I removed all usages of the deprecated _scheme requirement inside the Routing Component.
Most parts were pretty easy and after multiple refactorings I came up with the solution to have a Route::hasScheme() method and check against this method.
I also checked for performance and after trying in_array, arra_flip+isset and foreach, the last one was clearly the winner.
https://gist.github.com/Danez/7609898#file-test_performance-php
I also adjusted all tests that test '_scheme' to also check the new schemes-requirement.

The ExpressionLanguage component provides an engine that can compile and
evaluate expressions.
An expression is a one-liner that returns a value (mostly, but not limited to, Booleans).
It is a strip-down version of Twig (only the expression part of it is
implemented.) Like Twig, the expression is lexed, parsed, and
compiled/evaluated. So, it is immune to external injections by design.
If we compare it to Twig, here are the main big differences:
* only support for Twig expressions
* no ambiguity for calls (foo.bar is only valid for properties, foo['bar'] is only valid for array calls, and foo.bar() is required for method calls)
* no support for naming conventions in method calls (if the method is named getFoo(), you must use getFoo() and not foo())
* no notion of a line for errors, but a cursor (we are mostly talking about one-liners here)
* removed everything specific to the templating engine (like output escaping or filters)
* no support for named arguments in method calls
* only one extension point with functions (no possibility to define new operators, ...)
* and probably even more I don't remember right now
* there is no need for a runtime environment, the compiled PHP string is self-sufficient
An open question is whether we keep the difference betweens arrays and hashes.
The other big difference with Twig is that it can work in two modes (possible
because of the restrictions described above):
* compilation: the expression is compiled to PHP and is self-sufficient
* evaluation: the expression is evaluated without being compiled to PHP (the node tree produced by the parser can be serialized and evaluated afterwards -- so it can be saved on disk or in a database to speed up things when needed)
Let's see a simple example:
```php
$language = new ExpressionLanguage();
echo $language->evaluate('1 + 1');
// will echo 2
echo $language->compile('1 + 2');
// will echo "(1 + 2)"
```
The language supports:
* all basic math operators (with precedence rules):
* unary: not, !, -, +
* binary: or, ||, and, &&, b-or, b-xor, b-and, ==, ===, !=, !==, <, >, >=, <=, not in, in, .., +, -, ~, *, /, %, **
* all literals supported by Twig: strings, numbers, arrays (`[1, 2]`), hashes
(`{a: "b"}`), Booleans, and null.
* simple variables (`foo`), array accesses (`foo[1]`), property accesses
(`foo.bar`), and method calls (`foo.bar(1, 2)`).
* the ternary operator: `true ? true : false` (and all the shortcuts
implemented in Twig).
* function calls (`constant('FOO')` -- `constant` is the only built-in
functions).
* and of course, any combination of the above.
The compilation is better for performances as the end result is just a plain PHP string without any runtime. For the evaluation, we need to tokenize, parse, and evaluate the nodes on the fly. This can be optimized by using a `ParsedExpression` or a `SerializedParsedExpression` instead:
```php
$nodes = $language->parse($expr, $names);
$expression = new SerializedParsedExpression($expr, serialize($nodes));
// You can now store the expression in a DB for later reuse
// a SerializedParsedExpression can be evaluated like any other expressions,
// but under the hood, the lexer and the parser won't be used at all, so it''s much faster.
$language->evaluate($expression);
```
That's all folks!
I can see many use cases for this new component, and we have two use cases in
Symfony that we can implement right away.
## Using Expressions in the Service Container
The first one is expression support in the service container (it would replace
#8850) -- anywhere you can pass an argument in the service container, you can
use an expression:
```php
$c->register('foo', 'Foo')->addArgument(new Expression('bar.getvalue()'));
```
You have access to the service container via `this`:
container.get("bar").getvalue(container.getParameter("value"))
The implementation comes with two functions that simplifies expressions
(`service()` to get a service, and `parameter` to get a parameter value). The
