Subject [jira] Issue Comment Edited: (DERBY-5037) Assertion failure from index-stat-thread when running AutomaticIndexStatisticsTest
Date Tue, 15 Feb 2011 17:06:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5037?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12994880#comment-12994880

--------------------------------------------------------------------

It sounds reasonable to me that the istat daemon simply ignores any exceptions if the database
is being shut down under its feet. However, I think the patch also ignores exceptions when
statistics are updated explicitly (e.g., by using ALTER TABLE or SYSCS_UPDATE_STATISTICS)
because of the changes in runExplicitly(). We should probably continue raising exceptions
if these explicit calls fail during shutdown.

The test itself completes successfully:
