Yes. Of course. > I'd have said a repository can have many "modules" or "projects", and > each of those can have several branches. A module can hold other > modules, but from its POV also be part of a super-module (or > superproject), we just have to take care to not build loops. You cannot build a loop. OK, let me rephrase: I can build a loop where at one point in time project A uses project B as his subproject; then later I can have project B use project A as a subproject. That's a loop. But the commits themselves are not in a cycle. There is a specific version of A that requires a specific version of B, and there is a different version of B that requires an entirely different version of A. This loop really just means we have to be smart about how we switch between versions of a project. Just like if B is required in one version of superproject A and not in another; when I switch back and forth in A I expect B to appear/disappear. And I expect it to work on an airplane, where network access to reclone B is not available (or is too costly). That means we have to "hide" B when its not needed. If you can actually form a loop where version of A requires version of B and version of B requires the version of A that requires the version of B... that's a SHA-1 hash collision. If you can make them at will, you probably can make some good money illegally... > Is my view of the world correct so far?
