To resolve #736

Axler1 · 2025-04-14T17:56:54Z

@eljamm , could you please review it? I am encountering some problems when running the example and the test.

For the test, I get the following error when executing this command: nix --extra-experimental-features "nix-command flakes" build .#checks.x86_64-linux.projects/mcaptcha/nixos/tests/basic

error: suspicious ownership or permission on '/nix/store/i9dmdq6rxhapj7jndvi19h60lr430qcf-boot.json.drv.chroot/root/nix/store/235hwkfrhxjgzwms9cis8h58f7ilb3qq-boot.json' for output 'out'; rejecting this build output

For the example, I get the following error when executing this command: nix --extra-experimental-features "nix-command flakes" build .#checks.x86_64-linux.projects/mcaptcha/nixos/examples/basic

Let's remove this file, since it's not testing anything

eljamm · 2025-04-14T20:06:10Z

Please delete the projects-old/mCaptcha directory

eljamm · 2025-04-14T20:07:33Z

The directory should be projects/mCaptcha, not projects/mcaptcha. Please mind the letter's case.

eljamm · 2025-04-14T20:25:03Z

From the error you got, we know that this example is not going to be enough to set up the service. Lets just delete this file and set the example attribute to null examples.basic = null; to indicate that it's something we want, but is not available, yet.

error: attribute 'database' missing at /nix/store/nmsrnrwd7yw953rsr23myp2xcjwcvixp-source/projects/mcaptcha/services/mcaptcha/module.nix:155:81: 154| assertion = (!cfg.database.createLocally) -> (cfg.settings.database.username != null); 155| message = "If `${opt.database.createLocally}` is not specified, then `${opt.settings.database.username}` must be specified"; | ^ 156| }

eljamm · 2025-04-14T20:25:38Z

Same comment as the service example. Let's remove this since it's not simple to set up.

If examples.basic = null; then there is no example to import.

Suggested change

I though the basic test did something, but apparently that wasn't the case. Let's just remove this file.

Could you please run the tests to see if it's my system that is causing the issues? 🙏

eljamm · 2025-04-16T07:40:33Z

I think the command fails because the Nix store isn't properly supported when it's mounted on an NFS/NTFS filesystem 0 1, if that's what you're doing. The project tests themselves are fine, since they're passing in CI.

eljamm · 2025-04-16T07:50:00Z

We don't need projects/mCaptcha/programs since I think the mcaptcha and mcaptcha-cache artefacts only run properly in the context of the service module.

Axler1 · 2025-04-16T18:14:43Z

Yeah, so that's what it was about.
