Cancel automatic reconnect calling connect or disconnect

[SgtSilvio]

Hey there. Is there any chance to cancel automatic reconnect? Calling disconnect() won't help since it will throw because we are not connected.

Hi @degill Yes, you can add a DisconnectedListener and set reconnect to false, for example:

final AtomicBoolean cancelReconnect = new AtomicBoolean(false);
Mqtt5Client.builder()
        .automaticReconnectWithDefaultConfig()
        .addDisconnectedListener(context -> {
            if (cancelReconnect.get()) {
                context.getReconnector().reconnect(false);
            }
        })
        ...

            }
        })
        ...

@SgtSilvio Assuming, there is already an ongoing delayed reconnection started, I guess, this approach may fail?

I just ran into this rather un-expectedly.

I would expect disconnect() to also cancel and stop any pending reconnect task having to do the above seems a little strange to me as a user.

Hei @PMacho Did you find a solution to cancel the ongoing delayed reconnect? You won't be able to manually call connect either since the client thinks it's in the process of reconnecting.

Kind of. We wrote a wrapper around this client that imitates the reconnect by rebuilding and reconnecting all pipelines. It still suffers from the fact that occasionally the server refuses to reconnect. However, I can't share the source here. Sorry for that.

Just a hint if you are planning the same. When reconnecting you'll get messages from the server before actually subscribing.

Okay, thanks for the hint :).

@flopfl you're welcome
