From 5e80bd97f258ebcf041276daa33b381db31b1283 Mon Sep 17 00:00:00 2001 From: Patrik Nordwall Date: Mon, 20 Nov 2017 15:15:17 +0100 Subject: [PATCH] Stop unused Artery outbound streams, #23967 * fix memory leak in SystemMessageDelivery * initial set of tests for idle outbound associations, credit to mboogerd * close inbound compression when quarantined, #23967 * make sure compressions for quarantined are removed in case they are lingering around * also means that advertise will not be done for quarantined * remove tombstone in InboundCompressions * simplify async callbacks by using invokeWithFeedback * compression for old incarnation, #24400 * it was fixed by the other previous changes * also confirmed by running the SimpleClusterApp with TCP as described in the ticket * test with tcp and tls-tcp transport * handle the stop signals differently for tcp transport because they are converted to StreamTcpException * cancel timers on shutdown * share the top-level FR for all Association instances * use linked queue for control and large streams, less memory usage * remove quarantined idle Association completely after a configured delay * note that shallow Association instances may still lingering in the heap because of cached references from RemoteActorRef, which may be cached by LruBoundedCache (used by resolve actor ref). Those are small, since the queues have been removed, and the cache is bounded. --- .../remote/artery/SendQueueBenchmark.scala | 2 +- .../cluster/LargeMessageClusterSpec.scala | 25 +- .../artery/aeron/AeronStreamLatencySpec.scala | 5 +- .../mima-filters/2.5.9.backwards.excludes | 14 + akka-remote/src/main/resources/reference.conf | 15 + .../akka/remote/artery/ArterySettings.scala | 5 + .../akka/remote/artery/ArteryTransport.scala | 56 ++- .../akka/remote/artery/Association.scala | 443 ++++++++++++++---- .../scala/akka/remote/artery/Codecs.scala | 120 ++--- .../scala/akka/remote/artery/Control.scala | 13 +- .../remote/artery/FlightRecorderEvents.scala | 10 + .../scala/akka/remote/artery/Handshake.scala | 1 + .../scala/akka/remote/artery/SendQueue.scala | 9 +- .../remote/artery/SystemMessageDelivery.scala | 20 +- .../aeron/ArteryAeronUdpTransport.scala | 23 +- .../artery/compress/InboundCompressions.scala | 141 +++--- .../artery/tcp/ArteryTcpTransport.scala | 36 +- .../remote/artery/EnvelopeBufferSpec.scala | 1 + .../artery/InboundControlJunctionSpec.scala | 4 + .../artery/OutboundIdleShutdownSpec.scala | 209 +++++++++ .../akka/remote/artery/SendQueueSpec.scala | 30 +- .../artery/SystemMessageDeliverySpec.scala | 43 +- .../akka/remote/artery/TestContext.scala | 4 +- 23 files changed, 909 insertions(+), 320 deletions(-) create mode 100644 akka-remote/src/test/scala/akka/remote/artery/OutboundIdleShutdownSpec.scala diff --git a/akka-bench-jmh/src/main/scala/akka/remote/artery/SendQueueBenchmark.scala b/akka-bench-jmh/src/main/scala/akka/remote/artery/SendQueueBenchmark.scala index 5af52d0ea1..3d00630cb9 100644 --- a/akka-bench-jmh/src/main/scala/akka/remote/artery/SendQueueBenchmark.scala +++ b/akka-bench-jmh/src/main/scala/akka/remote/artery/SendQueueBenchmark.scala @@ -115,7 +115,7 @@ class SendQueueBenchmark { val burstSize = 1000 val queue = new ManyToOneConcurrentArrayQueue[Int](1024) -
