      * Bug #20792: Incorrect results from aggregate subquery · 6b75e24b
      unknown authored
      When processing aggregate functions all tables values are reset
      to NULLs at the end of each group. 
      When doing that if there are no rows found for a group
      the const tables must not be reset as they are not recalculated 
      by do_select()/sub_select() for each group.

         - test suite for the bug. This is dependent on InnoDB despite
           the fact that the bug and the fix are not InnoDB specific.
           This is because of the table flag HA_NOT_EXACT_COUNT.
           When this flag is off (as in MyISAM) both t2 and t3 become of
           join type 'system' as they are estimated to have 1 record and
           and this statistics can be trusted (according to the absence of
           HA_NOT_EXACT_COUNT).

      BUG#21206: memory corruption when too many cursors are opened at once · 35945019
      unknown authored
      Too many cursors (more than 1024) could lead to memory corruption.
      This affects both, stored routines and C API cursors, and the
      threshold is per-server, not per-connection.  Similarly, the
      corruption could happen when the server was under heavy load
      (executing more than 1024 simultaneous complex queries), and this is
      the reason why this bug is fixed in 4.1, which doesn't support
      cursors.
      
      The corruption was caused by a bug in the temporary tables code, when
      an attempt to create a table could lead to a write beyond allocated
      space.  Note, that only internal tables were affected (the tables
      created internally by the server to resolve the query), not tables
      created with CREATE TEMPORARY TABLE.  Another pre-condition for the
      bug is TRUE value of --temp-pool startup option, which, however, is a
      default.
      
      The cause of a bug was that random memory was overwritten in
      bitmap_set_next() due to out-of-bound memory access.
      
      
      mysys/my_bitmap.c:
        Local 'bitmap_size' is measured in bytes, no need to multiply it by 8.
      sql/sql_select.cc:
        Clear the temp_pool_slot bit only if we have set it previously.

      Bug #21019: First result of SELECT COUNT(*) different than consecutive runs · 5ca1ee5e
      unknown authored
       When optimizing conditions like 'a = <some_val> OR a IS NULL' so that they're
       united into a single condition on the key and checked together the server must 
       check which value is the NULL value in a correct way : not only using ->is_null 
       but also check if the expression doesn't depend on any tables referenced in the 
       current statement. 
       This additional check must be performed because that optimization takes place 
       before the actual execution of the statement, so if the field was initialized 
       to NULL from a previous statement the optimization would be applied incorrectly.

           Note that ALTER TABLE is important here : it happens to
           leave the Field instance for t1.b set to NULL, witch is vital for

      Fix for BUG#20954: avg(keyval) retuns 0.38 but max(keyval) returns an empty set · 585b5bbc
      unknown authored
      The problem was in that opt_sum_query() replaced MIN/MAX functions
      with the corresponding constant found in a key, but due to imprecise
      representation of float numbers, when evaluating the where clause,
      this comparison failed.
      
      When MIN/MAX optimization detects that all tables can be removed,
      also remove all conjuncts in a where clause that refer to these
      tables. As a result of this fix, these conditions are not evaluated
      twice, and in the case of float number comparisons we do not discard
      result rows due to imprecise float representation.
      
      As a side-effect this fix also corrects an unnoticed problem in
      bug 12882.
      
      
      mysql-test/r/func_group.result:
        BUG#20954 - test result adjustment.
        Adjusted the test result of bug 12882 which was not preperly fixed.
        The current patch corrects the problem that was fully corrected by the
        patch for 12882.
        
        The problem was that opt_sum_query() indicated that the optimizer may
        remove all tables because all MIN/MAX/COUNT functions are constants,
        but this lead to an empty result instead of NULL because the WHERE
        clause was still evaluated.
        
        The current fix removes all conjuncts in the where clause that
        reference the removed tables, and thus corrects the problem.
      mysql-test/r/select.result:
        BUG#20954 - added test
      mysql-test/r/subselect.result:
        BUG#20954 - test result adjustment.
        
        The fix removes those conditions in a where clause that refer to
        tables optimized away by MIN/MAX optimization (opt_sum_query()).
      mysql-test/t/select.test:
        BUG#20954 - added test
