define HELP
This Makefile assists in handling i18n related tasks during development. Files
that need to be checked into source control are put into the locales/ directory.
They are
locales/$(POT_NAME) - the POT file generated by 'make update-pot'
locales/$$LANG.po - the translations for $$LANG
Only the $$LANG.po files should be edited manually; this is usually done by
translators.
You can use the following targets:
i18n: refresh all the files in locales/ and recompile resources
update-pot: extract strings and update locales/$(POT_NAME)
locales/LANG.po: create translations for LANG
msgfmt: compile the translations into Java classes; this step is
needed to make translations available to the Clojure code
and produces Java class files in resources/
endef
# @todo lutter 2015-04-20: for projects that use libraries with their own
# translation, we need to combine all their translations into one big po
# file and then run msgfmt over that so that we only have to deal with one
# resource bundle

As mentioned briefly on the [Quick Start](Trapperkeeper-Quick-Start.md) page, Trapperkeeper relies on a `bootstrap.cfg` file to determine the list of services that it should load at startup. The other piece of the bootstrapping equation is setting up a `main` that calls Trapperkeeper's bootstrap code. Here we'll go into a bit more detail about both of these topics.
## `bootstrap.cfg`
The `bootstrap.cfg` file is a simple text file, in which each line contains the fully qualified namespace and name of a service. Here's an example `bootstrap.cfg` that enables the nREPL service and a custom `foo-service`:
```
puppetlabs.trapperkeeper.services.nrepl.nrepl-service/nrepl-service
my.custom.namespace/foo-service
```
Note that it does not matter what order the services are specified in; trapperkeeper will resolve the dependencies between them, and start and stop them in the correct order based on their dependency relationships.
In normal use cases, you'll want to simply put `bootstrap.cfg` in your `resources` directory and bundle it as part of your application (e.g. in an uberjar). However, there are cases where you may want to override the list of services (for development, customizations, etc.). To accommodate this, Trapperkeeper will actually search in three different places for the `bootstrap.cfg` file; the first one it finds will be used. Here they are, listed in order of precedence:
* a location or list of locations ([see here](Command-Line-Arguments.md#multiple-bootstrap-files)) specified via the optional `--bootstrap-config` parameter on the command line when the application is launched
* in the current working directory
* on the classpath
## Configuration
Bootstrapping determines _which_ services should be loaded, but it doesn't say _how_ they should be configured. For that, you'll want to learn about the [built-in service](Built-in-Services.md#configuration-service) that Trapperkeeper uses to read configuration data.
OpenVoxProject-trapperkeeper-49527b2/documentation/Built-in-Configuration-Service.md 0000664 0000000 0000000 00000010425 15224541352 0030654 0 ustar 00root root 0000000 0000000 # Trapperkeeper's Built-in Configuration Service
The configuration service is built-in to Trapperkeeper and is always loaded. It performs the following tasks at application startup:
* Reads all application configuration into memory
* Initializes logging
* Provides functions that can be injected into other services to give them access to the configuration data
In its current form, the configuration service has some fairly rigid behavior though in the future we hope to make it more dynamic.
## Loading configuration data
All configuration data is read from config files on disk. When launching a Trapperkeeper application, you specify a `--config` command-line argument, whose value is a file path or comma-separated list of file paths. You may specify the path to a single config file, or you may specify a directory of config files. If no path is specified, Trapperkeeper will act as if you had passed it an empty configuration file.
We support several types of files for expressing the configuration data:
* `.ini` files
* `.edn` files (Clojure's [Extensible Data Notation](https://github.com/edn-format/edn) format)
* `.conf` files (this is the [Human-Optimized Config Object Notation](https://github.com/typesafehub/config/blob/master/HOCON.md) format; a flexible superset of JSON defined by the [typesafe config library](https://github.com/typesafehub/config))
* `.json` files
* `.properties` files
The configuration service will then parse the config file(s) into memory as a nested map; e.g., the section headers from an `.ini` file would become the top-level keys of the map, and the values will be maps containing the individual setting names and values from that section of the ini file. (If using `.edn`, `.conf`, or `.json`, you can control the nesting of the map more explicitly.)
Here's the protocol for the configuration service:
```clj
(defprotocol ConfigService
(get-config [this] "Returns a map containing all of the configuration values")
(get-in-config [this ks] [this ks default]
"Returns the individual configuration value from the nested
configuration structure, where ks is a sequence of keys.
Returns nil if the key is not present, or the default value if
supplied."))
```
Your service may then specify a dependency on the configuration service in order to access service configuration data.
Here's an example. Assume you have a directory called `conf.d`, and in it, you have a single config file called `foo.conf` with the following contents
```conf
foosection1{
foosetting1 = foo
foosetting2 = bar
}
```
Then, you can define a service like this:
```clj
(defservice foo-service
[[:ConfigService get-in-config]]
;; service initialization code
(init [this context]
(println
(format "foosetting2 has a value of '%s'"
(get-in-config [:foosection1 :foosetting2])))
context))
```
Then, if you add `foo-service` to your `bootstrap.cfg` file and launch your app with `--config ./conf.d`, during initialization of the `foo-service` you should see:
foosetting2 has a value of 'bar'
## Logging configuration
Trapperkeeper provides some automatic configuration for logging during application startup. This way, services don't have to deal with that independently, and all services running in the same Trapperkeeper container will be able to share a common logging configuration. The built-in logging configuration is compatible with `clojure.tools/logging`, so services can just call the `clojure.tools/logging` functions and logging will work out of the box.
The logging implementation is based on [`logback`](http://logback.qos.ch/). This means that Trapperkeeper will look for a `logback.xml` file on the classpath, but you can override the location of this file via configuration. This is done using the configuration setting `logging-config` in a `global` section of your configuration files.
`logback` is based on [`slf4j`](http://www.slf4j.org/), so it should be compatible with the built-in logging of just about any existing Java libraries that your project may depend on. For more information on configuring logback, have a look at [their documentation](http://logback.qos.ch/manual/configuration.html).
For example:
```CONF
global {
logging-config = /path/to/logback.xml
}
```
OpenVoxProject-trapperkeeper-49527b2/documentation/Built-in-Services.md 0000664 0000000 0000000 00000002253 15224541352 0026232 0 ustar 00root root 0000000 0000000 # Built-in Services
Trapperkeeper includes a handful of built-in services that are intended to remove some of the tedium of tasks that are common to most applications. There is a configuration service (which is responsible for loading the application configuration and exposing it as data to other services), a shutdown service (which provides some means for shutting down the container and allows other services to register shutdown hooks), and an optional nREPL service (which can be used to run an embedded REPL in your application, so that you can connect to it from a remote process while it is running).
There are some other basic services available that don't ship with the Trapperkeeper core, in order to keep the dependency tree to a minimum. Of particular interest is the [webserver service](https://github.com/puppetlabs/trapperkeeper-webserver-jetty9), which you can use to run clojure Ring applications or java servlets.
Detailed information about Trapperkeeper's built-in services can be found on the following pages:
- [Configuration Service](Built-in-Configuration-Service.md)
- [Shutdown Service](Built-in-Shutdown-Service.md)
- [nREPL Service](Built-in-nREPL-Service.md)
OpenVoxProject-trapperkeeper-49527b2/documentation/Built-in-Shutdown-Service.md 0000664 0000000 0000000 00000012441 15224541352 0027660 0 ustar 00root root 0000000 0000000 # Trapperkeeper's Built-in Shutdown Service
The shutdown service is built-in to Trapperkeeper and, like the [configuration service](Built-in-Configuration-Service.md), is always loaded. It has two main responsibilities:
* Listen for a shutdown signal to the process, and initiate shutdown of the application if one is received (via CTRL-C or TERM signal)
* Provide functions that can be used by other services to initiate a shutdown (either because of a normal application termination condition, or in the event of a fatal error)
## Shutdown Hooks
A service may implement the `stop` function from the `Lifecycle` protocol. If so, this function will be called during application shutdown. The shutdown hook for any given service is guaranteed to be called *before* the shutdown hook for any of the services that it depends on.
