The portal helper is rather sensitive because potentially-hostile Wi-Fi
networks can decide to launch it whenever they want (by blocking the
user's connection to the nmcheck domain) and load whatever web content
they want into it. So having this unsandboxed is really extraordinarily
risky. Previously it was a risk we had to accept, because WebKit did not
have a web process sandbox, but now it does. So let's bubblewrap all the
things!

Commit 147a743d8d moved the suspend and power-off actions into
the submenu that contains the log-out and switch-user actions,
but did not update the submenu visibility logic to account for
the additional actions.
As a result, the submenu is hidden when log-out and switch-user
are unavailable (like on the login screen), even if suspend and
power-off are enabled.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2169
While gnome-shell will now check for extension updates, the checks
are performed infrequently. Opening the Extensions app implies that
the user's current focus is on extensions, so it is an appropriate
time to schedule another updates check.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
Now that we can download, apply and display extension updates, it is time
to actually check for updates. Schedule an update check right on startup,
then every 24 hours.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
Now that we have support for extension updates in the shell, we
need some place to display the updates to the user.
As we are establishing the Extensions app as the primary way for
managing extensions, it's a natural place for that functionality.
Show which extensions have updates available, and offer a log out
button (so gnome-shell can apply the updates when logging back in).
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
Until now, it didn't matter whether an extension was installed in the
user's home or system-wide. However with support for uninstallation,
there is now a significant different, as that action is only available
for user extensions.
Account for that by separating extensions by type, so that users don't
have to second-guess which extensions can be fully-managed and which
appear as part of the system.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
The newly added expander gives us a place where we can display
more details without cluttering the interface.
Take advantage of that by including the extension website, version
and author.
(Author is in the mockups, but will not actually be shown until
the extensions website is changed to include it in its metadata;
however best to have UI and string in place for the freezes)
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
The description can be useful information, but also increases the
visual complexity of the extensions list. Move it into a hidden
details area that can be expanded, which unclutters the interface
while keeping the information readily available.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
The current fixed two-line label requires a custom widget, which
make moving to a widget template harder.
As the description will soon move elsewhere anyway, just go back
to a single line with a standard label for now.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
Extensions can have a major impact on stability and performance. Now that
the tool will become the main way for users to manage their extensions, it
is an appropriate place to warn the user of that risk.
Add a small info popover to the headerbar to display that warning, together
with the previously removed hint of where to go for finding new extensions.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
Currently when the extensions list is scrolled, it is possible to
keynav out of view, as the scrolling doesn't follow the key focus.
Hook up the adjustment to fix that.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
Currently the main window is a plain Gtk.ApplicationWindow that is
built and managed from within the application.
As the application becomes more complex, it makes sense to decouple
the two and handle the window from a separate ExtensionsWindow class.
Not least this is a prerequisite of using a widget template for the
window.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
GNOME Software will remove its extension support, so we should stop
referencing it in addition to extensions.gnome.org.
In fact, the placeholder is not the best place to hint at where new
extensions can be found, as the user will never see it in case the
distribution includes pre-installed extensions.
So remove the hint altogether, we will add it back in a more prominent
place later.
With the whole placeholder now being much lighter, we can stop dimming
the remaining elements.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1968
If all password entries in dialogs are hidden, there is either an entry
that has visible characters or no entry at all. That means we don't have
to show the caps lock warning at all, so hide it.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/942
Since the headlines of the dialogs now use a much larger font, the
strings need to be shorter so they won't be ellipsized. So use a shorter
strings for those titles and also adjust the title-strings of the
notifications sent by the NetworkAgent to be consistent.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/942
Since the wiggle effect will be used by the redesigned prompt-dialogs
and we always want to use the same parameters, move those as defaults
for the wiggle function to the util.js file.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/942
Since the caps-lock warning adds a lot of spacing to dialogs and the
lock screen, hide it by default and only show it when necessary. To make
the transition smooth instead of just showing the label, animate it in
using the height and opacity.
Also add some bottom padding to the label so we can show or hide that
padding, too.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/952
The caps-lock warning is more related to entries than dialogs and is
also used in gdm, which is not realated to dialogs at all. Rename the
css class to caps-lock-warning-label and move it to the entry
stylesheet.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/952
The Animation class inherits from St.Bin and manages the scale factor
in the image loading, but the widget size doesn't change and doesn't
depend on the scale factor so when the scale factor is different
from 1 the widget size doesn't match the image size.
This patch resizes the Animation widget using the scale factor so the
widget will match the animation images sizes.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1746
Now that we have a way to check for updates and download them, we
should actually apply them as well. Do this on startup before any
extensions are initialized, to make sure we don't run into any
conflicts with a previously loaded version.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/945
While it is possible that an extension has a newer version available
than the previously downloaded update, it's more likely that we end up
downloading the same archive again. That would be a bit silly despite
the usually small size, so we can either use the metadata from the
update, or exclude the extension from the check.
The latter is much easier, so let's go with that for now.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/945
Currently the method installs updates instead of merely checking for
them (or it would do, if it actually worked).
This is not just surprising considering the method name, the whole idea
of live updates is problematic and will not work properly more often
than not:
- imports are cached, so any local modules will stay at their
original version until a shell restart
- GTypes cannot be unregistered
So change the method to only download available updates, and set the
extensions' hasUpdate state accordingly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/945
The current support for extension updates is half-baked at best.
We are about to change that, and implement offline updates similar
to gnome-software.
As a first step, add a hasUpdate property to the extension state
which will communicate available updates.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/945
Since a11f417cd0, both drag and scroll
gestures are added to Main.layoutManager.overviewGroup actor, while
previously drag gesture was added to Main.overview._backgroundGroup
instead. Since we cannot use 2 different actors for dragging and scrolling
anymore. just disable the swipe tracker while dragging a window.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2151
Since the orientation lock menu entry is a proper menu entry instead of
a icon-only button now, we also show a description-text for that entry,
so update this text depending on whether orientation is locked or not to
better reflect what clicking the menu entry will do.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/964
Since we don't really know what the buttons we're adding to the dialogs
are about, we can't configure a button to "be clicked" when the escape
key is pressed. So add a separate escape key handler to fix that, return
-1 and abort the request.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/961
When updating the buttons of the mount dialogs, compare the new buttons
to the old ones and only create new buttons in case something changed.
This makes sure key focus isn't reset or lost unnecessarily while a
dialog is opened.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/961
Since there is a generic layout for dialogs like that now, use it. Also
remove the functionality of focussing a window when clicking a list
item, it's not discoverable at all and pretty unexpected.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/961
On Wayland, the display server is the Wayland compositor, i.e.
`gnome-shell` itself.
As a result, we cannot spawn `gnome-shell-perf-helper` before
`gnome-shell` is started, as `gnome-shell-perf-helper` needs to connect
to the display server.
So, instead of spawning `gnome-shell-perf-helper` from the perf tool,
start it from `gnome-shell` itself.

When do-not-disturb is enabled, non-critical notifications will not
be shown as banners. It therefore makes sense to indicate that state
to the user, so they don't accidentally miss notifications.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/239
Currently the indicator pad requests a size of 0x0 if the corresponding
indicator is hidden. Right now this is enough to balance out the indicator,
but it won't be when we add spacing to the parent container.
Properly hide the pad with the indicator to avoid that issue.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/239
We've had the ability to temporarily disable notification banners
all the way back to 3.0, but we stopped exposing it in the UI with
the 3.16 notification redesign. With the message list being more
concise nowadays and the "Clear" button reduced to a single icon,
we now have space for a "Do Not Disturb" switch again.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/239
We try to make the OSK 1/3rd as big as the monitor. On landscape
layouts we usually get away with it as there's plenty of horizontal
space to enlarge the OSK while keeping the OSK aspect ratio.
In portrait layout, the horizontal space is a lot more scarce so
it means we'll still have plenty of space after making the OSK as
wide as it can possibly be, which will look as odd blank space in
the OSK panel.
In order to fix this, let the OSK panel height be less than 1/3rd
the monitor size if we are dealing with portrait layouts.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/2132
It will happen before next map anyway, and most notably at times
actor sizes produce correct results.
Fixes oddities in emoji pager visibility after showing the emoji

It is already scheduled to be set on first map. Doing so here triggers

This functionality always suffered from discoveribility
problems, and now that the folder dialog can rename the
app folders, there's just no reason to keep it.
Remove the rename popup.

