What this signal does is fire when a window was grabbed. A receiver
might want to do something special when a window was grabbed, whereas
"reset" can mean anything. Rename the "reset" signal to
"window-grabbed".

Instead of interpolating our workspace and layout boxes for each child
using clutter_actor_box_interpolate(), use our Util.lerp() function and
stay in JS land instead.
This is quite a large performance improvement since it avoids
heap-allocating a new ClutterActorBox for every child. With this, we're
finally at a duration of 1.0 ms to allocate the Workspace with 20
windows.

Move the get_preferred_width/height() and allocate() vfunc
implementations of WindowPreview to C, subclassing the C GObject from
JS.
This gets us another significant performance gain, allocating a
workspace with 20 windows now only takes 1.2 ms.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1743>
It turned out that getting properties and saving them to a variable
outside of loops instead of accessing them everytime inside the loop can
have significant impact on performance, so do that in Workspaces
vfunc_allocate().
Here the impact is not that large, about 0.05 ms with 20 open windows,
that still seems worth it though.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1743>
These checks aren't needed since Clutter should enforce this for us
already and skip the implicit transition when possible. This gets our
time spent in vfunc_allocate() down to 2.0 ms with 20 windows

Setting four properties is more expensive than calling two C functions,
so move to set_origin()/set_size() calls for our ClutterActorBox
handling.
This gets us down to an average time of 2.1 ms spent in vfunc_allocate()
with 20 windows
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1743>
We can save a little bit of time in this loop by iterating directly
over the windowSlots array instead of iterating through children and
then performing a search for the windowSlot. This saves more time and we
only spend 2.2 ms instead of 2.3 ms in vfunc_allocate() now.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1743>
This layout manager is used quite often and the time we spend calling
it's allocate and get_preferred_width/heigth functions increases with
every open window.
We can save a lot of precious time during the layout cycle by moving
this layout manager from JS to C, thus avoiding the overhead of
trampolining between C and JS land.
In a measurement where the average time spent in vfunc_allocate() of the
Workspace actor was measured while opening an overview with 20 windows,
the average time spent went down from 3.1 ms to 2.3 ms.

Right now we always recreate the icon of the appMenu when calling
_sync(). This will relayout the panel everytime we open the overview,
because we call _sync() in that case.
We can easily avoid that by only recreating the icon actor in case the
app that's opened actually changes. This gets us close to doing no more
relayouts of the panel when opening the overview.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1733>
We already set the AppMenuButton to be non-reactive and transparent when
we hide it. Hiding it completely using clutter_actor_hide() will
additionally make it no longer affect layout and thus queue a relayout.
Since we hide the appMenu in the overview and we want to avoid
relayouting the panel when entering and leaving the overview, don't
completely hide the AppMenuButton to avoid queueing this relayout.

This updates the use of bind_cairo_surface_property for the changes

If the window wasn't in _windowSlots, the index is -1, so the last
element of the array is removed, leading to
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3547
I logged the stack trace from removeWindow() and it seems that when you
move the window from the second monitor to another workspace like shown
in https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3547,
removeWindow() is called twice for it, presumably once for the second
monitor workspace, and then once for the first monitor workspace for
some reason. It is during that call that _windowSlots doesn't contain
the window, so instead the last element (index -1) is removed, leading
to the animation bug.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1727>
We block state updates while the indicator for the active workspace
is animating. To track that, we check whether the scroll-adjustment's
value matches the active workspace index. That works as long as the
adjustment's value changes after the active workspace, but not when
switching workspaces via SwipeTracker which only changes the active
workspace after transitioning to the new scroll value.
To fix that, update the indicator on workspace changes as well.

Animating items of the iconGrid involves calling a few more C functions,
which is quite slow. Especially calling ClutterActor.set_easing_delay()
is slow because we override that function in JS to adjust for the
animation slow-down factor. So add a small class variable to make sure
we only animate the icons of the grid when we actually need it.
This makes the average time spent in vfunc_allocate() of the iconGrid go
down to about 0.7 ms.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
It's quite slow to access class variables in JS, especially when they're
backed by GObject properties. To avoid accessing them in every iteration
when we're looping through the children of iconGrid, store those values
to another variable and reuse that inside the loop.
This shaves off another 0.2 ms from iconGrids vfunc_allocate(), getting
the average time spent in that function down from 1.3 ms to 1.1 ms.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
Using a preexisting array to iterate over is much faster than iterating
over the actors children using a "for ... of" loop, that's because the
latter calls into C functions to get the next actor all the time.
Also, stop using array deconstruction here, it turned out that this is
extremely expensive. When profiling this part of the code, it turned out
that only 9% of the time spent in _getChildrenMaxSize() is spent calling
the get_preferred_height/width() methods. When not using array
deconstruction, this time increased to 22%, still not great, but a lot
better.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
We need to access the visible children of a page in inside
vfunc_allocate(), and since getting those children is quite slow (it
involves iterating over all the children of the actor) let's avoid that
and cache the array instead.
This reduces average time spent in vfunc_allocate() of the iconGrid from
1.6 ms down to 1.4 ms.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
We call this._getChildrenMaxSize() from the allocate() vfunc of
IconGridLayout. Since the function is quite expensive, it slows the
layout process down a lot, so instead of re-calculating it on every
relayout, cache the max size of children.
This makes the average time spent in vfunc_allocate() of the iconGrid go
down from 2.3 ms to 1.6 ms.

Instead of always aligning window previews vertically at the bottom of
their row, only do that if we have multiple rows. If there's only a
single row of windows, align every window vertically centered.
This is a very small step towards the new layout for window previews in
the overview, but since the release of 40 is getting nearer and nearer,
changing more is not feasible anymore.

