[PATCH] wayland-serer: Remove input structs and helper functions

Kristian Høgsberg krh at bitplanet.net
Mon Apr 29 14:23:03 PDT 2013


Looking at the functionality in the server library, it's clear (in hindsight)
that there are two different "things" in there: 1) The IPC API, that is,
everything that concerns wl_display, wl_client, wl_resource and
2) a half-hearted attempt at sharing input code and focus logic that
leaves a lot of problematic structs in the API surface, only to share
less than 1000 lines of code.

We can move those input structs and helper functions into weston and
cut libwayland-server down to just the core server side IPC API.
In the short term, compositors can copy those structs and functions
into their source, but longer term, they're probably better off
reimplementing those objects and logic directly in their native object
framework (QObject, GObject etc).
