Lock not properly acquired when using asyncio.wait_for()

[marcmonfort]

When trying to use asyncio.wait_for() to add a timeout to acquire(), seems that it is not being properly acquired for the current task.

lock = RWLock()
try:
    await asyncio.wait_for(lock.writer_lock.acquire(), timeout=5)
    lock.writer_lock.release()
except asyncio.TimeoutError:
    pass

Traceback

Traceback (most recent call last):
  File "/home/marc/test/rwlock/venv/lib/python3.10/site-packages/aiorwlock/__init__.py", line 147, in _release
    self._owning.remove((me, lock_type))
ValueError: list.remove(x): x not in list

During handling of the above exception, another exception occurred:

This same script using python built-in async lock works

lock = asyncio.Lock()
try:
    await asyncio.wait_for(lock.acquire(), timeout=5)
    lock.release()
except asyncio.TimeoutError:
    pass
