99 The 95th and 99th percentiles, indicating tail performance. .TP .B mean The arithmetic average of all samples. .TP .B sd The standard deviation (measure of data dispersion). .TP .B +/\- sd The percentage of successful samples falling within one standard deviation of the mean (mean +/\- sd). .UNINDENT .UNINDENT .SH FLOW CONTROL .sp h2load sets large flow control window by default, and effectively disables flow control to avoid under utilization of server performance. To set smaller flow control window, use \fB\-w\fP and \fB\-W\fP options. For example, use \fB\-w16 \-W16\fP to set default window size described in HTTP/2 protocol specification. .SH SEE ALSO .sp \fBnghttp(1)\fP, \fBnghttpd(1)\fP, \fBnghttpx(1)\fP .SH Author Tatsuhiro Tsujikawa .SH Copyright 2012, 2015, 2016, Tatsuhiro Tsujikawa .\" End of generated man page. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_session_server_new.rst0000644000000000000000000000013115232371110021124 xustar0030 mtime=1785328200.990843219 30 atime=1785328201.235795323 29 ctime=1785328204.69285329 nghttp2-1.70.0/doc/nghttp2_session_server_new.rst0000644000175100017510000000175215232371110021522 0ustar00runnerrunner nghttp2_session_server_new ========================== Synopsis -------- *#include * .. function:: int nghttp2_session_server_new(nghttp2_session **session_ptr, const nghttp2_session_callbacks *callbacks, void *user_data) Initializes *\*session_ptr* for server use.

It will call callback functions set by applications while processing input. The output of nghttp2 is just byte string. An application is responsible to send these output to the remote peer. The callback functions may be called while producing output. Not doing I/O makes embedding nghttp2 library in the existing code base very easy. Usually, the existing applications have its own I/O event loops. It is very hard to use nghttp2 in that situation if nghttp2 does its own I/O. It also makes light weight language wrapper for nghttp2 easy with the same reason. The down side is that an application author has to write more code to write complete application using nghttp2. This is especially true for simple "toy" application. For the real applications, however, this is not the case. This is because you probably want to support HTTP/1 which nghttp2 does not provide, and to do that, you will need to write your own HTTP/1 stack or use existing third-party library, and bind them together with nghttp2 and I/O event loop. In this point, not performing I/O in nghttp2 has more point than doing it. The primary object that an application uses is :type:`nghttp2_session` object, which is opaque struct and its details are hidden in order to ensure the upgrading its internal architecture without breaking the backward compatibility. An application can set callbacks to :type:`nghttp2_session` object through the dedicated object and functions, and it also interacts with it via many API function calls. An application can create as many :type:`nghttp2_session` object as it wants. But single :type:`nghttp2_session` object must be used by a single thread at the same time. This is not so hard to enforce since most event-based architecture applications use is single thread per core, and handling one connection I/O is done by single thread. To feed input to :type:`nghttp2_session` object, one can use `nghttp2_session_recv()` or `nghttp2_session_mem_recv2()` functions. They behave similarly, and the difference is that `nghttp2_session_recv()` will use :type:`nghttp2_read_callback` to get input. On the other hand, `nghttp2_session_mem_recv2()` will take input as its parameter. If in doubt, use `nghttp2_session_mem_recv2()` since it is simpler, and could be faster since it avoids calling callback function. To get output from :type:`nghttp2_session` object, one can use `nghttp2_session_send()` or `nghttp2_session_mem_send2()`. The difference between them is that the former uses :type:`nghttp2_send_callback` to pass output to an application. On the other hand, the latter returns the output to the caller. If in doubt, use `nghttp2_session_mem_send2()` since it is simpler. But `nghttp2_session_send()` might be easier to use if the output buffer an application has is fixed sized. In general, an application should call `nghttp2_session_mem_send2()` when it gets input from underlying connection. Since there is great chance to get something pushed into transmission queue while the call of `nghttp2_session_mem_send2()`, it is recommended to call `nghttp2_session_mem_recv2()` after `nghttp2_session_mem_send2()`. There is a question when we are safe to close HTTP/2 session without waiting for the closure of underlying connection. We offer 2 API calls for this: `nghttp2_session_want_read()` and `nghttp2_session_want_write()`. If they both return 0, application can destroy :type:`nghttp2_session`, and then close the underlying connection. But make sure that the buffered output has been transmitted to the peer before closing the connection when `nghttp2_session_mem_send2()` is used, since `nghttp2_session_want_write()` does not take into account the transmission of the buffered data outside of :type:`nghttp2_session`. Includes -------- To use the public APIs, include ``nghttp2/nghttp2.h``:: #include The header files are also available online: :doc:`nghttp2.h` and :doc:`nghttp2ver.h`. Remarks ------- Do not call `nghttp2_session_send()`, `nghttp2_session_mem_send2()`, `nghttp2_session_recv()` or `nghttp2_session_mem_recv2()` from the nghttp2 callback functions directly or indirectly. It will lead to the crash. You can submit requests or frames in the callbacks then call these functions outside the callbacks. `nghttp2_session_send()` and `nghttp2_session_mem_send2()` send first 24 bytes of client magic string (MAGIC) (:macro:`NGHTTP2_CLIENT_MAGIC`) on client configuration. The applications are responsible to send SETTINGS frame as part of connection preface using `nghttp2_submit_settings()`. Similarly, `nghttp2_session_recv()` and `nghttp2_session_mem_recv2()` consume MAGIC on server configuration unless `nghttp2_option_set_no_recv_client_magic()` is used with nonzero option value. .. _http-messaging: HTTP Messaging -------------- By default, nghttp2 library checks HTTP messaging rules described in `HTTP/2 specification, section 8 `_. Everything described in that section is not validated however. We briefly describe what the library does in this area. In the following description, without loss of generality we omit CONTINUATION frame since they must follow HEADERS frame and are processed atomically. In other words, they are just one big HEADERS frame. To disable these validations, use `nghttp2_option_set_no_http_messaging()`. Please note that disabling this feature does not change the fundamental client and server model of HTTP. That is, even if the validation is disabled, only client can send requests. For HTTP request, including those carried by PUSH_PROMISE, HTTP message starts with one HEADERS frame containing request headers. It is followed by zero or more DATA frames containing request body, which is followed by zero or one HEADERS containing trailer headers. The request headers must include ":scheme", ":method" and ":path" pseudo header fields unless ":method" is not "CONNECT". ":authority" is optional, but nghttp2 requires either ":authority" or "Host" header field must be present. If ":method" is "CONNECT", the request headers must include ":method" and ":authority" and must omit ":scheme" and ":path". For HTTP response, HTTP message starts with zero or more HEADERS frames containing non-final response (status code 1xx). They are followed by one HEADERS frame containing final response headers (non-1xx). It is followed by zero or more DATA frames containing response body, which is followed by zero or one HEADERS containing trailer headers. The non-final and final response headers must contain ":status" pseudo header field containing 3 digits only. All request and response headers must include exactly one valid value for each pseudo header field. Additionally nghttp2 requires all request headers must not include more than one "Host" header field. HTTP/2 prohibits connection-specific header fields. The following header fields must not appear: "Connection", "Keep-Alive", "Proxy-Connection", "Transfer-Encoding" and "Upgrade". Additionally, "TE" header field must not include any value other than "trailers". Each header field name and value must obey the field-name and field-value production rules described in `RFC 7230, section 3.2. `_. Additionally, all field name must be lower cased. The invalid header fields are treated as stream error, and that stream is reset. If application wants to treat these headers in their own way, use `nghttp2_on_invalid_header_callback `_. For "http" or "https" URIs, ":path" pseudo header fields must start with "/". The only exception is OPTIONS request, in that case, "*" is allowed in ":path" pseudo header field to represent system-wide OPTIONS request. With the above validations, nghttp2 library guarantees that header field name passed to `nghttp2_on_header_callback()` is not empty. Also required pseudo headers are all present and not empty. nghttp2 enforces "Content-Length" validation as well. All request or response headers must not contain more than one "Content-Length" header field. If "Content-Length" header field is present, it must be parsed as 64 bit signed integer. The sum of data length in the following DATA frames must match with the number in "Content-Length" header field if it is present (this does not include padding bytes). RFC 7230 says that server must not send "Content-Length" in any response with 1xx, and 204 status code. It also says that "Content-Length" is not allowed in any response with 200 status code to a CONNECT request. nghttp2 enforces them as well. Any deviation results in stream error of type PROTOCOL_ERROR. If error is found in PUSH_PROMISE frame, stream error is raised against promised stream. The order of transmission of the HTTP/2 frames ---------------------------------------------- This section describes the internals of libnghttp2 about the scheduling of transmission of HTTP/2 frames. This is pretty much internal stuff, so the details could change in the future versions of the library. libnghttp2 categorizes HTTP/2 frames into 4 categories: urgent, regular, syn_stream, and data in the order of higher priority. The urgent category includes PING and SETTINGS. They are sent with highest priority. The order inside the category is FIFO. The regular category includes frames other than PING, SETTINGS, DATA, and HEADERS which does not create stream (which counts toward concurrent stream limit). The order inside the category is FIFO. The syn_stream category includes HEADERS frame which creates stream, that counts toward the concurrent stream limit. The data category includes DATA frame, and the scheduling among DATA frames are determined by HTTP/2 dependency tree. If the application wants to send frames in the specific order, and the default transmission order does not fit, it has to schedule frames by itself using the callbacks (e.g., :type:`nghttp2_on_frame_send_callback`). RST_STREAM has special side effect when it is submitted by `nghttp2_submit_rst_stream()`. It cancels all pending HEADERS and DATA frames whose stream ID matches the one in the RST_STREAM frame. This may cause unexpected behaviour for the application in some cases. For example, suppose that application wants to send RST_STREAM after sending response HEADERS and DATA. Because of the reason we mentioned above, the following code does not work: .. code-block:: c nghttp2_submit_response2(...) nghttp2_submit_rst_stream(...) RST_STREAM cancels HEADERS (and DATA), and just RST_STREAM is sent. The correct way is use :type:`nghttp2_on_frame_send_callback`, and after HEADERS and DATA frames are sent, issue `nghttp2_submit_rst_stream()`. FYI, :type:`nghttp2_on_frame_not_send_callback` tells you why frames are not sent. Implement user defined HTTP/2 non-critical extensions ----------------------------------------------------- As of nghttp2 v1.8.0, we have added HTTP/2 non-critical extension framework, which lets application send and receive user defined custom HTTP/2 non-critical extension frames. nghttp2 also offers built-in functionality to send and receive official HTTP/2 extension frames (e.g., ALTSVC frame). For these built-in handler, refer to the next section. To send extension frame, use `nghttp2_submit_extension()`, and implement :type:`nghttp2_pack_extension_callback`. The callback implements how to encode data into wire format. The callback must be set to :type:`nghttp2_session_callbacks` using `nghttp2_session_callbacks_set_pack_extension_callback()`. For example, we will illustrate how to send `ALTSVC `_ frame. .. code-block:: c typedef struct { const char *origin; const char *field; } alt_svc; nghttp2_ssize pack_extension_callback(nghttp2_session *session, uint8_t *buf, size_t len, const nghttp2_frame *frame, void *user_data) { const alt_svc *altsvc = (const alt_svc *)frame->ext.payload; size_t originlen = strlen(altsvc->origin); size_t fieldlen = strlen(altsvc->field); uint8_t *p; if (len < 2 + originlen + fieldlen || originlen > 0xffff) { return NGHTTP2_ERR_CANCEL; } p = buf; *p++ = originlen >> 8; *p++ = originlen & 0xff; memcpy(p, altsvc->origin, originlen); p += originlen; memcpy(p, altsvc->field, fieldlen); p += fieldlen; return p - buf; } This implements :type:`nghttp2_pack_extension_callback`. We have to set this callback to :type:`nghttp2_session_callbacks`: .. code-block:: c nghttp2_session_callbacks_set_pack_extension_callback( callbacks, pack_extension_callback); To send ALTSVC frame, call `nghttp2_submit_extension()`: .. code-block:: c static const alt_svc altsvc = {"example.com", "h2=\":8000\""}; nghttp2_submit_extension(session, 0xa, NGHTTP2_FLAG_NONE, 0, (void *)&altsvc); Notice that ALTSVC is use frame type ``0xa``. To receive extension frames, implement 2 callbacks: :type:`nghttp2_unpack_extension_callback` and :type:`nghttp2_on_extension_chunk_recv_callback`. :type:`nghttp2_unpack_extension_callback` implements the way how to decode wire format. :type:`nghttp2_on_extension_chunk_recv_callback` implements how to buffer the incoming extension payload. These callbacks must be set using `nghttp2_session_callbacks_set_unpack_extension_callback()` and `nghttp2_session_callbacks_set_on_extension_chunk_recv_callback()` respectively. The application also must tell the library which extension frame type it is willing to receive using `nghttp2_option_set_user_recv_extension_type()`. Note that the application has to create :type:`nghttp2_option` object for that purpose, and initialize session with it. We use ALTSVC again to illustrate how to receive extension frames. We use different ``alt_svc`` struct than the previous one. First implement 2 callbacks. We store incoming ALTSVC payload to global variable ``altsvc_buffer``. Don't do this in production code since this is not thread safe: .. code-block:: c typedef struct { const uint8_t *origin; size_t originlen; const uint8_t *field; size_t fieldlen; } alt_svc; /* buffers incoming ALTSVC payload */ uint8_t altsvc_buffer[4096]; /* The length of byte written to altsvc_buffer */ size_t altsvc_bufferlen = 0; int on_extension_chunk_recv_callback(nghttp2_session *session, const nghttp2_frame_hd *hd, const uint8_t *data, size_t len, void *user_data) { if (sizeof(altsvc_buffer) < altsvc_bufferlen + len) { altsvc_bufferlen = 0; return NGHTTP2_ERR_CANCEL; } memcpy(altsvc_buffer + altsvc_bufferlen, data, len); altsvc_bufferlen += len; return 0; } int unpack_extension_callback(nghttp2_session *session, void **payload, const nghttp2_frame_hd *hd, void *user_data) { uint8_t *origin, *field; size_t originlen, fieldlen; uint8_t *p, *end; alt_svc *altsvc; if (altsvc_bufferlen < 2) { altsvc_bufferlen = 0; return NGHTTP2_ERR_CANCEL; } p = altsvc_buffer; end = altsvc_buffer + altsvc_bufferlen; originlen = ((*p) << 8) + *(p + 1); p += 2; if (p + originlen > end) { altsvc_bufferlen = 0; return NGHTTP2_ERR_CANCEL; } origin = p; field = p + originlen; fieldlen = end - field; altsvc = (alt_svc *)malloc(sizeof(alt_svc)); altsvc->origin = origin; altsvc->originlen = originlen; altsvc->field = field; altsvc->fieldlen = fieldlen; *payload = altsvc; altsvc_bufferlen = 0; return 0; } Set these callbacks to :type:`nghttp2_session_callbacks`: .. code-block:: c nghttp2_session_callbacks_set_on_extension_chunk_recv_callback( callbacks, on_extension_chunk_recv_callback); nghttp2_session_callbacks_set_unpack_extension_callback( callbacks, unpack_extension_callback); In ``unpack_extension_callback`` above, we set unpacked ``alt_svc`` object to ``*payload``. nghttp2 library then, calls :type:`nghttp2_on_frame_recv_callback`, and ``*payload`` will be available as ``frame->ext.payload``: .. code-block:: c int on_frame_recv_callback(nghttp2_session *session, const nghttp2_frame *frame, void *user_data) { switch (frame->hd.type) { ... case 0xa: { alt_svc *altsvc = (alt_svc *)frame->ext.payload; fprintf(stderr, "ALTSVC frame received\n"); fprintf(stderr, " origin: %.*s\n", (int)altsvc->originlen, altsvc->origin); fprintf(stderr, " field : %.*s\n", (int)altsvc->fieldlen, altsvc->field); free(altsvc); break; } } return 0; } Finally, application should set the extension frame types it is willing to receive: .. code-block:: c nghttp2_option_set_user_recv_extension_type(option, 0xa); The :type:`nghttp2_option` must be set to :type:`nghttp2_session` on its creation: .. code-block:: c nghttp2_session_client_new2(&session, callbacks, user_data, option); How to use built-in HTTP/2 extension frame handlers --------------------------------------------------- In the previous section, we talked about the user defined HTTP/2 extension frames. In this section, we talk about HTTP/2 extension frame support built into nghttp2 library. As of this writing, nghttp2 supports ALTSVC extension frame. To send ALTSVC frame, use `nghttp2_submit_altsvc()` function. To receive ALTSVC frame through built-in functionality, application has to use `nghttp2_option_set_builtin_recv_extension_type()` to indicate the willingness of receiving ALTSVC frame: .. code-block:: c nghttp2_option_set_builtin_recv_extension_type(option, NGHTTP2_ALTSVC); This is very similar to the case when we used to receive user defined frames. If the same frame type is set using `nghttp2_option_set_builtin_recv_extension_type()` and `nghttp2_option_set_user_recv_extension_type()`, the latter takes precedence. Application can implement its own frame handler rather than using built-in handler. The :type:`nghttp2_option` must be set to :type:`nghttp2_session` on its creation, like so: .. code-block:: c nghttp2_session_client_new2(&session, callbacks, user_data, option); When ALTSVC is received, :type:`nghttp2_on_frame_recv_callback` will be called as usual. Stream priorities ----------------- The stream prioritization scheme described in :rfc:`7540`, which has been formally deprecated by :rfc:`9113`, has been removed. An application is advised to send :enum:`nghttp2_settings_id.NGHTTP2_SETTINGS_NO_RFC7540_PRIORITIES` of value of 1 via `nghttp2_submit_settings()`, and migrate to :rfc:`9218`. The sender of this settings value disables :rfc:`7540` priorities, and instead it enables :rfc:`9218` Extensible Prioritization Scheme. This new prioritization scheme has 2 methods to convey the stream priorities to a remote endpoint: Priority header field and PRIORITY_UPDATE frame. nghttp2 supports both methods. In order to receive and process PRIORITY_UPDATE frame, server has to call `nghttp2_option_set_builtin_recv_extension_type()` with NGHTTP2_PRIORITY_UPDATE as type argument (see the above section), and pass the option to `nghttp2_session_server_new2()` or `nghttp2_session_server_new3()` to create a server session. Client can send Priority header field via `nghttp2_submit_request2()`. It can also send PRIORITY_UPDATE frame via `nghttp2_submit_priority_update()`. Server processes Priority header field in a request header field and updates the stream priority unless HTTP messaging rule enforcement is disabled (see `nghttp2_option_set_no_http_messaging()`). nghttp2-1.70.0/doc/PaxHeaders/sources0000644000000000000000000000013215232371114014415 xustar0030 mtime=1785328204.759917976 30 atime=1785328204.816856135 30 ctime=1785328204.759917976 nghttp2-1.70.0/doc/sources/0000755000175100017510000000000015232371114015062 5ustar00runnerrunnernghttp2-1.70.0/doc/sources/PaxHeaders/index.rst0000644000000000000000000000013215232371061016334 xustar0030 mtime=1785328177.562956667 30 atime=1785328183.328518204 30 ctime=1785328204.751793926 nghttp2-1.70.0/doc/sources/index.rst0000644000175100017510000000215315232371061016725 0ustar00runnerrunner.. nghttp2 documentation main file, created by sphinx-quickstart on Sun Mar 11 22:57:49 2012.

