[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-315) Break locks for state transfer

Break locks for state transfer ------------------------------ Key: JBCACHE-315 URL: http://jira.jboss.com/jira/browse/JBCACHE-315 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Bela Ban Assigned To: Vladimir Blagojevic Priority: Critical Fix For: 2.1.0.GA, 2.1.0.CR1 State transfer needs to acquire a lock on the root to make sure all existing TXs have been completed. However, when a TX takes more time than the lock acquisition timeout, state transfer will fail. Therefore, we need to forcefully acquire the locks for the state transfer by force-releasing the existing locks, and rolling back all TXs that held those locks. This will ensure that state transfer always succeeds, at the expense of some rolled back TXs. We need to investigate how this works with optimistic locking
