`python` under `venv` misbehaves when using `subprocess.run` #308

Closed oroppas closed 1 year ago

(graalpy) [ryuta@fedora bugs]$ which python
/home/ryuta/packages/graalvm/graalpy/bin/python
(graalpy) [ryuta@fedora bugs]$ ls -l `which python`
lrwxrwxrwx. 1 ryuta ryuta 7 Dec 10 16:05 /home/ryuta/packages/graalvm/graalpy/bin/python -> graalpy

Now executing the piece of code with python gives the error:

(graalpy) [ryuta@fedora bugs]$ python -c "import subprocess; subprocess.run(['python']+list(('-c','import os')))"
Traceback (most recent call last):

whereas graalpy works fine as expected:

(graalpy) [ryuta@fedora bugs]$ graalpy -c "import subprocess; subprocess.run(['python']+list(('-c','import os')))"
