Git repository subdirectories should be different inputs

[maxiem-ota-insight]

What happened?

When adding two different flakes as inputs in devbox.json based on private git input, devbox will interpret them as one input and therefore not install the dependencies correctly.

e.g. devbox.json:

"packages": [
    "git+ssh://git@gitlab.com/devbox-shims.git?dir=betteralign&ref=master&rev=17d2bedca4884176e0d08078aa42311053e531c2",
    "git+ssh://git@gitlab.com/devbox-shims.git?dir=recovergoroutine&ref=master&rev=593d44945851d912f0c2158c46cc76da445adc43",
]

devbox.lock:

{
    "git+ssh://git@git.otainsight.com/ota-insight-repos/ota-insight-platform/ota-insight-api/devbox-shims.git?dir=recovergoroutine&ref=master&rev=593d44945851d912f0c2158c46cc76da445adc43": {
      "last_modified": "1970-01-01T00:00:00Z",
      "resolved": "git+ssh://git@git.otainsight.com/ota-insight-repos/ota-insight-platform/ota-insight-api/devbox-shims.git?dir=recovergoroutine&ref=master&rev=593d44945851d912f0c2158c46cc76da445adc43"
    },
}

Only one of the inputs is considered, even though the dir parameter means they really are different individual inputs.

This may not be Devbox but instead a limitation of Nix itself: my understanding is that Nix flakes are designed for 1 flake per repo.

I think we could check by trying to have Nix build each ref and see if it works. If it does, then this might be a Devbox issue after all. Try running:

nix build "git+ssh://git@gitlab.com/devbox-shims.git?dir=betteralign&ref=master&rev=17d2bedca4884176e0d08078aa42311053e531c2"

and

nix build "git+ssh://git@gitlab.com/devbox-shims.git?dir=recovergoroutine&ref=master&rev=593d44945851d912f0c2158c46cc76da445adc43"

to see if Nix itself can handle the dir query param.

If Nix can't handle the dir query param then I think you'll need to refactor to a single top-level flake. Since flakes are ~ just an entrypoint into Nix code, you can still keep configurations in each subfolder and use the flake to expose them.

This may not be Devbox but instead a limitation of Nix itself: my understanding is that Nix flakes are designed for 1 flake per repo.

To my understanding, flakes own the directory they live in and all subdirectories under it. Not a repository.

I think we could check by trying to have Nix build each ref and see if it works. If it does, then this might be a Devbox issue after all. Try running:

Nix builds these without problem, in fact, even my original message builds just fine - the problem is that devbox has just removed one of the inputs. The input that is left, at random, builds just fine and is present in the PATH.

Referencing the same repository multiple times on different revisions (/ other modificators like dir) is a core feature of nix flakes.
e.g. this flake builds just fine:

{
  description = "A very basic flake";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
    testflake.url = "git+ssh://git@git.otainsight.com/ota-insight-repos/ota-insight-platform/ota-insight-api/devbox-shims.git?#betteralign";
    testflake2.url = "git+ssh://git@git.otainsight.com/ota-insight-repos/ota-insight-platform/ota-insight-api/devbox-shims.git?#recovergoroutine";
  };

  outputs = { self, nixpkgs, testflake, testflake2 }: {

    packages.x86_64-linux.hello = nixpkgs.legacyPackages.x86_64-linux.hello;

    packages.aarch64-darwin.default = self.packages.aarch64-darwin.hello;

  };
}

If Nix can't handle the dir query param then I think you'll need to refactor to a single top-level flake. Since flakes are ~ just an entrypoint into Nix code, you can still keep configurations in each subfolder and use the flake to expose them.

We've since refactored to a single flake with two outputs. We still experienced issues with adding two different outputs of that flake to our path, but I cannot reproduce this now.

Still, the original issue is a relevant problem that should be addressed imo.

Oh cool, thanks for teaching me something! And that does sound like a Devbox issue then, ya.
