Does not respect default branch of fork

[timwis]

Hi team, we make use of this plugin in JKAN, a Jekyll-powered open data catalog. I've noticed that this plugin seems to use the default branch of the upstream repository, rather than the fork.

The only property made available is site.github.source.branch, which refers to upstream. In addition, github_edit_link uses the upstream branch in the URL it generates.

The issue with this—apart from it being different than what I assume people would expect—is that if someone forks JKAN and, say, switches to the new GitHub Actions based workflow for publishing GitHub Pages, then updates their default branch to main since they're not using the gh-pages workflow anymore, the links on the page will stop working. Another instance might be a case where an upstream repo uses master as the default branch, and the fork changes it to main.

I'm a bit surprised this hasn't come up before—to the point that I'm wondering if I'm missing something. Is there a reason it's like this?

Looking at the GitHub API, the source property does appear to refer to the upstream repo in the case of a fork, so I propose that rather than changing that property, we simply add the property default_branch from the api. I'd be happy to submit a PR to that effect, but wanted to check if it's welcome first.

Thanks all.

Hi there jekyllbot, nice to see you again. Just to confirm that yes, this is still an issue/bug.

@yoannchaudet Hi! Is this intended behavior of the source result from the GitHub API? For a forked repo, source appears to read from the upstream, rather than the forked repo. I think we use the mister-fantastic preview, but I can't remember the details of how that preview changes the API.

so I propose that rather than changing that property, we simply add the property default_branch from the api. I'd be happy to submit a PR to that effect, but wanted to check if it's welcome first.

Sounds reasonable. Feel free to ship a PR.

Hey folks, upon further investigation, I think there may actually be a bug with the GitHub API that's causing this.

repository.rb appears to call the pages resource of the github api. I tried running that manually:

curl -L \
  -H "Accept: application/vnd.github+json" \
  -H "Authorization: Bearer <YOUR-TOKEN>"\
  -H "X-GitHub-Api-Version: 2022-11-28" \
  https://api.github.com/repos/timwis/jkan/pages

and it returns:

{
  "url": "https://api.github.com/repos/timwis/jkan/pages",
  "status": "built",
  "cname": null,
  "custom_404": false,
  "html_url": "http://timwis.com/jkan/",
  "build_type": "workflow",
  "source": {
    "branch": "gh-pages",
    "path": "/"
  },
  "public": true,
  "protected_domain_state": null,
  "pending_domain_unverified_at": null,
  "https_certificate": {
    "state": "approved",
    "description": "The certificate has been approved.",
    "domains": [
      null,
      "www.timwis.com"
    ],
    "expires_at": "2023-07-05"
  },
  "https_enforced": false
}

But the branch gh-pages no longer exists on timwis/jkan.

Similarly, running the request on azavea/opendataphilly-jkan returns that the source.branch is v2, which also no longer exists on that repo.

(Note that I've tried swapping the Accept header with application/vnd.github.mister-fantastic-preview+json, and running it on timwis-test/jkan, which is a fork and does not use a custom domain)

I suspect this may have something to do with the fact that we're publishing to GitHub Pages via an Actions workflow rather than the traditional branch auto-publish, and perhaps the Pages resource of the API hasn't been updated when that feature was released?

Were you able to get an answer to your API question above? Sounds like a good question to ask Support.
