With the more accurate definition of wl_surface roles in Wayland, enforce the restriction: a role is always set permanently, and attempting to change it is a protocol error. This patch is based on Jasper's patch: http://lists.freedesktop.org/archives/wayland-devel/2014-August/016811.html The difference in this patch compared to his are: - send role errors on the interface whose request triggers it, not on wl_surface - an interface could have several requests assigning different roles, cannot use wl_interface as the unique key; use an arbitary string instead - ensure in window-manager.c that create_shell_surface() -> create_common_surface() is never called with surface->configure set, to avoid compositor abort - use wl_resource_post_no_memory() where appropriate instead of hand-rolling it with wl_resource_post_error() Ideally we would not add weston_surface::role_name field, but use weston_surface::configure. At the moment this is not possible though, because at least shell.c uses several different roles with the same configure function. Drag'n'drop uses two configure functions for the same role. The configure hook is also reset in several places, which is not good for role tracking. This patch overlooks the wl_surface roles assigned in privileged extensions: screensaver, panel, background, lock, input panel.

Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for building weston and its dependencies. The test suite can be invoked via `make check`; see http://wayland.freedesktop.org/testing.html for additional details.
