Description
Summary
In binlog_format=MIXED, the trigger-called stored-procedure reproduction
also leaves the replica with different committed rows when the only FK-bearing
routine side-effect table is the second routine write instead of the first.
This variant changes FK placement while keeping the trigger, procedure,
AUTO_INCREMENT, ROLLBACK TO SAVEPOINT, and ordinary witness INSERT
shape.
Environment
- Product: MariaDB Server primary/replica replication
- Replication mode: file/position
- binlog_format: MIXED
- Observed affected versions: MariaDB 10.6, 12.2
- Clean controls: MariaDB 10.6/12.2 with ROW; MySQL 5.6/5.7/8.0
with MIXED - Storage engine: InnoDB
Steps To Reproduce
1. Start a MariaDB primary/replica pair with binlog_format=MIXED.
2. Run the SQL in the Minimal Reproduction SQL section on the primary.
3. Wait for the replica to catch up.
4. Run this query on both primary and replica:
SELECT seq, src_id, frame_v, note |
FROM acl_repl_ai_proc_min2_frame |
ORDER BY seq; |
Minimal Reproduction SQL
-- MariaDB primary/replica repro. Configure binlog_format=MIXED.
|
-- Variant: the FK is on the second routine side-effect table.

Expected Result
The primary and replica should return the same committed rows.
Expected rows:
1, 1, 7010, proc-seed
|
2, 2, 7020, proc-prefix
|
4, 4, 7040, proc-witness
|
Actual Result
Primary:
1, 1, 7010, proc-seed
|
2, 2, 7020, proc-prefix
|
4, 4, 7040, proc-witness
|
Replica:
1, 1, 7010, proc-seed
|
2, 2, 7020, proc-prefix
|
3, 4, 7040, proc-witness
|
Separate Verification Request
Please verify this FK-placement form separately. The only FK-bearing routine side-effect table is the second routine write, while the first routine side-effect table has no FK.
