Because the name of the kernel is calculated in the constructor,
any child class that had overriden the kernel name, will be
ignored.
By setting the kernel name in the child class, we can avoid having
to execute the regex to calculate the name upon every construction
of a Kernel.
A test (and a kernel fixture) is added to prove that the override
works correctly.
Note: the Kernel API has not been touched, so there should be no
issues with BC.

[Component][HttpKernel] fixed testGetRootDir() on Win
Bug fix: yes

Backwards compatibility break: no
Symfony2 tests pass: [](http://travis-ci.org/gajdaw/symfony)
Fixes the following tickets: -
Todo: -
License of the code: MIT
Documentation PR: -
Method `getRootDir()` returns path containing slashes. On Windows machine `__DIR__` and `DIRECTORY_SEPARATOR` are backslashes. To pass the test on win machine we have to translate `\` into `/`.
The charset was configurable in a configuration file but it never worked:
framework:
charset: ISO-8859-1
Now, like for the cache and log dirs, you can configure the charset by
overriding the getCharset() method in the app kernel:
public function getCharset()
{
return 'ISO-8859-1';

88caf3a [HttpKernel] removed the storage of the current locale in the session
Discussion

[HttpKernel] removed the storage of the current locale in the session
Before this commit, the current locale was stored in the session (if one
was already started). That way, for the next requests, even if the
request locale attribute was not set, the locale was "restored".
But this is a really bad practice as it means that the same URL can have
a different content depending on the previous requests. It would have
been better if the Vary header was set but the locale can be different
from the value coming from the Accept-Language anyway.
This is a BC break but fortunately, you can restore the 2.0 behavior by
creating a simple event listener that contains the logic removed by this
commit.

The goal is to make Symfony as stateless as possible; introducing a cookie would defeat this goal.
---------------------------------------------------------------------------
by drak at 2012-07-01T09:19:37Z
@fabpot - thank you for bringing this to attention. I was meaning to do it a long time ago. The requested language is entirely a per request issue and must always be so. URLs must only ever return one content, and not multiple (e.g. different languages). The correct way to behave is to detect the language based on URL and failing that where a language is not requested, to look at the preferred language from the browser request and if available it can be redirected to that resource (e.g. /fr). This is what we do in Zikula. We have a further session based setting for "preferred language" which if set will override the browser default.
In summary:
1. If the language is specified in the GET request, return that language always. E.g. domain.com/fr/foo should return a French version of foo
2. If no language is specified in the GET request: first check the session for a preferred language, otherwise check the browser string for the preferred language and then if necessary, redirect to that resource. We have a setting which additionally say "always have language in URL, and don't put language code in URL for default language"
This means what in Zikula we only ever have one URL per language version of a page, but it still allows for users to set their preferred language which is taken in to account mainly when they visit the homepage (but in fact any page without a specific language in the request).
---------------------------------------------------------------------------
by drak at 2012-07-01T09:38:06Z
+1 on this PR. Basically the request locale should be in the Request object and calculated according to the applications preferences.
---------------------------------------------------------------------------
by schmittjoh at 2012-07-01T12:38:25Z
I agree that content must be detected based on the request, but I strongly disagree with relying entirely on the URL.
@fabpot, if you think about it using a cookie would still be stateless. There would be no state whatsoever, the detection would be entirely based on the request. Whether the language information is transmitted in the URL or as part of request headers is for the developer to decide eventually, at least IMO. My suggestion would just provide a default which is more BC.
---------------------------------------------------------------------------
by drak at 2012-07-01T20:08:50Z
@schmittjoh it's not entirely from the URL, there are browser preferences and also user defaults ca nalso available but the latter is slightly higher level. IMO it's not really Symfony's job here, it's application level specific. We have a pretty good working example of that in Zikula. Anyone can easily implement your own requirements with a listener.
What is absolutely clear however is it is wrong for one URL to deliver more than one version of any content.
---------------------------------------------------------------------------
by schmittjoh at 2012-07-01T21:16:52Z
I'm 100% for this change. My suggestion would just be more BC while still keeping Symfony2 stateless. Of course, it can be easily implemented in userland if we do not care about BC here.
Regarding different URLs per content, I do not think that this is our decision to make. Generally, developers should be able to make whatever content negotation they see fit. Whether they rely solely on the URL, or also take other request headers into account should not be limited by Symfony2.
---------------------------------------------------------------------------
by fabpot at 2012-07-02T10:37:26Z
I've added a paragraph in the UPGRADE file with a listener example that can be used to keep BC.
Before this commit, the current locale was stored in the session (if one
was already started). That way, for the next requests, even if the
request locale attribute was not set, the locale was "restored".
But this is a really bad practice as it means that the same URL can have

