Missing redis key containg set of queues bound to queue is caused
by removal all queues from the exchange. Hence, we should not raise an
exception but just return empty list of queues instead. This commit
fixes e.g. case publishing message against empty exchange:
import kombu
conn = kombu.Connection('redis://')
exchange = kombu.Exchange('name', type='direct')
exchange.declare(channel=conn.default_channel)
producer = conn.Producer()
producer.publish(
{'hello': 'world'},
exchange=exchange,
routing_key='queue1'
)
But it also fixes the case when last queue is unbound from exchange and
after publishing to this exchange:
import kombu
conn = kombu.Connection('redis://')
exchange = kombu.Exchange('name', type='direct')
queue1 = kombu.Queue('queue1', exchange=exchange, routing_key='queue1')
exchange.declare(channel=conn.default_channel)
queue1 = queue1.bind(channel=conn.default_channel)
queue1.declare()
producer = conn.Producer()
producer.publish(
{'hello': 'world'},
exchange=exchange,
routing_key='queue1'
)
queue1.delete()
producer.publish(
{'hello': 'world'},
exchange=exchange,
routing_key='queue1'
)

oid is not cached anymore due race conditions of oid in celery. Caching
oid is causing following exception:
OperationalError("
Cannot route message for exchange 'reply.celery.pidbox': Table empty or key no longer exists.
Probably the key ('_kombu.binding.reply.celery.pidbox') has been removed from the Redis database.
",)
This exception seems to be occuring when multiple celery workers
contains same oid.
