[jbosscache-issues] [JBoss JIRA] Commented: (JBCACHE-1445) Problem with cleanup after data gravitation

Problem with cleanup after data gravitation ------------------------------------------- Key: JBCACHE-1445 URL: https://jira.jboss.org/jira/browse/JBCACHE-1445 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Components: Buddy Replication Affects Versions: 3.0.0.GA Reporter: Brian Stansberry Assignee: Manik Surtani Priority: Critical Fix For: 3.0.1.CR1, 3.0.1.GA JBoss AS web session replication soak testing is showing issues with buddy replication. One of the failure modes seems to show leftover data remaining in the main tree for a session's former owner after the session has failed over to another node. I've taken this issue as a good chance to start filling in the test infrastructure in the org.jboss.cache.integration package. Test org.jboss.cache.integration.websession.BuddyReplicationFailoverTest.testFailoverAndFailBack() shows the issue. I think some of the tests in the buddyreplication package should be checking for this; not sure why they pass. Likely some subtle variation in config or something. The test uses a lot of infrastructure to mock what the AS does. But underneath it all, the commands to the cache come down to: node0: getData(fqn) w/ data gravitation option // nothing there put(fqn, map) // establishes session put(fqn, map) // updates session node3 getData(fqn) w/ data gravitation option // gravitates session put(fqn, map) // updates session At this point the cache contents are examined, and the original node in node0's main tree is still present. A buddy backup node, data owner node3, is also present on node0, as it should be.
