We will now basically act as "policy provider" for thunderbolt
peripherals by using org.freedesktop.bolt service: when new
devices are connect and session is a unlocked user session
we will automatically enroll (authorize and store in the database)
them.
If new devices are connected but the session is locked a message
will be shown informing the user that the device needs to be
reconnected to properly work.
The org.freedesktop.bolt service is provided by the "bolt" daemon.
Currently the language options displayed pretty much mirror those of the
top bar keyboard layout selection popup. It may make sense in the future
to only list languages, and automatically switch to the enabled IMs that
the OSK can benefit from (eg. by filling in suggestions).
In the current code it could happen that we've menuItems and indicatorLabels
for sources that aren't anymore around, because in case a source is removed
we don't cleanup the their container objects.
Also, we should nullify InputManager's _currentSource when sources change
or it might point to some invalid data again.
So it could happen that we try to access an invalid menuitem or label
if a source change happens mentioning a source that has been deleted.

This D-Bus property was never been added here, which caused inconsistencies
under some scenarios (e.g. coming back from suspend) if some devices were
previously paired, since _sync() would then make the bluetooth menu visible
unconditially, because of the proxied property evaluating to 'false'.
Adding this to the D-Bus interface makes sure that it's no longer undefined
and returns the right value, fixing the bug.

The idea behind always showing the icon on the login screen is that

In anticipation of showing the system actions in
the search results, it is fit to move action
specific code to its own module in order to

https://bugzilla.gnome.org/show_bug.cgi?id=691900
The current behavior wasn't designed, but was introduced in commit
84efaac52b to work around technical limitations when we were still
using external tools like gnome-screensaver or gnome-session-quit
to handle the actions. Those limitations are long gone, so it makes
sense to make the actions consistent with the corresponding keyboard
shortcuts: Leave the overview when launching an application, and leave
it alone otherwise.

While we've always considered it good style to initialize JS properties,
some code that relies on uninitialized properties having an implicit

even though all warnings addressed here occur in conditionals that

It is possible to use the scroll wheel to adjust the volume without

Since commit 2c070d38, we add a ClickAction to the visible AltSwitcher

component grab when the first activates.
Currently we only drop the StButton grab on long-press, we also need
to cancel any initiated long-press on click.

Currently when the wifi selection dialog is open when the screen lock is

The top bar's network menu only supports a subset of device types
supported by NetworkManager. While not having lesser used options
in the menu itself is perfectly reasonable, not showing any network

Any network devices appear as top level items in the system status
menu, so on system with an unusually high number of devices, the
menu can end up exceeding the available screen height. While this
is a corner case, leaving important system actions unreachable is
bad. The system menu does not lend itself to scrolling, so handle
this case instead by summarizing sections ("n connections") where
the number of devices exceeds a threshold.

If Bluetooth is on but there aren't connected devices, the status in the

Let's make it really simple and ask user interactively, once. This
simplifies things for:
* Privacy panel of gnome-control-center as it doesn't have to filter
applications.
* Apps: If they are denied access, they can simply point users to
privacy panel of gnome-control-center since they can be sure location
access for the app can be enabled in there.
Also it's less annoying to user. Before this patch, if they denied
access to application, they had to keep doing that at least each time
they launched the application.
https://bugzilla.gnome.org/show_bug.cgi?id=762559
Alex told me that since it's not geoclue but rather GNOME-components
storing/accessing app permissions, it's better if we put it under
'gnome' rather than generic 'desktop' table.
While we could have implemented this already a while ago, this would
have been a completely false security mechanism since we had no way of
reliably identifying applications. Since now with xdg-app, we can at least
reliably identify bundled applications, let's give users a choice of
which applications in particular they are OK with giving location data
to.
While we still can't reliably identify system (non-xdg-app) applications,
it seems extremely unlikely we'll ever be able to do that (at least not
in the near future) so we'll have to trust them to not lie about their
IDs.
Next release of geoclue will take the ID of bundled application directly
from corresponding xdg-app metadata so bundled applications can't simply
lie about their IDs.
https://bugzilla.gnome.org/show_bug.cgi?id=762119
This class will be responsible for authorizing applications that try to

Any time estimates we can come up with are notoriously unreliable;
even on devices that report correct (dis)charging rates, any change
in workload, screen brightness etc. can throw our estimate off by
a huge amount. This is further compounded by bad firmware and battery
firmware which reports inaccurate data as neither Windows nor Android do
not use that data.
So instead, limit ourselves to only showing the current percentage
and leave its interpretation to the user.
As an added bonus, we end up with shorter strings that are less likely
to cause problems with ellipsization when translated.

