shell-utils contains a number of helpers which are currently in use by
both desktop-shell and kiosk-shell. In order to extend this use to
fullscreen-shell as well (which can benefit from reusing the
weston_curtain infrastructure to be able to create solid-colour views
which may or may not be opaque, as well as one function within
fullscreen-shell which was copied wholesale to shell-utils), we need to
create a separate Meson dependency object, and avoid the existing
pattern of including the source from shared/ within the source list for
each shell.
This requires creating a new top-level directory for these shared helper
functions which are required by each shell, but are not part of
libweston in and of itself.
shell-utils depends on libweston-desktop; libweston-desktop depends on
libweston; libweston depends on shared.
Thus it is not possible to expose a dependency object from the shared/
directory which declares a dependency on the libweston-desktop
dependency, as Meson processes directories in order and resolves
variable references as they are parsed.
In order to break this deadlock, this commit creates a new top-level
directory called 'shell-utils' containing only this file, which can be
parsed by Meson after libweston-desktop (making the libweston-desktop
Meson dependency variable available to the build file to declare a
dependency on that), but before the shells (making the new Meson
depenendency object available to each shell which wishes to use it).
This commit contains no functional changes to any observable code.

This is a new function exporting macro that intends to make writing unit
tests in the Weston test suite easier.
A test needs to access a private function to be able to verify its
behavior. Previously we have used things like putting such functions in
a separate .c file and then building that file into the corresponding
test. That is a bit awkward and can lead to proliferation of arbitrary
.c files for no good reason. It may also require pre-processor magic,
and sometimes copying chunks of code causing a risk of deviating the
code being tested from the code actually used.
This patch proposes another approach: a private export from a DSO.
Except, private exports do not really exist, and this is just a normal
export with a specific C macro, and omitting the function from public
headers.
Once exported, a test program can link the DSO during build, be that a
shared library or even a plugin, use the private header declaring the
function, and simply call the function in the test.
The declaration of WESTON_EXPORT_FOR_TESTS is in shared/helpers.h so
that it is available to all components equally while still not being in
a public header. Other places that were considered:
- include/libweston/libweston.h is a public header, but external users
should not know about the macro.
- libweston/libweston-private.h is too private and not available to all
components, particularly color-lcms plugin.
- libweston/backend.h is not appropriate for color-lcms plugin either.

These formats are useful because they are often easier to produce

Wayland signals (wl_signal) do not reliably handle changes to the
notification list during signal emission. Such scenarios occasionally
come up and can be difficult to investigate and debug.
This commit introduces the weston_signal_emit_mutable() function which can be
used in place of wl_signal_emit() and safely implements the following
behavior regarding notification list changes:
1. Listeners deleted during a signal emission and which have not already been
notified at the time of deletion are not notified by that emission.
2. Listeners added during signal emission are ignored by that emission.
The implementation of weston_signal_emit_mutable() is copied from the
wlr_signal_emit_safe() function of the wlroots project.

The ro_anonymous_file is an abstraction around anonymous read-only files.
os_ro_anonymous_file_create creates such a file with the contents passed
in data. Subsequent calls to os_ro_anonymous_file_get_fd return a fd
that's ready to be send over the socket.
When mapmode is RO_ANONYMOUS_FILE_MAPMODE_PRIVATE the fd is only
guaranteed to be mmap-able readonly with MAP_PRIVATE but does not
require duplicating the file for each resource when memfd_create is
available. RO_ANONYMOUS_FILE_MAPMODE_SHARED may be used when the client
must be able to map the file with MAP_SHARED but it also means that the
file has to be duplicated even when memfd_create is available.

Implement the set_acquire_fence request of the
zwp_surface_synchronization_v1 interface.
The implementation uses the acquire fence in two ways:
1. If the associated buffer is used as GL render source, an
EGLSyncKHR is created from the fence and used to synchronize
access.
2. If the associated buffer is used as a plane framebuffer,
the acquire fence is treated as an in-fence for the atomic
commit operation. If in-fences are not supported and the buffer
has an acquire fence, we don't consider it for plane placement.
If the used compositor/renderer doesn't support explicit
synchronization, we don't advertise the protocol at all. Currently only
the DRM and X11 backends when using the GL renderer advertise the
protocol for production use.
Issues for discussion
---------------------
a. Currently, a server-side wait of EGLSyncKHR is performed before
using the EGLImage/texture during rendering. Unfortunately, it's not clear
from the specs whether this is generally safe to do, or we need to
sync before glEGLImageTargetTexture2DOES. The exception is
TEXTURE_EXTERNAL_OES where the spec mentions it's enough to sync
and then glBindTexture for any changes to take effect.
Changes in v5:
- Meson support.
- Make explicit sync server error reporting more generic, supporting
all explicit sync related interfaces not just
wp_linux_surface_synchronization.
- Fix typo in warning for missing EGL_KHR_wait_sync extension.
- Support minor version 2 of the explicit sync protocol (i.e., support
fences for opaque EGL buffers).
Changes in v4:
- Introduce and use fd_clear and and fd_move helpers.
- Don't check for a valid buffer when updating surface acquire fence fd
from state.
- Assert that pending state acquire fence fd is always clear
after a commit.
- Clarify that WESTON_CAP_EXPLICIT_SYNC applies to just the
renderer.
- Check for EGL_KHR_wait_sync before using eglWaitSyncKHR.
- Dup the acquire fence before passing to EGL.
Changes in v3:
- Keep acquire_fence_fd in surface instead of buffer.
- Clarify that WESTON_CAP_EXPLICIT_SYNC applies to both backend and
renderer.
- Move comment about non-ownership of in_fence_fd to struct
drm_plane_state definition.
- Assert that we don't try to use planes with in-fences when using the
legacy KMS API.
- Remove unnecessary info from wayland error messages.
- Handle acquire fence for subsurface commits.
- Guard against self-update in fd_update.
- Disconnect the client if acquire fence EGLSyncKHR creation or wait
fails.
- Use updated protocol interface names.
- User correct format specifier for resource ids.
- Advertise protocol for X11 backend with GL renderer.
Changes in v2:
- Remove sync file wait fallbacks.
- Raise UNSUPPORTED_BUFFER error at commit if we have an acquire
fence, but the committed buffer is not a valid linux_dmabuf.
- Don't put buffers with in-fences on planes that don't support
in-fences.
- Don't advertise explicit sync protocol if backend does not

