* 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
This is about it on what can be disabled/deleted from libdbus
easily, back below 150K anyhow. Deeper cuts are more work than
just turning the code off as I've done here.
* dbus/dbus-marshal-basic.c (_dbus_pack_int32): we don't need the
signed int convenience funcs
* dbus/dbus-internals.c (_dbus_verbose_real): omit when not in
verbose mode
* dbus/dbus-string-util.c, dbus/dbus-string.c: more breaking
things out of libdbus
* dbus/dbus-sysdeps.c, dbus/dbus-sysdeps-util.c: same
* dbus/dbus-hash.c: purge the TWO_STRINGS crap (well, make it
tests-enabled-only, though it should probably be deleted)
* dbus/dbus-message-util.c: same stuff
* dbus/dbus-auth-util.c: same stuff
* test/unused-code-gc.py: hacky script to find code that's used
only by the bus (not libdbus) or used only by tests or not used at
all. It has some false alarms, but looks like we can clean up a
lot of size from libdbus.
* dbus/dbus-sysdeps.c, dbus/dbus-sysdeps-utils.c,
dbus/Makefile.am: initially move 10K of binary size out of libdbus
* Add and fix docs according to Doxygen warnings throughout
source.
* dbus/dbus-marshal-recursive.c
(_dbus_type_reader_array_is_empty): change this to just call
array_reader_get_array_len() and make it static
* dbus/dbus-message.c (dbus_message_iter_get_element_type): rename
from get_array_type
(dbus_message_iter_init_append): rename from append_iter_init
* dbus/dbus-marshal-recursive.c
(_dbus_type_reader_get_element_type): rename from
_dbus_type_reader_get_array_type
* test/glib/test-profile.c (with_bus_server_filter): fix crash
* dbus/dbus-marshal-basic.c (_dbus_unpack_uint32): inline as macro
when DBUS_DISABLE_ASSERT
(_dbus_marshal_set_basic): be sure we align for the string length
* dbus/dbus-marshal-recursive.c (skip_one_complete_type): make
this look faster
* dbus/dbus-string.c (_dbus_string_get_const_data_len): add an
inline macro version
(_dbus_string_set_byte): provide inline macro version
* 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/decode-gcov.c: change to use .gcno and .gcda files, but the
file format has also changed and I haven't adapted to that yet
* Makefile.am: load .gcno files from latest gcc
* dbus/dbus-string.h (_dbus_string_get_byte): inline when asserts
are disabled
(_dbus_string_get_const_data): inline when asserts are disabled
* dbus/dbus-message.c: record the _dbus_current_generation of
creation so we can complain if dbus_shutdown() is used improperly.
Do this only if checks are enabled.
* dbus/dbus-connection.c: ditto
* 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.
* test/glib/test-profile.c: tweak a bit, add support for some
made-up minimal malloc overhead with plain sockets, since in
real life some sort of buffers are unavoidable thus we could
count them in the theoretical best case
* dbus/dbus-message.c (struct DBusMessage): put the locked bit and
the "char byte_order" next to each other to save 4 bytes
(dbus_message_new_empty_header): reduce preallocation, since the
message cache should achieve a similar effect
(dbus_message_cache_or_finalize, dbus_message_get_cached): add a
message cache that keeps a few DBusMessage around in a pool,
another 8% speedup or so.
* dbus/dbus-dataslot.c (_dbus_data_slot_list_clear): new function
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.
* test/glib/test-profile.c: modify to accept a plain_sockets
argument in which case it will bench plain sockets instead of
libdbus, for comparison purposes.
* test/glib/test-profile.c (N_CLIENT_THREADS): run multiple
threads for more time, so sysprof can get a grip on it.
* dbus/dbus-string.c (_dbus_string_validate_utf8): remove
pointless variable
* test/glib/test-profile.c: fix this thing up a bit
* dbus/dbus-message.c (dbus_message_new_empty_header): increase
preallocation sizes by a fair bit; not sure if this will be an
overall performance win or not, but it does reduce reallocs.
* dbus/dbus-string.c (set_length, reallocate_for_length): ignore
the test hack that forced constant realloc if asserts are
disabled, so we can profile sanely. Sprinkle in some
_DBUS_UNLIKELY() which are probably pointless, but before I
noticed the real performance problem I put them in.
(_dbus_string_validate_utf8): micro-optimize this thing a little
bit, though callgrind says it didn't help; then special-case
ascii, which did help a lot; then be sure we detect nul bytes as
invalid, which is a bugfix.
(align_length_then_lengthen): add some more _DBUS_UNLIKELY
superstition; use memset to nul the padding instead of a manual
loop.
(_dbus_string_get_length): inline this as a
macro; it showed up in the profile because it's used for loop
tests and so forth
* 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.
Patch from Nat Friedman <nat@novell.com>
* mono/Makefile.am: A number of small build fixes to allow "make
distcheck" to succeed.
* mono/example/Makefile.am: "make distcheck" fixes.
* mono/AssemblyInfo.cs.in: When signing the assembly, look for the
key in @srcdir@.
* test/Makefile.am: "make distcheck" fixes.
* 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.
