Free Software Foundation, Inc. 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. '--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. '--no-create' '-n' Run the configure checks, but stop before creating any output files. 'configure' also accepts some other, not widely useful, options. Run 'configure --help' for more details. nghttp2-1.69.0/PaxHeaders/android-env0000644000000000000000000000013115171116653014411 xustar0029 mtime=1776590251.59722281 30 atime=1776590256.533313821 30 ctime=1776590280.043806103 nghttp2-1.69.0/android-env0000755000175100017510000000305715171116653015012 0ustar00runnerrunner#!/bin/sh # # nghttp2 - HTTP/2 C Library # # Copyright (c) 2022 nghttp2 contributors # # Permission is hereby granted, free of charge, to any person obtaining # a copy of this software and associated documentation files (the # "Software"), to deal in the Software without restriction, including # without limitation the rights to use, copy, modify, merge, publish, # distribute, sublicense, and/or sell copies of the Software, and to # permit persons to whom the Software is furnished to do so, subject to # the following conditions: # # The above copyright notice and this permission notice shall be # included in all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, # EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF # MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND # NONINFRINGEMENT.

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.

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).

Options: The options are categorized into several groups. Connections: -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, -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". 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.

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.

The request method is changed to POST. For http/1.1 connection, if -d is used, the maximum number of in-flight pipelined requests is set to 1. -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 -c option. This rate will be distributed among threads as evenly as possible. For example, with -t2 and -r4, 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. -r and -D are mutually exclusive. --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. -D, --duration= Specifies the main duration for the measurements in case of timing-based benchmarking. -D and -r are mutually exclusive. --warm-up-time= Specifies the time period before starting the actual measurements, in case of timing-based benchmarking. Needs to provided along with -D 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. -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. --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 -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 -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. --timing-script-file and --rps are mutually exclusive. -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. --alpn-list= Comma delimited list of ALPN protocol identifier sorted in the order of preference.

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. --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").

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 664a985707470a62f436cca862ccec9524c561ca); or OpenSSL >= 3.5.0 * `ngtcp2 `_ >= 1.16.0 * `nghttp3 `_ >= 1.12.0 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++20 compliant compiler is required. At least g++ >= 12 and clang++ >= 18 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.

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.

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.

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.

By submitting a patch to the nghttp2 project, you (or your employer, as the case may be) agree to assign the copyright of your submission to us. .. the above really needs to be reworded to pass legal muster. 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! See `Contribution Guidelines `_ for more details. Versioning ---------- In general, we follow `Semantic Versioning `_. We may release PATCH releases between the regular releases, mainly for severe security bug fixes. We have no plan to break API compatibility changes involving soname bump, so MAJOR version will stay 1 for the foreseeable future.

VERSION may be '11', '14', '17', or '20' for # the respective C++ standard version. # # The second argument, if specified, indicates whether you insist on an # extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. # -std=c++11). If neither is specified, you get whatever works, with # preference for no added switch, and then for an extended mode. # # The third argument, if specified 'mandatory' or if left unspecified, # indicates that baseline support for the specified C++ standard is # required and that the macro should error out if no mode with that # support is found. If specified 'optional', then configuration proceeds # regardless, after defining HAVE_CXX${VERSION} if and only if a # supporting mode is found. # # LICENSE # # Copyright (c) 2008 Benjamin Kosnik # Copyright (c) 2012 Zack Weinberg # Copyright (c) 2013 Roy Stogner # Copyright (c) 2014, 2015 Google Inc.; contributed by Alexey Sokolov # Copyright (c) 2015 Paul Norman # Copyright (c) 2015 Moritz Klammler # Copyright (c) 2016, 2018 Krzesimir Nowak # Copyright (c) 2019 Enji Cooper # Copyright (c) 2020 Jason Merrill # Copyright (c) 2021 Jörn Heusipp # # 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.

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. 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. This function is low-level in a sense that the application code can specify flags directly. For usual HTTP request, `nghttp2_submit_request2()` is useful. Likewise, for HTTP response, prefer `nghttp2_submit_response2()`. This function returns newly assigned stream ID if it succeeds and *stream_id* is -1. Otherwise, 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_STREAM_ID_NOT_AVAILABLE` No stream ID is available because maximum stream ID was reached. :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. This happens if stream denoted by *stream_id* is in reserved state. :enum:`nghttp2_error.NGHTTP2_ERR_PROTO` The *stream_id* is -1, and *session* is server session. .. warning:: This function returns assigned stream ID if it succeeds and *stream_id* is -1. But that stream is not opened yet. The application must not submit frame to that stream ID before :type:`nghttp2_before_frame_send_callback` is called for this frame. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_option_set_builtin_recv_extension_type.rst0000644000000000000000000000013215171116706025312 xustar0030 mtime=1776590278.586011739 30 atime=1776590278.693731599 30 ctime=1776590281.859607193 nghttp2-1.69.0/doc/nghttp2_option_set_builtin_recv_extension_type.rst0000644000175100017510000000156115171116706025705 0ustar00runnerrunner nghttp2_option_set_builtin_recv_extension_type ============================================== Synopsis -------- *#include * .. function:: void nghttp2_option_set_builtin_recv_extension_type(nghttp2_option *option, uint8_t type) Sets extension frame type the application is willing to receive using builtin handler.

This only affects client side, since only server can push streams. Malicious server can push arbitrary number of streams, and make client's memory exhausted. This option can set the maximum number of such incoming streams to avoid possible memory exhaustion. If this option is set, and pushed streams are automatically closed on reception, without calling user provided callback, if they exceed the given limit. The default value is 200. If session is configured as server side, this option has no effect. Server can control the number of streams to push. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_hd_inflate_new.rst0000644000000000000000000000013215171116706020173 xustar0030 mtime=1776590278.585743396 30 atime=1776590278.684731433 30 ctime=1776590281.849885294 nghttp2-1.69.0/doc/nghttp2_hd_inflate_new.rst0000644000175100017510000000075015171116706020565 0ustar00runnerrunner nghttp2_hd_inflate_new ====================== Synopsis -------- *#include * .. function:: int nghttp2_hd_inflate_new(nghttp2_hd_inflater **inflater_ptr) Initializes *\*inflater_ptr* for inflating name/values pairs.

This function behaves like `nghttp2_session_terminate_session()`, but the last stream ID can be specified by the application for fine grained control of stream. The HTTP/2 specification does not allow last_stream_id to be increased. So the actual value sent as last_stream_id is the minimum value between the given *last_stream_id* and the last_stream_id we have previously sent to the peer. 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. 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 *last_stream_id* is invalid. nghttp2-1.69.0/doc/PaxHeaders/tutorial-hpack.rst.in0000644000000000000000000000013215171116653017114 xustar0030 mtime=1776590251.603722839 30 atime=1776590256.535313858 30 ctime=1776590281.792144927 nghttp2-1.69.0/doc/tutorial-hpack.rst.in0000644000175100017510000000020315171116653017477 0ustar00runnerrunner.. include:: @top_srcdir@/doc/sources/tutorial-hpack.rst deflate.c --------- .. literalinclude:: @top_srcdir@/examples/deflate.c nghttp2-1.69.0/doc/PaxHeaders/nghttp2_session_set_local_window_size.rst0000644000000000000000000000013215171116706023356 xustar0030 mtime=1776590278.590333099 30 atime=1776590278.834734204 30 ctime=1776590282.001347146 nghttp2-1.69.0/doc/nghttp2_session_set_local_window_size.rst0000644000175100017510000000342015171116706023745 0ustar00runnerrunner nghttp2_session_set_local_window_size ===================================== Synopsis -------- *#include * .. function:: int nghttp2_session_set_local_window_size(nghttp2_session *session, uint8_t flags, int32_t stream_id, int32_t window_size) Set local window size (local endpoints's window size) to the given *window_size* for the given stream denoted by *stream_id*. 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. :enum:`nghttp2_error.NGHTTP2_ERR_NOMEM` Out of memory. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_session_callbacks_set_send_callback2.rst0000644000000000000000000000013115171116706024470 xustar0030 mtime=1776590278.588396415 29 atime=1776590278.77173304 30 ctime=1776590281.937791519 nghttp2-1.69.0/doc/nghttp2_session_callbacks_set_send_callback2.rst0000644000175100017510000000077515171116706025072 0ustar00runnerrunner nghttp2_session_callbacks_set_send_callback2 ============================================ Synopsis -------- *#include * .. function:: void nghttp2_session_callbacks_set_send_callback2( nghttp2_session_callbacks *cbs, nghttp2_send_callback2 send_callback) Sets callback function invoked when a session wants to send data to the remote peer.

In most cases, this will simplify the implementation of server. But sometimes server may want to detect the application protocol based on first few bytes on clear text communication. If this option is used with nonzero *val*, nghttp2 library does not handle MAGIC. It still checks following SETTINGS frame. This means that applications should deal with MAGIC by themselves. If this option is not used or used with zero value, if MAGIC does not match :macro:`NGHTTP2_CLIENT_MAGIC`, `nghttp2_session_recv()` and `nghttp2_session_mem_recv2()` will return error :enum:`nghttp2_error.NGHTTP2_ERR_BAD_CLIENT_MAGIC`, which is fatal error. nghttp2-1.69.0/doc/PaxHeaders/conf.py.in0000644000000000000000000000013115171116653014731 xustar0030 mtime=1776590251.601021949 29 atime=1776590256.53431384 30 ctime=1776590281.780272463 nghttp2-1.69.0/doc/conf.py.in0000644000175100017510000002117215171116653015325 0ustar00runnerrunner# -*- coding: utf-8 -*- # nghttp2 - HTTP/2 C Library # Copyright (c) 2012 Tatsuhiro Tsujikawa # Permission is hereby granted, free of charge, to any person obtaining # a copy of this software and associated documentation files (the # "Software"), to deal in the Software without restriction, including # without limitation the rights to use, copy, modify, merge, publish, # distribute, sublicense, and/or sell copies of the Software, and to # permit persons to whom the Software is furnished to do so, subject to # the following conditions: # The above copyright notice and this permission notice shall be # included in all copies or substantial portions of the Software. # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, # EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF # MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND # NONINFRINGEMENT.

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.

