* Throughout, align variant bodies according to the contained
type, rather than always to 8. Should save a fair bit of space in
message headers.
* dbus/dbus-marshal-validate.c (_dbus_validate_body_with_reason):
fix handling of case where p == end
* doc/TODO: remove the dbus_bool_t item and variant alignment items
* 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
* test/glib/test-profile.c: add with_bus mode to profile echoes
that go through the bus.
* test/glib/run-test.sh: add ability to run test-profile
* bus/dbus-daemon-1.1.in: fix to say that SIGHUP causes partial
config file reload.
The primary change here is to always write() once before adding
the write watch, which gives us about a 10% performance increase.
* dbus/dbus-transport-unix.c: a number of modifications to cope
with removing messages_pending
(check_write_watch): properly handle
DBUS_AUTH_STATE_WAITING_FOR_MEMORY; adapt to removal of
messages_pending stuff
(check_read_watch): properly handle WAITING_FOR_MEMORY and
AUTHENTICATED cases
(unix_handle_watch): after writing, see if the write watch can be
removed
(unix_do_iteration): assert that write_watch/read_watch are
non-NULL rather than testing that they aren't, since they
aren't allowed to be NULL. check_write_watch() at the end so
we add the watch if we did not finish writing (e.g. got EAGAIN)
* dbus/dbus-transport-protected.h: remove messages_pending call,
since it resulted in too much inefficient watch adding/removing;
instead we now require that the transport user does an iteration
after queueing outgoing messages, and after trying the first
write() we add a write watch if we got EAGAIN or exceeded our
max bytes to write per iteration setting
* dbus/dbus-string.c (_dbus_string_validate_signature): add this
function
* dbus/dbus-server-unix.c (unix_finalize): the socket name was
freed and then accessed, valgrind flagged this bug, fix it
* dbus/dbus-message.c: fix several bugs where HEADER_FIELD_LAST was taken
as the last valid field plus 1, where really it is equal to the
last valid field. Corrects some message corruption issues.
* dbus/dbus-mainloop.c: verbosity changes
* dbus/dbus-keyring.c (_dbus_keyring_new_homedir): handle OOM
instead of aborting in one of the test codepaths
* dbus/dbus-internals.c (_dbus_verbose_real): fix a bug that
caused not printing the pid ever again if a verbose was missing
the newline at the end
(_dbus_header_field_to_string): add HEADER_FIELD_SIGNATURE
* dbus/dbus-connection.c: verbosity changes;
(dbus_connection_has_messages_to_send): new function
(_dbus_connection_message_sent): no longer call transport->messages_pending
(_dbus_connection_send_preallocated_unlocked): do one iteration to
try to write() immediately, so we can avoid the write watch. This
is the core purpose of this patchset
(_dbus_connection_get_dispatch_status_unlocked): if disconnected,
dump the outgoing message queue, so nobody will get confused
trying to send them or thinking stuff is pending to be sent
* bus/test.c: verbosity changes
* bus/driver.c: verbosity/assertion changes
* bus/dispatch.c: a bunch of little tweaks to get it working again
because this patchset changes when/where you need to block.
* bus/selinux.h: Add bus_selinux_enabled.
* bus/selinux.c (bus_selinux_enabled): Implement it.
* bus/config-parser.c (struct include): Add
if_selinux_enabled member.
(start_busconfig_child): Parse if_selinux_enabled
attribute for include.
(bus_config_parser_content): Handle it.
* bus/session.conf.in, bus/system.conf.in: Add
inclusion of context mapping to default config files;
conditional on SELinux being enabled.
* doc/busconfig.dtd: Add to if_selinux_enabled to default DTD.
* test/data/invalid-config-files/badselinux-1.conf,
test/data/invalid-config-files/badselinux-2.conf:
Test files for bad syntax.
* bus/driver.c, bus/driver.h, bus/services.c: Use ServiceOwnerChanged
signal instead of ServiceCreated and ServiceDeleted.
* bus/dispatch.c: update testcase for the new signal.
* doc/busconfig.dtd: update the DTD for the at_console attribute.
* bus/driver.c (bus_driver_handle_hello): correctly handle Hello
messages after the first one (bug #1389).
* bus/dispatch.c (check_double_hello_message): add a test case for the
double hello message bug. (check_existent_service_activation): fix
check of spawning error.
* bus/dbus-daemon-1.1.in:
* test/data/valid-config-files/many-rules.conf: set the
max_match_rules_per_connection limt from the config file.
* doc/busconfig.dtd: update the DTD.
* bus/driver.c: remove some unused variables.
in the SELinux support.
* doc/busconfig.dtd: update DTD for SELinux support.

