1 D-Bus 1.7.8 (UNRELEASED)
6 D-Bus 1.7.6 (2013-10-09)
9 The “CSI Shrewsbury” release.
11 Build-time configuration changes:
13 • Directory change notification via dnotify on Linux is no longer
14 supported; it hadn't compiled successfully since 2010 in any case.
15 If you don't have inotify (Linux) or kqueue (*BSD), you will need
16 to send SIGHUP to the dbus-daemon when its configuration changes.
17 (fd.o #33001, Chengwei Yang)
19 • Compiling with --disable-userdb-cache is no longer supported;
20 it didn't work since at least 2008, and would lead to an extremely
21 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
24 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
25 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
26 with the Autotools build system. (fd.o #66142, Chengwei Yang)
28 • --with-valgrind=auto enables Valgrind instrumentation if and only if
29 valgrind headers are available. The default is still --with-valgrind=no.
30 (fd.o #56925, Simon McVittie)
34 • Platforms with no 64-bit integer type are no longer supported.
35 (fd.o #65429, Simon McVittie)
37 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
39 • Full test coverage no longer requires dbus-glib, although the tests do not
40 exercise the shared library (only a static copy) if dbus-glib is missing.
41 (fd.o #68852, Simon McVittie)
45 • D-Bus Specification 0.22
46 · Document GetAdtAuditSessionData() and
47 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
48 · Fix example .service file (fd.o #66481, Chengwei Yang)
49 · Don't claim D-Bus is "low-latency" (lower than what?), just
50 give factual statements about it supporting async use
51 (fd.o #65141, Justin Lee)
52 · Document the contents of .service files, and the fact that
53 system services' filenames are constrained
54 (fd.o #66608; Simon McVittie, Chengwei Yang)
56 • Be thread-safe by default on all platforms, even if
57 dbus_threads_init_default() has not been called. For compatibility with
58 older libdbus, library users should continue to call
59 dbus_threads_init_default(): it is harmless to do so.
60 (fd.o #54972, Simon McVittie)
62 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
64 • New API: dbus_setenv(), a simple wrapper around setenv().
65 Note that this is not thread-safe. (fd.o #39196, Simon)
67 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
68 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
69 (connect to a given bus, like dbus-monitor --address=ADDRESS).
70 dbus-send --address still exists for backwards compatibility,
71 but is no longer documented. (fd.o #48816, Andrey Mazo)
74 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
79 • Avoid an infinite busy-loop if a signal interrupts waitpid()
80 (fd.o #68945, Simon McVittie)
82 • Clean up memory for parent nodes when objects are unexported
83 (fd.o #60176, Thomas Fitzsimmons)
85 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
86 documented. Previously, it assumed its second parameter was TRUE.
87 (fd.o #69165, Chengwei Yang)
89 • Escape addresses containing non-ASCII characters correctly
90 (fd.o #53499, Chengwei Yang)
92 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
94 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
95 (fd.o #65923, Chengwei Yang)
97 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
98 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
100 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
101 that was never va_start()ed (fd.o #66300, Chengwei Yang)
103 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
105 • fix a regression test on platforms with strict alignment (fd.o #67279,
108 • Avoid calling function parameters "interface" since certain Windows headers
109 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
111 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
113 • Various thread-safety improvements to static variables (fd.o #68610,
116 • Make "make -j check" work (fd.o #68852, Simon McVittie)
118 • Fix a NULL pointer dereference on an unlikely error path
119 (fd.o #69327, Sviatoslav Chagaev)
121 • Improve valgrind memory pool tracking (fd.o #69326,
124 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
127 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
128 (fd.o #66107, Chengwei Yang)
131 · If accept4() fails with EINVAL, as it can on older Linux kernels
132 with newer glibc, try accept() instead of going into a busy-loop.
133 (fd.o #69026, Chengwei Yang)
134 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
135 for instance on Hurd or older Linux with a new glibc, try without
136 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)
137 · Fix a file descriptor leak on an error code path.
138 (fd.o #69182, Sviatoslav Chagaev)
139 · dbus-run-session: clear some unwanted environment variables
141 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
142 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
143 · Use dbus-launch from the builddir for testing, not the installed copy
144 (fd.o #37849, Chengwei Yang)
145 · Fix compilation if writev() is unavailable (fd.o #69409,
147 · Remove broken support for LOCAL_CREDS credentials passing, and
148 document where each credential-passing scheme is used (fd.o #60340,
150 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
151 (fd.o #35881, #69787; Chengwei Yang)
152 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)
153 · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon)
154 · Improve error reporting from the setuid activation helper (fd.o #66728,
158 · Remove unavailable command-line options from 'dbus-daemon --help'
159 (fd.o #42441, Ralf Habacker)

161 Windows XP via the undocumented AllocateAndGetTcpExTableFromStack
162 function (fd.o #66060, Ralf Habacker)
163 · Fix insufficient dependency-tracking (fd.o #68505, Simon McVittie)
164 · Don't include wspiapi.h, fixing a compiler warning (fd.o #68852,
168 · add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less confusing
169 conditionals (fd.o #66142, Chengwei Yang)

