How Github implemented its Pull Request feature
git, github, gitorious, implementation, version-control
Solution
They store the name of the branch from which you want to pull and generate diffs using `git diff ^target-branch pull-head`. When you accept the pull request, they simply run `git merge pull-base`.
They do not use `git request-pull`. There is even a discussion where Linus Torwalds insults them for it :)
Problem
I have question about GitHub — how they implemented Pull Request feature. Git SCM itself has git-request-pull commands. According to this answer GitHub can use git-request-pull and git-format-patch to do this. How they implemented this feature? And what about Gitorious and Gitlab? How they did the same?
