How to log ZF2 controller exceptions - error-handling

Question

I'm registering a Zend\Log instance for exceptions, I will need all system errors emailed in the end, now it's just goes to a file. However, it doesn't work in controllers, the exception gets displayed in the view (or not, depending on display_exceptions). I found this bug, no one seems to care about it much. So I need a workaround. Is there a way to make controllers not to eat my exceptions?
'service_manager' => array(
'factories' => array(
'Logger' => function ($sm) use ($sRootDir)
{
$log = new Zend\Log\Logger();
$writer = new Zend\Log\Writer\Stream($sRootDir . '/temp/license.log');
$log->addWriter($writer);
Zend\Log\Logger::registerErrorHandler($log);
Zend\Log\Logger::registerExceptionHandler($log);
return $log;
},
),

You can attach to the dispatch error event:
Module.php
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
/**
* Log any Uncaught Errors
*/
$sharedManager = $e->getApplication()->getEventManager()->getSharedManager();
$sm = $e->getApplication()->getServiceManager();
$sharedManager->attach('Zend\Mvc\Application', 'dispatch.error',
function($e) use ($sm) {
if ($e->getParam('exception')){
$sm->get('Logger')->crit($e->getParam('exception'));
}
}
);
}
An example service config for a simple logger
'factories' => array(
'Logger' => function($sm){
$logger = new \Zend\Log\Logger;
$writer = new \Zend\Log\Writer\Stream('./data/log/'.date('Y-m-d').'-error.log');
$logger->addWriter($writer);
return $logger;
},
// ...
);
You can also log all exceptions in the stack to get a better idea of what went wrong down the line, rather than only showing the last exception, which may not include much information.
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
/**
* Log any Uncaught Exceptions, including all Exceptions in the stack
*/
$sharedManager = $e->getApplication()->getEventManager()->getSharedManager();
$sm = $e->getApplication()->getServiceManager();
$sharedManager->attach('Zend\Mvc\Application', 'dispatch.error',
function($e) use ($sm) {
if ($e->getParam('exception')){
$ex = $e->getParam('exception');
do {
$sm->get('Logger')->crit(
sprintf(
"%s:%d %s (%d) [%s]\n",
$ex->getFile(),
$ex->getLine(),
$ex->getMessage(),
$ex->getCode(),
get_class($ex)
)
);
}
while($ex = $ex->getPrevious());
}
}
);
}
