made FileBinaryMimeTypeGuesser command configurable
added Request::getUser() and Request::getPassword()
added support for the PATCH method in Request
removed the ContentTypeMimeTypeGuesser class as it is deprecated and never used on PHP 5.3
made mimetype to extension conversion configurable
[BC BREAK] Moved all session related classes and interfaces into own namespace, as
Symfony\Component\HttpFoundation\Session and renamed classes accordingly.
Session handlers are located in the subnamespace Symfony\Component\HttpFoundation\Session\Handler.
SessionHandlers must implement \SessionHandlerInterface or extend from the
Symfony\Component\HttpFoundation\Storage\Handler\NativeSessionHandler base class.
Added internal storage driver proxy mechanism for forward compatibility with
PHP 5.4 \SessionHandler class.
Added session handlers for custom Memcache, Memcached and Null session save handlers.
[BC BREAK] Removed NativeSessionStorage and replaced with NativeFileSessionHandler.
[BC BREAK] SessionStorageInterface methods removed: write(), read() and
remove(). Added getBag(), registerBag(). The NativeSessionStorage class
is a mediator for the session storage internals including the session handlers
which do the real work of participating in the internal PHP session workflow.
[BC BREAK] Introduced mock implementations of SessionStorage to enable unit
and functional testing without starting real PHP sessions. Removed
ArraySessionStorage, and replaced with MockArraySessionStorage for unit
tests; removed FilesystemSessionStorage, and replaced withMockFileSessionStorage
for functional tests. These do not interact with global session ini
configuration values, session functions or $_SESSION superglobal. This means
they can be configured directly allowing multiple instances to work without
conflicting in the same PHP process.
[BC BREAK] Removed the close() method from the Session class, as this is
now redundant.
Deprecated the following methods from the Session class: setFlash(), setFlashes()getFlash(), hasFlash(), and removeFlash(). Use getFlashBag() instead
which returns a FlashBagInterface.
Session->clear() now only clears session attributes as before it cleared
flash messages and attributes. Session->getFlashBag()->all() clears flashes now.
Session data is now managed by SessionBagInterface to better encapsulate
session data.
Refactored session attribute and flash messages system to their own
SessionBagInterface implementations.
Added FlashBag. Flashes expire when retrieved by get() or all(). This
implementation is ESI compatible.
Added AutoExpireFlashBag (default) to replicate Symfony 2.0.x auto expire
behavior of messages auto expiring after one page page load. Messages must
be retrieved by get() or all().
Added Symfony\Component\HttpFoundation\Attribute\AttributeBag to replicate
attributes storage behavior from 2.0.x (default).
Added Symfony\Component\HttpFoundation\Attribute\NamespacedAttributeBag for
namespace session attributes.
Flash API can stores messages in an array so there may be multiple messages
per flash type. The old Session class API remains without BC break as it
will allow single messages as before.
Added basic session meta-data to the session to record session create time,
last updated time, and the lifetime of the session cookie that was provided
to the client.
Request::getClientIp() method doesn't take a parameter anymore but bases
itself on the trustProxy parameter.
Added isMethod() to Request object.
[BC BREAK] The methods getPathInfo(), getBaseUrl() and getBasePath() of
a Request now all return a raw value (vs a urldecoded value before). Any call
to one of these methods must be checked and wrapped in a rawurldecode() if
needed.
