* Throughout, grand renaming to strip out the use of "service",
just say "name" instead (or "bus name" when ambiguous). Did not
change the internal code of the message bus itself, only the
programmer-facing API and messages.
* doc/dbus-specification.xml: further update the message bus section
* bus/config-parser.c (all_are_equiv): fix bug using freed string
in error case
* 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?)
* glib/dbus-gvalue.c: port to the new message args API
* bus/dispatch.c, bus/driver.c: port to the new message args API
* dbus/dbus-string.c (_dbus_string_init_const_len): initialize the
"locked" flag to TRUE and align_offset to 0; I guess we never
looked at these anyhow, but seems cleaner.
* dbus/dbus-string.h (_DBUS_STRING_ALLOCATION_PADDING):
move allocation padding macro to this header; use it to implement
(_DBUS_STRING_STATIC): ability to declare a static string.
* dbus/dbus-message.c (_dbus_message_has_type_interface_member):
change to return TRUE if the interface is not set.
* dbus/dbus-string.[hc]: move the D-BUS specific validation stuff
to dbus-marshal-validate.[hc]
* dbus/dbus-marshal-basic.c (_dbus_type_to_string): move here from
dbus-internals.c
* dbus/Makefile.am: cut over from dbus-marshal.[hc]
to dbus-marshal-*.[hc]
* dbus/dbus-object-tree.c (_dbus_decompose_path): move this
function here from dbus-marshal.c
backend for config file loader. Doesn't work with full OOM test yet.
* configure.in: change error when selecting libxml into a warning.
* test/data/invalid-config-files: add two non-well-formed XML files.
* glib/Makefile.am: libdbus_gtool always uses expat, not libxml.
* dbus/dbus-transport-unix.c (unix_handle_watch): do not disconnect in
case of DBUS_WATCH_HANGUP, several do_reading() may be necessary to
read all the buffer. (bug #894)
* bus/activation.c (bus_activation_activate_service): fix a potential
assertion failure (bug #896). Small optimization in the case of
auto-activation messages.
* dbus/dbus-message.c (verify_test_message, _dbus_message_test): add
test case for byte-through-vararg bug (#901). patch by Kimmo
Hämäläinen.
* bus/activation.c:
(babysitter_watch_callback): notify all pending activations waiting for
the same exec that the activation failed.
(bus_activation_activate_service): shortcut the activation if we
already waiting for the same executable to start up.
* bus/activation.c:
- Added service file reloading.
Each service files directory is kept in an hash table in
BusActivation and each BusActivationEntry knows what .service-file it
was read from. So when you try to activate a service the bus will
check if it's been updated, removed or if new .service-files has
been installed.
- Test code at the bottom for the service file reloading.
* bus/test-main.c: (main):
* bus/test.h:
- added service reloading test.

* dbus/dbus-sysdeps.h: (_dbus_delete_directory): Added.
* bus/connection.c (bus_pending_reply_expired): either cancel or
execute, not both
(bus_connections_check_reply): use unlink, not remove_link, as we
don't want to free the link; fixes double free mess
* dbus/dbus-pending-call.c (dbus_pending_call_block): fix in case
where no reply was received
* dbus/dbus-connection.c (_dbus_pending_call_complete_and_unlock):
fix a refcount leak
* bus/signals.c (match_rule_matches): add special cases for the
bus driver, so you can match on sender/destination for it.
* dbus/dbus-sysdeps.c (_dbus_abort): print backtrace if
DBUS_PRINT_BACKTRACE is set
* dbus/dbus-internals.c: add pid to assertion failure messages
* dbus/dbus-connection.c: add message type code to the debug spew

sender=foo not service=foo
* dbus/dbus-bus.c (dbus_bus_get): if the activation bus is the
session bus but DBUS_SESSION_BUS_ADDRESS isn't set, use
DBUS_ACTIVATION_ADDRESS instead
* bus/activation.c: set DBUS_SESSION_BUS_ADDRESS,
DBUS_SYSTEM_BUS_ADDRESS if appropriate
* bus/bus.c (bus_context_new): handle OOM copying bus type into
context struct
* dbus/dbus-message.c (dbus_message_iter_get_object_path): new function
(dbus_message_iter_get_object_path_array): new function (half
finished, disabled for the moment)
* glib/dbus-gproxy.c (dbus_gproxy_end_call): properly handle
DBUS_MESSAGE_TYPE_ERROR
* tools/dbus-launch.c (babysit): support DBUS_DEBUG_OUTPUT to
avoid redirecting stderr to /dev/null
(babysit): close stdin if not doing the "exit_with_session" thing
* dbus/dbus-sysdeps.c (_dbus_become_daemon): delete some leftover
debug code; change DBUS_DEBUG_OUTPUT to only enable stderr, not
stdout/stdin, so things don't get confused
* bus/system.conf.in: fix to allow replies, I modified .conf
instead of .conf.in again.
* tools/dbus-send.c (main): add --type argument, for now
supporting only method_call and signal types.

