    Message Recovery - completing XA

    Adrian Brock Master

      Hi,

      I'm still not ready to commit, but I'm getting closer :-).
      By now the patch seems to work for me.

      What's on my ToDo list?

      - Testing:
      - Topics
      - All my stuff should only take effect if it is explicitly turned on
      - Compatibility of client jars (I added two new methods for the QueueBrowser)
      - General Tests in our testing environment
      - JBoss testsuite
      - Review Code
      - Add comments
      - Port it to JBoss-3.2.4 final / CVS checkout

      Since I'm using MySQL <4.1, I can't use subqueries. Therefore,
      I had to modify the jdbc3/PersistenceManager to work without
      subqueries (can be configured).

      I'm not really sure, but I believe that I don't have to worry about timings, transactions and acknowledgement (points 2 and 4 in the first post in this thread), since the only thing I did is to modify the "TreeMap messages", such that it holds only the first N MessageReferences in the queue. If more data is needed, it is (re)constructed from the PersistenceManager. That means, that my modifications don't affect transactions or acknowledgement, am I right?

      And no, in the current version I don't unload messages. This might be a reasonable improvement for future versions...

      My sourceforge id is 735867.

      I assume, I should commit to the JBoss_3_2 branch. How about the head/JBoss_4_0? I might have some more questions when I'm getting closer to commit :-).
