bpo-40280: select: Use NULL for empty fdset (GH-31865) by tiran · Pull Request #31865 · python/cpython

bedevere-bot

wasm32-emscripten does not support exceptfds and requires NULL. Python
now passes NULL instead of a fdset pointer when the input list is empty.
This works fine on all platforms and might even be a tiny bit faster.
