Description Gordon Sim 2008-08-26 04:51:44 EDT
+++ This bug was initially created as a clone of Bug #458656 +++

The resonse for dtx.recover should include a list of all the xids currently in the prepared state; at present it only includes those that were in prepared state at time of last recovery.

--- Additional comment from kim.vdriet@redhat.com on 2008-08-14 14:40:04 EDT ---

The call to BdbMessageStore::collectPreparedXids() was using the prepared list obtained at time of recovery, but this call needs to provide a current list, no matter when called. The ability to ignore transactions when reading was added to class rmgr, and a subclass of JournalImpl (called TplJournalImpl) was created which implements the ignore as standard practice when calling read. This enables reads of pending transactions from this list. Now BdbMessageStore::collectPreparedXids() re-reads the transaction prepared list (TPL) before returning the XID list.

This is a somewhat expensive solution - but is sufficient for the time being as collectPreparedXids() is currently only called on recovery in the broker.

Fixed in r.2305 (trunk), r.2306 (1.0 branch)
Comment 2 Frantisek Reznicek 2008-09-11 03:34:59 EDT
RHTS test MRG_Messaging/qpid_xids_fails_bz458656 runs qpid.tests_0-10.dtx tests (which are passing) that proves that xid.recover response is now OK (->VERIFIED)
