race condition in DistributionManagerImpl ----------------------------------------- Key: ISPN-925 URL: https://issues.jboss.org/browse/ISPN-925 Project: Infinispan Issue Type: Bug Components: Core API, State transfer Affects Versions: 4.2.0.Final Reporter: Mircea Markus Assignee: Mircea Markus Priority: Critical Fix For: 4.2.1.Final, 5.0.0.ALPHA3, 5.0.0.Final This is causing StateTransferLargeObjectTest to fail intermittently (about 1/500 runs). Nasty race condition in DistributionManagerImpl 1. if a node leaves then the new consistent hash is first set ( consistentHash = ConsistentHashHelper.removeAddress(consistentHash, leaver, configuration, topologyInfo);) 2. then an InvertedLeaveTask is triggered if needed 3 this would add the leaver to DMI.levers and set the rehashInProgress flag of DMImpl to true (RehashTask.call) Now if a get call happens between 1 and 3 then then the the system would not go remotley. The "go remotly if there's a rehash going on" condition happens in DistInterceptor.visitGetKeyValueCommand: boolean isRehashInProgress = !dm.isJoinComplete() || dm.isRehashInProgress(); if the isRehashInProgress is set to true then we go remotly even if the key is mapped to the local node.