previous example can be simplified to:
service("bar").getvalue(parameter("value"))
Here is how to use it in XML:
```xml
<parameters>
<parameter key="value">foobar</parameter>
</parameters>
<services>
<service id="foo" class="Foo">
<argument type="expression">service('bar').getvalue(parameter('value'))</argument>
</service>
<service id="bar" class="Bar" />
</services>
```
and in YAML (I chose the syntax randomly ;)):
```yaml
parameters:
value: foobar
services:
bar:
class: Bar
foo:
class: Foo
arguments: [@=service("bar").getvalue(parameter("value"))]
```
When using the container builder, Symfony uses the evaluator, but with the PHP
dumper, the compiler is used, and there is no overhead as the expression
engine is not needed at runtime. The expression above would be compiled to:
```php
$this->get("bar")->getvalue($this->getParameter("value"))
```
## Using Expression for Security Access Control Rules
The second use case in Symfony is for access rules.
As we all know, the way to configure the security access control rules is confusing, which might lead to insecure applications (see http://symfony.com/blog/security-access-control-documentation-issue for more information).
Here is how the new `allow_if` works:
```yaml
access_control:
- { path: ^/_internal/secure, allow_if: "'127.0.0.1' == request.getClientIp() or has_role('ROLE_ADMIN')" }
```
This one restricts the URLs starting with `/_internal/secure` to people browsing from the localhost. Here, `request` is the current Request instance. In the expression, there is access to the following variables:
* `request`
* `token`
* `user`
And to the following functions:
* `is_anonymous`
* `is_authenticated`
* `is_fully_authenticated`
* `is_rememberme`
* `has_role`
You can also use expressions in Twig, which works well with the `is_granted` function:
```jinja
{% if is_granted(expression('has_role("FOO")')) %}
...
{% endif %}
```
## Using Expressions in the Routing
Out of the box, Symfony can only match an incoming request based on some pre-determined variables (like the path info, the method, the scheme, ...). But some people want to be able to match on more complex logic, based on other information of the Request object. That's why we introduced `RequestMatcherInterface` recently (but we no default implementation in Symfony itself).
The first change I've made (not related to expression support) is implement this interface for the default `UrlMatcher`. It was simple enough.
Then, I've added a new `condition` configuration for Route objects, which allow you to add any valid expression. An expression has access to the `request` and to the routing `context`.
Here is how one would configure it in a YAML file:
```yaml
hello:
path: /hello/{name}
condition: "context.getMethod() in ['GET', 'HEAD'] and request.headers.get('User-Agent') =~ '/firefox/i'"
```
Why do I keep the context as all the data are also available in the request? Because you can also use the condition without using the RequestMatcherInterface, in which case, you don't have access to the request. So, the previous example is equivalent to:
```yaml
hello:
path: /hello/{name}
condition: "request.getMethod() in ['GET', 'HEAD'] and request.headers.get('User-Agent') =~ '/firefox/i'"
```
When using the PHP dumper, there is no overhead as the condition is compiled. Here is how it looks like:
```php
// hello
if (0 === strpos($pathinfo, '/hello') && preg_match('#^/hello/(?P<name>[^/]++)$#s', $pathinfo, $matches) && (in_array($context->getMethod(), array(0 => "GET", 1 => "HEAD")) && preg_match("/firefox/i", $request->headers->get("User-Agent")))) {
return $this->mergeDefaults(array_replace($matches, array('_route' => 'hello')), array ());
}
```
Be warned that conditions are not taken into account when generating a URL.
## Using Expressions in the Validator
There is a new Expression constraint that you can put on a class. The expression is then evaluated for validation:
```php
use Symfony\Component\Validator\Constraints as Assert;
/**
* @Assert\Condition(condition="this.getFoo() == 'fo'", message="Not good!")
*/
class Obj
{
public function getFoo()
{
return 'foo';
}
}
```
In the expression, you get access to the current object via the `this` variable.
## Dynamic annotations
The expression language component is also very useful in annotations. the SensoLabs FrameworkExtraBundle leverages this possibility to implement HTTP validation caching in the `@Cache` annotation and to add a new `@Security` annotation (see sensiolabs/SensioFrameworkExtraBundle#238.)

