      Fixed bug#17366: Unchecked Item_int results in server crash · 8ba5a687
      unknown authored
      When there is conjunction of conds, the substitute_for_best_equal_field()
      will call the eliminate_item_equal() function in loop to build final
      expression. But if eliminate_item_equal() finds that some cond will always
      evaluate to 0, then that cond will be substituted by Item_int with value ==
      0. In this case on the next iteration eliminate_item_equal() will get that 
      Item_int and treat it as Item_cond. This is leads to memory corruption and
      server crash on cleanup phase.
      
      To the eliminate_item_equal() function was added DBUG_ASSERT for checking
      that all items treaten as Item_cond are really Item_cond.
      The substitute_for_best_equal_field() now checks that if
      eliminate_item_equal() returns Item_int and it's value is 0 then this 
      value is returned as the result of whole conjunction.

      BUG#15101 SYSDATE() disregards SET TIMESTAMP. · 8f543b5e
      unknown authored
         After the ChangeSet 1.1892.20.1 2005/08/24 (Bug #12562) SYSDATE() is not an alias
         of NOW() and is unsafe for replication.
         `SYSDATE()' backward compatible aliasing clashes with the idea #12562 
         fix. To make it safe-replicatable we have to either use RBR or to restore
         the pre-5.0 style.
         --sysdate-is-now command line flag was introduced to provide backward compatibility.

      Bug#14980 - COUNT(*) incorrect on MyISAM table with certain INDEX · fbe17c2a
      unknown authored
      For "count(*) while index_column = value" an index read
      is done. It consists of an index scan and retrieval of
      each key.
      
      For efficiency reasons the index scan stores the key in
      the special buffer 'lastkey2' once only. At the first 
      iteration it notes this fact with the flag 
      HA_STATE_RNEXT_SAME in 'info->update'.
      
      For efficiency reasons, the key retrieval for blobs
      does not allocate a new buffer, but uses 'lastkey2'...
      
      Now I clear the HA_STATE_RNEXT_SAME flag whenever the 
      buffer has been polluted. In this case, the index scan
      copies the key value again (and sets the flag again).
      
      
      include/my_base.h:

      Fixed bug#13575: SP funcs in select with distinct/group and order by can · 50c8c206
      unknown authored
      produce wrong data
      
      By default Item_sp_func::val_str() returns string from it's result_field 
      internal buffer. When grouping is present Item_copy_string is used to 
      store SP function result, but it doesn't additionally buffer the result.
      When the next record is read, internal buffer is overwritten, due to
      this Item_copy_string::val_str() will have wrong data. Thus producing
      weird query result.
      
      The Item_func_sp::val_str() now makes a copy of returned value to prevent
      occasional corruption.
