Perhaps we should use sys.version_info here as guard, so safe_exists can be dropped once only Python 3.8+ is supported?
if sys.version_info[:2] <= (3, 7):
def safe_exists(path: Path) -> bool:
# On Python<=3.7, this can throw on paths that contain characters
# unrepresentable at the OS level.
try:
return path.exists()
except OSError:
return False
else:

Good idea, will change it.

BTW. The reason this can happen at all is pretty funky.
pytest determines the rootdir by looking at all non-option arguments and finding the common ancestor etc.
But because this code runs before plugins are loaded, any plugin argument not prefixed by a -, such as test*bla in pytest --tx test*bla (as opposed to if the --tx=test*bla form was used) gets interpreted as a possible path. If it is actually a valid path then you'd have one seriously confused user...
I looked into fixing it but seems not really possible.

Yeah it is not simple due to how options are parsed. 😕
An equivalent for these py.path.local functions is needed for some upcoming py.path -> pathlib conversions.
Didn't call it absolute or absolute_path to avoid conflicts with possible variable names. Didn't call it abspath to avoid confusion with os.path.abspath.
The first commit adds analogues of
py.path.local'sbestrelpathandcommonfunctions to_pytest.pathlib.The second commit converts
_pytest.config.findpathsto use pathlib.The third commit coverts some random places to pathlib.
