      BUG#8807 Select crash server · 382a8c00
      msvensson@neptunus.(none) authored
       - Add function Item_param::fix_fields which will update any subselect they are part of and indicate that the subsleect is not const during prepare phase, and thus should not be executed during prepare.

      Fix for bug#4912 "mysqld crashs in case a statement is executed · 568c6e85
      konstantin@mysql.com authored
       a second time". The bug was caused by incompatibility of
      negations elimination algorithm and PS: during first statement 
      execute a subtree with negation was replaced with equivalent 
      subtree without NOTs.
      The problem was that although this transformation was permanent, 
      items of the new subtree were created in execute-local memory.
      The patch adds means to check if it is the first execute of a
      prepared statement, and if this is the case, to allocate items
      in memory of the prepared statement.
      The implementation:
      - backports Item_arena from 5.0
      - adds Item_arena::is_stmt_prepare(), 
        Item_arena::is_first_stmt_execute().
      - deletes THD::allocate_temporary_pool_for_ps_preparing(),
        THD::free_temporary_pool_for_ps_preparing(); they
        were redundant.
      and adds a few invariants:
      - thd->free_list never contains junk (= freed items)
      - thd->current_arena is never null. If there is no
        prepared statement, it points at the thd. 
      The rest of the patch contains mainly mechanical changes and
      cleanups.

      Fix for #1992 · dff5b0a7
      hf@deer.(none) authored
      This bug happens when a query, having subselects in the fields list,
      needs temporary table.
      Item_subselect::get_tmp_table_item isn't implemented and just returns
      *this. So the tmp_table_item takes value not from temporary but
      from original table.
