* Include actor system name in artery dir path to ease debugging leaks
* Base class name changed to make actor system autonaming work
* Add shutdown hook directly in transport start
* Wait for completion in shutdown hook (actual leak fix)
* Setting to configure where the flight recorder puts its file
* Run ArteryMultiNodeSpecs with flight recorder enabled
* More cleanup in exit hook, wait for task runner to stop
* Enable flight recorder for the cluster multi node tests
* Enable flight recorder for multi node remoting tests
* Toggle always-dump flight recorder output when akka.remote.artery.always-dump-flight-recorder is set
* deprecates awaitTermination, shutdown and isTerminated
* introduces a terminate-method that returns a Future[Unit]
* introduces a whenTerminated-method that returns a Future[Unit]
* simplifies the implementation by removing blocking constructs
* adds tests for terminate() and whenTerminated
* because it is not referentially transparent; normally we reserved parens for
side-effecting code but given how people thoughtlessly close over it we revised
that that decision for sender
* caller can still omit parens
- removed retry-window and related settings
- removed gate-invalid-addresses-for
- gate is now mandatory
- remoting has a dedicated dispatcher by default
- updated tests to work with changed timings
- added doc section for association lifecycle
* When actor system was restarted quickly the new system replied to
heartbeats and Terminated was never triggered for actors in old
system.
* Solved by sending an extra Watch system message when first hearbeat
is received for an address and when a change of system uid is detected.
