Overview

Emitted when a method is invoked by a remote caller and used to determine if the method call is authorized.

Note that this signal is emitted in a thread dedicated to handling the method call so handlers are allowed to perform blocking IO. This means that it is appropriate to call e.g. polkit_authority_check_authorization_sync() with the POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION flag set.

If false is returned then no further handlers are run and the signal handler must take a reference to invocation and finish handling the call (e.g. return an error via g_dbus_method_invocation_return_error()).

Otherwise, if true is returned, signal emission continues. If no handlers return false, then the method is dispatched. If interface has an enclosing #GDBusObjectSkeleton, then the #GDBusObjectSkeleton::authorize-method signal handlers run before the handlers for this signal.

The default class handler just returns true.

Please note that the common case is optimized: if no signals handlers are connected and the default class handler isn't overridden (for both interface and the enclosing #GDBusObjectSkeleton, if any) and #GDBusInterfaceSkeleton:g-flags does not have the %G_DBUS_INTERFACE_SKELETON_FLAGS_HANDLE_METHOD_INVOCATIONS_IN_THREAD flags set, no dedicated thread is ever used and the call will be handled in the same thread as the object that interface belongs to was exported in.