If we detected that Bluetooth devices were setup, show the Bluetooth
menu so that users can easily turn Bluetooth back on.
This is a bit of a hack, as we cannot detect whether there is a
Bluetooth adapter at all when it's disabled, so we cannot tell whether
there were any Bluetooth devices setup, at some point. This state is
saved in the gnome-shell GSettings in the had-bluetooth-devices-setup
key.
Checking whether we saw Bluetooth devices at one point is a good
enough guess of whether there will be some in the future.

Instead of saving only the current input source when entering password

g-s-d has been taking care of this for us but in a very hackish way
that causes dconf writes on every startup and also doesn't handle
dynamic updates to locale1's properties which has become a problem now
that GDM keeps its greeter session running in parallel with users'.
To take care of this properly, this commit introduces a settings
abstraction with both system and session implementations. The session
implementation just wraps access to the existing gsettings while the
system one gets its values from org.freedesktop.locale1's properties.
https://bugzilla.gnome.org/show_bug.cgi?id=746288
The mode is never set after the removal of the bottom tray, so it
no longer makes sense to pass it to allowKeybinding(). We can also
safely remove it from the ActionModes flags altogether without
requiring a synchronized update with gnome-settings-daemon, as
the latter never used any flag value above LOGIN_SCREEN.
This used to be the style-class for status icons (i.e. icon-only
top bar items). It got unused a while ago when the class used
by status icons stopped using it - except for the keyboard indicator,
which set the class manually to appear as status icon despite not
being a real icon.
Now that the button highlight is provided by the .panel-button class
on a parent, the obsolete class results in a double border on the
keyboard indicator when active - just drop it from there as well
to fix.
Input method preedit text needs to be disabled on password entries
for security and usability reasons.
IBus 1.5.7 provides the signal set-content-type so that panel UIs can
handle these special purpose input entries:
https://github.com/ibus/ibus/commit/6ca5ddb302c9
Unfortunately IBus versions older than 1.5.10 have a bug which causes
spurious set-content-type emissions when switching input focus that
temporarily lose purpose and hints defeating its intended semantics
and confusing users. We thus don't use it in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=730628
Due to a typo we were always removing the first (index 0) connection
from the global list of connections instead of the correct one.
This resulted in some connections remaining in the shell's connection
list long after they were removed. In particular, this resulted in
multiple copies of a bluetooth connection appearing after suspend/resume
(when the device was readded and the cached connection list was
rescanned).
https://bugzilla.gnome.org/show_bug.cgi?id=740227
Normally users switch xkb input sources and ibus input sources.
But currently the first input source only is running. It's also good
to preload all ibus engines in the logging session so that users switch
input sources quickly without the launching time of input sources.
The following is the ibus change:
https://github.com/ibus/ibus/commit/cff35929a9https://bugzilla.gnome.org/show_bug.cgi?id=695428
Most of the code handles the sources setting being empty and
InputSourceManager.currentSource being null because previously the
"model" (i.e. the sources list) was kept in gnome-settings-daemon.
But this is fragile and since we're now the canonical place where the
list lives we can force it to never be empty even if the gsetting is
empty or contains only invalid entries. Adding the default keyboard
layout in that case is the safest thing to do.
https://bugzilla.gnome.org/show_bug.cgi?id=738303
All other submenus link to the corresponding settings, so we should
do the same for location - the privacy panel in this case, which now
sports a "Location Services" switch ...
https://bugzilla.gnome.org/show_bug.cgi?id=736542
Instead of calling out to gnome-settings-daemon we'll just implement
the switching logic ourselves and use mutter APIs that allow this
functionality to work both in X sessions and when we're a Wayland
compositor.
Switching IBus engines is done transparently as well just like g-s-d
used to do.
https://bugzilla.gnome.org/show_bug.cgi?id=736435
We don't really need this step as a separate method since all

