Ensure that the UI is updated when a connection changes name or id,
even if it was already known by a device.
Also, use less private properties on NMConnection objects, as they
can become stale and cause problems.
https://bugzilla.gnome.org/show_bug.cgi?id=677097
Rather than accessing global.session_type / global.session_mode
all over the place, delegate mode information to a dedicated
sessionMode object. While not very useful for now, we will replace
checks for a particular mode with checks for particular properties
that sessionMode defines based on global.session_mode.

Bluetooth PINs are required to have 6 digits, so enforce that
condition by making the PIN request notification's confirm
button insensitive unless the entered PIN has the correct length.

For most subclasses, this is a direct swap -- a lot of the time, the
constructor was a blank class that override createNotificationIcon,
and called _setSummaryIcon in _init.
https://bugzilla.gnome.org/show_bug.cgi?id=661236
We seem to have a lot of code that does something along the lines of:
if (condition)
actor.show();
else
actor.hide();
ClutterActor already has such a thing for exactly this purpose: the 'visible'
property. Use it instead of the mess above.
https://bugzilla.gnome.org/show_bug.cgi?id=672272
nm_active_connection_get_devices() has a (questionable) special case
for the no devices case (which happens if the DBus object is
destroyed because NM went down): it returns null instead of an empty
array. Handle that instead of crashing.
https://bugzilla.gnome.org/show_bug.cgi?id=673043
gnome-settings-daemon commit 07b1ed63016 removed the custom 'Changed'
DBus signal in favor of the standard 'PropertiesChanged' signal, so
use that instead to update the icon.
https://bugzilla.gnome.org/show_bug.cgi?id=667371
Previously the code in _accessPointAdded was iterating over the
the network list to find a good place, and at that time, added both
the network to the list and the item to the menu. When I refactored
to call queueCreateSection, I forgot to add code to insert the
network in the list.
Add it now, using the new Util.insertSorted function.
https://bugzilla.gnome.org/show_bug.cgi?id=666429
By using Main.queueDeferredWork, we can ensure that most of the
menu contents (in particular, the heaviest parts like the list of
wifi networks) are not updated immediately as we receive signals
from NetworkManager. Instead, the menu is rebuilt some time later,
or as soon as the user opens the menu.
This means that it is no longer needed to optimize for the
access-point-added case, replacing a lot of buggy code with a safer
call to _queueCreateSection, which in turn should ensure that the
more menu, if existing, is always at the end and that at most 5 networks
are visible outside it.
https://bugzilla.gnome.org/show_bug.cgi?id=664124
When wifi or wwan are blocked by hardware killswitch, we should not
allow changing the switch (it won't work anyway), and show
"hardware disabled" instead, similar to what we already do in the
bluetooth menu.
https://bugzilla.gnome.org/show_bug.cgi?id=665194
When placing networks in _createSection, we were taking in
consideration that _activeNetwork is always first, by adding 1,
but then kept this offset also for networks following it (normally,
all of them, since _activeNetwork is also the most recently used),
that instead should not be affected by the movement.
This resulted in the menu showing 4 networks + More... instead of
5.
https://bugzilla.gnome.org/show_bug.cgi?id=664124
The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().
https://bugzilla.gnome.org/show_bug.cgi?id=664436
All classes that have at least one other derived class (and thus
benefit from the framework) have been now ported. These includes
NMDevice, SearchProvider, AltTab.SwitcherList, and some other
stuff around.
https://bugzilla.gnome.org/show_bug.cgi?id=664436
Third step in the class framework port, now it's the turn of
MessageTray.Source and MessageTray.Notification, as well as
the various implementations around the shell.
https://bugzilla.gnome.org/show_bug.cgi?id=664436
The Lang module in gjs has recently gained a small yet powerful
Class framework, that should help improve the readability of code
when using complex inheritance.
This commit starts porting shell code, by rewriting all classes in
popupMenu.js (and all derived classes) to Lang.Class.
https://bugzilla.gnome.org/show_bug.cgi?id=664436
The option was merge with 'visual-bell-type' with the GSettings
port, but the change turned out too disruptive for the universal
access menu / settings panel, so gsettings-desktop-schemas commit
a5819b2a4e9 re-added the separate option.
