Improving performance on digit filtering
I haven't tested it on a productive system but I think it should be way faster to use filter_var() instead of preg_replace() for several reasons.
This is my first pull request for symfony and I don't know how you do those kind of performance tests but please verify my assumption if you can :-)
Maybe we can also use filter_var() to replace other regular expressions :-)
HTH =)

I have already. And it's way faster, otherwise I wouldn't have opened a pull request ;) But obviously it strongly depends on the length of the string and the environment. That's why I was wondering whether you have a general performance tests environment ;) Because the results strongly depend on other factors, there's - in my opinion - no point in exact results. If a general info is sufficient: my tests for the regex resulted in about 7 - 8 microseconds whereas the filter version only took 1.5 - 2 microseconds for the same string.

Set session.cookie_* parameters properly
Bug fix: yes
Feature addition: no
Backwards compatibility break: yes
Symfony2 tests pass: yes
Fixes the following tickets: /
Cookie parameters in $options are not prefixed with cookie_ the same is true for data returned from session_get_cookie_params.
I've marked this as BC because the options that get dumped into the container have different name. But I don't think anybody was actually changing them or accessing them in their bundles.
P.S. @drak also desires some credits for this PR as I incorporated some lines written by him in one of the iterations.

@mvrhov - what does this fix exactly? It looks like a different way of doing the same thing but now there is no default value on `cookie_httponly`.
---------------------------------------------------------------------------
by mvrhov at 2012-02-23T15:09:17Z
Like I said in description. $option contains some cookie options and none of them has cookie_ prefix.
And this prefix is needed in two cases:
- to properly merge defaults and override them with what user set
- in a foreach for for proper ini_set
Sorry non native speaker an a bit hard to explain, could you ping me in a couple of hours on IRC if this still doesn't make any sense.

Just for reference for those reading this ticket, `session_set_cookie_params()` alters the runtime ini settings it corresponds to see http://docs.php.net/manual/en/function.session-set-cookie-params.php so we agreed to remove the special handling that was present since it is redundant.

Fixes the following tickets: -
Todo: -
Rename ArraySessionStorage to make it clear the session is a mock for testing purposes only.
Has BC class for ArraySessionStorage
Added sanity check when starting the session.
Fixed typos and incorrect php extension test method
session_module_name() also sets session.save_handler, so must use extension_loaded() to check if module exist
or not.
Respect autostart settings.
Session object now implements SessionInterface to make it more portable.
AbstractSessionStorage and SessionSaveHandlerInterface now makes implementation
of session storage drivers simple and easy to write for both custom save handlers
and native php save handlers and respect the PHP session workflow.
This commit outsources the flash message processing to it's own interface.
Overall flash messages now can have multiple flash types and each type can
store multiple messages. For convenience there are now four flash types
by default, INFO, NOTICE, WARNING and ERROR.
There are two concrete implementations: one preserving the old behaviour of
flash messages expiring exactly after one page load, regardless of being
displayed or not; and the other where flash messages persist until explicitly
popped.
This commit outsources session attribute storage to it's own class.
There are two concrete implementations, one with structured namespace storage and the other
without.
Apache expects the response to already be in chunked format in that case,
which causes it to not deliver the streamed body.
If no Content-Length is set on the response, web servers will automatically
switch to chunked Transfer-Encoding, and handle the chunking for you.
Nginx does not share the issue that apache has, but will add the Content-
Length header too.

[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.

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.

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.
