Description

--source include/have_innodb.inc

CREATE TABLE t1 (a INT) ENGINE=InnoDB;

--error ER_CANT_DROP_FIELD_OR_KEY

ALTER TABLE t1 DROP FOREIGN KEY x, ALGORITHM=COPY;

# Cleanup

DROP TABLE t1;

10.5 8c0b9880

query 'ALTER TABLE t1 DROP FOREIGN KEY x, ALGORITHM=COPY' failed with wrong errno 1025: 'Error on rename of './test/t1' to './test/#sql2-10fa-4' (errno: 152 "Cannot delete a parent row")', instead of 1091...

Without ALGORITHM=COPY it fails with ER_CANT_DROP_FIELD_OR_KEY as expected.

There is an ancient upstream bug https://bugs.mysql.com/bug.php?id=14347 which seems related, but I'm not sure it's quite the same.
