Async signals and various bugfixes and testing by Ross Burton <ross@burtonini.com>. * glib/dbus-gvalue.h: (struct DBusBasicGValue): Delete. (dbus_gvalue_genmarshal_name_from_type) (dbus_gvalue_ctype_from_type): Moved to dbus-binding-tool-glib.c. (dbus_gtype_to_dbus_type): Renamed to dbus_gtype_from_signature. (dbus_g_value_types_init, dbus_gtype_from_signature) (dbus_gtype_from_signature_iter, dbus_gtype_to_signature) (dbus_gtypes_from_arg_signature): New function prototypes. (dbus_gvalue_demarshal): Take context and error arguments. (dbus_gvalue_demarshal_variant): New function. (dbus_gvalue_demarshal_message): New function. (dbus_gvalue_store): Delete. * glib/dbus-gvalue.c: File has been almost entirely rewritten; now we special-case more types such as DBUS_TYPE_SIGNATURE, handle arrays and hash tables correctly, etc. Full support for recursive values is not yet complete. * glib/dbus-gproxy.c (dbus_g_proxy_class_init): Change last argument of signal to G_TYPE_POINTER since we now pass a structure. (lookup_g_marshaller): Delete in favor of _dbus_gobject_lookup_marshaller. (marshal_dbus_message_to_g_marshaller): Use _dbus_gobject_lookup_marshaller and dbus_gvalue_demarshal_message to handle remote signal callbacks. (dbus_g_proxy_new_from_proxy): New function; creates a new DBusGProxy by copying an existing one. (dbus_g_proxy_get_interface, dbus_g_proxy_set_interface) (dbus_g_proxy_get_path): New functions. (dbus_g_proxy_marshal_args_to_message): New function; factored out of existing code. (DBUS_G_VALUE_ARRAY_COLLECT_ALL): Collect all arguments from a varargs array. (dbus_g_proxy_begin_call_internal): New function. (dbus_g_proxy_end_call_internal): New function. (dbus_g_proxy_begin_call): Take GTypes instead of DBus types as arguments; simply invoke dbus_g_proxy_begin_call_internal after collecting args into value array. (dbus_g_proxy_end_call): Take GTypes instead of DBus types; invoke dbus_g_proxy_end_call_internal. (dbus_g_proxy_invoke): Simply invoke begin_call_interanl and end_call_internal. (dbus_g_proxy_call_no_reply): Take GTypes instead of DBus types. (array_free_all): New function. (dbus_g_proxy_add_signal): Take GTypes. * glib/dbus-gobject.h: (_dbus_glib_marshal_dbus_message_to_gvalue_array): Delete. (_dbus_gobject_get_path, _dbus_gobject_lookup_marshaller): Prototype. * glib/dbus-gobject.c: Add a global marshal_table hash which stores mappings from type signatures to marshallers. Change lots of invocations of dbus_gtype_to_dbus_type to dbus_gtype_to_signature. (_dbus_glib_marshal_dbus_message_to_gvalue_array): Delete. (introspect_signals): Fix test for query.return_type. (set_object_property): Update invocation of dbus_gvalue_demarshal. (invoke_object_method): Many changes. Handle asynchronous invocations. Convert arguments with dbus_gvalue_demarshal_message. Handle errors. Use DBusSignatureIter instead of strlen on args. Handle all arguments generically. Special-case variants. (dbus_g_method_return, dbus_g_method_return_error): New function. (DBusGSignalClosure): New structure, closes over signal information. (dbus_g_signal_closure_new): New function. (dbus_g_signal_closure_finalize): New function. (signal_emitter_marshaller): New function; is special marshaller which emits signals on bus. (export_signals): New function; introspects object signals and connects to them. (dbus_g_object_type_install_info): Take GType instead of GObjectClass. (dbus_g_connection_register_g_object): Invoke export_signals. (dbus_g_connection_lookup_g_object): New function. (DBusGFuncSignature) New structure; used for mapping type signatures to marshallers. (funcsig_hash): New function; hashes