Setting up the arguments may consume some of the arguments, e.g. if we
provide a config file or extra modules, then the test harness is
expected to be responsible for freeing those arguments.
Checking the requirements and bailing first means that we never do that,
and thus skipped tests result in leaks. Flip the order so we set up the
args first and skip last, so we can consistently take ownership of all
the provided setup parameters.

ZUC's default mode is to fork for every test case. Unfortunately on
AArch64, fork in an ASan-traced program usually takes around 3.6 entire
seconds. This was leading to the config-parser test timing out.
As none of our remaining ZUC tests even need to fork, just remove all
support for it.

This commit is truly horrible.
We want to run ASan with leak checking enabled in CI so we can catch
memory leaks before they're introduced. This works well with Pixman, and
with NIR-only drivers like iris or Panfrost.
But when we run under llvmpipe - which we do under CI - we start failing
because:
- Mesa pulls in llvmpipe via dlopen
- llvmpipe pulls in LLVM itself via DT_NEEDED
- initialising LLVM's global type/etc systems performs thread-local
allocations
- llvmpipe can't free those allocations since the application might
also be using LLVM
- Weston stops using GL and destroys all GL objects, leading to Mesa
unloading llvmpipe like it should
- with everything disappearing from the process's vmap, ASan can no
longer keep track of still-reachable pointers
- tests fail because LLVM is 'leaking'
Usually, an alternative is to LD_PRELOAD a shim which overrides
dlclose() to be a no-op. This is not usable here, because when
$LD_PRELOAD is not empty and ASan is not first in it, ASan immediately
errors out. Prepending ASan doesn't work, because we run our tests
through Meson (which also invokes Ninja), leading to LSan exploding
over CPython and Ninja, which is not what we're interested in.
It would be possible to inject _both_ ASan and a dlclose-does-nothing
shim DSO into the LD_PRELOAD environment for every test, but that seems
even worse, especially as Meson strongly discourages globbing for random
files in the root.
So, here we are, doing what we can: finding where swrast_dri.so (aka
llvmpipe) lives, stashing that in an environment variable, and
deliberately leaking a dlopen handle which we never close to ensure that
neither llvmpipe nor LLVM leave our process's address space before we
exit.

This is adding basically a copy of alpha-blending-test.c. The difference
is that here we use ICC files to set up the output color profile, and
then test light-linear blending only. BLOCK_WIDTH is set to 1 to fit
inside the output size used by the fixture setup, which is smaller than
in the original, but does not change the results.
The test is aimed at testing how color-lcms module succeeds in
linearizing the output of different ICC output profiles. Incorrect
linearization should cause changes in blending results.
The tolerance is taken from the currently achieved error statistics
(1.40908) and rounded up a little to achieve a suitable margin.

Switch from per-channel max error tolerance to max two-norm (Euclidean
distance) error. Geometrically this means that previously the accepted
volume was a +/- tolerance cube around the reference point, and now it
is a sphere with tolerance radius.
The real benefit is simplifying the code.
The error tolerance are also changed to float. Integers cannot represent
values between 1 and 2, and the jump from 1 to 2 would have been too
much. AdobeRGB tolerance gets relaxed a bit, while BT2020 tolerance
becomes stricter. The new tolerance values are the reported achieved
two-norm max errors plus a bit of margin.
Surprisingly the sRGB case tolerances remain strictly at zero, and
that's no bug in the test.

The recently introduced rgb_diff_stat value dumping feature logs the
"position" where the value or error was measured. The reference value
was used as the position, but the problem with the reference value is
that it is an output value and not an input value. Therefore mapping
that back to which input values promoted the error is not easy.
Fix that problem by passing the position explicitly into
rgb_diff_stat_update(), just like it is already passed in to
scalar_stat_update().
Currently the only user simply passes the reference value as position,
because there the input value is also the reference value. This is not
true for future uses of rgb_diff_stat.

