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.

Fixed exception that was thrown when doing:
$builder->add('createdAt', 'date', array('data' => new \DateTime()));
On a side note, the options passed to `FieldType::getDefaultOptions` now always also contain the default options of any parent types. This is necessary if you want to be independent of how `getDefaultOptions` is implemented in the parent type and still rely on the already defined values.
As a result, `FieldType::getParent` doesn't see default options anymore. This shouldn't be a big problem, because this method only relies on options in few cases. If it does, options now need to be checked for existence with `isset` before being used (BC break).

[Validator] Added GroupSequenceProvider
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: ![](https://secure.travis-ci.org/blogsh/symfony.png?branch=dynamic_group_sequence)
As discussed in #3114 I implemented the "GroupSequenceProvider" pattern for the validator component. It allows the user to select certain validation groups based on the current state of an object. Here is an example:
/**
* @Assert\GroupSequenceProvider("UserGroupSequnceProvider")
*/
class User
{
/**
* @Assert\NotBlank(groups={"Premium"})
*/
public function getAddress();
public function hasPremiumSubscription();
}
class UserGroupSequenceProvider implements GroupSequenceProviderInterface
{
public function getValidationGroups($user)
{
if ($user->hasPremiumSubscription()) {
return array('User', 'Premium');
} else {
return array('User');
}
}
}
With this patch there are two mechanisms to define the group sequence now. Either you can use @GroupSequence to define a static order of validation groups or you can use @GroupSequenceProvider to create dynamic validation group arrays.
The ClassMetadata therefore has methods now which implement quite similar things. The question is whether it would make sense to interpret the static group sequence as a special case and create something like a DefaultGroupSequenceProvider or StaticGroupSequenceProvider which is assigned by default. This would cause a BC break inside the validator component.
---------------------------------------------------------------------------
by bschussek at 2012-01-28T13:39:54Z
I like the implementation, but I think we should differ a little bit from Java here.
1. `GroupSequenceProviderInterface` should be implemented by the domain classes themselves (`User`), not by a separate class.
2. As such, the parameter `$object` from `getValidationGroups($object)` can be removed
3. `ClassMetadata::setGroupSequenceProvider()` should accept a boolean to activate/deactivate this functionality. Also the check for the interface (does the underlying class implement it?) should be done here
Apart from that, special cases need to be treated:
* A definition of a group sequence and a group sequence provider in the same `ClassMetadata` should not be allowed. Either of them must not be set.
* Metadata loaders must take care of settings made by parent classes. If `Animal` is extended by `Dog`, `Animal` defines a group sequence (or group sequence provider) and `Dog` a group sequence provider (or group sequence), only the setting of `Dog` should apply
---------------------------------------------------------------------------
by blogsh at 2012-01-28T21:25:37Z
Changes of the latest commit:
- GroupSequenceProviderInterface has to be implemented by the domain class
- The annotation/configuration options let the user define whether the provider is activated or not (is this neccessary at all?)
- An error is thrown if the user wants to use static group sequences and the provider simultaneously
At the moment neither the static group sequence nor the provider is inherited from parent classes or interfaces. I don't know if it would make sense to enable this feature. There could be problems if a user wants to define a static group sequence in the parent class and a sequence provider in the child class.
---------------------------------------------------------------------------
by bschussek at 2012-01-30T13:07:04Z
> There could be problems if a user wants to define a static group sequence in the parent class and a sequence provider in the child class.
In this case, the setting in the child class should override the setting of the parent class.
But we can leave this open for now. As it seems, [this issue is unresolved in Hibernate as well](https://hibernate.onjira.com/browse/HV-467).

by Maks3w at 2012-02-05T09:52:21Z
One problem was that. Now I initialized the unit test with a execution
context mockup and works good.
Another problem I found is in the rules for upgrade from 2.0 to
2.1:
In v2.0: with setMessages() only one argument is mandatory ($message)
In v2.1: With the new way, addViolation(), then you need 2 arguments.
But, in v2.0 with the new way, addViolation, required 3 arguments.
So for preserve forward and backward compatibility, you need pass 3
arguments to addViolation() I think that it is helpfull and could be written in the
doc.
At the last one ¿What is the purpose of the third argument? ¿Can I pass
any object as invalid value?
Thanks
---------------------------------------------------------------------------
by bschussek at 2012-02-05T10:45:16Z
The last argument should always be the validated value that caused the constraint to fail.

