      Fixed bug #29205. · bf7a9ad2
      unknown authored
      When a UNION statement forced conversion of an UTF8
      charset value to a binary charset value, the byte
      length of the result values was truncated to the
      CHAR_LENGTH of the original UTF8 value.
      
      
      sql/item.cc:
        Fixed bug #29205.
        The calculation of data length was modified in
        the Item_type_holder::join_types method to take into
        account possible conversion of a multibyte charset
        value to a binary charset value, when each
        multibyte character is converted into a sequence
        of bytes (not to a single byte of binary charset).

      Bug#29261: Sort order of the collation wasn't used when comparing trailing · 80824e67
      unknown authored
      spaces.
      
      When the my_strnncollsp_simple function compares two strings and one is a prefix
      of another then this function compares characters in the rest of longer key
      with the space character to find whether the longer key is greater or less.
      But the sort order of the collation isn't used in this comparison. This may
      lead to a wrong comparison result, wrongly created index or wrong order of the
      result set of a query with the ORDER BY clause.
      
      Now the my_strnncollsp_simple function uses collation sort order to compare
      the characters in the rest of longer key with the space character.

      Bug#27333: subquery grouped for aggregate of outer · 7d6c4d8d
      unknown authored
      query / no aggregate of subquery
       The optimizer counts the aggregate functions that 
       appear as top level expressions (in all_fields) in 
       the current subquery. Later it makes a list of these
       that it uses to actually execute the aggregates in
       end_send_group().
       That count is used in several places as a flag whether
       there are aggregates functions.
       While collecting the above info it must not consider
       aggregates that are not aggregated in the current 
       context. It must treat them as normal expressions 
       instead. Not doing that leads to incorrect data about
       the query, e.g. running a query that actually has no
       aggregate functions as if it has some (and hence is
       expected to return only one row).
       Fixed by ignoring the aggregates that are not aggregated
       in the current context. 
       One other smaller omission discovered and fixed in the 
       process : the place of aggregation was not calculated for
       user defined functions. Fixed by calling 
       Item_sum::init_sum_func_check() and 
       Item_sum::check_sum_func() as it's done for the rest of 
       the aggregate functions.

      Fix for BUG#10491: Server returns data as charset binary · 003f416f
      unknown authored
      SHOW CREATE TABLE or SELECT FROM I_S.
      
      Actually, the bug discovers two problems:
        - the original query is not preserved properly. This is the problem
          of BUG#16291;
        - the resultset of SHOW CREATE TABLE statement is binary.
      
      This patch fixes the second problem for the 5.0.
      
      Both problems will be fixed in 5.1.

      sql/item.h:
        Use utf8_general_ci instead of binary collation by default,
        because for views and base tables utf8 is the character set
        in which their definition is stored. For system constants
        it's the default character set, and for other objects
        (routines, triggers), no character set is stored, and
        therefore no character set is known, so returning utf8
        is just as good as any non-binary character set.
        This latter problem is fixed in 5.1 by 16291. In 5.1
        we will return the "real" character set.

      Bug #26642: create index corrupts table definition in .frm · 8f16be87
      unknown authored
        
        Thanks to Martin Friebe for finding and submitting a fix for this bug!
        
        A table with maximum number of key segments and maximum length key name
        would have a corrupted .frm file, due to an incorrect calculation of the
        complete key length.  Now the key length is computed correctly (I hope) :-)
        
        MyISAM would reject a table with the maximum number of keys and the maximum
        number of key segments in all keys.  It would allow one less than this total
        maximum.  Now MyISAM accepts a table defined with the maximum.  (This is a
        very minor issue.)

      Fixed bug #29251. · 5e0349cc
      unknown authored
      Sometimes special 0 ENUM values was ALTERed to normal
      empty string ENUM values.
      
      Special 0 ENUM value has the same string representation
      as normal ENUM value defined as '' (empty string).
      The do_field_string function was used to convert
      ENUM data at an ALTER TABLE request, but this
      function doesn't care about numerical "indices" of
      ENUM values, i.e. do_field_string doesn't distinguish
      a special 0 value from an empty string value.
      
      A new copy function called do_field_enum has been added to
      copy special 0 ENUM values without conversion to an empty
      string.
      
      
      sql/field_conv.cc:
        Fixed bug #29251.
        The Copy_field::get_copy_func method has been modified to
        return a pointer to the do_field_enum function if a conversion
        between two columns of incompatible enum types is required.
        The do_field_enum function has been added for the correct
        conversion of special 0 enum values.

      an assertion abort for a debug version and wrong results for non-debug

      The problem occurred because the function _mi_pack_key stripped off 
      the trailing spaces from binary search keys while the function _mi_make_key
      did not do it when keys were inserted into the index.

      If one sets MYSQL_READ_DEFAULTS_FILE and MYSQL_READ_DEFAULT_GROUP options
      after mysql_real_connect() called with that MYSQL instance,
      these options will affect next mysql_reconnect then.
      As we use a copy of the original MYSQL object inside mysql_reconnect,
      and mysql_real_connect frees options.my_cnf_file and _group strings,
      we will free these twice when we execute mysql_reconnect with the
      same MYSQL for the second time.

      Bug #29154: LOCK TABLES is not atomic when >1 InnoDB tables are locked · 6a1657ae
      unknown authored
        LOCK TABLES takes a list of tables to lock. It may lock several 
        tables successfully and then encounter a tables that it can't lock, 
        e.g. because it's locked. In such case it needs to undo the locks on
        the already locked tables. And it does that. But it has also notified
        the relevant table storage engine handlers that they should lock.
        The only reliable way to ensure that the table handlers will give up
        their locks is to end the transaction. This is what UNLOCK TABLE 
        does : it ends the transaction if there were locked tables by LOCK 
        tables.
        It is possible to end the transaction when the lock fails in 
        LOCK TABLES because LOCK TABLES ends the transaction at its start 
        already. 
        Fixed by ending (again) the transaction when LOCK TABLES fails to
        lock a table.

      Fixed bug #25602. A query with DISTINCT in the select list to which · 09e2b603
      unknown authored
      the loose scan optimization for grouping queries was applied returned 
      a wrong result set when the query was used with the SQL_BIG_RESULT
      option.
      
      The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
      queries instead of employing a suitable index. The current loose scan
      optimization is applied only for one table queries when the suitable
      index is covering. It does not make sense to use sort algorithm in this
      case. However the create_sort_index function does not take into account
      the possible choice of the loose scan to implement the DISTINCT operator
      which makes sorting unnecessary. Moreover the current implementation of
      the loose scan for queries with distinct assumes that sorting will
      never happen. Thus in this case create_sort_index should not call
      the function filesort.

      INSERT into table from SELECT from the same table
      with ORDER BY and LIMIT was inserting other data
      than sole SELECT ... ORDER BY ... LIMIT returns.
      
      One part of the patch for bug #9676 improperly pushed
      LIMIT to temporary table in the presence of the ORDER BY
      clause.
      That part has been removed.
