@bschussek: What's your opinion?
---------------------------------------------------------------------------
by stof at 2011-09-04T13:14:29Z
@hason could you rebase your branch on top of master and update the PR ?
You also need to change the messages in the constraint that uses the pluralization to a pluralized format.

@stof, @canni Rebased.
What is the best solution for the translation of messages?
1. Change messages in the classes and all xliff files?
2. Keep messages in the classes and change all xliff files?
---------------------------------------------------------------------------
by stof at 2012-02-09T08:19:41Z
The constraints contain the en message so you will need to modify them to update the message
---------------------------------------------------------------------------
by hason at 2012-02-09T08:55:55Z
I prefer second option. The Validator component should be decoupled from the Translation component. The constraints contain the en message which is also the key for Translation component. We should create validators.en.xlf in the FrameworkBundle for en message. I think that this is better solution. What do you think?

[Form] Moved logic of addXxx()/removeXxx() methods to the PropertyPath class
Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: #3732
Todo: -
The addXxx()/removeXxx() methods should now be called correctly in ChoiceType and CollectionType.
PropertyPath now favors addXxx()/removeXxx() over setXxx() for collections. For example:
```
$propertyPath = new PropertyPath('article.tags');
// Tries to use addTag()/removeTag() and only uses setTags() (et al.)
// if not found
$propertyPath->setValue($article, $tags);
```
For other languages than English or very irregular plurals, a custom singular can be set by separating it with a pipe:
```
$propertyPath = new PropertyPath('article.genera|genus');
```

---------------------------------------------------------------------------
by stof at 2012-04-10T14:46:47Z
well, doesn't it require changes to the description of previous changes related to the ChoiceList ? It does in the UPGRADE file so it is weird if the CHANGELOG does not require any change.
---------------------------------------------------------------------------
by bschussek at 2012-04-10T14:56:05Z
Feel free to check yourself :)
Setting a property path like "article.tags" will now automatically try to
favor addTag() and removeTag() over setTags(), if found. If you want to
set up a property path with an irregular singular that is not detected,
you can use "|" to separate the plural from the singular form in the
path: "article.genera|genus".
Another consequence of this commit is that the MergeCollectionListener has
been simplified a lot. Forms returning an array or a collection will
always result in adders/removers being called now without having to add
this listener.

