I was introduced a while ago to the "git cvsexportcommit" command, which effectively allows me to work exclusively in git, thanks to our git mirror. The only downsides at, the moment, are: The git mirror is only updated every 30mins, and I need to do a CVS update before I push a commit from git to CVS. On the other hand of the equation, we have a number of hurdles to face before a conversion can be started, and the problem is that the hurdles are not all just technical (multiple projects sharing portions of the same repository), but human as well (convincing people to change). So the balance of benefits versus effort made me give up a bit on the idea, at least for now. For now, in order for this to happen, we would have to change something in the way we either get the sources, or in the way we build, or both. We might also not be able to do the transition just on our own, and that means coordination with other projects, etc. Perhaps, as more git features appear, we might be able to find a simpler way to transition, and that could be the trigger for transition to really start... One of the things that we could think about, is getting away from our 'partial checkout' way of getting the sources. It's convenient, but it is also makes us utterly dependent on CVS. I think there is a simple solution to that: (1) Separate out the projects that could go on to live their lives on their own (Eg: expect, tcl, tck, winsup, rda, etc) (2) And for the remaining projects, either: (a) Share one large repository: We would have to change the way we configure or the "make" command we use to build; (b) Have our own set of sources, with synchronization issues (which if effectively the same as (1), really). Option (1) is not strictly necessary for option (2a), but I think it would be a good cleanup, and probably benficial to those projects too - as they would be getting more freedom, I think. I just realized for instance that dejagnu is no longer part of src/. It's under git, now. The problem is that you have to convince people that all these changes are desirable, and that, I think, is more difficult than the technical work itself... -- Joel
