When using a producer/session with a send timeout, send() doesn't throw an
exception if the timeout is reached.
---------------------------------------------------------------------------------------------------------------
Key: AMQ-2507
URL: https://issues.apache.org/activemq/browse/AMQ-2507
Project: ActiveMQ
Issue Type: Improvement
Components: Broker
Affects Versions: 5.3.0
Environment: All platforms, 5.3.x
Reporter: Dave Stanley
In the attached testcase we set a low broker memory limit (to force a producer
to block due to the memory usage limit being hit), and also set a sendtimeout
on the connection to force the producer.send() to return if it cannot send a
message within the timeout period.
On running the test the broker sends messages until the timeout kicks in. Once
the hits the memory limit it blocks and the producer.send() returns after the
timeout.
The problem is there is no way to know that the send() failed. This improvement
is to modify the session to throw an exception of some kind when the
sendTimeout is reached.
I have attached the testcase without a fix as its not clear the best approach
to fix.
One possible solution is to modify ActiveMQSession, but need some clarification
on whats the best JMSException to throw. It doesn't look like this is
explicitly spelled out in the JMS Spec.
General area is the send() method
protected void send(ActiveMQMessageProducer producer, ActiveMQDestination
destination, Message message, int deliveryMode, int priority, long timeToLive,
MemoryUsage producerWindow, int sendTimeout) throws
JMSException {
.....
if (sendTimeout <= 0 && !msg.isResponseRequired() &&
!connection.isAlwaysSyncSend() && (!msg.isPersistent() ||
connection.isUseAsyncSend() || txid != null)) {
this.connection.asyncSendPacket(msg);
if (producerWindow != null) {
// Since we defer lots of the marshaling till we hit the
// wire, this might not
// provide and accurate size. We may change over to doing
// more aggressive marshaling,
// to get more accurate sizes.. this is more important once
// users start using producer window
// flow control.
int size = msg.getSize();
producerWindow.increaseUsage(size);
}
} else {
// Handle send timeout here
if (sendTimeout > 0) {
Object response =
this.connection.syncSendPacket(msg,sendTimeout);
if(response == null) {
LOG.debug(getSessionId() + " timeout sending message: "
+ msg);
}
// What jms exception is most appropriate to throw here?
}else {
this.connection.syncSendPacket(msg);
}
}
}
