[jbosscache-issues] [JBoss JIRA] Commented: (JBCACHE-1527) LockParentForChildInsertRemove ignored with PessimisticLocking

LockParentForChildInsertRemove ignored with PessimisticLocking -------------------------------------------------------------- Key: JBCACHE-1527 URL: https://jira.jboss.org/jira/browse/JBCACHE-1527 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Components: Locking Affects Versions: 3.1.0.GA Reporter: Brian Stansberry Assignee: Manik Surtani Fix For: 3.2.0.GA Attachments: DGTest.java, JBCACHE-1527.patch From looking at the JBC 3 code, it seems the LockParentForChildInsertRemove configuration is no longer respected for pessimistic locking. I can't trace any path from the property in Configuration to code that uses it. PessimisticLockInterceptor.handlePutCommand, handleMoveCommand and handleRemoveNodeCommand all always tell the lock manager to lock parents. handleEvictFqnCommand always tells the lock manager not to lock parents. This is causing failures in buddy replication testing when nodes join/leave clusters under load. There's a lot of data gravitation plus stuff like migrating defunct backup trees to "DEAD" regions. Too much contention for parent level locks. Plus locking on the structural parent to add/remove session nodes will suck for the session caching use case.