For example:
```clj
(defn bar-shutdown
[]
(log/info "bar-service shutting down!"))
(defservice bar-service
[[:FooService foo]]
;; service initialization code
(init [this context]
(log/info "bar-service initializing.")
context)
;; shutdown code
(stop [this context]
(bar-shutdown)
context))
```
Given this service definition, the `bar-shutdown` function would be called during shutdown of the Trapperkeeper container (during both a normal shutdown or an error shutdown). Because `bar-service` has a dependency on `foo-service`, Trapperkeeper would also guarantee that the `bar-shutdown` is called *prior to* the `stop` function for the `foo-service` (assuming `foo-service` provides one).
## Provided Shutdown Functions
The shutdown service provides two functions that can be injected into other services: `request-shutdown` and `shutdown-on-error`. Here's the protocol:
```clj
(defprotocol ShutdownService
(request-shutdown [this] "Asynchronously trigger normal shutdown")
(shutdown-on-error [this service-id f] [this service-id f on-error]
"Higher-order function to execute application logic and trigger shutdown in
the event of an exception"))
```
To use them, you may simply specify a dependency on them:
```clj
(defservice baz-service
[[:ShutdownService request-shutdown shutdown-on-error]]
;; ...
)
```
### `request-shutdown`
`request-shutdown` initiates a shutdown of the application container
which will, in turn, cause all registered shutdown hooks to be called.
It is asynchronous and will eventually cause the `run` function to
return.
It accepts an optional argument which can be used to provide a map
specifying a process exit status and final messages like this:
```clj
{:puppetlabs.trapperkepper.core/exit`
{:status 3
:messages [["Unexpected filesystem error ..." *err*]]}}
```
which will finally be thrown from `run` as an `ex-info` of `:kind`
`:puppetlabs.trapperkepper.core/exit` like this:
```clj
{:kind :puppetlabs.trapperkepper.core/exit`
:status 3
:messages [["Unexpected filesystem error ..." *err*]]}}
```
The `:messages` should include any desired newlines, and when relying
on `:puppetlabs.trapperkepper.core/main`, the `:messages` will be
printed and `exit` will be called with the given `:status`.
### `shutdown-on-error`
`shutdown-on-error` is a higher-order function that can be used as a wrapper around some logic in your services; its functionality is simple:
```clj
(try
; execute the given function
(catch Throwable t
; initiate Trapperkeeper's shutdown logic
```
This has two main use-cases:
* "worker" / background threads that your service may launch
* a section of code that needs to execute in a service function, in which any error is so problematic that the entire application should shut down
`shutdown-on-error` accepts either two or three arguments: `[service-id f]` or `[service-id f on-error-fn]`.
`service-id` is the id of your service; you can retrieve this via `(service-id this)` inside of any of your service function definitions.
`f` is a function containing whatever application logic you desire; this is the function that will be wrapped in `try/catch`. `on-error-fn` is an optional callback function that you can provide, which will be executed during error shutdown *if* an unhandled exception occurs during the execution of `f`. `on-error-fn` should take a single argument: `context`, which is the service context map (the same map that is used in the lifecycle functions).
Here's an example:
```clj
(defn my-work-fn
[]
;; do some work
(Thread/sleep 10000)
;; uh-oh! An unhandled exception!
(throw (IllegalStateException. "egads!")))
(defn my-error-cleanup-fn
[context]
(log/info "Something terrible happened! Foo: " (context :foo))
(log/info "Performing shutdown logic that should only happen on a fatal error."))
(defn my-normal-shutdown-fn
[]
(log/info "Performing normal shutdown logic."))
(defservice yet-another-service
[[:ShutdownService shutdown-on-error]]
(init [this context]
(assoc context
:worker-thread
(future (shutdown-on-error (service-id this) my-work-fn my-error-cleanup-fn))))
(stop [this context]
(my-normal-shutdown-fn)
context))
```
In this scenario, the application would run for 10 seconds, and then the fatal exception would be thrown. Trapperkeeper would then call `my-error-cleanup-fn`, and then attempt to call all of the normal shutdown hooks in the correct order (including `my-normal-shutdown-fn`).
OpenVoxProject-trapperkeeper-49527b2/documentation/Built-in-nREPL-Service.md 0000664 0000000 0000000 00000003231 15224541352 0026762 0 ustar 00root root 0000000 0000000 # Configuring the nREPL service
The `nREPL` service is intended to be used as a debugging tool and not directly called by any other application code, so no useful functions are directly exported by this service. A `shutdown` function is provided solely to allow the shutdown service to cleanly stop the `nREPL` server.
The `nrepl` section in a _Trapperkeeper_ configuration file specifies all the settings needed to start up an `nREPL` server attached to _Trapperkeeper_.
## `boostrap.cfg`
By default, the nrepl service is not put into your application's `bootstrap.cfg`. If you want to use this service, add
`puppetlabs.trapperkeeper.services.nrepl.nrepl-service/nrepl-service` to your `bootstrap.cfg` and enable it in your config.
## `enabled`
The `enabled` flag is a boolean value, which can be set to either `"true"` or `"false"`. When this is set to true, the `nREPL` server will start and accept connections. If this value is not specified then `enabled=false` is assumed.
## `host`
The IP address to bind the nREPL server to. If not specified then `0.0.0.0` is used, which indicates binding to all available interfaces.
## `port`
The port that the `nREPL` server is bound to. If no port is defined then the default value of `7888` is used.
## `middlewares`
A list of nREPL middlewares to load; for example, for compatibility with LightTable or other editors.
## Typical `config.conf` for nREPL
```conf
nrepl {
port = 12345
enabled = true
middlewares = [lighttable.nrepl.handler/lighttable-ops]
}
```
## The `nREPL` server
For more information on the nREPL server see [the nREPL server README](https://github.com/clojure/tools.nrepl/blob/master/README.md).
OpenVoxProject-trapperkeeper-49527b2/documentation/Command-Line-Arguments.md 0000664 0000000 0000000 00000021600 15224541352 0027171 0 ustar 00root root 0000000 0000000 # Command Line Arguments
Trapperkeeper's default mode of operation is to handle the processing of application command-line arguments for you. This is done for a few reasons:
* It needs some data for bootstrapping
* Since the idea is that you will be composing multiple services together in a Trapperkeeper instance, managing command line options across multiple services can be tricky; using the configuration service is easier
* Who wants to process command-line arguments, anyway?
Note that if you absolutely need control over the command line argument processing, it is possible to circumvent the built-in handling by calling Trapperkeeper's `bootstrap` function directly; see additional details in the [Bootstrapping](Bootstrapping.md) page.
Trapperkeeper supports four command-line arguments:
* `--config/-c`: The path to the configuration file or directory. This option is used to initialize the configuration service. This argument is optional; if not specified, Trapperkeeper will act as if you had given it an empty configuration file.
* `--bootstrap-config/-b`: This argument is optional; if specified, the value should be a path to a bootstrap configuration file, or a comma separated list of files and directories ([see below](#multiple-bootstrap-files)) that Trapperkeeper will use (instead of looking for `bootstrap.cfg` in the current working directory or on the classpath)
* `--debug/-d`: This option is not required; it's a flag, so it will evaluate to a boolean. If `true`, sets the logging level to DEBUG, and also sets the `:debug` key in the configuration map provided by the configuration-service.
* `--restart-file/-r`: This argument is optional; if specified, the value should be a path to a file containing a start counter. Trapperkeeper increments this counter after each time it has started all of the services in an application. See the [Restart File](Restart-File.md) page for additional details.
### Multiple bootstrap files
The `--bootstrap-config` argument can be used to specify multiple bootstrap files. This way, a Trapperkeeper app's bootstrap configuration can be split up into multiple locations. You might want to do this to separate logically related services into their own files for instance.
