Subject [jira] Updated: (DERBY-3844) ASSERT failure in BasePage.unlatch() when running LobStreamsTest
Date Fri, 12 Feb 2010 08:54:28 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3844?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kristian Waagan updated DERBY-3844:
-----------------------------------

    Attachment: derby-3844-1b-disallow_multiple_accesses.diff

Patch 1b fixes errors in jdbcapi.ClosedObjectTest discovered when running the full regression
tests by moving the call to useStreamOrLOB to after the check for if the result set is open
(failed with NPE because the meta data is cleared when closing).

Patch ready for review, re-running tests.

> I saw this failure when running suites.All to test the patch nested_transaction_v2.diff
which is posted on DERBY-3693. The failure did not occur when I reran the test, and I don't
believe the patch should have any effect on the code that failed. The ASSERT that is triggered
is this one (which indicates that we're trying to unlatch a page that's not latched):
> 		if (SanityManager.DEBUG) {
> 			SanityManager.ASSERT(isLatched());