It operates in several modes and each mode may require additional programs to work with. This article describes each operation mode and explains the intended use-cases. It also covers some useful options later. Default mode ------------ If nghttpx is invoked without :option:`--http2-proxy`, it operates in default mode. In this mode, it works as reverse proxy (gateway) for HTTP/3, HTTP/2 and HTTP/1 clients to backend servers. This is also known as "HTTP/2 router". By default, frontend connection is encrypted using SSL/TLS. So server's private key and certificate must be supplied to the command line (or through configuration file). In this case, the frontend protocol selection will be done via ALPN. To turn off encryption on frontend connection, use ``no-tls`` keyword in :option:`--frontend` option. HTTP/2 and HTTP/1 are available on the frontend, and an HTTP/1 connection can be upgraded to HTTP/2 using HTTP Upgrade. Starting HTTP/2 connection by sending HTTP/2 connection preface is also supported. In order to receive HTTP/3 traffic, use ``quic`` parameter in :option:`--frontend` option (.e.g, ``--frontend='*,443;quic'``) nghttpx can listen on multiple frontend addresses. This is achieved by using multiple :option:`--frontend` options. For each frontend address, TLS can be enabled or disabled. By default, backend connections are not encrypted. To enable TLS encryption on backend connections, use ``tls`` keyword in :option:`--backend` option. Using patterns and ``proto`` keyword in :option:`--backend` option, backend application protocol can be specified per host/request path pattern. It means that you can use both HTTP/2 and HTTP/1 in backend connections at the same time. Note that default backend protocol is HTTP/1.1. To use HTTP/2 in backend, you have to specify ``h2`` in ``proto`` keyword in :option:`--backend` explicitly. The backend is supposed to be a Web server. For example, to make nghttpx listen to encrypted HTTP/2 requests at port 8443, and a backend Web server is configured to listen to HTTP requests at port 8080 on the same host, run nghttpx command-line like this: .. code-block:: text $ nghttpx -f0.0.0.0,8443 -b127.0.0.1,8080 /path/to/server.key /path/to/server.crt Then an HTTP/2 enabled client can access the nghttpx server using HTTP/2. For example, you can send a GET request using nghttp: .. code-block:: text $ nghttp -nv https://localhost:8443/ HTTP/2 proxy mode ----------------- If nghttpx is invoked with :option:`--http2-proxy` (or its shorthand :option:`-s`) option, it operates in HTTP/2 proxy mode. The supported protocols in frontend and backend connections are the same as in `default mode`_. The difference is that this mode acts like a forward proxy and assumes the backend is an HTTP proxy server (e.g., Squid, Apache Traffic Server). HTTP/1 requests must include an absolute URI in request line. By default, the frontend connection is encrypted. So this mode is also called secure proxy. To turn off encryption on the frontend connection, use ``no-tls`` keyword in :option:`--frontend` option. The backend must be an HTTP proxy server. nghttpx supports multiple backend server addresses. It translates incoming requests to HTTP request to backend server. The backend server performs real proxy work for each request, for example, dispatching requests to the origin server and caching contents. The backend connection is not encrypted by default. To enable encryption, use ``tls`` keyword in :option:`--backend` option. The default backend protocol is HTTP/1.1. To use HTTP/2 in backend connection, use :option:`--backend` option, and specify ``h2`` in ``proto`` keyword explicitly. For example, to make nghttpx listen to encrypted HTTP/2 requests at port 8443, and a backend HTTP proxy server is configured to listen to HTTP/1 requests at port 8080 on the same host, run nghttpx command-line like this: .. code-block:: text $ nghttpx -s -f'*,8443' -b127.0.0.1,8080 /path/to/server.key /path/to/server.crt At the time of this writing, Firefox 41 and Chromium v46 can use nghttpx as HTTP/2 proxy. To make Firefox or Chromium use nghttpx as HTTP/2 proxy, user has to create proxy.pac script file like this: .. code-block:: javascript function FindProxyForURL(url, host) { return "HTTPS SERVERADDR:PORT"; } ``SERVERADDR`` and ``PORT`` is the hostname/address and port of the machine nghttpx is running. Please note that both Firefox and Chromium require valid certificate for secure proxy. For Firefox, open Preference window and select Advanced then click Network tab. Clicking Connection Settings button will show the dialog. Select "Automatic proxy configuration URL" and enter the path to proxy.pac file, something like this: .. code-block:: text file:///path/to/proxy.pac For Chromium, use following command-line: .. code-block:: text $ google-chrome --proxy-pac-url=file:///path/to/proxy.pac --use-npn As HTTP/1 proxy server, Squid may work as out-of-box. Traffic server requires to be configured as forward proxy. Here is the minimum configuration items to edit: .. code-block:: text CONFIG proxy.config.reverse_proxy.enabled INT 0 CONFIG proxy.config.url_remap.remap_required INT 0 Consult Traffic server `documentation `_ to know how to configure traffic server as forward proxy and its security implications. ALPN support ------------ ALPN support requires OpenSSL >= 1.0.2. Disable frontend SSL/TLS ------------------------ The frontend connections are encrypted with SSL/TLS by default. To turn off SSL/TLS, use ``no-tls`` keyword in :option:`--frontend` option. If this option is used, the private key and certificate are not required to run nghttpx. Enable backend SSL/TLS ---------------------- The backend connections are not encrypted by default. To enable SSL/TLS encryption, use ``tls`` keyword in :option:`--backend` option. Enable SSL/TLS on memcached connection -------------------------------------- By default, memcached connection is not encrypted. To enable encryption, use ``tls`` keyword in :option:`--tls-ticket-key-memcached`. Specifying additional server certificates ----------------------------------------- nghttpx accepts additional server private key and certificate pairs using :option:`--subcert` option. It can be used multiple times. Specifying additional CA certificate ------------------------------------ By default, nghttpx tries to read CA certificate from system. But depending on the system you use, this may fail or is not supported. To specify CA certificate manually, use :option:`--cacert` option. The specified file must be PEM format and can contain multiple certificates. By default, nghttpx validates server's certificate. If you want to turn off this validation, knowing this is really insecure and what you are doing, you can use :option:`--insecure` option to disable certificate validation. Read/write rate limit --------------------- nghttpx supports transfer rate limiting on frontend connections. You can do rate limit per frontend connection for reading and writing individually. To perform rate limit for reading, use :option:`--read-rate` and :option:`--read-burst` options. For writing, use :option:`--write-rate` and :option:`--write-burst`. Please note that rate limit is performed on top of TCP and nothing to do with HTTP/2 flow control. Rewriting location header field ------------------------------- nghttpx automatically rewrites location response header field if the following all conditions satisfy: * In the default mode (:option:`--http2-proxy` is not used) * :option:`--no-location-rewrite` is not used * URI in location header field is an absolute URI * URI in location header field includes non empty host component. * host (without port) in URI in location header field must match the host appearing in ``:authority`` or ``host`` header field. When rewrite happens, URI scheme is replaced with the ones used in frontend, and authority is replaced with which appears in ``:authority``, or ``host`` request header field. ``:authority`` header field has precedence over ``host``. Hot swapping ------------ nghttpx supports hot swapping using signals. The hot swapping in nghttpx is multi step process. First send USR2 signal to nghttpx process. It will do fork and execute new executable, using same command-line arguments and environment variables. As of nghttpx version 1.20.0, that is all you have to do. The new main process sends QUIT signal to the original process, when it is ready to serve requests, to shut it down gracefully. For earlier versions of nghttpx, you have to do one more thing. At this point, both current and new processes can accept requests. To gracefully shutdown current process, send QUIT signal to current nghttpx process. When all existing frontend connections are done, the current process will exit. At this point, only new nghttpx process exists and serves incoming requests. If you want to just reload configuration file without executing new binary, send SIGHUP to nghttpx main process. For TCP connections, nghttpx does moderate effort not to lose a connection during this process. To make it more robust, consider to enable ``net.ipv4.tcp_migrate_req``. Re-opening log files -------------------- When rotating log files, it is desirable to re-open log files after log rotation daemon renamed existing log files. To tell nghttpx to re-open log files, send USR1 signal to nghttpx process. It will re-open files specified by :option:`--accesslog-file` and :option:`--errorlog-file` options. Multiple frontend addresses --------------------------- nghttpx can listen on multiple frontend addresses. To specify them, just use :option:`--frontend` (or its shorthand :option:`-f`) option repeatedly. TLS can be enabled or disabled per frontend address basis. For example, to listen on port 443 with TLS enabled, and on port 80 without TLS: .. code-block:: text frontend=*,443 frontend=*,80;no-tls Multiple backend addresses -------------------------- nghttpx supports multiple backend addresses. To specify them, just use :option:`--backend` (or its shorthand :option:`-b`) option repeatedly. For example, to use ``192.168.0.10:8080`` and ``192.168.0.11:8080``, use command-line like this: ``-b192.168.0.10,8080 -b192.168.0.11,8080``. In configuration file, this looks like: .. code-block:: text backend=192.168.0.10,8080 backend=192.168.0.11,8008 nghttpx can route request to different backend according to request host and path. For example, to route request destined to host ``doc.example.com`` to backend server ``docserv:3000``, you can write like so: .. code-block:: text backend=docserv,3000;doc.example.com/ When you write this option in command-line, you should enclose argument with single or double quotes, since the character ``;`` has a special meaning in shell. To route, request to request path ``/foo`` to backend server ``[::1]:8080``, you can write like so: .. code-block:: text backend=::1,8080;/foo If the last character of path pattern is ``/``, all request paths which start with that pattern match: .. code-block:: text backend=::1,8080;/bar/ The request path ``/bar/buzz`` matches the ``/bar/``. You can use ``*`` at the end of the path pattern to make it wildcard pattern. ``*`` must match at least one character: .. code-block:: text backend=::1,8080;/sample* The request path ``/sample1/foo`` matches the ``/sample*`` pattern. Of course, you can specify both host and request path at the same time: .. code-block:: text backend=192.168.0.10,8080;example.com/foo We can use ``*`` in the left most position of host to achieve wildcard suffix match. If ``*`` is the left most character, then the remaining string should match the request host suffix. ``*`` must match at least one character. For example, ``*.example.com`` matches ``www.example.com`` and ``dev.example.com``, and does not match ``example.com`` and ``nghttp2.org``. The exact match (without ``*``) always takes precedence over wildcard match. One important thing you have to remember is that we have to specify default routing pattern for so called "catch all" pattern. To write "catch all" pattern, just specify backend server address, without pattern. Usually, host is the value of ``Host`` header field. In HTTP/2, the value of ``:authority`` pseudo header field is used. When you write multiple backend addresses sharing the same routing pattern, they are used as load balancing. For example, to use 2 servers ``serv1:3000`` and ``serv2:3000`` for request host ``example.com`` and path ``/myservice``, you can write like so: .. code-block:: text backend=serv1,3000;example.com/myservice backend=serv2,3000;example.com/myservice You can also specify backend application protocol in :option:`--backend` option using ``proto`` keyword after pattern. Utilizing this allows ngttpx to route certain request to HTTP/2, other requests to HTTP/1. For example, to route requests to ``/ws/`` in backend HTTP/1.1 connection, and use backend HTTP/2 for other requests, do this: .. code-block:: text backend=serv1,3000;/;proto=h2 backend=serv1,3000;/ws/;proto=http/1.1 The default backend protocol is HTTP/1.1. TLS can be enabled per pattern basis: .. code-block:: text backend=serv1,8443;/;proto=h2;tls backend=serv2,8080;/ws/;proto=http/1.1 In the above case, connection to serv1 will be encrypted by TLS. On the other hand, connection to serv2 will not be encrypted by TLS. Dynamic hostname lookup ----------------------- By default, nghttpx performs backend hostname lookup at start up, or configuration reload, and keeps using them in its entire session. To make nghttpx perform hostname lookup dynamically, use ``dns`` parameter in :option:`--backend` option, like so: .. code-block:: text backend=foo.example.com,80;;dns nghttpx will cache resolved addresses for certain period of time. To change this cache period, use :option:`--dns-cache-timeout`. Enable PROXY protocol --------------------- PROXY protocol can be enabled per frontend. In order to enable PROXY protocol, use ``proxyproto`` parameter in :option:`--frontend` option, like so: .. code-block:: text frontend=*,443;proxyproto nghttpx supports both PROXY protocol v1 and v2. AF_UNIX in PROXY protocol version 2 is ignored. Session affinity ---------------- Two kinds of session affinity are available: client IP, and HTTP Cookie. To enable client IP based affinity, specify ``affinity=ip`` parameter in :option:`--backend` option. If PROXY protocol is enabled, then an address obtained from PROXY protocol is taken into consideration. To enable HTTP Cookie based affinity, specify ``affinity=cookie`` parameter, and specify a name of cookie in ``affinity-cookie-name`` parameter. Optionally, a Path attribute can be specified in ``affinity-cookie-path`` parameter: .. code-block:: text backend=127.0.0.1,3000;;affinity=cookie;affinity-cookie-name=nghttpxlb;affinity-cookie-path=/ Secure attribute of cookie is set if client connection is protected by TLS. ``affinity-cookie-stickiness`` specifies the stickiness of this affinity. If ``loose`` is given, which is the default, removing or adding a backend server might break affinity. While ``strict`` is given, removing the designated backend server breaks affinity, but adding new backend server does not cause breakage. PSK cipher suites ----------------- nghttpx supports pre-shared key (PSK) cipher suites for both frontend and backend TLS connections. For frontend connection, use :option:`--psk-secrets` option to specify a file which contains PSK identity and secrets. The format of the file is ``:``, where ```` is PSK identity, and ```` is PSK secret in hex, like so: .. code-block:: text client1:9567800e065e078085c241d54a01c6c3f24b3bab71a606600f4c6ad2c134f3b9 client2:b1376c3f8f6dcf7c886c5bdcceecd1e6f1d708622b6ddd21bda26ebd0c0bca99 nghttpx server accepts any of the identity and secret pairs in the file. The default cipher suite list does not contain PSK cipher suites. In order to use PSK, PSK cipher suite must be enabled by using :option:`--ciphers` option. The desired PSK cipher suite may be listed in `HTTP/2 cipher block list `_. In order to use such PSK cipher suite with HTTP/2, disable HTTP/2 cipher block list by using :option:`--no-http2-cipher-block-list` option. But you should understand its implications. At the time of writing, even if only PSK cipher suites are specified in :option:`--ciphers` option, certificate and private key are still required. For backend connection, use :option:`--client-psk-secrets` option to specify a file which contains single PSK identity and secret. The format is the same as the file used by :option:`--psk-secrets` described above, but only first identity and secret pair is solely used, like so: .. code-block:: text client2:b1376c3f8f6dcf7c886c5bdcceecd1e6f1d708622b6ddd21bda26ebd0c0bca99 The default cipher suite list does not contain PSK cipher suites. In order to use PSK, PSK cipher suite must be enabled by using :option:`--client-ciphers` option. The desired PSK cipher suite may be listed in `HTTP/2 cipher block list `_. In order to use such PSK cipher suite with HTTP/2, disable HTTP/2 cipher block list by using :option:`--client-no-http2-cipher-block-list` option. But you should understand its implications. TLSv1.3 ------- As of nghttpx v1.34.0, if it is built with OpenSSL 1.1.1 or later, it supports TLSv1.3. 0-RTT data is supported, but by default its processing is postponed until TLS handshake completes to mitigate replay attack. This costs extra round trip and reduces effectiveness of 0-RTT data. :option:`--tls-no-postpone-early-data` makes nghttpx not wait for handshake to complete before forwarding request included in 0-RTT to get full potential of 0-RTT data. In this case, nghttpx adds ``Early-Data: 1`` header field when forwarding a request to a backend server. All backend servers should recognize this header field and understand that there is a risk for replay attack. See `RFC 8470 `_ for ``Early-Data`` header field. nghttpx disables anti replay protection provided by OpenSSL. The anti replay protection of OpenSSL requires that a resumed request must hit the same server which generates the session ticket. Therefore it might not work nicely in a deployment where there are multiple nghttpx instances sharing ticket encryption keys via memcached. Because TLSv1.3 completely changes the semantics of cipher suite naming scheme and structure, nghttpx provides the new option :option:`--tls13-ciphers` and :option:`--tls13-client-ciphers` to change preferred cipher list for TLSv1.3. Encrypted Client Hello ---------------------- nghttpx supports `RFC 9849 `_ Encrypted Client Hello (ECH) on the frontend connections if the underlying TLS stack supports it. To setup ECH, use the following options: - :option:`--ech-config-file` - :option:`--ech-retry-config-file` These options take the path to PEM ECH file as described in `RFC 9934 `_. They can be used repeatedly to specify the multiple HPKE private keys and ECH configurations. :option:`--ech-retry-config-file` must be used at least once when enabling ECH. WebSockets over HTTP/2 ---------------------- nghttpx supports `RFC 8441 `_ Bootstrapping WebSockets with HTTP/2 for both frontend and backend connections. This feature is enabled by default and no configuration is required. WebSockets over HTTP/3 is also supported. HTTP/3 ------ nghttpx supports HTTP/3 if it is built with HTTP/3 support enabled. HTTP/3 support is experimental. In order to listen UDP port to receive HTTP/3 traffic, :option:`--frontend` option must have ``quic`` parameter: .. code-block:: text frontend=*,443;quic The above example makes nghttpx receive HTTP/3 traffic on UDP port 443. nghttpx does not support HTTP/3 on backend connection. Hot swapping (SIGUSR2) or configuration reload (SIGHUP) require eBPF program. Without eBPF, old worker processes keep getting HTTP/3 traffic and do not work as intended. The QUIC keying material to encrypt Connection ID must be set with :option:`--frontend-quic-secret-file` and must provide the existing keys in order to keep the existing connections alive during reload. The construction of Connection ID closely follows Block Cipher CID Algorithm described in `QUIC-LB draft `_. A Connection ID that nghttpx generates is always 17 bytes long. It uses first 3 bits as a configuration ID. The remaining bits in the first byte are reserved and random. The next 4 bytes are server ID. The next 4 bytes are used to route UDP datagram to a correct ``SO_REUSEPORT`` socket. The remaining bytes are randomly generated. The server ID and the next 12 bytes are encrypted with AES-ECB. The key is derived from the keying materials stored in a file specified by :option:`--frontend-quic-secret-file`. The first 2 bits of keying material in the file is used as a configuration ID. The remaining bits and following 3 bytes are reserved and unused. The next 32 bytes are used as an initial secret. The remaining 32 bytes are used as a salt. The encryption key is generated by `HKDF `_ with SHA256 and these keying materials and ``connection id encryption key`` as info. In order announce that HTTP/3 endpoint is available, you should specify alt-svc header field. For example, the following options send alt-svc header field in HTTP/1.1 and HTTP/2 response: .. code-block:: text altsvc=h3,443,,,ma=3600 http2-altsvc=h3,443,,,ma=3600 Migration from nghttpx v1.18.x or earlier ----------------------------------------- As of nghttpx v1.19.0, :option:`--ciphers` option only changes cipher list for frontend TLS connection. In order to change cipher list for backend connection, use :option:`--client-ciphers` option. Similarly, :option:`--no-http2-cipher-block-list` option only disables HTTP/2 cipher block list for frontend connection. In order to disable HTTP/2 cipher block list for backend connection, use :option:`--client-no-http2-cipher-block-list` option. ``--accept-proxy-protocol`` option was deprecated. Instead, use ``proxyproto`` parameter in :option:`--frontend` option to enable PROXY protocol support per frontend. Migration from nghttpx v1.8.0 or earlier ---------------------------------------- As of nghttpx 1.9.0, ``--frontend-no-tls`` and ``--backend-no-tls`` have been removed. To disable encryption on frontend connection, use ``no-tls`` keyword in :option:`--frontend` potion: .. code-block:: text frontend=*,3000;no-tls The TLS encryption is now disabled on backend connection in all modes by default. To enable encryption on backend connection, use ``tls`` keyword in :option:`--backend` option: .. code-block:: text backend=127.0.0.1,8080;tls As of nghttpx 1.9.0, ``--http2-bridge``, ``--client`` and ``--client-proxy`` options have been removed. These functionality can be used using combinations of options. Use following option instead of ``--http2-bridge``: .. code-block:: text backend=,;;proto=h2;tls Use following options instead of ``--client``: .. code-block:: text frontend=,;no-tls backend=,;;proto=h2;tls Use following options instead of ``--client-proxy``: .. code-block:: text http2-proxy=yes frontend=,;no-tls backend=,;;proto=h2;tls We also removed ``--backend-http2-connections-per-worker`` option. It was present because previously the number of backend h2 connection was statically configured, and defaulted to 1. Now the number of backend h2 connection is increased on demand. We know the maximum number of concurrent streams per connection. When we push as many request as the maximum concurrency to the one connection, we create another new connection so that we can distribute load and avoid delay the request processing. This is done automatically without any configuration. nghttp2-1.70.0/doc/sources/PaxHeaders/tutorial-client.rst0000644000000000000000000000013215232371061020344 xustar0030 mtime=1785328177.562956667 30 atime=1785328183.328518204 30 ctime=1785328204.753208761 nghttp2-1.70.0/doc/sources/tutorial-client.rst0000644000175100017510000004513215232371061020741 0ustar00runnerrunnerTutorial: HTTP/2 client ========================= In this tutorial, we are going to write a very primitive HTTP/2 client. The complete source code, `libevent-client.c`_, is attached at the end of this page. It also resides in the examples directory in the archive or repository. This simple client takes a single HTTPS URI and retrieves the resource at the URI. The synopsis is: .. code-block:: text $ libevent-client HTTPS_URI We use libevent in this tutorial to handle networking I/O. Please note that nghttp2 itself does not depend on libevent. The client starts with some libevent and OpenSSL setup in the ``main()`` and ``run()`` functions. This setup isn't specific to nghttp2, but one thing you should look at is setup of ALPN. Client tells application protocols that it supports to server via ALPN:: static SSL_CTX *create_ssl_ctx(void) { SSL_CTX *ssl_ctx; ssl_ctx = SSL_CTX_new(SSLv23_client_method()); if (!ssl_ctx) { errx(1, "Could not create SSL/TLS context: %s", ERR_error_string(ERR_get_error(), NULL)); } SSL_CTX_set_options(ssl_ctx, SSL_OP_ALL | SSL_OP_NO_SSLv2 | SSL_OP_NO_SSLv3 | SSL_OP_NO_COMPRESSION | SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION); SSL_CTX_set_alpn_protos(ssl_ctx, (const unsigned char *)"\x02h2", 3); return ssl_ctx; } Here we see ``SSL_CTX_get_alpn_protos()`` function call. We instructs OpenSSL to notify the server that we support h2, ALPN identifier for HTTP/2. The example client defines a couple of structs: We define and use a ``http2_session_data`` structure to store data related to the HTTP/2 session:: typedef struct { nghttp2_session *session; struct evdns_base *dnsbase; struct bufferevent *bev; http2_stream_data *stream_data; } http2_session_data; Since this program only handles one URI, it uses only one stream. We store the single stream's data in a ``http2_stream_data`` structure and the ``stream_data`` points to it. The ``http2_stream_data`` structure is defined as follows:: typedef struct { /* The NULL-terminated URI string to retrieve. */ const char *uri; /* Parsed result of the |uri| */ urlparse_url *u; /* The authority portion of the |uri|, not NULL-terminated */ char *authority; /* The path portion of the |uri|, including query, not NULL-terminated */ char *path; /* The length of the |authority| */ size_t authoritylen; /* The length of the |path| */ size_t pathlen; /* The stream ID of this stream */ int32_t stream_id; } http2_stream_data; We create and initialize these structures in ``create_http2_session_data()`` and ``create_http2_stream_data()`` respectively. ``initiate_connection()`` is called to start the connection to the remote server. It's defined as:: static void initiate_connection(struct event_base *evbase, SSL_CTX *ssl_ctx, const char *host, uint16_t port, http2_session_data *session_data) { int rv; struct bufferevent *bev; SSL *ssl; ssl = create_ssl(ssl_ctx); bev = bufferevent_openssl_socket_new( evbase, -1, ssl, BUFFEREVENT_SSL_CONNECTING, BEV_OPT_DEFER_CALLBACKS | BEV_OPT_CLOSE_ON_FREE); bufferevent_enable(bev, EV_READ | EV_WRITE); bufferevent_setcb(bev, readcb, writecb, eventcb, session_data); rv = bufferevent_socket_connect_hostname(bev, session_data->dnsbase, AF_UNSPEC, host, port); if (rv != 0) { errx(1, "Could not connect to the remote host %s", host); } session_data->bev = bev; } ``initiate_connection()`` creates a bufferevent for the connection and sets up three callbacks: ``readcb``, ``writecb``, and ``eventcb``. The ``eventcb()`` is invoked by the libevent event loop when an event (e.g. connection has been established, timeout, etc.) occurs on the underlying network socket:: static void eventcb(struct bufferevent *bev, short events, void *ptr) { http2_session_data *session_data = (http2_session_data *)ptr; if (events & BEV_EVENT_CONNECTED) { int fd = bufferevent_getfd(bev); int val = 1; const unsigned char *alpn = NULL; unsigned int alpnlen = 0; SSL *ssl; fprintf(stderr, "Connected\n"); ssl = bufferevent_openssl_get_ssl(session_data->bev); SSL_get0_alpn_selected(ssl, &alpn, &alpnlen); if (alpn == NULL || alpnlen != 2 || memcmp("h2", alpn, 2) != 0) { fprintf(stderr, "h2 is not negotiated\n"); delete_http2_session_data(session_data); return; } setsockopt(fd, IPPROTO_TCP, TCP_NODELAY, (char *)&val, sizeof(val)); initialize_nghttp2_session(session_data); send_client_connection_header(session_data); submit_request(session_data); if (session_send(session_data) != 0) { delete_http2_session_data(session_data); } return; } if (events & BEV_EVENT_EOF) { warnx("Disconnected from the remote host"); } else if (events & BEV_EVENT_ERROR) { warnx("Network error"); } else if (events & BEV_EVENT_TIMEOUT) { warnx("Timeout"); } delete_http2_session_data(session_data); } Here we validate that HTTP/2 is negotiated, and if not, drop connection. For ``BEV_EVENT_EOF``, ``BEV_EVENT_ERROR``, and ``BEV_EVENT_TIMEOUT`` events, we just simply tear down the connection. The ``BEV_EVENT_CONNECTED`` event is invoked when the SSL/TLS handshake has completed successfully. After this we're ready to begin communicating via HTTP/2. The ``initialize_nghttp2_session()`` function initializes the nghttp2 session object and several callbacks:: static void initialize_nghttp2_session(http2_session_data *session_data) { nghttp2_session_callbacks *callbacks; nghttp2_session_callbacks_new(&callbacks); nghttp2_session_callbacks_set_send_callback2(callbacks, send_callback); nghttp2_session_callbacks_set_on_frame_recv_callback(callbacks, on_frame_recv_callback); nghttp2_session_callbacks_set_on_data_chunk_recv_callback( callbacks, on_data_chunk_recv_callback); nghttp2_session_callbacks_set_on_stream_close_callback( callbacks, on_stream_close_callback); nghttp2_session_callbacks_set_on_header_callback(callbacks, on_header_callback); nghttp2_session_callbacks_set_on_begin_headers_callback( callbacks, on_begin_headers_callback); nghttp2_session_client_new(&session_data->session, callbacks, session_data); nghttp2_session_callbacks_del(callbacks); } Since we are creating a client, we use `nghttp2_session_client_new()` to initialize the nghttp2 session object. The callbacks setup are explained later. The `delete_http2_session_data()` function destroys ``session_data`` and frees its bufferevent, so the underlying connection is closed. It also calls `nghttp2_session_del()` to delete the nghttp2 session object. A HTTP/2 connection begins by sending the client connection preface, which is a 24 byte magic byte string (:macro:`NGHTTP2_CLIENT_MAGIC`), followed by a SETTINGS frame. The 24 byte magic string is sent automatically by nghttp2. We send the SETTINGS frame in ``send_client_connection_header()``:: static void send_client_connection_header(http2_session_data *session_data) { nghttp2_settings_entry iv[1] = { {NGHTTP2_SETTINGS_MAX_CONCURRENT_STREAMS, 100}}; int rv; /* client 24 bytes magic string will be sent by nghttp2 library */ rv = nghttp2_submit_settings(session_data->session, NGHTTP2_FLAG_NONE, iv, ARRLEN(iv)); if (rv != 0) { errx(1, "Could not submit SETTINGS: %s", nghttp2_strerror(rv)); } } Here we specify SETTINGS_MAX_CONCURRENT_STREAMS as 100. This is not needed for this tiny example program, it just demonstrates use of the SETTINGS frame. To queue the SETTINGS frame for transmission, we call `nghttp2_submit_settings()`. Note that `nghttp2_submit_settings()` only queues the frame for transmission, and doesn't actually send it. All ``nghttp2_submit_*()`` family functions have this property. To actually send the frame, `nghttp2_session_send()` has to be called, which is described (and called) later. After the transmission of the client connection header, we enqueue the HTTP request in the ``submit_request()`` function:: static void submit_request(http2_session_data *session_data) { int32_t stream_id; http2_stream_data *stream_data = session_data->stream_data; const char *uri = stream_data->uri; const urlparse_url *u = stream_data->u; nghttp2_nv hdrs[] = { MAKE_NV2(":method", "GET"), MAKE_NV(":scheme", &uri[u->field_data[URLPARSE_SCHEMA].off], u->field_data[URLPARSE_SCHEMA].len), MAKE_NV(":authority", stream_data->authority, stream_data->authoritylen), MAKE_NV(":path", stream_data->path, stream_data->pathlen)}; fprintf(stderr, "Request headers:\n"); print_headers(stderr, hdrs, ARRLEN(hdrs)); stream_id = nghttp2_submit_request2(session_data->session, NULL, hdrs, ARRLEN(hdrs), NULL, stream_data); if (stream_id < 0) { errx(1, "Could not submit HTTP request: %s", nghttp2_strerror(stream_id)); } stream_data->stream_id = stream_id; } We build the HTTP request header fields in ``hdrs``, which is an array of :type:`nghttp2_nv`. There are four header fields to be sent: ``:method``, ``:scheme``, ``:authority``, and ``:path``. To queue the HTTP request, we call `nghttp2_submit_request2()`. The ``stream_data`` is passed via the *stream_user_data* parameter, which is helpfully later passed back to callback functions. `nghttp2_submit_request2()` returns the newly assigned stream ID for the request. The next bufferevent callback is ``readcb()``, which is invoked when data is available to read from the bufferevent input buffer:: static void readcb(struct bufferevent *bev, void *ptr) { http2_session_data *session_data = (http2_session_data *)ptr; nghttp2_ssize readlen; struct evbuffer *input = bufferevent_get_input(bev); size_t datalen = evbuffer_get_length(input); unsigned char *data = evbuffer_pullup(input, -1); readlen = nghttp2_session_mem_recv2(session_data->session, data, datalen); if (readlen < 0) { warnx("Fatal error: %s", nghttp2_strerror((int)readlen)); delete_http2_session_data(session_data); return; } if (evbuffer_drain(input, (size_t)readlen) != 0) { warnx("Fatal error: evbuffer_drain failed"); delete_http2_session_data(session_data); return; } if (session_send(session_data) != 0) { delete_http2_session_data(session_data); return; } } In this function we feed all unprocessed, received data to the nghttp2 session object using the `nghttp2_session_mem_recv2()` function. `nghttp2_session_mem_recv2()` processes the received data and may invoke nghttp2 callbacks and queue frames for transmission. Since there may be pending frames for transmission, we call immediately ``session_send()`` to send them. ``session_send()`` is defined as follows:: static int session_send(http2_session_data *session_data) { int rv; rv = nghttp2_session_send(session_data->session); if (rv != 0) { warnx("Fatal error: %s", nghttp2_strerror(rv)); return -1; } return 0; } The `nghttp2_session_send()` function serializes pending frames into wire format and calls the ``send_callback()`` function to send them. ``send_callback()`` has type :type:`nghttp2_send_callback2` and is defined as:: static nghttp2_ssize send_callback(nghttp2_session *session _U_, const uint8_t *data, size_t length, int flags _U_, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; struct bufferevent *bev = session_data->bev; bufferevent_write(bev, data, length); return (nghttp2_ssize)length; } Since we use bufferevent to abstract network I/O, we just write the data to the bufferevent object. Note that `nghttp2_session_send()` continues to write all frames queued so far. If we were writing the data to the non-blocking socket directly using the ``write()`` system call, we'd soon receive an ``EAGAIN`` or ``EWOULDBLOCK`` error, since sockets have a limited send buffer. If that happens, it's possible to return :macro:`NGHTTP2_ERR_WOULDBLOCK` to signal the nghttp2 library to stop sending further data. When writing to a bufferevent, you should regulate the amount of data written, to avoid possible huge memory consumption. In this example client however we don't implement a limit. To see how to regulate the amount of buffered data, see the ``send_callback()`` in the server tutorial. The third bufferevent callback is ``writecb()``, which is invoked when all data written in the bufferevent output buffer has been sent:: static void writecb(struct bufferevent *bev _U_, void *ptr) { http2_session_data *session_data = (http2_session_data *)ptr; if (nghttp2_session_want_read(session_data->session) == 0 && nghttp2_session_want_write(session_data->session) == 0 && evbuffer_get_length(bufferevent_get_output(session_data->bev)) == 0) { delete_http2_session_data(session_data); } } As described earlier, we just write off all data in `send_callback()`, so there is no data to write in this function. All we have to do is check if the connection should be dropped or not. The nghttp2 session object keeps track of reception and transmission of GOAWAY frames and other error conditions. Using this information, the nghttp2 session object can state whether the connection should be dropped or not. More specifically, when both `nghttp2_session_want_read()` and `nghttp2_session_want_write()` return 0, the connection is no-longer required and can be closed. Since we're using bufferevent and its deferred callback option, the bufferevent output buffer may still contain pending data when the ``writecb()`` is called. To handle this situation, we also check whether the output buffer is empty or not. If all of these conditions are met, then we drop the connection. Now let's look at the remaining nghttp2 callbacks setup in the ``initialize_nghttp2_setup()`` function. A server responds to the request by first sending a HEADERS frame. The HEADERS frame consists of response header name/value pairs, and the ``on_header_callback()`` is called for each name/value pair:: static int on_header_callback(nghttp2_session *session _U_, const nghttp2_frame *frame, const uint8_t *name, size_t namelen, const uint8_t *value, size_t valuelen, uint8_t flags _U_, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; switch (frame->hd.type) { case NGHTTP2_HEADERS: if (frame->headers.cat == NGHTTP2_HCAT_RESPONSE && session_data->stream_data->stream_id == frame->hd.stream_id) { /* Print response headers for the initiated request. */ print_header(stderr, name, namelen, value, valuelen); break; } } return 0; } In this tutorial, we just print the name/value pairs on stderr. After the HEADERS frame has been fully received (and thus all response header name/value pairs have been received), the ``on_frame_recv_callback()`` function is called:: static int on_frame_recv_callback(nghttp2_session *session _U_, const nghttp2_frame *frame, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; switch (frame->hd.type) { case NGHTTP2_HEADERS: if (frame->headers.cat == NGHTTP2_HCAT_RESPONSE && session_data->stream_data->stream_id == frame->hd.stream_id) { fprintf(stderr, "All headers received\n"); } break; } return 0; } ``on_frame_recv_callback()`` is called for other frame types too. In this tutorial, we are just interested in the HTTP response HEADERS frame. We check the frame type and its category (it should be :macro:`NGHTTP2_HCAT_RESPONSE` for HTTP response HEADERS). We also check its stream ID. Next, zero or more DATA frames can be received. The ``on_data_chunk_recv_callback()`` function is invoked when a chunk of data is received from the remote peer:: static int on_data_chunk_recv_callback(nghttp2_session *session _U_, uint8_t flags _U_, int32_t stream_id, const uint8_t *data, size_t len, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; if (session_data->stream_data->stream_id == stream_id) { fwrite(data, len, 1, stdout); } return 0; } In our case, a chunk of data is HTTP response body. After checking the stream ID, we just write the received data to stdout. Note the output in the terminal may be corrupted if the response body contains some binary data. The ``on_stream_close_callback()`` function is invoked when the stream is about to close:: static int on_stream_close_callback(nghttp2_session *session, int32_t stream_id, nghttp2_error_code error_code, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; int rv; if (session_data->stream_data->stream_id == stream_id) { fprintf(stderr, "Stream %d closed with error_code=%d\n", stream_id, error_code); rv = nghttp2_session_terminate_session(session, NGHTTP2_NO_ERROR); if (rv != 0) { return NGHTTP2_ERR_CALLBACK_FAILURE; } } return 0; } If the stream ID matches the one we initiated, it means that its stream is going to be closed. Since we have finished receiving resource we wanted (or the stream was reset by RST_STREAM from the remote peer), we call `nghttp2_session_terminate_session()` to commence closure of the HTTP/2 session gracefully. If you have some data associated for the stream to be closed, you may delete it here. nghttp2-1.70.0/doc/sources/PaxHeaders/h2load-howto.rst0000644000000000000000000000013215232371061017534 xustar0030 mtime=1785328177.562956667 30 atime=1785328183.328518204 30 ctime=1785328204.757854781 nghttp2-1.70.0/doc/sources/h2load-howto.rst0000644000175100017510000001131715232371061020127 0ustar00runnerrunner.. program:: h2load h2load - HTTP/2 benchmarking tool - HOW-TO ========================================== :doc:`h2load.1` is benchmarking tool for HTTP/2 and HTTP/1.1. It supports SSL/TLS and clear text for all supported protocols. Compiling from source --------------------- h2load is compiled alongside nghttp2 and requires that the ``--enable-app`` flag is passed to ``./configure`` and `required dependencies `_ are available during compilation. For details on compiling, see `nghttp2: Building from Git `_. Basic Usage ----------- In order to set benchmark settings, specify following 3 options. :option:`-n` The number of total requests. Default: 1 :option:`-c` The number of concurrent clients. Default: 1 :option:`-m` The max concurrent streams to issue per client. Default: 1 For SSL/TLS connection, the protocol will be negotiated via ALPN. You can set specific protocols in :option:`--alpn-list` option. For cleartext connection, the default protocol is HTTP/2. To change the protocol in cleartext connection, use :option:`--no-tls-proto` option. For convenience, :option:`--h1` option forces HTTP/1.1 for both cleartext and SSL/TLS connections. Here is a command-line to perform benchmark to URI \https://localhost using total 100000 requests, 100 concurrent clients and 10 max concurrent streams: .. code-block:: text $ h2load -n100000 -c100 -m10 https://localhost The benchmarking result looks like this: .. code-block:: text finished in 7.08s, 141164.80 req/s, 555.33MB/s requests: 1000000 total, 1000000 started, 1000000 done, 1000000 succeeded, 0 failed, 0 errored, 0 timeout status codes: 1000000 2xx, 0 3xx, 0 4xx, 0 5xx traffic: 4125025824 bytes total, 11023424 bytes headers (space savings 93.07%), 4096000000 bytes data min max mean sd +/- sd time for request: 15.31ms 146.85ms 69.78ms 9.26ms 92.43% time for connect: 1.08ms 25.04ms 10.71ms 9.80ms 64.00% time to 1st byte: 25.36ms 184.96ms 79.11ms 53.97ms 78.00% req/s (client) : 1412.04 1447.84 1426.52 10.57 63.00% See the h2load manual page :ref:`h2load-1-output` section for the explanation of the above numbers. Timing-based load-testing ------------------------- As of v1.26.0, h2load supports timing-based load-testing. This method performs load-testing in terms of a given duration instead of a pre-defined number of requests. The new option :option:`--duration` specifies how long the load-testing takes. For example, ``--duration=10`` makes h2load perform load-testing against a server for 10 seconds. You can also specify a “warming-up†period with :option:`--warm-up-time`. If :option:`--duration` is used, :option:`-n` option is ignored. The following command performs load-testing for 10 seconds after 5 seconds warming up period: .. code-block:: text $ h2load -c100 -m100 --duration=10 --warm-up-time=5 https://localhost Flow Control ------------ HTTP/2 has flow control and it may affect benchmarking results. By default, h2load uses large enough flow control window, which effectively disables flow control. To adjust receiver flow control window size, there are following options: :option:`-w` Sets the stream level initial window size to (2**)-1. :option:`-W` Sets the connection level initial window size to (2**)-1. Multi-Threading --------------- Sometimes benchmarking client itself becomes a bottleneck. To remedy this situation, use :option:`-t` option to specify the number of native thread to use. :option:`-t` The number of native threads. Default: 1 Selecting protocol for clear text --------------------------------- By default, if \http:// URI is given, HTTP/2 protocol is used. To change the protocol to use for clear text, use :option:`-p` option. Multiple URIs ------------- If multiple URIs are specified, they are used in round robin manner. .. note:: Please note that h2load uses scheme, host and port in the first URI and ignores those parts in the rest of the URIs. UNIX domain socket ------------------ To request against UNIX domain socket, use :option:`--base-uri`, and specify ``unix:`` followed by the path to UNIX domain socket. For example, if UNIX domain socket is ``/tmp/nghttpx.sock``, use ``--base-uri=unix:/tmp/nghttpx.sock``. h2load uses scheme, host and port in the first URI in command-line or input file. HTTP/3 ------ h2load supports HTTP/3 if it is built with HTTP/3 enabled. HTTP/3 support is experimental. In order to send HTTP/3 request, use :option:`--h3`, or specify ``h3`` to :option:`--alpn-list`. nghttp2-1.70.0/doc/sources/PaxHeaders/building-android-binary.rst0000644000000000000000000000013215232371061021722 xustar0030 mtime=1785328177.562388333 30 atime=1785328183.328518204 30 ctime=1785328204.759917976 nghttp2-1.70.0/doc/sources/building-android-binary.rst0000644000175100017510000000627215232371061022321 0ustar00runnerrunnerBuilding Android binary ======================= In this article, we briefly describe how to build Android binary using `Android NDK `_ cross-compiler on Debian Linux. The easiest way to build android binary is use Dockerfile.android. See Dockerfile.android for more details. If you cannot use Dockerfile.android for whatever reason, continue to read the rest of this article. We offer ``android-config`` script to make the build easier. To make the script work, NDK directory must be set to ``NDK`` environment variable. NDK directory is the directory where NDK is unpacked: .. code-block:: text $ unzip android-ndk-$NDK_VERSION-linux.zip $ cd android-ndk-$NDK_VERSION $ export NDK=$PWD The dependent libraries, such as OpenSSL, libev, and c-ares should be built with the same NDK toolchain and installed under ``$NDK/usr/local``. We recommend to build these libraries as static library to make the deployment easier. libxml2 support is currently disabled. Although zlib comes with Android NDK, it seems not to be a part of public API, so we have to built it for our own. That also provides us proper .pc file as a bonus. Before running ``android-config``, ``NDK`` environment variable must be set to point to the correct path. You need to set ``NGHTTP2`` environment variable to the absolute path to the source directory of nghttp2. To configure OpenSSL, use the following script: .. code-block:: sh #!/bin/sh . $NGHTTP2/android-env export ANDROID_NDK_HOME=$NDK export PATH=$TOOLCHAIN/bin:$PATH ./Configure no-shared --prefix=$PREFIX android-arm64 And run the following script to build and install without documentation: .. code-block:: sh #!/bin/sh . $NGHTTP2/android-env export PATH=$TOOLCHAIN/bin:$PATH make install_sw To configure libev, use the following script: .. code-block:: sh #!/bin/sh . $NGHTTP2/android-env ./configure \ --host=$TARGET \ --build=`dpkg-architecture -qDEB_BUILD_GNU_TYPE` \ --prefix=$PREFIX \ --disable-shared \ --enable-static \ CPPFLAGS=-I$PREFIX/include \ LDFLAGS=-L$PREFIX/lib And run ``make install`` to build and install. To configure c-ares, use the following script: .. code-block:: sh #!/bin/sh -e . $NGHTTP2/android-env ./configure \ --host=$TARGET \ --build=`dpkg-architecture -qDEB_BUILD_GNU_TYPE` \ --prefix=$PREFIX \ --disable-shared And run ``make install`` to build and install. To configure zlib, use the following script: .. code-block:: sh #!/bin/sh -e . $NGHTTP2/android-env export HOST=$TARGET ./configure \ --prefix=$PREFIX \ --libdir=$PREFIX/lib \ --includedir=$PREFIX/include \ --static And run ``make install`` to build and install. After prerequisite libraries are prepared, run ``android-config`` and then ``make`` to compile nghttp2 source files. If all went well, application binaries, such as nghttpx, are created under src directory. Strip debugging information from the binary using the following command: .. code-block:: text $ $NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/llvm-strip src/nghttpx nghttp2-1.70.0/doc/sources/PaxHeaders/tutorial-server.rst0000644000000000000000000000013215232371061020374 xustar0030 mtime=1785328177.563388338 30 atime=1785328183.329518209 30 ctime=1785328204.754540201 nghttp2-1.70.0/doc/sources/tutorial-server.rst0000644000175100017510000005407015232371061020772 0ustar00runnerrunnerTutorial: HTTP/2 server ========================= In this tutorial, we are going to write a single-threaded, event-based HTTP/2 web server, which supports HTTPS only. It can handle concurrent multiple requests, but only the GET method is supported. The complete source code, `libevent-server.c`_, is attached at the end of this page. The source also resides in the examples directory in the archive or repository. This simple server takes 3 arguments: The port number to listen on, the path to your SSL/TLS private key file, and the path to your certificate file. The synopsis is: .. code-block:: text $ libevent-server PORT /path/to/server.key /path/to/server.crt We use libevent in this tutorial to handle networking I/O. Please note that nghttp2 itself does not depend on libevent. The server starts with some libevent and OpenSSL setup in the ``main()`` and ``run()`` functions. This setup isn't specific to nghttp2, but one thing you should look at is setup of ALPN callback. The ALPN callback is used by the server to select application protocols offered by client. In ALPN, client sends the list of supported application protocols, and server selects one of them. We provide the callback for it:: static int alpn_select_proto_cb(SSL *ssl _U_, const unsigned char **out, unsigned char *outlen, const unsigned char *in, unsigned int inlen, void *arg _U_) { int rv; rv = nghttp2_select_alpn(out, outlen, in, inlen); if (rv != 1) { return SSL_TLSEXT_ERR_NOACK; } return SSL_TLSEXT_ERR_OK; } static SSL_CTX *create_ssl_ctx(const char *key_file, const char *cert_file) { SSL_CTX *ssl_ctx; EC_KEY *ecdh; ssl_ctx = SSL_CTX_new(SSLv23_server_method()); ... SSL_CTX_set_alpn_select_cb(ssl_ctx, alpn_select_proto_cb, NULL); return ssl_ctx; } In ``alpn_select_proto_cb()``, we use `nghttp2_select_alpn()` to select application protocol. The `nghttp2_select_alpn()` returns 1 only if it selected h2 (ALPN identifier for HTTP/2), and out parameters were assigned accordingly. Next, let's take a look at the main structures used by the example application: We use the ``app_context`` structure to store application-wide data:: struct app_context { SSL_CTX *ssl_ctx; struct event_base *evbase; }; We use the ``http2_session_data`` structure to store session-level (which corresponds to one HTTP/2 connection) data:: typedef struct http2_session_data { struct http2_stream_data root; struct bufferevent *bev; app_context *app_ctx; nghttp2_session *session; char *client_addr; } http2_session_data; We use the ``http2_stream_data`` structure to store stream-level data:: typedef struct http2_stream_data { struct http2_stream_data *prev, *next; char *request_path; int32_t stream_id; int fd; } http2_stream_data; A single HTTP/2 session can have multiple streams. To manage them, we use a doubly linked list: The first element of this list is pointed to by the ``root->next`` in ``http2_session_data``. Initially, ``root->next`` is ``NULL``. libevent's bufferevent structure is used to perform network I/O, with the pointer to the bufferevent stored in the ``http2_session_data`` structure. Note that the bufferevent object is kept in ``http2_session_data`` and not in ``http2_stream_data``. This is because ``http2_stream_data`` is just a logical stream multiplexed over the single connection managed by the bufferevent in ``http2_session_data``. We first create a listener object to accept incoming connections. libevent's ``struct evconnlistener`` is used for this purpose:: static void start_listen(struct event_base *evbase, const char *service, app_context *app_ctx) { int rv; struct addrinfo hints; struct addrinfo *res, *rp; memset(&hints, 0, sizeof(hints)); hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_STREAM; hints.ai_flags = AI_PASSIVE; #ifdef AI_ADDRCONFIG hints.ai_flags |= AI_ADDRCONFIG; #endif /* AI_ADDRCONFIG */ rv = getaddrinfo(NULL, service, &hints, &res); if (rv != 0) { errx(1, NULL); } for (rp = res; rp; rp = rp->ai_next) { struct evconnlistener *listener; listener = evconnlistener_new_bind( evbase, acceptcb, app_ctx, LEV_OPT_CLOSE_ON_FREE | LEV_OPT_REUSEABLE, 16, rp->ai_addr, (int)rp->ai_addrlen); if (listener) { freeaddrinfo(res); return; } } errx(1, "Could not start listener"); } We specify the ``acceptcb`` callback, which is called when a new connection is accepted:: static void acceptcb(struct evconnlistener *listener _U_, int fd, struct sockaddr *addr, int addrlen, void *arg) { app_context *app_ctx = (app_context *)arg; http2_session_data *session_data; session_data = create_http2_session_data(app_ctx, fd, addr, addrlen); bufferevent_setcb(session_data->bev, readcb, writecb, eventcb, session_data); } Here we create the ``http2_session_data`` object. The connection's bufferevent is initialized at the same time. We specify three callbacks for the bufferevent: ``readcb``, ``writecb``, and ``eventcb``. The ``eventcb()`` callback is invoked by the libevent event loop when an event (e.g. connection has been established, timeout, etc.) occurs on the underlying network socket:: static void eventcb(struct bufferevent *bev _U_, short events, void *ptr) { http2_session_data *session_data = (http2_session_data *)ptr; if (events & BEV_EVENT_CONNECTED) { const unsigned char *alpn = NULL; unsigned int alpnlen = 0; SSL *ssl; fprintf(stderr, "%s connected\n", session_data->client_addr); ssl = bufferevent_openssl_get_ssl(session_data->bev); SSL_get0_alpn_selected(ssl, &alpn, &alpnlen); if (alpn == NULL || alpnlen != 2 || memcmp("h2", alpn, 2) != 0) { fprintf(stderr, "%s h2 is not negotiated\n", session_data->client_addr); delete_http2_session_data(session_data); return; } initialize_nghttp2_session(session_data); if (send_server_connection_header(session_data) != 0 || session_send(session_data) != 0) { delete_http2_session_data(session_data); return; } return; } if (events & BEV_EVENT_EOF) { fprintf(stderr, "%s EOF\n", session_data->client_addr); } else if (events & BEV_EVENT_ERROR) { fprintf(stderr, "%s network error\n", session_data->client_addr); } else if (events & BEV_EVENT_TIMEOUT) { fprintf(stderr, "%s timeout\n", session_data->client_addr); } delete_http2_session_data(session_data); } Here we validate that HTTP/2 is negotiated, and if not, drop connection. For the ``BEV_EVENT_EOF``, ``BEV_EVENT_ERROR``, and ``BEV_EVENT_TIMEOUT`` events, we just simply tear down the connection. The ``delete_http2_session_data()`` function destroys the ``http2_session_data`` object and its associated bufferevent member. As a result, the underlying connection is closed. The ``BEV_EVENT_CONNECTED`` event is invoked when SSL/TLS handshake has completed successfully. After this we are ready to begin communicating via HTTP/2. The ``initialize_nghttp2_session()`` function initializes the nghttp2 session object and several callbacks:: static void initialize_nghttp2_session(http2_session_data *session_data) { nghttp2_session_callbacks *callbacks; nghttp2_session_callbacks_new(&callbacks); nghttp2_session_callbacks_set_send_callback2(callbacks, send_callback); nghttp2_session_callbacks_set_on_frame_recv_callback(callbacks, on_frame_recv_callback); nghttp2_session_callbacks_set_on_stream_close_callback( callbacks, on_stream_close_callback); nghttp2_session_callbacks_set_on_header_callback(callbacks, on_header_callback); nghttp2_session_callbacks_set_on_begin_headers_callback( callbacks, on_begin_headers_callback); nghttp2_session_server_new(&session_data->session, callbacks, session_data); nghttp2_session_callbacks_del(callbacks); } Since we are creating a server, we use `nghttp2_session_server_new()` to initialize the nghttp2 session object. We also setup 5 callbacks for the nghttp2 session, these are explained later. The server now begins by sending the server connection preface, which always consists of a SETTINGS frame. ``send_server_connection_header()`` configures and submits it:: static int send_server_connection_header(http2_session_data *session_data) { nghttp2_settings_entry iv[1] = { {NGHTTP2_SETTINGS_MAX_CONCURRENT_STREAMS, 100}}; int rv; rv = nghttp2_submit_settings(session_data->session, NGHTTP2_FLAG_NONE, iv, ARRLEN(iv)); if (rv != 0) { warnx("Fatal error: %s", nghttp2_strerror(rv)); return -1; } return 0; } In the example SETTINGS frame we've set SETTINGS_MAX_CONCURRENT_STREAMS to 100. `nghttp2_submit_settings()` is used to queue the frame for transmission, but note it only queues the frame for transmission, and doesn't actually send it. All functions in the ``nghttp2_submit_*()`` family have this property. To actually send the frame, `nghttp2_session_send()` should be used, as described later. Since bufferevent may buffer more than the first 24 bytes from the client, we have to process them here since libevent won't invoke callback functions for this pending data. To process the received data, we call the ``session_recv()`` function:: static int session_recv(http2_session_data *session_data) { nghttp2_ssize readlen; struct evbuffer *input = bufferevent_get_input(session_data->bev); size_t datalen = evbuffer_get_length(input); unsigned char *data = evbuffer_pullup(input, -1); readlen = nghttp2_session_mem_recv2(session_data->session, data, datalen); if (readlen < 0) { warnx("Fatal error: %s", nghttp2_strerror((int)readlen)); return -1; } if (evbuffer_drain(input, (size_t)readlen) != 0) { warnx("Fatal error: evbuffer_drain failed"); return -1; } if (session_send(session_data) != 0) { return -1; } return 0; } In this function, we feed all unprocessed but already received data to the nghttp2 session object using the `nghttp2_session_mem_recv2()` function. The `nghttp2_session_mem_recv2()` function processes the data and may both invoke the previously setup callbacks and also queue outgoing frames. To send any pending outgoing frames, we immediately call ``session_send()``. The ``session_send()`` function is defined as follows:: static int session_send(http2_session_data *session_data) { int rv; rv = nghttp2_session_send(session_data->session); if (rv != 0) { warnx("Fatal error: %s", nghttp2_strerror(rv)); return -1; } return 0; } The `nghttp2_session_send()` function serializes the frame into wire format and calls the ``send_callback()``, which is of type :type:`nghttp2_send_callback2`. The ``send_callback()`` is defined as follows:: static nghttp2_ssize send_callback(nghttp2_session *session _U_, const uint8_t *data, size_t length, int flags _U_, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; struct bufferevent *bev = session_data->bev; /* Avoid excessive buffering in server side. */ if (evbuffer_get_length(bufferevent_get_output(session_data->bev)) >= OUTPUT_WOULDBLOCK_THRESHOLD) { return NGHTTP2_ERR_WOULDBLOCK; } bufferevent_write(bev, data, length); return (nghttp2_ssize)length; } Since we use bufferevent to abstract network I/O, we just write the data to the bufferevent object. Note that `nghttp2_session_send()` continues to write all frames queued so far. If we were writing the data to a non-blocking socket directly using the ``write()`` system call in the ``send_callback()``, we'd soon receive an ``EAGAIN`` or ``EWOULDBLOCK`` error since sockets have a limited send buffer. If that happens, it's possible to return :macro:`NGHTTP2_ERR_WOULDBLOCK` to signal the nghttp2 library to stop sending further data. But here, when writing to the bufferevent, we have to regulate the amount data to buffered ourselves to avoid using huge amounts of memory. To achieve this, we check the size of the output buffer and if it reaches more than or equal to ``OUTPUT_WOULDBLOCK_THRESHOLD`` bytes, we stop writing data and return :macro:`NGHTTP2_ERR_WOULDBLOCK`. The next bufferevent callback is ``readcb()``, which is invoked when data is available to read in the bufferevent input buffer:: static void readcb(struct bufferevent *bev _U_, void *ptr) { http2_session_data *session_data = (http2_session_data *)ptr; if (session_recv(session_data) != 0) { delete_http2_session_data(session_data); return; } } In this function, we just call ``session_recv()`` to process incoming data. The third bufferevent callback is ``writecb()``, which is invoked when all data in the bufferevent output buffer has been sent:: static void writecb(struct bufferevent *bev, void *ptr) { http2_session_data *session_data = (http2_session_data *)ptr; if (evbuffer_get_length(bufferevent_get_output(bev)) > 0) { return; } if (nghttp2_session_want_read(session_data->session) == 0 && nghttp2_session_want_write(session_data->session) == 0) { delete_http2_session_data(session_data); return; } if (session_send(session_data) != 0) { delete_http2_session_data(session_data); return; } } First we check whether we should drop the connection or not. The nghttp2 session object keeps track of reception and transmission of GOAWAY frames and other error conditions as well. Using this information, the nghttp2 session object can state whether the connection should be dropped or not. More specifically, if both `nghttp2_session_want_read()` and `nghttp2_session_want_write()` return 0, the connection is no-longer required and can be closed. Since we are using bufferevent and its deferred callback option, the bufferevent output buffer may still contain pending data when the ``writecb()`` is called. To handle this, we check whether the output buffer is empty or not. If all of these conditions are met, we drop connection. Otherwise, we call ``session_send()`` to process the pending output data. Remember that in ``send_callback()``, we must not write all data to bufferevent to avoid excessive buffering. We continue processing pending data when the output buffer becomes empty. We have already described the nghttp2 callback ``send_callback()``. Let's learn about the remaining nghttp2 callbacks setup in ``initialize_nghttp2_setup()`` function. The ``on_begin_headers_callback()`` function is invoked when the reception of a header block in HEADERS or PUSH_PROMISE frame is started:: static int on_begin_headers_callback(nghttp2_session *session, const nghttp2_frame *frame, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; http2_stream_data *stream_data; if (frame->hd.type != NGHTTP2_HEADERS || frame->headers.cat != NGHTTP2_HCAT_REQUEST) { return 0; } stream_data = create_http2_stream_data(session_data, frame->hd.stream_id); nghttp2_session_set_stream_user_data(session, frame->hd.stream_id, stream_data); return 0; } We are only interested in the HEADERS frame in this function. Since the HEADERS frame has several roles in the HTTP/2 protocol, we check that it is a request HEADERS, which opens new stream. If the frame is a request HEADERS, we create a ``http2_stream_data`` object to store the stream related data. We associate the created ``http2_stream_data`` object with the stream in the nghttp2 session object using `nghttp2_set_stream_user_data()`. The ``http2_stream_data`` object can later be easily retrieved from the stream, without searching through the doubly linked list. In this example server, we want to serve files relative to the current working directory in which the program was invoked. Each header name/value pair is emitted via ``on_header_callback`` function, which is called after ``on_begin_headers_callback()``:: static int on_header_callback(nghttp2_session *session, const nghttp2_frame *frame, const uint8_t *name, size_t namelen, const uint8_t *value, size_t valuelen, uint8_t flags _U_, void *user_data _U_) { http2_stream_data *stream_data; const char PATH[] = ":path"; switch (frame->hd.type) { case NGHTTP2_HEADERS: if (frame->headers.cat != NGHTTP2_HCAT_REQUEST) { break; } stream_data = nghttp2_session_get_stream_user_data(session, frame->hd.stream_id); if (!stream_data || stream_data->request_path) { break; } if (namelen == sizeof(PATH) - 1 && memcmp(PATH, name, namelen) == 0) { size_t j; for (j = 0; j < valuelen && value[j] != '?'; ++j) ; stream_data->request_path = percent_decode(value, j); } break; } return 0; } We search for the ``:path`` header field among the request headers and store the requested path in the ``http2_stream_data`` object. In this example program, we ignore the ``:method`` header field and always treat the request as a GET request. The ``on_frame_recv_callback()`` function is invoked when a frame is fully received:: static int on_frame_recv_callback(nghttp2_session *session, const nghttp2_frame *frame, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; http2_stream_data *stream_data; switch (frame->hd.type) { case NGHTTP2_DATA: case NGHTTP2_HEADERS: /* Check that the client request has finished */ if (frame->hd.flags & NGHTTP2_FLAG_END_STREAM) { stream_data = nghttp2_session_get_stream_user_data(session, frame->hd.stream_id); /* For DATA and HEADERS frame, this callback may be called after on_stream_close_callback. Check that stream still alive. */ if (!stream_data) { return 0; } return on_request_recv(session, session_data, stream_data); } break; default: break; } return 0; } First we retrieve the ``http2_stream_data`` object associated with the stream in ``on_begin_headers_callback()`` using `nghttp2_session_get_stream_user_data()`. If the requested path cannot be served for some reason (e.g. file is not found), we send a 404 response using ``error_reply()``. Otherwise, we open the requested file and send its content. We send the header field ``:status`` as a single response header. Sending the file content is performed by the ``send_response()`` function:: static int send_response(nghttp2_session *session, int32_t stream_id, nghttp2_nv *nva, size_t nvlen, int fd) { int rv; nghttp2_data_provider2 data_prd; data_prd.source.fd = fd; data_prd.read_callback = file_read_callback; rv = nghttp2_submit_response2(session, stream_id, nva, nvlen, &data_prd); if (rv != 0) { warnx("Fatal error: %s", nghttp2_strerror(rv)); return -1; } return 0; } nghttp2 uses the :type:`nghttp2_data_provider2` structure to send the entity body to the remote peer. The ``source`` member of this structure is a union, which can be either a void pointer or an int (which is intended to be used as file descriptor). In this example server, we use it as a file descriptor. We also set the ``file_read_callback()`` callback function to read the contents of the file:: static nghttp2_ssize file_read_callback(nghttp2_session *session _U_, int32_t stream_id _U_, uint8_t *buf, size_t length, uint32_t *data_flags, nghttp2_data_source *source, void *user_data _U_) { int fd = source->fd; ssize_t r; while ((r = read(fd, buf, length)) == -1 && errno == EINTR) ; if (r == -1) { return NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE; } if (r == 0) { *data_flags |= NGHTTP2_DATA_FLAG_EOF; } return (nghttp2_ssize)r; } If an error occurs while reading the file, we return :macro:`NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. This tells the library to send RST_STREAM to the stream. When all data has been read, the :macro:`NGHTTP2_DATA_FLAG_EOF` flag is set to signal nghttp2 that we have finished reading the file. The `nghttp2_submit_response2()` function is used to send the response to the remote peer. The ``on_stream_close_callback()`` function is invoked when the stream is about to close:: static int on_stream_close_callback(nghttp2_session *session, int32_t stream_id, uint32_t error_code _U_, void *user_data) { http2_session_data *session_data = (http2_session_data *)user_data; http2_stream_data *stream_data; stream_data = nghttp2_session_get_stream_user_data(session, stream_id); if (!stream_data) { return 0; } remove_stream(session_data, stream_data); delete_http2_stream_data(stream_data); return 0; } Lastly, we destroy the ``http2_stream_data`` object in this function, since the stream is about to close and we no longer need the object. nghttp2-1.70.0/doc/sources/PaxHeaders/contribute.rst0000644000000000000000000000013215232371061017403 xustar0030 mtime=1785328177.562956667 30 atime=1785328183.328518204 30 ctime=1785328204.761306972 nghttp2-1.70.0/doc/sources/contribute.rst0000644000175100017510000000453215232371061017777 0ustar00runnerrunnerContribution Guidelines ======================= [This text was composed based on 1.2. License section of curl/libcurl project.] When contributing with code, you agree to put your changes and new code under the same license nghttp2 is already using unless stated and agreed otherwise. When changing existing source code, you do not alter the copyright of the original file(s). The copyright will still be owned by the original creator(s) or those who have been assigned copyright by the original author(s). By submitting a patch to the nghttp2 project, you are assumed to have the right to the code and to be allowed by your employer or whatever to hand over that patch/code to us. We will credit you for your changes as far as possible, to give credit but also to keep a trace back to who made what changes. Please always provide us with your full real name when contributing! Coding style ------------ We use clang-format to format source code consistently. The clang-format configuration file .clang-format is located at the root directory. Since clang-format produces slightly different results between versions, we currently use clang-format-19. To detect any violation to the coding style, we recommend to setup git pre-commit hook to check coding style of the changes you introduced. The pre-commit file is located at the root directory. Copy it under .git/hooks and make sure that it is executable. The pre-commit script uses clang-format-diff.py to detect any style errors. If it is not in your PATH or it exists under different name (e.g., clang-format-diff-18 in debian), either add it to PATH variable or add git option ``clangformatdiff.binary`` to point to the script. For emacs users, integrating clang-format to emacs is very easy. clang-format.el should come with clang distribution. If it is not found, download it from `here `_. And add these lines to your .emacs file: .. code-block:: lisp ;; From ;; https://code.google.com/p/chromium/wiki/Emacs#Use_Google's_C++_style! (load "//clang-format.el") (add-hook 'c-mode-common-hook (function (lambda () (local-set-key (kbd "TAB") 'clang-format-region)))) You can find other editor integration in http://clang.llvm.org/docs/ClangFormat.html. nghttp2-1.70.0/doc/sources/PaxHeaders/tutorial-hpack.rst0000644000000000000000000000013215232371061020154 xustar0030 mtime=1785328177.562956667 30 atime=1785328183.328518204 30 ctime=1785328204.755883207 nghttp2-1.70.0/doc/sources/tutorial-hpack.rst0000644000175100017510000001307015232371061020545 0ustar00runnerrunnerTutorial: HPACK API =================== In this tutorial, we describe basic use of nghttp2's HPACK API. We briefly describe the APIs for deflating and inflating header fields. The full example of using these APIs, `deflate.c`_, is attached at the end of this page. It also resides in the examples directory in the archive or repository. Deflating (encoding) headers ---------------------------- First we need to initialize a :type:`nghttp2_hd_deflater` object using the `nghttp2_hd_deflate_new()` function:: int nghttp2_hd_deflate_new(nghttp2_hd_deflater **deflater_ptr, size_t deflate_hd_table_bufsize_max); This function allocates a :type:`nghttp2_hd_deflater` object, initializes it, and assigns its pointer to ``*deflater_ptr``. The *deflate_hd_table_bufsize_max* is the upper bound of header table size the deflater will use. This will limit the memory usage by the deflater object for the dynamic header table. If in doubt, just specify 4096 here, which is the default upper bound of dynamic header table buffer size. To encode header fields, use the `nghttp2_hd_deflate_hd2()` function:: nghttp2_ssize nghttp2_hd_deflate_hd2(nghttp2_hd_deflater *deflater, uint8_t *buf, size_t buflen, const nghttp2_nv *nva, size_t nvlen); The *deflater* is the deflater object initialized by `nghttp2_hd_deflate_new()` described above. The encoded byte string is written to the buffer *buf*, which has length *buflen*. The *nva* is a pointer to an array of headers fields, each of type :type:`nghttp2_nv`. *nvlen* is the number of header fields which *nva* contains. It is important to initialize and assign all members of :type:`nghttp2_nv`. For security sensitive header fields (such as cookies), set the :macro:`NGHTTP2_NV_FLAG_NO_INDEX` flag in :member:`nghttp2_nv.flags`. Setting this flag prevents recovery of sensitive header fields by compression based attacks: This is achieved by not inserting the header field into the dynamic header table. `nghttp2_hd_deflate_hd2()` processes all headers given in *nva*. The *nva* must include all request or response header fields to be sent in one HEADERS (or optionally following (multiple) CONTINUATION frame(s)). The *buf* must have enough space to store the encoded result, otherwise the function will fail. To estimate the upper bound of the encoded result length, use `nghttp2_hd_deflate_bound()`:: size_t nghttp2_hd_deflate_bound(nghttp2_hd_deflater *deflater, const nghttp2_nv *nva, size_t nvlen); Pass this function the same parameters (*deflater*, *nva*, and *nvlen*) which will be passed to `nghttp2_hd_deflate_hd2()`. Subsequent calls to `nghttp2_hd_deflate_hd2()` will use the current encoder state and perform differential encoding, which yields HPAC's fundamental compression gain. If `nghttp2_hd_deflate_hd2()` fails, the failure is fatal and any further calls with the same deflater object will fail. Thus it's very important to use `nghttp2_hd_deflate_bound()` to determine the required size of the output buffer. To delete a :type:`nghttp2_hd_deflater` object, use the `nghttp2_hd_deflate_del()` function. Inflating (decoding) headers ---------------------------- A :type:`nghttp2_hd_inflater` object is used to inflate compressed header data. To initialize the object, use `nghttp2_hd_inflate_new()`:: int nghttp2_hd_inflate_new(nghttp2_hd_inflater **inflater_ptr); To inflate header data, use `nghttp2_hd_inflate_hd3()`:: nghttp2_ssize nghttp2_hd_inflate_hd3(nghttp2_hd_inflater *inflater, nghttp2_nv *nv_out, int *inflate_flags, const uint8_t *in, size_t inlen, int in_final); `nghttp2_hd_inflate_hd3()` reads a stream of bytes and outputs a single header field at a time. Multiple calls are normally required to read a full stream of bytes and output all of the header fields. The *inflater* is the inflater object initialized above. The *nv_out* is a pointer to a :type:`nghttp2_nv` into which one header field may be stored. The *in* is a pointer to input data, and *inlen* is its length. The caller is not required to specify the whole deflated header data via *in* at once: Instead it can call this function multiple times as additional data bytes become available. If *in_final* is nonzero, it tells the function that the passed data is the final sequence of deflated header data. The *inflate_flags* is an output parameter; on success the function sets it to a bitset of flags. It will be described later. This function returns when each header field is inflated. When this happens, the function sets the :macro:`NGHTTP2_HD_INFLATE_EMIT` flag in *inflate_flags*, and a header field is stored in *nv_out*. The return value indicates the number of bytes read from *in* processed so far, which may be less than *inlen*. The caller should call the function repeatedly until all bytes are processed. Processed bytes should be removed from *in*, and *inlen* should be adjusted appropriately. If *in_final* is nonzero and all given data was processed, the function sets the :macro:`NGHTTP2_HD_INFLATE_FINAL` flag in *inflate_flags*. When you see this flag set, call the `nghttp2_hd_inflate_end_headers()` function. If *in_final* is zero and the :macro:`NGHTTP2_HD_INFLATE_EMIT` flag is not set, it indicates that all given data was processed. The caller is required to pass additional data. Example usage of `nghttp2_hd_inflate_hd3()` is shown in the `inflate_header_block()` function in `deflate.c`_. Finally, to delete a :type:`nghttp2_hd_inflater` object, use `nghttp2_hd_inflate_del()`. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_session_mem_send2.rst0000644000000000000000000000013215232371110020617 xustar0030 mtime=1785328200.990667505 30 atime=1785328201.229965013 30 ctime=1785328204.688195592 nghttp2-1.70.0/doc/nghttp2_session_mem_send2.rst0000644000175100017510000000321215232371110021205 0ustar00runnerrunner nghttp2_session_mem_send2 ========================= Synopsis -------- *#include * .. function:: nghttp2_ssize nghttp2_session_mem_send2(nghttp2_session *session, const uint8_t **data_ptr) Returns the serialized data to send. This function behaves like `nghttp2_session_send()` except that it does not use :type:`nghttp2_send_callback2` to transmit data. Instead, it assigns the pointer to the serialized data to the *\*data_ptr* and returns its length. The other callbacks are called in the same way as they are in `nghttp2_session_send()`. If no data is available to send, this function returns 0. This function may not return all serialized data in one invocation. To get all data, call this function repeatedly until it returns 0 or one of negative error codes. The assigned *\*data_ptr* is valid until the next call of `nghttp2_session_mem_send2()` or `nghttp2_session_send()`. The caller must send all data before sending the next chunk of data. This function returns the length of the data pointed by the *\*data_ptr* if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. .. note:: This function may produce very small byte string. If that is the case, and application disables Nagle algorithm (``TCP_NODELAY``), then writing this small chunk leads to very small packet, and it is very inefficient. An application should be responsible to buffer up small chunks of data as necessary to avoid this situation. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_session_get_next_stream_id.rst0000644000000000000000000000013215232371110022612 xustar0030 mtime=1785328200.989976149 30 atime=1785328201.209249268 30 ctime=1785328204.668103262 nghttp2-1.70.0/doc/nghttp2_session_get_next_stream_id.rst0000644000175100017510000000057115232371110023205 0ustar00runnerrunner nghttp2_session_get_next_stream_id ================================== Synopsis -------- *#include * .. function:: uint32_t nghttp2_session_get_next_stream_id(nghttp2_session *session) Returns the next outgoing stream ID.