If multiple bootstrap files are specified, Trapperkeeper will treat them as if they have all been concatenated into a single bootstrap.cfg file and handle dependency resolution as normal.
Multiple bootstrap files are specified by giving the `--bootstrap-config` command line option a comma separated list of files and directories. For example:
```
--bootstrap-config ./first/path,/etc/second/path,./a/single/file.cfg
```
Each item in the list of paths can be one of:
* A path to a single config file
* A path to a directory of config files. Only files ending in .cfg will be used
* A path to a file inside of a jar. E.g. `jar:file:///usr/bin/myjar.jar!/bootstrap.cfg`
## `main` and Trapperkeeper
There are three different ways that you can initiate Trapperkeeper's bootstrapping process:
### Defer to Trapperkeeper's `main` function
In your Leiningen project file, you can simply specify Trapperkeeper's `main` as your `:main`:
:main puppetlabs.trapperkeeper.main
Then you can simply use `lein run --config ...` to launch your app, or `lein uberjar` to build an executable jar file that calls Trapperkeeper's `main`.
### Call Trapperkeeper's `main` function from your code
If you don't want to defer to Trapperkeeper as your `:main` namespace, you can simply call Trapperkeeper's `main` from your own code. All that you need to do is to pass along the command line arguments, which Trapperkeeper needs for initializing bootstrapping, configuration, etc. Here's what that might look like:
```clj
(ns foo
(:require [puppetlabs.trapperkeeper.core :as trapperkeeper]))
(defn -main
[& args]
;; ... any code you like goes here
(apply trapperkeeper/main args))
```
Trapperkeeper's `main` will call `exit` itself in some cases,
e.g. after argument processing errors, `--help` requests, or calls to
`request-shutdown` that specify a specific process exit status.
### Call Trapperkeeper's `run` function directly
If your application needs to handle command line arguments directly, rather than allowing Trapperkeeper to handle them, you can circumvent Trapperkeeper's `main` function and call `run` directly.
*NOTE* that if you intend to write multiple services and load them into the same Trapperkeeper instance, it can end up being tricky to deal with varying sets of command line options that are supported by the different services. For this reason, it is generally preferable to configure the services via the configuration files and not rely on command-line arguments.
But, if you absolutely must... Here's how it can be done:
```clj
(ns foo
(:require [puppetlabs.trapperkeeper.core :as trapperkeeper]))
(defn -main
[& args]
(let [my-processed-cli-args (process-cli-args args)
trapperkeeper-options {:config (my-processed-cli-args :config-file-path)
:bootstrap-config nil
:debug false}]
;; ... other app initialization code
(trapperkeeper/run trapperkeeper-options)))
```
Note that Trapperkeeper's `run` function requires a map as an argument, and this map must contain the `:config` key which Trapperkeeper will use just as it would have used the `--config` value from the command line. You may also (optionally) provide `:bootstrap-config` and `:debug` keys, to override the path to the bootstrap configuration file and/or enable debugging on the application.
If shutdown is initiatiated by a call to `request-shutdown` asking for
a specific exit status, `run` will throw an ex-info exception with a
`:kind` of `puppetlabs.trapperkeeper.core/exit`. See the
`request-shutdown` documentation for additional information.
### Other Ways to Boot
We use the term `boot` to describe the process of building up an instance of a `TrapperkeeperApp`, and then calling `init` and `start` on all of its services in the correct order.
It is possible to use the Trapperkeeper framework at a slightly lower level. Using `run` or `main` will boot all of the services and then block the main thread until a shutdown is triggered; if you need more control, you'll be getting a reference to a `TrapperkeeperApp` directly.
#### `TrapperkeeperApp` protocol
There is a protocol that represents a Trapperkeeper application:
```clj
(defprotocol TrapperkeeperApp
"Functions available on a Trapperkeeper application instance"
(app-context [this] "Returns the application context for this app (an atom containing a map)")
(check-for-errors! [this] (str "Check for any errors which have occurred in "
"the bootstrap process. If any have "
"occurred, throw a `java.lang.Throwable` with "
"the contents of the error. If none have "
"occurred, return the input parameter.")
(init [this] "Initialize the services")
(start [this] "Start the services")
(stop [this] "Stop the services"))
```
With a reference to a `TrapperkeeperApp`, you can gain more control over when the lifecycle functions are called. To get an instance, you can call any of these functions:
* `(boot-with-cli-data [cli-data])`: this function expects you to process your own command-line arguments into a map (as with `run`). It then creates a TrapperkeeperApp, boots all of the services, and returns the app.
* `(boot-services-with-cli-data [services cli-data])`: this function expects you to process your own command-line arguments into a map, and also to build up your own list of services to pass in as the first argument. It circumvents the normal Trapperkeeper `bootstrap.cfg` process, creates a `TrapperkeeperApp` with all of your services, boots them, and returns the app.
* `(boot-services-with-config [services config])`: this function expects you to process your own command-line arguments, configuration data, and build up your own list of services. You pass it the list of services and the map of all service configuration data, and it circumvents the normal `bootstrap.cfg` process, creates a `TrapperkeeperApp` with all of your services, boots them, and returns the app.
Each of the above gives you a way to get a reference to a `TrapperkeeperApp` without blocking the main thread to wait for shutdown. If, later, you do wish to wait for the shutdown, you can simply call `run-app` and pass it your `TrapperkeeperApp`. Alternately, you can call `stop` on the `TrapperkeeperApp` to initiate shutdown on your own terms.
Note that all of these functions *do* boot your services. If you wish to have more control over the booting of the services, you can use this function:
* `(build-app [services config-data])`: this function creates a `TrapperkeeperApp` *without* booting the services. You can then boot them yourself by calling `init` and `start` on the `TrapperkeeperApp`.

The `nREPL` service is intended to be used as a debugging tool and not directly called by any other application code. So no useful functions are directly exported by this service. A `shutdown` function is provided solely to allow the shutdown service to cleanly stop the `nREPL` server.
The `[nrepl]` section in a _Trapperkeeper_ `.ini` configuration file specifies all the settings needed to start up an `nREPL` server attached to _Trapperkeeper_.
## `enabled`
The `enabled` flag is a boolean value, which can be set to either `"true"` or `"false"`. When this is set to true, the `nREPL` server will start and accept connections. If this value is not specified then `enabled=false` is assumed.
## `host`
The IP address to bind the nREPL server to. If not specified then `0.0.0.0` is used, which indicates binding to all available interfaces.
## `port`
The port that the `nREPL` server is bound to. If no port is defined then the default value of `7888` is used.
## `middlewares`
A list of nREPL middlewares to load; for example, for compatibility with LightTable or other editors.
## Typical `config.ini` for nREPL
```ini
[nrepl]
port = 12345
enabled = true
middlewares = [lighttable.nrepl.handler/lighttable-ops]
```
## The `nREPL` server
For more information on the nREPL server, see [the tools.nrepl README](https://github.com/clojure/tools.nrepl/blob/master/README.md).
OpenVoxProject-trapperkeeper-49527b2/documentation/Defining-Services.md 0000664 0000000 0000000 00000020256 15224541352 0026275 0 ustar 00root root 0000000 0000000 # Defining Services
Trapperkeeper provides two constructs for defining services: `defservice` and `service`. As you might expect, `defservice` defines a service as a var in your namespace, and `service` allows you to create one inline and assign it to a variable in a let block or other location. Here's how they work:
## `defservice`
`defservice` takes the following arguments:
* a service name
* an optional doc string
* an optional service protocol; only required if your service exports functions that can be used by other services
* a dependency list indicating other services/functions that this service requires
* a series of function implementations. This must include all of the functions in the protocol if one is specified, and may also optionally provide override implementations for the built-in service `Lifecycle` functions.
### Service Lifecycle
The service `Lifecycle` protocol looks like this:
```clj
(defprotocol Lifecycle
(init [this context])
(start [this context])
(stop [this context]))
```
(This may look familiar; we chose to use the same function names as some of the existing lifecycle protocols. Ultimately we'd like to just use one of those protocols directly, but for now our needs are different enough to warrant avoiding the introduction of a dependency on an existing project.)
