Subject: 2003-04-06  Havoc Pennington  <hp@pobox.com>

	* bus/bus.c (bus_context_new): fix wrong handling of
	server_data_slot_unref() in the error case.

	* dbus/dbus-internals.h (_dbus_assert): change so it passes
	"(condition) != 0" to _dbus_real_assert so that
	"_dbus_assert (pointer)" doesn't cause a warning

	* bus/main.c (main): accept --print-address option to print out
	the message bus address

	* dbus/dbus-sysdeps.c (_dbus_generate_random_ascii): export this

	* dbus/dbus-transport.c (_dbus_transport_open): special error for
	"tmpdir" option to unix: address on client side

	* dbus/dbus-server.c (dbus_server_listen): handle "tmpdir" option
	to unix: address

	* configure.in (TEST_SOCKET_DIR): locate a temporary directory
	we can use to create sockets in the test suite.

	* bus/main.c (signal_handler): on SIGTERM, exit the daemon
	cleanly. To be used for testing.

	* dbus/dbus-spawn.c (babysit): use _dbus_set_signal_handler()

	* dbus/dbus-sysdeps.c (_dbus_set_signal_handler): new

	* dbus/dbus-server-debug-pipe.c (_dbus_transport_debug_pipe_new):
	handle trying to call this when there's no servers active
