Programmatically way to determine if paho-mqtt processes queue is empty?

Programmatically way to determine if paho-mqtt processes queue completed? For example, if I call client.disconnect(), the on_disconnect call back may need a bit more time to complete, is there a way I can test for this?

Hi,

no I don't think there is such feature currently. I agree it seems a valuable feature.

Depending on your use-case you might track per-message with wait_for_publish, or if the number of message is too large just using on_publish callback (like count number of published message, if it match number of emitted message, the queue is empty).

Yes... using on_publish method would seem to be possible in my use case. Is there a process to request such a feature be added? Seems straight-forward to add a small property or method to just report the queue length?
