Concurrent modification problem with group commit.

    XMLWordPrintable

    Details

    • Type: Bug
    • Status: Done
    • Resolution: Done
    • Affects Version/s: BIGDATA_RELEASE_1_5_0
    • Fix Version/s: None
    • Component/s: B+Tree

      Description

      The HA test suite now runs nearly green when group commit is enabled. However a few tests are hitting an NPE. This would appear to be a problem with copy-on-write causing the clear of the data reference inside of a Leaf during SPARQL UPDATE processing.

      To replicate, run the HA test suite after modifying the following line in the HAJournal-[ABCDE].config files. This enables group commit for all HAJournal instances used by the test suite.

            new NV(com.bigdata.journal.Journal.Options.GROUP_COMMIT,System.getProperty("groupCommit","true")),
