MyISAM allows CHECK constraint violation in ALTER TABLE

    Details

      Description

      The test case added in
      MDEV-12389 ADD CHECK leaves an orphaned .par file
      fails in an unexpected way in 10.2.
      For InnoDB, the statement

      ALTER TABLE t1 ADD CHECK(b IN (0,1));
      

      fails as expected, because the column contains the values 0 and 10. However, MyISAM accepts the invalid constraint and only enforces it on subsequent DML operations.
