      fix for bug #19690: ORDER BY eliminates rows from the result · 03f5218e
      unknown authored
      Depending on the queries we use different data processing methods
      and can lose some data in case of double (and decimal in 4.1) fields.
      
      The fix consists of two parts:
      1. double comparison changed, now double a is equal to double b 
      if (a-b) is less than 5*0.1^(1 + max(a->decimals, b->decimals)). 
      For example, if a->decimals==1, b->decimals==2, a==b if (a-b)<0.005
      2. if we use a temporary table, store double values there as is 
      to avoid any data conversion (rounding).
      
      
      mysql-test/r/type_float.result:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - test result
      mysql-test/t/type_float.test:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - test case
      sql/field.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - use not_fixed flag instead of dec to check bounds.
      sql/field.h:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - Field_Double::not_fixed flag introduced, which is set if dec == NOT_FIXED_DEC
            and is used in the ::store() to check bounds. 
          - new constructor introduced (with not_fixed_arg parameter).
      sql/init.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - fill log_01[] array with 0.1 powers.
      sql/item_cmpfunc.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - compare_real_fixed() and compare_e_real_fixed() introduced,
            they consider double a == double b if a-b is less than 'precision',
            'precision' is set to 5*0.1^(1 + max(a->decimals, b->decimals)), 
            for example, if a->decimals==1, b->decimals==2, 'precision' is 0.005
          - use the above functions if both arguments are fixed.
      sql/item_cmpfunc.h:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - Arg_comparator::presision introduced.
          - Arg_comparator::compare_real_fixed(), Arg_comparator::compare_e_real_fixed() introduced.
      sql/mysql_priv.h:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - log_01 array of 0.1 powers added.
      sql/mysqld.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - log_01 array of 0.1 powers added.
      sql/sql_select.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - if we create double field in a temporary table, set not_fixed flag
            (use proper constructor) to avoid data conversion 
            in the Field_double::store(). Otherwise we can lose some data.
