Subject [jira] [Updated] (DERBY-5406) Intermittent failures in CompressTableTest and TruncateTableTest
Date Wed, 01 Feb 2012 18:07:01 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5406?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Mike Matrigali updated DERBY-5406:

    Fix Version/s:
         Assignee: Knut Anders Hatlen  (was: Mike Matrigali)

backported change from trunk to 10.8.  resetting original owner.  

To backport farther back, this change may depend on other changes, as is discussed in previous
comments of this issue.  

Hope is that this backport will elinate current intermittent failures in the nightly tests
against 10.8 as they did for trunk.   At this point since this issue is closed any new failures
seen in these 2 tests in versions that have the fix should be logged in a new issue and can
be linked back to this one

d5406-1b.diff, d5406-2a-invalidate-self.diff, d5406-3a.diff, d5406-4a-push-retry-logic.diff,
> 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.
