This patch introduces a set of functions that can create a display
and clients for tests.
On server side the user can use functions:
display_create()
display_destroy()
create_client()
display_run()
display_resume()
and on client side the user can use:
client_connect()
client_disconnect()
stop_display()
The stop_display() and display_resume() are functions that serve as a barrier
and also allow the display to take some action after the display_run() was called,
because after the display is stopped, it can run arbitrary code until it calls
display_resume().
client_connect() function connects to wayland display and creates a proxy to
test_compositor global object, so it can ask for stopping the display later
using stop_display().
An example:
void
client_main()
{
/* or client can use wl_display_connect(NULL)
* and do all the stuff manually */
struct client *c = client_connect();
/* do some stuff, ... */
/* stop the display so that it can
* do some other stuff */
stop_display(c, 1);
/* ... */
client_disconnect(c);
}
TEST(dummy_tst)
{
struct display *d = display_create();
/* set up the display */
wl_global_create(d->wl_display, ...);
/* ... */
create_client(d, client_main);
display_run();
/* if we are here, the display has been stopped
* and we can do some code, i. e. create another global or so */
wl_global_create(d->wl_display, ...);
/* ... */
display_resume(d); /* resume display and clients */
display_destroy(d);
}
v2:
added/changed message in few asserts that were not clear
fixed codying style issues and typo
client_create_with_name: fixed a condition in an assert
get_socket_name: use also pid
check_error: fix errno -> err
[Pekka Paalanen: added test-compositor.h to SOURCES, added
WL_HIDE_DEPRECATED to get rid of deprecated defs and lots of warnings,
fixed one unchecked return value from write().]

What is Wayland
Wayland is a project to define a protocol for a compositor to talk to
its clients as well as a library implementation of the protocol. The
compositor can be a standalone display server running on Linux kernel
modesetting and evdev input devices, an X application, or a wayland
client itself. The clients can be traditional applications, X servers
(rootless or fullscreen) or other display servers.
The wayland protocol is essentially only about input handling and
buffer management. The compositor receives input events and forwards
them to the relevant client. The clients creates buffers and renders
into them and notifies the compositor when it needs to redraw. The
protocol also handles drag and drop, selections, window management and
other interactions that must go through the compositor. However, the
protocol does not handle rendering, which is one of the features that
makes wayland so simple. All clients are expected to handle rendering
themselves, typically through cairo or OpenGL.
The weston compositor is a reference implementation of a wayland
compositor and the weston repository also includes a few example
clients.
Building the wayland libraries is fairly simple, aside from libffi,
they don't have many dependencies:
$ git clone git://anongit.freedesktop.org/wayland/wayland
$ cd wayland
$ ./autogen.sh --prefix=PREFIX
$ make
$ make install
where PREFIX is where you want to install the libraries. See
http://wayland.freedesktop.org for more complete build instructions
for wayland, weston, xwayland and various toolkits.
