Now all error messages goes to stdout, we cannot separate error
from normal behaviour, this enables writing to stderr stream,
so scripts ran e.g. from cron, can benefit from this well known concept.
There are 2 much nicer implememntations, but:
1) First requires to break the `@api` tagged interfaces.
2) Second requires rewrite of `execute` command declatarion all commands in bundles.

8713c2d [DoctrineBridge][DoctrineBundle] Refactored the DBAL logging
Discussion
----------
[DoctrineBridge][DoctrineBundle] Refactored the DBAL logging
This allows enabling the logging and the profiling separately. This is useful for instance when doing batch processing leading to memory issue because of the profiling. In such case, the only solution currently is to disable the logging totally whereas disabling only the use of the profiler would allow seeing the queries in the logs (and the profiles are not collected in the CLI anyway).
I'm not sure about the place where the ``Stopwatch`` should be used. Keeping it in the ``DbalLogger`` with Monolog was the easy way as it allows using the DBAL class directly to collect queries for the profiler but technically the ``Stopwatch`` is used by the profiler.
the bundle changes are part of the PR to avoid letting the bundle in a broken state. I will also submit them to the doctrine/DoctrineBundle repo

[HttpKernel] Add Kernel::terminate() and HttpKernel::terminate() for post-response logic
This came out of a discussion on IRC about doing stuff post-response, and the fact that right now there is no best practice, and it basically requires adding code after the `->send()` call.
It's an attempt at fixing it in an official way. Of course terminate() would need to be called explicitly, and added to the front controllers, but then it offers a standard way for everyone to listen on that event and do things without slowing down the user response.
---------------------------------------------------------------------------
by stof at 2011/12/06 02:41:26 -0800
We discussed it on IRC and I suggested a way to avoid the BC break of the interface: adding a new interface (``TerminableInterface`` or whatever better name you find) containing this method.
HttpKernel, Kernel and HttpCache can then implement it without breaking the existing apps using the component (Kernel and HttpCache would need an instanceof check to see if the inner kernel implements the method)
For Symfony2 users it will mean they have to change their front controller to benefit from the new event of course, but this is easy to do.
Btw, Silex can then be able to use it without *any* change for the end users as it can be done inside ``Application::run()``

