* Merge dbus-object-names branch. To see the entire patch do cvs diff -r DBUS_OBJECT_NAMES_BRANCHPOINT -r dbus-object-names, it's huuuuge though. To revert, I tagged DBUS_BEFORE_OBJECT_NAMES_MERGE. 2003-09-28 Havoc Pennington <hp@pobox.com> * HACKING: update to reflect new server 2003-09-26 Seth Nickell <seth@gnome.org> * python/dbus.py: * python/examples/example-signals.py: Start implementing some notions of signals. The API is really terrible, but they sort of work (with the exception of being able to filter by service, and to transmit signals *as* a particular service). Need to figure out how to make messages come from the service we registered :-( * python/dbus_bindings.pyx.in: Removed duplicate message_handler callbacks. 2003-09-25 Havoc Pennington <hp@redhat.com> * bus/session.conf.in: fix my mess 2003-09-25 Havoc Pennington <hp@pobox.com> * bus/session.conf.in: fix security policy, reported by Seth Nickell 2003-09-25 Seth Nickell <seth@gnome.org> * python/examples/example-service.py: Johan notices complete wrong code in example-service, but completely wrong in a way that works exactly the same (!). Johan is confused, how could this possibly work? Example code fails to serve purpose of making things clear. Seth fixes. 2003-09-25 Mark McLoughlin <mark@skynet.ie> * doc/dbus-specification.sgml: don't require header fields to be 4-byte aligned and specify that fields should be distinguished from padding by the fact that zero is not a valid field name. * doc/TODO: remove re-alignment item and add item to doc the OBJECT_PATH type. * dbus/dbus-message.c: (HeaderField): rename the original member to value_offset and introduce a name_offset member to keep track of where the field actually begins. (adjust_field_offsets): remove. (append_int_field), (append_uint_field), (append_string_field): don't align the start of the header field to a 4-byte boundary. (get_next_field): impl finding the next marhsalled field after a given field. (re_align_field_recurse): impl re-aligning a number of already marshalled fields. (delete_field): impl deleting a field of any type and re-aligning any following fields. (delete_int_or_uint_field), (delete_string_field): remove. (set_int_field), (set_uint_field): no need to re-check that we have the correct type for the field. (set_string_field): ditto and impl re-aligning any following fields. (decode_header_data): update to take into account that the fields aren't 4-byte aligned any more and the new way to distinguish padding from header fields. Also, don't exit when there is too much header padding. (process_test_subdir): print the directory. (_dbus_message_test): add test to make sure a following field is re-aligned correctly after field deletion. * dbus/dbus-string.[ch]: (_dbus_string_insert_bytes): rename from insert_byte and allow the insert of multiple bytes. (_dbus_string_test): test inserting multiple bytes. * dbus/dbus-marshal.c: (_dbus_marshal_set_string): add warning note to docs about having to re-align any marshalled values following the string. * dbus/dbus-message-builder.c: (append_string_field), (_dbus_message_data_load): don't align the header field. * dbus/dbus-auth.c: (process_test_subdir): print the directory. * test/break-loader.c: (randomly_add_one_byte): upd. for insert_byte change. * test/data/invalid-messages/bad-header-field-alignment.message: new test case. * test/data/valid-messages/unknown-header-field.message: shove a dict in the unknown field. 2003-09-25 Seth Nickell <seth@gnome.org> * python/dbus.py: * python/dbus_bindings.pyx.in: Handle return values. * python/examples/example-client.py: * python/examples/example-service.py: Pass back return values from the service to the client. 