c195957 [Components] Tests/Autoloading fixes
Discussion
----------
Fix components
See #4141
----
This PR:
* configures each component to use composer to manage "dev" dependencies instead of env variables;
* adds phpunit configuration file on Filesystem component;
* fixes READMEs.
It's mergeable without any problems, but I would recommend to wait a fix in Composer in order to use `self.version` in `require`/`require-dev` sections.
Note: I kept `suggest` sections because it makes sense but this PR doesn't aim to provide useful explanations for each entry. It could be another PR, not that one.

@fabpot I reviewed each component, one by one. Now `phpunit` always works, even if tests are skipped. A simple `composer install --dev` allows to run the complete test suite. Each commit is well separated from the others. I guess, everything is ok now.

Please squash, as it makes no sense to have the same commit for each component.

Please implement a XcacheClassLoader following the same pattern than the new ApcClassLoader instead

- should include tests
- should include documentation (will you also update the component documentation for this new class?)
---------------------------------------------------------------------------
by stof at 2012-04-07T14:25:00Z
@cordoval the PR explains why there is no tests: xcache canot be used in the CLI.

ok @stof sorry it said it seemed not to be possible, i thought it was possible but I am wrong.

@cordoval My english is really horrible. I would not mind if someone else could do that task for me. We also need to add doc for the new ApcClassLoader.
---------------------------------------------------------------------------
by cordoval at 2012-04-07T15:03:57Z
I wish you can explain me more then about this class and how to use it in code so then I can write easily the documentation :D deal?
---------------------------------------------------------------------------
by kimhemsoe at 2012-04-07T15:21:25Z
Deal :P
The XcacheClassLoader and ApcClassLoader replaces the old ApcUniversalClassLoader.
They giving us support for using another loader then UniversalClassLoader, without duplicating the cache layer.
Aslong it have a public function findFile($class) method.
$loader = new ClassLoader();
// register classes with namespaces
$loader->add('Symfony\Component', __DIR__.'/component');
$loader->add('Symfony', __DIR__.'/framework');
$cachedLoader = new XcacheClassLoader('my_prefix', $loader);
// activate the cached autoloader
$cachedLoader->register();
Think that is more or less the essence of this.
---------------------------------------------------------------------------
by cordoval at 2012-04-09T08:28:53Z
it is not add but registerNamespace right?
so the main idea is to get rid of the restriction to use Apc with Universal loader
what is the comparative advantage between APC and Xcache?
---------------------------------------------------------------------------
by kimhemsoe at 2012-04-09T08:55:23Z
Yes if the $loader (class finder) were to be a instance UniversalClassLoader.
Yes the main idea is to be able to reuse the cache layer with any class loader there obey to the one restriction.
Difference between apc and xcache and why to use what is coming down to taste and your setup. We use xcache as APC have some issues in fastcgi setups. when we upgrade to php54 at somepoint we get to chance to move to php-fpm wich solves these issues. Short story: Slightly out of scope for any documentation in here :-P

Autoloader refactoring
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: [](http://travis-ci.org/stof/symfony)
As discussed in #3623, I added a new ClassLoader instead of modifying the UniversalClassLoader, to be able to use the method names without BC concerns. The new class works the same than the composer autoloader regarding the handling of fallbacks, to be able to reuse namespace maps generated by composer.
```php
<?php
// autoload.php
require_once __DIR__.'/vendor/symfony/class-loader/Symfony/Component/ClassLoader/ClassLoader.php';
$loader = new Symfony\Component\ClassLoader\ClassLoader();
$map = require __DIR__.'/vendor/.composer/autoload_namespaces.php';
$loader->addPrefixes($map);
$loader->register();
```
Differences with the composer class loader:
- Composer's ``add`` method is named ``addPrefix`` in the Symfony ClassLoader
- the methods related to the class map are removed as Symfony has a separate laoder for class maps
- the ``addPrefixes`` method is added, accepting a namespace map.
I also added a new ApcClassLoader which uses composition instead of inheriting from a class loader, which makes it far more easier to reuse (we could wrap a Composer autoloader with it for instance).
```php
<?php
$composerLoader = require __DIR__.'/vendor/.composer/autoload.php';
// no need to require the file manually as Composer already registered its autoloader
$cachedLoader = new Symfony\Component\ClassLoader\ApcClassLoader('autoload.my_app', $composerLoader);
$cachedLoader->register();
// unregister the Composer autoloader as we wrapped it in the ApcClassLoader
$composerLoader->unregister();
```
TODO:
- refactor the Debug class loader to use composition too to be able to support different class loaders
---------------------------------------------------------------------------
by fabpot at 2012-04-02T16:31:28Z
Can you update the CHANGELOG and the UPGRADE file accordingly?
---------------------------------------------------------------------------
by stof at 2012-04-02T16:47:43Z
I added a note in the CHANGELOG. There is nothing to add in the UPGRADE file as the change is fully BC (I did not change the UniversalClassLoader at all so it can still be used).
I'm working on the Debug loader right now so please wait a bit before merging
---------------------------------------------------------------------------
by stof at 2012-04-02T17:12:11Z
Here is a new DebugClassLoader using composition too. this way, it is able to support the UniversalClassLoader, the ApcUniversalClassLoader (without dropping the use of APC as done previously), the new ClassLoader, the new ApcClassLoader and even the composer autoloader.
I'm not sure about the use of ``method_exists`` as it could break if an autoloader implements a protected ``findFile`` method (crappy PHP 😢) but hardcoding the supported classes would be a pain and requiring an interface would make the autoloaders more difficult to use (as the interface would need to be required first) and would drop the support of the composer autoloader.
Unlike the ApcUniversalClassLoader, ApcClassLoader uses composition,
meaning it can be used to wrap any object providing a findFile($class)
method. Both the UniversalClassLoader and the new ClassLoader follow
this convention. It can also be used to wrap the Composer autoloader.
The new ClassLoader does not differentiate namespaced classes and
PEAR-like classes like the UniversalClassLoader does as the PEAR
format is a subset of PSR-0.
The new loader registers fallbacks by adding a location for an empty
prefix, as done in Composer. This allows using namespaces map generated
by Composer without any special processing on them.
fixed cs
Small refactoring for Finder support
If class name found, return
Find multiple classes and namespaces in the same file
fixed problems with inheritance and non-php files
Renamed ClassMapDumper to ClassMapGenerator

Great work. For syntax highlighting on the PHP snippets, you could add "php" after the three backticks.

Nice job, but you also need to add `<?php`
ex :
``` php
<?php
use Symfony\Component\DomCrawler\Crawler;
$crawler = new Crawler();
$crawler->addContent('<html><body><p>Hello World!</p></body></html>');
print $crawler->filter('body > p')->text();
```

@lsmith77 Well done! This makes consumption of individual components that much easier, *especially* now that `composer.json` files have been added.

ok .. fixed the issues you mentioned @fabpot
---------------------------------------------------------------------------
by lsmith77 at 2011/11/11 15:00:27 -0800
@fabpot anything else left? seems like an easy merge .. and imho there is considerable benefit for our efforts to spread the word about the components with this PR merged.
---------------------------------------------------------------------------
by drak at 2011/11/11 18:54:13 -0800
You know, it might be a nice idea to put a link to the documentation for each component if there is some at symfony.com
---------------------------------------------------------------------------
by lsmith77 at 2011/11/12 00:59:14 -0800
i did that in some. but i might have missed a few places.

@fabpot: seriously .. if you are not going to deliver something "better" and don't provide a reason what is wrong with this .. then its beyond frustrating. i obviously do not claim that these README's are perfect (and certainly still no replacement for proper documentation), but I do claim that in their current form they are a radical step forward to potential users of the Symfony2 components.

And squashed.
A class in Symfony2 can be loaded by four different mechanisms:
* bootstrap.php: This file contains classes that are always required and
needed very early in the request handling;
* classes.php: This file contains classes that are always required and
managed by extensions via addClassesToCompile();
* MapFileClassLoader: This autoloader uses a map of class/file to load
classes (classes are managed by extensions via addClassesToAutoloadMap(),
and should contain often used classes);
* UniversalAutolaoder: This autoloader loads all other classes (it's the
slowest one).