In #5989, it has unanimously been decided to renamed `hostname_pattern` to `hostname` and `pattern` to `path`. That makes a lot of sense and I would like to do the renaming now as `hostname_pattern` is new in Symfony 2.2, so I'd like to avoid breaking BC just after the release. As we are modifying the route options, I've also included changes introduced by @Tobion in #6049 which were discussed in #5990.
As everything is BC, I think it's wise to include that in 2.2. What do you think?

[Routing] removed tree structure from RouteCollection
BC break: yes (see below)
Deprecations: RouteCollection::getParent(); RouteCollection::getRoot()
tests pass: yes
The reason for this is so quite simple. The RouteCollection has been designed as a tree structure, but it cannot at all be used as one. There is no getter for a sub-collection at all. So you cannot access a sub-collection after you added it to the tree with `addCollection(new RouteCollection())`. In contrast to the form component, e.g. `$form->get('child')->get('grandchild')`.
So you can see the RouteCollection cannot be used as a tree and it should not, as the same can be achieved with a flat array!
Using a flat array removes all the need for recursive traversal and makes the code much faster, much lighter, less memory (big problem in CMS with many routes) and less error-prone.
BC break: there is only a BC break if somebody used the PHP API for defining RouteCollection and also added a Route to a collection after it has been added to another collection.
So
```
$rootCollection = new RouteCollection();
$subCollection = new RouteCollection();
$rootCollection->addCollection($subCollection);
$subCollection->add('foo', new Route('/foo'));
```
must be updated to the following (otherwise the 'foo' Route is not imported to the rootCollection)
```
$rootCollection = new RouteCollection();
$subCollection = new RouteCollection();
$subCollection->add('foo', new Route('/foo'));
$rootCollection->addCollection($subCollection);
```
Also one must call addCollection from the bottom to the top. So the correct sequence is the following (and not the reverse)
```
$childCollection->->addCollection($grandchildCollection);
$rootCollection->addCollection($childCollection);
```
Remeber, this is only needed when using PHP for defining routes and calling methods in a special order. There is no change required when using XML or YAML for definitions. Also, I'm pretty sure that neither the CMF, nor Drupal routing, nor Silex is relying on the tree stuff. So they should also still work.
cc @fabpot @crell @dbu
One more thing: RouteCollection wasn't an appropriate name for a tree anyway as a collection of routes (that it now is) is definitely not a tree.
Yet another point: The XML declaration of routes uses the `<import>` element, which is excatly what the new implementation of addCollection without the need of a tree does. So this is now also more analogous.

There's an issue somewhere in Drupal where we're trying to use addCollection() as a shorthand for iterating over one collection and calling add() on the other for each item. We can't do that, however, because the subcollections are not flattened properly when reading back and our current dumper can't cope with that. So this change would not harm Drupal at all, and would mean I don't have fix a bug in our dumper. :-) I cannot speak for any other projects, of course.

Discussion
----------
[Routing] fixed possible parameters conflict in apache url matcher
Bug fix: yes
Feature addition: no
Backwards compatibility break: no (as long as rewrite rules are generated after upgrading)
Symfony2 tests pass: yes
- This fixes a conflict in route parameters:
The rewrite rules currently pass route informations through environment variables:
`_ROUTING_DEFAULT_x`: passes the default value of parameter x
`_ROUTING__allow_x`: passes the information that method x was allowed for this route
`_ROUTING_x`: passes the value of parameter x
The problem is that naming a route parameter `DEFAULT_*` or `_allow_*` would not behave as expected.
I fixed this by namespacing all environment variables; e.g. parameters are in `_ROUTING_param_*`, defaults in `_ROUTING_default_*`, etc.
- The PR fixes a second issue: sometimes the variables are prefixed with multiple REDIRECT_. This PR handles this case by ignoring them all.
- This also improves performance a little:
Matching a route with two parameters and two default parameters 100K times: (`$_SERVER` was copied from a real request, so with many non `_ROUTING_` variables)

---------------------------------------------------------------------------
by arnaud-lb at 2012-10-27T14:50:08Z
There is an issue with default parameter values, I can't find how to fix that in a simple way. Before this PR, default values are never used (if a parameter is an optional not present in the url, the parameter's value is the empty string); after this PR, when a parameter is present and empty (e.g. a requirement like `.*`), its value is set to its default value.
---------------------------------------------------------------------------
by Tobion at 2012-10-29T01:36:08Z
The problem is, it's not consistent with the default php matcher. So one cannot safely exchange it with the apache matcher because it behaves differently under some (special) circumstances.
---------------------------------------------------------------------------
by fabpot at 2012-11-05T08:05:54Z
We need to move forward as I want to merge the hostname support in the routing ASAP to have plenty of time for feedback before the 2.2 release.

by arnaud-lb at 2012-11-05T09:22:02Z
@fabpot it sounds reasonable to me. Also, I've the hostname support branch is currently rebased so that it can be merged without this one.