GENERATED by help2rst.py. DO NOT EDIT DIRECTLY. .. program:: nghttpx nghttpx(1) ========== SYNOPSIS -------- **nghttpx** [OPTIONS]... [ ] DESCRIPTION ----------- A reverse proxy for HTTP/3, HTTP/2, and HTTP/1. .. describe:: Set path to server's private key. Required unless "no-tls" parameter is used in :option:`--frontend` option. .. describe:: Set path to server's certificate. Required unless "no-tls" parameter is used in :option:`--frontend` option. OPTIONS ------- The options are categorized into several groups. Connections ~~~~~~~~~~~ .. option:: -b, --backend=(,|unix:)[;[[:...]][[;]...] Set backend host and port. The multiple backend addresses are accepted by repeating this option. UNIX domain socket can be specified by prefixing path name with "unix:" (e.g., unix:/var/run/backend.sock). Optionally, if s are given, the backend address is only used if request matches the pattern. The pattern matching is closely designed to ServeMux in net/http package of Go programming language. consists of path, host + path or just host. The path must start with "*/*". If it ends with "*/*", it matches all request path in its subtree. To deal with the request to the directory without trailing slash, the path which ends with "*/*" also matches the request path which only lacks trailing '*/*' (e.g., path "*/foo/*" matches request path "*/foo*"). If it does not end with "*/*", it performs exact match against the request path. If host is given, it performs a match against the request host. For a request received on the frontend listener with "sni-fwd" parameter enabled, SNI host is used instead of a request host. If host alone is given, "*/*" is appended to it, so that it matches all request paths under the host (e.g., specifying "nghttp2.org" equals to "nghttp2.org/"). CONNECT method is treated specially. It does not have path, and we don't allow empty path. To workaround this, we assume that CONNECT method has "*/*" as path. Patterns with host take precedence over patterns with just path. Then, longer patterns take precedence over shorter ones. Host can include "\*" in the left most position to indicate wildcard match (only suffix match is done). The "\*" must match at least one character. For example, host pattern "\*.nghttp2.org" matches against "www.nghttp2.org" and "git.ngttp2.org", but does not match against "nghttp2.org". The exact hosts match takes precedence over the wildcard hosts match. If path part ends with "\*", it is treated as wildcard path. The wildcard path behaves differently from the normal path. For normal path, match is made around the boundary of path component separator,"*/*". On the other hand, the wildcard path does not take into account the path component separator. All paths which include the wildcard path without last "\*" as prefix, and are strictly longer than wildcard path without last "\*" are matched. "\*" must match at least one character. For example, the pattern "*/foo\**" matches "*/foo/*" and "*/foobar*". But it does not match "*/foo*", or "*/fo*". If is omitted or empty string, "*/*" is used as pattern, which matches all request paths (catch-all pattern). The catch-all backend must be given. When doing a match, nghttpx made some normalization to pattern, request host and path. For host part, they are converted to lower case. For path part, percent-encoded unreserved characters defined in RFC 3986 are decoded, and any dot-segments (".." and ".") are resolved and removed. For example, :option:`-b`\'127.0.0.1,8080;nghttp2.org/httpbin/' matches the request host "nghttp2.org" and the request path "*/httpbin/get*", but does not match the request host "nghttp2.org" and the request path "*/index.html*". The multiple s can be specified, delimiting them by ":". Specifying :option:`-b`\'127.0.0.1,8080;nghttp2.org:www.nghttp2.org' has the same effect to specify :option:`-b`\'127.0.0.1,8080;nghttp2.org' and :option:`-b`\'127.0.0.1,8080;www.nghttp2.org'. The backend addresses sharing same are grouped together forming load balancing group. Several parameters are accepted after . The parameters are delimited by ";". The available parameters are: "proto=", "tls", "sni=", "fall=", "rise=", "affinity=", "dns", "redirect-if-not-tls", "upgrade-scheme", "mruby=", "read-timeout=", "write-timeout=", "group=", "group-weight=", "weight=", and "dnf". The parameter consists of keyword, and optionally followed by "=" and value. For example, the parameter "proto=h2" consists of the keyword "proto" and value "h2". The parameter "tls" consists of the keyword "tls" without value. Each parameter is described as follows. The backend application protocol can be specified using optional "proto" parameter, and in the form of "proto=". should be one of the following list without quotes: "h2", "http/1.1". The default value of is "http/1.1". Note that usually "h2" refers to HTTP/2 over TLS. But in this option, it may mean HTTP/2 over cleartext TCP unless "tls" keyword is used (see below). TLS can be enabled by specifying optional "tls" parameter. TLS is not enabled by default. With "sni=" parameter, it can override the TLS SNI field value with given . This will default to the backend name The feature to detect whether backend is online or offline can be enabled using optional "fall" and "rise" parameters. Using "fall=" parameter, if nghttpx cannot connect to a this backend times in a row, this backend is assumed to be offline, and it is excluded from load balancing. If is 0, this backend never be excluded from load balancing whatever times nghttpx cannot connect to it, and this is the default. There is also "rise=" parameter. After backend was excluded from load balancing group, nghttpx periodically attempts to make a connection to the failed backend, and if the connection is made successfully times in a row, the backend is assumed to be online, and it is now eligible for load balancing target. If is 0, a backend is permanently offline, once it goes in that state, and this is the default behaviour. The session affinity is enabled using "affinity=" parameter. If "ip" is given in , client IP based session affinity is enabled. If "cookie" is given in , cookie based session affinity is enabled. If "none" is given in , session affinity is disabled, and this is the default. The session affinity is enabled per . If at least one backend has "affinity" parameter, and its is not "none", session affinity is enabled for all backend servers sharing the same . It is advised to set "affinity" parameter to all backend explicitly if session affinity is desired. The session affinity may break if one of the backend gets unreachable, or backend settings are reloaded or replaced by API. If "affinity=cookie" is used, the additional configuration is required. "affinity-cookie-name=" must be used to specify a name of cookie to use. Optionally, "affinity-cookie-path=" can be used to specify a path which cookie is applied. The optional "affinity-cookie-secure=" controls the Secure attribute of a cookie. The default value is "auto", and the Secure attribute is determined by a request scheme. If a request scheme is "https", then Secure attribute is set. Otherwise, it is not set. If is "yes", the Secure attribute is always set. If is "no", the Secure attribute is always omitted. "affinity-cookie-stickiness=" controls stickiness of this affinity. If is "loose", removing or adding a backend server might break the affinity and the request might be forwarded to a different backend server. If is "strict", removing the designated backend server breaks affinity, but adding new backend server does not cause breakage. If the designated backend server becomes unavailable, new backend server is chosen as if the request does not have an affinity cookie. defaults to "loose". By default, name resolution of backend host name is done at start up, or reloading configuration. If "dns" parameter is given, name resolution takes place dynamically. This is useful if backend address changes frequently. If "dns" is given, name resolution of backend host name at start up, or reloading configuration is skipped. If "redirect-if-not-tls" parameter is used, the matched backend requires that frontend connection is TLS encrypted. If it isn't, nghttpx responds to the request with 308 status code, and https URI the client should use instead is included in Location header field. The port number in redirect URI is 443 by default, and can be changed using :option:`--redirect-https-port` option. If at least one backend has "redirect-if-not-tls" parameter, this feature is enabled for all backend servers sharing the same . It is advised to set "redirect-if-no-tls" parameter to all backends explicitly if this feature is desired. If "upgrade-scheme" parameter is used along with "tls" parameter, HTTP/2 :scheme pseudo header field is changed to "https" from "http" when forwarding a request to this particular backend. This is a workaround for a backend server which requires "https" :scheme pseudo header field on TLS encrypted connection. "mruby=" parameter specifies a path to mruby script file which is invoked when this pattern is matched. All backends which share the same pattern must have the same mruby path. "read-timeout=" and "write-timeout=" parameters specify the read and write timeout of the backend connection when this pattern is matched. All backends which share the same pattern must have the same timeouts. If these timeouts are entirely omitted for a pattern, :option:`--backend-read-timeout` and :option:`--backend-write-timeout` are used. "group=" parameter specifies the name of group this backend address belongs to. By default, it belongs to the unnamed default group. The name of group is unique per pattern. "group-weight=" parameter specifies the weight of the group. The higher weight gets more frequently selected by the load balancing algorithm. must be [1, 256] inclusive. The weight 8 has 4 times more weight than 2. must be the same for all addresses which share the same . If "group-weight" is omitted in an address, but the other address which belongs to the same group specifies "group-weight", its weight is used. If no "group-weight" is specified for all addresses, the weight of a group becomes 1. "group" and "group-weight" are ignored if session affinity is enabled. "weight=" parameter specifies the weight of the backend address inside a group which this address belongs to. The higher weight gets more frequently selected by the load balancing algorithm. must be [1, 256] inclusive. The weight 8 has 4 times more weight than weight 2. If this parameter is omitted, weight becomes 1. "weight" is ignored if session affinity is enabled. If "dnf" parameter is specified, an incoming request is not forwarded to a backend and just consumed along with the request body (actually a backend server never be contacted). It is expected that the HTTP response is generated by mruby script (see "mruby=" parameter above). "dnf" is an abbreviation of "do not forward". Since ";" and ":" are used as delimiter, must not contain these characters. In order to include ":" in , one has to specify "%3A" (which is percent-encoded from of ":") instead. Since ";" has special meaning in shell, the option value must be quoted. Default: ``127.0.0.1,80`` .. option:: -f, --frontend=(,|unix:)[[;]...] Set frontend host and port. If is '\*', it assumes all addresses including both IPv4 and IPv6. UNIX domain socket can be specified by prefixing path name with "unix:" (e.g., unix:/var/run/nghttpx.sock). This option can be used multiple times to listen to multiple addresses. This option can take 0 or more parameters, which are described below. Note that "api" and "healthmon" parameters are mutually exclusive. Optionally, TLS can be disabled by specifying "no-tls" parameter. TLS is enabled by default. If "sni-fwd" parameter is used, when performing a match to select a backend server, SNI host name received from the client is used instead of the request host. See :option:`--backend` option about the pattern match. To make this frontend as API endpoint, specify "api" parameter. This is disabled by default. It is important to limit the access to the API frontend. Otherwise, someone may change the backend server, and break your services, or expose confidential information to the outside the world. To make this frontend as health monitor endpoint, specify "healthmon" parameter. This is disabled by default. Any requests which come through this address are replied with 200 HTTP status, without no body. To accept PROXY protocol version 1 and 2 on frontend connection, specify "proxyproto" parameter. This is disabled by default. To receive HTTP/3 (QUIC) traffic, specify "quic" parameter. It makes nghttpx listen on UDP port rather than TCP port. UNIX domain socket, "api", and "healthmon" parameters cannot be used with "quic" parameter. Default: ``*,3000`` .. option:: --backlog= Set listen backlog size. Default: ``65536`` .. option:: --backend-address-family=(auto|IPv4|IPv6) Specify address family of backend connections. If "auto" is given, both IPv4 and IPv6 are considered. If "IPv4" is given, only IPv4 address is considered. If "IPv6" is given, only IPv6 address is considered. Default: ``auto`` .. option:: --backend-http-proxy-uri= Specify proxy URI in the form http://[:@]:. If a proxy requires authentication, specify and . Note that they must be properly percent-encoded. This proxy is used when the backend connection is HTTP/2. First, make a CONNECT request to the proxy and it connects to the backend on behalf of nghttpx. This forms tunnel. After that, nghttpx performs SSL/TLS handshake with the downstream through the tunnel. The timeouts when connecting and making CONNECT request can be specified by :option:`--backend-read-timeout` and :option:`--backend-write-timeout` options. Performance ~~~~~~~~~~~ .. option:: -n, --workers= Set the number of worker threads. Default: ``1`` .. option:: --single-thread Run everything in one thread inside the worker process. This feature is provided for better debugging experience, or for the platforms which lack thread support.

This is used when doing health check against offline backend (see "fail" parameter in :option:`--backend` option). It is also used to limit the maximum interval to temporarily disable backend when nghttpx failed to connect to it. These intervals are calculated using exponential backoff, and consecutive failed attempts increase the interval. This option caps its maximum value. Default: ``2m`` .. option:: --frontend-min-write-rate= Set the minimum rate of stream data that client must read from frontend connection. The specifies the number of bytes per second. If client is unable to read at least the given rate, the connection is closed. The implementation extends the timeout by the stream data to send.

It is used in backend TLS connections to verify peer's certificate. The file must be in PEM format. It can contain multiple certificates. If the linked OpenSSL is configured to load system wide certificates, they are loaded at startup regardless of this option. .. option:: --private-key-passwd-file= Path to file that contains password for the server's private key. If none is given and the private key is password protected it'll be requested interactively. .. option:: --subcert=:[[;]...] Specify additional certificate and private key file. nghttpx will choose certificates based on the hostname indicated by client using TLS SNI extension. If nghttpx is built with OpenSSL >= 1.0.2, the signature algorithms (e.g., ECDSA+SHA256) presented by client are also taken into consideration. This allows nghttpx to send ML-DSA or ECDSA certificate to modern clients, while sending RSA based certificate to older clients. This option can be used multiple times. Additional parameter can be specified in . The available is "sct-dir=". "sct-dir=" specifies the path to directory which contains \*.sct files for TLS signed_certificate_timestamp extension (RFC 6962). This feature requires OpenSSL >= 1.0.2. See also :option:`--tls-sct-dir` option. .. option:: --dh-param-file= Path to file that contains DH parameters in PEM format. Without this option, DHE cipher suites are not available. .. option:: --alpn-list= Comma delimited list of ALPN protocol identifier sorted in the order of preference. That means most desirable protocol comes first. The parameter must be delimited by a single comma only and any white spaces are treated as a part of protocol string. Default: ``h2,http/1.1`` .. option:: --verify-client Require and verify client certificate. .. option:: --verify-client-cacert= Path to file that contains CA certificates to verify client certificate. The file must be in PEM format. It can contain multiple certificates. .. option:: --verify-client-tolerate-expired Accept expired client certificate.

If several files are given, only the first key is used to encrypt TLS session tickets. Other keys are accepted but server will issue new session ticket with first key. This allows session key rotation. Please note that key rotation does not occur automatically. User should rearrange files or change options values and restart nghttpx gracefully. If opening or reading given file fails, all loaded keys are discarded and it is treated as if none of this option is given. If this option is not given or an error occurred while opening or reading a file, key is generated every 1 hour internally and they are valid for 12 hours. This is recommended if ticket key sharing between nghttpx instances is not required. .. option:: --tls-ticket-key-memcached=,[;tls] Specify address of memcached server to get TLS ticket keys for session resumption. This enables shared TLS ticket key between multiple nghttpx instances. nghttpx does not set TLS ticket key to memcached. The external ticket key generator is required. nghttpx just gets TLS ticket keys from memcached, and use them, possibly replacing current set of keys. It is up to extern TLS ticket key generator to rotate keys frequently. See "TLS SESSION TICKET RESUMPTION" section in manual page to know the data format in memcached entry. Optionally, memcached connection can be encrypted with TLS by specifying "tls" parameter. .. option:: --tls-ticket-key-memcached-address-family=(auto|IPv4|IPv6) Specify address family of memcached connections to get TLS ticket keys.

By default, aes-128-cbc is used. .. option:: --tls-ticket-key-memcached-cert-file= Path to client certificate for memcached connections to get TLS ticket keys. .. option:: --tls-ticket-key-memcached-private-key-file= Path to client private key for memcached connections to get TLS ticket keys. .. option:: --tls-dyn-rec-warmup-threshold= Specify the threshold size for TLS dynamic record size behaviour. During a TLS session, after the threshold number of bytes have been written, the TLS record size will be increased to the maximum allowed (16K). The max record size will continue to be used on the active TLS session. After :option:`--tls-dyn-rec-idle-timeout` has elapsed, the record size is reduced to 1300 bytes. Specify 0 to always use the maximum record size, regardless of idle period. This behaviour applies to all TLS based frontends, and TLS HTTP/2 backends. Default: ``1M`` .. option:: --tls-dyn-rec-idle-timeout= Specify TLS dynamic record size behaviour timeout. See :option:`--tls-dyn-rec-warmup-threshold` for more information. This behaviour applies to all TLS based frontends, and TLS HTTP/2 backends. Default: ``1s`` .. option:: --no-http2-cipher-block-list Allow block listed cipher suite on frontend HTTP/2 connection. See https://tools.ietf.org/html/rfc7540#appendix-A for the complete HTTP/2 cipher suites block list. .. option:: --client-no-http2-cipher-block-list Allow block listed cipher suite on backend HTTP/2 connection. See https://tools.ietf.org/html/rfc7540#appendix-A for the complete HTTP/2 cipher suites block list. .. option:: --tls-sct-dir= Specifies the directory where \*.sct files exist. All \*.sct files in are read, and sent as extension_data of TLS signed_certificate_timestamp (RFC 6962) to client. These \*.sct files are for the certificate specified in positional command-line argument , or certificate option in configuration file. For additional certificates, use :option:`--subcert` option. This option requires OpenSSL >= 1.0.2. .. option:: --psk-secrets= Read list of PSK identity and secrets from . This is used for frontend connection. The each line of input file is formatted as :, where is PSK identity, and is secret in hex. An empty line, and line which starts with '#' are skipped. The default enabled cipher list might not contain any PSK cipher suite. In that case, desired PSK cipher suites must be enabled using :option:`--ciphers` option. The desired PSK cipher suite may be block listed by HTTP/2. To use those cipher suites with HTTP/2, consider to use :option:`--no-http2-cipher-block-list` option. But be aware its implications. .. option:: --client-psk-secrets= Read PSK identity and secrets from . This is used for backend connection. The each line of input file is formatted as :, where is PSK identity, and is secret in hex. An empty line, and line which starts with '#' are skipped. The first identity and secret pair encountered is used. The default enabled cipher list might not contain any PSK cipher suite. In that case, desired PSK cipher suites must be enabled using :option:`--client-ciphers` option. The desired PSK cipher suite may be block listed by HTTP/2. To use those cipher suites with HTTP/2, consider to use :option:`--client-no-http2-cipher-block-list` option. But be aware its implications. .. option:: --tls-no-postpone-early-data By default, except for QUIC connections, nghttpx postpones forwarding HTTP requests sent in early data, including those sent in partially in it, until TLS handshake finishes. If all backend server recognizes "Early-Data" header field, using this option makes nghttpx not postpone forwarding request and get full potential of 0-RTT data. .. option:: --tls-max-early-data= Sets the maximum amount of 0-RTT data that server accepts. Default: ``16K`` .. option:: --tls-ktls Enable ktls. .. option:: --ech-config-file= Read Encrypted Client Hello (ECH) server configuration from .

Specify 0 to disable padding. This option is meant for debugging purpose and not intended to enhance protocol security. .. option:: --no-server-push Disable HTTP/2 server push. Server push is supported by default mode and HTTP/2 frontend via Link header field. It is also supported if both frontend and backend are HTTP/2 in default mode. In this case, server push from backend session is relayed to frontend, and server push via Link header field is also supported. .. option:: --frontend-http2-optimize-write-buffer-size (Experimental) Enable write buffer size optimization in frontend HTTP/2 TLS connection. This optimization aims to reduce write buffer size so that it only contains bytes which can send immediately. This makes server more responsive to prioritized HTTP/2 stream because the buffering of lower priority stream is reduced. This option is only effective on recent Linux platform. .. option:: --frontend-http2-optimize-window-size (Experimental) Automatically tune connection level window size of frontend HTTP/2 TLS connection. If this feature is enabled, connection window size starts with the default window size, 65535 bytes. nghttpx automatically adjusts connection window size based on TCP receiving window size.

When :option:`--http2-proxy` is used, these headers will not be altered regardless of this option. .. option:: --redirect-https-port= Specify the port number which appears in Location header field when redirect to HTTPS URI is made due to "redirect-if-not-tls" parameter in :option:`--backend` option. Default: ``443`` .. option:: --require-http-scheme Always require http or https scheme in HTTP request. It also requires that https scheme must be used for an encrypted connection. Otherwise, http scheme must be used. This option is recommended for a server deployment which directly faces clients and the services it provides only require http or https scheme. API ~~~ .. option:: --api-max-request-body= Set the maximum size of request body for API request. Default: ``32M`` DNS ~~~ .. option:: --dns-cache-timeout= Set duration that cached DNS results remain valid. Note that nghttpx caches the unsuccessful results as well. Default: ``10s`` .. option:: --dns-lookup-timeout= Set timeout that DNS server is given to respond to the initial DNS query. For the 2nd and later queries, server is given time based on this timeout, and it is scaled linearly. Default: ``250ms`` .. option:: --dns-max-try= Set the number of DNS query before nghttpx gives up name lookup. Default: ``3`` .. option:: --frontend-max-requests= The number of requests that single frontend connection can process. For HTTP/2, this is the number of streams in one HTTP/2 connection. For HTTP/1, this is the number of keep alive requests. This is hint to nghttpx, and it may allow additional few requests. The default value is unlimited. Debug ~~~~~ .. option:: --frontend-http2-dump-request-header= Dumps request headers received by HTTP/2 frontend to the file denoted in . The output is done in HTTP/1 header field format and each header block is followed by an empty line. This option is not thread safe and MUST NOT be used with option :option:`-n`\, where >= 2. .. option:: --frontend-http2-dump-response-header= Dumps response headers sent from HTTP/2 frontend to the file denoted in . The output is done in HTTP/1 header field format and each header block is followed by an empty line. This option is not thread safe and MUST NOT be used with option :option:`-n`\, where >= 2. .. option:: -o, --frontend-frame-debug Print HTTP/2 frames in frontend to stderr. This option is not thread safe and MUST NOT be used with option :option:`-n`\=N, where N >= 2. Process ~~~~~~~ .. option:: -D, --daemon Run in a background. If :option:`-D` is used, the current working directory is changed to '*/*'. .. option:: --pid-file= Set path to save PID of this program. .. option:: --user= Run this program as . This option is intended to be used to drop root privileges. .. option:: --single-process Run this program in a single process mode for debugging purpose. Without this option, nghttpx creates at least 2 processes: main and worker processes. If this option is used, main and worker are unified into a single process. nghttpx still spawns additional process if neverbleed is used. In the single process mode, the signal handling feature is disabled. .. option:: --max-worker-processes= The maximum number of worker processes. nghttpx spawns new worker process when it reloads its configuration. The previous worker process enters graceful termination period and will terminate when it finishes handling the existing connections. However, if reloading configurations happen very frequently, the worker processes might be piled up if they take a bit long time to finish the existing connections. With this option, if the number of worker processes exceeds the given value, the oldest worker process is terminated immediately. Specifying 0 means no limit and it is the default behaviour. .. option:: --worker-process-grace-shutdown-period= Maximum period for a worker process to terminate gracefully. When a worker process enters in graceful shutdown period (e.g., when nghttpx reloads its configuration) and it does not finish handling the existing connections in the given period of time, it is immediately terminated. Specifying 0 means no limit and it is the default behaviour. Scripting ~~~~~~~~~ .. option:: --mruby-file= Set mruby script file .. option:: --ignore-per-pattern-mruby-error Ignore mruby compile error for per-pattern mruby script file. If error occurred, it is treated as if no mruby file were specified for the pattern. HTTP/3 and QUIC ~~~~~~~~~~~~~~~ .. option:: --frontend-quic-idle-timeout= Specify an idle timeout for QUIC connection. Default: ``30s`` .. option:: --frontend-quic-debug-log Output QUIC debug log to */dev/stderr.* .. option:: --quic-bpf-program-file= Specify a path to eBPF program file reuseport_kern.o to direct an incoming QUIC UDP datagram to a correct socket. Default: ``/usr/local/lib/nghttp2/reuseport_kern.o`` .. option:: --frontend-quic-early-data Enable early data on frontend QUIC connections. nghttpx sends "Early-Data" header field to a backend server if a request is received in early data and handshake has not finished. All backend servers should deal with possibly replayed requests. .. option:: --frontend-quic-qlog-dir= Specify a directory where a qlog file is written for frontend QUIC connections. A qlog file is created per each QUIC connection. The file name is ISO8601 basic format, followed by "-", server Source Connection ID and ".sqlog". .. option:: --frontend-quic-require-token Require an address validation token for a frontend QUIC connection. Server sends a token in Retry packet or NEW_TOKEN frame in the previous connection. .. option:: --frontend-quic-congestion-controller= Specify a congestion controller algorithm for a frontend QUIC connection. should be either "cubic" or "bbr". Default: ``cubic`` .. option:: --frontend-quic-secret-file= Path to file that contains secure random data to be used as QUIC keying materials. It is used to derive keys for encrypting tokens and Connection IDs. It is not used to encrypt QUIC packets. Each line of this file must contain exactly 136 bytes hex-encoded string (when decoded the byte string is 68 bytes long). The first 3 bits of decoded byte string are used to identify the keying material. An empty line or a line which starts '#' is ignored. The file can contain more than one keying materials. Because the identifier is 3 bits, at most 8 keying materials are read and the remaining data is discarded. The first keying material in the file is primarily used for encryption and decryption for new connection. The other ones are used to decrypt data for the existing connections. Specifying multiple keying materials enables key rotation. Please note that key rotation does not occur automatically. User should update files or change options values and restart nghttpx gracefully. If opening or reading given file fails, all loaded keying materials are discarded and it is treated as if none of this option is given. If this option is not given or an error occurred while opening or reading a file, a keying material is generated internally on startup and reload. .. option:: --quic-server-id= Specify server ID encoded in Connection ID to identify this particular server instance. Connection ID is encrypted and this part is not visible in public. It must be 4 bytes long and must be encoded in hex string (which is 8 bytes long). If this option is omitted, a random server ID is generated on startup and configuration reload. .. option:: --frontend-quic-initial-rtt= Specify the initial RTT of the frontend QUIC connection. Default: ``333ms`` .. option:: --no-quic-bpf Disable eBPF. .. option:: --frontend-http3-window-size= Sets the per-stream initial window size of HTTP/3 frontend connection. Default: ``256K`` .. option:: --frontend-http3-connection-window-size= Sets the per-connection window size of HTTP/3 frontend connection. Default: ``1M`` .. option:: --frontend-http3-max-window-size= Sets the maximum per-stream window size of HTTP/3 frontend connection. The window size is adjusted based on the receiving rate of stream data. The initial value is the value specified by :option:`--frontend-http3-window-size` and the window size grows up to bytes. Default: ``6M`` .. option:: --frontend-http3-max-connection-window-size= Sets the maximum per-connection window size of HTTP/3 frontend connection. The window size is adjusted based on the receiving rate of stream data. The initial value is the value specified by :option:`--frontend-http3-connection-window-size` and the window size grows up to bytes. Default: ``8M`` .. option:: --frontend-http3-max-concurrent-streams= Set the maximum number of the concurrent streams in one frontend HTTP/3 connection. Default: ``100`` Misc ~~~~ .. option:: --conf= Load configuration from . Please note that nghttpx always tries to read the default configuration file if :option:`--conf` is not given. Default: ``/etc/nghttpx/nghttpx.conf`` .. option:: --include= Load additional configurations from . File is read when configuration parser encountered this option. This option can be used multiple times, or even recursively. .. option:: -v, --version Print version and exit. .. option:: -h, --help Print this help and exit. The argument is an integer and an optional unit (e.g., 10K is 10 * 1024). Units are K, M and G (powers of 1024). The argument is an integer and an optional unit (e.g., 1s is 1 second and 500ms is 500 milliseconds). Units are h, m, s or ms (hours, minutes, seconds and milliseconds, respectively). If a unit is omitted, a second is used as unit. FILES ----- */etc/nghttpx/nghttpx.conf* The default configuration file path nghttpx searches at startup. The configuration file path can be changed using :option:`--conf` option. Those lines which are staring ``#`` are treated as comment. The option name in the configuration file is the long command-line option name with leading ``--`` stripped (e.g., ``frontend``). Put ``=`` between option name and value. Don't put extra leading or trailing spaces. When specifying arguments including characters which have special meaning to a shell, we usually use quotes so that shell does not interpret them. When writing this configuration file, quotes for this purpose must not be used. For example, specify additional request header field, do this: .. code-block:: text add-request-header=foo: bar instead of: .. code-block:: text add-request-header="foo: bar" The options which do not take argument in the command-line *take* argument in the configuration file. Specify ``yes`` as an argument (e.g., ``http2-proxy=yes``). If other string is given, it is ignored. To specify private key and certificate file which are given as positional arguments in command-line, use ``private-key-file`` and ``certificate-file``. :option:`--conf` option cannot be used in the configuration file and will be ignored if specified. Error log Error log is written to stderr by default. It can be configured using :option:`--errorlog-file`. The format of log message is as follows: (:) It is a combination of date and time when the log is written. It is in ISO 8601 format. It is a main process ID. It is a process ID which writes this log. It is a thread ID which writes this log. It would be unique within . and They are source file name, and line number which produce this log. It is a log message body. SIGNALS ------- SIGQUIT Shutdown gracefully. First accept pending connections and stop accepting connection. After all connections are handled, nghttpx exits. SIGHUP Reload configuration file given in :option:`--conf`. SIGUSR1 Reopen log files. SIGUSR2 Fork and execute nghttpx. It will execute the binary in the same path with same command-line arguments and environment variables. As of nghttpx version 1.20.0, the new main process sends SIGQUIT to the original main process when it is ready to serve requests. For the earlier versions of nghttpx, user has to send SIGQUIT to the original main process. The difference between SIGUSR2 (+ SIGQUIT) and SIGHUP is that former is usually used to execute new binary, and the main process is newly spawned. On the other hand, the latter just reloads configuration file, and the same main process continues to exist. .. note:: nghttpx consists of multiple processes: one process for processing these signals, and another one for processing requests. The former spawns the latter. The former is called main process, and the latter is called worker process. If neverbleed is enabled, the worker process spawns neverbleed daemon process which does RSA key processing. The above signal must be sent to the main process. If the other processes received one of them, it is ignored. This behaviour of these processes may change in the future release. In other words, in the future release, the processes other than main process may terminate upon the reception of these signals. Therefore these signals should not be sent to the processes other than main process. SERVER PUSH ----------- nghttpx supports HTTP/2 server push in default mode with Link header field. nghttpx looks for Link header field (`RFC 5988 `_) in response headers from backend server and extracts URI-reference with parameter ``rel=preload`` (see `preload `_) and pushes those URIs to the frontend client. Here is a sample Link header field to initiate server push: .. code-block:: text Link: ; rel=preload Link: ; rel=preload Currently, the following restriction is applied for server push: 1. The associated stream must have method "GET" or "POST". The associated stream's status code must be 200. This limitation may be loosened in the future release. nghttpx also supports server push if both frontend and backend are HTTP/2 in default mode. In this case, in addition to server push via Link header field, server push from backend is forwarded to frontend HTTP/2 session. HTTP/2 server push will be disabled if :option:`--http2-proxy` is used. UNIX DOMAIN SOCKET ------------------ nghttpx supports UNIX domain socket with a filename for both frontend and backend connections. Please note that current nghttpx implementation does not delete a socket with a filename. And on start up, if nghttpx detects that the specified socket already exists in the file system, nghttpx first deletes it. However, if SIGUSR2 is used to execute new binary and both old and new configurations use same filename, new binary does not delete the socket and continues to use it. TLS SESSION RESUMPTION ---------------------- nghttpx supports TLS session resumption through both session ID and session ticket. SESSION ID RESUMPTION ~~~~~~~~~~~~~~~~~~~~~ By default, session ID is shared by all worker threads. TLS SESSION TICKET RESUMPTION ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ By default, session ticket is shared by all worker threads. The automatic key rotation is also enabled by default. Every an hour, new encryption key is generated, and previous encryption key becomes decryption only key. We set session timeout to 12 hours, and thus we keep at most 12 keys. If :option:`--tls-ticket-key-memcached` is given, encryption keys are retrieved from memcached. nghttpx just reads keys from memcached; one has to deploy key generator program to update keys frequently (e.g., every 1 hour). The example key generator tlsticketupdate.go is available under contrib directory in nghttp2 archive. The memcached entry key is ``nghttpx:tls-ticket-key``. The data format stored in memcached is the binary format described below: .. code-block:: text +--------------+-------+----------------+ | VERSION (4) |LEN (2)|KEY(48 or 80) ... +--------------+-------+----------------+ ^ | | | +------------------------+ (LEN, KEY) pair can be repeated All numbers in the above figure is bytes. All integer fields are network byte order. First 4 bytes integer VERSION field, which must be 1. The 2 bytes integer LEN field gives the length of following KEY field, which contains key. If :option:`--tls-ticket-key-cipher`\=aes-128-cbc is used, LEN must be 48. If :option:`--tls-ticket-key-cipher`\=aes-256-cbc is used, LEN must be 80. LEN and KEY pair can be repeated multiple times to store multiple keys. The key appeared first is used as encryption key. All the remaining keys are used as decryption only. By default, connections to memcached server are not encrypted. To enable encryption, use ``tls`` keyword in :option:`--tls-ticket-key-memcached` option. If :option:`--tls-ticket-key-file` is given, encryption key is read from the given file. In this case, nghttpx does not rotate key automatically. To rotate key, one has to restart nghttpx (see SIGNALS). CERTIFICATE TRANSPARENCY ------------------------ nghttpx supports TLS ``signed_certificate_timestamp`` extension (`RFC 6962 `_). The relevant options are :option:`--tls-sct-dir` and ``sct-dir`` parameter in :option:`--subcert`. They takes a directory, and nghttpx reads all files whose extension is ``.sct`` under the directory. The ``*.sct`` files are encoded as ``SignedCertificateTimestamp`` struct described in `section 3.2 of RFC 69662 `_. This format is the same one used by `nginx-ct `_ and `mod_ssl_ct `_. `ct-submit `_ can be used to submit certificates to log servers, and obtain the ``SignedCertificateTimestamp`` struct which can be used with nghttpx. MRUBY SCRIPTING --------------- .. warning:: The current mruby extension API is experimental and not frozen. The API is subject to change in the future release. .. warning:: Almost all string value returned from method, or attribute is a fresh new mruby string, which involves memory allocation, and copies. Therefore, it is strongly recommended to store a return value in a local variable, and use it, instead of calling method or accessing attribute repeatedly. nghttpx allows users to extend its capability using mruby scripts. nghttpx has 2 hook points to execute mruby script: request phase and response phase. The request phase hook is invoked after all request header fields are received from client. The response phase hook is invoked after all response header fields are received from backend server. These hooks allows users to modify header fields, or common HTTP variables, like authority or request path, and even return custom response without forwarding request to backend servers. There are 2 levels of mruby script invocations: global and per-pattern. The global mruby script is set by :option:`--mruby-file` option and is called for all requests. The per-pattern mruby script is set by "mruby" parameter in :option:`-b` option. It is invoked for a request which matches the particular pattern. The order of hook invocation is: global request phase hook, per-pattern request phase hook, per-pattern response phase hook, and finally global response phase hook. If a hook returns a response, any later hooks are not invoked. The global request hook is invoked before the pattern matching is made and changing request path may affect the pattern matching. Please note that request and response hooks of per-pattern mruby script for a single request might not come from the same script. This might happen after a request hook is executed, backend failed for some reason, and at the same time, backend configuration is replaced by API request, and then the request uses new configuration on retry. The response hook from new configuration, if it is specified, will be invoked. The all mruby script will be evaluated once per thread on startup, and it must instantiate object and evaluate it as the return value (e.g., ``App.new``). This object is called app object. If app object defines ``on_req`` method, it is called with :rb:class:`Nghttpx::Env` object on request hook. Similarly, if app object defines ``on_resp`` method, it is called with :rb:class:`Nghttpx::Env` object on response hook. For each method invocation, user can can access :rb:class:`Nghttpx::Request` and :rb:class:`Nghttpx::Response` objects via :rb:attr:`Nghttpx::Env#req` and :rb:attr:`Nghttpx::Env#resp` respectively. .. rb:module:: Nghttpx .. rb:const:: REQUEST_PHASE Constant to represent request phase. .. rb:const:: RESPONSE_PHASE Constant to represent response phase. .. rb:class:: Env Object to represent current request specific context. .. rb:attr_reader:: req Return :rb:class:`Request` object. .. rb:attr_reader:: resp Return :rb:class:`Response` object. .. rb:attr_reader:: ctx Return Ruby hash object. It persists until request finishes. So values set in request phase hook can be retrieved in response phase hook. .. rb:attr_reader:: phase Return the current phase. .. rb:attr_reader:: remote_addr Return IP address of a remote client. If connection is made via UNIX domain socket, this returns the string "localhost". .. rb:attr_reader:: server_addr Return address of server that accepted the connection. This is a string which specified in :option:`--frontend` option, excluding port number, and not a resolved IP address. For UNIX domain socket, this is a path to UNIX domain socket. .. rb:attr_reader:: server_port Return port number of the server frontend which accepted the connection from client. .. rb:attr_reader:: tls_used Return true if TLS is used on the connection. .. rb:attr_reader:: tls_sni Return the TLS SNI value which client sent in this connection. .. rb:attr_reader:: tls_client_fingerprint_sha256 Return the SHA-256 fingerprint of a client certificate. .. rb:attr_reader:: tls_client_fingerprint_sha1 Return the SHA-1 fingerprint of a client certificate. .. rb:attr_reader:: tls_client_issuer_name Return the issuer name of a client certificate. .. rb:attr_reader:: tls_client_subject_name Return the subject name of a client certificate. .. rb:attr_reader:: tls_client_serial Return the serial number of a client certificate. .. rb:attr_reader:: tls_client_not_before Return the start date of a client certificate in seconds since the epoch. .. rb:attr_reader:: tls_client_not_after Return the end date of a client certificate in seconds since the epoch. .. rb:attr_reader:: tls_cipher Return a TLS cipher negotiated in this connection. .. rb:attr_reader:: tls_protocol Return a TLS protocol version negotiated in this connection. .. rb:attr_reader:: tls_session_id Return a session ID for this connection in hex string. .. rb:attr_reader:: tls_session_reused Return true if, and only if a SSL/TLS session is reused. .. rb:attr_reader:: alpn Return ALPN identifier negotiated in this connection. .. rb:attr_reader:: tls_handshake_finished Return true if SSL/TLS handshake has finished. If it returns false in the request phase hook, the request is received in TLSv1.3 early data (0-RTT) and might be vulnerable to the replay attack. nghttpx will send Early-Data header field to backend servers to indicate this. .. rb:class:: Request Object to represent request from client. The modification to Request object is allowed only in request phase hook. .. rb:attr_reader:: http_version_major Return HTTP major version. .. rb:attr_reader:: http_version_minor Return HTTP minor version. .. rb:attr_accessor:: method HTTP method. On assignment, copy of given value is assigned. We don't accept arbitrary method name. We will document them later, but well known methods, like GET, PUT and POST, are all supported. .. rb:attr_accessor:: authority Authority (i.e., example.org), including optional port component . On assignment, copy of given value is assigned. .. rb:attr_accessor:: scheme Scheme (i.e., http, https). On assignment, copy of given value is assigned. .. rb:attr_accessor:: path Request path, including query component (i.e., /index.html). On assignment, copy of given value is assigned. The path does not include authority component of URI. This may include query component. nghttpx makes certain normalization for path. It decodes percent-encoding for unreserved characters (see https://tools.ietf.org/html/rfc3986#section-2.3), and resolves ".." and ".". But it may leave characters which should be percent-encoded as is. So be careful when comparing path against desired string. .. rb:attr_reader:: headers Return Ruby hash containing copy of request header fields. Changing values in returned hash does not change request header fields actually used in request processing. Use :rb:meth:`Nghttpx::Request#add_header` or :rb:meth:`Nghttpx::Request#set_header` to change request header fields. .. rb:method:: add_header(key, value) Add header entry associated with key. The value can be single string or array of string. It does not replace any existing values associated with key. .. rb:method:: set_header(key, value) Set header entry associated with key. The value can be single string or array of string. It replaces any existing values associated with key. .. rb:method:: clear_headers Clear all existing request header fields. .. rb:method:: push(uri) Initiate to push resource identified by *uri*. Only HTTP/2 protocol supports this feature. For the other protocols, this method is noop. *uri* can be absolute URI, absolute path or relative path to the current request. For absolute or relative path, scheme and authority are inherited from the current request. Currently, method is always GET. nghttpx will issue request to backend servers to fulfill this request. The request and response phase hooks will be called for pushed resource as well. .. rb:class:: Response Object to represent response from backend server. .. rb:attr_reader:: http_version_major Return HTTP major version. .. rb:attr_reader:: http_version_minor Return HTTP minor version. .. rb:attr_accessor:: status HTTP status code. It must be in the range [200, 999], inclusive. The non-final status code is not supported in mruby scripting at the moment. .. rb:attr_reader:: headers Return Ruby hash containing copy of response header fields. Changing values in returned hash does not change response header fields actually used in response processing. Use :rb:meth:`Nghttpx::Response#add_header` or :rb:meth:`Nghttpx::Response#set_header` to change response header fields. .. rb:method:: add_header(key, value) Add header entry associated with key. The value can be single string or array of string. It does not replace any existing values associated with key. .. rb:method:: set_header(key, value) Set header entry associated with key. The value can be single string or array of string. It replaces any existing values associated with key. .. rb:method:: clear_headers Clear all existing response header fields. .. rb:method:: return(body) Return custom response *body* to a client. When this method is called in request phase hook, the request is not forwarded to the backend, and response phase hook for this request will not be invoked. When this method is called in response phase hook, response from backend server is canceled and discarded. The status code and response header fields should be set before using this method. To set status code, use :rb:attr:`Nghttpx::Response#status`. If status code is not set, 200 is used. To set response header fields, :rb:meth:`Nghttpx::Response#add_header` and :rb:meth:`Nghttpx::Response#set_header`. When this method is invoked in response phase hook, the response headers are filled with the ones received from backend server. To send completely custom header fields, first call :rb:meth:`Nghttpx::Response#clear_headers` to erase all existing header fields, and then add required header fields. It is an error to call this method twice for a given request. .. rb:method:: send_info(status, headers) Send non-final (informational) response to a client. *status* must be in the range [100, 199], inclusive. *headers* is a hash containing response header fields. Its key must be a string, and the associated value must be either string or array of strings. Since this is not a final response, even if this method is invoked, request is still forwarded to a backend unless :rb:meth:`Nghttpx::Response#return` is called. This method can be called multiple times. It cannot be called after :rb:meth:`Nghttpx::Response#return` is called. MRUBY EXAMPLES ~~~~~~~~~~~~~~ Modify request path: .. code-block:: ruby class App def on_req(env) env.req.path = "/apps#{env.req.path}" end end App.new Don't forget to instantiate and evaluate object at the last line. Restrict permission of viewing a content to a specific client addresses: .. code-block:: ruby class App def on_req(env) allowed_clients = ["127.0.0.1", "::1"] if env.req.path.start_with?("/log/") && !allowed_clients.include?(env.remote_addr) then env.resp.status = 404 env.resp.return "permission denied" end end end App.new API ENDPOINTS ------------- nghttpx exposes API endpoints to manipulate it via HTTP based API. By default, API endpoint is disabled. To enable it, add a dedicated frontend for API using :option:`--frontend` option with "api" parameter. All requests which come from this frontend address, will be treated as API request. The response is normally JSON dictionary, and at least includes the following keys: status The status of the request processing. The following values are defined: Success The request was successful. Failure The request was failed. No change has been made. code HTTP status code Additionally, depending on the API endpoint, ``data`` key may be present, and its value contains the API endpoint specific data. We wrote "normally", since nghttpx may return ordinal HTML response in some cases where the error has occurred before reaching API endpoint (e.g., header field is too large). The following section describes available API endpoints. POST /api/v1beta1/backendconfig ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This API replaces the current backend server settings with the requested ones. The request method should be POST, but PUT is also acceptable. The request body must be nghttpx configuration file format. For configuration file format, see `FILES`_ section. The line separator inside the request body must be single LF (0x0A). Currently, only :option:`backend <--backend>` option is parsed, the others are simply ignored. The semantics of this API is replace the current backend with the backend options in request body. Describe the desired set of backend severs, and nghttpx makes it happen. If there is no :option:`backend <--backend>` option is found in request body, the current set of backend is replaced with the :option:`backend <--backend>` option's default value, which is ``127.0.0.1,80``. The replacement is done instantly without breaking existing connections or requests. It also avoids any process creation as is the case with hot swapping with signals. The one limitation is that only numeric IP address is allowed in :option:`backend <--backend>` in request body unless "dns" parameter is used while non numeric hostname is allowed in command-line or configuration file is read using :option:`--conf`. GET /api/v1beta1/configrevision ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This API returns configuration revision of the current nghttpx. The configuration revision is opaque string, and it changes after each reloading by SIGHUP. With this API, an external application knows that whether nghttpx has finished reloading its configuration by comparing the configuration revisions between before and after reloading.

[ ] .SH DESCRIPTION .sp A reverse proxy for HTTP/3, HTTP/2, and HTTP/1. .INDENT 0.0 .TP .B Set path to server\(aqs private key. Required unless \(dqno\-tls\(dq parameter is used in \fB\-\-frontend\fP option. .UNINDENT .INDENT 0.0 .TP .B Set path to server\(aqs certificate. Required unless \(dqno\-tls\(dq parameter is used in \fB\-\-frontend\fP option. .UNINDENT .SH OPTIONS .sp The options are categorized into several groups. .SS Connections .INDENT 0.0 .TP .B \-b, \-\-backend=(,|unix:)[;[[:...]][[;]...] Set backend host and port. The multiple backend addresses are accepted by repeating this option. UNIX domain socket can be specified by prefixing path name with \(dqunix:\(dq (e.g., unix:/var/run/backend.sock). .sp Optionally, if s are given, the backend address is only used if request matches the pattern. The pattern matching is closely designed to ServeMux in net/http package of Go programming language. consists of path, host + path or just host. The path must start with \(dq\fI/\fP\(dq. If it ends with \(dq\fI/\fP\(dq, it matches all request path in its subtree. To deal with the request to the directory without trailing slash, the path which ends with \(dq\fI/\fP\(dq also matches the request path which only lacks trailing \(aq\fI/\fP\(aq (e.g., path \(dq\fI/foo/\fP\(dq matches request path \(dq\fI/foo\fP\(dq). If it does not end with \(dq\fI/\fP\(dq, it performs exact match against the request path. If host is given, it performs a match against the request host. For a request received on the frontend listener with \(dqsni\-fwd\(dq parameter enabled, SNI host is used instead of a request host. If host alone is given, \(dq\fI/\fP\(dq is appended to it, so that it matches all request paths under the host (e.g., specifying \(dqnghttp2.org\(dq equals to \(dqnghttp2.org/\(dq). CONNECT method is treated specially. It does not have path, and we don\(aqt allow empty path. To workaround this, we assume that CONNECT method has \(dq\fI/\fP\(dq as path. .sp Patterns with host take precedence over patterns with just path. Then, longer patterns take precedence over shorter ones. .sp Host can include \(dq*\(dq in the left most position to indicate wildcard match (only suffix match is done). The \(dq*\(dq must match at least one character. For example, host pattern \(dq*.nghttp2.org\(dq matches against \(dqwww.nghttp2.org\(dq and \(dqgit.ngttp2.org\(dq, but does not match against \(dqnghttp2.org\(dq. The exact hosts match takes precedence over the wildcard hosts match. .sp If path part ends with \(dq*\(dq, it is treated as wildcard path. The wildcard path behaves differently from the normal path. For normal path, match is made around the boundary of path component separator,\(dq\fI/\fP\(dq. On the other hand, the wildcard path does not take into account the path component separator. All paths which include the wildcard path without last \(dq*\(dq as prefix, and are strictly longer than wildcard path without last \(dq*\(dq are matched. \(dq*\(dq must match at least one character. For example, the pattern \(dq\fI/foo*\fP\(dq matches \(dq\fI/foo/\fP\(dq and \(dq\fI/foobar\fP\(dq. But it does not match \(dq\fI/foo\fP\(dq, or \(dq\fI/fo\fP\(dq. .sp If is omitted or empty string, \(dq\fI/\fP\(dq is used as pattern, which matches all request paths (catch\-all pattern). The catch\-all backend must be given. .sp When doing a match, nghttpx made some normalization to pattern, request host and path. For host part, they are converted to lower case. For path part, percent\-encoded unreserved characters defined in RFC 3986 are decoded, and any dot\-segments (\(dq..\(dq and \(dq.\(dq) are resolved and removed. .sp For example, \fB\-b\fP\(aq127.0.0.1,8080;nghttp2.org/httpbin/\(aq matches the request host \(dqnghttp2.org\(dq and the request path \(dq\fI/httpbin/get\fP\(dq, but does not match the request host \(dqnghttp2.org\(dq and the request path \(dq\fI/index.html\fP\(dq. .sp The multiple s can be specified, delimiting them by \(dq:\(dq. Specifying \fB\-b\fP\(aq127.0.0.1,8080;nghttp2.org:www.nghttp2.org\(aq has the same effect to specify \fB\-b\fP\(aq127.0.0.1,8080;nghttp2.org\(aq and \fB\-b\fP\(aq127.0.0.1,8080;www.nghttp2.org\(aq. .sp The backend addresses sharing same are grouped together forming load balancing group. .sp Several parameters are accepted after . The parameters are delimited by \(dq;\(dq. The available parameters are: \(dqproto=\(dq, \(dqtls\(dq, \(dqsni=\(dq, \(dqfall=\(dq, \(dqrise=\(dq, \(dqaffinity=\(dq, \(dqdns\(dq, \(dqredirect\-if\-not\-tls\(dq, \(dqupgrade\-scheme\(dq, \(dqmruby=\(dq, \(dqread\-timeout=\(dq, \(dqwrite\-timeout=\(dq, \(dqgroup=\(dq, \(dqgroup\-weight=\(dq, \(dqweight=\(dq, and \(dqdnf\(dq. The parameter consists of keyword, and optionally followed by \(dq=\(dq and value. For example, the parameter \(dqproto=h2\(dq consists of the keyword \(dqproto\(dq and value \(dqh2\(dq. The parameter \(dqtls\(dq consists of the keyword \(dqtls\(dq without value. Each parameter is described as follows. .sp The backend application protocol can be specified using optional \(dqproto\(dq parameter, and in the form of \(dqproto=\(dq. should be one of the following list without quotes: \(dqh2\(dq, \(dqhttp/1.1\(dq. The default value of is \(dqhttp/1.1\(dq. Note that usually \(dqh2\(dq refers to HTTP/2 over TLS. But in this option, it may mean HTTP/2 over cleartext TCP unless \(dqtls\(dq keyword is used (see below). .sp TLS can be enabled by specifying optional \(dqtls\(dq parameter. TLS is not enabled by default. .sp With \(dqsni=\(dq parameter, it can override the TLS SNI field value with given . This will default to the backend name .sp The feature to detect whether backend is online or offline can be enabled using optional \(dqfall\(dq and \(dqrise\(dq parameters. Using \(dqfall=\(dq parameter, if nghttpx cannot connect to a this backend times in a row, this backend is assumed to be offline, and it is excluded from load balancing. If is 0, this backend never be excluded from load balancing whatever times nghttpx cannot connect to it, and this is the default. There is also \(dqrise=\(dq parameter. After backend was excluded from load balancing group, nghttpx periodically attempts to make a connection to the failed backend, and if the connection is made successfully times in a row, the backend is assumed to be online, and it is now eligible for load balancing target. If is 0, a backend is permanently offline, once it goes in that state, and this is the default behaviour. .sp The session affinity is enabled using \(dqaffinity=\(dq parameter. If \(dqip\(dq is given in , client IP based session affinity is enabled. If \(dqcookie\(dq is given in , cookie based session affinity is enabled. If \(dqnone\(dq is given in , session affinity is disabled, and this is the default. The session affinity is enabled per . If at least one backend has \(dqaffinity\(dq parameter, and its is not \(dqnone\(dq, session affinity is enabled for all backend servers sharing the same . It is advised to set \(dqaffinity\(dq parameter to all backend explicitly if session affinity is desired. The session affinity may break if one of the backend gets unreachable, or backend settings are reloaded or replaced by API. .sp If \(dqaffinity=cookie\(dq is used, the additional configuration is required. \(dqaffinity\-cookie\-name=\(dq must be used to specify a name of cookie to use. Optionally, \(dqaffinity\-cookie\-path=\(dq can be used to specify a path which cookie is applied. The optional \(dqaffinity\-cookie\-secure=\(dq controls the Secure attribute of a cookie. The default value is \(dqauto\(dq, and the Secure attribute is determined by a request scheme. If a request scheme is \(dqhttps\(dq, then Secure attribute is set. Otherwise, it is not set. If is \(dqyes\(dq, the Secure attribute is always set. If is \(dqno\(dq, the Secure attribute is always omitted. \(dqaffinity\-cookie\-stickiness=\(dq controls stickiness of this affinity. If is \(dqloose\(dq, removing or adding a backend server might break the affinity and the request might be forwarded to a different backend server. If is \(dqstrict\(dq, removing the designated backend server breaks affinity, but adding new backend server does not cause breakage. If the designated backend server becomes unavailable, new backend server is chosen as if the request does not have an affinity cookie. defaults to \(dqloose\(dq. .sp By default, name resolution of backend host name is done at start up, or reloading configuration. If \(dqdns\(dq parameter is given, name resolution takes place dynamically. This is useful if backend address changes frequently. If \(dqdns\(dq is given, name resolution of backend host name at start up, or reloading configuration is skipped. .sp If \(dqredirect\-if\-not\-tls\(dq parameter is used, the matched backend requires that frontend connection is TLS encrypted. If it isn\(aqt, nghttpx responds to the request with 308 status code, and https URI the client should use instead is included in Location header field. The port number in redirect URI is 443 by default, and can be changed using \fB\-\-redirect\-https\-port\fP option. If at least one backend has \(dqredirect\-if\-not\-tls\(dq parameter, this feature is enabled for all backend servers sharing the same . It is advised to set \(dqredirect\-if\-no\-tls\(dq parameter to all backends explicitly if this feature is desired. .sp If \(dqupgrade\-scheme\(dq parameter is used along with \(dqtls\(dq parameter, HTTP/2 :scheme pseudo header field is changed to \(dqhttps\(dq from \(dqhttp\(dq when forwarding a request to this particular backend. This is a workaround for a backend server which requires \(dqhttps\(dq :scheme pseudo header field on TLS encrypted connection. .sp \(dqmruby=\(dq parameter specifies a path to mruby script file which is invoked when this pattern is matched. All backends which share the same pattern must have the same mruby path. .sp \(dqread\-timeout=\(dq and \(dqwrite\-timeout=\(dq parameters specify the read and write timeout of the backend connection when this pattern is matched. All backends which share the same pattern must have the same timeouts. If these timeouts are entirely omitted for a pattern, \fB\-\-backend\-read\-timeout\fP and \fB\-\-backend\-write\-timeout\fP are used. .sp \(dqgroup=\(dq parameter specifies the name of group this backend address belongs to. By default, it belongs to the unnamed default group. The name of group is unique per pattern. \(dqgroup\-weight=\(dq parameter specifies the weight of the group. The higher weight gets more frequently selected by the load balancing algorithm. must be [1, 256] inclusive. The weight 8 has 4 times more weight than 2. must be the same for all addresses which share the same . If \(dqgroup\-weight\(dq is omitted in an address, but the other address which belongs to the same group specifies \(dqgroup\-weight\(dq, its weight is used. If no \(dqgroup\-weight\(dq is specified for all addresses, the weight of a group becomes 1. \(dqgroup\(dq and \(dqgroup\-weight\(dq are ignored if session affinity is enabled. .sp \(dqweight=\(dq parameter specifies the weight of the backend address inside a group which this address belongs to. The higher weight gets more frequently selected by the load balancing algorithm. must be [1, 256] inclusive. The weight 8 has 4 times more weight than weight 2. If this parameter is omitted, weight becomes 1. \(dqweight\(dq is ignored if session affinity is enabled. .sp If \(dqdnf\(dq parameter is specified, an incoming request is not forwarded to a backend and just consumed along with the request body (actually a backend server never be contacted). It is expected that the HTTP response is generated by mruby script (see \(dqmruby=\(dq parameter above). \(dqdnf\(dq is an abbreviation of \(dqdo not forward\(dq. .sp Since \(dq;\(dq and \(dq:\(dq are used as delimiter, must not contain these characters. In order to include \(dq:\(dq in , one has to specify \(dq%3A\(dq (which is percent\-encoded from of \(dq:\(dq) instead. Since \(dq;\(dq has special meaning in shell, the option value must be quoted. .sp Default: \fB127.0.0.1,80\fP .UNINDENT .INDENT 0.0 .TP .B \-f, \-\-frontend=(,|unix:)[[;]...] Set frontend host and port. If is \(aq*\(aq, it assumes all addresses including both IPv4 and IPv6. UNIX domain socket can be specified by prefixing path name with \(dqunix:\(dq (e.g., unix:/var/run/nghttpx.sock). This option can be used multiple times to listen to multiple addresses. .sp This option can take 0 or more parameters, which are described below. Note that \(dqapi\(dq and \(dqhealthmon\(dq parameters are mutually exclusive. .sp Optionally, TLS can be disabled by specifying \(dqno\-tls\(dq parameter. TLS is enabled by default. .sp If \(dqsni\-fwd\(dq parameter is used, when performing a match to select a backend server, SNI host name received from the client is used instead of the request host. See \fB\-\-backend\fP option about the pattern match. .sp To make this frontend as API endpoint, specify \(dqapi\(dq parameter. This is disabled by default. It is important to limit the access to the API frontend. Otherwise, someone may change the backend server, and break your services, or expose confidential information to the outside the world. .sp To make this frontend as health monitor endpoint, specify \(dqhealthmon\(dq parameter. This is disabled by default. Any requests which come through this address are replied with 200 HTTP status, without no body. .sp To accept PROXY protocol version 1 and 2 on frontend connection, specify \(dqproxyproto\(dq parameter. This is disabled by default. .sp To receive HTTP/3 (QUIC) traffic, specify \(dqquic\(dq parameter. It makes nghttpx listen on UDP port rather than TCP port. UNIX domain socket, \(dqapi\(dq, and \(dqhealthmon\(dq parameters cannot be used with \(dqquic\(dq parameter. .sp Default: \fB*,3000\fP .UNINDENT .INDENT 0.0 .TP .B \-\-backlog= Set listen backlog size. .sp Default: \fB65536\fP .UNINDENT .INDENT 0.0 .TP .B \-\-backend\-address\-family=(auto|IPv4|IPv6) Specify address family of backend connections. If \(dqauto\(dq is given, both IPv4 and IPv6 are considered. If \(dqIPv4\(dq is given, only IPv4 address is considered. If \(dqIPv6\(dq is given, only IPv6 address is considered. .sp Default: \fBauto\fP .UNINDENT .INDENT 0.0 .TP .B \-\-backend\-http\-proxy\-uri= Specify proxy URI in the form \%/[:@]:. If a proxy requires authentication, specify and . Note that they must be properly percent\-encoded. This proxy is used when the backend connection is HTTP/2. First, make a CONNECT request to the proxy and it connects to the backend on behalf of nghttpx. This forms tunnel. After that, nghttpx performs SSL/TLS handshake with the downstream through the tunnel. The timeouts when connecting and making CONNECT request can be specified by \fB\-\-backend\-read\-timeout\fP and \fB\-\-backend\-write\-timeout\fP options. .UNINDENT .SS Performance .INDENT 0.0 .TP .B \-n, \-\-workers= Set the number of worker threads. .sp Default: \fB1\fP .UNINDENT .INDENT 0.0 .TP .B \-\-single\-thread Run everything in one thread inside the worker process.

