- InnoDB should avoid bulk insert operation when table has active DDL. Because bulk insert writes only one undo log as TRX_UNDO_EMPTY and logging of concurrent DML happens at commit time uses undo log record to parse and get the value and operation. - Removed ROW_T_EMPTY, ROW_OP_EMPTY and their associated functions and also the test case which tries to log the ROW_OP_EMPTY when table has active DDL.
