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.

client: Introduce functions to allocate and marshal proxies atomically
The server requires clients to only allocate one ID ahead of the previously
highest ID in order to keep the ID range tight. Failure to do so will
make the server close the client connection. However, the way we allocate
new IDs is racy. The generated code looks like:
new_proxy = wl_proxy_create(...);
wl_proxy_marshal(proxy, ... new_proxy, ...);
If two threads do this at the same time, there's a chance that thread A
will allocate a proxy, then get pre-empted by thread B which then allocates
a proxy and then passes it to wl_proxy_marshal(). The ID for thread As
proxy will be one higher that the currently highest ID, but the ID for
thread Bs proxy will be two higher. But since thread B prempted thread A
before it could send its new ID, B will send its new ID first, the server
will see the ID from thread Bs proxy first, and will reject it.
We fix this by introducing wl_proxy_marshal_constructor(). This
function is identical to wl_proxy_marshal(), except that it will
allocate a wl_proxy for NEW_ID arguments and send it, all under the
display mutex. By introducing a new function, we maintain backwards
compatibility with older code from the generator, and make sure that
the new generated code has an explicit dependency on a new enough

there.
Sub-surface is a wl_surface role. You create a wl_surface as usual, and
assign it the sub-surface role and a parent wl_surface. Sub-surfaces are
an integral part of the parent surface, and stay glued to the parent.
For window management, a window is the union of the top-level
wl_surface and all its sub-surfaces. Sub-surfaces are not clipped to the
parent, and the union of the surface tree can be larger than the
(top-level) wl_surface at its root.
The representative use case for sub-surfaces is a video player window.
When the video content is given its own wl_surface, there is no need to
modify the video frame contents after decoding or copy them into a whole
window sized buffer before submitting it to the compositor. This allows
efficient, zero-copy video presentation paths, where video decoding
hardware produces a (YUV) buffer, which eventually ends up in a
(YUV-capable) hardware overlay and is scanned out directly.
This can also be used for zero-copy presentation of windowed OpenGL
content, where the OpenGL rendering engine does not need to draw or
avoid window decorations.
Sub-surfaces allow mixing different buffer types into the same window,
e.g. software-rendered decorations in wl_shm buffers, and live content
in EGL-based buffers.
However, the sub-surface extension does not offer clipping or scaling
facilities, or accurate presentation timing. Those are topics for
additional extensions.

server: Add API to protect access to an SHM buffer
Linux will let you mmap a region of a file that is larger than the
size of the file. If you then try to read from that region the process
will get a SIGBUS signal. Currently the clients can use this to crash
a compositor because it can create a pool and lie about the size of
the file which will cause the compositor to try and read past the end
of it. The compositor can't simply check the size of the file to
verify that it is big enough because then there is a race condition
where the client may truncate the file after the check is performed.
This patch adds the following two public functions in the server API
which can be used wrap access to an SHM buffer:
void wl_shm_buffer_begin_access(struct wl_shm_buffer *buffer);
void wl_shm_buffer_end_access(struct wl_shm_buffer *buffer);
The first time wl_shm_buffer_begin_access is called a signal handler
for SIGBUS will be installed. If the signal is caught then the buffer
for the current pool is remapped to an anonymous private buffer at the
same address which allows the compositor to continue without crashing.
The end_access function will then post an error to the buffer
resource.
The current pool is stored as part of some thread-local storage so
that multiple threads can safely independently access separate
buffers.
Eventually we may want to add some more API so that compositors can
hook into the signal handler or replace it entirely if they also want
to do some SIGBUS handling.

client: Fix handling display->reader_count if poll fails
In wl_display_dispatch_queue, if poll fails then it would previously
return immediately and leak a reference in display->reader_count. Then
if the application ignores the error and tries to read again it will
block forever. This can happen for example if the poll fails with
EINTR which the application might consider to be a recoverable error.
This patch makes it cancel the read so the reader_count will be
decremented when poll fails.
