- re-label Client/Server to Inbound/Outbound for netty settings
description
- move to just using exactly one class loader for all reflective
activities of the ActorSystem, which is either the context class
loader or the one which loaded the ActorSystem’s class; document that
putting Akka on boot class path will not work
- be more careful with initializing the Client- and ServerBootstrap
- rename Port to DesiredPortFromConfig to discourage misuse
- write test for NettySettings
- various small fixes
- it is customary to use class name for categorizing logs, hence we
should support it; class is taken from logSource.getClass
- update SLF4J module to use logClass as category and set logSource in
MDC "akkaSource"
- add docs
* Changed signatures and constructor of MessageDispatcherConfigurator
* Changed Dispatchers.lookup, keep configurators instead of dispatchers
* Removed most of the Dispatchers.newX methods, newDispatcher is still there because of priority mailbox
* How should we make it easy to configure priority mailbox?
* Changed tons tests
* Documentation and ScalaDoc is not updated yet
* Some tests in ActorModelSpec are temporary ignored due to failure
* Aligned the Java and Scala documentation for Actors
* Implemented hotswap samples in Java, and documented in same way as Scala docs
* Improved Actors (Scala) docs
* Fixed wrong preRestart and postRestart in UntypedActor
* Changed name of Dispatchers.fromConfig to newFromConfig and made it Java friendly
* Added ActorRef.ask with Timeout parameter in addition to the timeoutMillis
- create RemoteActorRef in actorFor
- simplify send/receive because Futures/Exceptions do not go over the
wire anymore
- add RemoteCommunicationSpec which uses two ActorSystems communicating
in the same JVM via TCP socket
The reason for the previously failing test case was that Jenkins has
only two (logical) cores and the test config sets the
core-pool-size-factor to 2, meaning four threads. This is not enough to
have four Futures waiting (as per the test) and one actor which actually
does the work (the guardian in this case). Hence, make it so that
core-pool-size-min gives the absolute minimum and set the default of
that to eight.
While doing so I cleaned up the MessageDispatcherConfigurator to not use
HOF since now configuration items are not optional anymore, yielding a
flow which is much more readily understandable.
- run closeScheduler upon ActorSystem termination (directly)
- this will execute all outstanding tasks (dispatcher shutdowns have
been queued already, because the last actor has already exited)
- further use of the scheduler (e.g. from tasks just being run) results
in IllegalStateException
- catch such exceptions in DefaultPromise&MessageDispatcher in case of
self-rescheduling tasks and execute final action immediately
- also silently stop recurring tasks
- it was telling all children to stop(), then waited for the
ChildTerminated messages and finally terminated itself
- this worked fine, except when the stop came from the supervisor, i.e.
the recipient was suspended and did not process the ChildTerminated
- so, as the mirror of Supervise() that it is, I changed
ChildTerminated() to be a system message and instead of stopping
processing normal messages by checking the stopping flag, just suspend
the actor while awaiting the ChildTerminated's to flow in.
* Dispatchers need Scheduler to be able to shutdown themselves. Stop Scheduler after dispatchers.
* Changed CallingThreadDispatcher global object to Extension, since it holds map of references to mailboxes. Will be GC:ed when system is GC:ed.
* Made testActor lazy, since it is not used in all tests, and it creates CallingThreadDispatcher.
* Activated some java tests that were not running
* Many tests were not stopping created ActorSystems. VERY IMPORTANT TO STOP ActorSystem in tests. Use AkkaSpec as much as possible.
* Used profiler to verify (and find) dangling ActorSystemImpl and threads from dispatchers.
* FutureSpec creates ForkJoinPool threads that are not cleared, but number of threads don't grow so it's not a problem.
* Fixed obvious
* Created tickets for several, #1408, #1409, #1410, #1412, #1415, 1416, #1418
* Moved LoggingReceive from akka.actor to akka.event
* Touched several of the FIXME to make them visible in code review
