Can't pull my channel because of getaddrinfo -8 error

Here is my channel i'm trying to pull and keep getting that "SERVICE not

supported for `ai_socktype'" error

```

(channel

(name 'zero)

(url "https://codeberg.org/shinyzero0/guix-packages.git")

(commit

"1eacb7d9e2eb96c9d45b96af006b069e443c9ebc"))

```

the full log is

```

(repl-version 0 1 1)

(exception getaddrinfo-error (value -8))

```

It seems to work well on just the previous commit and i also tried some

rebasing/amending to change the "breaking" commit. Sometimes it worked,

but when i added other ones skipping the "breaking" one it throwed the

same error. Of course the channel as well as the package the commit adds

work well in my GUIX_PACKAGE_PATH

There is my `guix describe`:

```

(list (channel

(name 'shepherd)

Isn't that rather related to Codeberg being DDoS'd yesterday? Can you

retry now?

Hi, Josselin. Thanks for replying!

Well, actually i encountered the problem at least 20 days ago so it

definitely isn't related to recent DDOS attacks. Even if there were some

before, i could and can build the commit

e0d813eb175adb422a6993b173c6a3767957035d as well as my shepherd channel

which is hosted on codeberg too

Best wishes, Paul

Hello again.

I retried the build from codeberg and it still crashes

on any commit above e0d813eb175adb422a6993b173c6a3767957035d.

Also i pushed the repo to github

https://github.com/shinyzero0/guix-packagesand it still crashes with

the same error.

Best wishes,

Paul

Well, the issue seems to be with the commit that adds the transformed

polybar package like this:

```

(define-module (zero packages polybar))

(use-modules (guix packages)

(guix transformations)

(gnu packages wm))

(define-public

polybar-3.7.1

((options->transformation

'((with-version . "polybar=3.7.1"))) polybar))

```

Well, the bug seems coming from your channel. Could you update it and

make it compliant with Guix proper.

Somehow, I am going to close this issue because it is not a bug. :-)

Is it fine? Let us know if more details are required.

Cheers,

Hi Simon, Paul,

I've also run into this bug and I believe it is due to the error being

cached. This is clearly undesirable so this issue should stay open until

that is resolved.

My reasoning for thinking it is a cache issues is:

 - An issue with package transformations should never cause an

getaddrinfo error as Guix generally only goes up to servers for channels

and build packages.

 - I ran into this after my gitlab instance had some outage, and

persisted since my server came back up.

 - Pulling from a duplicate ref with the same hash succeeds, indicating

that the bug occurs before the checkout is fetched.

I'm happy to have a stab at working on this. Currently working on

reproducing this, it's not as simple as making the channel url point at

a closed port (eg. https://localhost:1212). I even tried binding a SCTP

server to the port, but I just get connection refused. Anyone have any

ideas about this?

Should the title be changed to something like "Guix can cache

getaddrinfo failures on `guix pull`"? (.. on the assumption that I'm

proven right ;-)

I'll assign this to myself, if there are no objections.

Kind regards,

Christina
