Enable math extension on wikitech
Closed, ResolvedPublic


We need the math extension enabled on wikitech so that we can discuss some of the mathimatical concerns of engineering more easily. Right now, we've been hacking as best we can. See for an example of a page that really needs <math> tags.

@Andrew Any particular reason why it was disabled ? Can we enable it now?

@Glaisher, yes: the goal were to disable all the unneeded extensions, to avoid an overload of not used features.

Mentioned in SAL [2016-09-02T00:21:58Z] <dereckson@tin> Synchronized wmf-config/InitialiseSettings.php: Enable Math on wikitech (T126338) (duration: 00m 47s)

Extension works, but can't currently write files, as wgMathDirectory was forced to /mnt/upload7/math.

A puppet and a config changes have been prepared to allow a local folder. That's handled in T126628.

Math extension can now write files successfully in /srv/math-images folder.

Last piece of the configuration is to serve such files as /wiki/images/math.