If threading is disabled, this option is always enabled. .UNINDENT .INDENT 0.0 .TP .B \-\-read\-rate= Set maximum average read rate on frontend connection. Setting 0 to this option means read rate is unlimited. .sp Default: \fB0\fP .UNINDENT .INDENT 0.0 .TP .B \-\-read\-burst= Set maximum read burst size on frontend connection. Setting 0 to this option means read burst size is unlimited. .sp Default: \fB0\fP .UNINDENT .INDENT 0.0 .TP .B \-\-write\-rate= Set maximum average write rate on frontend connection.

Setting 0 means unlimited. .sp Default: \fB0\fP .UNINDENT .INDENT 0.0 .TP .B \-\-backend\-connections\-per\-host= Set maximum number of backend concurrent connections (and/or streams in case of HTTP/2) per origin host. This option is meaningful when \fB\-\-http2\-proxy\fP option is used. The origin host is determined by authority portion of request URI (or :authority header field for HTTP/2). To limit the number of connections per frontend for default mode, use \fB\-\-backend\-connections\-per\-frontend\fP\&. .sp Default: \fB8\fP .UNINDENT .INDENT 0.0 .TP .B \-\-backend\-connections\-per\-frontend= Set maximum number of backend concurrent connections (and/or streams in case of HTTP/2) per frontend. This option is only used for default mode. 0 means unlimited.

Without this option, nghttpx creates at least 2 processes: main and worker processes. If this option is used, main and worker are unified into a single process. nghttpx still spawns additional process if neverbleed is used. In the single process mode, the signal handling feature is disabled. .UNINDENT .INDENT 0.0 .TP .B \-\-max\-worker\-processes= The maximum number of worker processes. nghttpx spawns new worker process when it reloads its configuration. The previous worker process enters graceful termination period and will terminate when it finishes handling the existing connections. However, if reloading configurations happen very frequently, the worker processes might be piled up if they take a bit long time to finish the existing connections. With this option, if the number of worker processes exceeds the given value, the oldest worker process is terminated immediately. Specifying 0 means no limit and it is the default behaviour. .UNINDENT .INDENT 0.0 .TP .B \-\-worker\-process\-grace\-shutdown\-period= Maximum period for a worker process to terminate gracefully. When a worker process enters in graceful shutdown period (e.g., when nghttpx reloads its configuration) and it does not finish handling the existing connections in the given period of time, it is immediately terminated. Specifying 0 means no limit and it is the default behaviour. .UNINDENT .SS Scripting .INDENT 0.0 .TP .B \-\-mruby\-file= Set mruby script file .UNINDENT .INDENT 0.0 .TP .B \-\-ignore\-per\-pattern\-mruby\-error Ignore mruby compile error for per\-pattern mruby script file.

It is used to derive keys for encrypting tokens and Connection IDs. It is not used to encrypt QUIC packets. Each line of this file must contain exactly 136 bytes hex\-encoded string (when decoded the byte string is 68 bytes long). The first 3 bits of decoded byte string are used to identify the keying material. An empty line or a line which starts \(aq#\(aq is ignored. The file can contain more than one keying materials. Because the identifier is 3 bits, at most 8 keying materials are read and the remaining data is discarded. The first keying material in the file is primarily used for encryption and decryption for new connection. The other ones are used to decrypt data for the existing connections. Specifying multiple keying materials enables key rotation. Please note that key rotation does not occur automatically. User should update files or change options values and restart nghttpx gracefully. If opening or reading given file fails, all loaded keying materials are discarded and it is treated as if none of this option is given. If this option is not given or an error occurred while opening or reading a file, a keying material is generated internally on startup and reload. .UNINDENT .INDENT 0.0 .TP .B \-\-quic\-server\-id= Specify server ID encoded in Connection ID to identify this particular server instance. Connection ID is encrypted and this part is not visible in public. It must be 4 bytes long and must be encoded in hex string (which is 8 bytes long).

Units are K, M and G (powers of 1024). .sp The argument is an integer and an optional unit (e.g., 1s is 1 second and 500ms is 500 milliseconds). Units are h, m, s or ms (hours, minutes, seconds and milliseconds, respectively). If a unit is omitted, a second is used as unit. .SH FILES .INDENT 0.0 .TP .B \fI/etc/nghttpx/nghttpx.conf\fP The default configuration file path nghttpx searches at startup. The configuration file path can be changed using \fB\-\-conf\fP option. .sp Those lines which are staring \fB#\fP are treated as comment. .sp The option name in the configuration file is the long command\-line option name with leading \fB\-\-\fP stripped (e.g., \fBfrontend\fP). Put \fB=\fP between option name and value. Don\(aqt put extra leading or trailing spaces. .sp When specifying arguments including characters which have special meaning to a shell, we usually use quotes so that shell does not interpret them. When writing this configuration file, quotes for this purpose must not be used. For example, specify additional request header field, do this: .INDENT 7.0 .INDENT 3.5 .sp .EX add\-request\-header=foo: bar .EE .UNINDENT .UNINDENT .sp instead of: .INDENT 7.0 .INDENT 3.5 .sp .EX add\-request\-header=\(dqfoo: bar\(dq .EE .UNINDENT .UNINDENT .sp The options which do not take argument in the command\-line \fItake\fP argument in the configuration file. Specify \fByes\fP as an argument (e.g., \fBhttp2\-proxy=yes\fP). If other string is given, it is ignored. .sp To specify private key and certificate file which are given as positional arguments in command\-line, use \fBprivate\-key\-file\fP and \fBcertificate\-file\fP\&. .sp \fB\-\-conf\fP option cannot be used in the configuration file and will be ignored if specified. .TP .B Error log Error log is written to stderr by default. It can be configured using \fB\-\-errorlog\-file\fP\&. The format of log message is as follows: .sp (:) .INDENT 7.0 .TP .B It is a combination of date and time when the log is written.

It would be unique within . .TP .B and They are source file name, and line number which produce this log. .TP .B It is a log message body. .UNINDENT .UNINDENT .SH SIGNALS .INDENT 0.0 .TP .B SIGQUIT Shutdown gracefully. First accept pending connections and stop accepting connection. After all connections are handled, nghttpx exits. .TP .B SIGHUP Reload configuration file given in \fB\-\-conf\fP\&. .TP .B SIGUSR1 Reopen log files. .UNINDENT .sp SIGUSR2 .INDENT 0.0 .INDENT 3.5 Fork and execute nghttpx. It will execute the binary in the same path with same command\-line arguments and environment variables. As of nghttpx version 1.20.0, the new main process sends SIGQUIT to the original main process when it is ready to serve requests. For the earlier versions of nghttpx, user has to send SIGQUIT to the original main process. .sp The difference between SIGUSR2 (+ SIGQUIT) and SIGHUP is that former is usually used to execute new binary, and the main process is newly spawned. On the other hand, the latter just reloads configuration file, and the same main process continues to exist. .UNINDENT .UNINDENT .sp \fBNote:\fP .INDENT 0.0 .INDENT 3.5 nghttpx consists of multiple processes: one process for processing these signals, and another one for processing requests. The former spawns the latter. The former is called main process, and the latter is called worker process. If neverbleed is enabled, the worker process spawns neverbleed daemon process which does RSA key processing. The above signal must be sent to the main process. If the other processes received one of them, it is ignored. This behaviour of these processes may change in the future release. In other words, in the future release, the processes other than main process may terminate upon the reception of these signals. Therefore these signals should not be sent to the processes other than main process. .UNINDENT .UNINDENT .SH SERVER PUSH .sp nghttpx supports HTTP/2 server push in default mode with Link header field. nghttpx looks for Link header field (RFC 5988 \%) in response headers from backend server and extracts URI\-reference with parameter \fBrel=preload\fP (see preload \%) and pushes those URIs to the frontend client. Here is a sample Link header field to initiate server push: .INDENT 0.0 .INDENT 3.5 .sp .EX Link: ; rel=preload Link: ; rel=preload .EE .UNINDENT .UNINDENT .sp Currently, the following restriction is applied for server push: .INDENT 0.0 .IP 1. 3 The associated stream must have method \(dqGET\(dq or \(dqPOST\(dq. The associated stream\(aqs status code must be 200. .UNINDENT .sp This limitation may be loosened in the future release. .sp nghttpx also supports server push if both frontend and backend are HTTP/2 in default mode. In this case, in addition to server push via Link header field, server push from backend is forwarded to frontend HTTP/2 session. .sp HTTP/2 server push will be disabled if \fB\-\-http2\-proxy\fP is used. .SH UNIX DOMAIN SOCKET .sp nghttpx supports UNIX domain socket with a filename for both frontend and backend connections. .sp Please note that current nghttpx implementation does not delete a socket with a filename. And on start up, if nghttpx detects that the specified socket already exists in the file system, nghttpx first deletes it. However, if SIGUSR2 is used to execute new binary and both old and new configurations use same filename, new binary does not delete the socket and continues to use it. .SH TLS SESSION RESUMPTION .sp nghttpx supports TLS session resumption through both session ID and session ticket. .SS SESSION ID RESUMPTION .sp By default, session ID is shared by all worker threads. .SS TLS SESSION TICKET RESUMPTION .sp By default, session ticket is shared by all worker threads. The automatic key rotation is also enabled by default. Every an hour, new encryption key is generated, and previous encryption key becomes decryption only key. We set session timeout to 12 hours, and thus we keep at most 12 keys. .sp If \fB\-\-tls\-ticket\-key\-memcached\fP is given, encryption keys are retrieved from memcached. nghttpx just reads keys from memcached; one has to deploy key generator program to update keys frequently (e.g., every 1 hour). The example key generator tlsticketupdate.go is available under contrib directory in nghttp2 archive. The memcached entry key is \fBnghttpx:tls\-ticket\-key\fP\&. The data format stored in memcached is the binary format described below: .INDENT 0.0 .INDENT 3.5 .sp .EX +\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ | VERSION (4) |LEN (2)|KEY(48 or 80) ... +\-\-\-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ ^ | | | +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ (LEN, KEY) pair can be repeated .EE .UNINDENT .UNINDENT .sp All numbers in the above figure is bytes. All integer fields are network byte order. .sp First 4 bytes integer VERSION field, which must be 1. The 2 bytes integer LEN field gives the length of following KEY field, which contains key. If \fB\-\-tls\-ticket\-key\-cipher\fP=aes\-128\-cbc is used, LEN must be 48. If \fB\-\-tls\-ticket\-key\-cipher\fP=aes\-256\-cbc is used, LEN must be 80. LEN and KEY pair can be repeated multiple times to store multiple keys. The key appeared first is used as encryption key. All the remaining keys are used as decryption only. .sp By default, connections to memcached server are not encrypted. To enable encryption, use \fBtls\fP keyword in \fB\-\-tls\-ticket\-key\-memcached\fP option. .sp If \fB\-\-tls\-ticket\-key\-file\fP is given, encryption key is read from the given file. In this case, nghttpx does not rotate key automatically. To rotate key, one has to restart nghttpx (see SIGNALS). .SH CERTIFICATE TRANSPARENCY .sp nghttpx supports TLS \fBsigned_certificate_timestamp\fP extension (RFC 6962 \%). The relevant options are \fB\-\-tls\-sct\-dir\fP and \fBsct\-dir\fP parameter in \fB\-\-subcert\fP\&. They takes a directory, and nghttpx reads all files whose extension is \fB\&.sct\fP under the directory. The \fB*.sct\fP files are encoded as \fBSignedCertificateTimestamp\fP struct described in section 3.2 of RFC 69662 \%\&. This format is the same one used by nginx\-ct \% and mod_ssl_ct \%\&. ct\-submit \% can be used to submit certificates to log servers, and obtain the \fBSignedCertificateTimestamp\fP struct which can be used with nghttpx. .SH MRUBY SCRIPTING .sp \fBWarning:\fP .INDENT 0.0 .INDENT 3.5 The current mruby extension API is experimental and not frozen. The API is subject to change in the future release. .UNINDENT .UNINDENT .sp \fBWarning:\fP .INDENT 0.0 .INDENT 3.5 Almost all string value returned from method, or attribute is a fresh new mruby string, which involves memory allocation, and copies. Therefore, it is strongly recommended to store a return value in a local variable, and use it, instead of calling method or accessing attribute repeatedly. .UNINDENT .UNINDENT .sp nghttpx allows users to extend its capability using mruby scripts. nghttpx has 2 hook points to execute mruby script: request phase and response phase. The request phase hook is invoked after all request header fields are received from client. The response phase hook is invoked after all response header fields are received from backend server. These hooks allows users to modify header fields, or common HTTP variables, like authority or request path, and even return custom response without forwarding request to backend servers. .sp There are 2 levels of mruby script invocations: global and per\-pattern. The global mruby script is set by \fB\-\-mruby\-file\fP option and is called for all requests. The per\-pattern mruby script is set by \(dqmruby\(dq parameter in \fB\-b\fP option. It is invoked for a request which matches the particular pattern. The order of hook invocation is: global request phase hook, per\-pattern request phase hook, per\-pattern response phase hook, and finally global response phase hook. If a hook returns a response, any later hooks are not invoked. The global request hook is invoked before the pattern matching is made and changing request path may affect the pattern matching. .sp Please note that request and response hooks of per\-pattern mruby script for a single request might not come from the same script. This might happen after a request hook is executed, backend failed for some reason, and at the same time, backend configuration is replaced by API request, and then the request uses new configuration on retry. The response hook from new configuration, if it is specified, will be invoked. .sp The all mruby script will be evaluated once per thread on startup, and it must instantiate object and evaluate it as the return value (e.g., \fBApp.new\fP). This object is called app object. If app object defines \fBon_req\fP method, it is called with \fBNghttpx::Env\fP object on request hook. Similarly, if app object defines \fBon_resp\fP method, it is called with \fBNghttpx::Env\fP object on response hook. For each method invocation, user can can access \fBNghttpx::Request\fP and \fBNghttpx::Response\fP objects via \fBNghttpx::Env#req\fP and \fBNghttpx::Env#resp\fP respectively. .INDENT 0.0 .TP .B Nghttpx::REQUEST_PHASE Constant to represent request phase. .UNINDENT .INDENT 0.0 .TP .B Nghttpx::RESPONSE_PHASE Constant to represent response phase. .UNINDENT .INDENT 0.0 .TP .B class Nghttpx::Env Object to represent current request specific context. .INDENT 7.0 .TP .B attribute [R] req Return \fBRequest\fP object. .UNINDENT .INDENT 7.0 .TP .B attribute [R] resp Return \fBResponse\fP object. .UNINDENT .INDENT 7.0 .TP .B attribute [R] ctx Return Ruby hash object.

On assignment, copy of given value is assigned. The path does not include authority component of URI. This may include query component. nghttpx makes certain normalization for path. It decodes percent\-encoding for unreserved characters (see \%), and resolves \(dq..\(dq and \(dq.\(dq. But it may leave characters which should be percent\-encoded as is. So be careful when comparing path against desired string. .UNINDENT .INDENT 7.0 .TP .B attribute [R] headers Return Ruby hash containing copy of request header fields. Changing values in returned hash does not change request header fields actually used in request processing.

When this method is called in request phase hook, the request is not forwarded to the backend, and response phase hook for this request will not be invoked. When this method is called in response phase hook, response from backend server is canceled and discarded. The status code and response header fields should be set before using this method. To set status code, use \fBNghttpx::Response#status\fP\&. If status code is not set, 200 is used. To set response header fields, \fBNghttpx::Response#add_header\fP and \fBNghttpx::Response#set_header\fP\&. When this method is invoked in response phase hook, the response headers are filled with the ones received from backend server. To send completely custom header fields, first call \fBNghttpx::Response#clear_headers\fP to erase all existing header fields, and then add required header fields. It is an error to call this method twice for a given request. .UNINDENT .INDENT 7.0 .TP .B send_info(status, headers) Send non\-final (informational) response to a client. \fIstatus\fP must be in the range [100, 199], inclusive. \fIheaders\fP is a hash containing response header fields. Its key must be a string, and the associated value must be either string or array of strings. Since this is not a final response, even if this method is invoked, request is still forwarded to a backend unless \fBNghttpx::Response#return\fP is called. This method can be called multiple times. It cannot be called after \fBNghttpx::Response#return\fP is called. .UNINDENT .UNINDENT .SS MRUBY EXAMPLES .sp Modify request path: .INDENT 0.0 .INDENT 3.5 .sp .EX class App def on_req(env) env.req.path = \(dq/apps#{env.req.path}\(dq end end App.new .EE .UNINDENT .UNINDENT .sp Don\(aqt forget to instantiate and evaluate object at the last line. .sp Restrict permission of viewing a content to a specific client addresses: .INDENT 0.0 .INDENT 3.5 .sp .EX class App def on_req(env) allowed_clients = [\(dq127.0.0.1\(dq, \(dq::1\(dq] if env.req.path.start_with?(\(dq/log/\(dq) && !allowed_clients.include?(env.remote_addr) then env.resp.status = 404 env.resp.return \(dqpermission denied\(dq end end end App.new .EE .UNINDENT .UNINDENT .SH API ENDPOINTS .sp nghttpx exposes API endpoints to manipulate it via HTTP based API. By default, API endpoint is disabled. To enable it, add a dedicated frontend for API using \fB\-\-frontend\fP option with \(dqapi\(dq parameter. All requests which come from this frontend address, will be treated as API request. .sp The response is normally JSON dictionary, and at least includes the following keys: .INDENT 0.0 .TP .B status The status of the request processing. The following values are defined: .INDENT 7.0 .TP .B Success The request was successful. .TP .B Failure The request was failed. No change has been made. .UNINDENT .TP .B code HTTP status code .UNINDENT .sp Additionally, depending on the API endpoint, \fBdata\fP key may be present, and its value contains the API endpoint specific data. .sp We wrote \(dqnormally\(dq, since nghttpx may return ordinal HTML response in some cases where the error has occurred before reaching API endpoint (e.g., header field is too large). .sp The following section describes available API endpoints. .SS POST /api/v1beta1/backendconfig .sp This API replaces the current backend server settings with the requested ones. The request method should be POST, but PUT is also acceptable. The request body must be nghttpx configuration file format. For configuration file format, see FILES section. The line separator inside the request body must be single LF (0x0A). Currently, only \fBbackend\fP option is parsed, the others are simply ignored. The semantics of this API is replace the current backend with the backend options in request body. Describe the desired set of backend severs, and nghttpx makes it happen. If there is no \fBbackend\fP option is found in request body, the current set of backend is replaced with the \fBbackend\fP option\(aqs default value, which is \fB127.0.0.1,80\fP\&. .sp The replacement is done instantly without breaking existing connections or requests. It also avoids any process creation as is the case with hot swapping with signals. .sp The one limitation is that only numeric IP address is allowed in \fBbackend\fP in request body unless \(dqdns\(dq parameter is used while non numeric hostname is allowed in command\-line or configuration file is read using \fB\-\-conf\fP\&. .SS GET /api/v1beta1/configrevision .sp This API returns configuration revision of the current nghttpx. The configuration revision is opaque string, and it changes after each reloading by SIGHUP. With this API, an external application knows that whether nghttpx has finished reloading its configuration by comparing the configuration revisions between before and after reloading. It is recommended to disable persistent (keep\-alive) connection for this purpose in order to avoid to send a request using the reused connection which may bound to an old process. .sp This API returns response including \fBdata\fP key. Its value is JSON object, and it contains at least the following key: .INDENT 0.0 .TP .B configRevision The configuration revision of the current nghttpx .UNINDENT .SH SEE ALSO .sp \fBnghttp(1)\fP, \fBnghttpd(1)\fP, \fBh2load(1)\fP .SH Author Tatsuhiro Tsujikawa .SH Copyright 2012, 2015, 2016, Tatsuhiro Tsujikawa .\" End of generated man page. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_hd_deflate_get_table_entry.rst0000644000000000000000000000013115232371110022510 xustar0029 mtime=1785328200.98555963 30 atime=1785328201.063793174 30 ctime=1785328204.525340704 nghttp2-1.70.0/doc/nghttp2_hd_deflate_get_table_entry.rst0000644000175100017510000000116715232371110023106 0ustar00runnerrunner nghttp2_hd_deflate_get_table_entry ================================== Synopsis -------- *#include * .. function:: const nghttp2_nv * nghttp2_hd_deflate_get_table_entry(nghttp2_hd_deflater *deflater, size_t idx) Returns the table entry denoted by *idx* from header table of *deflater*.

Required unless \fB\-\-no\-tls\fP is specified. .UNINDENT .INDENT 0.0 .TP .B Set path to server\(aqs certificate. Required unless \fB\-\-no\-tls\fP is specified. .UNINDENT .SH OPTIONS .INDENT 0.0 .TP .B \-a, \-\-address= The address to bind to. If not specified the default IP address determined by getaddrinfo is used. .UNINDENT .INDENT 0.0 .TP .B \-D, \-\-daemon Run in a background. If \fB\-D\fP is used, the current working directory is changed to \(aq\fI/\fP\(aq. Therefore if this option is used, \fB\-d\fP option must be specified. .UNINDENT .INDENT 0.0 .TP .B \-V, \-\-verify\-client The server sends a client certificate request. If the client did not return a certificate, the handshake is terminated. Currently, this option just requests a client certificate and does not verify it. .UNINDENT .INDENT 0.0 .TP .B \-d, \-\-htdocs= Specify document root. If this option is not specified, the document root is the current working directory. .UNINDENT .INDENT 0.0 .TP .B \-v, \-\-verbose Print debug information such as reception/ transmission of frames and name/value pairs. .UNINDENT .INDENT 0.0 .TP .B \-\-no\-tls Disable SSL/TLS. .UNINDENT .INDENT 0.0 .TP .B \-c, \-\-header\-table\-size= Specify decoder header table size. .UNINDENT .INDENT 0.0 .TP .B \-\-encoder\-header\-table\-size= Specify encoder header table size. The decoder (client) specifies the maximum dynamic table size it accepts. Then the negotiated dynamic table size is the minimum of this option value and the value which client specified. .UNINDENT .INDENT 0.0 .TP .B \-\-color Force colored log output. .UNINDENT .INDENT 0.0 .TP .B \-p, \-\-push== Push resources s when is requested. This option can be used repeatedly to specify multiple push configurations. and s are relative to document root. See \fB\-\-htdocs\fP option.

This function receives as many frames as possible until the user callback :type:`nghttp2_recv_callback` returns :enum:`nghttp2_error.NGHTTP2_ERR_WOULDBLOCK`. This function calls several callback functions which are passed when initializing the *session*. Here is the simple time chart which tells when each callback is invoked: 1. :type:`nghttp2_recv_callback` is invoked one or more times to receive frame header. 2. When frame header is received, :type:`nghttp2_on_begin_frame_callback` is invoked. 3. If the frame is DATA frame: 1. :type:`nghttp2_recv_callback` is invoked to receive DATA payload. For each chunk of data, :type:`nghttp2_on_data_chunk_recv_callback` is invoked. 2. If one DATA frame is completely received, :type:`nghttp2_on_frame_recv_callback` is invoked. If the reception of the frame triggers the closure of the stream, :type:`nghttp2_on_stream_close_callback` is invoked. 4. If the frame is the control frame: 1. :type:`nghttp2_recv_callback` is invoked one or more times to receive whole frame. 2. If the received frame is valid, then following actions are taken. If the frame is either HEADERS or PUSH_PROMISE, :type:`nghttp2_on_begin_headers_callback` is invoked. Then :type:`nghttp2_on_header_callback` is invoked for each header name/value pair. For invalid header field, :type:`nghttp2_on_invalid_header_callback` is called. After all name/value pairs are emitted successfully, :type:`nghttp2_on_frame_recv_callback` is invoked. For other frames, :type:`nghttp2_on_frame_recv_callback` is invoked. If the reception of the frame triggers the closure of the stream, :type:`nghttp2_on_stream_close_callback` is invoked. 3. If the received frame is unpacked but is interpreted as invalid, :type:`nghttp2_on_invalid_frame_recv_callback` is invoked. This function returns 0 if it succeeds, or one of the following negative error codes: :enum:`nghttp2_error.NGHTTP2_ERR_EOF` The remote peer did shutdown on the connection. :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE` The callback function failed. :enum:`nghttp2_error.NGHTTP2_ERR_BAD_CLIENT_MAGIC` Invalid client magic was detected. This error only returns when *session* was configured as server and `nghttp2_option_set_no_recv_client_magic()` is not used with nonzero value. :enum:`nghttp2_error.NGHTTP2_ERR_FLOODED` Flooding was detected in this HTTP/2 session, and it must be closed. This is most likely caused by misbehaviour of peer. nghttp2-1.70.0/doc/PaxHeaders/nghttp2_pack_settings_payload.rst0000644000000000000000000000013115232371110021551 xustar0030 mtime=1785328200.987340529 30 atime=1785328201.121793899 29 ctime=1785328204.58265191 nghttp2-1.70.0/doc/nghttp2_pack_settings_payload.rst0000644000175100017510000000237415232371110022150 0ustar00runnerrunner nghttp2_pack_settings_payload ============================= Synopsis -------- *#include * .. function:: ssize_t nghttp2_pack_settings_payload( uint8_t *buf, size_t buflen, const nghttp2_settings_entry *iv, size_t niv) .. warning:: Deprecated.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The 'configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a 'Makefile' in each directory of the package. It may also create one or more '.h' files containing system-dependent definitions. Finally, it creates a shell script 'config.status' that you can run in the future to recreate the current configuration, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how 'configure' could check whether to do them, and mail diffs or instructions to the address given in the 'README' so they can be considered for the next release. If you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' if you want to change it or regenerate 'configure' using a newer version of 'autoconf'. The simplest way to compile this package is: 1. 'cd' to the directory containing the package's source code and type './configure' to configure the package for your system. Running 'configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type 'make' to compile the package. 3. Optionally, type 'make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing 'make clean'. To also remove the files that 'configure' created (so you can compile the package for a different kind of computer), type 'make distclean'. There is also a 'make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU 'make'. 'cd' to the directory where you want the object files and executables to go and run the 'configure' script. 'configure' automatically checks for the source code in the directory that 'configure' is in and in '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use 'make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' to specify different values for particular kinds of files. Run 'configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving 'configure' the option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. Some packages pay attention to '--enable-FEATURE' options to 'configure', where FEATURE indicates an optional part of the package. They may also pay attention to '--with-PACKAGE' options, where PACKAGE is something like 'gnu-as' or 'x' (for the X Window System). The 'README' should mention any '--enable-' and '--with-' options that the package recognizes. For packages that use the X Window System, 'configure' can usually find the X include and library files automatically, but if it doesn't, you can use the 'configure' options '--x-includes=DIR' and '--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same timestamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file 'config.sub' for the possible values of each field. If 'config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. Sharing Defaults ================ If you want to set default values for 'configure' scripts to share, you can create a site shell script called 'config.site' that gives default values for variables like 'CC', 'cache_file', and 'prefix'. 'configure' looks for 'PREFIX/share/config.site' if it exists, then 'PREFIX/etc/config.site' if it exists. Or, you can set the 'CONFIG_SITE' environment variable to the location of the site script. A warning: not all 'configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--quiet' '--silent' '-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to '/dev/null' (any error messages will still be shown). '--srcdir=DIR' Look for the package's source code in directory DIR. Usually 'configure' can determine that directory automatically.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Likewise, stream-write-timeout sets both frontend-stream-write-timeout and backend-stream-write-timeout. commit e59b8047bd39d096c70a7002f1c52fc5de4692ad Author: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> AuthorDate: 2026-06-08 Commit: GitHub CommitDate: 2026-06-08 build(deps): bump github.com/quic-go/quic-go from 0.59.1 to 0.60.0 Bumps [github.com/quic-go/quic-go](https://github.com/quic-go/quic-go) from 0.59.1 to 0.60.0. - [Release notes](https://github.com/quic-go/quic-go/releases) - [Commits](https://github.com/quic-go/quic-go/compare/v0.59.1...v0.60.0) --- updated-dependencies: - dependency-name: github.com/quic-go/quic-go dependency-version: 0.60.0 dependency-type: direct:production update-type: version-update:semver-minor ...

The multiple backend addresses are accepted by repeating this option. UNIX domain socket can be specified by prefixing path name with "unix:" (e.g., unix:/var/run/backend.sock). Optionally, if s are given, the backend address is only used if request matches the pattern. The pattern matching is closely designed to ServeMux in net/http package of Go programming language. consists of path, host + path or just host. The path must start with "/". If it ends with "/", it matches all request path in its subtree. To deal with the request to the directory without trailing slash, the path which ends with "/" also matches the request path which only lacks trailing '/' (e.g., path "/foo/" matches request path "/foo"). If it does not end with "/", it performs exact match against the request path. If host is given, it performs a match against the request host. For a request received on the frontend listener with "sni-fwd" parameter enabled, SNI host is used instead of a request host. If host alone is given, "/" is appended to it, so that it matches all request paths under the host (e.g., specifying "nghttp2.org" equals to "nghttp2.org/"). CONNECT method is treated specially. It does not have path, and we don't allow empty path. To workaround this, we assume that CONNECT method has "/" as path. Patterns with host take precedence over patterns with just path. Then, longer patterns take precedence over shorter ones. Host can include "*" in the left most position to indicate wildcard match (only suffix match is done). The "*" must match at least one character. For example, host pattern "*.nghttp2.org" matches against "www.nghttp2.org" and "git.ngttp2.org", but does not match against "nghttp2.org". The exact hosts match takes precedence over the wildcard hosts match. If path part ends with "*", it is treated as wildcard path. The wildcard path behaves differently from the normal path. For normal path, match is made around the boundary of path component separator,"/". On the other hand, the wildcard path does not take into account the path component separator. All paths which include the wildcard path without last "*" as prefix, and are strictly longer than wildcard path without last "*" are matched. "*" must match at least one character. For example, the pattern "/foo*" matches "/foo/" and "/foobar". But it does not match "/foo", or "/fo". If is omitted or empty string, "/" is used as pattern, which matches all request paths (catch-all pattern). The catch-all backend must be given. When doing a match, nghttpx made some normalization to pattern, request host and path. For host part, they are converted to lower case. For path part, percent-encoded unreserved characters defined in RFC 3986 are decoded, and any dot-segments (".." and ".") are resolved and removed. For example, -b'127.0.0.1,8080;nghttp2.org/httpbin/' matches the request host "nghttp2.org" and the request path "/httpbin/get", but does not match the request host "nghttp2.org" and the request path "/index.html". The multiple s can be specified, delimiting them by ":". Specifying -b'127.0.0.1,8080;nghttp2.org:www.nghttp2.org' has the same effect to specify -b'127.0.0.1,8080;nghttp2.org' and -b'127.0.0.1,8080;www.nghttp2.org'. The backend addresses sharing same are grouped together forming load balancing group. Several parameters are accepted after . The parameters are delimited by ";". The available parameters are: "proto=", "tls", "sni=", "fall=", "rise=", "affinity=", "dns", "redirect-if-not-tls", "upgrade-scheme", "mruby=", "read-timeout=", "write-timeout=", "group=", "group-weight=", "weight=", and "dnf". The parameter consists of keyword, and optionally followed by "=" and value. For example, the parameter "proto=h2" consists of the keyword "proto" and value "h2". The parameter "tls" consists of the keyword "tls" without value. Each parameter is described as follows. The backend application protocol can be specified using optional "proto" parameter, and in the form of "proto=". should be one of the following list without quotes: "h2", "http/1.1". The default value of is "http/1.1". Note that usually "h2" refers to HTTP/2 over TLS. But in this option, it may mean HTTP/2 over cleartext TCP unless "tls" keyword is used (see below). TLS can be enabled by specifying optional "tls" parameter. TLS is not enabled by default. With "sni=" parameter, it can override the TLS SNI field value with given . This will default to the backend name The feature to detect whether backend is online or offline can be enabled using optional "fall" and "rise" parameters. Using "fall=" parameter, if nghttpx cannot connect to a this backend times in a row, this backend is assumed to be offline, and it is excluded from load balancing. If is 0, this backend never be excluded from load balancing whatever times nghttpx cannot connect to it, and this is the default. There is also "rise=" parameter. After backend was excluded from load balancing group, nghttpx periodically attempts to make a connection to the failed backend, and if the connection is made successfully times in a row, the backend is assumed to be online, and it is now eligible for load balancing target. If is 0, a backend is permanently offline, once it goes in that state, and this is the default behaviour. The session affinity is enabled using "affinity=" parameter. If "ip" is given in , client IP based session affinity is enabled. If "cookie" is given in , cookie based session affinity is enabled. If "none" is given in , session affinity is disabled, and this is the default. The session affinity is enabled per . If at least one backend has "affinity" parameter, and its is not "none", session affinity is enabled for all backend servers sharing the same . It is advised to set "affinity" parameter to all backend explicitly if session affinity is desired. The session affinity may break if one of the backend gets unreachable, or backend settings are reloaded or replaced by API. If "affinity=cookie" is used, the additional configuration is required. "affinity-cookie-name=" must be used to specify a name of cookie to use. Optionally, "affinity-cookie-path=" can be used to specify a path which cookie is applied. The optional "affinity-cookie-secure=" controls the Secure attribute of a cookie. The default value is "auto", and the Secure attribute is determined by a request scheme. If a request scheme is "https", then Secure attribute is set. Otherwise, it is not set. If is "yes", the Secure attribute is always set. If is "no", the Secure attribute is always omitted. "affinity-cookie-stickiness=" controls stickiness of this affinity. If is "loose", removing or adding a backend server might break the affinity and the request might be forwarded to a different backend server. If is "strict", removing the designated backend server breaks affinity, but adding new backend server does not cause breakage. If the designated backend server becomes unavailable, new backend server is chosen as if the request does not have an affinity cookie. defaults to "loose". By default, name resolution of backend host name is done at start up, or reloading configuration. If "dns" parameter is given, name resolution takes place dynamically. This is useful if backend address changes frequently. If "dns" is given, name resolution of backend host name at start up, or reloading configuration is skipped. If "redirect-if-not-tls" parameter is used, the matched backend requires that frontend connection is TLS encrypted. If it isn't, nghttpx responds to the request with 308 status code, and https URI the client should use instead is included in Location header field. The port number in redirect URI is 443 by default, and can be changed using --redirect-https-port option. If at least one backend has "redirect-if-not-tls" parameter, this feature is enabled for all backend servers sharing the same . It is advised to set "redirect-if-no-tls" parameter to all backends explicitly if this feature is desired. If "upgrade-scheme" parameter is used along with "tls" parameter, HTTP/2 :scheme pseudo header field is changed to "https" from "http" when forwarding a request to this particular backend. This is a workaround for a backend server which requires "https" :scheme pseudo header field on TLS encrypted connection. "mruby=" parameter specifies a path to mruby script file which is invoked when this pattern is matched. All backends which share the same pattern must have the same mruby path. "read-timeout=" and "write-timeout=" parameters specify the read and write timeout of the backend connection when this pattern is matched. All backends which share the same pattern must have the same timeouts. If these timeouts are entirely omitted for a pattern, --backend-read-timeout and --backend-write-timeout are used. "group=" parameter specifies the name of group this backend address belongs to. By default, it belongs to the unnamed default group. The name of group is unique per pattern. "group-weight=" parameter specifies the weight of the group. The higher weight gets more frequently selected by the load balancing algorithm. must be [1, 256] inclusive. The weight 8 has 4 times more weight than 2. must be the same for all addresses which share the same . If "group-weight" is omitted in an address, but the other address which belongs to the same group specifies "group-weight", its weight is used. If no "group-weight" is specified for all addresses, the weight of a group becomes 1. "group" and "group-weight" are ignored if session affinity is enabled. "weight=" parameter specifies the weight of the backend address inside a group which this address belongs to. The higher weight gets more frequently selected by the load balancing algorithm. must be [1, 256] inclusive. The weight 8 has 4 times more weight than weight 2. If this parameter is omitted, weight becomes 1. "weight" is ignored if session affinity is enabled. If "dnf" parameter is specified, an incoming request is not forwarded to a backend and just consumed along with the request body (actually a backend server never be contacted). It is expected that the HTTP response is generated by mruby script (see "mruby=" parameter above). "dnf" is an abbreviation of "do not forward".

Options: -v, --verbose Print debug information such as reception and transmission of frames and name/value pairs.

If URI ends with '/', 'index.html' is used as a filename. Not implemented yet. -t, --timeout= Timeout each request after . Set 0 to disable timeout. -w, --window-bits= Sets the stream level initial window size to 2**-1. -W, --connection-window-bits= Sets the connection level initial window size to 2**-1. -a, --get-assets Download assets such as stylesheets, images and script files linked from the downloaded resource. Only links whose origins are the same with the linking resource will be downloaded. nghttp prioritizes resources using HTTP/2 dependency based priority. The priority order, from highest to lowest, is html itself, css, javascript and images. -s, --stat Print statistics. -H, --header=
Add a header to the requests. Example: -H':method: PUT' --trailer=
Add a trailer header to the requests.
must not include pseudo header field (header field name starting with ':'). To send trailer, one must use -d option to send request body. Example: --trailer 'foo: bar'. --cert= Use the specified client certificate file. The file must be in PEM format. --key= Use the client private key file. The file must be in PEM format. -d, --data= Post FILE to server. If '-' is given, data will be read from stdin. -m, --multiply= Request each URI times. By default, same URI is not requested twice. This option disables it too. -u, --upgrade Perform HTTP Upgrade for HTTP/2. This option is ignored if the request URI has https scheme. If -d is used, the HTTP upgrade request is performed with OPTIONS method. --extpri= Sets RFC 9218 priority of given URI. must be the wire format of priority header field (e.g., "u=3,i"). This option can be used multiple times, and N-th --extpri option sets priority of N-th URI in the command line. If the number of this option is less than the number of URI, the last option value is repeated. If there is no --extpri option, urgency is 3, and incremental is false. -M, --peer-max-concurrent-streams= Use as SETTINGS_MAX_CONCURRENT_STREAMS value of remote endpoint as if it is received in SETTINGS frame. Default: 100 -c, --header-table-size= Specify decoder header table size. If this option is used multiple times, and the minimum value among the given values except for last one is strictly less than the last value, that minimum value is set in SETTINGS frame payload before the last value, to simulate multiple header table size change. --encoder-header-table-size= Specify encoder header table size. The decoder (server) specifies the maximum dynamic table size it accepts. Then the negotiated dynamic table size is the minimum of this option value and the value which server specified. -b, --padding= Add at most bytes to a frame payload as padding. Specify 0 to disable padding. -r, --har= Output HTTP transactions in HAR format. If '-' is given, data is written to stdout. --color Force colored log output. --continuation Send large header to test CONTINUATION. --no-content-length Don't send content-length header field. --hexdump Display the incoming traffic in hexadecimal (Canonical hex+ASCII display). If SSL/TLS is used, decrypted data are used. --no-push Disable server push. --max-concurrent-streams= The number of concurrent pushed streams this client accepts. --expect-continue Perform an Expect/Continue handshake: wait to send DATA (up to a short timeout) until the server sends a 100 Continue interim response. This option is ignored unless combined with the -d option. -y, --no-verify-peer Suppress warning on server certificate verification failure. --ktls Enable ktls. --version Display version information and exit. -h, --help Display this help and exit. -- The argument is an integer and an optional unit (e.g., 10K is 10 * 1024).

Install MinGW; 64-bit target seems to work best. # # 2. Install Wine. # # 3. Run command: # # wine cmd /c echo "Hello world"' # # This will confirm that Wine works and will trigger standard # Wine setup, which is slow. # # 4. Confirm that drive 'z:' is mapped to your root filesystem. # (This is supposed to be a default but it helps to # double-check.) To confirm, run: # # wine cmd /c dir 'z:\\' # # This should give you a DOS-style equivalent of 'ls /'. If not, # you'll need to fix that with winecfg or by adding a symlink to # '~/.wine/dosdevices'. # # 5. You will likely need to tweak the settings below to work with # your configuration unless it is exactly like one of the platforms # I've tested on (Ubuntu 20.04 or macOS using brew.) # # 6. Run the build command: # # MRUBY_CONFIG=build_config/cross-mingw-winetest.rb rake test # # If all goes well, you should now have Windows executables and a # set of passing tests. # # # Caveats: # # 1. This works by using a helper script that rewrites test output # to make it look *nix-like and then handing it back to the test # cases. Some of the existing tests were (slightly) modified to # make this easier but only for the 'full-core' gembox. Other # gems' bintests may or may not work with the helper script and # may or may not be fixable by extending the script. # # 2. MinGW and Wine are both complex and not very consistent so you # will likely need to do some fiddling to get things to work. # # 3. This script assumes you are running it on a *nix-style OS. # # 4.

This file is placed for the purpose of describing hints for creating a `mruby-bigint` compatible GEM to realize multiple integers. The file structure in this example is as follows: ``` +- mruby-YOUR-bigint/ <- Make this directory public if necessary. | Change the name of copied directory. | +- TODO-HINT.md <- You are currently viewing this file. | Remove this from copied directory. | +- core/ | | | +- bigint.c <- Body of the implementation. | +- mrbgem.rake <- GEM name is "mruby-bigint". May be depended on by other GEMs. ``` Implementers of their own bigints should copy below this directory to another directory and do the following: - Rewrite `spec.author`, `spec.license`, `spec.homepage` and `spec.summary` in `/mrbgem.rake` file to those of your own implementers. - Implement the respective functions in `/core/bigint.c`. - Define and use an object structure for `MRB_TT_BIGINT` type-tag. It is recommended to use `mrb_static_assert_object_size()` to ensure that the size of the object structure is within six words. - Delete this file from the destination of the copy. If you wish to use it as an alternative to the `mruby-bigint` provided by mruby, please leave the GEM name in `/mrbgem.rake` as it is. This is an important factor when it is depended from other GEMs with `spec.add_dependency 'mruby-bigint'`. The name of the top directory of the GEM can be changed arbitrarily. The name of the Git repository can also be changed arbitrarily. Note that there is no need for an initialization function as there is in a normal GEM. If you need it, create a file `/src/bigint.c` for example, and implement the `mrb_mruby_bigint_gem_init()` function.

