EJB3/Hibernate/JBoss Cache intergration broken in EJB3 trunk

by Brian Stansberry

Carlo, FYI, there are a bunch of EJB3 clustered entity test failures in AS trunk due to a bad interaction between Hibernate 3.2.4.SP1 and JBoss Cache 2.0.0. Basically, this is a temporary mismatch between Hibernate and JBC. There's work in Hibernate Core's trunk for the 3.3 release that can let us resolve this, but for now the tests are going to fail. Problem is the integration layer ends up calling the JBC putForExternalRead() method when it needs to cache something in the "UpdateTimestampsCache". JBC treats a calls to this method as a no-op if the cache node in question already exists. This is new behavior in JBC 2.0. It's the necessary and intended behavior when the method is called for caching entities and collections. But when it's called for the UpdateTimestampsCache, it causes problems. The Hibernate 3.3. codebase gives us the flexibility to call a different method for the UpdateTimestampsCache call; to fix the problem we need determine the exact behavior we want for the UpdateTimestampsCache call and make the appropriate call to JBC. -- Brian Stansberry Lead, AS Clustering JBoss, a division of Red Hat brian.stansberry(a)redhat.com

buddy replication test failures in 1.4.x

by Galder Zamarreno

Hi, I have gone through some of the failures I'm getting when running the test suite for 1.4.x: * Some buddy replication tests show this test failures: junit.framework.AssertionFailedError: buddy's list of groups it participates in should contain data owner's group name at org.jboss.cache.buddyreplication.BuddyReplicationTestsBase.assertIsBuddy(BuddyReplicationTestsBase.java:280) Earlier in the test, you can see this Exception: org.jboss.cache.buddyreplication.BuddyNotInitException: Not yet initialised at org.jboss.cache.buddyreplication.BuddyManager.handleAssignToBuddyGroup(BuddyManager.java:450) at org.jboss.cache.TreeCache._remoteAssignToBuddyGroup(TreeCache.java:5372) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jgroups.blocks.MethodCall.invoke(MethodCall.java:330) This failure seems to be a related to a timing issue, when a node requests another to join the buddy group but this node is still in the initialisation process, BM.init(). More precisely, the code is broadcasting buddy pool membership, and at that point a, request to joing the buddy groups occurs. The channel is connected before the buddy manager is initialised, so there's always the possibility of receiving messages before buddy manager has finished initialising. Various solutions that come to my mind: 1.- staggering cache starts 2.- wait for a little bit before throwing BuddyNotInitException seeing that the broadcasting task could be lengthy (i.e. one of the nodes fails to respond as the call is synchronous), maybe wait for buddyCommunicationTimeout? IMO, 2 is preferred. -- Galder Zamarreño Sr. Software Maintenance Engineer JBoss, a division of Red Hat
