Branching model

Forking workflow

Git is very flexible in organizing a distributed development team. We use a so called Forking workflow.

The following explanation is taken from an in-depth article on that model:

Instead of using a single server-side repository to act as the central codebase, it gives every developer a server-side repository. This means that each contributor has not one, but two Git repositories: a private local one and a public server-side one.

The main advantage of the Forking Workflow is that contributions can be integrated without the need for everybody to push to a single central repository. Developers push to their own server-side repositories, and only the project maintainer can push to the official repository. This allows the maintainer to accept commits from any developer without giving them write access to the official codebase.

The result is a distributed workflow that provides a flexible way for large, organic teams (including untrusted third-parties) to collaborate securely. This also makes it an ideal workflow for open source projects.!workflow-forking

The workflow is summarized in the following image from the GitHub blog:

You always fetch changes from official repository (called upstream), develop on your local repository and push changes to your server-side repository (called origin).

First thing to do when you start working on your local repository is to create a topic branch (based on the current master branch of the official repository) specific to a well defined feature or bugfix you are about to implement. Never work on the master-branch (it is reserved for the official version)! See also this tutorial on branching.

Start committing changes in logical chunks. After you are happy with your implementation push your topic branch to your forked repository on GitHub.

Open a Pull Request which will initiate the code review process.
