Currently I am working on a project that uses TFS as source control. I am in the middle of implementing a piece of functionality, but am blocked by work that needs to be done by outside resources. Since the functionality is not fully complete, I can’t check in the changes without breaking the build. So instead of waiting a couple days while the blocking work is finished, I want to work on some defects.
To do this work in isolation from my other changes, I am working the defects in a second workspace I just created.
After using a second workspace to isolate my changes, a coworker asked me why I didn’t just shelve my changes. After doing some reading on shelving, it looks like this is preferred solution to situations like mine. My question is what situations, if any, would you create multiple workspaces and what situations should you use shelving? There are some posts about shelving, but I don’t see very much on the subject of workspaces.
By the way, I got the idea for creating a second workspace here.
A new branch would probably be the best way to go. But, to answer your question, one of the key differences between shelving and just using a differnet workspace is that when you shelve, you push your code back to TFS, so it is backed up. Whatever is in your workspace is just what you have on your machine — if you lose it, it’s gone.
We use branching a lot in my shop, and as a result, I haven’t seen many uses for shelving.
However, I have found one case where it has been very useful to me:
I often bounce between 2 different development machines (one at the office, one at home, connected via VPN). If I am working on something, and I want to transfer it from home to work, or vice-versa, I often use shelving. I can shelve it from one machine and un-shelve it from the other. I do this when I am in the middle of a change, and checking in would break the build or otherwise interrupt other developers.
