Wayland (Display Server와 Client 사이 통신 프로토콜)

01 Wayland란

1. 정의

• a communication protocol that specifies the communication b/w a Display Server and its clients, as well as a C library implementation of that protocol
• 즉 Display Server와 Client가 통신할 수 있게 하는 프로토콜, 데스크탑 환경을 구현하기 위한 프로토콜 (C 언어 사용)
• a Display Server using the Wayland protocol is called a Wayland compositor, b/c it additionally performs the task of a compositing Window Manager (WM)
• the language (protocol) that applications can use to talk to a Display Server in order to make themselves visible and get input from the user (a person)
  • A Wayland server is called a "compositor"
    
  • Applications are Wayland clients
• Wayland also refers to a system architecture. 
  • It is not just a server-client relationship b/w a compositor and applications.
  • There is no single common Wayland server like Xorg is for X11, but every graphical environment brings with it one of many compositor implementations.
  • Window management and the end user experience are often tied to the compositor rather than swappable components.
• A core part of Wayland architecture is libwayland
  • libwayland: an inter-process communication library that translates a protocol definition in XML to a C language API
  • This library does not implement Wayland, it merely encodes and decodes Wayland messages.
  • The actual implementations are in the various compositor and application toolkit projects.
