The `reactive` property of icon actors was being restored multiple times
over the course of the pulse animation, all at slightly different times
as each icon finished animating at different times.
The problem is that toggling `reactive` on an `StWidget` incurs a style
change of the `insensitive` pseudo class, and style changes would quickly
queue relayouts incurring full stage reallocation. This occurred many times
during a pulse animation, limiting its smoothness and performance.
The solution is to not toggle the `reactive` property in the pulse
animation at all, which avoids incurring multiple full stage relayouts.
As a bonus, this means the icon under the cursor pulses with the correct
selection highlight, appearing more seamless and responsive.

The `reactive` property of icon actors was being restored 24 times over
the course of the spring animation, all at slightly different times as
each icon finished animating at different times.
The problem is that toggling `reactive` on an `StWidget` incurs a style
change of the `insensitive` pseudo class, and style changes would quickly
queue relayouts incurring full stage reallocation. This occurred many times
during a spring animation hogging the CPU and limiting the frame rate.
The solution is defer and batch the cleanup for all icons until after the
last icon has finished animating. This way the CPU impact of the style
change and stage relayout isn't felt during the animation so the frame
rate remains higher and smoother. The overall CPU usage of the animation
is also reduced as the remaining relayouts are much more likely to be
grouped into a single frame.
Icon spring animation performance on an i7-7700:
Before: 83% CPU and 47 FPS
After : 78% CPU and 54 FPS
which is about a 22% increase in performance per clock (FPS/CPU).

The switcher popup is a large, mostly transparent actor that
should cover all the clickable area of GNOME Shell. In Clutter
terms, it should cover the whole stage.
By binding it to the primary monitor, the Alt+Tab behavior
becomes a bit inconsistent. For example, by not hiding when
clicking at empty spaces at other monitors.
Fix that by binding the SwitcherPopup to the whole stage,
and not only the primary monitor.

If no password or a wrong password is entered after automounting an
encrypted device, then the password should be reasked. However, this
does not happen because the relevant udisks error messages for this
cases are missing in the exception handler that calls _reaskPassword.
Fix this issue by adding the relevant udisks error strings to the
exception handling in the _onVolumeMounted method.

Fix a regression causing the portal helper to crash.
In 94423151b2 we moved the dbus interface
descriptions into seperate files which is why we had to include the
fileUtils js module. This module imports the params js module, so add
params.js to the gresources file for the portal helper.
We currently only ignore minimized windows, not windows that are
hidden for other reasons - namely on wayland windows are initially
hidden until they are placed.
This fixes a flicker in the transparent top bar on wayland when the
"position" of an unplaced window wrongly suggests the window is
overlapping the top bar.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/693
Since we started to show OSD windows on all monitors, OSD windows are
destroyed when the corresponding monitor is disconnected. We shouldn't
leave any signal handlers around in that case - they prevent the object
from being garbage collected, and trigger warnings for accessing proper-
ties of invalidated GObjects.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/602
When maxLevel is > 100%, first OSD appearance was capping the current
level to 100%. Consecutives key press were then OK.
Ensure we setMaxLevel before setting Level itself, so that correct cap
value is applied.
App folder popups take a grab when opened, and as we don't pass any
particular pushModal() parameters, all keybindings are blocked. While
this makes sense for most keybindings that would interfere with the
popup interaction, others like volume/brightness keys or screenshots
can be allowed safely.

Add exception to handle a keypress if numlock is enabled as we already do for
capslock. This uses Clutter.ModifierType.MOD2_MASK because at the moment there
is not a more explicit way to refer to the numlock mask.

Instead of taking care of the PanelMenu.ButtonBox.container
destruction by itself, delegate that to the very object that
created it in the first place: PanelMenu.ButtonBox itself.
This is the last remaining usage of Shell.GenericContainer
in the codebase, and posed small challenges compared to the
other removals.
A new St.Widget subclass called InputSourceIndicatorContainer
was added as a replacement to the Shell.GenericContainer. It
was needed because GNOME Shell needs to override the regular
size allocation functions, but InputSourceIndicator already
is a St.Widget with its own size allocation overrides.