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 have END_STREAM set. The *stream_user_data* is data associated to the stream opened by this request and can be an arbitrary pointer, which can be retrieved later by `nghttp2_session_get_stream_user_data()`. This function returns assigned stream ID 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_STREAM_ID_NOT_AVAILABLE` No stream ID is available because maximum stream ID was reached. :enum:`nghttp2_error.NGHTTP2_ERR_PROTO` The *session* is server session. .. warning:: This function returns assigned stream ID if it succeeds. But that stream is not created yet. The application must not submit frame to that stream ID before :type:`nghttp2_before_frame_send_callback` is called for this frame. This means `nghttp2_session_get_stream_user_data()` does not work before the callback. But `nghttp2_session_set_stream_user_data()` handles this situation specially, and it can set data to a stream during this period. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_session_check_request_allowed.rst0000644000000000000000000000013115171116706023323 xustar0030 mtime=1776590278.588591928 29 atime=1776590278.77873317 30 ctime=1776590281.945127349 nghttp2-1.69.0/doc/nghttp2_session_check_request_allowed.rst0000644000175100017510000000143115171116706023713 0ustar00runnerrunner nghttp2_session_check_request_allowed ===================================== Synopsis -------- *#include * .. function:: int nghttp2_session_check_request_allowed(nghttp2_session *session) Returns nonzero if new request can be sent from local endpoint.

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.

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.

Default: ``0`` .. option:: --worker-read-rate= Set maximum average read rate on frontend connection per worker. Setting 0 to this option means read rate is unlimited. Not implemented yet. Default: ``0`` .. option:: --worker-read-burst= Set maximum read burst size on frontend connection per worker. Setting 0 to this option means read burst size is unlimited. Not implemented yet. Default: ``0`` .. option:: --worker-write-rate= Set maximum average write rate on frontend connection per worker. Setting 0 to this option means write rate is unlimited. Not implemented yet. Default: ``0`` .. option:: --worker-write-burst= Set maximum write burst size on frontend connection per worker. Setting 0 to this option means write burst size is unlimited. Not implemented yet. Default: ``0`` .. option:: --worker-frontend-connections= Set maximum number of simultaneous connections frontend accepts. Setting 0 means unlimited. Default: ``0`` .. option:: --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 :option:`--http2-proxy` 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 :option:`--backend-connections-per-frontend`\. Default: ``8`` .. option:: --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. To limit the number of connections per host with :option:`--http2-proxy` option, use :option:`--backend-connections-per-host`\. Default: ``0`` .. option:: --rlimit-nofile= Set maximum number of open files (RLIMIT_NOFILE) to . If 0 is given, nghttpx does not set the limit. Default: ``0`` .. option:: --rlimit-memlock= Set maximum number of bytes of memory that may be locked into RAM. If 0 is given, nghttpx does not set the limit. Default: ``0`` .. option:: --backend-request-buffer= Set buffer size used to store backend request. Default: ``16K`` .. option:: --backend-response-buffer= Set buffer size used to store backend response. Default: ``128K`` .. option:: --fastopen= Enables "TCP Fast Open" for the listening socket and limits the maximum length for the queue of connections that have not yet completed the three-way handshake. If value is 0 then fast open is disabled. Default: ``0`` .. option:: --no-kqueue Don't use kqueue. This option is only applicable for the platforms which have kqueue. For other platforms, this option will be simply ignored. Timeout ~~~~~~~ .. option:: --frontend-http2-idle-timeout= Specify idle timeout for HTTP/2 frontend connection. If no active streams exist for this duration, connection is closed. Default: ``3m`` .. option:: --frontend-http3-idle-timeout= Specify idle timeout for HTTP/3 frontend connection. If no active streams exist for this duration, connection is closed. Default: ``3m`` .. option:: --frontend-write-timeout= Specify write timeout for all frontend connections. Default: ``30s`` .. option:: --frontend-keep-alive-timeout= Specify keep-alive timeout for frontend HTTP/1 connection. Default: ``1m`` .. option:: --frontend-header-timeout= Specify duration that the server waits for an HTTP request header fields to be received completely. On timeout, HTTP/1 and HTTP/2 connections are closed. For HTTP/3, the stream is shutdown, and the connection itself is left intact. Default: ``1m`` .. option:: --stream-read-timeout= Specify read timeout for HTTP/2 streams. 0 means no timeout.

Default: ``10s`` .. option:: --backend-http2-settings-timeout= Specify timeout before SETTINGS ACK is received from backend server. Default: ``10s`` .. option:: --backend-max-backoff= Specify maximum backoff interval. 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`` SSL/TLS ~~~~~~~ .. option:: --ciphers= Set allowed cipher list for frontend connection. The format of the string is described in OpenSSL ciphers(1). This option sets cipher suites for TLSv1.2. Use :option:`--tls13-ciphers` for TLSv1.3. 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 frontend connection. The format of the string is described in OpenSSL ciphers(1). This option sets cipher suites for TLSv1.3. Use :option:`--ciphers` for TLSv1.2.

The supported curves depend on the linked OpenSSL library. This function requires OpenSSL >= 1.0.2. Default: ``X25519:P-256:P-384:P-521`` .. option:: -k, --insecure Don't verify backend server's certificate if TLS is enabled for backend connections. .. option:: --cacert= Set path to trusted CA certificate file. 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. Operator should handle the expired client certificate by some means (e.g., mruby script). Otherwise, this option might cause a security risk. .. option:: --client-private-key-file= Path to file that contains client private key used in backend client authentication. .. option:: --client-cert-file= Path to file that contains client certificate used in backend client authentication. .. option:: --tls-min-proto-version= Specify minimum SSL/TLS protocol. The name matching is done in case-insensitive manner. The versions between :option:`--tls-min-proto-version` and :option:`\--tls-max-proto-version` are enabled. If the protocol list advertised by client does not overlap this range, you will receive the error message "unknown protocol". The available versions are: TLSv1.3 and TLSv1.2 Default: ``TLSv1.2`` .. option:: --tls-max-proto-version= Specify maximum SSL/TLS protocol. The name matching is done in case-insensitive manner. The versions between :option:`--tls-min-proto-version` and :option:`\--tls-max-proto-version` are enabled. If the protocol list advertised by client does not overlap this range, you will receive the error message "unknown protocol". The available versions are: TLSv1.3 and TLSv1.2 Default: ``TLSv1.3`` .. option:: --tls-ticket-key-file= Path to file that contains random data to construct TLS session ticket parameters. If aes-128-cbc is given in :option:`--tls-ticket-key-cipher`\, the file must contain exactly 48 bytes. If aes-256-cbc is given in :option:`--tls-ticket-key-cipher`\, the file must contain exactly 80 bytes. This options can be used repeatedly to specify multiple ticket parameters. 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. 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:: --tls-ticket-key-memcached-interval= Set interval to get TLS ticket keys from memcached. Default: ``10m`` .. option:: --tls-ticket-key-memcached-max-retry= Set maximum number of consecutive retries before abandoning TLS ticket key retrieval. If this number is reached, the attempt is considered as failure, and "failure" count is incremented by 1, which contributed to the value controlled :option:`--tls-ticket-key-memcached-max-fail` option. Default: ``3`` .. option:: --tls-ticket-key-memcached-max-fail= Set maximum number of consecutive failure before disabling TLS ticket until next scheduled key retrieval. Default: ``2`` .. option:: --tls-ticket-key-cipher= Specify cipher to encrypt TLS session ticket. Specify either aes-128-cbc or aes-256-cbc. 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 . See :option:`--ech-retry-config-file` for details. .. option:: --ech-retry-config-file= This option and :option:`--ech-config-file` option read Encrypted Client Hello (ECH) server configuration from . If :option:`--ech-retry-config-file` is used, the configurations are included in the retry configurations. The file format must be PEM ECH file described in RFC 9934. These options can be used repeatedly to read multiple files. :option:`--ech-retry-config-file` must be used at least once when enabling ECH. HTTP/2 ~~~~~~ .. option:: -c, --frontend-http2-max-concurrent-streams= Set the maximum number of the concurrent streams in one frontend HTTP/2 session. Default: ``100`` .. option:: --backend-http2-max-concurrent-streams= Set the maximum number of the concurrent streams in one backend HTTP/2 session. This sets maximum number of concurrent opened pushed streams. The maximum number of concurrent requests are set by a remote server. Default: ``100`` .. option:: --frontend-http2-window-size= Sets the per-stream initial window size of HTTP/2 frontend connection. Default: ``65535`` .. option:: --frontend-http2-connection-window-size= Sets the per-connection window size of HTTP/2 frontend connection.

Default: ``65535`` .. option:: --backend-http2-connection-window-size= Sets the per-connection window size of HTTP/2 backend connection. Default: ``2147483647`` .. option:: --http2-no-cookie-crumbling Don't crumble cookie header field. .. option:: --padding= Add at most bytes to a HTTP/2 frame payload as padding. 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. The maximum window size is capped by the value specified by :option:`--frontend-http2-connection-window-size`\. Since the stream is subject to stream level window size, it should be adjusted using :option:`--frontend-http2-window-size` option as well. This option is only effective on recent Linux platform. .. option:: --frontend-http2-encoder-dynamic-table-size= Specify the maximum dynamic table size of HPACK encoder in the frontend HTTP/2 connection.

The incoming HTTP/1.1 connection can be upgraded to HTTP/2 through HTTP Upgrade. .. option:: -s, --http2-proxy Like default mode, but enable forward proxy. This is so called HTTP/2 proxy mode. Logging ~~~~~~~ .. option:: -L, --log-level= Set the severity level of log output. must be one of INFO, NOTICE, WARN, ERROR and FATAL. Default: ``NOTICE`` .. option:: --accesslog-file= Set path to write access log. To reopen file, send USR1 signal to nghttpx. .. option:: --accesslog-syslog Send access log to syslog. If this option is used, :option:`--accesslog-file` option is ignored. .. option:: --accesslog-format= Specify format string for access log. The default format is combined format.

