      BUG#19145: mysqld crashes if you set the default value of an enum field to NULL · dd68976a
      unknown authored
      Now test for NULLness the pointers returned from objects created from the
      default value. Pushing patch on behalf of cmiller.
      
      
      mysql-test/r/null.result:
        Add test case
      mysql-test/t/null.test:
        Add test case
      sql/sql_table.cc:
        No longer blindly dereference pointer of the string representation of the
        values, where "NULL" is NUL. Raise INVALID DEFAULT error messages where
        appropriate.
        
        Note that the -O1 optimization flag made debugging this extremely tricky, with
        misleading results, and that removing it from the Makefile during debugging can
        be invaluable.

      BUG#18492: mysqld reports ER_ILLEGAL_REFERENCE in --ps-protocol · 3a0d0b4c
      unknown authored
      In the code that converts IN predicates to EXISTS predicates it is changing
      the select list elements to constant 1. Example :
      SELECT ... FROM ...  WHERE a IN (SELECT c FROM ...)
      is transformed to :
      SELECT ... FROM ... WHERE EXISTS (SELECT 1 FROM ...  HAVING a = c)
      However there can be no FROM clause in the IN subquery and it may not be
      a simple select : SELECT ... FROM ... WHERE a IN (SELECT f(..) AS
      c UNION SELECT ...) This query is transformed to : SELECT ... FROM ...
      WHERE EXISTS (SELECT 1 FROM (SELECT f(..) AS c UNION SELECT ...)
      x HAVING a = c) In the above query c in the HAVING clause is made to be
      an Item_null_helper (a subclass of Item_ref) pointing to the real
      Item_field (which is not referenced anywhere else in the query anymore).
      This is done because Item_ref_null_helper collects information whether
      there are NULL values in the result.  This is OK for directly executed
      statements, because the Item_field pointed by the Item_null_helper is
      already fixed when the transformation is done.  But when executed as
      a prepared statement all the Item instances are "un-fixed" before the
      recompilation of the prepared statement. So when the Item_null_helper
      gets fixed it discovers that the Item_field it points to is not fixed
      and issues an error.  The remedy is to keep the original select list
      references when there are no tables in the FROM clause. So the above
      becomes : SELECT ... FROM ...  WHERE EXISTS (SELECT c FROM (SELECT f(..)
      AS c UNION SELECT ...) x HAVING a = c) In this way c is referenced
      directly in the select list as well as by reference in the HAVING
      clause. So it gets correctly fixed even with prepared statements.  And
      since the Item_null_helper subclass of Item_ref_null_helper is not used
      anywhere else it's taken out.
