refs/heads/master from [~incarose]
[ https://git-wip-us.apache.org/repos/asf?p=activemq-artemis.git;h=75a4e78 ]
Change keep alive ratio to 1.5 from 0.75
Fixes: ARTEMIS-397
>From mqtt specs:
“If the Keep Alive value is non-zero and the Server does not receive a
Control Packet from the Client within one and a half times the Keep
Alive time period, it MUST disconnect the Network Connection to the
Client as if the network had failed [MQTT-3.1.2-24]. “
> MQTT protocol - connection TTL = keepAliveTimeSeconds * 750

> Key: ARTEMIS-397
> URL: https://issues.apache.org/jira/browse/ARTEMIS-397
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 1.0.0, 1.1.0, 1.2.0
> Reporter: hiawui
>
> For MQTT protocol, the connection TTL is equal to keepAliveTimeSeconds * 750,
> causes connections always disconnected by timeout. Is it a bug? or why?
> {code:title=MQTTProtocolHandler.java:159|borderStyle=solid}
> void handleConnect(MqttConnectMessage connect, ChannelHandlerContext ctx)
> throws Exception {
> this.ctx = ctx;
> connectionEntry.ttl = connect.variableHeader().keepAliveTimeSeconds() *
> 750; // this line!!!, why not multiply by larger than 1000?
> String clientId = connect.payload().clientIdentifier();
> session.getConnectionManager().connect(clientId,
> connect.payload().userName(), connect.payload().password(),
> connect.variableHeader().isWillFlag(), connect.payload().willMessage(),
> connect.payload().willTopic(), connect.variableHeader().isWillRetain(),
> connect.variableHeader().willQos(),
> connect.variableHeader().isCleanSession());
> }
> {code}
