Currently the box-shadow is rendering is done like this :
The first time we want to render a node that requires a box-shadow, St
creates an cogl offscreen surface of the size of the allocation and
renders the box into this offscreen buffer using modulation on the
alpha channel, this buffer is then blurred according to the CSS
parameters.
The problem with this method is that every time an StWidget is
resized, its box-shadow offscreen buffer has to be resized and
therefore rendered and blurred.
This patches propose an optimization for this use case by rendering
the box-shadow only once but at a size that is independent of the
StWidget's size. Then every time we need to paint this box-shadow, we
just render this offscreen buffer using a 9-slices.
This method only works when the allocation of the widget is bigger
than the minimum shadow size on which we can apply a 9-slices, that is
given my the radius of the corners. If the allocation is smaller than
this minimum size, we then fallback to the fully render/blur the
shadow (like before this patch).
The duality of the Clutter's key focus and mutter's window focus has long been
a problem for us in lots of case, and caused us to create large and complicated
hacks to get around the issue, including GrabHelper's focus grab model.
Instead of doing this, tie basic focus management into the core of gnome-shell,
instead of requiring complex "application-level" management to get it done
right.
Do this by making sure that only one of an actor or window can be focused at
the same time, and apply the appropriate logic to drop one or the other,
reactively.
Modals are considered a special case, as we grab all keyboard events, but at
the X level, the client window still has focus. Make sure to not do any input
synchronization when we have a modal.
At the same time, remove the FOCUSED input mode, as it's no longer necessary.
We can easily implement much of the same behavior ourselves by
keeping track of Clutter's focus events. Reintroduce heavily
modified FocusGrabber to do the work for us.
This will temporarily break when the user selects a window until
we can make gnome-shell automatically set the stage focus.
This also removes our only use of focus grabs, so remove those
as well.
ScreenShield: when the user goes idle, check for active before pushing a modal
We can't assume "isActive implies isModal", so there is a risk
of pushing a modal that nothing else will ever pop, because we
take the early return and don't activate the user active watch.
_updateIcon should not attempt to sync any active connections, as the
icon-changed signal can be emitted in response to something done during
_syncActiveConnection. In the case of VPN, removeActiveConnection would
cause an icon-changed signal to be emitted immediately, but the state
would not be updated, causing us to call removeActiveConnection over and
over.
Explicitly sync all active connections when we know it needs to be done,
and simply make _updateIcon synchronize with the current device's icon.
background: fix asynchronous management of background loading operations
This fixes a blue background being drawn when switching the monitors
configuration using hardware keys
(clone/multimonitor/external/internal).
The problem is that the shell gather all background loading requests
under the same meta_background_load_file_async call using one
GCancellable (the first one to come). So when the shell receives a
batch of 12 or so XRandr events, it creates 12 new background managers
which end up trying to load 12 times the same background picture. All
of these requests are batched into the same
meta_background_load_file_async using the first GCancellable received
on the first request. Unfortunately, when the first request is
cancelled by the following event indicating a new monitor setup, all
of the background picture requests are dropped on the floor, and
nothing gets loaded (hence the blue screen background).
It turns out that picking a 3200x1200 scene on notebook chipsets
every time the mouse is moved isn't exactly the fastest thing. Defer
picking to an idle to ensure that it won't get in the way of keeping
up with mouse events.
network-agent: Remove prototype of unused function
This causes a debug SpiderMonkey build to fail when it throws an
exception for the missing symbol, but doesn't properly return FALSE
when executing the script.
The code that checks for various conditions is confusing and
undercommented. It appears one of the recent refactorings
inadvertedly inverted the sense of the 'hidden mountpoint'
check, and caused autorun to not work for anything that does
not have a 'native root' - which is pretty much all volumes
implemented by gvfs.
Commit d6cace32 introduced a typo in the left/right arrow side
calculation code that causes in most scenarios (where the monitor
width is greater then the height) to not flip the box when it doesn't
fit inside the monitor.
If the drag action ends after something else has put the screen shield
into a different state we can end up in an inconsistent screen shield
state where the whole thing is empty.

loginDialog: Move the session list to a PopupMenu
There are some issues with the existing session menu. First, it looks
kinda bad. It seems like it's hanging around there, but it doesn't really know
what to do with itself.
Second, when it expands down it requires that the buttons below move
down with it. This kind of movement is awkward and looks a bit weird.
Third, its current position makes the "dialog" tall and unwieldy when
you add things like messages for fingerprint readers or authentication errors.
This commit moves the session list to a menu behind a button to address
the above problems.

ui: move AnimatedIcon out of panel.js
The class is generally useful, so it only makes sense in panel.js
for historical reasons. Because other parts of the code are
using it, though, problems are cropping up that require a
workaround like:
placeSpinner: function(...) {
/* This is here because of recursive imports */
const Panel = imports.ui.panel;
Panel.AnimatedIcon(spinnerIcon, WORK_SPINNER_ICON_SIZE);
...
}
This commit moves AnimatedIcon to its own file so we can drop that
workaround.
When the osd window is hidden based on the timeout, it accidentally
left the timeout ID in place. When a subsequent switcher popup came
up, it thought the OSD window was scheduled to be hidden and tried
to re-hide the actor. This caused the tween to be run along with
an extra call to enable_unredirect_for_screen.

st: Be more forgiving when calling get_theme_node() on unstaged widgets
While it is obviously still an error to call get_theme_node() on a
widget that hasn't been added to the stage hierarchy yet, asserting

likely the most frequent reason for crash reports. Just accept that
there'll always be code paths where we can hit this case and make
it non-fatal.

messageTray: Ensure notifications are focused after they are expanded
If we focus notifications before they're expanded, the body and action

network: Simplify connections to the firmware signal
The status item will go away soon, so make sure the one-time
fire is given its own function. At the same time, only connect

No class in here has this.carrier as a property. Presumably, this was
meant to be this.device.carrier, but since this code is going to be
rewritten soon anyway, might as well just junk the never-working
code for now.
In order to have event descriptions on multiple lines, but still
maintain proper alignment with the day and time strings, refactor
the whole event list to be one big table. Headers are implemented
as spanning cells, and uneven spacing is a mix of row/column spacing
and cell padding.
In BlueZ 4, Authorize() was used to authorize both service

have been split into AuthorizeService() for services and
RequestAuthorization for JustWorks devices. Adapt the
Bluetooth code accordingly.
This can be more easily achieved by listening for changes to the
device's active-connection property. VPN will still need support to
track active connections, as it does not have an associated
device. But as VPN can track multiple active connections, the names
"set" and "clear" don't quite fit. Rename them to the more-standard
"add" and "remove".
