New submission from David Ford (FirefighterBlu3):
the following warning is incorrectly reported as initiated at psycopg2/extras.py:314, it actually occurs inside the Twilio python module.
/usr/lib/python3.6/site-packages/psycopg2/extras.py:314: ResourceWarning: unclosed <ssl.SSLSocket fd=10, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('173.12.76.132', 39350), raddr=('52.72.8.76', 443)>
ts = super(NamedTupleCursor, self).fetchall()
namedtuple_Record:19: ResourceWarning: unclosed <ssl.SSLSocket fd=10, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('173.12.76.132', 57692), raddr=('107.23.182.60', 443)>
This is the snippet of my code which makes the Twilio API call over https (noted by the >>> line).
# get failed/undelivered
with (yield from self.aiopg_pool.cursor(cursor_factory=psycopg2.extras.NamedTupleCursor)) as c:
yield from c.execute(stmt_bad, (id,))
rows = yield from c.fetchall()
# make calls to twilio and fetch failure reasons
for r in rows:
>>> msg = self._twilio.messages.get(r.delivery_id)
errors[r.delivery_id] = r.recipient, msg.error_code, msg.error_message
my tool uses crossbar.io's python-autobahn asyncio classes which do not use threading to my knowledge. psycopg2/pool.py does use threading. python-twilio does not use threading either.
