Using one variable to initialize all gestures will update the address of
the "gesture" pointer with every newly initialized object. This means
that event handlers which also use the "gesture" pointer like the
'keyboard-visible-changed' handler will update a different gesture as
soon as the pointer is changed.
This lead to a bug where the handler of 'keyboard-visible-changed'
wrongly nabled the unfullscreen gesture. Fix that by assigning each
gesture its own variable.

Since commit 520cea9394, the opacity of icon grid children is used
both to skip children outside the current viewport and to hide the
real icons while animating icon clones.
As a result, a grid animation during an animation now ends up showing the
icons that are being animated. Avoid that glitch by leaving children's
opacity alone when there's an ongoing animation.

AllView's adaptToSize is called as part of viewStack allocation vfunc, and this
makes the adjustment value to be reset while relayouting.
So, fix this by delaying this using the Meta later that we already had for
pageIndicators operations.
Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1392
Since the repositioning is now done during allocation, we can just queue
a relayout when setting the boxpointer positioning via the source actor.
As per this _relayout() and _updateFlip now needs to be called during allocation
only and with an allocation box set.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/576
Changing the arrow side might need to reposition the boxpointer, however
if this happens during allocation, we don't need to trigger a new relayout since
we'd set the new allocation once _updateFlip's _reposition call is terminated,
otherwise if the position has changed, changing the boxpointer coordinates
will trigger a relayout anyways.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/576
As per commit 044572cb60 boxpointer uses its own coordinates to position itself.
However this would lead to warning when mutter-clutter is compiled with debug
options as we'd might try to set the box coordinates during the allocation
cycle.
So, when calling _reposition during allocation, instead of setting the actor's
coordinates we just pass the allocation box and we adjust its origin, in order
to set it properly in the vfunc.

Hiding a child implies a parent reallocation, and IconGrid does it for the
children that doesn't fit in the available space, but this could lead to an
allocation recursion cycle. This has been introduced by commit 0e0574a0 to
reduce CPU usage not to using JS vfuncs.
To avoid this, toggle the children opacity instead so that we can achieve the
same visibility result, without any reallocation need.
In this way we also fix the case where hidden children can be shown again,
as _getVisibleChildren doesn't filter-out transparent ones, restoring the
pre-commit 0e0574a0 behavior.

Background is monitoring the whole `org.gnome.desktop.background` gsettings keys
for changes connecting to the non-specialized 'changed' signal and re-emitting
this as-is.
This means that when the background is changed via control-center, we get
multiple 'changed' signal events from GSettings, and for each one of this we
recreate a Background and a BackgroundActor.
Avoid this by using an idle to delay the emission of the 'changed' signal
grouping the events.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/558
The same Meta.Background could be used by multiple instances of background
actors, and so should not be disposed when the actor using it is destroyed.
Instead of calling `run_dispose` directly on it, just nullify the reference
on destroy method, leaving the job of doing the proper disposition to the
gabage collector that keeps the proper reference count on the Meta.Background.

The `switch-to-application-n` shortcuts are essentially "launch the nth
app in the dash" actions, so they are at the very least confusing when
the dash isn't available because the overview itself is disabled (for
example in initial-setup mode).
So disable the shortcuts when the overview is disabled, but delegate the
decision to a separate function so that extensions like 'panel-favorites'
which expose favorites by some other means can easily re-enable them.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1333
A menu item activation might lead to a call to `itemActivated` which eventually
will close the menu which leads to a `PopupMenu.removeAll` that destroys all the
items, stopping the emission of the 'activate' signal for them.
Before commit 4258ae3e this was not happening because destroy'ing a javascript
object wasn't really disposing it and thus stopping the signal emissions.
So, ensure that `itemActivated` is called after that all the other callbacks
have been consumed, and so that the menu is closed as last thing.

Upon construction of the CDMA modem proxy, _reloadCdmaOperatorName()
is called and the value of the Sid property is read.
That property is defined as UINT32 in the D-Bus interface, but the
value may not be loaded yet after the proxy is constructed, in which
case its value will be null.
In _findProviderForSid(), we'll end up calling lookup_cdma_sid(null)
which fails with the following assertion:
gnome-shell[1082]: nma_mobile_providers_database_lookup_cdma_sid: assertion 'sid > 0' failed
This commit changes the (sid == 0) check in _findProviderForSid()
to (!sid) which will also catch the null case.