Thanks for the help, looks like I forgot the -f when pushing. It should be okay now
- Missing dependency in one file
- Move helper class out of KernelTest because it implemented an
interface that depends on another component (thus would crash the
testsuite if invoked)
The listener does not depend on the RouterInterface but only on the
RequestContextAwareInterface which is also implemented by the matcher
and the generator. Changing the typehint allow reusing the listener

46be121 added tokenDataExists() method to prevent loading complete profile structures upon writes
Discussion
----------
[HttpKernel] prevent loading complete profile structures upon writes
The abstract class "PdoProfilerStorage" uses its ::read() method to decide if a profiler record has to be updated or initially created upon a ::write() call. This possibly causes huge memory consumption, as ::read() recursively reads all existing profiles using ::createProfileFromData() calls. When handling many sub-request this may lead into either a "out of memory" or XDebug's "maximum nesting level reached" - whichever comes first.
To prevent this issue, I added a new protected method ::tokenDataExists() that simply checks whether a record for the token in question already exists in storage.

[HttpKernel] Enhance FlattenException to include more methods from Exception.
I'm trying to retrofit FlattenException into Drupal, in places where Drupal expects an Exception. That doesn't quite work though, as FlattenException only has some of the methods from Exception. I'm not entirely clear why it only has some, but this PR adds getFile() and getLine() so that it's a more ready drop-in. I did not add them to the toArray() method for fear of breaking BC somewhere, but that could be done as well no doubt if folks felt it was appropriate.
Note: While the parts of Drupal in question will get rewritten later anyway, I think having this information exposed is a good thing in general for logging purposes if nothing else. It's already possible to dig it out of the trace, so this is just an improved "Developer eXperience" (DX).
---------------------------------------------------------------------------
by fabpot at 2012-04-20T04:34:54Z
I'm +1 to make `FlattenException` more "compatible" with `Exception`. Can you add the other missing methods? Also, you need to populate the `$this->file` and `$this->line` value in the constructor.

by Crell at 2012-04-20T04:48:40Z
I knew I was forgetting something obvious...
According to http://us.php.net/manual/en/class.exception.php, I think the only other missing method is http://us.php.net/manual/en/exception.gettraceasstring.php. I'm not sure how useful that is, but I can try to approximate it if you think it's necessary. (Honestly I've never used that method on an exception myself.)
I should probably add some tests, too. Stand by for those.

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();
```

---------------------------------------------------------------------------
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.

[WIP] Refactored profiler tests including some storage fixes
Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
While refactoring the tests I came across some inconsistencies. Two of them are already fixed in this PR.
One thing left is the [MongoDbProfilerStorageTest::testCleanup()](9d8e3f2da4/tests/Symfony/Tests/Component/HttpKernel/Profiler/MongoDbProfilerStorageTest.php (L51)) test which fails in all other storage implementations. The mongodb implementation uses the `time` value from the profiler data to clean up the storage while the others additionally save a `created_at` value which is then used. For me this `created_at` value does not make any sense and I would suggest to change the other implementations to use the `time` value for cleaning up. What do you think?

I am just starting with git. Could you please add some tutorial about squash to a documentation page: http://symfony.com/doc/2.0/contributing/code/patches.html ? It will help me (and maybe some others) to do it correct way.

Hi,
Would it be possible to either use Memcached instead of Memcache or make it configurable to use either Memcache or Memcached?
I've did a little digging on the benefits of using Memcached over Memcache (like for example: http://stackoverflow.com/questions/1442411/using-memcache-vs-memcached-with-phphttp://devzone.zend.com/1869/zendcon-sessions-episode-040-memcached-the-better-memcache-interface/ ) and maybe this will also help in not having two extensions installed for people who are using Memcached already.
Regards.

@dlsniper thanks for great comment. I will add memcached support.

@pulzarraider what is the status of this PR ? Is it still a WIP ?
---------------------------------------------------------------------------
by pulzarraider at 2011-12-12T22:58:48Z
@stof Yes, it's still WIP. I'm working on a memcached (with D at the end) support. It will be finished in the next few days.

While first commits were focused on problem solving, the last brings a clean API with the ability to re-open an existing section in order to add events (re-setting event origins and merging them were just hacks).
Should be ready to be merged.
_Edit: Sorry, couldn't resist adding a private helper class again!_
---------------------------------------------------------------------------
by stof at 2012-02-06T18:30:09Z
@vicb you should stop adding such classes defined in the same file. Otherwise we will have to change the CS (and to stop telling we respect the PSR-0 standard)
---------------------------------------------------------------------------
by vicb at 2012-02-06T18:33:36Z
Once again PSR-0 is about autoloading which is exactly why I do not want in such cases. CS are an other matter and yes I think they should be changed to allow this (and I am going to submit a PR right now).
The only argument I could accept is whether this class should be private or not.

How faster ? even if the string is long and do not contain an occurrence of the sub-string ?
Looks like micro-(not)-optimizations to me.
---------------------------------------------------------------------------
by kriswallsmith at 2012-01-11T20:04:26Z
The difference is about 0.1s when repeated 1M times.
---------------------------------------------------------------------------
by vicb at 2012-01-11T20:08:12Z
% would be better (machine & env independant), what string size, what match offset ?
I personally vote against (`substr` is more meaningful to me and I do not like micro-optims)

I personally consider this a coding standard but don't want to bikeshed here :)

I have [tried](https://gist.github.com/1596588) at home.
`strpos ` **is** faster unless you have a very long string, probably because you do not need to create a new string, interesting, thanks for the tip.
---------------------------------------------------------------------------
by Tobion at 2012-01-11T22:40:18Z
I think strpos() is more useful. Say you want to change the string you have to replace 2 variables (the text and the length parameter) when using substr(). It could also introduce bugs when they don't match. With strpos() it's only the text.

[HttpFoundation] added support for streamed responses
To stream a Response, use the StreamedResponse class instead of the
standard Response class:
$response = new StreamedResponse(function () {
echo 'FOO';
});
$response = new StreamedResponse(function () {
echo 'FOO';
}, 200, array('Content-Type' => 'text/plain'));
As you can see, a StreamedResponse instance takes a PHP callback instead of
a string for the Response content. It's up to the developer to stream the
response content from the callback with standard PHP functions like echo.
You can also use flush() if needed.
From a controller, do something like this:
$twig = $this->get('templating');
return new StreamedResponse(function () use ($templating) {
$templating->stream('BlogBundle:Annot:streamed.html.twig');
}, 200, array('Content-Type' => 'text/html'));
If you are using the base controller, you can use the stream() method instead:
return $this->stream('BlogBundle:Annot:streamed.html.twig');
You can stream an existing file by using the PHP built-in readfile() function:
new StreamedResponse(function () use ($file) {
readfile($file);
}, 200, array('Content-Type' => 'image/png');
Read http://php.net/flush for more information about output buffering in PHP.
Note that you should do your best to move all expensive operations to
be "activated/evaluated/called" during template evaluation.
Templates
---------
If you are using Twig as a template engine, everything should work as
usual, even if are using template inheritance!
However, note that streaming is not supported for PHP templates. Support
is impossible by design (as the layout is rendered after the main content).
Exceptions
----------
Exceptions thrown during rendering will be rendered as usual except that
