[2.1][HttpFoundation] Added some basic meta-data to Session
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
References the following tickets: #2171
Todo: -
Session data is stored as an encoded string against a single id. If we want to store meta-data about the session, that data has to be stored as part of the session data to ensure the meta-data can persist using any session save handler.
This patch makes it much easier to determine the logic of session expiration. In general a session expiry can be dealt with by the gc handlers, however, in some applications more specific expiry rules might be required.
Session expiry may also be more complex than a simple, session was idle for x seconds. For example, in Zikula there are three security settings, Low, Medium and High. The rules for session expiry are more complex as under the Medium setting, a session will expire after x minutes idle time, unless the rememberme option was ticked on login. If so, the session will not idle. This gives the user some control over their experience. Under the high security setting, then there is no option, sessions will expire after the idle time is reached and login the UI has the rememberme checkbox removed.
The other advantage is that under this methodology, there can be a UI experience on expiry, like "Sorry, your session expired due to being idle for 10 minutes".
Keeping in the spirit of Symfony2 Components, I am seeking to make session handling flexible enough to accommodate these general requirements without specifically covering expiration rules. It would mean that it would be up to the implementing application to specifcally check and expire session after starting it.
Expiration might look something like this:
$session->start();
if (time() - $session->getMetadataBag()->getLastUpdate() > $maxIdleTime) {
$session->invalidate();
throw new SessionExpired();
}
This commit also brings the ability to change the `cookie_lifetime` when migrating a session. This means one could move from a default of browser only session cookie to long-lived cookie when changing from a anonymous to a logged in user for example.
$session->migrate($destroy, $lifetime);

@fabpot - ping
This is a very important option which allows the cookie lifetime to be changed on migrate.
For example when a user converts from an anonymous session to a logged in session one might
wish to change from a persistent cookie to browser session (e.g. a banking application).
This commit allows applications to know certain meta-data about the session
Session storage is designed to only store some data against a session ID
so this method is necessary to be compatible with any session handler, including
native handlers.

Ref #3729

If you pre-flip your $validOptions arrays, you can use isset() instead of in_array() in the loop.
This changes the performance from O(m * n) to O(m).
---------------------------------------------------------------------------
by drak at 2012-03-30T11:53:24Z
@robocoder What is the expense of the array_flip though?
---------------------------------------------------------------------------
by robocoder at 2012-03-30T11:56:21Z
Why would you use array_flip if the array doesn't change? Change $validOptions = array('x', 'y', ...) to $validOptions = array('x' => 0, 'y' => 0, ...), then change the in_array() to use isset().
---------------------------------------------------------------------------
by stof at 2012-03-30T11:57:08Z
@drak a loop. But it will be done only once before the other loop so it will be O(n + m) instead of O(m * n)

[2.1][HttpFoundation] Multiple session flash messages
Bug fix: no
Feature addition: yes
Backwards compatibility break: yes, but this already happened in #2583. BC `Session` methods remain unbroken.
Symfony2 tests pass: yes
Fixes the following tickets: #1863
References the following tickets: #2714, #2753, #2510, #2543, #2853
Todo: -
This PR alters flash messages so that it is possible to store more than one message per flash type using the `add()` method or by passing an array of messages to `set()`.
__NOTES ABOUT BC__
This PR maintains BC behaviour with the `Session` class in that the old Symfony 2.0 methods will continue to work as before.

I think this is ready for review @fabpot @lsmith77
---------------------------------------------------------------------------
by lsmith77 at 2012-02-14T19:30:39Z
the FlashBag vs. AutoExpireFlashBag behavior and setup difference should probably also be explained in the upgrading log
---------------------------------------------------------------------------
by drak at 2012-02-15T04:43:14Z
@lsmith77 Those differences are explained already in the changelog
* Added `FlashBag`. Flashes expire when retrieved by `get()` or `all()`.
This makes the implementation ESI compatible.
* Added `AutoExpireFlashBag` (default) to replicate Symfony 2.0.x auto expire behaviour of messages auto expiring
after one page page load. Messages must be retrived by `get()` or `all()`.

Drak asked me to weigh in here with use cases. Drupal currently has a similar session-stored-messaging system in place that I'd like to be able to replace with Flash messages. We frequently have multiple messages within a single request, however, so this change is critical to our being able to do so.
For instance, when saving an article in Drupal there is, by default, a "yay, you saved an article!" type message that gets displayed. If you also have the site configured to send email when a post is updated, you may see a "email notifications sent" message (depending on your access level). If you have a Solr server setup for search, and you're in debug mode, there will also be a "record ID X added to Solr, it should update in 2 minutes" message. And if there's a bug somewhere, you'll also get, as an error message rather than notice message, a "Oops, E_NOTICE on line 54" message.
Form validation is another case. If you have multiple errors in a single form, we prefer to list all of them. So if you screw up 4 times on a form, you may get 4 different error messages showing what you screwed up so you can fix it in one go instead of several.
Now sure, one could emulate that by building a multi-message layer on top of single-layer messages, but, really, why? "One is a special case of many", and there are many many cases where you'll want to post multiple messages. Like, most of Drupal. :-)

