Public bug reported:
Mosquitto 2.0.14 on Ubuntu
I have three subscribers to a topic with QoS 1. When I publish with QoS
0, all subscribers get a publish. When I publish with QoS 1, only two
subscribers get a publish.
QoS 0:
2022-01-08T21:43:01: Received PUBLISH from mqttspy-neko (d0, q0, r0, m0,
'generic/time', ... (15 bytes))
2022-01-08T21:43:01: Sending PUBLISH to acclock02 (d0, q0, r0, m0,
'generic/time', ... (15 bytes))
2022-01-08T21:43:01: Sending PUBLISH to acclock01 (d0, q0, r0, m0,
'generic/time', ... (15 bytes))
2022-01-08T21:43:01: Sending PUBLISH to mqttspy-neko (d0, q0, r0, m0,
'generic/time', ... (15 bytes))
This is fine; all three get a publish.
QoS 1:
2022-01-08T21:53:07: Received PUBLISH from mqttspy-neko (d0, q1, r0, m97,
'generic/time', ... (15 bytes))
2022-01-08T21:53:07: Sending PUBLISH to acclock01 (d0, q1, r0, m188,
'generic/time', ... (15 bytes))
>>>Note acclock02 missing<<<
2022-01-08T21:53:07: Sending PUBLISH to mqttspy-neko (d0, q1, r0, m43,
'generic/time', ... (15 bytes))
2022-01-08T21:53:07: Sending PUBACK to mqttspy-neko (m97, rc0)
2022-01-08T21:53:07: Received PUBACK from mqttspy-neko (Mid: 43, RC:0)
2022-01-08T21:53:07: Received PUBACK from acclock01 (Mid: 188, RC:0)
acclock02 is not being notified (exactly the same software/ hardware as
acclock01, just two devices of the same kind).
I am missing something?
