Monty	b050df4fd3	MDEV-14943 Alter table ORDER BY bug ... Problem was that if copy_data_between_tables() didn't do proper clean up in case of failures: - copy object was not properly freed - end_bulk_insert() was not called - mysql_trans_prepare_alter_copy_data() set THD->transaction.on to false which was not properly restored The last part caused a crash in Aria as Aria depends on that THD is correct. Other things: - Reset info->switched_transactional after usage (safety) - Reset bulk_insert_single_undo (safety)	2018-05-15 13:12:35 +03:00

Michael Widenius	3d67c68ad1	Fixed MDEV-4970: Wrong result with Aria table populated with disabled keys ... Problem was that ALTER TABLE DISABLE KEYS incremented create_trid for the table, which made the new index entries invisible until the global trid catched up. Fixed by only updating create_trid if we are rewriting all rows and indexes. mysql-test/suite/maria/alter.result: Added test case mysql-test/suite/maria/alter.test: Added test case storage/maria/ha_maria.cc: Only updating create_trid if we are doing a full repair (and thus rewriting all rows and indexes). storage/maria/trnman.c: More DBUG_PRINT	2014-01-25 15:41:08 +02:00
