+## Changelog
+
+### 1.3.0
+
+This release introduces a PHP version bump. `doctrine/annotations` now requires PHP
+5.6 or later to be installed.
+
+A series of additional improvements have been introduced:
+
+ * support for PHP 7 "grouped use statements"
+ * support for ignoring entire namespace names
+   via `Doctrine\Common\Annotations\AnnotationReader::addGlobalIgnoredNamespace()` and
+   `Doctrine\Common\Annotations\DocParser::setIgnoredAnnotationNamespaces()`. This will
+   allow you to ignore annotations from namespaces that you cannot autoload
+ * testing all parent classes and interfaces when checking if the annotation cache
+   in the `CachedReader` is fresh
+ * simplifying the cache keys used by the `CachedReader`: keys are no longer artificially
+   namespaced, since `Doctrine\Common\Cache` already supports that
+ * corrected parsing of multibyte strings when `mbstring.func_overload` is enabled
+ * corrected parsing of annotations when `"\t"` is put before the first annotation
+   in a docblock
+ * allow skipping non-imported annotations when a custom `DocParser` is passed to
+   the `AnnotationReader` constructor
+

+# Upgrade to 1.4
+
+## Minor BC Break: `Doctrine\Common\Cache\FileCache#$extension` is now `private`.
+
+If you need to override the value of `Doctrine\Common\Cache\FileCache#$extension`, then use the
+second parameter of `Doctrine\Common\Cache\FileCache#__construct()` instead of overriding
+the property in your own implementation.
+
+## Minor BC Break: file based caches paths changed
+
+`Doctrine\Common\Cache\FileCache`, `Doctrine\Common\Cache\PhpFileCache` and
+`Doctrine\Common\Cache\FilesystemCache` are using a different cache paths structure.
+
+If you rely on warmed up caches for deployments, consider that caches generated
+with `doctrine/cache` `<1.4` are not compatible with the new directory structure,
+and will be ignored.

+# Doctrine Collections
+
+[![Build Status](https://travis-ci.org/doctrine/collections.svg?branch=master)](https://travis-ci.org/doctrine/collections)
+
+Collections Abstraction library
+
+## Changelog
+
+### v1.3.0
+
+* [Explicit casting of first and max results in criteria API](https://github.com/doctrine/collections/pull/26)
+* [Keep keys when using `ArrayCollection#matching()` with sorting](https://github.com/doctrine/collections/pull/49)
+* [Made `AbstractLazyCollection#$initialized` protected for extensibility](https://github.com/doctrine/collections/pull/52)
+
+### v1.2.0
+
+* Add a new ``AbstractLazyCollection``
+
+### v1.1.0
+
+* Deprecated ``Comparison::IS``, because it's only there for SQL semantics.
+  These are fixed in the ORM instead.
+* Add ``Comparison::CONTAINS`` to perform partial string matches:
+
+        $criteria->andWhere($criteria->expr()->contains('property', 'Foo'));

+ * The missing (SPL) Collection/Array/OrderedMap interface.
+ *
+ * A Collection resembles the nature of a regular PHP array. That is,
+ * it is essentially an <b>ordered map</b> that can also be used
+ * like a list.
+ *
+ * A Collection has an internal iterator just like a PHP array. In addition,
+ * a Collection can be iterated with external iterators, which is preferable.
+ * To use an external iterator simply use the foreach language construct to
+ * iterate over the collection (which calls {@link getIterator()} internally) or
+ * explicitly retrieve an iterator though {@link getIterator()} which can then be
+ * used to iterate over the collection.
+ * You can not rely on the internal iterator of the collection being at a certain
+ * position unless you explicitly positioned it before. Prefer iteration with
+ * external iterators.

+This document details all the possible changes that you should investigate when updating
+your project from Doctrine Common 2.0.x to 2.1
+
+## AnnotationReader changes
+
+The annotation reader was heavily refactored between 2.0 and 2.1-RC1. In theory the operation of the new reader should be backwards compatible, but it has to be setup differently to work that way:
+
+    $reader = new \Doctrine\Common\Annotations\AnnotationReader();
+    $reader->setDefaultAnnotationNamespace('Doctrine\ORM\Mapping\\');
+    // new code necessary starting here
+    $reader->setIgnoreNotImportedAnnotations(true);
+    $reader->setEnableParsePhpImports(false);
+    $reader = new \Doctrine\Common\Annotations\CachedReader(
+        new \Doctrine\Common\Annotations\IndexedReader($reader), new ArrayCache()
+    );
+
+## Annotation Base class or @Annotation
+
+Beginning after 2.1-RC2 you have to either extend ``Doctrine\Common\Annotations\Annotation`` or add @Annotation to your annotations class-level docblock, otherwise the class will simply be ignored.
+
+## Removed methods on AnnotationReader
+
+* AnnotationReader::setAutoloadAnnotations()
+* AnnotationReader::getAutoloadAnnotations()
+* AnnotationReader::isAutoloadAnnotations()
+
+## AnnotationRegistry
+
+Autoloading through the PHP autoloader is removed from the 2.1 AnnotationReader. Instead you have to use the global AnnotationRegistry for loading purposes:
+
+    \Doctrine\Common\Annotations\AnnotationRegistry::registerFile($fileWithAnnotations);
+    \Doctrine\Common\Annotations\AnnotationRegistry::registerAutoloadNamespace($namespace, $dirs = null);
+    \Doctrine\Common\Annotations\AnnotationRegistry::registerAutoloadNamespaces($namespaces);
+    \Doctrine\Common\Annotations\AnnotationRegistry::registerLoader($callable);
+
+The $callable for registering a loader accepts a class as first and only parameter and must try to silently autoload it. On success true has to be returned.
+The registerAutoloadNamespace function registers a PSR-0 compatible silent autoloader for all classes with the given namespace in the given directories.
+If null is passed as directory the include path will be used.

+This document details all the possible changes that you should investigate when 
+updating your project from Doctrine Common 2.1 to 2.2:
+
+## Annotation Changes
+
+- AnnotationReader::setIgnoreNotImportedAnnotations has been removed, you need to 
+  add ignore annotation names which are supposed to be ignored via
+  AnnotationReader::addGlobalIgnoredName
+  
+- AnnotationReader::setAutoloadAnnotations was deprecated by the AnnotationRegistry
+  in 2.1 and has been removed in 2.2
+
+- AnnotationReader::setEnableParsePhpImports was added to ease transition to the new
+  annotation mechanism in 2.1 and is removed in 2.2
+
+- AnnotationReader::isParsePhpImportsEnabled is removed (see above)
+
+- AnnotationReader::setDefaultAnnotationNamespace was deprecated in favor of explicit
+  configuration in 2.1 and will be removed in 2.2 (for isolated projects where you
+  have full-control over _all_ available annotations, we offer a dedicated reader
+  class ``SimpleAnnotationReader``)
+
+- AnnotationReader::setAnnotationCreationFunction was deprecated in 2.1 and will be
+  removed in 2.2. We only offer two creation mechanisms which cannot be changed
+  anymore to allow the same reader instance to work with all annotations regardless
+  of which library they are coming from.
+  
+- AnnotationReader::setAnnotationNamespaceAlias was deprecated in 2.1 and will be
+  removed in 2.2 (see setDefaultAnnotationNamespace)
+
+- If you use a class as annotation which has not the @Annotation marker in it's 
+  class block, we will now throw an exception instead of silently ignoring it. You
+  can however still achieve the previous behavior using the @IgnoreAnnotation, or
+  AnnotationReader::addGlobalIgnoredName (the exception message will contain detailed
+  instructions when you run into this problem).
+
+## Cache Changes
+  
+- Renamed old AbstractCache to CacheProvider
+
+- Dropped the support to the following functions of all cache providers:
+
+ - CacheProvider::deleteByWildcard
+
+ - CacheProvider::deleteByRegEx
+
+ - CacheProvider::deleteByPrefix
+
+ - CacheProvider::deleteBySuffix
+
+- CacheProvider::deleteAll will not remove ALL entries, it will only mark them as invalid
+
+- CacheProvider::flushAll will remove ALL entries, namespaced or not
+
+- Added support to MemcachedCache
+
+- Added support to WincacheCache
+
+## ClassLoader Changes
+
+- ClassLoader::fileExistsInIncludePath() no longer exists. Use the native stream_resolve_include_path() PHP function

+/**
+ * PersistentObject base class that implements getter/setter methods for all mapped fields and associations
+ * by overriding __call.
+ *
+ * This class is a forward compatible implementation of the PersistentObject trait.
+ *
+ * Limitations:
+ *
+ * 1. All persistent objects have to be associated with a single ObjectManager, multiple
+ *    ObjectManagers are not supported. You can set the ObjectManager with `PersistentObject#setObjectManager()`.
+ * 2. Setters and getters only work if a ClassMetadata instance was injected into the PersistentObject.
+ *    This is either done on `postLoad` of an object or by accessing the global object manager.
+ * 3. There are no hooks for setters/getters. Just implement the method yourself instead of relying on __call().
+ * 4. Slower than handcoded implementations: An average of 7 method calls per access to a field and 11 for an association.
+ * 5. Only the inverse side associations get autoset on the owning side as well. Setting objects on the owning side
+ *    will not set the inverse side associations.
+ *
+ * @example
+ *
+ *  PersistentObject::setObjectManager($em);
+ *
+ *  class Foo extends PersistentObject
+ *  {
+ *      private $id;
+ *  }
+ *
+ *  $foo = new Foo();
+ *  $foo->getId(); // method exists through __call

+Security
+========
+
+The Doctrine library is operating very close to your database and as such needs
+to handle and make assumptions about SQL injection vulnerabilities.
+
+It is vital that you understand how Doctrine approaches security, because
+we cannot protect you from SQL injection.
+
+Please read the documentation chapter on Security in Doctrine DBAL to
+understand the assumptions we make.

+# Upgrade to 2.5.1
+
+## MINOR BC BREAK: Doctrine\DBAL\Schema\Table
+
+When adding indexes to ``Doctrine\DBAL\Schema\Table`` via ``addIndex()`` or ``addUniqueIndex()``,
+duplicate indexes are not silently ignored/dropped anymore (based on semantics, not naming!).
+Duplicate indexes are considered indexes that pass ``isFullfilledBy()`` or ``overrules()``
+in ``Doctrine\DBAL\Schema\Index``.
+This is required to make the index renaming feature introduced in 2.5.0 work properly and avoid
+issues in the ORM schema tool / DBAL schema manager which pretends users from updating
+their schemas and migrate to DBAL 2.5.*.
+Additionally it offers more flexibility in declaring indexes for the user and potentially fixes
+related issues in the ORM.
+With this change, the responsibility to decide which index is a "duplicate" is completely deferred
+to the user.
+Please also note that adding foreign key constraints to a table via ``addForeignKeyConstraint()``,
+``addUnnamedForeignKeyConstraint()`` or ``addNamedForeignKeyConstraint()`` now first checks if an
+appropriate index is already present and avoids adding an additional auto-generated one eventually.
+
+# Upgrade to 2.5
+
+## BC BREAK: time type resets date fields to UNIX epoch
+
+When mapping `time` type field to PHP's `DateTime` instance all unused date fields are
+reset to UNIX epoch (i.e. 1970-01-01). This might break any logic which relies on comparing
+`DateTime` instances with date fields set to the current date.
+
+Use `!` format prefix (see http://php.net/manual/en/datetime.createfromformat.php) for parsing
+time strings to prevent having different date fields when comparing user input and `DateTime`
+instances as mapped by Doctrine.
+
+## BC BREAK: Doctrine\DBAL\Schema\Table
+
+The methods ``addIndex()`` and ``addUniqueIndex()`` in ``Doctrine\DBAL\Schema\Table``
+have an additional, optional parameter. If you override these methods, you should
+add this new parameter to the declaration of your overridden methods.
+
+## BC BREAK: Doctrine\DBAL\Connection
+
+The visibility of the property ``$_platform`` in ``Doctrine\DBAL\Connection``
+was changed from protected to private. If you have subclassed ``Doctrine\DBAL\Connection``
+in your application and accessed ``$_platform`` directly, you have to change the code
+portions to use ``getDatabasePlatform()`` instead to retrieve the underlying database
+platform.
+The reason for this change is the new automatic platform version detection feature,
+which lazily evaluates the appropriate platform class to use for the underlying database
+server version at runtime.
+Please also note, that calling ``getDatabasePlatform()`` now needs to establish a connection
+in order to evaluate the appropriate platform class if ``Doctrine\DBAL\Connection`` is not
+already connected. Under the following circumstances, it is not possible anymore to retrieve
+the platform instance from the connection object without having to do a real connect:
+
+1. ``Doctrine\DBAL\Connection`` was instantiated without the ``platform`` connection parameter.
+2. ``Doctrine\DBAL\Connection`` was instantiated without the ``serverVersion`` connection parameter.
+3. The underlying driver is "version aware" and can provide different platform instances
+   for different versions.
+4. The underlying driver connection is "version aware" and can provide the database server
+   version without having to query for it.
+
+If one of the above conditions is NOT met, there is no need for ``Doctrine\DBAL\Connection``
+to do a connect when calling ``getDatabasePlatform()``.
+
+## datetime Type uses date_create() as fallback
+
+Before 2.5 the DateTime type always required a specific format, defined in
+`$platform->getDateTimeFormatString()`, which could cause quite some troubles
+on platforms that had various microtime precision formats. Starting with 2.5
+whenever the parsing of a date fails with the predefined platform format,
+the `date_create()` function will be used to parse the date.
+
+This could cause some troubles when your date format is weird and not parsed
+correctly by `date_create`, however since databases are rather strict on dates
+there should be no problem.
+
+## Support for pdo_ibm driver removed
+
+The ``pdo_ibm`` driver is buggy and does not work well with Doctrine. Therefore it will no
+longer be supported and has been removed from the ``Doctrine\DBAL\DriverManager`` drivers
+map. It is highly encouraged to to use `ibm_db2` driver instead if you want to connect
+to an IBM DB2 database as it is much more stable and secure.
+
+If for some reason you have to utilize the ``pdo_ibm`` driver you can still use the `driverClass`
+connection parameter to explicitly specify the ``Doctrine\DBAL\Driver\PDOIbm\Driver`` class.
+However be aware that you are doing this at your own risk and it will not be guaranteed that
+Doctrine will work as expected.
+
+# Upgrade to 2.4
+
+## Doctrine\DBAL\Schema\Constraint
+
+If you have custom classes that implement the constraint interface, you have to implement
+an additional method ``getQuotedColumns`` now. This method is used to build proper constraint
+SQL for columns that need to be quoted, like keywords reserved by the specific platform used.
+The method has to return the same values as ``getColumns`` only that those column names that
+need quotation have to be returned quoted for the given platform.
+
+# Upgrade to 2.3
+
+## Oracle Session Init now sets Numeric Character
+
+Before 2.3 the Oracle Session Init did not care about the numeric character of the Session.
+This could lead to problems on non english locale systems that required a comma as a floating
+point seperator in Oracle. Since 2.3, using the Oracle Session Init on connection start the
+client session will be altered to set the numeric character to ".,":
+
+    ALTER SESSION SET NLS_NUMERIC_CHARACTERS = '.,'
+
+See [DBAL-345](http://www.doctrine-project.org/jira/browse/DBAL-345) for more details.
+
+## Doctrine\DBAL\Connection and Doctrine\DBAL\Statement
+
+The query related methods including but not limited to executeQuery, exec, query, and executeUpdate
+now wrap the driver exceptions such as PDOException with DBALException to add more debugging
+information such as the executed SQL statement, and any bound parameters.
+
+If you want to retrieve the driver specific exception, you can retrieve it by calling the
+``getPrevious()`` method on DBALException.
+
+Before:
+
+    catch(\PDOException $ex) {
+        // ...
+    }
+
+After:
+
+    catch(\Doctrine\DBAL\DBALException $ex) {
+        $pdoException = $ex->getPrevious();
+        // ...
+    }
+
+## Doctrine\DBAL\Connection#setCharsetSQL() removed
+
+This method only worked on MySQL and it is considered unsafe on MySQL to use SET NAMES UTF-8 instead
+of setting the charset directly on connection already. Replace this behavior with the
+connection charset option:
+
+Before:
+
+    $conn = DriverManager::getConnection(array(..));
+    $conn->setCharset('UTF8');
+
+After:
+
+    $conn = DriverManager::getConnection(array('charset' => 'UTF8', ..));
+
+## Doctrine\DBAL\Schema\Table#renameColumn() removed
+
+Doctrine\DBAL\Schema\Table#renameColumn() was removed, because it drops and recreates
+the column instead. There is no fix available, because a schema diff
+cannot reliably detect if a column was renamed or one column was created
+and another one dropped.
+
+You should use explicit SQL ALTER TABLE statements to change columns names.
+
+## Schema Filter paths
+
+The Filter Schema assets expression is not wrapped in () anymore for the regexp automatically.
+
+Before:
+
+    $config->setFilterSchemaAssetsExpression('foo');
+
+After:
+
+    $config->setFilterSchemaAssetsExpression('(foo)');
+
+## Creating MySQL Tables now defaults to UTF-8
+
+If you are creating a new MySQL Table through the Doctrine API, charset/collate are
+now set to 'utf8'/'utf8_unicode_ci' by default. Previously the MySQL server defaults were used.
+
+# Upgrade to 2.2
+
+## Doctrine\DBAL\Connection#insert and Doctrine\DBAL\Connection#update
+
+Both methods now accept an optional last parameter $types with binding types of the values passed.
+This can potentially break child classes that have overwritten one of these methods.
+
+## Doctrine\DBAL\Connection#executeQuery
+
+Doctrine\DBAL\Connection#executeQuery() got a new last parameter "QueryCacheProfile $qcp"
+
+## Doctrine\DBAL\Driver\Statement split
+
+The Driver statement was split into a ResultStatement and the normal statement extending from it.
+This separates the configuration and the retrieval API from a statement.
+
+## MsSql Platform/SchemaManager renamed
+
+The MsSqlPlatform was renamed to SQLServerPlatform, the MsSqlSchemaManager was renamed
+to SQLServerSchemaManager.
+
+## Cleanup SQLServer Platform version mess
+
+DBAL 2.1 and before were actually only compatible to SQL Server 2008, not earlier versions.
+Still other parts of the platform did use old features instead of newly introduced datatypes
+in SQL Server 2005. Starting with DBAL 2.2 you can pick the Doctrine abstraction exactly
+matching your SQL Server version.
+
+The PDO SqlSrv driver now uses the new `SQLServer2008Platform` as default platform.
+This platform uses new features of SQL Server as of version 2008. This also includes a switch
+in the used fields for "text" and "blob" field types to:
+
+    "text" => "VARCHAR(MAX)"
+    "blob" => "VARBINARY(MAX)"
+
+Additionally `SQLServerPlatform` in DBAL 2.1 and before used "DATE", "TIME" and "DATETIME2" for dates.
+This types are only available since version 2008 and the introduction of an explicit
+SQLServer 2008 platform makes this dependency explicit.
+
+An `SQLServer2005Platform` was also introduced to differentiate the features between
+versions 2003, earlier and 2005.
+
+With this change the `SQLServerPlatform` now throws an exception for using limit queries
+with an offset, since SQLServer 2003 and lower do not support this feature.
+
+To use the old SQL Server Platform, because you are using SQL Server 2003 and below use
+the following configuration code:
+
+    use Doctrine\DBAL\DriverManager;
+    use Doctrine\DBAL\Platforms\SQLServerPlatform;
+    use Doctrine\DBAL\Platforms\SQLServer2005Platform;
+
+    // You are using SQL Server 2003 or earlier
+    $conn = DriverManager::getConnection(array(
+        'driver' => 'pdo_sqlsrv',
+        'platform' => new SQLServerPlatform()
+        // .. additional parameters
+    ));
+
+    // You are using SQL Server 2005
+    $conn = DriverManager::getConnection(array(
+        'driver' => 'pdo_sqlsrv',
+        'platform' => new SQLServer2005Platform()
+        // .. additional parameters
+    ));
+
+    // You are using SQL Server 2008
+    $conn = DriverManager::getConnection(array(
+        'driver' => 'pdo_sqlsrv',
+        // 2008 is default platform
+        // .. additional parameters
+    ));

+/**
+ * Master-Slave Connection
+ *
+ * Connection can be used with master-slave setups.
+ *
+ * Important for the understanding of this connection should be how and when
+ * it picks the slave or master.
+ *
+ * 1. Slave if master was never picked before and ONLY if 'getWrappedConnection'
+ *    or 'executeQuery' is used.
+ * 2. Master picked when 'exec', 'executeUpdate', 'insert', 'delete', 'update', 'createSavepoint',
+ *    'releaseSavepoint', 'beginTransaction', 'rollback', 'commit', 'query' or
+ *    'prepare' is called.
+ * 3. If master was picked once during the lifetime of the connection it will always get picked afterwards.
+ * 4. One slave connection is randomly picked ONCE during a request.
+ *
+ * ATTENTION: You can write to the slave with this connection if you execute a write query without
+ * opening up a transaction. For example:
+ *
+ *      $conn = DriverManager::getConnection(...);
+ *      $conn->executeQuery("DELETE FROM table");
+ *
+ * Be aware that Connection#executeQuery is a method specifically for READ
+ * operations only.
+ *
+ * This connection is limited to slave operations using the
+ * Connection#executeQuery operation only, because it wouldn't be compatible
+ * with the ORM or SchemaManager code otherwise. Both use all the other
+ * operations in a context where writes could happen to a slave, which makes
+ * this restricted approach necessary.
+ *
+ * You can manually connect to the master at any time by calling:
+ *
+ *      $conn->connect('master');
+ *
+ * Instantiation through the DriverManager looks like:
+ *
+ * @example
+ *
+ * $conn = DriverManager::getConnection(array(
+ *    'wrapperClass' => 'Doctrine\DBAL\Connections\MasterSlaveConnection',
+ *    'driver' => 'pdo_mysql',
+ *    'master' => array('user' => '', 'password' => '', 'host' => '', 'dbname' => ''),
+ *    'slaves' => array(
+ *        array('user' => 'slave1', 'password', 'host' => '', 'dbname' => ''),
+ *        array('user' => 'slave2', 'password', 'host' => '', 'dbname' => ''),
+ *    )
+ * ));
+ *
+ * You can also pass 'driverOptions' and any other documented option to each of this drivers to pass additional information.

+/**
+ * Table ID Generator for those poor languages that are missing sequences.
+ *
+ * WARNING: The Table Id Generator clones a second independent database
+ * connection to work correctly. This means using the generator requests that
+ * generate IDs will have two open database connections. This is necessary to
+ * be safe from transaction failures in the main connection. Make sure to only
+ * ever use one TableGenerator otherwise you end up with many connections.
+ *
+ * TableID Generator does not work with SQLite.
+ *
+ * The TableGenerator does not take care of creating the SQL Table itself. You
+ * should look at the `TableGeneratorSchemaVisitor` to do this for you.
+ * Otherwise the schema for a table looks like:
+ *
+ * CREATE sequences (
+ *   sequence_name VARCHAR(255) NOT NULL,
+ *   sequence_value INT NOT NULL DEFAULT '1',
+ *   sequence_increment_by INT NOT NULL DEFAULT '1',
+ *   PRIMARY KEY (table_name)
+ * );
+ *
+ * Technically this generator works as follows:
+ *
+ * 1. Use a robust transaction serialization level.
+ * 2. Open transaction
+ * 3. Acquire a read lock on the table row (SELECT .. FOR UPDATE)
+ * 4. Increment current value by one and write back to database
+ * 5. Commit transaction
+ *
+ * If you are using a sequence_increment_by value that is larger than one the
+ * ID Generator will keep incrementing values until it hits the incrementation
+ * gap before issuing another query.
+ *
+ * If no row is present for a given sequence a new one will be created with the
+ * default values 'value' = 1 and 'increment_by' = 1

+/**
+ * Object representation of a database schema.
+ *
+ * Different vendors have very inconsistent naming with regard to the concept
+ * of a "schema". Doctrine understands a schema as the entity that conceptually
+ * wraps a set of database objects such as tables, sequences, indexes and
+ * foreign keys that belong to each other into a namespace. A Doctrine Schema
+ * has nothing to do with the "SCHEMA" defined as in PostgreSQL, it is more
+ * related to the concept of "DATABASE" that exists in MySQL and PostgreSQL.
+ *
+ * Every asset in the doctrine schema has a name. A name consists of either a
+ * namespace.local name pair or just a local unqualified name.
+ *
+ * The abstraction layer that covers a PostgreSQL schema is the namespace of an
+ * database object (asset). A schema can have a name, which will be used as
+ * default namespace for the unqualified database objects that are created in
+ * the schema.
+ *
+ * In the case of MySQL where cross-database queries are allowed this leads to
+ * databases being "misinterpreted" as namespaces. This is intentional, however
+ * the CREATE/DROP SQL visitors will just filter this queries and do not
+ * execute them. Only the queries for the currently connected database are
+ * executed.