Because we're late in the cycle, and don't know how many
extensions actually rely on this API, this commit adds
back the BoxPointer.show() and .hide() functions, with
warning messages to notify consumers that this is going
to be removed.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Pretty much like dd4709bb2, BoxPointer's show() and hide()
functions will clash with Clutter.Actor's ones.
In addition to that, on a conceptual level, the current API
is not great, because calling boxPointer.hide() won't result
in boxPointer.actor.visible == false.
For these reasons, rename show() and hide() to open() and
close(). A compatibility layer will be added in a following
commit, warning about the usage of show() and hide().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
LayoutManager is currently a pure JavaScript class that
relies on the rudimentary Signals.addSignalMethods() to
handle signals. This is an inefficient implementation of
one of the most central classes in GNOME Shell.
In addition to removing Shell.GenericContainer, then,
turn LayoutManager into a proper GObject.Object subclass.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
In the next commit, we will turn PanelMenu.ButtonBox into a
St.Widget subclass. As a domino effect, PanelMenu.Button will
become one too, and so will Panel.AppMenuButton.
When that happens, the current show() and hide() functions in
Panel.AppMenuButton will clash with Clutter.Actor's ones.
To avoid that, rename these functions to fadeIn() and fadeOut()
and avoid a name clash.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
This is another straight port from Shell.GenericContainer.
The important thing to notice is that the calculation is
broken if the StThemeNode helpers (adjust_preferred_* and
adjust_for_*) aren't used.
The downside of this patch is that it removed the skip_paint
from the thumbnails. Keeping it would add an unecessarily
large amount of code.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Removing Shell.GenericContainer from the IconGrid class was
challenging because it needs the "skip paint" API from it.
This API was added, too, as a workaround to the inability
to override vfuncs from GJS.
The overrides are largely copy-pasted and translated versions
of the Shell.GenericContainer code.
The IconGrid:key-focus-in signal was renamed to :child-focused
to avoid clashing with ClutterActor:key-focus-in.
In GridSearchResults, the internal IconGrid had it's y_expand
set to false, so it doesn't push other search elements (the
list results mainly) to the bottom of the screen.
Because skip paint wasn't and still isn't a GObject property,
rename it to _skipPaint to reflect that.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
As part of our quest to obsolete Shell.GenericContainer, IconGrid will
become a Clutter.Actor subclass. As the ::key-focus-in signal would
clash with Clutter.Actor::key-focus-in, rename it to ::child-focused.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
DashItemContainer currently animates the scale and opacity
of its child when zooming in. This is visible when adding
a new favorite item to the dash; the items will zoom in from
the center.
After the previous commit, however, the zoom animation got
slightly broken, and looked like the icon was coming from
the bottom instead of the center.
Fix that by setting the scale and opacity of DashItemContainer
itself, instead of its child. Remove the unused code after that
too.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Pretty much like the previous patches, this extends St.Bin. The
most interesting aspect of this patch is that most of the sizing
routines of the icons is now delegated to the actors and layout
managers, removing quite a bunch of code.
The 'spacing' theme property is now redirected to StBoxLayout's
spacing property. Also adjust the Dash code to stop forcing a
potentially invalid width in the first icon too.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
This commit removes all the uses of Shell.GenericContainer from
SwitcherPopup.SwitcherList. Compared to the other patches, this
one was specially trickier to get right, and a few invasive
changes needed to be done.
The most noticeable one is that the allocation of the items is
done entirely by St.BoxLayout -- we don't manually allocate them
anymore. To make it work, get_preferred_width() had to calculate
the correct value. It now assumes that:
* Minimum width: the minimum width of the widest child.
* Natural width: the minimum width of the StBoxLayout (use it
instead of the natural width to force the labels to ellipsize
when too long.)
The AppIcon class became a St.Widget subclass as well, to override
get_preferred_width() and be able to keep the squared shape.
Besides that, add a new SwitcherButton class to reimplement squared
icons without having to resort to hacks in the size allocation
machinery. This class has a single vfunc override to ensure that it
is squared when the SwitcherList is.
The arrows indicating multiple windows are now in this._list
actor to the SwitcherPopup itself, since this._list automatically
manages its own children now.
At last, adapt (but preserve) the hack in CyclerPopup.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Instead of overriding vfunc_get_preferred_width|height(), use the
already available Layout.MonitorConstraint to bind SwitcherPopup
to the primary monitor.
This commit turns SwitcherPopup.SwitcherPopup into a St.Widget
subclass, and gets rid of Shell.GenericContainer usage. Subclasses
were adapted to that too.
This class introduced a new challenge: it overrides show(). As per
