Direnv, project environment and zsh

Hi,

I have an issue involving direnv, a project environment and zsh.

I have in my .zshrc a line saying eval "$(direnv hook zsh)". This comes from the direnv installation guide.
I also created a project environment for one of my projects and a .envrc file containing flox activate to activate the project environment when entering the directory.

However when I enter the directory it seems that a loop is triggered and I get many messages like:

direnv: ([/Users/etorreborre/.local/share/flox/environments/etorreborre/default/bin/direnv export zsh]) is taking a while to execute. Use CTRL-C to give up.

What can I do about this? Thank you.

Did you use flox activate; or . <( flox activate; );?

For direnv you’ll want to be sure to use the second one.

That’s the same thing, I need to interrupt with Ctrl-C.

Actually it seems that it is not deterministic, sometimes it works ok.

I think I know what it is… And it would have been hard for you to debug. Somewhere in the activation of the environment, flox tries to access a repository. However I have a key in a Yubikey which requires me to press it when it blinks. If I do it, everything is ok.

I used the debug mode to activate the environment and I can see

+ /nix/store/l5100vm321ay7i2kanfcai6na1dp6lqx-git-minimal-2.39.1/bin/git -c 'credential.https://github.com.helper=!/nix/store/ifh1jqp2yc2pgiaf7fqgi4qpz0q82iyp-flox-0.0.10-r216/libexec/flox/gh auth git-credential' -C /Users/etorreborre/.cache/flox/meta/etorreborre fetch origin

Can this be deactivated? Maybe, even if that is not only to solve this issue but just to make activate faster?

Hej Eric

Thanks for helping out debugging this, i agree that could have been a tough one for us on our own.

The request is part of the auto update feature [1].
Disabling auto updates via [2]:

. <(FLOX_AUTOUPDATE=0 flox activate)

should get you around that.

Thanks for bringing this up,
in case of the . <(flox activate) we might prefer speed over updates anyway especially since this can cause issues with user interaction as you have experienced.

[1] flox-bash/activate.sh at db7efcacb5f5935b286006288f23f931a573a918 · flox/flox-bash · GitHub

[2] flox-bash/metadata.sh at db7efcacb5f5935b286006288f23f931a573a918 · flox/flox-bash · GitHub

Thanks Yannik. I still think that something is trying to access git even with FLOX_AUTOUPDATE=0.
If I use flox activate -v the last 2 lines before I need to press my Yubikey are

# echo "Supercharged by flox!" 1>&2

Does that help?

Thank you these logs do help.

To pinpoint the issue could you help me by answering a few questions:

  1. do you run the .envrc in a project with a flox.nix/project env? Does this project use git+ssh://git@github.com/... inputs?
    I can tell you’re activation .#ockam?
  2. do you have any shell hooks defined?
  3. do you still get multiple direnv: ... is taking a while messages?
  1. yes I am using .envrc in a directory with a project environment. The project inputs are the default flox ones inputs.flox-floxpkgs.url = "github:flox/floxpkgs";

  2. I have tried with no shell hook and with eval "$(starship init zsh)" (for prompts) and I get the same behaviour in 3.

  3. I see just one message and then the project environment is activated after 30s but this is not deterministic. Sometimes the environment is activated just after 2s

Hej Eric
Quick status update; we have diagnosed the problem and are working on a solution now.
Thanks for pointing us the right way!

@etorreborre I think I found the cause of this when I was working on the other direnv response for you.

It looks like flox isn’t detecting non-interactive shells, so if you have multiple envs in a project ( the default + any package ) it will try to prompt you to select. You won’t see the prompt because it’s not an interactive shell, and it’ll just hang.

If you instead explicitly use . <( flox activate -e '.#default'; ); it shouldn’t hang.
I’ve filed a bug fix ticket for this so hopefully we can get it resolved soon.

I confirm that it works great, thanks!
