Integration tests fail in NixOS using nix-build

jordilin commented 7 months ago

NixOS builds in sandboxed environments using nixbld users and /homeless-shelter as a $HOME. Those build users do not have .gitconfig setup, so git operations fail with error: could not lock config file /homeless-shelter/.gitconfig: No such file or directory. Complete output below after issuing nix build

Possible approaches I can think of:

Provide a gitconfig during the setup. Set up an env variable like GIT_CONFIG and GIT_CONFIG_NOSYSTEM so git commands make use of it. Believe env GIT_CONFIG is deprecated these days though.
I would not hard code expected $HOME values /home/test, such as https://github.com/davvid/garden/blob/main/tests/eval_test.rs#L201, so I'd set it up globally as const HOME: &'static str = "/home/test"; and use that as a reference.
NixOS nixbld users use HOME=/homeless-shelter (although that home does not actually exist) so using that would certainly fix all assertions and does not assume a home under a /home path

Hi Jordi, and thanks for the heads-up! I think we should be able to arrange to provide a gitconfig for use by the tests. We might be able to use git config commands inside of the temporary repositories we're creating and make sure they don't write to $HOME.

If that doesn't work then an environment variable should be able to handle it. I believe git supports $XDG_CONFIG_HOME so that might be another option.

https://gitlab.com/garden-rs/garden/-/blob/main/tests/integration/setup.sh?ref_type=heads#L24 is where we should be able to

git config user.name Garden
git config user.email garden@localhost

and then we won't interact with $HOME at all.

I knew this sounded familiar.. we had first run into this when setting up the .gitlab-ci.yml but the fix was regulated to just that entry point. Now we're fixing it in the tests directly. I should probably rewrite that shell script into a rust function in tests/common/mod.rs.

Thanks Jordi!

Thanks @davvid - this fixed it :+1:
