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
:-)
* handle ConductorServiceTimeoutException and
DriverTimeoutException
* shutdown things properly, in the right order, and
without overwhelming the logs with exceptions
* otherwise AeronSink will continue sending outstanding messages
before completing
* this was noticed by RemoteDeathWatchSpec couldn't shutdown,
since it was trying to send to unknown
* for parallel serialziation/deserialization
* MergeHub for the outbound lanes
* BroadcastHub + filter for the inbound lanes, until we
have a PartitionHub
* simplify materialization of test stage
* add RemoteSendConsistencyWithThreeLanesSpec
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
* Move artery settings from remoting settings to dedicated class.
* #20587 Move hardcoded settings to configuration file.
* Copy reused settings from remote to the artery
Changes are https://github.com/real-logic/Aeron/releases/tag/1.0.1 :
> * Adjust incremental cleaning to avoid overwrite of cleaned log in loss scenarios to address Issue #271.
> * Correctly initialise cleaning position for late joining a stream. Issue #268.
> * Make clientLivenessTimeout configurable from Context.
> * Shadow samples into aeron-all JAR.
> * Support creating Agent threads via ThreadFactory to enable pinning.
> * Update to Agrona 0.5.4.
> * Update to ByteBuddy 1.4.20.
* 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)
