Re: Activating a VPN connection without displaying the authentication dialog

Hello Thomas,

I don't think subclassing NMSecretAgentOld is possible in Python. I am now
trying to use the DBus interface to register my script as a Secret Agent but
my code never gets called. Here's my current script:

    import os
    import sys

    import gi
    gi.require_version('NM', '1.0')
    from gi.repository import Gio, GLib, NM

    base_path = os.path.abspath(os.path.dirname(sys.argv[0]))
    xml_path = os.path.join(
        base_path,
        'org.freedesktop.NetworkManager.SecretAgent.xml')

    xml = open(xml_path, 'r').read()
    node = Gio.DBusNodeInfo.new_for_xml(xml)
    loop = GLib.MainLoop()

    def handle_method_call(
        connection, sender, object_path, interface_name,
        method_name, params, invocation
    ):
        print(f"CALLED: {method_name}({params.unpack()})")
        invocation.return_gerror(GLib.Error())

    def on_bus_acquired(connection, name):
        print("Bus acquired for name, ", name)
        reg_id = connection.register_object(
            "/dev/ileonte/VPNSSO",
            node.interfaces[0],
            handle_method_call,
            None, None
        )
        print(f'reg_id = {reg_id}')

    def on_name_acquired(connection, name):
        print("Name acquired :", name)
        proxy = Gio.DBusProxy.new_for_bus_sync(
            Gio.BusType.SYSTEM,
            Gio.DBusProxyFlags.NONE,
            None,
            "org.freedesktop.NetworkManager",
            "/org/freedesktop/NetworkManager/AgentManager",
            "org.freedesktop.NetworkManager.AgentManager",
            None,
        )
        val = GLib.Variant(
            '(su)',
            (name, NM.SecretAgentCapabilities.VPN_HINTS))
        ret = proxy.call_sync(
            "RegisterWithCapabilities",
            val,
            Gio.DBusCallFlags.NO_AUTO_START,
            -1,
            None)
        print(ret)

    def on_name_lost(connection, name):
        print("Name lost :", name)
        exit(0)


    if __name__ == "__main__":
        owner_id = Gio.bus_own_name(
            Gio.BusType.SESSION,
            "dev.ileonte.VPNSSO",
            Gio.BusNameOwnerFlags.NONE,
            on_bus_acquired,
            on_name_acquired,
            on_name_lost,
        )

        loop.run()
        Gio.bus_unown_name(owner_id)
        print("Exiting...")

I can see my object on the session bus, the call to RegisterWithCapabilities()
seems to succeed however I never get any GetSecret() calls.

What am I doing wrong?
