Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.
This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:
* Repainting an offscreen actor is measurably slower than repainting
the same actor if it was uncached. But only by less than 100%,
so if an actor can avoid changing every frame then caching is usually
more efficient over that timeframe.
* The cached painting from a container typically includes its children,
so you can't cache containers whose children are usually animating at
full frame rate. That results in a performance loss.
This could be remedied in future by Clutter explicitly separating a
container's background painting from its child painting and always
caching the background (as StWidget tries to in some cases already).
So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:
One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)
Also a couple of bugs are fixed by this:

Instead of consuming the event in front of the input method. Enter
is sometimes overriden by those, so it seems better to let the IM
handle the key event, and react later to it if it got propagated
anyway. That is what ::activate does, so use this signal.
This used to work before ClutterInputMethod/InputFocus because the
IM received the events directly from stage captured events. This
is not the case anymore.
Closes: #440
We used to keep the workspace switcher slid out when the user made use
of workspaces. This was changed in commit 2d84975 to give more space
to window previews, but it turned out to make the switcher quite a lot
more difficult to interact with (rather than only being a question of
discoverability). So go back to the previous behavior.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/161
During global grabs, actors miss enter and leave events required
for correct hover tracking. This can cause the workspace switcher
to get stuck while slid out, so ensure the actor's hover state is
synced after drag operations.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/161
We show a cover pane on top of the overview during transitions to
prevent issues caused by clicks and mouseover events when the overview
is not ready. Right now, this pane is only being shown on the primary
monitor, which obviosly allows interactions to happen before the
animations are finished on the secondary monitors.
To fix this, use the size of the whole stage for the cover pane.
Emitting it that soon results in JS warnings, as we don't have
everything in place yet. The position-changed signal will be
emitted from other locations as soon as we have it.

When trying to close a window in the overview by clicking the close
button and the window doesn't get closed but a dialog is added to the
window afterwards, we close the overview and show the dialog.
Instead of adding a separate listener for the window-added signal to the
WindowOverlay, let the WindowClones remember that the close button was
pressed and activate themselves if a dialog is added after that.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/180
When a dialog is added to a window while the overview is shown, we get
its parent using get_transient_for() so we can add it to the right
window clone.
If we have multiple layers of dialogs we have to do this recursively
until we find the root ancestor. This case currently results in an
infinite loop: Since parent is always set to the same window, the
while-condition will always be true.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/180
For the OSD, all parameters except for the icon are optional - if the
caller doesn't include the 'label' option, the OSD won't show a label
etc.
While this makes sense for an API, it means that we have to be careful
to correctly differentiate an option that was omitted and an option
that has a 'falsy' value like false or 0.
Unfortunately since commit ccaae5d3c we no longer do, with the result
that OSDs meant for the first monitor will show up on all, and a level
of 0 is presented as no level bar instead of an empty one, whoops.

GSettings now recognizes per-desktop overrides that can be used
to change schemas' default values for a particular desktop. This
is not entirely unlike our existing custom override mechanism in
mutter, except that it is not limited to keys in org.gnome.mutter,
and it doesn't require a separate schema - the latter means that
we (and gnome-teak-tool) no longer have to figure out the correct
schema for the current login session and just use the original one.

Show an overamplified volume icon if volume is louder the max normalized one.
Use a similar logic as gnome-settings-daemon to delimit values, restricted
to output.
The purpose is to help users remember that visiting some websites or
using some apps can get LOUD.
https://bugzilla.gnome.org/show_bug.cgi?id=790280.
Implement for barLevel an overdrive area. This is a zone represented via a
different styling to indicate that you are bypassing the normal zone of
a given level, without reaching yet the maximum limit.
https://bugzilla.gnome.org/show_bug.cgi?id=790280.
Depending on hardware and recorded volume level, turning up the speakers
to the maximum volume may not be enough and the user will want to amplify
the volume above 100%. Currently this requires opening the sound Settings
panel which gets cumbersome when required repeatedly.
To support this case better, allow raising the sound volume above 100%
directly from the system menu if the feature is enabled via the
`allow-volume-above-100-percent` key in `org.gnome.desktop.sound`.
Allow osd representing levels that can be more than 100% by accepting
an optional parameter setting that maximum level.
gnome-settings-daemon will use this to indicate volume levels above 100%,
which our own volume indicator will soon support as well.
Ensure that both barLevel and slider can support a higher maxValue than 1
and computes various positions based on it.
It defaults to 1 if not set.
https://bugzilla.gnome.org/show_bug.cgi?id=790280.
Reuse the BarLevel class to get similar drawing behavior as Slider.
Rename theme css impacted properties and ensure that the osdWindow
remains accessible.
Ensure we don't force setting a custom border color like on the OSD.

