Quoting Carlos:
The META_PRIORITY_EVENTS ± 1 happening below are in order to set these idles
and timeouts in a priority that is relative to the literal GDK event priority,
making those diverge is a likely way to sneakily break things.
But that's unlikely to happen, and decoupling mutter from GTK further
should make it moot, so perhaps it's alright after all.

There are two tests; one checks that clearing with a color that cannot
be represented using 8 bits per channel doesn't loose precision when
painted, then read back using glReadPixels(). Would the texture backing
store have 8 bits per channel instead of 10, we'd get a different value
back.
The other test checks that painting from one fbo to another also doesn't
loose that precision.

The "later" API is used to queue actions in relation to compositing,

This means we can eliminate the use of scattered singletons that isn't
added by the tests or the test framework itself.

Either use the ownership chain, or the explicit test context instance
pointer.

So that we can get the Wayland compositor directly from the context.

This means objects have an owner, where the chain eventually always
leads to a MetaContext. This also means that all objects can find their
way to other object instances via the chain, instead of scattered global
singletons.
This is a squashed commit originally containing the following:
cursor-tracker: Don't get backend from singleton

The backend is needed during construction to get the wacom database.
input-mapper: Pass backend when constructing

For the remote desktop and screen cast implementations, replace getting
the backend from singletons with getting it via the manager classes.
launcher: Pass backend during construction

Instead of passing the (maybe null) launcher, pass the backend, and get
the launcher from there. That way we always have a way to some known

Add a helper function that ensures any queued virtual input events have
been flushed from the input thread. This works by posting a task to the
input thread, which will itself queue another callback back to the main
thread. Once the main thread callback is invoked, the flush call is
unblocked and the function returns. Upon this, any previously emitted
virtual input event should have already passed through the input thread
back into the main thread, however not necessarily fully processed.
For making sure it has been processed, one also have to make sure the
stage has been updated, e.g. via `meta_wait_for_paint()`.

The test does simply "wait" which apparently is not enough to ensure the
client window did resize to the expected dimensions. Use "wait_reconfigure"
and assert that the size after resize is the expected, before going further
at testing its behavior after maximize/unmaximize; it might end up with the
unexpected size after the whole operation.

We put a DEVICE_ADDED or DEVICE_REMOVED event into Clutters event queue
here, so we should also wait for Clutter to process events once.
Just putting an event into the queue doesn't mean it gets processed

wait for a stage update here.

This is an old relic from when ClutterStageView was being added, and
tests were somewhat prepared to be able to test the "X11 style" of
things, with the nested backend some how managing to emulate that.
Lets drop that stuff, it isn't used by the test suite, and isn't useful
anyway; if we want to test X11 configurations, we should use the actual
X11 backend, which didn't make use of this anyway.

The D-Bus runner used by tests, including installed tests, is made to be
reusable from GNOME Shell. To do this, install it and the templates in
the pkgdatadir (e.g. /usr/share/mutter-APIVERSION/tests/), generate a
custom runner for the installed tests that uses the installed script and
templates, and change the non-installed original runner to use the
non-installed templates.
The end goal is to reuse the D-Bus session runner and templates used for
mutter when test running GNOME Shell.

This allows using two separate ICC profiles for one "color profile",
which is necessary to properly support color transform
calibration profiles from an EFI variable.
These types of profiles are intended to be applied using the color
transformation matrix (CTM) property on the output, which makes the
presented output match sRGB. In order to avoid color profile aware
clients making the wrong assumption, we must set the profile exposed
externally to be what is the expected perceived result, i.e. sRGB, while
still applying CTM from the real ICC profile.
The separation is done by introducing a MetaColorCalibration struct,
that is filled with relevant data. For profiles coming from EFI, a
created profile is practically an sRGB one, but the calibration data
comes from EFI, while for other profiles, the calibration data and the
ICC profile itself come from the same source.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2568>
This mocks gsd-colord to enable night ligth at a given temperature. The
test then verifies that the result exactly matches that of the gamma
ramps gsd-color generated for the same temperature and ICC profile.
There are two types of profiles tested; ones with VCGT, i.e. calibrated
profiles, and ones without. These are tested as the VCGT affects how the
gamma curve looks, while the non-VCGT profiles all only rely on
the blackbody temperature to generate a gamma ramp.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2165>
We created device profiles, that we manage the lifetime of in colord,
but color devices can be assigned profiles other than the ones it was
created for. For example, this can include the standard sRGB profile
provided by colord.
To achieve this, keep track of the default profile of the CdDevice as
the "assigned" color profile of the device. Given this profile
(CdProfile), construct a MetaColorProfile that can then be interacted
with as if it was generated by ourself.
The assigned profile (default profile in colord terms) does nothing
special so far, but will later be used to determine how to apply CRTC
gamma ramps etc.
The sRGB.icc file used in the tests was copied from colord. It was
stated in the repository that it has no known copyright restrictions.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
Just as gsd-color does, generate color profiles. This can either be done
from EFI, if available and the color device is associated with a built
in panel, or from the EDID. If no source for a profile is found, none is
created.
The ICC profiles are also stored on disk so that they can be read by
e.g. colord. The on disk stored profiles will only be used for storing,
not reading the profiles, as the autogenerated ones will no matter what
always be loaded to verify the on disk profiles are up to date. If a on
disk profile is not, it will be replaced. This is so that fixes or
improvements to the profile generation will be made available despite
having run an older version earlier.
After generating, add some metadata about the generated file itself
needed by colord, i.e. file MD5 checksum and the file path.

gsd-color provides this API, which exposes details about the night light
state. Currently, gsd-color also turns this state into CRTC gamma
changes, but this will eventually change, and this is a preparation for
this.

This will be needed for adding colord integration without breaking
testing.
The test context is altered to make sure any left over color devices are
cleaned up before starting. This means it becomes possible to run a test
case multiple times without having to restart meta-dbus-runner.py.
Note: Don't use os.getlogin() to get the current username; as that
requires a controlling terminal.

We fairly consistently had multiple monitors with the whole
vendor,product,serial tuple identical. If we start relying on making
monitors a bit more unique, e.g. for colord integration, we need to make
two monitors connected distinguishable in order for tests to properly
reflect reality and excercise the correct colord integration paths.

Until recently, mutter-test-runner called into libraries that
indirectly depend on (mutter's fork of) Clutter, but did not actually
call into Clutter itself. Commit 1bf70334 "tests/runner: Make test
runner use the headless backend" gave it a direct call into Clutter,
which means the runtime linker will fail unless the executable's
RUNPATH is sufficient to find Clutter.
For future-proofing, do the same for the other test executables.

If two modes are roughly the same, they should probably use the same UI
scaling factor. I.e. for the same monitor, if a 4K mode was configured to
have a certain scaling factor, and we generate a new configuration with
a similar sized 4K mode, we should re-use the scale previously
configured; however if we e.g. go from a 4K mode to a FHD mode, we
shouldn't.
This allows implementing better hueristics when using the switch-config
feature, where we'd be less likely to loose the for a certain monitor
mode combination previously configured scaling factor.

The following implicit definition for `transform()` did not

The test case checks that the stage views of hidden actors are
not updated when the views of the visible outer parent change.
The check for the outer parent's updated stage views currently
relies on ClutterFixedLayout not excluding hidden children in
its size request: As the container doesn't contain any visible
children at that point, its size would change to 0x0 and end
up on no stage view (rather than the assumed two).
Avoid that oddity by giving the outer container a fixed size,
so that the visibility of its child doesn't affect the test
when we fix ClutterFixedLayout.

Add `sync_effects_completed()` and `verify_view()` in
order to allow Wayland test clients to trigger verifications
and add convenience functions to use them to client-utils.
Notes:
- `sync_effects_completed()` works in two stages in order
to ensure it doesn't race with window effects. By the time
`sync_effects_completed()` is processed, an effect could
already have ended or not yet been scheduled. Thus we
defer a check for pending effects to the next paint cycle,
assuming that by then they should have been scheduled.
- `meta_ref_test_verify_view()` internally triggers the
`paint` signal for the stage which is why it can not be run
in the after-paint signal handler.

The final tick of a timeline is >= its duration, but when using ticks that
are slightly in the future ("next presentation time") this means the final
tick will execute and complete the timeline up to one frame interval before
the timestamp of that final tick.
For the single clock test we now just check if the overall duration is
within one frame of the expected timeline duration.
The dual clock (switching) test needs a threshold of two frames because
starting each new clock creates a phase shift (error) of up to one frame.

The roundtrip in the handle-configure function could in theory (and in
practice in the future) happen to receive another configure event. If we

We created pipes for the stdout of the spawned mock services. This

If one would end up with an actor attached to mapped actor, where the
attached actor doesn't itself have an up to date stage view list while
listening on the stage for updating, when clearing the stage views of
the list, anything that would query the stage views list at this time
would end up accessing freed memory.
This could happen if
1) An actor was added to a newly created container actor attached to
the stage
2) The actor got a timeline attached to it
3) The actor was moved to a container that already was mapped
4) A hotplug happened
After (1) both the container and actor would not have any stage views.
After (2) the timeline would listen on the stage for stage views
updates. After (3) the actor would still listen on the stage for stage
views updates. When (4) happened, the actor would be signalled when the
stage got its stage view cleared, at which point it would traverse up
its actor's tree finding an appropriate stage view to base its animation
on. The problem here would be that it'd query the already mapped
container and its yet-to-be-cleared stage view list, resulting in
use-after free, resulting in for example the following backtrace:
0) g_type_check_instance_cast ()
1) CLUTTER_STAGE_VIEW ()
2) clutter_actor_pick_frame_clock ()
3) clutter_actor_pick_frame_clock ()
4) update_frame_clock ()
5) on_frame_clock_actor_stage_views_changed ()
6) g_closure_invoke ()
7) signal_emit_unlocked_R ()
8) g_signal_emit_valist ()
9) g_signal_emit ()
10) clear_stage_views_cb ()
11) _clutter_actor_traverse_depth ()
12) _clutter_actor_traverse ()
13) clutter_actor_clear_stage_views_recursive ()
14) clutter_stage_clear_stage_views ()
...
Avoid this issue by making sure that we don't emit 'stage-views-changed'
signals while the actor tree is in an invalid state. While we now end up
traversing tree twice, it doesn't change the Big-O notation. It has not
been measured whether this has any noticible performance impact.

Previously, we were waiting up to 300ms for the signal, then proceeding
anyway. However, 300ms is not necessarily long enough to wait on an
autobuilder that might be heavily loaded, particularly if it's a non-x86
with different performance characteristics.
Conversely, if mutter responds to the D-Bus signal from the mock sensor
before we have connected to the signal, then we cannot expect to receive
the signal - it was already emitted, but we missed it. In this case, we
need to avoid waiting.
One remaining use of wait_for_orientation_changes() that would previously
always have timed out was in
meta_test_orientation_manager_has_accelerometer(), which does not
actually expect to see an orientation-changed signal. Make this wait
for the accelerometer to be detected instead.

This feature was configured depending on whether the Cogl backend
reported COGL_WINSYS_FEATURE_MULTIPLE_ONSCREEN or not. All cogl backends
do report this, so any code handled the 'static' case were never used.
While we only ever use one stage, it's arguable more correct to
consilidate on the single stage case, but multiple stages is something
that might be desirable for e.g. a remote lock screen, so lets keep this
logic intact.
This has the side effect of completely removing backend features, as
this was the only left-over feature detection that they handled.

When a test failed, an exception would be raised. This meant that the
mocked service would stay alive, and the test case being run eventually
failing due to a timeout, not the failure itself.

teared down.

In X11 when we switch to another tty all the the signals are blocked (as
the display fd is not replying back to polling, causing the main loop to
stop), and they are all handled once we switch back to the tty.
This is not a problem for most of external events, but in case of
accelerometer changes, once we reactivate a mutter session we'll get
them all together, causing lots of monitor reconfigurations leading to
black screen for some seconds and most of the times to a wrong
configuration being applied.
To avoid this, batch all these events using an idle to only apply the
last one we got in a loop.

Create a test system bus and use it to run all the tests, add a mock
SensorsProxy (via dbusmock template) server that implements the

To make testing easier, the service is created on request of a proxy for
it, whose lifetime controls the mock service lifetime as well.
This is done using a further mock service that is used to manage the
others, using python-dbusmock to simplify the handling.
Add basic tests for the orientation manager.
As per the usage dbusmock, we're now launching all the tests under such

When we get an orientation event we don't care about keeping track of the
configuration changes, but actually we can consider the new configuration
just a variant of the previous one, adapted to floating device hardware
events, so we only want to apply it if possible, but we don't want to keep
a record of it for reverting capabilities.
Doing that would in fact, break the ability of reverting back to an actual
temporary or persistent configuration.
For example when device orientation events happen while we're waiting for
an user resolution change confirmation, we would save our new rotated
configuration in the history, making then impossible to revert back to
the original persistent one.
So in such case, don't keep track of those configurations in the history,
but only keep track of the last one as current, checking whether the
new current is child or sibling of the previously one.

With some resolutions (such as 4096x2160) we may compute duplicated
scale factors because we used a too wide threshold to check for an
applicable value.
In fact, while when we're at the first and last values it's fine to
search applicable values up to SCALE_FACTORS_STEP, on intermediate ones
we should stop in the middle of it, or we're end up overlapping the
previous scaling value domain.
In the said example in fact we were returning 2.666667 both when
looking to a scaling value close to 2.75 and 3.00 as the upper bound of
2.75 (3.0) was overlapping with the lower bound of 3.0 (2.75).
With the current code, the lower and upper bounds will be instead 2.875.
Adapt test to this, and this allows to also ensure that we're always
returning a sorted and unique list of scales (which is useful as also
g-c-c can ensure that this is true).
