Test script:
---------------
The script is this one :
function amqp_connection() {
$amqpConnection = new AMQPConnection();
$amqpConnection->setLogin("guest");
$amqpConnection->setPassword("guest");
$amqpConnection->setVhost("/");
$amqpConnection->connect();
if(!$amqpConnection->isConnected()) {
die("Cannot connect to the broker, exiting !\n");
}
return $amqpConnection;
}
function amqp_receive($exchangeName, $routingKey, $queueName) {
$amqpConnection = amqp_connection();
$channel = new AMQPChannel($amqpConnection);
$queue = new AMQPQueue($channel);
$queue->setName($queueName);
$queue->bind($exchangeName, $routingKey);
while($message = $queue->get()) {
echo("Message #".$message->getDeliveryTag()." '".$message->getBody()."'");
if($message->isRedelivery()) {
echo("\t(this message has already been delivered)");
}
// just for testing purpose, shows how to manually remove a message from queue
if(rand(0,6) > 4) {
$queue->ack($message->getDeliveryTag());
echo("\t(this message has been removed from the queue)");
}
print_r($message->getMessageId());
echo "\n";
}
if(!$amqpConnection->disconnect()) {
throw new Exception("Could not disconnect !");
}
}
function amqp_send($text, $routingKey, $exchangeName){
$amqpConnection = amqp_connection();
$channel = new AMQPChannel($amqpConnection);
$exchange = new AMQPExchange($channel);
$exchange->setName($exchangeName);
$exchange->setType("fanout");
$message = $exchange->publish($text, $routingKey);
if(!$message) {
echo "Error: Message '".$message."' was not sent.\n";
} else {
echo "Message '".$message."' sent.\n";
}
if (!$amqpConnection->disconnect()) {
throw new Exception("Could not disconnect !");
}
}
// lets send a message with a "random" content (the date)
amqp_send("Message added at this date: ".date(DATE_RFC822), "action", "amq.fanout");
// you need to sleep for 1 sec if you want to be able to receive the message you just sent ("limitation" must be on the broker side)
sleep(1);
// now we receive messages from the queue we just sent a message on
amqp_receive("amq.fanout","action","action");
Expected result:
----------------
There should not be any memory leak
Actual result:
--------------
A memory leak appears
