If lock type is LOCK_GAP or LOCK_ORDINARY, and the transaction holds implicit lock for the record, then explicit gap-lock will not be set for the record, as lock_rec_convert_impl_to_expl() returns true and lock_rec_convert_impl_to_expl() bypasses lock_rec_lock() call. The fix converts explicit lock to implicit one if requested lock type is not LOCK_REC_NOT_GAP. innodb_information_schema test result is also changed as after the fix the following statements execution: SET autocommit=0; INSERT INTO t1 VALUES (5,10); SELECT * FROM t1 FOR UPDATE; leads to additional gap lock requests. |
