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.

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.

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.

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.

The minimap is currently created once when populating the overview,

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

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.
Connect to 'workareas-changed', and update the workarea, the radius bounds,
and relayout when workareas change.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1691>
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

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
should be animated.
Implement that via a new :collapse-fraction property on ThumbnailsBox,
and use that to transition both the height of the box itself and the
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

of the visibility, and let the overview controls take it into account

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

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

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.

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.

It should enter the same transitional state it does for animations. This

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.

We now have multiple touch swipe gestures with matching fingers and

Some actors don't have the scale applied to them directly but are

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.

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

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

because that implies disconnecting from all the events and then ignoring

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.

The icon and close button might be overlapping the window actor but

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

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.

Decouple the verification failure count increase from
_verificationFailed as there are some cases in which we may want to
increase it without emitting a verification-failed signal.

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.
