      Free unused JOINs early even if using subqueries. · f6edb3f5
      unknown authored
      
      sql/sql_select.cc:
        According to the conclusion made in the previous patch, we can widen
        the range of cases when JOINs are fully freed early, and include 
        subqueries to it.

      Remove an unrelevant assert. · 024d232a
      unknown authored
      
      sql/sql_select.cc:
        This assert is not relevant because:
        - the correct assert is DBUG_ASSERT(! (full && sl->uncacheable)) 
          (prevents freeing of uncacheable JOINs), it breaks view.test
        - it seems we can free internal JOINs, even if they are uncacheable:
          if the top level join is evaluated, we're not going to need  the
          internal joins any more

      - don't call JOIN::join_free(1) twice for every join in JOIN::cleanup(). · 97e78d60
      unknown authored
      The reason it happened was that both, JOIN::cleanup() and JOIN::join_free(),
      went over all nested joins and called cleanup/join_free for them.
      For that:
      - split recursive and non-recursive parts of JOIN::cleanup() and
      JOIN::join_free()
      - rename JOIN::cleanup to JOIN::destroy, as it actually destroys its
        argument
      - move the recursive part of JOIN::cleanup to st_select_lex::cleanup
      - move the non-recursive part of JOIN::join_free to the introduced
        method JOIN::cleanup().
      
      
      sql/sql_lex.h:
        Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup()
      sql/sql_select.cc:
        - remove two unused arguments from return_zero_rows
        - split JOIN::join_free and JOIN::cleanup to recursive and non-recursive
          parts.
        - note, the assert in JOIN::join_free _does_ fail in having.test.
          We have two options: a) propagate `full' flag to the nested joins.
          We did it before, and this patch didn't change it. If so, we 
          can end up cleaning up an uncacheable JOIN (that is, the join that
          we might need again).
          b) evaluate own 'full' flag on every level. In this case, we might
          end up with tables freed in mysql_unlock_read_tables, but not
          cleaned up properly, and this may be even worse. The test suite
          passes with both approaches, but not with the assert.
      sql/sql_select.h:
        - declarations for JOIN::cleanup() and JOIN::join_free()
      sql/sql_union.cc:
        Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup():
        move the recursive part of JOIN::cleanup to it.

        Bug#8321 - myisampack bug in compression algorithm
        Enlarged the variables which hold Huffman codes to
        ulonglong and adjusted the functions accordingly.
        Added test code for long Huffman codes.
        Enlarged the distinct column values buffer (tree_buff)
        and added checks to stay in its range.
        Added statistics and trace prints.
        Added a lot of comments.
      mysys/tree.c:
        Bug#8321 - myisampack bug in compression algorithm
        Added a check against overflow of the tree element count.
        The tree element count is only 31 bits, but sometimes
        used for big numbers. There is however no application yet,
        which relies on exact tree element counts.
