KISS-077 "Pull Request" is a mechanism used in version control systems, specifically in platforms like GitHub, GitLab, and Azure DevOps, to propose changes to the main codebase. The process typically involves creating a copy of the main codebase (called a "fork"), making changes in that copy, and then submitting a pull request to merge those changes back into the main codebase. Here are the main components and steps involved in this process: 1. **Forking**: A developer starts by "forking" the main repository. This creates a separate copy of the repository in their own GitHub account. Forking is essential for allowing the developer to make changes without directly affecting the main project. 2. **Branching**: Within the forked repository, the developer creates a "branch". This is a separate path of development intended to encapsulate a specific feature or fix. Branching is crucial for managing different features and fixes in isolation. 3. **Committing**: The developer makes changes to the code within the branch. Each time they complete a logical block of work, they "commit" these changes to the branch. Commits are documented with a message describing the change, which is essential for tracking what was done and why. 4. **Pushing**: Once the changes are committed, the developer "pushes" these changes to the forked repository. This step ensures that the changes are reflected on GitHub, beyond the local computer. 5. **Requesting**: The developer then creates a "pull request" in the main repository. This is an official request for the maintainers of the main repository to consider merging these changes into their codebase. It includes a description of what was done and often any associated reasoning or additional details. 6. **Reviewing**: The pull request is reviewed by other developers or maintainers. They might offer feedback, ask for clarifications, or suggest improvements. The submitter of the pull request may need to make additional commits to address these issues. 7. **Merging**: If the changes are accepted, they are "merged" into the main repository. This means the changes are officially integrated into the project's codebase. 8. **Closing**: The pull request is then closed, marking the completion of the process. This process is crucial for maintaining code quality and ensuring that changes are reviewed and accepted before being introduced to the main codebase. It also serves as a communication tool among team members, documenting what was changed and why. ### Pull Request Process Creating a pull request involves creating a branch, committing changes, and submitting a pull request for review. Here are the key steps: 1. **Branching**: Create a branch for your feature or bugfix. 2. **Committing**: Commit your changes to the branch. 3. **Pushing**: Push the branch to the forked repository. 4. **Requesting**: Create a pull request in the main repository. 5. **Reviewing**: Address any feedback and make additional commits. 6. **Merging**: Once approved, merge the pull request. 7. **Closing**: Close the pull request. In summary, pull requests are a vital tool for maintaining code quality and facilitating communication in software development teams.
