Knut Anders Hatlen updated DERBY-5406:
--------------------------------------
Issue & fix info: Patch Available
Setting the patch available flag since the patch passes the regression tests,
and the problems still seen with the stress test for this issue are also seen
without the patch.
> 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: 10.8.2.2, 10.9.0.0
> Reporter: Knut Anders Hatlen
> Assignee: Knut Anders Hatlen
> Attachments: CompressAndPrepare.java,
> d5406-1a-detect-invalidation-during-compilation.diff, 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.
