      Fixed bug #16674. · 69977fa5
      unknown authored
      The length of the prefix of the pattern string in the LIKE predicate that 
      determined the index range to be scanned was calculated incorrectly for
      multi-byte character sets. 
      As a result of this in 4. 1 the the scanned range was wider then necessary
      if the prefix contained not only one-byte characters.  
      In 5.0 additionally it caused missing some rows from the result set.

      * Bug #9676: INSERT INTO x SELECT .. FROM x LIMIT 1; slows down with big · 124cb126
      unknown authored
                    tables
      Currently in INSERT ... SELECT ... LIMIT ... the compiler uses a 
      temporary table to store the results of SELECT ... LIMIT .. and then
      uses that table as a source for INSERT. The problem is that in some cases
      it actually skips the LIMIT clause in doing that and materializes the 
      whole SELECT result set regardless of the LIMIT.
      This fix is limiting the process of filling up the temp table with only 
      that much rows that will be actually used by propagating the LIMIT value.

      BUG#18036 - update of table joined to self reports table as crashed · 46cdd39e
      unknown authored
      Certain updates of table joined to self results in unexpected
      behavior.
      
      The problem was that record cache was mistakenly enabled for
      self-joined table updates. Normally record cache must be disabled
      for such updates.
      
      Fixed wrong condition in code that determines whether to use
      record cache for self-joined table updates.
      
      Only MyISAM tables were affected.

      Fixed bug#16377: result of DATE/TIME functions were compared as strings which · 47311e8e
      unknown authored
      can lead to a wrong result.
      
      All date/time functions has the STRING result type thus their results are
      compared as strings. The string date representation allows a user to skip 
      some of leading zeros. This can lead to wrong comparison result if a date/time 
      function result is compared to such a string constant.
      
      The idea behind this bug fix is to compare results of date/time functions
      and data/time constants as ints, because that date/time representation is 
      more exact. To achieve this the agg_cmp_type() is changed to take in the
      account that a date/time field or an date/time item should be compared 
      as ints.
      
      This bug fix is partially back ported from 5.0.
      
      The agg_cmp_type() function now accepts THD as one of parameters. 
      In addition, it now checks if a date/time field/function is present in the
      list. If so, it tries to coerce all constants to INT to make date/time
      comparison return correct result. The field for the constant coercion is
      taken from the Item_field or constructed from the Item_func. In latter case
      the constructed field will be freed after conversion of all constant items.
      Otherwise the result is same as before - aggregated with help of the
      item_cmp_type() function.
      
      From the Item_func_between::fix_length_and_dec() function removed the part
      which was converting date/time constants to int if possible. Now this is 
      done by the agg_cmp_type() function.
      
      The new function result_as_longlong() is added to the Item class. 
      It indicates that the item is a date/time item and result of it can be
      compared as int. Such items are date/time fields/functions.
      
      Correct val_int() methods are implemented for classes Item_date_typecast, 
      Item_func_makedate, Item_time_typecast, Item_datetime_typecast. All these
      classes are derived from Item_str_func and Item_str_func::val_int() converts
      its string value to int without regard to the date/time type of these items.
      
      Arg_comparator::set_compare_func() and Arg_comparator::set_cmp_func()
      functions are changed to substitute result type of an item with the INT_RESULT
      if the item is a date/time item and another item is a constant. This is done
      to get a correct result of comparisons like date_time_function() = string_constant.
