      Fixed LP bug #826279. · 9f45b1e2
      Igor Babaev authored
      When the WHERE/HAVING condition of a subquery has been transformed
      by the optimizer the pointer stored the 'where'/'having' field 
      of the SELECT_LEX structure used for the subquery must be updated
      accordingly. Otherwise the pointer may refer to an invalid item.
      This can lead to the reported assertion failure for some queries
      with correlated subqueries

      Fix bug lp:813473 · 4dfa8e5d
      unknown authored
      The bug is a duplicate of MySQL's Bug#11764086,
      however MySQL's fix is incomplete for MariaDB, so
      this fix is slightly different.
      
      In addition, this patch renames
      Item_func_not_all::top_level() to is_top_level_item()
      to make it in line with the analogous methods of
      Item_in_optimizer, and Item_subselect.
      
      Analysis:
      It is possible to determine whether a predicate is
      NULL-rejecting only if it is a top-level one. However,
      this was not taken into account for Item_in_optimizer.
      As a result, a NOT IN predicate was erroneously
      considered as NULL-rejecting, and the NULL-complemented
      rows generated by the outer join were rejected before
      being checked by the NOT IN predicate.
      
      Solution:
      Change Item_in_optimizer to be considered as
      NULL-rejecting only if it a top-level predicate.

      opt_range.cc: modified print_key() so that it doesn't do memory re-allocs when
      printing multipart keys over varchar columns. When it did, key printout in 
      debug trace was interrupted with my_malloc/free printouts.

      BUG#826935 Assertion `!table || (!table->read_set || bitmap_is_set(table->read_set, field_index))' failed
      - add_ref_to_table_cond() should not just overwrite pre_idx_push_select_cond
        with the contents tab->select_cond.
        pre_idx_push_select_cond exists precisely for the reason that it may contain
        a condition that is a strict superset of what is in tab->select_cond. 
        The fix is to inject generated equality into pre_idx_push_select_cond.

      The value of maybe_null flag should be saved for the second execution
      of a prepared statement from SELECT that uses an outer join.
