That's not exactly true. You can't be as efficient with dumb protocols than you are with a dedicated protocol (something with some intelligence on both sides), but at least the second point you mention can be achieved with a dumb protocol, and bzr is a proof of existance. To read over HTTP, it uses ranges request, and to push over ftp/sftp/webdav, it appends new data to existing files (its ancestor, GNU Arch, also had a way to be network-efficient on dumb protocols). Regarding atomic and lock-less updates, I believe this is implementable too as soon as you have an atomit "rename" in the protocol. But here, bzr isn't a proof of existance, it does locking. (BTW, about bzr, it also has a dedicated server now) -- Matthieu - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
