switch to array_replace instead of array_merge

we don't need the logic to merge numeric keys, as we don't have them. I could also improve the genrated code by PhpMatcherDumper a little by saving a function call.

[2.2][Routing] hostname pattern for routes

Bug fix: no
Feature addition: yes
Fixes the following tickets: #1762, #3276
Backwards compatibility break: no
Symfony2 tests pass: yes

This adds a hostname_pattern property to routes. It works like the pattern property (hostname_pattern can have variables, requirements, etc). The hostname_pattern property can be set on both routes and route collections.

Yaml example:

``` yaml
# Setting the hostname_pattern for a whole collection of routes

AcmeBundle:
    resource: "@AcmeBundle/Controller/"
    type: annotation
    prefix: /
    hostname_pattern: {locale}.example.com
    requirements:
        locale: en|fr

# Setting the hostname_pattern for single route

some_route:
    pattern: /hello/{name}
    hostname_pattern: {locale}.example.com
    requirements:
        locale: en|fr
        name: \w+
    defaults:
        _controller: Foo:bar:baz
```

Annotations example:

``` php
<?php

/**
 * Inherits requirements and hostname pattern from the collection
 * @Route("/foo")
 */
public function fooAction();

/**
 * Set a specific hostnamePattern for this route only
 * @Route("/foo", hostnamePattern="{_locale}.example.com", requirements={"_locale="fr|en"})
 */
public function fooAction();

```

Performance:

Consecutive routes with the same hostname pattern are grouped, and a single test is made against the hostname for this group, so the overhead is very low:

```
@Route("/foo", hostnamePattern="a.example.com")
@Route("/bar", hostnamePattern="a.example.com")
@Route("/baz", hostnamePattern="b.example.com")
```

is compiled like this:

```
if (hostname matches a.example.com) {
    // test route "/foo"
    // test route "/bar"
}
if (hostname matches b.example.com) {
    // test route "/baz"
}
```

The PR also tries harder to optimize routes sharing the same prefix:

```
@Route("/cafe")
@Route("/cacao")
@Route("/coca")
```

is compiled like this:

```
if (url starts with /c) {
    if (url starts with /ca) {
        // test route "/cafe"
        // test route "/cacao"
    }
    // test route "/coca"
}
```

Interesting. Have you looked at #3057, #3002?

Killer feature of #3057 : multiple hostnames per route.

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

by arnaud-lb at 2012-02-16T14:21:28Z

@Koc yes, the main difference is that this PR allows variables in the hostname pattern, with requirements, etc just like the path pattern. The other PRs use a `_host` requirement, which works like the `_method` requirement (takes a list of allowed hostnames separated by `|`).

> Killer feature of #3057 : multiple hostnames per route.

If you have multiple tlds you can easily do it like this:

``` yaml
hostbased_route:
  pattern:  /
  hostname_pattern: symfony.{tld}
  requirements:
     tld: org|com
```

Or with completely different domain names:

``` yaml
hostbased_route:
  pattern:  /
  hostname_pattern: {domain}
  requirements:
     domain: example\.com|symfony\.com
```

Requirements allow DIC %parameters%, so you can also put you domains in your config.yml.

This PR looks great, it's something like this I've been waiting for.

I know @fabpot said he's working on something similar but I think if he agrees with this it could be a great addition to the core.

@fabpot , @stof any objections about this PR if gets fully done?

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

by stof at 2012-02-16T20:00:21Z

Well, we already have 2 other implementations for this stuff in the PRs. @fabpot please take time to look at them

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

by stof at 2012-02-16T20:03:17Z

This one is absolutely not tested and seems to break the existing tests according to the description. So it cannot be reviewed as is.

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

by dlsniper at 2012-02-16T22:00:24Z

@stof I understand it's a WIP but the other PRs where ignored as well and like you've said, there's a bunch of PRs already on this issue all doing a thing or another. So an early feedback on this, or any other, could lead it to the right path in order to finally solve this issue.

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

by arnaud-lb at 2012-02-17T23:57:28Z

Added tests; others are passing now

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

by arnaud-lb at 2012-02-22T21:10:20Z

I'm going to add support for the Apache dumper and the XML loader; does this PR have a chance to be merged ? cc @fabpot @stof

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

by stof at 2012-02-22T22:05:23Z

@arnaud-lb We need to wait @fabpot's mind about the way he prefers to implement it to know which one can be merged.