Default: ``$remote_addr - - [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent"`` .. option:: --accesslog-write-early Write access log when response header fields are received from backend rather than when request transaction finishes. .. option:: --errorlog-file= Set path to write error log. To reopen file, send USR1 signal to nghttpx. stderr will be redirected to the error log file unless :option:`--errorlog-syslog` is used. Default: ``/dev/stderr`` .. option:: --errorlog-syslog Send error log to syslog. If this option is used, :option:`--errorlog-file` option is ignored. .. option:: --syslog-facility= Set syslog facility to . Default: ``daemon`` HTTP ~~~~ .. option:: --add-x-forwarded-for Append X-Forwarded-For header field to the downstream request. .. option:: --strip-incoming-x-forwarded-for Strip X-Forwarded-For header field from inbound client requests. .. option:: --no-add-x-forwarded-proto Don't append additional X-Forwarded-Proto header field to the backend request. If inbound client sets X-Forwarded-Proto, and :option:`--no-strip-incoming-x-forwarded-proto` option is used, they are passed to the backend. .. option:: --no-strip-incoming-x-forwarded-proto Don't strip X-Forwarded-Proto header field from inbound client requests. .. option:: --add-forwarded= Append RFC 7239 Forwarded header field with parameters specified in comma delimited list . The supported parameters are "by", "for", "host", and "proto". By default, the value of "by" and "for" parameters are obfuscated string. See :option:`--forwarded-by` and :option:`--forwarded-for` options respectively. Note that nghttpx does not translate non-standard X-Forwarded-\* header fields into Forwarded header field, and vice versa. .. option:: --strip-incoming-forwarded Strip Forwarded header field from inbound client requests. .. option:: --forwarded-by=(obfuscated|ip|) Specify the parameter value sent out with "by" parameter of Forwarded header field. If "obfuscated" is given, the string is randomly generated at startup. If "ip" is given, the interface address of the connection, including port number, is sent with "by" parameter. In case of UNIX domain socket, "localhost" is used instead of address and port. User can also specify the static obfuscated string. The limitation is that it must start with "_", and only consists of character set [A-Za-z0-9._-], as described in RFC 7239. Default: ``obfuscated`` .. option:: --forwarded-for=(obfuscated|ip) Specify the parameter value sent out with "for" parameter of Forwarded header field. If "obfuscated" is given, the string is randomly generated for each client connection. If "ip" is given, the remote client address of the connection, without port number, is sent with "for" parameter. In case of UNIX domain socket, "localhost" is used instead of address. Default: ``obfuscated`` .. option:: --no-via Don't append to Via header field. If Via header field is received, it is left unaltered. .. option:: --no-strip-incoming-early-data Don't strip Early-Data header field from inbound client requests. .. option:: --no-location-rewrite Don't rewrite location header field in default mode. When :option:`--http2-proxy` is used, location header field will not be altered regardless of this option. .. option:: --host-rewrite Rewrite host and :authority header fields in default mode. When :option:`--http2-proxy` is used, these headers will not be altered regardless of this option. .. option:: --altsvc= Specify protocol ID, port, host and origin of alternative service. , and are optional. Empty and are allowed and they are treated as nothing is specified. They are advertised in alt-svc header field only in HTTP/1.1 frontend. This option can be used multiple times to specify multiple alternative services. Example: :option:`--altsvc`\="h2,443,,,ma=3600; persist=1" .. option:: --http2-altsvc= Just like :option:`--altsvc` option, but this altsvc is only sent in HTTP/2 frontend. .. option:: --add-request-header=
Specify additional header field to add to request header set. The field name must be lowercase. This option just appends header field and won't replace anything already set. This option can be used several times to specify multiple header fields. Example: :option:`--add-request-header`\="foo: bar" .. option:: --add-response-header=
Specify additional header field to add to response header set. The field name must be lowercase. This option just appends header field and won't replace anything already set.

Default: ``500`` .. option:: --error-page=(|*)= Set file path to custom error page served when nghttpx originally generates HTTP error status code . must be greater than or equal to 400, and at most 599. If "\*" is used instead of , it matches all HTTP status code. If error status code comes from backend server, the custom error pages are not used. .. option:: --server-name= Change server response header field value to . Default: ``nghttpx`` .. option:: --no-server-rewrite Don't rewrite server header field in default mode. 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: ``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. 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. This API returns response including ``data`` key. Its value is JSON object, and it contains at least the following key: configRevision The configuration revision of the current nghttpx SEE ALSO -------- :manpage:`nghttp(1)`, :manpage:`nghttpd(1)`, :manpage:`h2load(1)` nghttp2-1.69.0/doc/PaxHeaders/nghttp2_option_set_server_fallback_rfc7540_priorities.rst0000644000000000000000000000013215171116706026240 xustar0030 mtime=1776590278.586642204 30 atime=1776590278.708731877 30 ctime=1776590281.875080977 nghttp2-1.69.0/doc/nghttp2_option_set_server_fallback_rfc7540_priorities.rst0000644000175100017510000000071515171116706026633 0ustar00runnerrunner nghttp2_option_set_server_fallback_rfc7540_priorities ===================================================== Synopsis -------- *#include * .. function:: void nghttp2_option_set_server_fallback_rfc7540_priorities(nghttp2_option *option, int val) .. warning:: Deprecated. :rfc:`7540` priorities have been removed.

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. nghttp2-1.69.0/doc/sources/PaxHeaders/nghttpx-howto.rst0000644000000000000000000000013115171116653020074 xustar0030 mtime=1776590251.603722839 30 atime=1776590256.535313858 29 ctime=1776590282.06499371 nghttp2-1.69.0/doc/sources/nghttpx-howto.rst0000644000175100017510000006033315171116653020472 0ustar00runnerrunner.. program:: nghttpx nghttpx - HTTP/2 proxy - HOW-TO =============================== :doc:`nghttpx.1` is a proxy translating protocols between HTTP/2 and other protocols (e.g., HTTP/1). 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. nghttp2-1.69.0/doc/sources/PaxHeaders/contribute.rst0000644000000000000000000000013215171116653017421 xustar0030 mtime=1776590251.603722839 30 atime=1776590256.535313858 30 ctime=1776590282.069005837 nghttp2-1.69.0/doc/sources/contribute.rst0000644000175100017510000000453215171116653020015 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. nghttp2-1.69.0/doc/sources/PaxHeaders/tutorial-hpack.rst0000644000000000000000000000013215171116653020172 xustar0030 mtime=1776590251.603722839 30 atime=1776590256.535313858 30 ctime=1776590282.063528143 nghttp2-1.69.0/doc/sources/tutorial-hpack.rst0000644000175100017510000001307015171116653020563 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()`. nghttp2-1.69.0/doc/sources/PaxHeaders/index.rst0000644000000000000000000000013215171116653016352 xustar0030 mtime=1776590251.603722839 30 atime=1776590256.535313858 30 ctime=1776590282.059130298 nghttp2-1.69.0/doc/sources/index.rst0000644000175100017510000000215315171116653016743 0ustar00runnerrunner.. nghttp2 documentation main file, created by sphinx-quickstart on Sun Mar 11 22:57:49 2012.

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. nghttp2-1.69.0/doc/sources/PaxHeaders/h2load-howto.rst0000644000000000000000000000013215171116653017552 xustar0030 mtime=1776590251.603722839 30 atime=1776590256.535313858 30 ctime=1776590282.066358637 nghttp2-1.69.0/doc/sources/h2load-howto.rst0000644000175100017510000001131715171116653020145 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`. nghttp2-1.69.0/doc/sources/PaxHeaders/building-android-binary.rst0000644000000000000000000000013215171116653021740 xustar0030 mtime=1776590251.602222903 30 atime=1776590256.535313858 30 ctime=1776590282.067682182 nghttp2-1.69.0/doc/sources/building-android-binary.rst0000644000175100017510000000627215171116653022337 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 $ $NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/llvm-strip src/nghttpx nghttp2-1.69.0/doc/PaxHeaders/bash_completion0000644000000000000000000000013215171116712016113 xustar0030 mtime=1776590282.082794197 30 atime=1776590282.128795047 30 ctime=1776590282.082794197 nghttp2-1.69.0/doc/bash_completion/0000755000175100017510000000000015171116712016560 5ustar00runnerrunnernghttp2-1.69.0/doc/bash_completion/PaxHeaders/nghttp0000644000000000000000000000013215171116653017423 xustar0030 mtime=1776590251.601021949 30 atime=1776590256.533313821 30 ctime=1776590282.079874966 nghttp2-1.69.0/doc/bash_completion/nghttp0000644000175100017510000000141515171116653020014 0ustar00runnerrunner_nghttp() { local cur prev split=false COMPREPLY=() COMP_WORDBREAKS=${COMP_WORDBREAKS//=} cmd=${COMP_WORDS[0]} _get_comp_words_by_ref cur prev case $cur in -*) COMPREPLY=( $( compgen -W '--verbose --null-out --remote-name --timeout --window-bits --connection-window-bits --get-assets --stat --header --trailer --cert --key --data --multiply --upgrade --extpri --peer-max-concurrent-streams --header-table-size --encoder-header-table-size --padding --har --color --continuation --no-content-length --hexdump --no-push --max-concurrent-streams --expect-continue --no-verify-peer --ktls --version --help ' -- "$cur" ) ) ;;

Use `nghttp2_session_mem_send2()` instead. Returns the serialized data to send. This function behaves like `nghttp2_session_send()` except that it does not use :type:`nghttp2_send_callback` 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_send()` 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. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_session_get_stream_user_data.rst0000644000000000000000000000013215171116706023151 xustar0030 mtime=1776590278.589835513 30 atime=1776590278.819733927 30 ctime=1776590281.986239641 nghttp2-1.69.0/doc/nghttp2_session_get_stream_user_data.rst0000644000175100017510000000124415171116706023542 0ustar00runnerrunner nghttp2_session_get_stream_user_data ==================================== Synopsis -------- *#include * .. function:: void * nghttp2_session_get_stream_user_data(nghttp2_session *session, int32_t stream_id) Returns stream_user_data for the stream *stream_id*.

The *pri_spec* is ignored. 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 request HEADERS. See the specification for more details. If *data_prd* is not ``NULL``, it provides data which will be sent in subsequent DATA frames. In this case, a method that allows request message bodies (https://tools.ietf.org/html/rfc7231#section-4) must be specified with ``:method`` key in *nva* (e.g. ``POST``). 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 have END_STREAM set. The *stream_user_data* is data associated to the stream opened by this request and can be an arbitrary pointer, which can be retrieved later by `nghttp2_session_get_stream_user_data()`. This function returns assigned stream ID 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_STREAM_ID_NOT_AVAILABLE` No stream ID is available because maximum stream ID was reached. :enum:`nghttp2_error.NGHTTP2_ERR_PROTO` The *session* is server session. .. warning:: This function returns assigned stream ID if it succeeds. But that stream is not created yet. The application must not submit frame to that stream ID before :type:`nghttp2_before_frame_send_callback` is called for this frame. This means `nghttp2_session_get_stream_user_data()` does not work before the callback. But `nghttp2_session_set_stream_user_data()` handles this situation specially, and it can set data to a stream during this period. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_session_callbacks_set_send_data_callback.rst0000644000000000000000000000013015171116706025376 xustar0030 mtime=1776590278.588434051 30 atime=1776590278.773733077 28 ctime=1776590281.9395599 nghttp2-1.69.0/doc/nghttp2_session_callbacks_set_send_data_callback.rst0000644000175100017510000000073715171116706025777 0ustar00runnerrunner nghttp2_session_callbacks_set_send_data_callback ================================================ Synopsis -------- *#include * .. function:: void nghttp2_session_callbacks_set_send_data_callback( nghttp2_session_callbacks *cbs, nghttp2_send_data_callback send_data_callback) Sets callback function invoked when :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_NO_COPY` is used in :type:`nghttp2_data_source_read_callback2` to avoid data copy. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_submit_trailer.rst0000644000000000000000000000013215171116706020252 xustar0030 mtime=1776590278.591957555 30 atime=1776590278.884735127 30 ctime=1776590282.054274025 nghttp2-1.69.0/doc/nghttp2_submit_trailer.rst0000644000175100017510000000522715171116706020650 0ustar00runnerrunner nghttp2_submit_trailer ====================== Synopsis -------- *#include * .. function:: int nghttp2_submit_trailer(nghttp2_session *session, int32_t stream_id, const nghttp2_nv *nva, size_t nvlen) Submits trailer fields HEADERS against the stream *stream_id*.