some content might have been rendered already.
Limitations
-----------
As the getContent() method always returns false for streamed Responses, some
event listeners won't work at all:
* Web debug toolbar is not available for such Responses (but the profiler works fine);
* ESI is not supported.
Also note that streamed responses cannot benefit from HTTP caching for obvious
reasons.
---------------------------------------------------------------------------
by Seldaek at 2011/12/21 06:34:13 -0800
Just an idea: what about exposing flush() to twig? Possibly in a way that it will not call it if the template is not streaming. That way you could always add a flush() after your </head> tag to make sure that goes out as fast as possible, but it wouldn't mess with non-streamed responses. Although it appears flush() doesn't affect output buffers, so I guess it doesn't need anything special.
When you say "ESI is not supported.", that means only the AppCache right? I don't see why this would affect Varnish, but then again as far as I know Varnish will buffer if ESI is used so the benefit of streaming there is non-existent.
---------------------------------------------------------------------------
by cordoval at 2011/12/21 08:04:21 -0800
wonder what the use case is for streaming a response, very interesting.
---------------------------------------------------------------------------
by johnkary at 2011/12/21 08:19:48 -0800
@cordoval Common use cases are present fairly well by this RailsCast video: http://railscasts.com/episodes/266-http-streaming
Essentially it allows faster fetching of web assets (JS, CSS, etc) located in the <head></head>, allowing those assets to be fetched as soon as possible before the remainder of the content body is computed and sent to the browser. The end goal is to improve page load speed.
There are other uses cases too like making large body content available quickly to the service consuming it. Think if you were monitoring a live feed of JSON data of newest Twitter comments.

How does this relate the limitations mentioned in:
http://yehudakatz.com/2010/09/07/automatic-flushing-the-rails-3-1-plan/
Am I right to understand that due to how twig works we are not really streaming the content pieces when we call render(), but instead the entire template with its layout is rendered and only then will we flush? or does it mean that the render call will work its way to the top level layout template and form then on it can send the content until it hits another block, which it then first renders before it continues to send the data?
---------------------------------------------------------------------------
by stof at 2011/12/21 09:02:53 -0800
@lsmith77 this is why the ``stream`` method calls ``display`` in Twig instead of ``render``. ``display`` uses echo to print the output of the template line by line (and blocks are simply method calls in the middle). Look at your compiled templates to see it (the ``doDisplay`` method)
Rendering a template with Twig simply use an output buffer around the rendering.
---------------------------------------------------------------------------
by fabpot at 2011/12/21 09:24:33 -0800
@lsmith77: We don't have the Rails problem thanks to Twig as the order of execution is the right one by default (the layout is executed first); it means that we can have the flush feature without any change to how the core works. As @stof mentioned, we are using `display`, not `render`, so we are streaming your templates for byte one.
---------------------------------------------------------------------------
by fabpot at 2011/12/21 09:36:41 -0800
@Seldaek: yes, I meant ESI with the PHP reverse proxy.
---------------------------------------------------------------------------
by fabpot at 2011/12/21 09:37:34 -0800
@Seldaek: I have `flush()` support for Twig on my todo-list. As you mentioned, It should be trivial to implement.
---------------------------------------------------------------------------
by fzaninotto at 2011/12/21 09:48:18 -0800
How do streaming responses deal with assets that must be called in the head, but are declared in the body?
---------------------------------------------------------------------------
by fabpot at 2011/12/21 09:52:12 -0800
@fzaninotto: What do you mean?
With Twig, your layout is defined with blocks ("holes"). These blocks are overridden by child templates, but evaluated as they are encountered in the layout. So, everything works as expected.
As noted in the commit message, this does not work with PHP templates for the problems mentioned in the Rails post (as the order of execution is not the right one -- the child template is first evaluated and then the layout).
---------------------------------------------------------------------------
by fzaninotto at 2011/12/21 10:07:35 -0800
I was referring to using Assetic. Not sure if this compiles to Twig the same way as javascript and stylesheet blocks placed in the head - and therefore executed in the right way.

Be more tolerant and also accept <esi:include ...></esi:include>
I know this is not 100% standards compliant, but:
We need to do some XHTML processing on the output using PHP's DOM extension and the underlying libxml2.
libxml2 seems to be unable to keep the <esi:include /> tag as such and will expand it to ```<esi:include ...></esi:include>```.
Note this has nothing to do with having LIBXML_NOEMPTYTAG set (http://php.net/manual/de/domdocument.savexml.php). Rather it seems to be a problem for libxml that it cannot recognize <esi:include> as an "EMPTY" tag (in the DTD sense) because it is not defined in a standard xhtml1-strict DTD.

you need to add the new component in the ``replace`` section of the main composer.json, and you also need to add it as a dependency for FrameworkBundle as it defines a service using it.

mentioning the move only once in the changelog would probably be enough (and it is especially not needed in the FrameworkBundle section IMO) but otherwise it's fine