All service lifecycle functions are passed a service `context` map, which may be used to store any service-specific state (e.g., a database connection pool or some other object that you need to reference in subsequent functions.) Services may define these functions, `assoc` data into the map as needed, and then return the updated context map. The updated context map will be maintained by the framework and passed to subsequent lifecycle functions for the service.
The default implementation of the lifecycle functions is to simply return the service context map unmodified; if you don't need to implement a particular lifecycle function for your service, you can simply omit it and the default will be used.
Trapperkeeper will call the lifecycle functions in order based on the dependency list of the services; in other words, if your service has a dependency on service `Foo`, you are guaranteed that `Foo`'s `init` function will be called prior to yours, and that your `stop` function will be called prior to `Foo`'s.
### Example Service
Let's look at a concrete example:
```clj
;; This is the list of functions that the `FooService` must implement, and which
;; are available to other services who have a dependency on `FooService`.
(defprotocol FooService
(foo1 [this x])
(foo2 [this])
(foo3 [this x]))
(defservice foo-service
;; docstring (optional)
"A service that foos."
;; now we specify the (optional) protocol that this service satisfies:
FooService
;; the :depends value should be a vector of vectors. Each of the inner vectors
;; should begin with a keyword that matches the protocol name of another service,
;; which may be followed by any number of symbols. Each symbol is the name of a
;; function that is provided by that service. Trapperkeeper will fail fast at
;; startup if any of the specified dependency services do not exist, *or* if they
;; do not provide all of the functions specified in your vector. (Note that
;; the syntax used here is actually just the
;; [fnk binding syntax from the Plumatic plumbing library](https://github.com/plumatic/plumbing/tree/master/src/plumbing/fnk#fnk-syntax),
;; so you can technically use any form that is compatible with that.)
[[:SomeService function1 function2]
[:AnotherService function3 function4]]
;; After your dependencies list comes the function implementations.
;; You must implement all of the protocol functions (if a protocol is
;; specified), and you may also override any `Lifecycle` functions that
;; you choose. We'll start by implementing the `init` function from
;; the `Lifecycle`:
(init [this context]
;; do some initialization
;; ...
;; now return the service context map; we can update it to include
;; some state if we like. Note that we can use the functions that
;; were specified in our dependency list here:
(assoc context :foo (str "Some interesting state:" (function1)))
;; We could optionally also override the `start` and `stop` lifecycle
;; functions, but we won't for this example.
;; Now we'll define our service function implementations. Again, we are
;; free to use the imported functions from the other services here:
(foo1 [this x] ((comp function2 function3) x))
(foo2 [this] (println "Function4 returns" (function4)))
;; We can also access the service context that we updated during the
;; lifecycle functions, by using the `service-context` function from
;; the `Service` protocol:
(foo3 [this x]
(let [context (service-context this)]
(format "x + :foo is: '%s'" (str x (:foo context))))))
```
After this `defservice` statement, you will have a var named `foo-service` in your namespace that contains the service. You can reference this from a Trapperkeeper bootstrap configuration file to include that service in your app, and once you've done that your new service can be referenced as a dependency (`{:depends [[:FooService ...`) by other services.
### Multi-arity Protocol Functions
Clojure's protocols allow you to define multi-arity functions:
```clj
(defprotocol MultiArityService
(foo [this x] [this x y]))
```
Trapperkeeper services can use the syntax from clojure's `reify` to implement these multi-arity functions:
```clj
(defservice my-service
MultiArityService
[]
(foo [this x] x)
(foo [this x y] (+ x y)))
```
## `service`
`service` works very similarly to `defservice`, but it doesn't define a var in your namespace; it simply returns the service instance. Here are some examples (with and without protocols):
```clj
(service
[]
(init [this context]
(println "Starting anonymous service!")
context))
(defprotocol AnotherService
(foo [this]))
```
## Optional Services
_Introduced in Trapperkeeper 1.2.0_
When defining a service, it is possible to mark certain other services your service depends on as being optional. This is useful, for example, when composing your service against services that you might not need during development or for certain deployment scenarios. You can write the same code whether or not an optional service has been included in your bootstrap.cfg or not.
To mark a dependency as optional, you use a different form to specify your dependencies:
```clj
(defprotocol HaikuService
(get-haiku [this] "return a lovely haiku"))
(defprotocol SonnetService
(get-sonnet [this] "return a lovely sonnet"))
;; ... snip the definitions of HaikuService and SonnetService ...
(defservice poetry-service
PoetryService
{:required [HaikuService]
:optional [SonnetService]}
(haiku [this]
(get-haiku HaikuService))
(sonnet [this]
(if-let [sonnet-svc (tk-svc/maybe-get-service this :SonnetService)]
(get-sonnet sonnet-svc)
"insert moving sonnet here"))
```
In the above example, we use a map of the form `{:required [...] :optional [...]}` to split up our required and optional dependencies. When we run this service in TK, our code will call `(get-sonnet)` if an implementation of `SonnetService` has been included in the `bootstrap.cfg`. Otherwise, we'll return the placeholder string `"insert moving sonnet here"`.
**Warning** Because of a [limitation](https://github.com/plumatic/plumbing/issues/114) in Plumatic Schema, you can't use the destructuring `[:SonnetService get-sonnet]` syntax when declaring optional dependencies.
The `Service` protocol has two helpers to make it easier to work with optional dependencies:
* `(maybe-get-service [this service-id])` which takes a keyword service ID and returns the service, if included, or nil
* `(service-included? [this service-id])` which takes a keyword service ID and returns true or false based on its inclusion.
These helpers live alongside the other service helpers like `get-service` in `puppetlabs.trapperkeeper.services`.

## Errors During `init` or `start`
If the `init` or `start` function of any service throws a `Throwable`, it will cause Trapperkeeper to shut down. No further `init` or `start` functions of any services will be called after the first `Throwable` is thrown. If you are using Trapperkeeper's `main` function, all service `stop` functions will be called before the process terminates. The `stop` functions are called in order to give each service a chance to clean up any resources which may have only been partially initialized before the `Throwable` was thrown -- e.g., allowing any worker threads which may have been spawned to be gracefully shut down so that the process can terminate. Service `stop` functions must be designed such that they could be executed with no adverse effects even if called before the service's `init` and `start` functions could successfully complete.
If the `init` or `start` function of your service launches a background thread to perform some costly initialization computations (like, say, populating a pool of objects which are expensive to create), it is advisable to wrap that computation inside a call to `shutdown-on-error`; however, you should note that `shutdown-on-error` does *not* short-circuit Trapperkeeper's start-up sequence - the app will continue booting. The `init` and `start` functions of all services will still be run, and once that has completed, all `stop` functions will be called, and the process will terminate.
## Services Should Fail Fast
Trapperkeeper embraces fail-fast behavior. With that in mind, we advise writing services that also fail-fast. In particular, if your service needs to spin-off a background thread to perform some expensive initialization logic, it is a best practice to push as much code as possible outside of the background thread (for example, validating configuration data), because `Throwables` on the main thread will propagate out of `init` or `start` and cause the application to shut down - i.e., it will *fail fast*. There are different operational semantics for errors thrown on a background thread (see previous section).

There's nothing really special about developing a Trapperkeeper application as compared to any other Clojure application, but there are a couple of things we've found useful:
### Leiningen's `checkouts` feature
Since Trapperkeeper is intended to help modularize applications, it also increases the likelihood that you'll end up working with more than one code base/git repo at the same time. When you find yourself in this situation, Leiningen's [checkouts](http://jakemccrary.com/blog/2012/03/28/working-on-multiple-clojure-projects-at-once/) feature is very useful.
### Leiningen's `trampoline` feature
If you need to test the shutdown behavior of your application, you may find yourself trying to do `lein run` and then sending a CTRL-C or `kill`. However, due to the way Leiningen manages JVM processes, this CTRL-C will be handled by the lein process and won't actually make it to Trapperkeeper. If you need to test shutdown functionality, you'll want to use `lein trampoline run`.
