Rework the count system in Source, to distinguish between the
normal notification count and the count of unseen/unacknowledged
notification. (A notification is considered unacknowledged until
shown, as a banner or inside the summary box pointer).
Includes some code cleanups and a test for multiple notifications
in the same source.
https://bugzilla.gnome.org/show_bug.cgi?id=681143
If a source is associated with an app, ignore the app name provided
by libnotify, as that is often garbage.
This fixes the "XChat-GNOME OSD" problem.
https://bugzilla.gnome.org/show_bug.cgi?id=681143
Reduce padding around persistent sources, and ensure that spacing
around resident notifications is only applied once.
Also, add some padding to the clock.

As description of the setting says, color-saturation ranges from
0.0 (grayscale) to 1.0 (full color), but the real outcome was the
opposite. The reason is that clutter provides a desaturation effect,
and color-saturation was passed directly to that effect. This patch
renames the effect and compute the desaturation value.
GetUserVerifier can only be called from the greeter session,
and fails with AccessDenied in all other cases. Also, calling it
hides the real error from OpenReauthenticationChannel, which
instead should be logged.
https://bugzilla.gnome.org/show_bug.cgi?id=680750
Unlike the fallback gdm UI, we do not indicate in the user list
whether a user already has an open session or not. This information
is useful, so use a spotlight effect similar to the running-app
indicator to mark logged in users.
https://bugzilla.gnome.org/show_bug.cgi?id=658185
We want to style user list items differently depending on whether
the list is expanded or shrunk; instead of manually updating the
items' style, we can just expose the :expanded style on the list
itself and use that in the CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=658185
The current animation time of two seconds may result in some
confusion, as the reason of the behavior only becomes apprent
when the auto-activating item becomes visible; make the animation
a lot faster and ease it out a bit.
https://bugzilla.gnome.org/show_bug.cgi?id=660913
Until the recent style changes, the same element was used to indicate
both item focus and progress for timed logins. As focus is now indicated
by the item's background style, rename the indicator from focusBin to
timedLoginIndicator and make some minor adjustments to better fit the
new style:
- move it next to the icon below the text
- give it a white color and a shadow
- update animation to grow from the left instead of the center
https://bugzilla.gnome.org/show_bug.cgi?id=660913
Rather than changing the text color to indicate hover and an underline
to mark the focused item, use the same semi-transparent white background
as in the overview.
https://bugzilla.gnome.org/show_bug.cgi?id=660913
gnome-session and gnome-settings-daemon rely on the screensaver
interface to know the locked state. Since gnome-screensaver is no
longer running, it's up to gnome-shell to provide it.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
When the screen shield is activated from the user menu, animate
it instead of showing it abruptly. Also, ensure that the animation
had time to finish before calling UPower to suspend, to avoid
showing it when resuming.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Track screen lock status in the message tray, and filter banner
notifications. The message tray is completely hidden when the screen is
locked, but exceptions can be made for individual transient notifications,
such as shell messages and the on screen keyboard.
Non transient sources are shown in the middle of the lock screen. Resident
notifications (such as those from Rhythmbox) are shown in full, while
persistent ones are displayed as icon and message count.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Track locked status and use it to provide a reduced version of
the panel in the locked screen. Accessibility, input sources and
volume menus are preserved, without the link to the control center.
Network, battery and user menu are reduced to pure indicators,
with no menu.
This is similar to the design but not exactly, because designers
in IRC said that network needs more analysis before exposing, and
because the design didn't account for a11y and IM (so the one menu
metaphor is not really appropriate).
https://bugzilla.gnome.org/show_bug.cgi?id=619955
The design calls for the curtain to appear in the gdm greeter too.
Implement this by having the screenshield manage the login dialog
(delegating its creation to SessionMode).
https://bugzilla.gnome.org/show_bug.cgi?id=619955
This separates the screen shield into two main screens. One is
the lock screen, and it is shown when coming back from idle status
and when failing authentication. The other is the actual unlock
dialog.
Moving from the first to the second is possible by pressing Escape
or by dragging an arrow on the bottom on the screen.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
This ensures that the screen shield is created at the right
stacking level, so the message tray is visible in the lock screen
(showing PAM messages, critical notifications and the on screen
keyboard)
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Ensure that the lightbox is above everything (including the screenlock
itself) when fading in - this allows for fading while showing the
unlock dialog. Also, don't pushModal again when already locked, or
we won't get out of it.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
When the screenshield is deactivated, instead of going back to the
session immediately, prompt the user for authentication.
This essentially reinstates what used to be provided by gnome-screensaver.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
We are replacing the gnome-screensaver module with with a screen shield
that is part of gnome-shell.
This patch fades out the screen on idle and shows a shield with a background
image when there is activity again. The shield can be removed with a key or
button press.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Add 'default' parameter to setButtons, that controls the binding
of Return (unless overridden) and applies the 'default' pseudo-class.
Currently it has no effect, but it will start having after the
login dialog redesign.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
To allow more than one summary icon actor for a source we split
the model of the source icon (which is iconName, if the default
implementation is used, or a GIcon otherwise) and replace
createNotificationIcon() with a generic createIcon(size). Also,
the actual source actor is split into a separate class, that handles
the notification counter automatically.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
The :reactive property is used on StButton to like the :sensitive
property on GtkWidgets, that is, to indicate that the user is not
(yet) expected to click the button, and therefore should affect
styling too.
This allows to remove some code at the JS layer.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Previous code would access the array element before checking that
the index was within bounds, and therefore cause a TypeError.
It wasn't noticed earlier because at least one visible children
is in each panel box in all session modes.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Destroyed modal actors should be completely removed from the modal
stack automatically, including leaving modality if needed.
This allows for destroying modal dialogs without calling close().
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Change visibleInFullscreen to be trackFullscreen. If true, visibility
is fully bound to fullscreen status, if false, no change is made.
This allows to avoid set_skip_paint(), while not messing with
visibility of actors that are sometimes hidden for other reasons.
The flag was reversed because only the panel uses it, so false is
a more useful default.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Make it possible to control the visibility of "Show/hide text" item

