pathlib.path.rglob no longer returns sorted files starting at 3.12 #142972
Description
Bug report
Bug description:
Until 3.11 included, all rglob calls were always returning sorted paths. Or at least, for the code snippet below. Starting at 3.12, this changed. I could not find any warning about it, so I thought it might be a bug.
Here is a reproducible example which can be run as uv run --python X script.py being X either 3.11 or 3.12:
import sys
import tempfile
from pathlib import Path
base = Path(tempfile.mkdtemp(prefix="rppf_tmp_"))
paths = [
