While can_open_new_window() uses some elaborate heuristics to predict
whether an application can open multiple windows, open_new_window()
will always simply relaunch the application. This is often the best
we can do, but when an application provides a "new-window" action in
its .desktop file or on the bus, it is much more likely to work as
expected than blindly activating the app and hoping for a particular
behavior.

Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.
https://bugzilla.gnome.org/show_bug.cgi?id=759538
Similar to what it's done in _shell_app_add_window(), rely on calling
shell_app_sync_running_state() when removing windows too, to avoid
transitioning to STOPPED while it's still in the STARTING state.
This makes the logic compliant with the startup notification spec and
prevents stopping an application too early if it has a splash screen
that has been closed before the application's main window is shown.
https://bugzilla.gnome.org/show_bug.cgi?id=787905
And adapt existing callers to the new API. This will allow us to
implement a way to launch applications on the discrete GPU for systems
where an "Optimus" system exists.

We used to take window visibility into account when comparing apps
until commit 1dfc38d078, following changes in the window switcher
due to auto-minimization. However auto-minimization was abolished
and the window switcher changes reverted, so it makes sense again
to sort apps without non-minimized windows last again.
https://bugzilla.gnome.org/show_bug.cgi?id=766238
The JS code could still be holding on to a reference to a window-backed app
after all windows have vanished. (For example, the dash queues an idle to
refetch apps and display them.) Avoid dying with an error message if we
attempt to activate or otherwise manipulate such a window.
https://bugzilla.gnome.org/show_bug.cgi?id=674799
When the last interesting window of an app-backed window is removed,
we'll transition it back to STOPPED, but we transition the state and
send out the signal before we clear the running state.
This means that any listeners to the state-changed signal might
encounter a window-backed app that has a running state, but no
windows. If they call, e.g. shell_app_get_name, while in this state,
they'll encounter an assertion fail.
Apps that are starting might have uninteresting windows like splash
screens pop up and then go away (like LibreOffice), even when
startup-notification hasn't completed yet. In those cases, we don't
want to transition the app back to stopped -- it should remain in
the running state.
Themes - namely the HighContrast one - may now request symbolic
icons rather than fullcolor ones. In order to have recoloring
work as expected in that case, we will need a theme node to pick
up colors from - using an StIcon instead of manually loading a
texture from the cache gives us that for free, so do that.
https://bugzilla.gnome.org/show_bug.cgi?id=740447
Using a separate property to show when the application is busy rather
than cramming it into the state property makes the code clearer. In most
places we only care if an app is running or not, not whether it is
actually busy.
https://bugzilla.gnome.org/show_bug.cgi?id=736492
This simplifies the code and fixes a race where an application could
call g_application_mark_busy() before the shell subscribed to change
notifications on the application's busy state.
https://bugzilla.gnome.org/show_bug.cgi?id=736492
If the application reports itself as single window (through
an explicit indication in the desktop file or some heuristics),
not show a "New window" item that doesn't actually open a new window.
https://bugzilla.gnome.org/show_bug.cgi?id=722554
So far we have assumed that whether or not a window is interesting
is static. In general this is the case, but as it is legal for the
underlying properties to change at any time, there are of course
offenders that actually do this (flash I'm looking at ya).
While we used the property to determine whether a window should be
tracked or not, the worst case was showing windows that should be
hidden or missing windows that should be shown.
However as we nowadays base an app's running state on the number of
interesting windows, we need to be more careful in order to avoid
ending up with running apps with no windows.
https://bugzilla.gnome.org/show_bug.cgi?id=723308
With the lastest ShellApp changes, an app is considered stopped
when the last "interesting" window is closed. However the app
may still track non-interesting windows, so if we unref the
running state on the state transition, we hit an assertion later-on
when trying to remove the non-interesting window.
Fix this by keeping the running state around until the last window
is closed.
https://bugzilla.gnome.org/show_bug.cgi?id=722840
An app should be considered running if it has at least one "interesting"
window, however the code considers an app running if it has at least
one tracked window. This was fine while we were only tracking interesting
windows, but since commit d21aa0d85f this is no longer the case.
So keep track of the number of interesting windows as well and use that
to determine the running state.
https://bugzilla.gnome.org/show_bug.cgi?id=722690
Using the new list_actions() API in Gio, add entries for static
actions specified in .desktop files in the right-click app menus,
in the dash, app well and search.
https://bugzilla.gnome.org/show_bug.cgi?id=669603
Filtering out "non-interesting" windows beforehand as we currently do
means that we may get properties that should be based on all windows,
like the last time the application was used, wrong.
Just track all windows and filter out non-interesting windows manually
in the one place we actually care about the difference.
https://bugzilla.gnome.org/show_bug.cgi?id=719824
Rather than scanning all apps for searching, use Ryan's new desktop
file index and the glib support APIs for app searching instead of our

