Hi, I'm implementing a server which creates an ObjectManager using the sd-bus API and there seems to be some differences between how gdbus and sd-bus implements the API.
I implemented a simple ObjectManager at /org/gnome/TestManager which exports objects /org/gnome/TestManager/fooX with interface org.gnome.TestManager.Device. Under sd-bus, if an object is removed, the following signal is generated: signal time=1492642227.714223 sender=:1.104 -> destination=(null destination) serial=90 path=/org/gnome/TestManager; interface=org.freedesktop.DBus.ObjectManager; member=InterfacesRemoved object path "/org/gnome/TestManager/foo0" array [ string "org.freedesktop.DBus.Peer" string "org.freedesktop.DBus.Introspectable" string "org.freedesktop.DBus.Properties" string "org.freedesktop.DBus.ObjectManager" string "org.gnome.TestManager.Device" ] If I implement the same simple server in gdbus, the signal is instead: signal time=1492642227.714223 sender=:1.104 -> destination=(null destination) serial=90 path=/org/gnome/TestManager; interface=org.freedesktop.DBus.ObjectManager; member=InterfacesRemoved object path "/org/gnome/TestManager/foo0" array [ string "org.gnome.TestManager.Device" ] The corresponding signals are also generated when an object is added. Beside simply being different, this difference seems to confuse gdbus. If I create a test client, it will report that any object which is already existing when I start the client has 1 interface and any object which is added/removed subsequently is reported as having 5 interfaces, 4 of which are nameless (this would appear to be one or more gdbus bug(s)). This bug in gdbus also means that it doesn't correctly catch the removal of an object which existed at the time the client was started (because of the interface count mismatch). Anyway, gdbus bugs aside, it seems that the interfaces reported by sd-bus should match what gdbus does? (assuming, of course, that gdbus can be considered the "reference" implementation).