However, one quirk that we've discovered is that it does not appear that lein's `checkouts` and `trampoline` features work together; thus, when you run the app via `lein trampoline`, the classpath will not include the projects in the `checkouts` directory. Thus, you'll need to do `lein install` on the `checkouts` projects to copy their jars into your `.m2` directory before running `lein trampoline run`.

Trapperkeeper is a Clojure framework for hosting long-running applications and services. You can think of it as a "binder", of sorts--for Ring applications and other modular bits of Clojure code.
It ties together a few nice patterns we've come across in the clojure community:
* Stuart Sierra's ["reloaded" workflow](http://thinkrelevance.com/blog/2013/06/04/clojure-workflow-reloaded)
* Component lifecycles (["Component"](https://github.com/stuartsierra/component), ["jig"](https://github.com/juxt/jig#components))
* [Composable services](http://plumatic.github.io/graph-abstractions-for-structured-computation/) (based on the excellent [Plumamatic graph library](https://github.com/plumatic/plumbing))
We also had a few other needs that Trapperkeeper addresses (some of these arise because of the fact that we at Puppet Labs are shipping on-premises software, rather than SaaS. The framework is a shipping part of the application, in addition to providing useful features for development):
* Well-defined service interfaces (using clojure protocols)
* Ability to turn services on and off via configuration after deploy
* Ability to swap service implementations via configuration after deploy
* Ability to load multiple web apps (usually Ring) into a single webserver
* Unified initialization of logging and configuration so services don't have to concern themselves with the implementation details
* Super-simple configuration syntax
A "service" in Trapperkeeper is represented as simply a map of clojure functions. Each service can advertise the functions that it provides via a protocol, as well as list other services that it has a dependency on. You then configure Trapperkeeper with a list of services to run and launch it. At startup, it validates that all of the dependencies are met and fails fast if they are not. If they are, then it injects the dependency functions into each service and starts them all up in the correct order.
Trapperkeeper provides a few built-in services such as a configuration service, a shutdown service, and an nREPL service. Other services (such as a web server service) are available and ready to use, but don't ship with the base framework. Your custom services can specify dependencies on these and leverage the functions that they provide. For more details, see the [Built-in Services](Built-in-Services.md) page.
# Credits and Origins
Most of the heavy-lifting of the Trapperkeeper framework is handled by the excellent [Plumatic Graph](https://github.com/plumatic/plumbing) library. To a large degree, Trapperkeeper just wraps some basic conventions and convenience functions around that library, so many thanks go out to the fine folks at Plumatic for sharing their code!
Trapperkeeper borrows some of the most basic concepts of the OSGi "service registry" to allow users to create simple "services" and bind them together in a single container, but it doesn't attempt to do any fancy classloading magic, hot-swapping of code at runtime, or any of the other things that can make OSGi and other similar application frameworks complex to work with.
# Hopes and Dreams
Here are some ideas that we've had and things we've played around with a bit for improving Trapperkeeper in the future.
## More flexible configuration service
The current configuration service is hard-coded to use files (`.ini`, `.edn`, `.conf`, `.json`, or `.properties`) as its back end and is hard-coded to use `logback` to initialize logging. We'd like to make all of those more flexible; e.g., to support other persistence mechanisms, perhaps allow dynamic modifications to configuration values, support other logging frameworks, etc. These changes will probably require us to make the service life cycle just a bit more complex, though, so we didn't tackle them for the initial releases.
## Alternate implementations of the webserver service
We currently provide both a [Jetty 7](https://github.com/puppetlabs/trapperkeeper-webserver-jetty7) and a [Jetty 9](https://github.com/puppetlabs/trapperkeeper-webserver-jetty9) implementation of the web server service. We may also experiment with some other options such as Netty.
## Add support for other types of web applications
The current `:webserver-service` interface provides functions for registering a [Ring](https://github.com/ring-clojure/ring) or [Servlet](http://docs.oracle.com/javaee/7/api/javax/servlet/Servlet.html) application. We'd like to add a few more similar functions that would allow you to register other types of web applications, specifically an `add-rack-handler` function that would allow you to register a Rack application (to be run via JRuby).
OpenVoxProject-trapperkeeper-49527b2/documentation/Plugin-System.md 0000664 0000000 0000000 00000002303 15224541352 0025502 0 ustar 00root root 0000000 0000000 # Experimental Plugin System
Trapperkeeper has an **extremely** simple, experimental plugin mechanism. It allows you to specify (as a command-line argument) a directory of "plugin" .jars that will be dynamically added to the classpath at runtime. Each jar file will also be checked for duplicate classes or namespaces before it is added, so as to prevent any unexpected behavior.
This provides the ability to extend the functionality of a deployed, Trapperkeeper-based application by simply including one or more services packaged into standalone "plugin" jar files, and adding the additional service(s) to the bootstrap configuration.
Projects that wish to package themselves as "plugin" jar files should build an uberjar containing all of their dependencies. However, there is one caveat here - Trapperkeeper *and all of its dependencies* should be excluded from the uberjar. If the exclusions are not defined correctly, Trapperkeeper will fail to start because there will be duplicate versions of classes/namespaces on the classpath.
Plugins are specified via a command-line argument: `--plugins /path/to/plugins/directory`; every .jar file in that directory will be added to the classpath by Trapperkeeper.
OpenVoxProject-trapperkeeper-49527b2/documentation/Polyglot-Support.md 0000664 0000000 0000000 00000002573 15224541352 0026256 0 ustar 00root root 0000000 0000000 # Polyglot Support
It should be possible (when extenuating circumstances necessitate it) to integrate code from just about any JVM language into a Trapperkeeper application. At the time of this writing, the only languages we've really experimented with are Java and Ruby (via JRuby).
For Java, the Trapperkeeper webserver service contains an [example servlet app](https://github.com/puppetlabs/trapperkeeper-webserver-jetty9/tree/master/examples/servlet_app), which illustrates how you can run a Java servlet in trapperkeeper's webserver.
We have also included a simple example of wrapping a Java library in a Trapperkeeper service, so that it can provide functions to other services. Have a look at the code for the [example Java service provider app](https://github.com/puppetlabs/trapperkeeper/tree/master/examples/java_service) for more info.
For Ruby, we've been able to write an alternate implementation of a `webserver-service` which provides an `add-rack-handler` function for running Rack applications inside of Trapperkeeper. We've also been able to illustrate the ability to call clojure functions provided by existing clojure Trapperkeeper services from the Ruby code in such a Rack application. This code isn't necessarily production quality yet, but if you're interested, have a look at the [trapperkeeper-ruby project on github](https://github.com/puppetlabs/trapperkeeper-ruby).
OpenVoxProject-trapperkeeper-49527b2/documentation/Referencing-Services.md 0000664 0000000 0000000 00000006066 15224541352 0027004 0 ustar 00root root 0000000 0000000 # Referencing Services
One of the most important features of Trapperkeeper is the ability to specify dependencies between services, and, thus, to reference functions provided by one service from functions in another service. Trapperkeeper actually exposes several different ways to reference such functions, since the use cases may vary a great deal depending on the particular services involved.
## Individual Functions
In the simplest case, you may just want to grab a direct reference to one or more individual functions from another service. That can be accomplished like this:
```clj
(defservice foo-service
[[:BarService bar-fn]
[:BazService baz-fn]]
(init [this context]
(bar-fn)
(baz-fn)
context))
```
This form expresses a dependency on two other services; one implementing the `BarService` protocol, and one implementing the `BazService` protocol. It gives us a direct reference to the functions `bar-fn` and `baz-fn`. You can call them as normal functions, without worrying about protocols any further.
