The document discusses how Symfony2 components are being incorporated into Drupal 8 to help transform it into a first-class REST server. The key components being utilized are the HTTP Kernel, which provides a structured process for converting requests to responses using events, the HTTP Foundation, which defines an object-oriented layer for the HTTP specification, and the Event Dispatcher, which enables a plugin system and allows components to utilize both hooks and events. These components provide Drupal with more flexibility and capabilities as a REST platform.

Web Services and Context Core Initiative The Web Services and Context Core Initiative (WSCCI) aims to transform Drupal from a first-class CMS to a first-class REST server with a first-class CMS on top of it. To do that, we must give Drupal a unified, powerful context system that will support smarter, context- sensitive, easily cacheable block-centric layouts and non-page responses using a robust unified plugin mechanism.

- 20. Symfony2 A reusable set of standalone, decoupled, and cohesive PHP components that solve common web development problems. “An HTTP framework; it is a Request / Response framework. That's the big deal. The fundamental principles of Symfony2 are centered around the HTTP specification.” ~ Fabien Potencier

- 24. HTTP Kernel Component The HttpKernel Component provides a structured process for converting a Request into a Response by making use of the event dispatcher.
- 26. HTTP Kernel Component The HttpKernel Component provides a structured process for converting a Request into a Response by making use of the event dispatcher. Flexible enough to create: ● a full-stack framework (Symfony) ● a micro-framework (Silex) ● an advanced CMS system (Drupal)

- 29. HTTP Foundation Component The HttpFoundation Component defines an object-oriented layer for the HTTP specification.
- 30. HTTP Foundation Component It is an Object-Oriented abstraction of some native PHP functions and variables:
- 31. HTTP Foundation Component It is an Object-Oriented abstraction of some native PHP functions and variables: The Request class abstracts the main PHP global variables like: ● $_GET ● $_POST ● $_COOKIE ● $_FILES ● $_SERVER
- 32. HTTP Foundation Component It is an Object-Oriented abstraction of some native PHP functions and variables: The Response class abstracts some PHP functions like ● Header() ● Setcookie() ● echo
- 33. HTTP Foundation Component It is an Object-Oriented abstraction of some native PHP functions and variables: The Session class and SessionStorageInterface interface abstract session management session_*() functions.
- 34. Symfony2 Components ● Http Kernel ● Http Foundation ● Event Dispatcher
- 36. Event Dispatcher Component ● A listener (PHP object) tells a central dispatcher object that it wants to listen to an event;
- 37. Event Dispatcher Component ● A listener (PHP object) tells a central dispatcher object that it wants to listen to an event; ● At some point, the dispatcher object is told to dispatch the event, passing with it an Event object;
- 38. Event Dispatcher Component ● A listener (PHP object) tells a central dispatcher object that it wants to listen to an event; ● At some point, the dispatcher object is told to dispatch the event, passing with it an Event object; ● The dispatcher notifies (i.e. calls a method on) all listeners of the dispatched event, allowing each of them to make modifications to the Event object.
- 40. Event Dispatcher Component ● Enable a system-wide plugin system ● Drupal 8 will run hook system and Event Dispatcher in parallel and power a lot of the core-level Drupal components. ● Drupal 9 – its up for discussion! “The D8 cycle will allow us to gain some experience with event subscribers, and compare them with hooks.” ● EventDispatcher more flexible (inheritance) & dependencies can be injected via the DIC. http://drupal.org/node/1509164

- 45. Routing Component The Routing Component maps an HTTP request to a set of configuration variables. ● Define routes – YAML – XML – PHP
- 47. HTTP Kernel Component kernel.request event ● Add more information to the Request, ● Initialize parts of the system ● Router listener ● Return a Response (denied!!!)
- 50. HTTP Kernel Component Resolve the controller based on routing info. ● ControllerResolver ● getController() ● getArguments()
- 52. HTTP Kernel Component kernel.controller event ● Initialize things for your app ● Change the controller
- 54. HTTP Kernel Component HttpKernel::handle() ● Executes the controller ● Passes it arguments ● Controller builds response (resource)
- 58. HTTP Kernel Component kernel.view event Transform a non-Response return value from a controller into a Response. ● Array to JSON ● Array to HTML ● Whatever you want to Whatever you want
- 60. HTTP Kernel Component kernel.response event ● Modify Response before it's sent ● HTTP Headers ● Add cookies ● Change the response itself
