Thanks a lot! Looks good at a first glance. Could you add some simple tests for this? You could copy one of the existing ones, just add more than 1 file to it.

[alehed]

Sure, I just thought the test suite is ignored on this project.

[pietbrauer]

I look at it. We "just" have one failing test on macOS which is consistent 😆. iOS is a different story.

[alehed]

Yeah, would be great if all the tests worked... But I do too see the value in testing.

I'll probably get around to the tests this weekend.

[pietbrauer]

Yeah, many people have spent many hours trying to fix the tests. Thanks a lot! No pressure from my side 😅

#599 has a green iOS build, but it is already 5 months old.

Let's see what https://travis-ci.org/libgit2/objective-git/builds/237270148 brings.

Turns out it wasn't that hard. #631 has a green build. Thanks for pushing this @alehed!

[alehed]

@pietbrauer Thanks for fixing the build! 👍

[alehed]

I added a small test.
