Is it possible to push a commit and not a reference in libgit2?

Question

Is it possible to push a commit and not a reference in libgit2 i.e. basically do the equivalent of git push {remote} {commit}:{branch}?

When I try to call git_remote_upload() with a refspec like e9c46cd9071113c95f6b3fb48b74f98056abf7a1:refs/heads/master, it fails with this error:

No such reference 'e9c46cd9071113c95f6b3fb48b74f98056abf7a1'

Am I doing something wrong or is this feature simply not supported?

Answer 1

Nobody who uses push has added the feature yet. The push functions expect the refspecs to use references for both sides.
