tests: test if thread can block on error
wl_display_read_events() can make a thread wait until some other thread
ends reading. Normally it wakes up all threads after the reading is
done. But there's a place when it does not get to waking up the threads
- when an error occurs. This test reveals bug that can block programs.
If a thread is waiting in wl_display_read_events() and another thread
calls wl_display_read_events and the reading fails,
then the sleeping thread is not woken up. This is because
display_handle_error is using old pthread_cond instead of new
display->reader_cond, that was added along with wl_display_read_events().

tests: add test-compositor
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);
}

server: Don't expose wl_display as a global
The idea here was that once upon a time, clients could rebind wl_display
to a higher version, so we offered the ability to rebind it
here. However, this is particularly broken. The existing bind
implementation actually still hardcodes version numbers, and it leaks
previous resources, overwriting the existing one.
The newly bound resource *also* won't have any listeners attached by the
client, meaning that the error and delete_id events won't get delivered
correctly. Unless the client poked into libwayland internals, it also
can't possibly set up these handlers correctly either, so the client
will sustain errors and leak all deleted globals.
Since this never worked correctly in the first place, we can feel safe
removing it.

Do not distribute generated headers
The wayland-server-protocol.h and wayland-client-protocol.h headers are
currently being shipped in tarballs created using make dist. This causes
out-of-tree builds to fail since make will detect that the headers exist
by looking at the source directory (via VPATH) and not regenerate them.
But as opposed to ${top_builddir}/protocol, ${top_srcdir}/protocol is
not part of the include path and therefore the shipped files can't be
found during compilation.
Two solutions exist to this problem: 1) add ${top_srcdir}/protocol to
the include path to allow shipped files to be used if available or 2)
don't ship these generated files in release tarballs. The latter seems
the most appropriate. wayland-scanner is already a prerequisite in order
to generate wayland-protocol.c, so it is either built as part of the
package or provided externally. Generating all files from the protocol
definition at build time also ensures that they don't get out of sync.
Both of the generated headers are already listed in Makefile.am as
nodist_*_SOURCES, but at the same time they appear in include_HEADERS,
which will cause them to be added to the list of distributable files
after all. To prevent that, split them off into nodist_include_HEADERS.
Note that this problem will be hidden if a previous version of wayland
has been installed, since these files will exist in /usr/include and be
included from there. So this build error will only show for out-of-tree
builds on systems that don't have wayland installed yet.

with EAGAIN. We still report all other errors as before, and still ignore the
actual value read from the socket.
With this change, the event_loop_timer_updates unit test case I submitted
previously now passes, and weston appears to work as before.

test: Add test showing blocking problem when updating timers
I've noticed a blocking problem in Wayland's event-loop code when updating
timer event sources. The problem occurs if you update the timer at a point
after is has expired, but before it has been dispatched, i.e. from an event
callback that happens during the same epoll wakeup.
When the timer is subsequently dispatched, wl_event_source_timer_dispatch
blocks for the duration of the new timeout in its call to read() from the
timer fd (which is the expected behaviour according to the man page for
timerfd_settime).
This isn't too uncommon a scenario - for example, a socket with an associated
timeout timer. You'd typically want to update the timer when reading from the
socket. This is how I noticed the issue, since I was setting a timeout of
1 minute, and saw my server blocking for this duration!
The following patch adds a (currently failing) test case to Wayland's
event-loop-test.c. It demonstrates the problem using two timers, which are
set to expire at the same time. The first timer to receive its expiry
callback updates the other timer with a much larger timeout, which then
causes the test to block for this timeout before calling the second timer's
callback.
As for a fix, I'm not so sure (which is why I thought I'd post the failing
test case first to show what I mean). I notice that it doesn't actually do
anything with the value read from the timerfd socket, which gives the number
of times the timer expired since the last read, or when the timer was last
updated (which blocks if the timer hasn't yet expired). I believe this value
should always read as 1 anyway, since we don't use periodic timers.
A simple fix would be to use the TFD_NONBLOCK option when creating the
timerfd, ensuring that the read call won't block. We'd then have to ignore
the case when the read returns EAGAIN.

protocol: try to clarify frame callback semantics
"the callback event will arrive after the next output refresh" is wrong,
if you interpret "output refresh" as framebuffer flip or the moment when
the new pixels turn into light the first time. Weston has probably never
worked this way.
Weston triggers the frame callbacks when it submits repainting commands
to the GPU, which is before the framebuffer flip.
Strike the incorrect claim, and the rest of the paragraph which no
longer offers useful information.
As a replacement, expand on the "throttling and driving animations"
characteristic. The main purpose is to let clients animate at the
display refresh rate, while avoiding drawing frames that will never be
presented.
The new claim is that the server should give some time between
triggering frame callbacks and repainting itself, for clients to draw
and commit. This is somewhat intimate with the repaint scheduling
algorithm a compositor uses, but hopefully the right intention.
Another point of this update is to imply, that frame callbacks should
not be used to count compositor repaint cycles nor monitor refresh
cycles. It has never been guaranteed to work. Removing the mention of
frame callback without an attach hopefully discourages such use.
v2: Don't just remove a paragraph, but add useful information about the
request's intent.
v3: Specify the order of posting frame callbacks.

Don't deref the sample pointer in the wl_container_of macro
The previous implementation of the wl_container_of macro was
dereferencing the sample pointer in order to get an address of the
member to calculate the offset. Ideally this shouldn't cause any
problems because the dereference doesn't actually cause the address to
be read from so it shouldn't matter if the pointer is uninitialised.
However this is probably technically invalid and could cause undefined
behavior. Clang appears to take advantage of this undefined behavior
and doesn't bother doing the subtraction. It also gives a warning when
it does this.
The documentation for wl_container_of implies that it should only be
given an initialised pointer and if that is done then there is no
problem with clang. However this is quite easy to forget and doesn't
cause any problems or warnings with gcc so it's quite easy to
accidentally break clang.
To fix the problem this changes the macro to use pointer -
offsetof(__typeof__(sample), member) so that it doesn't need to deref
the sample pointer. This does however require that the __typeof__
operator is supported by the compiler. In practice we probably only
care about gcc and clang and both of these happily support the
operator.
The previous implementation was also using __typeof__ but it had a
fallback path avoiding it when the operator isn't available. The
fallback effectively has undefined behaviour and it is targetting
unknown compilers so it is probably not a good idea to leave it in.
Instead, this patch just removes it. If someone finds a compiler that
doesn't have __typeof__ but does work with the old implementation then
maybe they could add it back in as a special case.
This patch removes the initialisation anywhere where the sample
pointer was being unitialised before using wl_container_of. The
documentation for the macro has also been updated to specify that this
is OK.