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

by IjinPL at 2012-02-27T02:01:57Z

Forked @arnaud-lb *hostname_pattern* to add XML parasing support.

by stof at 2012-04-03T23:59:12Z

@arnaud-lb Please rebase your branch. It conflicts with master because of the move of the tests

@fabpot @vicb ping

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

by dlsniper at 2012-04-13T19:52:23Z

Hi,

If @arnaud-lb won't be able to rebase this I could help with some work on this but there's still the problem of actually choosing the right PR(s) for this issue. @blogsh says in his last commit that this PR is a bit better in his opinion but @fabpot needs to decide in the end.

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

by arnaud-lb at 2012-04-14T17:26:55Z

@stof rebased

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

by nomack84 at 2012-04-20T13:01:00Z

@fabpot Any final word about this pull request? It would be nice to have this feature ready for 2.1.

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

by asm89 at 2012-04-24T21:27:50Z

Using the `{_locale}` placeholder in the host would set the locale for the request just like it does now?

Another thing I'm wondering is how/if it should be possible to set the hostname pattern for all your routes, or at least when importing routes? Otherwise you'll end up repeating the same host pattern over and over again. I think this is also important when importing routes from third party bundles.

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

by fabpot at 2012-04-25T01:17:51Z

I'm reviewing this PR and I'm going to make some modifications. I will send a PR to @arnaud-lb soon.

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

by fabpot at 2012-04-25T03:10:18Z

I've sent a PR to @arnaud-lb arnaud-lb/symfony#3 that fixes some minor bugs and add support in more classes.

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

by fabpot at 2012-04-25T03:12:52Z

@asm89:

Placeholders in the hostname are managed in the same way as the ones from the URL pattern.

You can set a hostname pattern for a collection (like the prefix for URL patterns).

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

by Tobion at 2012-04-25T09:31:19Z

I think we need to change the contents of $variables, $tokens, and $hostnameTokens in the CompiledRoute. They contain redundant information and the content structure of these variables ist not documentation in any way. If we remove duplicated content and put it in a (single) well defined variable, it would also reduce the information that need to be saved in the generated class by the UrlGeneratorDumper.

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

by arnaud-lb at 2012-04-26T08:54:21Z

@fabpot thanks :) I've merged it

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

by stof at 2012-04-26T12:08:40Z

A rebase is needed

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

by fabpot at 2012-04-26T13:28:08Z

no need to rebase, I will resolve the conflicts when merging. I've still have some minor changes to do before merging though. Anyone willing to have a look at implementing the Apache dumper part?

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

by Tobion at 2012-04-26T14:59:00Z

@fabpot you want to merge this for 2.1 although it introduces big changes that need extensive review and testing? But #3958 is not considered for 2.1? I thought we are in some sort of feature freeze for the components in order to not postpone the release.

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

by fabpot at 2012-04-26T17:21:09Z

@Tobion: I never said it will be in 2.1. The plan is to create a 2.1 branch soon so that we can continue working on 2.2.

and backport changes from 2.2

Details:
- does not take case into account when checking the host (the `Request` always returns a lowercase value) to protect against user typo,
- makes the constructor case proof by invoking setters rather than setting properties directly (you could then add un unreachable method i.e; `get`)

Please propagate to 2.1/2.2 if accpeted. Thanks.

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

by schmittjoh at 2012-11-12T09:12:56Z

Is there a reason for this BC break other than a cosmetical tweak?

If not strictly necessary, I'd like to see these kind of changes being scheduled for 3.0.

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

by fabpot at 2012-11-12T09:29:35Z

Of course, I don't want to make this change without a reason and indeed, I forgot to mention the why of this change. Let me explain.

I've been working on the integration of the Symfony web profiler into other OSS that use HttpKernel like Silex and Drupal for quite some time now. That's why I developed the new namespace feature in Twig, that's why I've refactored the web profiler to only use Twig and not the templating component. One of the last step is this PR, which reduces the number of dependencies to be able to use the WebProfiler bundle.

So, this change is not cosmetic, but one more step towards the goal of making the web profiler more reusable.

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

by schmittjoh at 2012-11-12T13:22:28Z

I see, makes sense. How about duplicating the code for now?

After looking through the history, it doesn't seem like it changes often
(the last real code change was a year ago). So, it should not be much more
maintenance effort, and we could keep BC here.

Of course, that's a possibility. But what for? I doubt that people are using this code. Are you using this code somewhere?

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

by schmittjoh at 2012-11-12T13:37:24Z

Yes, I believe that I'm using it both in JMSDebuggingBundle, and
JMSJobQueueBundle as both are rendering exception stack traces at some
point.

ok, fair enough. The code is now in the framework bundle as well.
[Routing] added more phpdoc and  replaced 'array of type' by 'Type[]'
[Routing] removed irrelevant string cast in Route

Even if the passed key is an integer, casting to string won't make any difference in array keys (it remains an int key).