[2.1][HttpFoundation] Refactor session handling and flash messages
Bug fix: yes
Feature addition: yes
Backwards compatibility break: yes
Symfony2 tests pass: yes
Fixes the following tickets: #2607, #2591, #2717, #2773
References the following tickets: #2592, #2543, #2541, #2510, #2714, #2684
Todo: -
__Introduction__
This extensive PR is a refactor with minimal BC breaks of the `[HttpFoundation]` component's session management which fixes several issues in the current implementation. This PR includes all necessary changes to other bundles and components is documented in the `CHANGELOG-2.1` and `UPGRADING-2.1`.
__Summary of Changes__
__Session:__
- Session object now implements `SessionInterface`
__Attributes:__
- Attributes now handled by `AttributeBagInterface`
- Added two AttributeBag implementations: `AttributeBag` replicates the current Symfony2 attributes behaviour, and the second, `NamespacedAttributeBag` introduces structured namespaced representation using '/' in the key. Both are BC. `FrameworkBundle` defaults to the old behaviour.
__Flash messages:__
- Flash messages now handled by `FlashBagInterface`
- Introduced `FlashBag` which changes the way flash messages expire, they now expire on use rather than automatically, useful for ESI.
- Introduced `AutoExpireFlashBag` (default) which replicates the old automatic expiry behaviour of flash messages.
__Session Storage:__
- Introduced a base object, `AbstractSessionStorage` for session storage drivers
- Introduced a `SessionSaveHandlerInterface` when using custom session save handlers
- Introduced a `NullSessionStorage` driver which allows for unsaved sessions
- Introduced new session storage drivers for Memcache and Memcached
- Introduced new session storage drivers for PHP's native SQLite, Memcache and Memcached support
__General:__
- Fixed bugs where session attributes are not saved and all cases where flash messages would get lost
- Wrote new tests, refactored related existing tests and increased test coverage extensively.
__Rationale/Details__
I'll explain more detail in the following sections.
__Unit Tests__
All unit and functional tests pass.
__Note on Functional Testing__
I've introduced `MockFileSessionStorage` which replaces `FilesystemSessionStorage` to emulate a PHP session for functional testing. Essentially the same methodology of functional testing has been maintained but without interrupting the other session storage drivers interaction with real PHP sessions. The service is now called `session.storage.mock_file`.
__Session Workflow__
PHP sessions follow a specific workflow which is not being followed by the current session management implementation and is responsible for some unpredictable bugs and behaviours.
Basically, PHP session workflow is as follows: `open`, `read`, `write`, `close`. In between these can occur, `destroy` and `garbage collection`. These actions are handled by `session save handlers` and one is always registered in all cases. By default, the `files` save handler (internally to PHP) is registered by PHP at the start of code execution.
PHP offers the possibility to change the save handler to another internal type, for example one provided by a PHP extension (think SQLite, Memcache etc), or you can register a user type and set your own handlers. However __in all cases__ PHP requires the handlers.
The handlers are called when the following things occur:
- `open` and `read` when `session_start()` or the session autostarts when PHP outputs some display
- `destroy` when `session_regenerate_id(true)` is called
- `write` and `close` when PHP shuts down or when `session_write_close()` is called
- `garbage collection` is called randomly according to configurable probability
The next very important aspect of this PR is that `$_SESSION` plays an important part in this workflow because the contents of the $_SESSION is populated __after__ the `read` handler returns the previously saved serialised session data. The `write` handler is sent the serialised `$_SESSION` contents for save. Please note the serialisation is a different format to `serialize()`.
For this reason, any session implementation cannot get rid of using `$_SESSION`.
I wrote more details on this issue [here](https://github.com/symfony/symfony/issues/2607#issuecomment-2858300)
In order to make writing session storage drivers simple, I created a light base class `AbstractSessionStorage` and the `SessionSaveHandlerInterface` which allows you to quickly write native and custom save handler drivers.
__Flash Messages [BC BREAK]__
Flash messages currently allow representation of a single message per `$name`. Fabien designed the original system so that `$name` was equivalent to flash message type. The current PR changes the fact that Flash messages expire explicitly when retrieved for display to the user as opposed to immediately on the next page load.
The last issue fixes potential cases when flash messages are lost due to an unexpected intervening page-load (an error for example). The API `get()` has a flag which allows you to override the `clear()` action.
__Flash message translation__
This PR does not cover translation of flash messages because messages should be translated before calling the flash message API. This is because flash messages are used to present messages to the user after a specific action, and in any case, immediately on the next page load. Since we know the locale of the request in every case we can translate the message before storing. Secondly, translation is simply a string manipulation. Translation API calls should always have the raw untranslated string present because it allows for extraction of translation catalogs. For a complete answer see my answer [here](https://github.com/symfony/symfony/pull/2543#issuecomment-2858707)
__Session attribute and structured namespacing__
__This has been implemented without changing the current default behaviour__ but details are below for the alternative:
Attributes are currently stored in a flat array which limits the potential of session attributes:
Here are some examples to see why this 'structured namespace' methodology is extremely convenient over using a flat system. Let's look at an example with csrf tokens. Let's say we have multiple csrftokens stored by form ID (allowing multiple forms on the page and tabbed browsing).
If we're using a flat system, you might have
'tokens' => array('a' => 'a6c1e0b6',
'b' => 'f4a7b1f3')
With a flat system when you get the key `tokens`, you will get back an array, so now you have to analyse the array. So if you simply want to add another token, you have to follow three steps: get the session attribute `tokens`, have to add to the array, and lastly set the entire array back to the session.
$tokens = $session->get('tokens');
$tokens['c'] = $value;
$session->set('tokens', $tokens);
Doable, but you can see it's pretty long winded.
With structured namespacing you can simply do:
$session->set('c', $value, '/tokens');
There are several ways to implement this, either with an additional `$namespace` argument, or by treating a character in the `$key` as a namespacer. `NamespacedAttributeBag` treats `/` as a namespacer so you can represent `user.tokens/a` for example. The namespace character is configurable in `NamespacedAttributeBag`.