+ * Sharding implementation that pools many different connections
+ * internally and serves data from the currently active connection.
+ *
+ * The internals of this class are:
+ *
+ * - All sharding clients are specified and given a shard-id during
+ *   configuration.
+ * - By default, the global shard is selected. If no global shard is configured
+ *   an exception is thrown on access.
+ * - Selecting a shard by distribution value delegates the mapping
+ *   "distributionValue" => "client" to the ShardChooser interface.
+ * - An exception is thrown if trying to switch shards during an open
+ *   transaction.
+ *
+ * Instantiation through the DriverManager looks like:
+ *
+ * @example
+ *
+ * $conn = DriverManager::getConnection(array(
+ *    'wrapperClass' => 'Doctrine\DBAL\Sharding\PoolingShardConnection',

+ *   global or federated database is undefined. It depends on you selecting a

+ * - Every Primary key of a federated table is extended by another column
+ *   'tenant_id' with a default value of the SQLAzure function
+ *   `federation_filtering_value('tenant_id')`.
+ * - You always have to work with `filtering=On` when using federations with this
+ *   multi-tenant approach.
+ * - Primary keys are either using globally unique ids (GUID, Table Generator)
+ *   or you explicitly add the tenent_id in every UPDATE or DELETE statement
+ *   (otherwise they will affect the same-id rows from other tenents as well).

+ * attached to a DateTime instance (for example "Europe/Berlin" or "America/Montreal")
+ * but the current offset of them related to UTC. That means depending on daylight saving times

+ *
+ * This datatype makes only sense to use, if your application works with an offset, not
+ * with an actual timezone that uses transitions. Otherwise your DateTime instance
+ * attached with a timezone such as Europe/Berlin gets saved into the database with
+ * the offset and re-created from persistence with only the offset, not the original timezone

+PHP-JWT
+=======
+A simple library to encode and decode JSON Web Tokens (JWT) in PHP, conforming to [RFC 7519](https://tools.ietf.org/html/rfc7519).
+
+Installation
+------------
+
+Use composer to manage your dependencies and download PHP-JWT:
+
+```bash
+composer require firebase/php-jwt
+```
+
+Example
+-------
+```php
+<?php
+use \Firebase\JWT\JWT;
+
+$key = "example_key";
+$token = array(
+    "iss" => "http://example.org",
+    "aud" => "http://example.com",
+    "iat" => 1356999524,
+    "nbf" => 1357000000
+);
+
+/**
+ * IMPORTANT:
+ * You must specify supported algorithms for your application. See
+ * https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
+ * for a list of spec-compliant algorithms.
+ */
+$jwt = JWT::encode($token, $key);
+$decoded = JWT::decode($jwt, $key, array('HS256'));
+
+print_r($decoded);
+
+/*
+ NOTE: This will now be an object instead of an associative array. To get
+ an associative array, you will need to cast it as such:
+*/
+
+$decoded_array = (array) $decoded;
+
+/**
+ * You can add a leeway to account for when there is a clock skew times between
+ * the signing and verifying servers. It is recommended that this leeway should
+ * not be bigger than a few minutes.
+ *
+ * Source: http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#nbfDef
+ */

+- Update signature for `JWT::decode(...)` to require an array of supported
+  algorithms to use when verifying token signatures.
+
+
+Tests
+-----
+Run the tests using phpunit:
+
+```bash
+$ pear install PHPUnit
+$ phpunit --configuration phpunit.xml.dist
+PHPUnit 3.7.10 by Sebastian Bergmann.
+.....
+Time: 0 seconds, Memory: 2.50Mb
+OK (5 tests, 5 assertions)
+```
+
+New Lines in private keys
+-----
+
+If your private key contains `\n` characters, be sure to wrap it in double quotes `""`
+and not single quotes `''` in order to properly interpret the escaped characters.

+Pimple
+======
+
+.. caution::
+
+    This is the documentation for Pimple 3.x. If you are using Pimple 1.x, read
+    the `Pimple 1.x documentation`_. Reading the Pimple 1.x code is also a good
+    way to learn more about how to create a simple Dependency Injection
+    Container (recent versions of Pimple are more focused on performance).
+
+Pimple is a small Dependency Injection Container for PHP.
+
+Installation
+------------
+
+Before using Pimple in your project, add it to your ``composer.json`` file:
+
+.. code-block:: bash
+
+    $ ./composer.phar require pimple/pimple ~3.0
+
+Alternatively, Pimple is also available as a PHP C extension:
+
+.. code-block:: bash
+
+    $ git clone https://github.com/silexphp/Pimple
+    $ cd Pimple/ext/pimple
+    $ phpize
+    $ ./configure
+    $ make
+    $ make install
+
+Usage
+-----
+
+Creating a container is a matter of creating a ``Container`` instance:
+
+.. code-block:: php
+
+    use Pimple\Container;
+
+    $container = new Container();
+
+As many other dependency injection containers, Pimple manages two different
+kind of data: **services** and **parameters**.
+
+Defining Services
+~~~~~~~~~~~~~~~~~
+
+A service is an object that does something as part of a larger system. Examples
+of services: a database connection, a templating engine, or a mailer. Almost
+any **global** object can be a service.
+
+Services are defined by **anonymous functions** that return an instance of an
+object:
+
+.. code-block:: php
+
+    // define some services
+    $container['session_storage'] = function ($c) {
+        return new SessionStorage('SESSION_ID');
+    };
+
+    $container['session'] = function ($c) {
+        return new Session($c['session_storage']);
+    };
+
+Notice that the anonymous function has access to the current container
+instance, allowing references to other services or parameters.
+
+As objects are only created when you get them, the order of the definitions
+does not matter.
+
+Using the defined services is also very easy:
+
+.. code-block:: php
+
+    // get the session object
+    $session = $container['session'];
+
+    // the above call is roughly equivalent to the following code:
+    // $storage = new SessionStorage('SESSION_ID');
+    // $session = new Session($storage);
+
+Defining Factory Services
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, each time you get a service, Pimple returns the **same instance**
+of it. If you want a different instance to be returned for all calls, wrap your
+anonymous function with the ``factory()`` method
+
+.. code-block:: php
+
+    $container['session'] = $container->factory(function ($c) {
+        return new Session($c['session_storage']);
+    });
+
+Now, each call to ``$container['session']`` returns a new instance of the
+session.
+
+Defining Parameters
+~~~~~~~~~~~~~~~~~~~
+
+Defining a parameter allows to ease the configuration of your container from
+the outside and to store global values:
+
+.. code-block:: php
+
+    // define some parameters
+    $container['cookie_name'] = 'SESSION_ID';
+    $container['session_storage_class'] = 'SessionStorage';
+
+If you change the ``session_storage`` service definition like below:
+
+.. code-block:: php
+
+    $container['session_storage'] = function ($c) {
+        return new $c['session_storage_class']($c['cookie_name']);
+    };
+
+You can now easily change the cookie name by overriding the
+``session_storage_class`` parameter instead of redefining the service
+definition.
+
+Protecting Parameters
+~~~~~~~~~~~~~~~~~~~~~
+
+Because Pimple sees anonymous functions as service definitions, you need to
+wrap anonymous functions with the ``protect()`` method to store them as
+parameters:
+
+.. code-block:: php
+
+    $container['random_func'] = $container->protect(function () {
+        return rand();
+    });
+
+Modifying Services after Definition
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In some cases you may want to modify a service definition after it has been
+defined. You can use the ``extend()`` method to define additional code to be
+run on your service just after it is created:
+
+.. code-block:: php
+
+    $container['session_storage'] = function ($c) {
+        return new $c['session_storage_class']($c['cookie_name']);
+    };
+
+    $container->extend('session_storage', function ($storage, $c) {
+        $storage->...();
+
+        return $storage;
+    });
+
+The first argument is the name of the service to extend, the second a function
+that gets access to the object instance and the container.
+
+Extending a Container
+~~~~~~~~~~~~~~~~~~~~~
+
+If you use the same libraries over and over, you might want to reuse some
+services from one project to the next one; package your services into a
+**provider** by implementing ``Pimple\ServiceProviderInterface``:
+
+.. code-block:: php
+
+    use Pimple\Container;
+
+    class FooProvider implements Pimple\ServiceProviderInterface
+    {
+        public function register(Container $pimple)
+        {
+            // register some services and parameters
+            // on $pimple
+        }
+    }
+
+Then, register the provider on a Container:
+
+.. code-block:: php
+
+    $pimple->register(new FooProvider());
+
+Fetching the Service Creation Function
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When you access an object, Pimple automatically calls the anonymous function
+that you defined, which creates the service object for you. If you want to get
+raw access to this function, you can use the ``raw()`` method:
+
+.. code-block:: php
+
+    $container['session'] = function ($c) {
+        return new Session($c['session_storage']);
+    };
+
+    $sessionFunction = $container->raw('session');

+PSR Log
+=======
+
+This repository holds all interfaces/classes/traits related to
+[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
+
+Note that this is not a logger of its own. It is merely an interface that
+describes a logger. See the specification for more details.
+
+Usage
+-----
+
+If you need a logger, you can use the interface like this:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+
+class Foo
+{
+    private $logger;
+
+    public function __construct(LoggerInterface $logger = null)
+    {
+        $this->logger = $logger;
+    }
+
+    public function doSomething()
+    {
+        if ($this->logger) {
+            $this->logger->info('Doing work');
+        }
+
+        // do something useful
+    }
+}
+```
+
+You can then pick one of the implementations of the interface to get a logger.
+
+If you want to implement the interface, you can require this package and
+implement `Psr\Log\LoggerInterface` in your code. Please read the
+[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+for details.

+Silex, a simple Web Framework
+=============================
+
+Silex is a PHP micro-framework to develop websites based on `Symfony
+components`_::
+
+    <?php
+
+    require_once __DIR__.'/../vendor/autoload.php';
+
+    $app = new Silex\Application();
+
+    $app->get('/hello/{name}', function ($name) use ($app) {
+      return 'Hello '.$app->escape($name);
+    });
+
+    $app->run();
+
+Silex works with PHP 5.5.9 or later.

+      })->host('example.com');
+
+      $app->match('/', function ($user) {
+          // user-specific action
+      })->host('{user}.example.com');
+
+* **2013-03-08**: Added support for form type extensions and guessers as

+  ``BinaryFileResponse``.
+
+* **2012-11-05**: Filters have been renamed to application middlewares in the
+  documentation.
+
+* **2012-11-05**: The ``before()``, ``after()``, ``error()``, and ``finish()``
+  listener priorities now set the priority of the underlying Symfony event
+  instead of a custom one before.
+
+* **2012-11-05**: Removing the default exception handler should now be done
+  via its ``disable()`` method:
+
+    Before:
+
+        unset($app['exception_handler']);
+
+    After:
+
+        $app['exception_handler']->disable();
+
+* **2012-07-15**: removed the ``monolog.configure`` service. Use the
+  ``extend`` method instead:
+
+    Before::
+
+        $app['monolog.configure'] = $app->protect(function ($monolog) use ($app) {
+            // do something
+        });
+
+    After::
+
+        $app['monolog'] = $app->share($app->extend('monolog', function($monolog, $app) {
+            // do something
+
+            return $monolog;
+        }));

+
+* **2012-06-17**: ``ControllerCollection`` now takes a required route instance
+  as a constructor argument.
+
+    Before::

+        $controllers = new ControllerCollection();
+
+    After::
+
+        $controllers = new ControllerCollection(new Route());
+
+        // or even better
+        $controllers = $app['controllers_factory'];
+
+* **2012-06-17**: added application traits for PHP 5.4
+
+* **2012-06-16**: renamed ``request.default_locale`` to ``locale``
+
+* **2012-06-16**: Removed the ``translator.loader`` service. See documentation
+  for how to use XLIFF or YAML-based translation files.
+
+* **2012-06-15**: removed the ``twig.configure`` service. Use the ``extend``
+  method instead:
+
+    Before::
+
+        $app['twig.configure'] = $app->protect(function ($twig) use ($app) {
+            // do something
+        });
+
+    After::
+
+        $app['twig'] = $app->share($app->extend('twig', function($twig, $app) {
+            // do something

+            return $twig;
+        }));

+
+* **2012-06-13**: Renamed the route ``middleware`` to ``before``

+
+* **2012-05-31**: Made the ``BrowserKit``, ``CssSelector``, ``DomCrawler``,
+  ``Finder`` and ``Process`` components optional dependencies. Projects that
+  depend on them (e.g. through functional tests) should add those dependencies
+  to their ``composer.json``.
+
+* **2012-05-26**: added ``boot()`` to ``ServiceProviderInterface``.
+
+* **2012-05-26**: Removed ``SymfonyBridgesServiceProvider``. It is now implicit
+  by checking the existence of the bridge.
+
+* **2012-05-26**: Removed the ``translator.messages`` parameter (use
+  ``translator.domains`` instead).
+
+* **2012-05-24**: Removed the ``autoloader`` service (use composer instead).
+  The ``*.class_path`` settings on all the built-in providers have also been
+  removed in favor of Composer.
+
+* **2012-05-21**: Changed error() to allow handling specific exceptions.
+
+* **2012-05-20**: Added a way to define settings on a controller collection.
+
+* **2012-05-20**: The Request instance is not available anymore from the
+  Application after it has been handled.
+
+* **2012-04-01**: Added ``finish`` filters.
+
+* **2012-03-20**: Added ``json`` helper::
+
+        $data = array('some' => 'data');
+        $response = $app->json($data);
+
+* **2012-03-11**: Added route middlewares.
+
+* **2012-03-02**: Switched to use Composer for dependency management.
+
+* **2012-02-27**: Updated to Symfony 2.1 session handling.
+
+* **2012-01-02**: Introduced support for streaming responses.
+
+* **2011-09-22**: ``ExtensionInterface`` has been renamed to

+Converting Errors to Exceptions
+===============================
+
+Silex catches exceptions that are thrown from within a request/response cycle.
+However, it does *not* catch PHP errors and notices. This recipe tells you how
+to catch them by converting them to exceptions.
+
+Registering the ErrorHandler
+----------------------------
+
+The ``Symfony/Debug`` package has an ``ErrorHandler`` class that solves this
+problem. It converts all errors to exceptions, and exceptions are then caught
+by Silex.
+
+Register it by calling the static ``register`` method::
+
+    use Symfony\Component\Debug\ErrorHandler;
+
+    ErrorHandler::register();
+
+It is recommended that you do this as early as possible.
+
+Handling fatal errors
+---------------------
+
+To handle fatal errors, you can additionally register a global
+``ExceptionHandler``::
+
+    use Symfony\Component\Debug\ExceptionHandler;
+
+    ExceptionHandler::register();
+
+In production you may want to disable the debug output by passing ``false`` as
+the ``$debug`` argument::
+
+    use Symfony\Component\Debug\ExceptionHandler;
+
+    ExceptionHandler::register(false);

+Disabling CSRF Protection on a Form using the FormExtension
+===========================================================
+
+The *FormExtension* provides a service for building form in your application
+with the Symfony Form component. When the :doc:`CSRF Service Provider
+</providers/csrf>` is registered, the *FormExtension* uses the CSRF Protection
+avoiding Cross-site request forgery, a method by which a malicious user
+attempts to make your legitimate users unknowingly submit data that they don't
+intend to submit.
+
+You can find more details about CSRF Protection and CSRF token in the
+`Symfony Book
+<http://symfony.com/doc/current/book/forms.html#csrf-protection>`_.
+
+In some cases (for example, when embedding a form in an html email) you might
+want not to use this protection. The easiest way to avoid this is to
+understand that it is possible to give specific options to your form builder
+through the ``createBuilder()`` function.
+
+Example
+-------
+
+.. code-block:: php
+
+    $form = $app['form.factory']->createBuilder('form', null, array('csrf_protection' => false));
+
+That's it, your form could be submitted from everywhere without CSRF Protection.
+
+Going further
+-------------
+
+This specific example showed how to change the ``csrf_protection`` in the
+``$options`` parameter of the ``createBuilder()`` function. More of them could
+be passed through this parameter, it is as simple as using the Symfony
+``getDefaultOptions()`` method in your form classes. `See more here
+<http://symfony.com/doc/current/book/forms.html#book-form-creating-form-classes>`_.

+How to Create a Custom Authentication System with Guard
+=======================================================
+
+Whether you need to build a traditional login form, an API token
+authentication system or you need to integrate with some proprietary
+single-sign-on system, the Guard component can make it easy... and fun!
+
+In this example, you'll build an API token authentication system and
+learn how to work with Guard.
+
+Step 1) Create the Authenticator Class
+--------------------------------------
+
+Suppose you have an API where your clients will send an X-AUTH-TOKEN
+header on each request. This token is composed of the username followed
+by a password, separated by a colon (e.g. ``X-AUTH-TOKEN: coolguy:awesomepassword``).
+Your job is to read this, find the associated user (if any) and check
+the password.
+
+To create a custom authentication system, just create a class and make
+it implement GuardAuthenticatorInterface. Or, extend the simpler
+AbstractGuardAuthenticator. This requires you to implement six methods:
+
+.. code-block:: php
+
+    <?php
+
+    namespace App\Security;
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpFoundation\JsonResponse;
+    use Symfony\Component\Security\Core\User\UserInterface;
+    use Symfony\Component\Security\Core\User\UserProviderInterface;
+    use Symfony\Component\Security\Guard\AbstractGuardAuthenticator;
+    use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
+    use Symfony\Component\Security\Core\Exception\AuthenticationException;
+
+    class TokenAuthenticator extends AbstractGuardAuthenticator
+    {
+        private $encoderFactory;
+
+        public function __construct(EncoderFactoryInterface $encoderFactory)
+        {
+            $this->encoderFactory = $encoderFactory;
+        }
+
+        public function getCredentials(Request $request)
+        {
+            // Checks if the credential header is provided
+            if (!$token = $request->headers->get('X-AUTH-TOKEN')) {
+                return;
+            }
+
+            // Parse the header or ignore it if the format is incorrect.
+            if (false === strpos($token, ':')) {
+                return;
+            }
+            list($username, $secret) = explode(':', $token, 2);
+
+            return array(
+                'username' => $username,
+                'secret' => $secret,
+            );
+        }
+
+        public function getUser($credentials, UserProviderInterface $userProvider)
+        {
+            return $userProvider->loadUserByUsername($credentials['username']);
+        }
+
+        public function checkCredentials($credentials, UserInterface $user)
+        {
+            // check credentials - e.g. make sure the password is valid
+            // return true to cause authentication success
+
+            $encoder = $this->encoderFactory->getEncoder($user);
+
+            return $encoder->isPasswordValid(
+                $user->getPassword(),
+                $credentials['secret'],
+                $user->getSalt()
+            );
+        }
+
+        public function onAuthenticationSuccess(Request $request, TokenInterface $token, $providerKey)
+        {
+            // on success, let the request continue
+            return;
+        }
+
+        public function onAuthenticationFailure(Request $request, AuthenticationException $exception)
+        {
+            $data = array(
+                'message' => strtr($exception->getMessageKey(), $exception->getMessageData()),
+
+                // or to translate this message
+                // $this->translator->trans($exception->getMessageKey(), $exception->getMessageData())
+            );
+
+            return new JsonResponse($data, 403);
+        }
+
+        /**
+         * Called when authentication is needed, but it's not sent
+         */
+        public function start(Request $request, AuthenticationException $authException = null)
+        {
+            $data = array(
+                // you might translate this message
+                'message' => 'Authentication Required',
+            );
+
+            return new JsonResponse($data, 401);
+        }
+
+        public function supportsRememberMe()
+        {
+            return false;
+        }
+    }
+
+
+Step 2) Configure the Authenticator
+-----------------------------------
+
+To finish this, register the class as a service:
+
+.. code-block:: php
+
+    $app['app.token_authenticator'] = function ($app) {
+        return new App\Security\TokenAuthenticator($app['security.encoder_factory']);
+    };
+
+
+Finally, configure your `security.firewalls` key to use this authenticator:
+
+.. code-block:: php
+
+    $app['security.firewalls'] => array(
+        'main' => array(
+            'guard' => array(
+                'authenticators' => array(
+                    'app.token_authenticator'
+                ),
+
+                // Using more than 1 authenticator, you must specify
+                // which one is used as entry point.
+                // 'entry_point' => 'app.token_authenticator',
+            ),
+            // configure where your users come from. Hardcode them, or load them from somewhere
+            // http://silex.sensiolabs.org/doc/providers/security.html#defining-a-custom-user-provider
+            'users' => array(
+                'victoria' => array('ROLE_USER', 'randomsecret'),
+            ),
+            // 'anonymous' => true
+        ),
+    );
+
+.. note::
+    You can use many authenticators, they are executed by the order
+    they are configured.
+
+You did it! You now have a fully-working API token authentication
+system. If your homepage required ROLE_USER, then you could test it
+under different conditions:
+
+.. code-block:: bash
+
+    # test with no token
+    curl http://localhost:8000/
+    # {"message":"Authentication Required"}
+
+    # test with a bad token
+    curl -H "X-AUTH-TOKEN: alan" http://localhost:8000/
+    # {"message":"Username could not be found."}
+
+    # test with a working token
+    curl -H "X-AUTH-TOKEN: victoria:randomsecret" http://localhost:8000/
+    # the homepage controller is executed: the page loads normally

+`How to Create a Custom Authentication System with Guard <http://symfony.com/doc/current/cookbook/security/guard-authentication.html>`_.

+Accepting a JSON Request Body
+=============================
+
+A common need when building a restful API is the ability to accept a JSON
+encoded entity from the request body.
+
+An example for such an API could be a blog post creation.
+
+Example API
+-----------
+
+In this example we will create an API for creating a blog post. The following
+is a spec of how we want it to work.
+
+Request
+~~~~~~~
+
+In the request we send the data for the blog post as a JSON object. We also
+indicate that using the ``Content-Type`` header:
+
+.. code-block:: text
+
+    POST /blog/posts
+    Accept: application/json
+    Content-Type: application/json
+    Content-Length: 57
+
+    {"title":"Hello World!","body":"This is my first post!"}
+
+Response
+~~~~~~~~
+
+The server responds with a 201 status code, telling us that the post was
+created. It tells us the ``Content-Type`` of the response, which is also
+JSON:
+
+.. code-block:: text
+
+    HTTP/1.1 201 Created
+    Content-Type: application/json
+    Content-Length: 65
+    Connection: close
+
+    {"id":"1","title":"Hello World!","body":"This is my first post!"}
+
+Parsing the request body
+------------------------
+
+The request body should only be parsed as JSON if the ``Content-Type`` header
+begins with ``application/json``. Since we want to do this for every request,
+the easiest solution is to use an application before middleware.
+
+We simply use ``json_decode`` to parse the content of the request and then
+replace the request data on the ``$request`` object::
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpFoundation\ParameterBag;
+
+    $app->before(function (Request $request) {
+        if (0 === strpos($request->headers->get('Content-Type'), 'application/json')) {
+            $data = json_decode($request->getContent(), true);
+            $request->request->replace(is_array($data) ? $data : array());
+        }
+    });
+
+Controller implementation
+-------------------------
+
+Our controller will create a new blog post from the data provided and will
+return the post object, including its ``id``, as JSON::
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpFoundation\Response;
+
+    $app->post('/blog/posts', function (Request $request) use ($app) {
+        $post = array(
+            'title' => $request->request->get('title'),
+            'body'  => $request->request->get('body'),
+        );
+
+        $post['id'] = createPost($post);
+
+        return $app->json($post, 201);
+    });
+
+Manual testing
+--------------
+
+In order to manually test our API, we can use the ``curl`` command line
+utility, which allows sending HTTP requests:
+
+.. code-block:: bash
+
+    $ curl http://blog.lo/blog/posts -d '{"title":"Hello World!","body":"This is my first post!"}' -H 'Content-Type: application/json'
+    {"id":"1","title":"Hello World!","body":"This is my first post!"}

+Using multiple Monolog Loggers
+==============================
+
+Having separate instances of Monolog for different parts of your system is
+often desirable and allows you to configure them independently, allowing for fine
+grained control of where your logging goes and in what detail.
+
+This simple example allows you to quickly configure several monolog instances,
+using the bundled handler, but each with a different channel. 
+
+.. code-block:: php
+
+    $app['monolog.factory'] = $app->protect(function ($name) use ($app) {
+        $log = new $app['monolog.logger.class']($name);
+        $log->pushHandler($app['monolog.handler']);
+
+        return $log;
+    });
+
+    foreach (array('auth', 'payments', 'stats') as $channel) {
+        $app['monolog.'.$channel] = function ($app) use ($channel) {
+            return $app['monolog.factory']($channel);
+        };
+    }
+
+As your application grows, or your logging needs for certain areas of the
+system become apparent, it should be straightforward to then configure that
+particular service separately, including your customizations.
+
+.. code-block:: php
+
+    use Monolog\Handler\StreamHandler;
+
+    $app['monolog.payments'] = function ($app) {
+        $log = new $app['monolog.logger.class']('payments');
+        $handler = new StreamHandler($app['monolog.payments.logfile'], $app['monolog.payment.level']);
+        $log->pushHandler($handler);
+
+        return $log;
+    };
+
+Alternatively, you could attempt to make the factory more complicated, and rely
+on some conventions, such as checking for an array of handlers registered with
+the container with the channel name, defaulting to the bundled handler.
+
+.. code-block:: php
+
+    use Monolog\Handler\StreamHandler;
+    use Monolog\Logger;
+
+    $app['monolog.factory'] = $app->protect(function ($name) use ($app) {
+        $log = new $app['monolog.logger.class']($name);
+
+        $handlers = isset($app['monolog.'.$name.'.handlers'])
+            ? $app['monolog.'.$name.'.handlers']
+            : array($app['monolog.handler']);
+
+        foreach ($handlers as $handler) {
+            $log->pushHandler($handler);
+        }
+
+        return $log;
+    });
+
+    $app['monolog.payments.handlers'] = function ($app) {
+        return array(
+            new StreamHandler(__DIR__.'/../payments.log', Logger::DEBUG),
+        );

+Using PdoSessionStorage to store Sessions in the Database
+=========================================================
+
+By default, the :doc:`SessionServiceProvider </providers/session>` writes
+session information in files using Symfony NativeFileSessionStorage. Most
+medium to large websites use a database to store sessions instead of files,
+because databases are easier to use and scale in a multi-webserver environment.
+
+Symfony's `NativeSessionStorage
+<http://api.symfony.com/master/Symfony/Component/HttpFoundation/Session/Storage/NativeSessionStorage.html>`_
+has multiple storage handlers and one of them uses PDO to store sessions,
+`PdoSessionHandler
+<http://api.symfony.com/master/Symfony/Component/HttpFoundation/Session/Storage/Handler/PdoSessionHandler.html>`_.

