      Fixed bug #24856: the result set of a ROLLUP query with DISTINCT could lack · eec5a606
      unknown authored
      some rollup rows (rows with NULLs for grouping attributes) if GROUP BY
      list contained constant expressions.
      
      This happened because the results of constant expressions were not put
      in the temporary table used for duplicate elimination. In fact a constant
      item from the GROUP BY list of a ROLLUP query can be replaced for an
      Item_null_result object when a rollup row is produced . 
      
      Now the JOIN::rollup_init function wraps any constant item referenced in
      the GROYP BY list of a ROLLUP query into an Item_func object of a special
      class that is never detected as constant item. This ensures creation of
      fields for such  constant items in temporary tables and guarantees right
      results when the result of the rollup operation first has to be written
      into a temporary table, e.g. in the cases when duplicate elimination is
      required.

        Itroduced class Item_func_rollup_const derived from Item_func. The object of
        this class are never detected as constant items.
        We use them for wrapping constant items from the GROUP BY list of any ROLLUP
        query. This wrapping allows us to ensure writing constant items into temporary
        tables whenever the result of the ROLLUP operation has to be written into a
        temporary table, e.g. when ROLLUP is used together with DISTINCT in the SELECT
        list.

      INSERT...ON DUPLICATE KEY UPDATE may cause error 1032: 
      "Can't find record in ..." if we are inserting into
      InnoDB table unique index of partial key with
      underlying UTF-8 string field.
      
      This error occurs because INSERT...ON DUPLICATE uses a wrong
      procedure to copy string fields of multi-byte character sets
      for index search.

      This bug occurs when error message length exceeds allowed limit: my_error()
      function outputs "%s" sequences instead of long string arguments.
      
      Formats like %-.64s are very common in errmsg.txt files, however my_error()
      function simply ignores precision of those formats.

      BUG#25951 - ignore/use index does not work with fulltext · e6c8d34c
      unknown authored
      IGNORE/USE/FORCE INDEX hints were honored when choosing FULLTEXT
      index.
      
      With this fix these hints are ignored. For regular indexes we may
      perform table scan instead of index lookup when IGNORE INDEX was
      specified. We cannot do this for FULLTEXT in NLQ mode.

      BUG#24342 - Incorrect results with query over MERGE table · d64d7f4a
      unknown authored
      MERGE engine may return incorrect values when several representations
      of equal keys are present in the index. For example "groß" and "gross"
      or "gross" and "gross " (trailing space), which are considered equal,
      but have different lengths.
      
      The problem was that key length was not recalculated after key lookup.
      
      Only MERGE engine is affected.
      
      
      myisam/mi_rkey.c:
        info->lastkey gets rewritten by mi_search. Later we recalculate found lastkey
        length. This is done to make sure that mi_rnext_same gets true, found (not
        searched) lastkey length. Searched and found key lengths may be different,
        for example in case searched key is "groß" and found is "gross" or in case
        a key has trailing spaces.
        
        Unfortunately we recalculate found lastkey length only for first
        underlying table. To recalculate found key length for non-first underlying
        table we need to know how much key segments were used to create this key.
        
        When mi_rkey is called for first underlying table of a merge table, store
        offset to last used key segment.
        
        Restore last_used_keyseg variable when mi_rkey is called for non-first
        underlying table.
      myisam/myisamdef.h:
        Added last_used_keyseg variable to MI_INFO. It is used by merge engine to calculate
        key length.
      myisammrg/myrg_rkey.c:
        Pass last used key segment returned by first table key read to other
        table key reads.
      mysql-test/r/merge.result:
        A test case for bug#24342.
      mysql-test/t/merge.test:
        A test case for bug#24342.
