Subject: [PATCH 21/35] remove ActorRef.stop()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- replace ActorRef.stop() by ActorRefFactory.stop(child) everywhere
- ActorCell “optimizes” this to remove the child from its childrenRefs
  in order to allow immediate recycling of the name
- the lost soul must have a place, for which the Locker has been
  created, where Davy Jones will happily rebind the soul to his ship
  (i.e. set “parent” to the locker to avoid mem leak) and periodically
  revisit it (.stop(), in case of that being lost in comm failure,
  similar .watch() to re-check liveness)

 The Dispatcher is an important piece that allows you to configure the right semantics and parameters for optimal performance, throughput and scalability. Different Actors have different needs.
 
-Akka supports dispatchers for both event-driven lightweight threads, allowing creation of millions threads on a single workstation, and thread-based Actors, where each dispatcher is bound to a dedicated OS thread.
+Akka supports dispatchers for both event-driven lightweight threads, allowing creation of millions of threads on a single workstation, and thread-based Actors, where each dispatcher is bound to a dedicated OS thread.
 
 The event-based Actors currently consume ~600 bytes per Actor which means that you can create more than 6.5 million Actors on 4 GB RAM.
 
 Default dispatcher
 ------------------
 
-For most scenarios the default settings are the best. Here we have one single event-based dispatcher for all Actors created. The default dispatcher used is "GlobalDispatcher" which also is retrievable in ``akka.dispatch.Dispatchers.globalDispatcher``.
-The Dispatcher specified in the :ref:`configuration` as "default-dispatcher" is  as ``Dispatchers.defaultGlobalDispatcher``.
+For most scenarios the default settings are the best. Here we have one single event-based dispatcher for all Actors created.
+The default dispatcher is available from the ``ActorSystem.dispatcher`` and can be configured in the ``akka.actor.default-dispatcher``
+section of the :ref:`configuration`.
 
-The "GlobalDispatcher" is not configurable but will use default parameters given by Akka itself.
-
-But if you feel that you are starting to contend on the single dispatcher (the 'Executor' and its queue) or want to group a specific set of Actors for a dedicated dispatcher for better flexibility and configurability then you can override the defaults and define your own dispatcher. See below for details on which ones are available and how they can be configured.
+If you are starting to get contention on the single dispatcher (the ``Executor`` and its queue) or want to group a specific set of Actors
+for a dedicated dispatcher for better flexibility and configurability then you can override the defaults and define your own dispatcher.
+See below for details on which ones are available and how they can be configured.
 
 Setting the dispatcher
 ----------------------
 
-Normally you set the dispatcher from within the Actor itself. The dispatcher is defined by the 'dispatcher: MessageDispatcher' member field in 'ActorRef'.
+You specify the dispatcher to use when creating an actor.
 
-.. code-block:: java
-
-  class MyActor extends UntypedActor {
-    public MyActor() {
-      getContext().setDispatcher(..); // set the dispatcher
-    }
-     ...
-  }
-
-You can also set the dispatcher for an Actor **before** it has been started:
-
-.. code-block:: java
-
-  actorRef.setDispatcher(dispatcher);
+.. includecode:: code/akka/docs/dispatcher/DispatcherDocTestBase.java
+   :include: imports,defining-dispatcher
 
 Types of dispatchers
 --------------------
 
-There are six different types of message dispatchers:
+There are 4 different types of message dispatchers:
 
-* Thread-based
+* Thread-based (Pinned)
 * Event-based
 * Priority event-based
-* Work-stealing event-based
+* Work-sharing (Balancing)
 
-Factory methods for all of these, including global versions of some of them, are in the 'akka.dispatch.Dispatchers' object.
+It is recommended to define the dispatcher in :ref:`configuration` to allow for tuning for different environments.
+
+Example of a custom event-based dispatcher, which can be fetched with ``system.dispatcherFactory().lookup("my-dispatcher")`` 
+as in the example above:
+
+.. includecode:: ../scala/code/akka/docs/dispatcher/DispatcherDocSpec.scala#my-dispatcher-config
+
+Default values are taken from ``default-dispatcher``, i.e. all options doesn't need to be defined.
+
+.. warning::
+
+  Factory methods for creating dispatchers programmatically are available in ``akka.dispatch.Dispatchers``, i.e.
+  ``dispatcherFactory`` of the ``ActorSystem``. These methods will probably be changed or removed before
+  2.0 final release, because dispatchers need to be defined by configuration to work in a clustered setup.
 
 Let's now walk through the different dispatchers in more detail.
 
 Thread-based
 ^^^^^^^^^^^^
 
-The 'PinnedDispatcher' binds a dedicated OS thread to each specific Actor. The messages are posted to a 'LinkedBlockingQueue' which feeds the messages to the dispatcher one by one. A 'PinnedDispatcher' cannot be shared between actors. This dispatcher has worse performance and scalability than the event-based dispatcher but works great for creating "daemon" Actors that consumes a low frequency of messages and are allowed to go off and do their own thing for a longer period of time. Another advantage with this dispatcher is that Actors do not block threads for each other.