Remove IN_WESTON in favour of the already defined UNIT_TEST which is
used to modify a compilation unit to expose more functions for unit
tests to prod at.
Originally IN_WESTON meant that compilation unit was being compiled for
use in the Weston compositor, but it probably never really did anything
more than change what WL_EXPORT means in matrix.c.
This patch not only simplifies the logic, but it fixes the Meson build
of test-matrix: IN_WESTON was defined there even when matrix.c was being
built outside of Weston, which caused it to depend on libwayland
headers, which were not included in the Meson build of test-matrix.
Test-matrix has no reason to depend in libwayland in any way, so this

clean and easy to read unlike autotools. In practise, configuring and
building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.
More information at http://mesonbuild.com
Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.
This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.
It is expected that the autotools build system will be removed soon
after the next Weston release.

It's a bit surprising that Weston looks different when launched from the root
of the git repo vs from elsewhere.
But it's also technically a security vulnerability: if I launch it from
a directory like /tmp, it might pick up a weston.ini created by another user,
which could then load modules with arbitrary code. Basically, it's the same
problem as including "." in $PATH.

Collect the fallback definitions of static_assert() from desktop-shell
and the test shell, and move them to helpers.h. This allows code
throughout the tree to use static_assert() for build-time assertions,
where it is supported by the compiler.
As GCC goes out of its way to only add static_assert() when C11 has been
explicitly requested - which we don't do - make sure to use the more
widely available _Static_assert() if that is provided.
This will be used in future patches to ensure two array lengths don't go
out of sync.

Now that WESTON_MODULE_MAP supersedes WESTON_BUILD_DIR for libexec
binaries, we don't need to check in WESTON_BUILD_DIR anymore.
There was only one user of weston_config_get_libexec_dir(), so remove
the whole function. There is no reason to export it.
Due to libshared.la being pulled into libweston, this probably was
libweston ABI unintended. Regardless, libweston major has already been
bumped.

The cairo surface used for the icon must be completely given to the
frame as soon as said frame has been created. To prevent both the
window and the frame from sharing ownership of the icon, we set
window->icon_surface back to NULL right after creating or changing the
frame, only keeping it there when no frame has been created yet.

This fetches the _NET_WM_ICON property of the X11 window, and use the
first image found as the frame icon.
This has been tested with various X11 programs, and improves usability
and user-friendliness a bit.
Changes since v1:
- Changed frame_button_create() to use
frame_button_create_from_surface() internally.
- Removed a check that should never have been commited.
Changes since v2:
- Request UINT32_MAX items instead of 2048, to avoid cutting valid
icons.
- Strengthen checks against malformed input.
- Handle XCB_PROPERTY_DELETE to remove the icon.
- Schedule a repaint if the icon changed.
Changes since v3:
- Keep the previous Cairo surface until the new one has been
successfully loaded.
- Use uint32_t for cardinals. Unsigned is the same type except on
16-bit machines, but uint32_t is clearer.
- Declare length as uint32_t too, like in xcb_get_property_reply_t.

Use EGL fence sync objects to emit timepoints for the beginning and the
end of rendering on the GPU. The timepoints are emitted asynchronously
using the sync file fds associated with the fence sync objects. The sync
file fds are acquired using the facilities provided by the
EGL_ANDROID_native_fence_sync extension.
The asynchronous timepoint submissions are stored in a list in
gl_output_state until they are executed, and any pending submissions
that remain at output destruction time are cleaned up.
If timelining is inactive or the required EGL extensions are not
present, then GPU timepoint processing and emission are skipped.
Note that the GPU timestamps returned by sync files are in the
CLOCK_MONOTONIC clock domain, and are thus compatible with the
timeline timestamps (which also are in the CLOCK_MONOTONIC domain).
