How to stop loop_forever() from a callback?

[dakhnod]

I have some code that sets up MQTT and runs loop_forever() in order to start the MQTT loop.

Now, I want to terminate that call from a callback like on_publish. As such, I have two questions:

1. Is there a better pattern to just publish a message and exit than running loop_forever? I would like to avoid starting another thread using loop_start
2. Currently, I am doing connection._thread_terminate = True, which is a hack, really. Is there a better way to stop the loop?

Thanks a lot!

Some simple thinking can go a long way. Executing connection.disconnect() does the trick.

Thanks for your work anyway!
