Hello,
when you execute this code ...
#!/usr/bin/env python
import pika
from itertools import count
counter = count(1)
def receive_callback(channel, method, properties, body):
print 'Received message {counter}: {body}'.format(
counter=counter.next(),
body=body
)
channel.basic_ack(delivery_tag=method.delivery_tag)
connection = pika.BlockingConnection(
pika.ConnectionParameters(
host='127.0.0.1',
port=5672,
)
)
channel = connection.channel()
channel.queue_declare(queue='testertest', durable=True)
channel.basic_qos(prefetch_count=1)
channel.basic_consume(
receive_callback,
queue='testertest'
)
print 'Waiting for messages ...'
channel.start_consuming()
you will get this Exception after N seconds (where N is defined at
SOCKET_TIMEOUT_THRESHOLD in pika/adapters/blocking_connection.py (default is
100))
Waiting for messages ...
Traceback (most recent call last):
File
"/usr/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line
293, in start_consuming
self.transport.connection.process_data_events()
File
"/usr/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line
103, in process_data_events
self.process_timeouts()
File
"/usr/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line
157, in process_timeouts
log.debug('%s: Timeout calling %s',
NameError: global name 'log' is not defined
This Exception makes it impossible for the process_timeouts method to
handle timeouts. Code, which uses BlockingConnection, will fail
in a unexpected way.
I attached a patch to fix this problem.
Cheers,
Robin
