fixed in 4.1, the test case for this code is also there).

  Handling of COM_CREATE_DB, COM_DROP_DB:
  We should call send_error() if mysql_create_db or mysql_drop_db
  return error (like we do it for SQL versions of these commands).

when one connection had done FLUSH TABLES WITH READ LOCK, some updates, and then COMMIT,
it was accepted but my_error() was called and so, while client got no error, error was logged in binlog.
We now don't call my_error() in this case; we assume the connection know what it does.
This problem was specific to 4.0.21. The change is needed to make replication work with existing versions of innobackup.


sql/lock.cc:
  If a connection has done FLUSH TABLES WITH READ LOCK and now is doing COMMIT, don't give error
  (applies only if it's the same connection; others' COMMITs are still blocked).

  Fix bug #5960: if one updated a column so that its size changed, or updated it to an externally stored (TEXT or BLOB) value, then ANOTHER externally stored column would show up as 512 bytes of good data + 20 bytes of garbage in a consistent read that fetched the old version of the row
