Mise tasks hang with no output

[thedavidharris]

Attempting to run mise tasks has occasionally just hung when running in our CI environment.

mise run generate:environment runs a task that looks like this:

#!/bin/bash
#MISE description="Generates developer dotenv file from Google Cloud Secrets Manager"
#MISE depends=["authenticate_gcloud_cli"]
#MISE depends_post=["generate:swift_config_files"]

# content

But it never even seems to get to the point of actually invoking the task. With verbose output, this is the output that we get, and it will just loop over and over outputting this block until the job is killed.

DEBUG ARGS: /usr/local/bin/mise hook-env -s bash

DEBUG $ /bin/bash --noprofile -c . /Users/distiller/.local/share/mise/plugins/gcloud/bin/exec-env
export -p

Re-runs sometimes result in a success.

I narrowed this down to what I think is a dependency loop. mise considering this scenario a dependency loop, which doesn't make sense (or I have an incorrect idea of how depends and depends_post works)

This is effectively the setup:

File: task_a
#MISE depends=["task_c]
#MISE depends_post=["task_d"]

echo "Hello"

File: task_b
#MISE depends=["task_e]
#MISE depends_post=["task_f"]

echo "Hello"

File: task_c   <EMPTY>

File: task_d   <EMPTY>

File: task_e <EMPTY>

File: task_f <EMPTY>

And running mise task reps will show the dependency loop forever. Seems like any depends_post will trigger this loop.

And now full circle, even getting rid of the depends loop, seems like the task is still freezing with the output in the original item. Some have no output and it just looks like this:

DEBUG ARGS: mise run generate:swift_config_files
DEBUG config: ~/project/mise.toml

Too long with no output (exceeded 10m0s): context deadline exceeded

Tried removing all dependencies from all scripts; even after this it still hangs, so seems like the issue isn't with dependencies.

Looks like it's hanging sometime after the first process starts but before anything continues. I am calling mise run from other mise tasks, to avoid some of the dependency loop issues above, could that cause some process issues here?

You can run mise tasks deps to see how stuff is connected, if it just keeps scrolling you still have a loop.

I thought this was the original case, but as noted in the follow-up comment, even after removing all dependencies, we are still seeing hangs.
