AttributeError: 'Path' object has no attribute 'walk'

[Goldziher]

Things to check first

• I have searched the existing issues and didn't find my bug already reported there

• I have checked that my bug is still present in the latest release

AnyIO version

4.6.0

Python version

3.11

What happened?

Anyio.Path implements the walk method which is available in pathlib.Parth from python 3.12 onwards. For lower versions of python, this causes anyio.Path.walk to through an attribute error.

I expected anyio to implement an alternative using os.walk on lower python versions, or at least to through an informative error instructing the user.

How can we reproduce the bug?

Try using anyio.Path.walk in a lower Python version.

IIRC, implementing Path.walk() was not trivial, and I was pressed for time as there were other urgent updates to be done. But if you'd like to take a stab at this, I'm willing to review a PR. But by no means is this a bug.

[smurfix]

Path.walkdoesn't exist in Python <3.12 (and throws an AttributeError when you try to use it), so why would I expect a different behavior from anyio.Path.walk?

[agronholm]

I suppose because there are other methods that I did implement for all Python versions where their stdlib counterparts required a specific minimum Python version. I can't remember off hand which methods those were though.

Well, its a question of documentation in this case. I can submit a PR.

BUT - arguing with me whether this is a bug or not, will not in any way help your users, who will eventually find this issue and either traceback to this issue or have to debug it like I have done to find it.
