Branching as a Coping Mechanism
Branching is a coping mechanism. There is a lot of branching and release-time cherry-picking of features in the commercial software world. It seems to alleviate some pain and make the process more manageable, but I fear this is at too great a cost. Many development groups branch due to dysfunction. Note that I am not talking about open source projects. I'm specifically speaking about commercial projects where programming talent is not free. I'm also not talking down distributed version control, where every checkout is really a separate branch. I am concerned more about use of branches for the wrong reasons and at a high cost. Often branching is used to put off integration. This is a losing game. After so many changes to the trunk a branch will no longer slide seamlessly into the release stream. We can work around that problem (itself a work-around) if we merge forward all branches periodically so that they track the trunk more closely. This activity is time spent on featu...
