- add new config item "buddy-wakeup-threshold" which defaults to 5
- if BWT>=0, then check mailbox.numberOfMessages in case the target
actor was not scheduled during dispatch and schedule a buddie if that
is found >=BWT (BWT is a getfield)
- if during unregister() there are messages in the queue, schedule a
buddie
This way people can tune which behavior they want, knowing full well
that numberOfMessages is O(n).
* Config property jvmExitOnFatalError
* System.exit in case of fatal error, such as OutOfMemoryError
* Adjusted NonFatal extractor, ok with StackOverflowError, not ok with LinkageError
* Removed the actor null check in ActorCell
* 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
* Config lib 4f3a91f
* All reference files named reference.conf, all will be loaded
* Usage of ConfigFactor.load as default way
* Extensions use same config as ActorSystem.settings.config
* Split config reference to one for each module/extension.
* Adjusted signature of registerExtension to avoid race of extension init
* Moved Duration.dilated to testkit
* TestKitExtension
* RemoteExtension
* SerializationExtension
* Durable mailboxes extensions
* Fixed broken serialization bindings and added test
* Updated configuration documentation
* System properties akka.remote.hostname akka.remote.port replaced with akka.remote.server.hostname and akka.remote.server.port
* Adjustments of ActorSystem initialization. Still don't like the two-phase constructor/init flow. Very fragile for changes.
Review fixes. SerializationExtension
* All default values removed from code and loaded from akka-actor-reference.conf, located in src/main/resources (included in jar)
* Default test configuration included in AkkaSpec instead of using akka.test.conf, avoids problems when running test (in IDE) and forgetting to use -Dakka.mode=test.
* System.properties used first, if availble
* Next step will be to split akka-actor-reference.conf in separate -reference for each module
- create ActorSystemImpl trait to make ActorSystem fully abstract
- add Java API for constructing (ActorSystem.create(...))
- only go through factory methods because .start() has become necessary
- rename all user-facing occurrences of “app” to “system” (Actor trait
and TestKit/AkkaSpec)
- pass ActorSystemImpl to ActorRefs upon creation, which means that
actorOf() and friends need such an argument, which must be provided to
the ActorRefProvider by the ActorRefFactory implementation
- moved typed actor factories to app/context (like actor factories)
- fixed a few misplaced supervision changes, all such tests green now
- actually test akka-reference.conf in ConfigSpec
- made DispatcherActorSpec more deterministic (failed intermittently
here, was due to race towards thread pool)
- wrapped all actor initialization failures into
ActorInitializationException and made sure that this leads to Stop
- default to Stop on ActorKilledException
- fixed ActorModelSpec to separately supervise the “waves of actors”
because otherwise the app.guardian is way too busy processing all
those ChildTerminated messages
- change ActorCell._children from Vector[Stats] to TreeMap[ActorRef,
Stats] for performance reasons, have not measured memory impact, yet
- ensured that InterrupedException does not leave current thread via
Failed message to supervisor (wrapped in ActorInterruptedException)
- set core-size=1 and max-size=4 for default dispatcher during test