To ensure the workspace thumbnails are vertically closer to the window
picker than to the search, scale down the wallpapers by a fixed number
of pixels. Using 24 px for this means we'll take of 12 px at the top and
12 px at the bottom of the wallpaper, that's a better strategy than
always scaling it by a fixed factor since it doesn't change with the
monitor size.

The back → transparent transition gives it a very bad look when
booting and running the startup animation.
Use the same transition duration hack to ensure that the panel
starts completely transparent.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1678>
There's this little hack that we do to match the panel transition from
transparent to black with leaving the overview via swipe down. The only
problem is that, while the duration of the panel transition itself is
matches, the corners don't, and they get out of sync.
This isn't very noticeable with the swipe gesture, but it'll be much
more prominent when booting straight into the overview.
Bind the 'style' property of the panel to the corners', so that the
transition duration hack applies to all of them.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1678>
The new startup animation consists of rising the Dash from the bottom,
falling the search entry from the ceiling, and going from HIDDEN to
WINDOW_PICKER with an opacity applied.
One little trick from IconGridLayout was added to ControlsManagerLayout,
which is a promises-based wait for allocation. This is required to make
sure that the transformed position of the search entry is valid, which
is only the case right after an allocation.
This animation also ensures that the overview is shown right on startup.
For session modes that do not have an overview, continue using the same
fade + scale animation.

We want to avoid updating the input region on startup, since it incurs
in roundtrips to the X server, but not workspaces struts, since they
affect the visible clip of wallpapers in the workspace. Since next
commits will make the overview be the after-boot screen, we really
don't want the wallpaper to be clipped wrongly.
Allow updating regions while starting up, but only workspace struts.
Make sure input is not updated by accounting for 'this._startingUp'
on 'wantsInputRegion'.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1678>
This is an X11-specific routine, and building the list of input region rects
on Wayland is a waste, since it incurs in many trampolines only to throw them
in the trash.
Don't build input region rects on Wayland. By modifying the 'wantsInputRegion'
variable, it also skips actors that only update input, which is another small
optimization for Wayland.

LayoutManager doesn't update struts when there's any modal running. Turns
out, the Overview itself is a modal. That, and the fact that the Overview

Let the goToPage call afterwards to take precedence, instead
of resetting the adjustment (thus the view) on the side.
This resulted in strange state when the last page contains
a single icon, and it is dragged. The last page being emptied
triggers a pages-changed signal, which half resets the view
to the first page while DnD is ongoing.
Letting goToPage do its business means we neatly clamp to the
closest page to currentPage, the last page in that case.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
When clicking on the page hints, the hint rectangles being visible
in place and not moving together with the page is a bit too
distracting.
Since the page hints are not part of the iconGrid hierarchy and
we have just 2 general ones for prev/next page (i.e. no page
associated), do this sliding via some smoke and mirrors: We don't
slide the page hints, but a parent container for both of them, and
we also control opacity so that the container is fully transparent
mid-page. At the point it is transparent, the container can be
snapped to the other side of the page, and faded back in as it
slides together with it, so it always looks like it goes away and
comes from the right sides.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
Depending on the available horizontal space, we may want to manipulate
the icon grid and scroll view spacing to result in an optimal layout
that has space left to preview prev/next pages.
The main change here is that, when adapting to the available size, the
space given to a page does not necessarily match the available space,
as we need to be able to show more than one page at a time.
With this decoupling of available and page sizes in place, we now know
how much space there is available in order to extend the padding between
pages, or the fade effect applied to the previewed pages.
Underneath, we rely a bit less on hardcoded CSS paddings, and a bit more
on the StScrollView::content-padding property.
All put together, gives us proper space management from ultra-wide
displays, to display ratios that are close to the optimal grid ratio.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
When DnDing an icon, we show both previous/next page, and optionally
a "placeholder" actor to allow creating new pages. These sides on the
scrollview are drop targets themselves, allowing to drop an app onto
the next/prev page without further navigation.
Still, preserve the checks to maybe switch to prev/next page without
finishing the DnD operation, for finer grained operations.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
Add the necessary animations to slide in the icons in the previous/next
pages, also needing to 1) drop the viewport clipping, and 2) extend scrollview
fade effects to let see the pages in the navigated direction(s).
The animation is driven via 2 adjustments, one for each side, so they
can animate independently.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
We want to show left/right side pages during navigation, also in
FolderViews. Let this scrollview use the same style than the "all
apps" one, and generalize the name a bit.
This will compress the scrollview horizontally, so there's actual
overflow space to show these pages.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
Instead of taking just vertical/horizontal offsets, take a ClutterMargin
to allow us set the fade offsets on each direction specifically. Also,
handle negative values in margins, the fade effect will run in the negative
space left by the scrollview padding instead. Another difference now is
that areas outside the extents of the effect will be transparent, instead
of the effect ending abruptly past the given extents.
This will be used by the app grid, in order to selectively let see either
of next/prev pages while navigating.
While at it, fix code style issues in st_scroll_view_update_fade_effect(),
and clean up unused variables from the GLSL code.

