PEP 541 Request: pcntl

[Lewiscowles1986]

Project to be claimed

pcntl: (standard library)

Your PyPI username

LewisCowles1986: https://pypi.org/user/LewisCowles1986/

Reasons for the request

pcntl throws a module not found error for Windows users (or anyone not on Linux or Mac)
Those users think it's pythons fault. (I know it's not)

I've got a pcntl package which on windows gives a more useful error. Eventually I'd like to upstream it, but first I have to publish it. On OSX it doesn't break anything as it uses sys_meta hooks.

Maintenance or replacement?

I've looked and found that fcntl is deliberately not part of python for windows. I think this is a mistaken approach, as it makes the error message less clear.

Python ask which would make this irrelevant for (future) python version python/cpython#125568

As we can see the Python core route is likely to be slow

Hi @Lewiscowles1986,

I need more clarifications because as of right now, your request doesn't seem to really fall under a PEP 541 request. Are you trying to publish a package name but it's already taken? Or are you getting an error that the name is "forbidden" or "prohibited?"

Looking into your issue/discussion on python/cpython, however, it sounds like you wish to make some type of improvement in the error message output for fcntl. But, we don't release standard library names for obvious reasons, and feature requests of that nature are not related to PEP 541 requests.

Hi @Thespi-Brain happy new year.

My understanding was that PEP-541 related to the reserved names, and I needed to make a request under PEP-541 if I wanted to publish a shim package to improve user experience. I'm so sorry to have taken your time if this is incorrect. I wanted to fully explore options available.

I've not actually made any headway into cpython edits, but the shim package, which just gives windows users a better error.
I think, could help users who are on windows, to realise that they cannot use code, which requires pcntl, due to decisions made by python, relating to the standard library.

Now I'm not a regular windows user, and just had a wave of energy / anger due to how AWFUL the package mentioned error messages were, particularly for users with less experience. I Found the docs to be borderline beligerant on OS interface differences, which I accept might be too large a can of worms to open here. I Have successfully negotiated edits to the library using pcntl as a transitive dependency via amoffat/sh#740, but solving in each down-stream package seems an inefficient way to solve a central issue.

I'm fine if we decide this request is untennable, to close it, as it could focus future energy. Please just close if this isn't a discussion that will help either of us.

Thank you for your time.
