error: attribute 'unix-socket' missing

[brianmay]

Describe the bug
After updating flake to latest devenv main, we get this error:

# devenv up

2. cd teslamate
3. git checkout dc64687ba8f150b9da664cc411c4f7111f231418
4. nix flake update
5. devenv up

git bisect shows this is the first bad commit eab7aa8

[domenkozar]

@brianmay what version of process-compose do you have?

[brianmay]

I had similar issues with nixos-24.05 (1.6.1) and nixos-unstable (1.27.0).

But the issue looks like it is with config.process.process-compose.unix-socket missing to me. i.e. it happens before we even try to run process-compose.

[sandydoo]

Should be fixed by #1161.

The process.process-compose option was not configured to merge its contents, so your changes here would override the defaults, including the unix-socket.

[JakobLichterfeld]

Should be fixed by #1161.

Thanks. The reported error regarding unix-socket is solved with devenv.url = "github:cachix/devenv/fed89fff44ccbc73f91d69ca326ac241baeb1726";

We now get:

Adapting to new namings, it runs fine.

process.managers.process-compose = {
  port = process_compose_port;
  tui.enable = true;
};

Thanks for quick investigation and fix.

🎉

Did process.process-compose.port do anything previously? I don't see any mention of it anywhere, which is why I didn't write a migration for it.

@ brianmay Can you elaborate on this? Edit: solved already :-)

[sandydoo]

Ah, it was unceremoniously removed in #1147. Unfortunate. I'll add a migration for it.
