      Fixed bug#17366: Unchecked Item_int results in server crash · 8ba5a687
      unknown authored
      When there is conjunction of conds, the substitute_for_best_equal_field()
      will call the eliminate_item_equal() function in loop to build final
      expression. But if eliminate_item_equal() finds that some cond will always
      evaluate to 0, then that cond will be substituted by Item_int with value ==
      0. In this case on the next iteration eliminate_item_equal() will get that 
      Item_int and treat it as Item_cond. This is leads to memory corruption and
      server crash on cleanup phase.
      
      To the eliminate_item_equal() function was added DBUG_ASSERT for checking
      that all items treaten as Item_cond are really Item_cond.
      The substitute_for_best_equal_field() now checks that if
      eliminate_item_equal() returns Item_int and it's value is 0 then this 
      value is returned as the result of whole conjunction.

      A subquery transformation changes the HAVING clause of the embedding query if the subquery contains
      a GROUP BY clause. Yet the split_sum_func2 function was not applied to the modified HAVING clause.
      This could result in wrong answers.

      WL#2486 - natural and using join according to SQL:2003 · fe24add7
      unknown authored
      * Provide backwards compatibility extension to name resolution of
        coalesced columns. The patch allows such columns to be qualified
        with a table (and db) name, as it is in 4.1.
        Based on a patch from Monty.
      
      * Adjusted tests accordingly to test both backwards compatible name
        resolution of qualified columns, and ANSI-style resolution of
        non-qualified columns.
        For this, each affected test has two versions - one with qualified
        columns, and one without.

        Put back old tests to test that coalesced columns of natural joins can be qualified.

      mysql-test/t/type_ranges.test:
        Put back old tests to test that coalesced columns of natural joins can be qualified.
      sql/sql_base.cc:
        * Applied Monty's patch for backwards compatible name resolution
          of qualified columns. The idea is:
          - When a column is qualified, search for the column in all
            tables/views underlying each natural join. In this case
            natural joins are *not* considered leaves.
          - If a column is not qualified, then consider natural joins
            as leaves, thus directly search the result columns of
            natural joins.
        * Simplified 'find_field_in_tables()' - unified two similar
          loops into one.
      sql/table.cc:
        - Removed method & members not needed after Monty's patch.
      sql/table.h:
        - Removed method & members not needed after Monty's patch.
      tests/mysql_client_test.c:

        Fixed bug #11479.
        The JOIN::reinit method cannot call setup_tables
        after the optimization phase since this function
        removes some optimization settings for joined
        tables. E.g. it resets values of the null_row flag to 0.

      Implementation of WL#2486 - · 7517d7e1
      unknown authored
      "Process NATURAL and USING joins according to SQL:2003".
      
      * Some of the main problems fixed by the patch:
        - in "select *" queries the * expanded correctly according to
          ANSI for arbitrary natural/using joins
        - natural/using joins are correctly transformed into JOIN ... ON
          for any number/nesting of the joins.
        - column references are correctly resolved against natural joins
          of any nesting and combined with arbitrary other joins.
      
      * This patch also contains a fix for name resolution of items
        inside the ON condition of JOIN ... ON - in this case items must
        be resolved only against the JOIN operands. To support such
        'local' name resolution, the patch introduces a stack of
        name resolution contexts used at parse time.
      
      NOTICE:
      - This patch is not complete in the sense that
        - there are 2 test cases that still do not pass -
          one in join.test, one in select.test. Both are marked
          with a comment "TODO: WL#2486".
        - it does not include a new test specific for the task

