mediawiki/extensions/Math
mark parsertests with option 'math'

That will at least skips math text when texvc is not installed.

list of dependencies provided by wikimedia-task-appserver

In production we use the scap-recompile shell script which is provided by the wikimedia-task-appserver Debian package:

$ dpkg -S scap-recompile
wikimedia-task-appserver

That packages is in operations/debs/wikimedia-task-appserver.git and provides a bunch of dependencies (attached). That is how we installed distributions packages before the puppet era.

I dont think we should install that package on the Jenkins machine. Either we need a new package or migrate part of its content to a puppet manifest. From there, we will be able to get all the requirements installed on Jenkins boxes and thus compile texvc.

Attached:

I recently added a role::math puppet class for the mediawiki-vagrant project that seems to work. The gerrit patch can be seen at https://gerrit.wikimedia.org/84860/.

This configuration may be missing something as I mostly just followed https://www.mediawiki.org/wiki/Manual:Enable_TeX and tweaked until I could run the unit tests and render a copy of https://meta.wikimedia.org/wiki/Help:Formula locally.

Does the https://integration.wikimedia.org/ci/job/beta-recompile-math-texvc-eqiad/ jenkins job do the things this bug was opened to track or is there still additional work that needs to be done to close this?

Bryan: the job you reference compiles and deploy on the test cluster. This bug is about doing the compilation when a patch is proposed. That is not that much of a priority though since I don't see anyone merging some caml that does not compile. Lowering priority.
