In the synchronized subsurface case, the destination list may
contain other elements from previous wl_surface.commit calls.
Resetting the list will leave those dangling frame callbacks
that will lead to invalid writes when those get to be destroyed
(eg. on client shutdown).
The ResetIdletime API can be used instead of an "XTest" binary to
programmatically reset the idle time, as if the user pressed a button on
a keyboard.
This is necessary since we stopped using the XSync extension to monitor
idletimes, as it didn't consider inhibitors as busy, and mutter's
clutter code ignores "Core Events" as generated by XTest.
This patch will require minimal changes to gnome-settings-daemon's power
test suite so that "key press" idletime resets are triggered through
this D-Bus interface rather than through XTest and a roundtrip through
the X server.

Take idle inhibitions into account for when to fire idle watches as
requested by OS components.
This should stop gnome-session and gnome-settings-daemon considering
the session idle when they have been inhibited for longer than their
timeout, for example to avoid the screensaver activating, or the
computer suspending after watching a film.
https://bugzilla.gnome.org/show_bug.cgi?id=705942
Now that we've removed the X11 specific backend of the idle monitor,
add back a cut-down version of it for the explicit purpose of being
told about idle time resets when XTest events are used.
XTest events are usually used by test suites and remote display software
to inject events into an X11 session. We should consider somebody moving
the mouse remotely to be just as "active" as somebody moving it locally.
https://bugzilla.gnome.org/show_bug.cgi?id=705942
And use the old "native" backend for both X11 and Wayland. This will
allow us to share fixes between implementations without having to delve
into the XSync X11 extension code.

When moving the pending state of an effectively synchronized subsurface
so it is applied together with the parent, perform a merge of the source
MetaWaylandPendingState into the destination one, instead of simply
overwriting the struct.
The other approach had 2 kind of leaks, one that would happen everytime
a wl_surface.commit happens on a sync subsurface (both surface/buffer
damage regions are leaked). The other more unlikely one would apply on
the rest of pending state data, happening whenever the compositor gets
>1 wl_surface.commit calls on the subsurface before the parent surface
gets its own.
The function has also been renamed to use the more descriptive "merge"
term.

Output ID is set equal to 'i' later in the loop. But 'i' was never
incremented, so all outputs were getting the same ID (equal to
the number of CRTCs, because 'i' was reused from the previous loop).

Rendering the next frame (which mostly happens as part of the flush done
in swap buffers) is a task that the GPU can complete independently of
the CPU having to wait for previous page flips. So reverse their order
to get the GPU started earlier, with the aim of greater GPU-CPU
parallelism.
(cherry picked from commit 6e415353e3)
Mutter recently gained the ability to deal with multiple GPUs
rendering at different displays. These GPUs would have a display
connected to them, and Mutter was adapted in order to be aware
of different GPUs and their outputs.
However, one specific edge case appeared: PRIME systems. PRIME
systems have two GPUs:
* The integrated GPU (iGPU), usually Intel, which has connectors
and deals with the routine load.
* The dedicated GPU (dGPU), usually AMD or NVidia, which has no
connectors at all and are there just to aid heavy loads.
On those systems, the dGPU is aggressively put to sleep by the
kernel to avoid energy waste. Waking it up is a costly operation.
With Mutter's adaptation to deal with multiple GPUs, Mutter began
wakening the dGPU every time some rendering had to be done. This
was causing stuttering every time the dGPU was put to sleep, and
Mutter asked it to wake up again.
To fix this situation, this commit ignores GPUs with no connectors
attached.

This is a small mistake spotted while working on a solution

This state tracks hardware devices' state, thus shouldn't be triggered by

Raising and lowering windows in tandem without a proper grouping
mechanism ended up being more annoying than functional.
This reverts commit e76a0f564c.
We just arbitrarily chose the first EGL config matching the passed

When painting the titlebar, button icons that aren't available in the
desired size need to be scaled. However the current code inverses the
scale factor, with the result that the adjusted icons are much worse
than the original icons, whoops.
This went unnoticed for a long time given that most icons are availa-
ble in the desired 16x16 size, and the most likely exceptions - window
icons - are not shown by default.

In order to let applications gracefully handle version mismatches, add
a version property to the APIs. Also add a warning on the APIs that
these are not meant for public consumption.
If the coordinates was for a stream not at the stage position (0, 0),
they'd be incorrect. Fix this by correctly translating the coordinates
according to the stream position.
Make the Wayland objects push the state relevant to their role to the
MetaSurfaceActor instead of MetaSurfaceActorWayland pulling the state
from the associated surface.
This makes the relationship between the actor and the objects that
constructs it more clear; the actor is a drawable that the protocol
objects control, not the other way around.
This will make it easier to "detach" a surface actor from a surface,
which is necessary when unmapping a window while the underlying surface
is yet to be destroyed and potentially reused.

This commit moves out non-core wl_surface related code into separate
code units, while renaming types to fit a common scheme. The changes
done are:
* ClutterActor based surface roles built upon
MetaWalyandSurfaceRoleActorSurface. This object has been renamed to
MetaWaylandActorSurface and related functionality has moved into
meta-wayland-actor-surface.c.
* The code related to roles backed by a MetaWindow (i.e. built upon
MetaWaylandShellSurface) was moved into meta-wayland-shell-surface.c
* The majority of subsurface related code was moved into into
meta-wayland-subsurface.c and the object was renamed
MetaWaylandSubsurface.

mutter would discard the shape region set by the client if its matches
the entire client area in meta_window_x11_update_shape_region().
However, if the window is later resized (maximized or other), the
compositor will fail to update the shape region properly for undecorated
windows because the shape region was discarded, which causes black areas
to appear in place of the updated areas.
If the client window is undecorated, keep the shape region even if when
it matches the client area.

When the buffer modifier is DRM_FORMAT_MOD_LINEAR, we can use the
old code path. That means not specifying any modifier parameter.
It was an issue when the primary GPU was creating a linear GBM surface
and that a secondary GPU (not supporting modifiers) was trying to
import it. It was failing because the driver could not use the
import_modifiers extension even though it could in theory easily
import the buffer.

We were retrieving the supported KMS modifiers for all GPUs even
though what we really need to intersect between these sets of
modifiers:
1) KMS supported modifiers for primary GPU if the GPU is used for
scanout;
2) EGL supported modifiers for secondary GPUs (different than the
primary GPU used for rendering);
3) GBM supported modifiers when creating the surface (already
taken care of by gbm_surface_create_with_modifiers());

If text_input_enable() is called when there no active IM (eg. running plain
mutter), some ClutterInputFocus method calls that are not allowed while
unfocused will end up called, triggering critical warnings.
If there is no IM return early here, all other calls are superfluous then.
We currently don't handle NULLs on these correctly, yet they can be
so when running nested. Just refrain from sending those wp_tablet(_pad)
events in that case.
The property has been 32 bits since around 2011 and has not changed, mutter
expects it to be 8 bits. The mismatch causes change_property to never
actually change the property.

Plain input stream read() calls don't provide hard guarantees about
the number of bytes read, but the async method callback sort of
relies on bytes being less than requested only when reaching the
end of the transmitted data. If that happens mid transfer, that
doesn't bode well.
This is actually the behavior of g_input_stream_read_all(), so
switch to using it.
This was done by the clutter X11 backend before prior to introducing
MetaRenderer, but during that work, enabling of said extension was lost.

If for whatever reason, there are stalled files in /tmp/.X11-unix/ the
bind() to the abstract socket will succeed but not the bind() to the

This causes gnome-shell/mutter to fail because it cannot start Xwayland

In case of failure to bind to the UNIX socket, try the next display
instead of failing, to avoid stalled entries in /tmp/.X11-unix.

The shortcut inhibitor protocol states that the “active” event should be
sent every time compositor shortcuts are inhibited on behalf of the
surface.
However, mutter would send that event only if the surface is focused,
which might not be the case if focus is on a shell surface.
Send the “active” event unconditionally to match the protocol
definition.

There seems to be a kernel race when one disconnects an external
monitor connected to a DisplayPort via a USB-C adapter. The race
results in a connector being reported as connected, but without any
modes supported.
This had the side effect that we tried to set a preferred mode to
the first listed mode, but as no modes were available, we instead tried
to dereference the first element of a NULL array, causing a
segmentation fault.
Mitigate this by skipping adding output if no supported modes are
advertised and the output doesn't support scaling, while moving the
fallback path for calculating a preferred output mode to after possibly
adding the common modes, to avoid the unvolentary NULL dereference.

Opening and closing the device may result into XI2 grabs being cut short,
resulting into pad buttons being rendered ineffective, and other possible
misbehaviors. This is an XInput flaw that fell in the gap between XI1 and
XI2, and has no easy fix. It pays us for mixing both versions, I guess...
Work this around by keeping the XI1 XDevice attached to the
ClutterInputDevice, this way it will live long enough that this is not
a concern.

When a window's workspace is not NULL, on_all_workspace should be FALSE.
Similarly, when on_all_workspace is TRUE, the window workspace should be
NULL.
This is an assumption in multiple places in the code, including when
setting the workspace state, the window is either added or removed from
all workspaces only if the window's workspace is NULL.
This rule is initially enforced at creation in _meta_window_shared_new()
when a initial workspace is set. However, when the initial workspace is
set from the session info, the initial workspace is not marked as “set”
which leads to an assertion failure when unmanaging windows, because the
window is not removed from all the workspaces.
When applying the session info to a window, mark the workspace as “set”.
https://gitlab.gnome.org/GNOME/mutter/issues/4Closes: #4
Having “on_all_workspaces_requested” FALSE on a window does not imply a
workspace is set.
If the X11 window is placed on a secondary monitor while workspaces
applies on primary monitor only (“workspaces-only-on-primary” set) then
“on_all_workspaces_requested” is FALSE while “on_all_workspaces“ is TRUE
and the associated workspace is NULL, leading to a crash when saving the
gnome-shell/mutter session.
So if no workspace is set, use the “initial_workspace” instead to avoid
a NULL pointer dereference.

Now that we have the list of supported modifiers from the monitor
manager (via the CRTCs to the primary planes), we can use this to inform
EGL it can use those modifiers to allocate the GBM surface with. Doing
so allows us to use tiling and compression for our scanout surfaces.
This requires the Mesa commit in:
Mesa 10.3 (08264e5dad4df448e7718e782ad9077902089a07) or
Mesa 10.2.7 (55d28925e6109a4afd61f109e845a8a51bd17652).
Otherwise Mesa closes the fd behind our back and re-importing will fail.

Using 800x600 as minimum logical size is very 4:3 thinking, while a lot of
modern devices are 16:9. The specific reason for this commit is to allow
1.5 scaling at mini-laptops (clamshell devices) with e.g. a 5.5"
1280x720 screen. Given that this device has a keyboard, one obviously
is not holding it very close to ones eyes and at 220 dpi that means the text
is too small at scale 1.0. For one real world example of such a device see:
https://en.wikipedia.org/wiki/GPD_Winhttps://bugzilla.gnome.org/show_bug.cgi?id=792765
Offer the text-input interface global, so it can be used by clients. The
MetaWaylandSeat will also let MetaWaylandTextInput intercept key events
before the keyboard interface handles those.
This is the implementation of the internal text-input protocol that will
be used to communicate IMs (to be implemented by gnome-shell) with clients.
The text_input protocol has its own focus expressed through enter/leave
events, that will typically follow the keyboard's.
The client will be able to communicate its current status (eg. focus state,
cursor rectangle in surface coordinates, text surrounding the cursor
position, ...) and will receive commands from the compositor (eg. preedit
text, committing a string, ...).
Whenever there is an active input method, the compositor will route key
events directly through it. The client will not receive wl_keyboard
events if the event is consumed by the IM.
Issuing a shortcut inhibit request for a surface without a window set
will lead to a crash when trying to show the shortcut inhibitor dialog.
In such a case, it's safer to deny the request.
https://bugzilla.gnome.org/show_bug.cgi?id=792599
The events might fall through if there's no corresponding active
pointer/keyboard/touch interface. Barring bugs this should be safe to do,
just a bit wasteful.
When maximizing a window, the previous location is saved so that
un-maximize would restore the same original window location.
However, if a Wayland client starts with a window maximized, the
previous location will be 0x0, so if we have to force placement in
xdg_toplevel_set_maximized(), we should update the location as well so
that the window is placed on the right monitor when un-maximizing.
For that purpose, add a new flag to force the update of the window
location, and use that flag from xdg_toplevel_set_maximized().
https://bugzilla.gnome.org/show_bug.cgi?id=783901
Wayland clients know their size better, so for Wayland we'd rather not
try to resize the client on un-maximize, but for this to work we need a
new MetaMoveResizeFlags.
