      In fix for BUG#15872, a condition of type "t.key NOT IN (c1, .... cN)"
      where N>1000, was incorrectly converted to
        (-inf < X < c_min) OR (c_max < X)
      Now this conversion is removed, we dont produce any range lists for such
      conditions.

      Bug #21159: Optimizer: wrong result after AND with different data types · 3915c3d9
      unknown authored
      Disable const propagation for Item_hex_string.
      This must be done because Item_hex_string->val_int() is not
      the same as (Item_hex_string->val_str() in BINARY column)->val_int().
      We cannot simply disable the replacement in a particular context (
      e.g. <bin_col> = <int_col> AND <bin_col> = <hex_string>) since
      Items don't know the context they are in and there are functions like 
      IF (<hex_string>, 'yes', 'no').
      Note that this will disable some valid cases as well 
      (e.g. : <bin_col> = <hex_string> AND <bin_col2> = <bin_col>) but 
      there's no way to distinguish the valid cases without having the
      Item's parent say something like : Item->set_context(Item::STRING_RESULT)
      and have all the Items that contain other Items do that consistently.

      Bug #21302: Result not properly sorted when using an ORDER BY on a second · 06a302ef
      unknown authored
                   table in a join
       The optimizer removes redundant columns in ORDER BY. It is considering 
      redundant every reference to const table column, e.g b in :
      create table t1 (a int, b int, primary key(a)); 
      select 1 from t1 order by b where a = 1
      
      But it must not remove references to const table columns if the 
      const table is an outer table because there still can be 2 values :
      the const value and NULL. e.g.:
      create table t1 (a int, b int, primary key(a));
      select t2.b c from t1 left join t1 t2 on (t1.a = t2.a and t2.a = 5) 
        order by c;

      BUG#20060 - mysqld option "--flush " doesn't work for update statement · a2a5f2b5
      unknown authored
      Problem described in this bug report affects MyISAM tables only.
      
      Running mysqld --flush instructs mysqld to sync all changes to disk
      after each SQL statement. It worked well for INSERT and DELETE
      statements, but it did sync for UPDATE only in case if there was
      index change (change of colum that has an index). If no updated column
      has an index, data wasn't synced to disk.
      
      This fix makes UPDATE statement to sync data to disk even if there is
      no index change (that is only data change) and mysqld is run with
      --flush option.
      
      
      myisam/mi_update.c:
        Every myisam function that updates myisam table must end with
        call to _mi_writeinfo(). If operation (second param of
        _mi_writeinfo()) is not 0 it sets share->changed to 1, that is
        flags that data has changed. If operation is 0, this function
        equals to no-op in this case.
        
        mi_update() must always pass !0 value as operation, since even if
        there is no index change there could be data change.