Seems it will be common to print all four min/max/avg sets of errors, so
move the printing code into a shared place.
While 0.0-1.0 is the natural range for color values, people are often
accustomed to working with 8-bit or even 10-bit pixel values. An error
of +/- 1 in 8-bit is more intuitive than +/- 0.004 in floating-point.
Hence 'scaling_bits' is added so the caller can determine the value
scaling. This will scale both the reported error numbers, and the
recorded error positions (rgb-tuples), so they are all comparable.
I'm happy to get rid of those two macros as well.

We treat the argv we pass into the compositor as its to mangle, just as
it is free to do so for POSIX argv. To support this, we stash argv away
and free the saved copy later so as to not leak.
This works perfectly, except when we never call the compositor at all,
and have no saved array to free. Make sure we free the args in this
case, which can be seen as a leak of any generated args when a test
skips on preflight checks, e.g. drm-smoke when not running in CI.

color space is correct.
The common theme in this test program is to create ICC profiles to be
used as output profiles. In the future this can include more kinds of
testing, e.g. linear blending. OTOH, this test program will always be

Added cLUT profile creation to validate linearization algorithm
for DToB3 tag (direction dev to PCS). The 3DLUT is
built by using raw matrix conversion from dev to XYZ and reverse
(XYZ to device).
The test uses floating point pipeline, known as unbounded mode of LCMS.
The details are described in ICCSpecRevision_02_11_06_Float.pdf
The purpose of these new test cases is to keep the GL-renderer 3D LUT
path tested even after color-lcms and GL-renderer start using
specialized matrix-shaper paths.
These also exercise build_eotf_from_clut_profile() in color-lcms, but do
not actually verify it. These cases only test that the recovered EOTF
and its inverse produce an identity mapping together.
BT.2020 is not used in these tests, because the RGB-XYZ conversion
matrix does not stay inside [0.0, 1.0] in either direction, which would
be a problem for the 3D LUT element in the multiProcessingElement
pipelines. Handling that would have been possible, but testing with
AdobeRGB color space should suffice while keeping the test code from
being even more complicated.
roundtrip_verification() tests that we succeed in creating cms
pipelines correctly in both directions so that the resulting ICC file is
better behaved. The Weston test itself only cares about the BToD
direction.

That conversion allows encoding transfer funtions in ICC files and

This all is a result of what I learnt while working on
https://gitlab.freedesktop.org/pq/fourbyfour
Computing the residual error with infinity norm comes straight from
fourbyfour documentation on how to evaluate matrix inversion error.
Most of the hard-coded test matrices have been generated with fourbyfour
project as well, as it contains the generator code. The matrices are
hard-coded here also to make testing faster, but primarily because the
generator code needs BLAS and LAPACK, and having those as Weston
dependencies would be far too much just for this.

This test program was useful a decade ago when weston_matrix_invert()
was being developed. It was a manual test program that ran for a certain
number of seconds and required human interpretation of numbers to see if
results were acceptable or not. Hence it was foundamentally unsuitable
for CI.
The way it generated random matrices for inversion testing was also very
naive, and it used the determinant value to determine invertability
which is completely bogus. This made it also a bad test for correctness.

shell-utils contains a number of helpers which are currently in use by

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).

Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.
Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.
I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.
Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

The union keeps the old .r, .g and .b addressing working. The static

Unfortunately initializers need to be corrected everywhere. Field .a is

and white point is D65. Use INTENT_ABSOLUTE_COLORIMETRIC to avoid BPC.
Input profile is always sRGB and it is used internally by Weston as
stock profile.
2. Use these hardcoded matrixes as part of pipeline 1DLUT->3x3->1DLUT.
The diagnostic code to retrieve the transform matrix is availble into
test in the comments. The conversion matrixes generated for the
following cases:
- sRGB to sRGB (unity)
- sRGB to adobeRGB
- sRGB to BT2020
3. Compare GPU shaders(gl texture3D) vs manual pipeline calculation
Use different max tolerable error per transform.
There are comments how number of points in 3DLUT is related to tolerance.
Tolerance depends more on the 1D LUT used for the inv EOTF than
the tested 3D LUT size: 9x9x9, 17x17x17, 33x33x33, 127x127x127.
4. Enable build matrix-shaper test if color-management-lcms is enabled.