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. For server, trailer fields must follow response HEADERS or response DATA without END_STREAM flat set. The library does not enforce this requirement, and applications should do this for themselves. If `nghttp2_submit_trailer()` is called before any response HEADERS submission (usually by `nghttp2_submit_response2()`), the content of *nva* will be sent as response headers, which will result in error. This function has the same effect with `nghttp2_submit_headers()`, with flags = :enum:`nghttp2_flag.NGHTTP2_FLAG_END_STREAM` and both pri_spec and stream_user_data to NULL. To submit trailer fields after `nghttp2_submit_response2()` is called, the application has to specify :type:`nghttp2_data_provider2` to `nghttp2_submit_response2()`.

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.

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.

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.

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. It persists until request finishes. So values set in request phase hook can be retrieved in response phase hook. .UNINDENT .INDENT 7.0 .TP .B attribute [R] phase Return the current phase. .UNINDENT .INDENT 7.0 .TP .B attribute [R] remote_addr Return IP address of a remote client. If connection is made via UNIX domain socket, this returns the string \(dqlocalhost\(dq. .UNINDENT .INDENT 7.0 .TP .B attribute [R] server_addr Return address of server that accepted the connection. This is a string which specified in \fB\-\-frontend\fP option, excluding port number, and not a resolved IP address. For UNIX domain socket, this is a path to UNIX domain socket. .UNINDENT .INDENT 7.0 .TP .B attribute [R] server_port Return port number of the server frontend which accepted the connection from client. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_used Return true if TLS is used on the connection. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_sni Return the TLS SNI value which client sent in this connection. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_client_fingerprint_sha256 Return the SHA\-256 fingerprint of a client certificate. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_client_fingerprint_sha1 Return the SHA\-1 fingerprint of a client certificate. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_client_issuer_name Return the issuer name of a client certificate. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_client_subject_name Return the subject name of a client certificate. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_client_serial Return the serial number of a client certificate. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_client_not_before Return the start date of a client certificate in seconds since the epoch. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_client_not_after Return the end date of a client certificate in seconds since the epoch. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_cipher Return a TLS cipher negotiated in this connection. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_protocol Return a TLS protocol version negotiated in this connection. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_session_id Return a session ID for this connection in hex string. .UNINDENT .INDENT 7.0 .TP .B attribute [R] tls_session_reused Return true if, and only if a SSL/TLS session is reused. .UNINDENT .INDENT 7.0 .TP .B attribute [R] alpn Return ALPN identifier negotiated in this connection. .UNINDENT .INDENT 7.0 .TP .B attribute [R] 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. .UNINDENT .UNINDENT .INDENT 0.0 .TP .B class Nghttpx::Request Object to represent request from client. The modification to Request object is allowed only in request phase hook. .INDENT 7.0 .TP .B attribute [R] http_version_major Return HTTP major version. .UNINDENT .INDENT 7.0 .TP .B attribute [R] http_version_minor Return HTTP minor version. .UNINDENT .INDENT 7.0 .TP .B attribute [R/W] method HTTP method. On assignment, copy of given value is assigned. We don\(aqt accept arbitrary method name. We will document them later, but well known methods, like GET, PUT and POST, are all supported. .UNINDENT .INDENT 7.0 .TP .B attribute [R/W] authority Authority (i.e., example.org), including optional port component . On assignment, copy of given value is assigned. .UNINDENT .INDENT 7.0 .TP .B attribute [R/W] scheme Scheme (i.e., http, https). On assignment, copy of given value is assigned. .UNINDENT .INDENT 7.0 .TP .B attribute [R/W] 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 \%), 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. Use \fBNghttpx::Request#add_header\fP or \fBNghttpx::Request#set_header\fP to change request header fields. .UNINDENT .INDENT 7.0 .TP .B 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. .UNINDENT .INDENT 7.0 .TP .B 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. .UNINDENT .INDENT 7.0 .TP .B clear_headers() Clear all existing request header fields. .UNINDENT .INDENT 7.0 .TP .B push(uri) Initiate to push resource identified by \fIuri\fP\&. Only HTTP/2 protocol supports this feature. For the other protocols, this method is noop. \fIuri\fP 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. .UNINDENT .UNINDENT .INDENT 0.0 .TP .B class Nghttpx::Response Object to represent response from backend server. .INDENT 7.0 .TP .B attribute [R] http_version_major Return HTTP major version. .UNINDENT .INDENT 7.0 .TP .B attribute [R] http_version_minor Return HTTP minor version. .UNINDENT .INDENT 7.0 .TP .B attribute [R/W] 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. .UNINDENT .INDENT 7.0 .TP .B attribute [R] 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 \fBNghttpx::Response#add_header\fP or \fBNghttpx::Response#set_header\fP to change response header fields. .UNINDENT .INDENT 7.0 .TP .B 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. .UNINDENT .INDENT 7.0 .TP .B 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. .UNINDENT .INDENT 7.0 .TP .B clear_headers() Clear all existing response header fields. .UNINDENT .INDENT 7.0 .TP .B return(body) Return custom response \fIbody\fP 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 \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.

Of course, all data except for last one must not have :enum:`nghttp2_flag.NGHTTP2_FLAG_END_STREAM` flag set in *flags*. This sounds a bit complicated, and we recommend to use `nghttp2_submit_request()` and `nghttp2_submit_response()` to avoid this cascading issue.

This is the amount of flow-controlled payload (e.g., DATA) that the local endpoint can send without stream level WINDOW_UPDATE. There is also connection level flow control, so the effective size of payload that the local endpoint can actually send is min(`nghttp2_session_get_stream_remote_window_size()`, `nghttp2_session_get_remote_window_size()`).

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).

This function retrieves the highest prioritized frame from the outbound queue and sends it to the remote peer. It does this as many times as possible until the user callback :type:`nghttp2_send_callback2` returns :enum:`nghttp2_error.NGHTTP2_ERR_WOULDBLOCK`, the outbound queue becomes empty or flow control is triggered (remote window size becomes depleted or maximum number of concurrent streams is reached). 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. Get the next frame to send from outbound queue. 2. Prepare transmission of the frame. 3. If the control frame cannot be sent because some preconditions are not met (e.g., request HEADERS cannot be sent after GOAWAY), :type:`nghttp2_on_frame_not_send_callback` is invoked. Abort the following steps. 4. If the frame is HEADERS, PUSH_PROMISE or DATA, :type:`nghttp2_select_padding_callback` is invoked. 5. If the frame is request HEADERS, the stream is opened here. 6. :type:`nghttp2_before_frame_send_callback` is invoked. 7. If :enum:`nghttp2_error.NGHTTP2_ERR_CANCEL` is returned from :type:`nghttp2_before_frame_send_callback`, the current frame transmission is canceled, and :type:`nghttp2_on_frame_not_send_callback` is invoked. Abort the following steps. 8. :type:`nghttp2_send_callback2` is invoked one or more times to send the frame. 9. :type:`nghttp2_on_frame_send_callback` is invoked. 10.

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).

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.

It is a token-bucket based rate limiter. *burst* specifies the number of tokens that is initially available. The maximum number of tokens is capped to this value. *rate* specifies the number of tokens that are regenerated per second. When a suspicious activity is detected, some amount of tokens are consumed. If there is no token available, GOAWAY is sent to tear down the connection. *burst* and *rate* default to 10000 and 330 respectively. nghttp2-1.69.0/doc/PaxHeaders/mkapiref.py0000644000000000000000000000013115171116653015175 xustar0030 mtime=1776590251.601021949 29 atime=1776590256.53431384 30 ctime=1776590281.796139257 nghttp2-1.69.0/doc/mkapiref.py0000755000175100017510000002572715171116653015606 0ustar00runnerrunner#!/usr/bin/env python3 # -*- coding: utf-8 -*- # nghttp2 - HTTP/2 C Library # # Copyright (c) 2020 nghttp2 contributors # Copyright (c) 2020 ngtcp2 contributors # Copyright (c) 2012 Tatsuhiro Tsujikawa # # Permission is hereby granted, free of charge, to any person obtaining # a copy of this software and associated documentation files (the # "Software"), to deal in the Software without restriction, including # without limitation the rights to use, copy, modify, merge, publish, # distribute, sublicense, and/or sell copies of the Software, and to # permit persons to whom the Software is furnished to do so, subject to # the following conditions: # The above copyright notice and this permission notice shall be # included in all copies or substantial portions of the Software. # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, # EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF # MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND # NONINFRINGEMENT.

