32 * @title: GDBusMenuModel
33 * @short_description: A D-Bus GMenuModel implementation
34 * @see_also: <link linkend="gio-GMenuModel-exporter">GMenuModel Exporter</link>
36 * #GDBusMenuModel is an implementation of #GMenuModel that can be used
37 * as a proxy for a menu model that is exported over D-Bus with
38 * g_dbus_connection_export_menu_model().
42 * There are 3 main (quasi-)classes involved here:
48 * Each of these classes exists as a parameterised singleton keyed to a
51 * - GDBusMenuPath represents a D-Bus object path on a particular
52 * unique bus name on a particular GDBusConnection and in a
53 * particular GMainContext.
55 * - GDBusMenuGroup represents a particular group on a particular
58 * - GDBusMenuModel represents a particular menu within a particular
61 * There are also two (and a half) utility structs:
63 * - PathIdentifier and ConstPathIdentifier
64 * - GDBusMenuModelItem
66 * PathIdentifier is the 4-tuple of (GMainContext, GDBusConnection,
67 * unique name, object path) that uniquely identifies a particular
68 * GDBusMenuPath. It holds ownership on each of these things, so we
69 * have a ConstPathIdentifier variant that does not.
71 * We have a 3-level hierarchy of hashtables:
73 * - a global hashtable (g_dbus_menu_paths) maps from PathIdentifier
76 * - each GDBusMenuPath has a hashtable mapping from guint (group
77 * number) to GDBusMenuGroup
79 * - each GDBusMenuGroup has a hashtable mapping from guint (menu
80 * number) to GDBusMenuModel.
82 * In this way, each quintuplet of (connection, bus name, object path,
83 * group id, menu id) maps to a single GDBusMenuModel instance that can be
84 * located via 3 hashtable lookups.
86 * All of the 3 classes are refcounted (GDBusMenuPath and
87 * GDBusMenuGroup manually, and GDBusMenuModel by virtue of being a
88 * GObject). The hashtables do not hold references -- rather, when the
89 * last reference is dropped, the object is removed from the hashtable.
91 * The hard references go in the other direction: GDBusMenuModel is created
92 * as the user requests it and only exists as long as the user holds a
93 * reference on it. GDBusMenuModel holds a reference on the GDBusMenuGroup
94 * from which it came. GDBusMenuGroup holds a reference on
97 * In addition to refcounts, each object has an 'active' variable (ints
98 * for GDBusMenuPath and GDBusMenuGroup, boolean for GDBusMenuModel).
100 * - GDBusMenuModel is inactive when created and becomes active only when
101 * first queried for information. This prevents extra work from
102 * happening just by someone acquiring a GDBusMenuModel (and not
103 * actually trying to display it yet).
105 * - The active count on GDBusMenuGroup is equal to the number of
106 * GDBusMenuModel instances in that group that are active. When the
107 * active count transitions from 0 to 1, the group calls the 'Start'
108 * method on the service to begin monitoring that group. When it
109 * drops from 1 to 0, the group calls the 'End' method to stop
112 * - The active count on GDBusMenuPath is equal to the number of
113 * GDBusMenuGroup instances on that path with a non-zero active
114 * count. When the active count transitions from 0 to 1, the path
115 * sets up a signal subscription to monitor any changes. The signal
116 * subscription is taken down when the active count transitions from
119 * When active, GDBusMenuPath gets incoming signals when changes occur.
120 * If the change signal mentions a group for which we currently have an
121 * active GDBusMenuGroup, the change signal is passed along to that
122 * group. If the group is inactive, the change signal is ignored.
124 * Most of the "work" occurs in GDBusMenuGroup. In addition to the
125 * hashtable of GDBusMenuModel instances, it keeps a hashtable of the actual
126 * menu contents, each encoded as GSequence of GDBusMenuModelItem. It
127 * initially populates this table with the results of the "Start" method
128 * call and then updates it according to incoming change signals. If
129 * the change signal mentions a menu for which we current have an active
130 * GDBusMenuModel, the change signal is passed along to that model. If the
131 * model is inactive, the change signal is ignored.
133 * GDBusMenuModelItem is just a pair of hashtables, one for the attributes
134 * and one for the links of the item. Both map strings to GVariant
135 * instances. In the case of links, the GVariant has type '(uu)' and is
136 * turned into a GDBusMenuModel at the point that the user pulls it through
139 * Following the "empty is the same as non-existent" rule, the hashtable
140 * of GSequence of GDBusMenuModelItem holds NULL for empty menus.
142 * GDBusMenuModel contains very little functionality of its own. It holds a
143 * (weak) reference to the GSequence of GDBusMenuModelItem contained in the
144 * GDBusMenuGroup. It uses this GSequence to implement the GMenuModel
145 * interface. It also emits the "items-changed" signal if it is active
146 * and it was told that the contents of the GSequence changed.

431 * OFFLINE: not subscribed to this group
432 * PENDING: we made the call to subscribe to this group, but the result
433 * has not come back yet
434 * ONLINE: we are fully subscribed
436 * We can get into some nasty situations where we make a call due to an
437 * activation request but receive a deactivation request before the call
438 * returns. If another activation request occurs then we could risk
439 * sending a Start request even though one is already in progress. For
440 * this reason, we have to carefully consider what to do in each of the
441 * three states for each of the following situations:
443 * - activation requested
444 * - deactivation requested
445 * - Start call finishes
447 * To simplify things a bit, we do not have a callback for the Stop
448 * call. We just send it and assume that it takes effect immediately.
450 * Activation requested:
451 * OFFLINE: make the Start call and transition to PENDING
452 * PENDING: do nothing -- call is already in progress.
453 * ONLINE: this should not be possible
455 * Deactivation requested:
456 * OFFLINE: this should not be possible
457 * PENDING: do nothing -- handle it when the Start call finishes
458 * ONLINE: send the Stop call and move to OFFLINE immediately
460 * Start call finishes:
461 * OFFLINE: this should not be possible
463 * If we should be active (ie: active count > 0): move to ONLINE
464 * If not: send Stop call and move to OFFLINE immediately
465 * ONLINE: this should not be possible
467 * We have to take care with regards to signal subscriptions (ie:
468 * activation of the GDBusMenuPath). The signal subscription is always
469 * established when transitioning from OFFLINE to PENDING and taken down
470 * when transitioning to OFFLINE (from either PENDING or ONLINE).
472 * Since there are two places where we transition to OFFLINE, we split
473 * that code out into a separate function.
