Gerrit (software)

Gerrit is a free and open-source code review system. It is based on the Git version control system and provides a web-based interface for developers to review and manage changes before they are integrated into a project. It is commonly used in collaborative software development environments to ensure code quality and maintain a clear history of changes.

Gerrit uses a distributed workflow, meaning developers work locally on their changes and then upload them to Gerrit for review. Reviewers can then comment on the changes, suggest modifications, and ultimately approve or reject them. This process ensures that multiple eyes are on the code before it merges into the main branch, reducing the chances of bugs and improving overall code quality.

Key features of Gerrit include:

• Code Review: A central feature, providing a structured process for reviewing patches. This involves comments, annotations, and a voting system for approval.
• Access Control: Provides granular control over who can access and modify different parts of the project's code. This contributes to security and project governance.
• Change Tracking: Maintains a detailed history of all changes submitted, reviewed, and merged. This provides transparency and allows for easy tracking of modifications.
• Integration with Git: Seamlessly integrates with Git, allowing developers to use their familiar workflow.
• Web Interface: Offers a user-friendly web interface for managing code reviews, changes, and project administration.
• Extensibility: Through plugins, Gerrit's functionality can be extended to suit various project needs.

Gerrit is often integrated into Continuous Integration/Continuous Delivery (CI/CD) pipelines, allowing for automated testing and deployment once code is approved. Its structured review process enhances collaboration and facilitates efficient software development. The system encourages discussion and provides a clear audit trail, making it a valuable tool for software development teams of all sizes.