Use :type:`nghttp2_data_source_read_callback2` instead. Callback function invoked when the library wants to read data from the *source*. The read data is sent in the stream *stream_id*. The implementation of this function must read at most *length* bytes of data from *source* (or possibly other places) and store them in *buf* and return number of data stored in *buf*. If EOF is reached, set :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_EOF` flag in *\*data_flags*. Sometime it is desirable to avoid copying data into *buf* and let application to send data directly. To achieve this, set :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_NO_COPY` to *\*data_flags* (and possibly other flags, just like when we do copy), and return the number of bytes to send without copying data into *buf*. The library, seeing :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_NO_COPY`, will invoke :type:`nghttp2_send_data_callback`. The application must send complete DATA frame in that callback. If this callback is set by `nghttp2_submit_request()`, `nghttp2_submit_response()` or `nghttp2_submit_headers()` and `nghttp2_submit_data()` with flag parameter :enum:`nghttp2_flag.NGHTTP2_FLAG_END_STREAM` set, and :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_EOF` flag is set to *\*data_flags*, DATA frame will have END_STREAM flag set. Usually, this is expected behaviour and all are fine. One exception is send trailer fields. You cannot send trailer fields after sending frame with END_STREAM set. To avoid this problem, one can set :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_NO_END_STREAM` along with :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_EOF` to signal the library not to set END_STREAM in DATA frame. Then application can use `nghttp2_submit_trailer()` to send trailer fields. `nghttp2_submit_trailer()` can be called inside this callback. If the application wants to postpone DATA frames (e.g., asynchronous I/O, or reading data blocks for long time), it is achieved by returning :enum:`nghttp2_error.NGHTTP2_ERR_DEFERRED` without reading any data in this invocation. The library removes DATA frame from the outgoing queue temporarily. To move back deferred DATA frame to outgoing queue, call `nghttp2_session_resume_data()`. By default, *length* is limited to 16KiB at maximum. If peer allows larger frames, application can enlarge transmission buffer size. See :type:`nghttp2_data_source_read_length_callback` for more details. If the application just wants to return from `nghttp2_session_send()` or `nghttp2_session_mem_send()` without sending anything, return :enum:`nghttp2_error.NGHTTP2_ERR_PAUSE`. In case of error, there are 2 choices. Returning :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` will close the stream by issuing RST_STREAM with :enum:`nghttp2_error_code.NGHTTP2_INTERNAL_ERROR`. 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`. Returning :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE` will signal the entire session failure. .. type:: nghttp2_ssize (*nghttp2_data_source_read_callback2)( nghttp2_session *session, int32_t stream_id, uint8_t *buf, size_t length, uint32_t *data_flags, nghttp2_data_source *source, void *user_data) Callback function invoked when the library wants to read data from the *source*.

If EOF is reached, set :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_EOF` flag in *\*data_flags*. Sometime it is desirable to avoid copying data into *buf* and let application to send data directly. To achieve this, set :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_NO_COPY` to *\*data_flags* (and possibly other flags, just like when we do copy), and return the number of bytes to send without copying data into *buf*. The library, seeing :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_NO_COPY`, will invoke :type:`nghttp2_send_data_callback`. The application must send complete DATA frame in that callback. If this callback is set by `nghttp2_submit_request2()`, `nghttp2_submit_response2()` or `nghttp2_submit_headers()` and `nghttp2_submit_data2()` with flag parameter :enum:`nghttp2_flag.NGHTTP2_FLAG_END_STREAM` set, and :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_EOF` flag is set to *\*data_flags*, DATA frame will have END_STREAM flag set. Usually, this is expected behaviour and all are fine. One exception is send trailer fields. You cannot send trailer fields after sending frame with END_STREAM set. To avoid this problem, one can set :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_NO_END_STREAM` along with :enum:`nghttp2_data_flag.NGHTTP2_DATA_FLAG_EOF` to signal the library not to set END_STREAM in DATA frame. Then application can use `nghttp2_submit_trailer()` to send trailer fields. `nghttp2_submit_trailer()` can be called inside this callback. If the application wants to postpone DATA frames (e.g., asynchronous I/O, or reading data blocks for long time), it is achieved by returning :enum:`nghttp2_error.NGHTTP2_ERR_DEFERRED` without reading any data in this invocation. The library removes DATA frame from the outgoing queue temporarily. To move back deferred DATA frame to outgoing queue, call `nghttp2_session_resume_data()`. By default, *length* is limited to 16KiB at maximum. If peer allows larger frames, application can enlarge transmission buffer size. See :type:`nghttp2_data_source_read_length_callback` for more details. If the application just wants to return from `nghttp2_session_send()` or `nghttp2_session_mem_send2()` without sending anything, return :enum:`nghttp2_error.NGHTTP2_ERR_PAUSE`. In case of error, there are 2 choices. Returning :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` will close the stream by issuing RST_STREAM with :enum:`nghttp2_error_code.NGHTTP2_INTERNAL_ERROR`. 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`. Returning :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE` will signal the entire session failure. .. type:: nghttp2_data_provider .. warning:: Deprecated.

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 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 memory by pointed by the *data* is retained until `nghttp2_session_mem_recv2()` or `nghttp2_session_recv()` is called. The application must retain the input bytes which was used to produce the *data* parameter, because it may refer to the memory region included in the input bytes. 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()` and `nghttp2_session_mem_recv2()` functions immediately return :enum:`nghttp2_error.NGHTTP2_ERR_CALLBACK_FAILURE`.

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.

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`.

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`.

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. Also header fields which includes upper cased latter are also treated as error without passing them to this callback. This callback is only considered if HTTP messaging validation is turned on (which is on by default, see `nghttp2_option_set_no_http_messaging()`). With this callback, application inspects the incoming invalid field, and it also can reset stream from this callback by returning :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. By default, the error code is :enum:`nghttp2_error_code.NGHTTP2_PROTOCOL_ERROR`. To change the error code, call `nghttp2_submit_rst_stream()` with the error code of choice in addition to returning :enum:`nghttp2_error.NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. If 0 is returned, the header field is ignored, and the stream is not reset. .. type:: int (*nghttp2_on_invalid_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 an invalid header name/value pair is received for the *frame*. The parameter and behaviour are similar to :type:`nghttp2_on_header_callback2`. The difference is that this callback is only invoked when an invalid header name/value pair is received which is silently ignored if neither this callback nor :type:`nghttp2_on_invalid_header_callback` is set. Only invalid regular header field are passed to this callback. In other words, invalid pseudo header field is not passed to this callback.

The local window size can be adjusted by `nghttp2_submit_window_update()`. This function takes into account that and returns effective window size. This function does not take into account the amount of received data from the remote endpoint. Use `nghttp2_session_get_local_window_size()` to know the amount of data the remote endpoint can send without receiving connection-level WINDOW_UPDATE frame. Note that each stream is still subject to the stream level flow control.

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. nghttp2-1.69.0/doc/PaxHeaders/nghttp2_hd_inflate_new2.rst0000644000000000000000000000013215171116706020255 xustar0030 mtime=1776590278.585781824 30 atime=1776590278.685731452 30 ctime=1776590281.851218854 nghttp2-1.69.0/doc/nghttp2_hd_inflate_new2.rst0000644000175100017510000000121015171116706020637 0ustar00runnerrunner nghttp2_hd_inflate_new2 ======================= Synopsis -------- *#include * .. function:: int nghttp2_hd_inflate_new2(nghttp2_hd_inflater **inflater_ptr, nghttp2_mem *mem) Like `nghttp2_hd_inflate_new()`, but with additional custom memory allocator specified in the *mem*. The *mem* can be ``NULL`` and the call is equivalent to `nghttp2_hd_inflate_new()`. This function does not take ownership *mem*. The application is responsible for freeing *mem*.

Submitting these frames more than once before first DATA or HEADERS is finished results in :enum:`nghttp2_error.NGHTTP2_ERR_DATA_EXIST` error code. The earliest callback which tells that previous frame is done is :type:`nghttp2_on_frame_send_callback`. In side that callback, new data can be submitted using `nghttp2_submit_data2()`. Of course, all data except for last one must not have :enum:`nghttp2_flag.NGHTTP2_FLAG_END_STREAM` flag set in *flags*. This sounds a bit complicated, and we recommend to use `nghttp2_submit_request2()` and `nghttp2_submit_response2()` to avoid this cascading issue.

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()`). nghttp2-1.69.0/doc/PaxHeaders/nghttp2_priority_spec_default_init.rst0000644000000000000000000000013215171116706022647 xustar0030 mtime=1776590278.586885048 30 atime=1776590278.722732135 30 ctime=1776590281.888770566 nghttp2-1.69.0/doc/nghttp2_priority_spec_default_init.rst0000644000175100017510000000105515171116706023240 0ustar00runnerrunner nghttp2_priority_spec_default_init ================================== Synopsis -------- *#include * .. function:: void nghttp2_priority_spec_default_init(nghttp2_priority_spec *pri_spec) .. warning:: Deprecated. :rfc:`7540` priorities are deprecated by :rfc:`9113`.

GENERATED by help2rst.py. DO NOT EDIT DIRECTLY. .. program:: h2load h2load(1) ========= SYNOPSIS -------- **h2load** [OPTIONS]... [URI]... 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.

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*. 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. This function returns the number of bytes processed 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_HEADER_COMP` Inflation process has failed. :enum:`nghttp2_error.NGHTTP2_ERR_BUFFER_ERROR` The header field name or value is too large.

Actually, nghttp2_session_add_rst_stream_continue does not add RST_STREAM if the stream is not found. There is a situation that the stream exists when nghttp2_submit_rst_stream is called, but it may be closed before actually sending RST_STREAM. Previously, we send the frame in this case hoping that this is noop on remote endpoint. This commit checks stream existence just before sending RST_STREAM, and if the stream is not found, cancel RST_STREAM. This is the consistent behavior of nghttp2_submit_rst_stream and fixes race condition. commit a581d84d990f7d11bc64f324bfac58a1fd5410dc Merge: c186b00b 8a8c319c Author: Tatsuhiro Tsujikawa <404610+tatsuhiro-t@users.noreply.github.com> AuthorDate: 2025-12-05 Commit: GitHub CommitDate: 2025-12-05 Merge pull request #2577 from nghttp2/remove-union-from-worker-id Remove union from WorkerID commit 8a8c319c72f8f63e12d26813808414f67a257f8e Author: Tatsuhiro Tsujikawa AuthorDate: 2025-12-05 Commit: Tatsuhiro Tsujikawa CommitDate: 2025-12-05 Remove union from WorkerID commit c186b00b5cbfbc5c1942a59293281da86e67ab12 Merge: 0c570c82 c322eec7 Author: Tatsuhiro Tsujikawa <404610+tatsuhiro-t@users.noreply.github.com> AuthorDate: 2025-12-05 Commit: GitHub CommitDate: 2025-12-05 Merge pull request #2576 from nghttp2/fix-union-usage-in-dpw Fix union usage in nghttp2_data_provider_wrap commit c322eec789745f7334bd6ede00ee1bdca18ad89d Author: Tatsuhiro Tsujikawa AuthorDate: 2025-12-05 Commit: Tatsuhiro Tsujikawa CommitDate: 2025-12-05 Fix union usage in nghttp2_data_provider_wrap commit 0c570c823d85aec0c1724bf5ea78e3df094077dd Merge: ba1747b9 d6f85b11 Author: Tatsuhiro Tsujikawa <404610+tatsuhiro-t@users.noreply.github.com> AuthorDate: 2025-12-02 Commit: GitHub CommitDate: 2025-12-02 Merge pull request #2575 from nghttp2/dependabot/go_modules/github.com/quic-go/quic-go-0.57.1 build(deps): bump github.com/quic-go/quic-go from 0.57.0 to 0.57.1 commit d6f85b11cef141905697abf5ffca759dca3bab9f Author: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> AuthorDate: 2025-12-01 Commit: GitHub CommitDate: 2025-12-01 build(deps): bump github.com/quic-go/quic-go from 0.57.0 to 0.57.1 Bumps [github.com/quic-go/quic-go](https://github.com/quic-go/quic-go) from 0.57.0 to 0.57.1. - [Release notes](https://github.com/quic-go/quic-go/releases) - [Commits](https://github.com/quic-go/quic-go/compare/v0.57.0...v0.57.1) --- updated-dependencies: - dependency-name: github.com/quic-go/quic-go dependency-version: 0.57.1 dependency-type: direct:production update-type: version-update:semver-patch ...

