Gerrit is a web-based, team-centric code review tool for projects using the Git version control system. It's designed to help software development teams examine changes being made to their codebase, serving as a crucial step in creating high-quality, stable code. Today, we're exploring Gerrit's features, best practices, and how it integrates with GitLab.
Before diving into Gerrit's prowess, let's briefly understand why code review is essential. Thorough code review ensures code quality, improves knowledge sharing, and fosters a collaborative work environment among developers. It's an opportunity to learn from others and make contributions more meaningful.
Gerrit's Notable Features
Gerrit brings several intuitive features to streamline the code review process.
Web-based Interface
Gerrit's user-friendly, web-based interface allows developers to manage code reviews directly from their web browsers, enhancing accessibility and collaboration.
With the web interface, developers can create, view, and edit change lists, incorporate reviews, and perform patch sets all within a few clicks.

Git Integration
Gerrit is built specifically for Git, ensuring seamless integration between the two. It supports Git's workflow perfectly, enabling developers to push changes and submit them for review effortlessly.
Moreover, Gerrit can track and integrate changes from multiple branches, simplifying the development process and minimizing conflicts.
Gerrit Workflow: A Deep Dive
Understanding Gerrit's workflow is crucial for efficient code reviews. Here's a step-by-step walkthrough:
Submitting a Change
Developers push their changes to the Gerrit Git repository, automatically creating a code review. The change list includes essential details like the project, branch, and a summary of changes.
After submitting, the developer typically addresses review feedback by amending the change, incrementing the patch set number. If the review is positive, the change can be submitted, applying the changes to the project.
Reviewing Changes
Once a change is submitted, developers can review it by providing comments or votes. The review process encompasses several steps:
- Commenting on specific lines with suggestions, questions, or approvals.
- Voting on the change with +1 (approved), -1 (rejected), or 0 (abstain).
- Providing an overall assessment, specifying if the change needs more work or can be merged.
Integrating Gerrit with GitLab
While GitLab offers built-in code review features, integrating Gerrit can bring additional benefits. GitLab CE/EE supports Gerrit, enabling developers to utilize Gerrit's code review functionalities directly from GitLab.
Setting up the Integration
To integrate Gerrit with GitLab, you'll need to configure Gerrit to use GitLab's OMGSAP protocol, and next, configure GitLab for Gerrit integration. Once set up, developers can:
- Push changes for review directly from GitLab.
- Access Gerrit's code review interface directly from GitLab.
- Vote and comment on changes from within GitLab.
Benefits of the Integration
Combining Gerrit's robust code review capabilities with GitLab's comprehensive CI/CD and issue tracking offers developers a unified platform for managing software development.
Developers can leverage GitLab's CI/CD pipelines to automate code review processes, while Gerrit's web-based interface simplifies collaboration and communication during code reviews.
In conclusion, Gerrit's powerful, user-friendly features make it an invaluable tool for managing code reviews. Its seamless Git integration and compatibility with GitLab further extend its appeal, fostering a collaborative, efficient development environment. Consider adopting Gerrit in your workflow to elevate your team's code review processes.
