[jboss-jira] [JBoss JIRA] Created: (JBCACHE-1298) Removal of non-existent node leaves invalid tombstone on remote nodes

Removal of non-existent node leaves invalid tombstone on remote nodes --------------------------------------------------------------------- Key: JBCACHE-1298 URL: http://jira.jboss.com/jira/browse/JBCACHE-1298 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Components: Optimistic Locking, Replication Reporter: Brian Stansberry Assigned To: Manik Surtani Fix For: 2.1.0.CR4 Problem with optimistic locking and invalidation: Say node with Fqn "/a" doesn't exist in memory in any cache in cluster. On node1, call to cache.removeNode("/a") is made. This is a valid call even though "/a" doesn't exist in the local cache -- caller wants it removed/invalidated across the cluster. This results in an invalidate() call around the cluster for "/a". Since "/a" doesn't exist, no DataVersion is passed with the call. On other nodes in the cluster, the invalidate() method detects that "/a" doesn't exist locally. So, invalidate() creates a tombstone for "/a". Tombstone gets initialized with a DefaultDataVersion. Since no other DataVersion was passed with the call, the tombstone gets left with that DefaultDataVersion. Now on node2 an attempt is made to do a put to "/a", passing in a DataVersion. The put fails with a version conflict due to the presence of the tombstone. InvalidationInterceptorTest.testAddOfDeletedNonExistent() shows the problem. This same issue is coming up in the Hibernate/JBC integration tests. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