No need to cancel jobs on main because they should finish once committed. commit 800023a8e9726b5e60d3891c79b33a7a15f3bd0f Merge: a9573220 0b670492 Author: Tatsuhiro Tsujikawa <404610+tatsuhiro-t@users.noreply.github.com> AuthorDate: 2025-11-11 Commit: GitHub CommitDate: 2025-11-11 Merge pull request #2551 from trukna/cmake-fix-install-path lib/CMakeLists.txt: Fix NGHTTP2_CONFIG_INSTALL_DIR path commit a9573220408102ca53c3782775e54e8841e073e9 Merge: 61d3a684 a7fa441f Author: Tatsuhiro Tsujikawa <404610+tatsuhiro-t@users.noreply.github.com> AuthorDate: 2025-11-11 Commit: GitHub CommitDate: 2025-11-11 Merge pull request #2562 from nghttp2/src-remove-duplicated-test src: Remove the duplicated test commit a7fa441f0a2831dc5f22ac65d706d5287b0994ea Author: Tatsuhiro Tsujikawa AuthorDate: 2025-11-11 Commit: Tatsuhiro Tsujikawa CommitDate: 2025-11-11 src: Remove the duplicated test commit 61d3a684155ca90050b6add6183762e00a58fca6 Merge: 81b74b4e 476a5f80 Author: Tatsuhiro Tsujikawa <404610+tatsuhiro-t@users.noreply.github.com> AuthorDate: 2025-11-11 Commit: GitHub CommitDate: 2025-11-11 Merge pull request #2561 from nghttp2/src-simplify-dlist-remove src: Simplify DList::remove commit 476a5f805ed5e64fc78f5b854c3874a4dcb408de Author: Tatsuhiro Tsujikawa AuthorDate: 2025-11-11 Commit: Tatsuhiro Tsujikawa CommitDate: 2025-11-11 src: Simplify DList::remove commit 81b74b4e426ed7227cbb8378599b8aa326900ab3 Merge: e4454672 61cb0095 Author: Tatsuhiro Tsujikawa <404610+tatsuhiro-t@users.noreply.github.com> AuthorDate: 2025-11-11 Commit: GitHub CommitDate: 2025-11-11 Merge pull request #2559 from nghttp2/dependabot/go_modules/github.com/quic-go/quic-go-0.56.0 build(deps): bump github.com/quic-go/quic-go from 0.55.0 to 0.56.0 commit 61cb0095b3f2235e9ebc7ea43f807f620596b88c Author: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> AuthorDate: 2025-11-11 Commit: GitHub CommitDate: 2025-11-11 build(deps): bump github.com/quic-go/quic-go from 0.55.0 to 0.56.0 Bumps [github.com/quic-go/quic-go](https://github.com/quic-go/quic-go) from 0.55.0 to 0.56.0. - [Release notes](https://github.com/quic-go/quic-go/releases) - [Commits](https://github.com/quic-go/quic-go/compare/v0.55.0...v0.56.0) --- updated-dependencies: - dependency-name: github.com/quic-go/quic-go dependency-version: 0.56.0 dependency-type: direct:production update-type: version-update:semver-minor ...

The mruby programming language

mruby

GitHub Super-Linter
## What is mruby mruby is the lightweight implementation of the Ruby language complying to (part of) the [ISO standard][ISO-standard] with more recent features provided by Ruby 3.x. Also, its syntax is Ruby 3.x compatible except for pattern matching. You can link and embed mruby within your application. The "mruby" interpreter program and the interactive "mirb" shell are provided as examples. You can also compile Ruby programs into compiled byte code using the "mrbc" compiler. All these tools are located in the "bin" directory. "mrbc" can also generate compiled byte code in a C source file. See the "mrbtest" program under the "test" directory for an example. This achievement was sponsored by the Regional Innovation Creation R&D Programs of the Ministry of Economy, Trade and Industry of Japan. ## How to get mruby To get mruby, you can download the stable version 3.4.0 from the official mruby GitHub repository or clone the trunk of the mruby source tree with the "git clone" command. You can also install and compile mruby using [ruby-install](https://github.com/postmodern/ruby-install), [ruby-build](https://github.com/rbenv/ruby-build) or [rvm](https://github.com/rvm/rvm). The latest development version of mruby can be downloaded via the following URL: [https://github.com/mruby/mruby/zipball/master](https://github.com/mruby/mruby/zipball/master) The trunk of the mruby source tree can be checked out with the following command: ```console $ git clone https://github.com/mruby/mruby.git ``` ## mruby homepage The URL of the mruby homepage is: . ## Mailing list We don't have a mailing list, but you can use [GitHub issues](https://github.com/mruby/mruby/issues). ## How to compile, test, and install (mruby and gems) For the simplest case, type ```console rake all test ``` See the [compile.md](doc/guides/compile.md) file for the detail. ## Building documentation There are two sets of documentation in mruby: the mruby API (generated by YARD) and C API (Doxygen and Graphviz) To build both of them, simply go ```console rake doc ``` You can also view them in your browser ```console rake view_api rake view_capi ``` ## How to customize mruby (mrbgems) mruby contains a package manager called "mrbgems" that you can use to create extensions in C and/or Ruby. For a guide on how to use mrbgems, consult the [mrbgems.md](doc/guides/mrbgems.md) file, and for example code, refer to the [examples/mrbgems/](examples/mrbgems) folder. ## Index of Document - [About the Limitations of mruby](doc/limitations.md) - [About the Compile](doc/guides/compile.md) - [About the Debugger with the `mrdb` Command](doc/guides/debugger.md) - [About GC Arena](doc/guides/gc-arena-howto.md) - [About the mruby directory structure](doc/guides/hier.md) - [About Linking with `libmruby`](doc/guides/link.md) - [About Memory Allocator Customization](doc/guides/memory.md) - [About Build-time Configurations](doc/guides/mrbconf.md) - [About the Build-time Library Manager](doc/guides/mrbgems.md) - [About the Symbols](doc/guides/symbol.md) - [Internal Implementation / About Value Boxing](doc/internal/boxing.md) - [Internal Implementation / About mruby Virtual Machine Instructions](doc/internal/opcode.md) ## License mruby is released under the [MIT License](LICENSE). ## Note for License mruby has chosen a MIT License due to its permissive license allowing developers to target various environments such as embedded systems. However, the license requires the display of the copyright notice and license information in manuals for instance. Doing so for big projects can be complicated or troublesome. This is why mruby has decided to display "mruby developers" as the copyright name to make it simple conventionally. In the future, mruby might ask you to distribute your new code (that you will commit,) under the MIT License as a member of "mruby developers" but contributors will keep their copyright. (We did not intend for contributors to transfer or waive their copyrights, actual copyright holder name (contributors) will be listed in the [AUTHORS](AUTHORS) file.) Please ask us if you want to distribute your code under another license. ## How to Contribute To contribute to mruby, please refer to the [contribution guidelines][contribution-guidelines] and send a pull request to the [mruby GitHub repository](https://github.com/mruby/mruby).

Algorithm details are omitted. Instead, the implementation part is described below. == Object's Color Each object can be painted in three colors: * White - Unmarked. * Gray - Marked, But the child objects are unmarked. * Black - Marked, the child objects are also marked. Extra color * Red - Static (ROM object) no need to be collected. - All child objects should be Red as well. == Two White Types There are two white color types in a flip-flop fashion: White-A and White-B, which respectively represent the Current White color (the newly allocated objects in the current GC cycle) and the Sweep Target White color (the dead objects to be swept). A and B will be switched just at the beginning of the next GC cycle. At that time, all the dead objects have been swept, while the newly created objects in the current GC cycle which finally remains White are now regarded as dead objects. Instead of traversing all the White-A objects and painting them as White-B, just switch the meaning of White-A and White-B as this will be much cheaper. As a result, the objects we sweep in the current GC cycle are always left from the previous GC cycle. This allows us to sweep objects incrementally, without the disturbance of the newly created objects. == Execution Timing GC Execution Time and Each step interval are decided by live objects count. List of Adjustment API: * gc_interval_ratio_set * gc_step_ratio_set For details, see the comments for each function. == Write Barrier mruby implementer and C extension library writer must insert a write barrier when updating a reference from a field of an object. When updating a reference from a field of object A to object B, two different types of write barrier are available: * mrb_field_write_barrier - target B object for a mark. * mrb_write_barrier - target A object for a mark. == Generational Mode mruby's GC offers an Generational Mode while reusing the tri-color GC infrastructure. It will treat the Black objects as Old objects after each sweep phase, instead of painting them White. The key ideas are still the same as traditional generational GC: * Minor GC - just traverse the Young objects (Gray objects) in the mark phase, then only sweep the newly created objects, and leave the Old objects live. * Major GC - same as a full regular GC cycle. The difference from "traditional" generational GC is, that the major GC in mruby is triggered incrementally in a tri-color manner. For details, see the comments for each function. */ typedef struct RVALUE RVALUE; struct free_obj { MRB_OBJECT_HEADER; RVALUE *next; }; struct RVALUE_initializer { MRB_OBJECT_HEADER; char padding[sizeof(void*) * 4 - sizeof(uint32_t)];

