Title:
Leaks GVariant's in multiple places
Status in libdbusmenu package in Ubuntu:
Fix Released
Status in libdbusmenu source package in Precise:
Fix Released
Status in libdbusmenu source package in Quantal:
Won't Fix
Bug description:
[Impact]
* Affected applications with a high number of menu updates reach the maximum
value allowed for the ID of a menuitem, and rejects further menu changes.
Because the application underneath the menu has already removed the underlying
actual GtkMenuItem objects, it is impossible to activate the items -- to effect
the actions linked to the menuitems.
* Some indicators have a relatively high and climbing memory usage due to
the way they build menus to be displayed in the panel.
[Test Case]
* Run nm-applet for a while (multiple days without shutdown, without killing
the application), notice whether the menus are still usable.
* Run indicators for a while, observe memory usage.
[Regression Potential]
Indicators with a very high amount of updates may be affected as circling
back past the maximum value, if a new menu item is created with an ID still in
use by a menuitem that has not been removed yet, neither or only one of the two
menu items might be available to be clicked -- this could confuse users or
cause error messages to be displayed.
Risk is low however since network-manager-gnome (nm-applet) is currently the
application with the most menu updates.
[Other Info]
Dbusmenu seems to assume in multiple places that g_variant_parse() returns a
floating reference. It doesn't, so these GVariant's are leaked.
It does things like:
g_variant_builder_add_value(&builder, g_variant_parse(....));
GVariant *variant = g_variant_parse(....);
g_variant_ref_sink(variant);
...
g_variant_unref(variant);
Both of these cases result in a leak