In a9ad91c831, a bug was introduced in the following code:
```c
this._settingsAction.connect('clicked',
this._onSettingsClicked().bind(this));
```
Notice that the callback is being executed! This commit
fixes that by removing the '()' from the callback.
As strings are guaranteed to use UTF-8 in the GNOME platform, generic
file APIs like g_file_load_contents() return raw data instead. Since
gjs' recent update to mozjs60, this data is now returns as Uint8Array
which cannot simply be treated as string - its toString() method boils
down to arr.join(',') - so use gjs' new ByteArray module to explicitly
convert the data.

The settings action button in the system menu simply launches
gnome-control-center, so we want its icon (and accessible name)
to always match the app. So instead of keeping the button in-sync
with Settings, just look up that information from the app itself.

We can simply request the symbolic variant from CSS so that we don't
have to append '-symbolic' to all the names. This will always make

Commit e5c95b910d refactored the workspace animation to also handle
animations that involve all surrounding workspaces, but due to an
ill-advised review comment (guess whose) it broke the animation
for non-neighboring workspaces.
Update the code to handle correctly whether in a given direction:
- we have the target workspace of a given index
- we have a neighboring workspace
- we don't need to animate anything

Add a debug command (to be executed manually via Alt+F2) to check
that all of gnome-shell's file descriptors have the CLOEXEC flag set.
This is important so that internal file descriptors do not get passed
to apps when they are launched.
It prints a warning message for every fd that does not have the flag set.
fdwalk() is used from the standard library if available (it is not
available in glibc), otherwise we use the same implementation as glib
has internally.

When 4fg swipe motion happens, set up early the workspace switching
animation with all surrounding workspaces. This allows us to move
all content back and forth in any direction. This works on both
touchcreens and touchpads.
When the gesture is activated, the same data is reused to follow
up with the tween animation.
The threshold has been also doubled, it was fairly small to start
with, and feels better now that workspaces stick to fingers.
https://bugzilla.gnome.org/show_bug.cgi?id=788994
Besides the separation into distinct functions, the stored data has
been made able to generically store windows from all surrounding
workspaces. All while keeping a special mode to animate between two
workspaces (The usual till now), this is the only mode exercised so
far.
In order to ease animations, all window groups are now children of
a common container, which is then animated.
A custom callback type is more convenient, but only as long as no
other callback type is required. We are about to add functionality
that does not return the filename to a screenshot saved on disk, so
prepare for that by moving to GIO's generic async callback pattern.

Fullscreen windows cannot be restored by touch device users unless the
application adds support for it.
As it is unlikely to change all application lets introduce a top edge

Make the indicator for active remote access use the warning color, to
indicate the severity of allowing remote access.
This only makes the indicator icon orange; the icon in the system menu
is still white.
Add an indicator for when there is something access the display server
remotely. This could be 1) remote desktop, 2) screen cast or 3) remote
control, but all effectively applications using
org.freedesktop.portal.ScreenCast or org.gnome.portal.RemoteDesktop as
well as gnome-remote-desktop using the corresponding org.gnome.Mutter
APIs directly.
As it is now, it'll simply show a single icon for when anything is
having an active session, and a single action "Turn off" that'll close
every active session.

If we're started by systemd, we won't be in the user's display session.

For windows, the cursor location needs to be adjusted by the frame
offsets. However we cannot assume that there is a window, as the

Maximized and tiled windows can be restored with a drag gesture,
not only from their titlebars, but also from any non-reactive

If the Escape key is used for a window/app cycler/switcher shortcut
(such as "Switch windows directly"), then there is no way to cancel
the switching/cycling operation with the keyboard.
This change allows cancelling such an operation by pressing the Tab
key, but only if Tab is not already being used by the current
switcher/cycler shortcut.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/315
Key events involved in a keyboard shortcut are not completely consumed by
Mutter. That means that if the popupMenu is bound to a shortcut (e.g.
Alt<Space>) and the user keeps the keys pressed, the same key-event will be
delivered to the popupMenu. We can workaround this issue filtering out all the
events where a a modifier is down (except capslock).
Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/372
Destroying and recreating the entire events list on every change is not only
wasteful, it also breaks the clear functionality as messages scheduled for
removal are replaced with "new" messages after the first message has been
removed.
Address both issues by keeping track of all messages and re-use them
whenever possible.

