Extend the os module #1175
Description
Currently, the python os module is missing many methods. Try adding a method to this module by editing the file vm/src/stdlib/os.rs.
This is an issue for new contributors, so please do not implement everything at once, so other people have a chance to go for it (or, actually, please implement all! >:)! ).
Note: Before working on platform-specific functions, check if they are members of posix or nt. Their members are reexported to os.

Ok, I'm working on get/set uid, guid etc. stuff

I'm going to take a stab at
chownandchroot.Also, as a general question, is the current goal to match CPython functionality here?
Currently it doesn't seem that the os module is implemented in C for CPython. Is the goal here to implement the Python os module in Rust as, for example, the sys module in CPython is implemented in C and not in Python?
Or am I completely missing something here?

Because Rust's cross-platform support is so much better than C's, we decided to implement a single
_osmodule that has all the built-in functions rather than the separateposixandntmodules that CPython has.immersinn commentedon Sep 23, 2019
Ah, gotcha..so for
chownandchrootmethods, i'd reference the functionality and behavior inposixmodule.ccoolreader18 commentedon Sep 23, 2019
Yep, and you can use the
#[cfg(unix)]attribute to make sure they're only available on unix.immersinn commentedon Sep 23, 2019
cool cool, thanks!

Hi, new here. I was just wondering how to start working on one of these outstanding implementations without having any overlap with others? Should we open a new issue for what we want to tackle and then have it assigned to us?
Thanks!
coolreader18 commentedon Jun 23, 2020
I'm so sorry for not responding earlier @nicholasraphael, if you're still interested you can feel free to just open a PR for it; there are a lot of functions and hopefully what you choose won't conflict if anyone else is working on something. You could also just comment what you're working on in this thread.

The libc rust module doesn't have an API for the ctermid function, so that's an issue for implementing os.ctermid.
coolreader18 commentedon Jul 23, 2020
It's always possible to just do
extern "C" { fn ctermid(...) -> ...; }; the libc crate isn't required for calling in to native functions.leopsidom commentedon Nov 29, 2020
Hey, I wanted to work on some of these issue. But how can I create tests for this ? Basically after I implement a method, how can I test if it's working as expected? Sorry quite new here.

I made a analysis to detemine the next important os module based on the real usage in GitHub public code. This is based on the master branch of this repo at the time of writing.
Feel free to use and modify it.

Implementing os.listxattr

Hi, is there something left to work on this?
Would like to pick it up.
DimitrisJim commentedon Sep 9, 2021
Run
whats_left.shand take a look at the output foros. Pick one of the functions, add a comment here that you've picked up the function so conflicts are minimized and start working on it!youknowone commentedon Sep 22, 2021

I'd like to look at gettingos.fwalkimplementedEdit: Looks like its already implemented in
os.py, even thoughwhats_left.pystill shows it as missing.fanninpm commentedon Apr 17, 2024

Thank you everyone to participate in this marathon for os module.
os module function are almost done. A few of them are left, but having an issue for that is not worth as before.