This fixes a leak found running drm-smoke-test with ASan. Do not forget
to call prog_args_fini() when:
- skipping DRM-backend tests because we don't have
WESTON_TEST_SUITE_DRM_DEVICE set.
- we fail to acquire the lock needed to run DRM-backend tests.

We need to unlink this before freeing it since it's being called from

This simulates an output removal which should trigger a crash when
the compositor is shutdown abruptly by having a view with a listener installed
on its output_destroy signal.
This patch assumes that weston_compositor_remove_output() has already
been amended to use the more safer version for triggering signal
emission.
As both shells use this construct it should catch any potential signal
corruption.

drm-smoke-test can't run at the same time as anything else which touches
DRM devices. This includes any test which would use the GL renderer or
GL/GBM on the client side, since they will open DRM devices to probe
them at init time.

This is prompted by the spurious CI failure
https://gitlab.freedesktop.org/wayland/weston/-/jobs/13891809
saying:
31/36 output-damage TIMEOUT 122.52s 8 subtests passed
32/36 output-transforms TIMEOUT 122.52s 16 subtests passed
33/36 subsurface TIMEOUT 122.52s
34/36 xwayland TIMEOUT 122.51s
35/36 ivi-shell-app TIMEOUT 122.51s
ERROR: Job failed: execution took longer than 5m0s seconds
That is hitting both kinds of timeouts at the same time: the per-test
timeouts, and the CI job total timeout.
That run seems to have had a particularly ill fortune, as a simple retry
finished the same job in 2 minutes, and the longest running test took
only 24 seconds.
Nevertheless, by Daniel Stone's suggestion let's bump both timeouts:
- the per-test timeout to 120 seconds, which with the multiplier in CI
goes up to 8 minutes
- the job timeout for all build related jobs to 15 minutes
The timeout for tests_standalone is not bumped as we are not adding
significant amounts of new tests there.

Since commit "drm-formats: save result of intersection in the first
array", every block of code where weston_drm_format_array_create() and
destroy() are being called could use init() and fini() instead.
Remove these two functions from the API to make it leaner. This patch
also modifies the code that depends on these functions to use init() and
fini().

In the current API, we have some set operations: join, intersect and
subtract. Both join and subtract receives two DRM format arrays and save
the result in the first one.
For the intersection we have a slightly different approach, what makes
the API weird. We don't save the result in the arguments, instead we
return a new array with the result.
Modify weston_drm_format_array_intersect() in order to make it similar
to the other two set operations.

Our core test structure is 36 bytes wide. Declaring it with a 32-bit
alignment should thus stripe it to 64 bytes. For some reason, clang+lld
lays them out with a 96-byte stride within the section (does it want an
entire 32-bit word when building with ASan?), getting the code wildly
confused when it tries to step through the structures.
So we could fix all our tests to avoid the fragile section dance, or we
could just waste another 4 bytes per test definition by bumping the
alignment up to 64 bytes, which seems to do enough to magically accord
with what clang+lld+ASan expect.

This fixes all ASan reported leaks in this test.
This test program has several tests named *_multiple that just run
another test function 30 times. Previously without cleanup all the
created clients would be left lingering, but now they are torn down. Ths
might cause a change in test behaviour, although that was never the
intention:
> It is intentional to run it so many times, but it is not intentional
> to run a hundred clients at a time. The problem is that currently we

The intention for the repeat testing is that as the Weston instance
remains from test to another, each test needs to undo its changes to the
devices. Failing to correcntly undo would accumulate devices.