And stop using FocusCaretTracker for caret position purposes. This
new object uses 1) the text-input protocol in wayland and 2) Info
from IBusPanelService for X11 (which is meant to work for XIM too).
This drops the usage of AtspiEventListener for OSK purposes, which
is best to avoid.
If a clone gets destroyed before the corresponding MetaWindow is
removed from the workspace, we will still find it in the list of

When middle-clicking an app icon on the Dash, it will always try to open
a new window of that app, even if the app doesn't support multiple
windows. Meanwhile, Ctrl+click on an app will only open a new window if
the app allows it.
This change prevents middle-clicks on app icons from opening new windows
for apps without multi-window support.

When the actor that has the key focus is destroyed, Clutter moves
the focus to the stage. In case the destroyed actor was inside a
ModalDialog, this breaks any keyboard interaction: keynav is broken
because the stage isn't in any focus chain, and access keys like
Escape because they are handled on the dialog's parent.
The only dialog that may destroy a child without recreating the dialog
buttons (and thus moving the key focus there) is the WirelessDialog,
fix it by keeping the key focus within the dialog when removing networks
from the list.

Just like we did for the window list in app icons' context menu,
provide a fallback for window captions in the window picker rather
than showing blank items to the user.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/26
The app icon's context menu contains a list of open windows,
identified by their title. As we currently don't handle the
case where the app didn't set a title, we end up with empty
menu items which looks clearly broken. Fall back to the app's
name in that case.

The close dialog for non-responding windows is closed automatically
when we detect that the window is responding again. However as we
currently only ping the window in response to certain user actions
(like focusing the window or opening the window menu), this can
easily go undetected.
Address this by periodically pinging the window while the close
dialog is shown.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/298
The dialog won't be visible when unredirection is in place (for example
while a fullscreen window is focused), so disable unredirection while

Similar to what it's done when the main connection changes, we need
to make sure that the icon in the panel gets updated before calling
_syncConnectivity(), so that the icon gets always updated if needed,
regardless of whether there's an active connection or not.
This is needed because there's at least one case when an icon should
be shown when the computer is not connected to any network: when a
hotspot has been enabled, which can be useful even if there's not
an internet connection to share (e.g. to easily allow connecting
other devices to the computer.

Commit f285f2c6 changed Scripting.createTestWindow() to accept a parameter
object instead of a parameter list but forgot to remove the width and height
arguments. This breaks the "core" test as all windows are created with default

We use the close() method to disconnect signal handlers set up in
init(), however the handler ID is only valid in the first call in

If we get an error during device enrollment, the message might be
prefixed to indicate that the error came from the remote peer. We
are presenting that message to the user so strip that prefix away
if it was there.
The devices emitted (device, error) while the connected handler
was expecting (error, device). The former is more consistent
with the rest of the code (so change it to device, error).
Modes, extensions and other GNOME Shell assets are searched in appropriate
subdirectories of each directory in XDG_DATA_DIRS, falling back
to global.datadir.
However, this isn't the case for themes, which are currently always expected
in global.datadir, even when referenced by a mode in a different XDG_DATA_DIR.
The fix is to have the theme finding pattern follow the same logic as other
elements.
Fixes#167.
The HIG discourages the use of icons in menus except for "noun" items

Since commit 1939e22c22, we move the keyboard focus with the hover

focus when the previous focus was already inside the window picker
or unset.

The original UTC support in GWeather piggy-backed on the existing API, but
as "country" or "city" don't make sense in the context of UTC or AoE, the
concept of "named timezones" was introduced. Handle those explicitly to get
back labels for those locations.

We don't toggle the overview if the request happens too close to the
last activation, to filter out double-clicks or activation by both
the hot corner and a click. However as the check is based on the
real time, the check breaks if the system clock moves backwards and
the last activations appears to be in the future. Fix this by using
monotonic time which is guaranteed to only move forward.

While polkit requests *should* be the result of a user action, that's
not always the case in practice and authentication dialogs can pop up
out of nowhere at any time. That's always annoying, but particularly
bad on the lock screen. If we disabled the polkit component altogether,
the fallback GTK-based agent would kick in, so instead handle the case
explicitly and postpone showing the dialog until the session is unlocked.