When setting an explicit size as we do currently, rounding errors
(for instance introduced by padding not specified in pixels) may
affect the parent's size allocation, e.g. making it shrink or grow
each time the size is reset.
Rather than taking care of possible rounding errors, set up focusBin
to take up the available width and use scaling for the animation.
https://bugzilla.gnome.org/show_bug.cgi?id=675076
When GDM was moved over to GDBus it dropped the libgdmgreeter
library and introduced a new libgdm library with a somewhat
different API.
The main differences in the API are:
1) open_connection is now implicit and automatic
2) conversations don't need to be started explicitly, they're
started just-in-time when verification is requested
3) The functions are split up between the client, and new
helper objects that correspond to the dbus interfaces
they were generated from (one for user verification,
one for greeter specific operations, and a couple more
that aren't used by gnome-shell).
4) libgdm supports reauthenticating in an already running
session, so user switching should now affect the users
session more like screen unlocking does.
This commit moves the shell over to the new library.

This makes sense, since we are covering input methods and keyboard
layouts in the same keyboard menu. The effect of this change is that
the ibus status icon no longer appears in the system status area.
Changing the number of workspaces while the popup was visible (which
happens when moving windows on the last non empty workspace) resulted
in a wrong layout. Fix that, by listening to workspace-added and
workspace-removed signals, and by always requesting an updated size
from the actor.
https://bugzilla.gnome.org/show_bug.cgi?id=679005
We connect to the IBus daemon asyncronously and use it to query info

The calendar grid is build by giving each element right and bottom
borders, all top-most elements a top border, and all left-most

appearing clipped on the left side.

While modal dialogs were attached to the parent's titlebar, it
made sense to leave the top of the parent window at full color.
With the new position of modal dialogs, it makes more sense to dim
the entire parent window, so we can use a combination of Clutter's
BrightnessContrast- and DesaturateEffect instead of our own custom
shader.

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:

By disconnecting the 'notify::connection-status' signal as soon as the account

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.

When the extension downloader was originally designed, the information
downloading part was inserted at the last minute, along with the modal

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

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).

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

When the appMenu is not available, for instance when no windows are

Now that all searches are async we can remove the code path for the

As shown in the previous commits, synchronous search is easily implemented
by the asynchronous search API. The only reason we still have a

and git log can keep our fossils safe if need be....
https://bugzilla.gnome.org/show_bug.cgi?id=675328
To allow this to happen, we need to make sure that we don't overwrite the

search failed.

