- add “mailbox-requirement” key to dispatcher section
- split out mailbox section, add akka.actor.default-mailbox
- rewrite findMarker method and use it for Props.create() and getting
the required mailbox of an actor
- add ProducesMessageQueue trait for MailboxType so that requirements
can be checked before trying to create the actor for real
- verify actor as well as dispatcher requirements for message queue
before creation, even in remote-deployed case
- change MessageDispatcher constructor to take a Configurator, add that
to migration guide
- IAR is subclass of AR and SAR
- all concrete ARs implement IAR
- move sendSystemMessage to IAR
all in preparation for unifying the ActorPath look-up for local&remote
actor refs
- 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
(cascading into all dispatchers, mailboxes, other stuff; had to move
deadLetter stuff to ActorSystem again and split its initialization due
to cyclic dependency)
- 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
- every actor is now supervised, where the root of the tree is
app.guardian, which has its supervisor field set to a special ActorRef
obtained from provider.theOneWhoWalksTheBubblesOfSpaceTime (this name
is meant to indicate that this ref is outside of the universe, cf.
Michio Kaku)
- changed all tests to obtain specially supervised children (i.e. not
top-level) via (supervisor ? Props).as[ActorRef].get
- add private[akka] ScalaActorRef.sendSystemMessage for sending
Supervise()
- everything routing or remote is broken wrt. supervision, as that was
not “properly” implemented to begin with, will be tackled after
app/supervision/eventbus/AkkaSpec are stabilized enough
- 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
