Allow comparing Branch objects#1234
Conversation
Add implementations for `PartialOrd`, `Ord`, `PartialEq`, and `Eq`. The actual is delegated to the underlying `Reference` object. Closes rust-lang#422

Haven't yet checked by myself. Does libgit2 have or plan to have an compare functions for branch or references?

It allows comparing references with git_reference_cmp() which is what impl<'repo> Ord for Reference<'repo> uses
| let mut b1 = repo.branch("foo", &commit, false).unwrap(); | ||
| assert!(!b1.is_head()); | ||
| repo.branch("foo2", &commit, false).unwrap(); | ||
| let b2 = repo.branch("foo2", &commit, false).unwrap(); |

Have we considered the equality here be based on branch name instead of Reference equality? It is a bit weird and too implicit when two different branch names differ comparsion says there are the same.
Perhaps we should be more explicit on the comparsion, and don't implement the eq operator?

What if you had two different references (lowercase) to the same branch, but the underlying References are not the same - I would be surprised if those two branches are considered equal

Agree with that one, too.
Semantically a reference is composed of target and name and oid. However upstream libgit2 has a bug that didn't consider them when comparing. They fixed that in libgit2/libgit2#6346 but won't release it until libgit2 v2.
I think until then we might not want to tie to one about-to-change semantic. What do you think?
(#851 has done a good research btw)

No objections to waiting, but do we know when libgit2 v2 will come out?

I have no idea to be honest. See
