MongoClient.event_listeners does not work as documented:
@property
def event_listeners(self):
"""The event listeners registered for this client.
See :mod:`~pymongo.monitoring` for details.
"""
return self._event_listeners.event_listeners
One would expect for event_listeners to return the list of event listeners passed to MongoClient. However, this is what it actually does:
>>> from pymongo import event_loggers >>> listeners = [event_loggers.CommandLogger(), ... event_loggers.HeartbeatLogger(), ... event_loggers.ServerLogger(), ... event_loggers.TopologyLogger(), ... event_loggers.ConnectionPoolLogger()] >>> c = MongoClient(event_listeners=listeners) WARNING:root:No writable servers available. WARNING:root:No readable servers available. >>> c.event_listeners <bound method _EventListeners.event_listeners of <pymongo.monitoring._EventListeners object at 0x7fea50a8d2e0>> >>> c.event_listeners() ([<pymongo.event_loggers.CommandLogger object at 0x7fea4d090d90>], [<pymongo.event_loggers.HeartbeatLogger object at 0x7fea50a74ca0>], [<pymongo.event_loggers.ServerLogger object at 0x7fea50a74c40>], [<pymongo.event_loggers.TopologyLogger object at 0x7fea50a74c10>])
So there are multiple issues:
- it's not actually a property
- it doesn't return a list
- it doesn't return the Connection Pool listener
The expected behavior should be a property that returns all the listeners in one list:
... >>> c.event_listeners [<pymongo.event_loggers.CommandLogger object at 0x7feeab090d90>, <pymongo.event_loggers.HeartbeatLogger object at 0x7feeaea40c10>, <pymongo.event_loggers.ServerLogger object at 0x7feeaea40cd0>, <pymongo.event_loggers.TopologyLogger object at 0x7feeaea40ee0>, <pymongo.event_loggers.ConnectionPoolLogger object at 0x7feeaea40e80>]
