Havoc Pennington d8155bf51b 2006-09-30 Havoc Pennington <hp@redhat.com>
* configure.in (LT_CURRENT, LT_AGE): increment current and age to
	reflect addition of interfaces.

	* doc/dbus-specification.xml: describe a new
	org.freedesktop.DBus.Peer.GetMachineId method

	* dbus/dbus-string.c (_dbus_string_skip_white_reverse): new function
	(_dbus_string_skip_white, _dbus_string_skip_blank): use new
	DBUS_IS_ASCII_BLANK, DBUS_IS_ASCII_WHITE macros and fix assertion
	at end of skip_white
	(_dbus_string_chop_white): new function

	* bus/connection.c (bus_connections_setup_connection): call
	dbus_connection_set_route_peer_messages.

	* dbus/dbus-connection.c
	(_dbus_connection_peer_filter_unlocked_no_update): modify to
	support a GetMachineId method.

	Also, support a new flag to let the bus pass peer methods through
	to apps on the bus, which can be set with
	dbus_connection_set_route_peer_messages.

	Finally, handle and return an error for anything unknown on the
	Peer interface, which will allow us to extend the Peer interface
	in the future without fear that we're now intercepting something
	apps were wanting to see.

	* tools/dbus-uuidgen.c: a thin wrapper around the functions in
	dbus/dbus-uuidgen.c

	* dbus/dbus-uuidgen.c: implement the bulk of the dbus-uuidgen
	binary here, since most of the code is already in libdbus

	* dbus/dbus-sysdeps.c (_dbus_read_local_machine_uuid): read the
	uuid from the system config file

	* dbus/dbus-internals.c (_dbus_generate_uuid, _dbus_uuid_encode)
	(_dbus_read_uuid_file_without_creating)
	(_dbus_create_uuid_file_exclusively, _dbus_read_uuid_file): new
	uuid-related functions, partly factored out from dbus-server.c

	* dbus/dbus-sysdeps.c (_dbus_error_from_errno): convert EEXIST to
	DBUS_ERROR_FILE_EXISTS instead of EEXIST

	* dbus/dbus-protocol.h (DBUS_ERROR_FILE_EXISTS): add file exists error

	* tools/dbus-cleanup-sockets.1: explain what the point of this
	thing is a bit more

	* autogen.sh (run_configure): add --config-cache to default
	configure args

	* dbus/dbus-internals.h (_DBUS_ASSERT_ERROR_IS_SET): disable the
	error set/clear assertions when DBUS_DISABLE_CHECKS is defined

	* tools/dbus-launch.c (main): if xdisplay hasn't been opened,
	don't try to save address, fixes crash in make check