![Travis Build Status](https://secure.travis-ci.org/bschussek/symfony.png?branch=issue1540)
Adds functionality for calling `addXxx` and `removeXxx` method in your model. All types returning a collection of values are affected: "collection", "choice" (with multiple selection) and "entity" (with multiple selection).
Example:
class Article
{
public function addTag($tag) { ... }
public function removeTag($tag) { ... }
public function getTags($tag) { ... }
}
And the controller:
$form = $this->createFormBuilder($article)
->add('tags')
->getForm();
Upon modifying the form, addTag() and removeTag() are now called appropiately.

@bschussek my point is that I can stand hard-coded priorities which are error prone. A better solution might be to introduce constants (in `FormEvents` / `FormEventPriorities` ?) with meaningful names.
---------------------------------------------------------------------------
by bschussek at 2012-02-02T10:21:52Z
@stof Rebased
@vicb I know, but who is responsible for managing priorities? There is no central entitty that can do this. (btw this is a general problem of the priority system of the EventDispatcher)
@fabpot Ready to merge.
---------------------------------------------------------------------------
by vicb at 2012-02-02T10:23:28Z
@bschussek doesn't each form has is own dispatcher so there is no need for a global registry here, something local to the form could be good enough.
The listener is used by the Collection type as well as the Choice and Entity type (with multiple
selection). The effect is that you can have for example this model:
class Article
{
public function addTag($tag) { ... }
public function removeTag($tag) { ... }
public function getTags($tag) { ... }
}
You can create a form for the article with a field "tags" of either type "collection" or "choice"
(or "entity"). The field will correctly use the three methods of the model for displaying and
editing tags.

[Form] read_only and disabled attributes (closes#1974)
1. Removed ``readOnly`` property from ``Form``, as it is no longer required
2. Introduced ``disabled`` property to ``Form``, behaves exactly like ``readOnly`` used to
3. Added ``disabled`` property to fields, defaults to ``false``, renders as ``disabled="disabled"``

---------------------------------------------------------------------------
by helmer at 2012-01-26T17:46:17Z
I changed ``Form`` and ``FormBuilder`` property ``readOnly`` to ``disabled``. On second thought, this is perhaps not such good change - while readOnly somewhat implied the use-case, disabled no longer does.
Perhaps something else, like ``bindable`` (as not to confuse with read_only attribute of Fields)?

I am working implementing client side validation in a bundle that adds validation rules via a form builder. I am currently unable to pull the validators from the Form class which is making the implementation incredibly difficult.

---------------------------------------------------------------------------

Yes, I can do that might be later today.
A new ExecutionContext is now created everytime that GraphWalker::walkConstraint() is
launched. Because of this, a validator B launched from within a validator A can't break
A anymore by changing the context.
Because we have a new ExecutionContext for every constraint validation, there is no point
in modifying its state anymore. Because of this it is now immutable.

