Learning Gerrit Code Review

By: Luca Milanesio

Overview of this book

<p>Developing software is now more than ever before a globally distributed activity: agile methodologies that worked well enough with co-located teams now need to be empowered with additional tools such as Gerrit code review to allow the developers to share, discuss, and cooperate in a more social way, even with GitHub.</p> <p>Learning Gerrit Code Review is a practical guide that provides you with step-by-step instructions for the installation, configuration, and use of Gerrit code review. Using this book speeds up your adoption of Gerrit through the use of a unique, consolidated set of recipes ready to be used for LDAP authentication and to integrate Gerrit with Jenkins and GitHub.</p> <p>Learning Gerrit Code Review looks at the workflow benefits of code review in an agile development team, breaks it down into simple steps, and puts it into action without any hassle. It will guide you through the installation steps of Gerrit by showing you the most typical setup and configuration schemes used in private networks.</p> <p>You will also learn how to effectively use Gerrit with GitHub in order to provide the ability to add more consistent code review functionality to the social collaboration tools provided by the GitHub platform. Using the two tools together, you will be able to reuse your existing accounts and integrate your GitHub community into the development lifecycle while keeping in touch with external contributors.</p>

Understanding the Gerrit permission scheme


Git does not enforce any permission or control over the operations performed on the repository, which could be acceptable when managing a local individual clone but it is definitely not enough when sharing server repository with multiple people. The ability of Gerrit to define and enforce access controls makes it a perfect solution, even for just serving a Git repository with associated permissions.

Although permission gives you the ability to allow or deny someone access to perform one or more actions on one or more resources, not all Gerrit permissions are about enforcing security; some of them are meant to drive and organize the Code Review flow across all different roles involved.

A permission is a pyramid composed of:

  • Subject: Single or multiple sets of people identified by Gerrit.

  • Action: The ability to allow or deny a specific operation.

  • Resource: Single or multiple sets of Gerrit objects (typically Git reference) that are controlled by the...
