Monty	57c3dd991b	MDEV-15106 Unexpected ER_WRONG_INSERT_INTO_SEQUENCE upon INSERT with multiple locks on sequences ... Fixed by removing the check of single lock in sequence insert and let MDL code handle deadlock detection	2018-05-03 17:49:39 +03:00
Michael Widenius	e27bfeca6a	Added test case for MDEV-15742 to prove that it works ... MDEV-15742 Assertion `table_share->tmp_table != NO_TMP_TABLE || m_lock_type == 1' failed in handler::ha_write_row	2018-04-06 12:31:13 +03:00
Monty	7d2e283562	Fix for MDEV-14831 ... MDEV-14831 CREATE OR REPLACE SEQUENCE under LOCK TABLE corrupts the sequence, causes ER_KEY_NOT_FOUND The problem was that sequence_insert didn't properly handle the case where there where there was a LOCK TABLE while creating the sequence. Fixed by opening the sequence table, for inserting the first record, in a new environment without any other open tables. Found also a bug in Locked_tables_list::reopen_tables() where the lock structure for the new tables was allocated in THD::mem_root, which causes crashes. This could cause problems with other create tables done under LOCK TABLES.	2018-04-02 12:42:48 +03:00
