* mapAsync + ask should be the first choice
* add missing Source.queue
* prefer actorRefWithAck
* move ActorPublisher and ActorSubscriber to the end
with additional warning
* fix wrong doc of SourceQueue offer
* and add missing java api
* Add comprehensive tests
* Add documentation
* Damn comma after rebase
* Add documentation for foldAsync and scanAsync
* Rename aggreator and aggreating to current
* Remove out availability check
* Revert removing out and some refactors
* Formatting documentation
* Use after instead of Promise in test
* Use package reference to after and some refactoring
The deployment configuration is realized as an internally linked list,
which makes it allocation-free in the common case but retains full
extensibility.
This is the first step towards a completely new and optimized actor
implementation for Akka Typed. The full previously existing test suite
passes for both implementations. The following is an incomplete list of
things that remain to be done:
* document the semantic differences between untyped and typed, in
particular around actor restarts and the delivery ordering guarantees
for Terminated messages (also document the difference between
ActorSystemImpl and ActorSystemAdapter)
* implement EventStream and logging—this currently just delegates to an
extra untyped ActorSystem (of course To Be Fixed)
* implement dispatcher selection
* implement and test queue size limitation
* implement optimized message queue instead of CLQ (for zero-allocation
messaging)
* clean up test log output (something does not work with TestEventListener
and EventFilter for ActorSystemImpl tests)
* document the capabilities (or more appropriately: the limitations) of
interoperability between ActorSystemImpl and ActorSystemAdapter
* fix ActorPath UID generation (i.e. make sure that everything gets a
meaningful value instead of zero)
* re-evaluate throughput/rescheduling logic in ActorCell
Oh, and by the way: as per PerformanceSpec (doing simple ping-pong) the
new implementation is ca. 30% faster than the adapter over akka-actor
:-)
This is useful in at least two scenarios:
- Unit testing actors that communicate to their parent directly
- Testing re-creating (typically persistent) actors with the same name
* fix for infinite timeout disabling timeout infrastructure (#20817)
* filtering out timeout-access header in tests where necessary (#20817)
* filtering out timeout-access header in additional tests (#20817)
* added DummyCancellable object to avoid allocation (#20817)
* added test showing that timeout is correctly reset for both infinite as well as finite initial request-timeout (#20817)