Now that the folder dialog handles the adaptToSize workaround,
there is no need to propagate the call throughout the class

Now the the folder popup behaves like a dialog, it must be
above the app grid, and not be affected by the scroll view
translation.
Add the folder popup to the AllView itself, instead of the
internal Shell.Stack that is inside the scroll view.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/896
Make the AppFolderPopup behave much more like a dialog than a
popup itself. To do that, remove the BoxPointer and replace it
by a StBoxLayout. The dialog is is also bind-constrained to the

Since the overview search results now have a dark background layer, we
can brighten the background image a bit again. As a factor we use 0.5,

If a new SwitcherPopup is created and there are no windows or apps to
switch through found, instead of returning from _init(), still
initialize the SwitcherPopup and let the check in SwitcherPopup.show()
return false to terminate the popup.
In both cases, with or without the return statements,
WindowManager._startSwitcher() will call SwicherPopup.destroy(), which
will try to disconnect signal handlers, destroy actors etc. Now if the
constructor can't finish creating the popup, some of the functions
called from _onDestroy() will fail and throw errors.
One of those cases is when window-switcher is limited to the current
workspace, and a WindowCyclerPopup is initiated on an empty workspace.
Because this._highlight hasn't been created, _onDestroy() will fail when
trying to destroy the actor of this._highlight.
Also, the actor of this._switcherList will not get destroyed in case
show() returns because this._items is empty. For example, this will
happen when a new AppSwitcherPopup is initialized with at least 1
running app, but 0 windows on the active workspace.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/168
When pressing the menu key to show the popupMenu inside a ShellEntry,
the menu is currently aligned with the end of the entered text, this
causes a bug in case the text is overflowing the width of the entry: The
menu will be shown outside of the entry field, because it's aligned with
the (invisible) end of the text.
Fix that by simply aligning the popup menu with the cursor of the entry,
which is a behavior that makes sense when pressing the menu-key anyway.

`MessageDialogContent.messageBox` is not really needed and was only
needed to show icons, which is now no longer supported. The styling can
also be done using other CSS classes and this makes it a bit more
straightforward to add actors to the MessageDialogContent.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/886
Since MessageDialogContent.messageBox is going to be removed in a
subsequent commit, move the parts where it's used out of messageBox and
into the contentLayout instead. This will introduce wrong spacings in
some dialogs, which we're going to fix when implementing the redesigned
individual dialogs.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/886
Since the last commit we set the gicon property of StIcon to NULL if an
empty string was given when setting the icon name, this means
`st_icon_get_icon_name()` will return NULL instead of an empty string.
When `getIndicatorIcon()` returns an empty string, the icon_name
property will now be set to NULL, so compare it to NULL here.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/888
Animating the icon spring using the `translation-x/y` properties instead
of the `x/y` properties avoids relayouts. There are still other non-icon
actors moving, but it's a big improvement.
Before: 595 relayouts per spring
After: 94 relayouts per spring
Reducing relayouts reduces reallocation, which reduces CPU-intensive
JavaScript execution.

String.prototype.substr() doesn't support a negative length value

Commit 24e631ffe2 changed the shield animation to use translation
instead of position.
However once the shield is raised, only an animation will lower it

Fix this by resetting the translation-y property in that case.

Since commit 90a08ba0b6, we only open a network secret dialog immediately
in response to user action, and show a notification otherwise.
While for the actual request VPNs are handled separately from other connections,

with the other types there, or we fall through to the default 'invalid type'
exception.

