Server crashes, heap-buffer-overflow, table corruption, assertion failures upon DML on Aria table with SPATIAL

    XMLWordPrintable

    Details

      Description

      It looks like all bad things start from the UPDATE, which really should fail with ER_CANT_CREATE_GEOMETRY_OBJECT, but it doesn't.

      CREATE TABLE t (c POINT NOT NULL, SPATIAL(c)) ENGINE=Aria;
      REPLACE INTO t (c) VALUES (POINT(0,0));
      UPDATE t SET c = '';
       
      # Cleanup
      DROP TABLE t;

      mysqltest: At line 3: query 'UPDATE t SET c = ''' failed: 1034: Index for table 't' is corrupt; try to repair it
      

      All the above is from the same test case. Here is a slightly different one, with a slightly different stack trace:

      CREATE TABLE t (c POINT NOT NULL, d DATE, INDEX(d), SPATIAL(c)) ENGINE=Aria;
      INSERT INTO t (c) VALUES (POINT(0,0));
      UPDATE IGNORE t SET c = NULL;
      DELETE FROM t LIMIT 4;
       
      # Cleanup
      DROP TABLE t;