You need to remove the type-hint from the constructor, and probably add an exception instead where the matching methods are called to ensure that either ``UrlMatcherInterface``, or ``RequestMatcherInterface`` were passed. Alternatively, you could also add such a check to the constructor.

Well, the RouterInterface extends UrlMatcherInterface anyway (and it should stay this way as it would be a huge BC break) so I guess most people will implement both interfaces when implementing the RquestMatcherInterface

@fabpot: Sorry, not sure how: Under 2.1.0 or in a new section? As the first or last entry of the list?

Ah ... so there were two pitfalls:
- PHPUnit clones the arguments of mocked functions. So they wouldn't equal.
- createGetResponseEventForUri() disables routing on purpose. So not using that helper, now.
Tests should be passing.

This pull request [passes](http://travis-ci.org/symfony/symfony/builds/1509054) (merged 7fab0118 into 1541fe26).
- The route compiler does not add extra space or line-feed,
- The generated regex does not use the 'x' modified any more,
- The PHP and apache matchers do not need to strip any chars (vs space and line feed before),
- The space characters are escaped according to the apache format

sure, done
Only + and % are now encoded in generated routes, since they are the only characters that, if not encoded, could cause problems/conflicts when decoded. Namely + turns into a space, and % followed by numbers could do funky things.
The matcher decodes everything which works since nothing will have %NN without being escaped, and + are escaped as well.

91f4097 [Routing] Better nesting for RouteCollections in dumped URL matcher classes With this change, a route prefixed with '/blogger' will be nested inside '/blog' (for example)
Discussion
----------
[Routing] Better nesting for RouteCollections in dumped URL matcher classes
Consider the following routing file:
_blog:
resource: "@AcmeDemoBundle/Resources/config/routing/BlogController.yml"
prefix: /blog
_blogger:
resource: "@AcmeDemoBundle/Resources/config/routing/BloggerController.yml"
prefix: /blogger
_bloggeroo:
resource: "@AcmeDemoBundle/Resources/config/routing/BloggerooController.yml"
prefix: /bloggeroo
_blogtest:
pattern: /blogtest
defaults: { _controller: AcmeDemoBundle:Blog:test }
login:
pattern: /login
defaults: { _controller: AcmeDemoBundle:Security:login }
Note: Each imported file contains two simple blog/blogger/bloggeroo routes (e.g. blog_index & blog_view)
With this change, the cached URL matcher looks something like this:
```php
<?php
class appprodUrlMatcher
{
public function match($pathinfo)
{
$allow = array();
if (0 === strpos($pathinfo, '/blog')) {
// blog_index
if (preg_match('#^/blog/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {...}
// blog_view
if (preg_match('#^/blog/(?P<year>\d{4})/(?P<month>\d{2})/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {...}
if (0 === strpos($pathinfo, '/blogger')) {
// blogger_index
if (preg_match('#^/blogger/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {...}
// blogger_view
if (preg_match('#^/blogger/(?P<year>\d{4})/(?P<month>\d{2})/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {...}
if (0 === strpos($pathinfo, '/bloggeroo')) {
// bloggeroo_index
if (preg_match('#^/bloggeroo/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {...}
// bloggeroo_view
if (preg_match('#^/bloggeroo/(?P<year>\d{4})/(?P<month>\d{2})/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {...}
throw 0 < count($allow) ? new MethodNotAllowedException(array_unique($allow)) : new ResourceNotFoundException();
}
throw 0 < count($allow) ? new MethodNotAllowedException(array_unique($allow)) : new ResourceNotFoundException();
}
// _blogtest
if ($pathinfo === '/blogtest') {...}
throw 0 < count($allow) ? new MethodNotAllowedException(array_unique($allow)) : new ResourceNotFoundException();
}
// login
if ($pathinfo === '/login') {...}
throw 0 < count($allow) ? new MethodNotAllowedException(array_unique($allow)) : new ResourceNotFoundException();
}
}
```
As far as I can see, you can throw the 404 earlier (as I've done), as by nesting all these possibilities, there is no chance another route will be matched outside the parent if statement.

