* WIP early preview of moving compressions ownership to Decoder
* Compression table created in transport, but owned by Decoder
Added test for restart of inbound stream
* =art snapshot not needed in HeavyHitters since owned by Decoder
* Make decoding release the envelope so it doesn't leak memory
* Create two different configurations, Standard and RemoteInstrument
* Create Serilaizer and RemoteInstrument that doesn't allocate memory
* =act clean up ByteString#drop(...)
Current implementation has a good algorithm but seems a little bit complicated.
Clening-up does not suffer the performance (actually seems to have the better
performance when dropping(N-1)) where N is the length, and is easy to understand
almost the same algorithm now.
* Change private[akka] to priavte
* Rename go(...) and some variables
They should be easy for us to understand what they are.
* Add benchmark of ByteString#drop(...)
* 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
* 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
* outbound compression is now immutable, by simply using
CompressionTable[ActorRef] and CompressionTable[String]
* immutable outbound compression will make it possible to use
them from multiple Encoder instances, when we add several lanes
for parallel serialization
* outbound compression tables not shared via AssociationState
* the advertised tables are sent to the Encoder stage via async
callback, no need to reference the tables in other places than
the Encoder stage, no more races via shared mutable state
* when outbound stream is started or restarted it can start out
without compression, until next advertisement is received
* ensure outbound compression is cleared before handshake is signaled complete
* =art now correctly compresses and 2 table mode working
* =art AGRESSIVELY optimising hashing, not convienved about correctness yet
* fix HandshakeShouldDropCompressionTableSpec
* Provide shorter aliases for the ActorRefProviders #20649
* Use the new actorefprovider aliases throughout code and docs
* Cleaner alias replacement logic
