You can make such revision switches a natural part of commits. "git submodule update [--recursive]" will bring your submodule checkouts in sync with what the toplevel repository expects. In any way we can have this discussion separate from the discussion of moving to git. We can stay with our current ways of matching same date for now. - Matthias

No date > matching and the like is necessary with subversion.True to some extend, though I know several people (myself included) that rather use the git-svn inconvenience today simply because git-bisect exists and git being a lot faster at switching revisions than subversion. This tactic also starts failing once you work with custom release branches outside of llvm.org's control. In principle you could also put the toplevel llvm svn into a git-svn repository to fix the problems and I think there is some repository out there who does that, but IMO that just brings back part of the problem of slow checkouts (a few gigabytes of extra disk space required per checkout as well). - Matthias -------------- next part -------------- An HTML attachment was scrubbed...
