Source control and roaming the glens...

We use ClearCase, and each developer working on new features uses a different branch for development. This won't block others from checking out the file while you're gone, even though you have it checked out (but on a different branch). When you get back, it's a simple matter to merge things back to the mainline code after it's been tested and ready for the wild.

That statement can only be true for the most degenerate cases, where the components that the separate users are working on are completely separate and have static, well-defined interfaces to other components.

A question came up at work recently, though I've thought about before. You have a nice shiny source control system, and many happy developers at code headquarters. But you need to take your laptop and go to a customers site in the deep arctic, and internet access there is limited at best, and you can only borrow a pc to check your email. You'll be there for a few weeks, and for nothing better to do, will be writing a feature or two in the software, or may need to tweak it to match immediate customer demands. How would that work with source control? If you checked out the code, would that prevent colleagues from working on it in your absence?

Use the source controls branching feature then merge when you get back.

In our case, the developer took a copy of the working code with him on the laptop and made his changes locally. After he got back, he carefully merged his changes in with the rest of the code. He was lost in the outback of southern France for a while :rolleyes:.

SVN doesn't lock files on checkout by default, which is a good thing. Your colleagues can do all the simultaneous edits they want. It comes down to when people commit back to the repo, SVN will then check for differences between your working copy and the repo. In your situation, as Trollslayer and others said, branch. Then merge when you get back. BTW you can also contribute patches over email to SVN repos.

Another point of ignorance exposed. If I can just do a chunky checkout, then merge on return without stepping on too many toes, the problem goes away. I had understood checkout to be more of a locking activity than it apparently is! And emailling back changes could be a handy trick. Iain.

Yeah, it is a hangover from older source control systems which locked files on checkout and unlocked them on commit. SVN can be setup to work like this and other source control systems still do it (perforce for instance.) It is up to you what you prefer but you'll find most major open source projects use the "copy-modify-merge" model instead of the "lock-modify-unlock" model.

If your source control supports branches, I would create a branch off your main development branch, and create a local view of that on your laptop. You could either check out all the source files and work on them, or manually keep track of which files you've changed. Then check everything back in to your once you are back, and merge from your branch to your main branch. Generally speaking most source control systems would allow multiple checkouts, although it relies on people being smart enough to be able to merge their changes in correctly

Actually, even complex cases can be merged very easily in ClearCase. Perhaps you've not worked with ClearCase and merged such cases. It works extremely well, even if 3 or 4 people have modified the same file on different branches.

One of the earlier posters mentioned Bazaar (bzr), which sounds quite interesting. It doesn't require a server setup, so is easier to experiment with. Iain.
