Signals, some are dropped?

Hi All,

Recently I have written some code that processes signals using the
lowlevel dbus api. The odd part is that my code does not seem to be
receiving all the signals sent to it. I can use dbus-send to send the
same signal and sometimes my code gets it and sometimes it doesn't. It
is not even one of those cases where it gets 2 and then misses one and
then gets 2 and misses 1.

I have a match setup and it calls my signal handler which all it does is
print the signal info and then exit. I can sent the signal say 5 times
and the handler will be called only 3 of those times. Is there anything
I can do to improve this..

handler

static DBusHandlerResult filter_func(DBusConnection * connection,
                                     DBusMessage * message, void *user_data)
{

    const char *sender;
    const char *destination;
    int message_type;
    char *s = NULL;
	DBusError error;
	
    message_type = dbus_message_get_type(message);
    sender = dbus_message_get_sender(message);
    destination = dbus_message_get_destination(message);
	
    if (message_type == DBUS_MESSAGE_TYPE_SIGNAL) {
        printf("path=%s; interface=%s; member=%s; data=%s\n",
               dbus_message_get_path(message),
               dbus_message_get_interface(message), 		
dbus_message_get_member(message), s);

    }
    return DBUS_HANDLER_RESULT_NOT_YET_HANDLED;
}


how I hook it from a gtk app. I tried dbus-glib but didn't have much
luck with it.


gboolean dbus_hookup(gint windowid)
{

    DBusConnection *connection;
    DBusError error;
    DBusBusType type = DBUS_BUS_SESSION;
    gchar *match;

    dbus_error_init(&error);
    connection = dbus_bus_get(type, &error);
    if (connection == NULL) {
        printf("Failed to open connection to %s message bus: %s\n",
               (type == DBUS_BUS_SYSTEM) ? "system" : "session",
error.message);
        dbus_error_free(&error);
        return FALSE;
    }
    dbus_connection_setup_with_g_main(connection, NULL);

	match = g_strdup_printf("type='signal',interface='com.my.interface'");
	dbus_bus_add_match(connection, match, &error);	
    printf("Using match: %s\n", match);
    g_free(match);
	
	
    if (!dbus_connection_add_filter(connection, filter_func, NULL, NULL)) {
        printf("Couldn't add filter!\n");
        return FALSE;
    }

    printf("Proxy connections and Command connected\n");

    return TRUE;
}


I'm using dbus 1.0.1-9 as packaged by Fedora Core 6.

Thanks,

Kevin
