      Igor's fix from sp1r-igor@olga.mysql.com-20080330055902-07614:
        There could be observed the following problems:
        1. EXPLAIN did not mention pushdown conditions from on expressions in the 
        'extra' column.  As a result if a query had no where conditions pushed 
        down to a table, but had on conditions pushed to this table the 'extra' 
        column in the EXPLAIN for the table missed 'using where'.
        2. Conditions for ref access were not eliminated from on expressions 
        though such conditions were eliminated from the where condition.

      Fixed bug #29604. · 07c0e6af
      unknown authored
      A bug in the restore_prev_nj_state function allowed interleaving 
      inner tables of outer join operations with outer tables. With the
      current implementation of the nested loops algorithm it could lead
      to wrong result sets for queries with nested outer joins.
      Another bug in this procedure effectively blocked evaluation of some
      valid execution plans for queries with nested outer joins.

       - added join cache indication in EXPLAIN (Extra column).
       - prefer filesort over full scan over 
         index for ORDER BY (because it's faster).
       - when switching from REF to RANGE because
         RANGE uses longer key turn off sort on
         the head table only as the resulting 
         RANGE access is a candidate for join cache
         and we don't want to disable it by sorting

      BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join · c2ff0cc4
      unknown authored
       Two problems here:
      
       Problem 1:
      
       While constructing the join columns list the optimizer does as follows:
        1. Sets the join_using_fields/natural_join members of the right JOIN 
         operand.
        2. Makes a "table reference" (TABLE_LIST) to parent the two tables.
        3. Assigns the join_using_fields/is_natural_join of the wrapper table
         using join_using_fields/natural_join of the rightmost table
        4. Sets join_using_fields to NULL for the right JOIN operand.
        5. Passes the parent table up to the same procedure on the upper 
         level.
      
       Step 1 overrides the the join_using_fields that are set for a nested 
       join wrapping table in step 4.
       Fixed by making a designated variable SELECT_LEX::prev_join_using to 
       pass the data from step 1 to step 4 without destroying the wrapping 
       table data.
      
       Problem 2:
      
       The optimizer checks for ambiguous columns while transforming 
       NATURAL JOIN/JOIN USING to JOIN ON. While doing that there was no
       distinction between columns that are used in the generated join
       condition (where ambiguity can be checked) and the other columns
       (where ambiguity can be checked only when resolving references
       coming from outside the JOIN construct itself).
       Fixed by allowing the non-USING columns to be present in multiple 
       copies in both sides of the join and moving the ambiguity check 
       to the place where unqualified references to the join columns are
       resolved (find_field_in_natural_join()).

      Fixed bug #24345. · ac347645
      unknown authored
      This bug appeared after the patch for bug 21390 that had added some code
      to handle outer joins with no matches after substitution of a const
      table in an efficient way. That code as it is cannot be applied to the case
      of nested outer join operations. Being applied to the queries with
      nested outer joins the code can cause crashes or wrong result sets.
      The fix blocks row substitution for const inner tables of an outer join
      if the inner operand is not a single table.

        A table is never considered as a const table if it is used in a nested join 
        that serves as an inner operand of an outer join.

      WL#2486 - natural and using join according to SQL:2003 · 1647932c
      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. 
      
      
      mysql-test/include/ps_query.inc:
        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:
        Put back old tests to test that coalesced columns of natural joins can be qualified.

      Implementation of WL#2486 - · bcc00c1f
      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

        - 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 case for bug #4976 when one of the inner tables is empty.

        Reversed the previous change of the erronious fix for bug #4976.
      sql_select.cc:
        The previous fix for bug 4976 was reversed as it
        erroniously converted an outer join into an innner join
        when on_expression does not refer to outer tables.
        This is not valid if inner tables return an empty set.
        Setting dependency on outer tables was added for the above cases.
        To fix the crash in the test case of bug #4976  
        a guard was added that blocks running the crashing code for
        nested outer joins.

        Post-merge fixes for nested joins.
        The join_tab_cmp function in sql_select has been changed.
      join_nested.result:
        Post-merge fixes for nested joins. 
        The join_tab_cmp function in sql_select has been changed
      sql_select.cc:
        Post-merge fixes for nested joins.
        Avoided re-execution of eliminate_not_funcs and simplify_joins
        in optimize_cond.
        Changed the join_tab_cmp function to take into account
        the dependent relation.
      sql_lex.cc, sql_lex.h:
        Added the first_cond_optimization flag to st_select_lex to avoid
        re-execution of some optimizations in optimize_cond.
      sql_base.cc:
        Post-merge fixes for nested joins. 
        Fixed problems with a proper column list substituted for '*' in
        queries with natural joins.
