The time computation isn't just unnecessary in that case, it's likely
wrong as well: If we don't have a valid allocation, we may well end
up with a negative value, NaN or Infinity.
Now that redisplaying is a lightweight operation that only
adds and removes what changed, we can not be concerned about
redisplaying on folder changes.
Redisplaying will be necessary when custom order in the app
grid is implemented, in order to update not only which icons
are hidden, but also their position.
FolderView and AllView currently check if the item is
present in the BaseAppView._items map, in order to avoid
adding the same icon multiple times.
Now that BaseAppView._loadApps() has a different role --
it returns a list with all app icons, and BaseAppView
diffs with the current list of app icons -- checking the
BaseAppView._items map is wrong.
Make sure there are no duplicated items in the temporary
array returned by all _loadApps() implementations. Remove
the now unused BaseAppView.hasItem() method.
BaseAppView currently removes all icons, and readds them, every
time the list of app icons needs to be redisplayed. In order to
allow animating app icon positions in the future, however, we
cannot destroy the actors of the app icons.
Previous commits paved the way for us to do differential loading,
i.e. add only the icons that were added, and remove only what was
removed.
Make the BaseAppView effectively implement differential loading.
The BaseAppView.removeAll() method is removed, since we do not
remove all icons anymore. BaseAppView._loadApps() now returns an
array with the new apps, instead of putting them directly at the
BaseAppView lists.
Now that the three views follow the exact same loading routine
(remove all + load apps + load grid), we don't need each view
call loadGrid() directly anymore.
This is an important step in order to animate adding and removing
icons, since now we can diff old and new app icons properly.
Move all calls to BaseAppView.loadGrid() to a single one after
BaseAppView._loadApps(). Also add the underscore prefix, since
this is now considered a protected function.
frequentView: Use BaseAppView.addItem() and loadGrid()
FrequentView is another view that is slightly not unified with how
BaseAppView expects subclasses to load app icons. Instead of using
BaseAppView.addItem() and then calling BaseAppview.loadGrid(), it
adds the app icons directly to the icon grid.
Make FrequentView add icons using BaseAppview.addItem(), and load
the icons using BaseAppView.loadGrid().
Future patches will diff the old and new icons of views, in order to
animate them when necessary (e.g. adding an app icon to a folder, or
from a folder back to the app grid). In order to do that, all views
must be streamlined in how they load app icons.
Currently, FrequentView and AllView are already following the behavior
expected by BaseAppView, but FolderView isn't. Its icons are loaded by
FolderIcon, and FolderView doesn't implement BaseView._loadApps(),
which makes it impossible to diff old and new apps.
Move the app icon loading routine from FolderIcon to FolderView, by
implementing the _loadApps() method.

data: Flag in desktop file that gnome-shell can be started using systemd
As gnome-shell is a required component for GNOME sessions, gnome-session
will currently always try to autostart it. However as we are moving towards
using systemd's user instance for session startup, gnome-session should only
be responsible for launching the shell when either not running under systemd
or when we were built without systemd support.
gnome-session can detect the former but not the latter, so communicate this
via the newly added X-GNOME-HiddenUnderSystemd key in the .desktop file.
Our current Weather integration depends on poking around the app's
settings, which we cannot do when the app is sandboxed (as its
filesystem is "hidden away" in a container in that case).
So instead, use our own GSettings schema for the settings, and sync
it with GNOME Weather via a custom D-Bus interface.
`g_object_notify()` actually takes a global lock to look up the property
by its name, which means there is a performance hit (albeit tiny) every
time this function is called. For this reason, always try to use
`g_object_notify_by_pspec()` instead.
We currently assume that user icons are square, which is the case when
set by the users settings panel, but not enforced by AccountsService.
Handle that case by moving the pixel size back to the actor and using
an appropriate background-size style property of 'cover' (which means
the smallest dimension of the image is scaled to fit the desired size).
A generic, introspectable Shader effect is not only more flexible
than a shader actor, it will also make it much easier to turn
Lightbox into an actor subclass and replace Tweener with Clutter's
own animation support.

shellDBus: Use floats instead of percentages for OSD levels
Due to typecasting being done when converting floats to integers in
gnome-settings-daemon, a volume of 0.9% in g-s-d will end up as 0% in

volume indicator (the icon to use is determined by the shell using the
volume received from g-s-d).

AppIcon makes itself draggable, and handles the various DnD

Overview emit the appropriate signals.
However, when destroyed, the AppIcon does not try to finish
any drag operations that started. That causes the event

icons to outside folders.
Make AppIcon emit 'item-drag-end' when a drag operation

ci: Add eslint job to review stage
We have now reduced the number of eslint errors enough to add it to
the CI pipeline. There are still plenty of errors left though, so we
cannot simply run eslint and fail on any errors. So instead, run it
through a fancy script that:
- generates an eslint report using the "regular" configuration
- generates an eslint report using the "legacy" configuration
- creates a combined report with errors common to both configurations
When the pipeline is running for a branch or tag, the final report is
printed out and the job succeeds (we know there are errors left);
when the pipelne is running for a merge request, we fail if any errors
are reported for the lines modified/added by the MR.
GNOME apps use 'review' for the CI stage that generates and exports a
flatpak bundle after a successful build, so they need some other name
for anything that is checked before building; that's how we ended up
with the somewhat awkward 'source_check' stage (inherited from Polari).
But since the commit log check added a 'review' stage that runs pre-build,
use that for all checks that are performed before the build stage.
