Subject [jira] [Created] (DERBY-6064) Failures in upgradeTests.changes10_9 related to index cardinality statistics
Date Fri, 01 Feb 2013 11:58:13 GMT
Kristian Waagan created DERBY-6064:

             Summary: Failures in upgradeTests.changes10_9 related to index cardinality statistics
                 Key: DERBY-6064
                 URL: https://issues.apache.org/jira/browse/DERBY-6064
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions:
            Reporter: Kristian Waagan
            Assignee: Kristian Waagan

The upgrade test fails when run with 10.8.3. The reason is that a fix has been backported
to 10.8.3, and older branches back to 10.3, and this fix invalidates assumptions made in some
of the tests in Changes10_9.

Example of failures:

As a side note, I'm wondering if we don't have good enough routines to make sure we run the
upgrade tests with maintenance releases on older branches before releasing them. I don't know
if we can avoid this situation in general, that would at least require very careful consideration
on how to write the upgrade test.