+            $app['session.storage.options']
+        );
+    };
+
+Using the DoctrineServiceProvider
+---------------------------------
+
+When using the :doc:`DoctrineServiceProvider </providers/doctrine>` You don't
+have to make another database connection, simply pass the getWrappedConnection method.
+
+.. code-block:: php
+
+    use Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler;
+
+    $app->register(new Silex\Provider\SessionServiceProvider());
+
+    $app['session.db_options'] = array(
+        'db_table'        => 'session',
+        'db_id_col'       => 'session_id',
+        'db_data_col'     => 'session_value',
+        'db_lifetime_col' => 'session_lifetime',
+        'db_time_col'     => 'session_time',
+    );
+
+    $app['session.storage.handler'] = function () use ($app) {
+        return new PdoSessionHandler(
+            $app['db']->getWrappedConnection(),
+            $app['session.db_options'],
+            $app['session.storage.options']
+        );
+    };
+
+Database structure
+------------------
+
+PdoSessionStorage needs a database table with 3 columns:
+
+* ``session_id``: ID column (VARCHAR(255) or larger)
+* ``session_value``: Value column (TEXT or CLOB)
+* ``session_lifetime``: Lifetime column (INTEGER)
+* ``session_time``: Time column (INTEGER)
+
+You can find examples of SQL statements to create the session table in the
+`Symfony cookbook
+<http://symfony.com/doc/current/cookbook/configuration/pdo_session_storage.html#example-sql-statements>`_

+Making sub-Requests
+===================
+
+Since Silex is based on the ``HttpKernelInterface``, it allows you to simulate
+requests against your application. This means that you can embed a page within
+another, it also allows you to forward a request which is essentially an
+internal redirect that does not change the URL.
+
+Basics
+------
+
+You can make a sub-request by calling the ``handle`` method on the
+``Application``. This method takes three arguments:
+
+* ``$request``: An instance of the ``Request`` class which represents the
+   HTTP request.
+
+* ``$type``: Must be either ``HttpKernelInterface::MASTER_REQUEST`` or
+  ``HttpKernelInterface::SUB_REQUEST``. Certain listeners are only executed for
+  the master request, so it's important that this is set to ``SUB_REQUEST``.
+
+* ``$catch``: Catches exceptions and turns them into a response with status code
+  ``500``. This argument defaults to ``true``. For sub-requests you will most
+  likely want to set it to ``false``.
+
+By calling ``handle``, you can make a sub-request manually. Here's an example::
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpKernel\HttpKernelInterface;
+
+    $subRequest = Request::create('/');
+    $response = $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);
+
+There's some more things that you need to keep in mind though. In most cases
+you will want to forward some parts of the current master request to the
+sub-request like cookies, server information, or the session.
+
+Here is a more advanced example that forwards said information (``$request``
+holds the master request)::
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpKernel\HttpKernelInterface;
+
+    $subRequest = Request::create('/', 'GET', array(), $request->cookies->all(), array(), $request->server->all());
+    if ($request->getSession()) {
+        $subRequest->setSession($request->getSession());
+    }
+
+    $response = $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);
+
+To forward this response to the client, you can simply return it from a
+controller::
+
+    use Silex\Application;
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpKernel\HttpKernelInterface;
+
+    $app->get('/foo', function (Application $app, Request $request) {
+        $subRequest = Request::create('/', ...);
+        $response = $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);
+
+        return $response;
+    });
+
+If you want to embed the response as part of a larger page you can call
+``Response::getContent``::
+
+    $header = ...;
+    $footer = ...;
+    $body = $response->getContent();
+
+    return $header.$body.$footer;
+
+Rendering pages in Twig templates
+---------------------------------
+
+The :doc:`TwigServiceProvider </providers/twig>` provides a ``render``
+function that you can use in Twig templates. It gives you a convenient way to
+embed pages.
+
+.. code-block:: jinja
+
+    {{ render('/sidebar') }}
+
+For details, refer to the :doc:`TwigServiceProvider </providers/twig>` docs.
+
+Edge Side Includes
+------------------
+
+You can use ESI either through the :doc:`HttpCacheServiceProvider
+</providers/http_cache>` or a reverse proxy cache such as Varnish. This also
+allows you to embed pages, however it also gives you the benefit of caching
+parts of the page.
+
+Here is an example of how you would embed a page via ESI:
+
+.. code-block:: jinja
+
+    <esi:include src="/sidebar" />
+
+For details, refer to the :doc:`HttpCacheServiceProvider
+</providers/http_cache>` docs.
+
+Dealing with the request base URL
+---------------------------------
+
+One thing to watch out for is the base URL. If your application is not
+hosted at the webroot of your web server, then you may have an URL like
+``http://example.org/foo/index.php/articles/42``.
+
+In this case, ``/foo/index.php`` is your request base path. Silex accounts for
+this path prefix in the routing process, it reads it from
+``$request->server``. In the context of sub-requests this can lead to issues,
+because if you do not prepend the base path the request could mistake a part
+of the path you want to match as the base path and cut it off.
+
+You can prevent that from happening by always prepending the base path when
+constructing a request::
+
+    $url = $request->getUriForPath('/');
+    $subRequest = Request::create($url, 'GET', array(), $request->cookies->all(), array(), $request->server->all());
+
+This is something to be aware of when making sub-requests by hand.
+
+Services depending on the Request
+---------------------------------
+
+The container is a concept that is global to a Silex application, since the
+application object **is** the container. Any request that is run against an
+application will re-use the same set of services. Since these services are
+mutable, code in a master request can affect the sub-requests and vice versa.
+Any services depending on the ``request`` service will store the first request
+that they get (could be master or sub-request), and keep using it, even if
+that request is already over.
+
+Instead of injecting the ``request`` service, you should always inject the
+``request_stack`` one instead.

+Using YAML to configure Validation
+==================================
+
+Simplicity is at the heart of Silex so there is no out of the box solution to
+use YAML files for validation. But this doesn't mean that this is not
+possible. Let's see how to do it.
+
+First, you need to install the YAML Component:
+
+.. code-block:: bash
+
+    composer require symfony/yaml
+
+Next, you need to tell the Validation Service that you are not using
+``StaticMethodLoader`` to load your class metadata but a YAML file::
+
+    $app->register(new ValidatorServiceProvider());
+
+    $app['validator.mapping.class_metadata_factory'] = new Symfony\Component\Validator\Mapping\ClassMetadataFactory(
+        new Symfony\Component\Validator\Mapping\Loader\YamlFileLoader(__DIR__.'/validation.yml')
+    );
+
+Now, we can replace the usage of the static method and move all the validation
+rules to ``validation.yml``:
+
+.. code-block:: yaml
+
+    # validation.yml
+    Post:
+      properties:
+        title:
+          - NotNull: ~
+          - NotBlank: ~
+        body:
+          - Min: 100

+Internals
+=========
+
+This chapter will tell you how Silex works internally.
+
+Silex
+-----
+
+Application
+~~~~~~~~~~~
+
+The application is the main interface to Silex. It implements Symfony's
+`HttpKernelInterface
+<http://api.symfony.com/master/Symfony/Component/HttpKernel/HttpKernelInterface.html>`_,
+so you can pass a `Request
+<http://api.symfony.com/master/Symfony/Component/HttpFoundation/Request.html>`_
+to the ``handle`` method and it will return a `Response
+<http://api.symfony.com/master/Symfony/Component/HttpFoundation/Response.html>`_.
+
+It extends the ``Pimple`` service container, allowing for flexibility on the
+outside as well as the inside. You could replace any service, and you are also
+able to read them.
+
+The application makes strong use of the `EventDispatcher
+<http://api.symfony.com/master/Symfony/Component/EventDispatcher/EventDispatcher
+.html>`_ to hook into the Symfony `HttpKernel
+<http://api.symfony.com/master/Symfony/Component/HttpKernel/HttpKernel.html>`_
+events. This allows fetching the ``Request``, converting string responses into
+``Response`` objects and handling Exceptions. We also use it to dispatch some
+custom events like before/after middlewares and errors.
+
+Controller
+~~~~~~~~~~
+
+The Symfony `Route
+<http://api.symfony.com/master/Symfony/Component/Routing/Route.html>`_ is
+actually quite powerful. Routes can be named, which allows for URL generation.
+They can also have requirements for the variable parts. In order to allow
+setting these through a nice interface, the ``match`` method (which is used by
+``get``, ``post``, etc.) returns an instance of the ``Controller``, which
+wraps a route.
+
+ControllerCollection
+~~~~~~~~~~~~~~~~~~~~
+
+One of the goals of exposing the `RouteCollection
+<http://api.symfony.com/master/Symfony/Component/Routing/RouteCollection.html>`_
+was to make it mutable, so providers could add stuff to it. The challenge here
+is the fact that routes know nothing about their name. The name only has
+meaning in context of the ``RouteCollection`` and cannot be changed.
+
+To solve this challenge we came up with a staging area for routes. The
+``ControllerCollection`` holds the controllers until ``flush`` is called, at
+which point the routes are added to the ``RouteCollection``. Also, the
+controllers are then frozen. This means that they can no longer be modified
+and will throw an Exception if you try to do so.
+
+Unfortunately no good way for flushing implicitly could be found, which is why
+flushing is now always explicit. The Application will flush, but if you want
+to read the ``ControllerCollection`` before the request takes place, you will
+have to call flush yourself.
+
+The ``Application`` provides a shortcut ``flush`` method for flushing the
+``ControllerCollection``.
+
+.. tip::
+
+    Instead of creating an instance of ``RouteCollection`` yourself, use the
+    ``$app['controllers_factory']`` factory instead.
+
+Symfony
+-------
+
+Following Symfony components are used by Silex:
+
+* **HttpFoundation**: For ``Request`` and ``Response``.
+
+* **HttpKernel**: Because we need a heart.
+
+* **Routing**: For matching defined routes.
+
+* **EventDispatcher**: For hooking into the HttpKernel.
+
+For more information, `check out the Symfony website <http://symfony.com/>`_.

+Introduction
+============
+
+Silex is a PHP microframework. It is built on the shoulders of `Symfony`_ and
+`Pimple`_ and also inspired by `Sinatra`_.
+
+Silex aims to be:
+
+* *Concise*: Silex exposes an intuitive and concise API.
+
+* *Extensible*: Silex has an extension system based around the Pimple
+  service-container that makes it easy to tie in third party libraries.
+
+* *Testable*: Silex uses Symfony's HttpKernel which abstracts request and
+  response. This makes it very easy to test apps and the framework itself. It
+  also respects the HTTP specification and encourages its proper use.
+
+In a nutshell, you define controllers and map them to routes, all in one step.
+
+Usage
+-----
+
+.. code-block:: php
+
+    <?php
+
+    // web/index.php
+    require_once __DIR__.'/../vendor/autoload.php';
+
+    $app = new Silex\Application();
+
+    $app->get('/hello/{name}', function ($name) use ($app) {
+        return 'Hello '.$app->escape($name);
+    });
+
+    $app->run();
+
+All that is needed to get access to the Framework is to include the
+autoloader.
+
+Next, a route for ``/hello/{name}`` that matches for ``GET`` requests is
+defined. When the route matches, the function is executed and the return value
+is sent back to the client.
+
+Finally, the app is run. Visit ``/hello/world`` to see the result. It's really
+that easy!

+Middleware
+==========
+
+Silex allows you to run code, that changes the default Silex behavior, at
+different stages during the handling of a request through *middleware*:
+
+* *Application middleware* is triggered independently of the current handled
+  request;
+
+* *Route middleware* is triggered when its associated route is matched.
+
+Application Middleware
+----------------------
+
+Application middleware is only run for the "master" Request.
+
+Before Middleware
+~~~~~~~~~~~~~~~~~
+
+A *before* application middleware allows you to tweak the Request before the
+controller is executed::
+
+    $app->before(function (Request $request, Application $app) {
+        // ...
+    });
+
+By default, the middleware is run after the routing and the security.
+
+If you want your middleware to be run even if an exception is thrown early on
+(on a 404 or 403 error for instance), then, you need to register it as an
+early event::
+
+    $app->before(function (Request $request, Application $app) {
+        // ...
+    }, Application::EARLY_EVENT);
+
+In this case, the routing and the security won't have been executed, and so you
+won't have access to the locale, the current route, or the security user.
+
+.. note::
+
+    The before middleware is an event registered on the Symfony *request*
+    event.
+
+After Middleware
+~~~~~~~~~~~~~~~~
+
+An *after* application middleware allows you to tweak the Response before it
+is sent to the client::
+
+    $app->after(function (Request $request, Response $response) {
+        // ...
+    });
+
+.. note::
+
+    The after middleware is an event registered on the Symfony *response*
+    event.
+
+Finish Middleware
+~~~~~~~~~~~~~~~~~
+
+A *finish* application middleware allows you to execute tasks after the
+Response has been sent to the client (like sending emails or logging)::
+
+    $app->finish(function (Request $request, Response $response) {
+        // ...
+        // Warning: modifications to the Request or Response will be ignored
+    });
+
+.. note::
+
+    The finish middleware is an event registered on the Symfony *terminate*
+    event.
+
+Route Middleware
+----------------
+
+Route middleware is added to routes or route collections and it is only
+triggered when the corresponding route is matched. You can also stack them::
+
+    $app->get('/somewhere', function () {
+        // ...
+    })
+    ->before($before1)
+    ->before($before2)
+    ->after($after1)
+    ->after($after2)
+    ;
+
+Before Middleware
+~~~~~~~~~~~~~~~~~
+
+A *before* route middleware is fired just before the route callback, but after
+the *before* application middleware::
+
+    $before = function (Request $request, Application $app) {
+        // ...
+    };
+
+    $app->get('/somewhere', function () {
+        // ...
+    })
+    ->before($before);
+
+After Middleware
+~~~~~~~~~~~~~~~~
+
+An *after* route middleware is fired just after the route callback, but before
+the application *after* application middleware::
+
+    $after = function (Request $request, Response $response, Application $app) {
+        // ...
+    };
+
+    $app->get('/somewhere', function () {
+        // ...
+    })
+    ->after($after);
+
+Middleware Priority
+-------------------
+
+You can add as much middleware as you want, in which case they are triggered
+in the same order as you added them.
+
+You can explicitly control the priority of your middleware by passing an
+additional argument to the registration methods::
+
+    $app->before(function (Request $request) {
+        // ...
+    }, 32);
+
+As a convenience, two constants allow you to register an event as early as
+possible or as late as possible::
+
+    $app->before(function (Request $request) {
+        // ...
+    }, Application::EARLY_EVENT);
+
+    $app->before(function (Request $request) {
+        // ...
+    }, Application::LATE_EVENT);
+
+Short-circuiting the Controller
+-------------------------------
+
+If a *before* middleware returns a ``Response`` object, the request handling is
+short-circuited (the next middleware won't be run, nor the route
+callback), and the Response is passed to the *after* middleware right away::
+
+    $app->before(function (Request $request) {
+        // redirect the user to the login screen if access to the Resource is protected
+        if (...) {
+            return new RedirectResponse('/login');
+        }
+    });
+
+.. note::
+
+    A ``RuntimeException`` is thrown if a before middleware does not return a
+    Response or ``null``.

+Organizing Controllers
+======================
+
+When your application starts to define too many controllers, you might want to
+group them logically::
+
+    // define controllers for a blog
+    $blog = $app['controllers_factory'];
+    $blog->get('/', function () {
+        return 'Blog home page';
+    });
+    // ...
+
+    // define controllers for a forum
+    $forum = $app['controllers_factory'];
+    $forum->get('/', function () {
+        return 'Forum home page';
+    });
+
+    // define "global" controllers
+    $app->get('/', function () {
+        return 'Main home page';
+    });
+
+    $app->mount('/blog', $blog);
+    $app->mount('/forum', $forum);
+
+    // define controllers for a admin
+    $app->mount('/admin', function ($admin) {
+        // recursively mount
+        $admin->mount('/blog', function ($user) {
+            $user->get('/', function () {
+                return 'Admin Blog home page';
+            });
+        });
+    });
+
+.. note::
+
+    ``$app['controllers_factory']`` is a factory that returns a new instance
+    of ``ControllerCollection`` when used.
+
+``mount()`` prefixes all routes with the given prefix and merges them into the
+main Application. So, ``/`` will map to the main home page, ``/blog/`` to the
+blog home page, ``/forum/`` to the forum home page, and ``/admin/blog/`` to the
+admin blog home page.
+
+.. caution::
+
+    When mounting a route collection under ``/blog``, it is not possible to
+    define a route for the ``/blog`` URL. The shortest possible URL is
+    ``/blog/``.
+
+.. note::
+
+    When calling ``get()``, ``match()``, or any other HTTP methods on the
+    Application, you are in fact calling them on a default instance of
+    ``ControllerCollection`` (stored in ``$app['controllers']``).
+
+Another benefit is the ability to apply settings on a set of controllers very
+easily. Building on the example from the middleware section, here is how you
+would secure all controllers for the backend collection::
+
+    $backend = $app['controllers_factory'];
+
+    // ensure that all controllers require logged-in users
+    $backend->before($mustBeLogged);
+
+.. tip::
+
+    For a better readability, you can split each controller collection into a
+    separate file::
+
+        // blog.php
+        $blog = $app['controllers_factory'];
+        $blog->get('/', function () { return 'Blog home page'; });
+
+        return $blog;
+
+        // app.php
+        $app->mount('/blog', include 'blog.php');
+
+    Instead of requiring a file, you can also create a :ref:`Controller
+    provider <controller-providers>`.

+Providers
+=========
+
+Providers allow the developer to reuse parts of an application into another
+one. Silex provides two types of providers defined by two interfaces:
+``ServiceProviderInterface`` for services and ``ControllerProviderInterface``
+for controllers.
+
+Service Providers
+-----------------
+
+Loading providers
+~~~~~~~~~~~~~~~~~
+
+In order to load and use a service provider, you must register it on the
+application::
+
+    $app = new Silex\Application();
+
+    $app->register(new Acme\DatabaseServiceProvider());
+
+You can also provide some parameters as a second argument. These will be set
+**after** the provider is registered, but **before** it is booted::
+
+    $app->register(new Acme\DatabaseServiceProvider(), array(
+        'database.dsn'      => 'mysql:host=localhost;dbname=myapp',
+        'database.user'     => 'root',
+        'database.password' => 'secret_root_password',
+    ));
+
+Conventions
+~~~~~~~~~~~
+
+You need to watch out in what order you do certain things when interacting
+with providers. Just keep these rules in mind:
+
+* Overriding existing services must occur **after** the provider is
+  registered.
+
+  *Reason: If the service already exists, the provider will overwrite it.*
+
+* You can set parameters any time **after** the provider is registered, but
+  **before** the service is accessed.
+
+  *Reason: Providers can set default values for parameters. Just like with
+  services, the provider will overwrite existing values.*
+
+Included providers
+~~~~~~~~~~~~~~~~~~
+
+There are a few providers that you get out of the box. All of these are within
+the ``Silex\Provider`` namespace:
+
+* :doc:`DoctrineServiceProvider <providers/doctrine>`
+* :doc:`FormServiceProvider <providers/form>`
+* :doc:`HttpCacheServiceProvider <providers/http_cache>`
+* :doc:`MonologServiceProvider <providers/monolog>`
+* :doc:`RememberMeServiceProvider <providers/remember_me>`
+* :doc:`SecurityServiceProvider <providers/security>`
+* :doc:`SerializerServiceProvider <providers/serializer>`
+* :doc:`ServiceControllerServiceProvider <providers/service_controller>`
+* :doc:`SessionServiceProvider <providers/session>`
+* :doc:`SwiftmailerServiceProvider <providers/swiftmailer>`
+* :doc:`TranslationServiceProvider <providers/translation>`
+* :doc:`TwigServiceProvider <providers/twig>`
+* :doc:`ValidatorServiceProvider <providers/validator>`
+
+.. note::
+
+    The Silex core team maintains a `WebProfiler
+    <https://github.com/silexphp/Silex-WebProfiler>`_ provider that helps debug
+    code in the development environment thanks to the Symfony web debug toolbar
+    and the Symfony profiler.
+
+Third party providers
+~~~~~~~~~~~~~~~~~~~~~
+
+Some service providers are developed by the community. Those third-party
+providers are listed on `Silex' repository wiki
+<https://github.com/silexphp/Silex/wiki/Third-Party-ServiceProviders-for-Silex-2.x>`_.
+
+You are encouraged to share yours.
+
+Creating a provider
+~~~~~~~~~~~~~~~~~~~
+
+Providers must implement the ``Pimple\ServiceProviderInterface``::
+
+    interface ServiceProviderInterface
+    {
+        public function register(Container $container);
+    }
+
+This is very straight forward, just create a new class that implements the
+register method. In the ``register()`` method, you can define services on the
+application which then may make use of other services and parameters. 
+
+.. tip::
+
+    The ``Pimple\ServiceProviderInterface`` belongs to the Pimple package, so
+    take care to only use the API of ``Pimple\Container`` within your
+    ``register`` method. Not only is this a good practice due to the way Pimple
+    and Silex work, but may allow your provider to be used outside of Silex.
+
+Optionally, your service provider can implement the
+``Silex\Api\BootableProviderInterface``. A bootable provider must
+implement the ``boot()`` method, with which you can configure the application, just
+before it handles a request::
+
+    interface BootableProviderInterface
+    {
+        function boot(Application $app);
+    }
+
+Another optional interface, is the ``Silex\Api\EventListenerProviderInterface``.
+This interface contains the ``subscribe()`` method, which allows your provider to
+subscribe event listener with Silex's EventDispatcher, just before it handles a
+request::
+
+    interface EventListenerProviderInterface
+    {
+        function subscribe(Container $app, EventDispatcherInterface $dispatcher);
+    }
+
+Here is an example of such a provider::
+
+    namespace Acme;
+
+    use Pimple\Container;
+    use Pimple\ServiceProviderInterface;
+    use Silex\Application;
+    use Silex\Api\BootableProviderInterface;
+    use Silex\Api\EventListenerProviderInterface;
+    use Symfony\Component\EventDispatcher\EventDispatcherInterface;
+    use Symfony\Component\HttpKernel\KernelEvents;
+    use Symfony\Component\HttpKernel\Event\FilterResponseEvent;
+
+    class HelloServiceProvider implements ServiceProviderInterface, BootableProviderInterface, EventListenerProviderInterface
+    {
+        public function register(Container $app)
+        {
+            $app['hello'] = $app->protect(function ($name) use ($app) {
+                $default = $app['hello.default_name'] ? $app['hello.default_name'] : '';
+                $name = $name ?: $default;
+
+                return 'Hello '.$app->escape($name);
+            });
+        }
+
+        public function boot(Application $app)
+        {
+            // do something 
+        }
+
+        public function subscribe(Container $app, EventDispatcherInterface $dispatcher)
+        {
+            $dispatcher->addListener(KernelEvents::REQUEST, function(FilterResponseEvent $event) use ($app) {
+                // do something 
+            });
+        }
+    }
+
+This class provides a ``hello`` service which is a protected closure. It takes
+a ``name`` argument and will return ``hello.default_name`` if no name is
+given. If the default is also missing, it will use an empty string.
+
+You can now use this provider as follows::
+
+    use Symfony\Component\HttpFoundation\Request;
+
+    $app = new Silex\Application();
+
+    $app->register(new Acme\HelloServiceProvider(), array(
+        'hello.default_name' => 'Igor',
+    ));
+
+    $app->get('/hello', function (Request $request) use ($app) {
+        $name = $request->get('name');
+
+        return $app['hello']($name);
+    });
+
+In this example we are getting the ``name`` parameter from the query string,
+so the request path would have to be ``/hello?name=Fabien``.
+
+.. _controller-providers:
+
+Controller Providers
+--------------------
+
+Loading providers
+~~~~~~~~~~~~~~~~~
+
+In order to load and use a controller provider, you must "mount" its
+controllers under a path::
+
+    $app = new Silex\Application();
+
+    $app->mount('/blog', new Acme\BlogControllerProvider());
+
+All controllers defined by the provider will now be available under the
+``/blog`` path.
+
+Creating a provider
+~~~~~~~~~~~~~~~~~~~
+
+Providers must implement the ``Silex\Api\ControllerProviderInterface``::
+
+    interface ControllerProviderInterface
+    {
+        public function connect(Application $app);
+    }
+
+Here is an example of such a provider::
+
+    namespace Acme;
+
+    use Silex\Application;
+    use Silex\Api\ControllerProviderInterface;
+
+    class HelloControllerProvider implements ControllerProviderInterface
+    {
+        public function connect(Application $app)
+        {
+            // creates a new controller based on the default route
+            $controllers = $app['controllers_factory'];
+
+            $controllers->get('/', function (Application $app) {
+                return $app->redirect('/hello');
+            });
+
+            return $controllers;
+        }
+    }
+
+The ``connect`` method must return an instance of ``ControllerCollection``.
+``ControllerCollection`` is the class where all controller related methods are
+defined (like ``get``, ``post``, ``match``, ...).
+
+.. tip::
+
+    The ``Application`` class acts in fact as a proxy for these methods.
+
+You can use this provider as follows::
+
+    $app = new Silex\Application();
+
+    $app->mount('/blog', new Acme\HelloControllerProvider());
+
+In this example, the ``/blog/`` path now references the controller defined in
+the provider.
+
+.. tip::
+
+    You can also define a provider that implements both the service and the
+    controller provider interface and package in the same class the services
+    needed to make your controllers work.

