This commit adds a grayscale effect to the magnifier, similar to
the lightness, brightness and contrast effects that are already there.
The effect is configured with the
org.gnome.desktop.a11y.magnifier.color-saturation setting, which
can take values from 0.0 (grayscale) to 1.0 (full color).

When connecting to virtual machines with usb-device redirection, such as Spice
enabled vms, automount may get in the way. Specifically if auto-usbredir is
enabled in the vm-viewer, then the usbredir code and the automount code race
for who gets to the device first.
If the automount code wins the race this is a problem, since usbredir causes a
device-disconnect (iow the usb mass storage driver sees an unplug), so in the
end usbredir always wins, and we end up with a non clean potentially corrupt
filesystem. Also see:
https://bugzilla.redhat.com/show_bug.cgi?id=812972
There for the need exists to be able to inhibit gnome-shell's automounting,
since all other inhibits run through gnome-session, I've chosen to do the same
for the automount-inhibiting. I've also submitted a patch to gnome-session to
reserve flag value 16 for this, see bug 678595.
This patch adds support to gnome-shell to honor this new inhibit flag.

The log messages about presence changes unnecessarily cluttered the

When selecting "Open Calendar" in the date menu, the configured

By disconnecting the 'notify::connection-status' signal as soon as the account
is disabled, we were missing the signal telling us when the status was moving
from CONNECTING/CONNECTED to DISCONNECTED and so the status icon was never
updated.
What we really want is to disconnect the signal when the account is removed
from the account manager as we don't care about it any more.

Use our native JS error system in the "extension system" API, only
using the signal/log-based error reporting at the last mile. Additionally,
delete the directory if loading the extension failed, and report the error
back over DBus.
https://bugzilla.gnome.org/show_bug.cgi?id=679099
Instead of using the 'extension-state-changed' signal to relay errors,
use DBus's native error mechanism to inform the method caller that the
call has failed. This requires making the method actually asynchronous
so that we don't block the browser, which is stuck waiting for a reply
from the browser plugin. To ensure this, we need to modify the browser
plugin API to ensure its extesion installation method is asynchronous.
Additionally, this lets us remove the awful, broken hacks that we used
when a user clicked the "Cancel" button, replacing it by a DBus return
value.
https://bugzilla.gnome.org/show_bug.cgi?id=679099
When the extension downloader was originally designed, the information
downloading part was inserted at the last minute, along with the modal
dialog as a security feature to make sure an extension didn't silently
get installed on the user's machines either due to a security issue in
the browser-plugin, or an XSS issue on the extensions website. Correct
the mistake I made when writing the code; instead of dropping an error
on the floor, log it correctly. This "bug" has already bitten a number
of users who forgot to configure proxy settings in the control center.

We strongly expect applications to use the same values for the
'Title'/'Icon' fields in their search provider .ini file as the
'Name'/'Icon' fields in their .desktop file. Rather than requiring
applications to duplicate those fields, allow them to specify a
'DesktopId' field instead to point to the corresponding .desktop
file, which makes it possible to ship search provider files without
translatable strings (which is nice given that merging translations
into search provider files lacks a standard rule).

Use the ShellMountOperation dialogs we have to implement a DBus API

Wait until the completion of the mount operation before dismissing the

Only apply the allowAutorun flag for transient notifications, not for
mounts that end up in the resident notification well.
Also, stop looking at volume.can_automount() here, since we already
checked that previously in the mounter, and allowAutorun is enough.
https://bugzilla.gnome.org/show_bug.cgi?id=660595
Previously, a volume was being ignored from autorun if one of these two
conditions were met:
- its mount root file had a native scheme and was mounted in a
non-hidden location
- it had a volume that could have been automounted, and had a flag set
by the shell to allow autorun
In order to effectively ignore volumes that we don't mount ourselves
from our notification system, we have to meet both conditions at the
same time instead.

This is a fallout from some changes in MessageTray.Source, which now
requires either defining the iconName/iconType properties on it, or

method to create the icon actor on demand, to avoid any case when the

The dependency chain spirals out from folks->zeitgeist->xapian...and
I'm really not interested in pulling in all of that into the core

There is work on splitting out contact search into gnome-contacts; I'd
add a bug link but Bugzilla is down.
When the shell takes control of the screen (for example to show

There is a race if a channel is invalidated during its preparation: the
'invalidated' signal is already emitted so the Shell will never notice.
We fix this by simply checking if the channel is already invalidated when

support approving one channel at the time.

Initially, extensions were loaded after they shell had fully created

A large amount of extensions have something like this in them:

we did check for NoDisplay on the app item itself, we didn't check against

_startTimer adds a tweener to implement the description countdown, which

Currently we only connect to the 'notify::n-workspaces' signal the
first time the overview is shown, which means we will miss any
changes to the workspace layout in the meanwhile.
In particular, the decision of whether the workspace switcher should be
shown is taken before the dynamic workspace handling takes over, and is
thus based entirely on the value of the num-workspaces user preference
rather than the actual number of workspaces.

explicit that the signal handler won't ever be disconnected).

We hide the content around displaying new search results to prevent

This patch works around that issue by saving the key focus and

Tweener uses a clutter timeline to manage all active animations
running at a given moment. The timeline is mopped up when no
animations are going any more.
Clutter requires timelines to have a finite duration, but since
animations can happen at any moment, no fixed duration can
accomodate the shell's needs.
To combat this problem, the tweener code picks a relatively
long duration: 1000 seconds. No string of animations should take
that long, so, in theory, that should be good enough.
Unfortunately, this tactic fails, in practice, when the user
suspends their machine, or VT switches. An animation can take
much longer than 1000 seconds (~16 minutes) to complete in those
cases. When the user resumes, or VT switches back the timeline
completes immediately (since it's already late) and tweener
never notices that the timeline stops ticking.
This commit changes the tweener timeline to automatically loop
back to 0 after completing, so that despite its fixed duration
property, it effectively never stops. Since the timeline loops,
its concept of elapsed time no longer increases monotonically,
so we now ignore it and track time ourselves with
GLib.get_monotonic_time().

the actor to be visible so we shouldn't set it reactive either.
