Action fails to upload when using pull_request_target on GitHub

The addition of pull_request_target events allows PRs from forked repos coming into the head repo to utilize some functions that pull_request alone cannot do if PR is coming from a forked repo.

With that in mind the action always fail because GITHUB_REF is the PR Base Branch path (refs/heads/branch name). Is there a way this can be fixed through actions to detect the PR number that actions is running that will also allow usage of pull_request_target?

For the time being I am manually using the bash uploader but manually parsing through the event and extracting the PR number, which I then force the uploader to use it via -P. While this works, there’s nothing shown on that Pull Request from CodeCov unfortunately.

Took a bit of trial and error, but this step seems to work:

      - name: Publish Code Coverage
        uses: codecov/codecov-action@v1
        if: github.event_name == 'pull_request_target'
        with:
          override_pr: ${{ github.event.number }}
          override_sha: ${{ github.event.pull_request.head.sha }}
          files: ./coverage/clover.xml
          flags: tests
          fail_ci_if_error: true

I think I still need the workaround, I just don’t need the fetch-depth. Doing this worked for me:

- name: Upload Codecov report (pull_request)
  if: startsWith(github.event_name, 'pull_request')
  uses: codecov/codecov-action@v1.3.1
  with:
   directory: .
   override_pr: ${{ github.event.number }}
   override_commit: ${{ github.event.pull_request.head.sha }}
