- // Modern MediaWiki has the content for deleted revs in the 'text'
- // table using fields old_text and old_flags. But revisions deleted
- // pre-1.5 store the content in the 'archive' table directly using
- // fields ar_text and ar_flags, and no corresponding 'text' row. So
- // we have to LEFT JOIN and fetch all four fields, plus ar_text_id
- // to be able to tell the difference.