Any real-world use case for this?
---------------------------------------------------------------------------
by Seldaek at 2011/12/07 08:10:31 -0800
Doing slow stuff after the user got his response back without having to implement a message queue. I believe @pminnieur wanted to use it to send logs to loggly?
---------------------------------------------------------------------------
by pminnieur at 2011/12/07 09:08:41 -0800
Its a good practice to defer code execution without the introduction of a new software layer (like gearman, amqp, whatever tools people use to defer code execution) which may be way too much just for the goal of having fast responses, whatever my code does.
My real world use case which made me miss this feature the first time:
> I have a calendar with a scheduled Event. For a given period of time, several Event entities will be created, coupled to the scheduled event (the schedule Event just keeps track of `startDate`, `endDate` and the `dateInterval`). Let's say we want this scheduled Event to be on every Monday-Friday, on a weekly basis, for the next 10 years.
This means I have to create `10*52*5` Event entities before I could even think about sending a simple redirect response. If I could defer code execution, I'd only save the scheduled Event, send the redirect response and after that, I create the `10*52*5` entities.
The other use case was loggly, yes. Sending logging data over the wire before the response is send doesn't make sense in my eyes, so it could be deferred after the response is send (this especially sucks if loggly fails and i get a 500 --the frontend/public user is not interested in a working logging facility, he wants his responses).
---------------------------------------------------------------------------
by mvrhov at 2011/12/07 10:07:03 -0800
This would help significantly, but the real problem, that your process is busy and unavailable for the next request, is still there.
---------------------------------------------------------------------------
by fabpot at 2011/12/07 10:15:18 -0800
I think this is the wrong solution for a real problem.
Saying "Its a good practice to defer code execution without the introduction of a new software layer" is just wrong.
It is definitely a good practice to defer code execution, but you should use the right tool for the job.
I'm -1.
---------------------------------------------------------------------------
by pminnieur at 2011/12/07 10:25:44 -0800
It should just give a possibility to put unimportant but heavy lifting code behind the send request with ease. With little effort people could benefit from the usage of `fastcgi_finish_request` without introducing new software, using `register_shutdown_function` or using `__destruct `(which works for simple things, but may act weird with dependencies).
It should not simulate node.js ;-) I agree that the real problem is not solved, but small problems could be solved easily. I personally don't want to setup RabbitMQ or whatever, maintain my crontab or any other software that may allow me to defer code execution.
---------------------------------------------------------------------------
by Seldaek at 2011/12/08 01:08:32 -0800
@fabpot: one could say that on shared hostings it is still useful because they generally don't give you gearman or \*MQs. Anyway I think it'd be nice to really complete the HttpKernel event cycle.
---------------------------------------------------------------------------
by pminnieur at 2011/12/08 01:48:57 -0800
not only on shared hostings, sometimes teams/projects just don't have the resources or knowledge or time to setup such an infrastructure.
---------------------------------------------------------------------------
by videlalvaro at 2011/12/08 01:53:06 -0800
I can say we used `fastcgi_finish_request` quite a lot at poppen with symfony 1.x. It certainly helped us to send data to Graphite, save XHProf runs, send data to RabbitMQ, and so on.
For example we used to connect to RabbitMQ and send the messages _after_ calling `fastcgi_finish_request` so the user never had to wait for stuff like that.
Also keep in mind that if you are using Gearman or RabbitMQ or whatever tool you use to defer code execution… you are not deferring the network connection handling, sending data over the wire and what not. I know this is obvious but is often overlooked.
So it would be nice to have an standard way of doing this.
---------------------------------------------------------------------------
by henrikbjorn at 2011/12/13 01:42:23 -0800
This could have been useful recently while implementing a "Poor mans cronjob" system. The solution was to do a custom Response object and do the stuff after send have been called with a Connection: Close header and ignore_user_abort(); (Yes very ugly)

Fixes the following tickets: #2153
The purpose is to make it easier for other implementations that only implement parts of the interface due to different underlying approaches like the JMSSerializerBundle.
---------------------------------------------------------------------------
by schmittjoh at 2011/11/01 03:36:17 -0700
Actually, you can keep the current interface and I will just provide an adapter, sth like the following:
```php
<?php
class SymfonyAdapter implements SymfonyInterface
{
public function __construct(BundleInterface $serializer) { /* ... */ }
// symfony serializer methods mapped to bundle methods
}
```
I like to provide an adapter instead of implementing the interface directly since the bundle can be used standalone right now, and I don't want to add a dependency on the component just for the sake of the interface.
However, I do not completely see the purpose of the component. When would someone be recommended to use it? Everything the component does, the bundles does at the same level with the same complexity or simplicity (however you want to view that).
---------------------------------------------------------------------------
by lsmith77 at 2011/11/01 03:40:55 -0700
standalone in what way? you mean even out of the context of Symfony? In that context imho you should ship that code outside of a Bundle.
Regardless, how will that adaptor work? How would you implement methods like ``getEncoder()``? Afaik you can't and this is what this PR is about, splitting the interface to enable people to more finely specify what they provide.
---------------------------------------------------------------------------
by schmittjoh at 2011/11/01 04:03:56 -0700
I would just throw exceptions when something is not supported.
The more important question though is what is the goal of the component in the long-term, i.e. what problems is it supposed to solve, or in which cases should it be used?
Because right now it seems to me - correct me if I'm wrong - that the only purpose is that people don't have to install an extra library. However, that might even be frustrating for users because they need to migrate their code to the bundle as soon as they need to customize the serialization process which you need in 99% of the cases. For deserialization, the situation in the component is even worse. So, if my assessment is correct here (i.e. component to get started fast, if you need more migrate to the bundle), I think it would be better and less painful to have them start with the bundle right away.
---------------------------------------------------------------------------
by lsmith77 at 2011/11/01 04:15:10 -0700
Well then imho it would be better to split the interface.
I think the serializer component is sufficient for many situations and imho its easier to grok. Furthermore the normalizer/encoder concept it can be used in situations where JMSSerializerBundle cannot be used.
And splitting up the interfaces has exactly the goal of reducing the "frustrations" caused by out growing the the component.
---------------------------------------------------------------------------
by schmittjoh at 2011/11/01 04:29:39 -0700
I don't agree, but it's a subjective thing anyway.
So, whatever interface you come up with (preferably as few methods as possible), I will provide an adapter for it.

