25793b9d97 status/network: Disable modem connection when windows aren't allowed
The item launches the corresponding Settings panel when activated, which
doesn't work when windows are disabled by the session mode. Rather than
failing silently, turn the item insensitive.

b156cabdc9 swipeTracker: Use unaccelerated deltas
Unaccelerated deltas make sure the gesture works the same regardless of how
fast the fingers move; this is what we were already doing for scrolling.

Remove the swipe multiplier as the deltas already match scrolling other than
the 1/10 multiplier Clutter applies to scrolling specifically.

20d99c69cb search: Exclude hidden results from keynav
Since commit 3fb02843, we no longer skip allocation for
results that don't fit the width, and give them a 0x0
allocation instead.

That has the unintended side effect of those children now
being available to keynav. There are cases where we want
0-sized actors to be part of the focus chain (e.g. FocusTrap),
but this isn't one of them, so explicitly exclude 0-sized
children from keynav.

6995c2fa9f shellInfo: Don't destroy source on undo
Destroying the source from an action callback will result in the
notification being destroyed twice:

 - source.destroy() destroys all its notifications

 - a notification destroys itself after an action
   was activated

This results in unwanted log spam when attempting to dispose the
notification for a second time.

There is actually no good reason for destroying the source explicitly,
as sources already self-destruct with their last notification.

1f4eea12a5 messageTray: Always remove destroyed banners
Currently we only mark the banner as removed if it is destroyed
while in SHOWN or SHOWING state, but not if we're already HIDING
(for example in response to `NotificationBanner::done-displaying`).

If this happens, we'll try to destroy the notification again at
the end of the transition, which leads to (harmless but annoying)
log spam since Notifications were turned into GObjects (that are
disposed when destroyed).

Address this by always marking destroyed banners as removed, while
still only triggering a state update while shown (or in the process
of being shown).

8be5d33611 windowManager: Remove timeout on starting X11 services
With Xwayland started on demand, mutter/gnome-shell will spawn Xwayland
and GNOME settings daemon Xsettings.

Currently, gnome-shell uses a timeout of 5 seconds before canceling the
launch and declare failure to start X11 services.

While 5 seconds may seem like a lot of time, when this is executed on a
virtual machine part of a QA tests under load, this causes random
failures.

There is no good value here, we could increase the timeout but it will
always remain racy. Instead, remove the timeout, systemd itself already
has a timeout mechanism (with a much longer wait time).

5be67eb190 lookingGlass: Only pop modal after the transition
Right now we pop the modal immediately when closing, so the key-release
event of the Escape key ends up in the focus window which may consume it
for leaving fullscreen mode or similar.

We can avoid that in many cases by keeping the modal grab until the end
of the transition, as the key-release event will then likely occur while
the grab is still in place (provided animations are enabled).

6fc93b78bc appDisplay: Improve app grid interaction for touch devices
Currently, handling of touch devices in the app grid is a bit awkward,
paging by dragging the view can only happen if started from the gaps
between icons, trying to drag from an icon will trigger DnD, and popping
up the menu takes over it all.

Instead, have the app grid actions play this game of rock-paper-scissors:
- Fast swipes on icons trigger scrolling, beats DnD and menu
- Slower press-and-drag on icons trigger DnD, beats scrolling and menu
- Long press triggers menu, beats scrolling, is beaten by DnD

This allows quick swipes to handle navigation, while still allowing the
fine grained operations. DnD, when triggered, dismisses the menu, if
shown.

This all could probably be nicer with a more stateful gesture framework,
we're not there yet though.

019229c40e windowManager: Return failure to start X11 services
If for some reason the xserver failed to start, mutter/gnome-shell
should not attempt to connect to the X11 display otherwise it will
lock up in XCB.

An indication of such a premature failure of the xserver is when the X11
services fail to start.

Return the status so that the caller can cancel the connection in time
and avoid the lockup of mutter/gnome-shell in case of failure.

This, however, makes the X11 services a critical component to start
Xwayland, meaning that a failure to start those services for any other
reason than the xserver failing to start would still prevent Xwayland
and therefore X11 clients to run in Wayland. This is however a lesser
issue than mutter/gnome-shell locking up.

Previously the workarea was only set on construction and then never

allocation were based on an outdated workarea size when it changed after
construction. This for example was happening during the startup

is shown. This caused the workspace in the overview to be slightly
smaller when it is first shown and the overview closing animation to
not expand the workspace to the correct size the first time it is

954131c1c8 overview: Sync grabs after running startup animation
In the nested session the startup animation sometimes fails, weirdly
that always happens to me when running a freshly built gnome-shell the
first time. The reason it fails is that mutter fails to aquire a pointer
grab from the xserver, XIGrabDevice() is unsuccessful.

A simple workaround for this race condition in the xserver is to just
grab the devices a bit later, that is after the startups animation
instead of before it.

This was also tested with disabled animations, and seems to work just as
well in that case.

e7780623fe dnd: Don't use transformed size to calculate parent scale when restoring
Some drag actor parents might change their width to 0 after the drag
actor has been removed. If the drag is now canceled and the drag actor
is animated to return to the current parent position and scale, this
scale can not be determined and falls back to 1.0. This might be wrong
and can result in the drag actor being too large/small at the end of the
return animation.

To avoid this calculate the scale of the parent by recursively
calculating the product of its parents individual scales.

4e83aaf850 workspace: Extend clip when animating from window picker to app grid
We want to clip the Workspace actor in the appGrid state of the overview
in order to make sure windows that overflow the monitor don't spill out.
So far we had commit b1970b95b8 for that.

Now since the last commit, window previews always slightly overflow the
allocation with their icons. That means a part of the window icon gets
clipped away as soon as the transition to the appGrid starts, which
looks weird.

Fix that bug in the transition by slightly extending the clip downwards
when animating between the window picker and the app grid state. The
extra height we extend the clip by is controlled by the overviewState,
which means we extend the clip by the full icon overlap in the window
picker state, but don't extend the clip at all when in the app grid
state.

the overview, and the title and close buttons of those windows are only
visible on hover, so we can show them above anything if we want.

On both primary monitors and secondary monitors, there's a certain free
space available towards the bottom edge of the monitor (on the primary
monitor we show the dash there, and secondary monitors just scale down
the Workspaces). We can make use of this by checking how much free space
there is available from the bottom edge of our allocation to the bottom
edge of the monitor, and then aligning the window previews to make full
use of this space.

So stop adding any padding to the edges of the Workspace, which will
make the windows a lot larger and completely fill the Workspaces
allocation.

The left, top and right monitor edges should always be far enough away
to accomodate the close button and hover scale-up of the window. Only
with the bottom edge of the monitor we have to be a bit more careful
(the overflowing height of the window title is quite big), so there we
check if enough free space is available. If there isn't enough free
space, we simply apply a bit of bottom padding again and shift the
window up.
