Chapter 3. Branching Strategies
In version control, a branch is a way to separate parallel thinking about how a piece of code might evolve. A branch always begins from a specific point in the code base. In Chapter 2 we talked about forking and cloning a repository. A branch is like an in-repository split where new work begins. A branch might be created with the intention of contributing work back, or it might be created with the intention of keeping work separate. Branches don’t care what changes they’re tracking! They just are.
The branching strategy that you use depends on your release management process. Branches allow you to change the files that are visible in the working directory for your project, and only one branch can be active at a time. Most branching strategies separate the work in your project by coarse ideas. An idea could be the version of your software—for example, version 1, version 2, version 3. And spawning from those software versions you might have ideas that are in progress. These ideas are generally separated into branches according to the name of the feature they represent. They might be a bug fix or a new feature, but they also represent whole ideas on a smaller scale.
