- based on a wheel (AtomicReferenceArray) from which atomic
single-linked lists dangle
- no locks
- deterministic tests due to overridable time source
- also bring docs up to date
This means tightening types from Duration to FiniteDuration in several
places; a good thing, since we replace runtime complaints by compile
time errors.
- it’s a completely new-written thing in pure Java, so that “protected”
modifiers actually work and no ghost errors appear wrt. inheriting
from PartialFunction or similar
- it also features integration with the EventFilter
- all closure-based constructs are modeled as inner classes of the
JavaTestKit, where the user needs to override a single method which
will then be executed
- introducing RepointableActorRef, which starts out with an
UnstartedActorCell which can cheaply be created; the Supervise()
message will trigger child.activate() in the supervisor, which means
that the actual creation (now with normal ActorCell) happens exactly
in the right place and with the right semantics. Messages which were
enqueued to the dummy cell are transferred atomically into the
ActorCell (using normal .tell()), so message sends keep working
exactly as they used to
- this enables getting rid of the brittle synchronization around
RoutedActorRef by replacing that one with a RepointableActorRef
subclass which creates RoutedActorCells upon activate(), with the nice
benefit that there is no hurry then to get it right because the new
cell is constructed “on the side”
misc fixes:
- InvalidMessageException is now actually enforced when trying to send
“null”
- Mailboxes may be created without having an ActorCell, which can come
in handy later, because the cell is only needed when this mailbox is
going to be scheduled on some executor
- remove occurrences of Props(), which is equivalent to Props[Nothing],
which is equivalent to «bug»
- add test case which verifies that context.actorOf is still synchronous
- plus all the stuff I have forgotten.
- do not use futures, do not use different executors
- only use Poll token; schedule OR poller.poll in case of no message
available, depending on the sign of the poll timeout
- restructure receive method to avoid PartialFunction.orElse overhead
* ActorTimeout (akka.actor.timeout) was used to all sorts of things.
* TestKit default-timeout
* TypedActor timeout for non void methods
* Transactor coordinated-timeout
* ZeroMQ new-socket-timeout
* And in various tests
* Changed signatures and constructor of MessageDispatcherConfigurator
* Changed Dispatchers.lookup, keep configurators instead of dispatchers
* Removed most of the Dispatchers.newX methods, newDispatcher is still there because of priority mailbox
* How should we make it easy to configure priority mailbox?
* Changed tons tests
* Documentation and ScalaDoc is not updated yet
* Some tests in ActorModelSpec are temporary ignored due to failure
