L1 entry added by ST when already invalidated --------------------------------------------- Key: ISPN-3838 URL: https://issues.jboss.org/browse/ISPN-3838 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 6.0.0.Final Reporter: Radim Vansa Assignee: William Burns Priority: Critical Labels: 620 Non-transactional cache with L1 enabled. Node A is losing ownership of an entry, the entry is not removed during ST but is going to L1. 1. ST builds the invalidation command, EntryWrapping interceptor starts committing all the entries 2. Write on primary owner (B) occurs 3. A gets the InvalidateL1Command, removes the ImmortalCacheEntry from data container (as it does not own the entry anymore) 4. The ST invalidation command commits the MortalCacheEntry with old value, storing it into the data container. Result: Outdated value is in L1 cache. As the entry is not locked during the ST, it can be committed as MortalCacheEntry only if it was not changed (removed and possibly then cached again with different value). (I understand that this wouldn't be easy to implement as the check is not to be executed in perform, but during the actual commit - and atomically in the container.)