2003-09-24 Seth Nickell <seth@gnome.org> * python/dbus.py: Connect Object methods (when you are sharing an object) up... pass in a list of methods to be shared. Sharing all the methods just worked out too weird. You can now create nice Services over the DBus in Python. :-) * python/dbus_bindings.pyx.in: Keep references to user_data tuples passed into C functions so Python doesn't garbage collect on us. Implement MethodReturn and Error subclasses of Message for creating DBusMessage's of those types. * python/examples/example-client.py: * python/examples/example-service.py: Simple example code showing both how create DBus services and objects, and how to use them. 2003-09-23 Havoc Pennington <hp@pobox.com> * glib/dbus-gproxy.c (dbus_gproxy_manager_filter): implement 2003-09-23 Havoc Pennington <hp@redhat.com> * glib/dbus-gproxy.c (dbus_gproxy_connect_signal): implement (dbus_gproxy_disconnect_signal): implement (dbus_gproxy_manager_remove_signal_match): implement (dbus_gproxy_manager_add_signal_match): implement (dbus_gproxy_oneway_call): implement 2003-09-23 Havoc Pennington <hp@pobox.com> * glib/dbus-gproxy.c (struct DBusGProxy): convert to a GObject subclass. This means dropping the transparent thread safety of the proxy; you now need a separate proxy per-thread, or your own locking on the proxy. Probably right anyway. (dbus_gproxy_ref, dbus_gproxy_unref): nuke, just use g_object_ref 2003-09-22 Havoc Pennington <hp@redhat.com> * glib/dbus-gproxy.c (dbus_gproxy_manager_get): implement 2003-09-21 Seth Nickell <seth@gnome.org> First checkin of the Python bindings. * python/.cvsignore: * python/Makefile.am: * python/dbus_bindings.pyx.in: * python/dbus_h_wrapper.h: Pieces for Pyrex to operate on, building a dbus_bindings.so python module for low-level access to the DBus APIs. * python/dbus.py: High-level Python module for accessing DBus objects. * configure.in: * Makefile.am: Build stuff for the python bindings. * acinclude.m4: Extra macro needed for finding the Python C header files. 2003-09-21 Havoc Pennington <hp@pobox.com> * glib/dbus-gproxy.c (dbus_gproxy_manager_new): start implementing the proxy manager, didn't get very far. * dbus/dbus-bus.c (dbus_bus_add_match): new (dbus_bus_remove_match): new * glib/dbus-gproxy.c (dbus_gproxy_new_for_service): add a path_name argument; adjust the other not-yet-implemented gproxy constructors to be what I think they should be. 2003-09-21 Havoc Pennington <hp@pobox.com> * dbus/dbus-bus.c (dbus_bus_get): set exit_on_disconnect to TRUE by default for message bus connections. * dbus/dbus-connection.c (dbus_connection_dispatch): exit if exit_on_disconnect flag is set and we process the disconnected signal. (dbus_connection_set_exit_on_disconnect): new function 2003-09-21 Havoc Pennington <hp@pobox.com> Get matching rules mostly working in the bus; only actually parsing the rule text remains. However, the client side of "signal connections" hasn't been started, this patch is only the bus side. * dbus/dispatch.c: fix for the matching rules changes * bus/driver.c (bus_driver_handle_remove_match) (bus_driver_handle_add_match): send an ack reply from these method calls * glib/dbus-gproxy.c (dbus_gproxy_begin_call): fix order of arguments, reported by Seth Nickell * bus/config-parser.c (append_rule_from_element): support eavesdrop=true|false attribute on policies so match rules can be prevented from snooping on the system bus. * bus/dbus-daemon-1.1.in: consistently use terminology "sender" and "destination" in attribute names; fix some docs bugs; add eavesdrop=true|false attribute * bus/driver.c (bus_driver_handle_add_match) (bus_driver_handle_remove_match): handle AddMatch, RemoveMatch messages * dbus/dbus-protocol.h (DBUS_SERVICE_ORG_FREEDESKTOP_BROADCAST): get rid of broadcast service concept, signals are just always broadcast * bus/signals.c, bus/dispatch.c, bus/connection.c, bus/bus.c: mostly implement matching rules stuff (currently only exposed as signal connections) 2003-09-21 Mark McLoughlin <mark@skynet.ie> * doc/dbus-specification.sgml: Change the header field name to be an enum and update the rest of the spec to reference the fields using the conventinal name. * dbus/dbus-protocol.h: update to reflect the spec. * doc/TODO: add item to remove the 4 byte alignment requirement. * dbus/dbus-message.c: Remove the code to generalise the header/body length and serial number header fields as named header fields so we can reference field names using the protocol values. (append_int_field), (append_uint_field), (append_string_field): Append the field name as a byte rather than four chars. (delete_int_or_uint_field), (delete_string_field): reflect the fact that the field name and typecode now occupy 4 bytes instead of 8. (decode_string_field), (decode_header_data): update to reflect protocol changes and move the field specific encoding from decode_string_field() back into decode_header_data(). * dbus/dbus-internals.