Subject [jira] Updated: (DERBY-3850) Remove unneeded workarounds for DERBY-177 and DERBY-3693
Date Fri, 05 Sep 2008 18:16:44 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-3850:
--------------------------------------

    Attachment: d3850-predicatesIntoViews.stat
                d3850-predicatesIntoViews.diff

It turns out that the workaround for bug 4821 in predicatesIntoViews.sql wasn't needed anymore.
I removed the commit and the test finished in about 15 seconds, same as if it ran unchanged.
When I reverted the fix for DERBY-3693, the modified test needed 4 minutes 15 seconds to finish.

Attaching a patch that removes the workaround from the test and from the canon.

> After the fix for DERBY-177 and DERBY-3693 was committed, these code clean-ups could
be performed:
>   - remove workaround for DERBY-177 in the tests (search for the string "DERBY-177" to
find them)
>   - remove logic to prevent waiting for table locks in SPSDescriptor.updateSYSSTATEMENTS()
since the new mechanism will prevent waiting for all types of locks