0ustar00runnerrunner# How to contribute mruby is an open-source project which is looking forward to each contribution. Contributors agree to license their contribution(s) under MIT license. ## Your Pull Request To make it easy to review and understand your change please keep the following things in mind before submitting your pull request: - Work on the latest possible state of **mruby/master** - Create a branch which is dedicated to your change - Test your changes before creating a pull request (`rake test`) - If possible write a test case which confirms your change - Don't mix several features or bugfixes in one pull request - Create a meaningful commit message - Explain your change (i.e. with a link to the issue you are fixing) - Use mrbgem to provide non ISO features (classes, modules and methods) unless you have a special reason to implement them in the core ## Security Issues If you discover a security vulnerability: - **High priority security vulnerabilities** (RCE): Report via email to - **VM crashes from valid Ruby code**: Please report as regular bug reports on our issue tracker For detailed guidance on what qualifies as a security issue and what doesn't, see [SECURITY.md](SECURITY.md). ## prek We use [prek](https://github.com/j178/prek), a fast Rust-based pre-commit hook manager. It reads the standard `.pre-commit-config.yaml` format. Install `prek` following the [installation guide](https://github.com/j178/prek#installation), then install the hooks with `prek install`. Now `prek` will run automatically on git commit! It's usually a good idea to run the hooks against all the files when adding new hooks (usually `prek` will only run on the changed files during git hooks). Use `prek run --all-files` to check all files. To run a single hook use `prek run --all-files ` To update use `prek autoupdate` Sometimes you might need to skip one or more hooks which can be done with the `SKIP` environment variable. `$ SKIP=yamllint git commit -m "foo"` For convenience, we have added `prek run --all-files`, `prek install` and `prek autoupdate` to both the Makefile and the Rakefile. Run them with: - `make check` or `rake check` - `make checkinstall` or `rake checkinstall` - `make checkupdate` or `rake checkupdate` To configure hooks you can modify the config file [.pre-commit-config.yaml](.pre-commit-config.yaml). We use [GitHub Actions](.github/workflows/pre-commit.yml) to run `prek` on every pull request. ### prek quick links - [prek GitHub](https://github.com/j178/prek) - [Installation](https://github.com/j178/prek#installation) - [Usage](https://github.com/j178/prek#usage) ## Docker We have both a `Dockerfile` and `docker-compose.yml` files in the repository root. You can run these with the command line or use [Docker Desktop](https://www.docker.com/products/docker-desktop/). The Docker image is running Debian bullseye with Ruby and Python installed. You can build the Docker image with: `$ docker-compose build test` So far we just have one service: `test`. Running the default `docker-compose` command will create the Docker image, spin up a container and then build and run all mruby tests. The default `docker-compose` command is: `$ docker-compose -p mruby run test` You can also use Make or Rake to run the default `docker-compose` command from above: - `make composetest` - `rake composetest` List your Docker images with: ```console $ docker images REPOSITORY TAG IMAGE ID CREATED SIZE mruby-test latest ec60f9536948 29 seconds ago 1.29GB ``` You can also run any custom `docker-compose` command which will override the default. For example to run `prek run --all-files` type: `$ docker-compose -p mruby run test prek run --all-files` For convenience, you can also run `prek` with: - `make composecheck` - `rake composecheck` The bonus of running `prek` with `docker-compose` is that you won't need to install `prek` and the hooks on your local machine. Note limitation: currently running `prek` with `docker-compose` we skip the `check-executables-have-shebangs` hook. Two more examples of custom `docker-compose` commands are: - `$ docker-compose -p mruby run test ls` - `$ docker-compose -p mruby run test rake doc:api` If you want to test using a different `docker-compose` YAML config file you can use the `-f` flag: `$ docker-compose -p mruby -f docker-compose.test.yml run test` - - ## Spell Checking We are using `prek` to run [codespell](https://github.com/codespell-project/codespell) to check code for common misspellings. We have a small custom dictionary file [codespell.txt](.github/linters/codespell.txt). ## Coding conventions How to style your C and Ruby code which you want to submit. ### C code The core part (parser, bytecode-interpreter, core-lib, etc.) of mruby is written in the C programming language. Please note the following hints for your C code: #### Comply with C99 (ISO/IEC 9899:1999) mruby should be highly portable to other systems and compilers. For this it is recommended to keep your code as close as possible to the C99 standard (). Visual C++ is also an important target for mruby (supported version is 2013 or later). For this reason features that are not supported by Visual C++ may not be used (e.g. `%z` of `strftime()`). NOTE: Old GCC requires `-std=gnu99` option to enable C99 support. #### Reduce library dependencies to a minimum The dependencies to libraries should be kept to an absolute minimum. This increases the portability but makes it also easier to cut away parts of mruby on-demand. #### Insert a break after the function return value: ```c int main(void) { ... } ``` ### Ruby code Parts of the standard library of mruby are written in the Ruby programming language itself. Please note the following hints for your Ruby code: #### Comply with the Ruby standard (ISO/IEC 30170:2012) mruby is currently targeting to execute Ruby code which complies to ISO/IEC 30170:2012 (), unless there's a clear reason, e.g. the latest Ruby has changed behavior from ISO. ## Building documentation ### mruby API - [YARD](https://yardoc.org/) - YARD is a documentation generation tool for the Ruby programming language - [yard-mruby](https://rubygems.org/gems/yard-mruby) - Document mruby sources with YARD - [yard-coderay](https://rubygems.org/gems/yard-coderay) - Adds coderay syntax highlighting to YARD docs ### C API - [Doxygen](https://www.doxygen.nl/) - Generate documentation from source code - [Graphviz](https://graphviz.org/) - Graphviz is open source graph visualization software nghttp2-1.70.0/third-party/mruby/PaxHeaders/doc0000644000000000000000000000012715232371113016342 xustar0029 mtime=1785328203.91519417 29 atime=1785328204.81885618 29 ctime=1785328203.91519417 nghttp2-1.70.0/third-party/mruby/doc/0000755000175100017510000000000015232371113017003 5ustar00runnerrunnernghttp2-1.70.0/third-party/mruby/doc/PaxHeaders/mruby3.3.md0000644000000000000000000000013215232371065020325 xustar0030 mtime=1785328181.914511146 30 atime=1785328183.362518374 30 ctime=1785328203.916570297 nghttp2-1.70.0/third-party/mruby/doc/mruby3.3.md0000644000175100017510000004052315232371065020721 0ustar00runnerrunner# User visible changes in `mruby3.3` from `mruby3.2` "**_NOTE_**:" are changes to be aware of. # The language - aliases work properly with `super` ([2ad3f0e](https://github.com/mruby/mruby/commit/2ad3f0e)) - `callee` method work differently with aliases in mruby ([f2dc76e](https://github.com/mruby/mruby/commit/f2dc76e)) - define `Kernel#respond_to_missing?` method ([347586e](https://github.com/mruby/mruby/commit/347586e)) - `_inspect` method (`inspect` with recursive check) is removed ([e2bbf75](https://github.com/mruby/mruby/commit/e2bbf75), [5cb0c74](https://github.com/mruby/mruby/commit/5cb0c74), [113565a](https://github.com/mruby/mruby/commit/113565a), [0713f2a](https://github.com/mruby/mruby/commit/0713f2a), [6ae6b63](https://github.com/mruby/mruby/commit/6ae6b63), [fc9fffc](https://github.com/mruby/mruby/commit/fc9fffc)) - `__printstr__` method is removed; use `print` instead ([acecee0](https://github.com/mruby/mruby/commit/acecee0), [192e6e3](https://github.com/mruby/mruby/commit/192e6e3)) - New method `String#bytesplice` ([5274647](https://github.com/mruby/mruby/commit/5274647), [a2e2e83](https://github.com/mruby/mruby/commit/a2e2e83)) - Allow `return` in blocks to cross C boundaries ([#6125](https://github.com/mruby/mruby/pull/6125)) # Configuration - mruby can be built using Docker now.

Each instruction is a single byte, allowing up to 256 opcodes. Instructions can take 0 to 3 operands. ## Operands The size of operands can be either 8 bits, 16 bits, or 24 bits. In the instruction table below, the operand type field describes the size of each operand. - `Z`: no operand - `B`: 8 bits - `S`: 16 bits - `W`: 24 bits If the first and second operands are of type `B` (8 bits), they may be extended to 16 bits by the operand extension instruction immediately preceding them. See also `OP_EXT1`, `OP_EXT2` and `OP_EXT3`. ## Instruction Table | No. | Instruction Name | Operand type | Semantics | | --: | ---------------- | ------------ | ----------------------------------------------------------------- | | 0 | `OP_NOP` | `Z` | no operation | | 1 | `OP_MOVE` | `BB` | `R[a] = R[b]` | | 2 | `OP_LOADL` | `BB` | `R[a] = Pool[b]` | | 3 | `OP_LOADI8` | `BB` | `R[a] = mrb_int(b)` | | 4 | `OP_LOADINEG` | `BB` | `R[a] = mrb_int(-b)` | | 5 | `OP_LOADI__1` | `B` | `R[a] = mrb_int(-1)` | | 6 | `OP_LOADI_0` | `B` | `R[a] = mrb_int(0)` | | 7 | `OP_LOADI_1` | `B` | `R[a] = mrb_int(1)` | | 8 | `OP_LOADI_2` | `B` | `R[a] = mrb_int(2)` | | 9 | `OP_LOADI_3` | `B` | `R[a] = mrb_int(3)` | | 10 | `OP_LOADI_4` | `B` | `R[a] = mrb_int(4)` | | 11 | `OP_LOADI_5` | `B` | `R[a] = mrb_int(5)` | | 12 | `OP_LOADI_6` | `B` | `R[a] = mrb_int(6)` | | 13 | `OP_LOADI_7` | `B` | `R[a] = mrb_int(7)` | | 14 | `OP_LOADI16` | `BS` | `R[a] = mrb_int(b)` | | 15 | `OP_LOADI32` | `BSS` | `R[a] = mrb_int((b<<16)+c)` | | 16 | `OP_LOADSYM` | `BB` | `R[a] = Syms[b]` | | 17 | `OP_LOADNIL` | `B` | `R[a] = nil` | | 18 | `OP_LOADSELF` | `B` | `R[a] = self` | | 19 | `OP_LOADTRUE` | `B` | `R[a] = true` | | 20 | `OP_LOADFALSE` | `B` | `R[a] = false` | | 21 | `OP_GETGV` | `BB` | `R[a] = getglobal(Syms[b])` | | 22 | `OP_SETGV` | `BB` | `setglobal(Syms[b], R[a])` | | 23 | `OP_GETSV` | `BB` | `R[a] = Special[Syms[b]]` | | 24 | `OP_SETSV` | `BB` | `Special[Syms[b]] = R[a]` | | 25 | `OP_GETIV` | `BB` | `R[a] = ivget(Syms[b])` | | 26 | `OP_SETIV` | `BB` | `ivset(Syms[b],R[a])` | | 27 | `OP_GETCV` | `BB` | `R[a] = cvget(Syms[b])` | | 28 | `OP_SETCV` | `BB` | `cvset(Syms[b],R[a])` | | 29 | `OP_GETCONST` | `BB` | `R[a] = constget(Syms[b])` | | 30 | `OP_SETCONST` | `BB` | `constset(Syms[b],R[a])` | | 31 | `OP_GETMCNST` | `BB` | `R[a] = R[a]::Syms[b]` | | 32 | `OP_SETMCNST` | `BB` | `R[a+1]::Syms[b] = R[a]` | | 33 | `OP_GETUPVAR` | `BBB` | `R[a] = uvget(b,c)` | | 34 | `OP_SETUPVAR` | `BBB` | `uvset(b,c,R[a])` | | 35 | `OP_GETIDX` | `B` | `R[a] = R[a][R[a+1]]` | | 36 | `OP_GETIDX0` | `BB` | `R[a] = R[b][0]` | | 37 | `OP_SETIDX` | `B` | `R[a][R[a+1]] = R[a+2]` | | 38 | `OP_JMP` | `S` | `pc += a` | | 39 | `OP_JMPIF` | `BS` | `if R[a] pc += b` | | 40 | `OP_JMPNOT` | `BS` | `if !R[a] pc += b` | | 41 | `OP_JMPNIL` | `BS` | `if R[a]==nil pc += b` | | 42 | `OP_JMPUW` | `S` | `unwind_and_jump_to(a)` | | 43 | `OP_EXCEPT` | `B` | `R[a] = exc` | | 44 | `OP_RESCUE` | `BB` | `R[b] = R[a].isa?(R[b])` | | 45 | `OP_RAISEIF` | `B` | `raise(R[a]) if R[a]` | | 46 | `OP_MATCHERR` | `B` | `raise NoMatchingPatternError unless R[a]` | | 47 | `OP_SSEND` | `BBB` | `R[a] = self.send(Syms[b],R[a+1]..,R[a+n+1]:R[a+n+2]..)

Common patterns like `attr_reader` methods (`return self.@x`) and predicate methods (`return true`/`return false`) benefit from these specialized opcodes. ### OP_BLKCALL Direct block invocation that bypasses method dispatch. Used when calling a block argument directly (e.g., `yield` or `block.call`). ### OP_ADDILV / OP_SUBILV Optimized integer increment/decrement that keeps operands for method call fallback when the receiver is not a Fixnum. ### OP_TDEF / OP_SDEF Optimized method definition. `OP_TDEF` defines a method on the `target_class` directly from an irep without creating an intermediate `RProc`. `OP_SDEF` does the same for singleton methods. ### OP_MATCHERR Raises `NoMatchingPatternError` when a pattern match fails. Used by the `case`/`in` pattern matching syntax. ### OP_GETIDX / OP_GETIDX0 / OP_SETIDX Optimization These instructions optimize `[]` and `[]=` access for Array, Hash, and String. **OP_GETIDX** uses direct function calls: - `Array`: `mrb_ary_entry()` (integer index only) - `Hash`: `mrb_hash_get()` - `String`: `mrb_str_aref()` (integer/string/range index) **OP_GETIDX0** is a specialized variant for index 0 (e.g., `ary[0]`). **OP_SETIDX** uses direct function calls: - `Array`: `mrb_ary_set()` (integer index only) - `Hash`: `mrb_hash_set()` **Fallback to method dispatch** occurs when: - Object is a subclass (e.g., `MyArray < Array`) - Object has a singleton class (singleton methods defined) - Index type is not supported (e.g., non-integer for Array) This allows subclasses to override `[]`/`[]=` while base classes remain optimized. nghttp2-1.70.0/third-party/mruby/doc/internal/PaxHeaders/gc.md0000644000000000000000000000013215232371065021150 xustar0030 mtime=1785328181.913871842 30 atime=1785328183.361518369 30 ctime=1785328203.905423345 nghttp2-1.70.0/third-party/mruby/doc/internal/gc.md0000644000175100017510000002527415232371065021552 0ustar00runnerrunner # Garbage Collector Internals This document describes the internals of mruby's garbage collector for developers working on `src/gc.c` and related code. **Read this if you are:** modifying core data structures that hold object references (and need to add write barriers), debugging memory leaks or GC-related crashes, tuning GC performance for an embedded target, or working on the GC code itself. **For user-facing GC docs**, see [gc-arena-howto.md](../guides/gc-arena-howto.md) (arena usage in C extensions) and [memory.md](../guides/memory.md) (heap regions). ## Overview mruby uses a **tri-color incremental mark-and-sweep** garbage collector with an optional **generational mode**. The collector runs in small incremental steps between VM instruction execution, avoiding long pauses. ## Tri-Color Model Every heap-allocated object has a color stored in `RBasic::gc_color` (3 bits): | Color | Value | Meaning | | -------------- | ------ | ------------------------------------ | | White (A or B) | 1 or 2 | Unmarked, candidate for collection | | Gray | 0 | Marked, but children not yet scanned | | Black | 4 | Fully marked and scanned | | Red | 7 | Static/ROM object, never collected | The GC uses two white types (A and B) in a flip-flop scheme. At the start of each GC cycle, the meaning of "current white" is flipped by XORing the white bits. This avoids recoloring all live objects at cycle boundaries, which is an O(1) operation instead of O(n). ```c #define is_dead(s, o) \ (((o)->gc_color & other_white_part(s) & GC_WHITES) || \ (o)->tt == MRB_TT_FREE) ``` An object is dead if it still carries the previous cycle's white color. ## Heap Structure ### Heap Pages Objects are allocated from fixed-size heap pages: ```text mrb_heap_page +-- freelist linked list of free slots +-- next next page in heap list +-- free_next next page with free slots +-- old old generation flag (generational mode) +-- region true if carved from a contiguous region +-- objects[MRB_HEAP_PAGE_SIZE] RVALUE array (default 1024) ``` Each page holds `MRB_HEAP_PAGE_SIZE` objects (default 1024). On 64-bit systems, a page is approximately 40 KB (40 bytes per slot). ### RVALUE Union All mruby object types share the same slot size via a C union: ```text RVALUE = union of { RBasic, RObject, RClass, RString, RArray, RHash, RRange, RData, RProc, REnv, RFiber, RException, ... struct { RBasic header; RVALUE *next; } (free slot) } ``` Free slots use the union space for a freelist pointer. ### Freelist Each page maintains a singly-linked freelist of available slots. Allocation pops from the freelist; deallocation during sweep prepends to the freelist. The GC tracks pages with free slots in `gc->free_heaps` for fast allocation. ### Heap Regions For embedded systems with fixed memory banks, `mrb_gc_add_region()` carves heap pages from a user-provided contiguous buffer: ```c static uint8_t heap_buf[64 * 1024]; mrb_gc_add_region(mrb, heap_buf, sizeof(heap_buf)); ``` Region pages are never freed by the GC (even if all objects die). When region pages are exhausted, allocation falls back to `malloc()`. ## GC Phases The GC operates as a three-state machine: ```text GC_STATE_ROOT --> GC_STATE_MARK --> GC_STATE_SWEEP --> GC_STATE_ROOT ``` ### Root Scan (GC_STATE_ROOT) Marks objects directly reachable from the VM: 1. Global variables (`mrb_gc_mark_gv`) 2. GC arena (`gc->arena[0..arena_idx-1]`) 3. All built-in classes (Object, Class, Module, etc.) 4. Top-level self (`mrb->top_self`) 5. Current exception (`mrb->exc`) 6. Execution contexts (VM stacks, call info stacks, active fibers) 7. Task queues (if `MRB_USE_TASK_SCHEDULER` is defined) After root scanning, the white color is flipped. ### Incremental Marking (GC_STATE_MARK) Gray objects are popped from the gray stack and their children marked. Each step processes a limited number of objects: ```text limit = (GC_STEP_SIZE / 100) * step_ratio ``` With default `step_ratio = 200` and `GC_STEP_SIZE = 1024`, the limit is 2048 objects per step. When the gray stack is exhausted, the final marking phase re-marks the arena and global variables to catch objects created during marking, then transitions to sweep. ### Sweep (GC_STATE_SWEEP) Iterates through heap pages. For each object: - If dead (previous cycle's white): call `obj_free()`, return slot to freelist - If alive: paint with current white for the next cycle Sweep is also incremental: `gc->sweeps` tracks the current page position between steps. ## Gray Stack The gray stack is a fixed-size array of object pointers: ```c struct RBasic *gray_stack[MRB_GRAY_STACK_SIZE]; /* default 1024 */ size_t gray_stack_top; mrb_bool gray_overflow; ``` When the stack overflows, `gray_overflow` is set to `TRUE`. During marking, `gc_gray_rescan()` scans the entire heap to find any gray objects that could not be pushed. This guarantees correctness at the cost of a full heap scan. ## Write Barriers During incremental marking, a black (fully marked) object storing a reference to a white (unmarked) object creates a dangerous edge that could lead to premature collection. Write barriers prevent this. ### Field Write Barrier Used when assigning a specific field: ```c mrb_field_write_barrier(mrb, parent, child); ``` If `parent` is black and `child` is white: - During marking or generational mode: paint `child` gray (add to gray stack for scanning) - During sweep: paint `parent` with current white (demote it for next cycle) ### General Write Barrier Used when an object has been modified but the specific child is not known: ```c mrb_write_barrier(mrb, obj); ``` Paints `obj` gray and pushes it onto the gray stack for re-scanning. ## GC Arena The arena protects newly created objects from collection before they are stored in a reachable location. Every `mrb_obj_alloc()` automatically pushes the new object onto the arena. C extensions must save and restore the arena index when creating many temporary objects to prevent arena overflow: ```c int ai = mrb_gc_arena_save(mrb); /* create temporary objects */ mrb_gc_arena_restore(mrb, ai); ``` ### Fixed vs Dynamic Arena - **Dynamic** (default): arena grows by 1.5x when full. Risk of unbounded growth if arena is not properly managed. - **Fixed** (`MRB_GC_FIXED_ARENA`): raises an exception on overflow. Arena size is `MRB_GC_ARENA_SIZE` (default 100). ### Permanent Registration For long-lived C objects that must survive indefinitely: ```c mrb_gc_register(mrb, obj); /* add to permanent root */ mrb_gc_unregister(mrb, obj); /* remove from root */ ``` These store objects in a global array that is always marked as part of the root set. See [gc-arena-howto.md](../guides/gc-arena-howto.md) for detailed usage patterns. ## Generational Mode When enabled (default, unless `MRB_GC_TURN_OFF_GENERATIONAL` is defined), the GC classifies objects into young and old generations. ### Minor GC Only processes young objects. Pages where all objects are old are marked with `page->old = TRUE` and skipped entirely during sweep. Minor GC always runs to completion in a single step. ### Major GC A full mark-and-sweep cycle that processes all objects. Triggered when `gc->live > gc->oldgen_threshold`. Major GC runs incrementally, like the non-generational collector. After a major GC completes, the collector reverts to minor GC mode. The old-generation threshold is recalculated: ```text oldgen_threshold = live_after_mark * MAJOR_GC_INC_RATIO / 100 ``` With `MAJOR_GC_INC_RATIO = 120`, a major GC triggers when live objects exceed 120% of the last major GC's survivors. ### Transitioning Between Modes ```c mrb_gc_generational_mode_set(mrb, TRUE); /* enable */ mrb_gc_generational_mode_set(mrb, FALSE); /* disable */ ``` From Ruby: `GC.generational_mode = true/false`. ## Object Allocation `mrb_obj_alloc()` is the core allocation function: 1. If `MRB_GC_STRESS` is defined, run a full GC 2. If `gc->live >= gc->threshold`, run `mrb_incremental_gc()` 3. Ensure arena has space (`gc_arena_keep`) 4. Pop an object from the freelist of `gc->free_heaps` 5. If no free pages, allocate a new page (`add_heap`) 6. Initialize the object (zero fill, set type and class) 7. Paint with current white color 8. Push onto arena (`gc_protect`) 9. Increment `gc->live` ## Object Freeing `obj_free()` performs type-specific cleanup: - **Objects/Exceptions**: free instance variable tables - **Classes**: free method tables and instance variable tables - **Arrays**: free heap buffer (if not embedded/shared) - **Hashes**: free hash table - **Strings**: free heap buffer (if not embedded/shared) - **Data objects**: call user-provided `dfree` callback - **Procs**: decrement irep reference count - **Fibers**: free context (stacks) The object's type is set to `MRB_TT_FREE` after freeing. ## Triggering GC ### Automatic GC runs automatically when `gc->live >= gc->threshold` during object allocation. After each cycle: ```text threshold = (live_after_mark / 100) * interval_ratio minimum: GC_STEP_SIZE (1024) ``` With default `interval_ratio = 200`, GC triggers when live objects roughly double. ### Manual ```c mrb_full_gc(mrb); /* force complete GC cycle */ mrb_garbage_collect(mrb); /* public API wrapper */ ``` From Ruby: `GC.start`. ## Configuration ### Compile-Time | Macro | Default | Description | | ------------------------------ | ------- | --------------------------------------- | | `MRB_HEAP_PAGE_SIZE` | 1024 | Objects per heap page | | `MRB_GRAY_STACK_SIZE` | 1024 | Gray stack capacity | | `MRB_GC_ARENA_SIZE` | 100 | Arena size (fixed mode) or initial size | | `MRB_GC_FIXED_ARENA` | off | Use fixed-size arena | | `MRB_GC_TURN_OFF_GENERATIONAL` | off | Disable generational mode | | `MRB_GC_STRESS` | off | Full GC on every allocation (debug) | | `MRB_USE_MALLOC_TRIM` | off | Call `malloc_trim()` after full GC | ### Runtime From Ruby code: ```ruby GC.interval_ratio = 200 # threshold = live * ratio / 100 GC.step_ratio = 200 # objects per incremental step GC.generational_mode = true GC.start # force full GC GC.enable # re-enable GC GC.disable # disable GC ``` ## Source Files | File | Contents | | -------------------- | --------------------------------- | | `src/gc.c` | GC implementation (~1400 lines) | | `include/mruby/gc.h` | `mrb_gc` structure, public GC API | | `include/mruby.h` | Arena save/restore macros | nghttp2-1.70.0/third-party/mruby/doc/internal/PaxHeaders/boxing.md0000644000000000000000000000013215232371065022045 xustar0030 mtime=1785328181.913871842 30 atime=1785328183.361518369 30 ctime=1785328203.908367258 nghttp2-1.70.0/third-party/mruby/doc/internal/boxing.md0000644000175100017510000001226015232371065022436 0ustar00runnerrunner # Boxing The mruby objects and data are represented by C data type `mrb_value`. There are three options how to pack the data values in the `mrb_value`. - Word Boxing - NaN Boxing - No Boxing ## Word Boxing Word boxing packs the Ruby data in a word, which is a natural integer size that equals to the size of pointers (`intptr_t`). Word boxing can be specified by `MRB_WORD_BOXING`, and it's default configuration for most platforms. Some values (called immediate values, e.g. integers, booleans, symbols, etc.) are directly packed in the word. The other data types are represented by pointers to the heap allocated structures. The Word boxing packing bit patterns are like following: | Types | Bit Pattern | | ------ | ------------------------------------- | | object | `xxxxxxxx xxxxxxxx xxxxxxxx xxxxx000` | | fixnum | `xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxx1` | | nil | `00000000 00000000 00000000 00000000` | | true | `00000000 00000000 00000000 00001100` | | false | `00000000 00000000 00000000 00000100` | | undef | `00000000 00000000 00000000 00010100` | | symbol | `xxxxxxxx xxxxxxxx xxxxxxxx xxxxxx10` | ### Inline Float (64-bit) On 64-bit platforms, `double` values are packed into the word using rotation encoding. The IEEE 754 exponent field is rotated so that common exponent values (those not colliding with the pointer/tag patterns above) fit directly in a word. This encoding is lossless for most float values; only a small set of exotic exponents require heap allocation as `RFloat`. To disable inline float and heap-allocate all floats, define `MRB_WORDBOX_NO_INLINE_FLOAT`. ### 32-bit Considerations On 32-bit platforms with 64-bit `double` (the common case), `MRB_WORDBOX_NO_INLINE_FLOAT` is automatically defined because a 64-bit double cannot fit in a 32-bit word. All floats are heap-allocated as `RFloat` objects. The `RFloat` struct uses a `char[]` buffer instead of a `double` field to avoid alignment issues, since GC heap slots (RVALUE) on 32-bit have only 4-byte alignment but `double` requires 8-byte. Accessor functions `mrb_rfloat_value()` and `mrb_rfloat_set()` use `memcpy` for safe access. ## NaN Boxing NaN boxing packs the Ruby data in a floating-point numbers, which represent NaN (Not a Number) values. Under IEEE753 definitions every value that exponent is all set are considered as NaN. That means NaN can represent `2^51` values. NaN boxing is a teaching to pack the values in those NaN representation. In theory, 64-bit pointers are too big to fit in NaN, but practically most OS use only 48 bits at most for pointers (except for some OS e.g. Solaris). The NaN boxing packing bit patterns are like following: | Types | Bit Pattern | | ------ | ------------------------------------------------------------------------- | | float | `SEEEEEEE EEEEFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF` | | +/-inf | `S1111111 11110000 00000000 00000000 00000000 00000000 00000000 00000000` | | nan | `01111111 11111000 00000000 00000000 00000000 00000000 00000000 00000000` | | fixnum | `01111111 11111001 00000000 00000000 IIIIIIII IIIIIIII IIIIIIII IIIIIIII` | | symbol | `01111111 11111110 00000000 00000000 SSSSSSSS SSSSSSSS SSSSSSSS SSSSSSSS` | | misc | `01111111 11111111 00000000 00000000 00000000 00000000 00TTTTTT 0000MMMM` | | object | `01111111 11111100 PPPPPPPP PPPPPPPP PPPPPPPP PPPPPPPP PPPPPPPP PPPPPP00` | | ptr | `01111111 11111100 PPPPPPPP PPPPPPPP PPPPPPPP PPPPPPPP PPPPPPPP PPPPPP01` | | nil | `00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000` | The object values appear far more frequently than floating-point numbers, so we offset the value so that object pointers are unchanged. This technique is called "favor pointer". ## No Boxing No boxing represents `mrb_value` by the C struct with `type` and the value union. This is the most portable (but inefficient) representation. No boxing can be specified by `MRB_NO_BOXING`, and it's default for debugging configuration (e.g. `host-debug`). ## Comparison | Property | Word Boxing | NaN Boxing | No Boxing | | ---------------------- | ----------------- | ---------------- | -------------------- | | `mrb_value` size | 1 word (4/8 byte) | 8 bytes | 2 words (8/16 bytes) | | Default on | most platforms | (manual opt-in) | `host-debug` | | Macro | `MRB_WORD_BOXING` | `MRB_NAN_BOXING` | `MRB_NO_BOXING` | | Inline integers | yes (31/63 bit) | yes (32 bit) | yes (full width) | | Inline floats (64-bit) | yes (rotation) | yes (native) | yes (struct field) | | Inline floats (32-bit) | no (heap RFloat) | yes (native) | yes (struct field) | | Pointer size limit | none | 48 bits | none | | Debugger friendly | no | no | yes | ## ABI Compatibility The boxing mode changes the layout of `mrb_value`. Code compiled with one boxing mode **cannot** be linked against a library built with a different mode. Always use `mruby-config --cflags` to get the correct compiler flags. nghttp2-1.70.0/third-party/mruby/doc/internal/PaxHeaders/architecture.md0000644000000000000000000000013215232371065023241 xustar0030 mtime=1785328181.913511141 30 atime=1785328183.361518369 30 ctime=1785328203.907003149 nghttp2-1.70.0/third-party/mruby/doc/internal/architecture.md0000644000175100017510000001745715232371065023647 0ustar00runnerrunner # mruby Architecture This document provides a map of mruby's internals for developers who want to understand, debug, or contribute to the codebase. ## Overview mruby's execution pipeline: ```text Ruby source → Parser → AST → Code Generator → Bytecode (irep) ↓ VM → Result ``` The design priority is **memory > performance > readability**. ## Object Model All heap-allocated Ruby objects share a common header (`MRB_OBJECT_HEADER`): ```text struct RBasic (8 bytes on 64-bit) ┌──────────────┬─────┬──────────┬────────┬───────┠│ RClass *c │ tt │ gc_color │ frozen │ flags │ │ (class ptr) │ 8b │ 3b │ 1b │ 20b │ └──────────────┴─────┴──────────┴────────┴───────┘ ``` All object structs embed this header via `MRB_OBJECT_HEADER`: | Struct | Ruby Type | Extra Fields | | ------------ | ---------------- | ---------------------------------- | | `RObject` | Object instances | `iv` (instance variables) | | `RClass` | Class/Module | `iv`, `mt` (method table), `super` | | `RString` | String | embedded or heap buffer, length | | `RArray` | Array | embedded or heap buffer, length | | `RHash` | Hash | hash table or k-v array | | `RProc` | Proc/Lambda | `irep` or C function, environment | | `RData` | C data wrapper | `void *data`, `mrb_data_type` | | `RFiber` | Fiber | `mrb_context` | | `RException` | Exception | `iv` | Immediate values (Integer, Symbol, `true`, `false`, `nil`) are encoded directly in `mrb_value` without heap allocation. The encoding depends on the boxing mode (see [boxing.md](boxing.md)). Objects must fit within 5 words (`mrb_static_assert_object_size`). ## Virtual Machine The VM is register-based, using two stacks: a **value stack** for registers (locals, temporaries, arguments) and a **call info stack** for tracking method/block call frames. Each method call pushes a `mrb_callinfo` frame with the method symbol, proc, PC, and argument counts. The dispatch loop in `mrb_vm_run()` decodes opcodes and operates on registers. Method dispatch looks up the receiver's class method table (with a per-state method cache), then either calls a C function directly or pushes a new call frame for Ruby methods. Exception handling uses `setjmp`/`longjmp` (or C++ exceptions if configured). Rescue/ensure handler tables are stored in each irep and searched during stack unwinding. See [vm.md](vm.md) for detailed VM internals, [opcode.md](opcode.md) for the full instruction set. ## Garbage Collector The GC uses **tri-color incremental mark-and-sweep** with an optional **generational mode**. Objects are colored white (unmarked), gray (marked, children pending), black (fully marked), or red (static/ROM). The three-phase cycle (root scan, incremental marking, sweep) runs in small steps between VM instructions to avoid long pauses. Write barriers (`mrb_field_write_barrier`, `mrb_write_barrier`) maintain correctness during incremental marking. The GC arena protects newly created objects in C code. Heap regions (`mrb_gc_add_region`) support embedded systems with fixed memory banks. See [gc.md](gc.md) for detailed GC internals, [../guides/gc-arena-howto.md](../guides/gc-arena-howto.md) for arena usage patterns, [../guides/memory.md](../guides/memory.md) for memory management. ## Compiler Pipeline The compiler transforms Ruby source code through three stages: 1. **Parser** (`parse.y`): Lrama/Bison grammar produces an AST of `mrb_ast_node` structures, tracking lexer state and local scopes. 2. **Code Generator** (`codegen.c`): walks the AST and emits bytecode into `mrb_irep` structures (instruction sequence, literal pool, symbol table, child ireps). 3. **Execution**: the irep is wrapped in an `RProc` and executed by the VM, or serialized to `.mrb` binary format. Alternative loading paths include `mrb_load_string()` (compile and run), `mrb_load_irep()` (load precompiled bytecode), and `mrbc` (ahead-of-time compilation). See [compiler.md](compiler.md) for detailed compiler internals, [opcode.md](opcode.md) for the instruction set. ## Source File Map ### Core (`src/`) | File | Responsibility | | ------------- | ---------------------------------------------- | | `vm.c` | Bytecode dispatch loop, method invocation | | `state.c` | `mrb_state` init/close, irep management | | `gc.c` | Garbage collector (mark-sweep, incremental) | | `class.c` | Class/module definition, method tables | | `object.c` | Core object operations | | `variable.c` | Instance/class/global variables, object shapes | | `proc.c` | Proc/Lambda/closure handling | | `array.c` | Array implementation | | `string.c` | String implementation (embedded, shared, heap) | | `hash.c` | Hash implementation (open addressing) | | `numeric.c` | Integer/Float arithmetic | | `symbol.c` | Symbol table and interning | | `range.c` | Range implementation | | `error.c` | Exception creation, raise, backtrace | | `kernel.c` | Kernel module methods | | `load.c` | `.mrb` bytecode loading | | `dump.c` | Bytecode serialization (write `.mrb`) | | `print.c` | Print/puts/p output | | `backtrace.c` | Stack trace generation | ### Compiler (`mrbgems/mruby-compiler/core/`) | File | Responsibility | | ----------- | ------------------------------- | | `parse.y` | Yacc grammar → AST | | `y.tab.c` | Generated parser (from parse.y) | | `codegen.c` | AST → bytecode (irep) | | `node.h` | AST node type definitions | ### Key Headers (`include/mruby/`) | Header | Contents | | ------------ | ------------------------------------- | | `mruby.h` | `mrb_state`, core API declarations | | `value.h` | `mrb_value`, type enums, value macros | | `object.h` | `RBasic`, `RObject`, object header | | `class.h` | `RClass`, method table types | | `string.h` | `RString`, string macros | | `array.h` | `RArray`, array macros | | `hash.h` | `RHash`, hash API | | `data.h` | `RData`, C data wrapping | | `irep.h` | `mrb_irep`, bytecode structures | | `compile.h` | Compiler context, `mrb_load_string` | | `boxing_*.h` | Value boxing implementations | ## mrbgems System Gems are the module system for mruby.

Gem initialization runs in dependency order via `gem_init.c` (auto-generated). GemBoxes (`mrbgems/*.gembox`) define named collections of gems (e.g., `default.gembox` includes `stdlib`, `stdlib-ext`, `stdlib-io`, `math`, `metaprog`, and binary tools). nghttp2-1.70.0/third-party/mruby/doc/internal/PaxHeaders/vm.md0000644000000000000000000000013215232371065021201 xustar0030 mtime=1785328181.913871842 30 atime=1785328183.361518369 30 ctime=1785328203.904044865 nghttp2-1.70.0/third-party/mruby/doc/internal/vm.md0000644000175100017510000002272615232371065021602 0ustar00runnerrunner # Virtual Machine Internals This document describes mruby's virtual machine for developers working on `src/vm.c` and related code. **Read this if you are:** debugging method dispatch or call frame issues, working on exception handling, implementing new opcodes, modifying fiber/coroutine behavior, or optimizing the dispatch loop. For the instruction set, see [opcode.md](opcode.md). For the compiler that generates bytecode, see [compiler.md](compiler.md). ## Execution Model mruby uses a **register-based VM**. Local variables and temporaries occupy fixed register slots determined at compile time. Each method call gets its own register window on a shared value stack. ## Execution Context The VM state is stored in `mrb_context`: ```text mrb_context +-- stbase..stend value stack (mrb_value[]) +-- cibase..ciend call info stack (mrb_callinfo[]) +-- ci current call frame pointer +-- status fiber state +-- prev previous context (fiber chain) +-- vmexec VM execution state flag ``` The value stack and call info stack grow independently. Each fiber has its own `mrb_context`. ### Stack Sizing - Initial value stack: 128 entries (`STACK_INIT_SIZE`) - Initial call info stack: 32 entries (`CALLINFO_INIT_SIZE`) - Growth factor: 1.5x (or 2x with `MRB_STACK_EXTEND_DOUBLING`) - Minimum growth: 128 entries (`MRB_STACK_GROWTH`) - Max stack depth: `MRB_STACK_MAX` (0x40000 - 128) - Max call depth: `MRB_CALL_LEVEL_MAX` (512, or 128 with ASAN) Exceeding either limit raises `SystemStackError`. When the value stack is reallocated, all `REnv` objects and `mrb_callinfo` stack pointers are adjusted by the delta (`envadjust` function). ## Call Frames Each method or block call pushes a `mrb_callinfo` frame: ```text mrb_callinfo +-- n:4 positional argument count (0-14, 15 = varargs) +-- nk:4 keyword argument count (0-14, 15 = varargs) +-- cci call context info (NONE, DIRECT, SKIP, RESUMED) +-- vis visibility flags (public/private/protected) +-- mid method symbol +-- proc current RProc +-- blk block argument (RProc*) +-- stack pointer into value stack +-- pc program counter (bytecode position) +-- u.env closure environment (REnv*) +-- u.target_class receiver's class ``` ### Stack Layout Per Frame ```text ci->stack: [0] self (receiver) [1..n] positional arguments [n+1..] keyword argument pairs (key, value, key, value, ...) [bidx] block argument [bidx+1..] local variables and temporaries ``` ### Argument Count Encoding The `n` and `nk` fields are 4 bits each (0-15). When `n == 15`, positional arguments are packed into a single Array in register 1. When `nk == 15`, keyword arguments are packed into a single Hash. The block index is calculated by `mrb_bidx(n, nk)`: ```text if n == 15: n = 1 (array) if nk == 15: n += 1 (hash) else: n += nk * 2 (key-value pairs) return n + 1 (skip self) ``` ### Call Context Info (cci) | Value | Name | Meaning | | ----- | --------------- | ------------------------------------- | | 0 | `CINFO_NONE` | Normal VM-to-VM call | | 1 | `CINFO_DIRECT` | Explicit VM call (block, lambda.call) | | 2 | `CINFO_SKIP` | Skip frame in stack traces | | 3 | `CINFO_RESUMED` | Fiber resumed (stop execution) | ## Dispatch Loop The main loop in `mrb_vm_run()` decodes and dispatches opcodes. Two dispatch strategies are available: - **Computed goto** (default on GCC/Clang): a jump table of label addresses (`optable[]`) for direct dispatch. Faster due to better branch prediction. - **Switch-based** (`MRB_USE_VM_SWITCH_DISPATCH`): a standard `switch(insn)` statement. Default on MSVC and other compilers. The dispatch loop is wrapped in `MRB_TRY`/`MRB_CATCH` for exception handling (see [Exception Handling](#exception-handling)). ## Method Dispatch When `OP_SEND` (or `OP_SSEND`, `OP_SUPER`) executes: ### 1. Prepare Arguments Determine argument layout. If argument count < 15, the fast path uses inline registers. Otherwise, arguments are packed into an Array (varargs mode). ### 2. Push Call Frame ```c ci = cipush(mrb, a, CINFO_DIRECT, NULL, NULL, blk, mid, argc); ``` The new frame's stack starts at the previous frame's stack + `a` (the receiver's register index). ### 3. Method Lookup The lookup sequence: 1. **Method cache check**: hash table lookup by `(class, mid)`. Default cache size: `MRB_METHOD_CACHE_SIZE` (256 entries). 2. **Method table walk**: if cache misses, search the receiver's class method table (`mt`), then walk the superclass chain. 3. **Cache store**: on successful lookup, store in the cache. The method cache is invalidated when classes are modified (`mrb_mc_clear_by_class`). ### 4. Invoke - **Ruby method** (irep-based): extend the stack to `irep->nregs`, set `ci->pc` to `irep->iseq`, and jump to the new bytecode. - **C function**: call `func(mrb, recv)` directly, then pop the call frame and store the return value. ### 5. Visibility Check Private methods are only callable without an explicit receiver. Protected methods are callable from the same class hierarchy. Violations raise `NoMethodError`. ## Exception Handling ### setjmp/longjmp By default, mruby uses `setjmp`/`longjmp` for exception control flow: ```c MRB_TRY(&c_jmp) { mrb->jmp = &c_jmp; /* dispatch loop */ } MRB_CATCH(&c_jmp) { /* handle exception */ } MRB_END_EXC(&c_jmp); ``` With `MRB_USE_CXX_EXCEPTION`, C++ `try`/`catch` is used instead. ### Handler Table Each irep contains a catch handler table (appended after iseq in memory) with entries for `rescue` and `ensure` blocks: ```text mrb_irep_catch_handler +-- type RESCUE (0) or ENSURE (1) +-- begin[4] start PC of protected range +-- end[4] end PC of protected range +-- target[4] jump target when handler matches ``` ### Unwinding Process When an exception occurs: 1. Search the current irep's catch handler table (reverse order) for a handler covering the current PC 2. If an `ensure` handler is found: execute it (may re-raise) 3. If a `rescue` handler is found: jump to handler code 4. If no handler: pop the call frame (`cipop`) and repeat with the parent frame 5. `CINFO_DIRECT` frames are destroyed during propagation ## Block and Closure Handling ### REnv (Environment) Closures capture their enclosing scope's variables through `REnv`: ```text REnv +-- stack pointer to captured variable values +-- cxt owning context (NULL if detached from stack) +-- mid method symbol +-- flags length, block index, visibility ``` While the defining scope is active, `REnv::stack` points directly into the VM value stack (shared). This avoids copying. ### Environment Unsharing When a closure outlives its defining scope, `mrb_env_unshare()` copies the captured variables from the stack to a heap-allocated buffer: ```c mrb_env_unshare(mrb, env, noraise); ``` After unsharing, `MRB_ENV_CLOSE(env)` sets `cxt = NULL` to indicate the environment is detached. A write barrier is issued for GC correctness. ### Proc Types | Flag | Meaning | | ------------------- | ------------------------------ | | `MRB_PROC_CFUNC_FL` | C function (not irep-based) | | `MRB_PROC_STRICT` | Lambda (strict argument check) | | `MRB_PROC_ORPHAN` | No environment attachment | | `MRB_PROC_ENVSET` | Has captured environment | | `MRB_PROC_SCOPE` | Defines a new variable scope | ## Fiber Switching Fibers are lightweight coroutines. Each fiber has its own `mrb_context` with separate value and call info stacks. ### Fiber States ```text CREATED --> RUNNING --> SUSPENDED --> TERMINATED | ^ +-----------+ (yield/resume) TRANSFERRED (via Fiber#transfer) ``` ### Context Switch On `Fiber#resume`: 1. Save current context state 2. Set `mrb->c` to the fiber's context 3. Push arguments onto the fiber's stack 4. Continue execution in the fiber On `Fiber.yield`: 1. Save fiber context 2. Restore the parent context (`mrb->c = c->prev`) 3. Return yield values to the parent ### Fiber Termination When a fiber completes (`fiber_terminate`): 1. Unshare any environments that reference the fiber's stack 2. Set status to `TERMINATED` 3. Free the fiber's stacks 4. Switch to the previous context ### C Function Boundary Fibers cannot yield across C function boundaries. You cannot call `Fiber.yield` from within a C-implemented method (except via `mrb_fiber_yield` at return). This is because C call frames cannot be suspended and resumed. ## GC Integration The VM saves the arena index at the start of the dispatch loop: ```c int ai = mrb_gc_arena_save(mrb); ``` After each C function call, the arena is shrunk back: ```c mrb_gc_arena_shrink(mrb, ai); ``` This prevents temporary objects created by C functions from accumulating in the arena. Write barriers are issued when environments are detached or closed, ensuring the incremental GC correctly tracks live references. ## Source Files | File | Contents | | ----------------------- | ---------------------------------------------- | | `src/vm.c` | Dispatch loop, method invocation (~1900 lines) | | `include/mruby.h` | `mrb_state`, `mrb_callinfo`, `mrb_context` | | `include/mruby/proc.h` | `RProc`, `REnv` structures | | `include/mruby/throw.h` | `MRB_TRY`/`MRB_CATCH` macros | nghttp2-1.70.0/third-party/mruby/doc/internal/PaxHeaders/compiler.md0000644000000000000000000000013215232371065022371 xustar0030 mtime=1785328181.913871842 30 atime=1785328183.361518369 30 ctime=1785328203.909730275 nghttp2-1.70.0/third-party/mruby/doc/internal/compiler.md0000644000175100017510000002572615232371065022775 0ustar00runnerrunner # Compiler Pipeline Internals This document describes mruby's compilation pipeline for developers working on the parser, code generator, or bytecode format. **Read this if you are:** adding new syntax or modifying the parser, debugging codegen issues (wrong registers, missing opcodes), working with the `.mrb` binary format, or understanding how Ruby constructs map to bytecode. ## Pipeline Overview ```text Ruby source | v Lexer/Parser (parse.y) | v AST (mrb_ast_node) | v Code Generator (codegen.c) | v Bytecode (mrb_irep) | v VM execution -or- .mrb binary file ``` ## Stage 1: Lexer and Parser The lexer and parser are combined in a single Lrama/Bison grammar file: `mrbgems/mruby-compiler/core/parse.y`. ### Parser State The parser maintains extensive state in `mrb_parser_state`: - **lstate**: current lexer state (EXPR_BEG, EXPR_END, EXPR_ARG, EXPR_DOT, EXPR_FNAME, etc.). Controls how tokens like `+`/`-` are interpreted (sign vs operator) and whether newlines are significant. - **locals**: stack of local variable lists (one per scope), stored as cons-lists of symbols. - **lex_strterm**: string/heredoc parsing state for handling nested interpolation. - **cond_stack**, **cmdarg_stack**: bit stacks tracking conditional and command argument contexts. - **tree**: root AST node after successful parse. - **error_buffer**: accumulated parse errors. ### AST Nodes The parser produces an AST using two node types: - **Cons-list nodes**: traditional binary tree pairs (car/cdr) - **Variable-sized nodes**: have a header with `node_type`, `lineno`, and `filename_index` Key node types include `NODE_SCOPE` (new variable scope), `NODE_STMTS` (statement sequence), `NODE_IF`, `NODE_WHILE`, `NODE_CALL` (method call), `NODE_DEF` (method definition), `NODE_CLASS`, `NODE_RESCUE`, `NODE_ENSURE`, etc. See `mrbgems/mruby-compiler/core/node.h` for the complete list. ### Local Variable Tracking Local variables are tracked per-scope during parsing: - `local_add(sym)`: register a new local variable in current scope - `local_var_p(sym)`: check if a symbol is a local variable (affects whether an identifier is parsed as a method call or variable reference) ## Stage 2: Code Generator The code generator (`mrbgems/mruby-compiler/core/codegen.c`) walks the AST and emits bytecode into `mrb_irep` structures. ### Codegen Scope Each lexical scope (method, block, class body) has its own `codegen_scope`: ```text codegen_scope +-- sp current register index (stack pointer) +-- pc current instruction count +-- nlocals number of local variables +-- nregs maximum register index used +-- lv local variable list +-- iseq[] instruction sequence (grows dynamically) +-- pool[] literal pool (strings, numbers) +-- syms[] symbol table (method/variable names) +-- reps[] child ireps (nested methods/blocks) +-- catch_table[] exception handler entries +-- loop current loop context stack +-- prev parent scope +-- mscope true if method/module/class scope ``` Scopes nest for blocks, method definitions, and class/module bodies. Each scope produces one `mrb_irep`. ### Register Allocation The code generator uses a simple stack-based register allocator: - Register 0 is always `self` - Registers 1..nlocals-1 are local variables (in declaration order) - Registers nlocals..nregs-1 are temporaries `push()` increments `sp` and tracks the high-water mark in `nregs`. `pop()` decrements `sp`. The allocator is linear - it does not reuse temporaries within an expression. ### Instruction Emission Instructions are emitted via helper functions: - `genop_0(opcode)`: no operands - `genop_1(opcode, a)`: one operand (auto-extends with OP_EXT1 if a > 255) - `genop_2(opcode, a, b)`: two operands (auto-extends with OP_EXT1/2/3 as needed) - `genop_3(opcode, a, b, c)`: three operands - `genop_W(opcode, a)`: 24-bit operand - `genop_2S(opcode, a, b)`: one 8-bit + one 16-bit operand ### Peephole Optimization The code generator performs limited peephole optimizations, such as removing redundant `OP_MOVE` instructions and combining consecutive literal loads. Optimization is disabled at jump targets and when `no_optimize` is set in the compilation context. ### Loop Context Loop constructs (`while`, `until`, `for`, blocks) push a `loopinfo` structure that tracks jump destinations: - `pc0`: destination for `next` - `pc1`: destination for `redo` - `pc2`: destination for `break` Loop types (`LOOP_NORMAL`, `LOOP_BLOCK`, `LOOP_FOR`, `LOOP_BEGIN`, `LOOP_RESCUE`) determine how `break`/`next`/`redo` behave. ## IRep Structure The compiled bytecode is stored in `mrb_irep` (Instruction REPresentation): ```text mrb_irep +-- iseq[] instruction sequence (mrb_code array) +-- pool[] literal pool (mrb_irep_pool entries) +-- syms[] symbol table (mrb_sym array) +-- reps[] child ireps (nested scopes) +-- lv[] local variable names (for debugging) +-- nlocals local variable count +-- nregs register count (locals + temporaries) +-- ilen instruction count +-- plen pool entry count +-- slen symbol count +-- rlen child irep count +-- clen catch handler count +-- debug_info source file/line mapping ``` ### Literal Pool Pool entries store constants referenced by instructions: | Type | Tag | Description | | ---------------- | --- | ------------------------------- | | `IREP_TT_STR` | 0 | Dynamic string (heap allocated) | | `IREP_TT_SSTR` | 2 | Static string (read-only) | | `IREP_TT_INT32` | 1 | 32-bit integer | | `IREP_TT_INT64` | 3 | 64-bit integer | | `IREP_TT_FLOAT` | 5 | Floating-point number | | `IREP_TT_BIGINT` | 7 | Arbitrary-precision integer | The code generator deduplicates pool entries: identical strings and equal numeric values share the same pool index. ### Catch Handler Table Exception handler entries are appended after the instruction sequence in memory: ```text mrb_irep_catch_handler +-- type MRB_CATCH_RESCUE (0) or MRB_CATCH_ENSURE (1) +-- begin[4] start PC of protected range +-- end[4] end PC of protected range +-- target[4] jump target when handler fires ``` During exception unwinding, handlers are searched in reverse order (last to first) for the current PC. ## Operand Encoding Standard instructions use 8-bit operands. When a value exceeds 255, extension prefixes widen operands to 16 bits: | Prefix | Effect | | --------- | --------------------------------- | | `OP_EXT1` | First operand (a) becomes 16-bit | | `OP_EXT2` | Second operand (b) becomes 16-bit | | `OP_EXT3` | Both a and b become 16-bit | Instruction formats: | Format | Layout | Size | | ------ | ----------------------------- | ------- | | Z | opcode only | 1 byte | | B | opcode + a(8) | 2 bytes | | BB | opcode + a(8) + b(8) | 3 bytes | | BBB | opcode + a(8) + b(8) + c(8) | 4 bytes | | BS | opcode + a(8) + b(16) | 4 bytes | | BSS | opcode + a(8) + b(16) + c(16) | 6 bytes | | S | opcode + a(16) | 3 bytes | | W | opcode + a(24) | 4 bytes | See [opcode.md](opcode.md) for the full instruction table. ## OP_ENTER: Argument Specification `OP_ENTER` encodes a method's argument layout in a 24-bit value (W format). The bit fields are defined by the `MRB_ARGS_*` macros: ```text Bits 23 no-block flag Bits 18-22 required argument count (5 bits, 0-31) Bits 13-17 optional argument count (5 bits, 0-31) Bit 12 rest argument flag (*args) Bits 7-11 post-rest argument count (5 bits, 0-31) Bits 2-6 keyword argument count (5 bits, 0-31) Bit 1 keyword rest flag (**kwargs) Bit 0 block argument flag (&block) ``` Example: `def foo(a, b=1, *rest, &block)` produces an aspec with 1 required, 1 optional, rest flag set, and block flag set. ## Presym: Compile-Time Symbols The presym system pre-allocates symbol IDs at build time for frequently used method names and operators. This avoids runtime string interning for common symbols. Generated by `lib/mruby/presym.rb`, the presym table maps symbol names to compile-time constants: | Macro | Example | Symbol | | ----------------- | --------------------- | ------------- | | `MRB_SYM(name)` | `MRB_SYM(initialize)` | `:initialize` | | `MRB_SYM_B(name)` | `MRB_SYM_B(map)` | `:map!` | | `MRB_SYM_Q(name)` | `MRB_SYM_Q(nil)` | `:nil?` | | `MRB_SYM_E(name)` | `MRB_SYM_E(name)` | `:name=` | | `MRB_OPSYM(op)` | `MRB_OPSYM(add)` | `:+` | | `MRB_IVSYM(name)` | `MRB_IVSYM(name)` | `:@name` | | `MRB_CVSYM(name)` | `MRB_CVSYM(count)` | `:@@count` | | `MRB_GVSYM(name)` | `MRB_GVSYM(stdout)` | `:$stdout` | ## Binary Format (.mrb) Precompiled bytecode is stored in the RITE binary format: ```text Header: "RITE" magic + version ("0400") + CRC + size Section IREP: instruction sequences, pools, symbols Section DBG: debug info (optional, filename/line mapping) Section LVAR: local variable names (optional) Footer: "END\0" ``` Loading functions: - `mrb_load_irep(mrb, bin)`: load and execute from byte array - `mrb_load_irep_buf(mrb, buf, len)`: load with explicit size (safer) - `mrb_read_irep(mrb, bin)`: load without executing (returns `mrb_irep*`) - `mrb_load_irep_file(mrb, fp)`: load from file The `mrbc` command-line tool performs ahead-of-time compilation: ```shell mrbc -o output.mrb source.rb # binary format mrbc -Boutput source.rb # C array format ``` ## Compilation Limits | Limit | Value | | ---------------------- | ----------------------------- | | Max nesting depth | 256 (`MRB_CODEGEN_LEVEL_MAX`) | | Max local variables | 255 (uint16 `nlocals`) | | Max symbols per irep | 65535 | | Max operand (standard) | 255 (8-bit) | | Max operand (extended) | 65535 (16-bit) | ## Source Files | File | Contents | | --------------------------------------- | ------------------------- | | `mrbgems/mruby-compiler/core/parse.y` | Lrama/Bison grammar | | `mrbgems/mruby-compiler/core/y.tab.c` | Generated parser | | `mrbgems/mruby-compiler/core/codegen.c` | Code generator | | `mrbgems/mruby-compiler/core/node.h` | AST node types | | `include/mruby/irep.h` | IRep structure definition | | `include/mruby/compile.h` | Compiler context API | | `include/mruby/ops.h` | Opcode definitions | | `src/load.c` | Binary format loader | | `src/dump.c` | Binary format writer | | `lib/mruby/presym.rb` | Presym table generator | nghttp2-1.70.0/third-party/mruby/doc/PaxHeaders/mruby_logo_red_icon.png0000644000000000000000000000013215232371065023147 xustar0030 mtime=1785328181.914511146 30 atime=1785328183.362518374 30 ctime=1785328203.897012423 nghttp2-1.70.0/third-party/mruby/doc/mruby_logo_red_icon.png0000644000175100017510000001233315232371065023541 0ustar00runnerrunner‰PNG  IHDRddpâ•T pHYs  šœsRGBÙÉ,€IDATxÚí] xŒwŸ&TP"â¨vId›¢DDZm¥‡«EiQê¨Rª¶î–§ÛC—’Ö.=ô «µ[Ôö¢u&H!B$$G9äÄ‘Cîx÷ç}¿trÍdf>sÐyŸç÷„ÉÌ—ï{ÿ÷ü£±‹]ìb»ØÅ.v±‹] —]5]€qÀÛÀó€g@+`0xðíš»¹$4IðÒоŽ€'p¿†ö?€×º2®UÃEåóNvmª'ãµޢؽ÷jhW# ù7ÓP ;ˆèB:(¯7ýUCÁÝäýÁ¾øÝ_4´»5þ×p¼înת¢¸ÇÉÀÖàî¢ü âðã-èÜ’itqÛzÊ=q˜òÏœ üغr$Ò~üŠbç‡å8ÒΆlAŒ˜yÃ)üùäï¬!…Øãv-ëV¾;0XüD%€Œp±çå¾ÿ˜ ‘’+Ù»` ù»ÀbšÞ d¿5u8ílŒkúðµ—þ”{'Ðx xè¸)¿s¼€eÀ6 Q/1 ÐC\ËN'ül%Š òtåð2V¿X,¤À².·ä¿¡¸´·# M€iÀ.

