this clarifies the expected types and exceptions by much. and it fixes some logic flaws.
- missing info/methods in interfaces
- respecting Twig_LoaderInterface only accepting strings, not objects
related to fabpot/Twig#1183 but does not depend on it

f6c12bd [Templating] fix logic regarding template references and many phpdocs
As Composer is now widely used in the PHP world, having to run composer
install before running the test suite is expected. This also has the
nice benefit of removing a bunch of code, making things easier to
maintain (there is only one place to declare a dev dependency), and
probably more.
* 2.3:
Update JsonResponse.php
[HttpKernel] fixed the inline renderer when passing objects as attributes (closes#7124)
CookieJar remove unneeded var, Client remove unneeded else
[DI] Fixed bug requesting non existing service from dumped frozen container
Update validators.sk.xlf
[WebProfiler] fix content-type parameter
Replace romaji period characters with Japanese style zenkaku period characters
fixed CS
fixed CS
[Console] Avoided an unnecessary check.
Added missing French validator translations
typo first->second
Passed the config when building the Configuration in ConfigurableExtension
removed unused code
Fixed variable name used in translation cache
Conflicts:
src/Symfony/Component/Console/Event/ConsoleCommandEvent.php
The code has been duplicated and not moved for BC reasons.
This code has been duplicated in the Twig bundle to be able to decouple
the web profiler and the exception templates.
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.

Todo: -
I added limit parameter in some places, where it may be usefull. I did not check the context of what values may have been exploded. So to not break anything, I added +1 to limit parameter.
If you find out that in some places limit (or limit+1) is not important or meaningless, write a comment please and I will fix it.

Adding +1 just to be sure to not break anything is clearly something we won't do. What is the benefit of doing that anyway?

The main idea of making this PR was to notify about some places that may run faster with just adding one parameter to explode function.
If in code is someting like: ```list($a, $b) = explode(':', $s);```
Function ```explode``` will create n-items (depends on ```$s```), but we need in code only the first two items. There is no reason to let ```explode``` create more items in memory that are NEVER used in our code. The limit parameter is there for these situations, so let's use it.
I know that it is microoptimization and may look unimportant, but we are writing a framework - so people expect that code will be as fast as possible without this kind of mistakes.
As I've noticed above, I know that +1 is not ideal solution, but the fastest without debugging the code. I expect that someone (with good knowledge of that code) will look at it and write in comments if variable may contain 1 comma (dot or someting on what is doing the explode) or maybe 2 in some situations or more.
Anyway, +1 will not break anything, because same items are created as it is now, but no unnecessary item is created.

I'm +1 for adding the number to avoid problems but I'm -1 on the optimization side of things as it won't optimize anything.

*.. The main idea of making this PR was to notify about some places that **may** run faster ..*
I am also unsure the optimization is really an optimization, care to benchmark (with meaningful inputs)? As for the limit+1 thing, why would you want to +1 it? The number of ``list`` arguments should always reflect the ``limit`` parameter, no?
---------------------------------------------------------------------------

@helmer please try this simple benchmark:
```
<?php
header('Content-Type: text/plain; charset=UTF-8');
define('COUNT', 10000);
$source_string = 'aaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbbbbbbb:cccccccccccccccccccccccc:dddddddddddddddddddddd:eeeeeeeeeeeeeeeeeeeeeeeee:fffffffffffffffffffffffffff';
$start = microtime(true);
for ($i = 0; $i < COUNT; $i++) {
list($a, $b) = explode(':', $source_string);
}
$end = microtime(true)-$start;
echo 'without limit: '.$end."\n";
$start = microtime(true);
for ($i = 0; $i < COUNT; $i++) {
list($a, $b) = explode(':', $source_string, 2);
}
$end = microtime(true)-$start;
echo 'with limit: '.$end."\n";
```
My results are:
```
without limit: 0.057228803634644
with limit: 0.028676986694336
```
That is 50% difference (with APC enabled). Of course the result depends on the length of source string and if it's too short, the difference may be none or very very small. That's why I said, that it **may** run faster and is just a micro optimization.
---------------------------------------------------------------------------
by pulzarraider at 2011/12/08 23:18:12 -0800
@helmer And why +1? It depends on a code:
```
$source_string = 'aaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbbbbbbb:cccccccccccccccccccccccc';
list($a, $b) = explode(':', $source_string, 2);
var_dump($a, $b);
```
and
```
$source_string = 'aaaaaaaaaaaaaaaaaaaa:bbbbbbbbbbbbbbbbbbbbb:cccccccccccccccccccccccc';
list($a, $b) = explode(':', $source_string, 3);
var_dump($a, $b);
```
gives different results. That's why the content of the variable must be known.

@pulzarraider Thanks for the benchmark, seems like a gain enough. Although, we are more likely having a scenario of:
``explode(':', 'a🅱️c')`` vs ``explode(':', 'a🅱️c', 3)`` with a ``COUNT`` of 10, where the difference is not even in microseconds anymore :)
The limit addition alters the behaviour though, ie suddenly you can define a controller [logical name](http://symfony.com/doc/current/book/routing.html#controller-string-syntax) as ´´AcmeBlogBundle:Blog:show:something``, and things go downhill from there on.
All that aside, I'm +1 for setting the limit to the exact number of ``list`` parameters, but certainly not number+1, this is just too wtfy (as you said, this was a safety thing, but I reckon for this PR to be merged it needs to be +0).

Overall `list()` is ugly as it's not very explicit. Even though it would mean extra lines, it's better to `explode()` then explicitly assign variables:
```
$parts = explode(':', $foo);
$name = $parts[0];
$tel = $parts[1];
```
`list()` is one of those bad relics from the PHP past...
---------------------------------------------------------------------------
by fabpot at 2011/12/11 10:07:47 -0800
@drak: why is `list` not explicit? It is in fact as explicit as the more verbose syntax you propose.
---------------------------------------------------------------------------
by pulzarraider at 2011/12/11 13:08:50 -0800
@drak: I agree with @fabpot. In speech of benchmarks ```list``` is faster then using a helper variable.
@fabpot, @helmer I've changed explode's limit to be correct (without +1) and removed some changes from this PR, where I can't find out what the content of variable may be. Unit tests pass, so I think it's ready for merge.
The locale management does not require sessions anymore.
In the Symfony2 spirit, the locale should be part of your URLs. If this is the case
(via the special _locale request attribute), Symfony will store it in the request
(getLocale()).
This feature is now also configurable/replaceable at will as everything is now managed
by the new LocaleListener event listener.
How to upgrade:
The default locale configuration has been moved from session to the main configuration:
Before:
framework:
session:
default_locale: en
After:
framework:
default_locale: en
Whenever you want to get the current locale, call getLocale() on the request (was on the
session before).
Here are the new simplified rules:
* Required cache warmers are *always* executed when the Kernel boots for the first time;
* Optional cache warmers are *only* executed from the CLI via cache:warmup
These new rules means that all the configuration settings for the cache
warmers have been removed. So, if you want the best performance, remember to
warmup the cache when going to production.
This also fixed quite a few bugs.
The consequence of this commit is that variables are accessible that have been passed to a surrounding form helper.
Example template:
{% block my_widget_label %}
<label>{{ label }}
{% endblock %}
{% block my_widget_row %}
{# It is not necessary to explicitely pass through the label variable #}
{{ form_label(form) }}
{{ form_widget(form) }}
{% endblock %}
Example usage:
{{ form_row(form.mywidget, { 'label': 'My Widget' }) }}
