INSERT BUFFER MERGE Problem: When the record is merged from the change buffer to the actual page, in a particular condition, it is assumed that the deleted rec will be re-used by the inserted rec. With this assumption the lock is restored on the pointer to the deleted rec itself, thinking that it is pointing to the newly inserted rec. Solution: Just before restoring the lock, update the rec pointer to point to the newly inserted record. An assert has been added to verify this. This assert will fail without the fix and will pass with the fix. rb#2449 in review by Marko and Jimmy |