Now that both ThumbnailsBox and WorkspacesDisplay use single adjustments for
controlling indicator and scrolling, create the adjustment in OverviewControls
and pass it to both objects, effectively syncing indicator to scrolling.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/821
Instead of having a scroll adjustment in each WorkspacesView, and using the
one from primary screen in WorkspacesDisplay, have just one adjustment in
WorkspacesDisplay, and sync the changes between WorkspacesView.
This will allow to share the adjustment between WorkspacesDisplay and
ThumbnailsBox in the next commits.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/821
Instead of using the 'y', which queues a full relayout and
thus forces effects to be reapplied, use the 'translation_y'

The screenshot code has a fair bit of nested callbacks, which means

We currently handle the case where the indicator itself is disabled
(read: hidden), but not when the entire top bar is invisible (for

Use the new StPasswordEntry for password entry fields
and remove all direct handling of clutter text of the entry
via clutter_text_set_password_char to show/hide the password

will allow to show/hide the password present in the field to
the user in subsequent commits.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/619
shellEntry should not need to query the clutter-text directly

shellEntry can easily determine a password-entry by querying

Since commit 87e60ed97843, geoclue no longer pretends that authorization

Just like switcher popups, popup menus don't play well together with
system modals, and generally have a lower priority. So just like
switcher popups, close popup menus when a system modal dialog pops
up.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1536
As system modal dialogs may open without user interaction (for instance
polkit or network agent requests), it is possible for them to pop up
while the app/window switcher is up.
The current result of having both up simultaneously is clearly broken,
so we can either dismiss the popup or prevent the modal dialog from
opening. Assume that the dialog indicates a more important action and
should therefore take precedence, so go with the former.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1536
Since both the `_items` object and the `_allItems` array include the
same items, the difference between those variables seems unclear. The
real difference between them (except the different data type) is that
`_allItems` is ordered in the same order as the visible grid, so rename
`_allItems` to `_orderedItems` which makes that more obvious.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/799
We have three interactions with an extension's prefs module:
- we import the module
- we call its init() hook
- we call its buildPrefsWidget() hook
The first two are one-time actions where we expect most getCurrentExtension()
calls (local imports, initTranslations() etc.).
However it's still possible that the extension will use the utility function
in buildPrefsWidget() as well, either directly or via other functions like
getSettings(): Make sure getCurrentExtension() returns the correct extension
in that case, not the last one whose preferences were initialized.

The icon grid currently sorts icons by their names. When creating new

We want extended keys to have the same size as their parent key,
but this is currently broken and the keys end up with their
parent key's preferred size (which is smaller than its allocated
size).
This is due to the way ClutterActor's width/height properties work,
which only return the "real" (i.e. allocated) size when the allocation
is valid, and fall back to the preferred size otherwise.
As changing an StWidget's hover state involves adding or removing
the `:hover` pseudo class, this is currently always the case.
Creating the extended keys first means the keyButton's allocation
is probably valid, so do that.

Mutter and Clutter was changed to pass around the current target

While still leaving them unused, pass around ClutterPaintContext and
ClutterPickContext when painting and picking.
The reason for splitting this change up in two is to make it possible to

When commit c6cea277e replaced Shell.GenericContainer, the check
whether the required width exceeds the avilable width was changed
from using the minimum widths of items to the natural width of the
scroll view.
That doesn't work correctly, as the *natural* width may well exceed
the actually used width: SwitcherList bases its width request on
children's minimum sizes to force labels to ellipsize.
Fix this by using the minimum width of the scroll view's child instead.

It is true that delete is a javascript keyword, but that doesn't

When the extension system is loaded, create the

The whitelist is a list of well-known D-Bus names, which we then search

Since the notification message close button had no border, or mouse

button styling.

Currently when dragging an icon to the space above or below the appGrid
to switch pages, we do so very quickly without checking when the last
page-switch happened. This makes it hard to move icons to pages which
are not the first or the last one, since the other pages are skipped
very quickly.
To fix this, add a timeout of 1 second that blocks switching pages after
a page-switch using drag overshoot occured.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1693
We currently always switch app pages when a dragged app icon
moves outside the grid boundaries, regardless of any previous
page switches. This makes it too easy to switch multiple pages
accidentally, so add a small threshold that the icon has to
move back towards the grid before allowing another page switch.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1693
There's no need for a `inhibitEventBlocker` interface. Since we connect
to "open-state-changed" of our folders in the AllView anyway, we can
just make the event blocker visible while a folder is opened, and hide
the event blocker during DnD.
This allows keeping the eventBlocker reactive at all times and fixes an
issue where DnD to create a new folder is impossible if no folders are
present because the eventBlocker would not get inhibited.