+
+* **assets.packages**: The asset service.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\AssetServiceProvider(), array(
+        'assets.version' => 'v1',
+        'assets.version_format' => '%s?version=%s',

+            'images' => array('base_urls' => array('https://img.example.com')),
+        ),
+    ));
+
+.. note::
+
+    Add the Symfony Asset Component as a dependency:
+
+    .. code-block:: bash
+
+        composer require symfony/asset
+
+    If you want to use assets in your Twig templates, you must also install the
+    Symfony Twig Bridge:
+
+    .. code-block:: bash
+
+        composer require symfony/twig-bridge
+
+Usage
+-----
+
+The AssetServiceProvider is mostly useful with the Twig provider:
+
+.. code-block:: jinja
+
+    {{ asset('/css/foo.png') }}
+    {{ asset('/css/foo.css', 'css') }}
+    {{ asset('/img/foo.png', 'images') }}
+

+Doctrine
+========
+
+The *DoctrineServiceProvider* provides integration with the `Doctrine DBAL
+<http://www.doctrine-project.org/projects/dbal>`_ for easy database access
+(Doctrine ORM integration is **not** supplied).
+
+Parameters
+----------
+
+* **db.options**: Array of Doctrine DBAL options.
+
+  These options are available:
+
+  * **driver**: The database driver to use, defaults to ``pdo_mysql``.
+    Can be any of: ``pdo_mysql``, ``pdo_sqlite``, ``pdo_pgsql``,
+    ``pdo_oci``, ``oci8``, ``ibm_db2``, ``pdo_ibm``, ``pdo_sqlsrv``.
+
+  * **dbname**: The name of the database to connect to.
+
+  * **host**: The host of the database to connect to. Defaults to
+    localhost.
+
+  * **user**: The user of the database to connect to. Defaults to
+    root.
+
+  * **password**: The password of the database to connect to.
+
+  * **charset**: Only relevant for ``pdo_mysql``, and ``pdo_oci/oci8``,
+    specifies the charset used when connecting to the database.
+
+  * **path**: Only relevant for ``pdo_sqlite``, specifies the path to
+    the SQLite database.
+
+  * **port**: Only relevant for ``pdo_mysql``, ``pdo_pgsql``, and ``pdo_oci/oci8``,
+    specifies the port of the database to connect to.
+
+  These and additional options are described in detail in the `Doctrine DBAL
+  configuration documentation <http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html>`_.
+
+Services
+--------
+
+* **db**: The database connection, instance of
+  ``Doctrine\DBAL\Connection``.
+
+* **db.config**: Configuration object for Doctrine. Defaults to
+  an empty ``Doctrine\DBAL\Configuration``.
+
+* **db.event_manager**: Event Manager for Doctrine.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\DoctrineServiceProvider(), array(
+        'db.options' => array(
+            'driver'   => 'pdo_sqlite',
+            'path'     => __DIR__.'/app.db',
+        ),
+    ));
+
+.. note::
+
+    Add the Doctrine DBAL as a dependency:
+
+    .. code-block:: bash
+
+        composer require "doctrine/dbal:~2.2"
+
+Usage
+-----
+
+The Doctrine provider provides a ``db`` service. Here is a usage
+example::
+
+    $app->get('/blog/{id}', function ($id) use ($app) {
+        $sql = "SELECT * FROM posts WHERE id = ?";
+        $post = $app['db']->fetchAssoc($sql, array((int) $id));
+
+        return  "<h1>{$post['title']}</h1>".
+                "<p>{$post['body']}</p>";
+    });
+
+Using multiple databases
+------------------------
+
+The Doctrine provider can allow access to multiple databases. In order to
+configure the data sources, replace the **db.options** with **dbs.options**.
+**dbs.options** is an array of configurations where keys are connection names
+and values are options::
+
+    $app->register(new Silex\Provider\DoctrineServiceProvider(), array(
+        'dbs.options' => array (
+            'mysql_read' => array(
+                'driver'    => 'pdo_mysql',
+                'host'      => 'mysql_read.someplace.tld',
+                'dbname'    => 'my_database',
+                'user'      => 'my_username',
+                'password'  => 'my_password',
+                'charset'   => 'utf8mb4',
+            ),
+            'mysql_write' => array(
+                'driver'    => 'pdo_mysql',
+                'host'      => 'mysql_write.someplace.tld',
+                'dbname'    => 'my_database',
+                'user'      => 'my_username',
+                'password'  => 'my_password',
+                'charset'   => 'utf8mb4',
+            ),
+        ),
+    ));
+
+The first registered connection is the default and can simply be accessed as
+you would if there was only one connection. Given the above configuration,
+these two lines are equivalent::
+
+    $app['db']->fetchAll('SELECT * FROM table');
+
+    $app['dbs']['mysql_read']->fetchAll('SELECT * FROM table');
+
+Using multiple connections::
+
+    $app->get('/blog/{id}', function ($id) use ($app) {
+        $sql = "SELECT * FROM posts WHERE id = ?";
+        $post = $app['dbs']['mysql_read']->fetchAssoc($sql, array((int) $id));
+
+        $sql = "UPDATE posts SET value = ? WHERE id = ?";
+        $app['dbs']['mysql_write']->executeUpdate($sql, array('newValue', (int) $id));
+
+        return  "<h1>{$post['title']}</h1>".
+                "<p>{$post['body']}</p>";
+    });
+
+For more information, consult the `Doctrine DBAL documentation
+<http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/>`_.

+Form
+====
+
+The *FormServiceProvider* provides a service for building forms in
+your application with the Symfony Form component.
+
+Parameters
+----------
+
+* none
+
+Services
+--------
+
+* **form.factory**: An instance of `FormFactory
+  <http://api.symfony.com/master/Symfony/Component/Form/FormFactory.html>`_,
+  that is used to build a form.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    use Silex\Provider\FormServiceProvider;
+
+    $app->register(new FormServiceProvider());
+
+.. note::
+
+    If you don't want to create your own form layout, it's fine: a default one
+    will be used. But you will have to register the :doc:`translation provider
+    <translation>` as the default form layout requires it::
+
+        $app->register(new Silex\Provider\TranslationServiceProvider(), array(
+            'translator.domains' => array(),
+        ));
+
+    If you want to use validation with forms, do not forget to register the
+    :doc:`Validator provider <validator>`.
+
+.. note::
+
+    Add the Symfony Form Component as a dependency:
+
+    .. code-block:: bash
+
+        composer require symfony/form
+
+    If you are going to use the validation extension with forms, you must also
+    add a dependency to the ``symfony/config`` and ``symfony/translation``
+    components:
+
+    .. code-block:: bash
+
+        composer require symfony/validator symfony/config symfony/translation
+
+    If you want to use forms in your Twig templates, you can also install the
+    Symfony Twig Bridge. Make sure to install, if you didn't do that already,
+    the Translation component in order for the bridge to work:
+
+    .. code-block:: bash
+
+        composer require symfony/twig-bridge symfony/config symfony/translation
+
+Usage
+-----
+
+The FormServiceProvider provides a ``form.factory`` service. Here is a usage
+example::
+
+    use Symfony\Component\Form\Extension\Core\Type\FormType;
+    use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
+
+    $app->match('/form', function (Request $request) use ($app) {
+        // some default data for when the form is displayed the first time
+        $data = array(
+            'name' => 'Your name',
+            'email' => 'Your email',
+        );
+
+        $form = $app['form.factory']->createBuilder(FormType::class, $data)
+            ->add('name')
+            ->add('email')
+            ->add('billing_plan', ChoiceType::class, array(
+                'choices' => array(1 => 'free', 2 => 'small_business', 3 => 'corporate'),
+                'expanded' => true,
+            ))
+            ->getForm();
+
+        $form->handleRequest($request);
+
+        if ($form->isValid()) {
+            $data = $form->getData();
+
+            // do something with the data
+
+            // redirect somewhere
+            return $app->redirect('...');
+        }
+
+        // display the form
+        return $app['twig']->render('index.twig', array('form' => $form->createView()));
+    });
+
+And here is the ``index.twig`` form template (requires ``symfony/twig-bridge``):
+
+.. code-block:: jinja
+
+    <form action="#" method="post">
+        {{ form_widget(form) }}
+
+        <input type="submit" name="submit" />
+    </form>
+
+If you are using the validator provider, you can also add validation to your
+form by adding constraints on the fields::
+
+    use Symfony\Component\Form\Extension\Core\Type\FormType;
+    use Symfony\Component\Form\Extension\Core\Type\TextType;
+    use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    $app->register(new Silex\Provider\ValidatorServiceProvider());
+    $app->register(new Silex\Provider\TranslationServiceProvider(), array(
+        'translator.domains' => array(),
+    ));
+
+    $form = $app['form.factory']->createBuilder(FormType::class)
+        ->add('name', TextType::class, array(
+            'constraints' => array(new Assert\NotBlank(), new Assert\Length(array('min' => 5)))
+        ))
+        ->add('email', TextType::class, array(
+            'constraints' => new Assert\Email()
+        ))
+        ->add('billing_plan', ChoiceType::class, array(
+            'choices' => array(1 => 'free', 2 => 'small_business', 3 => 'corporate'),
+            'expanded' => true,
+            'constraints' => new Assert\Choice(array(1, 2, 3)),
+        ))
+        ->getForm();
+

+HTTP Cache
+==========
+
+The *HttpCacheServiceProvider* provides support for the Symfony Reverse
+Proxy.
+
+Parameters
+----------
+
+* **http_cache.cache_dir**: The cache directory to store the HTTP cache data.
+
+* **http_cache.options** (optional): An array of options for the `HttpCache
+  <http://api.symfony.com/master/Symfony/Component/HttpKernel/HttpCache/HttpCache.html>`_
+  constructor.
+
+Services
+--------
+
+* **http_cache**: An instance of `HttpCache
+  <http://api.symfony.com/master/Symfony/Component/HttpKernel/HttpCache/HttpCache.html>`_.
+
+* **http_cache.esi**: An instance of `Esi
+  <http://api.symfony.com/master/Symfony/Component/HttpKernel/HttpCache/Esi.html>`_,
+  that implements the ESI capabilities to Request and Response instances.
+
+* **http_cache.store**: An instance of `Store
+  <http://api.symfony.com/master/Symfony/Component/HttpKernel/HttpCache/Store.html>`_,
+  that implements all the logic for storing cache metadata (Request and Response
+  headers).
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\HttpCacheServiceProvider(), array(
+        'http_cache.cache_dir' => __DIR__.'/cache/',
+    ));
+
+Usage
+-----
+
+Silex already supports any reverse proxy like Varnish out of the box by
+setting Response HTTP cache headers::
+
+    use Symfony\Component\HttpFoundation\Response;
+
+    $app->get('/', function() {
+        return new Response('Foo', 200, array(
+            'Cache-Control' => 's-maxage=5',
+        ));
+    });
+
+.. tip::
+
+    If you want Silex to trust the ``X-Forwarded-For*`` headers from your
+    reverse proxy at address $ip, you will need to whitelist it as documented
+    in `Trusting Proxies
+    <http://symfony.com/doc/current/components/http_foundation/trusting_proxies.html>`_.
+
+    If you would be running Varnish in front of your application on the same machine::
+
+        use Symfony\Component\HttpFoundation\Request;
+        
+        Request::setTrustedProxies(array('127.0.0.1', '::1'));
+        $app->run();
+
+This provider allows you to use the Symfony reverse proxy natively with
+Silex applications by using the ``http_cache`` service. The Symfony reverse proxy
+acts much like any other proxy would, so you will want to whitelist it::
+
+    use Symfony\Component\HttpFoundation\Request;
+        
+    Request::setTrustedProxies(array('127.0.0.1'));
+    $app['http_cache']->run();
+
+The provider also provides ESI support::
+
+    $app->get('/', function() {
+        $response = new Response(<<<EOF
+    <html>
+        <body>
+            Hello
+            <esi:include src="/included" />
+        </body>
+    </html>
+
+    EOF
+        , 200, array(
+            'Surrogate-Control' => 'content="ESI/1.0"',
+        ));
+
+        $response->setTtl(20);
+
+        return $response;
+    });
+
+    $app->get('/included', function() {
+        $response = new Response('Foo');
+        $response->setTtl(5);
+
+        return $response;
+    });
+
+    $app['http_cache']->run();
+
+If your application doesn't use ESI, you can disable it to slightly improve the
+overall performance::
+
+    $app->register(new Silex\Provider\HttpCacheServiceProvider(), array(
+       'http_cache.cache_dir' => __DIR__.'/cache/',
+       'http_cache.esi'       => null,
+    ));
+
+.. tip::
+
+    To help you debug caching issues, set your application ``debug`` to true.
+    Symfony automatically adds a ``X-Symfony-Cache`` header to each response
+    with useful information about cache hits and misses.
+
+    If you are *not* using the Symfony Session provider, you might want to set
+    the PHP ``session.cache_limiter`` setting to an empty value to avoid the
+    default PHP behavior.
+
+    Finally, check that your Web server does not override your caching strategy.
+
+For more information, consult the `Symfony HTTP Cache documentation
+<http://symfony.com/doc/current/book/http_cache.html>`_.

+HTTP Fragment
+=============
+
+The *HttpFragmentServiceProvider* provides support for the Symfony fragment
+sub-framework, which allows you to embed fragments of HTML in a template.
+
+Parameters
+----------
+
+* **fragment.path**: The path to use for the URL generated for ESI and
+  HInclude URLs (``/_fragment`` by default).
+
+* **uri_signer.secret**: The secret to use for the URI signer service (used
+  for the HInclude renderer).
+
+* **fragment.renderers.hinclude.global_template**: The content or Twig
+  template to use for the default content when using the HInclude renderer.
+
+Services
+--------
+
+* **fragment.handler**: An instance of `FragmentHandler
+  <http://api.symfony.com/master/Symfony/Component/HttpKernel/Fragment/FragmentHandler.html>`_.
+
+* **fragment.renderers**: An array of fragment renderers (by default, the
+  inline, ESI, and HInclude renderers are pre-configured).
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\HttpFragmentServiceProvider());
+
+Usage
+-----
+
+.. note::
+
+    This section assumes that you are using Twig for your templates.
+
+Instead of building a page out of a single request/controller/template, the
+fragment framework allows you to build a page from several
+controllers/sub-requests/sub-templates by using **fragments**.
+
+Including "sub-pages" in the main page can be done with the Twig ``render()``
+function:
+
+.. code-block:: jinja
+
+    The main page content.
+
+    {{ render('/foo') }}
+
+    The main page content resumes here.
+
+The ``render()`` call is replaced by the content of the ``/foo`` URL
+(internally, a sub-request is handled by Silex to render the sub-page).
+
+Instead of making internal sub-requests, you can also use the ESI (the
+sub-request is handled by a reverse proxy) or the HInclude strategies (the
+sub-request is handled by a web browser):
+
+.. code-block:: jinja
+
+    {{ render(url('route_name')) }}
+
+    {{ render_esi(url('route_name')) }}
+
+    {{ render_hinclude(url('route_name')) }}

+Monolog
+=======
+
+The *MonologServiceProvider* provides a default logging mechanism through
+Jordi Boggiano's `Monolog <https://github.com/Seldaek/monolog>`_ library.
+
+It will log requests and errors and allow you to add logging to your
+application. This allows you to debug and monitor the behaviour,
+even in production.
+
+Parameters
+----------
+
+* **monolog.logfile**: File where logs are written to.
+* **monolog.bubble**: (optional) Whether the messages that are handled can bubble up the stack or not.
+* **monolog.permission**: (optional) File permissions default (null), nothing change.
+
+* **monolog.level** (optional): Level of logging, defaults
+  to ``DEBUG``. Must be one of ``Logger::DEBUG``, ``Logger::INFO``,
+  ``Logger::WARNING``, ``Logger::ERROR``. ``DEBUG`` will log
+  everything, ``INFO`` will log everything except ``DEBUG``,
+  etc.
+
+  In addition to the ``Logger::`` constants, it is also possible to supply the
+  level in string form, for example: ``"DEBUG"``, ``"INFO"``, ``"WARNING"``,
+  ``"ERROR"``.
+
+* **monolog.name** (optional): Name of the monolog channel,
+  defaults to ``myapp``.
+
+* **monolog.exception.logger_filter** (optional): An anonymous function that
+  returns an error level for on uncaught exception that should be logged.
+
+* **monolog.use_error_handler** (optional): Whether errors and uncaught exceptions
+  should be handled by the Monolog ``ErrorHandler`` class and added to the log.
+  By default the error handler is enabled unless the application ``debug`` parameter
+  is set to true.
+
+  Please note that enabling the error handler may silence some errors,
+  ignoring the PHP ``display_errors`` configuration setting.
+
+Services
+--------
+
+* **monolog**: The monolog logger instance.
+
+  Example usage::
+
+    $app['monolog']->debug('Testing the Monolog logging.');
+
+* **monolog.listener**: An event listener to log requests, responses and errors.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\MonologServiceProvider(), array(
+        'monolog.logfile' => __DIR__.'/development.log',

+
+.. note::
+
+    Add Monolog as a dependency:
+
+    .. code-block:: bash
+
+        composer require monolog/monolog
+
+Usage
+-----
+
+The MonologServiceProvider provides a ``monolog`` service. You can use it to
+add log entries for any logging level through ``debug()``, ``info()``,
+``warning()`` and ``error()``::
+
+    use Symfony\Component\HttpFoundation\Response;
+
+    $app->post('/user', function () use ($app) {
+        // ...
+
+        $app['monolog']->info(sprintf("User '%s' registered.", $username));
+
+        return new Response('', 201);
+    });
+
+Customization
+-------------
+
+You can configure Monolog (like adding or changing the handlers) before using
+it by extending the ``monolog`` service::
+
+    $app->extend('monolog', function($monolog, $app) {
+        $monolog->pushHandler(...);
+
+        return $monolog;
+    });
+
+By default, all requests, responses and errors are logged by an event listener
+registered as a service called `monolog.listener`. You can replace or remove
+this service if you want to modify or disable the logged information.
+
+Traits
+------
+
+``Silex\Application\MonologTrait`` adds the following shortcuts:
+
+* **log**: Logs a message.
+
+.. code-block:: php
+
+    $app->log(sprintf("User '%s' registered.", $username));
+
+For more information, check out the `Monolog documentation
+<https://github.com/Seldaek/monolog>`_.