* doc/dbus-specification.xml: implement GetConnectionUnixUser
method of org.freedesktop.DBus interface.
* bus/dispatch.c: test case
* dbus/dbus-glib-error-enum.h: autogenerate the GError enum
codes from the dbus error names
* glib/dbus-glib.h: move to subdir dbus/ since it's included
as dbus/dbus-glib.h and that breakage is now visible due to
including dbus/dbus-glib.h in dbus-glib-lowlevel.h
* glib/dbus-glib.h: s/gproxy/g_proxy/
* dbus/dbus-shared.h: new header to hold stuff shared with
binding APIs
* dbus/dbus-protocol.h (DBUS_ERROR_*): move errors here rather
than dbus-errors.h
* glib/dbus-glib.h (dbus_set_g_error): move to
dbus-glib-lowlevel.h
* glib/dbus-glib.h: remove dbus/dbus.h from here; change a bunch
of stuff to enable this
* dbus/dbus-glib-lowlevel.h: put dbus/dbus.h here
* a bunch of other changes with the same basic "separate glib
bindings from dbus.h" theme
* dbus/dbus-auth.c: Rewrite auth protocol handling to use a state
machine approach. A state is implemented as a function that
handles incoming events as specified for that state.
* doc/dbus-specification.xml: Update auth protocol state machine
specification to match implementation. Remove some leftover
base64 examples.
version to the least-common-denominator between client and server?
Though in practice ever using this feature would be pretty tough,
since protocol probably modifies the API. But we could have it there
as a safety net.
Remove base64 encoding, replace with hex encoding. Original patch
from trow@ximian.com, added error handling.
* dbus/dbus-string.c (_dbus_string_base64_encode)
(_dbus_string_base64_decode): Remove.
(_dbus_string_hex_decode): Add end_return argument so we can
distinguish between OOM and invalid hex encoding.
(_dbus_string_test): Remove base64 tests and add test case for
invalid hex.
* dbus/dbus-keyring.c, dbus/dbus-auth-script.c, dbus/dbus-auth.c:
Replace base64 with hex.
* test/data/auth/invalid-hex-encoding.auth-script: New test case
for invalid hex encoded data in auth protocol.
* bus/driver.c (bus_driver_handle_get_service_owner):
implement a GetServiceOwner method.
* doc/dbus-specification.xml: document it.
* dbus/dbus-errors.h: add a 'ServiceHasNoOwner' error.
* glib/dbus-gproxy.c (dbus_gproxy_new_for_service_owner):
implement, using the bus GetServiceOwner method.
* test/glib/test-dbus-glib.c:
use dbus_gproxy_new_for_service_owner so that we can receive the
signal.
* bus/config-parser.c (struct BusConfigParser): Added
included_files field.
(seen_include): Added. Checks whether or not a file has already
been included by any parent BusConfigParser.
(bus_config_parser_new): Copy the parent's included_files.
(include_file): Track which files have been included, and fail on
circular inclusions.
(process_test_valid_subdir): Changed printf to report if we are
testing valid or invalid conf files.
(all_are_equiv): Changed printf to be a bit clearer about
what we are actually doing.

sources; run moc
* bus/bus.c (bus_context_check_security_policy): fix up assertion
* bus/connection.c (bus_transaction_send_from_driver): set the
destination to the connection's base service
hmm, make check is currently not passing.
* doc/dbus-specification.xml: add requirement that custom type
names follow the same rules as interface names.
* dbus/dbus-protocol.h: change some of the byte codes, to avoid
duplication and allow 'c' to be 'custom'; dict is now 'm' for
'map'
* doc/dbus-specification.xml: update type codes to match
dbus-protocol.h, using the ASCII byte values. Rename type NAMED to
CUSTOM. Add type OBJECT_PATH to the spec.
2003-10-17 Havoc Pennington <hp@redhat.com>

in base service names instead of '-'
* dbus/dbus-string.c (_dbus_string_get_byte): allow getting nul
byte at the end of the string
* dbus/dbus-internals.h (_DBUS_LIKELY, _DBUS_UNLIKELY): add
optimization macros since string validation seems to be a slow
point.
* doc/dbus-specification.xml: restrict valid
service/interface/member/error names. Add test suite code for the
name validation.

