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.

I would like to do a quick summary of what is API still missing.

1. os.ctermid
2. os. environb
3. os.fchdir
4. os.fsencode
5. os.fsdecode
6. os.PathLike
7. os.getenvb
8. os.get_exec_path
9. os.getgrouplist
10. os.getgroups partially
11. os.getlogin
12. os.getpgrp
13. os.getpriority

...

I just scroll thought 10% on the os docs. There are still so many interfaces left to implement. 😛