## A Map of Functions
If you want to get simple references to plain-old functions from a service (again, without worrying about the protocols), but you don't want to have to list them all out explicitly in the binding form, you can do this:
```clj
(defservice foo-service
[BarService BazService]
(init [this context]
((:bar-fn BarService))
((:baz-fn BazService))
context))
```
With this syntax, what you get access to are two local vars `BarService` and `BazService`, the value of each of which is a map. The map keys are all keyword versions of the function names for all of the functions provided by the service protocol, and the values are the plain-old functions that you can just call directly.
## Plumatic Graph Binding Form
Both of the cases above are actually just specific examples of forms supported by the underlying Plumatic Graph library that we are using to manage dependencies. If you're interested, the plumatic library offers some other ways to specify the binding forms and access your dependencies. For more info, see the [fnk binding syntax from the Plumatic plumbing library](https://github.com/plumatic/plumbing/tree/master/src/plumbing/fnk#fnk-syntax).
## Via Service Protocol
In some cases you may actually prefer to get a reference to an object that satisfies the service protocol. This way, you can pass the object around and use the actual clojure protocol to reference the functions provided by a service. To achieve this, you use the `get-service` function from the main `Service` protocol. Here's how this might look:
```clj
(ns bar.service)
(defprotocol BarService
(bar-fn [this]))
...
(ns foo.service
(:require [bar.service :as bar]))
(defservice foo-service
;; This dependency is only here to enforce that the BarService gets loaded
;; before this service does; we won't need to refer to the `BarService` var
;; anywhere in this service definition.
[BarService]
(init [this context]
(let [bar-service (get-service this :BarService)]
(bar/bar-fn bar-service))
context))
```

[Stuart Sierra's "reloaded" workflow](http://thinkrelevance.com/blog/2013/06/04/clojure-workflow-reloaded) has become very popular in the clojure world of late; and for good reason, it's an awesome and super-productive way to do interactive development in the REPL, and it also helps encourage code modularity and minimizing mutable state. He has some [example code](https://github.com/stuartsierra/component#reloading) that shows some utility functions to use in the REPL to interact with your application.
Trapperkeeper was designed with this pattern in mind as a goal. Thus, it's entirely possible to write some very similar code that allows you to start/stop/reload your app in a REPL:
```clj
(ns examples.my-app.repl
(:require [puppetlabs.trapperkeeper.services.webserver.jetty9-service
:refer [jetty9-service]]
[examples.my-app.services
:refer [count-service foo-service baz-service]]
[puppetlabs.trapperkeeper.core :as tk]
[puppetlabs.trapperkeeper.app :as tka]
[clojure.tools.namespace.repl :refer (refresh)]))
;; a var to hold the main `TrapperkeeperApp` instance.
(def system nil)
(defn init []
(alter-var-root #'system
(fn [_] (tk/build-app
[jetty9-service
count-service
foo-service
baz-service]
{:global
{:logging-config "examples/my_app/logback.xml"}
:webserver {:port 8080}
:example {:my-app-config-value "FOO"}})))
(alter-var-root #'system tka/init)
(tka/check-for-errors! system))
(defn start []
(alter-var-root #'system
(fn [s] (if s (tka/start s))))
(tka/check-for-errors! system))
(defn stop []
(alter-var-root #'system
(fn [s] (when s (tka/stop s)))))
(defn go []
(init)
(start))
(defn context []
@(tka/app-context system))
;; pretty print the entire application context
(defn print-context []
(clojure.pprint/pprint (context)))
(defn reset []
(stop)
(refresh :after 'examples.my-app.repl/go))
```
For a working example, see the `repl` namespace in the [jetty9 example app](https://github.com/puppetlabs/trapperkeeper-webserver-jetty9/tree/master/examples/ring_app).

When using Trapperkeeper apps inside of packages, it is convenient for a service
framework to have a clear indication as to when all of the Trapperkeeper
services in the app have been started -- as opposed to just knowing when the
Java process hosting the app has been spawned. The "restart file" feature in
Trapperkeeper provides this capability. As a reference example, the
[EZBake](https://github.com/puppetlabs/ezbake) build system for
Trapperkeeper-based applications makes use of the "restart file" feature. Its
service packages can pause a hosting service framework (SysVinit, systemd)
during a "service start" attempt until the app's services have all been started,
or have failed to start.
The "restart file" is considered to be a somewhat experimental feature in that
the implementation may change in a future release.
## Implementation Details
Each time Trapperkeeper has successfully finished processing all of the start
calls that it makes to each of the services in an application -- both at Java
process start and after a service reload is requested -- it increments a
counter in a file on disk. The location of the file is controlled by the value
of the `restart-file` setting.
If the value in the file before services are started is '3', for example, the
value will be updated to '4' after services have been started. If the file does
not exist at the time services have been started, the value is written as '1'.
The value rolls back around to '1' if the value would be incremented beyond the
maximum value for a `java.lang.Long` or if the contents of the file is otherwise
unable to be parsed as an integer.
In terms of using the restart file as an indication that services have been
started -- for example, from a background script that accesses the file in a
polling loop to determine when the start phase has finished -- it is best to
just look for a change to the contents of the file rather than having any
specific logic that interprets the integer values. As noted earlier, the
nature of the 'start' marker may change in a future release.
## Configuration Details
The `restart-file` setting can be specified either via a command line argument
to Trapperkeeper...
```
-r | --restart-file /write/file/here
```
... or as a setting under the "global" section of a Trapperkeeper configuration
file. For example, a HOCON-formatted "global.conf" might have:
```
global: {
restart-file: /write/file/here
}
```
In the event that the `restart-file` setting were specified both as a command
line argument and within the "global" section of a Trapperkeeper configuration
file, the value specified on the command line would be the one in which the
'start' counter is incremented.
If a value for the `restart-file` setting is not specified via either the
command line or within the "global" section of a Trapperkeeper configuration
file, Trapperkeeper will not write a 'start' counter to any file.
OpenVoxProject-trapperkeeper-49527b2/documentation/Service-Interfaces.md 0000664 0000000 0000000 00000007074 15224541352 0026455 0 ustar 00root root 0000000 0000000 ## Service Interfaces
One of the goals of Trapperkeeper's "service" model is that a service should be thought of as simply an interface; any given service provides a protocol as its "contract", and the implementation details of these functions are not important to consumers. (This borrows heavily from OSGi's concept of a "service".) This means that you can write multiple implementations of a given service and swap them in and out of your application by simply modifying your configuration, without having to change any of the consuming code. The Trapperkeeper `webserver` service is an example of this pattern; we provide both a [Jetty 7 webserver service](https://github.com/puppetlabs/trapperkeeper-webserver-jetty7) and a [Jetty 9 webserver service](https://github.com/puppetlabs/trapperkeeper-webserver-jetty9) that can be used interchangeably.
One of the motivations behind this approach is to make it easier to ship "on-premise" or "shrink-wrapped" software written in Clojure. In SaaS environments, the developers and administrators have tight control over what components are used in an application, and can afford to be fairly rigid about how things are deployed. For on-premise software, the end user may need to have a great deal more control over how components are mixed and matched to provide a solution that scales to meet their needs; for example, a small shop may be able to run 10 services on a single machine without approaching the load capacity of the hardware, but a slightly larger shop might need to separate those services out onto multiple machines. Trapperkeeper provides an easy way to do this at packaging time or configuration time, and the administrator does not necessarily have to be familiar with clojure or EDN in order to effectively configure their system.