      sql/item.cc:
        - extra parameter to find_field_in_tables
        - find_field_in_real_table renamed to find_field_in_table
        - fixed comments/typos
      sql/item.h:
        - added [first | last]_name_resolution_table to class
          Name_resolution_context
        - commented old code
        - standardized formatting
      sql/mysql_priv.h:
        - refactored the find_field_in_XXX procedures,
        - added a new procedure for natural join table references,
        - renamed the find_field_in_XXX procedures to clearer names
      sql/sp.cc:
        - pass the top-most list of the FROM clause to setup_tables
        - extra parameter to find_field_in_tables
      sql/sql_acl.cc:
        - renamed find_field_in_table => find_field_in_table_ref
        - extra parameter to find_field_in_table_ref
        - commented old code
      sql/sql_base.cc:
        This file contains the core of the implementation of the processing
        of NATURAL/USING joins (WL#2486).
        - added many comments to old code
        - refactored the group of find_field_in_XXX procedures, and added a
          new procedure for natural joins. There is one find_field_in_XXX procedure
          per each type of table reference (stored table, merge view, or natural
          join); one meta-procedure that selects the correct one depeneding on the
          table reference; and one procedure that goes over a list of table
          referenes.
        - NATURAL/USING joins are processed through the procedures:
            mark_common_columns, store_natural_using_join_columns,
            store_top_level_join_columns, setup_natural_join_row_types.
          The entry point to processing NATURAL/USING joins is the
          procedure 'setup_natural_join_row_types'.
        - Replaced the specialized Field_iterator_XXX iterators with one
          generic iterator over the fields of a table reference.
        - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of
          the processing of natural joins in a separate set of procedures.
      sql/sql_class.h:
        - Commented old code.
      sql/sql_delete.cc:
        - Pass the FROM clause to setup_tables.
      sql/sql_help.cc:
        - pass the end name resolution table to find_field_in_tables
        - adjust the list of tables for name resolution
      sql/sql_insert.cc:
        - Changed the code that saves and restores the current context to
          support the list of tables for name resolution -
          context->first_name_resolution_table, and
          table_list->next_name_resolution_table.
          Needed to support an ugly trick to resolve inserted columns only in
          the first table.
        - Added Name_resolution_context::[first | last]_name_resolution_table.
        - Commented old code
      sql/sql_lex.cc:
        - set select_lex.parent_lex correctly
        - set correct state of the current name resolution context
      sql/sql_lex.h:
        - Added a stack of name resolution contexts to support local
          contexts for JOIN ... ON conditions.
        - Commented old code.
      sql/sql_load.cc:
        - Pass the FROM clause to setup_tables.
      sql/sql_olap.cc:
        - Pass the FROM clause to setup_tables.
      sql/sql_parse.cc:
        - correctly set SELECT_LEX::parent_lex
        - set the first table of the current name resoltion context
        - added support for NATURAL/USING joins
        - commented old code
      sql/sql_select.cc:
        - Pass the FROM clause to setup_tables.
        - Pass the end table to find_field_in_tables
        - Improved comments
      sql/sql_show.cc:
        - Set SELECT_LEX::parent_lex.
      sql/sql_update.cc:
        - Pass the FROM clause to setup_tables.
      sql/sql_yacc.yy:
        - Added support for a stack of name resolution contexts needed to
          implement name resolution for JOIN ... ON. A context is pushed
          for each new JOIN ... ON, and popped afterwards.
        - Added support for NATURAL/USING joins.
      sql/table.cc:
        - Added new class Natural_join_column to hide the heterogeneous
          representation of column references for stored tables and for
          views.
        - Added a new list TABLE_LIST::next_name_resolution_table to
          support name resolution with NATURAL/USING joins. Also added
          other members to TABLE_LIST to support NATURAL/USING joins.
        - Added a generic iterator over the fields of table references
          of various types - class Field_iterator_table_ref
      sql/table.h:
        - Added new class Natural_join_column to hide the heterogeneous
          representation of column references for stored tables and for
          views.
        - Added a new list TABLE_LIST::next_name_resolution_table to
          support name resolution with NATURAL/USING joins. Also added
          other members to TABLE_LIST to support NATURAL/USING joins.
        - Added a generic iterator over the fields of table references
          of various types - class Field_iterator_table_ref
      tests/mysql_client_test.c:
        Adjusted according to standard NATURAL JOIN syntax.

        Added a test case for bug #9516.
      item_subselect.h:
        Fixed bug #9516.
        The bug was due to that fact that the class Item_subselect
        inherited the generic implementation of the function
        not_null_tables that was not valid for the objects
        of this class. As a result evaluation of the
        not_null_tables attribute was not correct for subqueries.
        This caused invalid transformations of outer joins into
        inner joins.

      Remove TMP_TABLE_PARAM::copy_funcs_it. TMP_TABLE_PARAM is a member of JOIN which is 
      copied via memcpy, and List_iterator_fast TMP_TABLE_PARAM::copy_funcs_it ends up 
      pointing to the wrong List.

        Added test cases for bug #7351.
      item_cmpfunc.cc:
        Fixed bug #7351: incorrect result for a query with a
        subquery returning empty set.
        If in the predicate v IN (SELECT a FROM t WHERE cond)
        v is null, then the result of the predicate is either
        INKNOWN or FALSE. It is FALSE if the subquery returns
        an empty set.
      item_subselect.cc:
        Fixed bug #7351: incorrect result for a query with a
        subquery returning empty set.
        The problem was due to not a quite legal transformation
        for 'IN' subqueries. A subquery containing a predicate
        of the form
        v IN (SELECT a FROM t WHERE cond)
        was transformed into
        EXISTS(SELECT a FROM t WHERE cond AND (a=v OR a IS NULL)).
        Yet, this transformation is valid only if v is not null.
        If v is null, then, in the case when
        (SELECT a FROM t WHERE cond) returns an empty set the value
        of the predicate is FALSE, otherwise the result of the
        predicate is INKNOWN.
        The fix resolves this problem by changing the result
        of the transformation to
        EXISTS(SELECT a FROM t WHERE cond AND (v IS NULL OR (a=v OR a IS NULL)))
        in the case when v is nullable.
        The new transformation prevents applying the lookup
        optimization for IN subqueries. To make it still
        applicable we have to introduce guarded access methods.
