[jboss-jira] [JBoss JIRA] Created: (JBMESSAGING-1879) Duplicated Message delivery in message sucking process

Duplicated Message delivery in message sucking process ------------------------------------------------------ Key: JBMESSAGING-1879 URL: https://issues.jboss.org/browse/JBMESSAGING-1879 Project: JBoss Messaging Issue Type: Bug Components: JMS Clustering Affects Versions: 1.4.8.GA, 1.4.0.SP3.CP12 Reporter: Yong Hao Gao Assignee: Yong Hao Gao Priority: Critical Fix For: 1.4.0.SP3.CP13, 1.4.8.SP1 If a message is sucked over to another node and at the same time failover happens at the source node, the source node will try to claim back messages in 'S' (sucking) states. If the said message is claimed back, the message won't get sucked because eventually the moveMessage operation on the DB will fail. But in JDBCPersistenceManager.moveReference() it doesn't properly handle this, resulting in the message can be sucked twice. Also there is a flaw in JDBCPersistenceManager.claimMessagesInSuck(long), this statement: msgIDs.add(new ReferenceInfo(msgId, deliveryCount, sched)); should be: if (rows == 1) { msgIDs.add(new ReferenceInfo(msgId, deliveryCount, sched)); } without the if condition, a sucked message also can be re-delivered the second time. -- This message is automatically generated by JIRA.
