After reading the git protocol and searching on the web for a little
bit, my conclusion is that no, you cannot use “git log” without having a
clone of the repository.
Given that we are talking about repositories which do not use tags, we
could specify --depth=1 when cloning to get a shallow clone, i.e. only
the latest commit. That saves bandwidth and disk space, but has the
downside that we cannot do any additional validation, i.e. we can’t
detect if upstream ever starts using tags — unfortunately, that is a
plausible scenario, so I would suggest doing a full clone.
For GitHub, we can apply an optimization: the GitHub HTTP API exposes
repository details, such as:
1. The default_branch of the repo, in
2. The latest commit of the branch, in
For interactive use by individual developers, we could send these HTTP
requests unauthenticated. For a setup which does many uscan calls, we’d
need to create a GitHub account to get the higher rate limit. See

In a day, not in a minute. But regardless, you are probably right. I
asked in the pkg-go IRC channel to see whether people are okay with
removing that part from the version number, so barring any objections,
we can probably get that done within the next few days.

Agreed — if we get rid of the number of commits, we shouldn’t need git
describe, not even in dh-make-golang.
It seems like you have a good handle on implementing this in uscan. Do
you need any additional details? Do you prefer an external patch from
us over implementing this yourself? I’d be happy to give you feedback on
a proposed patch or git commit.
Thank you very much!
