Pull Requests

Once you’ve commited your changes, please update your local master branch and rebase your bugfix/feature branch against it before submitting a PR.

git checkout master
git pull upstream HEAD

git checkout bugfix/notifications
git rebase master

Once you’ve resolved any conflicts, push the branch to your remote repository. It might be necessary to force push after rebasing - use with care!

New branch:

git push --set-upstream origin bugfix/notifications

Existing branch:

git push -f origin bugfix/notifications

You can now either use the hub CLI tool to create a PR, or nagivate to your GitHub repository and create a PR there.

The pull request should again contain a telling subject and a reference with fixes to an existing issue id if any. That allows developers to automatically resolve the issues once your PR gets merged.

hub pull-request

<a telling subject>

fixes #1234

Thanks a lot for your contribution!

Rebase a Branch

If you accidentally sent in a PR which was not rebased against the upstream master, developers might ask you to rebase your PR.

First off, fetch and pull upstream master.

git checkout master
git fetch --all
git pull upstream HEAD

Then change to your working branch and start rebasing it against master:

git checkout bugfix/notifications
git rebase master

If you are running into a conflict, rebase will stop and ask you to fix the problems.

git status

  both modified: path/to/conflict.cpp

Edit the file and search for >>>. Fix, build, test and save as needed.

Add the modified file(s) and continue rebasing.

git add path/to/conflict.cpp
git rebase --continue

Once succeeded ensure to push your changed history remotely.

git push -f origin bugfix/notifications

If you fear to break things, do the rebase in a backup branch first and later replace your current branch.

git checkout bugfix/notifications
git checkout -b bugfix/notifications-rebase

git rebase master

git branch -D bugfix/notifications
git checkout -b bugfix/notifications

git push -f origin bugfix/notifications

Squash Commits

Note:

Be careful with squashing. This might lead to non-recoverable mistakes.

This is for advanced Git users.

Say you want to squash the last 3 commits in your branch into a single one.

Start an interactive (-i) rebase from current HEAD minus three commits (HEAD~3).

git rebase -i HEAD~3

Git opens your preferred editor. pick the commit in the first line, change pick to squash on the other lines.

pick e4bf04e47 Fix notifications
squash d7b939d99 Tests
squash b37fd5377 Doc updates

Save and let rebase to its job. Then force push the changes to the remote origin.

git push -f origin bugfix/notifications
