      A fix and test case for Bug#9096 "select doesn't return all matched · 9fcda7fc
      unknown authored
      records if prepared statements is used".
      This fix changes equality evaluation method of basic constants from
      by-name to by-value, thus effectively enabling use of parameter markers
      in some optimizations (constants propagation, evaluation of possible
      keys for query).
      
      
      mysql-test/r/ps.result:
        Test results for the test case for Bug#9096
      mysql-test/t/ps.test:
        A short test case for Bug#9096 "select doesn't return all matched records if
         prepared statements is used". The is enough to reproduce the
        glitch in update_ref_and_keys causing the bug to occur.
      sql/item.cc:
        Implement by-value equality evaluation of basic constants.
        This is needed to work with Item_param values. Until now
        Item_param was compared with other items by its name, which is always "?".
        The bug at hand showed up when an integer
        constant was created from one parameter marker (with value 200887 and
         name "?") and then compared by-name with another parameter marker
        (with value 860 and name "?"). True returned by this comparison resulted
        in a wrong table access method used to evaluate the query.
        Implement Item_param methods needed to emulate "basic constant" mode at 
        full.
      sql/item.h:
        Change declaration of basic_const_item(): now it also widens its 
        argument from const Item * to Item * if the argument is a basic constant.
        Declare eq() for all basic constatns, as long as now they 
        are compared by value, not by name. Each constant needs its own
        comparison method.
        Declarations of Item_param methods needed to fully emulate 
        a basic constant when parameter value is set.
      sql/item_func.cc:
        Fix wrong casts.

      BUG#5964 - 4.1 MERGE tables regression from 4.0 · f0e256ef
      unknown authored
      Changed the creation of the .MRG file so that only the table  name
      is written when the MyISAM table is in the same database as the
      MERGE table, a relative path is used in other cases in mysqld,
      and possibly an absolute path is used in an embedded server.
      No test case is added as the external behaviour is unchanged.
      Only the file names within the .MRG file are changed.

      Bug#8321 - myisampack bug in compression algorithm · 994674c0
      unknown authored
      This is the second of three changesets. It contains the pure bug fix.
      It also contains the second after-review fixes.
      The problem was that with gcc on x86, shifts are done modulo word size. 
      'value' is 32 bits wide and shifting it by 32 bits is a no-op.
      This was triggered by an evil distribution of character incidences. 
      A distribution of 2917027827 characters made of 202 distinct values led to
      34 occurrences of 32-bit Huffman codes.
      This might have been the first time ever that write_bits() had to write
      32-bit values. Since it can be expected that one day even 32 bits might
      be insufficient, the third changeset suggests to enlarge some variables
      to 64 bits.
