Not so simple I'm afraid... pytest-xdist's own code still uses some py functionality, such as py.log, py.local, etc.

Will go ahead and try to remove that dependency.

looks like the py.log can be replaced pretty easily with just functools.partial(print, file=sys.stderr) (or lambda *a, **k: None in the non-debug case) -- I'll send a patch for that one

[nicoddemus]

Yeah I was working on that.

Unfortunately just hit a wall: pytest_xdist_make_scheduler receives a py.log instance. I guess we will need a round of deprecation for that parameter. 😬

I made a class which looks the same as the py.log thing -- and kept the usages the same

Cool.

I have some WIP replacing py.local with Path too, but I won't be able to push it in the next few hours... feel free to open a separate PR replacing py.log though.

[asottile]

alrighty #822 and #823 should be good to go now I think?

[nicoddemus]

AFAICT we no longer depend on py. 😁

[nicoddemus]

Rebased and ready for final review.
