Description
MariaDB [xxx]> LOCK TABLE m WRITE; Query OK, 0 rows affected (0.00 sec) MariaDB [xxx]> START TRANSACTION; Query OK, 0 rows affected (0.00 sec) MariaDB [xxx]> LOCK TABLE t WRITE; Query OK, 0 rows affected (0.00 sec) MariaDB [xxx]> START TRANSACTION; Query OK, 0 rows affected, 1 warning (0.00 sec) Warning (Code 1105): external_lock: unexpected command 59
The table `m` is MyISAM but, as far as I can tell, no warning occurs with other storage engines. The table `t` is CONNECT, which seems to be the only engine that issues a warning.
I report this behavior because you probably want to be aware about inconsistencies between engines. But, to be honest, I prefer CONNECT's behavior: when a trx starts, table locks are lost, and this is something I want to know. I hope that a more informative warning will be issued, no matter which engine I am using.

Hi Federico,
Thanks. Inconsistency is always suspicious, e.g. as soon as I started verifying it, I got this:
MDEV-6994.And of course if the warning happens to be intentional, it should come with a better message.
