TYPO3 Core

In my schema extension I injected a frontend cache with DI into a class.

The cache is defined in the ext_localconf.php:

    $coreCacheIdentifier = 'tx_' . $extensionKey . '_core';
    if (!is_array($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier])) {
        $GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier] = [];
    }
    if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier]['frontend'])) {
        $GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier]['frontend'] = \TYPO3\CMS\Core\Cache\Frontend\PhpFrontend::class;
    }
    if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier]['backend'])) {
        $GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier]['backend'] = \TYPO3\CMS\Core\Cache\Backend\SimpleFileBackend::class;
    }
    if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier]['options'])) {
        $GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations'][$coreCacheIdentifier]['options']['defaultLifetime'] = 0;
    }

and listed correctly in the Configuration module.

Definition in Services.yaml:

services:
  cache.tx_schema_core:
    class: TYPO3\CMS\Core\Cache\Frontend\FrontendInterface
    factory: ['@TYPO3\CMS\Core\Cache\CacheManager', 'getCache']
    arguments: ['tx_schema_core']

  Brotkrueml\Schema\Registry\TypeRegistry:
    arguments:
      $cache: '@cache.tx_schema_core'
      $packageManager: '@TYPO3\CMS\Core\Package\PackageManager'

In the TypeRegistry class itself, the the constructor looks like:

public function __construct(FrontendInterface $cache = null, PackageManager $packageManager = null)

The injection works for most cases in frontend and backend. However, executing two routines in the Upgrade module fail:

- Check TCA in ext_tables.php
- Check TCA Migrations

But: When I define the cache in the AdditionalConfiguration.php instead of localconf.php it works. Also when deactivating DI in Services.yaml

The behaviour can be reproduced with the schema extension (commit af18687d from April 5th):
