L1 and early invalidation leaves inconsistent state --------------------------------------------------- Key: ISPN-2965 URL: https://issues.jboss.org/browse/ISPN-2965 Project: Infinispan Issue Type: Bug Components: Distributed Cache, Transactions Affects Versions: 5.2.1.Final Reporter: Sebastian Tusk Assignee: Adrian Nistor Labels: 5.2.x Fix For: 5.3.0.Final In a distributed transactional cache with L1 enabled I can observe the following. Prepare cache by adding an entry with Cache.put( k, v1 ). 1. Node B starts with adding a changed value. Cache.put( k, v2 ) 2. Node B TxDistributionInterceptor.visitPrepareCommand flushL1Caches sends invalidations. 3. Node A calls Cache.get( k ) retrieves v1 and stores this value in L1. 4. Node B proceeds with transaction. The result is that Node A answers subsequent Cache.get(k) with v1 and Node B answers with v2. It seems the invalidation is either send to early or must be synchronized in some way with the transaction.