The 'destroy' signal is emitted at the end of the destroy() method.
However the implementation of destroy() can end up emitting one of the
signals we connect to on the window, causing us to re-enter destroy
from its callback.
That will in turn lead to some objects getting disposed twice, which
produces a stack trace like the following one.
This commit fixes the issue by overriding the destroy() method instead
of connecting to the signal, which allows us to disconnect the signal
handlers from the window at an earlier time and avoid re-entrancy.

- Whether to use a PIM [2].
- Whether to use keyfiles. Unfortunately, GMountOperation doesn't

The interface name when a device is added may not be the final one. For
example when using USB tethering, it will first appear as 'usb0' before
being renamed to something like 'enp0s20f0u1' depending on the port the
phone is plugged in.
As a result, we will ignore the new interface name in that case and fail
to associate the correct connection with the device: Instead of the
correct "USB Ethernet" (or user-customized name), it will show up as
"Ethernet".

If an actor's allocation is outdated, clutter_actor_get_allocation_box()

Using the :allocation property (which may be outdated) would be better,

We currently assume that every location has an associated timezone.
While this is sound in the real world, in practise it depends on
whether or not libgweather can find a corresponding timezone DB
entry.
This used to be a fringe case, but has become more likely when commit
https://gitlab.gnome.org/GNOME/libgweather/commit/d7682676ac9 moved
weather stations from cities to countries - the station itself is un-
likely to have a timezone entry, and the country may be part of more
than a single timezone.
It would be good for libgweather to return a timezone for those
locations again, but we should defend against the case anyway.
We cannot tell what time it is at a particular location without
knowing the timezone, so simply filter them out.

The top bar handles allocating all its children itself, so there's
little value in chaining up to st_widget_allocate() and get the
default layout manager allocating all children again (and possibly

If this happens, we end up with an infinite allocation cycle with
corresponding performance penalty. Fix this by just doing and what
Shell.GenericContainer did before commit 286ffbe2b6 replaced it,
and not chain up to StWidget.

On one hand, we were using a path instead of an URI on
rsvg_handle_set_base_uri(). This broke at some point in librsvg
(presumably for the best, handling paths there sounds non-standard)
leaving a blank svg (As the base image wouldn't be accessed).
On the other hand, we use this with the deprecated rsvg_handle_write()
which we should drift away from.
Using rsvg_handle_new_from_stream_sync() neatly solves both. We use
newer API based on input streams and GFiles, and it internally does
the right thing, bringing the pad OSD back to life.

It may not be immediately obvious that the windows section is a

We currently copy the app icon menu behavior, which puts a separator

Work around a known regression from [1] that caused the volume bar in
the OSD window to never be hidden, even if the volume is set to 0. This
happened because the border radius of the barLevel is always drawn
without ensuring that the actual bar is visible.
So simply check if the value to draw is 0, and if it is, don't draw the
border radius of the bar at all. This will still result in incorrect
representation of values that have a width smaller than 2*border-radius,
but at least the bar looks right for a width of 0 now.

If a window gets destroyed right before it's resize

When determining the biggest icon size that fits the available height,
we first subtract the additional space requirements of icons (spacing,
padding, running indicator etc.) and then divide the result by the
number of icons to get the maximum size available to each icon texture.
In the above, the additional space requirement of each icon is taken
from the first icon (as all icons are assumed to be the same), and
calculated as the difference between the icon button's preferred height
and the currently used icon size.
To make sure that the icon is actually using the dash's current icon
size (even while animating to a new icon size), we enforce its height
during the size request and restore its original height afterwards.
However after some recent changes, that step is causing troubles:
For some reason, the original height may be 0, and when we restore it,
we end up forcing a fixed non-height that bypasses the regular size
request machinery.
While it is unclear where exactly the zero height comes from (maybe
waiting for a valid resource scale?), it is clear that it's best
to avoid forcing a fixed height. So instead of making the icon
texture comply with the assumed icon size, adjust the calculations
to use its current height request.

