Is there a feature request for actions/checkout to retry checkouts?

I'm unsure about using a third party action here, vs e.g. a run: block just using git commands.

We raised a support ticket with GitHub and a couple of tips have been generated. One of this was to add a retry to the checkout.

Funny enough, the retry doesn't exist on the checkout action!

I'm going to raise one

That's just the third-party linter that complaining about something that either doesn't exist or hasn't been added to the linter's schema.

Please could you rename your branch to 3.14-test-retry so it will trigger some jobs that use actions/checkout?

Same thing: https://github.com/diegorusso/cpython/actions/runs/12949425398

BTW also the GitHub editor was complaining about the retry.

Thanks, and there it is on test.yml:

Invalid workflow file: .github/workflows/build.yml#L258
The workflow is not valid. In .github/workflows/build.yml (Line: 258, Col: 11): Error from called workflow diegorusso/cpython@6a298de (Line: 40, Col: 7): Unexpected value 'retry'

https://github.com/diegorusso/cpython/actions/runs/12949425427

It does look like actions/checkout does have a non-configurable 3-attempt retry already built-in:

I think here we are looking at this from the wrong angle. If you see the failures posted initially, they don't fail while checking out the repo.
It is not started at all. After it prints the env variable there is nothing. I have the feeling that there is some infrastructure issue in running that action on a specific node.
Even if we put the retry 100 times, they won't be executed as this fails even before to start the process.

Yes, that's the impression I get too.

Looking more closely at the raw logs (https://github.com/python/cpython/actions/runs/12934438169/job/36075486419?pr=129232 > ⚙️ > View raw logs), the checkout does actually succeed.

For some reason, the next step just doesn't start.

Comparing with a passing build:

Oh wow, I didn't remember that we had access to these raw logs. They are useful indeed.
So the retry is pointless because it actually doesn't fail on the checkout.
