[jboss-jira] [JBoss JIRA] Closed: (JBCACHE-1234) Region activation requests partial state transfer from wrong nodes

Region activation requests partial state transfer from wrong nodes ------------------------------------------------------------------ Key: JBCACHE-1234 URL: http://jira.jboss.com/jira/browse/JBCACHE-1234 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Affects Versions: 2.0.0.GA, 1.4.1.SP7, 2.1.0.CR2 Reporter: Brian Stansberry Assigned To: Brian Stansberry Priority: Critical Fix For: 1.4.1.SP8, 2.1.0.GA When requesting partial state transfer as part of activating a region, we are asking for state from the wrong nodes: // Get the state from each DataOwner and integrate in their // respective buddy backup cache List<Address> buddies = buddyManager.getBuddyAddresses(); for (Address buddy : buddies) { List<Address> sources = new ArrayList<Address>(1); sources.add(buddy); Fqn buddyRoot = BuddyManager.getBackupFqn(buddy, fqn); subtreeRoot = cache.findNode(buddyRoot); .... cache.fetchPartialState(sources, fqn, subtreeRoot.getFqn()); } } BuddyManager.getBuddyAddresses() returns the nodes who are backing up *our* data, not those for whom we are serving as a buddy. We want the state for the latter. This comes from the package-private BuddyManager.buddyGroupsIParticipateIn field, so BuddyManager is going to have to expose that somehow.
