Branching and Merging

Git history is similar to code in that it is written once but it is read dozens of times. Therefore we optimize for readability. It should be clear what happened, by whom, when, and ideally why.

Start all work in a new branch off of master

git fetch
git checkout -b new_branch origin/master

Rebase onto master daily

This reduces merge conflicts in the future

git fetch
git rebase origin/master

Clean up your commits before creating a PR

When working locally, do whatever you want. Before sharing, clean up your history into logical commits and write good commit messages for them. Focus on clarity for someone reading this 3 months from now.

git fetch
git rebase -i origin/master
git push -u origin your_branch_name

Tip: make lots of small commits, then squash them into one or several bigger commits before pushing. This helps organize your work, so that logically separate changes can be placed into separate commits without manually splitting an existing commit

Rebase and non-ff-merge into master when you're done

git fetch
git rebase origin/master
git checkout master
git pull
git merge --no-ff your_branch_name
