This was an interesting test failure. What was happening here is it accidentally working. The procedure adds two new index entries with identical OIDs. Then, when checking for the order of insertion we sorted by OID. The stability of this sort depends on too many factors, and was in fact in a different order on Windows. Quick fix is create the second index entry with an OID higher than the first.

e = IndexTest.new_index_entry
@index << e

e[:path] = "else.txt"
@index << e

f = IndexTest.new_index_entry
f[:oid].succ!
@index << f

@index.write

index2 = Rugged::Index.new(@tmpfile.path)

Making all temporary directory removal go through the same procedure for working around the open file handle issue mentioned later.

There may be some sort of difference with Windows where callbacks will not trigger unless a buffer hits a certain size. Other clone tests pass, so we know that cloning actually works, it's only the callback which doesn't trigger.

Another interesting thing I don't know how to resolve. The libgit2 test repo has modifications initially, confirmed on linux and windows. Apparently on *nix checking out another pointer isn't an issue here, on Windows it is for some reason.

# on Windows this errors with CheckoutError: 1 conflict prevents checkout

The largest issue I kept running into with these tests is something about the Windows libgit2 was leaving open file handles to the temporary directories created. It appears the handles close when the test suite finishes. Therefore I think the best thing to do is clean up everything at the end of the suite instead of inline.
