* Pass cause through as $previous to Exception

* Open shouldBeConnected() for extension

Visibility from private to protected, because this method performs a
reconnect process that may be modified in subclass connection managers.

* Carry exception through in switchNodeIfNeeded() too

A PHP library for the very promising disque distributed job queue. Features:

  • Support for both PHP (5.5+) and HHVM
  • No dependencies: Fast connection to Disque out-of-the-box
  • High level API to easily push jobs to a queue, and retrieve jobs from queues
  • Easily schedule jobs for execution at a certain DateTime
  • Use the built in Job class, or implement your own
  • Smart node connection support based on number of jobs produced by nodes
  • Connect to Disque with the built-in connection, or reutilize your existing Redis client (such as predis)
  • Supporting all current Disque commands, and allows you to easily implement custom commands
  • Fully unit tested

Installation

$ composer require mariano/disque-php --no-dev

If you want to run its tests remove the --no-dev argument.

Usage

This library provides a Queue API for easy job pushing/pulling, and direct access to all Disque commands via its Client API.

Create the client:

use Disque\Connection\Credentials;
use Disque\Client;

$nodes = [
    new Credentials('127.0.0.1', 7711),
    new Credentials('127.0.0.1', 7712, 'password'),
];

$disque = new Client($nodes);

Queue a job:

$job = new \Disque\Queue\Job(['name' => 'Claudia']);
$disque->queue('my_queue')->push($job);

Schedule job to be processed at a certain time:

$job = new \Disque\Queue\Job(['name' => 'Mariano']);
$disque->queue('my_queue')->schedule($job, new \DateTime('+2 hours'));

Fetch queued jobs, mark them as processed, and keep waiting on jobs:

$queue = $disque->queue('my_queue');
while ($job = $queue->pull()) {
    echo "GOT JOB!";
    var_dump($job->getBody());
    $queue->processed($job);
}

For more information on the APIs provided, read the full documentation.
