      Bug#38999 valgrind warnings for update statement in function compare_record() · d2db80c8
      Sergey Glukhov authored
      Valgrind warning happpens because of uninitialized null bytes.
      In row_sel_push_cache_row_for_mysql() function we fill fetch cache
      with necessary field values, row_sel_store_mysql_rec() is called
      for this and leaves null bytes untouched.
      Later row_sel_pop_cached_row_for_mysql() rewrites table record
      buffer with uninited null bytes. We can see the problem from the
      test case:
      At 'SELECT...' we call row_sel_push...->row_sel_store...->row_sel_pop_cached...
      chain which rewrites table->record[0] buffer with uninitialized null bytes.
      When we call 'UPDATE...' statement, compare_record uses this buffer and
      valgrind warning occurs.
      The fix is to init null bytes with default values.
