On Special:Version, there is a link to a revision (765738d) on Phabricator (Diffusion). Every link by other extensions appears to work and the revision is already available through Diffusion in the extension.
@Rillke hi thanks for reporting this, the reason is because this repo has to be added to the gerrit redirection link. Repos have to be manually added to it, @demon runs the script that does that.
@mmodell can I add you to task please.
Oh I believe this is because it needs a : since it isent using a callsign.
If we give it a callsign and update the callsign map this should fix the problem.
Looks fixed to me.
