Check that the ETag value is nonempty

Possible to make it send me workflow failure notification daily? lol

It seems so: https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/monitoring-workflows/notifications-for-workflow-runs

The thing is, okay now it doesn't create a PR, but it was working before and now it is not. This is unsatisfying because we do not know why or what changed. On my local system it fails when the .github/etags directory does not exist and succeeds when it does, even when that directory is empty and even, like here, when not using a GitHub PAT. But this repo does have that directory, and it is even populated with etag files.

If you want, and if you have GitHub Actions enabled for branches, you could create a debug branch and modify the workflow file to add some echos for debugging output and change --silent to --verbose in the curl command. Hopefully, that would supply some more information.

The truth is, these particular files are only to configure the Actionlint linter and are not expected to change often. But it remains unsatisfying that the workflow no longer works.

On my local system, I discovered an interesting data point. The ETag file alternates between populated and empty. I do not yet understand why or how to deal with it. This was supposed to be fixed in curl 7.70.0. The macos-14 GitHub runner is using Curl 8.7.1 (updated three weeks ago from 8.6.0). Any thoughts?

There is a workaround mentioned in a comment. But it did not work in my testing:

# mkdir -p ".github/etags"; curl --fail --silent --show-error --location --retry 3 --retry-all-errors --remove-on-error --etag-compare ".github/etags/etag.txt" --etag-save ".github/etags/etag.tmp" --remote-name --clobber --output-dir ".github/workflows" --create-dirs --url "https://raw.githubusercontent.com/Homebrew/homebrew-core/master/.github/workflows/actionlint.yml"; /bin/mv ".github/etags/etag.tmp" ".github/etags/etag.txt"; ls .github/etags/etag.txt .github/workflows/actionlint.yml;

So unless you have any ideas how to deal with this, it might be best to remove the --etag-compare and --etag-save parts of the curl command until it is fixed upstream.

Alternatively, running curl twice: the first time with --etag-save and the second time with --etag-compare does work. It exhibits the alternating empty file behavior only when those two options are provided in the same command line (which is supposed to work but doesn't seem to).

I still do not understand why it worked before and stopped working two weeks ago...
