meta_keymap_x11_replace_keycode currently reports to the X server
that the key types data is changed when adding a key to the keymap.
It's not changed. The number of key types is the same, and none of
them are modified.
This has two bad side effects:
1) It sends all of the key types data into the request
2) It hits a bug in the X server leading to the request getting
rejected entirely. See:
https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/761
Furthmore, the changed structure used to report to the X server
that the key types data is changed doesn't actually need to modified
at all in the function. It's already prepped by libX11 with the
correct state for the changes mutter is doing when
XkbChangeTypesOfKey is called.
This commit addresses the above two problems by just removing the
lines causing the issues.

Keys in the reserved keycode list are always added for the first group.
Before the previous commit such keycodes were not found unless that was
the current group. But now that we can also find matching keycodes that
are not directly in the current group, this is not necessary anymore.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1955>
Some keys, such as enter or backspace are only bound to a single group,
even if multiple groups are configured. Because the code was previously
only looking for keysyms in the same group as the current one, no
matching keycodes for these would be found if the current group is not
the first group. This was causing those keys to not work on the X11 OSK.
To fix this use the correct action to convert an out of range group for
that key according to its group_info field.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1955>
This effectively changes meta_keymap_x11_get_entries_for_keyval() to
meta_keymap_x11_get_entry_for_keyval() and moves the check if the
keycode maps to the keyval in the current group there. This simplifies
the code a bit and will allow a followup fix.
As a side effect this now also causes the reserved kecodes to be
searched, if no keycodes were found, rather than just when only ones
matching the wrong groups.

The extra stage update we schedule in `apply_state()` is mainly
needed in two situations:
- a partial update happened only in obscurred or off-screen parts
of a surface
- a surface requests frame callbacks without having done damage,
notably the (in)famous Firefox vsync implementation.
Commit 0330ce1f15 limited the update to cases when the actor
was mapped, breaking it for Firefox in the overview.
Remove the mapped check again and get the stage from the backend,
restoring previous behaviour.

Avoid having laptops suspend or lock as soon as the power cable is
unplugged as the timeout for those actions when on battery are smaller
than the timeouts when on AC.
- laptop is plugged in, and hasn't been used for X minutes
- laptop is unplugged
- the gnome-settings-daemon power plugin sets up its timeouts for
inactivity for the "on battery" case
- those X minutes of inactivity are still counting, and are above
the level of one of the timeouts (say, suspend or lock screen),
mutter fires the timeouts

If the ancestor a window is transient for has already been unmanaged
when the window is activated via meta_window_activate_full while its
transient_for property still points to that ancestor, this will cause
the already unmanaged ancestor to get added to the windows workspace.
This is after the ancestor had its workspace set to NULL when it was
unmanaged, causing this to look like an actual workspace change. Once
the window has been added to the workspace, it will never be removed
again, because the it has already been unmanaged. This confuses things
like the shell window tracker and leads to phantom windows being
considered present for apps that are not even running anymore.

When the native backend is paused we still process the udev events
even though this isn't needed and may just cause unneeded events to be
triggered afterwards.
Since we'll resume with full changes on such event, we can just block
the signal hander when paused and restore it afterwards.

If only gamma changed on drm CRTC's we don't have to rebuild the whole

Since we cache already all the KMS parameters we care about let's check at
each device update if anything has really changed and only in such case
emit a resources-changed signal.
In this way we can also filter out the DRM parameters that when changed
don't require a full monitors rebuild.
Examples are the gamma settings or the privacy screen parameters, that
emits an udev "hotplug" event when changed, but we want to register those
only when we handle the changed property.

The way wl_seat capabilities work, by notifying clients of capabilities
changes, and clients consequently requesting the relevant interface
objects (pointer, keyboard, touch) is inherently racy.
On quick VT changes for example, capabilities on the seat will be added
and removed, and by the time the client receives the capability change
notification and requests the relevant keyboard, pointer or touch,
another VT switch might have occurred and the wl_pointer, wl_keyboard or
wl_touch already destroyed, leading to a protocol error which kills the
client.
To avoid this, create the objects when requested regardless of the
capabilities.

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.

When creating the configuration for the builtin monitor we try to get
the panel configuration for the builtin panel, but we don't proceed if
that monitor is currently inactive.
This is fine when adjusting an active configuration to the current
device rotation, but it isn't correct when we want to create a new
configuration based on another where the monitor is configured but not
yet enabled.
So, only find the panel configuration without looking the current state
but ensuring that the passed configuration will enable it.

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.

Currently the only way to get cgroup for a MetaWindow is to get it's

The creation and access of this GFile is handled by

We fetch a frame clock that we schedule update on when queuing
_NET_WM_FRAME_DRAWN events. In some situations this frame clock is the
one from the stage, and if there are multiple hotplugs in a row, we
failed to update it as there were no stage views changes on the window
actor itself. As an actor updates the stage views list on layout, When a
queue_frame_drawn() call was done (typically from an X11 event) after a
second hotplug, it'd attempt to schedule an update on the frame clock
from the previous hotplug, as it didn't get notified about any
stage-views changes since for itself there was none.
Fix this by not caching the frame clock at all and just fetch it every
time.
In the majority of cases, this fetching means iterating over a very
short list (most often a single entry, rarely more), so it's very
unlikely to be of any relevance. The only situations where it might be a
heavier operation is the short time between a hotplug and a layout, as
it will attempt to traverse up to the stage to find a clock, but that's
likely only a few levels, so even that is unlikely to be an issue.

Currently, if g-r-d closes the read end of the pipe for a
SelectionRead() operation, due to realizing that the application, that
should provide the mime type content, does not provide any content,
mutter won't notice that and still assumes that the read() operation
on the pipe in g-r-d is still happening, as mutter never writes to the
pipe in that situation and therefore cannot realize that the pipe is
already closed.
The effect of this is, that if g-r-d aborts a read() operation and
requests a new read() operation via SelectionRead(), mutter will deny
the request since it assumes that the previous read() operation is
still ongoing.
Fix this behaviour by also checking the pipe fd in mutter before
denying a SelectionRead() request.

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).

We introduced META_MONITOR_SCALES_CONSTRAINT_NO_FRAC to get global scale

In fact it may happen that for some resolutions (such as 3200x1800) that
we did not compute some odd scaling levels (such as 3.0) but instead
its closest fractional value that allowed to get an integer resolution
(2.98507452 in this case).
Now this is something relevant when using fractional scaling because we
want to ensure that the returned value, when multiplied to the scaled
sizes, will produce an integer resolution, but it's not in global scale
mode where we don't use a scaled framebuffer.
So, take a short path when using no fractional mode and just return all
the applicable values without waste iterations on fractional values.

Since this tests the `--virtual-monitor` command line argument, it uses
the `MetaContextMain` variant of the context, as it's there that command
line argument is handled.

This object intends to replace the scattered functions that are used to
make up what is effectively a "mutter context". It takes care of the
command line arguments that is now done in main.c, persistant virtual
monitors, and the like.

The clutter tests neeed to start and stop, thus uses their own main loop
instead of the one in MetaContext. Shouldn't matter, since nothing
in mutter should happen that makes the test self-terminate from inside
mutter.

Users can add option entries, and it'll be part of the configuration
phase.
Create the main group manually to be able to set a user_data pointer;
this will be required to not have to rely on globals when parsing
options using a callback.

This intends to replace the call to `meta_register_with_session()` that
deals with X11 session management, and is called when the user is
"ready". In thet test context, doing that makes no sense, so make it a
no-op.

The start phase creates the MetaDisplay object, and initializes Wayland, and
creates the main loop.
The run phase runs the main loop and handles returning an error if the
context was terminated with an error.
The terminate phase terminates the main loop, with or without an error.

Configuration is the first step of the lifetime of a context, after
creation; it's here where argc/argv is processed, and it's determined
what kind of compositor, etc, it is going to be.
The tests always run as Wayand compositors, so the configuration is
quite simple, but will involve more steps later on.

It'll be part of and owned by MetaContext, intending to replace
`meta_is_wayland_compositor()`, but place it in a new file for public
enums so that it can be used from wherever.

This introduces a MetaContext implementation aimed to be used for test
cases, with as little boiler plate as possible needed in the test.
It currently doesn't do anything, just fills out the GObject boiler
plate and sets a name.
Build it into every core test, for compilation, even though it isn't
used anywhere yet.

This type is intended to replace the scattered functions used to
configure how the Mutter compositor is run. It currently doesn't do
anything, and only has a human readable name, intended to be set to e.g.
"GNOME Shell".
It's an abstract type, and is intended to be used via either a future
`MetaContextMain` for real display server use cases, and a
`MetaContextTest` for test cases.

Scanout doesn't go through the usual path of compositing and doing
eglSwapBuffers, therefore it doesn't hit the timestamp query placed in
that path. Instead, get the timings by binding the scanout buffer to an
FBO and doing a timestamp query on the FBO.

In order to make it possible to e.g. unload an unused DRM device, we
need to make sure that we don't keep the file descriptor open if we
don't need it; otherwise we block anyone from unloading the
corresponding module.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1828>
The DRM buffers aren't really tied to mode setting, so they shouldn't
need to have an associated mode setting device. Now that we have a
device file level object that can fill this role, port over
MetaDrmBuffer and friends away from MetaKmsDevice to MetaDeviceFile.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1828>
Keep a private MetaDeviceFile instance for the GPU's managed by the
renderer. This is a step towards decoupling rendering from mode setting,
as well as on-demand holding of device file descriptors.

Tags are meant to make it possible for a device file opener to tag a
file if it has affected the state the file descriptor is in; e.g. if it
has enabled a DRM capability.

Handle open() failing due to being interrupted by trying again until it
either succeeds, or fails due to some other error. This was an error
handling path taken when opening sysfs files; do the same here to not
potentially regress once we open sysfs files with the device pool.

It's only when we take/release from/to logind we need these two
integers, so only retrieve them when that's done. Making this change
makes it possible to open devices that don't have these parameters.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1828>
This changes the way the KMS backends load; if we're headless, we always
use the dummy one and fail otherwise; in other cases, we first try the
atomic backend, and if that fails, fall back on the simple one.
The aim for this is to have the impl device open and close the device
when needed, using the device pool directly.
