- 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)
* 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.
* 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
