[Docutils-develop] [docutils:bugs] #471 0.20 fails tests on pypy3

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

> It is a "false alarm", the different output should not trigger a test failure.

Indeed. I'm not sure if the different output from PyPy3 is actually intentional but I don't think it should cause a test failure anyway.

> How do you start the test with PyPy3?

(using docutils-0.20 unpacked from sdist)

```
pypy3 -m venv .venvpypy
. .venvpypy/bin/activate
pip install .
python test/alltests.py
```

> Does the same error show if you run "docutils/test/alltests.py" with Python 3.9.16?

No. All tests pass then. I think the `PosixPath(…)` part of exception is PyPy-specific:

```
$ python3.9 -c 'from pathlib import Path; Path("foo").read_text()'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3.9/pathlib.py", line 1266, in read_text
    with self.open(mode='r', encoding=encoding, errors=errors) as f:
  File "/usr/lib/python3.9/pathlib.py", line 1252, in open
    return io.open(self, mode, buffering, encoding, errors, newline,
  File "/usr/lib/python3.9/pathlib.py", line 1120, in _opener
    return self._accessor.open(self, flags, mode)
FileNotFoundError: [Errno 2] No such file or directory: 'foo'
$ pypy3.9 -c 'from pathlib import Path; Path("foo").read_text()'
