Without this fix, we have randomly been getting CI failures due to
LeakSanitizer itself crashing after all the tests in a program have
succeeded. This has been happening randomly for a long time, but
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/1486
made it very reliably repeatable in the job x86_64-debian-full-build
(and no other job) in the test-subsurface-shot program.
--- Fixture 2 (GL) ok: passed 4, skipped 0, failed 0, total 4
Tracer caught signal 11: addr=0x1b8 pc=0x7f6b3ba640f0 sp=0x7f6b2cc77d10
==489==LeakSanitizer has encountered a fatal error.
I was also able to get a core file after twiddling, but there it ended
up with lsan aborting itself rather than a segfault.
We got some clues that use_tls=0 might work around this, from
https://github.com/google/sanitizers/issues/1342https://github.com/google/sanitizers/issues/1409
and some other projects that have cargo-culted the same workaround.
Using that cause more false leaks to appear, so they need to be
suppressed. I suppose we are not interested in catching leaks in glib
using code, so I opted to suppress g_malloc0 altogether. Pinpointing it
better might have required much more slower stack tracing.
wl_shm_buffer_begin_access() uses TLS, so no wonder it gets flagged.
ld-*.so is simply uninteresting to us, and it got flagged too.
Since this might have been fixed already in LeakSanitizer upstream, who
knows, leave some notes to revisit this when we upgrade that in CI.
This fix seems to make the branch of
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/1486
in my quick testing.

When using some features from LittleCMS in our CI, we are seeing some
crashes on the address sanitizer. Bumping the LittleCMS version fixes
that. So build and install a more recent version of LittleCMS on our CI.
We chose version 2.16 because it introduces the function
cmsGetToneCurveSegment(). We already make extensive use of that in our
codebase, so it is a good idea to have that on our CI as well.
Now color-curve-segments.c will start to get build on the CI, as
HAVE_CMS_GET_TONE_CURVE_SEGMENT will be true. So we also fix a minor
issue in which we were comparing int with uint in this file, what was
caught after experimenting bumping the LittleCMS version.

Now that we've concluded the Xwayland/fontconfig stuff, we don't
actually need a per-test wrapper; we can just set the options globally.
It turns out that we don't need to set the options at all anyway, since
the previous commit adds the LSan suppressions to all test runs, and
LSan is enabled by default, so we can just bin it.

This patch introduces a small library wrapper around XCB to be used in
Xwayland tests.
It's being designed such that we do not advance without accounting for
all X11 events when changing the window state. It adds a fence that
waits for all events to be processed, and only after all the events have
been accounted for, to proceed further, resuming execution of the
tests.
This works by keeping a tentative_state list for the client and a
window state that gets applied when the event we waited for has been
received.
This is useful in test clients, which could verify at the end after
receiving all events that the correct state has been applied. Acts as a
way to verify that the we never get or have a different state than the
one we expect.
With it, this converts test-xwayland to using libxcb (together with
xcb-cursor-dev) rather than using Xlib, and with it it removes any Xlib
dependency we might have in the tests.
This only adds support for map/unmap/create/destroy/property notify.
A follow-up would be to expand this library to track window movement
and resizing.

While developing the new color management, keeping these old plugins
working would require extra work. Let's deprecate these to see if anyone
cares about them, pending removal after the Weston 11.0.0 release.
CI will keep building these in the "Full build" configuration only. Doc

no longer built.

Unfortunately just adding suppressions isn't enough; the build of Expat
we have in our CI system does not have frame pointers, so ASan's fast
unwinder can't see through it. This means that the suppressions we've
added won't be taken into account.
For now, disable the fast unwinder for the Xwayland test only. Disabling
it globally is not practical as it massively increases the per-test
runtime, so here (to avoid polluting the build system), we use a
per-test wrapper to selectively choose the unwinder.

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.

Add VGEM to the Linux image that runs in the CI. There are tests that we
plan to add in the future that need this.
This brings a complication, as we already have VKMS in the image. The
order in which DRM devices are loaded is not always the same, so the
node they receive is non-deterministic. Until now we were sure that VKMS
(the virtual device we use to run the DRM-backend tests in the CI) would
be in "/dev/dri/card0", but now we can't be sure. To deal with this
problem we find the node of each device using a one-liner shell script.
This commit also updates the documentation section that describes
specificities of DRM-backend tests in our test suite.

These formats are useful because they are often easier to produce
on CPU than half-float formats, and abgr16161616 has both >= 10bpc
color channels and adequate alpha, unlike abgr2101010.
The 16-bpc textures created from buffers with these formats require
the GL_EXT_texture_norm16 extension.
As WL_SHM_FORMAT_ABGR16161616 was introduced in libwayland 1.20,
update Weston's build requirements and CI.
The formats also needed to be registered in the pixel format table,
and defined in a fallback path if recent libdrm is not available.

I do not know what happens if multiple jobs declare

Recently, the MR diffs have the coverage annotations, but there was a

Let's make sure the cobertura report Gitlab will use is from the "main"
build only: 64-bit Debian with full features and gcc.

As the drm-smoke test randomly reports having the connector disabled,
and with it libseat reports setMaster errors, this enables DRM backend
debug messages for the kernel, and for libseat in an attempt to
track down the issue, whenever it might happen again.
These are pretty harmless, in terms of data being generated as we only
have a single DRM test using VKMS, and the libseat debug message aren't
that verbose, so we're safe keeping them for the time being.

saying:

32/36 output-transforms TIMEOUT 122.52s 16 subtests passed

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.
