Abstract the backend interface away

Remove the fixed calls into the udev backend and provide a basic interface
instead that allows other backends to hook into device/seat creation. This
enables multiple backends, specifically a path-based backend that is needed
for X.Org drivers.

10 years agoPort udev-seat to be used in libinput
Jonas Ådahl [Sat, 23 Nov 2013 12:04:32 +0000 (13:04 +0100)]
Port udev-seat to be used in libinput

This patch ports udev-seat from weston to libinput, including adapting
libinput internals and API to provide seat and device discovery.

The public API is extended with device discovery, object reference, a
seat object. As libinput takes care of creating and destroying its
objects user data getter/setter is added in order to make it possible
for the client to directly associate an object application side with an
object library side.

Device discovery API is made up of the 'seat added', 'seat removed',
'device added' and 'device removed' events. The seat added/removed
events contains a pointer to a libinput_seat struct, while the device
added/removed events contains a pointer to a libinput_device event.

The objects are reference counted with libinput holding one reference by
default. The application can increase the reference count with
libinput_seat_ref() and libinput_device_ref() and decrease the reference
count with libinput_seat_unref() and libinput_device_unref().

The basic event struct is changed to have a 'target' union parameter
that can be either a libinput, libinput_seat or libinput_device struct
pointer.

There is one known problem with the current API that is the potentially
racy initialization.

The problem is when a device is both discovered and lost during initial
dispatchig, causing libinput to first queue a 'added' message, creating
the device with default reference count 1, then before going back to the
application queuing a 'removed' message, while at same time decreasing
reference count of the device to 0, causing it o be destroyed. The queue
will at this state contain two messages with pointers to free:ed memory.

Introduce libinput object managing all input data

Instead of having the user manage added and removed fd's as well as the
fd used for creating evdev devices, introduce a libinput object that
itself has an epoll fd.

The user no longer manages multiple fd's per libinput instance, but
instead handles one fd, dispatches libinput when data is available, then
reading events using libinput_get_event().

libinput_event's are now per libinstance, but divided into categories.
So far the only category is device events. Device events are categorized
by the presence of a non-NULL device pointer in the event.

The current API usage should look like:

struct libinput libinput = ...;
struct libinput_event *event;

if (libinput_dispatch(libinput) != 0)
return -1;
while ((event = libinput_get_event(libinput))) {