-.. code-block:: java
+The ``PinnedDispatcher`` can't be configured, but is created and associated with an actor like this:
 
-  Dispatcher dispatcher = Dispatchers.newPinnedDispatcher(actorRef);
-
-It would normally by used from within the actor like this:
-
-.. code-block:: java
-
-  class MyActor extends UntypedActor {
-    public MyActor() {
-      getContext().setDispatcher(Dispatchers.newPinnedDispatcher(getContext()));
-    }
-    ...
-  }
+.. includecode:: code/akka/docs/dispatcher/DispatcherDocTestBase.java#defining-pinned-dispatcher
 
 Event-based
 ^^^^^^^^^^^
 
-The 'Dispatcher' binds a set of Actors to a thread pool backed up by a 'BlockingQueue'. This dispatcher is highly configurable and supports a fluent configuration API to configure the 'BlockingQueue' (type of queue, max items etc.) as well as the thread pool.

+and supports a fluent configuration API to configure the ``BlockingQueue`` (type of queue, max items etc.) as well as the thread pool.
 
-The event-driven dispatchers **must be shared** between multiple Typed Actors and/or Actors. One best practice is to let each top-level Actor, e.g. the Actors you define in the declarative supervisor config, to get their own dispatcher but reuse the dispatcher for each new Actor that the top-level Actor creates. But you can also share dispatcher between multiple top-level Actors. This is very use-case specific and needs to be tried out on a case by case basis. The important thing is that Akka tries to provide you with the freedom you need to design and implement your system in the most efficient way in regards to performance, throughput and latency.

 It comes with many different predefined BlockingQueue configurations:
 
-* Bounded LinkedBlockingQueue
-* Unbounded LinkedBlockingQueue
-* Bounded ArrayBlockingQueue
-* Unbounded ArrayBlockingQueue
-* SynchronousQueue
+* Bounded `LinkedBlockingQueue <http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/LinkedBlockingQueue.html>`_
+* Unbounded `LinkedBlockingQueue <http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/LinkedBlockingQueue.html>`_

+* `SynchronousQueue <http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/SynchronousQueue.html>`_
 
-You can also set the rejection policy that should be used, e.g. what should be done if the dispatcher (e.g. the Actor) can't keep up and the mailbox is growing up to the limit defined. You can choose between four different rejection policies:
+When using a bounded queue and it has grown up to limit defined the message processing will run in the caller's
+thread as a way to slow him down and balance producer/consumer.
 
-* java.util.concurrent.ThreadPoolExecutor.CallerRuns - will run the message processing in the caller's thread as a way to slow him down and balance producer/consumer
-* java.util.concurrent.ThreadPoolExecutor.AbortPolicy - rejected messages by throwing a 'RejectedExecutionException'
-* java.util.concurrent.ThreadPoolExecutor.DiscardPolicy - discards the message (throws it away)
-* java.util.concurrent.ThreadPoolExecutor.DiscardOldestPolicy - discards the oldest message in the mailbox (throws it away)
+Here is an example of a bounded mailbox:
 
-You cane read more about these policies `here <http://java.sun.com/javase/6/docs/api/index.html?java/util/concurrent/RejectedExecutionHandler.html>`_.

-        .build());
-    }
-     ...
-  }
+.. includecode:: ../scala/code/akka/docs/dispatcher/DispatcherDocSpec.scala#my-bounded-config
 
 The standard :class:`Dispatcher` allows you to define the ``throughput`` it
 should have, as shown above. This defines the number of messages for a specific
 Actor the dispatcher should process in one single sweep; in other words, the
-dispatcher will bunch up to ``throughput`` message invocations together when
+dispatcher will batch process up to ``throughput`` messages together when
 having elected an actor to run.  Setting this to a higher number will increase
 throughput but lower fairness, and vice versa. If you don't specify it explicitly
 then it uses the value (5) defined for ``default-dispatcher`` in the :ref:`configuration`.

+ * Actor base trait that should be extended by or mixed to create an Actor with the semantics of the 'Actor Model':
+ * <a href="http://en.wikipedia.org/wiki/Actor_model">http://en.wikipedia.org/wiki/Actor_model</a>
+ *
+ * This class is the Java cousin to the [[akka.actor.Actor]] Scala interface.
  * Subclass this abstract class to create a MDB-style untyped actor.
- * <p/>
- * This class is meant to be used from Java.
- * <p/>
+ *
+ * An actor has a well-defined (non-cyclic) life-cycle.
+ *  - ''RUNNING'' (created and started actor) - can receive messages
+ *  - ''SHUTDOWN'' (when 'stop' or 'exit' is invoked) - can't do anything
+ *
+ * The Actor's own [[akka.actor.ActorRef]] is available as `getSelf()`, the current
+ * message’s sender as `getSender()` and the [[akka.actor.UntypedActorContext]] as
+ * `getContext()`. The only abstract method is `onReceive()` which is invoked for
+ * each processed message unless dynamically overridden using `getContext().become()`.
+ *
  * Here is an example on how to create and use an UntypedActor:
