Setting up php-sdk-gae with symfony2

Question

I'm trying to run symfony2 with a hello world sample bundle inside php-sdk-gae.

I'm following the instructions provided in https://developers.google.com/appengine/docs/php/ and I can run the demo with the development controller (i.e: configuring app.yaml as following:

application: helloworld
version: 1
runtime: php
api_version: 1

handlers:
- url: /bundles
  static_dir: helloWorld/web/bundles

- url: /favicon.ico
  static_files: helloWorld/web/favicon.ico
  upload: helloWorld/web/favicon.ico

- url: /.*
  script: helloWorld/web/app_dev.php

It works fine, and I am able to get a Hello World after running the server and load /hello/World page

But when I try to run it with the production controller (app.php instead app_dev.php), I get an internal server error.

Request URL:http://mysite.local:8080/hello/World
Request Method:GET
Status Code:500 Internal Server Error

The only clue is in the console window where I launched the server, showing the lines ...

ERROR:root:php failure (255) with:
Status: 500 Internal Server Error
X-Powered-By: PHP/5.4.15
Content-type: text/html

If I make some changes in app.php files, I realize that it works fine with following AppKernel loading lines:

$kernel = new AppKernel('prod', true);
$kernel = new AppKernel('dev', false);
$kernel = new AppKernel('dev', true);

But not with the default configuration for the production enviroment ('prod',false).

I'm launching GAE server with this command: google_appengine/dev_appserver.py --php_executable_path=/home/jon/php-sdk-gae/php-5.4.15/installdir/bin/php-cgi helloWorld/

I'm new in GAE, and I wonder Where can I find logs to get some more information about this error.

There is an uncaught exception in your production environment. Thats the reason for the http 500 error.

Let me quickly explain AppKernel::__construct

$kernel = new AppKernel($environment, $debug);

The first argument is the environment , the second one is the debug option.

If you set debug to true , symfony will try to catch exceptions and show you a nice stracktrace.

This covers the first and the third case where you don't get the http 500 error ( caused by an uncaught exception ).

$kernel = new AppKernel('prod', true);
$kernel = new AppKernel('dev', true);

Now you state the error is NOT thrown in dev environment with debug set to false.

$kernel = new AppKernel('dev', false);

This means in dev environment there is no exception.

Now you have to check the production log file to find out which exception has been thrown.

Use tail -f to see the live changes made to that file in your shell ( i.e. bash ) or if not available open the file in your editor and look for exceptions at the end.

tail -f app/logs/prod.log 

In the symfony2 standard edition logfiles can be found at

app/logs/%kernel.environment%.log  

... with %kernel.environment% being one of dev/prod/test

The problem is related with .htaccess file shipped with Symfony 2.2

I can use without any problem an application in symfony 2.0, and my application with Symfony 2.2 also works if I replace the web/.htaccess file shipped with Symfony 2.2 with the one shipped with Symfony 2.0

Maybe it is something related with the change made in order to avoid duplicate content (/app.php/something and /something), because since Symfony 2.2, /app.php redirects (301) the request.
