# Please see https://github.com/NixOS/nix/issues/13457
# for a higher description of the purpose of the test.
# tl;dr;fetchGit will utilize the git cache and avoid refetching when possible.
# It relies on the presence of either the commit when rev is provided
# or checks if the ref refs/heads/<ref_name> if ref is provided.
#
# Unfortunately, git can occasionally "pack references" which moves the references
# from individual files to a single unifies file.
# When this occurs, nix can no longer check for the presence of the ref to check
# for the mtime and will refetch unnecessarily.