* bus/*.c: port over to object-instance API changes
* test/test-service.c: ditto
* dbus/dbus-message.c (dbus_message_create_header): allow #NULL
name, we will have to fix up the rest of the code to also handle
this
(dbus_message_new): generic message-creation call
(set_string_field): allow appending name field
* configure.in:
* bus/activation.c: (bus_activation_service_created),

* bus/session.conf.in:
* dbus/dbus-bus.c: (dbus_bus_acquire_service),
(dbus_bus_service_exists), (dbus_bus_activate_service):
* dbus/dbus-bus.h:
Add some convenience API which lets you activate a service, and did a
bunch of s/0/DBUS_TYPE_INVALID/ in calls to dbus_message_append_args()
and dbus_message_get_args()
Unbreak my code...

bus_transaction_send_error_reply
* bus/connection.c (bus_connection_get_groups): return an error
explaining the problem

users

* bus/bus.c (bus_context_check_security_policy): new
* bus/dispatch.c (send_service_nonexistent_error): delete this,
now we just set the DBusError and it gets converted to an error
reply.
* bus/connection.c (allow_user_function): enable code using actual
data from the config file
* bus/policy.c (list_allows_user): handle wildcard rules for
user/group connection perms
* dbus/dbus-spawn.c (_dbus_spawn_async_with_babysitter): move all

the connection if it's disconnected
* bus/activation.c (bus_activation_service_created): use new
transaction features to roll back removal of pending activation if

(_dbus_list_insert_after_link): new code to facilitate
services.c fixes

allowing us to put custom hooks in a transaction to be used for
cancelling said transaction

splits out part of bus_driver_handle_acquire_service() and fixes
a bug where we didn't remove the service doing the acquiring
from the secondary queue if we failed to remove the current owner
from the front of the queue.
* bus/dispatch.c: lots of fixes
* dbus/dbus-mainloop.c (_dbus_loop_dispatch): export
(_dbus_loop_iterate): remove old "quit if no callbacks" code,

first address.
* dbus/dbus-internals.c (_dbus_real_assert_not_reached): include
pid in assertion failures.
* dbus/dbus-mainloop.c (_dbus_loop_iterate): use static arrays up
to some fixed size of file descriptor array. Don't return TRUE

start with ':' and that the base service is created/deleted
as first and last things a connection does on the bus

the library, util functions that go in the lib and are also used
elsewhere, and util functions that are used in tests/daemon but
don't go in the lib.

here so it can be used in test binaries also
* bus/loop.c (bus_loop_iterate): fix the timeout code, using
magic from GLib
* dbus/dbus-spawn.c (_dbus_babysitter_unref): set sitter_pid
to -1 once we've reaped the babysitter
(_dbus_babysitter_handle_watch): do as much work as we can, not
just one go of it
* bus/activation.c: add code using DBusBabysitter so that we
handle it when a service fails to start up properly.
(bus_activation_service_created): don't remove the activation
entries as we go, just let them get removed when we free the pending
activation. Unref reply messages after sending them.
* Makefile.am (coverage-report.txt): add target "coverage-report.txt"

out of gcov files. Yes this is sort of silly.
* configure.in: define something in config.h and do an
AM_CONDITIONAL when gcov is enabled
* dbus/dbus-spawn.c, dbus/dbus-spawn.h: Change dbus_spawn to
return a "babysitter" object that is used to monitor the status of
the spawned process and reap it when required.

list of mechanisms, bug discovered by test suite enhancements
(putting system.conf and session.conf into suite)

test service that we'll activate as part of test suite. Doesn't
do anything yet.

setting NULL value, and use system malloc not dbus_malloc()
when we have unavoidable memleakage.
* dbus/dbus-bus.c (dbus_bus_get): fix bug where bus type of 0
didn't work, and support DBUS_BUS_ACTIVATION.
* bus/activation.c (child_setup): pass our well-known bus type to
the child
* bus/config-parser.c: support <type> to specify well-known type

"name" on get_args failure, should be done by get_args;
