This section explains the basis of branching strategies and the two main philosophies of branching. It also provides some answers to the question of when and why you should branch on a project.
Branching Philosophies
The general rule of thumb for branching is: keep the main line of development on the trunk; everything else can be branched. The problem is determining the main line of development. Should the trunk contain stable code or unstable code? Should each release be branched when it goes to be tested? Should new features be developed on the trunk or on a branch?
These decisions all stem from two distinct definitions of “the main line of development.” These two definitions result in two different branching philosophies, which can be termed basically stable and basically unstable.
Basically stable
The basically stable branching philosophy states that the trunk should contain project data that is always close to being ready for release. Branches are used for development, bug fixes, prerelease QA (quality assurance), and refactoring. Branches are also used for experimental code.
The strictest variation of this philosophy states that nothing should be merged to the trunk until it has been through QA. This ensures that at any time a release candidate can be taken from the trunk, put through a small amount of QA, and then published or sold.
More lenient variations of this philosophy allow anything that passes developer unit-testing to be merged into the trunk. Such ...
