Hi all,
At the moment after connecting an app, mesh daemon only watches for
that app disconnecting from D-Bus with:
node->disc_watch = l_dbus_add_disconnect_watch(bus,
node->owner, app_disc_cb, node, NULL);
in node.c::get_managed_objects_cb
I can unregister all of the app interfaces (leaving it non functional
but still connected to D-Bus) and mesh daemon will not be aware of
that, still trying to communicate with it.
This is especially problematic if app stops functioning correctly, but
daemon continues to call its methods i.e. when a message is received.
Maybe it would be beneficial for mesh daemon to listen to
InterfacesRemoved signals to determine when apps/nodes disconnect:
signal time=1564398245.483028 sender=:1.6219 -> destination=(null
destination) serial=27 path=/com/silvair/application;
interface=org.freedesktop.DBus.ObjectManager; member=InterfacesRemoved
object path "/com/silvair/application"
array [
string "org.mesh daemon.mesh.Application1"
string "org.mesh daemon.mesh.ProvisionAgent1"
]
signal time=1564398245.483133 sender=:1.6219 -> destination=(null
destination) serial=28 path=/com/silvair/application/element0;
interface=org.freedesktop.DBus.ObjectManager; member=InterfacesRemoved
object path "/com/silvair/application/element0"
array [
string "org.mesh daemon.mesh.Element1"
]
This would give applications ability to, for example, have a multiple
nodes registered and remove/change some of them without whole app
restarting.
Best Regards
