Trying to get TYPO3 to work in worker-mode

[ochorocho]

I tried to get TYPO3 working in worker mode. I used the Custom Apps as a base.

This is what i have so far:

<?php

ignore_user_abort(true);

$classLoader = require dirname(__DIR__).'/vendor/autoload.php';

\TYPO3\CMS\Core\Core\SystemEnvironmentBuilder::run(0, \TYPO3\CMS\Core\Core\SystemEnvironmentBuilder::REQUESTTYPE_FE);
/** @var \TYPO3\CMS\Frontend\Http\Application $app */
$app = \TYPO3\CMS\Core\Core\Bootstrap::init($classLoader)->get(\TYPO3\CMS\Frontend\Http\Application::class);

// Handler outside the loop for better performance (doing less work)
$handler = static function () use ($app) {
    // Called when a request is received,
    // superglobals, php://input and the like are reset
    $response = $app->handle(\TYPO3\CMS\Core\Http\ServerRequestFactory::fromGlobals());
    $app->sendResponse($response);
};
for ($nbRequests = 0, $running = true; isset($_SERVER['MAX_REQUESTS']) && ($nbRequests < ((int)$_SERVER['MAX_REQUESTS'])) && $running; ++$nbRequests) {
    $running = \frankenphp_handle_request($handler);

    // What to do with the $app here?
    // $app->terminate();
    gc_collect_cycles();
}

// What to do with the $app here?
// $app->shutdown();

Here my questions:

• How to debug this? Like, getting actual error messages related to my worker script?
• Do i actually need terminate(); and shtudown(); to do something specific?
• In general, any idea what is going on here?

Here is my playground project: https://gitlab.knallimall.org/ochorocho/franky

Thank you. :-)

Is $_SERVER['MAX_REQUESTS'] actually set to something? I usually just hardcode a number as a default in case it isn't set, but in your code that is missing. So, it is probably being cast to a 0 since that is the default when casting null.

[ochorocho]

@withinboredom thanks, now it works.

Worker script now is set to FRANKENPHP_CONFIG="worker ./public/index.php"

index.php minimal example:

use Symfony\Component\HttpFoundation\Response;

ignore_user_abort(true);

$classLoader = require dirname(__DIR__).'/vendor/autoload.php';

// Handler outside the loop for better performance (doing less work)
$handler = static function () {
    echo new Response("Hello World!", 200);
};
for ($nbRequests = 0, $running = true; ($nbRequests < (10)) && $running; ++$nbRequests) {
    $running = \frankenphp_handle_request($handler);

    // What to do with the $app here?
    // $app->terminate();
    gc_collect_cycles();
}

When the worker script was set to public/worker.php for some reason it still called the public/index.php. No idea if this is intended. Was just wondering it this is expected behaviour.

Was just wondering it this is expected behaviour.

Heh, smells exactly like #100. I don't know if it is intended, but its been that way forever. I think its just that the (default) script and (worker) script have to be the same file.
