      Bug#14980 - COUNT(*) incorrect on MyISAM table with certain INDEX · d0c6eb88
      ingo@mysql.com authored
      For "count(*) while index_column = value" an index read
      is done. It consists of an index scan and retrieval of
      each key.
      
      For efficiency reasons the index scan stores the key in
      the special buffer 'lastkey2' once only. At the first 
      iteration it notes this fact with the flag 
      HA_STATE_RNEXT_SAME in 'info->update'.
      
      For efficiency reasons, the key retrieval for blobs
      does not allocate a new buffer, but uses 'lastkey2'...
      
      Now I clear the HA_STATE_RNEXT_SAME flag whenever the 
      buffer has been polluted. In this case, the index scan
      copies the key value again (and sets the flag again).

      BUG#6151 - myisam index corruption. · 0d044c68
      ingo@mysql.com authored
      Removed the assumption of a certain key order.
      Since 4.1, keys are padded with blanks for comparison.
      Hence, shorter keys sort behind longer keys, if the
      data bytes have values below BLANK.
