Another script that repeats the problem:

create or replace table t1 (a bit(15), va bit(10) generated always as (a),pk int, primary key (pk), unique key (va)) engine=innodb;

insert ignore into t1 values (0x400,0,1);

replace into t1 (pk) values (1);

The maximum possible value for the generated column va is 0x3FF.
This scripts inserts 0x400 to the regular column a, so 0x400 gets truncated to 0x3FF when being copied to va.

The same problem is repeatable with a simplified script:

create or replace table t1 (a bit(15), va bit(10) generated always as (a),pk int, primary key (pk), unique key (va)) engine=innodb;

insert ignore into t1 (a,pk) values (0x400,1);

replace into t1 (pk) values (1);

I just checked this in a 10.5-based branch:

create table t1 (a bit(15), va bit(10) generated always as (a),pk int, primary key (pk), unique key (va)) engine=innodb;

insert ignore into t1 values (0x400,0,1);

Warnings:

Warning	1906	The value specified for generated column 'va' in table 't1' has been ignored

Warning	1264	Out of range value for column 'va' at row 1

replace into t1 (pk) values (1);

An assertion fails during the REPLACE, similar to the Description. The index contents are as follows:
(pk,DB_TRX_ID,DB_ROLL_PTR,a)=delete-marked(1,32,…,0x400) (delete-marked by the current transaction)
(va,pk)=(0x3ff,1)

We fail to find the secondary index record, because we are searching for an index entry of (va,pk)=(NULL,1) instead of (0x3ff,1).

The problem seems to be that INSERT IGNORE is replacing the out-of-range bitmap value 0x400 with 0x3ff, while REPLACE is substituting NULL.

I think that INSERT IGNORE must always compute indexed virtual column values in a way that is compatible with everything else. If virtual column values are materialized in an index or table, they must be evaluated consistently in all cases.

Perhaps the IGNORE should be ignored altogether when indexed virtual columns exist, and the statement should return an error in this case?

I think it should also fail with single DELETE IGNORE

A fix for ignoring a truncation is quite fresh – it was just a year ago, and the truncation was failing before in a variety of ways.

So i think that we can just forbid REPLACEs to forcibly succeed with truncation (and other ignored by IGNORE sql modes).

marko I think we can try not to ignore IGNOREs altogether for the sake of keeping legacy working. It is pretty possible that people use indexes with and without IGNOREs, but for example do not use REPLACEs. Or if they use Aria/Myisam

The problem in this (~~MDEV-20618~~) case is that a virtual column computation failure was erroneously treated as NULL inside innodb – some error handling was missing

I think that INSERT IGNORE should discard rows where virtual column values cannot be evaluated. It would be analogous to INSERT IGNORE discarding rows that would violate UNIQUE KEY or PRIMARY KEY.

I think that we must always try to propagate the errors up in the call stack. The suggested fix is not doing that in all code paths.

Unfortunately, current behaviour is documented: https://mariadb.com/kb/en/insert-ignore/, so changing it will very much likely break existing workflows. It can't be done for 10.2-10.5, but we can think of changing it in 10.6+.

As for the error propagation – I completely 100% agree with both hands. But the amount of refactoring would be just amazing. Maybe we can think of it for 10.6, again, but it seems we've already run out of effort for the next release. Though we can still raise that topic up on email.

The test case which I used for verification is below, also for a record. It seems to be deterministic on affected builds, I just did not prettify it since the problem has already been fixed.