If you find any bugs, please report it to us. Thank you. ## Support `-t` option as same as `--debug` option Support to `-t` option as same as `--debug` option. These options align with Bison behavior. So same as `--debug` option. ## Trace only explicit rules Support to trace only explicit rules. If you use `--trace=rules` option, it shows include mid-rule actions. If you want to show only explicit rules, you can use `--trace=only-explicit-rules` option. Example: ```yacc %{ %} %union { int i; } %token number %type program %% program : number { printf("%d", $1); } number { $$ = $1 + $3; } ; %% ``` Result of `--trace=rules`: ```console $ exe/lrama --trace=rules sample.y Grammar rules: $accept -> program YYEOF $@1 -> ε program -> number $@1 number ``` Result of `--trace=only-explicit-rules`: ```console $ exe/lrama --trace=explicit-rules sample.y Grammar rules: $accept -> program YYEOF program -> number number ``` ## Lrama 0.6.11 (2024-12-23) ### Add support for %type declarations using %nterm in Nonterminal Symbols Allow to use `%nterm` in Nonterminal Symbols for `%type` declarations. ```yacc %nterm nonterminal… ``` This directive is also supported for compatibility with Bison, and only non-terminal symbols are allowed. In other words, definitions like the following will result in an error: ```yacc %{ // Prologue %} %token EOI 0 "EOI" %nterm EOI %% program: /* empty */ ; ``` It show an error message like the following: ```command ❯ exe/lrama nterm.y nterm.y:6:7: symbol EOI redeclared as a nonterminal %nterm EOI ^^^ ``` ## Lrama 0.6.10 (2024-09-11) ### Aliased Named References for actions of RHS in parameterizing rules Allow to use aliased named references for actions of RHS in parameterizing rules. ```yacc %rule sum(X, Y): X[summand] '+' Y[addend] { $$ = $summand + $addend } ; ``` https://github.com/ruby/lrama/pull/410 ### Named References for actions of RHS in parameterizing rules caller side Allow to use named references for actions of RHS in parameterizing rules caller side. ```yacc opt_nl: '\n'?[nl] { $$ = $nl; } ; ``` https://github.com/ruby/lrama/pull/414 ### Widen the definable position of parameterizing rules Allow to define parameterizing rules in the middle of the grammar. ```yacc %rule defined_option(X): /* empty */ | X ; %% program : defined_option(number) | defined_list(number) ; %rule defined_list(X): /* empty */ /* <--- here */ | defined_list(X) number ; ``` https://github.com/ruby/lrama/pull/420 ### Report unused terminal symbols Support to report unused terminal symbols. Run `exe/lrama --report=terms` to show unused terminal symbols. ```console $ exe/lrama --report=terms sample/calc.y 11 Unused Terms 0 YYerror 1 YYUNDEF 2 '\\\\' 3 '\\13' 4 keyword_class2 5 tNUMBER 6 tPLUS 7 tMINUS 8 tEQ 9 tEQEQ 10 '>' ``` https://github.com/ruby/lrama/pull/439 ### Report unused rules Support to report unused rules. Run `exe/lrama --report=rules` to show unused rules. ```console $ exe/lrama --report=rules sample/calc.y 3 Unused Rules 0 unused_option 1 unused_list 2 unused_nonempty_list ``` https://github.com/ruby/lrama/pull/441 ### Ensure compatibility with Bison for `%locations` directive Support `%locations` directive to ensure compatibility with Bison. Change to `%locations` directive not set by default. https://github.com/ruby/lrama/pull/446 ### Diagnostics report for parameterizing rules redefine Support to warning redefined parameterizing rules. Run `exe/lrama -W` or `exe/lrama --warnings` to show redefined parameterizing rules. ```console $ exe/lrama -W sample/calc.y parameterizing rule redefined: redefined_method(X) parameterizing rule redefined: redefined_method(X) ``` https://github.com/ruby/lrama/pull/448 ### Support `-v` and `--verbose` option Support to `-v` and `--verbose` option. These options align with Bison behavior. So same as '--report=state' option. https://github.com/ruby/lrama/pull/457 ## Lrama 0.6.9 (2024-05-02) ### Callee side tag specification of parameterizing rules Allow to specify tag on callee side of parameterizing rules. ```yacc %union { int i; } %rule with_tag(X) : X { $$ = $1; } ; ``` ### Named References for actions of RHS in parameterizing rules Allow to use named references for actions of RHS in parameterizing rules. ```yacc %rule option(number): /* empty */ | number { $$ = $number; } ; ``` ## Lrama 0.6.8 (2024-04-29) ### Nested parameterizing rules with tag Allow to nested parameterizing rules with tag. ```yacc %union { int i; } %rule nested_nested_option(X): /* empty */ | X ; %rule nested_option(X): /* empty */ | nested_nested_option(X) ; %rule option(Y): /* empty */ | nested_option(Y) ; ``` ## Lrama 0.6.7 (2024-04-28) ### RHS of user defined parameterizing rules contains `'symbol'?`, `'symbol'+` and `'symbol'*`. User can use `'symbol'?`, `'symbol'+` and `'symbol'*` in RHS of user defined parameterizing rules. ``` %rule with_word_seps(X): /* empty */ | X ' '+ ; ``` ## Lrama 0.6.6 (2024-04-27) ### Trace actions Support trace actions for debugging. Run `exe/lrama --trace=actions` to show grammar rules with actions. ```console $ exe/lrama --trace=actions sample/calc.y Grammar rules with actions: $accept -> list, YYEOF {} list -> ε {} list -> list, LF {} list -> list, expr, LF { printf("=> %d\n", $2); } expr -> NUM {} expr -> expr, '+', expr { $$ = $1 + $3; } expr -> expr, '-', expr { $$ = $1 - $3; } expr -> expr, '*', expr { $$ = $1 * $3; } expr -> expr, '/', expr { $$ = $1 / $3; } expr -> '(', expr, ')' { $$ = $2; } ``` ### Inlining Support inlining for rules. The `%inline` directive causes all references to symbols to be replaced with its definition. ```yacc %rule %inline op: PLUS { + } | TIMES { * } ; %% expr : number { $$ = $1; } | expr op expr { $$ = $1 $2 $3; } ; ``` as same as ```yacc expr : number { $$ = $1; } | expr '+' expr { $$ = $1 + $3; } | expr '*' expr { $$ = $1 * $3; } ; ``` ## Lrama 0.6.5 (2024-03-25) ### Typed Midrule Actions User can specify the type of mid rule action by tag (``) instead of specifying it with in an action. ```yacc primary: k_case expr_value terms? { $$ = p->case_labels; p->case_labels = Qnil; } case_body k_end { ... } ``` can be written as ```yacc primary: k_case expr_value terms? { $$ = p->case_labels; p->case_labels = Qnil; } case_body k_end { ... } ``` `%destructor` for midrule action is invoked only when tag is specified by Typed Midrule Actions. Difference from Bison's Typed Midrule Actions is that tag is postposed in Lrama however it's preposed in Bison. Bison supports this feature from 3.1. ## Lrama 0.6.4 (2024-03-22) ### Parameterizing rules (preceded, terminated, delimited) Support `preceded`, `terminated` and `delimited` rules. ```text program: preceded(opening, X) // Expanded to program: preceded_opening_X preceded_opening_X: opening X ``` ``` program: terminated(X, closing) // Expanded to program: terminated_X_closing terminated_X_closing: X closing ``` ``` program: delimited(opening, X, closing) // Expanded to program: delimited_opening_X_closing delimited_opening_X_closing: opening X closing ``` https://github.com/ruby/lrama/pull/382 ### Support `%destructor` declaration User can set codes for freeing semantic value resources by using `%destructor`. In general, these resources are freed by actions or after parsing. However if syntax error happens in parsing, these codes may not be executed. Codes associated to `%destructor` are executed when semantic value is popped from the stack by an error. ```yacc %token NUM %type expr2 %type expr %destructor { printf("destructor for val1: %d\n", $$); } // printer for TAG %destructor { printf("destructor for val2: %d\n", $$); } %destructor { printf("destructor for expr: %d\n", $$); } expr // printer for symbol ``` Bison supports this feature from 1.75b. https://github.com/ruby/lrama/pull/385 ## Lrama 0.6.3 (2024-02-15) ### Bring Your Own Stack Provide functionalities for Bring Your Own Stack. Ruby’s Ripper library requires their own semantic value stack to manage Ruby Objects returned by user defined callback method. Currently Ripper uses semantic value stack (`yyvsa`) which is used by parser to manage Node. This hack introduces some limitation on Ripper. For example, Ripper can not execute semantic analysis depending on Node structure. Lrama introduces two features to support another semantic value stack by parser generator users. 1. Callback entry points User can emulate semantic value stack by these callbacks. Lrama provides these five callbacks. Registered functions are called when each event happen. For example %after-shift function is called when shift happens on original semantic value stack. - `%after-shift` function_name - `%before-reduce` function_name - `%after-reduce` function_name - `%after-shift-error-token` function_name - `%after-pop-stack` function_name 2. `$:n` variable to access index of each grammar symbols User also needs to access semantic value of their stack in grammar action. `$:n` provides the way to access to it. `$:n` is translated to the minus index from the top of the stack. For example ```yacc primary: k_if expr_value then compstmt if_tail k_end { /*% ripper: if!($:2, $:4, $:5) %*/ /* $:2 = -5, $:4 = -3, $:5 = -2. */ } ``` https://github.com/ruby/lrama/pull/367 ## Lrama 0.6.2 (2024-01-27) ### %no-stdlib directive If `%no-stdlib` directive is set, Lrama doesn't load Lrama standard library for parameterizing rules, stdlib.y. https://github.com/ruby/lrama/pull/344 ## Lrama 0.6.1 (2024-01-13) ### Nested parameterizing rules Allow to pass an instantiated rule to other parameterizing rules. ```yacc %rule constant(X) : X ; %rule option(Y) : /* empty */ | Y ; %% program : option(constant(number)) // Nested rule ; %% ``` Allow to use nested parameterizing rules when define parameterizing rules. ```yacc %rule option(x) : /* empty */ | X ; %rule double(Y) : Y Y ; %rule double_opt(A) : option(double(A)) // Nested rule ; %% program : double_opt(number) ; %% ``` https://github.com/ruby/lrama/pull/337 ## Lrama 0.6.0 (2023-12-25) ### User defined parameterizing rules Allow to define parameterizing rule by `%rule` directive. ```yacc %rule pair(X, Y): X Y { $$ = $1 + $2; } ; %% program: stmt ; stmt: pair(ODD, EVEN) | pair(EVEN, ODD) ; ``` https://github.com/ruby/lrama/pull/285 ## Lrama 0.5.11 (2023-12-02) ### Type specification of parameterizing rules Allow to specify type of rules by specifying tag, `` in below example. Tag is post-modification style. ```yacc %union { int i; } %% program : option(number) | number_alias? ; ``` https://github.com/ruby/lrama/pull/272 ## Lrama 0.5.10 (2023-11-18) ### Parameterizing rules (option, nonempty_list, list) Support function call style parameterizing rules for `option`, `nonempty_list` and `list`. https://github.com/ruby/lrama/pull/197 ### Parameterizing rules (separated_list) Support `separated_list` and `separated_nonempty_list` parameterizing rules. ```text program: separated_list(',', number) // Expanded to program: separated_list_number separated_list_number: ε separated_list_number: separated_nonempty_list_number separated_nonempty_list_number: number separated_nonempty_list_number: separated_nonempty_list_number ',' number ``` ``` program: separated_nonempty_list(',', number) // Expanded to program: separated_nonempty_list_number separated_nonempty_list_number: number separated_nonempty_list_number: separated_nonempty_list_number ',' number ``` https://github.com/ruby/lrama/pull/204 ## Lrama 0.5.9 (2023-11-05) ### Parameterizing rules (suffix) Parameterizing rules are template of rules. It's very common pattern to write "list" grammar rule like: ```yacc opt_args: /* none */ | args ; args: arg | args arg ``` Lrama supports these suffixes: - `?`: option - `+`: nonempty list - `*`: list Idea of Parameterizing rules comes from Menhir LR(1) parser generator (https://gallium.inria.fr/~fpottier/menhir/manual.html#sec32). https://github.com/ruby/lrama/pull/181 ## Lrama 0.5.7 (2023-10-23) ### Racc parser Replace Lrama's parser from hand written parser to LR parser generated by Racc. Lrama uses `--embedded` option to generate LR parser because Racc is changed from default gem to bundled gem by Ruby 3.3 (https://github.com/ruby/lrama/pull/132). https://github.com/ruby/lrama/pull/62 ## Lrama 0.5.4 (2023-08-17) ### Runtime configuration for error recovery Make error recovery function configurable on runtime by two new macros. - `YYMAXREPAIR`: Expected to return max length of repair operations. `%parse-param` is passed to this function. - `YYERROR_RECOVERY_ENABLED`: Expected to return bool value to determine error recovery is enabled or not. `%parse-param` is passed to this function. https://github.com/ruby/lrama/pull/74 ## Lrama 0.5.3 (2023-08-05) ### Error Recovery Support token insert base Error Recovery. `-e` option is needed to generate parser with error recovery functions. https://github.com/ruby/lrama/pull/44 ## Lrama 0.5.2 (2023-06-14) ### Named References Instead of positional references like `$1` or `$$`, named references allow to access to symbol by name. ```yacc primary: k_class cpath superclass bodystmt k_end { $primary = new_class($cpath, $bodystmt, $superclass); } ``` Alias name can be declared. ```yacc expr[result]: expr[ex-left] '+' expr[ex.right] { $result = $[ex-left] + $[ex.right]; } ``` Bison supports this feature from 2.5. ### Add parse params to some macros and functions `%parse-param` are added to these macros and functions to remove ytab.sed hack from Ruby. - `YY_LOCATION_PRINT` - `YY_SYMBOL_PRINT` - `yy_stack_print` - `YY_STACK_PRINT` - `YY_REDUCE_PRINT` - `yysyntax_error` https://github.com/ruby/lrama/pull/40 See also: https://github.com/ruby/ruby/pull/7807 ## Lrama 0.5.0 (2023-05-17) ### stdin mode When `-` is given as grammar file name, reads the grammar source from STDIN, and takes the next argument as the input file name. This mode helps pre-process a grammar source. https://github.com/ruby/lrama/pull/8 ## Lrama 0.4.0 (2023-05-13) This is the first version migrated to Ruby. This version generates "parse.c" compatible with Bison 3.8.2. nghttp2-1.69.0/third-party/mruby/tools/lrama/PaxHeaders/template0000644000000000000000000000013215171116710021652 xustar0030 mtime=1776590280.425763591 30 atime=1776590282.130795084 30 ctime=1776590280.425763591 nghttp2-1.69.0/third-party/mruby/tools/lrama/template/0000755000175100017510000000000015171116710022317 5ustar00runnerrunnernghttp2-1.69.0/third-party/mruby/tools/lrama/template/PaxHeaders/bison0000644000000000000000000000013215171116710022764 xustar0030 mtime=1776590280.557766029 30 atime=1776590282.130795084 30 ctime=1776590280.557766029 nghttp2-1.69.0/third-party/mruby/tools/lrama/template/bison/0000755000175100017510000000000015171116710023431 5ustar00runnerrunnernghttp2-1.69.0/third-party/mruby/tools/lrama/template/bison/PaxHeaders/_yacc.h0000644000000000000000000000013215171116657024302 xustar0030 mtime=1776590255.503141493 30 atime=1776590256.613315296 30 ctime=1776590280.558701589 nghttp2-1.69.0/third-party/mruby/tools/lrama/template/bison/_yacc.h0000644000175100017510000000335115171116657024674 0ustar00runnerrunner<%# b4_shared_declarations -%> <%-# b4_cpp_guard_open([b4_spec_mapped_header_file]) -%> <%- if output.spec_mapped_header_file -%> #ifndef <%= output.b4_cpp_guard__b4_spec_mapped_header_file %> # define <%= output.b4_cpp_guard__b4_spec_mapped_header_file %> <%- end -%> <%-# b4_declare_yydebug & b4_YYDEBUG_define -%> /* Debug traces. */ #ifndef YYDEBUG # define YYDEBUG 0 #endif #if YYDEBUG && !defined(yydebug) extern int yydebug; #endif <%= output.percent_code("requires") %> <%-# b4_token_enums_defines -%> /* Token kinds. */ #ifndef YYTOKENTYPE # define YYTOKENTYPE enum yytokentype { <%= output.token_enums -%> }; typedef enum yytokentype yytoken_kind_t; #endif <%-# b4_declare_yylstype -%> <%-# b4_value_type_define -%> /* Value type. */ #if ! defined YYSTYPE && ! defined YYSTYPE_IS_DECLARED union YYSTYPE { #line <%= output.grammar.union.lineno %> "<%= output.grammar_file_path %>" <%= output.grammar.union.braces_less_code %> #line [@oline@] [@ofile@] }; typedef union YYSTYPE YYSTYPE; # define YYSTYPE_IS_TRIVIAL 1 # define YYSTYPE_IS_DECLARED 1 #endif <%-# b4_location_type_define -%> /* Location type. */ #if ! defined YYLTYPE && ! defined YYLTYPE_IS_DECLARED typedef struct YYLTYPE YYLTYPE; struct YYLTYPE { int first_line; int first_column; int last_line; int last_column; }; # define YYLTYPE_IS_DECLARED 1 # define YYLTYPE_IS_TRIVIAL 1 #endif <%-# b4_declare_yyerror_and_yylex.