The workspace minimap is much less prominent than the old workspace
switcher, and serves primarily as an indicator.
That means that duplicating it on secondary monitors (if workspaces
on non-primaries are enabled) is harder to mistake for per-monitor
workspaces, so make some people happy by including the minimap on
every monitor.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
Now that the backgrounds was moved into workspaces, the fullscreen
views on secondary monitors are visually inconsistent with the
primary view, as there's no dash or search entry that reduces the
available height and allows adjacent workspaces to peek in.
Address this by adding padding above and below the view, so that
it is limited to 70% of the available height.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
Right now the handling of external monitors is relatively simple, and
consists of putting either an extra workspace or a full view on the
monitor, depending on the workspaces-only-on-primary setting.
We are about to tweak the behavior on secondary monitors, prepare for
that by splitting out an intermediate actor that manages the views on
non-primaries.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
At the moment views on non-primary monitors take up the entire work area,
so simply allocating the available size works. However we'll soon shrink
the views a bit to match the visuals on the primary monitor. As workspaces
keep the ratio, reducing their height will also reduce the width; override
the default allocate() to keep the extra workspace horizontally centered.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
At the moment, we only get the initial :should-show value when populating
the thumbnails. That only happens when entering the overview, so any
listeners to notify::should-show will perceive it as a change rather
than an initialization, which can result in unwanted transitions.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
We currently initialize the porthole to the screen size instead of
the monitor's work area we actually want. At the moment this doesn't
matter, as the minimap is created during initialization with the rest
of the overview, so we can expect a work area change that updates the
porthole to the correct values.
That won't be true for minimaps we put on secondary monitors, so make
sure we initialize the porthole to the actual values.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
The minimap is currently created once when populating the overview,
and kept around until the end of the session. That will change when
we start to also show it on secondary monitors, so do proper clean
up when destroyed.

This is used to detect whether a click was short enough to select a
window and activate it or long enough to start a drag. Usually when
clicking on a window and selecting it, this leaves the overview, but
when clicking on a window on a neighboring workspace, the overview is
kept open, but selected is not unset in this case. So all attempts at
dragging the window after using it to switch workspaces will fail.

The property describes the target visibility (that is, the visibility
that will be set after the ongoing transition), and is therefore updated
at the start of the transition rather than from hideDone().
The overview gesture currently misses resetting it at the end, so it
is only updated to the correct state the next time the overview is
entered.

When adapting the check to the new versioning check, we just blindly
copied the old behavior for stable/unstable versions:
- stable releases must have matching major numbers
- unstable releases must match major and minor ("alpha", "beta", "rc")
That worked for the old even/odd scheme, but now has the absurd effect
that we consider an extension that lists "40.alpha" in its shell-version
incompatible with "40.beta", but compatible with "40.2".
At least this provides us with a good opportunity to reconsider the
behavior. While it is true that breakage is much more likely between
unstable releases, in practice extensions are either following shell
development closely or update once around the time of a stable release.
For the former, the stricter check isn't usually too useful (as the
extension releases around the same time as gnome-shell anyway).
For the latter, it's annoying that ".rc" is treated differently from
".0" and requires an update to become compatible.
The latter is also by far the more common case, so update the check
to only match on the major version regardless of whether a release
is stable or unstable.

Since commit 9980c80619, the porthole position is ignored. As a result,
previews are only shown if the primary monitor is located at (0, 0).
To fix this, we either need to propagate the porthole to every thumbnail,
use a custom layout manager that applies an offset to all children, or
add an intermediate actor that offsets the contents.
The last option is the simplest and doesn't require calls into JS on
every allocation, so pick that one.

The preview was getting scaled up by a factor based on what is needed to
increase the width by activeExtraSize pixels. With windows that are
wider than than they are tall, this means that the size of the window
will not increase any more than activeExtraSize in any direction, but
for windows that are taller than they are wide, the vertical scaling
can exceed this. This would break some of the assumptions in the
reported size for the preview chrome and could for very narrow windows
result in a rather large scale.
To fix this, calculate the scaling factor based on whatever is larger,
the height or the width.

In the allocate() vfunc of WorkspaceLayout we use a small trick to make
the nonlinear animation paths when opening the overview less jarring:
Because a window might get smaller than its target size during the
animation, we make sure the size never drops below the final size
calculated by the layout strategy.
In the app grid the Workspace is very small though, and the size of a
window slot calculated by the layout strategy might actually be larger
than the workspaceBox. This means we might use the window slot size
instead of the workspaceBox size and end up with a window that's at the
correct position, but its size is too large.
Fix this by only applying this trick when we're animating towards or
from the state where we actually expect the workspaceBox to be larger
than the window slot, that is during the the transition from the session
to the window picker (or the other way round).

Window previews can spill out of the container when their position in the
session overflows the monitor boundaries. In the past, Workspace didn't have
a visible background, and was (almost) always fullscreen, which would mask
this particular problem. However, nowadays, it is very much noticeable when
this situation happens.
Clip the window previews container to its allocation when the overview state
is bigger than WINDOW_PICKER. That is, between HIDDEN and WINDOW_PICKER states,
inclusive, no clipping is applied.

Instead of adding it to the window previews container, add it to Workspace
itself. This requires expanding WorkspaceBackground, so add the relevant

Since the background is beneath the window previews, create and add it before

Currently, Workspace is a single actor that contains both the background,
and all window previews, and is managed by WorkspaceLayout. In the future,
this concentrating aspect of it will bite us; we want the window previews
to be clipped to the allocation, but not the background, since it will
have shadows.
Make Workspace subclass St.Widget with a ClutterBinLayout as layout manager,
and move window previews to a child actor. To reduce the impact of this
extra actor, it's a ClutterActor instead of a StWidget, and the spacing is
still set on Workspace itself.

The WorkspaceBackground class has specific code to clip the background
to the workarea. However, it doesn't monitor for workarea changes, which
means it cannot react after being created.

and relayout when workareas change.

The primary workspace is displayed in the overview, and clipping it
ends up clipping the shadows too. Since Overview's ControlsManager
itself clips to allocation, no windows in the primary monitor spill
to other monitors. However, not clipping non-primary monitors might
end up in situations where their windows spill into the primary one.
Make sure to only clip workspace views of non-primary monitors.

