We have both Bugzilla (3.2.5.1-2) and Mediawiki (1.20.2) and I would like an easy way to create links to bug reports from a wiki page. I've noticed that the main Wikipedia site has a shortcut to bug reports; the wiki text
[[bugzilla:1234]]
renders in HTML as a link to the external Bugzilla
<a title="bugzilla:1234" class="extiw" href="https://bugzilla.wikimedia.org/show_bug.cgi?id=1234">bugzilla:1234</a>
When I try this all I get is get a link to a (non-existant) page in the bugzilla namespace
<a title="Bugzilla:1234 (page does not exist)" class="new" href="/w/index.php?title=Bugzilla:1234&action=edit&redlink=1">bugzilla:1234</a>
What am I missing? Is there a setting in LocalConfig I need to add, or an extension I need to install?
There is a setting $wgUrlProtocols
to add protocols, but I don't see how you get the extra text for the external link to appear.
