Abstract some Message Queuing system using the Adapter pattern

Work In Progress

This is a work in progress and unfinished business!

Usage example

producer.php

<?php

require_once 'autoload.php';

use Symfony\Component\EventDispatcher\EventDispatcher;
use BarbeQ\BarbeQ;
use BarbeQ\Adapter\AmqpAdapter;
use BarbeQ\Model\Message;

$messageDispatcher = new EventDispatcher();
$dispatcher = new EventDispatcher();

// AMQP
$connection = array('host' => 'localhost');
$exchange = array('name' => 'test_direct');
$queues = array(array('name' => 'test'));
$adapter = new AmqpAdapter($connection, $exchange, $queues);

// PDO
//$pdo = new \PDO('mysql:dbname=barbeq', 'root', '');
//$adapter = new \BarbeQ\Adapter\PdoAdapter($pdo, array(
//    'table' => 'queuing',
//));

$barbeQ = new BarbeQ($adapter, $messageDispatcher, $dispatcher);

$barbeQ->cook('test', new Message(array(
    'id' => 1,
    'foo' => 'bar',
)));
// or $barbeQ->publish(...), same action

consumer.php

<?php

require_once 'autoload.php';

use Symfony\Component\EventDispatcher\EventDispatcher;
use BarbeQ\Adapter\AmqpAdapter;
use BarbeQ\BarbeQ;
use Acme\PocBundle\Consumer\TestConsumer;

$messageDispatcher = new EventDispatcher();
$dispatcher = new EventDispatcher();

// AMQP
$connection = array('host' => 'localhost');
$exchange = array('name' => 'test_direct');
$queues = array(array('name' => 'test'));
$adapter = new AmqpAdapter($connection, $exchange, $queues);

// PDO
//$pdo = new \PDO('mysql:dbname=barbeq', 'root', '');
//$adapter = new \BarbeQ\Adapter\PdoAdapter($pdo, array(
//    'table' => 'queuing',
//));

$barbeQ = new BarbeQ($adapter, $messageDispatcher, $dispatcher);

$testConsumer = new TestConsumer();
$barbeQ->addConsumer('test', $testConsumer);

// Trace what's happening
$barbeQ->addListener('barbeq.pre_consume', function(ConsumeEvent $event) {
    echo sprintf("Start consuming message #%d\n", $event->getMessage()->getMetadataValue('index'));
});

$barbeQ->addListener('barbeq.post_consume', function(ConsumeEvent $event) {
    echo sprintf("Memory: %s, Time: %0.04fs\n", $event->getMessage()->getMemory(), $event->getMessage()->getTime());
});

$barbeQ->eat('test', 5);
// or $barbeQ->consume(...), same action
