revno: 2617.31.26
committer: Alexander Nozdrin <alik@sun.com>
branch nick: 6.0-rt-bug43138.3

message:
  Fix for Bug#43138: DROP DATABASE failure does not clean up message list.
  
  The problem was that the high-level function mysql_rm_db() invoked
  low-level mysql_rm_table_part2(), which reported low-level error
  (Unknown table) if SE refused to delete a table. Also when
  mysql_rm_table_part2() reported an error, it didn't add corresponding
  warning into the list (because it is used from other places where such
  behaviour is required).
  
  The fix is to
    1. Remove no_warnings_for_error usage from sql_table.cc
    2. Improve internal error handler support in THD, so that
       a stack of error handlers is allowed.
    3. Create an internal error handler (Drop_table_error_handler)
       to silence useless warnings.
    4. Use the handler in DROP DATABASE and DROP TABLE statements.