DBusGFuncSignature. (funcsig_equal): New function; compares DBusGFuncSignature. (_dbus_gobject_lookup_marshaller): New function. (dbus_g_object_register_marshaller): New function; used to register a marshaller at runtime for a particular signature. * glib/dbus-gmain.c (_dbus_gmain_test): Add various tests. * glib/dbus-binding-tool-glib.h: Add DBUS_GLIB_ANNOTATION_ASYNC which notes a server method implementation should be asynchronous. * glib/dbus-binding-tool-glib.c (dbus_binding_tool_output_glib_server): Call dbus_g_value_types_init. (write_formal_parameters): Use dbus_gtype_from_signature. Handle variants specially. (dbus_g_type_get_lookup_function): Turn GType into an invocation of a lookup function. (write_args_for_direction): Use dbus_g_type_get_lookup_function. (write_untyped_out_args): New method; write output arguments. (write_formal_declarations_for_direction): Function for writing prototypes. (write_formal_parameters_for_direction): Function for writing implementations. (write_typed_args_for_direction): Function for writing arguments prefixed with GTypes. (write_async_method_client): Write out async version of method. * glib/dbus-binding-tool-glib.c: Include dbus-gvalue-utils.h. (dbus_g_type_get_marshal_name): Move mapping from GType to marshal name into here. (dbus_g_type_get_c_name): Move into here. (compute_marshaller): Convert signature to type with dbus_gtype_from_signature, use dbus_g_type_get_marshal_name. (compute_marshaller_name): Ditto. (compute_marshaller): Handle async signal annotations. (gather_marshallers): Return if we don't have a known prefix. (generate_glue): Collect introspection blob here, and write all of the blob at the end. This allows an object with multiple interfaces to work. Mark async methods in introspection blob. * glib/Makefile.am (libdbus_glib_1_la_SOURCES): Add dbus-gtype-specialized.c, dbus-gtype-specialized.h, dbus-gvalue-utils.h, dbus-gvalue-utils.c. * dbus/dbus-glib.h: Don't include dbus-protocol.h; this avoids people accidentally using DBUS_TYPE_* which should not be necessary anymore. Do include dbus-gtype-specialized.h, which are utilities for GLib container types. Add various #defines for types such as DBUS_TYPE_G_BOOLEAN_ARRAY. (DBusGValueIterator, DBusGValue): Define, not fully used yet. (dbus_g_value_get_g_type): Type for recursive value. (dbus_g_value_open, dbus_g_value_iterator_get_value) (dbus_g_value_iterator_get_values, dbus_g_value_iterator_recurse) (dbus_g_value_free): Prototypes. (dbus_g_object_register_marshaller, dbus_g_proxy_new_from_proxy): Prototype. (dbus_g_proxy_set_interface): Prototype. (dbus_g_proxy_begin_call, dbus_g_proxy_end_call) (dbus_g_proxy_call_no_reply): Take GLib types instead of DBus types. (dbus_g_proxy_get_path, dbus_g_proxy_get_interface): Accessors. (DBusGAsyncData, DBusGMethodInvocation): Structures for doing async invocations. (dbus_g_method_return, dbus_g_method_return_error): Prototypes. * doc/dbus-tutorial.xml: Update GLib section. * tools/dbus-viewer.c (load_child_nodes): Update for new invocation type of dbus_g_proxy_end_call. (load_from_service_thread_func): Ditto. * tools/print-introspect.c (main): Ditto. * tools/dbus-names-model.c (have_names_notify) (names_model_reload, names_model_set_connection) Use GTypes. * python/Makefile.am (INCLUDES): Define DBUS_COMPILATION, needed since Python bindings use GLib bindings. * test/glib/Makefile.am (INCLUDES): Define DBUS_COMPILATION. Add --prefix argument. * tools/Makefile.am: Define DBUS_COMPILATION. Remove unneeded --ignore-unsupported arg. * test/glib/test-service-glib.c: * test/glib/test-service-glib.xml: * test/glib/test-dbus-glib.c: Add many more tests.
