[paho-dev] Return codes for subscribe and publish methods in Python

[Chamila De Alwis <chamilad@xxxxxxxx>]

Hi,

I'm working with ActiveMQ as the message broker and I've enabled SimpleAuthenticationPlugin [1] to authorize users based on username and password. When connecting with Paho-MQTT Python library with wrong credentials, the subscribe() method still returns result code 0 - SUCCESS, instead of a NO_CONN. This makes it impossible to determine if the authentication went bad at the message broker.

The publish.single() method doesn't return anything at all. Is this the intended way and is there a another way to determine success of these functions or is it a possible improvement?

I'm using paho-mqtt 1.1 version.