Emitting ::drag-end after changing the slider value via arrow keys
was a cheap way to make the sound feedback work for keyboard input.
But now that the volume indicator plays the sound on ::value-changed
as well, we can stop doing that - after all, key presses aren't drags.
Besides that, this will make the limiting of feedback to actual volume
changes from the previous commit work for key events as well.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/53
gnome-settings-daemon doesn't play the volume change sound when
the volume stayed the same (that is, it is already at its maximum
or minimum). This looks like the right thing to do, so copy its
behavior.

Commit 8d4855f100 accidentally removed the volume change feedback

While those should be concise enough to fit, they may not where

Commit b779f6f728 added a check to filter out invalid weather forecasts.
However the check is currently done when creating UI for the forecasts,
which means we end up with fewer forecasts than we could display if any
forecasts are invalid.
We can avoid that issue by checking the validity while collecting the
forecasts, so do that instead.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1927
We currently always start with the current weather info, then append
forecasts. This is slightly confusing, as the only hint that the
first item is special is the past (and potentially "odd") time.
Stop doing that and base all items on forecasts.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1927
As we get closer to midnight, we show fewer forecasts than we could
fit, or none at all. It makes more sense to continue the forecasts
into the wee hours in that case, so only exclude past forecasts,
but not ones from following days.

Weather stations can have unwieldy long names, which don't fit the

In case of a very long location name, the label may take up all

Commit c899453800 lifted the requirement of switcher keybindings
to contain a modifier, however it is currently only possible to
finish it by letting it time out.
Improve that by also accepting space/enter key presses to confirm the
selection immediately.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1883
The noModsTimeout obviously finishes inside a timeout callback, which
means `global.get_current_time()` might return Clutter.CURRENT_TIME (ie.
0) when called inside it, because it's not called while handling an
event. This means when switching apps or activating a window, the
timestamp passed to `activate_window` may be 0, which is the reason why
the altTab switcher is currently broken when using modifier-less
keybindings.
Fix that by using `meta_display_get_current_time_roundtrip`, which
always return a valid timestamp, instead of
`shell_global_get_current_time`.

Remove setCurrentPage() function, introduce setCurrentPosition() instead,

We slightly delay showing the switcher popup to avoid flashing it
briefly in the common case of quickly switching back-and-forth

Since the mpris implementation of the notification tray supports showing
multiple notification (one for each player), it doesn't make sense to
have only one global property to store the message, since that only
allows referencing one message at a time.
Instead, handle the MediaMessages completely inside the scope of
`_addPlayer()`, this should allow showing more than one message again,
which broke with commit 4dc44304df [1].

When removing the last icon of a folder, FolderView first removes
the folder from org.gnome.desktop.app-folders.folder-children, then
proceeds to reset all its keys, which removes the relocatable schema.
That order of operations turns out to be problematic. Removing the
folder from 'folder-children' destroys the folder icon, which in turn
destroys the folder view, which throws a load of warnings in the
journal.
Fix that by removing the folder after resetting the schema keys. In
fact, what we're doing here is not using 'this' anymore.

The variable that holds the list of application icons is

The views (AllView and FrequentView) build a list of all applications
they contain. BaseView then diffs between what's currently added, and
what needs to be added, and removed.
This approach has a problem though: creating an AppIcon or a FolderIcon
connects to various signals, and we confuse the garbage collector.
When building the list of applications, instead of always creating new
icons, try to use already existing icons first.

