Calling Debug::enable() disables var-dumper support in WebProfiler.

[jlayt]

Calling Debug::enable() disables the var-dumper support in WebProfiler. This is due to the following code in WebProfileServiceProvider:

$app['profiler.templates_path.debug'] = function () {
    foreach (spl_autoload_functions() as $autoloader) {
        if (!is_array($autoloader) || !method_exists($autoloader[0], 'findFile')) {
            continue;
        }
        if ($file = $autoloader[0]->findFile('Symfony\Bundle\DebugBundle\DebugBundle')) {
            return dirname($file).'/Resources/views';
        }
    }
};

Calling Debug::enable() replaces the autoloader with DebugClassLoader which lacks a findFile() method, so the template is never found and the data collector never added, kind-of defeating the whole purpose!

I have the same issue.

[jlayt]

A slightly hacky workaround in the WebProfileServiceProvider class is to change the above code to be:

$app['profiler.templates_path.debug'] = function () {
    foreach (spl_autoload_functions() as $autoloader) {
        if (!is_array($autoloader) || !is_array($autoloader[0]->getClassLoader()) || !method_exists($autoloader[0]->getClassLoader()[0], 'findFile')) {
            continue;
        }

        if ($file = $autoloader[0]->getClassLoader()[0]->findFile('Symfony\Bundle\DebugBundle\DebugBundle')) {
           return dirname($file).'/Resources/views';
        }
    }
};

The real fix should be in DebugClassLoader though.

Why not use reflection here, like is done for the other paths?

$app['profiler.templates_path.debug'] = function () {
    $r = new \ReflectionClass(DebugBundle::class);
    return dirname($r->getFileName()).'/Resources/views';
};

[jlayt]

Nice idea, just tried it, but DebugBundle extends Bundle which requires Symfony\Component\DependencyInjection to be installed, which normally isn't for Silex, so the reflection throws an exception. The best fix is for DebugClassLoader to get a findFile method. Ideally the twig would actually live in the Debug component instead, but that would probably break stuff.

Thanks @jlayt, I thought there might be something I was missing :smile:

[jlayt]

A far neater workaround, doing it exactly the same way as 'profiler.templates_path' gets set:

$this['profiler.templates_path.debug'] = function () {
    $r = new \ReflectionClass('Symfony\Bundle\DebugBundle\DependencyInjection\Configuration');
    return dirname(dirname($r->getFileName())).'/Resources/views';
};

@jlayt Wouldn't that require ConfigurationInterface from symfony/config (which is not a required dependency)?

Hi, I have the same issue. But the panel "Debug" is loaded if the debug bundle is installed "symfony/debug-bundle".

But, the panel is empty. How to work ?

[Mingun]

After about a five hours digging a code I made it works. For this need doing some steps:

1. Adding to project package symfony/debug-bundle:

   composer require symfony/debug-bundle --dev

   This is need for template files for Debug panel. No other resources from it not using, only templates from vendor\symfony\debug-bundle\Resources\views\Profiler.

2. As @jlayt says, in file vendor\silex\web-profiler\Silex\Provider\WebProfilerServiceProvider.php need change defining service 'profiler.templates_path.debug' to either the same way as 'profiler.templates_path' (need installed package symfony/config thought):

      $app['profiler.templates_path.debug'] = function () {
          $r = new \ReflectionClass('Symfony\Bundle\DebugBundle\DependencyInjection\Configuration');
   
          return dirname(dirname($r->getFileName())).'/Resources/views';
      };

   or tuning current implementation:

      $app['profiler.templates_path.debug'] = function () {
           // This code cannot be simplified as all classes in the bundle depend
           // on packages that are not required by Silex
           foreach (spl_autoload_functions() as $autoloader) {
               if (!is_array($autoloader) || !is_array($autoloader[0]->getClassLoader()) || !method_exists($autoloader[0]->getClassLoader()[0], 'findFile')) {
                   continue;
               }
   
               if ($file = $autoloader[0]->getClassLoader()[0]->findFile('Symfony\Bundle\DebugBundle\DebugBundle')) {
                   return dirname($file).'/Resources/views';
               }
           }
      };

   This is need for find template files from step 1. Now Debug panel appears in Web Profiler, but it always empty. So we need step 3:

3. In file vendor\symfony\http-kernel\EventListener\DumpListener.php change method getSubscribedEvents() to this:

   use Symfony\Component\HttpKernel\KernelEvents;
   
   // ...
   
      public static function getSubscribedEvents()
      {
          // Register early to have a working dump() as early as possible
          $events = array(KernelEvents::REQUEST => array('configure', 1024));
          if (class_exists(ConsoleEvents::class)) {
              $events[ConsoleEvents::COMMAND] = array('configure', 1024);
          }
   
          return $events;
      }

   We added listener to event KernelEvents::REQUEST. Now dumps will be appears in Debug panel. Global function dump() will refer to service 'var_dumper.data_collector', which doing all work.

Note, that dumps from twig templates do not appear in Debug panel, because they working directly through HtmlDumper.

Yes, this is ugly hack but it works... for a while.
