[infinispan-issues] [JBoss JIRA] (ISPN-2721) Issue with conditional operations and verisioning

Issue with conditional operations and verisioning ------------------------------------------------- Key: ISPN-2721 URL: https://issues.jboss.org/browse/ISPN-2721 Project: Infinispan Issue Type: Sub-task Reporter: Mircea Markus Assignee: Galder Zamarreño Fix For: 5.2.0.CR2 Attachments: SimpleConditionalOperationsWriteSkewTest.java The problem: - repeatable read cache with write skew check enabled - a conditional operation (e.g. replace) executes and is not successful (e.g. because the value doesn't exist) - during the successful operation the entry is written to the container with a null version. (i.e. the previous version is erased). That is well bad! Suggested solution: - for such entries that were not modified (isChanged==false) the value should not be re-written to the container OR Attached is a unit test capturing the problem.
