Looking at the actual git_retry.py script [1], it really just wraps actual Git commands. IMO, git-retry(1) shell script as you mentioned only calls the python version, which adds another level of indirection (why not doing it in pure shell?). AFAIK, to solve the retrying problem, we need to have a way to tell transport backend (curl/ssh) to resume transfer from the faulty point. > > As regex matching might eventually break whenever `git` changes > anything in the output messages, I wondered if there could be a more > robust internal implementation in git itself?
