[New-bugs-announce] [issue36813] QueueListener not calling task_done upon termination

[Bar Harel]

New submission from Bar Harel <bzvi7919 at gmail.com>:

QueueListener does not call task_done upon termination, causing an unsuspecting thread to deadlock.

Steps to reproduce:

>>> import queue
>>> q = queue.Queue()
>>> from logging.handlers import QueueListener
>>> h = QueueListener(q)
>>> h.start()
>>> h.stop()
# Goodbye cruel world!
>>> q.join()

Fixing and uploading a patch as we speak.