These two objectives are partially contradicting. Ruby is an expressive language with complex implementation details which are difficult to implement in a lightweight manner. To cope with this, limitations to the "Ruby Compatibility" are defined. This document is collecting these limitations. ## Integrity This document does not contain a complete list of limitations. Please help to improve it by submitting your findings. ## `Kernel.raise` in rescue clause `Kernel.raise` without arguments does not raise the current exception within a rescue clause. ```ruby begin 1 / 0 rescue raise end ``` #### CRuby `ZeroDivisionError` is raised. #### mruby `RuntimeError` is raised instead of `ZeroDivisionError`. To re-raise the exception, you have to do: ```ruby begin 1 / 0 rescue => e raise e end ``` ## Fiber execution can't cross C function boundary mruby's `Fiber` is implemented similarly to Lua's co-routine. This results in the consequence that you can't switch context within C functions. Only exception is `mrb_fiber_yield` at return. ## `Array` does not support instance variables To reduce memory consumption `Array` does not support instance variables. ```ruby class Liste < Array def initialize(str = nil) @field = str end end p Liste.new "foobar" ``` #### CRuby `[]` #### mruby `ArgumentError` is raised. ## `defined?` The `defined?` keyword is considered too complex to be fully implemented. It is recommended to use `const_defined?` and other reflection methods instead. ```ruby defined?(Foo) ``` #### CRuby ``` nil ``` #### mruby `NameError` is raised. ## `alias` on global variables Aliasing a global variable works in CRuby but is not part of the ISO standard. ```ruby alias $a $__a__ ``` #### CRuby `nil` #### mruby Syntax error ## Operator modification Operators on some of the primitive classes cannot be overridden, as they are optimized in the VM. ```ruby class String def + end end 'a' + 'b' ``` #### CRuby `ArgumentError` is raised. The re-defined `+` operator does not accept any arguments. #### mruby `'ab'` Behavior of the operator wasn't changed. ## `Kernel#binding` is not supported without mruby-binding gem `Kernel#binding` method requires the `mruby-binding` gem (included in the `metaprog` gembox). Without this gem, `binding` is not available. ## `nil?` redefinition in conditional expressions Redefinition of `nil?` is ignored in conditional expressions. ```ruby a = "a" def a.nil? true end puts(a.nil? ? "truthy" : "falsy") ``` Ruby outputs `truthy`. mruby outputs `falsy`. ## Argument Destructuring ```ruby def m(a,(b,c),d); p [a,b,c,d]; end m(1,[2,3],4) # => [1,2,3,4] ``` Destructured arguments (`b` and `c` in above example) cannot be accessed from the default expression of optional arguments and keyword arguments, since actual assignment is done after the evaluation of those default expressions. Thus: ```ruby def f(a,(b,c),d=b) p [a,b,c,d] end f(1,[2,3]) ``` CRuby gives `[1,2,3,nil]`. mruby raises `NoMethodError` for `b`. Keyword argument expansion has similar restrictions. The following example, gives `[1, 1]` for CRuby, mruby raises `NoMethodError` for `b`. ```ruby def g(a: 1, b: a) p [a,b] end g(a:1) ``` ## No Double Dispatch in Module Loading To make implementation simpler, mruby does not use double dispatching in module loading (`include`/`prepend`/`extend`). Those method internally called corresponding actual load methods (`append_features`/`prepend_features`/`extend_object`). But they are rarely overloaded, consumes more memory, and make loading little bit slower. As a Ruby implementation for the smaller device, we decided mruby simpler. ```ruby module M def self.append_features(mod) p :append end end class C include M end ``` #### CRuby Prints `:append`. #### mruby Nothing printed (since `include` does not call `append_features` internally). ## No `#hash` call for small hashes For performance reasons, mruby avoids calling the `#hash` method on keys when a hash table is small. This means that custom `#hash` methods on key objects may not be executed. ## Pattern Matching Pattern matching is only partially supported in mruby. Currently, only the rightward assignment operator (`=>`) with simple variable binding is implemented. ```ruby expr => var # Supported: assigns expr to var ``` #### CRuby Full pattern matching with `case/in` syntax and various pattern types: ```ruby case [1, 2, 3] in [a, b, c] puts "#{a}, #{b}, #{c}" # => "1, 2, 3" end case {name: "Alice", age: 30} in {name:, age:} puts "#{name} is #{age}" # => "Alice is 30" end ``` #### mruby Only rightward assignment with simple variable binding: ```ruby [1, 2, 3] => x puts x # => [1, 2, 3] ``` The following are **not supported**: - `case/in` syntax - Array patterns: `in [a, b, c]` - Hash patterns: `in {name:, age:}` - Guard clauses: `in pattern if condition` - Pin operator: `in ^variable` - Find patterns: `in [*, x, *]` - Alternative patterns: `in pattern1 | pattern2` - Boolean pattern check: `value in pattern` Note: mruby does provide `Array#deconstruct` and `Hash#deconstruct_keys` methods for future pattern matching compatibility. ## No Refinements Module refinements (`refine`, `using`) are not supported in mruby. ## No `Encoding` Class mruby does not have an `Encoding` class. Strings are treated as byte sequences by default. UTF-8 aware string operations can be enabled with the `MRB_UTF8_STRING` compile flag. ## Integer Precision Varies by Boxing Mode Integer size depends on the value boxing configuration: | Configuration | Integer range | | ----------------------------- | ---------------- | | Word boxing, 64-bit (default) | roughly +/- 2^62 | | Word boxing, 32-bit (default) | roughly +/- 2^30 | | NaN boxing (64-bit only) | -2^31 to 2^31-1 | Code relying on 64-bit integer precision may behave differently across configurations. The `mruby-bigint` gem provides arbitrary-precision integers when included. ## No `ObjectSpace.each_object` by Default `ObjectSpace` is only available via the `mruby-objectspace` gem (included in the `stdlib` gembox). Even with the gem, `ObjectSpace.each_object` has limited functionality compared to CRuby. nghttp2-1.70.0/third-party/mruby/doc/PaxHeaders/mruby3.2.md0000644000000000000000000000013215232371065020324 xustar0030 mtime=1785328181.913871842 30 atime=1785328183.362518374 30 ctime=1785328203.913846757 nghttp2-1.70.0/third-party/mruby/doc/mruby3.2.md0000644000175100017510000000632215232371065020717 0ustar00runnerrunner# User visible changes in `mruby3.2` from `mruby3.1` # The language - Now `a::B = c` should evaluate `a` then `c`. - Anonymous arguments `*`, `**`, `&` can be passed for forwarding. - Multi-precision integer is available now via `mruby-bigint` gem. # mruby VM and bytecode - `OP_ARYDUP` was renamed to `OP_ARYSPLAT`.

This change also affects API functions such as `mrb_load_string()` and `mrb_load_file()`. The conditions under which the previous top-level local variables referenced from blocks is detached in these functions are as follows: - If the function has no `mrbc_context` pointer parameter, or the `mrbc_context` pointer parameter is set to `NULL`. - If the number of variables held in the `mrbc_context` pointer is less than the number of previous top-level local variables.

[#5246](https://github.com/mruby/mruby/pull/5246) - Hash value omission [Ruby:Feature#14579](https://bugs.ruby-lang.org/issues/14579) ## Configuration Options Changed Some configuration macros are available: - `MRB_WORDBOX_NO_INLINE_FLOAT` (formerly `MRB_WORDBOX_NO_FLOAT_TRUNCATE`): by default, float values are packed in the word if possible, but define this macro to allocate float values in the heap. - `MRB_USE_RO_DATA_P_ETEXT`: define this macro if `_etext` is available on your platform. - `MRB_NO_DEFAULT_RO_DATA_P`: define this macro to avoid using predefined `mrb_ro_data_p()` function --- # Updated Features ## New build configurations We have added several new build configurations in the `build_config` directory. - `cross-mingw-winetest.rb` - `cross-mingw.rb` - `nintendo_switch.rb` - `serenity.rb` - `minimal`: minimal configuration - `host-f32`: compiles with `mrb_float` as 32-bit `float` - `host-nofloat`: compiles with no float configuration - `android_arm64_v8a.rb`: renamed from `android_arm64-v8a.rb` ## Core Libraries ### New Methods - `Array#product` - `Array#repeated_combination` - `Array#repeated_permutation` - `Kernel#__ENCODING__` - `Random.bytes` - `Random#bytes` - `String#center` ### New Gem Enhancement - `mrbgems/mruby-pack` now supports `M` directive (Q encoding) - `mrbgems/mruby-pack` now supports `X` directive (back-up by bytes) - `mrbgems/mruby-pack` now supports `@` directive (absolute position) - `mrbgems/mruby-pack` now supports `w` directive (BER compression) ## Tools - `mruby-config` now supports `--cc` and `--ld` options. - Remove `OP_` prefix from `mruby -v` code dump output. - Prohibit use of `OP_EXT{1,2,3}` by `mrbc` with `--no-ext-ops` option. ## Features for mruby Developer - Add new specifier `c` to `mrb_get_args()` for receive Class/Module. --- # Breaking Changes ## Incompatibly Changed Methods - `Kernel#printf` (`mruby-sprintf`) Format specifiers `%a` and `%A` are removed. - `Kernel#puts` (`mruby-print`) Now expand Array arguments. ## mruby VM and bytecode Due to improvements in the binary format, mruby binaries are no longer backward compatible. To run the mruby binaries on mruby 3.1, recompile with the mruby 3.1 `mrbc`. - Upgrade mruby VM version `RITE_VM_VER` to `0300` (means mruby 3.0 or after). - Upgrade mruby binary version `RITE_BINARY_FORMAT_VER` to `0300`. ## Reintroduced Instructions `mruby3.0` removed `OP_EXT1`, `OP_EXT2`, `OP_EXT3` for operand extension. But the operand size limitations was too tight for real-world application. `mruby3.1` reintroduces those extension instructions. ## Removed Instructions `mruby3.1` removed following instructions. - `OP_LOADL16` - `OP_LOADSYM16` - `OP_STRING16` - `OP_LAMBDA16` - `OP_BLOCK16` - `OP_METHOD16` - `OP_EXEC16` Those instructions are no longer needed by reintroduction of extension instructions. - `OP_SENDV` - `OP_SENDVB` Those instructions for method calls with variable number of arguments are no longer needed. They are covered by `OP_SEND` instruction with `n=15`. ## New Instructions `mruby3.1` introduces following new instructions. - `OP_GETIDX`: takes 1 operands `R[a][a+1]` - `OP_SETIDX`: takes 1 operands `R[a][a+1]=R[a+2]` - `OP_SSEND`: takes 3 operands `a=self.b(c...)`; see `OP_SEND` - `OP_SSENDB`: takes 3 operands `a=self.b(c...){...}`; see `OP_SEND` - `OP_SYMBOL`: takes 2 operands `R[a] = intern(Pool[b])` ### `OP_GETIDX` and `OP_SETIDX` Execute `obj[int]` and `obj[int] = value` respectively, where `obj` is `string|array|hash`. ### `OP_SSEND` and `OP_SSENDB` They are similar to `OP_SEND` and `OP_SENDB` respectively. They initialize the `R[a]` by `self` first so that we can skip one `OP_LOADSELF` instruction for each call. ### `OP_SYMBOL` Extracts the character string placed in the pool as a symbol. ## Changed Instructions ### `OP_SEND` and `OP_SENDB` Method calling instructions are unified. Now `OP_SEND` and `OP_SENDB` (method call with a block) can support both splat arguments and keyword arguments as well. The brief description of the instructions: |`OP_SEND` | BBB | `R[a] = R[a].call(Syms[b],R[a+1..n],R[a+n+1],R[a+n+2]..nk) c=n|nk<<4` | |`OP_SENDB` | BBB | `R[a] = R[a].call(Syms[b],R[a+1..n],R[a+n+1..nk],R[a+n+2..nk],&R[a+n+2*nk+2]) c=n|nk<<4` | Operand C specifies the number of arguments. Lower 4 bits (`n`) represents the number of ordinal arguments, and higher 4 bits (`nk`) represents the number of keyword arguments. When `n == 15`, the method takes arguments packed in an array. When `nk == 15`, the method takes keyword arguments are packed in a hash. ### `OP_ARYPUSH` Now takes 2 operands and pushes multiple entries to an array. ## Boxing Updated ### Word Boxing `MRB_WORD_BOXING` now packs floating-point numbers in the word, if the size of `mrb_float` is equal or smaller than the size of `mrb_int` by default. If the size of `mrb_float` and `mrb_int` are same, the last 2 bits in the `mrb_float` are trimmed and used as flags. If you need full precision, you need to define `MRB_WORDBOX_NO_INLINE_FLOAT` (formerly `MRB_WORDBOX_NO_FLOAT_TRUNCATE`) as described above. ### NaN Boxing Previous NaN boxing packs values in NaN representation, but pointer retrievals are far more frequent than floating-point number references. So we add constant offset to NaN representation to clear higher bits of pointer representation. This representation is called "Favor Pointer" NaN Boxing. Also, previous NaN boxing limit the size of `mrb_int` to 4 bytes (32 bits) to fit in NaN values. Now we allocate integer values in the heap, if the value does not fit in the 32 bit range, just like we did in Word Boxing. ## Constant Folding The code generator was updated to reduce the number of instructions, e.g. ``` a = 2 * 5 ``` will be interpreted as ``` a = 10 ``` In addition, we have improved peephole optimizations, for example: ``` GETIV R4 :@foo MOVE R1 R4 ``` to ``` GETIV R1 :@foo ``` ## `String#hash` now use `FNV1a` algorithm For better and faster hash values. --- # Major bugfixes - Fix infinite recursive call bugs in integer division [98799aa6](https://github.com/mruby/mruby/commit/98799aa6) - Fix to raise TypeError with super inside instance_eval / class_eval [#5476](https://github.com/mruby/mruby/pull/5476) - Fix to call `method_added` hooks on method definitions; [#2339](https://github.com/mruby/mruby/pull/2339) - Fix a potential buffer overflow in `time_zonename` [26340a88](https://github.com/mruby/mruby/commit/26340a88) - Fix `Module.instance_eval` bug [#5528](https://github.com/mruby/mruby/pull/5528) - Fix fix `M` packing bug [bfe2bd49](https://github.com/mruby/mruby/commit/bfe2bd49) - Fix a bug regarding attribute assignment with kargs [de2b4bd0](https://github.com/mruby/mruby/commit/de2b4bd0) - Fix SIGSEGV with mrbgems/mruby-method [#5580](https://github.com/mruby/mruby/pull/5580) - Fix print error before cleanup in `codegen_error()` [#5603](https://github.com/mruby/mruby/pull/5603) - Fix a bug in unpacking BER [#5611](https://github.com/mruby/mruby/pull/5611) - Fix a bug with numbered parameters as arguments [#5605](https://github.com/mruby/mruby/pull/5605) - Fix `mrb_ary_shift_m` initialization bug [27d1e013](https://github.com/mruby/mruby/commit/27d1e013) - Fix keyword argument with `super` [#5628](https://github.com/mruby/mruby/pull/5628) - Fix a bug with numbered parameters on toplevel [7e7f1b2f](https://github.com/mruby/mruby/commit/7e7f1b2f) - Fix keyword argument bug [#5632](https://github.com/mruby/mruby/issues/5632) - Fix multiple assignments in parameters [#5647](https://github.com/mruby/mruby/issues/5647) - Fix keyword parameters not passing through super [#5660](https://github.com/mruby/mruby/issues/5660) - Fix infinite loop from unclosed here-doc [#5676](https://github.com/mruby/mruby/issues/5676) - Fix negative integer division bug [#5678](https://github.com/mruby/mruby/issues/5678) # CVEs ## Fixed CVEs Following CVEs are fixed in this release. - [CVE-2021-4110](https://www.cve.org/CVERecord?id=CVE-2021-4110) - [CVE-2021-4188](https://www.cve.org/CVERecord?id=CVE-2021-4188) - [CVE-2022-0080](https://www.cve.org/CVERecord?id=CVE-2022-0080) - [CVE-2022-0240](https://www.cve.org/CVERecord?id=CVE-2022-0240) - [CVE-2022-0326](https://www.cve.org/CVERecord?id=CVE-2022-0326) - [CVE-2022-0481](https://www.cve.org/CVERecord?id=CVE-2022-0481) - [CVE-2022-0631](https://www.cve.org/CVERecord?id=CVE-2022-0631) - [CVE-2022-0632](https://www.cve.org/CVERecord?id=CVE-2022-0632) - [CVE-2022-0890](https://www.cve.org/CVERecord?id=CVE-2022-0890) - [CVE-2022-1071](https://www.cve.org/CVERecord?id=CVE-2022-1071) - [CVE-2022-1106](https://www.cve.org/CVERecord?id=CVE-2022-1106) - [CVE-2022-1201](https://www.cve.org/CVERecord?id=CVE-2022-1201) - [CVE-2022-1427](https://www.cve.org/CVERecord?id=CVE-2022-1427) ## Unaffected CVEs Following CVEs do not cause problems in this release.

