CONNECTION_DRAINING handling

[long1eu]

How do you handle CONNECTION_DRAINING message?

I'm doing this:

private void handleConnectionDrainingFailure() {
        logger.log(Level.INFO, "FCM Connection is draining! Initiating reconnection ...");

        XMPPTCPConnection oldConnection = connection;
        oldConnection.disconnect();

        try {
            connect();
        } catch (XMPPException | SmackException | IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }

I have modified a little bit the ccsConnection class but it is almost the same because in connection draining I am calling the reconnect method:

public void reconnection() { BackOffStrategy backoff = new BackOffStrategy(); while (backoff.shouldRetry()) { try { initialize(); backoff.doNotRetry(); } catch (XMPPException | SmackException | IOException e) { logger.info("The notifier server could not reconnect after the connection draining message"); backoff.errorOccured(); } } }

@PostConstruct public void initialize() throws XMPPException, SmackException, IOException { // Create the connection connection = new XMPPTCPConnection(connConfiguration);

    // Connect
    connection.connect();

...

// Login to FCM

}

Hope it helps

Hi @long1eu

I just pushed the connection draining logic to the main branch if you want to check it out. Links:
