7ef26886f5 gl-renderer: implement intermediate framebuffer (shadow)
Proper color management will need blending done with linear light pixel
values, that is, EOTF applied before blending, and then inverse-EOTF
applied for scanout after blending. The simplest way to set that up is
to use an intemediate framebuffer a.k.a shadow buffer containing the
composited image in linear light values, then blit from that to the
actual framebuffer.

This patch implements the shadow buffer, but the linear light
blending is left for another patch. This allows GL-renderer to turn
WESTON_CAP_COLOR_OPS on.

Half-float is chosen as the buffer format because linear light values
require more bits to encode with sufficient precision than the usual
non-linear pixel values.

v2: Use /* */ instead of // (Pekka)
    Rename fbo and tex to shadow_{fbo,tex} (Pekka)
    Check for OpenGLES capabilities before creating
    shadow_{tex,fbo} (Pekka)

ef81388466 tests: introduce struct fixture_metadata
This allows tests to give a meaningful name for their fixture setups
when they use more than one of them.

If a test uses DECLARE_FIXTURE_SETUP_WITH_ARG(), it must now pass a
third argument naming the field which is struct fixture_metadata. This
also means that the fixture setup data must now be a struct, it cannot
be a plain type anymore. A compiler error is generated if the field type
is not the expected one.

All tests using DECLARE_FIXTURE_SETUP_WITH_ARG() and converted to the
new form and given names for their fixture setups.

The fixture setup names not actually used yet, that will be another
patch.

ae12b9596d tests: add yuv-buffer test
This adds a test to ensure that the wl_shm formats YUV420, NV12 and YUYV
are decoded and converted to RGB correctly in GL-renderer.

The test deliberately uses a 256 x 256 test image so that effects from
width vs. pitch vs. stride cannot be observed, and row padding is zero.
Also padding between planes is zero. Attempting to use a test image with
less "round" dimensions lead to stride mismatch in GL-renderer, likely
due to GL_UNPACK_ALIGNMENT being left at value 4. It is unclear if YUV
wl_shm buffers' row stride needs to be aligned to 4 bytes or not, so I
did not pursue fixing it. GL-renderer seems to be confusing width, pitch
and stride even further, and not e.g. allow padding with ARGB buffers.
See also: https://gitlab.freedesktop.org/wayland/weston/-/issues/354

Furthermore, the test arranges so that each 2x2 pixel block has the same
color. This avoids having to consider chroma siting when sub-sampling.
This way all the test cases can use the same reference image.

As they are identical and this won't change, make the test suite

Besides the cleanup, this change will also allow us to use the
DRM writeback screenshooter in the test suite, as the test suite
implementation is hardcoded to use a renderer based screenshooter.

32a5acde5b tests: add mechanism to change Weston's behavior when running certain tests
There are some specific cases in which we need Weston to
behave differently when running in the test suite. This
adds a new API to allow the tests to select these behaviors.

For instance, in the DRM backend we plan to add a writeback
connector screenshooter. In case it fails for some
reason, it should fallback to the renderer screenshooter
that all other backends use. But if we add a test to
ensure the correctness of the writeback screenshooter,
we don't want it to fallback to the renderer one, we
want it to fail. With this new API we can choose to
disable the fallback behavior specifically for this test.

ad41a88535 tests: Add a way to write a Weston.ini inside the test
Currently doesn't exist a standard way to write a weston.ini inside a test.

Here, two new functions `weston_ini_setup` and `cfgln` are introduced to
help the test writer to write a weston.ini file and load it to the test.
And `internal-screenshot-test` is converted to use the new method of write
a weston.ini. This conversion serves as example and initial API test.

The tester needs to call `weston_test_harness_execute_as_client` or
`weston_test_harness_execute_as_plugin` in the same way as before.
The `weston_ini_setup` will fill the setup->config_file with the
correct path to the weston.ini file.

The main design goal is to avoid pre-made or build-made weston.ini(s)
and keep the test as self-contained as possible.

e8a8c13e0d tests: add support to run drm-backend tests locally
With this patch we add support to run DRM-backend tests locally
in the test suite. For now this won't work in the CI, as there
are no cards available. But the plan is to achieve this by using
VKMS (virtual KMS) in the future.

To run DRM-backend tests locally, first of all the user has to
set the environment variable WESTON_TEST_SUITE_DRM_DEVICE to
'card0', 'card1' or any other device where he wants to run
the tests. Also, for now it only works if it is run as root,
but in the future this problem will be solved.

The tests will run on a non-default seat. The reason for that
is that we want to avoid opening input devices unnecessarily.
Also, since DRM-backend usage requires gaining DRM master status
on a DRM KMS device, nothing else must be using the device at
the same time. To achieve this we use a lock to run the
DRM-backend tests sequentially.

7b37b4d3d7 tests: properly select renderer for DRM-backend
The test suite is dealing only with headless-backend tests.
In order to make it able to run DRM-backend tests, we have
to properly select the renderer that it will use.

This patch add the command line option --use-pixman if the test
defines the DRM-backend renderer as RENDERER_PIXMAN, and it will
add nothing to the command line if it defines RENDERER_GL (the
DRM-backend default renderer is already GL). Also, if the user
defines the DRM-backend renderer as RENDERER_NOOP, the test will
fail (as it should, since DRM-backend does not implement it).

e8033e3dd1 tests: don't use width and height for drm/fbdev backend tests
In the test suite we have some default options which
are command line arguments used by most of the tests.
Two of these are width==320 and height==240. But
when we have DRM or fbdev backends, width and height
are not possible command line arguments. This makes
impossible to run tests that uses one of these types
of backends, as the compositor won't open if the
command line string is wrong.

Fix this by not passing command line arguments width
and height if the backend is DRM or fbdev.

This test ensures that
	"pixman-renderer: half-fix bilinear sampling on edges"
keeps on working.

Unlike in the original report
https://gitlab.freedesktop.org/wayland/weston/issues/373, here we use buffer
scale 2 instead of output scale 2 to trigger bilinear filter. The effect is the
same, the actual resulting image in the failing case is just a little

97359ba5c5 tests: add output transform tests
This goes through all output transforms with two different buffer transforms
and verifies the visual output against reference images.

This commit introduces a new test input image 'basic-test-card.png'. It is a
small image with deliberately odd and indivisible dimensions to provoke bad
assumptions about image sizes. It contains red, green and blue areas which are
actually text that makes it very obvious if you have e.g. color channels
swapped. It has a white thick circle to highlight aspect ratio issues, and an
orange cross to show a mixed color. The white border is for contrast and a 1px
wide detail. The whole design makes it clear if the image happens to be rotated
or flipped in any way.

The image has one pixel wide transparent border so that bilinear sampling
filter near the edges of the image would produce the same colors with both
Pixman- and GL-renderers which handle the out-of-image samples fundamentally
differently: Pixman assumes (0, 0, 0, 0) samples outside of the image, while
GL-renderer clamps sample coordinates to the edge essentially repeating the
edge pixels.

It would have been "easy" to create a full matrix of
every output scale & transform x every buffer scale & transform, but that
would have resulted in 2 renderers * 8 output transforms * 3 output scales *
8 buffer transforms * 3 buffer scales = 1152 test cases that would have all
ran strictly serially because our test harness has no parallelism inside one
test program. That would have been slow to run, and need a lot more reference
images too.

Instead, I chose to iterate separately through all output scales & transforms
(this patch) and all buffer scales & transforms (next patch). This limits the
number of test cases in this patch to 56, and allows the two test programs to
run in parallel.

I did not even pick all possible scale & transform combinations here, but just
what I think is a representative sub-set to hopefully exercise all the code
paths.

080d85b8fb tests: implement client_destroy()
It turns out that if the client is not explicitly destroyed, it will remain
connected until the compositor shuts down because there is no more a client
process that would terminate.

Usually this is not a problem, but if a test file has multiple screenshooting
tests, the windows from earlier tests in the file will remain on screen. That
is not wanted, hence implement client destruction.

To properly destroy a client, we also need a list of outputs. They used to be
simply leaked. This does not fix wl_registry.global_remove for wl_outputs, that
is left for a time when a test will actually need that.

This patch makes only ivi-shell-app test use the new client_destroy() to show
that it actually works. The added log scopes prove it: destroy requests get
sent. Sprinkling client_destroy() around in all other tests is left for a time
when it is actually necessary.

ivi-shell-app is a nicely simple test doing little else, hence I picked it.

GL-renderer seems to round instead, which causes the +1 in background color
channel values.

babb3b3bc2 tests: thread-based client harness
This replaces the old test harness with a new one.

The old harness relied on fork()'ing each test which makes tests independent,
but makes debugging them harder. The new harness runs client code in a thread
instead of a new process. A side-effect of not fork()'ing anymore is that any
failure will stop running a test series short. Fortunately we do not have any
tests that are expected to crash or fail.

The old harness executed 'weston' from Meson, with lots of setup as both
command line options and environment variables. The new harness executes
wet_main() instead: the test program itself calls the compositor main function
to execute the compositor in-process. Command line arguments are configured in
the test program itself, not in meson.build. Environment variables aside, you
are able to run a test by simply executing the test program, even if it is a
plugin test.

The new harness adds a new type of iteration: fixtures. For now, fixtures are
used to set up the compositor for tests that need a compositor. If necessary, a
fixture setup may include a data array of arbitrary type for executing the test
series for each element in the array. This will be most useful for running
screenshooting tests with both Pixman- and GL-renderers.

The new harness outputs TAP formatted results into stdout. Meson is not
switched to consume TAP yet though, because it would require a Meson version
requirement bump and would not have any benefits at this time. OTOH outputting
TAP is trivial and sets up a clear precedent of random test chatter belonging
to stderr.

This commit migrates only few tests to actually make use of the new features:
roles is a basic client test, subsurface-shot is a client test that
demonstrates the fixture array, and plugin-registry is a plugin test. The rest
of the tests will be migrated later.

Once all tests are migrated, we can remove the test-specific setup from
meson.build, leaving only the actual build instructions in there.

The not migrated tests and stand-alone tests suffer only a minor change: they
no longer fork() for each TEST(), otherwise they keep running as before.

Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.

All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
  did not fit there.

Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.

Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

This was forgetting to remove the compositor destroy listener if init failed,
which would lead to use-after-free on compositor tear-down. Found by
inspection.

f38d4458f7 tests: remove static data from presentation
While get_presentation() will only ever be called once (making the caching of
the return value moot), it is good to stop using the static variable as it
would cause surprising problems if anyone adds more tests here and runs it
under the new test harness.

It was leaked before and continues to be so.

f8086fb839 tests: remove static data from ivi-layout-test-client
Using static data will mess things up when the test harness no longer fork()'s
each sub-test. Hence it needs to be converted to "normal" data.

Unfortunately here the cached value was actually used, so keeping that
behaviour is a handful. Yes, it was all leaked also before.

Just one test call this only once, so the cached value will never be useful.

Stop using static data, it sets a bad example. If more tests were added, things
would start failing when forking is removed from the test harness.

d19c55c75e tests: remove static data from ivi-layout-test-plugin
I cannot see any reason why this should be static data. But if it is static
data, it will prevent re-entering wet_main() to run tests with this plugin, so
replace it with "normal" data.

This caching is actually never hit. I tested by making the early return abort()
instead and all works just fine.

Remove the caching. The static variable will cause problems when we stop
fork()'ing for each test case.

9722ac62f0 tests: surface-screenshot needs libshared
surface-screenshot-test.c uses file_create_dated() provided by libshared, so it
needs to link libshared.

This was not a problem when unresolved symbols during build were allowed and
the symbols was provided by the weston executable which accidentally exported
all libshared symbols. This would become a problem when we disallow unresolved
symbols project-wide, so fix it.

71ff95a544 build: separate deps for int and ext libweston users
We have two kinds of libweston users: internal and external. Weston, the
frontend, counts as an external user, and should not have access to libweston
private headers. The shell plugins are external users as well, because we
intend people to be able to write them. Renderers, backends, and some plugins
are internal users who will need access to private headers.

Create two different Meson dependency objects, one for each kind.

This makes it less likely to accidentally use a private header.

Screen-share is a Weston plugin and therefore counts as an external user, but
it needs the backend API to deliver input. Until we are comfortable exposing
public API for that purpose, let it use internal headers.

deae98ef45 shared: Use memfd_create() when available
This (so-far) Linux-only API lets users create file descriptors purely
in memory, without any backing file on the filesystem and the race
condition which could ensue when unlink()ing it.

It also allows seals to be placed on the file, ensuring to every other
process that we won’t be allowed to shrink the contents, potentially
causing a SIGBUS when they try reading it.

This patch is best viewed with the -w option of git log -p.

It is an almost exact copy of Wayland commit

4f5e360180 build: simplify include_directories
Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/
headers.

Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
 #include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.

Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.

c232f8d934 Unify the include style of shared/ headers
When all shared/ headers are included in the same way, we can drop unnecessary
include seach paths from the compiler.

This include style was chosen because it is prevalent in the code base. Doing
anything different would have been a bigger patch.

This also means that we need to keep the project root directory in the include
search path, which means that one could accidentally include private headers
with

	#include "libweston/dbus.h"

or even

	#include <libweston/dbus.h>

IMO such problem is smaller than the churn caused by any of the alternatives,
and we should be able to catch those in review. We might even be able to catch
those with grep in CI if necessary.

The "bad" include style was found with:
$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'
