devenv `devenv update` doesn't update

Describe the bug devenv update doesn't update the lockfile.

To reproduce

Here's a gist with all the files. The config was entirely generated by devenv init, except it's wrong by default[^1], so I added unset P1 per the official advice (see the very bottom of the wiki page) to avoid errors when loading the env. The .gitignore is larger, as devenv init was run in an existing project.

Upon enabling the devenv via direnv, devenv complains that the lockfile should be updated.

$ cd -
/home/xr587/projects/foo
direnv: loading ~/projects/foo/.envrc

However, running devenv update doesn't change the lockfile. Subsequent env loads show the same ✨ devenv 1.0.8 is newer than devenv input message.

By the way, devenv update seems to ignore errors altogether. Try e.g. getting rate-limited by GitHub with enough devenv update calls:

devenv update proceeds as if no errors were encountered and exits with a zero exit code.

Version

devenv 1.0.8 (x86_64-linux)

[^1]: The config generated by devenv init has direnv errors with $PS1.

@k3yss can you take a look?

@viluon I can't reproduce devenv update not updating to the 1.0.8 version, this is the command I am running:

If possible, can you provide another example that is more easily reproducible? I think the issue may be related to the .direnv or .devenv directory being present. If you can upload the entire project somewhere, it might be more reproducible that way.

I can successfully reproduce the GitHub rate limit bug, and I will look into it.

@k3yss as luck would have it, my own subsequent attempts to reproduce the first issue also failed, which is lavishly weird. I should have backed up the entire project with the failing update. After removing devenv/direnv files from it and running devenv init again I could not reproduce the original problem.

That's not to say devenv init is without its issues, it certainly creates the wrong direnv config by default:

devenv-repro on  main 
❯ git status
On branch main

nothing to commit (create/copy files and use "git add" to track)

Thank you for looking into the rate limit bug. If the error handling of devenv update is suspect, perhaps the rate limit thing and the fail to update the lockfile share a root cause.

direnv: PS1 cannot be exported. For more information see https://github.com/direnv/direnv/wiki/PS1

This issue is mostly related to how direnv handles your terminal prompt. For my terminal config I see no such errors and I think if you use a more simpler prompt you won't have to edit the .envrc at all. Here is what happens when I do a devenv init

~/sandbox/cachix/issues/init » devenv init                                                                                                                                         k3ys@nixos

This looks like it was GitHub rate limiting.
