This speeds up Travis CI builds to `~2 min` also makes vendor management
a lot easier.
Redesigned the WDT.
Removed the check for verbose and adjusted the style when the toolbar is on the top of the page.
Made the toolbar to show the version, memory usage, the state of security (both a abbreviation and an associate description) and number of DB requests and request time.
Updated with PHP logo (only the text).
[Form] Added all() method to the FormBuilder class

In order to perform some introspection on a FormBuilder instance,
we need to be able to get its children. Almost everything is accessible
in this class, but the children are not.

This PR adds a all() method to respect the current API (get(), remove(),
...).

[process] Added destructor to process to make sure handles are always closed in the right order.

[WIP] Fixed ACL handling of Doctrine proxies

Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: [![Build Status](https://secure.travis-ci.org/jalliot/symfony.png?branch=acl_proxies-2)](http://travis-ci.org/jalliot/symfony)
Fixes the following tickets: #3818, #2611, #2056, #2048, #2035 and probably others
Todo: Fix tests, update changelog

Hi,

As per @fabpot's request, here is #3818 ported to `master`.

> Here is a new attempt to fix all the issues related to Symfony ACL identities and Doctrine proxies.
> It only fixes the issue for Doctrine >=2.2 (older versions of Doctrine will still not work properly with ACL because `Doctrine\Common\Util\ClassUtils` didn't exist before and proxy naming strategy was not consistent between all Doctrine implementations (ORM/ODM/etc.)).

I'm -1 on adding a dependency on the Doctrine class.

The naming scheme was designed in a generic way, we should just copy the method.

@schmittjoh The ACL component requires Doctrine DBAL already (and as such Common) so I don't think this is really an issue at the moment. If (when?) the component is refactored to be decoupled from Doctrine, then maybe we will have to change that.
But I can also copy the class (where?) if you think it is better :)

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

by schmittjoh at 2012-04-09T01:01:27Z

I'd suggest ``Symfony\Component\Security\Core\Util\ClassUtils``.

@fabpot @schmittjoh It's done: I've backported the ClassUtils class and its tests from Doctrine Common into the Security component. Maybe this PR can be merged into 2.0 as well now, what do you think?

There seems to be a consensus that ACLs don’t (fully?) work with Doctrine < 2.2, i.e. in Symfony 2.0. Can it therefore be documented somewhere, typically on the main documentation page on the subject? http://symfony.com/doc/current/cookbook/security/acl.html

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

by jalliot at 2012-04-11T07:36:25Z

@oscherler You can make ACL work with Doctrine < 2.2 and without this patch if you use something like this code (note this is for ORM only but it can be adapted for ODM; it also assumes that your identifier can be retrieved with `getId()`):

``` php
<?php

use Doctrine\ORM\Proxy\Proxy;
use Symfony\Component\Acl\Domain\ObjectIdentity;

$domainObject = ... // some Doctrine entity (maybe a proxy...)

if ($domainObject instanceof Proxy) {
    $objectIdentity = new ObjectIdentity($domainObject->getId(), get_parent_class($domainObject));
} else {
    $objectIdentity = new ObjectIdentity($domainObject->getId(), get_class($domainObject));
}
```
It is ugly but it is the only way to get the correct identity for < 2.2. Never use `ObjectIdentity::fromDomainObject` with a proxy and without this patch!
The same applies to `UserSecurityIdentity`.

This should indeed be documented in the doc for 2.0. /cc @weaverryan

I just fixed the tests and squashed the commits.
I didn't write a test for `UserSecurityIdentity::fromAccount` and `fromToken` because I didn't really have time to look for a clean solution (without creating a full UserInterface implementation for instance...). Anyway the test for `ObjectIdentity::fromDomainObject` should be enough I guess...
Don't hesitate to add one if you think it is necessary. /cc @schmittjoh

@fabpot Apart from @beberlei approval to use MIT license, I think it is ready for merge.

[Routing] remove duplicated cache of compiled routes

The UrlGenerator caches compiled routes for generating URLs. But the Route class caches it's compiled route itself as long as it does not get modified. So compiled routes are cached twice which makes no sense in my opinion.
