1863481 - moz-phab on a git repo should use HEAD when git-cinnabar isn't available

Status: RESOLVED WONTFIX

(Conduit :: moz-phab, task)

Description

[Sylvestre Ledru [:Sylvestre]]

with git clone https://github.com/mozilla/gecko-dev && cd gecko-dev

I made some changes, I tried to push them to phabricator with:

$ moz-phab submit tip
Git Cinnabar extension is required to work on this repository.

According to Glandium, this is failing because moz-phab can't find the reference commit:
moz-phab needs the sha1 hg and for this, needs git-cinnabar

If git-cinnabar can't be found, maybe we should display a warning and use HEAD instead.

Comment 1

[:glob ✱]

As having git-cinnabar simplifies other repository actions it's considered mandatory; this is called out as required in our documentation.

While it's probably technically possible to implement some workarounds in moz-phab, we're likely to only be able to support the simplest of cases. Given the workaround (install cinnabar as per the docs), this isn't something we should fix.
