Subject [jira] Updated: (DERBY-4837) Prepare lang.UpdateStatisticsTest for automatic index statistics generation
Date Fri, 10 Dec 2010 16:43:01 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4837?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Kristian Waagan updated DERBY-4837:

    Attachment: derby-4837-2a-disable_auto_istat.diff

Attaching patch 2a, which disables automatic index statistics update.

I removed the second TODO, because the relevant code will still be run even though the automatic
update is disabled.
Patch ready for review.

> Rewrite test to use the new index stats helper class.
> Due to timing issues, automatic index statistics generation should be disabled for this
> Note that the test case testNoExclusiveLockOnTable should be run with autogen enabled,
as it covers an issue with the data dictionary access pattern (discovered during prototyping).