+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\SecurityServiceProvider(), array(
+        'security.firewalls' => // see below
+    ));
+
+.. note::
+
+    Add the Symfony Security Component as a dependency:
+
+    .. code-block:: bash
+
+        composer require symfony/security
+
+.. caution::
+
+    If you're using a form to authenticate users, you need to enable
+    ``SessionServiceProvider``.
+
+.. caution::
+
+    The security features are only available after the Application has been
+    booted. So, if you want to use it outside of the handling of a request,
+    don't forget to call ``boot()`` first::
+
+        $app->boot();
+
+Usage
+-----
+
+The Symfony Security component is powerful. To learn more about it, read the
+`Symfony Security documentation
+<http://symfony.com/doc/2.8/book/security.html>`_.
+
+.. tip::
+
+    When a security configuration does not behave as expected, enable logging
+    (with the Monolog extension for instance) as the Security Component logs a
+    lot of interesting information about what it does and why.
+
+Below is a list of recipes that cover some common use cases.
+
+Accessing the current User
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The current user information is stored in a token that is accessible via the
+``security`` service::
+
+    $token = $app['security.token_storage']->getToken();
+
+If there is no information about the user, the token is ``null``. If the user
+is known, you can get it with a call to ``getUser()``::
+
+    if (null !== $token) {
+        $user = $token->getUser();
+    }
+
+The user can be a string, an object with a ``__toString()`` method, or an
+instance of `UserInterface
+<http://api.symfony.com/master/Symfony/Component/Security/Core/User/UserInterface.html>`_.
+
+Securing a Path with HTTP Authentication
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following configuration uses HTTP basic authentication to secure URLs
+under ``/admin/``::
+
+    $app['security.firewalls'] = array(
+        'admin' => array(
+            'pattern' => '^/admin',
+            'http' => true,
+            'users' => array(
+                // raw password is foo
+                'admin' => array('ROLE_ADMIN', '$2y$10$3i9/lVd8UOFIJ6PAMFt8gu3/r5g0qeCJvoSlLCsvMTythye19F77a'),
+            ),
+        ),
+    );
+
+The ``pattern`` is a regular expression on the URL path; the ``http`` setting
+tells the security layer to use HTTP basic authentication and the ``users``
+entry defines valid users.
+
+If you want to restrict the firewall by more than the URL pattern (like the
+HTTP method, the client IP, the hostname, or any Request attributes), use an
+instance of a `RequestMatcher
+<http://api.symfony.com/master/Symfony/Component/HttpFoundation/RequestMatcher.html>`_
+for the ``pattern`` option::
+
+    use Symfony/Component/HttpFoundation/RequestMatcher;
+
+    $app['security.firewalls'] = array(
+        'admin' => array(
+            'pattern' => new RequestMatcher('^/admin', 'example.com', 'POST'),
+            // ...
+        ),
+    );
+
+Each user is defined with the following information:
+
+* The role or an array of roles for the user (roles are strings beginning with
+  ``ROLE_`` and ending with anything you want);
+
+* The user encoded password.
+
+.. caution::
+
+    All users must at least have one role associated with them.
+
+The default configuration of the extension enforces encoded passwords. To
+generate a valid encoded password from a raw password, use the
+``security.encoder_factory`` service::
+
+    // find the encoder for a UserInterface instance
+    $encoder = $app['security.encoder_factory']->getEncoder($user);
+
+    // compute the encoded password for foo
+    $password = $encoder->encodePassword('foo', $user->getSalt());
+
+When the user is authenticated, the user stored in the token is an instance of
+`User
+<http://api.symfony.com/master/Symfony/Component/Security/Core/User/User.html>`_
+
+.. caution::
+
+    If you are using php-cgi under Apache, you need to add this configuration
+    to make things work correctly:
+
+    .. code-block:: apache
+
+        RewriteEngine On
+        RewriteCond %{HTTP:Authorization} ^(.+)$
+        RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
+        RewriteCond %{REQUEST_FILENAME} !-f
+        RewriteRule ^(.*)$ app.php [QSA,L]
+
+Securing a Path with a Form
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Using a form to authenticate users is very similar to the above configuration.
+Instead of using the ``http`` setting, use the ``form`` one and define these
+two parameters:
+
+* **login_path**: The login path where the user is redirected when they are
+  accessing a secured area without being authenticated so that they can enter
+  their credentials;
+
+* **check_path**: The check URL used by Symfony to validate the credentials of
+  the user.
+
+Here is how to secure all URLs under ``/admin/`` with a form::
+
+    $app['security.firewalls'] = array(
+        'admin' => array(
+            'pattern' => '^/admin/',
+            'form' => array('login_path' => '/login', 'check_path' => '/admin/login_check'),
+            'users' => array(
+                'admin' => array('ROLE_ADMIN', '$2y$10$3i9/lVd8UOFIJ6PAMFt8gu3/r5g0qeCJvoSlLCsvMTythye19F77a'),
+            ),
+        ),
+    );
+
+Always keep in mind the following two golden rules:
+
+* The ``login_path`` path must always be defined **outside** the secured area
+  (or if it is in the secured area, the ``anonymous`` authentication mechanism
+  must be enabled -- see below);
+
+* The ``check_path`` path must always be defined **inside** the secured area.
+
+For the login form to work, create a controller like the following::
+
+    use Symfony\Component\HttpFoundation\Request;
+
+    $app->get('/login', function(Request $request) use ($app) {
+        return $app['twig']->render('login.html', array(
+            'error'         => $app['security.last_error']($request),
+            'last_username' => $app['session']->get('_security.last_username'),
+        ));
+    });
+
+The ``error`` and ``last_username`` variables contain the last authentication
+error and the last username entered by the user in case of an authentication
+error.
+
+Create the associated template:
+
+.. code-block:: jinja
+
+    <form action="{{ path('admin_login_check') }}" method="post">
+        {{ error }}
+        <input type="text" name="_username" value="{{ last_username }}" />
+        <input type="password" name="_password" value="" />
+        <input type="submit" />
+    </form>
+
+.. note::
+
+    The ``admin_login_check`` route is automatically defined by Silex and its
+    name is derived from the ``check_path`` value (all ``/`` are replaced with
+    ``_`` and the leading ``/`` is stripped).
+
+Defining more than one Firewall
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You are not limited to define one firewall per project.
+
+Configuring several firewalls is useful when you want to secure different
+parts of your website with different authentication strategies or for
+different users (like using an HTTP basic authentication for the website API
+and a form to secure your website administration area).
+
+It's also useful when you want to secure all URLs except the login form::
+
+    $app['security.firewalls'] = array(
+        'login' => array(
+            'pattern' => '^/login$',
+        ),
+        'secured' => array(
+            'pattern' => '^.*$',
+            'form' => array('login_path' => '/login', 'check_path' => '/login_check'),
+            'users' => array(
+                'admin' => array('ROLE_ADMIN', '$2y$10$3i9/lVd8UOFIJ6PAMFt8gu3/r5g0qeCJvoSlLCsvMTythye19F77a'),
+            ),
+        ),
+    );
+
+The order of the firewall configurations is significant as the first one to
+match wins. The above configuration first ensures that the ``/login`` URL is
+not secured (no authentication settings), and then it secures all other URLs.
+
+.. tip::
+
+    You can toggle all registered authentication mechanisms for a particular
+    area on and off with the ``security`` flag::
+
+        $app['security.firewalls'] = array(
+            'api' => array(
+                'pattern' => '^/api',
+                'security' => $app['debug'] ? false : true,
+                'wsse' => true,
+
+                // ...
+            ),
+        );
+
+Adding a Logout
+~~~~~~~~~~~~~~~
+
+When using a form for authentication, you can let users log out if you add the
+``logout`` setting, where ``logout_path`` must match the main firewall
+pattern::
+
+    $app['security.firewalls'] = array(
+        'secured' => array(
+            'pattern' => '^/admin/',
+            'form' => array('login_path' => '/login', 'check_path' => '/admin/login_check'),
+            'logout' => array('logout_path' => '/admin/logout', 'invalidate_session' => true),
+
+            // ...
+        ),
+    );
+
+A route is automatically generated, based on the configured path (all ``/``
+are replaced with ``_`` and the leading ``/`` is stripped):
+
+.. code-block:: jinja
+
+    <a href="{{ path('admin_logout') }}">Logout</a>
+
+Allowing Anonymous Users
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+When securing only some parts of your website, the user information are not
+available in non-secured areas. To make the user accessible in such areas,
+enabled the ``anonymous`` authentication mechanism::
+
+    $app['security.firewalls'] = array(
+        'unsecured' => array(
+            'anonymous' => true,
+
+            // ...
+        ),
+    );
+
+When enabling the anonymous setting, a user will always be accessible from the
+security context; if the user is not authenticated, it returns the ``anon.``
+string.
+
+Checking User Roles
+~~~~~~~~~~~~~~~~~~~
+
+To check if a user is granted some role, use the ``isGranted()`` method on the
+security context::
+
+    if ($app['security.authorization_checker']->isGranted('ROLE_ADMIN')) {
+        // ...
+    }
+
+You can check roles in Twig templates too:
+
+.. code-block:: jinja
+
+    {% if is_granted('ROLE_ADMIN') %}
+        <a href="/secured?_switch_user=fabien">Switch to Fabien</a>
+    {% endif %}
+
+You can check if a user is "fully authenticated" (not an anonymous user for
+instance) with the special ``IS_AUTHENTICATED_FULLY`` role:
+
+.. code-block:: jinja
+
+    {% if is_granted('IS_AUTHENTICATED_FULLY') %}
+        <a href="{{ path('logout') }}">Logout</a>
+    {% else %}
+        <a href="{{ path('login') }}">Login</a>
+    {% endif %}
+
+Of course you will need to define a ``login`` route for this to work.
+
+.. tip::
+
+    Don't use the ``getRoles()`` method to check user roles.
+
+.. caution::
+
+    ``isGranted()`` throws an exception when no authentication information is
+    available (which is the case on non-secured area).
+
+Impersonating a User
+~~~~~~~~~~~~~~~~~~~~
+
+If you want to be able to switch to another user (without knowing the user
+credentials), enable the ``switch_user`` authentication strategy::
+
+    $app['security.firewalls'] = array(
+        'unsecured' => array(
+            'switch_user' => array('parameter' => '_switch_user', 'role' => 'ROLE_ALLOWED_TO_SWITCH'),
+
+            // ...
+        ),
+    );
+
+Switching to another user is now a matter of adding the ``_switch_user`` query
+parameter to any URL when logged in as a user who has the
+``ROLE_ALLOWED_TO_SWITCH`` role:
+
+.. code-block:: jinja
+
+    {% if is_granted('ROLE_ALLOWED_TO_SWITCH') %}
+        <a href="?_switch_user=fabien">Switch to user Fabien</a>
+    {% endif %}
+
+You can check that you are impersonating a user by checking the special
+``ROLE_PREVIOUS_ADMIN``. This is useful for instance to allow the user to
+switch back to their primary account:
+
+.. code-block:: jinja
+
+    {% if is_granted('ROLE_PREVIOUS_ADMIN') %}
+        You are an admin but you've switched to another user,
+        <a href="?_switch_user=_exit"> exit</a> the switch.
+    {% endif %}
+
+Defining a Role Hierarchy
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Defining a role hierarchy allows to automatically grant users some additional
+roles::
+
+    $app['security.role_hierarchy'] = array(
+        'ROLE_ADMIN' => array('ROLE_USER', 'ROLE_ALLOWED_TO_SWITCH'),
+    );
+
+With this configuration, all users with the ``ROLE_ADMIN`` role also
+automatically have the ``ROLE_USER`` and ``ROLE_ALLOWED_TO_SWITCH`` roles.
+
+Defining Access Rules
+~~~~~~~~~~~~~~~~~~~~~
+
+Roles are a great way to adapt the behavior of your website depending on
+groups of users, but they can also be used to further secure some areas by
+defining access rules::
+
+    $app['security.access_rules'] = array(
+        array('^/admin', 'ROLE_ADMIN', 'https'),
+        array('^.*$', 'ROLE_USER'),
+    );
+
+With the above configuration, users must have the ``ROLE_ADMIN`` to access the
+``/admin`` section of the website, and ``ROLE_USER`` for everything else.
+Furthermore, the admin section can only be accessible via HTTPS (if that's not
+the case, the user will be automatically redirected).
+
+.. note::
+
+    The first argument can also be a `RequestMatcher
+    <http://api.symfony.com/master/Symfony/Component/HttpFoundation/RequestMatcher.html>`_
+    instance.
+
+Defining a custom User Provider
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Using an array of users is simple and useful when securing an admin section of
+a personal website, but you can override this default mechanism with you own.
+
+The ``users`` setting can be defined as a service that returns an instance of
+`UserProviderInterface
+<http://api.symfony.com/master/Symfony/Component/Security/Core/User/UserProviderInterface.html>`_::
+
+    'users' => function () use ($app) {
+        return new UserProvider($app['db']);
+    },
+
+Here is a simple example of a user provider, where Doctrine DBAL is used to
+store the users::
+
+    use Symfony\Component\Security\Core\User\UserProviderInterface;
+    use Symfony\Component\Security\Core\User\UserInterface;
+    use Symfony\Component\Security\Core\User\User;
+    use Symfony\Component\Security\Core\Exception\UnsupportedUserException;
+    use Symfony\Component\Security\Core\Exception\UsernameNotFoundException;
+    use Doctrine\DBAL\Connection;
+
+    class UserProvider implements UserProviderInterface
+    {
+        private $conn;
+
+        public function __construct(Connection $conn)
+        {
+            $this->conn = $conn;
+        }
+
+        public function loadUserByUsername($username)
+        {
+            $stmt = $this->conn->executeQuery('SELECT * FROM users WHERE username = ?', array(strtolower($username)));
+
+            if (!$user = $stmt->fetch()) {
+                throw new UsernameNotFoundException(sprintf('Username "%s" does not exist.', $username));
+            }
+
+            return new User($user['username'], $user['password'], explode(',', $user['roles']), true, true, true, true);
+        }
+
+        public function refreshUser(UserInterface $user)
+        {
+            if (!$user instanceof User) {
+                throw new UnsupportedUserException(sprintf('Instances of "%s" are not supported.', get_class($user)));
+            }
+
+            return $this->loadUserByUsername($user->getUsername());
+        }
+
+        public function supportsClass($class)
+        {
+            return $class === 'Symfony\Component\Security\Core\User\User';
+        }
+    }
+
+In this example, instances of the default ``User`` class are created for the
+users, but you can define your own class; the only requirement is that the
+class must implement `UserInterface
+<http://api.symfony.com/master/Symfony/Component/Security/Core/User/UserInterface.html>`_
+
+And here is the code that you can use to create the database schema and some
+sample users::
+
+    use Doctrine\DBAL\Schema\Table;
+
+    $schema = $app['db']->getSchemaManager();
+    if (!$schema->tablesExist('users')) {
+        $users = new Table('users');
+        $users->addColumn('id', 'integer', array('unsigned' => true, 'autoincrement' => true));
+        $users->setPrimaryKey(array('id'));
+        $users->addColumn('username', 'string', array('length' => 32));
+        $users->addUniqueIndex(array('username'));
+        $users->addColumn('password', 'string', array('length' => 255));
+        $users->addColumn('roles', 'string', array('length' => 255));
+
+        $schema->createTable($users);
+
+        $app['db']->insert('users', array(
+          'username' => 'fabien',
+          'password' => '$2y$10$3i9/lVd8UOFIJ6PAMFt8gu3/r5g0qeCJvoSlLCsvMTythye19F77a',
+          'roles' => 'ROLE_USER'
+        ));
+
+        $app['db']->insert('users', array(
+          'username' => 'admin',
+          'password' => '$2y$10$3i9/lVd8UOFIJ6PAMFt8gu3/r5g0qeCJvoSlLCsvMTythye19F77a',
+          'roles' => 'ROLE_ADMIN'
+        ));
+    }
+
+.. tip::
+
+    If you are using the Doctrine ORM, the Symfony bridge for Doctrine
+    provides a user provider class that is able to load users from your
+    entities.
+
+Defining a custom Encoder
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, Silex uses the ``BCrypt`` algorithm to encode passwords.
+Additionally, the password is encoded multiple times.
+You can change these defaults by overriding ``security.default_encoder``
+service to return one of the predefined encoders:
+
+* **security.encoder.digest**: Digest password encoder.
+
+* **security.encoder.bcrypt**: BCrypt password encoder.
+
+* **security.encoder.pbkdf2**: Pbkdf2 password encoder.
+
+.. code-block:: php
+
+    $app['security.default_encoder'] = function ($app) {
+        return $app['security.encoder.pbkdf2'];
+    };
+
+Or you can define you own, fully customizable encoder::
+
+    use Symfony\Component\Security\Core\Encoder\PlaintextPasswordEncoder;
+
+    $app['security.default_encoder'] = function ($app) {
+        // Plain text (e.g. for debugging)
+        return new PlaintextPasswordEncoder();
+    };
+
+.. tip::
+
+    You can change the default BCrypt encoding cost by overriding ``security.encoder.bcrypt.cost``
+
+Defining a custom Authentication Provider
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Symfony Security component provides a lot of ready-to-use authentication
+providers (form, HTTP, X509, remember me, ...), but you can add new ones
+easily. To register a new authentication provider, create a service named
+``security.authentication_listener.factory.XXX`` where ``XXX`` is the name you want to
+use in your configuration::
+
+    $app['security.authentication_listener.factory.wsse'] = $app->protect(function ($name, $options) use ($app) {
+        // define the authentication provider object
+        $app['security.authentication_provider.'.$name.'.wsse'] = function () use ($app) {
+            return new WsseProvider($app['security.user_provider.default'], __DIR__.'/security_cache');
+        };
+
+        // define the authentication listener object
+        $app['security.authentication_listener.'.$name.'.wsse'] = function () use ($app) {
+            return new WsseListener($app['security.token_storage'], $app['security.authentication_manager']);
+        };
+
+        return array(
+            // the authentication provider id
+            'security.authentication_provider.'.$name.'.wsse',
+            // the authentication listener id
+            'security.authentication_listener.'.$name.'.wsse',
+            // the entry point id
+            null,
+            // the position of the listener in the stack
+            'pre_auth'
+        );
+    });
+
+You can now use it in your configuration like any other built-in
+authentication provider::
+
+    $app->register(new Silex\Provider\SecurityServiceProvider(), array(
+        'security.firewalls' => array(
+            'default' => array(
+                'wsse' => true,
+
+                // ...
+            ),
+        ),
+    ));
+
+Instead of ``true``, you can also define an array of options that customize
+the behavior of your authentication factory; it will be passed as the second
+argument of your authentication factory (see above).
+
+This example uses the authentication provider classes as described in the
+Symfony `cookbook`_.
+
+
+.. note::
+
+    The Guard component simplifies the creation of custom authentication
+    providers. :doc:`How to Create a Custom Authentication System with Guard
+    </cookbook/guard_authentication>`
+
+Stateless Authentication
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, a session cookie is created to persist the security context of
+the user. However, if you use certificates, HTTP authentication, WSSE and so
+on, the credentials are sent for each request. In that case, you can turn off
+persistence by activating the ``stateless`` authentication flag::
+
+    $app['security.firewalls'] = array(
+        'default' => array(
+            'stateless' => true,
+            'wsse' => true,
+
+            // ...
+        ),
+    );
+
+Traits
+------
+
+``Silex\Application\SecurityTrait`` adds the following shortcuts:
+
+* **encodePassword**: Encode a given password.
+
+.. code-block:: php
+
+    $user = $app->user();
+
+    $encoded = $app->encodePassword($user, 'foo');
+
+``Silex\Route\SecurityTrait`` adds the following methods to the controllers:
+
+* **secure**: Secures a controller for the given roles.
+
+.. code-block:: php
+
+    $app->get('/', function () {
+        // do something but only for admins
+    })->secure('ROLE_ADMIN');
+
+.. caution::
+
+    The ``Silex\Route\SecurityTrait`` must be used with a user defined
+    ``Route`` class, not the application.
+
+    .. code-block:: php
+
+        use Silex\Route;
+
+        class MyRoute extends Route
+        {
+            use Route\SecurityTrait;
+        }
+
+    .. code-block:: php
+
+        $app['route_class'] = 'MyRoute';

+Service Controllers
+===================
+
+As your Silex application grows, you may wish to begin organizing your
+controllers in a more formal fashion. Silex can use controller classes out of
+the box, but with a bit of work, your controllers can be created as services,
+giving you the full power of dependency injection and lazy loading.

+  Using this method, you can inject the actual dependencies required by your
+  controller and gain total inversion of control, while still maintaining the
+  lazy loading of your controllers and its dependencies. Because your
+  dependencies are clearly defined, they are easily mocked, allowing you to test
+  your controllers in isolation.
+
+- Framework Independence
+
+  Using this method, your controllers start to become more independent of the
+  framework you are using. Carefully crafted, your controllers will become
+  reusable with multiple frameworks. By keeping careful control of your
+  dependencies, your controllers could easily become compatible with Silex,
+  Symfony (full stack) and Drupal, to name just a few.
+
+Parameters
+----------
+
+There are currently no parameters for the ``ServiceControllerServiceProvider``.
+
+Services
+--------
+
+There are no extra services provided, the ``ServiceControllerServiceProvider``
+simply extends the existing **resolver** service.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\ServiceControllerServiceProvider());
+
+Usage
+-----
+
+In this slightly contrived example of a blog API, we're going to change the
+``/posts.json`` route to use a controller, that is defined as a service.
+
+.. code-block:: php
+
+    use Silex\Application;
+    use Demo\Repository\PostRepository;
+
+    $app = new Application();
+
+    $app['posts.repository'] = function() {
+        return new PostRepository;
+    };
+
+    $app->get('/posts.json', function() use ($app) {
+        return $app->json($app['posts.repository']->findAll());
+    });
+
+Rewriting your controller as a service is pretty simple, create a Plain Ol' PHP
+Object with your ``PostRepository`` as a dependency, along with an
+``indexJsonAction`` method to handle the request. Although not shown in the
+example below, you can use type hinting and parameter naming to get the
+parameters you need, just like with standard Silex routes.
+
+If you are a TDD/BDD fan (and you should be), you may notice that this
+controller has well defined responsibilities and dependencies, and is easily
+tested/specced. You may also notice that the only external dependency is on
+``Symfony\Component\HttpFoundation\JsonResponse``, meaning this controller could
+easily be used in a Symfony (full stack) application, or potentially with other
+applications or frameworks that know how to handle a `Symfony/HttpFoundation
+<http://symfony.com/doc/master/components/http_foundation/introduction.html>`_
+``Response`` object.
+
+.. code-block:: php
+
+    namespace Demo\Controller;
+
+    use Demo\Repository\PostRepository;
+    use Symfony\Component\HttpFoundation\JsonResponse;
+
+    class PostController
+    {
+        protected $repo;
+
+        public function __construct(PostRepository $repo)
+        {
+            $this->repo = $repo;
+        }
+
+        public function indexJsonAction()
+        {
+            return new JsonResponse($this->repo->findAll());
+        }
+    }
+
+And lastly, define your controller as a service in the application, along with
+your route. The syntax in the route definition is the name of the service,
+followed by a single colon (:), followed by the method name.
+
+.. code-block:: php
+
+    $app['posts.controller'] = function() use ($app) {
+        return new PostController($app['posts.repository']);
+    };
+
+    $app->get('/posts.json', "posts.controller:indexJsonAction");
+
+In addition to using classes for service controllers, you can define any
+callable as a service in the application to be used for a route.
+
+.. code-block:: php
+
+    namespace Demo\Controller;
+
+    use Demo\Repository\PostRepository;
+    use Symfony\Component\HttpFoundation\JsonResponse;
+
+    function postIndexJson(PostRepository $repo) {
+        return function() use ($repo) {
+            return new JsonResponse($repo->findAll());
+        };
+    }
+
+And when defining your route, the code would look like the following:
+
+.. code-block:: php
+
+    $app['posts.controller'] = function($app) {
+        return Demo\Controller\postIndexJson($app['posts.repository']);
+    };
+
+    $app->get('/posts.json', 'posts.controller');

+Session
+=======
+
+The *SessionServiceProvider* provides a service for storing data persistently
+between requests.
+
+Parameters
+----------
+
+* **session.storage.save_path** (optional): The path for the
+  ``NativeFileSessionHandler``, defaults to the value of
+  ``sys_get_temp_dir()``.
+
+* **session.storage.options**: An array of options that is passed to the
+  constructor of the ``session.storage`` service.
+
+  In case of the default `NativeSessionStorage
+  <http://api.symfony.com/master/Symfony/Component/HttpFoundation/Session/Storage/NativeSessionStorage.html>`_,
+  the most useful options are:
+
+  * **name**: The cookie name (_SESS by default)
+  * **id**: The session id (null by default)
+  * **cookie_lifetime**: Cookie lifetime
+  * **cookie_path**: Cookie path
+  * **cookie_domain**: Cookie domain
+  * **cookie_secure**: Cookie secure (HTTPS)
+  * **cookie_httponly**: Whether the cookie is http only
+
+  However, all of these are optional. Default Sessions life time is 1800
+  seconds (30 minutes). To override this, set the ``lifetime`` option.
+
+  For a full list of available options, read the `PHP
+  <http://php.net/session.configuration>`_ official documentation.
+
+* **session.test**: Whether to simulate sessions or not (useful when writing
+  functional tests).
+
+Services
+--------
+
+* **session**: An instance of Symfony's `Session
+  <http://api.symfony.com/master/Symfony/Component/HttpFoundation/Session/Session.html>`_.
+
+* **session.storage**: A service that is used for persistence of the session
+  data.
+
+* **session.storage.handler**: A service that is used by the
+  ``session.storage`` for data access. Defaults to a `NativeFileSessionHandler
+  <http://api.symfony.com/master/Symfony/Component/HttpFoundation/Session/Storage/Handler/NativeFileSessionHandler.html>`_
+  storage handler.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\SessionServiceProvider());
+
+Usage
+-----
+
+The Session provider provides a ``session`` service. Here is an example that
+authenticates a user and creates a session for them::
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpFoundation\Response;
+
+    $app->get('/login', function (Request $request) use ($app) {
+        $username = $request->server->get('PHP_AUTH_USER', false);
+        $password = $request->server->get('PHP_AUTH_PW');
+
+        if ('igor' === $username && 'password' === $password) {
+            $app['session']->set('user', array('username' => $username));
+            return $app->redirect('/account');
+        }
+
+        $response = new Response();
+        $response->headers->set('WWW-Authenticate', sprintf('Basic realm="%s"', 'site_login'));
+        $response->setStatusCode(401, 'Please sign in.');
+        return $response;
+    });
+
+    $app->get('/account', function () use ($app) {
+        if (null === $user = $app['session']->get('user')) {
+            return $app->redirect('/login');
+        }
+
+        return "Welcome {$user['username']}!";
+    });
+
+
+Custom Session Configurations
+-----------------------------
+
+If your system is using a custom session configuration (such as a redis handler
+from a PHP extension) then you need to disable the NativeFileSessionHandler by
+setting ``session.storage.handler`` to null. You will have to configure the
+``session.save_path`` ini setting yourself in that case.
+
+.. code-block:: php
+
+    $app['session.storage.handler'] = null;

+Swiftmailer
+===========
+
+The *SwiftmailerServiceProvider* provides a service for sending email through
+the `Swift Mailer <http://swiftmailer.org>`_ library.
+
+You can use the ``mailer`` service to send messages easily. By default, it
+will attempt to send emails through SMTP.
+
+Parameters
+----------
+
+* **swiftmailer.use_spool**: A boolean to specify whether or not to use the
+  memory spool, defaults to true.
+
+* **swiftmailer.options**: An array of options for the default SMTP-based
+  configuration.
+
+  The following options can be set:
+
+  * **host**: SMTP hostname, defaults to 'localhost'.
+  * **port**: SMTP port, defaults to 25.
+  * **username**: SMTP username, defaults to an empty string.
+  * **password**: SMTP password, defaults to an empty string.
+  * **encryption**: SMTP encryption, defaults to null. Valid values are 'tls', 'ssl', or null (indicating no encryption).
+  * **auth_mode**: SMTP authentication mode, defaults to null. Valid values are 'plain', 'login', 'cram-md5', or null.
+
+  Example usage::
+
+    $app['swiftmailer.options'] = array(
+        'host' => 'host',
+        'port' => '25',
+        'username' => 'username',
+        'password' => 'password',
+        'encryption' => null,
+        'auth_mode' => null
+    );
+
+* **swiftmailer.sender_address**: If set, all messages will be delivered with
+  this address as the "return path" address.
+
+* **swiftmailer.delivery_addresses**: If not empty, all email messages will be
+  sent to those addresses instead of being sent to their actual recipients. This
+  is often useful when developing.
+
+* **swiftmailer.delivery_whitelist**: Used in combination with
+  ``delivery_addresses``. If set, emails matching any of these patterns will be
+  delivered like normal, as well as being sent to ``delivery_addresses``.
+
+Services
+--------
+
+* **mailer**: The mailer instance.
+
+  Example usage::
+
+    $message = \Swift_Message::newInstance();
+
+    // ...
+
+    $app['mailer']->send($message);
+
+* **swiftmailer.transport**: The transport used for e-mail
+  delivery. Defaults to a ``Swift_Transport_EsmtpTransport``.
+
+* **swiftmailer.transport.buffer**: StreamBuffer used by
+  the transport.
+
+* **swiftmailer.transport.authhandler**: Authentication
+  handler used by the transport. Will try the following
+  by default: CRAM-MD5, login, plaintext.
+
+* **swiftmailer.transport.eventdispatcher**: Internal event
+  dispatcher used by Swiftmailer.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\SwiftmailerServiceProvider());
+
+.. note::
+
+    Add SwiftMailer as a dependency:
+
+    .. code-block:: bash
+
+        composer require swiftmailer/swiftmailer
+
+Usage
+-----
+
+The Swiftmailer provider provides a ``mailer`` service::
+
+    use Symfony\Component\HttpFoundation\Request;
+
+    $app->post('/feedback', function (Request $request) use ($app) {
+        $message = \Swift_Message::newInstance()
+            ->setSubject('[YourSite] Feedback')
+            ->setFrom(array('noreply@yoursite.com'))
+            ->setTo(array('feedback@yoursite.com'))
+            ->setBody($request->get('message'));
+
+        $app['mailer']->send($message);
+
+        return new Response('Thank you for your feedback!', 201);
+    });
+
+Usage in commands
+~~~~~~~~~~~~~~~~~
+
+By default, the Swiftmailer provider sends the emails using the ``KernelEvents::TERMINATE``
+event, which is fired after the response has been sent. However, as this event
+isn't fired for console commands, your emails won't be sent.
+
+For that reason, if you send emails using a command console, it is recommended
+that you disable the use of the memory spool (before accessing ``$app['mailer']``)::
+
+    $app['swiftmailer.use_spool'] = false;
+
+Alternatively, you can just make sure to flush the message spool by hand before
+ending the command execution. To do so, use the following code::
+
+    $app['swiftmailer.spooltransport']
+        ->getSpool()
+        ->flushQueue($app['swiftmailer.transport'])
+    ;
+
+Traits
+------
+
+``Silex\Application\SwiftmailerTrait`` adds the following shortcuts:
+
+* **mail**: Sends an email.
+
+.. code-block:: php
+
+    $app->mail(\Swift_Message::newInstance()
+        ->setSubject('[YourSite] Feedback')
+        ->setFrom(array('noreply@yoursite.com'))
+        ->setTo(array('feedback@yoursite.com'))
+        ->setBody($request->get('message')));

+
+    $app['translator.domains'] = array(
+        'messages' => array(
+            'en' => array(
+                'hello'     => 'Hello %name%',
+                'goodbye'   => 'Goodbye %name%',
+            ),
+            'de' => array(
+                'hello'     => 'Hallo %name%',
+                'goodbye'   => 'Tschüss %name%',

+                'hello'     => 'Bonjour %name%',
+                'goodbye'   => 'Au revoir %name%',
+            ),
+        ),

+
+    $app->get('/{_locale}/{message}/{name}', function ($message, $name) use ($app) {
+        return $app['translator']->trans($message, array('%name%' => $name));
+    });
+
+The above example will result in following routes:
+
+* ``/en/hello/igor`` will return ``Hello igor``.
+
+* ``/de/hello/igor`` will return ``Hallo igor``.
+
+* ``/fr/hello/igor`` will return ``Bonjour igor``.
+
+* ``/it/hello/igor`` will return ``Hello igor`` (because of the fallback).
+
+Using Resources
+---------------
+
+When translations are stored in a file, you can load them as follows::
+
+    $app = new Application();
+    
+    $app->register(new TranslationServiceProvider());
+    $app->extend('translator.resources', function ($resources, $app) {
+        $resources = array_merge($resources, array(
+            array('array', array('This value should be a valid number.' => 'Cette valeur doit être un nombre.'), 'fr', 'validators'),
+        ));
+
+        return $resources;
+    });
+
+Traits
+------
+
+``Silex\Application\TranslationTrait`` adds the following shortcuts:
+
+* **trans**: Translates the given message.
+
+* **transChoice**: Translates the given choice message by choosing a
+  translation according to a number.
+
+.. code-block:: php
+
+    $app->trans('Hello World');
+
+    $app->transChoice('Hello World');
+
+Recipes
+-------
+
+YAML-based language files
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Having your translations in PHP files can be inconvenient. This recipe will
+show you how to load translations from external YAML files.
+
+First, add the Symfony ``Config`` and ``Yaml`` components as dependencies:
+
+.. code-block:: bash
+
+    composer require symfony/config symfony/yaml
+
+Next, you have to create the language mappings in YAML files. A naming you can
+use is ``locales/en.yml``. Just do the mapping in this file as follows:
+
+.. code-block:: yaml
+
+    hello: Hello %name%
+    goodbye: Goodbye %name%
+
+Then, register the ``YamlFileLoader`` on the ``translator`` and add all your
+translation files::
+
+    use Symfony\Component\Translation\Loader\YamlFileLoader;
+
+    $app->extend('translator', function($translator, $app) {
+        $translator->addLoader('yaml', new YamlFileLoader());
+
+        $translator->addResource('yaml', __DIR__.'/locales/en.yml', 'en');
+        $translator->addResource('yaml', __DIR__.'/locales/de.yml', 'de');
+        $translator->addResource('yaml', __DIR__.'/locales/fr.yml', 'fr');
+
+        return $translator;
+    });
+
+XLIFF-based language files
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Just as you would do with YAML translation files, you first need to add the
+Symfony ``Config`` component as a dependency (see above for details).
+
+Then, similarly, create XLIFF files in your locales directory and add them to
+the translator::
+
+    $translator->addResource('xliff', __DIR__.'/locales/en.xlf', 'en');
+    $translator->addResource('xliff', __DIR__.'/locales/de.xlf', 'de');
+    $translator->addResource('xliff', __DIR__.'/locales/fr.xlf', 'fr');
+
+.. note::
+
+    The XLIFF loader is already pre-configured by the extension.
+
+Accessing translations in Twig templates
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Once loaded, the translation service provider is available from within Twig
+templates when using the Twig bridge provided by Symfony (see
+:doc:`TwigServiceProvider </providers/twig>`):
+
+.. code-block:: jinja
+
+    {{ 'translation_key'|trans }}
+    {{ 'translation_key'|transchoice }}
+    {% trans %}translation_key{% endtrans %}

+Twig
+====
+
+The *TwigServiceProvider* provides integration with the `Twig
+<http://twig.sensiolabs.org/>`_ template engine.
+
+Parameters
+----------
+
+* **twig.path** (optional): Path to the directory containing twig template
+  files (it can also be an array of paths).
+
+* **twig.templates** (optional): An associative array of template names to
+  template contents. Use this if you want to define your templates inline.
+
+* **twig.options** (optional): An associative array of twig
+  options. Check out the `twig documentation <http://twig.sensiolabs.org/doc/api.html#environment-options>`_
+  for more information.

+
+    composer require symfony/twig-bridge
+
+When present, the ``TwigServiceProvider`` will provide you with the following
+additional capabilities.
+
+* Access to the ``path()`` and ``url()`` functions. You can find more
+  information in the `Symfony Routing documentation
+  <http://symfony.com/doc/current/book/routing.html#generating-urls-from-a-template>`_:
+
+  .. code-block:: jinja
+  
+      {{ path('homepage') }}
+      {{ url('homepage') }} {# generates the absolute url http://example.org/ #}
+      {{ path('hello', {name: 'Fabien'}) }}
+      {{ url('hello', {name: 'Fabien'}) }} {# generates the absolute url http://example.org/hello/Fabien #}
+
+* Access to the ``absolute_url()`` and ``relative_path()`` Twig functions.
+
+Translations Support
+~~~~~~~~~~~~~~~~~~~~
+
+If you are using the ``TranslationServiceProvider``, you will get the
+``trans()`` and ``transchoice()`` functions for translation in Twig templates.
+You can find more information in the `Symfony Translation documentation

+If you are using the ``FormServiceProvider``, you will get a set of helpers for
+working with forms in templates. You can find more information in the `Symfony
+Forms reference
+<http://symfony.com/doc/current/reference/forms/twig_reference.html>`_.
+
+Security Support
+~~~~~~~~~~~~~~~~
+
+If you are using the ``SecurityServiceProvider``, you will have access to the
+``is_granted()`` function in templates. You can find more information in the
+`Symfony Security documentation
+<http://symfony.com/doc/current/book/security.html#access-control-in-templates>`_.
+
+Global Variable
+~~~~~~~~~~~~~~~
+
+When the Twig bridge is available, the ``global`` variable refers to an
+instance of `AppVariable <http://api.symfony.com/master/Symfony/Bridge/Twig/AppVariable.html>`_.
+It gives access to the following methods:
+
+.. code-block:: jinja
+
+    {# The current Request #}
+    {{ global.request }}
+
+    {# The current User (when security is enabled) #}
+    {{ global.user }}
+
+    {# The current Session #}
+    {{ global.session }}
+
+    {# The debug flag #}
+    {{ global.debug }}
+
+Rendering a Controller
+~~~~~~~~~~~~~~~~~~~~~~
+
+A ``render`` function is also registered to help you render another controller
+from a template (available when the :doc:`HttpFragment Service Provider
+</providers/http_fragment>` is registered):
+
+.. code-block:: jinja
+
+    {{ render(url('sidebar')) }}
+
+    {# or you can reference a controller directly without defining a route for it #}
+    {{ render(controller(controller)) }}
+
+.. note::
+
+    You must prepend the ``app.request.baseUrl`` to render calls to ensure
+    that the render works when deployed into a sub-directory of the docroot.
+
+.. note::
+
+    Read the Twig `reference`_ for Symfony document to learn more about the
+    various Twig functions.
+
+Traits
+------
+
+``Silex\Application\TwigTrait`` adds the following shortcuts:
+
+* **render**: Renders a view with the given parameters and returns a Response
+  object.
+
+.. code-block:: php
+
+    return $app->render('index.html', ['name' => 'Fabien']);
+
+    $response = new Response();
+    $response->setTtl(10);
+
+    return $app->render('index.html', ['name' => 'Fabien'], $response);
+
+.. code-block:: php
+
+    // stream a view
+    use Symfony\Component\HttpFoundation\StreamedResponse;
+
+    return $app->render('index.html', ['name' => 'Fabien'], new StreamedResponse());
+
+Customization
+-------------
+
+You can configure the Twig environment before using it by extending the
+``twig`` service::
+
+    $app->extend('twig', function($twig, $app) {
+        $twig->addGlobal('pi', 3.14);
+        $twig->addFilter('levenshtein', new \Twig_Filter_Function('levenshtein'));
+
+        return $twig;
+    });
+

+<http://twig.sensiolabs.org>`_.

+Validator
+=========
+
+The *ValidatorServiceProvider* provides a service for validating data. It is
+most useful when used with the *FormServiceProvider*, but can also be used
+standalone.
+
+Parameters
+----------
+
+* **validator.validator_service_ids**: An array of service names representing
+  validators.
+
+Services
+--------
+
+* **validator**: An instance of `Validator
+  <http://api.symfony.com/master/Symfony/Component/Validator/ValidatorInterface.html>`_.
+
+* **validator.mapping.class_metadata_factory**: Factory for metadata loaders,
+  which can read validation constraint information from classes. Defaults to
+  StaticMethodLoader--ClassMetadataFactory.
+
+  This means you can define a static ``loadValidatorMetadata`` method on your
+  data class, which takes a ClassMetadata argument. Then you can set
+  constraints on this ClassMetadata instance.
+
+Registering
+-----------
+
+.. code-block:: php
+
+    $app->register(new Silex\Provider\ValidatorServiceProvider());
+
+.. note::
+
+    Add the Symfony Validator Component as a dependency:
+
+    .. code-block:: bash
+
+        composer require symfony/validator
+
+Usage
+-----
+
+The Validator provider provides a ``validator`` service.
+
+Validating Values
+~~~~~~~~~~~~~~~~~
+
+You can validate values directly using the ``validate`` validator
+method::
+
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    $app->get('/validate/{email}', function ($email) use ($app) {
+        $errors = $app['validator']->validate($email, new Assert\Email());
+
+        if (count($errors) > 0) {
+            return (string) $errors;
+        } else {
+            return 'The email is valid';
+        }
+    });
+
+Validating Associative Arrays
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Validating associative arrays is like validating simple values, with a
+collection of constraints::
+
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    $book = array(
+        'title' => 'My Book',
+        'author' => array(
+            'first_name' => 'Fabien',
+            'last_name'  => 'Potencier',
+        ),
+    );
+
+    $constraint = new Assert\Collection(array(
+        'title' => new Assert\Length(array('min' => 10)),
+        'author' => new Assert\Collection(array(
+            'first_name' => array(new Assert\NotBlank(), new Assert\Length(array('min' => 10))),
+            'last_name'  => new Assert\Length(array('min' => 10)),
+        )),
+    ));
+    $errors = $app['validator']->validate($book, $constraint);
+
+    if (count($errors) > 0) {
+        foreach ($errors as $error) {
+            echo $error->getPropertyPath().' '.$error->getMessage()."\n";
+        }
+    } else {
+        echo 'The book is valid';
+    }
+
+Validating Objects
+~~~~~~~~~~~~~~~~~~
+
+If you want to add validations to a class, you can define the constraint for
+the class properties and getters, and then call the ``validate`` method::
+
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    class Book
+    {
+        public $title;
+        public $author;
+    }
+
+    class Author
+    {
+        public $first_name;
+        public $last_name;
+    }
+
+    $author = new Author();
+    $author->first_name = 'Fabien';
+    $author->last_name = 'Potencier';
+
+    $book = new Book();
+    $book->title = 'My Book';
+    $book->author = $author;
+
+    $metadata = $app['validator.mapping.class_metadata_factory']->getMetadataFor('Author');
+    $metadata->addPropertyConstraint('first_name', new Assert\NotBlank());
+    $metadata->addPropertyConstraint('first_name', new Assert\Length(array('min' => 10)));
+    $metadata->addPropertyConstraint('last_name', new Assert\Length(array('min' => 10)));
+
+    $metadata = $app['validator.mapping.class_metadata_factory']->getMetadataFor('Book');
+    $metadata->addPropertyConstraint('title', new Assert\Length(array('min' => 10)));
+    $metadata->addPropertyConstraint('author', new Assert\Valid());
+
+    $errors = $app['validator']->validate($book);
+
+    if (count($errors) > 0) {
+        foreach ($errors as $error) {
+            echo $error->getPropertyPath().' '.$error->getMessage()."\n";
+        }
+    } else {
+        echo 'The author is valid';
+    }
+
+You can also declare the class constraint by adding a static
+``loadValidatorMetadata`` method to your classes::
+
+    use Symfony\Component\Validator\Mapping\ClassMetadata;
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    class Book
+    {
+        public $title;
+        public $author;
+
+        static public function loadValidatorMetadata(ClassMetadata $metadata)
+        {
+            $metadata->addPropertyConstraint('title', new Assert\Length(array('min' => 10)));
+            $metadata->addPropertyConstraint('author', new Assert\Valid());
+        }
+    }
+
+    class Author
+    {
+        public $first_name;
+        public $last_name;
+
+        static public function loadValidatorMetadata(ClassMetadata $metadata)
+        {
+            $metadata->addPropertyConstraint('first_name', new Assert\NotBlank());
+            $metadata->addPropertyConstraint('first_name', new Assert\Length(array('min' => 10)));
+            $metadata->addPropertyConstraint('last_name', new Assert\Length(array('min' => 10)));
+        }
+    }
+
+    $app->get('/validate/{email}', function ($email) use ($app) {
+        $author = new Author();
+        $author->first_name = 'Fabien';
+        $author->last_name = 'Potencier';
+
+        $book = new Book();
+        $book->title = 'My Book';
+        $book->author = $author;
+
+        $errors = $app['validator']->validate($book);
+
+        if (count($errors) > 0) {
+            foreach ($errors as $error) {
+                echo $error->getPropertyPath().' '.$error->getMessage()."\n";
+            }
+        } else {
+            echo 'The author is valid';
+        }
+    });
+
+.. note::
+
+    Use ``addGetterConstraint()`` to add constraints on getter methods and
+    ``addConstraint()`` to add constraints on the class itself.
+
+Translation
+~~~~~~~~~~~
+
+To be able to translate the error messages, you can use the translator
+provider and register the messages under the ``validators`` domain::
+
+    $app['translator.domains'] = array(
+        'validators' => array(
+            'fr' => array(
+                'This value should be a valid number.' => 'Cette valeur doit être un nombre.',
+            ),
+        ),
+    );
+
+For more information, consult the `Symfony Validation documentation
+<http://symfony.com/doc/master/book/validation.html>`_.

+Var Dumper
+==========
+
+The *VarDumperServiceProvider* provides a mechanism that allows exploring then
+dumping any PHP variable.
+
+Parameters
+----------
+
+* **var_dumper.dump_destination**: A stream URL where dumps should be written
+  to (defaults to ``null``).
+
+Services
+--------
+
+* n/a
+

+    .. code-block:: bash
+
+        composer require symfony/var-dumper
+
+Usage
+-----
+
+Adding the VarDumper component as a Composer dependency gives you access to the
+``dump()`` PHP function anywhere in your code.
+
+If you are using Twig, it also provides a ``dump()`` Twig function and a
+``dump`` Twig tag.
+
+The VarDumperServiceProvider is also useful when used with the Silex
+WebProfiler as the dumps are made available in the web debug toolbar and in the
+web profiler.

+Services
+========
+
+Silex is not only a framework, it is also a service container. It does this by
+extending `Pimple <http://pimple.sensiolabs.org>`_ which provides a very simple
+service container.
+
+Dependency Injection
+--------------------
+
+.. note::
+
+    You can skip this if you already know what Dependency Injection is.
+
+Dependency Injection is a design pattern where you pass dependencies to
+services instead of creating them from within the service or relying on
+globals. This generally leads to code that is decoupled, re-usable, flexible
+and testable.
+
+Here is an example of a class that takes a ``User`` object and stores it as a
+file in JSON format::
+
+    class JsonUserPersister
+    {
+        private $basePath;
+
+        public function __construct($basePath)
+        {
+            $this->basePath = $basePath;
+        }
+
+        public function persist(User $user)
+        {
+            $data = $user->getAttributes();
+            $json = json_encode($data);
+            $filename = $this->basePath.'/'.$user->id.'.json';
+            file_put_contents($filename, $json, LOCK_EX);
+        }
+    }
+
+In this simple example the dependency is the ``basePath`` property. It is
+passed to the constructor. This means you can create several independent
+instances with different base paths. Of course dependencies do not have to be
+simple strings. More often they are in fact other services.
+
+A service container is responsible for creating and storing services. It can
+recursively create dependencies of the requested services and inject them. It
+does so lazily, which means a service is only created when you actually need it.
+
+Pimple
+------
+
+Pimple makes strong use of closures and implements the ArrayAccess interface.
+
+We will start off by creating a new instance of Pimple -- and because
+``Silex\Application`` extends ``Pimple\Container`` all of this applies to Silex
+as well::
+
+    $container = new Pimple\Container();
+
+or::
+
+    $app = new Silex\Application();
+
+Parameters
+~~~~~~~~~~
+
+You can set parameters (which are usually strings) by setting an array key on
+the container::
+
+    $app['some_parameter'] = 'value';
+
+The array key can be any value. By convention dots are used for namespacing::
+
+    $app['asset.host'] = 'http://cdn.mysite.com/';
+
+Reading parameter values is possible with the same syntax::
+
+    echo $app['some_parameter'];
+
+Service definitions
+~~~~~~~~~~~~~~~~~~~
+
+Defining services is no different than defining parameters. You just set an
+array key on the container to be a closure. However, when you retrieve the
+service, the closure is executed. This allows for lazy service creation::
+
+    $app['some_service'] = function () {
+        return new Service();
+    };
+
+And to retrieve the service, use::
+
+    $service = $app['some_service'];
+
+On first invocation, this will create the service; the same instance will then
+be returned on any subsequent access.
+
+Factory services
+~~~~~~~~~~~~~~~~
+
+If you want a different instance to be returned for each service access, wrap
+the service definition with the ``factory()`` method::
+
+    $app['some_service'] = $app->factory(function () {
+        return new Service();
+    });
+
+Every time you call ``$app['some_service']``, a new instance of the service is
+created.
+
+Access container from closure
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In many cases you will want to access the service container from within a
+service definition closure. For example when fetching services the current
+service depends on.
+
+Because of this, the container is passed to the closure as an argument::
+
+    $app['some_service'] = function ($app) {
+        return new Service($app['some_other_service'], $app['some_service.config']);
+    };
+
+Here you can see an example of Dependency Injection. ``some_service`` depends
+on ``some_other_service`` and takes ``some_service.config`` as configuration
+options. The dependency is only created when ``some_service`` is accessed, and
+it is possible to replace either of the dependencies by simply overriding
+those definitions.
+
+Going back to our initial example, here's how we could use the container
+to manage its dependencies::
+
+    $app['user.persist_path'] = '/tmp/users';
+    $app['user.persister'] = function ($app) {
+        return new JsonUserPersister($app['user.persist_path']);
+    };
+
+
+Protected closures
+~~~~~~~~~~~~~~~~~~
+
+Because the container sees closures as factories for services, it will always
+execute them when reading them.
+
+In some cases you will however want to store a closure as a parameter, so that
+you can fetch it and execute it yourself -- with your own arguments.
+
+This is why Pimple allows you to protect your closures from being executed, by
+using the ``protect`` method::
+
+    $app['closure_parameter'] = $app->protect(function ($a, $b) {
+        return $a + $b;
+    });
+
+    // will not execute the closure
+    $add = $app['closure_parameter'];
+
+    // calling it now
+    echo $add(2, 3);
+
+Note that protected closures do not get access to the container.
+
+Core services
+-------------
+
+Silex defines a range of services.
+
+* **request_stack**: Controls the lifecycle of requests, an instance of
+  `RequestStack <http://api.symfony.com/master/Symfony/Component/HttpFoundation/RequestStack.html>`_.
+  It gives you access to ``GET``, ``POST`` parameters and lots more!
+
+  Example usage::
+
+    $id = $app['request_stack']->getCurrentRequest()->get('id');
+
+  A request is only available when a request is being served; you can only
+  access it from within a controller, an application before/after middlewares,
+  or an error handler.
+
+* **routes**: The `RouteCollection
+  <http://api.symfony.com/master/Symfony/Component/Routing/RouteCollection.html>`_
+  that is used internally. You can add, modify, read routes.
+
+* **url_generator**: An instance of `UrlGenerator
+  <http://api.symfony.com/master/Symfony/Component/Routing/Generator/UrlGenerator.html>`_,
+  using the `RouteCollection
+  <http://api.symfony.com/master/Symfony/Component/Routing/RouteCollection.html>`_
+  that is provided through the ``routes`` service. It has a ``generate``
+  method, which takes the route name as an argument, followed by an array of
+  route parameters.
+
+* **controllers**: The ``Silex\ControllerCollection`` that is used internally.
+  Check the :doc:`Internals chapter <internals>` for more information.
+
+* **dispatcher**: The `EventDispatcher
+  <http://api.symfony.com/master/Symfony/Component/EventDispatcher/EventDispatcher.html>`_
+  that is used internally. It is the core of the Symfony system and is used
+  quite a bit by Silex.
+
+* **resolver**: The `ControllerResolver
+  <http://api.symfony.com/master/Symfony/Component/HttpKernel/Controller/ControllerResolver.html>`_
+  that is used internally. It takes care of executing the controller with the
+  right arguments.
+
+* **kernel**: The `HttpKernel
+  <http://api.symfony.com/master/Symfony/Component/HttpKernel/HttpKernel.html>`_
+  that is used internally. The HttpKernel is the heart of Symfony, it takes a
+  Request as input and returns a Response as output.
+
+* **request_context**: The request context is a simplified representation of
+  the request that is used by the router and the URL generator.
+
+* **exception_handler**: The Exception handler is the default handler that is
+  used when you don't register one via the ``error()`` method or if your
+  handler does not return a Response. Disable it with
+  ``unset($app['exception_handler'])``.
+
+* **logger**: A `LoggerInterface <https://github.com/php-fig/log/blob/master/Psr/Log/LoggerInterface.php>`_ instance. By default, logging is
+  disabled as the value is set to ``null``. To enable logging you can either use
+  the :doc:`MonologServiceProvider <providers/monolog>` or define your own ``logger`` service that
+  conforms to the PSR logger interface.
+
+Core traits
+-----------
+
+* ``Silex\Application\UrlGeneratorTrait`` adds the following shortcuts:
+
+  * **path**: Generates a path.
+
+  * **url**: Generates an absolute URL.
+
+  .. code-block:: php
+
+      $app->path('homepage');
+      $app->url('homepage');
+
+Core parameters
+---------------
+
+* **request.http_port** (optional): Allows you to override the default port
+  for non-HTTPS URLs. If the current request is HTTP, it will always use the
+  current port.
+
+  Defaults to 80.
+
+  This parameter can be used when generating URLs.
+
+* **request.https_port** (optional): Allows you to override the default port
+  for HTTPS URLs. If the current request is HTTPS, it will always use the
+  current port.
+
+  Defaults to 443.
+
+  This parameter can be used when generating URLs.
+
+* **debug** (optional): Returns whether or not the application is running in
+  debug mode.
+
+  Defaults to false.
+
+* **charset** (optional): The charset to use for Responses.
+
+  Defaults to UTF-8.

