Subject: [PATCH 41/79] Set worker as target in the WorkerEvent object

The listeners might want to have access to the worker as its target,
so make sure the target is set into the WorkerEvent class. Update
all tests to inject a worker interface mock for this to pass all tests
again.

Subject: [PATCH 43/79] Remove ListenerEvents calls

The detachment of listeners is not required, so can be left out.
The attachment of default listeners is now done in the factory,
the only feature removed is the attachment of queue-specific
listeners. This will be added back later.

 Worker stop conditions
 ----------------------
 
-The worker will be a long running call, due to the `while(true){ /*...*/ }` loop it contains inside the `processQueue()`
-method. However, there are reasons to cancel the loop and stop the worker to continue. PHP is not the best language for

+The worker will be a long running call, due to the `while(...){ /*...*/ }` loop it
+contains inside the `processQueue()` method. However, there are reasons to cancel the loop and stop the worker to
+continue. PHP is not the best language for creating infinite running scripts.
 
-It is wise to abort the script frequently, for example after x number of cycles in the `while` loop. A worker is
-initiated with a `WorkerOptions` class, where it is possible to set a maximum number of runs. In this same options class,
-a maximum memory level can be set. If you have accidentally a memory leak, this option can make sure the script aborts
-eventually after reaching this level.
+It is wise to abort the script frequently, for example after x number of cycles in the `while` loop. 
 
-Both options can be set at the `worker` key in the SlmQueue configuration:
-
-```php
-'slm_queue' => array(
-    'worker' => array(
-        'max_runs'   => 100000,           // 10,000 runs
-        'max_memory' => 20 * 1024 * 1024, // 20 MB
-    )
-),
-```
-
-Secondly, it is possible to catch a stop condition under Linux-like systems (as well as OS X). If a worker is started
-from the command line interface (CLI), it is possible to send a SIGTERM or SiGINT call to the worker. SlmQueue is smart 
-enough not to quit the script diretly, but let the job finish its work first and then break out of the loop. For Windows
-users this option is not available.
+Various build-in strategies (['see 6.Events'](6.Events.md)) are used to decide if the worker should exit. These
+strategies are aggregate listeners that hook into events the worker dispatches. Any listener may call a method
+on the passed event `WorkerEvent::exitWorkerLoop()`. Which the worker will check the event the next iteration of the loop.

-SlmQueue triggers events at selected moments in the worker code flow. This enables users of SlmQueue to create hooks at
-several points:

- * `WorkerEvent::EVENT_PROCESS_QUEUE_POST`: just after processing ends
- * `WorkerEvent::EVENT_PROCESS_JOB_PRE`: just before a job will be processed
- * `WorkerEvent::EVENT_PROCESS_JOB_POST`: just after a job has been processed
+```
+processQueue
+    trigger event 'bootstrap'
+
+    while event says continue processing
+       trigger event 'process'
+
+    trigger event 'finish'
+
+    trigger event 'state'
+
+```
+
+Worker Strategies
+-----------------
+
+To get some useful results it is required to register so called 'worker strategies' to the worker. SlmQueue makes this trivial via configuration.
+
+Worker strategies are aggregate listeners which are created via a plugin manager.
+
+At least one worker strategy listening to the bootstrap event must be registered to the worker. The Worker Factory will throw an exception if its not. SlmQueue attaches the provided `AttachQueueListenersStrategy` to do just that.
+
+It is worth noting that events will be dispatched from the worker (obviously) but can also be dispatch from within worker strategies.
+
+The plugin manager ensures they extend `SlmQueue\Listener\Strategy\AbstractStrategy` and each worker strategy therefore gains the following capabilities;
+
+### Accept options 
+
+Configuration options are passed by the plugin manager to the constructor of an worker strategy. Setter methods will be called for each option. If a setter does not exist an exception will be thrown.
+
+```
+'SlmQueue\Strategy\MaxRunStrategy' => array('max_runs' => 10);
+
+```
+Such a config will result in an MaxRunStrategy instance of which the setMaxRuns method is called with '10'.
+
+*The optional 'priority' option is used when the aggregates listeners are are registered with event manager and is thereafter removed from the passed options. This means a Worker Strategy cannot have this option.*
+
+### Request to stop processing the queue
+
+Worker strategies may inform the worker to stop processing the queue. Or more concrete; invalidate the condition of the while loop.
+
+```
+public function onSomeListener(WorkerEvent $event)
+{
+    $event->exitWorkerLoop();
+    ...
+}
+```
+
+### Do something before or after the processing of a queue
+
+While processing a queue it might be required to execute some setup- or teardown logic. A worker strategy may listen to the `bootstrap` and/or `finish` event to do just this.
+
+```
+/**
+ * @param EventManagerInterface $events
+ */
+public function attach(EventManagerInterface $events)
+{
+    $this->listeners[] = $events->attach(
+        WorkerEvent::EVENT_BOOTSTRAP,
+        array($this, 'onBootstrap')
+    );
+    $this->listeners[] = $events->attach(
+        WorkerEvent::EVENT_FINISH,
+        array($this, 'onFinish')
+    );
+}
+
+/**
+ * @param WorkerEvent $e
+ */
+public function onBootstrap(WorkerEvent $e)
+{
+   // setup code
+}
+
+/**
+ * @param WorkerEvent $e
+ */
+public function onFinish(WorkerEvent $e)
+{
+   // teardown code
+}
+```
+
+### Do something before or after the processing of a job
+
+For some types of jobs it might be required to do something before or after the execution of an individual job. 
+
+tbd (events vs priority)
+
+### Report on 'the thing' a strategy is tasked with.
+
+A worker strategy may report a state. A state is simply a string which will be returned when the `WorkerEvent::EVENT_PROCESS_STATE` is received.
+
+From the MaxRunStrategy;
+
+```
+public function onSomeListener(WorkerEvent $event)
+{
+    $this->runCount++;
+
+    if ($this->maxRuns && $this->runCount >= $this->maxRuns) {
+        $event->exitWorkerLoop();
+
+        $this->state = sprintf('maximum of %s jobs processed', $this->runCount);
+    } else {
+        $this->state = sprintf('%s jobs processed', $this->runCount);
+    }
+}
+```
+
+### Dispatch WorkerEvents
+
+A worker strategy may ask the worker to dispatch events.
+
+From the ProcessQueueStrategy
+
+```
+public function onJobPop(WorkerEvent $e)
+{
+    $queue   = $e->getQueue();
+    $options = $e->getOptions();
+    $job     = $queue->pop($options);
+
+    // The queue may return null, for instance if a timeout was set
+    if (!$job instanceof JobInterface) {
+        /** @var AbstractWorker $worker */
+        $worker = $e->getTarget();
+
+        $worker->getEventManager()->trigger(WorkerEvent::EVENT_PROCESS_IDLE, $e);
+
+        // make sure the event doesn't propagate
+        $e->stopPropagation();
+
+        return;
+    }
+
+    $e->setJob($job);
+}
+```
+
+Configuration
+-------------
+
+
+Services
+--------
+
+Worker strategies are regular ZF2 services that are instanciated via a plugin manager. If a worker strategy has dependancies on other services it should be created it via service factory.
 
-Any listener waiting for above events will be passed a `WorkerEvent` class which contains a reference to the queue. The
-`EVENT_PROCESS_JOB_PRE` and `EVENT_PROCESS_JOB_POST` events also have a reference to the job class.
+**The plugin manager is configured to *not* share services.**
+
+WorkerEvent
+-----------
+
+Events the worker *and* worker strategies may dispatch;
+
+ * `WorkerEvent::EVENT_BOOTSTRAP` just before loop is entered
+ * `WorkerEvent::EVENT_FINISH` just after the loop has exited
+ * `WorkerEvent::EVENT_PROCESS` fetch and process job(s)
+ * `WorkerEvent::EVENT_PROCESS_IDLE` when the queue is empty
+ * `WorkerEvent::EVENT_PROCESS_STATE` collects 'states' from strategies.
+ 
+
+
+Any listener waiting for above events will be passed a `WorkerEvent` class which contains a reference to the queue. The `EVENT_PROCESS` event also has a reference to the job instance.

