I am a big fan of DVCS systems, so I felt the need to chime in. See below.
Hey Julio, Thanks a lot for chiming in. I found your comments very interesting (will comment directly in a minute though I don't have much to add). I do have some questions about the talk... I'm going back it and came across a section at ~45:00 where Linus mentions 'superprojects'. I'm trying to determine if this parallels the way I have been using subversion+externals. He is talking about performance and points out that, if your repository is very large, initial clone operations will be slow, since you have to download the entire history of this repository. He goes on to say that if you have a multiple components, you should put them in separate repositories. You then have a 'superproject' that contains 'pointers' to other projects. You keep separate projects separate. If you have a library, for instance, that is used by several components, you would put this in a separate repository. He mentions that the UI is still rough in this area. If you know about this stuff, could you discuss it a bit? Specificially, I'm wondering: - what does the syntax look like (just for the sake of concreteness)? - If I branch my superproject, what happens to my subprojects? anything? - If I was working on a superproject and discovered that I needed to branch four components simultaneously (e.g. they were somehow interdependent and i wanted to detangle them), how would I do it? - How widespread is the use of superprojects in the kernel.... how many projects does the toplevel superproject contain? Thanks in advance, -t
