platform.node() does not return the latest hostname value #122525
Description

STR in case they help:
import platform, socket print(platform.node(), socket.gethostname()) # update the machine's hostname (for macOS it's Settings -> General -> Sharing) print(platform.node(), socket.gethostname()) # notice that this is reporting the old value
I'm guessing this is somewhat intentional.
platform.node()is equivalentplatform.uname().node, anduname()has a cached result.Oh I hadn’t noticed that there’s a
platform.uname()method as well. I guess this is somewhat intentional then. It would help to document thatunameand its dependents rely on a cached result that might be knowingly stale.Reacted by Peter BiermaMost of the functions in
platformare using cached values. However, I somewhat think that we should have a mean to invalidate this cache. I'll prepare a PR for that.
Bug report
Bug description:
I think it's because of how cache is implemented for the uname() helper: https://github.com/python/cpython/blob/5377f55b4e022041b7b57b5489c66c9b3c046c7e/Lib/platform.py#L890-L905.\
Given socket.gethostname() exists as well and respects the latest hostname value, maybe this issue is wontfix. Thought I would file it anyhow.