By tradition, the gem name start with `mruby-bin-`, e.g. `mruby-bin-debugger`. ### `mrbgem.rake` file The executable name is specified in `mrbgem.rake` file at the top of your `mrbgem` directory. ```ruby MRuby::Gem::Specification.new('mruby-bin-example') do |spec| spec.license = 'MIT' spec.author = 'mruby developers' spec.summary = 'Example for executable command gem' spec.bins = %w(mruby-example) # <- this is binary name end ``` ### Source tree structure The source file for the gem executable should be in `/tools/`. Currently, we support C or C++ source code (`.c`, `.cpp`, `.cxx`, `.cc`) for the executable. Ruby source files are not supported. Put the functionality in the different gem and specify dependency to it in `mrbgem.rake`. ## Normal compilation process The `libmruby` is a normal library so that you can just link it to your application. Specify proper compiler options (`-I` etc.) and linker options (`-lmruby` etc.) to compile and link your application. Specify those options in your build script (e.g. `Makefile`). ### Compiler options You need to specify compiler options that are compatible to mruby configuration, for example: - `-I` to specify the place for mruby header files - `-D` to specify mruby configuration macros To retrieve compiler options used to build `mruby`, you can use `mruby-config` command with following options: - `--cc` compiler name - `--cflags` options passed to compiler ```console $ mruby-config --cflags -std=gnu99 -g -O3 -Wall -DMRB_GC_FIXED_ARENA -I/home/matz/work/mruby/include -I/home/matz/work/mruby/build/host/include ``` ### Linker options Just like compiler options, you need to specify linker options that are compatible to mruby configuration. To retrieve linker options, you can use `mruby-config` with following options: - `--ld` linker name - `--ldflags` options passed to linker - `--ldflags-before-libs` options passed to linker before linked libraries - `--libs` linked libraries ```console $ mruby-config --ldflags -L/home/matz/work/mruby/build/host/lib $ mruby-config --ldflags-before-libs # $ mruby-config --libs -lmruby -lm ``` nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/amalgamation.md0000644000000000000000000000013215232371065022655 xustar0030 mtime=1785328181.912364645 30 atime=1785328183.359518359 30 ctime=1785328203.919462752 nghttp2-1.70.0/third-party/mruby/doc/guides/amalgamation.md0000644000175100017510000000774615232371065023263 0ustar00runnerrunner # Amalgamation Amalgamation combines all mruby source files into a single `mruby.c` and `mruby.h` for easy embedding, similar to SQLite's distribution model. ## Benefits - **Simple integration**: Just two files to add to your project - **Single compilation unit**: Enables better compiler optimization - **No build system required**: Compile directly with any C compiler - **Portable**: No external dependencies beyond standard C library (but see [Platform-Dependent Gems](#platform-dependent-gems) below) ## Generating Amalgamation ```console rake amalgam ``` Output files are generated in `build//amalgam/`: - `mruby.h` - All headers concatenated in dependency order - `mruby.c` - All sources concatenated (core + gems + mrblib) ### With Custom Configuration The amalgamation includes gems specified in your build configuration: ```console MRUBY_CONFIG=build_config/minimal.rb rake amalgam ``` ## Using the Amalgamation ### Basic Usage ```c #include "mruby.h" int main(void) { mrb_state *mrb = mrb_open(); mrb_load_string(mrb, "puts 'Hello from mruby!'"); mrb_close(mrb); return 0; } ``` ### Compiling ```console gcc -I./build/host/amalgam your_app.c ./build/host/amalgam/mruby.c -o your_app -lm ``` For optimized builds: ```console gcc -O2 -DNDEBUG -I./build/host/amalgam your_app.c ./build/host/amalgam/mruby.c -o your_app -lm ``` ## Gem Compatibility ### Known Working Gems The following gems work with amalgamation: - `mruby-compiler` - Required for `mrb_load_string` - `mruby-eval` - `eval`, `Binding` - `mruby-array-ext`, `mruby-string-ext`, `mruby-hash-ext` - `mruby-numeric-ext`, `mruby-range-ext`, `mruby-symbol-ext` - `mruby-proc-ext`, `mruby-kernel-ext`, `mruby-object-ext`, `mruby-class-ext` - `mruby-enum-ext`, `mruby-compar-ext` - `mruby-error`, `mruby-math`, `mruby-struct` - `mruby-bigint`, `mruby-rational`, `mruby-complex` - `mruby-io` (with `hal-posix-io`) - `mruby-task` (with `hal-posix-task`) ### Platform-Dependent Gems Gems that use a HAL (Hardware Abstraction Layer) include platform-specific code in the amalgamation. For example, if `mruby-io` selects `hal-posix-io` on Linux, the generated `mruby.c` contains POSIX-specific code and cannot be compiled on Windows. If you need amalgamated files for multiple platforms, generate them separately for each target platform (or cross-build configuration). ### Excluded Gems Binary gems (`mruby-bin-*`) are automatically excluded as they contain their own `main()` function. The amalgamation produces a library, not an executable. ## Example Configuration A minimal configuration for amalgamation: ```ruby # build_config/amalgam.rb MRuby::Build.new do |conf| conf.toolchain :gcc conf.gem core: 'mruby-compiler' conf.gem core: 'mruby-error' conf.gem core: 'mruby-eval' conf.gem core: 'mruby-array-ext' conf.gem core: 'mruby-string-ext' conf.gem core: 'mruby-hash-ext' conf.gem core: 'mruby-io' end ``` Generate with: ```console MRUBY_CONFIG=build_config/amalgam.rb rake amalgam ``` ## Output Sizes Typical sizes depend on included gems: - `mruby.h`: 200-500 KB - `mruby.c`: 2-4 MB ## Technical Details ### Header Processing - Include guards are stripped to allow concatenation - Headers are ordered by dependency (foundation types first) - Internal includes are commented out (already in `mruby.h`) ### Source Processing - Sources are concatenated in proper initialization order - X-macro headers (like `mruby/ops.h`) are inlined at each use - Local includes (`.cstub` files) are automatically inlined - Generated files (`mrblib.c`, `gem_init.c`) are included ### Gem Defines Gems that add preprocessor defines affecting core structures are automatically detected and included at the top of `mruby.h`. Supported patterns: `MRB_USE_*`, `MRB_UTF8_*`, `HAVE_MRUBY_*`. ### Build Order 1. Core sources (`src/*.c`) 2. Gem sources (`mrbgems/*/src/*.c` or `core/*.c`) 3. Generated mrblib (`build/*/mrblib/mrblib.c`) 4. Gem initialization (`build/*/mrbgems/gem_init.c`) nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/compile.md0000644000000000000000000000013215232371065021653 xustar0030 mtime=1785328181.912511136 30 atime=1785328183.359518359 30 ctime=1785328203.918095038 nghttp2-1.70.0/third-party/mruby/doc/guides/compile.md0000644000175100017510000004712715232371065022256 0ustar00runnerrunner # Compile mruby uses Rake to compile and cross-compile all libraries and binaries. ## Prerequisites To compile mruby out of the source code you need the following tools: - C Compiler (e.g. `gcc` or `clang`) - Linker (e.g. `gcc` or `clang`) - Archive utility (e.g. `ar`) - Ruby 2.5 or later (e.g. `ruby` or `jruby`) Optional: - Git (to update mruby source and integrate mrbgems easier) - C++ compiler (to use mrbgems which include `*.cpp`, `*.cxx`, `*.cc`) - Bison (to compile `mrbgems/mruby-compiler/core/parse.y`) - gperf (to compile `mrbgems/mruby-compiler/core/keywords`) Note that `bison` bundled with macOS is too old to compile `mruby`. Try `brew install bison` and follow the instruction shown to update the `$PATH` to compile `mruby`. We also encourage you to upgrade `ruby` on macOS in similar manner. ## Build To compile `mruby` with the default build configuration, just invoke `rake` inside of the mruby source root. To generate and execute the test tools call `rake test`. To clean all build files call `rake clean`. To see full command line on build, call `rake -v`. You can specify your own configuration file by the `MRUBY_CONFIG` environment variable (you can use `CONFIG` for shorthand for `MRUBY_CONFIG`). If the path doesn't exist, `build_config/${MRUBY_CONFIG}.rb` is used. The default configuration is defined in the `build_config/default.rb` file. Those build configuration files contain the build configuration of mruby, for example: ```ruby MRuby::Build.new do |conf| conf.toolchain :gcc end ``` All tools necessary to compile mruby can be set or modified here. ## Build Configuration We wish you submit a pull-request to `build_config/PLATFORM.rb`, once you created a new configuration for a new platform. Inside the configuration file, the following options can be configured based on your environment. ### Toolchains The mruby build system already contains a set of toolchain templates which configure the build environment for specific compiler infrastructures. #### GCC Toolchain configuration for the GNU C Compiler. ```ruby conf.toolchain :gcc ``` #### clang Toolchain configuration for the LLVM C Compiler clang. Mainly equal to the GCC toolchain. ```ruby conf.toolchain :clang ``` #### Visual Studio 2010, 2012 and 2013 Toolchain configuration for Visual Studio on Windows. If you use the [Visual Studio Command Prompt](), you normally do not have to specify this manually, since it gets automatically detected by our build process. ```ruby conf.toolchain :visualcpp ``` #### Android Toolchain configuration for Android. ```ruby conf.toolchain :android ``` Requires the custom standalone Android NDK and the toolchain path in `ANDROID_STANDALONE_TOOLCHAIN`. ### Binaries It is possible to select which tools should be compiled during the compilation process. For example, - `mruby` - `mirb` The configuration are done via `mrbgems`. See `Mrbgems` section. ### File Separator Some environments require a different file separator character. It is possible to set the character via `conf.file_separator`. ```ruby conf.file_separator = '/' ``` ### Name of library directory In some environments, the `libmruby.a` file requires a different directory name than `lib`. You can be changed to any name by the `conf.libdir_name` accessor. ```ruby conf.libdir_name = 'lib64' ``` Alternatively, it can be changed via the environment variable `MRUBY_SYSTEM_LIBDIR_NAME` when the `rake` command is run. ```console $ export MRUBY_SYSTEM_LIBDIR_NAME=lib64 $ rake clean all ``` NOTES: - This environment variable `MRUBY_SYSTEM_LIBDIR_NAME` does not affect `MRuby::CrossBuild`. In other words, if you want to change it for `MRuby::CrossBuild`, you must set it with `MRuby::CrossBuild#libdir_name=`. - If you want to switch this environment variable `MRUBY_SYSTEM_LIBDIR_NAME`, you must do `rake clean`. A bad usage example is shown below. ```console $ rake clean all $ rake MRUBY_SYSTEM_LIBDIR_NAME=lib64 install ``` ### C Compiler Configuration of the C compiler binary, flags and include paths. ```ruby conf.cc do |cc| cc.command = ... cc.flags = ... cc.include_paths = ... cc.defines = ... cc.option_include_path = ... cc.option_define = ... cc.compile_options = ... end ``` C Compiler has header searcher to detect installed library. If you need an include path of header file use `search_header_path`: ```ruby # Searches `iconv.h`. # If found it will return include path of the header file. # Otherwise it will return nil. fail 'iconv.h not found' unless conf.cc.search_header_path 'iconv.h' ``` If you need a full filename of header file use `search_header`: ```ruby # Searches `iconv.h`. # If found it will return full path of the header file. # Otherwise it will return nil. iconv_h = conf.cc.search_header 'iconv.h' print "iconv.h found: #{iconv_h}\n" ``` Header searcher uses compiler's `include_paths` by default. When you are using GCC toolchain (including clang toolchain since its base is gcc toolchain) it will use compiler specific include paths too. (For example `/usr/local/include`, `/usr/include`) If you need a special header search paths define a singleton method `header_search_paths` to C compiler: ```ruby def conf.cc.header_search_paths ['/opt/local/include'] + include_paths end ``` ### Linker Configuration of the Linker binary, flags and library paths. ```ruby conf.linker do |linker| linker.command = ... linker.flags = ... linker.flags_before_libraries = ... linker.libraries = ... linker.flags_after_libraries = ... linker.library_paths = ... linker.option_library = ... linker.option_library_path = ... linker.link_options = ... end ``` ### Archiver Configuration of the Archiver binary and flags. ```ruby conf.archiver do |archiver| archiver.command = ... archiver.archive_options = ... end ``` ### Parser Generator Configuration of the Parser Generator binary and flags. ```ruby conf.yacc do |yacc| yacc.command = ... yacc.compile_options = ... end ``` ### GPerf Configuration of the GPerf binary and flags. ```ruby conf.gperf do |gperf| gperf.command = ... gperf.compile_options = ... end ``` ### File Extensions ```ruby conf.exts do |exts| exts.object = ... exts.executable = ... exts.library = ... end ``` ### Preallocated Symbols Preallocated symbols are always enabled. Symbol IDs used in C source code (via `MRB_SYM()` etc.) are resolved to compile-time constants during the build process. ### Mrbgems `mruby` comes with the (sort of) packaging system named `mrbgems`. To specify `gem`, you can use `conf.gem` in the configuration file. ```ruby # Integrate a bundled Gem you see in `mrbgems` directory conf.gem :core => 'mruby-something' # Integrate a Gem from GitHub conf.gem :github => 'someone/mruby-another' # Integrate a mruby binary Gem conf.gem :core => 'mruby-bin-mruby' # Integrate a interactive mruby binary Gem conf.gem :core => 'mruby-bin-mirb' # Integrate GemBox (set of Gems) conf.gembox "default" ``` A GemBox is a set of Gems defined in `mrbgems/default.gembox` for example. It's just a set of `mrbgem` configurations. There is a `RubyGem` (gem for CRuby) named `mgem` that help you to manage `mrbgems`. Try `gem install mgem`. `mgem` can show you the list of registered `mrbgems`. See [doc/guides/mrbgems.md](mrbgems.md) for more option about mrbgems. ### Mrbtest Configuration Mrbtest build process. If you want `mrbtest.a` only, You should set `conf.build_mrbtest_lib_only` ```ruby conf.build_mrbtest_lib_only ``` ### Bintest Tests for mrbgem tools using CRuby. To have bintests place `*.rb` scripts to `bintest/` directory of mrbgems. See `mruby-bin-*/bintest/*.rb` if you need examples. If you want a temporary files use `tempfile` module of CRuby instead of `/tmp/`. You can enable it with following: ```ruby conf.enable_bintest ``` ### C++ ABI By default, mruby uses setjmp/longjmp to implement its exceptions. But it doesn't release C++ stack object correctly. To support mrbgems written in C++, mruby can be configured to use C++ exception. There are two levels of C++ exception handling. The one is `enable_cxx_exception` that enables C++ exception, but uses C ABI. The other is `enable_cxx_abi` where all files are compiled by C++ compiler. When you mix C++ code, C++ exception would be enabled automatically. If you need to enable C++ exception explicitly add the following: ```ruby conf.enable_cxx_exception ``` #### C++ exception disabling If your compiler does not support C++, and you want to ensure you don't use mrbgem written in C++, you can explicitly disable C++ exception, add following: ```ruby conf.disable_cxx_exception ``` and you will get an error when you try to use C++ gem. Note that it must be called before `enable_cxx_exception` or `gem` method. ### Debugging mode To enable debugging mode add the following: ```ruby conf.enable_debug ``` When debugging mode is enabled - Macro `MRB_DEBUG` would be defined. - Which means `mrb_assert()` macro is enabled. - Debug information of irep would be generated by `mrbc`. - Because `-g` flag would be added to `mrbc` runner. - You can have better backtrace of mruby scripts with this. ## Cross-Compilation mruby can also be cross-compiled from one platform to another. To achieve cross-compilation, the build configuration needs to contain an instance of `MRuby::CrossBuild`. This instance defines the compilation tools and flags for the target platform. An example could look like this: ```ruby MRuby::CrossBuild.new('32bit') do |conf| conf.toolchain :gcc conf.cc.flags << "-m32" conf.linker.flags << "-m32" end ``` All configuration options of `MRuby::Build` can also be used in `MRuby::CrossBuild`. You can find examples under the `build_config` directory. ### Mrbtest in Cross-Compilation In cross compilation, you can run `mrbtest` on an emulator if you have it by changing configuration of test runner. ```ruby conf.test_runner do |t| t.command = ... # set emulator. this value must be non nil or false t.flags = ... # set flags of emulator def t.run(bin) # override `run` if you need to change the behavior of it ... # `bin` is the full path of mrbtest end end ``` ## Build process During the build process the `build` directory will be created in the root directory. The structure of this directory will look like this: ``` +- build | +- host | +- LEGAL <- License description | +- bin <- Binaries (mirb, mrbc and mruby) | +- lib <- Libraries (libmruby.a and libmruby_core.a) | +- mrbc <- Minimal mrbc place | +- mrbgems <- Compilation result from mrbgems | +- mrblib <- Compilation result from mrblib | +- src <- Compilation result from C sources ``` The compilation workflow will look like this: - compile minimal `mrbc` from `src` and `mrblib` sources - compile all files under `src` (object files will be stored in `build/host/mrbc/src`) - compile `mruby-compiler` gem - create `build/host/mrbc/lib/libmruby_core.a` out of all object files (C only) - create `build/host/mrbc/bin/mrbc` via `mruby-bin-mrbc` gem - compile all files under `src` and store result in `build/host/src` - create `build/host/mrblib/mrblib.c` by compiling all `*.rb` files under `mrblib` with `build/host/mrbc/bin/mrbc` - compile `build/host/mrblib/mrblib.c` to `build/host/mrblib/mrblib.o` - create `build/host/lib/libmruby.a` out of all object files (C and Ruby) - compile (normal) mrbgems specified in the configuration file - create `build/host/lib/libmruby.a` from object files from gems and `libmruby_core.a` - create binary commands according to binary gems (e.g. `mirb` and `mruby`) - copy binaries under `build/host/bin` to `bin` directory ``` _____ _____ ______ ____ ____ _____ _____ ____ | CC |->|GEN |->|AR |->|CC |->|CC |->|AR |->|CC |->|CC | | *.c | |y.tab| |core.a| |mrbc| |*.rb| |lib.a| |mruby| |mirb| ----- ----- ------ ---- ---- ----- ----- ---- ``` ### Cross-Compilation In case of a cross-compilation to `i386` the `build` directory structure looks like this: ``` +- build | +- host | | | +- bin <- Native Binaries | | | +- lib <- Native Libraries | | | +- mrbgems | | | +- src | +- i386 | +- bin <- Cross-compiled Binaries | +- include <- Header Directory | +- lib <- Cross-compiled Libraries | +- mrbgems | +- mrblib | +- src ``` An extra directory is created for the target platform. In case you compile for `i386` a directory called `i386` is created under the build directory. The cross compilation workflow starts in the same way as the normal compilation by compiling all _native_ libraries and binaries, except for we don't have `host/mrbc` directory (`host` directory itself works as placeholder for `mrbc`). Afterwards the cross compilation process proceeds like this: - cross-compile all files under `src` and store result in `build/i386/src` - create `build/i386/lib/libmruby_core.a` out of C object files - create `build/i386/mrblib/mrblib.c` by compiling all `*.rb` files under `mrblib` with native `build/host/bin/mrbc` - cross-compile `build/i386/mrblib/mrblib.c` to `build/i386/mrblib/mrblib.o` - create `build/i386/lib/libmruby.a` from object files from gems and `libmruby_core.a` - create binary commands according to binary gems (e.g. `mirb` and `mruby`) - copy binaries under `build/host/bin` to `bin` directory ``` _______________________________________________________________ | Native Compilation for Host System | | _____ ______ _____ ____ ____ _____ | | | CC | -> |AR | -> |GEN | -> |CC | -> |CC | -> |AR | | | | *.c | |core.a| |y.tab| |mrbc| |*.rb| |lib.a| | | ----- ------ ----- ---- ---- ----- | --------------------------------------------------------------- || \||/ \/ ________________________________________________________________ | Cross Compilation for Target System | | _____ _____ _____ ____ ______ _____ | | | CC | -> |AR | -> |CC | -> |CC | -> |AR | -> |CC | | | | *.c | |lib.a| |mruby| |mirb| |core.a| |mrbc | | | ----- ----- ----- ---- ------ ----- | ---------------------------------------------------------------- ``` ## Build Configuration Examples ### Minimal Library To build a minimal mruby library you need to use the Cross Compiling feature due to the reason that there are functions (e.g. stdio) which can't be disabled for the main build. ```ruby MRuby::CrossBuild.new('minimal') do |conf| conf.toolchain :gcc conf.cc.defines << 'MRB_NO_STDIO' end ``` This configuration defines a cross compile build called 'minimal' which is using the GCC and compiles for the host machine. It also disables all usages of stdio and doesn't compile any binaries (e.g. `mrbc`). ## Test Environment mruby's build process includes a test environment. In case you start the testing of mruby, a native binary called `mrbtest` will be generated and executed. This binary contains all test cases which are defined under `test/t`. In case of a cross-compilation an additional cross-compiled `mrbtest` binary is generated. You can copy this binary and run on your target system. ## Embedding `mruby` in Your Application After the build, you will get `libmruby.a`. You can link it to your application. For compiler options and library path, you can use `mruby-config` command for convenience. `mruby-config` command prints the configuration used for `libmruby.a`. ```console $ mruby-config --help Usage: mruby-config [switches] switches: --cc print compiler name --cflags print flags passed to compiler --ld print linker name --ldflags print flags passed to linker --ldflags-before-libs print flags passed to linker before linked libraries --libs print linked libraries --libmruby-path print libmruby path --help print this help ``` For example, when you have a C source file (`c.c`) and try to compile and link it with `libmruby.a`, you can run the following command, ``` `mruby-config --cc --cflags` c.c `mruby-config --ldflags --libs` ``` When you use `make`, add following lines in `Makefile` ``` MRB_CONFIG = CFLAGS = `$(MRB_CONFIG) --cflags` LDFLAGS = `$(MRB_CONFIG) --ldflags` LIBS = `$(MRB_CONFIG) --libs` ``` ## Install To install the files in the `bin`, `include` and `lib` directories generated by the "host" build target into a system directory, do the following: ```console $ rake install ``` If there are multiple build targets in the build configuration file, to install the products of all build targets, do the following: ```console $ rake install:full ``` To install only one of several build targets, e.g., the "its-mine" build target, do the following: ```console $ rake install:full:its-mine ``` To install only the executable files, do the following: ```console $ rake install_bin # only "host" build target $ rake install:bin # all build targets $ rake install:bin:its-mine # only "its-mine" build target ``` ### Installation Directory The installation directory is `/usr/local` for the "host" build target and `/usr/local/mruby/` for the others. To change them, you can set the environment variable `PREFIX` or use `MRuby::Build#install_prefix = dir` in your build configuration file. The `PREFIX` environment variable affects all build targets and changes the `/usr/local` part. The `MRuby::Build#install_prefix` can be set for each individual build target. In this case, the environment variable `PREFIX` is ignored. Also, if the environment variable `DESTDIR` is set, it will prepend to the path obtained by `install_prefix` to determine the final write directory. This is intended for temporary file expansion by the user's package work. --- To summarize: - The default value of the environment variable `PREFIX` is `/usr/local`. - For the "host" build target, the default value of `MRuby::Build#install_prefix` is ``. - For a build target other than "host", the default value of `MRuby::Build#install_prefix` is `/mruby/`. - If the environment variable `DESTDIR` is set, the actual write directory is `/`. ### Excluded files In some cases there are files that you do not want to install. In such cases, add a file path filter to the array object `MRuby::Build#install_excludes` to exclude them. The following is an object that can be defined as a file path filter. The `path` variable that appears is a relative path based on `MRuby::Build#build_dir`. - string objects: files matched by `string.match?(path)` are excluded. - regexp object: files matched by `regexp.match?(path)` are excluded. - proc object: files which return true with `proc.call(path)` are excluded. ```ruby # exclude bin/mrbc conf.install_excludes << exefile("bin/mrbc") # exclude all files under lib/ directory conf.install_excludes << %r(^lib/) # exclude bin/mrbtest, but in this case it is recommended to use string instead of proc conf.install_excludes << proc { |path| path == exefile("bin/mrbtest") } ``` By default, it contains only a proc object to exclude `libmruby_core`. ## Tips - If you see compilation troubles, try `rake clean` first. nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/rom-method-table.md0000644000000000000000000000013215232371065023363 xustar0030 mtime=1785328181.913511141 30 atime=1785328183.361518369 30 ctime=1785328203.920849935 nghttp2-1.70.0/third-party/mruby/doc/guides/rom-method-table.md0000644000175100017510000003152315232371065023757 0ustar00runnerrunner # ROM Method Tables ROM method tables allow C methods to be registered using static data stored in ROM (read-only memory) rather than heap-allocated RAM. This saves significant memory on embedded systems where RAM is scarce. ## Motivation In a default mruby build, `mrb_open()` builds ~40 classes with ~700+ method entries at startup. Each method entry is heap-allocated via individual `mrb_define_method_id()` calls. On a constrained MCU, this consumes ~14KB of RAM for method table metadata alone. ROM method tables eliminate this cost by placing method metadata in static `const` data at compile time. Only runtime mutations (e.g., reopening a class to add methods) trigger heap allocation. ## Architecture ### Chained Layers Each class has a method table (`mt`) pointer to a linked list of `mrb_mt_tbl` layers: ``` String.mt -> [mutable layer] -> [string_ext ROM] -> [string_core ROM] -> NULL ``` **Lookup** walks the chain front-to-back, returning the first match. The method cache makes repeated lookups O(1), so the chain walk only occurs on cache misses. **Mutation** uses copy-on-write (COW): if the top layer is read-only, a new mutable layer is created in front of it. The ROM data is never modified. ``` Before: String.mt -> [string_ext ROM] -> [string_core ROM] -> NULL After String.define_method(:foo): String.mt -> [mutable: foo] -> [string_ext ROM] -> [string_core ROM] -> NULL ``` ### Memory Layout Each `mrb_mt_tbl` stores method entries as an array of `mrb_mt_entry` structs, each combining a function pointer, a symbol key, and flags: ``` ptr -> [ entry[0] | entry[1] | ... | entry[N-1] ] |<-- mrb_mt_entry: { val, key, flags } -->| ``` Values are `union mrb_mt_ptr` (function pointer or proc pointer). Keys are pure `mrb_sym` (no flag encoding). Flags are a separate `uint32_t` field that stores visibility, func/proc type, and argument spec. Entries are searched linearly, so source code order does not matter. The method cache makes repeated lookups O(1), so the linear scan only occurs on cache misses. ### Per-State Wrappers The `const mrb_mt_entry[]` arrays are truly static and shared across the process. However, the `mrb_mt_tbl` wrapper (which carries the `next` pointer for chaining) is heap-allocated per `mrb_state` by `MRB_MT_INIT_ROM()`. This allows multiple `mrb_state` instances in the same process to each have independent method table chains, even when linking to the same const entries. ## How to Define a ROM Method Table ### Step 1: Define the Static Data Include `` (which provides `mrb_mt_entry`, `MRB_MT_ENTRY()`, and flag constants) and define the ROM entries: ```c #include static const mrb_mt_entry my_rom_entries[] = { MRB_MT_ENTRY(my_method_a, MRB_SYM(method_a), MRB_ARGS_REQ(1)), MRB_MT_ENTRY(my_method_b, MRB_SYM(method_b), MRB_ARGS_NONE()), MRB_MT_ENTRY(my_method_eq, MRB_OPSYM(eq), MRB_ARGS_REQ(1)), }; ``` ### Step 2: Register in the Init Function Replace `mrb_define_method_id()` calls with a single `MRB_MT_INIT_ROM()` call: ```c void mrb_mruby_mygem_gem_init(mrb_state *mrb) { struct RClass *c = mrb_define_class_id(mrb, MRB_SYM(MyClass), mrb->object_class); MRB_MT_INIT_ROM(mrb, c, my_rom_entries); } ``` `MRB_MT_INIT_ROM()` allocates a per-state wrapper and pushes the ROM layer onto the class's method table chain. ### Step 3: Verify Build and run the test suite. ROM tables are semantically transparent to Ruby code. ## Reference ### Data Types Defined in `include/mruby/class.h`: ```c union mrb_mt_ptr { const struct RProc *proc; mrb_func_t func; }; typedef struct mrb_mt_entry { union mrb_mt_ptr val; mrb_sym key; /* pure symbol ID (no flags packed) */ uint32_t flags; /* method flags + aspec */ } mrb_mt_entry; typedef struct mrb_mt_tbl { int size; int alloc; /* bit 30: MRB_MT_READONLY_BIT */ mrb_mt_entry *ptr; struct mrb_mt_tbl *next; /* next (lower-priority) layer, or NULL */ } mrb_mt_tbl; ``` ### Macros ```c /* ROM table entry: 3rd param is MRB_ARGS_*() optionally OR'd with MRB_MT_PRIVATE. The macro OR's in MRB_MT_FUNC automatically. */ #define MRB_MT_ENTRY(fn, sym, flags) \ { { .func = (fn) }, (sym), (flags) | MRB_MT_FUNC } /* Extract aspec from combined flags */ #define MRB_MT_ASPEC(flags) ((mrb_aspec)((flags) & 0xffffff)) /* Allocate a per-state ROM wrapper and push onto class method chain */ #define MRB_MT_INIT_ROM(mrb, cls, entries) \ mrb_mt_init_rom(mrb, cls, entries, \ (int)(sizeof(entries)/sizeof(entries[0]))) ``` ### Flags | Flag | Value | Description | | ---------------- | ------- | ----------------------------------- | | `MRB_MT_FUNC` | (1<<24) | C function (auto-set by macro) | | `MRB_MT_PUBLIC` | 0 | Public visibility (default) | | `MRB_MT_PRIVATE` | (1<<25) | Private visibility (in entry param) | The third parameter to `MRB_MT_ENTRY()` is an `MRB_ARGS_*()` expression optionally OR'd with `MRB_MT_PRIVATE`. The aspec value occupies bits 0-23 and the visibility flag occupies bit 25; these ranges do not overlap, so the values are simply OR'd together. `MRB_MT_FUNC` is set automatically. The no-arg optimization is derived at runtime from `aspec == 0` (`MRB_ARGS_NONE()`). **How to write entries:** - **`MRB_MT_ENTRY(fn, sym, MRB_ARGS_*(...))`**: Public method. - **`MRB_MT_ENTRY(fn, sym, MRB_ARGS_*(...) | MRB_MT_PRIVATE)`**: Private method. - Use the same `MRB_ARGS_*()` macros as `mrb_define_method_id()`. ### Symbol Macros Use the presym macros for keys. See `doc/guides/symbol.md` for the full list: ```c MRB_SYM(size) /* size */ MRB_SYM_B(chomp) /* chomp! */ MRB_SYM_Q(frozen) /* frozen? */ MRB_SYM_E(name) /* name= */ MRB_OPSYM(add) /* + */ MRB_OPSYM(eq) /* == */ MRB_OPSYM(aref) /* [] */ MRB_OPSYM(aset) /* []= */ MRB_OPSYM(cmp) /* <=> */ MRB_IVSYM(name) /* @name */ ``` ### API ```c void mrb_mt_init_rom(mrb_state *mrb, struct RClass *c, const mrb_mt_entry *entries, int size); ``` Allocates a per-state `mrb_mt_tbl` wrapper for the const entries and pushes it onto the class's method table chain. The wrapper is tracked in `mrb->rom_mt` and freed at `mrb_close()`. Use the `MRB_MT_INIT_ROM` macro to auto-compute the size. Multiple calls push additional layers, which is how extension gems add methods to core classes. ## Entry Correspondence Each `MRB_MT_ENTRY()` bundles a function pointer with its method name and flags in a single line. Their order in the source code does not matter, but keeping related methods together improves readability. **Method aliases** (two names for the same function) are expressed as separate entries sharing the same function pointer: ```c static const mrb_mt_entry str_rom_entries[] = { MRB_MT_ENTRY(mrb_str_size, MRB_SYM(size), MRB_ARGS_NONE()), MRB_MT_ENTRY(mrb_str_size, MRB_SYM(length), MRB_ARGS_NONE()), }; ``` ## Conditional Methods Methods that depend on build configuration (e.g., `MRB_NO_FLOAT`) can use `#ifdef` directly inside the ROM entries array. The `sizeof` in `MRB_MT_INIT_ROM()` automatically adjusts to the number of entries that survive preprocessing: ```c static const mrb_mt_entry integer_rom_entries[] = { MRB_MT_ENTRY(int_to_s, MRB_SYM(to_s), MRB_ARGS_OPT(1)), MRB_MT_ENTRY(int_add, MRB_OPSYM(add), MRB_ARGS_REQ(1)), #ifndef MRB_NO_FLOAT MRB_MT_ENTRY(int_to_f, MRB_SYM(to_f), MRB_ARGS_NONE()), #endif }; ``` For conditional methods on a **different class**, use a separate ROM table wrapped in the `#ifdef`: ```c #ifndef MRB_NO_FLOAT static const mrb_mt_entry float_rom_entries[] = { ... }; #endif void mrb_init_numeric(mrb_state *mrb) { MRB_MT_INIT_ROM(mrb, integer, integer_rom_entries); #ifndef MRB_NO_FLOAT MRB_MT_INIT_ROM(mrb, fl, float_rom_entries); #endif } ``` ## Extension Gems Extension gems use exactly the same pattern. Since gems are initialized after core, calling `MRB_MT_INIT_ROM()` pushes the gem's ROM layer in front of the core ROM layer: ```c /* mrbgems/mruby-string-ext/src/string.c */ static const mrb_mt_entry string_ext_rom_entries[] = { ... }; void mrb_mruby_string_ext_gem_init(mrb_state *mrb) { struct RClass *s = mrb->string_class; MRB_MT_INIT_ROM(mrb, s, string_ext_rom_entries); } ``` After initialization, String's method table chain looks like: ``` String.mt -> [string_ext ROM, 53 methods] -> [string_core ROM, 46 methods] -> NULL ``` A gem may also define ROM tables for multiple classes: ```c void mrb_mruby_mygem_gem_init(mrb_state *mrb) { MRB_MT_INIT_ROM(mrb, mrb->string_class, string_mygem_rom_entries); MRB_MT_INIT_ROM(mrb, mrb->integer_class, integer_mygem_rom_entries); } ``` ## Methods That Cannot Use ROM Tables Some methods must remain as `mrb_define_method_id()` calls: - **Class methods** (`mrb_define_class_method_id()`): ROM tables register instance methods only. - **Module functions** (`mrb_define_module_function_id()`): Same reason. - **Methods requiring `mrb_state*` at definition time**: For example, methods that create frozen RProc objects during init. - **Methods on dynamically created classes**: Classes created at init time (not stored in `mrb->xxx_class`) that require `mrb_define_class()` to obtain the class pointer. - **Cross-class methods** (methods on a class the gem does not own): Each ROM table adds a 16-byte `mrb_mt_tbl` layer to the target class's chain. For 1-2 methods, this overhead exceeds the savings. Use `mrb_define_method_id()` instead -- cross-class methods share the target class's existing mutable layer. These methods are added after `MRB_MT_INIT_ROM()` and go into the mutable layer that sits in front of the ROM chain. ## Runtime Behavior ### Open Classes (COW) Ruby's open classes work transparently. When a Ruby program or C code adds a method to a class with a ROM table, the COW mechanism creates a mutable layer: ```ruby class String def my_custom_method 42 end end "hello".my_custom_method #=> 42 "hello".size #=> 5 (still found in ROM layer) ``` ### Method Removal `remove_method` works on ROM methods using a tombstone marker. When a method in a ROM layer is removed, a special entry (`MRB_MT_FUNC` flag with `func=NULL`) is inserted into the mutable layer. The `mt_get()` lookup treats this marker as "not found" and stops searching the chain, effectively hiding the ROM entry. Unlike `undef_method` (which blocks superclass lookup), `remove_method`'s tombstone allows the superclass method to be found. `undef_method` uses a different tombstone (`proc=NULL` without `MRB_MT_FUNC`), which is returned by `mt_get()` so the caller raises NoMethodError without searching the superclass. ### Class Duplication `Class.dup` shares the ROM chain. The duplicated class gets an empty mutable layer pointing to the same ROM layers as the original. No ROM data is copied. ### Garbage Collection ROM layers are skipped during GC mark and sweep phases. Only mutable layers are scanned for live RProc references and freed when the class is collected. ROM wrappers are freed at `mrb_close()` via the `mrb->rom_mt` tracking list. ### Memory Measurement `mrb_class_mt_memsize()` reports only mutable layer memory. ROM wrappers are tracked separately and not counted per-class. ## Converting Existing Code To convert existing `mrb_define_method_id()` calls to a ROM table: 1. **Count** the number of method definitions that can be converted. 2. **Create** the ROM entries array using `MRB_MT_ENTRY()`. 3. **Move** each `mrb_define_method_id()` call into the entries: - `MRB_MT_ENTRY(func, sym, aspec)` where: - `func` is the function pointer - `sym` is the symbol macro (e.g., `MRB_SYM(name)`) - `aspec` is the original `MRB_ARGS_*()` macro - For private methods, OR `MRB_MT_PRIVATE` into the aspec: `MRB_MT_ENTRY(func, sym, aspec | MRB_MT_PRIVATE)` 4. **Replace** the calls with `MRB_MT_INIT_ROM(mrb, c, entries)`. 5. **Keep** any methods that cannot be converted (see above) as individual `mrb_define_method_id()` calls after the ROM init. 6. **Build and test**: `rake CONFIG=host-debug -j24 all test:run:serial` ### Before ```c void mrb_mruby_foo_gem_init(mrb_state *mrb) { struct RClass *foo = mrb_define_class_id(mrb, MRB_SYM(Foo), mrb->object_class); mrb_define_method_id(mrb, foo, MRB_SYM(bar), foo_bar, MRB_ARGS_REQ(1)); mrb_define_method_id(mrb, foo, MRB_SYM(baz), foo_baz, MRB_ARGS_NONE()); mrb_define_method_id(mrb, foo, MRB_OPSYM(eq), foo_eq, MRB_ARGS_REQ(1)); } ``` ### After ```c static const mrb_mt_entry foo_rom_entries[] = { MRB_MT_ENTRY(foo_bar, MRB_SYM(bar), MRB_ARGS_REQ(1)), MRB_MT_ENTRY(foo_baz, MRB_SYM(baz), MRB_ARGS_NONE()), MRB_MT_ENTRY(foo_eq, MRB_OPSYM(eq), MRB_ARGS_REQ(1)), }; void mrb_mruby_foo_gem_init(mrb_state *mrb) { struct RClass *foo = mrb_define_class_id(mrb, MRB_SYM(Foo), mrb->object_class); MRB_MT_INIT_ROM(mrb, foo, foo_rom_entries); } ``` nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/mrbgems.md0000644000000000000000000000013215232371065021657 xustar0030 mtime=1785328181.912511136 30 atime=1785328183.360518364 30 ctime=1785328203.923585273 nghttp2-1.70.0/third-party/mruby/doc/guides/mrbgems.md0000644000175100017510000003674315232371065022264 0ustar00runnerrunner # mrbgems mrbgems is a library manager to integrate C and Ruby extensions in an easy and standardised way into mruby. Conventionally, each mrbgem name is prefixed by `mruby-`, e.g. `mruby-time` for a gem that provides `Time` class functionality. ## Usage You have to activate mrbgems explicitly in your build configuration. To add a gem, add the following line to your build configuration file, for example: ```ruby conf.gem '/path/to/your/gem/dir' ``` You can also use a relative path to specify a gem. ```ruby conf.gem 'examples/mrbgems/ruby_extension_example' ``` In that case, - if your build configuration file is in the `build_config` directory, it's relative from `MRUBY_ROOT`. - otherwise, it is relative from the directory where your build configuration is. A remote GIT repository location for a GEM is also supported: ```ruby conf.gem :git => 'https://github.com/masuidrive/mrbgems-example.git', :branch => 'master' conf.gem :github => 'masuidrive/mrbgems-example', :branch => 'master' conf.gem :bitbucket => 'mruby/mrbgems-example', :branch => 'master' ``` NOTE: `:bitbucket` option supports only git. Hg is unsupported in this version. You can specify the subdirectory of the repository with `:path` option: ```ruby conf.gem github: 'mruby/mruby', path: 'mrbgems/mruby-socket' ``` To use mrbgem from [mgem-list](https://github.com/mruby/mgem-list) use `:mgem` option: ```ruby conf.gem :mgem => 'mruby-yaml' conf.gem :mgem => 'yaml' # 'mruby-' prefix could be omitted ``` For specifying the commit hash to checkout use `:checksum_hash` option: ```ruby conf.gem mgem: 'mruby-redis', checksum_hash: '3446d19fc4a3f9697b5ddbf2a904f301c42f2f4e' ``` If there are missing dependencies, mrbgem dependencies solver will reference mrbgem from the core or mgem-list. Note that if more than one git-based gem has the same base name (i.e. the default checkout directory name), it is (now) an error **UNLESS** they have the same repository URL, branch name and commit-id (i.e. checksum hash). You can bypass this by explicitly importing your preferred version **first** and setting the `canonical:` option to `true`: ```ruby conf.gem github: 'me/mruby-yaml', branch: 'my-hacked-branch', canonical: true ``` If you do this, the system will (mostly) silently ignore other attempts to clone a gem with this name. Note that this only affects cloning the gem from git. It does not resolve version conflicts. If the version as specified in the gem's rakefile is incompatible with a dependency, your build will still fail. ### Tweak the gem in your build configuration file You can give blocks in the `conf.gem` call to make adjustments for environments where the original gem does not expect them: ```ruby conf.gem core: "mruby-bin-mirb" do |g| # For cross build to NetBSD g.linker.libraries = %w(edit termcap) end ``` However, it should be used with caution, as it may deviate from the intent of the gem's author. ### Gem Testing If you enable unit tests in your build with `enable_test`, tests will be generated for all gems and their dependencies by default. If necessary, it is possible to suppress tests for a specific gem like so: ```ruby conf.gem 'mruby-noisygem' do |g| g.skip_test = true end ``` However, it is considered best practice to leave all tests enabled whenever possible. A warning message will be generated for each gem with disabled tests. ## GemBox There are instances when you wish to add a collection of mrbgems into mruby at once, or be able to substitute mrbgems based on configuration, without having to add each gem to your build configuration file. A packaged collection of mrbgems is called a GemBox. A GemBox is a file that contains a list of mrbgems to load into mruby, in the same format as if you were adding them to the build config via `config.gem`, but wrapped in an `MRuby::GemBox` object. GemBoxes are loaded into mruby via `config.gembox 'boxname'`. Below we have created a GemBox containing `mruby-time` and `mrbgems-example`: ```ruby MRuby::GemBox.new do |conf| conf.gem "#{root}/mrbgems/mruby-time" conf.gem :github => 'masuidrive/mrbgems-example' end ``` As mentioned, the GemBox uses the same conventions as `MRuby::Build`. The GemBox must be saved with a `.gembox` extension inside the `mrbgems` directory to be picked up by mruby. To use this example GemBox, we save it as `custom.gembox` inside the `mrbgems` directory in mruby, and add the following to your build configuration file inside the build block: ```ruby conf.gembox 'custom' ``` This will cause the `custom` GemBox to be read in during the build process, adding `mruby-time` and `mrbgems-example` to the build. If you want, you can put GemBox outside the mruby directory. In that case you must specify an absolute path like below. ```ruby conf.gembox "#{ENV["HOME"]}/mygemboxes/custom" ``` There are two GemBoxes that ship with mruby: [default](../../mrbgems/default.gembox) and [full-core](../../mrbgems/full-core.gembox). The [default](../../mrbgems/default.gembox) GemBox contains several core components of mruby, and [full-core](../../mrbgems/full-core.gembox) contains every gem found in the `mrbgems` directory. ## GEM Structure The maximal GEM structure looks like this: ``` +- GEM_NAME <- Name of GEM | +- README.md <- Readme for GEM | +- mrbgem.rake <- GEM Specification | +- include/ <- Header for Ruby extension (will exported) | +- mrblib/ <- Source for Ruby extension | +- src/ <- Source for C extension | +- tools/ <- Source for Executable (in C) | +- test/ <- Test code (Ruby) ``` The `mrblib` directory contains pure Ruby files to extend mruby. The `src` directory contains C/C++ files to extend mruby. The `include` directory contains C/C++ header files. The `test` directory contains C/C++ and pure Ruby files for testing purposes which will be used by `mrbtest`. `mrbgem.rake` contains the specification to compile C and Ruby files. `README.md` is a short description of your GEM. ## Build process mrbgems expects a specification file called `mrbgem.rake` inside of your GEM directory. A typical GEM specification could look like this for example: ```ruby MRuby::Gem::Specification.new('c_and_ruby_extension_example') do |spec| spec.license = 'MIT' spec.author = 'mruby developers' spec.summary = 'Example mrbgem using C and Ruby' end ``` The mrbgems build process will use this specification to compile Object and Ruby files. The compilation results will be added to `lib/libmruby.a`. This file exposes the GEM functionality to tools like `mruby` and `mirb`. The following properties can be set inside your `MRuby::Gem::Specification` for information purpose: - `spec.license` or `spec.licenses` (A single license or a list of them under which this GEM is licensed) - `spec.author` or `spec.authors` (Developer name or a list of them) - `spec.version` (Current version) - `spec.description` (Detailed description) - `spec.summary` - One line short description of mrbgem. - Printed in build summary of rake when set. - `spec.homepage` (Homepage) - `spec.requirements` (External requirements as information for user) The `license` and `author` properties are required in every GEM! In case your GEM is depending on other GEMs please use `spec.add_dependency(gem, *requirements[, default_get_info])` like: ```ruby MRuby::Gem::Specification.new('c_and_ruby_extension_example') do |spec| spec.license = 'MIT' spec.author = 'mruby developers' # Add GEM dependency mruby-parser. # The version must be between 1.0.0 and 1.5.2 . spec.add_dependency('mruby-parser', '>= 1.0.0', '<= 1.5.2') # Use any version of mruby-uv from GitHub. spec.add_dependency('mruby-uv', '>= 0.0.0', :github => 'mattn/mruby-uv') # Use latest mruby-onig-regexp from GitHub. (version requirements can be omitted) spec.add_dependency('mruby-onig-regexp', :github => 'mattn/mruby-onig-regexp') # You can add extra mgems active only on test spec.add_test_dependency('mruby-process', :github => 'iij/mruby-process') end ``` The version requirements and default gem information are optional. Version requirement supports following operators: - '=': is equal - '!=': is not equal - '>': is greater - '<': is lesser - '>=': is equal or greater - '<=': is equal or lesser - '~>': is equal or greater and is lesser than the next major version - example 1: '~> 2.2.2' means '>= 2.2.2' and '< 2.3.0' - example 2: '~> 2.2' means '>= 2.2.0' and '< 3.0.0' When more than one version requirements is passed, the dependency must satisfy all of it. You can have default gem to use as dependency when it's not defined in your build configuration. When the last argument of `add_dependency` call is `Hash`, it will be treated as default gem information. Its format is same as argument of method `MRuby::Build#gem`, except that it can't be treated as path gem location. When a special version of dependency is required, use `MRuby::Build#gem` in the build configuration to override default gem. If you have conflicting GEMs use the following method: - `spec.add_conflict(gem, *requirements)` - The `requirements` argument is same as in `add_dependency` method. like following code: ```ruby MRuby::Gem::Specification.new 'some-regexp-binding' do |spec| spec.license = 'BSD' spec.author = 'John Doe' spec.add_conflict 'mruby-onig-regexp', '> 0.0.0' spec.add_conflict 'mruby-hs-regexp' spec.add_conflict 'mruby-pcre-regexp' spec.add_conflict 'mruby-regexp-pcre' end ``` In case your GEM has more complex build requirements you can use the following options additionally inside your GEM specification: - `spec.cc.flags` (C compiler flags) - `spec.cc.defines` (C compiler defines) - `spec.cc.include_paths` (C compiler include paths) - `spec.linker.flags` (Linker flags) - `spec.linker.libraries` (Linker libraries) - `spec.linker.library_paths` (Linker additional library path) - `spec.bins` (Generate binary file) - `spec.rbfiles` (Ruby files to compile) - `spec.objs` (Object files to compile) - `spec.test_rbfiles` (Ruby test files for integration into mrbtest) - `spec.test_objs` (Object test files for integration into mrbtest) - `spec.test_preload` (Initialization files for mrbtest) You also can use `spec.mruby.cc` and `spec.mruby.linker` to add extra global parameters for the compiler and linker. ### include_paths and dependency Your GEM can export include paths to another GEMs that depends on your GEM. By default, `/...absolute path.../{GEM_NAME}/include` will be exported. So it is recommended not to put GEM's local header files on include/. These exports are transitive. For example: when B depends on C and A depends on B, A will get include paths exported by C. Exported `include_paths` are automatically appended to GEM local `include_paths` by rake. You can use `spec.export_include_paths` accessor if you want more complex build. ### Settings for GEM build commands/tasks When the block argument passed to `MRuby::Gem::Specification.new` is executed, the GEM build commands/tasks for the `MRuby::Build` instance may not yet be finalized. In most cases, modifying the GEM build commands/tasks within the block passed to `MRuby::Gem::Specification.new` is not a problem. However, you may need to perform GEM build commands/tasks after the GEM build commands/tasks for the `MRuby::Build` instance have been finalized. In such cases, you can achieve this by passing a block argument to `MRuby::Gem::Specification#build_settings` within the block passed to `MRuby::Gem::Specification.new`. ```ruby spec.build_settings do spec.cc.flags << "-any_flags" end ``` **NOTE**: Using the `build_settings` method will cause GEM's all build command settings directly written in the block passed to `MRuby::Gem::Specification.new` to be ignored. ## C Extension mruby can be extended with C. This is possible by using the C API to integrate C libraries into mruby. ### Preconditions mrbgems expects that you have implemented a C method called `mrb_YOURGEMNAME_gem_init(mrb_state)`. `YOURGEMNAME` will be replaced by the name of your GEM. If you call your GEM `c_extension_example`, your initialisation method could look like this: ```c void mrb_c_extension_example_gem_init(mrb_state* mrb) { struct RClass *class_cextension = mrb_define_module(mrb, "CExtension"); mrb_define_class_method(mrb, class_cextension, "c_method", mrb_c_method, MRB_ARGS_NONE()); } ``` ### Finalize mrbgems expects that you have implemented a C method called `mrb_YOURGEMNAME_gem_final(mrb_state)`. `YOURGEMNAME` will be replaced by the name of your GEM. If you call your GEM `c_extension_example`, your finalizer method could look like this: ```c void mrb_c_extension_example_gem_final(mrb_state* mrb) { free(someone); } ``` ### Example ``` +- c_extension_example/ | +- README.md (Optional) | +- src/ | | | +- example.c <- C extension source | +- test/ | | | +- example.rb <- Test code for C extension | +- mrbgem.rake <- GEM specification ``` ## Ruby Extension mruby can be extended with pure Ruby. It is possible to override existing classes or add new ones in this way. Put all Ruby files into the `mrblib` directory. ### Preconditions none ### Example ``` +- ruby_extension_example/ | +- README.md (Optional) | +- mrblib/ | | | +- example.rb <- Ruby extension source | +- test/ | | | +- example.rb <- Test code for Ruby extension | +- mrbgem.rake <- GEM specification ``` ## C and Ruby Extension mruby can be extended with C and Ruby at the same time. It is possible to override existing classes or add new ones in this way. Put all Ruby files into the `mrblib` directory and all C files into the `src` directory. mruby codes under `mrblib` directory would be executed after gem init C function is called. Make sure _mruby script_ depends on _C code_ and _C code_ doesn't depend on _mruby script_. ### Preconditions See C and Ruby example. ### Example ``` +- c_and_ruby_extension_example/ | +- README.md (Optional) | +- mrblib/ | | | +- example.rb <- Ruby extension source | +- src/ | | | +- example.c <- C extension source | +- test/ | | | +- example.rb <- Test code for C and Ruby extension | +- mrbgem.rake <- GEM specification ``` ## Binary gems Some gems can generate executables under `bin` directory. Those gems are called binary gems. Names of binary gems are conventionally prefixed by `mruby-bin`, e.g. `mruby-bin-mirb` and `mruby-bin-strip`. To specify the name of executable, you need to specify `spec.bins` in the `mrbgem.rake`. The entry point `main()` should be in the C source file under `tools//*.c` where `` is a name of the executable. C files under the `` directory are compiled and linked to the executable, but not included in `libmruby.a`, whereas files under `mrblib` and `src` are. It is strongly recommended not to include `mrblib` and `src` directories in the binary gems, to separate normal gems and binary gems. ### Example ``` +- mruby-bin-example/ | +- README.md (Optional) | +- bintest/ | | | +- example.rb <- Test code for binary gem | +- mrbgem.rake <- Gem specification | +- mrblib/ <- Source for Ruby extension (Optional) | +- src/ <- Source for C extension (Optional) | +- tools/ | +- example/ <- Executable name directory | +- example.c <- Source for Executable (includes main) ``` nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/language.md0000644000000000000000000000013215232371065022006 xustar0030 mtime=1785328181.912511136 30 atime=1785328183.360518364 30 ctime=1785328203.931904136 nghttp2-1.70.0/third-party/mruby/doc/guides/language.md0000644000175100017510000003246715232371065022412 0ustar00runnerrunner # mruby Language Features This guide describes the Ruby language features supported by mruby 4.0. mruby implements a subset of the Ruby language, optimized for embedded use. For a list of specific behavioral differences, see [limitations.md](../limitations.md). **If you are coming from CRuby**, note these major differences upfront: - No `require` or `load` — all code is linked at build time - No `defined?` keyword — use `respond_to?`, `const_defined?`, etc. - No refinements (`refine`, `using`) - No `Encoding` class — UTF-8 opt-in via `MRB_UTF8_STRING` - Fibers cannot yield across C function boundaries - Integer size varies by platform and boxing mode - Operators cannot be overridden by user code See [Key Differences from CRuby](#key-differences-from-cruby) for the full list. ## Syntax ### Keywords mruby supports the following keywords: `BEGIN`, `END`, `alias`, `and`, `begin`, `break`, `case`, `class`, `def`, `do`, `else`, `elsif`, `end`, `ensure`, `false`, `for`, `if`, `in`, `module`, `next`, `nil`, `not`, `or`, `redo`, `rescue`, `retry`, `return`, `self`, `super`, `then`, `true`, `undef`, `unless`, `until`, `when`, `while`, `yield` Magic variables: `__FILE__`, `__LINE__`, `__ENCODING__`, `__method__` **Not supported:** `defined?` (use `respond_to?`, `const_defined?`, etc. instead), `refinements` (`using`, `refine`). ### Classes and Modules ```ruby class Animal attr_accessor :name def initialize(name) @name = name end def speak "..." end end class Dog < Animal def speak "Woof!" end end module Greetable def greet "Hello, I'm #{name}" end end class Dog include Greetable end ``` All standard class and module features are supported: inheritance, `include`, `prepend`, `extend`, `attr_reader`/`attr_writer`/ `attr_accessor`, `public`/`private`/`protected` visibility, class variables (`@@var`), class methods, and `super`. ### Methods ```ruby # Required, optional, rest, post-rest, keyword, and block arguments def example(a, b = 1, *rest, last, key:, opt_key: nil, **kwargs, &block) end # Endless method definition def double(x) = x * 2 ``` ### Blocks and Procs ```ruby [1, 2, 3].each { |n| puts n } [1, 2, 3].each do |n| puts n end square = Proc.new { |x| x * x } square = proc { |x| x * x } double = lambda { |x| x * 2 } double = ->(x) { x * 2 } ``` ### Control Flow ```ruby # if/unless (both statement and modifier forms) if condition # ... elsif other # ... else # ... end result = value if condition result = value unless condition # case/when case obj when String then "string" when Integer then "integer" else "other" end # Loops while condition # ... end until condition # ... end for item in collection # ... end # Loop control break # exit loop next # skip to next iteration redo # restart current iteration retry # restart begin/rescue block ``` ### Exception Handling ```ruby begin risky_operation rescue ArgumentError => e handle_arg_error(e) rescue StandardError => e handle_error(e) ensure cleanup end raise "something went wrong" raise ArgumentError, "bad argument" ``` **Note:** `raise` without arguments in a `rescue` clause does not re-raise the current exception. Capture and re-raise explicitly: ```ruby begin risky_operation rescue => e log(e) raise e # explicit re-raise required end ``` ### Strings ```ruby "double-quoted with #{interpolation}" 'single-quoted literal' heredoc = <<~HEREDOC indented heredoc with #{interpolation} HEREDOC ``` ### Regular Expressions Regular expressions require an external gem such as `mruby-regexp-pcre` or `mruby-onig-regexp`. Without a regexp gem, `Regexp` literals (`/pattern/`) are not available. ### Pattern Matching (Limited) Only rightward assignment with simple variable binding is supported: ```ruby expr => var # assigns expr to var ``` `case/in` syntax, array/hash patterns, guard clauses, pin operator, find patterns, and alternative patterns are **not** supported. ## Numeric Types mruby's numeric type sizes depend on the boxing mode and platform. ### Integer | Configuration | Range | | -------------------------------------- | ---------------- | | 64-bit word boxing (default on 64-bit) | roughly +/- 2^62 | | 32-bit word boxing (default on 32-bit) | roughly +/- 2^30 | | NaN boxing (64-bit only) | -2^31 to 2^31-1 | Integer overflow raises a `RangeError` unless the `mruby-bigint` gem is included, in which case integers automatically promote to arbitrary precision. ### Float By default, `Float` uses 64-bit `double`. Compile-time options: - `MRB_USE_FLOAT32`: use 32-bit `float` instead - `MRB_NO_FLOAT`: disable floating-point entirely With word boxing on 64-bit, many float values are stored inline (without heap allocation) using a rotation encoding. ### Additional Numeric Types (via gems) - **Rational** (`mruby-rational`): exact rational arithmetic - **Complex** (`mruby-complex`): complex number support - **Bigint** (`mruby-bigint`): arbitrary-precision integers ## Core Classes These classes are always available in mruby (no gem required): | Class | Notes | | ------------- | -------------------------------------- | | Object | Base class for all objects | | Module | Module definition and mixin | | Class | Class definition and instantiation | | NilClass | Singleton `nil` | | TrueClass | Singleton `true` | | FalseClass | Singleton `false` | | Integer | Fixed-precision integer | | Float | Floating-point (unless `MRB_NO_FLOAT`) | | Symbol | Interned identifier | | String | Mutable byte string | | Array | Ordered collection | | Hash | Key-value mapping | | Range | Interval representation | | Proc | Closure / callable object | | Exception | Exception hierarchy root | | StandardError | Common error base | ### Core Modules | Module | Notes | | ---------- | ----------------------------------------- | | Kernel | Core methods (`puts`, `p`, `raise`, etc.) | | Comparable | Comparison operators via `<=>` | | Enumerable | Collection iteration methods | ## Standard Library (via gemboxes) mruby's standard library is organized into gemboxes. The `default` gembox includes all of the below. Use this table to find which gembox provides the class or feature you need: ### Classes and Modules | Class/Module | Gembox | Gem | | --------------------- | ---------- | ----------------- | | Fiber | stdlib | mruby-fiber | | Enumerator | stdlib | mruby-enumerator | | Enumerator::Lazy | stdlib | mruby-enum-lazy | | Set | stdlib | mruby-set | | ObjectSpace | stdlib | mruby-objectspace | | Time | stdlib-ext | mruby-time | | Struct | stdlib-ext | mruby-struct | | Data | stdlib-ext | mruby-data | | Random | stdlib-ext | mruby-random | | IO, File | stdlib-io | mruby-io | | Socket | stdlib-io | mruby-socket | | Dir | stdlib-io | mruby-dir | | Errno | stdlib-io | mruby-errno | | Math | math | mruby-math | | Rational | math | mruby-rational | | Complex | math | mruby-complex | | Bigint | math | mruby-bigint | | Method, UnboundMethod | metaprog | mruby-method | ### Methods and Features | Feature | Gembox | Gem | | ----------------------------- | ---------- | ------------------ | | `catch`/`throw` | stdlib | mruby-catch | | `Kernel#sprintf`, `String#%` | stdlib-ext | mruby-sprintf | | `Array#pack`, `String#unpack` | stdlib-ext | mruby-pack | | `Kernel#rand` | stdlib-ext | mruby-random | | `Kernel#eval` | metaprog | mruby-eval | | `Kernel#binding` | metaprog | mruby-binding | | `Proc#binding` | metaprog | mruby-proc-binding | | Runtime compiler | metaprog | mruby-compiler | ### Core Class Extensions The `stdlib` gembox also extends built-in classes with additional methods. These are included by default: | Extension | Examples | | ----------------------- | ---------------------------------------------- | | Array extensions | `#dig`, `#union`, `#difference` | | Hash extensions | `#dig`, `#transform_keys`, `#transform_values` | | String extensions | `#encode`, `#bytes`, `#chars` | | Numeric extensions | `Integer#digits`, `Integer#pow` | | Comparable extensions | `#clamp` | | Enumerable extensions | `#sort_by`, `#min_by`, `#max_by`, `#tally` | | Range extensions | `#size`, `#cover?` | | Proc extensions | `#<<`, `#>>` (composition) | | Symbol extensions | `#to_proc` | | Object extensions | `#then`, `#yield_self` | | Kernel extensions | `#__method__` | | Class/Module extensions | `Module#name` | ### Gembox Summary | Gembox | Contents | Notes | | ------------ | --------------------------------------------- | -------------------------------------------- | | `stdlib` | Core class extensions, Fiber, Enumerator, Set | Works with `MRB_NO_STDIO` and `MRB_NO_FLOAT` | | `stdlib-ext` | Time, Struct, Data, Random, sprintf, pack | Works with `MRB_NO_STDIO` and `MRB_NO_FLOAT` | | `stdlib-io` | IO, File, Dir, Socket, Errno | Requires stdio | | `math` | Math, Rational, Complex, Bigint | Works with `MRB_NO_STDIO` | | `metaprog` | eval, binding, Method, compiler | Works with `MRB_NO_STDIO` and `MRB_NO_FLOAT` | | `default` | All of the above + CLI tools | Full installation | ## Key Differences from CRuby ### No Runtime Loading mruby has no `require` or `load`. All code (gems, libraries) is linked at build time. To add functionality, include the appropriate gem in your build configuration: ```ruby MRuby::Build.new do |conf| conf.gem :core => "mruby-time" end ``` ### No `defined?` Keyword The `defined?` keyword raises `NameError` instead of returning a type string or `nil`. Use alternatives: ```ruby # Instead of: defined?(Foo) Object.const_defined?(:Foo) # Instead of: defined?(@var) instance_variable_defined?(:@var) # Instead of: defined?(method_name) respond_to?(:method_name) ``` ### Fiber Limitations Fibers cannot cross C function boundaries. You cannot yield from a fiber inside a C-implemented method. Only `mrb_fiber_yield` at function return is supported. ### Array and String Subclasses `Array` and `String` do not support instance variables to reduce memory. This means subclassing `Array` or `String` and adding `@fields` will raise an error. ### Operator Overriding Operators of primitive classes cannot be overridden by user code. Redefining `String#+` has no effect on the behavior of the `+` operator. ### Module Loading Hooks `include`/`prepend`/`extend` do not call `append_features`/ `prepend_features`/`extend_object` hooks. The module is included directly. ### Small Hash Optimization For small hashes, `#hash` is not called on keys. Custom `#hash` methods may not execute for small hash tables. ### No Refinements Module refinements (`refine`, `using`) are not supported. ### No Encoding Class There is no `Encoding` class. String encoding is either pure bytes or UTF-8 (opt-in via `MRB_UTF8_STRING` compile flag). ### `nil?` in Conditionals Redefining `nil?` has no effect on conditional expressions. The VM uses direct nil checks for performance. ### Integer Precision Integer size varies by boxing mode (see [Numeric Types](#numeric-types) above). Code relying on 64-bit integer precision may behave differently on 32-bit or NaN boxing configurations. ## Build-Time Configuration Key compile-time macros that affect language behavior: | Macro | Effect | | -------------------- | ---------------------------------- | | `MRB_NO_FLOAT` | Remove all float support | | `MRB_USE_FLOAT32` | Use 32-bit float instead of double | | `MRB_UTF8_STRING` | Enable UTF-8 string handling | | `MRB_INT32` | Force 32-bit integer | | `MRB_INT64` | Force 64-bit integer | | `MRB_STR_LENGTH_MAX` | Max string length (default 1MB) | | `MRB_ARY_LENGTH_MAX` | Max array length (default 2^17) | See [mrbconf.md](mrbconf.md) for the complete list of configuration macros. nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/symbol.md0000644000000000000000000000013215232371065021530 xustar0030 mtime=1785328181.913511141 30 atime=1785328183.361518369 30 ctime=1785328203.929140987 nghttp2-1.70.0/third-party/mruby/doc/guides/symbol.md0000644000175100017510000000503115232371065022117 0ustar00runnerrunner # Symbols Symbols in `mruby` C source code is represented by `mrb_sym` which is alias of `uint32_t`. Lower 30 bits are used for symbols so that higher 2 bits can be used as flags, e.g. `struct mt_elem` in `class.c`. ```c struct mt_elem { union mt_ptr ptr; size_t func_p:1; size_t noarg_p:1; mrb_sym key:sizeof(mrb_sym)*8-2; }; ``` ## C API We provide following C API for symbols. ### Generate Symbols #### `mrb_sym mrb_intern(mrb_state*,const char*,size_t)` Get a symbol from a string. #### `mrb_sym mrb_intern_check_cstr(mrb_state*,const char*)` Get a symbol from a NULL terminated (C) string. #### `mrb_sym mrb_intern_str(mrb_state*,mrb_value)` Get a symbol from a Ruby string object. #### `mrb_intern_lit(mrb_state*,const char*)` Get a symbol from a C string literal. The second argument should be a C string literal, otherwise you will get a compilation error. It does not copy C string given the fact it's a literal. #### `mrb_sym mrb_intern_check(mrb_state*,const char*,size_t)` Get a symbol from a string if the string has been already registered as a symbol, otherwise return `0`. We also provide variants `mrb_intern_check_str()` (from Ruby string) and `mrb_intern_check_cstr()` (from C string). #### `const char *mrb_sym_name(mrb_state*,mrb_sym)` Get a string representation of a symbol as a C string. #### `const char *mrb_sym_name_len(mrb_state*,mrb_sym,mrb_int*)` Get a string representation of a symbol, and its length. ## Preallocate Symbols To save RAM, `mruby` can use compile-time allocation of some symbols. You can use following macros to get preallocated symbols by including `mruby/presym.h` header. - `MRB_SYM(xor)` //=> xor (Word characters) - `MRB_SYM_B(xor)` //=> xor! (Method with Bang) - `MRB_SYM_Q(xor)` //=> xor? (Method with Question mark) - `MRB_SYM_E(xor)` //=> xor= (Method with Equal) - `MRB_GVSYM(xor)` //=> $xor (Global Variable) - `MRB_CVSYM(xor)` //=> @@xor (Class Variable) - `MRB_IVSYM(xor)` //=> @xor (Instance Variable) - `MRB_OPSYM(xor)` //=> ^ (Operator) For `MRB_OPSYM()`, specify the names corresponding to operators (see `MRuby::Presym::OPERATORS` in `lib/mruby/presym.rb` for the names that can be specified for it). Other than that, describe only word characters excluding leading and ending punctuation. These macros are converted to static symbol IDs at compile time. The `_2` suffix variants (e.g., `MRB_SYM_2`) are kept for backward compatibility only; they accept an explicit `mrb_state*` parameter but ignore it. New code should use the standard macros above. nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/capi.md0000644000000000000000000000013215232371065021137 xustar0030 mtime=1785328181.912441629 30 atime=1785328183.359518359 30 ctime=1785328203.930504605 nghttp2-1.70.0/third-party/mruby/doc/guides/capi.md0000644000175100017510000006434015232371065021536 0ustar00runnerrunner # C API Reference This document covers the mruby C API for embedding and extending mruby. **Contents:** [Headers](#headers) | [State Management](#state-management) | [Values](#values) | [Defining Classes and Modules](#defining-classes-and-modules) | [Defining Methods](#defining-methods) | [Parsing Arguments](#parsing-arguments) | [Calling Ruby Methods from C](#calling-ruby-methods-from-c) | [String Operations](#string-operations) | [Array Operations](#array-operations) | [Hash Operations](#hash-operations) | [Wrapping C Structures](#wrapping-c-structures) | [Exception Handling](#exception-handling) | [Method Visibility](#method-visibility) | [Proc and Block Handling](#proc-and-block-handling) | [Fiber API](#fiber-api) | [Compilation Contexts](#compilation-contexts) | [Precompiled Bytecode](#precompiled-bytecode) | [GC Arena](#gc-arena) | [Memory Allocation](#memory-allocation) ## Headers ```c #include /* core types, state, class/method definition */ #include /* mrb_load_string, mrb_load_file */ #include /* string operations */ #include /* array operations */ #include /* hash operations */ #include /* wrapping C structs */ #include /* class inspection */ #include /* value type macros */ #include /* loading precompiled bytecode */ #include /* error handling (mrb_protect etc.) */ #include /* instance/class/global variables */ ``` ## State Management ```c mrb_state *mrb = mrb_open(); /* create state with all gems */ mrb_state *mrb = mrb_open_core(); /* create state without gems */ mrb_close(mrb); /* close and free state */ ``` `mrb_open()` returns `NULL` on allocation failure.

