- 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
- gets rid of one field plus object plus allocation per mailbox
- retained same semantics for both roles for now (someone may try to
take atomic advantage of this unification later)
- rename MessageInvocation to Envelope (same for System...)
- rename MessageQueue to Mailbox and include ExecutableMailbox code
- make MailboxType act as factory, so users can provide their own
- properly type mailbox field as Mailbox everywhere
- adapt CallingThreadDispatcher and some tests
- create DeadletterMailbox and use it to replace actor’s mailbox on
terminate()
