[infinispan-issues] [JBoss JIRA] Updated: (ISPN-575) Wrong reordering of data when using Flag.SKIP_LOCKING and having a cache store enabled

Wrong reordering of data when using Flag.SKIP_LOCKING and having a cache store enabled -------------------------------------------------------------------------------------- Key: ISPN-575 URL: https://jira.jboss.org/browse/ISPN-575 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 4.0.0.Final, 4.1.0.CR2 Reporter: Sanne Grinovero Assignee: Mircea Markus Priority: Critical Fix For: 5.1.0.BETA1, 5.1.0.Final Attachments: [ISPN-575]_(Corruption_in_data_when_using_a_permanent_store)_Extra_debugging_info_.patch, ISPN-575-previewOfTest-dontapply.patch, more_logs.patch We verified the issue while using the Lucene Directory; using the Directory under stress leads to no issues even during long running tests of several hours. To verify the Lucene Directory under stress, use org.infinispan.lucene.profiling.PerformanceCompareStressTest. The same exact test - but having a jdbc store enabled - breaks: org.infinispan.lucene.profiling.CacheStoreStressTest (*) Lucene's error says "invalid checksum", the truth is that the checksum data is missing as there where two consecutive put operations: one containing the correct data but missing the checksum signature, and then again putting the same data but with the correct signature; both puts are using SKIP_LOCKING, and it appears that some readers in other threads - which definitely start after the second put - are getting the first unsigned values (under load only - must be a race condition). * The CacheStoreStressTest was committed with ISPN-590 as #2187, but same commit also works around the issue in the Lucene implementation, so keep the implementation at a previous revision.
