PyPI now supports digital attestations

I have a bit of uneasiness about how this is heavily pushing GitHub actions as the correct way to publish to PyPI. I had to check PEP740 to make sure it was not directly supported by Microsoft.

> The generation and publication of attestations happens by default, and no changes are necessary for projects that meet all of these conditions: publish from GitHub Actions; via Trusted Publishing; and use the pypa/gh-action-pypi-publish action to publish.

If you then click on "The manual way" it adds a big disclaimer:

> STOP! You probably don't need this section; it exists only to provide some internal details about how attestation generation and uploading work. If you're an ordinary user, it is strongly recommended that you use one of the official workflows described above.

Where the only official workflow is "Use GitHub Actions".

I guess I am an idealist but as a maintainer this falls short of my expectations for the openness of Python and PyPI.

> Where the only official workflow is "Use GitHub Actions".

The standard behind this (PEP 740) supports anything that can be used with Trusted Publishing[1]. That includes GitLab, Google Cloud, ActiveState, and can include any other OIDC IdP if people make a good case for including it.

It's not tied to Microsoft or GitHub in any particular way. The only reason it emphasizes GitHub Actions is because that's where the overwhelming majority of automatic publishing traffic comes from, and because it follows a similar enablement pattern as Trusted Publishing did (where we did GitHub first, followed by GitLab and other providers).

I get that, that's why I didn't go "This is Embrace Extend Extinguish", but as constructive feedback I would recommend softening the language and to replace:

> STOP! You probably don't need this section;

In https://docs.pypi.org/attestations/producing-attestations/#t...

Perhaps also add a few of the providers you listed as well?

> The only reason it emphasizes GitHub Actions is because that's where the overwhelming majority of automatic publishing traffic comes from

GitHub being popular is a self-reinforcing process, if GitHub is your first class citizen for something as crucial as trusted publishing then projects on GitHub will see a higher adoption and become the de-facto "secure choice".

PyPI should support and encourage open infrastructure.

If I don't want to use GitHub, let alone GitHub Actions, I am now effectively excluded from publishing my work on PyPI: quite unacceptable.

That’s now how any of this works. I am begging you to re-read the docs and understand that this does not require anybody to use GitHub, much less GitHub Actions, much less Trusted Publishing, much less attestations.

You can still, and will always be able to use API tokens.

Thank you for being patient with people that seem to have willfully not read any of the docs or your clarifying comments here, are saying you are lying, and/or are making up hypothetical situations. It's appreciated!

Edit: woodruffw is sitting here and thoughtfully commenting and answering people despite how hostile some of the comments are (someone even said "This is probably deserving a criminal investigation"! and it has more upvotes than this comment). I think that should be appreciated, even if you don't like Python.

I know attestations are not mandatory, but the rug has already been pulled: PEP 740 distinguishes "good" and "bad" packages and "good" packages require GitHub.

Attestations are worthless unless they're checked. I have no doubt they'll eventually become the default in pip which effectively makes them mandatory for 99% of people not willing to jump through the hoops of installing an unattested package.