Systemd-for-the-user-session would also do this, but that's a deeply
invasive change that I may not actually get to this cycle. This
change is tiny and non-invasive, but provides an important benefit:
You can actually reliably tell *which* applications are logging which
messages (assuming they're launched by the shell).
This actually complements a recent change in DBus:
See https://bugs.freedesktop.org/show_bug.cgi?id=68559
which does a similar thing for bus activated apps.
https://bugzilla.gnome.org/show_bug.cgi?id=711626
shell_app_compare() (which is only used as sort function for
shell_app_system_get_running() nowadays) currently takes the
visibility of an app's windows into account, e.g. applications
with visible windows (non-minimized windows on current workspace)
sort earlier than applications without.
This translate traditional window-switcher behavior to applications,
but we stopped sorting by workspace in the app-switcher a while ago,
and with the new auto-minimization behavior of fullscreen windows
it is more confusing than helpful - in fact, since mutter commit
7e61ef09369a we no longer do this for the window list, so it
makes sense to apply the same to application sorting.
https://bugzilla.gnome.org/show_bug.cgi?id=707663
The point of fading the icon is to make the text displayed over the
icon more legible. In RTL layouts, the text is displayed on the left
of the icon, so fading the right-hand-side of the icon doesn't work
well.

This includes a rename from the G* namespace to the Gtk* one, which
will help us with introspecting this code. Note that this removes
some of the custom code we added to GActionMuxer to relay event times
to the remote action group. We'll add this back soon.
https://bugzilla.gnome.org/show_bug.cgi?id=700257
Currently we assume that GTK_UNIQUE_BUS_NAME is shared between all
windows of an application. This assumption does not hold true for
applications that specify G_APPLICATION_NON_UNIQUE, so make sure
to update the menu as necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=676238
ShellApp keeps track of windows sorted by most recently used first
which means that when raising windows we need to start from the end of
the list to finish with the correct stacking order.
This patch just makes the code agree with the comment which was
already there.
https://bugzilla.gnome.org/show_bug.cgi?id=676371
.desktop files have been designed for browsing, so the existing
fields often produce insufficient results when used for search.
gnome-control-center used X-GNOME-Keywords for that purpose, which
has now been standardized as Keywords. It makes sense for us to
support it in gnome-shell as well (and encourage its use outside
of settings panels).
https://bugzilla.gnome.org/show_bug.cgi?id=609702
The application proxy is created asynchrously after the dbus name
is registed. This means that when tracking the first window (and
therefore creating the first window GActionGroup) there is no
app proxy yet.
https://bugzilla.gnome.org/show_bug.cgi?id=633028
It's not guaranteed that the application DBus proxy appears before
we receive the first focus event from the toplevel window.
Ensure that the first method to access the action muxer creates it if
hasn't been created yet.
GTK+ also exports window-specific actions, by putting the object path
for the exported action group in the _DBUS_OBJECT_PATH X property.
We add this action group to the app's muxer with a 'win' prefix,
since that is what the exported menu expects. Whenever the focus
window changes, we update the window-specific actions of its
application, and emit notify::action-group to cause the app
menu to be updated.
GDBusActionGroup api has changed again, adapt to that.
Also, use a GActionMuxer to add the 'app.' prefix to actions,
instead of manually stripping it out of the action names.
In the future, the muxer will also contain per-window actions
with a 'win.' prefix.
GMenuProxy has been replaced by GDBusMenuModel, and the object path
has been moved (now needs to be retrieved from the AppMenu GApplication
property).
Update the test to prefix each action with "app." as documented,
and use a GtkApplicationWindow instead of a plain GtkWindow.
GDBusActionGroup and GMenuProxy are new objects in GIO 2.32 that
help with accessing menus and actions of remote applications.
This patch makes it possible for the shell to associate an
application with a dbus name and from that a GMenu, that will
be shown as the application menu.

Not all desktop files tracked by the shell have
Exec lines. This could be because they're actually
run by another process, for instance, and the desktop
file is merely there to provide metadata. For example,
nautilus-pastebin provides a desktop file without an
Exec line.
The shell currently crashes if one of these partial
desktop files is installed and the user attempts to
search from the overview.
commit 37726a4cb6 fixed
a similar crasher.
This commit fixes the next one lower in the code.

