MDEV-13437 InnoDB fails to return error for XA COMMIT or XA ROLLBACK in read-only mode Assertions failed due to incorrect handling of the --tc-heuristic-recover option when InnoDB is in read-only mode either due to innodb_read_only=1 or innodb_force_recovery>3. InnoDB failed to refuse a XA COMMIT or XA ROLLBACK operation, and there were errors in the error handling in the upper layer. This was fixed by making InnoDB XA operations respect the high_level_read_only flag. The InnoDB part of the fix and parts of the test main.tc_heuristic_recover were provided by Marko Mäkelä. LOCK_log mutex lock/unlock had to be added to fix MDEV-13438. The measure is confirmed by mysql sources as well. For testing of the conflicting option combination, mysql-test-run is made to export a new $MYSQLD_LAST_CMD. It holds the very last value generated by mtr.mysqld_start(). Even though the options have been also always stored in $mysqld->{'started_opts'} there were no access to them beyond the automatic server restart by mtr through the expect file interface. Effectively therefore $MYSQLD_LAST_CMD represents a more general interface to $mysqld->{'started_opts'} which can be used in wider scopes including server launch with incompatible options. Notice another existing method to restart the server with incompatible options relying on $MYSQLD_CMD is is aware of $mysqld->{'started_opts'} (the actual options that the server is launched by mtr). In order to use this method they would have to be provided manually. NOTE: When merging to 10.2, the file search_pattern_in_file++.inc should be replaced with the pre-existing search_pattern_in_file.inc.