This continues the series of patches for GDBus porting, affecting
all code that accesses remote DBus objects. This includes modemManager,
automount, autorun (for the hotplug sniffer), calendar, network (for
nm-applet only), power, scripting (for perf monitor interface)
https://bugzilla.gnome.org/show_bug.cgi?id=648651
When changing _findNetwork with _findExistingNetwork, I changed
the return value to avoid searching twice for the access point,
and changed some names. I forgot to update all points where those
names were used.
https://bugzilla.gnome.org/show_bug.cgi?id=663278
Previously, we connected to notify::strength only if there was
already a signal connected, and the AP changed (thus, by induction,
we never connected). As a result, the icon became stale and different
from that shown inside the menu (which is correctly updated).
https://bugzilla.gnome.org/show_bug.cgi?id=650007
PopupMenu.firstMenuItem returns a PopupMenuItem, not an apObj. We
need to retrive the latter using the _apObj property.
Also, somehow the property from the number of elements in a menu
was changed from .length to .numMenuItems, and this broke the
destruction of the menu upon emptying it.
https://bugzilla.gnome.org/show_bug.cgi?id=659277
Calling nm_access_point_get_ssid() in the handler of the
access-point-removed signal can result in DBus request, which will
then fail because the object was already removed at the server side.
Instead, use a difference function to retrieve the access point
object (the network), that compares directly by object identity.
https://bugzilla.gnome.org/show_bug.cgi?id=651378
js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.
https://bugzilla.gnome.org/show_bug.cgi?id=660358
Devices are represented as susdut, not susbut (i.e. the percentage
is a double rather than a boolean) - apparently the wrong signature
works, but correct it anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=660122
When the active AP disappears, it is possible to receive the
"access-point-removed" signal before the "notify::active-ap" (as
dbus-glib + libnm-glib property notifications are not reliable).
In that case, we would remove the AP from the network object, thus
an attempt to update the UI would create an item for an empty
network.
https://bugzilla.gnome.org/show_bug.cgi?id=658150
Current code is sometime attempting to create menu items for wifi
networks that have no visible AP. I have no idea why this is
happening, but it should fix the symptoms and avoid exceptions.
https://bugzilla.gnome.org/show_bug.cgi?id=658150
The keyboard status item doesn't derive from SystemStatusButton, since
it doesn't use an icon. But this meant it wasn't getting the right
class name, and so was using the full-width menu title highlight
rather than the small one. Fix that.
It does not make a great amount of sense to have this function
on the login screen. And worse, it does not work, since the greeter
is currently a modal dialog, so interaction with the opening
window is impossible.
https://bugzilla.gnome.org/show_bug.cgi?id=659164
All the system status menus in the panel offer a
menu item to jump to a relevant part of the
control-center.
This means each status icon has the same, or nearly the
same bit of code to:
- Add a new "action" menu item and listen for its activation.
- Hide the overview if it's showing when the menu item is activated
- Find the relevant control-center panel from its desktop file
- Launch the control-center to the relevant panel
This commit consolidates all those details in a new method,
addSettingsAction. This refactoring reduces code duplication and
slight inconsistencies in the code resulting from that duplication.
It will also make it easier in subsequent commits to hide settings menu
items when the shell is used in the login screen.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
A separator only makes sense if there are items on both
sides of it. There is quite a lot of code written
throughout the shell that manages the process of showing
and hiding separators as the items around those separators
change.
