The basic workflow would be a push without a rebase. In the event that a new revision comes back when you look for the revision you just pushed, those new revision(s) would be committed on top of their correct parent revs and then a dummy merge would be created whose tree state was exactly the data pulled from subversion for the pushed rev. That's probably confusing. If it is, ask and I'll try to diagram it out.

You're right, it is confusing, but then again I'm new to DVCS. Is the approach you described above used by git-svn as well? I guess what I'd like to know is if git-svn model is more suitable for svn bridging. In the long run I'd like to convert the natives to a native Mercurial setup, mainly because of the ease of distributed cross-platform use. -- -- You received this message because you are subscribed to the Google Groups "hgsubversion" group.