The dialog is shown at session start, which right now means in the
regular session, however the plan is to start the session in the

Right now the rowSpacing and columSpacing of the layout strategy is
calculated by looking at the overlapping sizes of the close button and
the app icon of the WindowPreview, plus a constant spacing read from CSS
by the WorkspaceLayout that's added to that. We're not factoring in the
extra size of the scaled-up WindowPreviews here and instead depend on
the constant spacing being large enough. If we don't want to depend on
the spacing here, we should add the scaled-up extra size to the sizes
returned by chromeWidths() and chromeHeights().
Since the last commits all previews scale up by the same amount of
pixels, so we can now just add that size to the values returned by
chromeWidths() and chromeHeights().
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1692>
Scaling differently sized WindowPreviews by a constant factor will
result in smaller windows getting enlarged by a smaller amount of pixels
than larger windows (1000*1.02=1020 but 100*1.02=102, one will grow by
20 pixels and the other one by 2), this can look a bit weird because
smaller windows don't scale up as much as larger windows.
So introduce a constant extra size to use when scaling windows up, we
set only the half size there because we want to ensure that the size
added on both sides is not fractional and we remain aligned to the pixel
grid.

Right now the spacing between icon and title works using a little trick
that doesn't really seem intended: The title is offset by
(icon-height * ICON_OVERLAP), when the icon is actually overlapping the
preview by ICON_OVERLAP, and *overflowing* the preview by
(1 - ICON_OVERLAP).
So correct that and offset the title by
(icon-height * (1 - ICON_OVERLAP)), and since now there's no spacing
anymore, add a proper ICON_TITLE_SPACING to that offset.
Also add the new ICON_TITLE_SPACING to the overlapHeight, where the
spacing was ignored so far.

The scale property tracks the relative size at which we display thumbnails
given the space we have available.
That assumes that the allocation represents that available space, but it will
actually be smaller while the minimap itself is collapsing.
Luckily we have an easy option to avoid a distorted scale: Just don't update
it while collapsing. We expect scale changes when adding or removing thumbnails,
but as we freeze those during transitions, we can do the same with the scale.

Right now the minimap only hides itself in case of a single static
workspace. That's not only an edge case, but also not expected to
change while the overview is visible, so changing the visibility
without a transition is fine.
However that is about to change, and we'll hide the minimap as well
when there are fewer than three workspaces. As that condition is
very much expected to change from within the overview, the transition

Implement that via a new :collapse-fraction property on ThumbnailsBox,

scale of the individual thumbnails.

We currently have two components that show or hide the minimap:
- the thumbnails hide themselves in case of a single static workspace
- overview controls show the minimap when no search is active
That obviously doesn't work correctly.
To fix this, change thumbnails to set a new :should-show property instead
of the visibility, and let the overview controls take it into account
when changing the visibility.

As planned and shown in the mockups for GNOME 40, round the corners of
the background wallpaper of workspaces.
To do that we use the new rounded-clipping support of
MetaBackgroundContent and we animate the radius by attaching it to the
stateAdjustment just like everything else.
Because we show only a part of the wallpaper and "cut away" the area of
the panel in WorkspaceBackgrounds vfunc_allocate(), we also need to set
the rounded clips bounding rect to the rectangle we're actually showing,
otherwise the texture would be rounded in the region that's cut away.

This is the same as the vertical swipe gesture, but for keyboard
junkies: Analoguous to the <super><alt>left/right shortcuts for
switching between workspaces, add <super><alt>up/down to shift

The animation handling is kinda split between layout (for the
keyboard slide), and keyboard (for the focus window slide). It
would be nice to have more fine grained control on those, so
move the animation handling altogether to keyboard.js as a start.
This is roughly similar, except that transformations apply to
the Keyboard actor, instead of the keyboardBox (its parent). We
now queue a relayout after the animation in order to update the
chrome tracking.
The only layering break now is that we emit
layoutManager::keyboard-visible-changed in keyboard.js, its
purpose will be dropped in future commits, so leave it there for
now.

Gestures leaving the overview from a short distance result in an
ugly effect with the panel opacity transitionhaving a fixed duration.
Make this transition have the same duration (although in a hackish
way) so we avoid the ugly effect.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1643>
The gesture internally manipulates the main adjustment so one swipe
up brings up the overview, and a second swipe up brings the app
grid. The gesture also works in the other direction to get out of
the overview.
Internally, this is delegated on the OverviewControls, so the
adjustment is not leaked out of there. This however meant open
coding the gesture interaction so it can be directed from
overview.js code.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1643>
This will be set whenever an event controller is manipulating the adjustment.
It should enter the same transitional state it does for animations. This
will be used by the overview gesture.

Separate this logic from _switchWorkspaceBegin() and ensure it is set
before this call. The SwipeTracker code uses the orientation to determine
whether the gesture should begin at all, so changing the orientation on
gesture begin was a bit too late.
But also, that meant the SwipeTracker was left at the default orientation,
which was vertical (unlike workspaces, and like the overview gesture).
This made both swipe trackers try to handle the same swipe, with the
WorkspacesView being doubly unfortunate (for triggering in the first place,
and for happening after the other gesture did queue relayouts on it).
Taking this logic outside of _switchWorkspaceBegin() and having the right
orientation beforehand results in both gestures looking for their direction,
and not meddle with each other.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1643>
We now have multiple touch swipe gestures with matching fingers and
different directions set on the overview hierarchy. Accepting all
touch swipes without checking the direction makes one of these gestures
take control of input, without other gestures having a say on this.
So, look for the direction of the touch events and look if it matches
the expected orientation before accepting the gesture.