The enums values of geoclue have gaps in them (so more levels could be
added in future) but enum values of settings don't have such gaps so we
gotta translate between them.
Since desrt says that enums as integers in gsettings are bad, we now
treat accuracy level settings as string.
This fixes the recent regression of geoclue only allowing geiop level
accuracy to apps.
https://bugzilla.gnome.org/show_bug.cgi?id=736479
Users can now toggle geolocation off/on from privacy panel of
gnome-control-center so we don't need to clutter the menu with a

https://bugzilla.gnome.org/show_bug.cgi?id=731122
All derived classes are already checking explicitly for action names
(FOO and FOO_BACKWARDS). mutter used to have a META_KEY_BINDING_REVERSES
flag for keybindings which required special handling of "shift"+FOO as
FOO_BACKWARDS, but this has been removed now, so this special handling
is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=732296
When this flag is set on a MetaKeyBinding, mutter will know that
the keybinding has an associated reverse keybinding triggered with
the shift modifier. However, an undesirable side-effect is that
gnome-control-center keyboard panel does not know that this 'shift'
is reserved for these reverse keybindings and cannot detect
conflicting bindings in this case.
This 'reverse' logic can now be handled at a higher level (in gcc keyboard
panel) so this commit removes it from gnome-shell so that they do not
conflict.
https://bugzilla.gnome.org/show_bug.cgi?id=732296
Now that mutter gives a way to check if a MetaKeyBinding was marked as
'reversed' or not, gnome-shell does not have to hardcode that a
MetaKeyBinding using a shift modifier is reversed, it can directly check
if the appropriate flag is set.
https://bugzilla.gnome.org/show_bug.cgi?id=732296
Since these settings are now going to be accessed by
gnome-control-center as well, its more appropriate for them to live in
gsettings-desktop-schemas.
https://bugzilla.gnome.org/show_bug.cgi?id=734483
Having the on/off setting be backed by a boolean in dconf makes sense
anyway but this is mainly to be able to remember the max accuracy set
before user disabled geolocation so that when they enable it next time,
we have the max accuracy level on same value as before.
There hasn't been a real need for this but now we are about to add
geolocation settings in control center and it'll be easiser for
control-center to simply toggle a boolean property rather than to have
to know about and deal with accuracy levels.
Later we might also want to add accuracy level settings to privacy panel
so keeping the accuracy level setting around still. However we no longer
support 'off' accuracy level as the new boolean property covers that.
This also implies that we no longer track available accuracy level,
which made the code a bit hard to follow/maintain.
https://bugzilla.gnome.org/show_bug.cgi?id=734483
Listen to changes in connectivity, and ask our helper to authenticate
when needed.
We don't have a URL to connect to yet (we will have when
the new NM API lands), so we use the default of trying
www.gnome.org (which is also more reliable because we can
recognize when the login is done)
https://bugzilla.gnome.org/show_bug.cgi?id=704416
Icons inside the menu are updated only for device state change,
but for the main device they also depend on connectivity (which
is a global property).
Add a public method to force an update of the icon, and call it
when connectivity changes.
https://bugzilla.gnome.org/show_bug.cgi?id=726401
We translate 'On' to available accuracy level but if available accuracy
level later changes, we don't update available accuracy level accordingly
and hence limit the accuracy of apps.
E.g if available accuracy level is 'city' and geolocation is enabled,
the max accuracy level would be 'city' and apps can't get higher than
that. Now if user plugs in GPS, the available accuracy level will change
to 'exact' but without this patch max accuracy level will remain to be
'city' and apps will not be able to use the GPS.

If geoclue reports that we can't aquire location, we hide the menu. This
