Add support for QoS 2 #121

Open njh opened 4 years ago

njh commented 4 years ago

Support for local persistence for a message queue is a requirement before QoS 2 can be implemented.

@eLocker-UK it would be useful to know why you require QoS 2 and what you use case is. One of the things I have struggled with a bit is working out an API for providing feedback when a publish fails.

We use ruby-mqtt for test automation and we have a use case with QoS 2 to test. Unfortunately we can not, as it is not yet supported by ruby-mqtt.

When trying to use QoS anyway, i get this error: Connection error on publish: execution expired

Hope support for QoS2 is coming soon.