Instead of saving the last_used_time per-app, grab the maximum time for all
windows. The logic is less hard to keep track of, and it solves some edge
case issues where windows that no longer exist update the user time, even
if none of the other windows have been used recently.
https://bugzilla.gnome.org/show_bug.cgi?id=660650
We originally OR'ed search terms and favored results which matched
multiple times to get more relevant results. When changing search
to AND search terms, the semantics of "multiple matches" were
changed to refer to a single term matching multiple criteria (name,
executable), which seemed like a good idea at the time.
However in practice this just results in applications whose
user-visible name matches the executable name on disk being
favored over applications using a more generic name, which
isn't too useful (in particular when taking usage frequency
into account).
https://bugzilla.gnome.org/show_bug.cgi?id=623372
Currently we use a very strict definition of "prefix", where the
search term has to match at the very beginning of the searched
criteria (application name, executable name). Use a more liberal
definition by including matches where the preceding character is
a space (application name) or hyphen (executable name) as well;
as many applications use a prefix, this should improve the quality
of results.
https://bugzilla.gnome.org/show_bug.cgi?id=623372
Commit 0af108211c introduced a
regression where applications that appear in multiple categories were
duplicated in the "All Apps" list, because we switched from
uniquifying on desktop file ID to the GMenuTreeEntry.
Switch back to keeping the set of apps based on ID. To flesh this
out, we keep the ShellApp instance for a given ID around forever, and
when we're loading new contents, we replace the GMenuTreeEntry inside
the app. That means callers still get new data.
We still keep around the running app list, though we could just
recompute it from the app list now.
https://bugzilla.gnome.org/show_bug.cgi?id=659351
This patch fixes the "apps vanish from alt-TAB bug".
If a "package system" rips away and possibly replaces .desktop files
at some random time, we have historically used inotify to detect this
and reread state (in a racy way, but...). In GNOME 2, this was
generally not too problematic because the menu widget was totally
separate from the list of windows - and the data they operate on was
disjoint as well.
In GNOME 3 we unify these, and this creates architectural problems
because the windows are tied to the app.
What this patch tries to do is, when rereading the application state,
if we have a running application, we keep that app around instead of
making a new instance. This ensures we preserve any state such as the
set of open windows.
This requires moving the running state into ShellAppSystem. Adjust
callers as necessary, and while we're at it drop the unused "contexts"
stuff.
This is just a somewhat quick band-aid; a REAL fix would require us
having low-level control over application installation. As long as
we're on top of random broken tar+wget wrappers, it will be gross.
A slight future improvement to this patch would add an explicit
"merge" between the old and new data. I think probably we always keep
around the ShellApp corresponding to a given ID, but replace its
GMenuTreeEntry.

During a state transition from running to not-running for

As danw points out,
"It's unique during the lifetime of the window, but reasonably likely to be
reused by another window after this one is destroyed. Using

Since almost all of the callers of shell_app_activate were using the
default workspace (by passing -1), remove that parameter.
Add a new shell_app_activate_full() API which takes a workspace as
well as a timestamp; previously we might have been ignoring event
timestamps from elsewhere.
https://bugzilla.gnome.org/show_bug.cgi?id=648149
This dramatically thins down and sanitizes the application code.
The ShellAppSystem changes in a number of ways:
* Preferences are special cased more explicitly; they aren't apps,
they're shortcuts for an app), and we don't have many of them, so
don't need e.g. the optimizations in ShellAppSystem for searching.
* get_app() changes to lookup_app() and returns null if an app isn't
found. The semantics where it tried to find the .desktop file
if we didn't know about it were just broken; I am pretty sure no
caller needs this, and if they do we'll fix them.
* ShellAppSystem maintains two indexes on apps (by desktop file id
and by GMenuTreeEntry), but is no longer in the business of
dealing with GMenuTree as far as hierarchy and categories go. That
is moved up into js/ui/appDisplay.js. Actually, it flattens both
apps and settings.
Also, ShellWindowTracker is now the sole reference-owner for
window-backed apps. We still do the weird "window:0x1234beef" id
for these apps, but a reference is not stored in ShellAppSystem.
The js/ui/appDisplay.js code is rewritten, and sucks a lot less.
Variable names are clearer:
_apps -> _appIcons
_filterApp -> _visibleApps
_filters -> _categoryBox
Similarly for function names. We no longer call (for every app) a
recursive lookup in GMenuTree to see if it's in a particular section
on every category switch; it's all cached.
NOTE - this intentionally reverts the incremental loading code from
commit 7813c5b93f. It's fast enough
here without that.