We recently added offsets to world clocks that represent the location's
timezone as UTC offset. However for most users, that representation is
overly technical and less helpful than the difference to their local time.

We currently use the city name for all location except named timezones.
However locations only have a city name if they are of level CITY or
DETACHED, or if they are of level WEATHER_STATION with a parent of level
CITY.
So when libgweather commit d7682676ac9 moved weather station locations from
cities to countries, it broke their names in the world clocks section.
To fix this, stop making assumptions about when we can use the city name
and simply try it first for all locations and fall back to the plain name
if its not available.

Currently all the widgets using BoxPointer and so popup actors are always drawn
at screen origin and then shifted at paint time in the proper position.
This doesn't work when using resource scale, since the widgets need to know
in which monitor they currently are in order to use properly scaled resources.
So, basically revert commit 22c22e0d7 and go back using the actual actor
coordinates for positioning and the actor translation for animating it, as the
relayouting issues of the past seem to be gone now.

Inserting a workspace is implemented by appending a new workspace, then
shifting all windows after the "new" workspace up. This has an unintended
side effect on sticky windows, as changing its workspace will unstick it.
Fix this by excluding sticky windows - there's little point in moving them
anyway, given that they should be on all workspaces (including the original
workspace and the target one).

The monitor index is not something that gnome-shell and
gnome-settings-daemon seem to be agreeing about. Using the connector
string is a much more reliable method of identifying a specific screen
and we are indeed using this already for monitor labling.
So switch over to use the connector rather than the monitor index. If a
user tries to use the old API, then the OSD will simply show up on all
monitors (which is the status quo currently anyway).

Now that the existing touch/touchpad gestures in windowManager only
handle normal mode, add corresponding gestures for the overview and
hook them up to the existing workspace scroll animations.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/516
The window group is hidden while in overview, so the stick-to-content
animation isn't visible either. Worse, the gestures messes up the
position of window actors in that case. Just limit the gesture to
normal mode for now, we will soon add it back in the overview with
its own animation handling.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/516
The touch/touchpad gestures to switch workspace currently hard-code
the modes in which we want the gestures to work. While these modes
are correct, the existing switch animation only works in NORMAL mode,
not in the overview where the window group is hidden. The easiest way
to address this is to handle both cases completely separately, namely
use separate actions in- and outside the overview.
Make the existing usable in that way by making the list of allowed
modes a constructor parameter.

ClutterContent's get_preferred_size should return a boolean weather the
preferred size is valid, so in javascript we've to return this state value

the returned height (that was then defaulted to 0)

NetworkManager added support for a new device - NMDeviceWifiP2P - but

This should ultimately be fixed in libnm, but as errors when adding
one device shouldn't interfere with adding any other devices, catching
exception is a good idea anyway, so do just that.

Commit 1b169655ac removed the system indicator from the list of children

width either, so if extensions add additional buttons, the menu is
likely to overflow.
Avoid this by only adding the button group to the list of size children.

This call just went through stomping over previous drag operations if any,
_maybeStartDrag() accounted for this, but other callers (well, WindowClone

This broke shell state by preserving connected captured-event handlers if
one tried to drag multiple windows simultaneously through multitouch. We
of course don't support that, now more elegantly.

The bind constraint that replaced the Shell.GenericContainer in commit
f4682748fa is subtly different from the previous code:
It forces the actor to have the same size as the stage, rather than just
requesting that size.
This breaks the magnifier which relies on the UI being able to be bigger
than the display size. Fix by going back to using a custom actor.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/646
The texture cache now returns an actor with an appropriate ClutterContent
rather than a ClutterTexture. That actor uses the CONTENT_SIZE request

Fix this by making sure the image is already loaded with the desired
dimensions.

Commit 8f15193b4 changed the `policy` property from a regular JS property to

Instead of just passing a scale when getting a cached icon, pass both a
'paint_scale', the scale of which the icon will be painted on the
stage, and a 'resource_scale', the scale of the resource used for
painting.
In effect, the texture size will use the scale 'paint_scale * resource_scale'
in a ceiled value while the size of the actor will use 'paint_scale' when
determining the size.
this would load a bigger texture, but the downscaling would keep the visual
quality.

