Those structs are for DBusTransport internal use, they should not be
referenced outside it.
The transport needs only to allocate memory on initialization and free
it on finalization.
The lifecycle for the two allocated structs is DBusTransport lifecycle
and at DBusTransport's finalization its connection is already
disconnected.
The assumption is that the transport owns a reference for any object the
two structs holds a reference for (particularly DBusConnection)

Windows also has numeric process IDs that fit in an unsigned long, so
there's no reason this has to be Unix-specific.

* dbus/dbus-auth.c: adapt to keyring changes
* dbus/dbus-keyring.c: change to avoid using user ID and home
directory directly; instead use a
keyring-location-from-credentials function in dbus-sysdeps
* fix to use _dbus_append_user_from_current_process() instead of
_dbus_username_from_current_process() or _dbus_append_desired_identity().
It needs to much tests to verify that the change does not break anything. I had overseen that the signatures are different (** to *) which requires non trivial changes. This is one *major* disadvantage of elumating oop functionality with c. You are responsible for cleaning every object on every function return point, which could be a nightmare if you are not working with dbus all the days.
* dbus/dbus-auth.c (sha1_handle_second_client_response)
(handle_server_data_anonymous_mech): add the process ID from
socket credentials, if available, even if not using EXTERNAL
* dbus/dbus-transport.c (auth_via_default_rules): support
allow_anonymous flag
* dbus/dbus-connection.c (dbus_connection_get_is_anonymous)
(dbus_connection_set_allow_anonymous): new API for controlling
anonymous access
* dbus/dbus-string.c (_dbus_string_pop_line): fix this not to
think an empty line is the end of the file.
Also, fix some whitespace.
* dbus/dbus-string-util.c: add more tests for
_dbus_string_pop_line() revealing that it thinks an empty line is
the end of the file, which broke dbus-auth-script.c so
it didn't really run the scripts
* dbus/dbus-auth.c: add ANONYMOUS mechanism
* dbus/dbus-auth-script.c (_dbus_auth_script_run): fix to detect
an empty/no-op auth script; add commands to check that we have or
don't have the expected credentials
* bus/dispatch.c (check_get_connection_unix_process_id): adapt
since sysdeps-unix.h stuff isn't included anymore
* bus/bus.c (bus_context_new): use more abstract functions to
change user, so they can be no-ops on Windows
* dbus/dbus-credentials.c, dbus/dbus-credentials.h,
dbus/dbus-credentials-util.c: new files containing a fully opaque
DBusCredentials data type to replace the old not opaque one.
* configure.in (DBUS_UNIX): define DBUS_UNIX to match DBUS_WIN on
windows
* dbus/dbus-userdb.h: prohibit on Windows, next step is to clean
up the uses of it in bus/*.c and factor out the parts of
cookie auth that depend on it
* doc/TODO: remove the "guid" item
* test/glib/test-profile.c (no_bus_thread_func): use open_private
(with_bus_thread_func): use open_private
* dbus/dbus-connection.c (dbus_connection_open_private): new
function that works like the old dbus_connection_open()
(dbus_connection_open): now returns an existing connection if
possible
* dbus/dbus-server-unix.c (handle_new_client_fd_and_unlock): pass
through the GUID to the transport
* dbus/dbus-server.c (_dbus_server_init_base): keep around the
GUID in hex-encoded form.
* dbus/dbus-server-debug-pipe.c (_dbus_transport_debug_pipe_new):
pass GUID argument in to the transport
* dbus/dbus-transport-unix.c (_dbus_transport_new_for_fd): add
guid argument
* dbus/dbus-transport.c (_dbus_transport_init_base): add guid argument
* dbus/dbus-auth.c (_dbus_auth_server_new): add guid argument
* Land the new message args API and type system.
This patch is huge, but the public API change is not
really large. The set of D-BUS types has changed somewhat,
and the arg "getters" are more geared toward language bindings;
they don't make a copy, etc.
There are also some known issues. See these emails for details
on this huge patch:
http://lists.freedesktop.org/archives/dbus/2004-December/001836.htmlhttp://lists.freedesktop.org/archives/dbus/2005-January/001922.html
* dbus/dbus-marshal-*: all the new stuff
* dbus/dbus-message.c: basically rewritten
* dbus/dbus-memory.c (check_guards): with "guards" enabled, init
freed blocks to be all non-nul bytes so using freed memory is less
likely to work right
* dbus/dbus-internals.c (_dbus_test_oom_handling): add
DBUS_FAIL_MALLOC=N environment variable, so you can do
DBUS_FAIL_MALLOC=0 to skip the out-of-memory checking, or
DBUS_FAIL_MALLOC=10 to make it really, really, really slow and
thorough.
* qt/message.cpp: port to the new message args API
(operator<<): use str.utf8() rather than str.unicode()
(pretty sure this is right from the Qt docs?)

* bus/dispatch.c, bus/driver.c: port to the new message args API
* dbus/dbus-string.c (_dbus_string_init_const_len): initialize the

assume there might be unused bytes.
* dbus/dbus-auth.c (_dbus_auth_do_work): Remove check for
client-out-of-mechs, it is handled in process_reject(). Move check
for max failures to send_rejected(), as it's a server-only thing.

where we tried to use transport->connection that was NULL,

* dbus/dbus-bus.c: adapt to API changes, make it use DBusError not
DBusResultCode
* dbus/dbus-connection.c (dbus_connection_send): drop the result
code here, as the only failure possible is OOM.
* bus/connection.c (bus_connection_disconnect):
rename bus_connection_disconnected as it's a notification only
* bus/driver.c (bus_driver_handle_acquire_service): don't free
"name" on get_args failure, should be done by get_args;
don't disconnect client for bad args, just return an error.

dbus-internals.h, multiple prototypes was confusing doxygen
besides being kind of ugly
* Doxyfile (PREDEFINED): have Doxygen define
DOXYGEN_SHOULD_SKIP_THIS so we can exclude things from
docs with #ifndef DOXYGEN_SHOULD_SKIP_THIS

documenting...)

dbus_credentials_match were backward
