Ok, I think the problem is here: https://github.com/phacility/phabricator/blob/master/src/applications/diffusion/controller/DiffusionServeController.php#L816

I've managed to find the root of the problem, I think. Here is the actual error message that arises somwhere deep in Phabricator and then gets cut turning into non-informative ** unknown exception encountered, please report by visiting:

I still having this problem. @rafaelrabeloit, had you chance to fix or work-around this?

This isn't an actionable task. It covers too much ground, describes too many features, and most of it lacks compelling use cases.

No plan to continue on this?

I don't expect we'll need to do anything here, mostly just wanted to be able to dig up a list of these if something does come up.

Are colons (:) supported between the keywords and the objects? E.g. Fixes: adcbdef or Depends On: D123?

See PHI873, which opens a discussion around broader authentication and signatures.

@jbrownEP Hey! Was this implemented yet? I'm interested in this feature aswell.. (being able to run hook action once per push, no matter how many commits there are in the push).

The next step here is to find (almost) every instance of %T in the codebase and convert it to %R. In most cases, the conversion is trivial:

I do have a real-life example where the prose diff engine rendered a suboptimal diff. I was able to fix it by changing the maximum length of the edit distance matrix from 128 to 256.
