Subject [jira] Updated: (DERBY-2432) Unimplemented transaction time out for XA transactions may cause that locks will not be released when client terminates outside a unit of work.
Date Thu, 14 Jun 2007 13:06:28 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2432?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Julius Stroffek updated DERBY-2432:
-----------------------------------

    Attachment: d2432_v4.stat
                d2432_v4.diff

I have created an additional patch.

changes:
XATransactionState:
- Added a timeout task cancellation to xa_prepare() method.
- Common code from xa_commit/rollback/prepare moved
  to xa_finalize()
- Some more comments added to cancel()

I am running the tests now. However, the change should not affect the tests. I'll post the
results after tests will finish.