This commit drops all that code in favor of changes to the menu
implementation to dynamically hide or show separators as
appropriate, so the callers don't have to deal with it.
https://bugzilla.gnome.org/show_bug.cgi?id=657082
Wireless and 3g dialog code has moved to gnome-control-center, so
we can stop calling out to nm-applet. Also, we can now enable the
notifications provided by the shell and kill a bit of code about
auth that is not actually needed.
https://bugzilla.gnome.org/show_bug.cgi?id=650244
It is not possible to connect to hidden access points without
knowing the SSID, and it should be done using the control center
panel and the appropriate dialog. At the same time, this should
fix some warnings from libnm-glib and dbus-glib.
https://bugzilla.gnome.org/show_bug.cgi?id=646454
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.
https://bugzilla.gnome.org/show_bug.cgi?id=648149
Since this link in the keyboard menu points to Region and Language
Settings in System Settings, we should be consistent and use that
term instead of "Localization Settings"
Also, this removes ellipsis from "Show Keyboard Layout" since it
doesn't require further input.
https://bugzilla.gnome.org/show_bug.cgi?id=652984
Keeping the volume menu open after setting the desired volume isn't that
useful and forces a second click (or an Esc press) to dismiss it. Allow for
the sliders to be used with a single click-hold-move-release.

On error, we tried to kill and respawn gnome-power-manager, but
as of commit c5676900 the DBus interface provided by g-s-d's power

When one of the networks in the main menu is removed and we have
a More... submenu, we can take the first out from the submenu and

Use the new PopupSwitchMenuItem functionality when bluetooth cannot
be enabled. Use it also for showing "connecting..." when activating
device items.
https://bugzilla.gnome.org/show_bug.cgi?id=648048
Moves and converts NMDeviceTitleMenuItem from network.js into
PopupSwitchMenuItem, so that it can show both a switch and a
greyed-out status label. This will be soon used by the Bluetooth menu.
https://bugzilla.gnome.org/show_bug.cgi?id=648048
_createNetworkItem was always appending access point at the end of
the menu when their position was < 5 (NUM_VISIBLE_NETWORKS), ignoring
the presence or absence of _overflowItem, which thus ended in the
middle of the network list. Fix that.
https://bugzilla.gnome.org/show_bug.cgi?id=652313
If we have more than 5 (which can happen with VPN connections), place
them into a More... submenu, which also becomes scrollable if needed.
To protect from race conditions and ordering issues while reading
connections, sort them in alphabetic order when the timestamp is equal.
https://bugzilla.gnome.org/show_bug.cgi?id=651602
Some users are confused when their devices are not shown in the
network menu, even if they configured them manually. Mark their presence
by showing them in the menu, even if they cannot be otherwise
interacted with.
Also add a status string for deactivating devices (none currently,
soon will appear in NetworkManager).
https://bugzilla.gnome.org/show_bug.cgi?id=646946
All WPA APs were getting set as WPA2 due to the check for privacy;
WPA/WPA2 APs *must* set the Privacy bit according to the standard,
so we'd never end up in the case for NMAccessPointSecurity.WPA.
Fix that, and also add flags for WPA[2] Enterprise which we'll
use a bit later for the first-time connect case for 802.1x enabled
access points.
Instead of rolling our own code, use new libnm-glib functions to do
the same thing. Requires libnm-glib as of
779215c742bbe29a2c66202ec7e2e6d43edeb8ff (which will be part of 0.9).
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=648648
Previously, we skipped rebuilding device items in case the device
had already been seen, but this caused the connected switch not to
be updated. Now it has been refactored to update in case the device
changes, and to create only when the device is completely new.
https://bugzilla.gnome.org/show_bug.cgi?id=647565
Adds a function that compares wireless networks and keeps them sorted
at all times. Order is: first already configured connections, then
first secure networks, then alphabtic. Also, the appearance of a new access
point no longer causes the whole menu to be rebuilt (but it still linear
searches for the position, I guess that could be skipped), which caused
the addition of more code for tracking the active access point.
https://bugzilla.gnome.org/show_bug.cgi?id=646580
The IP_CHECK and SECONDARIES states should be considered part of the
"connecting..." phase.
DEACTIVATING should be its own stage, but that would break string
freeze, so we just treat it like DISCONNECTED for now.
UNMANAGED needs to be treated differently in 3.2, but it is too late
to fix it for 3.0.1.
https://bugzilla.gnome.org/show_bug.cgi?id=646946
When more than one device exists, we need to reset the section title's
device to null, and in that case we must show nothing (neither the switch
nor the label, but an empty label is OK anyway). Also, we need to
update the device statusItem immediately when constructing it, as we
may not get any state-changed.
https://bugzilla.gnome.org/show_bug.cgi?id=646074
NMDeviceModem._createSection was not checking whether it should have
shown the connection list, resulting in status item shown even if
the device was in an invalid state.
