[HttpKernel] Fix call to Memcached::set() once again

I originally fixed this in #3358, but it appears #3363 (which touched the same line) was merged soon after.
Fixed \SessionHandlerInterface in DbalSessionStorage
[HttpKernel] Remove the _controller since it is not a route parameter part of the url
Fix windows fs tests
Broaden timer tests limits
Properly skip memcached tests when no memcached server is present
Some \SessionHandlerInterface related documentation updates
[DoctrineBridge] Compiler pass for registering event listeners/subscribers

This was imported from DoctrineBundle (see: doctrine/DoctrineBundle#23), since it can be used by other Doctrine bundles, too. It utilizes the ContainerAwareEventManager from f15dde6c595b8d35151662a44b25a9b4a203a129.

[DoctrineBundle] fixed proxy loader memory leak

[![Build Status](https://secure.travis-ci.org/kriswallsmith/symfony.png?branch=doctrine/proxy-loader-fix)](http://travis-ci.org/kriswallsmith/symfony)

The hack for loading Doctrine proxy classes has an obscure memory leak, fixed here by @jjbohn.

## The Proof

Run this test case before and after this patch:

```php
<?php

namespace Kris\JunkBundle\Tests\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class DefaultControllerTest extends WebTestCase
{
    /**
     * @dataProvider asdf
     */
    public function testIndex()
    {
        $client = static::createClient();

        $crawler = $client->request('GET', '/hello/Fabien');

        $this->assertTrue($crawler->filter('html:contains("Hello Fabien")')->count() > 0);
    }

    public function asdf()
    {
        return array_fill(0, 500, array());
    }
}
```

Your test suite will use much less memory — 82% in this case.

IMHO this change warrants a comment inside a source code as somebody might actually try to remove the first by reference assign like stof said.

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

by lsmith77 at 2012-02-23T07:55:48Z

this autoloader sounds like something we also need in the ODM's?

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

by stof at 2012-02-23T08:23:17Z

@lsmith77 if you want to allow unserializing proxies without forcing to generate them before (which would be an issue in debug mode), yeah. But take care that each Doctrine bundle should use a different proxy namespace to allow doing the check (there was some issues for people using both the ORM and the mongo ODM because of this)

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

by lsmith77 at 2012-02-23T08:24:33Z

then maybe this could should be a static method inside the bridge?

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

by beberlei at 2012-02-23T11:50:08Z

I think another side of this problem is that ->boot() ALWAYS adds this method on the autoloading stack. So with N tests you have N more autoloaders on the stack.

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

by pminnieur at 2012-02-23T12:07:00Z

This could be an issue if you use Symfony with Leach as an application server, too. After a while, memory is exhausted in face of `gc_collect_cycles` and `$kernel->boot()` and `$kernel->shutdown()` calls in between each request - which ultimately leads to a segfault after some time. I tried to track down what causes increasing memory usage and I think this could be the error.

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

by beberlei at 2012-02-23T12:28:06Z

its definately the problem, we need to remove the autoloader in shutdown, or move it elsewhere.

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

by lsmith77 at 2012-02-23T14:58:37Z

why isnt this just a setup task for the autoloader just like the annotation registry?

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

by stof at 2012-02-23T16:52:42Z

@lsmith77 because the proxy namespace and the proxy dir are not known in the autoload.php file. They are configured in the config files

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

by fabpot at 2012-02-23T18:05:51Z

The `shutdown()` method is where the autoloader should be removed. Can we include this in this PR as well so that we fix everything once and for all?

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

by kriswallsmith at 2012-02-23T19:12:05Z

The once and for all solution is for the Doctrine O*M projects to provide a ProxyLoader class with register and unregister methods that we call in boot and shutdown. We're not solving anything specific to Symfony here.

Fix tests

- Some windows fixes
- Skip memcached for real when it's not there - by the way I think those tests are insane since they seem to run a purge() on the memcached server. If you run this by accident somewhere where it matters it could hurt. I think they should be put in a group disabled by default, I'll be happy to add that change if it's deemed useful.
- Fixed the timer tests for good on windows (which seems to be quite bad at `usleep`). I also documented them so you actually know how it failed when it does, the false instead of true wasn't super useful.

[Finder] not searching in multiple dirs with sorting

I hit on a problem with **Finder, when using array of directories passed to ->in() together with sorting** (e.g. ->sortByName()):

*Catchable Fatal Error: Argument 1 passed to AppendIterator::append() must implement interface Iterator, instance of Symfony\Component\Finder\Iterator\SortableIterator given in ......\vendor\symfony\src\Symfony\Component\Finder\Finder.php line 421*

The problem is in Finder.php, line 419. When more than 1 directory is used, \AppendIterator is used to merge iterators for each directory. AppendIterator->append() accepts only objects implementing Iterator interface. But this is broken for SortableIterator, which implements IteratorAggregate and NOT Iterator.

My proposed solution retrieves an Iterator from IteratorAggregate, which is later valid as an input to AppendIterator->append()

(This solved the exception mentioned aboved in my testing project, not tested more.)