Make the touchpad gesture keep track of its state, and enter in a
rejected state if the swipe is happening in the wrong direction.
Effectively, this means touchpad gestures are locked on a single

Some actors don't have the scale applied to them directly but are
children of a scaled parent. In those case just retaining the scale will
not be enough and the scale of the actor itself needs to be adjusted

Even if activePage has been removed as part of commit 27627bd40, we've

When opening a large number of windows, the computed space and scale for
a layout can become negative due to the per-row/per-column spacing. This
is smaller than the initial values of lastSpace and lastSpace, leading
to a null return which then causes all sorts of other issues resulting
in the workspace becoming invisible.
This change ensures that the function always returns a layout, even if
it may look a bit broken and does not conform to the scale/space
requirements which are impossible to fulfill for the given number of
windows. It's better than displaying nothing, since it allows users to
move/close windows and restore this to a more usable state.

When we got an error, all the other HINT or INFO messages are not useful
anymore and delaying to show them is just a waste of time and may be
even wrong in scenarios with fast authentication devices.
An example are the fingerprint devices, where the user may touch the
sensor repeatedly while we may still show the "touch the sensor" hint
instead of notifying of possible errors.
So, in case we got an error override all the other errors coming from
the same service with lower priority.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1683>
Once the verification has been stopped or has failed all the messages
that are not of error type are just not needed or wrong to show.
For example, in the fingerprint case we may still show the hint to swipe
or touch the device, while the fingerprint PAM service has already been
stopped.
So filter them by adding a new function that adds a null message to the
queue, overriding all the messages that have a lower priority.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1683>
There are cases in which a service may want to override a message with
one coming with higher priority, for example an info or hint message
isn't useful anymore if we've already got an error message.
In the same way when a service has been stopped we don't care anymore
showing its info or hint messages, while it still may be relevant to show
errors.
An example is the fingerprint service that may emit errors quickly while
the hints messages should not be kept around when an error is already
queued or when the service has been stopped.
So, add function that allows to override queued messages based by their
type that follows this policy:
- Messages coming from different services are always preserved in
their original order.
- Messages (from the same service) with a priority equal or higher than
the last queued one are preserved.
- Messages matching completely the last queued are dropped in favor of
this one.

It can be convenient to get the currently showing message in order to
replace or remove it in case it's not needed anymore.
So simplify the message queue handling by only depending on a single
local variable (_messageQueue) and redefining hasPendingMessages
depending on its content.
Now messages are kept in queue till they are not fully processed and the
first message is always the one currently shown.

When a fingerprint failure event happens we may also soon receive a
conversation-stopped event with an error message (such as in the case
we hit the MAXRETRIES value), but this is going to be ignored in case we
are too quick in consider the first failure a verification-failed event
because that implies disconnecting from all the events and then ignoring
such signals.
To prevent this, add a small timeout before failing the verification so
that if we get a further event we will process it.

In the case a service is not available (as it can be in the fingereprint
case when a supported reader is available but has not enrolled prints)
we were trying indefinitely to restart it, however this can lead to
troubles since commit 7a2e629b as when the service conversation was
stopped we had no way to figure out this case and we'd end up to
eventually fail the whole authentication.
However, in such cases the PAM services are expected to return a
PAM_AUTHINFO_UNAVAIL and gdm to handle it, emitting service-unavailable
signal.
So connect to ::service-unavailable and keep track of the unavailable
services so that we can avoid retrying with them.
In case such service is not the foreground one, we can just silently
ignore the error as we did before commit 7a2e629b, without bothering
failing the whole verification.
In case we got a valid error message on service-unavailable, we also
show it, this is normally not happening unless GDM isn't redirecting
here other kind of problems (such as MAXTRIES) which are supposed to
stop the authentication stopping any further retry.

When creating an icon for the system actions search provider, set the

The icon and close button might be overlapping the window actor but
were not considered in has_overlaps() which gets used to decide whether
to offscreen the actor for transparency. Since currently the icon is
visible when the preview is dragged and the whole actor is turned
transparent, the opacity will not be applied to everything as a whole
but the child actors individually. This leads to the window becoming
visible behind the icon.

Calling startTouchGesture() on the workspacesViews can change the
visibility of the workspaces if not all of them are already shown, such
as when there are more than 3 workspaces or for 3 workspaces if we are
not on the central one. This invalidates the allocation and the width
used as distance for the gesture would become 0, resulting in drag
gestures immediately jumping to the first or last workspace due to a
division by 0.

Currently when the foreground service conversation stops we increase the
verification failed count and try to start it again, while if a
background service has been stopped we just ignore it.
This is causing a various number of issues, for example in the case of
the fingerprint authentication service, it is normally configured to die
after a timeout, and we end up never restarting it (while the UI still
keeps showing to the user the message about swipe/touch the device).
So, in such case let's just consider it a "soft" verification failure
that doesn't increase the failures count but will cause us to reset the
UI and try to restart the authentication (and so the affected service).
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1652>
Wiggle may make the error message to be visible for less time so provide
the auth prompt an API to increase the timeout to be used for showing a
message in some cases.
This could be reworked when we'll have a proper asyn wiggle function so
that we could just make the user verifier to "freeze", then await for
the wiggle transition to complete and eventually release the verifier.

Currently whenever an authentication failure happens we wiggle the
entry, however this may not be related to the service which failed.
For example if the fingerprint authentication failed for whatever reason,
there's no point to wiggle the text input as it's something unrelated to it.

coming from the querying service.

