      Fix for bug #32103: optimizer crash when join on int and mediumint with · 70cbef8e
      unknown authored
      variable in where clause.
      
      Problem: the new_item() method of Item_uint used an incorrect
      constructor. "new Item_uint(name, max_length)" calls
      Item_uint::Item_uint(const char *str_arg, uint length) which assumes the
      first argument to be the string representation of the value, not the
      item's name. This could result in either a server crash or incorrect
      results depending on usage scenarios.
      
      Fixed by using the correct constructor in new_item():
      Item_uint::Item_uint(const char *str_arg, longlong i, uint length).

      Bug#31588: buffer overrun when setting variables · 52162bd3
      unknown authored
      Buffer used when setting variables was not dimensioned to accomodate
      trailing '\0'. An overflow by one character was therefore possible.
      CS corrects limits to prevent such overflows.
      
      
      mysql-test/r/variables.result:
        Try to overflow buffer used for setting system variables.
        Unpatched server should throw a valgrind warning here.
        Actual value and error message irrelevant, only length counts.
      mysql-test/t/variables.test:
        Try to overflow buffer used for setting system variables.
      sql/set_var.cc:
        Adjust maximum number of characters we can store in 'buff' by one
        as strmake() will write a terminating '\0'.

      Fix for bug #31174: "Repair" command on MyISAM crashes with small · 0aba4cc9
      unknown authored
      myisam_sort_buffer_size.
      
      An incorrect length of the sort buffer was used when calculating the
      maximum number of keys. When myisam_sort_buffer_size is small enough,
      this could result in the number of keys < number of
      BUFFPEK structures which in turn led to use of uninitialized BUFFPEKs.
      
      Fixed by correcting the buffer length calculation.
      
      
      myisam/sort.c:
        Use a correct buffer length when calculating the maximum number of keys.
        Assert that for each BUFFPEK structure there is at least one
        corresponding key. Otherwise we would fail earlier and not reach
        merge_buffers().

        Added a test case for bug #31174.

      Bug #30286 spatial index cause corruption and server crash! · ffdd1f61
      unknown authored
      As the result of DOUBLE claculations can be bigger
      than DBL_MAX constant we use in code, we shouldn't use this constatn
      as a biggest possible value.
      Particularly the rtree_pick_key function set 'min_area= DBL_MAX' relying
      that any rtree_area_increase result will be less so we return valid
      key. Though in rtree_area_increase function we calculate the area
      of the rectangle, so the result can be 'inf' if the rectangle is
      huge enough, which is bigger than DBL_MAX.
      
      Code of the rtree_pick_key modified so we always return a valid key.

      BUG#30590 - delete from memory table with composite btree primary key · dfc87e8c
      unknown authored
      DELETE query against memory table with btree index may remove
      not all matching rows. This happens only when DELETE uses
      index read method to find matching rows. E.g. for queries
      like DELETE FROM t1 WHERE a=1.
      
      Fixed by reverting fix for BUG9719 and applying proper solution.
      
      
      heap/hp_delete.c:
        Reverted fix for BUG9719 as it makes queries like
        DELETE FROM t1 WHERE a=1 to remove not all matching
        rows (assuming this is memory table and there is btree
        key over `a`).
        
        This happens because we calculate info->lastkey_len in
        heap_rkey(). When we enter heap_rnext(), info->lastkey_len
        is 0 (set by hp_rb_delete_key()). We need to preserve
        info->lastkey_len in this situation, otherwise
        tree_search_key() will always return smallest value in
        a tree.
      heap/hp_rfirst.c:
        If we're performing index_first on a table that was taken from
        table cache, info->lastkey_len is initialized to previous query.
        Thus we set info->lastkey_len to proper value for subsequent
        heap_rnext() calls.
        This is needed for DELETE queries only, otherwise this variable is
        not used.
        Note that the same workaround may be needed for heap_rlast(), but
        for now heap_rlast() is never used for DELETE queries.
      heap/hp_rnext.c:
        An optimization for DELETE queries that use index_first()/index_next().
        Use faster tree_search_edge() instead of tree_search_key().
      mysql-test/r/heap_btree.result:
        A test case for BUG#30590.
      mysql-test/t/heap_btree.test:
        A test case for BUG#30590.
