* 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)
* comprehensive integration test that revealed many bugs
* confirmations of manifests were wrong, at two places
* using wrong tables when system is restarted, including
originUid in the tables with checks when receiving advertisments
* close (stop scheduling) of advertisments when new incarnation,
quarantine, or restart
* cleanup how deadLetters ref was treated, and made it more robust
* make Decoder tolerant to decompression failures, can happen in
case of system restart before handshake completed
* give up resending advertisment after a few attempts without confirmation,
to avoid keeping outbound association open to possible dead system
* don't advertise new table when no inbound messages,
to avoid keeping outbound association open to possible dead system
* HeaderBuilder could use manifest field from previous message, added
resetMessageFields
* No compression for ArteryMessage, e.g. handshake messages must go
through without depending on compression tables being in sync
* improve debug logging, including originUid
* 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
* need to use a shared media driver to get the cpu usage
at a reasonable level
* also changed to SleepingIdleStrategy(1 ms) when cpu-level=1
not needed for the test to pass, but can be good to make level 1
more extreme
* Don't quarantine the other system when receiving the Quarantined message,
since that will result cluster member removal and can result in
forming two separate clusters (cluster split).
* Instead, the downing strategy should act on ThisActorSystemQuarantinedEvent, e.g.
use it as a STONITH signal.
* The previous approach was based on sending the
test commands to the active stages themselves and let
them keep track of the state.
* The problem with that is that Association/OutboundTestStage
that is created afterwards will not have the right state.
Similar problems can occur for restarts.
* Instead using thread-safe mutable state that is
updated directly and used by all test stages.
* system messages in flight should not trigger premature quarantine
in case of longer network partitions, therefore we keep the control
stream alive
* add give-up-system-message-after property that is used by both
SystemMessageDelivery and AeronSink in the control stream
* also unwrap SystemMessageEnvelope in RemoteDeadLetterActorRef
* skip sending control messages after shutdown, can be triggered
by scheduled compression advertisment
