Move two os functions to extras - #188
Conversation
The os.getegid() and os.geteuid() are not available on all OS's. The `group_access` and `user_access` attributes of a file are **not** universally available.

Windows fix sounds good, just a point inline about potentially avoiding a Linux regression

I'm wondering if these 2 are worth handling separately, since they are available on Linux but some other attributes in this block aren't. The upshot being that on my Ubuntu machine...
# Without this change
❯ uv run python -m celpy -n 'stat("pyproject.toml").user_access'true
# With this change
❯ uv run python -m celpy -n 'stat("pyproject.toml").user_access'ERROR: <input>:1:1 no such member in mapping: 'user_access' | stat("pyproject.toml").user_access | ^There was a problem hiding this comment.
Super-helpful! Thanks! Important underlying principle: don't lump these functions together; each one is a unique, precious snowflake.

Ah that's even better 😎 . Comparing the full JSON of a stat("pyproject.toml") I see...

Good! Your comments make it clear I need Windows and Ubuntu Docker images to do more thorough testing.
Instead of an overall "all-or-nothing" test each extra feature individually to see if it's part of the current OS.
The os.getegid() and os.geteuid() are not available on all OS's. The
group_accessanduser_accessattributes of a file are not universally available.This treats each extra feature as potential available or unavailable. It no longer lumps the extra features into a composite "all-or-none" change.
Closes#177.
This also removes PR #178 and #179.
