      Bug#36023: Incorrect handling of zero length caused an assertion to fail. · 51b980ad
      unknown authored
      When a zero length is provided to the my_decimal_length_to_precision
      function along with unsigned_flag set to false it returns a negative value.
      For queries that employs temporary tables may cause failed assertion or
      excessive memory consumption while temporary table creation.
      
      Now the my_decimal_length_to_precision and the my_decimal_precision_to_length
      functions take unsigned_flag into account only if the length/precision
      argument is non-zero.

      Fixed bug#36005: server crashes inside NOT IN clause subquery with · 5bb4282e
      unknown authored
                       impossible WHERE/HAVING clause
                       (subselect_single_select_engine::exec).
      
      Allocation and initialization of joined table list t1, t2... of
      subqueries like:
      
          NOT IN (SELECT ... FROM t1,t2,... WHERE 0)
      
      is optimized out, however server tries to traverse this list.
      
      
      mysql-test/r/subselect3.result:
        Added test case for bug#36005.
      mysql-test/t/subselect3.test:
        Added test case for bug#36005.
      sql/sql_select.cc:
        Fixed bug#36005.
        
        1. JOIN::prepare initializes JOIN::table counter (actually a size
           of the JOIN::join_tab array) and sets it to a number of joined tables.
        
        2. The make_join_statistics function (when called from JOIN::optimize)
           allocates and fills the JOIN::join_tab array.
           However, when optimizing subselect has impossible (definite false)
           WHERE or HAVING clause, optimizer skips call to make_join_statistics
           and leaves JOIN::join_tab == NULL.
        
        3. subselect_single_select_engine::exec does traversal of the JOIN::join_tab
           array and the server dies because array is not allocated but array
           counter is greater than 0.
        
        The JOIN::optimize method has been modified to reset the JOIN::table
        counter to 0 in cause of impossible WHERE/HAVING clause.

      Fixed bug #35993: memory corruption and crash with multibyte conversion. · 39e9cf67
      unknown authored
      Grouping or ordering of long values in not indexed BLOB/TEXT columns
      with GBK or BIG5 charsets crashes the server.
      
      MySQL server uses sorting (the filesort procedure) in the temporary
      table to evaluate the GROUP BY clause in case of lack of suitable index.
      That procedure takes into account only first @max_sort_length bytes
      (system variable, usually 1024) of TEXT/BLOB sorting key string.
      The my_strnxfrm_gbk and my_strnxfrm_big5 fill temporary keys
      with data of whole blob length instead of @max_sort_length bytes
      length. That buffer overrun has been fixed.

        Added test case for bug #35993.

      Fix for Bug#35469: server crash with LOAD DATA INFILE to a VIEW. · a6f04bb3
      unknown authored
      The problem was that LOAD DATA code (sql_load.cc) didn't take into
      account that there may be items, representing references to other
      columns. This is a usual case in views. The crash happened because
      Item_direct_view_ref was casted to Item_user_var_as_out_param,
      which is not a base class.
      
      The fix is to
        1) Handle references properly;
        2) Ensure that an item is treated as a user variable only when
           it is a user variable indeed;
        3) Report an error if LOAD DATA is used to load data into
           non-updatable column.

        Update result file.

      Bug#27219: Aggregate functions in ORDER BY. · 9e65582b
      unknown authored
      Mixing aggregate functions and non-grouping columns is not allowed in the
      ONLY_FULL_GROUP_BY mode. However in some cases the error wasn't thrown because
      of insufficient check.
      
      In order to check more thoroughly the new algorithm employs a list of outer
      fields used in a sum function and a SELECT_LEX::full_group_by_flag.
      Each non-outer field checked to find out whether it's aggregated or not and
      the current select is marked accordingly.
      All outer fields that are used under an aggregate function are added to the
      Item_sum::outer_fields list and later checked by the Item_sum::check_sum_func
      function.