GWeather.Info.get_value_update() may indicate that the forecast is not

If the clock is set to 12h, the AM/PM in the weather forecast times

While we support a reasonable list of layouts nowadays, we don't

When cancelling the PolkitAgent session before disconnecting the signal
handlers, we receive a "completed" signal where `gained_authorization`
is set to FALSE, which means we show an error message inside
`_onSessionCompleted()`.
This in turn means we show an error message every time we cancel a
session. In practice this wasn't really relevant so far since we only
destroyed the session when an actual error occurred before. Now that the
dialog supports empty passwords, we also call `_destroySession()` when
the user changes and no longer has a password set, and in this case we
want to cancel the current session without showing an error message.
So to fix this, disconnect the signal handlers before cancelling the
session, which makes sure we don't receive the last "completed" signal
in case we cancelled the session ourselves. This change also allows
removing `this._wasDismissed`.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/829
When a user has no password and a polkit authentication is started,
instead of blindly initiating the admin session, show the regular
"Authentication Requested" dialog (but without the password entry). This
makes sure that the user's admin session is only effectively started
after the user chooses to proceed with the authentication, which
provides an extra confirmation step that can be vital for critical
tasks.
To do this, we show the dialog inside `_onUserChanged()` right after the
dialog was created instead of calling `performAuthentication()` from
`_onInitiate()`. The bug mentioned in `_onInitiate()` is no longer an
issue since we show the dialog in all cases now anyway.
Ideally we should use a different wording than "authentication" when the
user has no password set, and use "confirmation" instead. However polkit
already sends the requests with such messages (e.g. "Authentication is
required to configure software repositories"), and it's important to
show those to the user, so this patch keeps the regular wording.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/829
Since `_destroySession()` is not only called before we try to initiate a
new authentication session with Polkit, but also when the dialog is
closed, it's currently possible that key focus is grabbed by the close
button after the dialog was dismissed and hidden. This is causing a bug
where after dismissing one of multiple queued dialogs, key focus goes
away and keyboard navigation with the new dialog is impossible.
Fix this by only resetting the UI of the dialog if the dialog is still
opened/visible at that point.

Just as with c35b4cede5, there's no

Modifying variables from an outer scope in functions created in a loop

The FolderView class is responsible for creating the 4-item

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good

ES6 allows to omit property names where they match the name of the

If an else block only contains an if statement, the two can be

to avoid lonely ifs.

The event blocker in AllView is responsible for stealing click events
from the icon grid and closing the folder popup. The event blocker is
kept unreactive when no folder popup is visible, and it's made reactive
as a response to the 'open-state-changed' signal.
Using this signal, though, is problematic. When opening an app folder,
the icon grid first opens space for the folder to fit in; during this
period, it's possible to click on another folder icon, and break the
icon grid state.
Make sure the event blocker is reactive immediately after clicking on
a folder icon.

Objects implementing EventSource should have some mandatory methods and
properties, we can ensure this by defining an EventSourceBase abstract
class.
So inherit EmptyEventSource and DBusEventSource from it making sure that
they implement all the needed methods, using native properties and
replacing the 'notify::*' fake signal emissions with proper object
notifications.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/563
Use GObject based objects for ModemGsm, ModemCdma and BroadbandModem.

Animation background is just wrapping a native GnomeDesktop BGSlideShow

Resizing effects are more finicky as other effects, as the actual
animation is delayed until we receive the ::size-changed signal.
However that signal may never be emitted if the window is destroyed
just after starting the size-change effect, in which case the effect
is never completed, blocking mutter from destroying the corresponding
window actor.
Address this by tracking when a resize effect is pending, and complete
the effect when appropriate.

In the xwayland-on-demand scenario, it may happen that Xwayland is
shutdown (causing a restart of ibus-daemon to drop ibus-x11) while
we are typing.
If we have a bit of bad luck, this will cause the IBusInputContext
to be disposed (due to its bus "closing") at a time when we have
an ibus_input_context_process_key_event_async() request on the fly.
As the object is disposed in between this would tickle JS (rightfully
complaining that it's been disposed under its feet) and make us pass
an actually NULL IBusInputContext to the corresponding _finish()
function (despite the IBusInputContext being still held alive by some
other refs). This will assert and abort in
ibus_input_context_process_key_event_async_finish() then.
To handle this, listen for IBusInputContext::destroy, and reset our
internal state, this way we can compare on the JS side that the
IBusInputContext is indeed an up-to-date one.

