Subject [jira] [Created] (DERBY-5406) Intermittent failures in CompressTableTest and TruncateTableTest
Date Fri, 09 Sep 2011 09:55:09 GMT
Intermittent failures in CompressTableTest and TruncateTableTest
----------------------------------------------------------------

                 Key: DERBY-5406
                 URL: https://issues.apache.org/jira/browse/DERBY-5406
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.8.1.6, 10.9.0.0
            Reporter: Knut Anders Hatlen


The test cases CompressTableTest.testConcurrentInvalidation() and TruncateTableTest.testConcurrentInvalidation()
fail intermittently with errors such as:

ERROR XSAI2: The conglomerate (2,720) requested does not exist.

The problem has been analyzed in the comments on DERBY-4275, and a patch attached to that
issue (invalidation-during-compilation.diff) fixes the underlying race condition. However,
that patch only works correctly together with the fix for DERBY-5161, which was backed out
because it caused the regression DERBY-5280.

We will therefore need to find a way to fix DERBY-5161 without reintroducing DERBY-5280 in
order to resolve this issue.
