Installation

Composer

composer require docplanner/tasks-bundle

Add to AppKernel

	new \OldSound\RabbitMqBundle\OldSoundRabbitMqBundle,
	new DocPlanner\TasksBundle\DocPlannerTasksBundle,

Configuration

Define connection in OldSoundRabbitMqBundle configuration

https://github.com/php-amqplib/RabbitMqBundle

old_sound_rabbit_mq:
    connections:
        default:
            host:     "%rabbit.host%"
            port:     "%rabbit.port%"
            user:     "%rabbit.user%"
            password: "%rabbit.password%"
            vhost:    "%rabbit.vhost%"
            lazy:     false
            connection_timeout: 3
            read_write_timeout: 3
            keepalive: false
            heartbeat: 0

Define tasks configuration

docplanner_tasks:
    connection_name: default
    names_prefix: asd_

Define task

Define task payload

You have to extend class DocPlanner\TasksBundle\Tasks\BaseTaskPayload, whole object will be serialized using serialize function.

Define job

You have to extend class DocPlanner\TasksBundle\Tasks\BaseTask, method execute contains job body, method supports check that given payload is supported by task. You have to tag your task service with tag docplanner_tasks.task

WARNING

If method execute will return true it means task was executed successfully, false will cause requeuing for given task. Requeue number is limited by number defined on task class. If payload requeue number will exceed requeue limit, task will be moved to bury queue.

Examples

class SamplePayload extends BaseTaskPayload
{
	protected $someValue;
	
	public function __construct(string $someValue)
	{
		$this->someValue = $someValue;
	}

	public function getSomeValue() : string 
	{
		return $this->someValue;
	}
}

class SampleTask extends BaseTask
{
	/**
	 * @var SamplePayload $payload
	 */
	protected function execute(BaseTaskPayload $payload): bool
	{
		file_put_contents('/tmp/payload.log', var_export($payload, true) . PHP_EOL . $payload->getSomeValue());
		
		return true;
	}
	
	public function supports(BaseTaskPayload $payload): bool
	{
		return $payload instanceof SamplePayload;
	}
}

  sample_task:
    class: Your\Namespace\SampleTask
    tags:
      - { name: docplanner_tasks.task }

Produce tasks

Without delay

	$taskProducer = $container->get('docplanner_tasks.task_producer');

	$taskProducer->enqueue(new SamplePayload());

With delay

	$taskProducer = $container->get('docplanner_tasks.task_producer');

	$dateTime = new \DateTime('now + 2 minutes');

	$taskProducer->enqueue(new SamplePayload(), $dateTime);

Consume tasks

bin/console docplanner:tasks:run
