As a newbie to the CPython repository, it can be quite frustrating to find issues that have not an associated pull request.

Thelinked:pr has a small coverage and requires manual intervention (ie. a "closes" or "fixes" magic keyword in the description). Moreover, the linked:pr will close the associated issue on merge, and sometimes the issue should be kept open (because of retrocompatibility PRs, and others that I can not yet grasp).

The GitHub API exposes another concept (cross references) and these appear in the history of an issue. This is why I first implemented a script to list all the issues and the associated PRs. The output lookslike this. But this is not a scalable solution: the GitHub API could suffer if all the newbies were to use it, and the script needs to be executed often to keep the picture up to date with reality.

Given that the cross-references are essentially events, why don't we add a github workflow that

• adds ahas-pr label when a PR is created, referencing an issue in its title or in its description
• adds ahas-pr label when a comment is added to the PR mentioning an issue
• removes thehas-pr label when the PR is closed without being merged

I have a sample GitHub Actions workflow available on thenilleb/cpython-stub repository
