Please note that the test case in the description uses an explicit primary key because I was told it makes bugs easier to investigate; but the failure is not only reproducible before the primary key, but also it seems far more obvious that the error on DELETE is already wrong – since there are no unique keys (defined by the user), there should be no duplicate key errors.

It was previously filed as MDEV-21137 and closed as a duplicate of MDEV-21138 without fixing MDEV-21138 and verifying that it covers both cases, and even without adding the alternative failure and test case to the bug report. Please don't do it with this one.
|
|
A slightly different test case, yet another completely different assertion failure. Again, don't discard it until it's been verified that the same fix fixes all of them, and add a test case for every variation of the failure.

Non-debug build doesn't crash, but it produces an unexpected error upon DELETE:
mysqltest: At line 14: query 'DELETE FROM t1' failed: 1062: Duplicate entry '2' for key 'PRIMARY'
|
|
|
Because this involves system versioning, I think that this belongs to midenok, who is the assignee of MDEV-21137 and MDEV-21138.