@fabpot is there any information you still need before merging this? do you want more discussion in which case you might want to take this to the mailing list ..
---------------------------------------------------------------------------
by drak at 2012-03-08T18:54:13Z
Another plus for this PR is that it requires no extra lines of code in templates etc to display the flashes, see https://github.com/symfony/symfony/pull/3267/files#diff-1

Rebased against current `master`, should be mergeable again..

+1 to this, I have an extended version of HttpFoundation just for this... would love to get rid of it.

[HttpFoundation] SPL on ParameterBag
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
Added a couple SPL interfaces to ParameterBag, added shortcuts to working with the parameters. For example:
```php
<?php
$post = Request::createFromGlobal()->request;
echo "There are {count($post)} POST variables\n";
foreach ($post as $key => $val) {
echo "{$key}: {$val}\n";
}
```
Thoughts?
---------------------------------------------------------------------------
by stealth35 at 2012-03-07T13:09:11Z
You already have the `all` method
``` php
<?php
$post = Request::createFromGlobals()->request->all();
echo "There are ", count($post), " POST variables\n";
foreach ($post as $key => $val) {
echo "{$key}: {$val}\n";
}
```
---------------------------------------------------------------------------
by cboden at 2012-03-07T13:50:22Z
Yes, but when in the context of working with the Request object (or POST ParamegerBag), it's 1 more call and loose variable to set.
ParameterBag is a container, these common SPL interfaces give standard PHP container methods to it.
---------------------------------------------------------------------------
by lsmith77 at 2012-03-07T18:42:41Z
makes sense to me ..
---------------------------------------------------------------------------
by vicb at 2012-03-09T15:45:40Z
Probably makes sense. Could you check if any other `*Bag.php` needs to be updated so that it could ba an atomic merge.
---------------------------------------------------------------------------
by cboden at 2012-03-09T15:48:40Z
Whoops, good catch @vicb. I made a poor assumption all the *Bags extended ParameterBag, while only some do. I will post an update shortly.

Does Symfony (or any of its dependencies) has Redis support in any form whatsoever? If not this might be a good point to decide which clients to support
---------------------------------------------------------------------------
by lsmith77 at 2012-03-04T23:36:11Z
well ideally we just get this cache interface stuff done .. for this use case it would be perfect.
---------------------------------------------------------------------------
by pulzarraider at 2012-03-05T00:35:59Z
There is RedisProfilerStorage available (based on phpredis). I prefer and write code for [phpredis](https://github.com/nicolasff/phpredis).
It's recommended by [official Redis homepage](http://redis.io/clients#PHP). [In this benchmark](http://dev.af83.com/2011/01/01/which-php-library-to-use-with-redis-the-benchmark.html
) is fastest and less memory consumpting.
But if somebody prefer predis (with phpiredis), rediska or something other widely used, there are no limitations to add support of it to Symfony.
My opinion is, that the C extension should be supported at first, because of good performance and native session storage support. Redis is quite young and the process of creating PHP clients is comparable to Memcache.
There were created pure PHP Memcache clients in the past (Google found for example [this](http://www.phpclasses.org/browse/file/20284.html) and [this](http://code.blitzaffe.com/pages/phpclasses/files/memcached_client_52-12)), but they are not being used now. Everyone, who is seriously thinking about performance, is using only the C Redis/Memcache(d)/... extensions.
---------------------------------------------------------------------------
by drak at 2012-03-05T07:40:06Z
+1 on this PR. Needs a test written though.
I don't think there is any need to wait for #3493 imo. I'll deal with it if this is merged before #3493.
Are there any PHP ini settings for this for this driver or is everything via the `session.save_path` directive? (A quick look at the C code seems to indicate there are no explicit ini directives).
---------------------------------------------------------------------------
by lstrojny at 2012-03-05T12:14:34Z
@pulzarraider I don’t necessarily disagree with the usage of phpredis, I just wanted to bring up the issues of various clients and people having different preferences about them.
---------------------------------------------------------------------------
by fabpot at 2012-03-05T14:46:22Z
@pulzarraider Can you add some unit tests before I merge?
---------------------------------------------------------------------------
by pulzarraider at 2012-03-11T20:19:57Z
@drak No there are no php.ini settings. Only RedisArray has some, but it's another feature.
@fabpot I've added simple test based on other session storage tests.
I planned to create a RedisSessionStorage, too, but I have no time for it now. This can be added later in another PR as it's independent from NativeRedisSessionStorage.