Not sure if it's a bug in this PR or in #3156, but the labels get replaced by their keys:
```php
<?php
use Symfony\Component\Form\Extension\Core\ChoiceList\ChoiceList;
use Symfony\Component\Form\Extension\Core\ChoiceList\LazyChoiceList;
use Symfony\Component\Form\Extension\Core\ChoiceList\SimpleChoiceList;
class MyChoiceList extends LazyChoiceList {
protected function loadChoiceList() {
$choices = array(
'bla' => 'blaaaaaahhhh',
);
return new SimpleChoiceList($choices, array(), ChoiceList::COPY_CHOICE, ChoiceList::COPY_CHOICE);
}
public function getChoices() {
$choices = parent::getChoices();
// $choices is array('bla' => 'bla')
return $choices;
}
}

---------------------------------------------------------------------------
by stof at 2012-01-30T16:07:41Z
@craue the ``SimpleChoiceList`` is an implementation using the same string as label and value. If you need different ones, you need to use the ``ChoiceList`` implementation.

well, the SimpleChoiceList is for simple cases (thus its naming) where you want the same for the label and the values. And if you look at the class, you will see it extends the ChoiceList implementation which is the generic one.
---------------------------------------------------------------------------
by craue at 2012-01-30T16:53:36Z
For me, "simple" would mean that it just takes the array given, using keys as indices and values as labels. No fancy stuff messing around with anything. :D But, is there anything wrong in this code or in mine? @bschussek: Please enlighten me.
---------------------------------------------------------------------------
by bschussek at 2012-01-30T17:16:58Z
You are both wrong :) `getChoices` does not return the choices with their associated labels anymore. What you get now are the choice indices as array keys and the choice values as array values. How both are determined depends on the index and value generation strategy, which, in your case, are both COPY_CHOICE.
The difference between simple and complex choice lists is, that simple choice lists can only contain scalar values as choices, while other choice lists (such as ObjectChoiceList, EntityChoiceList) may contain objects as choices.
Choice labels are now stored in ChoiceView objects, which are returned by the various `get*Views` methods.
---------------------------------------------------------------------------
by craue at 2012-01-30T18:07:43Z
It's pretty annoying having provided an array with keys and values when initializing the `ChoiceList` but being unable to retrieve it again. Guess I just over-used or even abused those choice lists as kind of (not only form related) lookup tables.
---------------------------------------------------------------------------

@craue: What's your use case?
---------------------------------------------------------------------------
by craue at 2012-01-30T20:10:16Z
I just used choice lists extensively, even for not directly form-related stuff. In one case, I'm using two of them (which are also used individually) to build up a third one. That went well using the old `ArrayChoiceList`s and their `getChoices` method. Just thinking about creating another set of model classes which just contain my lists. So for only one select field in a form it'll take three classes then: (A) a list, (B) a choice list based on A, (C) a choice form type based on B. Oh well ... :D

[Form] Improved ChoiceList implementation and made form naming more restrictive
Bug fix: yes
Feature addition: yes
Backwards compatibility break: **yes**
Symfony2 tests pass: yes
Fixes the following tickets: #2869, #3021, #1919, #3153
Todo: adapt documentation
![Travis Build Status](https://secure.travis-ci.org/bschussek/symfony.png?branch=issue1919)
The changes in this PR are primarily motivated by the fact that invalid form/field names lead to various problems.
1. When a name contains any characters that are not permitted in HTML "id" attributes, these are invalid
2. When a name contains periods ("."), form validation is broken, because they confuse the property path resolution
3. Since choices in expanded choice fields are directly translated to field names, choices applying to either 1. or 2. lead to problems. But choices should be unrestricted.
4. Unless a choice field is not expanded and does not allow multiple selection, it is not possible to use empty strings as choices, which might be desirable in some occasions.
The solution to these problems is to
* Restrict form names to disallow unpermitted characters (solves 1. and 2.)
* Generate integer indices to be stored in the HTML "id" and "name" attributes and map them to the choices (solves 3.). Can be reverted to the old behaviour by setting the option "index_generation" to ChoiceList::COPY_CHOICE
* Generate integer values to be stored in the HTML "value" attribute and map them to the choices (solves 4.). Can be reverted to the old behaviour by setting the option "value_generation" to ChoiceList::COPY_CHOICE
Apart from these fixes, it is now possible to write more flexible choice lists. One of these is `ObjectChoiceList`, which allows to use objects as choices and is bundled in the core. `EntityChoiceList` has been made an extension of this class.
$form = $this->createFormBuilder()
->add('object', 'choice', array(
'choice_list' => new ObjectChoiceList(
array($obj1, $obj2, $obj3, $obj4),
// property path determining the choice label (optional)
'name',
// preferred choices (optional)
array($obj2, $obj3),
// property path for object grouping (optional)
'category',
// property path for value generation (optional)
'id',
// property path for index generation (optional)
'id'
)
))
->getForm()

Rather than passing `choices` and a `choice_labels` arrays to the view would it make sense to introduce a `ChoiceView` class and pass one array of objects?

ad (2): Property paths contain three special characters needed for correct parsing: left/right bracket and period.
The rules for form naming are:
* Names may start with a letter, a digit or an underscore. Leading digits or underscores will be stripped from the "id" attributes.
* Names must only contain letters, digits, underscores, hyphens and colons.
* Root forms may have an empty name.

[Twig] [FrameworkBundle] added CSRF token helper
I've added a templating helper and Twig function for generating a CSRF token without the overhead of creating a form.
```html+jinja
<form action="{{ path('user_delete', { 'id': user.id }) }}" method="post">
<input type="hidden" name="_method" value="delete">
<input type="hidden" name="_token" value="{{ csrf_token('delete_user_' ~ user.id) }}">
<button type="submit">delete</button>
</form>
```
```php
<?php
class UserController extends Controller
{
public function delete(User $user, Request $request)
{
$csrfProvider = $this->get('form.csrf_provider');
if (!$csrfProvider->isCsrfTokenValid('delete_user_'.$user->getId(), $request->request->get('_token')) {
throw new RuntimeException('CSRF attack detected.');
}
// etc...
}
}
```
The test that is failing on Travis appears to be unrelated, but I may be wrong?
```

