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.

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]].

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.

It is still possible to create a page with a slash as the leading character, e.g., https://en.wikipedia.org/w/index.php?title=/test&action=edit

The created page is then exists at https://en.wikipedia.org/wiki//test and is not possible to be linked with an internal link.

The original bug here was fixed ages ago. It was later reopened in 2019 due to an unrelated issue, which is IMO not a bug at all and should have a separate ticket if anyone still cares.
