Python Test spawning infinite Pipenv processes

[rodrigocaus]

Type: Bug

Behaviour

On Python test discovery, several instances of Pipenv are spawned, looking like a nested sequence of fork calls. Closing the VSCode session does not solve.

Here is a print-screen of the Process Explorer:

The root command is:

/usr/bin -c . ~/.local/share/virtualenvs/suggestion-service-9KXSQYLP/bin/activate && echo 'e8b39361-0157-4923-80e1-22d70d46dee6' && python ~/.vscode/extensions/ms-python.python-2024.22.0-linux-x64/python_files/printEnvVariables.py

As a result of this, the computer's memory usage is exceeded and completely freezes my computer, requiring a restart. Several calls to pkill -9 pipenv could prevent the freezing if the problem is previously detected.

Steps to reproduce:

1. Set a pipenv Python interpreter
2. Click on Testing badge
3. Click on Refresh Tests

This seems like something might be broken with the activation script for that pipenv environment. Does running the activation script from an external terminal work?

[rodrigocaus]

I've ran the activation scripts from an external terminal (Gnome Ptyxis):

$ pipenv shell # from the project folder
$ source /home/rodrigocaus/.local/share/virtualenvs/suggestion-service-9KXSQYLP/bin/activate
$ . /home/rodrigocaus/.local/share/virtualenvs/suggestion-service-9KXSQYLP/bin/activate
$ bash -c  ". /home/rodrigocaus/.local/share/virtualenvs/suggestion-service-9KXSQYLP/bin/activate"

They all worked without any problems.

I've set the Python extension log level to trace, and I received the output:

This is the first time I received the [error] getActivatedEnvironmentVariables message. Even after the error, several instances of Pipenv keep spawning. I can only kill them using pkill.

Running the same command:

. /home/rodrigocaus/.local/share/virtualenvs/suggestion-service-9KXSQYLP/bin/activate && echo 'e8b39361-0157-4923-80e1-22d70d46dee6' && python /home/rodrigocaus/.vscode/extensions/ms-python.python-2024.22.0-linux-x64/python_files/printEnvVariables.py

on an external terminal work just fine.
