[DoctrineBundle] Tries to auto-generate the missing proxy files on the autoloaded

See:
https://github.com/symfony/symfony/issues/1965
https://github.com/symfony/symfony/issues/1535

This fix is not really clean and there's maybe a factorizing work to do on it, but this work and avoid me spending my day deleting session cookies each time I clear cache.

You should follow Symfony2 CS (http://symfony.com/doc/current/contributing/code/standards.html).

It looks like a bug fix, so this PR should be closed and a new one based on the 2.0 branch should be open. @beberlei: are you fine with this patch?

---------------------------------------------------------------------------

What is this for? I dont understand the bug and the solution here screams cache slam.

---------------------------------------------------------------------------

by beberlei at 2011/09/29 04:34:02 -0700

Ok i get the problem but the solution is still a monsterous hack. Can we find a real solution to the problem? There has to be one.

@beberlei, when an user is authenticated for instance, there can be proxies serialized in session.

Si if you clear the cache in dev environment you'll get an error because the matching proxy classes won't exist and you'll be forced to clear your cookies and reauth, which can be annoying

---------------------------------------------------------------------------

by Gregwar at 2011/09/29 04:38:45 -0700

@beberlei, yes, I agree that we should do something more elegant, but the problem is that when PHP "meet" the proxy class we can't really know what was the "original" class it is supposed to extend

And as @schmittjoh said, this will only be executed very rarely

---------------------------------------------------------------------------

You agree you want something more suitable and still want this to be merged?

To ease the immediate pain wr could allow this however only in debug mode. A real solution here is maybe to move the proxy files out of the env folders. Rhey dont depend ont the env after all.

---------------------------------------------------------------------------

by stloyd at 2011/09/29 05:21:33 -0700

Proxy is not depending on env, but generation of proxy is... So this solution will be hard IMO, or even unacceptable...

---------------------------------------------------------------------------

by Gregwar at 2011/09/29 05:25:39 -0700

@beberlei what I meant is that I agree that's dirty but I don't think of anything better to solve this...

---------------------------------------------------------------------------

Even if the current patch is not the best solution, we should probably apply it to fix the problem and think about a better solution afterwards. Does it sound good for everybody?
