- PropertyMaster is the only place in Akka which calls
ClassLoader.getClass (apart from kernel, which might be special)
- all PropertyMaster methods (there are only three) take a ClassManifest
of what is to be constructed, and they verify that the obtained object
is actually compatible with the required type
Other stuff:
- noticed that I had forgotten to change to ExtendedActorSystem when
constructing Extensions by ExtensionKey (damn you, reflection!)
- moved Serializer.currentSystem into JavaSerializer, because that’s the
only one needing it (it’s only used in readResolve() methods)
- Serializers are constructed now with one-arg constructor taking
ExtendedActorSystem (if that exists, otherwise no-arg as before), to
allow JavaSerializer to do its magic; possibly necessary for others as
well
- Removed all Option[ClassLoader] signatures
- made it so that the ActorSystem will try context class loader, then
the class loader which loaded the class actually calling into
ActorSystem.apply, then the loader which loaded ActorSystemImpl
- for the second of the above I added a (reflectively accessed hopefully
safe) facility for getting caller Class[_] objects by using
sun.reflect.Reflection; this is optional an defaults to None, e.g. on
Android, which means that getting the caller’s classloader is done on
a best effort basis (there’s nothing we can do because a StackTrace
does not contain actual Class[_] objects).
- refactored DurableMailbox to contain the owner val and use that
instead of declaring that in all subclasses
- add provider, guardian, systemGuardian and deathWatch to it
- make ActorSystemImpl extend ExtendedActorSystem
- use ExtendedActorSystem for creating extensions, thereby limiting the
access extensions get to just those four published methods.
* Added sample and documentation for how to create extension for application specific config
* Simplified java usage of ExtensionIdProvider, more aligned with how it is done in scala
* 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.
- used only to keep the uniquifying logger counter per-ActorSystem
- add convenience-class for writing an extension with only two lines
overhead (Java: three)!
* 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
- type is encoded in key, allowing proper typing in Scala & Java
- test cases for Scala & Java are included to ensure that the API makes
sense and does not break
