Package: python3-twisted
Version: 16.6.0-2
Severity: important
Dear Maintainer,
Under stretch (and sid twisted=17.1.0), it is not possible to cancel a
DelayedCall in python3:
p.cancel()
File "/usr/lib/python3/dist-packages/twisted/internet/base.py", line 96, in
cancel
self._str = bytes(self)
TypeError: 'DelayedCall' object is not iterable
This is fixed in upstream from https://github.com/twisted/twisted.git:
$ git show 5a5e5ca33b2a552ae2ca91e5dd38bd75e07306ff
commit 5a5e5ca33b2a552ae2ca91e5dd38bd75e07306ff

DelayedCall needs to call str(self), not bytes(self) to work on Python 3
