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

I'm going to take a stab at chown and chroot.

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 _os module that has all the built-in functions rather than the separate posix and nt modules that CPython has.

Ah, gotcha..so for chown and chroot methods, i'd reference the functionality and behavior in posixmodule.c

Yep, and you can use the #[cfg(unix)] attribute to make sure they're only available on unix.

cool cool, thanks!

PR #1524 has an implementation of os.system.

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!

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.

It's always possible to just do extern "C" { fn ctermid(...) -> ...; }; the libc crate isn't required for calling in to native functions.

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.

hi @coolreader18 is the list here #1175 (comment) updated? i'd like to start working on one of the API's thanks!

@AthulMuralidhar I think of that list,

• ctermid
• fchdir
• getgrouplist
• getlogin
• getpriority

still need to be implemented in os.rs

thanks for the quick reply @coolreader18 i'll try to work on ctermid and fchdir

getlogin: #2441

Hi, let me work on getgrouplist: #2449

Let me work on getpriority and setpriority next: #2453

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.

Run whats_left.sh and take a look at the output for os. 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!

I added a note to the issue body to check posix or nt for re-export.
