This circular reference cannot be detected by the compiler pass as we
don't check for method arguments there.
The Container itself already detects such circular references at runtime.
So this fix is about circular references that are not detected at
compile time, and are not even detected at runtime because the code that
would cause the detection is never run (generated after a return
statement.)
This PR was squashed before being merged into the master branch (closes#7890).

ProxyManager Bridge
As of @beberlei's suggestion, I re-implemented #7527 as a new bridge to avoid possible hidden dependencies.
Everything is like #7527 except that the new namespace (and possibly package/subtree split) `Symfony\Bridge\ProxyManager` is introduced

This PR introduces lazy services along the lines of zendframework/zf2#4146
It introduces an **OPTIONAL** dependency to [ProxyManager](https://github.com/Ocramius/ProxyManager) and transitively to [`"zendframework/zend-code": "2.*"`](https://github.com/zendframework/zf2/tree/master/library/Zend/Code).
## Lazy services: why? A comprehensive example
For those who don't know what this is about, here's an example.
Assuming you have a service class like following:
```php
class MySuperSlowClass
{
public function __construct()
{
// inject large object graph or do heavy computation
sleep(10);
}
public function doFoo()
{
echo 'Foo!';
}
}
```
The DIC will hang for 10 seconds when calling:
```php
$container->get('my_super_slow_class');
```
With this PR, this can be avoided, and the following call will return a proxy immediately.
```php
$container->getDefinitions('my_super_slow_class')->setLazy(true);
$service = $container->get('my_super_slow_class');
```
The 10 seconds wait time will be delayed until the object is actually used:
```php
$service->doFoo(); // wait 10 seconds, then 'Foo!'
```
A more extensive description of the functionality can be found [here](https://github.com/Ocramius/ProxyManager/blob/master/docs/lazy-loading-value-holder.md).
## When do we need it?
Lazy services can be used to optimize the dependency graph in cases like:
* Webservice endpoints
* Db connections
* Objects that cause I/O in general
* Large dependency graphs that are not always used
This could also help in reducing excessive service location usage as I've explained [here](http://ocramius.github.com/blog/zf2-and-symfony-service-proxies-with-doctrine-proxies/).
## Implementation quirks of this PR
There's a couple of quirks in the implementation:
* `Symfony\Component\DependencyInjection\CompilerBuilder#createService` is now public because of the limitations of PHP 5.3
* `Symfony\Component\DependencyInjection\Dumper\PhpDumper` now with extra mess!
* The proxies are dumped at the end of compiled containers, therefore the container class is not PSR compliant anymore

78e3710 ProxyManager Bridge
A service can now be marked as synchronized; when set, all method calls
involving this service will be called each time this service is set.
When in a scope, methods are also called to restore the previous version of the
service.
This PR was squashed before being merged into the master branch (closes#6846).

e271b17 Remove the string optimization since it causes no real performance gain but increases generation time of the dumped PHP Container
Discussion
----------
PhpDumper and large strings
When the PhpDumper is dealing with longer strings, the regular expression performed to optimize this can be quite a performance hog.
In our case sometimes the dumper takes more then 30 seconds if leaving this enabled. Disabling it will bring it back to sub-second speed.
This patch makes the optimization optional by passing in an additional container option.
---------------------------------------------------------------------------
by fabpot at 2012-08-25T16:57:29Z
I don't like adding yet another option for something that should "just works". It would be better to find a better way to optimise the strings for all cases.
---------------------------------------------------------------------------
by mazen at 2012-08-25T17:22:07Z
I never really tested how much of a runtime difference it incurs when either using the "optimized" version or the non optimized version, so:
Having an example at hand which generates stable results yields (in a non-debug environment with a booted container using either of the optimization methods):
Without optimized strings:
```

With Optimized Strings enabled
```

```
So the response times differ by around 0.8ms
Building the non-optimized container takes around 800ms
Building the optimized container takes 43 seconds
From my Point of View it would just be viable to remove the optimization (since it already incurred some issues fixed in 808088a3ca).
I do not see a way how to improve the regexps (but by all means I'm no regular expression guru)
---------------------------------------------------------------------------
by fabpot at 2012-08-30T07:12:55Z
I'm also for removing these optimizations. What others think?
---------------------------------------------------------------------------
by Baachi at 2012-08-30T07:54:53Z
I'm +1 for removing this feature.
The performance boost is to small.