Also, fix a logic error when creating the operatorItem and fix overriding
_clearSection protected method.
https://bugzilla.gnome.org/show_bug.cgi?id=646395
NMApplet connects to each NMDevice's state-changed signal and stores
the signal handler id on the NMDevice itself. However, it was using
the same name as NMDevice itself was using to store the handler ID for
the underlying GObject's state-changed signal, thus overwriting it,
and resulting in *neither* signal handler getting removed if the
device went away. (This probably isn't a problem, since the device is
going away, but it causes a warning.)
Also, at least for WWAN devices, the device state changes to UNMANAGED
immediately before disappearing, but getStatusLabel() wasn't handling
that case and printed a warning instead. Fix that.
https://bugzilla.gnome.org/show_bug.cgi?id=646708
If you restart NetworkManager, then the list of active connections
is emptied, then comes back with the same GObjects in it. If the
_primaryDevice field isn't cleared on the object, then we won't
know we need to set it back on the device, resulting in the active
device not showing up in the menu.
https://bugzilla.gnome.org/show_bug.cgi?id=646558
A notify signal does not include the new value of the property in
its signature, so the handler was trying to compare a GParamSpec with
a number when updating. Fix it to always retrieve the value from the
object.
https://bugzilla.gnome.org/show_bug.cgi?id=646443
Since the icon area is end-aligned, the signal strength icon for
insecure networks was ending up aligned with the lock icon for secure
networks. Fix that by always including a _secureIcon, but having it be
blank for the insecure networks.
https://bugzilla.gnome.org/show_bug.cgi?id=646121
Some connection types (like wimax) are not supported by the menu, and
should be ignored instead of throwing exceptions. Also, NetworkManager
had a bug that sent connections with invalid settings. This should not
happen, but in case it does, we will not blow up, but just log a warning
and continue silently.
https://bugzilla.gnome.org/show_bug.cgi?id=646355
When a device is connecting, we can continue showing available
connections and access points, as well as the active one with the dot.

A cosmetic change recommended in review of the patch to fix the
VPN Connections switch ended up introducing a logic error that
made the switch not work properly. Fix.
https://bugzilla.gnome.org/show_bug.cgi?id=646380
It was always reporting true, even if disconnected. At the same time,
add a signal that is emitted when state changes and update the UI
accordingly.
In the future (with another libnm-glib API break) we should use the
NMVPNConnection object to track the connection state, so that we can
show if we're connecting or we need authentication.
https://bugzilla.gnome.org/show_bug.cgi?id=646380
NMDevice._findConnection expects an uuid as parameter, but
checkConnection was passing a NMConnection object. This caused
exists to be always false, thus the connection was added again every
time the 'updated' signal was emitted.
https://bugzilla.gnome.org/show_bug.cgi?id=645702
For wired devices (actually, ethernet devices), hide the connection
list when there is only one connection (either automatic or stored).
The device can be operated with the associated switch.
Since device state Unavailable is generic and has substates, instead
of using an hack for carrier, introduce some code that checks both
for carrier and firmware-missing when in that device state, and updates
the UI accordingly.
Different methos are being used to launch the control-center panels of each
status icon. Standarize on Shell.AppSystem.
This also fixes the network icon using a non-existant Util.spawnDesktop()
method.
Bug #645091
In commit 9bd22dc0, I introduced an API to load an arbitrary
.desktop file, not necessarily from the menu path. It turns
out this function was broken because it created ShellApp instances
that were *different* from ones that were cached normally.
As far as I can tell, we didn't initially use it. Then later
Util.spawnDesktop was created which used this function.
Remove this broken function and all callers; if we're loading
.desktop files from *outside* the menu path, we can look at
readding.
This patch also kills off Util.spawnDesktop in favor of callers
talking to ShellAppSystem directly, now that the latter reports
errors.