+Testing
+=======
+
+Because Silex is built on top of Symfony, it is very easy to write functional
+tests for your application. Functional tests are automated software tests that
+ensure that your code is working correctly. They go through the user interface,
+using a fake browser, and mimic the actions a user would do.
+
+Why
+---
+
+If you are not familiar with software tests, you may be wondering why you would
+need this. Every time you make a change to your application, you have to test
+it. This means going through all the pages and making sure they are still
+working. Functional tests save you a lot of time, because they enable you to
+test your application in usually under a second by running a single command.
+
+For more information on functional testing, unit testing, and automated
+software tests in general, check out `PHPUnit
+<https://github.com/sebastianbergmann/phpunit>`_ and `Bulat Shakirzyanov's talk
+on Clean Code <http://www.slideshare.net/avalanche123/clean-code-5609451>`_.
+
+PHPUnit
+-------
+
+`PHPUnit <https://github.com/sebastianbergmann/phpunit>`_ is the de-facto
+standard testing framework for PHP. It was built for writing unit tests, but it
+can be used for functional tests too. You write tests by creating a new class,
+that extends the ``PHPUnit_Framework_TestCase``. Your test cases are methods
+prefixed with ``test``::
+
+    class ContactFormTest extends \PHPUnit_Framework_TestCase
+    {
+        public function testInitialPage()
+        {
+            ...
+        }
+    }
+
+In your test cases, you do assertions on the state of what you are testing. In
+this case we are testing a contact form, so we would want to assert that the
+page loaded correctly and contains our form::
+
+        public function testInitialPage()
+        {
+            $statusCode = ...
+            $pageContent = ...
+
+            $this->assertEquals(200, $statusCode);
+            $this->assertContains('Contact us', $pageContent);
+            $this->assertContains('<form', $pageContent);
+        }
+
+Here you see some of the available assertions. There is a full list available
+in the `Writing Tests for PHPUnit
+<https://phpunit.de/manual/current/en/writing-tests-for-phpunit.html>`_
+section of the PHPUnit documentation.
+
+WebTestCase
+-----------
+
+Symfony provides a WebTestCase class that can be used to write functional
+tests. The Silex version of this class is ``Silex\WebTestCase``, and you can
+use it by making your test extend it::
+
+    use Silex\WebTestCase;
+
+    class ContactFormTest extends WebTestCase
+    {
+        ...
+    }
+
+.. caution::
+
+    If you need to override the ``setUp()`` method, don't forget to call the
+    parent (``parent::setUp()``) to call the Silex default setup.
+
+.. note::
+
+    If you want to use the Symfony ``WebTestCase`` class you will need to
+    explicitly install its dependencies for your project:
+
+    .. code-block:: bash
+
+        composer require --dev symfony/browser-kit symfony/css-selector
+
+For your WebTestCase, you will have to implement a ``createApplication``
+method, which returns your application instance::
+
+        public function createApplication()
+        {
+            // app.php must return an Application instance
+            return require __DIR__.'/path/to/app.php';
+        }
+
+Make sure you do **not** use ``require_once`` here, as this method will be
+executed before every test.
+
+.. tip::
+
+    By default, the application behaves in the same way as when using it from a
+    browser. But when an error occurs, it is sometimes easier to get raw
+    exceptions instead of HTML pages. It is rather simple if you tweak the
+    application configuration in the ``createApplication()`` method like
+    follows::
+
+        public function createApplication()
+        {
+            $app = require __DIR__.'/path/to/app.php';
+            $app['debug'] = true;
+            unset($app['exception_handler']);
+
+            return $app;
+        }
+
+.. tip::
+
+    If your application use sessions, set ``session.test`` to ``true`` to
+    simulate sessions::
+
+        public function createApplication()
+        {
+            // ...
+
+            $app['session.test'] = true;
+
+            // ...
+        }
+
+The WebTestCase provides a ``createClient`` method. A client acts as a browser,
+and allows you to interact with your application. Here's how it works::
+
+        public function testInitialPage()
+        {
+            $client = $this->createClient();
+            $crawler = $client->request('GET', '/');
+
+            $this->assertTrue($client->getResponse()->isOk());
+            $this->assertCount(1, $crawler->filter('h1:contains("Contact us")'));
+            $this->assertCount(1, $crawler->filter('form'));
+            ...
+        }
+
+There are several things going on here. You have both a ``Client`` and a
+``Crawler``.
+
+You can also access the application through ``$this->app``.
+
+Client
+~~~~~~
+
+The client represents a browser. It holds your browsing history, cookies and
+more. The ``request`` method allows you to make a request to a page on your
+application.
+
+.. note::
+
+    You can find some documentation for it in `the client section of the
+    testing chapter of the Symfony documentation
+    <http://symfony.com/doc/current/book/testing.html#the-test-client>`_.
+
+Crawler
+~~~~~~~
+
+The crawler allows you to inspect the content of a page. You can filter it
+using CSS expressions and lots more.
+
+.. note::
+
+    You can find some documentation for it in `the crawler section of the testing
+    chapter of the Symfony documentation
+    <http://symfony.com/doc/current/book/testing.html#the-test-client>`_.
+
+Configuration
+-------------
+
+The suggested way to configure PHPUnit is to create a ``phpunit.xml.dist``
+file, a ``tests`` folder and your tests in
+``tests/YourApp/Tests/YourTest.php``. The ``phpunit.xml.dist`` file should
+look like this:
+
+.. code-block:: xml
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <phpunit bootstrap="./vendor/autoload.php"
+             backupGlobals="false"
+             backupStaticAttributes="false"
+             colors="true"
+             convertErrorsToExceptions="true"
+             convertNoticesToExceptions="true"
+             convertWarningsToExceptions="true"
+             processIsolation="false"
+             stopOnFailure="false"
+             syntaxCheck="false"
+    >
+        <testsuites>
+            <testsuite name="YourApp Test Suite">
+                <directory>./tests/</directory>
+            </testsuite>
+        </testsuites>
+    </phpunit>
+
+Your ``tests/YourApp/Tests/YourTest.php`` should look like this::
+
+    namespace YourApp\Tests;
+
+    use Silex\WebTestCase;
+
+    class YourTest extends WebTestCase
+    {
+        public function createApplication()
+        {
+            return require __DIR__.'/../../../app.php';
+        }
+
+        public function testFooBar()
+        {
+            ...
+        }
+    }
+
+Now, when running ``phpunit`` on the command line, tests should run.

+Usage
+=====
+
+Installation
+------------
+
+If you want to get started fast, `download`_ Silex as an archive and extract
+it, you should have the following directory structure:
+
+.. code-block:: text
+
+    ├── composer.json
+    ├── composer.lock
+    ├── vendor
+    │   └── ...
+    └── web
+        └── index.php
+
+If you want more flexibility, use Composer_ instead:
+
+.. code-block:: bash
+
+    composer require silex/silex:~2.0
+
+Web Server
+----------
+
+All examples in the documentation rely on a well-configured web server; read
+the :doc:`webserver documentation<web_servers>` to check yours.
+
+Bootstrap
+---------
+
+To bootstrap Silex, all you need to do is require the ``vendor/autoload.php``
+file and create an instance of ``Silex\Application``. After your controller
+definitions, call the ``run`` method on your application::
+
+    // web/index.php
+    require_once __DIR__.'/../vendor/autoload.php';
+
+    $app = new Silex\Application();
+
+    // ... definitions
+
+    $app->run();
+
+.. tip::
+
+    When developing a website, you might want to turn on the debug mode to
+    ease debugging::
+
+        $app['debug'] = true;
+
+.. tip::
+
+    If your application is hosted behind a reverse proxy at address ``$ip``,
+    and you want Silex to trust the ``X-Forwarded-For*`` headers, you will
+    need to run your application like this::
+
+        use Symfony\Component\HttpFoundation\Request;
+
+        Request::setTrustedProxies(array($ip));
+        $app->run();
+
+Routing
+-------
+
+In Silex you define a route and the controller that is called when that
+route is matched. A route pattern consists of:
+
+* *Pattern*: The route pattern defines a path that points to a resource. The
+  pattern can include variable parts and you are able to set RegExp
+  requirements for them.
+
+* *Method*: One of the following HTTP methods: ``GET``, ``POST``, ``PUT``,
+  ``DELETE``, ``PATCH``, or ``OPTIONS``. This describes the interaction with
+  the resource.
+
+The controller is defined using a closure like this::
+
+    function () {
+        // ... do something
+    }
+
+The return value of the closure becomes the content of the page.
+
+Example GET Route
+~~~~~~~~~~~~~~~~~
+
+Here is an example definition of a ``GET`` route::
+
+    $blogPosts = array(
+        1 => array(
+            'date'      => '2011-03-29',
+            'author'    => 'igorw',
+            'title'     => 'Using Silex',
+            'body'      => '...',
+        ),
+    );
+
+    $app->get('/blog', function () use ($blogPosts) {
+        $output = '';
+        foreach ($blogPosts as $post) {
+            $output .= $post['title'];
+            $output .= '<br />';
+        }
+
+        return $output;
+    });
+
+Visiting ``/blog`` will return a list of blog post titles. The ``use``
+statement means something different in this context. It tells the closure to
+import the ``$blogPosts`` variable from the outer scope. This allows you to use
+it from within the closure.
+
+Dynamic Routing
+~~~~~~~~~~~~~~~
+
+Now, you can create another controller for viewing individual blog posts::
+
+    $app->get('/blog/{id}', function (Silex\Application $app, $id) use ($blogPosts) {
+        if (!isset($blogPosts[$id])) {
+            $app->abort(404, "Post $id does not exist.");
+        }
+
+        $post = $blogPosts[$id];
+
+        return  "<h1>{$post['title']}</h1>".
+                "<p>{$post['body']}</p>";
+    });
+
+This route definition has a variable ``{id}`` part which is passed to the
+closure.
+
+The current ``Application`` is automatically injected by Silex to the Closure
+thanks to the type hinting.
+
+When the post does not exist, you are using ``abort()`` to stop the request
+early. It actually throws an exception, which you will see how to handle later
+on.
+
+Example POST Route
+~~~~~~~~~~~~~~~~~~
+
+POST routes signify the creation of a resource. An example for this is a
+feedback form. You will use the ``mail`` function to send an e-mail::
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpFoundation\Response;
+
+    $app->post('/feedback', function (Request $request) {
+        $message = $request->get('message');
+        mail('feedback@yoursite.com', '[YourSite] Feedback', $message);
+
+        return new Response('Thank you for your feedback!', 201);
+    });
+
+It is pretty straightforward.
+
+.. note::
+
+    There is a :doc:`SwiftmailerServiceProvider <providers/swiftmailer>`
+    included that you can use instead of ``mail()``.
+
+The current ``request`` is automatically injected by Silex to the Closure
+thanks to the type hinting. It is an instance of
+Request_, so you can fetch variables using the request ``get`` method.
+
+Instead of returning a string you are returning an instance of Response_.
+This allows setting an HTTP status code, in this case it is set to
+``201 Created``.
+
+.. note::
+
+    Silex always uses a ``Response`` internally, it converts strings to
+    responses with status code ``200``.
+
+Other methods
+~~~~~~~~~~~~~
+
+You can create controllers for most HTTP methods. Just call one of these
+methods on your application: ``get``, ``post``, ``put``, ``delete``, ``patch``, ``options``::
+
+    $app->put('/blog/{id}', function ($id) {
+        // ...
+    });
+
+    $app->delete('/blog/{id}', function ($id) {
+        // ...
+    });
+
+    $app->patch('/blog/{id}', function ($id) {
+        // ...
+    });
+
+.. tip::
+
+    Forms in most web browsers do not directly support the use of other HTTP
+    methods. To use methods other than GET and POST you can utilize a special
+    form field with a name of ``_method``. The form's ``method`` attribute must
+    be set to POST when using this field:
+
+    .. code-block:: html
+
+        <form action="/my/target/route/" method="post">
+            <!-- ... -->
+            <input type="hidden" id="_method" name="_method" value="PUT" />
+        </form>
+
+    You need to explicitly enable this method override::
+
+        use Symfony\Component\HttpFoundation\Request;
+
+        Request::enableHttpMethodParameterOverride();
+        $app->run();
+
+You can also call ``match``, which will match all methods. This can be
+restricted via the ``method`` method::
+
+    $app->match('/blog', function () {
+        // ...
+    });
+
+    $app->match('/blog', function () {
+        // ...
+    })
+    ->method('PATCH');
+
+    $app->match('/blog', function () {
+        // ...
+    })
+    ->method('PUT|POST');
+
+.. note::
+
+    The order in which the routes are defined is significant. The first
+    matching route will be used, so place more generic routes at the bottom.
+
+Route Variables
+~~~~~~~~~~~~~~~
+
+As it has been shown before you can define variable parts in a route like
+this::
+
+    $app->get('/blog/{id}', function ($id) {
+        // ...
+    });
+
+It is also possible to have more than one variable part, just make sure the
+closure arguments match the names of the variable parts::
+
+    $app->get('/blog/{postId}/{commentId}', function ($postId, $commentId) {
+        // ...
+    });
+
+While it's not recommended, you could also do this (note the switched
+arguments)::
+
+    $app->get('/blog/{postId}/{commentId}', function ($commentId, $postId) {
+        // ...
+    });
+
+You can also ask for the current Request and Application objects::
+
+    $app->get('/blog/{id}', function (Application $app, Request $request, $id) {
+        // ...
+    });
+
+.. note::
+
+    Note for the Application and Request objects, Silex does the injection
+    based on the type hinting and not on the variable name::
+
+        $app->get('/blog/{id}', function (Application $foo, Request $bar, $id) {
+            // ...
+        });
+
+Route Variable Converters
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Before injecting the route variables into the controller, you can apply some
+converters::
+
+    $app->get('/user/{id}', function ($id) {
+        // ...
+    })->convert('id', function ($id) { return (int) $id; });
+
+This is useful when you want to convert route variables to objects as it
+allows to reuse the conversion code across different controllers::
+
+    $userProvider = function ($id) {
+        return new User($id);
+    };
+
+    $app->get('/user/{user}', function (User $user) {
+        // ...
+    })->convert('user', $userProvider);
+
+    $app->get('/user/{user}/edit', function (User $user) {
+        // ...
+    })->convert('user', $userProvider);
+
+The converter callback also receives the ``Request`` as its second argument::
+
+    $callback = function ($post, Request $request) {
+        return new Post($request->attributes->get('slug'));
+    };
+
+    $app->get('/blog/{id}/{slug}', function (Post $post) {
+        // ...
+    })->convert('post', $callback);
+
+A converter can also be defined as a service. For example, here is a user
+converter based on Doctrine ObjectManager::
+
+    use Doctrine\Common\Persistence\ObjectManager;
+    use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
+
+    class UserConverter
+    {
+        private $om;
+
+        public function __construct(ObjectManager $om)
+        {
+            $this->om = $om;
+        }
+
+        public function convert($id)
+        {
+            if (null === $user = $this->om->find('User', (int) $id)) {
+                throw new NotFoundHttpException(sprintf('User %d does not exist', $id));
+            }
+
+            return $user;
+        }
+    }
+
+The service will now be registered in the application, and the
+``convert()`` method will be used as converter (using the syntax
+``service_name:method_name``)::
+
+    $app['converter.user'] = function () {
+        return new UserConverter();
+    };
+
+    $app->get('/user/{user}', function (User $user) {
+        // ...
+    })->convert('user', 'converter.user:convert');
+
+Requirements
+~~~~~~~~~~~~
+
+In some cases you may want to only match certain expressions. You can define
+requirements using regular expressions by calling ``assert`` on the
+``Controller`` object, which is returned by the routing methods.
+
+The following will make sure the ``id`` argument is a positive integer, since
+``\d+`` matches any amount of digits::
+
+    $app->get('/blog/{id}', function ($id) {
+        // ...
+    })
+    ->assert('id', '\d+');
+
+You can also chain these calls::
+
+    $app->get('/blog/{postId}/{commentId}', function ($postId, $commentId) {
+        // ...
+    })
+    ->assert('postId', '\d+')
+    ->assert('commentId', '\d+');
+
+Conditions
+~~~~~~~~~~
+
+Besides restricting route matching based on the HTTP method or parameter
+requirements, you can set conditions on any part of the request by calling
+``when`` on the ``Controller`` object, which is returned by the routing
+methods::
+
+    $app->get('/blog/{id}', function ($id) {
+        // ...
+    })
+    ->when("request.headers.get('User-Agent') matches '/firefox/i'");
+
+The ``when`` argument is a Symfony Expression_ , which means that you need to
+add ``symfony/expression-language`` as a dependency of your project.
+
+Default Values
+~~~~~~~~~~~~~~
+
+You can define a default value for any route variable by calling ``value`` on
+the ``Controller`` object::
+
+    $app->get('/{pageName}', function ($pageName) {
+        // ...
+    })
+    ->value('pageName', 'index');
+
+This will allow matching ``/``, in which case the ``pageName`` variable will
+have the value ``index``.
+
+Named Routes
+~~~~~~~~~~~~
+
+Some providers can make use of named routes. By default Silex will generate an
+internal route name for you but you can give an explicit route name by calling
+``bind``::
+
+    $app->get('/', function () {
+        // ...
+    })
+    ->bind('homepage');
+
+    $app->get('/blog/{id}', function ($id) {
+        // ...
+    })
+    ->bind('blog_post');
+
+Controllers as Classes
+~~~~~~~~~~~~~~~~~~~~~~
+
+Instead of anonymous functions, you can also define your controllers as
+methods. By using the ``ControllerClass::methodName`` syntax, you can tell
+Silex to lazily create the controller object for you::
+
+    $app->get('/', 'Acme\\Foo::bar');
+
+    use Silex\Application;
+    use Symfony\Component\HttpFoundation\Request;
+
+    namespace Acme
+    {
+        class Foo
+        {
+            public function bar(Request $request, Application $app)
+            {
+                // ...
+            }
+        }
+    }
+
+This will load the ``Acme\Foo`` class on demand, create an instance and call
+the ``bar`` method to get the response. You can use ``Request`` and
+``Silex\Application`` type hints to get ``$request`` and ``$app`` injected.
+
+It is also possible to :doc:`define your controllers as services
+<providers/service_controller>`.
+
+Global Configuration
+--------------------
+
+If a controller setting must be applied to **all** controllers (a converter, a
+middleware, a requirement, or a default value), configure it on
+``$app['controllers']``, which holds all application controllers::
+
+    $app['controllers']
+        ->value('id', '1')
+        ->assert('id', '\d+')
+        ->requireHttps()
+        ->method('get')
+        ->convert('id', function () { /* ... */ })
+        ->before(function () { /* ... */ })
+        ->when('request.isSecure() == true')
+    ;
+
+These settings are applied to already registered controllers and they become
+the defaults for new controllers.
+
+.. note::
+
+    The global configuration does not apply to controller providers you might
+    mount as they have their own global configuration (read the
+    :doc:`dedicated chapter<organizing_controllers>` for more information).
+
+Error Handlers
+--------------
+
+When an exception is thrown, error handlers allow you to display a custom
+error page to the user. They can also be used to do additional things, such as
+logging.
+
+To register an error handler, pass a closure to the ``error`` method which
+takes an ``Exception`` argument and returns a response::
+
+    use Symfony\Component\HttpFoundation\Response;
+    use Symfony\Component\HttpFoundation\Request;
+
+    $app->error(function (\Exception $e, Request $request, $code) {
+        return new Response('We are sorry, but something went terribly wrong.');
+    });
+
+You can also check for specific errors by using the ``$code`` argument, and
+handle them differently::
+
+    use Symfony\Component\HttpFoundation\Response;
+    use Symfony\Component\HttpFoundation\Request;
+
+    $app->error(function (\Exception $e, Request $request, $code) {
+        switch ($code) {
+            case 404:
+                $message = 'The requested page could not be found.';
+                break;
+            default:
+                $message = 'We are sorry, but something went terribly wrong.';
+        }
+
+        return new Response($message);
+    });
+
+You can restrict an error handler to only handle some Exception classes by
+setting a more specific type hint for the Closure argument::
+
+    use Symfony\Component\HttpFoundation\Request;
+
+    $app->error(function (\LogicException $e, Request $request, $code) {
+        // this handler will only handle \LogicException exceptions
+        // and exceptions that extend \LogicException
+    });
+
+.. note::
+
+    As Silex ensures that the Response status code is set to the most
+    appropriate one depending on the exception, setting the status on the
+    response won't work. If you want to overwrite the status code, set the
+    ``X-Status-Code`` header::
+
+        return new Response('Error', 404 /* ignored */, array('X-Status-Code' => 200));
+
+If you want to use a separate error handler for logging, make sure you register
+it with a higher priority than response error handlers, because once a response
+is returned, the following handlers are ignored.
+
+.. note::
+
+    Silex ships with a provider for Monolog_ which handles logging of errors.
+    Check out the *Providers* :doc:`chapter <providers/monolog>` for details.
+
+.. tip::

+    Silex comes with a default error handler that displays a detailed error
+    message with the stack trace when **debug** is true, and a simple error
+    message otherwise. Error handlers registered via the ``error()`` method
+    always take precedence but you can keep the nice error messages when debug
+    is turned on like this::
+
+        use Symfony\Component\HttpFoundation\Response;
+        use Symfony\Component\HttpFoundation\Request;
+
+        $app->error(function (\Exception $e, Request $request, $code) use ($app) {
+            if ($app['debug']) {
+                return;
+            }
+
+            // ... logic to handle the error and return a Response
+        });
+
+The error handlers are also called when you use ``abort`` to abort a request
+early::
+
+    $app->get('/blog/{id}', function (Silex\Application $app, $id) use ($blogPosts) {
+        if (!isset($blogPosts[$id])) {
+            $app->abort(404, "Post $id does not exist.");
+        }
+
+        return new Response(...);
+    });
+
+You can convert errors to ``Exceptions``, check out the cookbook :doc:`chapter <cookbook/error_handler>` for details.
+
+View Handlers
+-------------
+
+View Handlers allow you to intercept a controller result that is not a
+``Response`` and transform it before it gets returned to the kernel.
+
+To register a view handler, pass a callable (or string that can be resolved to a
+callable) to the ``view()`` method. The callable should accept some sort of result
+from the controller::
+
+    $app->view(function (array $controllerResult) use ($app) {
+        return $app->json($controllerResult);
+    });
+
+View Handlers also receive the ``Request`` as their second argument,
+making them a good candidate for basic content negotiation::
+
+    $app->view(function (array $controllerResult, Request $request) use ($app) {
+        $acceptHeader = $request->headers->get('Accept');
+        $bestFormat = $app['negotiator']->getBestFormat($acceptHeader, array('json', 'xml'));
+
+        if ('json' === $bestFormat) {
+            return new JsonResponse($controllerResult);
+        }
+
+        if ('xml' === $bestFormat) {
+            return $app['serializer.xml']->renderResponse($controllerResult);
+        }
+
+        return $controllerResult;
+    });
+
+View Handlers will be examined in the order they are added to the application
+and Silex will use type hints to determine if a view handler should be used for
+the current result, continuously using the return value of the last view handler
+as the input for the next.
+
+.. note::
+
+    You must ensure that Silex receives a ``Response`` or a string as the result of
+    the last view handler (or controller) to be run.
+
+Redirects
+---------
+
+You can redirect to another page by returning a ``RedirectResponse`` response,
+which you can create by calling the ``redirect`` method::
+
+    $app->get('/', function () use ($app) {
+        return $app->redirect('/hello');
+    });
+
+This will redirect from ``/`` to ``/hello``.
+
+Forwards
+--------
+
+When you want to delegate the rendering to another controller, without a
+round-trip to the browser (as for a redirect), use an internal sub-request::
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpKernel\HttpKernelInterface;
+
+    $app->get('/', function () use ($app) {
+        // forward to /hello
+        $subRequest = Request::create('/hello', 'GET');
+
+        return $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST);
+    });
+
+.. tip::
+
+    You can also generate the URI via the built-in URL generator::
+
+        $request = Request::create($app['url_generator']->generate('hello'), 'GET');
+
+There's some more things that you need to keep in mind though. In most cases you
+will want to forward some parts of the current master request to the sub-request.
+That includes: Cookies, server information, session.
+Read more on :doc:`how to make sub-requests <cookbook/sub_requests>`.
+
+JSON
+----
+
+If you want to return JSON data, you can use the ``json`` helper method.
+Simply pass it your data, status code and headers, and it will create a JSON
+response for you::
+
+    $app->get('/users/{id}', function ($id) use ($app) {
+        $user = getUser($id);
+
+        if (!$user) {
+            $error = array('message' => 'The user was not found.');
+
+            return $app->json($error, 404);
+        }
+
+        return $app->json($user);
+    });
+
+Streaming
+---------
+
+It's possible to stream a response, which is important in cases when you don't
+want to buffer the data being sent::
+
+    $app->get('/images/{file}', function ($file) use ($app) {
+        if (!file_exists(__DIR__.'/images/'.$file)) {
+            return $app->abort(404, 'The image was not found.');
+        }
+
+        $stream = function () use ($file) {
+            readfile($file);
+        };
+
+        return $app->stream($stream, 200, array('Content-Type' => 'image/png'));
+    });
+
+If you need to send chunks, make sure you call ``ob_flush`` and ``flush``
+after every chunk::
+
+    $stream = function () {
+        $fh = fopen('http://www.example.com/', 'rb');
+        while (!feof($fh)) {
+            echo fread($fh, 1024);
+            ob_flush();
+            flush();
+        }
+        fclose($fh);
+    };
+
+Sending a file
+--------------
+
+If you want to return a file, you can use the ``sendFile`` helper method.
+It eases returning files that would otherwise not be publicly available. Simply
+pass it your file path, status code, headers and the content disposition and it
+will create a ``BinaryFileResponse`` response for you::
+
+    $app->get('/files/{path}', function ($path) use ($app) {
+        if (!file_exists('/base/path/' . $path)) {
+            $app->abort(404);
+        }
+
+        return $app->sendFile('/base/path/' . $path);
+    });
+
+To further customize the response before returning it, check the API doc for
+`Symfony\Component\HttpFoundation\BinaryFileResponse
+<http://api.symfony.com/master/Symfony/Component/HttpFoundation/BinaryFileResponse.html>`_::
+
+    return $app
+        ->sendFile('/base/path/' . $path)
+        ->setContentDisposition(ResponseHeaderBag::DISPOSITION_ATTACHMENT, 'pic.jpg')
+    ;
+
+Traits
+------
+
+Silex comes with PHP traits that define shortcut methods.
+
+Almost all built-in service providers have some corresponding PHP traits. To
+use them, define your own Application class and include the traits you want::
+
+    use Silex\Application;
+
+    class MyApplication extends Application
+    {
+        use Application\TwigTrait;
+        use Application\SecurityTrait;
+        use Application\FormTrait;
+        use Application\UrlGeneratorTrait;
+        use Application\SwiftmailerTrait;
+        use Application\MonologTrait;
+        use Application\TranslationTrait;
+    }
+
+You can also define your own Route class and use some traits::
+
+    use Silex\Route;
+
+    class MyRoute extends Route
+    {
+        use Route\SecurityTrait;
+    }
+
+To use your newly defined route, override the ``$app['route_class']``
+setting::
+
+    $app['route_class'] = 'MyRoute';
+
+Read each provider chapter to learn more about the added methods.
+
+Security
+--------
+
+Make sure to protect your application against attacks.
+
+Escaping
+~~~~~~~~
+
+When outputting any user input, make sure to escape it correctly to prevent
+Cross-Site-Scripting attacks.
+
+* **Escaping HTML**: PHP provides the ``htmlspecialchars`` function for this.
+  Silex provides a shortcut ``escape`` method::
+
+      use Symfony\Component\HttpFoundation\Request;
+
+      $app->get('/name', function (Request $request, Silex\Application $app) {
+          $name = $request->get('name');
+
+          return "You provided the name {$app->escape($name)}.";
+      });
+
+  If you use the Twig template engine, you should use its escaping or even
+  auto-escaping mechanisms. Check out the *Providers* :doc:`chapter <providers/twig>` for details.
+
+* **Escaping JSON**: If you want to provide data in JSON format you should
+  use the Silex ``json`` function::
+
+      use Symfony\Component\HttpFoundation\Request;
+
+      $app->get('/name.json', function (Request $request, Silex\Application $app) {
+          $name = $request->get('name');
+
+          return $app->json(array('name' => $name));
+      });

