My project on GitHub has received a pull request. The pull request only partly fixes the issue that it's addressing. I've pulled in the changes to a local branch and added some commits of my own.
I'd now like to push those commits back to my remote repo and have them show up on the pull request, but without merging them into the target branch. I'd like to keep the pull request open for further review and discussion, and potentially further commits.
Is there a way I can add commits to the pull request without merging them into the target branch and therefore closing the pull request?
As long as the original author has clicked the checkbox in the bottom right:
If that box is checked, then you can push back to the original branch without needing to add a remote by using:
git push git@github.com:user/repo local_branch_name:remote_branch_name
This is particularly useful if you're using a tool like hub where you can check out a pull request without needing to add a remote.
It is possible to do this now (link)
Suppose you have received a pull request in yourrepo from otheruser.
Add the other user as a remote
git remote add otheruser https://github.com/otheruser/yourrepo.git
Fetch
git fetch otheruser
Create a branch from their repo
git checkout -b otheruser-master otheruser/master
Now make some changes and commit. Push to their repo
git push otheruser HEAD:master
Not unless barryceelen gives you push access to his fork. You'll have to close his pull request and open a new one from your branch that includes his commits.
Not being able to do what you want to do is annoying. To make better use of GitHub flow, I'd suggest asking forkers to open issues separately from their pull requests that solve them, meaning you can keep the initial conversation flow and have it closed by whatever pull request you decide as the best.
