[infinispan-issues] [JBoss JIRA] (ISPN-3677) With optimistic TX, conditional commands may wrongly succeed

With optimistic TX, conditional commands may wrongly succeed ------------------------------------------------------------ Key: ISPN-3677 URL: https://issues.jboss.org/browse/ISPN-3677 Project: Infinispan Issue Type: Bug Components: Core API Affects Versions: 6.0.0.CR1 Reporter: Radim Vansa Assignee: Mircea Markus Priority: Critical Situation with optimistic TX, originator = entry's primary owner: 1. The conditional check suceeds when the command is executed 2. In TxDistributionInterceptor, ignorePreviousValue is set to true 3. The command is then enlisted in the modifications list with the ignorePreviousValue set to true 4. During the prepare/commit phase the command ignores the condition Result: Two commands, replace(key, A, B), replace(key, A, C) may both overwrite the entry (and the one committed later wins, actually overwriting B instead of A).