+Provided Worker Strategies
+--------------------------
+
+#### AttachQueueListenersStrategy
+
+The purpose of this strategy is to register additional strategies that are specific to the queue that is being processed.
+
+After registering any additional worker strategies it will unregister itself as a listener. Finally it halts the event propagation and re-triggers the `bootstrap` event.
+
+A new cycle of bootstraping will occure but now with additional queue specific strategies.
+
+listens to:
+
+- `bootstrap` event at priority PHP_MAX_INT
+
+triggers:
+
+- `bootstrap`
+
+throws: 
+
+- RunTimeException if the `process` event isn't listened to by any registered strategy.
+  
+This strategy is enabled by default for all queue's.
+
+#### FileWatchStrategy
+
+This strategy is able to 'watch' files by creating a hash of their contents. If it detects a change it will request to stop processing the queue. This is useful if you have something like [supervisor](7.WorkerManagement.md) automaticly restarting the worker process.
+
+The strategy builds a list of files it needs to watch via a preg_match on the filenames within the application.
+
+listens to:
+
+- `idle` event at priority 1
+- `process` event at priority -1000
+- `state` event at priority 1
+
+options:
+
+- pattern defaults to '/^\.\/(config|module).*\.(php|phtml)$/'
+
+This strategy is not enabled by default. It can be slow and is recommended for development only. In production you may watch a single file.
+
+#### InterruptStrategy
+
+The InterruptStrategy is able to catch a stop condition under Linux-like systems (as well as OS X). If a worker is started from the command line interface (CLI), it is possible to send a SIGTERM or SiGINT call to the worker. SlmQueue is smart enough not to quit the script directly, but let the job finish its work first and then break out of the loop. On Windows systems this strategy does nothing.
+
+listens to:
+
+- `idle` event at priority 1
+- `process` event at priority -1000
+- `state` event at priority 1
+
+This strategy is enabled by default for all queue's.
+
+#### LogJobStrategy
+
+Simple outputs to the console a when it begin executing a job and when it is done.
+
+listens to:
+
+ - `process` event at priority 1000
+ - `process` event at priority -1000
+
+#### MaxMemoryStrategy
+
+The MaxMemoryStrategy will measure the amount of memory allocated to PHP after each processed job. It will request to exit when a threshold is exceeded.
+
+Note that an individual job may exceed this threshold during it's live time. But if you have a memory leak this strategy can make sure the script aborts eventually.
+
+listens to:
+
+- `idle` event at priority 1
+- `process` event at priority -1000
+- `state` event at priority 1 
+
+options:
+
+- max_memory defaults to 100\*1024\*1024
+
+This strategy is enabled by default for all queue's.
+
+#### MaxRunsStrategy
+
+The MaxRunStrategy will request to exit after a set number of jobs have been processed.
+
+listens to:
+
+- `idle` event at priority 1
+- `process` event at priority -1000 
+- `state` event at priority 1 
+
+options:
+
+- max_runs defaults to 100000
+
+This strategy is enabled by default for all queue's.
+
+#### ProcessQueueStrategy
+
+Responsible for quering the queue for jobs and executing them.
+
+listens to:
+
+- `process` event at priority 2
+- `process` event at priority 1
+
+triggers:
+
+- `idle` if the queue returns null (it might be empty or timed out)
+
+
 Using the shared event manager
 ------------------------------
 
 Instead of direct access to the worker's event manager, the shared manager is available to register events too:

 namespace MyModule;
 
 use SlmQueue\Worker\WorkerEvent;

-Using an aggregate listener
----------------------------
+An example
+----------
 
-If it is required to listen at multiple events, an aggregate listener is a powerful tool to hook into multiple events of
-the same event manager. A good example is i18n: a job is given a locale if the job performs localized actions. This
-locale is set to the translator just before processing starts. The original locale is reverted when the job has finished

-The last step is to register the aggregate listener to the event manager of the worker object:
+Since this worker strategy has a dependancy that needs to be injected we should create a factory for it.
 
 ```php
-public function onBootstrap(MvcEvent $e)
-{
-    $sm = $e->getApplication()->getServiceManager();
+<?php
+namespace MyModule\Strategy\Factory;

-    $translator = $sm->get('MvcTranslator');
+use MyModule\Strategy\JobTranslatorStrategy;
+use Zend\ServiceManager\FactoryInterface;
+use Zend\ServiceManager\ServiceLocatorInterface;
 
-    /** @var $worker \SlmQueueDoctrine\Worker\DoctrineWorker */
-    $worker = $sm->get('SlmQueueDoctrine\Worker\DoctrineWorker');
+class JobTranslatorStrategyFactory implements FactoryInterface
+{
+    /**
+     * Create service
+     *

+    	$sm         = $serviceLocator->getServiceLocator();
+        
+    	/** @var $sm \Zend\Mvc\I18n\Translator */
+    	$translator = $sm->get('MvcTranslator');

-    $worker->getEventManager()->attachAggregate($listener);
+    	$strategy   = new JobTranslatorStrategy($translator);
+
+        return $strategy;
+    }
 }
 ```
 
+Finally add two configuration settings;
+
+ 1. Register the factory to the plugin manager to the Strategy Manager.
+ 2. Add the strategy by name to the worker strategies. Note we can do this for all queue's or for specific ones.
+
