A guide for programming within version control.
- Avoid including files in source control that are specific to your development machine or process.
- Delete local and remote feature branches after merging.
- Perform work in a feature branch.
- Rebase frequently to incorporate upstream changes.
- Use a pull request for code reviews.
Create a local feature branch based off master.
git checkout master git pull git checkout -b <branch-name>
Rebase frequently to incorporate upstream changes.
git fetch origin git rebase origin/master
Resolve conflicts. When feature is complete and tests pass, stage the changes.
git add --all
When you’ve staged the changes, commit them.
git status git commit --verbose
Write a good commit message. Example format:
Present-tense summary under 50 characters * More information about commit (under 72 characters). * More information about commit (under 72 characters). http://project.management-system.com/ticket/123
If you’ve created more than one commit, use a rebase to squash them into cohesive commits with good messages:
git rebase -i origin/master
Share your branch.
git push origin <branch-name>
Submit a GitHub pull request.
Ask for a code review in the project’s chat room.
A team member other than the author reviews the pull request. They follow Code Review guidelines to avoid miscommunication.
They make comments and ask questions directly on lines of code in the GitHub web interface or in the project’s chat room.
For changes which they can make themselves, they check out the branch.
git checkout <branch-name> ./bin/setup git diff staging/master..HEAD
They make small changes right in the branch, test the feature on their machine, run tests, commit, and push.
When satisfied, they comment on the pull request
Ready to merge.
Rebase interactively. Squash commits like “Fix whitespace” into one or a small number of valuable commit(s). Edit commit messages to reveal intent. Run tests.
git fetch origin git rebase -i origin/master
Force push your branch. This allows GitHub to automatically close your pull request and mark it as merged when your commit(s) are pushed to master. It also makes it possible to find the pull request that brought in your changes.
git push --force origin <branch-name>
View a list of new commits. View changed files. Merge branch into master.
git log origin/master..<branch-name> git diff --stat origin/master git checkout master git merge <branch-name> --ff-only git push
Delete your remote feature branch.
git push origin --delete <branch-name>
Delete your local feature branch.
git branch --delete <branch-name>
