I don't have 2fa authenticated on github yet, not sure if that's related but i just mentioned it in case.

This is a Registry error, see the logs when we query the API using the job id from your logs:

$ curl https://registry.purescript.org/api/v1/jobs/c15beb1c-580f-4f2e-a269-c7d77a4f43bf | jq .

      "level": "ERROR",
      "message": "Failed to clone git tag: Cloning into '/tmp/tmp-2210958-ehZufsMfSvEF/foldable-traversable-extra'...\nfatal: could not read Username for 'https://github.com': No such device or address",

    }
  ],

  "ref": "v0.0.4",
  "success": false
}

That tag was created at 13:43, and the logs happen at 13:44, so I think this is a bug? I'll move the issue to the registry repo.

@thomashoneyman any clue what might be happening here? The spago config seems alright

[thomashoneyman]

The first error is strange:

Failed to clone git tag: Cloning into '/tmp/tmp-2210958-ehZufsMfSvEF/foldable-traversable-extra'...\nfatal: could not read Username for 'https://github.com': No such device or address",

We clone the repository early in publishing: https://github.com/purescript/registry-dev/blob/ef989a119d79f25d315ab7dcee603792750b059c/app/src/App/API.purs#L370

Here's the implementation of that fetch call: https://github.com/purescript/registry-dev/blob/ef989a119d79f25d315ab7dcee603792750b059c/app/src/App/Effect/Source.purs#L78-L81

Under the hood it's just calling git on the command line: https://github.com/purescript/registry-dev/blob/ef989a119d79f25d315ab7dcee603792750b059c/app/src/App/CLI/Git.purs#L74-L80

@f-f @flip111 The error is not good, but I would guess this is happening because the repository field in the Spago config is incorrect:

https://github.com/flip111/purescript-foldable-traversable-extra/blob/d7e3c78766831c1d8e52091e34226bcdbb591209/spago.yaml#L18

It lists the repository as foldable-traversable-extra but the actual repository has a purescript prefix: https://github.com/flip111/purescript-foldable-traversable-extra

[flip111]

Thank you for looking into this. I changed the repo name and it worked. Let's keep this issue open to make a better error message.

[f-f]

Ah indeed! Thanks Thomas. I guess both the registry and spago should check for the existence of the repo before doing their thing.

[thomashoneyman]

What was actually output to the console from the Spago publish? The registry generally comments this line:

"Failed to clone repository flip111/foldable-traversable-extra at ref v0.0.4"

What error would y'all want instead? Some kind of preflight check that the repository exists, and an error "Repository flip111/foldable-traversable-extra does not exist."?

Some kind of preflight check that the repository exists, and an error "Repository flip111/foldable-traversable-extra does not exist."?

Yeah, errors from git clone are pretty generic, so we can offer a much better error just running this simple check

[f-f]

The errors returned to the user are the ones appearing in the API call, and the first one is pretty confusing: "Failed to clone git tag: Cloning into '/tmp/tmp-2210958-ehZufsMfSvEF/foldable-traversable-extra'...\nfatal: could not read Username for 'https://github.com': No such device or address"

[thomashoneyman]

I think a simple git ls-remote would be a good preflight check, with interaction disabled via GIT_TERMINAL_PROMPT=0 since if the repo doesn't exist GitHub will prompt for login in case it's private.