by pablodip at 2012-01-10T14:18:45Z
As you don't need forms to use the csrf provider, how about putting its service without the form prefix? It could even make sense to put the CsrfProvider as a component since you can use it standalone and in more cases than only forms. It would be a small component though.
---------------------------------------------------------------------------
by Tobion at 2012-01-10T17:54:14Z
I think it would be more clear to generate the token in the controller. Doing so in the template will spread the CSRF intention across template and controller. So I don't think this extension is necessary.
---------------------------------------------------------------------------
by kriswallsmith at 2012-01-10T17:58:14Z
@pablodip I'm open to the idea of a Csrf component. This would be a good place for some nonce classes as well.
@Tobion I disagree. One use case is for a list of users, each with a delete form. Iterating over the users in the controller and generating a token for each, just to iterate over them again in the view is a waste and adds complexity.
---------------------------------------------------------------------------
by Tobion at 2012-01-10T18:05:14Z
I see. But I don't understand why the intention needs to be different for each user to delete. Usually the intention is the same for each form type. I thought this is enough.
---------------------------------------------------------------------------
by kriswallsmith at 2012-01-10T18:06:13Z
Yes, a static intention would suffice.
---------------------------------------------------------------------------
by Tobion at 2012-01-10T18:07:08Z
Then your use case is not valid anymore.
---------------------------------------------------------------------------
by Tobion at 2012-01-10T18:12:25Z
I would suggest to make a cookbook article out of it about how to create a simple form without the form component.
And include such things as validating the result using the validator component and checking the CSRF.
---------------------------------------------------------------------------
by kriswallsmith at 2012-01-10T21:32:50Z
This helper makes it easier to use CSRF protection without a form and we should make it as easy as possible. Spreading the intention across controller and template is not concerning to me. Either way, a cookbook entry is a great idea.
---------------------------------------------------------------------------
by Tobion at 2012-01-10T21:47:12Z
Well, it's just one line more without this helper. So I disagree it makes it really easier when you know how to use the CsrfProvider which is a pre-condition anyway since you must still validate its correctness by hand.
---------------------------------------------------------------------------
by kriswallsmith at 2012-01-13T13:24:15Z
Another use case is when rendering a page with a bunch of simple buttons with different intentions: delete user, delete comment, follow, unfollow... Creating all of these in the controller just leads to spaghetti.

[Validator] Dynamic constraints
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
By now the Validator component is based on a per-class configuration of
constraints, but in some cases it might be neccessary to add new constraints
dynamically at runtime.
This pull request adds a "ConstraintProviderInterface" to the Validator component. If an object is validated that implements this interface the method "getConstraints" is used to add dynamic constraints:
class User implements ConstraintProviderInterface
{
protected $isPremium;
protected $paymentInformation;
public function getConstraints(ClassMetadata $metadata)
{
if ($this->isPremium) {
$metadata->addPropertyConstraint('paymentInformation', new NotBlank());
}
}
}

---------------------------------------------------------------------------
by bschussek at 2012-01-16T12:32:44Z
I think this is a good addition. I think we still have a naming problem though. When constraints are loaded using a static method, the default name for the loader method is `loadValidatorMetadata`. Since the method for dynamic constraint loading is basically the same, I think the two names should be related.
Solution (1): Rename the method in your interface to `loadDynamicValidatorMetadata`. Ugly and long.
class MyClass implements ConstraintProviderInterface
{
public static loadValidatorMetadata(ClassMetadata $metadata) ...
public loadDynamicValidatorMetadata(ClassMetadata $metadata) ...
}
Solution (2): Rename the default method name in `StaticMethodLoader` to `registerConstraints` and adjust the docs. Breaks BC.
class MyClass implements ConstraintProviderInterface
{
public static registerConstraints(ClassMetadata $metadata) ...
public registerDynamicConstraints(ClassMetadata $metadata) ...
}
@fabpot: Are we allowed to break BC here? If not, we should probably stick to (1).

This is wrong. The body for DELETE method is supposed to be empty or if present ignored.

[Validator] Improve support for optional/required fields in Collection constraint
Bug fix: no

Backwards compatibility break: no
Symfony2 tests pass: yes

![Travis Build Status](https://secure.travis-ci.org/bschussek/symfony.png?branch=collection-validator)
Improves the `Collection` constraint to test on a more granular level if entries of the collection are optional or required. Before this could only be set using the "allowExtraFields" and "allowMissingFields" options, but these are very general and limited.
The former syntax - without Optional or Required - is still supported.
Usage:
$array = array(
'name' => 'Bernhard',
'birthdate' => '1970-01-01',
);
$validator->validate($array, null, new Collection(array(
'name' => new Required(),
'birthdate' => new Optional(),
));
// you can also pass additional constraints for the fields
$validator->validate($array, null, new Collection(array(
'name' => new Required(array(
new Type('string'),
new MinLength(3),
)),
'birthdate' => new Optional(new Date()),
));

