BUG MIGRATED FROM SOURCEFORGE
http://sourceforge.net/tracker/index.php?func=detail&aid=977535&group_id=34373&atid=411192
Originally submitted by Nobody/Anonymous - nobody  2004-06-22 17:04


For redirect pages that go to a page title that begins
with a '/', when the redirect page is viewed with
&redirect=no, the '/' is not shown in the link and
these redirects are seen as broken by
Special:Maintenance&subfunction=brokenredirects

An example of this is:
http://en.wikipedia.org/w/wiki.phtml?title=Gcwi_language&redirect=no

which displays a link to [[Gwi language]] (which does
not exist) instead of [[/Gwi language]]. The redirects
works if &redirect=yes

Actually, the problem is wider than you think: no link can
point at a page beginning with "/". The reason is that in a
namespace where subpages are legal (e.g.
[[Wikipedia:Sandbox]]) it will be treated as a subpage link
(e.g. to [[Wikipedia:Sandbox/Gwi language]]). In Wikipedia's
article namespace, subpages are disabled, so the software
removes the slash as being erroneous.

The bug is that you were able to create a page with such a
title in the first place. (And that the redirect *does*
work, even though the links don't; a consequence of the
rather ad hoc parser, I suspect).

Workaround: move the pages so they don't begin with slashes
- awkward, I know but they won't be the only ones - see
http://en.wikipedia.org/wiki/Wikipedia:List_of_pages_whose_correc
t_title_is_not_allowed_by_MediaWiki

This bug should stay open until someone blocks such pages
from being created accidentally.

This page title should not work under the current schema.
That is does is erroneous, as it can't be reached through
normal links:
http://en.wikipedia.org/wiki//Gwi_language

Renamed bug report to reflect the root problem.

Comment 2 Wil Mahan 2004-09-13 22:07:31 UTC
Hi, my patch at bug 428 should allow articles beginning with slash to be linked
normally, although it only applies when subpages are disabled.

Tested patch that makes any title with / as the first character invalid
Comment 5 Aryeh Gregor (not reading bugmail, please e-mail directly) 2006-11-06 04:43:53 UTC
Applied in r17454.
Comment 6 Rotem Liss 2006-11-06 13:22:43 UTC
Reverted on 17456 by Simetrical, because several pages with this name are
already exist.
Comment 7 Rob Church 2006-11-06 20:08:49 UTC
Don't we have a script to clean up dud titles and rename the pages?
Comment 8 Aryeh Gregor (not reading bugmail, please e-mail directly) 2006-11-07 02:51:49 UTC
Probably, so if anyone would care to run it . . .
Comment 9 Tim Starling 2006-11-07 04:00:15 UTC
Why not fix the linking code, instead of disabling initial slashes? In cases
where there is a conflict with subpage syntax, you can just specify the
namespace, e.g. [[User:/Foo]] or [[:/Foo]]. 
Comment 10 Aryeh Gregor (not reading bugmail, please e-mail directly) 2006-11-07 04:08:18 UTC
The linking code appears to work fine at present, although if you're in a
namespace with subpages it requires the leading colon.  Should either be FIXED
or WONTFIX.
Comment 11 Brion Vibber 2006-11-28 01:48:59 UTC

Comment 12 River Tarnell 2007-05-21 16:45:52 UTC
can't reproduce the original behaviour here, presumably it's been fixed at some point.
