Gerrit is a collaborative review system for Git . Changes to software can be discussed with Gerrit and ultimately integrated into it.
The open source project Gerrit allows all changes to be confirmed by one or more users before they are integrated into the official source code . An automatic build process , such as that provided by Jenkins / Hudson , can also be used as support.
history
Gerrit's development began when a source code control system was needed for the development of the Android operating system . Since numerous Google developers were involved in the development of Android , this system should have a similar scope to the Mondrian review system previously used by Google . The Rietveld software was initially used for this purpose. When it became apparent that the development of this software was not going fast enough, Rietveld was forked ; Gerrit 1.0 was created. The name Gerrit is intended to remind of the Dutch architect Gerrit Rietveld .
The entire code of the fork has been rewritten for Gerrit 2.0. While Gerrit was originally programmed in Python , from version 2 it is written in Java EE ( Java Platform, Enterprise Edition , Java Servlet with SQL ).
Workflow
The Gerrit review system is used together with a Git repository .
The Git repository contains the source code of software. Changes that are to be made to this source code can generally be git pushwritten directly to the repository by users with the appropriate rights using the Git command .
Instead, a Gerrit installation can also be connected upstream in such a way that the desired changes cannot be sent directly to the repository, but instead have to be sent to the Gerrit installation. Gerrit provides a web interface where the changes can be discussed and improved versions of the changes can be uploaded. It is possible to compare changes as a diff view. Reviewers can attach their comments to specific lines and thus easily create a direct reference to a specific line of code. Every change set (called patch set) can be voted on. After a patch set has received the required votes, users who have the necessary rights can write the changes to the repository via the web interface.
