Software Development
Pull Request
Definition
A pull request (PR) is a mechanism in version control systems (like Git) for a developer to notify team members that they have completed a feature. It lets everyone involved know that they need to review the code and merge it into the main branch.
Why It Matters
Pull requests are the focal point for collaboration in modern software development. They are the venue where code reviews happen, automated checks are run, and discussions about code changes take place.
Contextual Example
After completing a feature on a Git branch named `new-login-flow`, a developer opens a pull request to merge their branch into the `main` branch. This kicks off the CI pipeline and notifies the rest of the team to review the changes.
Common Misunderstandings
- The term "Pull Request" is used by GitHub, Bitbucket, and others. GitLab uses the term "Merge Request" for the same concept.
- A PR is a request to "pull" my changes into your branch.
