the form is the root form and avoid to create unnecessary CSRF fields for nested fields.

@drak shouldn't all the options here: https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/Session/Storage/NativeSessionStorage.php#L266 be available for configuration, or am I just reading the source wrong and they already are?

[FrameworkBundle] Added server:run command (PHP 5.4 built-in web server)
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: [](http://travis-ci.org/michal-pipa/symfony)
Fixes the following tickets: -
Todo: -
PHP 5.4 comes with [built-in web server](http://www.php.net/manual/en/features.commandline.webserver.php). I've created command which allows to easily run Symfony2 application using this new feature.
Usage:
server:run [-d|--docroot="..."] [-r|--router="..."] [address]
Arguments:
address Address:port (default: 'localhost:8000')
Options:
--docroot (-d) Document root (default: 'web/')
--router (-r) Path to custom router script
Help:
The server:run runs Symfony2 application using PHP built-in web server:
app/console server:run
To change default bind address and port use the address argument:
app/console server:run 127.0.0.1:8080
To change default docroot directory use the --docroot option:
app/console server:run --docroot=htdocs/
If you have custom docroot directory layout, you can specify your own
router script using --router option:
app/console server:run --router=app/config/router.php
See also: http://www.php.net/manual/en/features.commandline.webserver.php
It requires PHP 5.4, otherwise this command will be disabled.
I think that this is very convenient (especially for new users). All you have to do is download Symfony, install vendors and run this command. You don't have to configure "real" web server, in fact any other server is not required. You don't have cache and logs permission problem, because server runs with your local user permissions.

Great feature! I was about to write something like this when I saw that you have already started implementing this :)
Some issues:
1. Missing newlines at the end of the files
2. If I try this server command with the default Symfony Standard Edition Acme demo the links on the main page do not work. The demo link links to "//demo" and the configurator link to "//_configurator". If I go to `localhost:8000/demo` directly the page is rendered as usual and all sub links are generated correctly. I could solve the problem by adding one line:
$_SERVER['SCRIPT_FILENAME'] = 'ANYTHING';
require 'app_dev.php';
I'm not sure where this problem comes from. Do you experience the same behaviour? Otherwise I'll do some more investigations to find the source of the problem.
3 . I think it would be a nice feature if you would generate a router.php based on the setting of the --env flag if no custom router file has been specified. This way it would be easy to switch between dev and prod.

I can reproduce this by changing front controller name from `app.php` to `app_dev.php`. I'll investigate on this.

You can easily change environment specifying front controller in URL. It works exactly the same way as default Apache configuration. This is intended behavior, as it would be misleading if every server had different rewrite rules.
If you really want to change it, then you can write your own router and pass it as a value to `router` option.

Wasn't aware that github omits the trailing white line, sorry.
Normally I use a rather inflexible nginx configuration, so I also wasn't aware of this (rather obvious) trick of changing the url. Thanks for that.

@blogsh it does not omit it. It displays it in the Linux way where the newline char is part of the line (and so there is a message ``no newline at end of file`` in the diff when it is missing).

@blogsh I've fixed router script. Now you can use both front controllers.

I've also hardcoded front controller name in router script and removed global variable, as there was no way to unset it.

by Tobion at 2012-02-11T21:33:32Z
Do I see it correctly that we cannot set a default template on a per hinclude tag basis? But only global?
That's not really usefull when javascript is disabled because it should resemble the content to be included as an alternative.
---------------------------------------------------------------------------
by stof at 2012-02-11T21:42:15Z
@Tobion currently it is not possible. But changing the content on a tag basis may require changing the way the render tag look like (as there is no content in the tag currently) so this needs further discussion and @fabpot said he wants to merge a first implementation without it. See the discussion above.

[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.
---------------------------------------------------------------------------
by lsmith77 at 2011/12/21 08:54:35 -0800
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.
---------------------------------------------------------------------------

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.

by stof at 2011/12/22 11:13:31 -0800
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
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');
