      Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash · 74781d65
      ingo@mysql.com authored
      Version for 5.0.
      It fixes three problems:
      1. The cause of the bug was that we did not check the table version for
       the HANDLER ... READ commands. We did not notice when a table was
       replaced by a new one. This can happen during ALTER TABLE, REPAIR
       TABLE, and OPTIMIZE TABLE (there might be more cases). I call the fix
       for this problem "the primary bug fix".
      2. mysql_ha_flush() was not always called with a locked LOCK_open.
       Though the function comment clearly said it must.
       I changed the code so that the locking is done when required. I call
       the fix for this problem "the secondary fix".
      3. In 5.0 (not in 4.1 or 4.0) DROP TABLE had a possible deadlock flaw in
       concur with FLUSH TABLES WITH READ LOCK. I call the fix for this
       problem "the 5.0 addendum fix".
