Bug in Code Owners / MR Approvals widget?

Summary

I recently added a section [Docs Create] with files to this project's CODEOWNERS file so that MRs authors can easily spot who to assign for review.

  • Problem 1: The MR Approvals widget shows the new [Docs Create] section but doesn't show who owns the file.
  • Problem 2: Code Owners is considering the group who owns /doc/ instead of considering the owner to the file /doc/user/project/merge_requests/merge_request_approvals.md. It's my understanding that the last rule listed prevails. Is this correct?

What we have in the CODEOWNERS file:

Screen_Shot_2020-08-18_at_13.09.10

What we have in the widget:

Screen_Shot_2020-08-18_at_13.12.21

Shouldn't it only show the last rule? 🤔 Which is:

/doc/user/project/merge_requests/merge_request_approvals.md @marcia => therefore, the widget should show only my username instead of the whole group for doc/, no? That's how it works for /doc/development/, for example.

Oh! Wait a min! Maybe the reason is that I'm the MR author (!39701 (merged)), therefore, I'm not an eligible approver. In that case, I guess we should hide the "Docs Create" section?

Steps to reproduce

  1. Add a dir to a CODEOWNERS section with a group as owner to the dir.
  2. Below the dir, add a new section with a file that belongs to this dir and a user as owner to the file.
  3. Change the file and submit a merge request.
  4. Open the MR Approvals widget to see who owns the file.

Example Project

https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/CODEOWNERS#L29 // !39701 (merged)

What is the current bug behavior?

  • Code Owners considers the group set as owner to a high-level dir as code owner instead of a user set as owner to a file within the folder.
  • Doesn't display the avatar of the file's code owner, only the Code Owner's section ("Docs Create") and the file name.

What is the expected correct behavior?

  • Consider the last rule and only show the code owner to that file.
  • Show the user's avatar.
