      Fix bug#11868 NOT NULL ref optimization in subquery used in update must be · 81d93df1
      evgen@moonbone.local authored
      disabled if ref is built with a key from the updated table
      
      Problem was in add_not_null_conds() optimization function.
      It contains following code:
      JOIN_TAB *referred_tab= not_null_item->field->table->reginfo.join_tab;
      ...
      add_cond_and_fix(&referred_tab->select_cond, notnull);
      For UPDATE described in bug report referred_tab is 0 and dereferencing it
      crashes the server.

      Fix for BUG#9103: · a76ecc5b
      sergefp@mysql.com authored
      Don't produce data truncation warnings from within cp_buffer_from_ref(). This function
      is only used to make index search tuples and data truncation that occurs here has no
      relation with truncated values being saved into tables.
