From e888647a70094d5761f931e1a812764330ee5a2b Mon Sep 17 00:00:00 2001 From: Colin Walters Date: Fri, 8 Jul 2005 16:25:39 +0000 Subject: 2005-07-08 Colin Walters * tools/Makefile.am: Kill of print-introspect in favor of using dbus-send --print-reply=literal. * tools/print-introspect.c: Deleted. * test/glib/test-service-glib.xml: * test/glib/test-service-glib.c (my_object_get_objs): New test for "ao". * test/glib/test-dbus-glib.c (echo_received_cb): Free echo data. (main): Test GetObjs. * glib/examples/statemachine/Makefile.am: * glib/examples/statemachine/sm-marshal.list: * glib/examples/statemachine/statemachine-client.c: * glib/examples/statemachine/statemachine-server.c: * glib/examples/statemachine/statemachine-server.xml: * glib/examples/statemachine/statemachine.c: * glib/examples/statemachine/statemachine.h: * glib/examples/statemachine/statemachine.xml: New example. * glib/examples/example-service.c (main): Move invocation of dbus_g_object_type_install_info earlier, to emphasize it should only be done once. * glib/examples/example-signal-emitter.c (main): Ditto. * glib/examples/Makefile.am (SUBDIRS): Include statemachine. * glib/dbus-gvalue.h (dbus_gtype_to_signature) (dbus_gvalue_marshal): Update prototypes. * glib/dbus-gvalue.c: Update all marshalling functions to take const GValue instead of GValue. (signature_iter_to_g_type_array): Return a GPtrArray for nonfixed types. (dbus_gvalue_to_signature): Update for dbus_gtype_to_signature change. (dbus_gtype_to_signature): Handle generic collecitons and maps. Return a newly-allocated string. (demarshal_proxy, demarshal_object_path, demarshal_object) (demarshal_strv, demarshal_ghashtable): Set error, don't assert if we get the wrong types from message. (get_type_demarshaller): New function, extracted from dbus_gvalue_demarshal. (demarshal_collection): New function, demarshals generic collection. (dbus_gvalue_demarshal): Just invoke result of get_type_demarshaller. Throw error if we don't have one. (marshal_garray_basic): Abort on OOM. (get_type_marshaller): New function, extracted from dbus_gvalue_marshal. (collection_marshal_iterator, marshal_collection): New functions; implements generic marshalling for an iteratable specialized collection. (dbus_gvalue_marshal): Just invoke result of get_type_marshaller. * glib/dbus-gvalue-utils.c (gvalue_from_ptrarray_value): Handle G_TYPE_STRING. (ptrarray_value_from_gvalue): Ditto. (ptrarray_append, ptrarray_free): New functions. (slist_constructor, slist_iterator, slist_copy_elt, slist_copy) (slist_append, slist_end_append, slist_free): New functions. (dbus_g_type_specialized_builtins_init): Add append fuctions for GPtrArray and GSList. Register GSList. (test_specialized_hash, _dbus_gvalue_utils_test): New functions. * glib/dbus-gtype-specialized.h (DBusGTypeSpecializedAppendContext): New. (dbus_g_type_specialized_collection_init_append) (dbus_g_type_specialized_collection_append) (dbus_g_type_specialized_collection_end_append): Prototype. (DBusGTypeSpecializedCollectionVtable): Add append_func and end_append_func. * glib/dbus-gtype-specialized.c (dbus_g_type_specialized_collection_init_append) (dbus_g_type_specialized_collection_append) (dbus_g_type_specialized_collection_end_append): New functions. (dbus_g_type_map_value_iterate): Take const GValue. (dbus_g_type_collection_value_iterate): Ditto. * glib/dbus-gtest.c (dbus_glib_internal_do_not_use_run_tests): Run _dbus_gvalue_utils_test. * glib/dbus-gtest.h: Prototype it. * glib/dbus-gproxy.c (dbus_g_proxy_manager_filter): Avoid using uninitialized owner_list. (dbus_g_proxy_begin_call_internal): Move return_if_fail to public API. (dbus_g_proxy_end_call_internal): Update to use error set from dbus_gvalue_demarshal instead of setting it here. (dbus_g_proxy_begin_call): Move return_if_fail here. * glib/dbus-gobject.c (write_interface): Update for dbus_gtype_to_signature returning new string. * configure.in: Add glib/examples/statemachine. --- glib/examples/statemachine/statemachine-server.c | 202 +++++++++++++++++++++++ 1 file changed, 202 insertions(+) create mode 100644 glib/examples/statemachine/statemachine-server.c (limited to 'glib/examples/statemachine/statemachine-server.c') diff --git a/glib/examples/statemachine/statemachine-server.c b/glib/examples/statemachine/statemachine-server.c new file mode 100644 index 00000000..7cadf1fe --- /dev/null +++ b/glib/examples/statemachine/statemachine-server.c @@ -0,0 +1,202 @@ +#include +#include +#include + +#include "statemachine.h" +#include "sm-marshal.h" +#include "statemachine-server.h" + +enum +{ + PROP_O, + PROP_BUS +};