Two nested scroll views were fighing with each other. The reason isn't

We hide the content around displaying new search results to prevent
flickering, unfortunately, one side effect of hiding an actor is
losing key focus if it currently is on the that actor or any

This patch works around that issue by saving the key focus and
resetting it back after displaying the new async results.

To avoid messing up St.Buttons' internal state with a pointer grab,

Currently, click and drop events are handled by each WorkspaceThumbnail

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().
This partially reverts commit

Bailing out of _sync() early if the application lost keyboard focus to

In the workspace-collecting code we add a check to avoid collecting a

The hide animation causes hover notifications for the actors inside the
boxpointer. PopupBaseMenuItems, in particular, grab the keyboard focus on
hover notifications to enable keyboard navigation on menus. This, in turn,

Since input events aren't useful while menus are animating we just prevent
them from propagating.

With the recent keynav changes, the keyboard focus can now move
away from the search entry while a search is active. While we
keep the focus entry style while a search is active, we set the
cursor visibility depending on whether the entry has focus. This
doesn't seem very logical, so always request to show the cursor
when we appear focused.
Note that at least for now we are just expressing intent, as clutter
never draws the cursor for unfocused entries.
When canceling a search pressing Escape while the focus is on the
search entry we clear the entry, set its text to the hint and go back
to the previously selected tab. Make this the behavior also for when
the focus is on search results and not on the entry itself.

The preferred way to unmaximize/untile a window is by using a drag

We will allow applications to hook into shell's search by registering

"search-providers" is a reasonable directory name for applications to

https://bugzilla.gnome.org/show_bug.cgi?id=663125
Currently, asynchronous search providers are expected to call
startAsync() in getInitialResultSet()/getSubsearchResultSet(),
which will trigger async mode until the search is canceled or
updated. Switching between synchronous and asynchronous mode like
this makes asynchronous search an implementation detail, but being
transparent to the searchDisplay means that certain optimizations
don't work as expected. Namely, updating asynchronous search results
causes flickering, and the automatic selection never focuses
asynchronous results.
So change the API to require providers being either synchronous (with
the current getInitialResultSet()/getSubsearchResultSet() methods)
or asynchronous (with asynchronous variants), and handle asynchronous
providers explicitly in searchDisplay.

renderResults() updates the results set, determines the number of

flicker-free rendering and control the selection - we want to keep
both features for asynchronous result metas which we are about to

An actor is removed from its parent after it emits the destroy signal,
so we can't just check if the notification stack has more than one
notification -- we need to check if there's a notification there
that is not the current one.
This was causing spew in the form of:
"this.notificationStack.get_children()[0]._delegate.setIconVisible
is not a function"
IconGrid items used to be square, so a single size value made
perfect sense. However, as contact search uses rectangular items,
using a single size is wrong - the allocated height ends up twice
the size of the visible height, which is particularly visible if
another provider displays results below contact results.
https://bugzilla.gnome.org/show_bug.cgi?id=670148
The correct way to make an actor having the same size as another is
a ClutterBindConstraint. Connecting to 'allocation-changed' fails because
the allocation might not change even when 'width' and 'height' properties do.
This is the case of Main.uiGroup, used as parent container for zoomed
window clones.
In lightbox.js we bind also the position because in principle it could change,
even if currently only fullscreen lightboxes are used.

The "extension" object is what I previously called the "helper" object.
It contains the extension importer object as well as the metadata object.
Things that were previously added on to the metadata (state, path, dir, etc.)
are now part of this new "extension" object.
With the new importer changes brought on by the extension prefs tool,
extensions are left without a way to import submodules at the global scope,
which would make them rely on techniques like:
var MySubModule;
function init(meta) {
MySubModule = meta.importer.mySubModule;
}
That is, there's now a lot more meaningless boilerplate that nobody wants
to write and nobody wants to reivew.
Let's solve this with a few clever hacks.
Allow extensions to get their current extension object with:
let extension = imports.misc.extensionUtils.getCurrentExtension();
As such, extensions can now get their own extension object before the
'init' method is called, so they can import submodules or do other things
at the module scope:

const dataPath = GLib.build_filenamev([extension.path, 'awesome-data.json']);
