  r6949 | mmakela | 2010-04-06 16:11:46 +0300 (Tue, 06 Apr 2010) | 7 lines

  branches/zip: Add debug checks to track down Issue #461.

  dict_table_check_for_dup_indexes(): Add the flag tmp_ok.  If !tmp_ok,
  check that no index name starts with TEMP_INDEX_PREFIX.

  ha_innobase::add_index(), ha_innobase::prepare_drop_index(),
  ha_innobase::final_drop_index(): Call dict_table_check_for_dup_indexes().
