Core

• Added new class \Shopware\Core\Framework\Plugin\KernelPluginLoader\ComposerPluginLoader to load plugins from composer without database instead
• Deprecated class \Shopware\Core\Framework\Plugin\BundleConfigDumper, use \Shopware\Core\Framework\Plugin\BundleConfigGenerator instead

Upgrade Information

Added support for building administration without database

In some setups it's common that the application is built with two steps in a build and deploy phase. The build process doesn't have any database connection. Currently, Shopware needs to build the administration a database connection, to discover which plugins are active. To avoid that behaviour we have added a new ComposerPluginLoader which loads all information from the installed composer plugins.

To use the ComposerPluginLoader you have to create a file like bin/ci and setup the cli application with loader. There is an example:

#!/usr/bin/env php
<?php declare(strict_types=1);

use Composer\InstalledVersions;
use Shopware\Core\Framework\Plugin\KernelPluginLoader\ComposerPluginLoader;
use Shopware\Production\HttpKernel;
use Shopware\Production\Kernel;
use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Input\ArgvInput;
use Symfony\Component\Dotenv\Dotenv;
use Symfony\Component\ErrorHandler\Debug;

set_time_limit(0);

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

$envFile = __DIR__ . '/../.env';

if (class_exists(Dotenv::class) && is_readable($envFile) && !is_dir($envFile)) {
    (new Dotenv())->usePutenv()->load($envFile);
}

if (!isset($_SERVER['PROJECT_ROOT'])) {
    $_SERVER['PROJECT_ROOT'] = dirname(__DIR__);
}

$input = new ArgvInput();
$env = $input->getParameterOption(['--env', '-e'], $_SERVER['APP_ENV'] ?? 'prod', true);
$debug = ($_SERVER['APP_DEBUG'] ?? ($env !== 'prod')) && !$input->hasParameterOption('--no-debug', true);

if ($debug) {
    umask(0000);

    if (class_exists(Debug::class)) {
        Debug::enable();
    }
}

$pluginLoader = new ComposerPluginLoader($classLoader, null);

$kernel = new HttpKernel($env, $debug, $classLoader);
$kernel->setPluginLoader($pluginLoader);

$application = new Application($kernel->getKernel());
$application->run($input);

With the new file we can now dump the plugins for the administration without database with the command bin/ci bundle:dump