Fingerprint PAM module can have multiple failures during a runtime
and we rely on the pam module configuration for the maximum allowed
retries.
However, while that setting should be always followed, we should never
ignore the login-screen's allowed-failures setting that can provide
a lower value.
So, once we have a fingerprint failure let's count it to increase our
internal fail counter, and when we've reached the limit we can emit a
verification-failed signal to our clients.
As per this we need also to ignore any further 'info' messages that we
could receive from the fingerprint service, as it may be configured to
handle more retries than us and they might arrive before we have
cancelled the verification session.

When the login/lock screen is shown the error messages for background
services are always ignored.
However, in case the service is the fingerprint authentication method
we still want to be able to show error messages to inform the user
about what failed, and eventually that the max retries (that may be
different from the login screen configuration) has been reached.
This handles partially the design issue [1] related to the login/lock
screen fingerprint authentication.
Eventually we want to use pam extensions to use clearer and parse-able
messages, however in the case of the fingerprint service we can be sure
that the fprint PAM module will only send errors on auth failures.

Checking whether the item is empty is now the history’s job, per the
previous two commits. The history also trims the input for us.
The effect of this is that we call _history.addItem(), and thereby move
to the end of the history, even if the input is empty (or consists only
of whitespace); clearing the input field and pressing Enter becomes a
quick way to jump back to the end of the history. (The current history
item is not overwritten if the input is empty.)

This ports the runDialog changes of [1] to the underlying history
component, where they can benefit looking glass as well: the history is

stored if empty. (Note that _setPrevItem and _setNextItem already
skipped updating the history if the entry was empty.)
Since both users, runDialog and lookingGlass, also need the trimmed
input for other reasons – runDialog to avoid issues when interpreting
the command as a file path (if it can’t be executed as a command),
lookingGlass to decide whether a command should be run at all – have
addItem return the trimmed input. (runDialog and lookingGlass are not
yet changed to take advantage of this – that will be done in separate
commits.)

When verification failed using a specific authentication service we're
currently restarting the whole user authentication system, which leads
to lots of unneeded operations (reinitializing a new user verifier proxy,
restarting all the gdm workers with the relative PAM modules and so on).
And this makes also debugging of login problems more complicated, given
we're cluttering the journal with repeated data.
However, at reauthentication failure GDM has already set up for us an
user verifier that we can use reuse to start only the service that had a
failure. So when possible, just start a new service instead of rebooting
the whole authorization process.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
When retrying the authentication we should make sure that all the
previously initiated services are stopped in order to begin a new
authentication session with all the configured services.
Unfortunately at the current state we only dispose the currently used
user verifier, but we don't make it to stop all the relative gdm workers
and then they'll stay around potentially blocking any further usage of
them (as it happens with the fingerprint one, that has unique access to
the device).
So, cancel the currently running authentication before starting a new
one if we're explicitly retrying.

When a verification session has failed we may want to wait for the user
to have completed all the waiting queries and to have read all the
incoming messages, however during such time an user verifier should
not be allowed to queue further messages to the UI, as we're about to
completely stop the identification or start a new one.
Unfortunately this is not true because we're still connected to the
identifier signals, and so we may still show messages.
This is particularly true when using the fingerprint PAM module as it
may restart the authentication while we're in the process of stopping
it.
So, keep track of all the signals we've connected to, and disconnect on
verification failed and during cancel/clear operations.

As per previous commit the user can cancel an ongoing authentication via
Escape key and that will always send the user back to the clock view in
lockscreen or user-selection view in login prompt.
However, we can be a little more permissive and don't switch view to be
able to restart the authentication without further action.
To avoid this to be abused though, we consider the user verification
cancellation via escape key to be a "soft-failure", so once the
configured "allowed-failures" gsettings value has been reached, we'd
just act as before, ignoring any further request (until we don't get
back to the user auth view).
In this way we still make brute-force attacks harder to do, while still
giving the well-behaving user some ability to fix mistakes.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
Escape key is supposed to cancel a verification, however if the user
already hit Enter to begin the authentication the Escape key won't work
until the verification completed.
This may be quite inconvenient when an user did a typo while writing and
wants to cancel the already started auth.
So, while authenticating (or in general while the entry is unsensitive)
give the key focus to the authpromt itself so that we can still get the
input events and cancel an user action.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
When a cancel event in the user lockscreen happens we first emit a reset
signal and immediately a cancelled one.
This lead to start a new gdm worker for each enabled authentication
method and then immediately to stop it.
As per the previous commit, we don't have anymore dangling gdm workers
around, but still we should not even start a new one in such case.
So, when the user explicitly cancelled the authentication session, first
emit a cancelled event and only emit a reset event with a begin request
if we are outside the lockscreen.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
When we cancel an user authentication via Escape key or cancel button on
AuthPrompt we reset the view and we emit a 'cancelled' signal that leads
to destroying the auth prompt and the user verifier.
However, the verifier may still have an operation in progress and its
completion may take some time (as in the case of gdm-fingerprint), but
we just leave the gdm worker running until its pam module completes
(potentially never) clearing and disposing its handle.
So, instead of just clearing the verify, actually cancel and clear it.
In case the user verifier is set, clearing the relevant data will happen
anyway as part of the cancel() call.
Ideally this would have been handled by gdm itself, but unfortunately we
can't fix it there because the verifier itself is a class generated by
gdbus-codegen, so we can't handle this automatically on disposal nor we
can automatically monitor when the caller proxy is stopped on our side.

The behavior of workspaces is different depending on whether
the overview is in window picker state, or app grid state.
When in window picker state, clicking on adjacent workspaces

app grid state, clicking on a workspace must always hide the
overview.

