- Bug #18734396 INNODB IN-PLACE ALTER FAILURES BLOCK FUTURE ALTERS
-
- Analysis:
- When an InnoDB in-place ALTER fails, it leaves behind both a
- temporary filename like "#sql-ibtid" where tid represents the table ID of
- the table being altered) in its data dictionary. This makes future in-place
- ALTERs of the same table impossible because the temporary table is named
- only with the table ID.
-
- Solution:
- This patch is adding more uniqueness to the temporary file name. It
- creates a temporary tablename like
- "#sql-ibtid-inc" where
- tid = the table ID
- inc = static global number that is initialized to a random
- distributed 32-bit number using ut_time() and ut_crc32().It is then
- incremented atomically for each temporary file name assigned.
