question about empty reply of talking to nm-system-settings via dbus

[cee1]

Hi Dan,

I've compiled and installed nm-0.7.1-rc3 manually in debian, then try the following:

dbus-send --system --print-reply --dest=org.freedesktop.NetworkManagerSystemSettings /org/freedesktop/NetworkManagerSettings org.freedesktop.DBus.Properties.GetAll string:org.freedesktop.NetworkManagerSettings.System

It prints:

nm-system-settings: introspection data references non-existing property Hostname

nm-system-settings: introspection data references non-existing property CanModify

nm-system-settings: introspection data references non-existing property UnmanagedDevices

method return sender=:1.12 -> dest=:1.15 reply_serial=2

    array [

    ]

No hostname is returned, the version of dbus is 1.2.1

Any suggestions?

Thanks

- cee1

Interesting; what version of dbus-glib?  Earlier versions had problems
with GetAll specifically.  You may need these dbus-glib commits:

http://cgit.freedesktop.org/dbus/dbus-glib/commit/?id=94d68f00d9d244de3b1d66d3cf78bb5171552311
http://cgit.freedesktop.org/dbus/dbus-glib/commit/?id=d1b80d803a0268bd4b3dd5b9a9522230461f2947

Does it work if you get each property individually?  That would point
directly to a dbus-glib issue.

dbus-send --system --print-reply \
        --dest=org.freedesktop.NetworkManagerSystemSettings \
        /org/freedesktop/NetworkManagerSettings \
        org.freedesktop.DBus.Properties.Get \
        string:org.freedesktop.NetworkManagerSettings.System \
        string:Hostname