The overview transition consists of getting the initial and final
states of the overview adjustment, derivating various other internal
states from them (such as the fit mode, opacities, translations, etc),
and finally interpolating the allocation boxes.
When interpolating between the fit mode, WorkspacesView uses the current
allocation box to derivate the SINGLE and ALL fit mode boxes. However,
that creates a curved path during overview transitions. What we really
want to do here is calculate the fit mode box relative to the corresponding
overview state. For example:
+----------------+----------+------------------------+
| Overview State | Fit Mode | Workspaces geometry |
+----------------+----------+------------------------+
| HIDDEN | SINGLE | Cover entire screen |
| WINDOW PICKER | SINGLE | Between minimap & Dash |
| APP GRID | ALL | 15% screen height |
+----------------+----------+------------------------+
Using the table above as the reference, when the overview transitions
between WINDOW PICKER and APP GRID, we must interpolate between
(SINGLE fit mode @ between minimap & Dash) and (ALL fit mode @ 15% screen
height). That way, we always interpolate the final boxes, which corrects
the odd path that workspaces follow during this transition.
Make the WorkspacesView of the primary monitor use these cached boxes
when the overview is in the middle of a transition, and the fit modes of
the initial and final state differ, to calculate the workspaces positions.

Move AppDisplay, WorkspacesDisplay, and ThumbnailsBox from ViewSelector to
ControlsManager. This allows to always allocate the correct size for AppDisplay,
and will enable for a plethora of further improvements. The end goal is to
completely remove ViewSelector, and let ControlsManager handle the layout of
everything that's visible in the overview.
For now, replace the apps page with a dummy actor in ViewSelector.
Adjust various callers around the codebase to not access the ViewSelector
directly from the overview anymore.
Bind the opacity of the primary workspace to WorkspaceDisplay's opacity. This

Now that Overview is able to ease into any state, be it window

WorkspacesView uses the floating layout when the overview is in window
picker mode, and the session layout when the overview is in app grid
mode. Up until now, the fit mode adjustment was used to derive the
workspace mode, but it is incomplete as it doesn't have the full range
of workspace states.
Make ViewSelector cascade the overview adjustment to WorkspacesDisplay,
and use the overview adjustment itself to derive the workspace mode.
Extra workspaces don't have to account for the fit mode, and thus are
basically a clamp(state, 0, 1) of the overview state. However, don't
call animateTo/FromOverview() anymore, since they ease the workspace
mode adjustment.

Boy, does this commit feel good.
While the workspaces view on the primary monitor *appears* as part of
the overall overview hierarchy, this hasn't actually been the case
until now. We synchronized its size and (stage) position to match
the workspaces display, but actually kept in a separate layer for
the transitions to and from the overview.
But now that the new layout manager slides out completely during the
overview transitions, the workspaces display starts out covering the
entire work area, which is exactly what we need for the transition.
So finally stop faking it, and actually make the primary workspaces
view a child of the workspaces display.

Instead of delegating it to ViewSelector, make the transition to and from
overview ease the main state adjustment.
This commit temporarily breaks these animations, but on the other hand
introduces an important feature: ViewSelector is always allocated to the
actual size. This will finally allow for adding WorkspacesView as a child
of WorkspacesDisplay, and finally remove the actual geometry hack, which
is what next commit is about.

Currently, ActivitiesContainer reacts to showAppsButton and
transitions between app grid and window picking states on
its own. In the future, we want full control over this.
ControlsManager already has a state adjustment that represents
all possible overview states. Propagate this adjustment up to
ActivitiesContainer, and use it to drive the transition.
This requires moving the callback to the showAppsButton to
ControlsManager, since now it control the state adjustment
itself, not ActivitiesContainer's adjustment.

Currently, gnome-shell uses the wrong scrolling direction for
horizontal scrolling events.
When dx < 0 for a smooth scroll event, then the scrolling direction is
supposed to be Clutter.ScrollDirection.LEFT, instead of
Clutter.ScrollDirection.RIGHT, as dx is smaller than 0.
Fix this issue by swapping the values LEFT and RIGHT.

It is possible for an initiated session to complete without
a request if polkit can authenticate the action without user
input. We fail to clean up after ourselves in that case, as
the cleanup is done after the dialog is closed.
The dialog can still be shown when the code that hides existing
dialogs while the screen is locked shows it on unlock. But as
the session was closed, the dialog is now defunct and cannot
be dismissed by the user.
Fix this by running the cleanup on close() when the dialog
wasn't shown.

