Advanced retry implementation.

Installation

composer require gos/yolo

Example

Perform an action

$pusher->push($notification); #send notification over network

With YOLO :

use Gos\Component\Yolo\Yolo;

$maxRetry = 10; // Default is 5
$timeout = 10; // Default is 5 (in second), set 0 for not timeout
$allowedException = ['RuntimeException']; // empty by default, consider exception as a "success"
$yoloPush = new Yolo(array($pusher, 'push'), array($notification), $maxRetry, $timeout);
$yoloPush->run();

Sometimes we need more swag to retry over a webservice.

use Gos\Component\Yolo\Yolo;

$yoloPush = new Yolo(array($pusher, 'push'), array($notification));
$yoloPush->tryUntil(function(){
    $result = false;
    if ($fp = @fsockopen('my-web-service.dev', 1337, $errCode, $errStr, 1)) {
        $result = true;
        fclose($fp);
    }

    return $result;
});

If your operation have an hight cost, perform it when service is available instead of dummy retry.

You also can do :

use Gos\Component\Yolo\Yolo;

$yoloPush = new Yolo(array($pusher, 'push'), array($notification));
$yoloPush->tryUntil($pusher);

By implementing Gos\Component\Yolo\YoloInterface on your object. Add isAvailable and return true when it's ok.

You also can attach a logger to yolo (We implement Psr\Log\LoggerAwareInterface) . Swag

use Gos\Component\Yolo\Yolo;

$yolo = new Yolo(function(){});
$yolo->setLogger($mySwagPsrLogger);

Built in Callback

Ping Back

use Gos\Component\Yolo\Yolo;
use Gos\Component\Yolo\Callback\PingBack;

$pingger = new PingBack('127.0.0.1', 80);

$yoloPush = new Yolo(function(){});
$yoloPush->tryUntil($pingger);
