[libvirt] [libvirt-glib 19/20] gconfig: Add precondition to gvir_config_object_get_xml_node()

This will catch (among other things) cases when gvir_config_object_get_xml_node() is called with a NULL argument. Not catching this could cause a crash later on in cases when gvir_config_object_new_from_xml() is called and returns NULL, and then we call gvir_config_object_get_attribute() on it. Now this should be caught with runtime warnings so that the underlying issue can be fixed. --- libvirt-gconfig/libvirt-gconfig-object.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/libvirt-gconfig/libvirt-gconfig-object.c b/libvirt-gconfig/libvirt-gconfig-object.c index 6225de2..8cc4065 100644 --- a/libvirt-gconfig/libvirt-gconfig-object.c +++ b/libvirt-gconfig/libvirt-gconfig-object.c @@ -284,6 +284,8 @@ gvir_config_object_get_xml_doc(GVirConfigObject *config) G_GNUC_INTERNAL xmlNodePtr gvir_config_object_get_xml_node(GVirConfigObject *config) { + g_return_val_if_fail(GVIR_CONFIG_IS_OBJECT(config), NULL); + return config->priv->node; } -- 2.7.4
