If automatically generated names contains * and ?, they might do
something strange when being looked up. There was no real issue with our
current tests, but I just want to avoid the issue.
- implementation of this cool feature is now astonishingly simple:
context.actorSelection("child/*") ! msg
- docs propagate to ActorSystem/ActorContext
- remove Props.randomName and associated logic
- ActorRefFactory contains AtomicLong which is used to generate unique
children names
- base64-like encoding is used with reverse “digit” order
- disallow given names which are null, empty or start with ‘$’
- random names start have ‘$’ prepended (‘$’ not being one of the 64
characters)
- special marker “$_” for tempPath until “/tmp” supervisor is introduced
- TestActorRef uses globally unique “$$” prefix, as it creates actors
beneath any supervisor as instructed by the user
- 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
- 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)
