AcquirerProxy object has no attribute locked #115942
Description
Bug report
Bug description:
According to the documentation, both multiprocessing.Manager.Lock and RLock should be the equivalent of an threading.Lock and RLock, but the underlying AcquirerProxy is missing the implementation of the .locked() method to query the state of the lock.
E.g.
from multiprocessing import Manager
from threading import Lock
if __name__ == "__main__":
lock_th = Lock()
lock_th.locked() # this one works
with Manager() as manager:
lock_man = manager.Lock()
lock_man.locked() # this throws an "AttributeError: 'AcquirerProxy' object has no attribute 'locked'"CPython versions tested on:
3.11, 3.12

pythongh-115942: Add `locked` to several multiprocessing locks

We clearly can do that. But, I cannot judge if we should: #115944
I am not a field expert in
multiprocessing, so I might miss a lot of things here. But, it seems rather straight-forward at the first sight.gh-115942: Add `locked` to several multiprocessing locks (#115944)

3.14 will have this new feature :)