by stof at 2011/11/08 11:37:40 -0800
@lsmith77 what about doing the same for the ``NormalizerInterface`` instead of adding a new interface with a confusing name ? The Serializer class could implement ``Normalizer\NormalizerInterface`` by adding the 2 needed methods instead of duplicating part of the interface.
The next step is to refactor the Serializer class so that it choose the encoder and the decoder based on the ``support*`` methods. But this could probably be done in a separate PR.
---------------------------------------------------------------------------
by lsmith77 at 2011/11/08 11:51:27 -0800
yeah .. i wanted to do that once we are in agreement on the encoder stuff. question then is if we should again split off Denormalization. i guess yes.

If you merge it I am afraid I might get lazy and not write tests. This is why I changed the topic to WIP. I promise to finish this on the weekend.
Note however I was planning to write the tests for 2.0 and send them via a separate PR.
Once that PR is merged into 2.0 and master. I would then refactor them to work for this PR.
This way both 2.0 and master will have tests.

@fabpot ok i am done from my end.
@schmittjoh would be great if you could look over the final interfaces one time and give your blessing that you will indeed be able to provide implementations for these interfaces inside JMSSerializerBundle (even if just via an adapter)

@schmittjoh without them determining if something is supported will always require an exception, which is pretty expensive. especially if one iterates over a data structure this can cause a lot of overhead.

yes .. this serializer .. since it traverses the tree and decides what is the current normalizer one by one (aka not via visitors as in your implementation). without the supports*() methods it would need to have the normalizer throw exceptions, but this is not exceptional, its the normal code flow to have to iterate to find the correct normalizer.
---------------------------------------------------------------------------

hmm .. i guess we could .. these methods in a way are implementation specific and are mainly public because its different objects interacting with each other, though for users of the lib they can also be convenient at times.
---------------------------------------------------------------------------
by lsmith77 at 2011/12/14 09:13:53 -0800
ok i reviewed things again and just removed those two methods, since the possibility for these methods to be feasible is too tied to the implementation and for this particular implementation supportsEncoding() and supportsDecoding() are still available.
so all ready to be merged ..

[Config][HttpKernel][Templating] 'scheme://' paths not detected as absolute
Bug fix: yes
Feature addition: no
Backwards compatibility break: no (99%)
Symfony2 tests pass: yes
Fixes the following tickets: -
Todo: -
The method ```isAbsolutePath``` does not detect URL schemes as absolute. This makes imposible the use of wrappers to access remote files or the use of files (mostly configuration or templates) stored on phar archives (uses the scheme ```phar://``` in the path).
Three classes implement this methods: ```Symfony\Component\Config\FileLocator```, ```Symfony\Component\HttpKernel\Util\Filesystem``` and ```Symfony\Component\Templating\Loader\FilesytemLoader```. All are updated. Also includes a new check on all related tests (```Symfony\Component\HttpKernel\Util\Filesystem``` lacks of test).

[FrameworkBundle][CssSelector][HttpFoundation][HttpKernel] [Security][Validator] Minor optimizations for "explode" function
Bug fix: no

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

@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.
