Migration from v1.0 to v2.0

To migration integration from RoadRunner v1. to v2. follow the next steps.

Update Configuration

Second version of RoadRunner use single worker factory for all of its plugins. This means that you must include a new section into your config server which is responsible for the worker creation. Limit service no longer presented as separate entity but rather part of specific service configuration.

rpc:
  listen: tcp://127.0.0.1:6001

server:
  command: "php tests/psr-worker-bench.php"

http:
  address: "0.0.0.0:8080"
  pool:
    num_workers: 4

Read more in config reference.

No longer worry about echoing

RoadRunner 2.0 intercepts all output to the STDOUT, this means you can start using default var_dump and other echo function without breaking the communication. Yay!

Explicitly declare PSR-15 dependency

We no longer ship the default PSR implementation with RoadRunner, make sure to include one you like the most by yourself. For example:

$ composer require nyholm/psr7

Update Worker Code

RoadRunner simplifies worker creation, use static create() method to automatically configure your worker:

<?php

use Spiral\RoadRunner;

include "vendor/autoload.php";

$worker = RoadRunner\Worker::create();

Pass the PSR-15 factories to your PSR Worker:

<?php

use Spiral\RoadRunner;
use Nyholm\Psr7;

include "vendor/autoload.php";

$worker = RoadRunner\Worker::create();
$psrFactory = new Psr7\Factory\Psr17Factory();

$worker = new RoadRunner\Http\PSR7Worker($worker, $psrFactory, $psrFactory, $psrFactory);

RoadRunner 2 unifies all workers to use similar naming, change acceptRequest to waitRequest:

while ($req = $worker->waitRequest()) {
    try {
        $rsp = new Psr7\Response();
        $rsp->getBody()->write('Hello world!');

        $worker->respond($rsp);
    } catch (\Throwable $e) {
        $worker->getWorker()->error((string)$e);
    }
}

Update RPCs

To create RPC client use new Goridge API:

$rpc = \Spiral\Goridge\RPC\RPC::create('tcp://127.0.0.1:6001');
