* 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
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.

* bus/driver.c (create_unique_client_name): use "." as separator
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.
* dbus/dbus-string.c: limit service/interface/member/error names
to [0-9][A-Z][a-z]_
* dbus/dbus-connection.c (dbus_connection_dispatch): add missing
format arg to verbose spew
* glib/dbus-gproxy.c (dbus_gproxy_call_no_reply): if not out of
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
* 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.
* doc/dbus-specification.sgml: don't require header fields
to be 4-byte aligned and specify that fields should be
distinguished from padding by the fact that zero is not
a valid field name.
* doc/TODO: remove re-alignment item and add item to doc
the OBJECT_PATH type.
* dbus/dbus-message.c:
(HeaderField): rename the original member to value_offset
and introduce a name_offset member to keep track of where
the field actually begins.
(adjust_field_offsets): remove.
(append_int_field), (append_uint_field),
(append_string_field): don't align the start of the header
field to a 4-byte boundary.
(get_next_field): impl finding the next marhsalled field
after a given field.
(re_align_field_recurse): impl re-aligning a number of
already marshalled fields.
(delete_field): impl deleting a field of any type and
re-aligning any following fields.
(delete_int_or_uint_field), (delete_string_field): remove.
(set_int_field), (set_uint_field): no need to re-check
that we have the correct type for the field.
(set_string_field): ditto and impl re-aligning any
following fields.
(decode_header_data): update to take into account that
the fields aren't 4-byte aligned any more and the new
way to distinguish padding from header fields. Also,
don't exit when there is too much header padding.
(process_test_subdir): print the directory.
(_dbus_message_test): add test to make sure a following
field is re-aligned correctly after field deletion.
* dbus/dbus-string.[ch]:
(_dbus_string_insert_bytes): rename from insert_byte and
allow the insert of multiple bytes.
(_dbus_string_test): test inserting multiple bytes.
* dbus/dbus-marshal.c: (_dbus_marshal_set_string): add
warning note to docs about having to re-align any
marshalled values following the string.
* dbus/dbus-message-builder.c:
(append_string_field), (_dbus_message_data_load):
don't align the header field.

insert_byte change.

a dict in the unknown field.
* test/data/valid-messages/opposite-endian.message: fix test
to use proper type for rply field

* dbus/dbus-message.c (decode_header_data): validate field types,
and validate that named fields are valid names
(decode_name_field): consider messages in the

* dbus/dbus-string.c (_dbus_string_validate_name): new
* bus/config-parser.c (bus_config_parser_new): fix a memleak

the pid/gid/uid, just for paranoia.
* test/break-loader.c (randomly_do_n_things): find a byte
containing a type code, and randomly change it to a different
type code.
Fix some annoying DBusString API and fix all affected code.
* dbus/dbus-string.c (_dbus_string_init): get rid of annoying

optional value to "ALIGN" command which is what to fill the
alignment with.
