Transactions committed immediately before cache stop can block shutdown ----------------------------------------------------------------------- Key: ISPN-5507 URL: https://issues.jboss.org/browse/ISPN-5507 Project: Infinispan Issue Type: Bug Components: Core, Test Suite - Core Affects Versions: 7.2.1.Final, 8.0.0.Alpha1 Reporter: Dan Berindei Priority: Blocker Labels: testsuite_stability Fix For: 8.2.0.Alpha1 This is causing random failures in {{DistributedEntryRetrieverTxTest.verifyNodeLeavesBeforeGettingData}}. The test inserts some values into the cache, starts an iteration, and then kills one of the nodes. In rare instances, the killed cache only receives the TxCompletionCommand for one of the writes after it started the shutdown, and ignores it. That leaves the remote tx on-going, and {{TransactionTable.shutDownGracefully()}} blocks for 30 seconds - causing a {{TimeoutException}} elsewhere in the test. {noformat} 10:52:18,129 TRACE (remote-thread-NodeAM-p12133-t6:) [CommandAwareRpcDispatcher] About to send back response SuccessfulResponse{responseValue=null} for command CommitCommand {gtx=GlobalTransaction:<NodeAL-45757>:22325:remote, cacheName='org.infinispan.iteration.DistributedEntryRetrieverTxTest', topologyId=4} 10:52:18,129 TRACE (testng-DistributedEntryRetrieverTxTest:) [JGroupsTransport] dests=[NodeAM-45518, NodeAL-45757], command=TxCompletionNotificationCommand{ xid=null, internalId=0, topologyId=4, gtx=GlobalTransaction:<NodeAL-45757>:22325:local, cacheName=org.infinispan.iteration.DistributedEntryRetrieverTxTest} , mode=ASYNCHRONOUS, timeout=15000 10:52:18,133 DEBUG (testng-DistributedEntryRetrieverTxTest:) [CacheImpl] Stopping cache org.infinispan.iteration.DistributedEntryRetrieverTxTest on NodeAM-45518 10:52:18,133 TRACE (OOB-2,NodeAM-45518:) [GlobalInboundInvocationHandler] Attempting to execute CacheRpcCommand: TxCompletionNotificationCommand{ xid=null, internalId=0, topologyId=4, gtx=GlobalTransaction:<NodeAL-45757>:22325:local, cacheName=org.infinispan.iteration.DistributedEntryRetrieverTxTest} [sender=NodeAL-45757] 10:52:18,133 TRACE (OOB-2,NodeAM-45518:) [GlobalInboundInvocationHandler] Silently ignoring that org.infinispan.iteration.DistributedEntryRetrieverTxTest cache is not defined 10:52:18,133 DEBUG (testng-DistributedEntryRetrieverTxTest:) [TransactionTable] Wait for on-going transactions to finish for 30 seconds. 10:52:48,139 WARN (testng-DistributedEntryRetrieverTxTest:) [TransactionTable] ISPN000100: Stopping, but there are 0 local transactions and 1 remote transactions that did not finish in time. 10:52:48,386 ERROR (testng-DistributedEntryRetrieverTxTest:) [UnitTestTestNGListener] Test verifyNodeLeavesBeforeGettingData(org.infinispan.iteration.DistributedEntryRetrieverTxTest) failed. java.lang.IllegalStateException: Thread already timed out waiting for event pre_send_response_released at org.infinispan.test.fwk.CheckPoint.trigger(CheckPoint.java:131) at org.infinispan.test.fwk.CheckPoint.trigger(CheckPoint.java:116) at org.infinispan.iteration.DistributedEntryRetrieverTest.verifyNodeLeavesBeforeGettingData(DistributedEntryRetrieverTest.java:105) {noformat}
