public function WritableFileSystemValidator::checkPermissions in Automatic Updates 8.2

Checks that the file system is writable.

@todo It might make sense to use a more sophisticated method of testing writability than is_writable(), since it's not clear if that can return false negatives/positives due to things like SELinux, exotic file systems, and so forth.

Parameters

\Drupal\automatic_updates\Event\UpdateEvent $event: The event object.

File

src/Validator/WritableFileSystemValidator.php, line 61

      '@dir' => $this->appRoot,
    ]);
  }
