[BUG]: Fetch a given reference uses the wrong API about octokit.rb

[nickfloyd]

Hey @kitallis thank you for bringing this up. This particular API set is confusing.

So we have all of the GitHub REST API set for references - breaking them down below quickly for clarity - It looks like we have a couple of problems.

All this to say, thank you for being open to get this sorted, please feel free to do so! ❤️ Also, even though this is wrong I'm feeling like it will be a breaking change - we'll version as such so that anyone using these SDKs will have a heads up on the change.

Here are the details. Please feel free to correct both implementations if you have time. Head's up on the cassette, they might need to be regenerated.

• List matching refs: https://api.github.com/repos/OWNER/REPO/git/matching-refs/REF (supports tag or branch names)
  • ❌ implemented here - Incorrectly ("When you use this endpoint without providing a :ref, it will return an array of all the references from your Git database, including notes and stashes if they exist on the server.")
  • documented here
• List all matching references: https://api.github.com/repos/OWNER/REPO/git/matching-refs
  • ✅ implemented here
  • documented here
• Get a reference: https://api.github.com/repos/OWNER/REPO/git/ref/REF (supports tag or branch names)
  • ❌ implemented here - incorrectly (as you pointed out, should be .../ref/:ref)
  • documented here
• Create | Update | Delete references all use: HTTP verb + https://api.github.com/repos/OWNER/REPO/git/refs/REF
  • ✅ implemented here
  • documented here

Thank you again for helping to make our community better!

Thanks @nickfloyd.

I had to squint to understand why you pointed out the "List matching refs" to be an incorrect implementation. Just adding some more info here for clarity:

List matching refs is actually just one API. Documented here.

This API also claims in the docs, that the ref is a required field. While simultaneously saying the bit about When you use this endpoint without providing a :ref... etc. Which means it's technically not a required field?

This perhaps means that the octokit interface should either optionally take a ref or implement the two ways as different methods. I will give a shot at "Get a reference" over the weekend since that's my current need. If the others are equally simple to change, I can correct them as well.

This is still on my radar. I will come back to it soon.

Hey @kitallis thanks for the follow up here.

I'll leave the implementation in your capable hands! Either implement as an optional parameter or as an overload with different signatures (as two separate methods). My gut would favor being more explicit and having two methods but SDKs are meant to abstract out complexity and expressiveness so that consumers don't have to know the implementation details of a given API - in this case I feel like both options that you present still serve the SDK philosophy well.

I'm looking forward to seeing what you come up with! As always thank you for being a member of this community and working to make things better for everyone ❤️ !
