New submission from David Delassus: With Python 3.4.3-r1 (on Gentoo x86_64), I have encountered a strange behavior with the library "riak==2.5.3".
When closing the client connection, the library calls ``self._stop.set()`` where ``self._stop`` is a ``threading.Event``. The following error is raised (sometimes): ``` Exception ignored in: <bound method MultiPutPool.__del__ of <riak.client.multi.MultiPutPool object at 0x7fe166fe7dd8>> Traceback (most recent call last): File "/home/linkdd/devel/projects/link-framework/venv3/lib/python3.4/site-packages/riak/client/multi.py", line 110, in __del__ File "/home/linkdd/devel/projects/link-framework/venv3/lib/python3.4/site-packages/riak/client/multi.py", line 97, in stop File "/usr/lib64/python3.4/threading.py", line 518, in set File "/usr/lib64/python3.4/threading.py", line 360, in notify_all File "/usr/lib64/python3.4/threading.py", line 343, in notify TypeError: 'NoneType' object is not callable ``` When going in the ``threading`` module, I have found the following line: ``` waiters_to_notify = _deque(_islice(all_waiters, n)) ``` I added just before: ``` print(_deque, _islice, all_waiters, n) ``` Just to see that ``_deque`` and ``_islice`` are both **None**. They are imported from the modules ``collections`` and ``itertools`` correctly though. ---------- components: Library (Lib) messages: 268974 nosy: linkdd priority: normal severity: normal status: open title: _deque and _islice are sometimes None type: crash versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27360> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
