Transaction rolled back but returns successful response ------------------------------------------------------- Key: ISPN-5158 URL: https://issues.jboss.org/browse/ISPN-5158 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 7.1.0.Beta1 Reporter: Radim Vansa Assignee: Dan Berindei Priority: Critical Attachments: tx.txt, views.txt When the cluster is merging, it is possible that a node is removed from the view although it is still responsive. Eventually the cluster is merged correctly, but since the node is reported as missing from the view, transaction originating from this node is rolled back. {code} 10:01:36,116 TRACE [org.infinispan.interceptors.TxInterceptor] (remote-thread-151) Rolling back remote transaction GlobalTransaction:<edg-perf02-39415>:28106:remote because either already completed(false) or originator no longer in the cluster(true). {code} However, even after this a successful response is sent to the originator: {code} 10:01:36,119 TRACE [org.infinispan.remoting.InboundInvocationHandlerImpl] (remote-thread-151) About to send back response null for command PrepareCommand {modifications=[PutKeyValueCommand{key=key_0000000000001318, value=[19 #1: 1195, ], flags=[SKIP_CACHE_LOAD, SKIP_REMOTE_LOOKUP], putIfAbsent=false, valueMatcher=MATCH_ALWAYS, metadata=EmbeddedMetadata{version=null}, successful=true}], onePhaseCommit=false, gtx=GlobalTransaction:<edg-perf02-39415>:28106:remote, cacheName='testCache', topologyId=47} {code} Originator then expects that the transaction was successfully prepared: {code} 10:01:36,124 TRACE [org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher] (DefaultStressor-9) Responses: [sender=edg-perf01-36235, received=true, suspected=false] [sender=edg-perf03-24110, received=true, suspected=false] 10:01:36,135 TRACE [org.infinispan.transaction.TransactionCoordinator] (DefaultStressor-9) Committing transaction GlobalTransaction:<edg-perf02-39415>:28106:local {code}
