ER_KEY_NOT_FOUND upon concurrent CHANGE column to autoinc and DML

Details

    Description

      Notes:

      • A fix for MDEV-31043 is already in the branch. Besides, this time the failure affects transactional engines as well, reproducible with at least InnoDB, MyISAM, Aria, HEAP.
      • The test case is non-deterministic, run with --repeat=N. It fails for me on almost every attempt, but it can vary on different machines and builds.
      • The second table (t2) seems to be important somehow, at least I couldn't replace its operation with just a sleep.

      --source include/have_sequence.inc
      		 
       
      		 
      CREATE TABLE t1 (b int);
      		 
      INSERT INTO t1 VALUES (0),(0);
      		 
       
      		 
      CREATE TABLE t2 (a int);
      		 
      INSERT INTO t2 (a) select seq from seq_1_to_128;
      		 
       
      		 
      --connect (con1,localhost,root,,)
      		 
      --send
      		 
        ALTER TABLE t1 MODIFY b SERIAL;
      		 
       
      		 
      --connection default
      		 
      DELETE FROM t2 ORDER BY a LIMIT 1;
      		 
      DELETE FROM t1 ORDER BY b LIMIT 2;
      		 
       
      		 
      --connection con1
      		 
      --reap
      		 
       
      		 
      # Cleanup
      		 
      DROP TABLE t1, t2;