I've observed that UPower can occasionally report a charge level of 100%

Since polkit takes a few milliseconds from initiating the session to
emitting the "request" signal, don't introduce visual distraction by
hiding the password entry and showing it again a few ms later.
So start a timeout of 200 ms when we destroy a session and if no session
request (i.e. a request for a password-authentication) happened during
this timeout, hide the password entry.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/788
Since we don't know if polkit/PAM will request a password (emitting the
"request" signal) or use another authentication method like a
fingerprint after the current authentication failed, hide the password
field and make the "Authenticate" button insensitive after cancelling
the session, just like we do when creating the dialog.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/788
Set the key focus to the password field only after we got a request
(and therefore know that a password is requested) instead of using
`setInitialKeyFocus()`. This way we don't try to focus the password
field by default if we aren't showing it (e.g. in case the user has no
password or is using fingerprint login).
Also we have to move the call to `grab_key_focus()` to happen after
`_ensureOpen()`, because otherwise the ModalDialog will set the focus to
one of the buttons while opening itself.

Show the user avatar for all users, including the root user. The root

It seems like some recent change (maybe the move to a ClutterActor
subclass for AppIcon) broke the check whether the drag source is an
instance of AppIcon. While the drag source indeed is an AppIcon and
everything else works correctly, the check still returns false, which
breaks the creation of new folders using DnD.
Theoretically it makes sense that this doesn't work, because we're
assigning AppIcon using `var AppIcon =` and that will only get set after
`GObject.register_class()` finished, so accessing `AppIcon` inside that
function seems risky and is probably wrong.
Fix this by comparing to `this.constructor` instead of `AppIcon`, which
works fine and we know for sure exists at this point.

I have observed a client in the wild (Chromium again) set CanPlay to
false momentarily while it is loading the next song. Previously, the
code would close the player proxy in that case, meaning that after
playing one track, the MPRIS message would disappear and never come
back.
However, I think this use of CanPlay, while apparently not usual, is not
incorrect according to the spec. We should hide the message instead of
closing the player proxy.

In the wild we have buggy clients (notably Chromium 77 and earlier) that

it is expected to be, and logs a warning if not, then continues on with

Similar to the previous work-around, xgettext gets thrown off by

Xgettext learned about template strings now, which is good. However
it's still buggy, so instead of the "classic" xgettext issue with

This corrects weird-looking blending visible as it fades out when the

There's no noticeable change in performance, but in theory it should be
faster as text entries don't change at full frame rate. So stage redraws

The close dialog is added as a child to MetaWindowActor, and, in Wayland
sessions, since commit [1] MetaWindowActor applies a transformation
matrix which scales all it's children using the geometry scale factor.
Now because the dialog actor is not a window (i.e. a MetaSurfaceActor),
but a subclass of StWidget, the scale factor is also applied to the
properties of the dialog by StThemeNode, so we end up applying the
geometry scale twice to the close dialog.
Fix this by applying the inverted scale to the dialog, which leaves the
scaling only to MetaWindowActor. This means we also can't apply a pivot
point other than 0 to the dialog actor, so apply the 0.5-pivot point to
the `_dialog` child of the Dialog class (the actual visible dialog box)
and also perform scaling animations on this child.
[1] https://gitlab.gnome.org/GNOME/mutter/commit/fb9e8768https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/783
Remove all transformations from window actors after a window animation
was either cancelled or finished. Right now we only do that if the
transition finished successfully, which seems kind of pointless (it can
probably be historically explained because the callbacks inside the
"kill-window-effects" signal handler are connected to those
`*WindowDone()` functions though and the `*WindowOverwritten()`
functions were only added later in [1]).
This fixes a recent regression where a window animation would get
cancelled and remain stuck by switching workspaces. The regression
probably happened due to different behaviour of the `onOverwritten`
callback of Tweener and the `onStopped` callback of Clutter transitions:
For the workspace-switching animation the window actors get reparented
to a temporary container, which makes Clutter transititons emit
"stopped" (`clutter_actor_remove_child_internal()` stops transitions on
its children), while Tweener would continue the animation.

We currently only update the windows section when either the focus app changes,

In the case of bugs in a drag target's acceptDrop() function, it may

When accessing properties on ClutterActor for size and position there is
a notable access time overhead. This overhead adds considerable user lag
when opening the overview if many windows are open.
