- the same information is transmitted as sender, hence enabling
ChildTerminated to become a singleton
- make lastSender accessible in TestKit (needed now for DeathWatchSpec)
- fix nasty infinite loop when logging at the wrong moment during
shutdown
(since I know now what’s causing these Jenkins failures ;-) )
- include recipient in DeadLetter
- include recipient in calls to enqueue/systemEnqueue
- move DeadLetterMailbox to ActorSystem (saves some space, too)
- hook up DeadLetterMailbox so it sends DeadLetters to app.deadLetters,
which publishes them on the eventStream
- subscribe TestEventListener to DeadLetter and turn it into Warning
The generated warnings about ChildTerminated are very much correct, they
remind us that we still need to fix supervisor.stop() to await all
children’s death before actually committing suicide.
- enqueuing system messages to DeadLetterMailbox was broken in
principle, but not in practice for the current default deadLetter
implementation
- add assert that system messages are not enqueued multiple times
- *BusSpec was using incorrect compareSubscribers based on
identityHashCode, so moved the proper solution out of
BalancingDispatcher and into akka.util.Helpers and reuse that in all
places
BalancingDispatcherModelSpec is currently broken, leaves count==1 in
wavesOfActors test, committed anyway in order to check out where it
broke before this merge
most tests passing, everything compiling, but docs not updated and nasty
thread-leak preventing me from running the whole test-suite (which is
the reason for this commit: I want to chase down that one first).
- the app.mainbus is classified by Class[_] (currently lookup, will
possibly change to sub-class-aware) and accepts AnyRef messages
- LoggingBus handles akka.event-handlers from config specially:
+ start them as system services, supervised by SystemGuardian
+ keep their subscriptions in sync when logLevel_= is called
+ send them InitializeLogger(bus) message before subscribing them (so
they can register for extras like Mute/UnMute)
- two-phased start-up: first phase with actor-less stdout logging, then
subscription of config loggers, then remove stdout logger (logLevels
configurable separately)
- MainBusReaper watches registered receivers and unsubscribes them upon
death (started in phase 2)
- logger factory on Logging object, needs app/bus and log source;
default instance in app.log
- every actor is now supervised, where the root of the tree is
app.guardian, which has its supervisor field set to a special ActorRef
obtained from provider.theOneWhoWalksTheBubblesOfSpaceTime (this name
is meant to indicate that this ref is outside of the universe, cf.
Michio Kaku)
- changed all tests to obtain specially supervised children (i.e. not
top-level) via (supervisor ? Props).as[ActorRef].get
- add private[akka] ScalaActorRef.sendSystemMessage for sending
Supervise()
- everything routing or remote is broken wrt. supervision, as that was
not “properly” implemented to begin with, will be tackled after
app/supervision/eventbus/AkkaSpec are stabilized enough
- channel field was always set to NullChannel and not used
- receiver field is better put into the Mailbox, because there it takes
space only once per actor
- leaves only the bare SystemMessage to be queued
- add Logging trait for nicer interface
- add EventHandlerLogging class for offering the nice interface from
app.log
- add eventHandler instance to app and use that for all internal logging
(this means that some places (dispatchers, remoting) were infiltrated
by app just to do logging, but I think we'll need app in there soon
enough for other reasons)
- remove global Config
- pull everything which depended on it into new AkkaApplication
- leave EventHandler alone for the moment: that evil sucker gets his
very own AkkaApplication("akka-reference.conf") until we have settled
on an acceptable logging API without globals
- make akka-actor and akka-testkit compile
- TestKit uses implicit AkkaApplication passing for maximum convenience
- Actor object nearly completely removed, actor creation possible via
ActorRefFactory interface which is implemented by AkkaApplication and
ActorContext
- serialization of ActorRef is probably broken, and so is the reflective
RemoteSupport (now needs AkkaApplication constructor arg)
- everything else is still broken, including akka-actor-tests, so this
is of course all not runtime-tested
- make Scheduled==4 to allow bitwise operations
- unfold become(status) into three methods for better inlining
- optimize patterns in setAsIdle away: table switch is probably slower
than a single conditional
- fix LoggingReceiveSpec glitch wrt. async stop()
