Summary

I have a pre-commit hook which is a wrapper around ruff.
It basically calls:

cmd = ['ruff', 'check', '--fix', '--extend-ignore', 'ERA,RUF005,UP008,UP031,UP032,E501,UP009,PGH004,FURB156,CPY001,F821', '--stdin-filename', 'blah', '--', '/tmp/tmp4avodvqg']
process = subprocess.Popen(cmd, stdin=None, stderr=subprocess.STDOUT)
process.communicate()

The ruff subprocess now waits for stdin, which will never get any.

sys.stdin.isatty() returns True with prek, and False with pre-commit.

I can workaround it by passing stdin=open('/dev/null') to the subprocess.
