For a long time Firefox Desktop development has supported both Mercurial and Git users. This dual SCM requirement places a significant burden on teams which are already stretched thin in parts. We have made the decision to move Firefox development to Git.

  • We will continue to use Bugzilla, moz-phab, Phabricator, and Lando
  • Although we’ll be hosting the repository on GitHub, our contribution workflow will remain unchanged and we will not be accepting Pull Requests at this time
  • We’re still working through the planning stages, but we’re expecting at least six months before the migration begins

APPROACH

In order to deliver gains into the hands of our engineers as early as possible, the work will be split into two components: developer-facing first, followed by piecemeal migration of backend infrastructure.

Phase One - Developer Facing

We’ll switch the primary repository from Mercurial to Git, at the same time removing support for Mercurial on developers’ workstations. At this point you’ll need to use Git locally, and will continue to use moz-phab to submit patches for review.

All changes will land on the Git repository, which will be unidirectionally synchronised into our existing Mercurial infrastructure.

Phase Two - Infrastructure

Respective teams will work on migrating infrastructure that sits atop Mercurial to Git. This will happen in an incremental manner rather than all at once.

By the end of this phase we will have completely removed support of Mercurial from our infrastructure.

    I’m only a native English speaker, so guess I could be interpreting it wrong.

    You should try being a native English reader.

    What it means is “they will not be accepting pull requests at this time.” Whether or not they are open to changing this in the future is not specified. They have not specifically stated that this is off the table, nor have they stated this is their intent.

        No. They’re just not publicly saying it’s off the table. Whether they’re entertaining it internally is a totally different question.

                How does the opinion of your supposed internal contact at mozilla affect the basic English interpretation of the public announcement?

                    You’re quite the lunatic. I’m obviously not defending GitHub PRs, or saying Mozilla should or should not use them. I said “we are not open to PRs at this time” is not the same as “we will be open to PRs in the future.” The truth of that statement has absolutely nothing to do with whether or not Mozilla is, in fact, open to using PRs in the future. But there’s no point in telling you that, because you’re clearly unhinged. Have a good life.