+Webserver Configuration
+=======================
+
+Apache
+------
+
+If you are using Apache, make sure ``mod_rewrite`` is enabled and use the
+following ``.htaccess`` file:
+
+.. code-block:: apache
+
+    <IfModule mod_rewrite.c>
+        Options -MultiViews
+
+        RewriteEngine On
+        #RewriteBase /path/to/app
+        RewriteCond %{REQUEST_FILENAME} !-d
+        RewriteCond %{REQUEST_FILENAME} !-f
+        RewriteRule ^ index.php [QSA,L]
+    </IfModule>
+
+.. note::
+
+    If your site is not at the webroot level you will have to uncomment the
+    ``RewriteBase`` statement and adjust the path to point to your directory,
+    relative from the webroot.
+
+Alternatively, if you use Apache 2.2.16 or higher, you can use the
+`FallbackResource directive`_ to make your .htaccess even easier:
+
+.. code-block:: apache
+
+    FallbackResource index.php
+
+.. note::
+
+    If your site is not at the webroot level you will have to adjust the path to
+    point to your directory, relative from the webroot.
+
+nginx
+-----
+
+The **minimum configuration** to get your application running under Nginx is:
+
+.. code-block:: nginx
+
+    server {
+        server_name domain.tld www.domain.tld;
+        root /var/www/project/web;
+    
+        location / {
+            # try to serve file directly, fallback to front controller
+            try_files $uri /index.php$is_args$args;
+        }
+    
+        # If you have 2 front controllers for dev|prod use the following line instead
+        # location ~ ^/(index|index_dev)\.php(/|$) {
+        location ~ ^/index\.php(/|$) {
+            # the ubuntu default
+            fastcgi_pass   unix:/var/run/php/phpX.X-fpm.sock;
+            # for running on centos
+            #fastcgi_pass   unix:/var/run/php-fpm/www.sock;
+    
+            fastcgi_split_path_info ^(.+\.php)(/.*)$;
+            include fastcgi_params;
+            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
+            fastcgi_param HTTPS off;
+        
+            # Prevents URIs that include the front controller. This will 404:
+            # http://domain.tld/index.php/some-path
+            # Enable the internal directive to disable URIs like this
+            # internal;
+        }
+
+        #return 404 for all php files as we do have a front controller
+        location ~ \.php$ {
+            return 404;
+        }
+    
+        error_log /var/log/nginx/project_error.log;
+        access_log /var/log/nginx/project_access.log;
+    }
+
+IIS
+---
+
+If you are using the Internet Information Services from Windows, you can use
+this sample ``web.config`` file:
+
+.. code-block:: xml
+
+    <?xml version="1.0"?>
+    <configuration>
+        <system.webServer>
+            <defaultDocument>
+                <files>
+                    <clear />
+                    <add value="index.php" />
+                </files>
+            </defaultDocument>
+            <rewrite>
+                <rules>
+                    <rule name="Silex Front Controller" stopProcessing="true">
+                        <match url="^(.*)$" ignoreCase="false" />
+                        <conditions logicalGrouping="MatchAll">
+                            <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
+                        </conditions>
+                        <action type="Rewrite" url="index.php" appendQueryString="true" />
+                    </rule>
+                </rules>
+            </rewrite>
+        </system.webServer>
+    </configuration>
+
+Lighttpd
+--------
+
+If you are using lighttpd, use this sample ``simple-vhost`` as a starting
+point:
+
+.. code-block:: lighttpd
+
+    server.document-root = "/path/to/app"
+
+    url.rewrite-once = (
+        # configure some static files
+        "^/assets/.+" => "$0",
+        "^/favicon\.ico$" => "$0",
+
+        "^(/[^\?]*)(\?.*)?" => "/index.php$1$2"
+    )
+
+.. _FallbackResource directive: http://www.adayinthelifeof.nl/2012/01/21/apaches-fallbackresource-your-new-htaccess-command/
+
+PHP
+---
+
+PHP ships with a built-in webserver for development. This server allows you to
+run silex without any configuration. However, in order to serve static files,
+you'll have to make sure your front controller returns false in that case::
+
+    // web/index.php
+
+    $filename = __DIR__.preg_replace('#(\?.*)$#', '', $_SERVER['REQUEST_URI']);
+    if (php_sapi_name() === 'cli-server' && is_file($filename)) {
+        return false;
+    }
+
+    $app = require __DIR__.'/../src/app.php';
+    $app->run();
+
+
+Assuming your front controller is at ``web/index.php``, you can start the
+server from the command-line with this command:
+
+.. code-block:: text
+
+    $ php -S localhost:8080 -t web web/index.php
+
+Now the application should be running at ``http://localhost:8080``.
+
+.. note::
+
+    This server is for development only. It is **not** recommended to use it
+    in production.

+/**
+ * A generic ErrorHandler for the PHP engine.
+ *
+ * Provides five bit fields that control how errors are handled:
+ * - thrownErrors: errors thrown as \ErrorException
+ * - loggedErrors: logged errors, when not @-silenced
+ * - scopedErrors: errors thrown or logged with their local context
+ * - tracedErrors: errors logged with their stack trace
+ * - screamedErrors: never @-silenced errors
+ *
+ * Each error level can be logged by a dedicated PSR-3 logger object.
+ * Screaming only applies to logging.
+ * Throwing takes precedence over logging.
+ * Uncaught exceptions are logged as E_ERROR.
+ * E_DEPRECATED and E_USER_DEPRECATED levels never throw.
+ * E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
+ * Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
+ * As errors have a performance cost, repeated errors are all logged, so that the developer
+ * can see them and weight them as more important to fix than others of the same level.

+Symfony Debug Extension for PHP 5
+=================================
+
+This extension publishes several functions to help building powerful debugging tools.
+It is compatible with PHP 5.3, 5.4, 5.5 and 5.6; with ZTS and non-ZTS modes.
+It is not required thus not provided for PHP 7.
+
+symfony_zval_info()
+-------------------
+
+- exposes zval_hash/refcounts, allowing e.g. efficient exploration of arbitrary structures in PHP,
+- does work with references, preventing memory copying.
+
+Its behavior is about the same as:
+
+```php
+<?php
+
+function symfony_zval_info($key, $array, $options = 0)
+{
+
+    // $options is currently not used, but could be in future version.
+
+    if (!array_key_exists($key, $array)) {
+        return null;
+    }
+
+    $info = array(
+        'type' => gettype($array[$key]),
+        'zval_hash' => /* hashed memory address of $array[$key] */,
+        'zval_refcount' => /* internal zval refcount of $array[$key] */,
+        'zval_isref' => /* is_ref status of $array[$key] */,
+    );
+
+    switch ($info['type']) {
+        case 'object':
+            $info += array(
+                'object_class' => get_class($array[$key]),
+                'object_refcount' => /* internal object refcount of $array[$key] */,
+                'object_hash' => spl_object_hash($array[$key]),
+                'object_handle' => /* internal object handle $array[$key] */,
+            );
+            break;
+
+        case 'resource':
+            $info += array(
+                'resource_handle' => (int) $array[$key],
+                'resource_type' => get_resource_type($array[$key]),
+                'resource_refcount' => /* internal resource refcount of $array[$key] */,
+            );
+            break;
+
+        case 'array':
+            $info += array(
+                'array_count' => count($array[$key]),
+            );
+            break;
+
+        case 'string':
+            $info += array(
+                'strlen' => strlen($array[$key]),
+            );
+            break;
+    }
+
+    return $info;
+}
+```
+
+symfony_debug_backtrace()
+-------------------------
+
+This function works like debug_backtrace(), except that it can fetch the full backtrace in case of fatal errors:
+
+```php
+function foo() { fatal(); }
+function bar() { foo(); }
+
+function sd() { var_dump(symfony_debug_backtrace()); }
+
+register_shutdown_function('sd');
+
+bar();
+
+/* Will output
+Fatal error: Call to undefined function fatal() in foo.php on line 42
+array(3) {
+  [0]=>
+  array(2) {
+    ["function"]=>
+    string(2) "sd"
+    ["args"]=>
+    array(0) {
+    }
+  }
+  [1]=>
+  array(4) {
+    ["file"]=>
+    string(7) "foo.php"
+    ["line"]=>
+    int(1)
+    ["function"]=>
+    string(3) "foo"
+    ["args"]=>
+    array(0) {
+    }
+  }
+  [2]=>
+  array(4) {
+    ["file"]=>
+    string(102) "foo.php"
+    ["line"]=>
+    int(2)
+    ["function"]=>
+    string(3) "bar"
+    ["args"]=>
+    array(0) {
+    }
+  }
+}
+*/
+```
+
+Usage
+-----
+
+To enable the extension from source, run:
+
+```
+    phpize
+    ./configure
+    make
+    sudo make install
+```

+CHANGELOG
+=========
+
+3.1.0
+-----
+
+ * Added support for creating `JsonResponse` with a string of JSON data
+
+3.0.0
+-----
+
+ * The precedence of parameters returned from `Request::get()` changed from "GET, PATH, BODY" to "PATH, GET, BODY"
+
+2.8.0
+-----
+
+ * Finding deep items in `ParameterBag::get()` is deprecated since version 2.8 and
+   will be removed in 3.0.
+
+2.6.0
+-----
+
+ * PdoSessionHandler changes
+   - implemented different session locking strategies to prevent loss of data by concurrent access to the same session
+   - [BC BREAK] save session data in a binary column without base64_encode
+   - [BC BREAK] added lifetime column to the session table which allows to have different lifetimes for each session
+   - implemented lazy connections that are only opened when a session is used by either passing a dsn string
+     explicitly or falling back to session.save_path ini setting
+   - added a createTable method that initializes a correctly defined table depending on the database vendor
+
+2.5.0
+-----
+
+ * added `JsonResponse::setEncodingOptions()` & `JsonResponse::getEncodingOptions()` for easier manipulation
+   of the options used while encoding data to JSON format.
+
+2.4.0
+-----
+
+ * added RequestStack
+ * added Request::getEncodings()
+ * added accessors methods to session handlers
+
+2.3.0
+-----
+
+ * added support for ranges of IPs in trusted proxies
+ * `UploadedFile::isValid` now returns false if the file was not uploaded via HTTP (in a non-test mode)
+ * Improved error-handling of `\Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler`
+   to ensure the supplied PDO handler throws Exceptions on error (as the class expects). Added related test cases
+   to verify that Exceptions are properly thrown when the PDO queries fail.
+
+2.2.0
+-----
+
+ * fixed the Request::create() precedence (URI information always take precedence now)
+ * added Request::getTrustedProxies()
+ * deprecated Request::isProxyTrusted()
+ * [BC BREAK] JsonResponse does not turn a top level empty array to an object anymore, use an ArrayObject to enforce objects
+ * added a IpUtils class to check if an IP belongs to a CIDR
+ * added Request::getRealMethod() to get the "real" HTTP method (getMethod() returns the "intended" HTTP method)
+ * disabled _method request parameter support by default (call Request::enableHttpMethodParameterOverride() to
+   enable it, and Request::getHttpMethodParameterOverride() to check if it is supported)
+ * Request::splitHttpAcceptHeader() method is deprecated and will be removed in 2.3
+ * Deprecated Flashbag::count() and \Countable interface, will be removed in 2.3
+
+2.1.0
+-----
+
+ * added Request::getSchemeAndHttpHost() and Request::getUserInfo()
+ * added a fluent interface to the Response class
+ * added Request::isProxyTrusted()
+ * added JsonResponse
+ * added a getTargetUrl method to RedirectResponse
+ * added support for streamed responses
+ * made Response::prepare() method the place to enforce HTTP specification
+ * [BC BREAK] moved management of the locale from the Session class to the Request class
+ * added a generic access to the PHP built-in filter mechanism: ParameterBag::filter()
+ * 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
+ * added ResponseHeaderBag::makeDisposition() (implements RFC 6266)
+ * 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 with`MockFileSessionStorage`
+   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
+   behaviour 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 behaviour 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.

+ * for the same session will wait until the other one finished writing. For this
+ * reason it's best practice to close a session as early as possible to improve
+ * concurrency. PHPs internal files session handler also implements locking.

+ * Attention: Since SQLite does not support row level locks but locks the whole database,
+ * it means only one session can be accessed at a time. Even different sessions would wait
+ * for another to finish. So saving session in SQLite should only be considered for
+ * development or prototypes.
+ *
+ * Session data is a binary string that can contain non-printable characters like the null byte.
+ * For this reason it must be saved in a binary column in the database like BLOB in MySQL.
+ * Saving it in a character column could corrupt the data. You can use createTable()
+ * to initialize a correctly defined table.

+/**
+ * Saves the session, in case it is still open, before sending the response/headers.
+ *
+ * This ensures several things in case the developer did not save the session explicitly:
+ *
+ *  * If a session save handler without locking is used, it ensures the data is available
+ *    on the next request, e.g. after a redirect. PHPs auto-save at script end via
+ *    session_register_shutdown is executed after fastcgi_finish_request. So in this case
+ *    the data could be missing the next request because it might not be saved the moment
+ *    the new request is processed.
+ *  * A locking save handler (e.g. the native 'files') circumvents concurrency problems like
+ *    the one above. But by saving the session before long-running things in the terminate event,
+ *    we ensure the session is not blocked longer than needed.
+ *  * When regenerating the session ID no locking is involved in PHPs session design. See
+ *    https://bugs.php.net/bug.php?id=61470 for a discussion. So in this case, the session must
+ *    be saved anyway before sending the headers with the new session ID. Otherwise session
+ *    data could get lost again for concurrent requests with the new ID. One result could be
+ *    that you get logged out after just logging in.
+ *
+ * This listener should be executed as one of the last listeners, so that previous listeners
+ * can still operate on the open session. This prevents the overhead of restarting it.
+ * Listeners after closing the session can still work with the session as usual because
+ * Symfonys session implementation starts the session on demand. So writing to it after
+ * it is saved will just restart it.

+HttpKernel Component
+====================
+
+The HttpKernel component provides a structured process for converting a Request
+into a Response by making use of the EventDispatcher component. It's flexible
+enough to create a full-stack framework (Symfony), a micro-framework (Silex) or
+an advanced CMS system (Drupal).

+CHANGELOG
+=========
+
+3.2.0
+-----
+
+ * Added support for `bool`, `int`, `float`, `string`, `list` and `map` defaults in XML configurations.
+ * Added support for UTF-8 requirements
+  
+2.8.0
+-----
+
+ * allowed specifying a directory to recursively load all routing configuration files it contains
+ * Added ObjectRouteLoader and ServiceRouteLoader that allow routes to be loaded
+   by calling a method on an object/service.
+ * [DEPRECATION] Deprecated the hardcoded value for the `$referenceType` argument of the `UrlGeneratorInterface::generate` method.
+   Use the constants defined in the `UrlGeneratorInterface` instead.
+
+   Before:
+
+   ```php
+   $router->generate('blog_show', array('slug' => 'my-blog-post'), true);
+   ```
+
+   After:
+
+   ```php
+   use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
+
+   $router->generate('blog_show', array('slug' => 'my-blog-post'), UrlGeneratorInterface::ABSOLUTE_URL);
+   ```
+
+2.5.0
+-----
+
+ * [DEPRECATION] The `ApacheMatcherDumper` and `ApacheUrlMatcher` were deprecated and
+   will be removed in Symfony 3.0, since the performance gains were minimal and
+   it's hard to replicate the behaviour of PHP implementation.
+
+2.3.0
+-----
+
+ * added RequestContext::getQueryString()
+
+2.2.0
+-----
+
+ * [DEPRECATION] Several route settings have been renamed (the old ones will be removed in 3.0):
+
+    * The `pattern` setting for a route has been deprecated in favor of `path`
+    * The `_scheme` and `_method` requirements have been moved to the `schemes` and `methods` settings
+
+   Before:
+
+   ```yaml
+   article_edit:
+       pattern: /article/{id}
+       requirements: { '_method': 'POST|PUT', '_scheme': 'https', 'id': '\d+' }
+   ```
+
+   ```xml
+   <route id="article_edit" pattern="/article/{id}">
+       <requirement key="_method">POST|PUT</requirement>
+       <requirement key="_scheme">https</requirement>
+       <requirement key="id">\d+</requirement>
+   </route>
+   ```
+
+   ```php
+   $route = new Route();
+   $route->setPattern('/article/{id}');
+   $route->setRequirement('_method', 'POST|PUT');
+   $route->setRequirement('_scheme', 'https');
+   ```
+
+   After:
+
+   ```yaml
+   article_edit:
+       path: /article/{id}
+       methods: [POST, PUT]
+       schemes: https
+       requirements: { 'id': '\d+' }
+   ```
+
+   ```xml
+   <route id="article_edit" pattern="/article/{id}" methods="POST PUT" schemes="https">
+       <requirement key="id">\d+</requirement>
+   </route>
+   ```
+
+   ```php
+   $route = new Route();
+   $route->setPath('/article/{id}');
+   $route->setMethods(array('POST', 'PUT'));
+   $route->setSchemes('https');
+   ```
+
+ * [BC BREAK] RouteCollection does not behave like a tree structure anymore but as
+   a flat array of Routes. So when using PHP to build the RouteCollection, you must
+   make sure to add routes to the sub-collection before adding it to the parent
+   collection (this is not relevant when using YAML or XML for Route definitions).
+
+   Before:
+
+   ```php
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $rootCollection->addCollection($subCollection);
+   $subCollection->add('foo', new Route('/foo'));
+   ```
+
+   After:
+
+   ```php
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $subCollection->add('foo', new Route('/foo'));
+   $rootCollection->addCollection($subCollection);
+   ```
+
+   Also one must call `addCollection` from the bottom to the top hierarchy.
+   So the correct sequence is the following (and not the reverse):
+
+   ```php
+   $childCollection->addCollection($grandchildCollection);
+   $rootCollection->addCollection($childCollection);
+   ```
+
+ * [DEPRECATION] The methods `RouteCollection::getParent()` and `RouteCollection::getRoot()`
+   have been deprecated and will be removed in Symfony 2.3.
+ * [BC BREAK] Misusing the `RouteCollection::addPrefix` method to add defaults, requirements
+   or options without adding a prefix is not supported anymore. So if you called `addPrefix`
+   with an empty prefix or `/` only (both have no relevance), like
+   `addPrefix('', $defaultsArray, $requirementsArray, $optionsArray)`
+   you need to use the new dedicated methods `addDefaults($defaultsArray)`,
+   `addRequirements($requirementsArray)` or `addOptions($optionsArray)` instead.
+ * [DEPRECATION] The `$options` parameter to `RouteCollection::addPrefix()` has been deprecated
+   because adding options has nothing to do with adding a path prefix. If you want to add options
+   to all child routes of a RouteCollection, you can use `addOptions()`.
+ * [DEPRECATION] The method `RouteCollection::getPrefix()` has been deprecated
+   because it suggested that all routes in the collection would have this prefix, which is
+   not necessarily true. On top of that, since there is no tree structure anymore, this method
+   is also useless. Don't worry about performance, prefix optimization for matching is still done
+   in the dumper, which was also improved in 2.2.0 to find even more grouping possibilities.
+ * [DEPRECATION] `RouteCollection::addCollection(RouteCollection $collection)` should now only be
+   used with a single parameter. The other params `$prefix`, `$default`, `$requirements` and `$options`
+   will still work, but have been deprecated. The `addPrefix` method should be used for this
+   use-case instead.
+   Before: `$parentCollection->addCollection($collection, '/prefix', array(...), array(...))`
+   After:
+   ```php
+   $collection->addPrefix('/prefix', array(...), array(...));
+   $parentCollection->addCollection($collection);
+   ```
+ * added support for the method default argument values when defining a @Route
+ * Adjacent placeholders without separator work now, e.g. `/{x}{y}{z}.{_format}`.
+ * Characters that function as separator between placeholders are now whitelisted
+   to fix routes with normal text around a variable, e.g. `/prefix{var}suffix`.
+ * [BC BREAK] The default requirement of a variable has been changed slightly.
+   Previously it disallowed the previous and the next char around a variable. Now
+   it disallows the slash (`/`) and the next char. Using the previous char added
+   no value and was problematic because the route `/index.{_format}` would be
+   matched by `/index.ht/ml`.
+ * The default requirement now uses possessive quantifiers when possible which
+   improves matching performance by up to 20% because it prevents backtracking
+   when it's not needed.
+ * The ConfigurableRequirementsInterface can now also be used to disable the requirements
+   check on URL generation completely by calling `setStrictRequirements(null)`. It
+   improves performance in production environment as you should know that params always
+   pass the requirements (otherwise it would break your link anyway).
+ * There is no restriction on the route name anymore. So non-alphanumeric characters
+   are now also allowed.
+ * [BC BREAK] `RouteCompilerInterface::compile(Route $route)` was made static
+   (only relevant if you implemented your own RouteCompiler).
+ * Added possibility to generate relative paths and network paths in the UrlGenerator, e.g.
+   "../parent-file" and "//example.com/dir/file". The third parameter in
+   `UrlGeneratorInterface::generate($name, $parameters = array(), $referenceType = self::ABSOLUTE_PATH)`
+   now accepts more values and you should use the constants defined in `UrlGeneratorInterface` for
+   claritiy. The old method calls with a Boolean parameter will continue to work because they
+   equal the signature using the constants.
+
+2.1.0
+-----
+
+ * added RequestMatcherInterface
+ * added RequestContext::fromRequest()
+ * the UrlMatcher does not throw a \LogicException anymore when the required
+   scheme is not the current one
+ * added TraceableUrlMatcher
+ * added the possibility to define options, default values and requirements
+   for placeholders in prefix, including imported routes
+ * added RouterInterface::getRouteCollection
+ * [BC BREAK] the UrlMatcher urldecodes the route parameters only once, they
+   were decoded twice before. Note that the `urldecode()` calls have been
+   changed for a single `rawurldecode()` in order to support `+` for input
+   paths.
+ * added RouteCollection::getRoot method to retrieve the root of a
+   RouteCollection tree
+ * [BC BREAK] made RouteCollection::setParent private which could not have
+   been used anyway without creating inconsistencies
+ * [BC BREAK] RouteCollection::remove also removes a route from parent
+   collections (not only from its children)
+ * added ConfigurableRequirementsInterface that allows to disable exceptions
+   (and generate empty URLs instead) when generating a route with an invalid
+   parameter value

+ *   production environment. It should log the mismatch so one can review it.
+ * - setStrictRequirements(null): Return the URL with the given parameters without
+ *   checking the requirements at all. When generating a URL you should either trust
+ *   your params or you validated them beforehand because otherwise it would break your
+ *   link anyway. So in production environment you should know that params always pass
+ *   the requirements. Thus this option allows to disable the check on URL generation for

+ * You need to define an implementation for the getRouteDefaults() method. Most of the

+ *
+ * The @Route annotation can be set on the class (for global parameters),
+ * and on each method.

+ * The @Route annotation main value is the route path. The annotation also
+ * recognizes several parameters: requirements, options, defaults, schemes,