If the user's real name is too long to fit the menu comfortably, we are
supposed to use the username instead. However since commit f8e5e3e435,
we no longer set a max-width on the menu as a whole, but instead base

the system menu ended up there, so the name is now allowed to grow
indefinitely.
Remove it from the list of size children to get the intended behavior
back.

The menu grabs the key focus when opened, which takes focus away from
whichever actor triggered the keyboard. And as the menu doesn't have
any text entries, the keyboard is popped down as a result.
Prevent this by making the menu items unfocusable, so the keyboard
focus just stays where it is. Considering that the menu is part
of the on-screen keyboard itself, not being keyboard-navigatable
isn't a big deal here.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/171
Menu items use a single 'active' state that follows both hover and
keyboard focus. It therefore makes sense for the active item to always
grab the focus, in particular as an item that is sensitive but not
focusable by keynav would be rather weird.
As it turns out, we do have a case that is weird enough where we want
exactly that, so only grab focus if the actor's :can-focus property
allows it.

The GtkSettings was originally introduced to inform applications about

Certain keybindings should continue to work even when a popup
menu is on screen. For instance, the keybinding for showing
the app menu and the keyinding for showing the calendar are
examples.
This is achieved by putting in place a special "POPUP" action
mode, whenever a popup menu is active. This mode replaces
the (e.g., "NORMAL" or "OVERVIEW") action mode that was in place
for as long as the popup menu is active.
But those keybindings should not work when the user is at the
unlock dialog (which uses an action mode of "UNLOCK").
Unfortunately, since commit c79d24b6 they do.
This commit addresses the problem by forcing the action mode
to NONE at the unlock screen when popups are visible.

This keyboard works similar to GTK+'s emoji chooser (actually, both pull
from the same JSON file). Emojis are categorized in sections and variants
and kept in a "model".
The EmojiPager actor then uses this model to generate pages on-the-fly as
the user swipes around. This is an important optimization since the amount
of actors would rival with the rest of the shell otherwise.
The EmojiSelection object puts the EmojiPager, the page indicators and
a KeyContainer with the bottom row of emoji section shortcuts together to
implement the emoji panel as a whole.
The Keyboard object hooked this to an "emoji" key, which is just visible
on the Clutter.InputContentPurpose where showing an emoji would be
meaningful. Otherwise the surrounding buttons are made a bit wider to
cover up for it (i.e. as it was before).
In order to cater for emoji panel usage, we want something like PageIndicators
except:
- It should have horizontal disposition
- It should not be animatable (?)
- It should not be reactive
Separated PageIndicators into a base, non-animated widget, and an
AnimatedPageIndicators that can be used on appDisplay.js. Reactiveness is
set through an extra method, and layout is set as a construct argument.
This will be useful as we want other panels (eg. emoji) to preserve aspect
ratio with the rest of the OSK. Separate the aspect ratio management logic
into this container that will be the parent of them all.
Since commit 447bf55e45 we turn the top bar translucent when

This is actually papering over bugs in toolkits. On X11 the Xserver will
send crossing events when the stage input shape changes. As those go

Besides the device grab on the drag device, also set up a captured-event
handler to catch other devices (except the keyboard) while the DnD
operation is ongoing. This makes DnD operations exclusive to others.
Also, disallow it in less aggressive ways if maybeStartDrag() gets called
while there is a current draggable.
This might definitely be nicer (eg. having other grabbed devices emit
leave/end events), but can't be done without major surgery to Clutter.
In the case where the draggable has an actor of its own, state could be
left broken when dragging on a place that would not accept the DnD op.
After button release, drag state is set to "cancelled" and the animation
begins. After the animation is finished, the drag actor would be destroyed
before disconnecting from its destroy handler.
Within the destroy handler, the grab would be undone but drag state would
be left on "cancelled" state for subsequent operations. This results in
DnD oddities and stuck grabs.
In order to fix this, double check in the actor destroy handler that we
are actually dragging before setting the "cancelled" state.