by lsmith77 at 2011-12-19T16:01:19Z
@deviantintegral could you look over this to see if it really addresses everything you wanted with PR #2510 ?
---------------------------------------------------------------------------
by deviantintegral at 2011-12-24T20:12:03Z
I've read through the documentation and upgrade notes, and I can't see anything that's obviously missing from #2510. Being able to support multiple flashes per type is the most important, and the API looks reasonable to me. Drupal does support supressing repeat messages, but that can easily be implemented in our code unless there's a compelling case for it to be a part of Symfony.
I wonder if PHP memcache support is required in Symfony given the availability of memcached. I'm not familiar with how other parts of Symfony handle it, but there is often quite a bit of confusion between the two PHP extensions. It could be simpler to remove one, or add a bit of info describing or linking to why there are two nearly identical classes.
Is it possible to make one class inherit from the other (memcached is a child of memcache)?
---------------------------------------------------------------------------
by Fristi at 2011-12-24T20:29:46Z
Interesting, maybe add: session events as I did with the current impl: https://github.com/Fristi/SessionBundle
---------------------------------------------------------------------------
by drak at 2011-12-25T00:50:03Z
@deviantintegral - I agree about the confusion between memcache and memcached but actually, it is necessary to support both because `memcached` is not available everywhere. For example on Debian Lenny and RHEL/CentOS 5, only memcache is available by default. This would preclude a massive amount of shared hosting environments. Also, it is not possible to inherit one from the other, they are completely different drivers.
@Fristi - I also thought about the events, but they do not belong as part of the standalone component as this would create a coupling to the event dispatcher. The way you have done it, ie, in a bundle is the right way to achieve it.

by lsmith77 at 2012-01-02T15:00:00Z
@fabpot did you have time to review this yet? with all the work @drak has done its important that he gets some feedback soon. its clear this PR breaks BC in ways we never wanted to allow. but i think this PR also clearly explains why its necessary none the less.
---------------------------------------------------------------------------
by drak at 2012-01-02T15:41:53Z
@fabpot - I have removed the WIP status from this PR now and rebased against the current master branch.
---------------------------------------------------------------------------
by Tobion at 2012-01-07T07:13:38Z
From what I read from the IRC chat logs, the main concern of @fabpot is whether we really need multiple flash messages per type. I'm in favor of this PR and just want to add one point to this discussion.
At the moment you can add multiple flash messages of different type/category/identifier. For example you can specify one error message and one info message after an operation. I think most agree that this can be usefull.
But then it makes semantically no sense that you currently cannot add 2 info messages. This approach feels a bit half-done.
So I think this PR eliminates this paradox.
---------------------------------------------------------------------------
by drak at 2012-01-07T09:11:07Z
For reference there is also a discussion started by @lsmith77 on the mailing list at https://groups.google.com/forum/#!topic/symfony-devs/cy4wokD0mQI
---------------------------------------------------------------------------
by dlsniper at 2012-01-07T16:02:15Z
@drak I could also add the next scenario that I currently have to live with, in addition to @lsmith77 ones.
I had this issue while working on our shopping cart implementation for a customer where the customer wanted to show the unavailability of the items as different lines in the 'flash-error' section of the cart. We had to set an array as the 'flash message' in order to display that information.
So in this case for example having the flash messages types as array would actually make more sense that sending an array to the flasher. Plus the the other issue we had was that we also wanted to add another error in the message but we had to do a check to see if the flash message is an array already or we need to make it an array.
I think it's better not to impose a limit of this sort and let the users be able to handle every scenario, even if some are rare, rather that forcing users to overcome limitations such as these.
I really hope this PR gets approved faster and thanks everyone for their hard work :)
---------------------------------------------------------------------------
by Tobion at 2012-01-07T21:01:07Z
@dlsniper I think you misinterpreted my point.