SELinux support from Matthew Rickard <mjricka@epoch.ncsc.mil>
* bus/selinux.c, bus/selinux.h: new file encapsulating selinux
functionality
* configure.in: add --enable-selinux
* bus/policy.c (bus_policy_merge): add FIXME to a comment
* bus/main.c (main): initialize and shut down selinux
* bus/connection.c: store SELinux ID on each connection, to avoid
repeated getting of the string context and converting it into
an ID
* bus/bus.c (bus_context_get_policy): new accessor, though it
isn't used
(bus_context_check_security_policy): check whether the security
context of sender connection can send to the security context of
recipient connection
* bus/config-parser.c: add parsing for <selinux> and <associate>
* dbus/dbus-transport.c (_dbus_transport_get_unix_fd): to
implement dbus_connection_get_unix_fd()
* dbus/dbus-connection.c (dbus_connection_get_unix_fd): new
function, used by the selinux stuff
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.
* 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-message-builder.c (_dbus_message_data_load): append
random signature when using REQUIRED_FIELDS (this hack won't work
in the long term)
* dbus/dbus-message.c: change the signature to be a header field,
instead of message->signature special-case string. Incremental
step forward. Then we can fix up code to send the signature in the
message, then fix up code to validate said signature, then fix up
code to not put the typecodes inline, etc.
(load_one_message): don't make up the signature after the fact
(decode_header_data): require signature field for the known
message types
* dbus/dbus-marshal.c (_dbus_marshal_string_len): new
* dbus/dbus-protocol.h: add DBUS_HEADER_FIELD_SIGNATURE
* dbus/dbus-connection.h, dbus/dbus-connection.c: have object path
registration functions take the path argument as char* instead of
char**.
* dbus/dbus-marshal.h, dbus/dbus-marshal.c (_dbus_decompose_path):
split off the path decompostion part of
_dbus_demarshal_object_path. Some misc. fixes to silence compiler
warnings.
* glib/dbus-gobject.c, test/test-service.c: update accordingly.
* 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.
* glib/dbus-gidl.c (method_info_add_arg): keep args sorted with
"in" before "out"
* glib/dbus-gobject.c (dbus_type_to_string): move to dbus-gutils.c
* glib/dbus-glib-tool.c (main): set up to have a --self-test
option that runs the tests, and start filling in some code
including for starters just dumping the interfaces to stdout
* glib/Makefile.am (INCLUDES): define DBUS_LOCALEDIR
* test/data/valid-introspection-files/lots-of-types.xml: test of
an example introspection file
* glib/dbus-gparser.c (parser_check_doctype): doctype should be
"node" (I think...)
* test/glib/test-service-glib.c (main): remove unused variable
* glib/dbus-gidl.c (base_info_ref): fix a silly compiler warning
* dbus/dbus-auth.h (enum): remove AUTHENTICATED_WITH_UNUSED_BYTES
from the enum, no longer in use.
* dbus/dbus-sysdeps.h: include config.h so DBUS_VA_COPY actually
works right.
* dbus/dbus-message.c: add various _dbus_return_val_if_fail for
whether error_name passed in is a valid error name.
filter against auth->allowed_mechs; we only add allowed mechs in
record_mechanisms().
* dbus/dbus-auth-script.c (_dbus_auth_script_run): Add an
ALLOWED_MECHS to auth-script format so we can set the list of
allowed mechanisms.
* data/auth/client-out-of-mechanisms.auth-script: New test to
check client disconnects when it is out of mechanisms to try.
* dbus/dbus-auth.c (process_command): Remove check for lines
longer that 1 MB; we only buffer up maximum 16 kB.
* dbus/dbus-transport.c, dbus/dbus-transport-unix.c,
dbus/dbus-auth-script.c, dbus/dbus-auth.c, dbus/dbus-auth.h:
Remove auth state AUTHENTICATED_WITH_UNUSED_BYTES, instead always
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.
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.
(bus_config_parser_test): Test invalid configuration files.
* bus/config-parser.c (bus_config_parser_new): Added a 'parent'
argument. If non-null, the newly-constructed BusConfigParser will
be initialized with the parent's BusLimits instead of the default
values.
(include_file): When including a config file, pass in
the current parser as the parent and then copy the BusLimits
from the included BusConfigParser pack to the current parser.
(process_test_valid_subdir): Renamed from process_test_subdir.
(process_test_equiv_subdir): Added. Walks through a directory,
descending into each subdirectory and loading the config files
it finds there. If any subdirectory contains two config files
that don't produce identical BusConfigParser structs, fail.
For now, the BusConfigParser's BusPolicies are not compared.
(bus_config_parser_test): Call both process_test_valid_subdir and
process_test_equiv_subdir.
* bus/config-loader-libxml.c (bus_config_load): Take a parent
argument and pass it along to the call to bus_config_parser_new.
Also made a few small changes to allow this code to compile.
* bus/config-loader-expat.c (bus_config_load): Take a parent
argument and pass it along to the call to bus_config_parser_new.
* bus/bus.c (bus_context_new): Load the config file
with a NULL parent argument.
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>
* 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
* 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/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.
* test/decode-gcov.c: support gcc 3.3 also, though gcc 3.3 seems
to have a bug keeping it from outputting the .da files sometimes
(string_get_string): don't append garbage nul bytes to the string.
Added test code that 1) starts an actual bus daemon and 2) uses
DBusGProxy; fixed bugs that were revealed by the test. Lots
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
* tools/dbus-launch.c (main): add --config-file option
* tools/dbus-launch.c (main): remove confusing else if (runprog)
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.