discussions, we now call this.visible = true inside show().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
In the process of purging all usages of Shell.GenericContainer
of GNOME Shell, one specific problematic situation that might
occur is when classes have functions that would clash with any
ClutterActor or StWidget function name.
One of such example is SwitcherPopup.destroy(). Right now, this
class is a pure JavaScript class that wraps a real actor, but
soon this will change, and it'll become a St.Widget subclass.
Another problem with functions that mimic the toolkit ones is
the predictability of them; after calling destroy(), that widget
is expected to not be available anymore. In SwitcherPopup case,
it is still available for a short while. In this case, that's not
a big problem, but the show() and hide() functions in other clases
are more problematic because the actor's visibility does not
follow that.
This commit is a first step in cleaning that up, and changes the
SwitcherPopup.destroy() to fadeAndDestroy().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Shell.GenericContainer exposes the size negotiation machinery
through the use of signals. Signals are not specially performant.
One of the reasons is that they acquire a global lock for signal
handlers lookup. GNOME Shell has more than 2,000 actors at any
given point in time, up to 20 levels deep in hierarchy, making
size negotiation and painting non-trivial tasks. Such a critical
section of Clutter's machinery shouldn't rely on signals
whatsoever.
Regardless of that, Shell.GenericContainer is a workaround to
a non-existing issue anymore. It shouldn't be used anyway, and
any performance improvements that removing it can potentially
yield are bonuses to it.
This commit starts this work by removing Shell.GenericContainer
usage from Panel.Panel class. The class now extends St.Widget,
and as such, it has no "this.actor" field set anymore. A couple
of places where this actor field was used are adjuste as well.
It is important to notice that we now allocate the Panel itself
inside vfunc_allocate(). This was previously done before emitting
the signal by Shell.GenericContainer.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
ClutterVirtualInputDevice has the limitation that event flags won't be
made to contain CLUTTER_EVENT_FLAG_INPUT_METHOD, possibly causing feedback
loops.
As the event gets injected up the platform dependent bits, we can avoid
care on not pressing the same key twice, we still expect coherence between
key presses and releases from the IM though.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/531
When adding a favorite, we add the ID to the list of favorites, save the
setting and add the new app to the favorites map. However as writing the
settings value already results in reload() to update the favorites map,
the new app is usually already in the map when we add it.
The only exception is when the ID was found in the RENAMED_DESKTOP_IDS map,
in which case we end up adding both the renamed app and the original one.
Fix this by simply relying on reload() to properly update the map, just like
we already do in _removeFavorite().
https://gitlab.gnome.org/GNOME/gnome-shell/issues/471
On X11, reactive chrome must be added to the input region in order
to work as expected. However that region works independently from
any window stacking, with the result that the unresponsive-app dialog
currently blocks all input in the "covered" area, even in windows
stacked above the unresponsive window.
The correct fix would be to track the unobscured parts of the dialog
and set the input region from that, but that's quite cumbersome. So
instead, only track chrome when the corresponding window is focused
(or the dialog itself of course).
https://gitlab.gnome.org/GNOME/gnome-shell/issues/273
As a mount operation's UI may be reused (for example after mistyping
the password), we only close the operation once the mount has finished
(successfully or with error).
We therefore need to track ongoing operations, which we currently do
by monkey-patching the corresponding volume object. However while the
underlying GVolume object indeed remains the same through-out the
operation, the JS wrapper object isn't referenced anywhere and may
thus be garbage collected, resulting in a stuck dialog.
Fix this issue by tracking active operations explicitly, so that all
involved objects are referenced until the end of the operation.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/565
Whenever a command runs in the run dialog, it
will be added to the history unless it is
already the last entry. This does not apply
for entries that are not consecutive, which can
result in long chains of commands which
alternate, e.g. lg, r, lg, r, lg, r. Not only is
this wasteful in terms of space, but also
inconsistent with how history works elsewhere,
e.g. in the shell.
Therefore, remove entries in the history that are
equal to the one that will be added to the end of
of the history when the entry already exists.

The `hints` and `settingName` parameters to the agent call may define
the specific list of secrets NM actually needs from the user. This
seems to have been the intended use of these two parameters but only
recently did NM with the IWD backend start to use this to request 802.1x
secrets. So if `hints` is provided, ask user for the specific secrets
listed there and don't even look at what type of EAP method is in use.
Only the three types of secrets actually in use by NM's IWD backend are
supported for now -- they happen to be the same three that
_get8021xSecrets() had already supported.
