Branching a trunk permanently

I am wondering how someone else would achieve what I am trying to do here. Basically I have a development trunk for Project A. It is updated with new code on a daily basis and has frequent branches and merges for various features etc..


I have taken a project trunk and created a completely new project from it. I am doing this because the new trunk will go off it’s own development path and I don’t want modifications on Project B to create problems in Project A. In addition, namespaces in Project B will be different. This part is no problem. The problem I have is how to effeciently transmit updates to code from one project to the other. From time to time there may be new features added that I want to add to one project or the other but not all the time.


I thought about using patches and haven’t thought about it much recently. I’m at the point now where Project A has quite a few features that I wish to add to Project B without having to copy and paste code although this is what I may have to resort too.


I guess the bottom line is, there feels like there is an easier way to do this, if there is I haven’t found it yet =)

    In these situations where you really are working with 2 different projects, I would try to “harvest” out those “features”, if possible, into their own assembly and share it across projects. I’m a firm believer that a Project (as in usually one or a few solutions, not VS Projects) should be careful about what code it “owns/trusts”, at least in the form of code. Anything that is not “owned” by my current Project, I treat as a 3rd party library (trunk\lib).

    As most of us know by now, one of the best ways to make reusability achievable is to extract out features/frameworks from existing *working* applications.

    I’m sure there are other (probably better) ways for dealing with this, but this is how I’ve usually approached it.

    I see Joe. Good advice.

    I’m going to take another look at the code base since it’s been a week or two since I’ve worked with it and see really how out of date it is.

    thanks!