Define the data type with a name and destructor */ static void point_free(mrb_state *mrb, void *p) { mrb_free(mrb, p); } static const mrb_data_type point_type = { "Point", point_free }; /* 2. Allocate and initialize */ static mrb_value point_init(mrb_state *mrb, mrb_value self) { mrb_float x, y; mrb_get_args(mrb, "ff", &x, &y); double *data = (double*)mrb_malloc(mrb, sizeof(double) * 2); data[0] = x; data[1] = y; DATA_PTR(self) = data; DATA_TYPE(self) = &point_type; return self; } /* 3. Access the wrapped data */ static mrb_value point_x(mrb_state *mrb, mrb_value self) { double *data = (double*)mrb_data_get_ptr(mrb, self, &point_type); return mrb_float_value(mrb, data[0]); } /* 4. Register the class */ struct RClass *point = mrb_define_class(mrb, "Point", mrb->object_class); MRB_SET_INSTANCE_TT(point, MRB_TT_CDATA); mrb_define_method(mrb, point, "initialize", point_init, MRB_ARGS_REQ(2)); mrb_define_method(mrb, point, "x", point_x, MRB_ARGS_NONE()); ``` ## Exception Handling ### Raising Exceptions ```c mrb_raise(mrb, E_RUNTIME_ERROR, "something went wrong"); mrb_raisef(mrb, E_ARGUMENT_ERROR, "expected %d, got %d", expected, actual); mrb_raise(mrb, E_TYPE_ERROR, "wrong type"); ``` Common exception classes: `E_RUNTIME_ERROR`, `E_TYPE_ERROR`, `E_ARGUMENT_ERROR`, `E_RANGE_ERROR`, `E_NAME_ERROR`, `E_NOMETHOD_ERROR`, `E_NOTIMP_ERROR`, `E_KEY_ERROR`. ### Catching Exceptions ```c /* Check after mrb_load_string or mrb_funcall */ mrb_value result = mrb_load_string(mrb, code); if (mrb->exc) { mrb_print_error(mrb); mrb->exc = NULL; /* clear exception */ } ``` ### Protected Execution `mrb_protect()` executes a function under protection. If an exception is raised, it is captured as a return value instead of propagating: ```c static mrb_value safe_operation(mrb_state *mrb, mrb_value data) { /* This function might raise an exception */ return mrb_funcall(mrb, data, "do_something", 0); } mrb_bool error; mrb_value result = mrb_protect(mrb, safe_operation, data, &error); if (error) { /* result contains the exception object; mrb->exc is cleared */ mrb_value inspect = mrb_inspect(mrb, result); fprintf(stderr, "Error: %s\n", mrb_str_to_cstr(mrb, inspect)); } ``` **Note:** `mrb_protect` clears `mrb->exc` after catching the exception. The exception is returned as `result`. Do not use `mrb_print_error()` after `mrb_protect` — it reads `mrb->exc` which is already `NULL`. For lower-level protection with a `void*` callback: ```c static mrb_value body(mrb_state *mrb, void *userdata) { /* ... */ } mrb_bool error; mrb_value result = mrb_protect_error(mrb, body, userdata, &error); ``` ### Rescue `mrb_rescue()` catches `StandardError` (like Ruby's `rescue`): ```c static mrb_value body_func(mrb_state *mrb, mrb_value body_data) { return mrb_funcall(mrb, body_data, "risky_method", 0); } static mrb_value rescue_func(mrb_state *mrb, mrb_value rescue_data) { /* handle error, rescue_data is the data passed in */ return mrb_nil_value(); } mrb_value result = mrb_rescue(mrb, body_func, body_data, rescue_func, rescue_data); ``` To rescue specific exception classes: ```c struct RClass *classes[] = { E_ARGUMENT_ERROR, mrb_class_get(mrb, "IOError") }; mrb_value result = mrb_rescue_exceptions(mrb, body_func, body_data, rescue_func, rescue_data, 2, classes); ``` ### Ensure `mrb_ensure()` guarantees cleanup runs regardless of exceptions (like Ruby's `ensure`): ```c static mrb_value body_func(mrb_state *mrb, mrb_value data) { return mrb_funcall(mrb, data, "process", 0); } static mrb_value cleanup_func(mrb_state *mrb, mrb_value data) { mrb_funcall(mrb, data, "close", 0); return mrb_nil_value(); } mrb_value result = mrb_ensure(mrb, body_func, body_data, cleanup_func, cleanup_data); ``` The ensure function always executes. If the body raises an exception, the ensure runs and then the exception is re-raised. ### Error State Management ```c mrb_bool mrb_check_error(mrb_state *mrb); /* check and clear mrb->exc */ void mrb_clear_error(mrb_state *mrb); /* clear mrb->exc */ ``` ## Method Visibility ```c /* Public (default) */ mrb_define_method(mrb, klass, "name", func, MRB_ARGS_NONE()); /* Private - only callable without explicit receiver */ mrb_define_private_method(mrb, klass, "name", func, MRB_ARGS_NONE()); /* Class method (singleton method on the class object) */ mrb_define_class_method(mrb, klass, "name", func, MRB_ARGS_NONE()); /* Module function (both module method and private instance method) */ mrb_define_module_function(mrb, mod, "name", func, MRB_ARGS_NONE()); /* Singleton method on a specific object */ mrb_define_singleton_method(mrb, obj, "name", func, MRB_ARGS_NONE()); /* Method alias: alias new_name old_name */ mrb_define_alias(mrb, klass, "new_name", "old_name"); /* Remove a method */ mrb_undef_method(mrb, klass, "name"); mrb_undef_class_method(mrb, klass, "name"); ``` All `_method` variants have `_id` counterparts that accept `mrb_sym` instead of `const char*` for better performance. ## Proc and Block Handling ### Creating Procs from C Functions ```c /* Simple C function proc */ struct RProc *proc = mrb_proc_new_cfunc(mrb, my_func); /* C closure with captured local variables */ struct RProc *proc = mrb_closure_new_cfunc(mrb, my_func, nlocals); ``` ### C Functions with Environment (requires mruby-proc-ext) Store values in a proc's environment, accessible from the C function: ```c mrb_value env_values[] = { mrb_fixnum_value(42) }; struct RProc *proc = mrb_proc_new_cfunc_with_env(mrb, my_func, 1, env_values); /* Inside my_func, retrieve environment values */ static mrb_value my_func(mrb_state *mrb, mrb_value self) { mrb_value val = mrb_proc_cfunc_env_get(mrb, 0); /* index 0 */ return val; } ``` ## Fiber API ```c #include /* fiber types and functions */ ``` ### Creating and Using Fibers ```c /* Create a fiber from a proc */ mrb_value fiber = mrb_fiber_new(mrb, proc); /* Resume the fiber with arguments */ mrb_value args[] = { mrb_fixnum_value(1) }; mrb_value result = mrb_fiber_resume(mrb, fiber, 1, args); /* Check if fiber is still alive */ mrb_bool alive = mrb_test(mrb_fiber_alive_p(mrb, fiber)); ``` ### Yielding from C `mrb_fiber_yield()` can only be used as the return value of a C function — no code may execute after it: ```c static mrb_value my_yield_method(mrb_state *mrb, mrb_value self) { mrb_value yield_args[] = { mrb_str_new_lit(mrb, "yielded") }; return mrb_fiber_yield(mrb, 1, yield_args); /* must be returned directly */ } ``` ### Fiber States | State | Meaning | | ----------------------- | -------------------------------- | | `MRB_FIBER_CREATED` | Created but not yet resumed | | `MRB_FIBER_RUNNING` | Currently executing | | `MRB_FIBER_RESUMED` | Resumed another fiber | | `MRB_FIBER_SUSPENDED` | Yielded, waiting to resume | | `MRB_FIBER_TRANSFERRED` | Transferred via `Fiber#transfer` | | `MRB_FIBER_TERMINATED` | Finished execution | **Limitation:** fibers cannot yield across C function boundaries. You cannot call `mrb_fiber_yield` from within a C-implemented method, except via `mrb_fiber_yield` at function return. ## Compilation Contexts For advanced compilation control, use `mrb_ccontext`: ```c #include mrb_ccontext *cxt = mrb_ccontext_new(mrb); /* Set source filename for error messages and debug info */ mrb_ccontext_filename(mrb, cxt, "my_script.rb"); /* Compile and execute with context */ mrb_value result = mrb_load_string_cxt(mrb, "1 + 2", cxt); /* Clean up */ mrb_ccontext_free(mrb, cxt); ``` ### Context Options The `mrb_ccontext` structure provides several flags: | Field | Purpose | | ---------------- | --------------------------------------- | | `capture_errors` | Collect parse errors instead of raising | | `no_exec` | Compile without executing (get RProc) | | `no_optimize` | Disable peephole optimizations | | `no_ext_ops` | Disable extended operand instructions | | `keep_lv` | Preserve local variables across loads | ### Loading with Context ```c mrb_load_string_cxt(mrb, code, cxt); /* string + context */ mrb_load_nstring_cxt(mrb, code, len, cxt); /* with explicit length */ mrb_load_file_cxt(mrb, fp, cxt); /* file + context */ mrb_load_detect_file_cxt(mrb, fp, cxt); /* auto-detect .mrb or .rb */ ``` ## Precompiled Bytecode Load `.mrb` files compiled by `mrbc`: ```c #include /* From byte array (generated by mrbc -B) */ mrb_value result = mrb_load_irep(mrb, bytecode); /* From buffer with explicit size (safer, bounds-checked) */ mrb_value result = mrb_load_irep_buf(mrb, buf, size); /* From file */ FILE *fp = fopen("script.mrb", "rb"); mrb_value result = mrb_load_irep_file(mrb, fp); fclose(fp); /* Load without executing (returns irep for inspection) */ mrb_irep *irep = mrb_read_irep(mrb, bytecode); ``` All `_irep` loading functions have `_cxt` variants that accept a compilation context. ### Deployment Pattern Ahead-of-time compilation eliminates the need for the compiler gem at runtime: ```shell # Compile to C array mrbc -Bscript_bytecode script.rb # This generates a C header with: # const uint8_t script_bytecode[]; ``` ```c #include "script.mrb.h" mrb_state *mrb = mrb_open_core(); /* no compiler needed */ mrb_load_irep(mrb, script_bytecode); ``` **Important:** wrap bytecode loading in arena save/restore when loading multiple scripts: ```c int ai = mrb_gc_arena_save(mrb); mrb_load_irep(mrb, script1); mrb_gc_arena_restore(mrb, ai); ai = mrb_gc_arena_save(mrb); mrb_load_irep(mrb, script2); mrb_gc_arena_restore(mrb, ai); ``` ## Symbols ```c /* Create symbol from string */ mrb_sym sym = mrb_intern_lit(mrb, "name"); /* from literal */ mrb_sym sym = mrb_intern_cstr(mrb, cstr); /* from C string */ mrb_sym sym = mrb_intern(mrb, ptr, len); /* from pointer + length */ /* Symbol to string */ const char *name = mrb_sym_name(mrb, sym); mrb_int len; const char *name = mrb_sym_name_len(mrb, sym, &len); ``` ## Instance Variables ```c /* Get/set instance variables on an object */ mrb_iv_get(mrb, obj, mrb_intern_lit(mrb, "@x")); mrb_iv_set(mrb, obj, mrb_intern_lit(mrb, "@x"), val); mrb_iv_defined(mrb, obj, mrb_intern_lit(mrb, "@x")); mrb_iv_remove(mrb, obj, mrb_intern_lit(mrb, "@x")); ``` ## Global Variables ```c mrb_gv_get(mrb, mrb_intern_lit(mrb, "$verbose")); mrb_gv_set(mrb, mrb_intern_lit(mrb, "$verbose"), mrb_true_value()); ``` ## Class Variables ```c mrb_cv_get(mrb, klass, mrb_intern_lit(mrb, "@@count")); mrb_cv_set(mrb, klass, mrb_intern_lit(mrb, "@@count"), mrb_fixnum_value(0)); ``` ## Loading and Executing Code ```c /* Load and execute a string (requires mruby-compiler gem) */ mrb_value result = mrb_load_string(mrb, "1 + 2"); /* Load and execute a file */ FILE *f = fopen("script.rb", "r"); mrb_value result = mrb_load_file(mrb, f); fclose(f); /* Load precompiled bytecode (no compiler needed) */ mrb_value result = mrb_load_irep(mrb, bytecode_array); ``` ## GC Arena When creating many temporary Ruby objects in C, use the GC arena to prevent them from being collected prematurely: ```c int ai = mrb_gc_arena_save(mrb); /* create temporary objects here */ mrb_gc_arena_restore(mrb, ai); ``` See [gc-arena-howto.md](gc-arena-howto.md) for details. ## Memory Allocation ```c void *p = mrb_malloc(mrb, size); /* raises on failure */ void *p = mrb_calloc(mrb, nmemb, size); /* zero-initialized */ void *p = mrb_realloc(mrb, ptr, size); /* resize */ mrb_free(mrb, p); /* free */ /* NULL-returning variants (for custom error handling) */ void *p = mrb_malloc_simple(mrb, size); void *p = mrb_realloc_simple(mrb, ptr, size); ``` ## Type Conversion ```c mrb_obj_as_string(mrb, val) /* to_s */ mrb_inspect(mrb, val) /* inspect */ mrb_any_to_s(mrb, val) /* default to_s */ mrb_str_to_integer(mrb, str, base, badcheck) /* String to Integer */ mrb_str_to_dbl(mrb, str, badcheck) /* String to Float */ mrb_ensure_float_type(mrb, val) /* ensure Float */ ``` ## Object Comparison ```c mrb_equal(mrb, a, b) /* Ruby == */ mrb_eql(mrb, a, b) /* Ruby eql? */ mrb_obj_eq(mrb, a, b) /* Ruby equal? (identity) */ mrb_cmp(mrb, a, b) /* Ruby <=> (returns mrb_int) */ ``` ## Object Inspection ```c mrb_obj_classname(mrb, obj) /* class name as C string */ mrb_obj_class(mrb, obj) /* class as RClass* */ mrb_obj_is_kind_of(mrb, obj, klass) /* is_a? / kind_of? */ mrb_obj_respond_to(mrb, klass, mid) /* respond_to? */ mrb_obj_id(obj) /* object_id */ mrb_obj_freeze(mrb, obj) /* freeze */ mrb_obj_dup(mrb, obj) /* dup */ ``` ## Compile-Time Flags When compiling C code that uses mruby, you must use the same flags as the library was built with. Use `mruby-config` to get them: ```console $ build/host/bin/mruby-config --cflags # compiler flags $ build/host/bin/mruby-config --ldflags # linker flags $ build/host/bin/mruby-config --libs # libraries ``` Key macros that affect ABI: | Macro | Effect | | ----------------- | ---------------------------------------- | | `MRB_NO_BOXING` | Struct-based values (larger, debuggable) | | `MRB_WORD_BOXING` | Single-word values (fast, 32-bit safe) | | `MRB_NAN_BOXING` | NaN-tagged values (default on 32-bit) | | `MRB_NO_FLOAT` | Disable Float support | | `MRB_INT64` | 64-bit integers | | `MRB_USE_FLOAT32` | 32-bit floats | Mismatching these between library and application causes silent data corruption. nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/mrbconf.md0000644000000000000000000000013215232371065021651 xustar0030 mtime=1785328181.912511136 30 atime=1785328183.360518364 30 ctime=1785328203.936198948 nghttp2-1.70.0/third-party/mruby/doc/guides/mrbconf.md0000644000175100017510000002056015232371065022244 0ustar00runnerrunner # mruby configuration macros ## The configuration file You can do the build configuration in the build configuration file. The default configuration file is `build_config/default.rb`. You can specify your own configuration file by the `MRUBY_CONFIG` environment variable (you can use `CONFIG` for shorthand for `MRUBY_CONFIG`). If the path doesn't exist, `build_config/${MRUBY_CONFIG}.rb` is used. ## How to use these macros Just add the configuration value to the `MRuby::Build#defines` attribute. This is the same for `MRuby::CrossBuild`. ```ruby # build_config.rb MRuby::Build.new do |conf| ... conf.defines << 'MRB_GC_FIXED_ARENA' conf.defines << 'MRB_NO_METHOD_CACHE' ... end ``` **_NOTE_** - Use common definitions (`conf.defines`) instead of per-compiler definitions (e.g., `conf.cc.defines`) unless there is a special reason not to. - It is now deprecated to edit the `include/mruby/mrbconf.h` file or give it directly as a compiler flag, as was the case before. ## stdio setting `MRB_NO_STDIO` - When defined `` functions won't be used. - Some features will be disabled when this is enabled: - `mrb_irep` load/dump from/to file. - Compiling mruby script from a file. - Printing features in **src/print.c**. ## Debug macros `MRB_USE_DEBUG_HOOK` - When defined code fetch hook and debug OP hook will be enabled. - When using any of the hook set function pointer `code_fetch_hook` and/or `debug_op_hook` of `mrb_state`. - Fetch hook will be called before any OP. - Debug OP hook will be called when dispatching `OP_DEBUG`. `MRB_DEBUG` - When defined `mrb_assert*` macro will be defined with macros from ``. - Could be enabled via `enable_debug` method of `MRuby::Build`. ## Stack configuration `MRB_STACK_EXTEND_DOUBLING` - If defined doubles the stack size when extending it. - Otherwise extends stack with 1.5x growth (minimum `MRB_STACK_GROWTH`). `MRB_STACK_GROWTH` - Default value is `128`. - Minimum stack growth size when extending. - Ignored when `MRB_STACK_EXTEND_DOUBLING` is defined. `MRB_STACK_MAX` - Default value is `0x40000 - MRB_STACK_GROWTH`. - Raises `RuntimeError` when stack size exceeds this value. ## Primitive type configuration `MRB_USE_FLOAT32` - When defined single-precision floating-point type(C type `float`) is used as `mrb_float`. - Otherwise, double-precision floating-point type(C type `double`) is used as `mrb_float`. `MRB_NO_FLOAT` - When defined removes floating-point numbers from mruby. - It makes mruby easier to handle in "Micro-controller without FPU" and "Kernel Space". `MRB_INT32` - When defined, or `MRB_INT64` are not defined on 32-bit CPU mode, `mrb_int` will be defined as `int32_t`. - Conflicts with `MRB_INT64`. `MRB_INT64` - When defined, or `MRB_INT32` are not defined on 64-bit CPU mode, `mrb_int` will be defined as `int64_t`. - Conflicts with `MRB_INT32`. - On 32-bit platforms, `MRB_INT64` requires `MRB_NO_BOXING` because heap-allocated `RInteger` needs 8-byte alignment that the GC heap may not guarantee with word or NaN boxing. ## Garbage collector configuration `MRB_GC_STRESS` - When defined full GC is emitted per each `RBasic` allocation. - Mainly used in memory manager debugging. - If defined at the same time as `MRB_DEBUG`, full GC is emitted also per each heap allocation (`mrb_malloc()` or etc.). This configuration slows down mruby execution by a factor of 2 to 3 or even more. `MRB_GC_TURN_OFF_GENERATIONAL` - When defined turns generational GC off by default. `MRB_GC_FIXED_ARENA` - When defined used fixed size GC arena. - Raises `RuntimeError` when this is defined and GC arena size exceeds `MRB_GC_ARENA_SIZE`. - Useful tracking unnecessary mruby object allocation. `MRB_GC_ARENA_SIZE` - Default value is `100`. - Ignored when `MRB_GC_FIXED_ARENA` isn't defined. - Defines fixed GC arena size. `MRB_HEAP_PAGE_SIZE` - Default value is `1024`. - Specifies number of `RBasic` per each heap page. ## Memory pool configuration `POOL_ALIGNMENT` - Default value is `4`. - If you're allocating data types that requires alignment more than default value define the largest value of required alignment. `POOL_PAGE_SIZE` - Default value is `16000`. - Specifies page size of pool page. - Smaller the value is increases memory overhead. ## State atexit configuration `MRB_FIXED_STATE_ATEXIT_STACK` - If defined enables fixed size `mrb_state` atexit stack. - Raises `RuntimeError` when `mrb_state_atexit` call count to same `mrb_state` exceeds `MRB_FIXED_STATE_ATEXIT_STACK_SIZE`'s value. `MRB_FIXED_STATE_ATEXIT_STACK_SIZE` - Default value is `5`. - If `MRB_FIXED_STATE_ATEXIT_STACK` isn't defined this macro is ignored. ## `mrb_value` configuration `MRB_ENDIAN_BIG` - If defined compiles mruby for big endian machines. - Used in `MRB_NAN_BOXING`. - Some mrbgem use this mrbconf. `MRB_NAN_BOXING` - If defined represent `mrb_value` in boxed `double`. - Conflicts with `MRB_USE_FLOAT32` and `MRB_NO_FLOAT`. `MRB_WORD_BOXING` - If defined represent `mrb_value` as a word (natural unit of data for the processor). - Default boxing mode when none is specified. - On 64-bit platforms, floats are inlined using rotation encoding. - On 32-bit platforms, floats are heap-allocated as `RFloat` objects. `MRB_NO_BOXING` - If defined represent `mrb_value` as a C struct (occupies 2 words). - Most portable but least memory-efficient representation. - Required for `MRB_INT64` on 32-bit platforms. - Default for `host-debug` configuration. `MRB_WORDBOX_NO_INLINE_FLOAT` - If defined disables inline float values in word boxing. - All floats are heap-allocated as `RFloat` objects. - Automatically defined on 32-bit platforms (64-bit `double` cannot fit in a 32-bit word). - Only meaningful with `MRB_WORD_BOXING`. ## Reduce heap memory configuration `MRB_USE_ETEXT_RO_DATA_P` - Use `etext` and `edata` section addresses defined by the linker to detect read-only data. - Those addresses are widely available, but not portable, nor standardized. - Defined by default on User-mode Linux. `MRB_NO_DEFAULT_RO_DATA_P` - Define this macro when the default `mrb_ro_data_p()` does not work for any reason. `MRB_USE_CUSTOM_RO_DATA_P` - Define to provide your own `mrb_ro_data_p()` implementation. - The prototype declaration is `mrb_bool mrb_ro_data_p(const char *ptr)`. - Return `TRUE` if `ptr` is in the read-only section, otherwise return `FALSE`. ## Other configuration `MRB_USE_MALLOC_TRIM` - Call `malloc_trim(0)` for each `mrb_full_gc()` call. `MRB_UTF8_STRING` - Adds UTF-8 encoding support to character-oriented String instance methods. - If it isn't defined, they only support the US-ASCII encoding. `MRB_STR_LENGTH_MAX` - The maximum length of strings (default 1048576). - Set this value to zero to skip the check. `MRB_ARY_LENGTH_MAX` - The maximum length of arrays (default 131072). - Set this value to zero to skip the check. `MRB_FUNCALL_ARGC_MAX` - Default value is `16`. - Specifies 4th argument(`argc`) max value of `mrb_funcall`. - Raises `ArgumentError` when the `argc` argument is bigger then this value `mrb_funcall`. `KHASH_INITIAL_SIZE` - Default value is `32`. - Specifies initial size of khash table bucket. - Used in `kh_init_ ## name` function. `MRB_NO_METHOD_CACHE` - Disable method cache to save memory. `MRB_METHOD_CACHE_SIZE` - Default value is `256`. - Ignored if `MRB_NO_METHOD_CACHE` is defined. - Need to be the power of 2. `MRB_USE_ALL_SYMBOLS` - Make it available `Symbol.all_symbols` in `mrbgems/mruby-symbol-ext` - Increase heap memory usage. `MRB_USE_VM_SWITCH_DISPATCH` - Turn on switch dispatch in VM loop. - Otherwise, computed goto (direct threading) is used when supported by the compiler. `MRB_SYMBOL_LINEAR_THRESHOLD` - Default value is `256`. - Threshold for switching symbol table from linear search to hash table. ## Tuning profiles Predefined profiles adjust several macros together for specific deployment targets. Define one of the following: `MRB_CONSTRAINED_BASELINE_PROFILE` - For micro controllers. - Enables `MRB_NO_METHOD_CACHE`, reduces `KHASH_INITIAL_SIZE` to `16`, and `MRB_HEAP_PAGE_SIZE` to `256`. `MRB_BASELINE_PROFILE` - Default mruby profile.

Provide your own `malloc()`/`realloc()`/`free()` On platforms without a full C standard library —such as many microcontrollers— you may need to supply your own implementations of `malloc()`, `realloc()`, and `free()`. mruby’s allocator calls directly into these functions, so replacing them lets you control **every** allocation and deallocation performed by your entire program, including any third‑party libraries you link against. Keep in mind: - Calling `realloc(NULL, size)` must behave like `malloc(size)`. - Calling `free(NULL)` must be a no‑op. Simply define these three functions in your code (or link against a library that provides them), and mruby — along with all other code in your process — will use your versions automatically. ## 2. Override `mrb_basic_alloc_func()` Inside mruby, all of its own memory allocations go through a single function called mrb_basic_alloc_func() (formerly mrb_default_allocf()). By defining this function in your application before linking, you can intercept and handle **only** the memory operations initiated by mruby itself without affecting other libraries or parts of your program. ```c // Example signature: // void* mrb_basic_alloc_func(void* ptr, size_t size); ``` Implement mrb_basic_alloc_func() in your code, and mruby will invoke it for every internal allocation, reallocation, and free request. ### Expected behavior - `mrb_basic_alloc_func(NULL, size)` should allocate `size` bytes, just like `malloc(size)`. - `mrb_basic_alloc_func(ptr, size)` should resize the existing block at `ptr` to `size` bytes, just like `realloc(ptr, size)`. - `mrb_basic_alloc_func(ptr, 0)` should free the block at `ptr`, just like `free(ptr)`. --- ## Summary of effects: - **Custom `malloc`/`realloc`/`free`**: replaces allocation behavior globally (mruby + all other code and third‑party libraries). - **Custom `mrb_basic_alloc_func()`**: replaces allocation behavior only for mruby’s internal use, leaving other libraries’ allocations untouched. ## Migration note If you are moving from the old API: 1. **Removal of `mrb_open_allocf()`** - \_Old: ```c mrb_state *mrb = mrb_open_allocf(my_allocf, ud); ``` - \_New: ```c // No allocf parameter; set up your hook via mrb_basic_alloc_func definition. mrb_state *mrb = mrb_open_core(); ``` 2. **`mrb_open_core()` takes no arguments** - Simply drop any allocf or user-data arguments, and redefine `mrb_basic_alloc_func` as you need. 3. **No more `mrb_allocf` type** - Definitions using the `mrb_allocf` typedef can be removed; implement `mrb_basic_alloc_func()` with the signature below: ```c void* mrb_basic_alloc_func(void *ptr, size_t size); ``` 4. **`mrb_basic_alloc_func` signature change** - _Old:_ ```c void* mrb_default_allocf(mrb_state *mrb, void *ptr, size_t size, void *ud); ``` - _New:_ ```c void* mrb_basic_alloc_func(void *ptr, size_t size); ``` --- ### Code examples - **Old style**: ```c static void* my_allocf(mrb_state *mrb, void *ud, void *ptr, size_t size) { // ...custom logic... } mrb_state *mrb = mrb_open_allocf(my_allocf, some_ud); ``` - **New style**: ```c // Define your hook before creating the state: void* mrb_basic_alloc_func(void *ptr, size_t size) { // ...custom logic... } mrb_state *mrb = mrb_open_core(); ``` --- ## 3. Heap Regions: Contiguous Memory for GC By default, mruby allocates GC heap pages individually via `malloc()`. On embedded targets with multiple memory banks (e.g., STM32 CCM+SRAM, ESP32 PSRAM+IRAM), you may want to place heap pages in a specific memory region. `mrb_gc_add_region()` lets you provide a contiguous buffer that mruby carves into heap pages. ### API ```c #include int mrb_gc_add_region(mrb_state *mrb, void *start, size_t size); ``` - **`start`**: pointer to a contiguous memory buffer. - **`size`**: size of the buffer in bytes. - **Returns**: number of heap pages carved from the buffer, or 0 if the buffer is too small. The buffer is aligned internally to pointer size. Each page is approximately 40 KB on 64-bit systems (24 KB on 32-bit). The caller retains ownership of the buffer and must keep it valid for the lifetime of the `mrb_state`. ### Example: Static buffer ```c #include #include /* 256 KB static buffer -- about 6 pages on 64-bit */ static char heap_buf[256 * 1024]; int main(void) { mrb_state *mrb = mrb_open(); int pages = mrb_gc_add_region(mrb, heap_buf, sizeof(heap_buf)); /* pages are immediately available for object allocation */ /* ... use mrb ... */ mrb_close(mrb); /* region pages are cleaned up; buffer is not freed */ return 0; } ``` ### Example: MCU with multiple RAM banks ```c /* STM32 with 64 KB CCM and 128 KB SRAM */ extern char __ccm_start[], __ccm_end[]; /* linker symbols */ extern char __sram_start[], __sram_end[]; mrb_state *mrb = mrb_open(); mrb_gc_add_region(mrb, __ccm_start, __ccm_end - __ccm_start); mrb_gc_add_region(mrb, __sram_start, __sram_end - __sram_start); ``` ### How it works When `mrb_gc_add_region()` is called, mruby: 1. Aligns the buffer start to pointer size. 2. Divides the buffer into `mrb_heap_page`-sized chunks. 3. Initializes each page's freelist and links it into the GC heap. 4. Records the region in a descriptor for O(1) pointer-to-page mapping. Region pages participate in the normal GC cycle (mark-and-sweep) like any other heap page. The only differences are: - **Never freed**: the GC will not call `free()` on region pages, even if all objects on a page are dead. The page stays in the heap with an empty freelist, ready for reuse. - **Fallback**: when all region pages are full, mruby falls back to `malloc()` for new pages as usual. - **Cleanup**: `mrb_close()` frees the internal region descriptor but does not free the buffer itself. ### Sizing The page size is controlled by `MRB_HEAP_PAGE_SIZE` (default: 1024 slots). Each page occupies: | Platform | Slot size | Page size (approx) | | -------- | --------- | ------------------ | | 64-bit | 40 bytes | ~41 KB | | 32-bit | 24 bytes | ~25 KB | To estimate pages for a given buffer: `pages = buffer_size / sizeof(mrb_heap_page)`. Each page provides `MRB_HEAP_PAGE_SIZE` object slots. nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/debugger.md0000644000000000000000000000013215232371065022007 xustar0030 mtime=1785328181.912511136 30 atime=1785328183.360518364 30 ctime=1785328203.925060229 nghttp2-1.70.0/third-party/mruby/doc/guides/debugger.md0000644000175100017510000001717215232371065022407 0ustar00runnerrunner # How to Use the mruby Debugger copyright (c) 2014 Specified Non-Profit Corporation mruby Forum ## 1. Summary This file documents the mruby debugger ('mrdb') methods. ## 2 Debugging with mrdb ## 2.1 Building mrdb The trunk of the mruby source tree, with the most recent mrdb, can be checked out with the following command: ```bash $ git clone https://github.com/mruby/mruby.git ``` To run the `make` command: ```bash $ cd mruby $ make ``` By default, the `make` command will install the debugger files into mruby/bin. You can add the path for mrdb on your host environment with the following command: ```bash $ echo "export PATH=\$PATH:MRUBY_ROOT/bin" >> ~/.bashrc $ source ~/.bashrc ``` `*MRUBY_ROOT` is the directory in which mruby source code will be installed. To confirm mrdb was installed properly, run mrdb with the `--version` option: ```bash $ mrdb --version mruby 4.0.0 (2026-04-20) ``` ## 2.2 Basic Operation ### 2.2.1 Debugging mruby Script Files (rb file) with mrdb To invoke the mruby debugger, just type `mrdb`. To specify the script file: ```bash $ mrdb [option] filename ``` For example: Debugging sample.rb ```bash $ mrdb sample.rb ``` You can execute the shell commands listed below: | command | description | | :--------------: | :------------------------------------------------------------------------ | | run | execute programs | | step | execute stepping | | continue | execute continuing program | | break | configure the breaking point | | delete | deleting the breaking points | | disable | disabling the breaking points | | enable | enabling the breaking points | | info breakpoints | showing list of the breaking points | | print | evaluating and printing the values of the mruby expressions in the script | | list | displaying the source cords | | help | showing help | | quit | terminating the mruby debugger | ### 2.2.2 Debugging mruby Binary Files (mrb file) with mrdb You can debug the mruby binary files. #### 2.2.2.1 Debugging the binary files - notice To debug mruby binary files, you need to compile mruby files with option `-g`. ```bash $ mrbc -g sample.rb ``` You can debug the mruby binary files with following command and the option `-b`. ```bash $ mrdb -b sample.mrb ``` Then you can execute all debugger shell commands. #### Break Command You can use any breakpoint to stop the program by specifying the line number and method name. The breakpoint list will be displayed after you have set the breakpoint successfully. Usage: ``` break [file:]linenum b [file:]linenum break [class:]method b [class:]method ``` The breakpoint will be ordered in serial from 1. The number, which was given to the deleted breakpoint, will never be given to another breakpoint again. You can give multiple breakpoints to the specified the line number and method. Be aware that the breakpoint command will not check the validity of the class name and method name. You can get the current breakpoint information by the following options. breakpoint breakpoint number : filename. line number breakpoint breakpoint number : [class name,] method name #### Continue Command Usage: ``` continue [N] c [N] ``` N: the next breakpoint number When resuming the program, it will stop at breakpoint N (N-1 breakpoint will be ignored). When you run the `continue` command without specifying N, the program will be stopped at the next breakpoint. Example: ``` (foo.rb:1) continue 3 ``` This will resume the program and stop it at the third breakpoint. #### Delete Command This will delete the specified breakpoint. Usage: ``` delete [breakpoint-no] d [breakpoint-no] ``` breakpoint-no: breakpoint number Example: ``` (foo.rb:1) delete ``` This will delete all the breakpoints. ``` (foo.rb:1) delete 1 3 ``` This will delete the breakpoint at 1 and 3. #### Disable Command This will disable the specified breakpoint. Usage: ``` disable [breakpoint-no] dis [breakpoint-no] ``` reappointing: breakpoint number Example: ``` (foo.rb:1) disable ``` Use `disable` if you would like to disable all the breakpoints. ``` (foo.rb:1) disable 1 3 ``` This will disable the breakpoints at 1 and 3. #### Enable Command This will enable the specified breakpoints. Usage: ``` enable [breakpoint-no] e [breakpoint-no] ``` breakpoint-no: breakpoint number Example: ``` (foo.rb:1) enable ``` Enabling all breakpoints ``` (foo.rb:1) enable 1 3 ``` Enabling the breakpoint 1 and 3 #### eval command Evaluating the string as source code and printing the value. Same as print command, please see print command. #### help command Displaying the help message. Usage: ``` help [command] h [command] ``` Typing `help` without any options will display the command list. #### Info Breakpoints Command Displaying the specified breakpoint information. Usage: ``` info breakpoints [breakpoint-no] i b [breakpoint-no] ``` breakpoint-no: breakpoint number Typing "info breakpoints" without ant option will display all breakpoint information. Example: ``` (sample.rb:1) info breakpoints Num Type Enb What 1 breakpoint y at sample.rb:3 -> filename,line number 2 breakpoint n in Sample_class:sample_class_method -> [class:]method name 3 breakpoint y in sample_global_method ``` Displaying the specified breakpoint number: ``` (foo.rb:1) info breakpoints 1 3 Num Type Enb What 1 breakpoint y at sample.rb:3 3 breakpoint y in sample_global_method ``` #### List Command To display the code of the source file. Usage: ``` list [filename:]first[,last] l [filename]:first[,last] ``` first: the opening row number last : the closing row number When you specify the `first`, but not the `last` option, you will receive 10 rows. When you do not specify both the `first` and `last` options, you will receive the next 10 rows. Example: ``` Specifying filename and first row number sample.rb:1) list sample2.rb:5 ``` Specifying the filename and the first and last row number: ``` (sample.rb:1) list sample2.rb:6,7 ``` #### Print Command Evaluating the string as source code and printing the value. Usage: ``` print [expr] p [expr] ``` expr: expression The expression is mandatory. The displayed expressions will be serially ordered from 1. If an exception occurs, the exception information will be displayed, and the debugging will be continued. Example: ``` (sample.rb:1) print 1+2 $1 = 3 (sample.rb:1) print self $2 = main ``` Below is the case of the exception: ``` (sample.rb:1) print (1+2 $1 = SyntaxError: line 1: syntax error, unexpected $end, expecting ')' ``` #### Quit Command Quitting the debugger. Usage: ``` quit q ``` #### Run Command Running the program and stopping at the first breakpoint. Usage: ``` run r ``` #### Step Command This will run the program step by step. When the method and the block are invoked, the program will stop at the first row. The program, which is developed in C, will be ignored. nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/gc-arena-howto.md0000644000000000000000000000013215232371065023036 xustar0030 mtime=1785328181.912511136 30 atime=1785328183.360518364 30 ctime=1785328203.934841289 nghttp2-1.70.0/third-party/mruby/doc/guides/gc-arena-howto.md0000644000175100017510000001417615232371065023437 0ustar00runnerrunner # How to use `mrb_gc_arena_save()`/`mrb_gc_arena_restore()`/`mrb_gc_protect()` _This is an English translation of [Matz's blog post][matz blog post] written in Japanese._ _Some parts are updated to reflect recent changes._ [matz blog post]: https://www.rubyist.net/~matz/20130731.html When you are extending mruby using C language, you may encounter mysterious "arena overflow error" or memory leak or very slow execution speed. This is an error indicating overflow of "GC arena" implementing "conservative GC". GC (garbage collector) must ensure that object is "alive", in other words, that it is referenced by somewhere from the program. This can be determined by checking if the object can be directly or indirectly referenced by root. The local variables, global variables and constants etc. are root. If program execution is performed inside mruby VM, there is nothing to worry about because GC can access all roots owned by the VM. The problem arises when executing C functions. The object referenced by C variable is also "alive", but mruby GC cannot aware of this, so it might mistakenly recognize the objects referenced by only C variables as dead. This can be a fatal bug if the GC tries to collect a live object. In CRuby, we scan C stack area, and use C variable as root to check whether object is alive or not. Of course, because we are accessing C stack just as memory region, we never know it is an integer or a pointer. We work around this by assuming that if it looks like a pointer, then assume it as a pointer. We call it "conservative". By the way, CRuby's "conservative GC" has some problems. The biggest problem is we have no way to access to the stack area in portable way. Therefore, we cannot use this method if we'd like to implement highly portable runtime, like mruby. So we came up with another plan to implement "conservative GC" in mruby. Again, the problem is when an object which was created in C function, becomes no longer referenced in the Ruby world, and cannot be treated as garbage. In mruby, we recognize all objects created in C function are alive. Then we have no problem such as confusing a live object as dead. This means that because we cannot collect a truly dead object, we may lose efficiency, but as a trade-off the GC itself is highly portable. We can say goodbye to the problem that GC deletes live objects due to optimization which sometimes occurs in CRuby. According to this idea, we have a table, called "GC arena", which remembers objects created in C function. The arena is stack structure, when C function execution is returned to mruby VM, all objects registered in the arena are popped. This works very well, but can cause another problem: "arena overflow error" or memory leak. As of this writing, mruby automatically extend arena to remember objects (See `MRB_GC_FIXED_ARENA` and `MRB_GC_ARENA_SIZE` in [doc/guides/mrbconf.md](mrbconf.md)). If you create many objects in C functions, memory usage will increase, since GC never kicks in. This memory usage may look like memory leaks, but will also make execution slower as more memory will need to be allocated. With the build time configuration, you can limit the maximum size of arena (e.g., 100). Then if you create many objects, arena overflows, thus you will get an "arena overflow error". To work around these problems, we have `mrb_gc_arena_save()` and `mrb_gc_arena_restore()` functions. `int mrb_gc_arena_save(mrb)` returns the current position of the stack top of GC arena, and `void mrb_gc_arena_restore(mrb, idx)` sets the stack top position to back to given `idx`. We can use them like this: ```c int arena_idx = mrb_gc_arena_save(mrb); // ...create objects... mrb_gc_arena_restore(mrb, arena_idx); ``` In mruby, C function calls are surrounded by this save/restore, but we can further optimize memory usage by surrounding save/restore, and can avoid creating arena overflow bugs. Let's take a real example. Here is the source code of `Array#inspect` (from `src/array.c`): ```c static mrb_value mrb_ary_to_s(mrb_state *mrb, mrb_value self) { mrb->c->ci->mid = MRB_SYM(inspect); mrb_value ret = mrb_str_new_lit(mrb, "["); int ai = mrb_gc_arena_save(mrb); if (MRB_RECURSIVE_UNARY_P(mrb, MRB_SYM(inspect), self)) { mrb_str_cat_lit(mrb, ret, "...]"); return ret; } for (mrb_int i=0; i0) mrb_str_cat_lit(mrb, ret, ", "); mrb_str_cat_str(mrb, ret, mrb_inspect(mrb, RARRAY_PTR(self)[i])); mrb_gc_arena_restore(mrb, ai); } mrb_str_cat_lit(mrb, ret, "]"); return ret; } ``` The essence of `Array#inspect` is that after stringifying each element of array using `inspect` method, we join them together so that we can get `inspect` representation of the entire array. After the `inspect` representation is created, we no longer require the individual string representation. This means that we don't have to register these temporal objects into GC arena. Therefore, in order to keep the arena size small; the function will do the following: - save the position of the stack top using `mrb_gc_arena_save()`. - get `inspect` representation of each element. - append it to the constructing entire `inspect` representation of array. - restore stack top position using `mrb_gc_arena_restore()`. Please note that the final `inspect` representation of entire array was created before the call of `mrb_gc_arena_restore()`. Otherwise, required temporal object may be deleted by GC. We may have an usecase where after creating many temporal objects, we'd like to keep some of them. In this case, we cannot use the same idea in `mrb_ary_to_s()` like appending objects to existing one. Instead, after `mrb_gc_arena_restore()`, we must re-register the objects we want to keep in the arena using `mrb_gc_protect(mrb, obj)`. Use `mrb_gc_protect()` with caution because it could also lead to an "arena overflow error". We must also mention that when `mrb_funcall` is called in top level, the return value is also registered to GC arena, so repeated use of `mrb_funcall` may eventually lead to an "arena overflow error". Use `mrb_gc_arena_save()` and `mrb_gc_arena_restore()` or possible use of `mrb_gc_protect()` to workaround this. nghttp2-1.70.0/third-party/mruby/doc/guides/PaxHeaders/getting-started.md0000644000000000000000000000013215232371065023330 xustar0030 mtime=1785328181.912511136 30 atime=1785328183.360518364 30 ctime=1785328203.933282567 nghttp2-1.70.0/third-party/mruby/doc/guides/getting-started.md0000644000175100017510000001350015232371065023717 0ustar00runnerrunner # Getting Started with mruby This guide walks you through building mruby, running your first Ruby program, and embedding mruby in a C application. ## Prerequisites You need: - C compiler (`gcc` or `clang`) - Ruby 2.5 or later (for the build system) - `rake` (bundled with Ruby) - `git` (optional, for cloning the source) ## Building mruby Clone the repository and build: ```console $ git clone https://github.com/mruby/mruby.git $ cd mruby $ rake ``` This compiles the default configuration and produces: - `bin/mruby` — Ruby script interpreter - `bin/mirb` — interactive Ruby shell - `bin/mrbc` — bytecode compiler - `build/host/lib/libmruby.a` — library for embedding ## Running Ruby Code ### Interactive shell ```console $ bin/mirb mirb - Pair interactive mruby > puts "Hello, mruby!" Hello, mruby! => nil > 1 + 2 => 3 ``` ### Running a script file Create `hello.rb`: ```ruby puts "Hello from mruby!" ``` Run it: ```console $ bin/mruby hello.rb Hello from mruby! ``` ### One-liner ```console $ bin/mruby -e 'puts "Hello!"' Hello! ``` ## Compiling to Bytecode mruby can compile Ruby scripts to bytecode (`.mrb` files) for faster loading and deployment without source code: ```console $ bin/mrbc hello.rb # produces hello.mrb $ bin/mruby -b hello.mrb # run bytecode Hello from mruby! ``` You can also generate C source from Ruby scripts: ```console $ bin/mrbc -Bhello_code hello.rb # produces hello.c with byte array ``` This generates a C file with a `const uint8_t hello_code[]` array that can be loaded with `mrb_load_irep()` in your C application. ## Embedding mruby in C The primary use case of mruby is embedding in C/C++ applications. ### Minimal example Create `embed.c`: ```c #include #include int main(void) { mrb_state *mrb = mrb_open(); if (!mrb) return 1; mrb_load_string(mrb, "puts 'Hello from embedded mruby!'"); if (mrb->exc) { mrb_print_error(mrb); } mrb_close(mrb); return 0; } ``` ### Compile and link Use `mruby-config` to get the correct compiler and linker flags: ```console $ gcc -I include `build/host/bin/mruby-config --cflags` embed.c \ `build/host/bin/mruby-config --ldflags --libs` -o embed $ ./embed Hello from embedded mruby! ``` **Important**: Always use `mruby-config --cflags` when compiling code that uses mruby. The build configuration may define macros (such as `MRB_NO_BOXING` or `MRB_USE_BIGINT`) that change the internal data layout. Compiling without these flags causes silent data corruption. ### Calling Ruby from C ```c #include #include #include #include int main(void) { mrb_state *mrb = mrb_open(); /* Define a Ruby method */ mrb_load_string(mrb, "def greet(name) \"Hello, #{name}!\" end"); /* Call it from C */ mrb_value result = mrb_funcall(mrb, mrb_top_self(mrb), "greet", 1, mrb_str_new_lit(mrb, "World")); printf("%s\n", mrb_str_to_cstr(mrb, result)); mrb_close(mrb); return 0; } ``` ### Defining C functions callable from Ruby ```c #include #include static mrb_value my_add(mrb_state *mrb, mrb_value self) { mrb_int a, b; mrb_get_args(mrb, "ii", &a, &b); return mrb_fixnum_value(a + b); } int main(void) { mrb_state *mrb = mrb_open(); /* Define method on Kernel (available everywhere) */ mrb_define_method(mrb, mrb->kernel_module, "my_add", my_add, MRB_ARGS_REQ(2)); mrb_load_string(mrb, "puts my_add(3, 4)"); /* prints 7 */ mrb_close(mrb); return 0; } ``` ## Loading Precompiled Bytecode For deployment without the compiler gem, precompile your Ruby code: ```console $ bin/mrbc -Bruby_code app.rb ``` Then load in C: ```c #include #include #include "app.c" /* contains ruby_code[] */ int main(void) { mrb_state *mrb = mrb_open(); mrb_load_irep(mrb, ruby_code); if (mrb->exc) { mrb_print_error(mrb); } mrb_close(mrb); return 0; } ``` This approach does not require the `mruby-compiler` gem, resulting in a smaller binary. ## Customizing the Build mruby's functionality is controlled by the build configuration file. The default is `build_config/default.rb`. ### Using a custom configuration ```console $ MRUBY_CONFIG=build_config/minimal.rb rake ``` ### Selecting gems Gems add features to mruby. A minimal configuration: ```ruby MRuby::Build.new do |conf| conf.toolchain :gcc # Core language extensions conf.gem core: 'mruby-array-ext' conf.gem core: 'mruby-string-ext' conf.gem core: 'mruby-hash-ext' # Tools conf.gem core: 'mruby-bin-mruby' # mruby command conf.gem core: 'mruby-bin-mirb' # interactive shell conf.gem core: 'mruby-bin-mrbc' # bytecode compiler # Compiler (needed for mrb_load_string) conf.gem core: 'mruby-compiler' end ``` ### Using a gembox Gemboxes are predefined collections of gems: ```ruby MRuby::Build.new do |conf| conf.toolchain :gcc conf.gembox 'default' # standard set of gems end ``` ## Amalgamation (Single-File Build) For the simplest integration, use amalgamation to combine all mruby source into a single `mruby.c` and `mruby.h`: ```console $ rake amalgam $ gcc -I build/host/amalgam your_app.c build/host/amalgam/mruby.c -o your_app -lm ``` See [amalgamation.md](amalgamation.md) for details. ## What's Next -

For examples: - `default`: the default configuration - `host-gprof`: compiles with `gprof` for performance tuning - `host-m32`: compiles in gcc 32-bit mode on 64-bit platforms - `boxing`: compiles all three boxing options - `clang-asan`: compiles with `clang`'s Address Sanitizer You can specify the build configuration file with the `MRUBY_CONFIG` environment variable (or `CONFIG` in short). If the value specified by `MRUBY_CONFIG` is not the path to the configuration file, `build_config/${MRUBY_CONFIG}.rb` is used. So you can specify it as `rake MRUBY_CONFIG=boxing`, for example. # Build Configuration Contribution When you write a new build configuration description, please contribute. We welcome your contribution as a GitHub pull-request. # Language Changes ## New Syntax We have ported some new syntax from CRuby. - Single line pattern matching (`12 => x`); mruby matches only with local variables at the moment - Numbered block parameter (`x.map{_1 * 2}`) - End-less `def` (`def double(x) = x*2`) # Configuration Options Changed ## Renamed for consistency Some configuration macro names are changed for consistency (use `MRB_USE_XXX` or `MRB_NO_XXX`). | mruby2 | mruby3 | | ------------------------------ | ------------------------- | | `MRB_ENABLE_ALL_SYMBOLS` | `MRB_USE_ALL_SYMBOLS` | | `MRB_ENABLE_CXX_ABI` | `MRB_USE_CXX_ABI` | | `MRB_ENABLE_CXX_EXCEPTION` | `MRB_USE_CXX_EXCEPTION` | | `MRB_ENABLE_DEBUG_HOOK` | `MRB_USE_DEBUG_HOOK` | | `MRB_DISABLE_DIRECT_THREADING` | `MRB_NO_DIRECT_THREADING` | | `MRB_DISABLE_STDIO` | `MRB_NO_STDIO` | | `MRB_METHOD_T_STRUCT` | `MRB_USE_METHOD_T_STRUCT` | | `MRB_USE_FLOAT` | `MRB_USE_FLOAT32` | | `MRB_WITHOUT_FLOAT` | `MRB_NO_FLOAT` | | `ENABLE_LINENOISE` | `MRB_USE_LINENOISE` | | `ENABLE_READLINE` | `MRB_USE_READLINE` | | `DISABLE_MIRB_UNDERSCORE` | `MRB_NO_MIRB_UNDERSCORE` | - `MRB_USE_FLOAT32` is changed from `MRB_USE_FLOAT` to make sure `float` here means using single-precision float, and not the opposite of `MRB_NO_FLOAT`. - `MRB_USE_METHOD_T_STRUCT` uses `struct` version of `mrb_method_t`. More portable but consumes more memory. Turned on by default on 32-bit platforms. - `MRB_` prefix is added to those without. ## `MRB_NO_BOXING` Uses `struct` to represent `mrb_value`. Consumes more memory but easier to investigate the internal and to debug. It used to be default `mrb_value` representation. Now the default is `MRB_WORD_BOXING`. ## `MRB_WORD_BOXING` Pack `mrb_value` in an `intptr_t` integer. Consumes less memory compared to `MRB_NO_BOXING` especially on 32-bit platforms. `Fixnum` size is 31 bits so some integer values does not fit in `Fixnum` integers. ## `MRB_NAN_BOXING` Pack `mrb_value` in a floating-point number. Nothing changed from previous versions. ## `MRB_USE_MALLOC_TRIM` Call `malloc_trim(0)` from mrb_full_gc() if this macro is defined. If you are using glibc malloc, this macro could reduce memory consumption. # Command Line Program ## `bin/mruby` (by mrbgems/mruby-bin-mruby) The mruby3 now automatically detects `*.mrb` files without the `-b` switch. Therefore, it can be mixed with the `*.rb` file in combination with the `-r` switch and specified at the same time. Here's an example that works fine: ```console $ bin/mruby app.mrb $ bin/mruby -r lib1.mrb -r lib2.rb app.rb $ bin/mruby -r lib1.rb -r lib2.rb < app.mrb ``` # Internal Changes ## New Instructions `mruby3` introduces a few new instructions. Instructions that access pool[i]/syms[i] where i>255. - `OP_LOADL16` - `OP_STRING16` - `OP_LOADSYM16` Instructions that load a 32-bit integer. - `OP_LOADI32` Instruction that unwinds jump table for rescue/ensure. - `OP_JMPUW` Renamed from `OP_RAISE` - `OP_RAISEIF` Instruction that is reserved for the future keyword argument support. - OP_SENDVK ## Removed Instructions Instructions for old exception handling - `OP_ONERR` - `OP_POPERR` - `OP_EPUSH` - `OP_EPOP` No more operand extension - `OP_EXT1` - `OP_EXT2` - `OP_EXT3` ## Changed Instructions Jump addresses used to be specified by absolute offset from the start of `iseq`. Now they are relative offset from the address of the next instruction. ## `Random` now use `xoshiro128++`.