Previously we used a bunch of heuristics for this. We checked if velocity
was directed towards the nearest snap point and its value was larger than
a threshold. If it is, we completed the swipe, otherwise we cancelled it.
This was good enough at the time, because this code was originally written
for back/forward swipe. Since then, the swipe tracker was extended to
handle arbitrary snap points and not just 0 and 1, or -1 and 0, depending
on text direction. After that it was iterated on, but never significantly
redone.
This worked well enough, but had two problems:
1. In some cases, notably overview, it may be wanted to be able to swipe
through multiple pages at once. This wasn't really possible because we
always picked the adjacent snap point.
2. Since we can't do that well, we want to restrict swipes to one page at a
time. It was done in a rather hacky way by clamping the position into
[-1, 1] range from the place where we started the swipe. This works
if we start the swipe from idle position, but if an animation was
already going, the range would be clamped to arbitrary values, and very
likely containing only one snap point, which we already swiped past at
this point. In this case, finishing the swipe would cancel it regardless
of velocity. This means that if one tries to quickly move through
carousel pages via swiping, half of the swipes will be inexplicably
cancelled.
We'll use the deceleration formula from
https://medium.com/@esskeetit/how-uiscrollview-works-e418adc47060#10ce
to calculate then projection point, then pick the nearest snap point and
calculate the duration as we did before. It works well enough for short
distances, but has two problems:
1. It caps the maximum distance at a pretty low value - about 5 pages in my
testing.
2. With how we pick the nearest snap point, it's too easy to accidentally
cancel the swipe,
To combat the first problem, we can modify the curve: only use linear
function at small distances, and smoothly transition it to a parabola
further.
For the second problem we can add two special cases: first, if the swipe
ended up between the initial snap point and the next one, we always prefer
the latter. Second, a good old velocity threshold for cancelling.
We'll also use a slightly smaller deceleration value for touchpad: 0.997
instead of 0.998.
Now that we can pick any snap point, the [-1, 1] clamping doesn't make
sense anymore, so instead let's replace it with a more flexible
mechanism: if we're near a snap point, pick its adjacent snap points.
Otherwise, take the two nearest snap points, and take their adjacent
snap points. This way we have 3 snap points to choose from when
starting a swipe from an idle position, and 4 if we start during an
ongoing transition.
This way, if we've just swiped from snap point n to n+1, the transition
will pick snap points n-1, n, n+1, n+2 and if we swipe again, we will
likely land on n+2. During that transition, if we swipe again, it will
likely have already passed the snap point n+1, so this time the available
snap points will be n, n+1, n+2, n+3, so we can swipe again and it will
still complete, and so on.
This will make it easy to allow multi-page swipes as well, by just
removing the clamping.

In some cases we may get anevent with very low delta at the end of the
swipe. While we can't completely ignore them, we can smooth them using a
scroll history, similarly to what GTK kinetic scrolling does: keep track
of the last 150ms of events, and sum their deltas when calculating the
velocity.
The logic is based on what GTK does in GtkGestureSwipe and
GtkEventControllerScroll.

Let empty input result in an error, just like other invalid commands
(bad syntax, nonempty whitespace, etc.). GLib already has an error
message “Text was empty (or contained only whitespace)” which it shows
for whitespace-only input, so letting that message apply also to empty
input makes sense.
This requires some tweaks further down the file to avoid interpreting
empty input as an empty path (relative to the home directory) and then
opening the home directory.

The Message class this is derived from unconditionally adds a close
button with 0 opacity that only gets shown on hover for messages that
can actually be closed. The MPRIS MediaMessage however can never be
closed and having a close button can cause the title to be cut short
unexpectedly.
Similarly the secondary text which other notifications use to display
the notification time is always left empty here as well.

So far, we couldn't allow workspace scrolling outside the overview

The code to update the actor position based on the cursor and current
scale was run in a 'new-frame' handler. This is working fine when
animations are enabled, but when they are turned off this does not work.
This is because the 'new-frame' signal is emitted before the changes for
that frame are applied. So with animations off the position was only
ever updated with the starting values. As a result the shrunk actor was
not being dragged by the position where it was clicked, but by where it
was clicked in the original size, which is likely not even on the shrunk
actor.
This change now also updates the position in the onComplete handler
which gets run with the final scale, even if the duration is 0.

When vertically snapping, WorkspacesView currently allocates workspaces
side-by-side, then applies an extra step of translation to center to
the active workspace. This extra step, however, gets in our way because
now we need tighter control of the workspaces positions in allocation,
in order to properly interpolate them.
Move the translation of workspaces to the allocation code itself, and

Currently, WorkspacesView positions each workspace on a
per-page layout, each page with the allocated width and
height of WorkspaceView. This layout doesn't work well
with horizontal workspaces.
Layout workspaces side by side, instead of per page. The
layout is influenced by a "fit mode", which reflects the
different behaviors exposed in the mockup. This fit mode
represents whether a single or all workspaces will fit
available geometry.
The single fit mode is always used for now. Next commits
will make it switch to the all fit mode when in the app
grid state.
The translation_{x,y} also needed to reflect the switch to
a side-by-side layout, and use the geometry of the workspaces
to determine the offset. Notice that, when the fit mode is ALL,
there's no translation applied.

The new window preview overlay requires getting the app icon for a
window from the window tracker when it gets initialized. The window
tracker listens for the same 'window-added' signal on the MetaWorkspace
that the gnome-shell Workspace listens for to add the window preview.
The window tracker however reconnects all its signal handlers whenever
the number of workspaces changes, which means that its signal handlers
get called after the ones in Workspace ones. So by the time the
'window-added' handler in Workspace is called, the window tracker does
not have an app associated with the window.
To fix this ensure that all window related signal handlers in Workspace
are run after the ones in the window tracker.

Currently, there's one animation for the whole canvas. While it looks fine
with just one screen, it causes windows to move between screens when
switching workspaces. Instead, have a separate animation on each screen,
and sync their progress so that at any given time the progress "fraction"
is the same between all screens. Clip all animations to their screens so
that the windows don't leak to other screens.
If a window is placed between every screen, can end up in multiple

Currently, the workspace swipe transition only has one workspace in each
direction. This works until you try to do multiple swipes in quick
succession. The second swipe would continue the existing transition, which
only has 2 or 3 workspaces in it, and will hit a wall.
To prevent this, take all workspaces and arrange them into a column or row,
depending on the layout, and use that as a transition.
For the transition that happens when focusing a window on another workspace
(for example, via Alt+Tab), still use only two workspaces instead of all of
them.
Since we don't support layouts other than single rows/columns anymore,
diagonal transitions aren't supported anymore, and will be shown as
horizontal or vertical instead.
Since nw alt-tab and gesture transitions are different, don't allow to do
both at once, that is, disable swipe tracker when a programmatic transition
is going. This will also conveniently cancel a gesture transition if a
programmatic one is initiated while a gesture is in progress.