by schmittjoh at 2011-12-19T19:33:24Z
This looks much better than the previous PR. Thanks!
One thing, we also discussed this on Doctrine, the name "comparable" is used in most programming languages to perform a real compare operation that is ">", "<", or "=". In this case though, we are specifically interested in equality of two objects (we cannot establish a natural order between these objects). Java has no such interface as all objects naturally have an equals() method, .NET uses "Equatable" which looks a bit odd. Not sure if there are better names.
---------------------------------------------------------------------------
by canni at 2011-12-19T19:34:52Z
I think this is best of "both worlds" we have nice full-featured implementation suitable for most, and if someone needs advanced compare logic just implements interface. @stof @schmittjoh, what do you think?
---------------------------------------------------------------------------
by stof at 2011-12-19T19:36:55Z
@canni I already commented on the code, and I agree with @schmittjoh that the naming can be confusing
---------------------------------------------------------------------------
by jmikola at 2011-12-20T17:33:22Z
I don't mean to bikeshed, but I strongly agree with @schmittjoh about implications of "compare". I'm not concerned with the interface name so much as I am with `compareUser()`. Given that this method returns a boolean, I think it's best to prefix it with `is` (e.g. `isSameUser`, `isUserEqualTo`) or `equals` (e.g. `equalsUser`).
In this PR, the Token class is implementing the interface, so I think having "User" in the method name is a good idea. Naturally, if the interface was intended for User classes, we could do without it.
---------------------------------------------------------------------------
by canni at 2011-12-20T19:00:00Z
@jmikola in this PR Token class does not implement any additional interface, and `compareUser` is `private` and used internally. I don't stand still after this names, I'll update PR as soon as some decision about naming will be done.
---------------------------------------------------------------------------
by jmikola at 2011-12-21T02:29:59Z

---------------------------------------------------------------------------
by stof at 2011-12-21T10:58:38Z
it would probably be bettter. The meaning of ``true`` and ``false`` would then be the opposite of the current ones but this is not an issue IMO as it is a different method

[Console] Allow redefinition of application options descriptions
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
This allows you to redefine an `InputOption` as long as it keeps the same semantic (same default, same name, same alias, same modes). There are two purposes:
- Modifying the description with a more accurate one
- Making sure the option appears in your commands' help
Concrete example: I often want to provide a verbose version of commands. It's an elegant and very common pattern, but I basically can't document what is going to happen if you do `--verbose` since the base Application already defines `--verbose`. Also the `--verbose` option does not appear when you do `console <command> --help`, which means people probably won't think of using that option.

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-

[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.

wonder what the use case is for streaming a response, very interesting.

@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?
---------------------------------------------------------------------------

@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.

@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.
---------------------------------------------------------------------------

@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.

I'm really happy you've got this into the core, it's a great feature to have! Good work.
* 2.0:
[Tests] Skip segfaulting form test
Rename test file
[BrowserKit] added missing @return PHPDoc for the Client::submit() method.
also test PHP 5.3.2, since this is the official lowest supported PHP version

[DependencyInjection] Parameters with spaces are not resolved
Bug fix: yes

`ParameterBag` currently resolves anything between two `%` signs, which creates issues for any parameters in the DIC that are legitimate text. This PR enforces the [documented parameter convention](http://symfony.com/doc/2.0/book/service_container.html#service-parameters) so that only `%parameters.with.no_spaces%` are resolved.
I was considering using instead `^%([^\w\._-]+)%$`, but felt that was too constricting & could easily introduce issues with existing applications.

Is it really needed? I have a feeling that it enforces unneeded constraints, but I can be wrong of course.
---------------------------------------------------------------------------
by hlecorche at 2011/12/20 02:31:03 -0800
It's needed because with TextType field, and without the ValueToStringTransformer, the user data (when sending the form) can be an array !!!
For example:
- if there is a TextType field
- and if there is a MaxLengthValidator
- and if the user data (when sending the form) is an array
So the exception "Expected argument of type string, array given in src\Symfony\Component\Validator\Constraints\MaxLengthValidator.php at line 40" is thrown

@fabpot: we figured that priorities wouldn't be needed for cleaning .. haven't tested the PR, but conceptually it looks good to me and aside from the priority stuff its modeled after the cache warners.

@stof and @fabpot Another thought I just had. Should the `$this->getContainer()->get('cache_clearer')->clear($realCacheDir);` call in the `CacheClearCommand` be done before the warming?
---------------------------------------------------------------------------

indeed. the clearing should be done before the warming.