There are two types of # parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse # # Racc::Parser#do_parse is simple. # # It's yyparse() of yacc, and Racc::Parser#next_token is yylex(). # This method must returns an array like [TOKENSYMBOL, ITS_VALUE]. # EOF is [false, false]. # (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default. # If you want to change this, see the grammar reference. # # Racc::Parser#yyparse is little complicated, but useful. # It does not use Racc::Parser#next_token, instead it gets tokens from any iterator. # # For example, yyparse(obj, :scan) causes # calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+. # # == Debugging # # When debugging, "-v" or/and the "-g" option is helpful. # # "-v" creates verbose log file (.output). # "-g" creates a "Verbose Parser". # Verbose Parser prints the internal status when parsing. # But it's _not_ automatic. # You must use -g option and set +@yydebug+ to +true+ in order to get output. # -g option only creates the verbose parser. # # === Racc reported syntax error. # # Isn't there too many "end"? # grammar of racc file is changed in v0.10. # # Racc does not use '%' mark, while yacc uses huge number of '%' marks.. # # === Racc reported "XXXX conflicts". # # Try "racc -v xxxx.y". # It causes producing racc's internal log file, xxxx.output. # # === Generated parsers does not work correctly # # Try "racc -g xxxx.y". # This command let racc generate "debugging parser". # Then set @yydebug=true in your parser. # It produces a working log of your parser. # # == Re-distributing Racc runtime # # A parser, which is created by Racc, requires the Racc runtime module; # racc/parser.rb. # # Ruby 1.8.x comes with Racc runtime module, # you need NOT distribute Racc runtime files. # # If you want to include the Racc runtime module with your parser. # This can be done by using '-E' option: # # $ racc -E -omyparser.rb myparser.y # # This command creates myparser.rb which `includes' Racc runtime. # Only you must do is to distribute your parser file (myparser.rb). # # Note: parser.rb is ruby license, but your parser is not. # Your own parser is completely yours. module Racc unless defined?(Racc_No_Extensions) Racc_No_Extensions = false # :nodoc: end class Parser Racc_Runtime_Version = ::Racc::VERSION Racc_Runtime_Core_Version_R = ::Racc::VERSION begin if Object.const_defined?(:RUBY_ENGINE) and RUBY_ENGINE == 'jruby' require 'jruby' require 'racc/cparse-jruby.jar' com.headius.racc.Cparse.new.load(JRuby.runtime, false) else require 'racc/cparse' end unless new.respond_to?(:_racc_do_parse_c, true) raise LoadError, 'old cparse.so' end if Racc_No_Extensions raise LoadError, 'selecting ruby version of racc runtime core' end Racc_Main_Parsing_Routine = :_racc_do_parse_c # :nodoc: Racc_YY_Parse_Method = :_racc_yyparse_c # :nodoc: Racc_Runtime_Core_Version = Racc_Runtime_Core_Version_C # :nodoc: Racc_Runtime_Type = 'c' # :nodoc: rescue LoadError Racc_Main_Parsing_Routine = :_racc_do_parse_rb Racc_YY_Parse_Method = :_racc_yyparse_rb Racc_Runtime_Core_Version = Racc_Runtime_Core_Version_R Racc_Runtime_Type = 'ruby' end def Parser.racc_runtime_type # :nodoc: Racc_Runtime_Type end def _racc_setup @yydebug = false unless self.class::Racc_debug_parser @yydebug = false unless defined?(@yydebug) if @yydebug @racc_debug_out = $stderr unless defined?(@racc_debug_out) @racc_debug_out ||= $stderr end arg = self.class::Racc_arg arg[13] = true if arg.size < 14 arg end def _racc_init_sysvars @racc_state = [0] @racc_tstack = [] @racc_vstack = [] @racc_t = nil @racc_val = nil @racc_read_next = true @racc_user_yyerror = false @racc_error_status = 0 end # The entry point of the parser.