You should follow Symfony [CS rules] (http://symfony.com/doc/current/contributing/code/standards.html), also you should modify tests.

Besides the inline `continue` statement, I can't see spot any other CS violations. I'm on to the updated tests.
---------------------------------------------------------------------------
by fabpot at 2011/06/13 02:19:14 -0700
What if you have this:
_blog:
resource: "@AcmeDemoBundle/Resources/config/routing/BlogController.yml"
prefix: /blog
login:
pattern: /login
defaults: { _controller: AcmeDemoBundle:Security:login }
_blogger:
resource: "@AcmeDemoBundle/Resources/config/routing/BloggerController.yml"
prefix: /blogger
You cannot send 404 early because the same `blog` prefix is used in two different places. I can see many things that will break with this patch. I'm pretty sure we can enhance the performance of the existing code but let's do that after 2.0.

@fabpot: The code was designed so it would work in these kind of circumstances. I ran the dumper against the routing file you provided and this is the output below.
I see no reason why you can't throw the 404 earlier, as by nesting everything with similar prefixes, we're eliminating the possibility that a route will ever be matched outside of that if statement.
```php
public function match($pathinfo)
{
$allow = array();
if (0 === strpos($pathinfo, '/blog')) {
// blog_index
if (preg_match('#^/blog/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {
...
}
// blog_view
if (preg_match('#^/blog/(?P<year>\d{4})/(?P<month>\d{2})/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {
...
}
if (0 === strpos($pathinfo, '/blogger')) {
// blog_index
if (preg_match('#^/blogger/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {
...
}
// blog_view
if (preg_match('#^/blogger/(?P<year>\d{4})/(?P<month>\d{2})/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {
...
}
throw 0 < count($allow) ? new MethodNotAllowedException(array_unique($allow)) : new ResourceNotFoundException();
}
throw 0 < count($allow) ? new MethodNotAllowedException(array_unique($allow)) : new ResourceNotFoundException();
}
// login
if ($pathinfo === '/login') {
...
}
throw 0 < count($allow) ? new MethodNotAllowedException(array_unique($allow)) : new ResourceNotFoundException();
}
```

Can you add some more tests to ensure that everything works fine and that we won't have regressions later on? Thanks.
* lmcd/master:
$code referenced but not defined in compileRoute()
[Routing] Optimised the PHP URL matcher dumper The cached URL matcher classes contain some unneeded logic. Consider the following example:
The cached URL matcher classes contain some unneeded logic. Consider the following example:
if (0 === strpos($pathinfo, '/Blog')) {
// blog_index
if (0 === strpos($pathinfo, '/Blog') && preg_match('#^/Blog/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {
return array_merge($this->mergeDefaults($matches, array ( '_action' => 'index',)), array('_route' => 'blog_index'));
}
}
The 2nd strpos is not required, as we have already satisfied this condition in the parent if statement.
My change will produce the following code for the same routing setup::
if (0 === strpos($pathinfo, '/Blog')) {
// blog_index
if (preg_match('#^/Blog/(?P<slug>[^/]+?)$#x', $pathinfo, $matches)) {
return array_merge($this->mergeDefaults($matches, array ( '_action' => 'index',)), array('_route' => 'blog_index'));
}
}
The _scheme requirement can be used to force routes to always match one given scheme
and to always be generated with the given scheme.
So, if _scheme is set to https, URL generation will force an absolute URL if the
current scheme is http. And if you request the URL with http, you will be redirected
to the https URL.
* fixes a problem with security (/foo/bar and /foo///bar are not the same URL as far as security is concerned)
* this can still be done in your web server configuration or by adding a core.request listener
