Differences between Phabricator and GitHub

• Phabricator plugin for Jenkins hasn't been updated for almost 2 years according to this community post.
• Harbormaster is the CI tool in Phabricator but their own user guide calls out that "Harbormaster is not a mature application." along with a list of limitations. Haskell has also reported Harbormaster breaking.
• Phabricator uses a pre-commit workflow, where the reviews are done before the commit is pulled into the repo. Basically, they stay as change sets until approved. GitHub is post-commit by default, where the commits are already part of the history and simply tied to a branch when merged.

Differences between Mercurial and Git

• Mercurial is a distributed version control system very similar to Git.
• While Mercurial may be easier at first because it offers more low-level commands, users must edit the mercurial config file to activate the advanced features they like.
• Mercurial's UX kind of similar to SVN, Git's UX is completely different which causes a steeper learning curve.

Phabricator automatically assigns Group Reviewers to a PR, I don't know there must be a config of some sort probably using file path, do we have something similar in Github?

Anyone can review the PR from Group Reviewers and unblock it.

@mukuljainx this gist is quite old! But since it's creation GitHub has come out with a whole host of things like codeowners

That's awesome, thanks @brntbeer
