Subject [jira] Commented: (DERBY-1764) Rewrite stress.multi as a JUnit test
Date Sat, 19 Jul 2008 00:01:31 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1764?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12614917#action_12614917

Kathey Marsden commented on DERBY-1764:
---------------------------------------

I looked a little at the Windows failure removing the database after the encrypted run.  
I verified that the database is being shutdown normally (we get the database shutdown message).
 I tried inserting a sleep for 10 seconds after the shutdown and before the directory removal.
  I tried inserting a gc() after the shutdown and before removal and still got the same failure.
  It seems there is some sort of bug shutting down the encrypted database that it hangs onto
resources.  I have been running with IBM 1.5.  Monday I will try with other JVM's and also
see if I can get a reproducible test case for the removal problem outside of this test.  
If anyone has any ideas what is going on or other tips I would most appreciate it.  I can
reproduce two out of three times with the multi.StressMulti10x1 test.

One more thing. The file we are unable to remove seems to vary, for instance on one run it
was:
1) StressMultiTest:encryptedjunit.framework.AssertionFailedError: C:\test\system\singleUse\oneuse0\seg0\c420.dat
and on another
1) StressMultiTest:encryptedjunit.framework.AssertionFailedError: C:\test\system\singleUse\oneuse0\seg0\c400.dat

Don't know if that makes any difference.

> Currently, stress.multi consists of a number of sql scripts that are run in ij. It often
fails with cryptic error messages, and since it uses ij, there is often no stack trace. It
would be very useful to rewrite the test in JUnit so that we can get better error messages
and stack traces when it fails.
