      BUG#26624: high mem usage (crash) in range optimizer · 9639eb3d
      unknown authored
      - Added PARAM::alloced_sel_args where we count the # of SEL_ARGs
        created by SEL_ARG tree cloning operations.
      - Made the range analyzer to shortcut and not do any more cloning 
        if we've already created MAX_SEL_ARGS SEL_ARG objects in cloning.
      - Added comments about space complexity of SEL_ARG-graph 
        representation.

      - Define Sql_alloc::operator new() as thow() so that C++ compiler
        handles NULL return values
      (there is no testcase as there is no portable way to set limit on the 
      amount of memory that a process can allocate)

      Bug #27300: · c8f1cf4c
      unknown authored
        Geometry fields have a result type string and a 
        special subclass to cater for the differences
        between them and the base class (just like 
        DATE/TIME).
        When creating temporary tables for results of 
        functions that return results of type GEOMETRY
        we must construct fields of the derived class 
        instead of the base class.
        Fixed by creating a GEOMETRY field (Field_geom) 
        instead of a generic BLOB (Field_blob) in temp 
        tables for the results of GIS functions that 
        have GEOMETRY return type (Item_geometry_func).

      Bug #27164: not reseting the data pointer · 3335f68d

       to 0 causes wrong (large) length to be read
       from the row in _mi_calc_blob_length() when 
       storing NULL values in (e.g) POINT columns.
       This large length is then used to allocate
       a block of memory that (on some OSes) causes
       trouble.
       Fixed by calling the base class's 
       Field_blob::reset() from Field_geom::reset()
       that is called when storing a NULL value into
       the column.

        count_field_types underestimated the number of elements in
        in the array param->items_to_copy.
        
        Currently it's not guaranteed that after JOIN::prepare() the 
        used_tables attribute is calculated for all items. For example
        for the expression SUM(outer_ref)+1 used_tables() must return
        OUTER_REF_TABLE_BIT. Yet by the moment when the used_tables
        attribute is calculated in JOIN::prepare SUM(outer_ref) has
        not been substituted for Item_aggregate_ref yet.
        By this reason additional calls of the method update_used_tables
        are needed for some items passed as parameters to the function
        create_tmp_table.

      the error is thrown because only a super-user can set other users as a definers.

       in index search MySQL was not explicitly

       happens to enable warnings (e.g. INSERT ..
       SELECT) the warnings resulting from converting 
       the data the key is compared to are 
       reported to the client.
       Fixed by suppressing warnings when converting

      Bug #24791: Union with AVG-groups generates wrong results · aa323361
      unknown authored
      The problem in this bug is when we create temporary tables. When
      temporary tables are created for unions, there is some 
      inferrence being carried out regarding the type of the column.
      Whenever this column type is inferred to be REAL (i.e. FLOAT or
      DOUBLE), MySQL will always try to maintain exact precision, and
      if that is not possible (there are hardware limits, since FLOAT
      and DOUBLE are stored as approximate values) will switch to
      using approximate values. The problem here is that at this point
      the information about number of significant digits is not 
      available. Furthermore, the number of significant digits should
      be increased for the AVG function, however, this was not properly 
      handled. There are 4 parts to the problem:
      
      #1: DOUBLE and FLOAT fields don't display their proper display 
      lengths in max_display_length(). This is hard-coded as 53 for 
      DOUBLE and 24 for FLOAT. Now changed to instead return the 
      field_length.
      
      #2: Type holders for temporary tables do not preserve the 
      max_length of the Item's from which they are created, and is 
      instead reverted to the 53 and 24 from above. This causes 
      *all* fields to get non-fixed significant digits.
      
      #3: AVG function does not update max_length (display length)
      when updating number of decimals.
      
      #4: The function that switches to non-fixed number of 
      significant digits should use DBL_DIG + 2 or FLT_DIG + 2 as 
      cut-off values (Since fixed precision does not use the 'e' 
      notation)
      
      Of these points, #1 is the controversial one, but this 
      change is preferred and has been cleared with Monty. The 
      function causes quite a few unit tests to blow up and they had
      to b changed, but each one is annotated and motivated. We 
      frequently see the magical 53 and 24 give way to more relevant
      numbers.

        changed test result
        
        With the changes made for FLOAT and DOUBLE, the original display
        lengths are now preserved.

        bug#24791
        
        changed test result
        
        delta 1: field was originally declared as DOUBLE with no display
        length, so the hardware maximum is chosen rather than 53.
        
        delta 2: fields exceed the maximum precision and thus switch to
        non-fixed significant digits
        
        delta 3: Same as above, number of decmals and significant digits
        was not specified when t3 was created.

        Test case
      sql/field.h:
        bug#24791
        
        The method max_display_length is reimplemented as
        
        uint32 max_display_length() { return field_length; }
        
        in Field_double and Field_float. Since all subclasses of 
        Field_real now have the same implementation of this method, the
        implementation has been moved up the hierarchy to Field_real.
      sql/item.cc:
        bug#24791
        
        We switch to a non-fixed number of significant digits
        (by setting decimals=NOT_FIXED_DECIMAL) if the calculated 
        display length is greater than the display length of a value 
        with the maximum precision. These values differ for double and 
        float, obviously.
      sql/item_sum.cc:
        bug#24791
        
        We must increase the display length accordinly whenever we 
        change number of decimal places.

      bug #16546 (DATETIME+0 not always coerced the same way) · 2b983572
      unknown authored
        fix for cast( AS DATETIME)+0 in 5.0 and above versions.
        val_real now works using val_decimal for DATETIME Items
        Superfluous val_real() methods deleted
      
      
      sql/item_timefunc.h:
        val_real() for datetime functions implemented
            as { return val_real_from_decimal(); }
            It's not a fastest possible way, but code is simple and less
            error-prone, what i belive is more important here as this part
            works unfrequently.