by fabpot at 2012-02-01T14:58:23Z
To be clear, I've asked to split this PR in two parts:
* one about the session refactoring (which is non-controversial and should be merged ASAP)
* this one with only the flash refactoring
---------------------------------------------------------------------------
by drak at 2012-02-02T11:29:26Z
@fabpot this is ready to be merged now. I will open a separate PR later today for the flash messages as a bucket.
---------------------------------------------------------------------------
by fabpot at 2012-02-02T11:34:39Z
I must have missed something, but I still see a lot of changes related to the flash messages.
---------------------------------------------------------------------------
by drak at 2012-02-02T11:39:10Z
When I spoke to you you said you wanted to make the commit with flash messages with one message per name/type rather than multiple. The old flash messages behaviour is 100% maintained in `AutoExpireFlashBag` which can be the default in the framework if you wish. The `FlashBag` implementation makes Symfony2 ESI compatible.
---------------------------------------------------------------------------
by stof at 2012-02-02T11:47:38Z
@drak splitting into 2 PRs means you should not refactor the flash messages in this one but in the dedicated one.
---------------------------------------------------------------------------
by drak at 2012-02-02T12:29:43Z
@stof Yes. I discussed with Fabien over chat there are basically no changes
to flashes in `FlashBag` and `AutoExpireFlashBag` maintains the exact
behaviour as before. The FlashBag just introduces ESI compatible flashes.
There is no way to refactor the sessions without moving the flash messages
to their own bag. The next PR will propose the changes to flashes that
allow multiple messages per name/type. I can size the PR down a little
more removing the new storage drivers and so on to make the PR smaller but
that's really as far as I can go. To be clear, while the API has changed a
little for flashes, the behaviour is the same.

Fixed exception that was thrown when doing:

On a side note, the options passed to `FieldType::getDefaultOptions` now always also contain the default options of any parent types. This is necessary if you want to be independent of how `getDefaultOptions` is implemented in the parent type and still rely on the already defined values.
As a result, `FieldType::getParent` doesn't see default options anymore. This shouldn't be a big problem, because this method only relies on options in few cases. If it does, options now need to be checked for existence with `isset` before being used (BC break).

Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: #1540
Todo: adapt documentation
Adds functionality for calling `addXxx` and `removeXxx` method in your model. All types returning a collection of values are affected: "collection", "choice" (with multiple selection) and "entity" (with multiple selection).
Example:
class Article
{
public function addTag($tag) { ... }
public function removeTag($tag) { ... }
public function getTags($tag) { ... }
}
And the controller:
$form = $this->createFormBuilder($article)
->add('tags')
->getForm();
Upon modifying the form, addTag() and removeTag() are now called appropiately.

Really great

Great !!
Two suggestions:
* make "add" and "remove" configurable,
* introduce a base class for the remove listeners with (final?) `::getSubscribedEvents()` and `::getEventPriorities()`

Can wait to have it!
It will save lots of time trying to solve WTF effects and making workarounds.

@vicb: Your first point is done. The second, I don't understand.

@bschussek your branch conflicts with master according to github
---------------------------------------------------------------------------

@bschussek my point is that I can stand hard-coded priorities which are error prone. A better solution might be to introduce constants (in `FormEvents` / `FormEventPriorities` ?) with meaningful names.

@stof Rebased
@vicb I know, but who is responsible for managing priorities? There is no central entitty that can do this. (btw this is a general problem of the priority system of the EventDispatcher)
@fabpot Ready to merge.

@bschussek doesn't each form has is own dispatcher so there is no need for a global registry here, something local to the form could be good enough.
