* fix shutdown race in sendControl, #21514
* the stack trace showed IllegalStateException: outboundControlIngress not initialized yet
via the call to sendControl
* that could happen if there is a shutdown at the same time, which is exactly what the test does
* it was actually caused by a merge mistake, but now it got even better
* countDown latch on shutdown
Currently, we use ByteStringBuilder to create a new ByteString instance,
which would not be quite efficient.
Instead of doing this, we can do as follows so that we can achieve better performance:
1. Seek the index of _last_ vector element we need to _take_
2. Find the number of characters left to take from the _last_ ByteString1 element.
3. Create ByteString based on the information we obtained from 1 and 2
Then we just need to create a new Vector[ByteString1] at most twice, which should be
better than the current implementation, i.e., _append_ a new element every time we check
bytestrings(Vector[ByteString1]) element, which ends up O(N) _append_ execution where _N_ is
the length of bytestrings.
* image-liveness-timeout must be less than the handshake-timeout,
otherwise the publication for the handshake will give up too early
when previous image is still considered alive
* they can't be stopped immediately because we want to send
some final message and we reply to inbound messages with `Quarantined`
* and improve logging
* after quarantine we should never start new inbound compressions for
that uid
* I noticed that the hit counting was creating new instances also for
quarantined, and thereby scheduling advertisments
* 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
