AttributeError: module 'py' has no attribute 'process'

[sylvorg]

Hello!

I'm getting the following traceback when trying to use pytest-forked, but when looking through the output of dir(py) right before ff = py.process.ForkedFunc(runforked), py does indeed seem to have process, so I'm not sure what the issue could be. This occurs even if I remove the other plugins.

Thank you kindly for the help!

Hi @sylvorg,

Can you post the output of pip --list?

but when looking through the output of dir(py) right before ff = py.process.ForkedFunc(runforked), py does indeed seem to have process

How are you verifying this, using a debugger? If so, see if you can get the file path of py: I suspect it might be resolving to pytest's internal py shim, instead of the installed py package.

[sylvorg]

Can you post the output of pip --list?

I'm actually using a nix-shell for this, so I'm not quite sure how to do that, unfortunately.

How are you verifying this...

I forked the repository and added a raise ValueError(dir(py)) right before the line; should I do that again with py.__file__ or similar?

Are you executing this with a virtualenv active? If not can you detail how?

Yes.

[sylvorg]

Sorry, my setup is a little complicated with a lot of interlinking functions, so could you give me an example of what exactly you need, like the packages in the shell, the command I'm using the run it, etc. ?

As for the py module, I'm getting /nix/store/lgz5z1nv7q9x82blqnqhmrxp3hfmh6gj-python3.11-py-1.11.0/lib/python3.11/site-packages/py/__init__.py as the path, and the following as the contents:

I ran into this issue too and found that py is going away/deprecated and it picks up a small shim which doesn't has process: https://github.com/pytest-dev/pytest/blob/main/src/py.py

[sylvorg]

Hello, @Flamefire! Sorry for not responding earlier; had finals to deal with! 😅 Did you manage to find a solution or similar for this? Or are you avoiding pytest-forked at the moment?

Hello, @Flamefire! Sorry for not responding earlier; had finals to deal with! 😅 Did you manage to find a solution or similar for this? Or are you avoiding pytest-forked at the moment?

Yes: Basically pip install py, see pytest-dev/pytest#12206

[mtelka]

Since py is in maintenance mode, isn't the way to go to stop to use it?

[The-Compiler]

Indeed, hence why this issue is open?

[mtelka]

Because py is still used?

[The-Compiler]

Yes, and that's why this issue exists and is open. Not sure what your point is?

[nicoddemus]

@mtelka

Since py is in maintenance mode, isn't the way to go to stop to use it?

Indeed it would be nice to not depend on py anymore, a quick search shows it is being used only in two places:

pytest-forked/src/pytest_forked/__init__.py

Line 21 in b274232

if isinstance(d[name], py.path.local):

pytest-forked/src/pytest_forked/__init__.py

Line 73 in b274232

ff = py.process.ForkedFunc(runforked)

The former seems easy to replace by checking if the object implements __fspath__ or something similar, the latter could be reimplemented in terms of multiprocessing from stdlib.

PRs are welcome in case anybody wants to set aside some time to work on this.