[ch]: (_dbus_header_field_to_string): Add utility to aid debugging. * dbus/dbus-message-builder.c: (append_string_field), (_dbus_message_data_load): Update to reflect protocol changes; Change the FIELD_NAME directive to HEADER_FIELD and allow it to take the field's conventional name rather than the actual value. * test/data/*/*.message: Update to use HEADER_FIELD instead of FIELD_NAME; Always align the header on an 8 byte boundary *before* updating the header length. 2003-09-15 Havoc Pennington <hp@pobox.com> * dbus/dbus-pending-call.c: add the get/set object data boilerplate as for DBusConnection, etc. Use generic object data for the notify callback. * glib/dbus-gparser.c (parse_node): parse child nodes * tools/dbus-viewer.c: more hacking on the dbus-viewer * glib/dbus-gutils.c (_dbus_gutils_split_path): add a file to contain functions shared between the convenience lib and the installed lib * glib/Makefile.am (libdbus_glib_1_la_LDFLAGS): add -export-symbols-regex to the GLib library * dbus/dbus-object-tree.c (_dbus_object_tree_dispatch_and_unlock): fix the locking in here, and add a default handler for Introspect() that just returns sub-nodes. 2003-09-14 Havoc Pennington <hp@pobox.com> * glib/dbus-gthread.c (dbus_g_thread_init): rename to make g_foo rather than gfoo consistent * glib/dbus-gproxy.h: delete for now, move contents to dbus-glib.h, because the include files don't work right since we aren't in the dbus/ subdir. * glib/dbus-gproxy.c (dbus_gproxy_send): finish implementing (dbus_gproxy_end_call): finish (dbus_gproxy_begin_call): finish * glib/dbus-gmain.c (dbus_set_g_error): new * glib/dbus-gobject.c (handle_introspect): include information about child nodes in the introspection * dbus/dbus-connection.c (dbus_connection_list_registered): new function to help in implementation of introspection * dbus/dbus-object-tree.c (_dbus_object_tree_list_registered_and_unlock): new function 2003-09-12 Havoc Pennington <hp@pobox.com> * glib/dbus-gidl.h: add common base class for all the foo_info types * tools/dbus-viewer.c: add GTK-based introspection UI thingy similar to kdcop * test/Makefile.am: try test srcdir -ef . in addition to test srcdir = ., one of them should work (yeah lame) * glib/Makefile.am: build the "idl" parser stuff as a convenience library * glib/dbus-gparser.h: make description_load routines return NodeInfo* not Parser* * Makefile.am (SUBDIRS): build test dir after all library dirs * configure.in: add GTK+ detection 2003-09-07 Havoc Pennington <hp@pobox.com> * Make Doxygen contented. 2003-09-07 Havoc Pennington <hp@pobox.com> * doc/dbus-specification.sgml: more updates 2003-09-06 Havoc Pennington <hp@pobox.com> * doc/dbus-specification.sgml: partial updates * bus/dbus-daemon-1.1.in: fix the config file docs for the zillionth time; hopefully I edited the right file this time. * bus/config-parser.c (append_rule_from_element): support send_type, send_path, receive_type, receive_path * bus/policy.c: add message type and path to the list of things that can be "firewalled" 2003-09-06 Havoc Pennington <hp@pobox.com> * dbus/dbus-connection.c (dbus_connection_register_fallback): add this (dbus_connection_register_object_path): make this not handle messages to paths below the given path 2003-09-03 Havoc Pennington <hp@pobox.com> * test/glib/Makefile.am: add this with random glib-linked test programs * glib/Makefile.am: remove the random test programs from here, leave only the unit tests * glib/dbus-gobject.c (_dbus_gobject_test): add test for uscore/javacaps conversion, and fix (get_object_property, set_object_property): change to .NET convention for mapping props to methods, set_FooBar/get_FooBar, since one language has such a convention we may as well copy it.
