I suffered the same problem when I installed Laravel Homestead with HHVM. If you enter some random junk like sdfkjl into your routes file you'll get a blank page (however, if add a semi-colon sdfkjl; you get error output). The errors are being logged at /var/log/hhvm/error.log but they don't go to the browser, instead you just get a blank page. It appears this is intentional behavior for HHVM. It also appears Laravel tries to handle these but doesn't catch some of the fatals sent by HHVM. Thanks to clues from this github issue I decided to make some slight changes to Laravel's Foundation\Bootstrap\HandleExceptions.php to see if I could get it to catch all of these fatals:
First, update your /etc/hhvm/php.ini and add these settings:
hhvm.server.implicit_flush = true
hhvm.error_handling.call_user_handler_on_fatals = true
Before modifying a package source, let's remove the vendor\compiled.php with this artisan command:
$ php artisan clear-compiled
And let's set the environment sessons to array:
in your .env
SESSION_DRIVER=array
(You may also need to clear all the random-looking session files in storage/framework/sessions)
Now any changes we make to the Laravel package source will immediately reflect. Let's update a few things in the HandleExceptions class:
in vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/HandleExceptions.php
// **** Add this to hold fatal error
protected static $fatalError = null;
...
public function handleError($level, $message, $file = '', $line = 0, $context = array())
{
// **** Add this, loads fatal error
if ($level & (1 << 24)) {
self::$fatalError = array(
'message' => $message,
'type' => $level,
'file' => $file,
'line' => $line
);
}
if (error_reporting() & $level)
{
throw new ErrorException($message, 0, $level, $file, $line);
}
}
...
// *** Update this function so it can handle the fatal
public function handleShutdown()
{
$error = error_get_last();
if(self::$fatalError){
$error = self::$fatalError;
}
if ( ! is_null($error) && $this->isFatal($error['type']))
{
$this->handleException($this->fatalExceptionFromError($error, 0));
}
}
...
protected function isFatal($type)
{
// *** Add type 16777217 that HVVM returns for fatal
return in_array($type, [16777217, E_ERROR, E_CORE_ERROR, E_COMPILE_ERROR, E_PARSE]);
}
...
Now type the random junk (no semi-colon) in your routes folder and you'll see the fatal display. I have now reported this issue to Taylor on the Laravel github. If you are in Lumen, I've got a solution here that will work until Lumen gets fixed as well.
