    Details

      Description

      Note: The test case is similar to MDEV-14844, only here with system_time partitioning we are getting a crash, not the assertion failure.

      CREATE OR REPLACE TABLE t1 (pk int) ENGINE=InnoDB WITH SYSTEM VERSIONING PARTITION BY system_time INTERVAL 4 HOUR (PARTITION p1 HISTORY, PARTITION pn CURRENT);
      LOCK TABLE t1 WRITE;
      SET system_versioning_alter_history=KEEP;
      --error ER_SAME_NAME_PARTITION
      ALTER TABLE t1 ADD PARTITION (PARTITION p1 HISTORY);
      SELECT * FROM t1;
       
      # Cleanup
      DROP TABLE t1;