Here's a concrete example of how this might work:
```clj
(ns services.foo)
(defprotocol FooService
(foo [this]))
(ns services.foo.lowercase-foo
(:require [services.foo :refer [FooService])
(defservice foo-service
"A lower-case implementation of the `foo-service`"
FooService
[]
(foo [this] "foo"))
(ns services.foo.uppercase-foo
(:require [services.foo :refer [FooService]))
(defservice foo-service
"An upper-case implementation of the `foo-service`"
FooService
[]
(foo [this] "FOO"))
(ns services.foo-consumer)
(defprotocol FooConsumer
(bar [this]))
(defservice foo-consumer
"A service that consumes the `foo-service`"
FooConsumer
[[:FooService foo]]
(bar [this]
(format "Foo service returned: '%s'" (foo))))
```
Given this combination of services, you might have a `bootstrap.cfg` file that looks like:
services.foo-consumer/foo-consumer
services.foo.lowercase-foo/foo-service
If you then ran your app, calling the function `bar` provided by the `foo-consumer` service would yield: `"Foo service returned 'foo'"`. If you then modified your `bootstrap.cfg` file to look like:
services.foo-consumer/foo-consumer
services.foo.uppercase-foo/foo-service
Then the `bar` function would return `"Foo service returned 'bar'"`. This allows you to swap out a service implementation without making any code changes; you need only modify your `bootstrap.cfg` file.
This is obviously a trivial example, but the same approach could be used to swap out the implementation of something more interesting; a webserver, a message queue, a persistence layer, etc. This also has the added benefit of helping to keep code more modular; a downstream service should only interact with a service that it depends on through a well-known interface.

Trapperkeeper provides some [utility code](https://github.com/puppetlabs/trapperkeeper/tree/master/test/puppetlabs/trapperkeeper/testutils) for use in tests. The code is available in a separate "test" jar that you may depend
on by using a classifier in your project dependencies.
```clojure
(defproject yourproject "1.0.0"
...
:profiles {:dev {:dependencies [[puppetlabs/trapperkeeper "x.y.z" :classifier "test"]]}})
```
## Logging
The
[logging namespace](https://github.com/puppetlabs/trapperkeeper/tree/master/test/puppetlabs/trapperkeeper/testutils/logging.clj)
provides utilities to help capture and validate logging behavior.
### `with-test-logging`
This form provides one of the simplest, though least discriminating
ways to examine the log events produced by a body of code. All log
events generated by the "root" logger from within the form (typically
all events) will be available for inspection by the `logged?`
predicate:
```clojure
(with-test-logging
(log/info "hello log")
(is (logged? #"^hello log$"))
(is (logged? #"^hello log$" :info)))
```
Here `(log/info "hello log")` generates an info level log event with a
message of "hello log", and then `logged?` checks for it, first by
matching the message, and then by matching both the message and the
level.
### `logged?`
`logged?` must be called from within a `with-test-logging` form, and
returns true if any events that match its arguments have been logged
since the beginning of the form.
See the `logged?` docstring for a complete description, but as an
example, if the first argument is a regex pattern (typically generated
via Clojure's `#"pattern"`), then `logged?` will return true if the
pattern matches a single message of anything that has been logged since the
beginning of the enclosing `with-test-logging` form. An optional
second parameter restricts the match to log events with the specified
level: `:trace`, `:debug`, `:info`, `:warn`, `:error` or `:fatal`.
Note: by default `logged?` returns true only if there is exactly one
log line match. An optional third parameter can be specified to disable
this restriction.
### `event->map`
This function converts a LogEvent to a Clojure map of the kind
generated by `with-logged-event-maps` and `with-logger-event-maps`. A
log event produced by `(log/info "hello log")` would be converted to
this:
```clojure
{:message "hello log"
:level :info
:exception nil
:logger "the.namespace.containing.the.log.info.call"}
```
### `with-logged-event-maps`
This form provides more control than `with-test-logging` by appending
an `event->map` map to a collection for each log event produced within
its body, and the collection can be accessed though an atom bound to a
caller-specified name. For example, the `with-test-logging` based
tests above could be rewritten like this:
```clojure
(with-logged-event-maps events
(log/info "hello log")
(is (some #(re-matches #"hello log" (:message %)) @events))
(is (some #(and (re-matches #"hello log" (:message %))
(= :info (:message %)))
@events)))
```
A call to `(with-logged-event-maps ...)` is effectively the same as
`(with-logger-event-maps root-logger-name ...)`.
### `with-logger-event-maps`
This form is identical to `with-logged-event-maps` except that it
allows the specification of the `logger-id` from which events should
be captured; `with-logged-event-maps` always captures events from
`root-logger-name`.
## Testing Services
For the most part, we recommend that Trapperkeeper service definitions be written as thin wrappers around plain old functions. This means that the vast majority of your tests can be written as unit tests that operate on those functions directly.
However, it can be useful to have a few tests that actually boot up a Trapperkeeper application instance; this allows you to, for example, verify that the services that you have a dependency on get injected correctly.
To this end, the `puppetlabs.trapperkeeper.testutils.bootstrap` namespace includes some helper functions and macros for creating a Trapperkeeper application. The macros should be preferred in most cases; they generally start with the prefix `with-app-`, and allow you to create a temporary Trapperkeeper app given a list of services. They will take care of some important mechanics for you:
* Making sure that no JVM shutdown hooks are registered during tests, as they would be during a normal Trapperkeeper application boot sequence
* Making sure that the app is shut down properly after the test completes.
Here are some of the most useful ones:
### `with-app-with-config`
This macro allows you to specify the services you want to launch directly and to pass in a map of configuration data that the app should use. The services specified must include all dependencies and transitive dependencies needed to start each service; that is, what you'd normally put in the bootstrap.cfg.
```clj
(ns services.test-service-1)
(defprotocol TestService1
(test-fn [this]))
(defservice test-service1
TestService1
[]
(test-fn [this] "foo"))
```
```clj
(ns services.test-service2)
(defservice test-service2
;;...
)
```
```clj
(ns test.services-test
(:require services.test-service-1 :as t1))
(with-app-with-config app
[test-service1 test-service2]
{:myconfig {:foo "foo"
:bar "bar"}}
(let [test-svc (get-service app :TestService1)]
(is (= "baz" (t1/test-fn test-svc))))
```
### `with-app-with-cli-data`
This variant is very similar, but instead of passing a map of config data, you pass a map of parsed command-line arguments, such as the path to a config file on disk that should be processed to build the actual application configuration:
```clj
(with-app-with-cli-data app
[test-service1 test-service2]
{:config "./dev-resources/config.conf"}
(let [test-svc (get-service app :TestService1)]
(is (= "baz" (t1/test-fn test-svc))))
```
### `with-app-with-cli-args`
This version accepts a vector of command-line arguments:
```clj
(with-app-with-cli-args app
[test-service1 test-service2]
["--config" "./dev-resources/config.conf" "--debug"]
(let [test-svc (get-service app :TestService1)]
(is (= "baz" (t1/test-fn test-svc))))
```
### `with-app-with-empty-config`
This version is useful when you don't need to pass in any configuration data at all to the services:
```clj
(with-app-with-empty-config app
[test-service1 test-service2]
(let [test-svc (get-service app :TestService1)]
(is (= "baz" (t1/test-fn test-svc))))
```
For each of the above macros, there is generally a `bootstrap-services-with-*` function that will behave similarly; however, the `bootstrap-*` functions don't handle the cleanup/shutdown behaviors for you, so they should only be used in rare cases.

This page provides some general guidelines for writing Trapperkeeper services.
## To Trapperkeeper Or Not To Trapperkeeper
Trapperkeeper gives us a lot of flexibility on how we decide to package and deploy applications and services. When should you use it? The easiest rule of thumb is: if it's possible to expose your code as a simple library with no dependencies on Trapperkeeper, it's highly preferable to go that route. Here are some things that might be reasonable indicators that you should consider exposing your code via a Trapperkeeper service:
* You're writing a clojure web service and there is a greater-than-zero percent chance that you will eventually want to be able to run it inside of the same embedded web server instance as another web service.
