You probably haven't, because I invented it. Just like in a two-way street cars can go on both directions, in a two-way branch you push and pull from the same destination. > > > [RK] Merges are infrequent, but because we are working in different areas, > > we merge to "our own" branch (few conflicts, usually) and push to its > > remote. > > > > This is crucial. > > Is it ? > > > Is the local and remote branch always the same? > > Yes. > > > In other words: do you always pull from "origin/topic", and push to "topic"? > > Yes.

Before that we were on CVS (actually CVSNT). Those are centralized, with merging and branches allowed, but not different repos. > Originally all the work produced a single final product installer.

Does that make it #3? Yes, you sometimes use a triangular workflow: pull from your branch, push to his branch. Even though it's on the same repository. Either way, you probably always configure the upstream branch to be your branch, so you always know what your local "topic" points to on the remote. -- Felipe Contreras