memory, return instead of g_error
* test/test-service.c (path_message_func): support emitting a
signal on request
* dbus/dbus-bus.c (init_connections_unlocked): only fill in
activation bus type if DBUS_BUS_ACTIVATION was set; default to
assuming the activation bus was the session bus so that services
started manually will still register.
(init_connections_unlocked): fix so that in OOM situation we get
the same semantics when retrying the function
* test/test-service.c (main): change to use path registration, to
test those codepaths; register with DBUS_BUS_ACTIVATION rather
than DBUS_BUS_SESSION
* 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
* glib/dbus-gproxy.c (gproxy_get_match_rule): match rules want
sender=foo not service=foo

DBUS_ACTIVATION_ADDRESS instead
* bus/activation.c: set DBUS_SESSION_BUS_ADDRESS,
DBUS_SYSTEM_BUS_ADDRESS if appropriate

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.
* bus/bus.c (bus_context_check_security_policy): revamp this to
work more sanely with new policy-based requested reply setup

sent to the bus driver, which was backward. How did this ever work
at all though? I think I'm missing something.
* dbus/dbus-message.c (decode_header_data): require error and
method return messages to have a reply serial field to be valid
(_dbus_message_loader_queue_messages): break up this function;
validate that reply serial and plain serial are nonzero;
clean up the OOM/error handling.
(get_uint_field): don't return -1 from this
(dbus_message_create_header): fix signed/unsigned bug
* bus/connection.c (bus_connections_expect_reply): save serial of
the incoming message, not reply serial
blocks any reply if one wasn't pending. Instead, it needs to
allow any reply if one was pending, and block otherwise.
Suggest changing the check_reply() call to just get a boolean
was_pending_reply value, pass that in to the policy
engine, and allow <allow>/<deny> elements to match based on
whether it was a pending reply.
* bus/connection.c: implement pending reply tracking using
BusExpireList
* bus/bus.c (bus_context_check_security_policy): verify that a
reply is pending in order to allow a reply to be sent. Deny
messages of unknown type.

* bus/bus.c (bus_context_get_max_replies_per_connection): new
(bus_context_get_reply_timeout): new
Added test code that 1) starts an actual bus daemon and 2) uses

more testing possible, but this is the basic framework.
* glib/dbus-gproxy.c (dbus_gproxy_manager_unregister): remove
empty proxy lists from the proxy list hash
* dbus/dbus-message.c (dbus_message_iter_get_args_valist): add a
couple of return_if_fail checks
* dbus/dbus-pending-call.c (_dbus_pending_call_new): use dbus_new0
to allocate, so everything is cleared to NULL as it should be.
* glib/dbus-gmain.c (dbus_connection_setup_with_g_main): pass
source as data to dbus_connection_set_timeout_functions() as the
timeout functions expected
* test/glib/run-test.sh: add a little script to start up a message
bus and run tests using it
* tools/dbus-launch.1: updates

that could never be reached.
* dbus/dbus-message.c (dbus_message_new_method_return)
(dbus_message_new_error, dbus_message_new_signal): set the
no-reply-expected flag on all these. Redundant, but may
as well be consistent.
* test/decode-gcov.c (function_solve_graph): make broken block
graph a nonfatal error since it seems to be broken. Need to debug
this.
* dbus/dbus-marshal.c (_dbus_type_is_valid): new function since we
can't just check type > INVALID < LAST anymore
* dbus/dbus-message.c (dbus_message_get_signature): new function
(dbus_message_has_signature): new function
(struct DBusMessage): add signature field (right now it isn't sent
over the wire, just generated on the fly)
(dbus_message_copy): copy the signature, and init strings to
proper length to avoid some reallocs
(dbus_message_iter_init_array_iterator): return void, since it
can't fail
(dbus_message_iter_init_dict_iterator): return void since it can't fail
(_dbus_message_loader_queue_messages): add silly temporary hack to
fill in message->signature on load
* dbus/dbus-protocol.h: change DBUS_TYPE_* values to be ASCII
characters, so they are relatively human-readable.
* dbus/dbus-message.c (_dbus_message_test): add more test
coverage, but #if 0 for now since they uncover a bug
not fixed yet; I think in re_align_field_recurse()
(re_align_field_recurse): add FIXME about broken assertion
* dbus/dbus-sysdeps.c (_dbus_sysdeps_test): add more test coverage
* bus/connection.c: share a couple code bits with expirelist.c
* bus/expirelist.h, bus/expirelist.c: implement a generic
expire-items-after-N-seconds facility, was going to share between
expiring connections and replies, decided not to use for expiring
connections for now.
* bus/connection.c: add tracking of expected replies
* COPYING: include AFL 2.0 (still need to change all the file headers)
