Get error:

Failed to parse(PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)):

I don't think we've seen these dependencies before, we'll need them in production as well as on beta labs.

Noticed some fatal error while browsing logstash (needs whitelisted labs account):

I made an edit on and it is broken indeed :(

adding Greg so updated Math support doesn't get dropped on the way to deployment

Assigned bug from labs to extension/Math to see what needs to be done to keep Math working on beta labs and in production

I can't remember offhand how we get texvc compiled on beta cluster. Seems we need the same for texvccheck.

Whenever a change is merged for mediawiki/extensions/Math.git, we trigger the Jenkins job beta-recompile-math-texvc. From the console of a job:

It runs: sudo -u mwdeploy /usr/bin/scap-recompile , which compile texvc and put it somewhere under /usr/local/apache/uncommon/

scap-recompile is provided by the debian package wikimedia-task-appserver available at ssh://

I guess we need to patch it to compile texvccheck as well.

This means we had to set $wgMathTexvcCheckExecutable to the target path as well.
