[HttpFoundation] Get correct client IP when using trusted proxy (Varnish)
Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: -
Todo: -
Note: This is reopened PR #2686 for 2.0 branch.
If using trusted proxy (Varnish, ...) the client IP must be identified from X-Forwarded-For header. The header has de-facto standard format:
X-Forwarded-For : client1, proxy1, proxy2,
where the value is a comma+space separated list of IP addresses, the left-most being the farthest downstream client, and each successive proxy that passed the request adding the IP address where it received the request from. See: http://en.wikipedia.org/wiki/X-Forwarded-For
Function getClientIp should return only one client IP, not a list of all nonimportant IPs as it's now. Similar example can be seen in Cake framework: http://api.cakephp.org/view_source/request-handler-component/#line-477
There are many ways how to chose the first IP from X-Forwarded-For header. Any other faster and more reliable way is welcome.

269a5e6 Added the ablity to get a requests ContentType
Discussion
----------
Added getContentType
I've added the ability for Symfony\Component\HttpFoundation\Request to return the ContentType from serverBag this uses the $formats array to determine if the requested ContentType is valid.

Have you considered squashing a couple of your commits? They seem doubled up.
Trivial, I know, but it will make each commit stand on its own (instead of appearing as a typo correction)

You may need to do a `git push -f origin master`. Check the commits tab to see the duplicate history:

Wheeeee, rebasing is fun!

Can you added some unit tests?
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).

[2.1] [HttpFoundation] Added support for the PATCH method
http://tools.ietf.org/html/rfc2068#section-19.6.1.1http://tools.ietf.org/html/rfc5789
---------------------------------------------------------------------------

According to the spec it seems that PATCH requests shouldn't be of application/x-www-form-urlencoded content-type so it shouldn't match the first if, and in the second it's probably wrong to default to application/x-www-form-urlencoded, no?
---------------------------------------------------------------------------
by lsmith77 at 2011/08/07 03:31:48 -0700
Hmm you are right. I assumed the diff would be encoded as ``application/x-www-form-urlencoded`` but there indeed is no indication of that in the spec. But given that the second case would still need some sort of handling for PATCH, just not sure what exactly ``$defaults['CONTENT_TYPE']`` should be set to.
---------------------------------------------------------------------------
by Seldaek at 2011/08/07 03:48:53 -0700
As I understand it, a PATCH request must specify a content-type or it's invalid, so we could just skip the second behavior if no content-type is present.
As your first link says:
The list of differences is in a format defined by the media type of the entity (e.g.,
"application/diff") and MUST include sufficient information to allow
the server to recreate the changes necessary to convert the original
version of the resource to the desired version.
Sounds like PATCH is highly application specific, and not so standardized, probably because it's not very useful for most purposes.
---------------------------------------------------------------------------
by lsmith77 at 2011/08/07 04:02:43 -0700
Yes, but to me this means that the patch is actually correct aside from the fact that its setting a default Content-Type, which I just corrected (not sure if this use of switch is ok with our coding style). Now if the Content-Type does end up being ``application/x-www-form-urlencoded`` then I would say its correct to decode it.

e80ce57 [HttpFoundation] Add REQUEST_TIME by default

[HttpFoundation] Add REQUEST_TIME by default
Without this the getting the REQUEST_TIME from the Request in tests is breaking.
This type of override is supported by MS MVC3 and is recommended by Google.
Also added ability to override request method via ?_method= when
request is made via GET.
* igorw/ipv6:
[HttpFoundation] minor optimization
minor adjustments suggested by vicb
[HttpFoundation] IPv6 support for RequestMatcher
[HttpFoundation] refactor RequestMatcherTest to use dataProvider
[Validator] use full iPv6 regex
[Validator] add IPv6 support to UrlValidator
[HttpFoundation] add IPv6 support to Request
[HttpFoundation] test Request::create with an IP as host name
[HttpFoundation] refactor Request::getClientIp test
* lsmith77/request_format_tweaks:
added text/html to default format mapping
return "q" from splitHttpAcceptHeader() to enable more complex accept header negotiations
added support for setting a custom default format in Request::getRequestFormat()
The Request constructor no longer uses values from PHP's super globals. If you want a Request populated with these values you must use the new static method Request::fromGlobals().
Your front controllers (i.e. web/app.php, web/app_dev.php ...) will need to be updated:
// old
$kernel->handle(new Request())->send();
// new
$kernel->handle(Request::fromGlobals())->send();
Original explanation from pull request:
I'm Using symfony2 with URL Rewriting to 'hide' index.php.
On form authentication, symfony2 redirect to http://host:port/index.php/login_path instead of http://host:port/login_path. I do understand that, in my case, redirect is set into one of :
FormAuthenticationEntryPoint with getUriForPath()
FormAuthenticationListener with getUriForPath()
Security/Firewal/ExceptionListener with getUri()
This path modify getUri and getUriForPath to :
remove default port from URI
remove script name if not initially present
The PHP native cache limiter feature has been disabled as this is now managed
by the HeaderBag class directly instead (see below.)
The HeaderBag class uses the following rules to define a sensible and
convervative default value for the Response 'Cache-Control' header:
* If no cache header is defined ('Cache-Control', 'ETag', 'Last-Modified',
and 'Expires'), 'Cache-Control' is set to 'no-cache';
* If 'Cache-Control' is empty, its value is set to "private, max-age=0,
must-revalidate";
* But if at least one 'Cache-Control' directive is set, and no 'public' or
'private' directives have been explicitely added, Symfony2 adds the
'private' directive automatically (except when 's-maxage' is set.)
So, remember to explicitly add the 'public' directive to 'Cache-Control' when
you want shared caches to store your application resources:
// The Response is private by default
$response->setEtag($etag);
$response->setLastModified($date);
$response->setMaxAge(10);
// Change the Response to be public
$response->setPublic();
// Set cache settings in one call
$response->setCache(array(
'etag' => $etag,
'last_modified' => $date,
'max_age' => 10,
'public' => true,
));
The idea of a string port is probably semantically wrong, but it actually follows the convention of at least some web servers ($_SERVER['SERVER_PORT'] is actually a string). And since the $port variable is used as a string in getHttpHost(), it's correct to allow the types not to match.
Some explanations on how it works now:
* The Session is an optional dependency of the Request. If you create the
Request yourself (which is mandatory now in the front controller) and if
you don't inject a Session yourself (which is recommended if you want the
session to be configured via dependency injection), the Symfony2 Kernel
will associate the Session configured in the Container with the Request
automatically.
* When duplicating a request, the session is shared between the parent and
the child (that's because duplicated requests are sub-requests of the main
one most of the time.) Notice that when you use ::create(), the behavior is
the same as for the constructor; no session is attached to the Request.
* Symfony2 tries hard to not create a session cookie when it is not needed
but a Session object is always available (the cookie is only created when
"something" is stored in the session.)
* Symfony2 only starts a session when:
* A session already exists in the request ($_COOKIE[session_name()] is
defined -- this is done by RequestListener);
* There is something written in the session object (the cookie will be sent
to the Client).
* Notice that reading from the session does not start the session anymore (as
we don't need to start a new session to get the default values, and because
if a session exists, it has already been started by RequestListener.)