* Your code initializes some long-lived, stateful resource that needs to be used by other code, and that other code might not want/need to be responsible for explicitly managing the lifecycle of your resource
* Your code has a need for a managed lifecycle; initialization / startup, shutdown / cleanup
* Your code has a dependency on some other code that has a managed lifecycle
* Your code requires external configuration that you would like to make consistent with other puppetlabs / Trapperkeeper applications
## Separating Logic From Service Definitions
In general, it's a good idea to keep the code that implements your business logic completely separated from the Trapperkeeper service binding. This makes it much easier to test your functions as functions, without the need to boot up the whole framework. It also makes your code more re-usable and portable. Here's a more concrete example:
*DON'T DO THIS:*
```clj
(defprotocol CalculatorService
(add [this x y]))
(defservice calculator-service
CalculatorService
[]
(add [this x y] (+ x y)))
```
This is better:
```clj
(ns calculator.core)
(defn add [x y] (+ x y))
```
```clj
(ns calculator.service
(:require calculator.core :as core))
(defprotocol CalculatorService
(add [this x y]))
(defservice calculator-service
CalculatorService
[]
(add [this x y] (core/add x y)))
```
This way, you can test `calculator.core` directly, and re-use the functions it provides in other places without having to worry about Trapperkeeper.
## On Lifecycles
Trapperkeeper provides three lifecycle functions: init, start, and stop. Hopefully "stop" is pretty obvious. We've had some questions, though, about what the difference is between "init" and "start". Trapperkeeper doesn't impose a hard-and-fast rule that you must follow for how you use these, but here are some data points:
* The 'init' function of any service that you depend on will always be called before your 'init', and before any 'start'. The 'start' function of any service that you depend on will always be called before your 'start'.
* Trapperkeeper itself doesn't impose any semantics about what kinds of things you should do in each of those lifecycle phases. It's more about giving services the flexibility to establish a contract with other services. For example, a webserver service may specify that it only accepts the registration of web handlers during the 'init' phase, and that no new handlers can be added after it has completed its 'start' phase. (This is just a theoretical example; this restriction isn't actually true for our current jetty implementations.)
* The lifecycles are relatively new; as people start to use these lifecycles a bit more, we may end up shaking out a more concrete best-practice pattern. It's also possible we might end up introducing another phase or two to give more granularity... for now, we wanted to try to keep it fairly simple and flexible, and get a handle on what kinds of use cases people end up having for it.
## Testing Services
As we mentioned before, it's better to separate your business logic from your service definitions as much as possible, so that you can test your business logic functions directly. Thus, the vast majority of your tests should not need to involve Trapperkeeper at all. However, you probably will want to have a small handful of tests that do boot up a full Trapperkeeper app, so that you can verify that your dependencies work as expected, etc.
When writing tests that boot a Trapperkeeper app, the best way to do it is to use the helper testutils macros that we describe in the [testutils documentation](Test-Utils.md). They will take care of things like making sure the application is shut down cleanly after the test, and will generally just make your life easier.
OpenVoxProject-trapperkeeper-49527b2/documentation/Trapperkeeper-Quick-Start.md 0000664 0000000 0000000 00000004652 15224541352 0027751 0 ustar 00root root 0000000 0000000 # Trapperkeeper Quick Start
## Lein Template
A Leiningen template is available that shows a suggested project structure:
lein new trapperkeeper my.namespace/myproject
Once you've created a project from the template, you can run it via the lein alias:
lein tk
Note that the template is not intended to suggest a specific namespace organization; it's just intended to show you how to write a service, a web service, and tests for each.
## Hello World
Here's a "hello world" example for getting started with Trapperkeeper.
First, you need to define one or more services:
```clj
(ns hello
(:require [puppetlabs.trapperkeeper.core :refer [defservice]]))
;; A protocol that defines what functions our service will provide
(defprotocol HelloService
(hello [this])
(defservice hello-service
HelloService
;; dependencies: none for this service
[]
;; optional lifecycle functions that we can implement if we choose
(init [this context]
(println "Hello service initializing!")
context)
;; implement our protocol functions
(hello [this] (println "Hello there!")))
(defservice hello-consumer-service
;; no protocol required since this service doesn't export any functions.
;; express a dependency on the `hello` function from the `HelloService`.
[[:HelloService hello]]
(init [this context]
(println "Hello consumer initializing; hello service says:")
;; call the function from the `hello-service`!
(hello)
context))
```
Then, you need to define a Trapperkeeper bootstrap configuration file, which simply lists the services that you want to load at startup. This file should be named `bootstrap.cfg` and should be located at the root of your classpath (a good spot for it would be in your `resources` directory).
```clj
hello/hello-consumer-service
hello/hello-service
```
Lastly, set Trapperkeeper to be your `:main` in your Leiningen project file:
```clj
:main puppetlabs.trapperkeeper.main
```
And now you should be able to run the app via `lein run --config ...`. This example doesn't do much; for a more interesting example that shows how you can use Trapperkeeper to create a web application, check out the [Example Web Service](https://github.com/puppetlabs/trapperkeeper-webserver-jetty9/tree/master/examples/ring_app) included in the Trapperkeeper webserver service project. To get started defining your own services in Trapperkeeper, head to the [Defining Services](Defining-Services.md) page.

;;;; Application Shutdown Support
;;;;
;;;; The next section of this namespace
;;;; provides top-level functions to be called by TrapperKeeper internally
;;;; and a shutdown service for application services to utilize.
;;;;
;;;; Performing the actual shutdown is relatively easy, but dealing with
;;;; exceptions during shutdown and providing various ways for services
;;;; to trigger shutdown make up most of the code in this namespace.
;;;;
;;;; During development of this namespace we wanted to ensure that the
;;;; shutdown sequence occurred on the main thread and not on some
;;;; service's worker thread. Because of this, a Clojure `promise` is
;;;; used to pass contextual shutdown information back to the main thread,
;;;; at which point it is responsible for calling back into this namespace
;;;; to perform the appropriate shutdown steps.
;;;;
;;;; As a consequence of the implementation, the main blocking behavior of
;;;; TrapperKeeper is defined here by `wait-for-app-shutdown`. This function
;;;; simply attempts to dereference the above mentioned promise, which
;;;; until it is realized (e.g. by a call to `deliver`) will block, and the
;;;; delivered value returned. This value will contain contextual information
;;;; regarding the cause of the shutdown, and is intended to be passed back
;;;; in to the top-level functions that perform various shutdown steps.

# Trapperkeeper
Trapperkeeper is a Clojure framework for hosting long-running applications and services.
You can think of it as a sort of "binder" for Ring applications and other modular bits of Clojure code.
## Installation
Add the following dependency to your `project.clj` file:
[](http://clojars.org/org.openvoxproject/trapperkeeper)
## Documentation
You can find a quick-start, example code, and lots and lots of documentation in our:
* [Documentation](documentation/Index.md)
## Lein Template
A Leiningen template is available that shows a suggested project structure:
lein new trapperkeeper my.namespace/myproject
Once you've created a project from the template, you can run it via the lein alias:
lein tk
Note that the template is not intended to suggest a specific namespace organization;
it's just intended to show you how to write a service, a web service, and tests
for each.
## Related Projects
Here are some additional projects that provide Trapperkeeper services, and
other related functionality:
* [trapperkeeper-webserver-jetty9](https://github.com/openvoxproject/trapperkeeper-webserver-jetty9): a Jetty9-based webserver for use with TK applications
* [trapperkeeper-rpc](https://github.com/puppetlabs/trapperkeeper-rpc): a TK service that allows you to easily build a way to call remote TK services over RPC
* [trapperkeeper-metrics](https://github.com/openvoxproject/trapperkeeper-metrics): a TK service that manages the life cycle of a [MetricRegistry](https://github.com/dropwizard/metrics), so that all of your TK services can register metrics with a common configuration syntax.
* [trapperkeeper-comidi-metrics](https://github.com/openvoxproject/trapperkeeper-comidi-metrics): a TK utility library that provides middleware to automatically generate metrics for all requests to each of your bidi/comidi HTTP routes.
* [trapperkeeper-status](https://github.com/openvoxproject/trapperkeeper-status): a TK service that provides a mechanism for registering status callbacks for all of your other TK services, and web API for requesting status information about the entire TK system.
* [trapperkeeper-scheduler](https://github.com/openvoxproject/trapperkeeper-scheduler): a TK service that provides an API for scheduling periodic background tasks