176 D-Bus 1.7.4 (2013-06-13)
179 The “but is your thread-safety thread-safe?” release.
183 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
184 of service for system services. Vulnerability reported by Alexandru Cornea.
189 • The Windows version of libdbus now contains a C++ source file, used
190 to provide global initialization when the library is loaded.
191 gcc (mingw*) users should ensure that g++ is also installed.
193 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
194 and was never the recommended option) has been removed. Expat is now a
199 • It should now be safe to call dbus_threads_init_default() from any thread,
200 at any time. Authors of loadable modules and plugins that use libdbus
201 should consider doing so during initialization.
202 (fd.o #54972, Simon McVittie)
204 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
208 · dbus-run-session: experimental new tool to start a temporary D-Bus
209 session, e.g. for regression tests or a text console, replacing
210 certain uses of dbus-launch which weren't really correct
215 • In dbus-daemon, don't crash if a .service file starts with key=value
216 (fd.o #60853, Chengwei Yang)
219 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
220 on a platform not defining LOG_PERROR, such as Solaris or QNX.
221 This regressed in 1.7.0. (Simon)
222 · Fix an assertion failure if we try to activate systemd services before
223 systemd connects to the bus (fd.o #50199, Chengwei Yang)
224 · Avoid compiler warnings for ignoring the return from write()
228 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
229 so that Windows finds them (fd.o #59733, Ralf Habacker)
231 D-Bus 1.7.2 (2013-04-25)
234 The “only partially opaque” release.
236 Configuration changes:
238 • On non-QNX Unix platforms, the default limit on fds per message in the
239 session bus configuration has reduced from 4096 to 1024. The default
240 limit used on the system bus was already 1024. On QNX, both limits are
241 reduced further, to 128.
245 • D-Bus Specification 0.21
246 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
247 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
252 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
253 (i.e. before allocating the slot) rather than returning junk
254 (fd.o #63127, Dan Williams)
256 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
260 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
261 · Under systemd, log to syslog only, not stderr, avoiding duplication
262 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
263 · Under systemd, remove unnecessary dependency on syslog.socket
264 (fd.o #63531, Cristian Rodríguez)
265 · Include alloca.h for alloca() if available, fixing compilation on
266 Solaris 10 (fd.o #63071, Dagobert Michelsen)
267 · Allow use of systemd-logind without the rest of systemd
268 (fd.o #62585, Martin Pitt)
269 · When built with CMake, link to librt and use the right path for
270 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
271 · Reduce the default limit on number of fds per message to 128 under
272 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
275 · Do not claim that all bus clients have the dbus-daemon's credentials;
276 pick up local TCPv4 clients' credentials (process ID and security
277 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
280 D-Bus 1.7.0 (2013-02-22)
283 The "Disingenuous Assertions" release.
285 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
286 remains the recommended version for long-term-supported distributions
287 or the upcoming GNOME 3.8 release.
289 Build-time configuration changes:
291 • The --with-dbus-session-bus-default-address configure option is no longer
292 supported. Use the new --with-dbus-session-bus-connect-address and
293 --with-dbus-session-bus-listen-address options instead. On Windows, you
294 usually want them to have the same argument; on Unix, the defaults are
297 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
298 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
299 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
301 • cmake/cross-compile.sh has been removed. Instead, please use a
302 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
303 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
304 as documented in "info automake Cross-Compilation", and set
305 PKG_CONFIG_PATH appropriately.
309 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
310 • man2html is no longer used.
314 • D-Bus Specification 0.20
315 · actually say that /org/freedesktop/DBus is the object that
316 implements o.fd.DBus (fd.o #51865, Colin Walters)
317 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
318 · stop claiming that all basic types work just like INT32 (strings don't!)
320 • The "source code" for the man pages is now Docbook XML, eliminating
321 the outdated duplicate copies used when building with CMake.
322 (fd.o #59805; Ralf Habacker, Simon McVittie)
326 • In the activation helper, when compiled for tests, do not reset the system
327 bus address, fixing the regression tests. (fd.o #52202, Simon)
329 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
330 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
332 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

338 (fd.o #59733, Ralf Habacker)
340 • Don't assume CMake host and build system are the same (fd.o #59733,
343 • Avoid deprecation warnings for GLib 2.35 (fd.o #59971, Simon McVittie)

347 (at least) OpenBSD (fd.o #47239, Simon)
348 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
350 · Update sd-daemon.[ch] from systemd (fd.o #60681)
351 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
354 · The default session bus listening and connecting address is now
355 "autolaunch:", which makes D-Bus on Windows interoperate with itself
356 and GDBus "out of the box". Use the configure options and cmake variables
357 described above if you require a different autolaunch scope.
358 (fd.o #38201, Simon McVittie)
359 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
361 • Create session.d, system.d directories under CMake (fd.o #41319,
364 D-Bus 1.6.8 (2012-09-28)
367 The "Fix one thing, break another" release.
369 • Follow up to CVE-2012-3524: The additional hardening
370 work to use __secure_getenv() as a followup to bug #52202
371 broke certain configurations of gnome-keyring. Given
372 the difficulty of making this work without extensive
373 changes to gnome-keyring, use of __secure_getenv() is
376 D-Bus 1.6.6 (2012-09-28)
379 The "Clear the environment in your setuid binaries, please" release.
381 • CVE-2012-3524: Don't access environment variables (fd.o #52202)
382 Thanks to work and input from Colin Walters, Simon McVittie,
383 Geoffrey Thomas, and others.
385 · Fix compilation on Solaris (fd.o #53286, Jonathan Perkin)
386 · Work around interdependent headers on OpenBSD by including sys/types.h
387 before each use of sys/socket.h (fd.o #54418, Brad Smith)
389 D-Bus 1.6.4 (2012-07-18)
392 • Detect that users are "at the console" correctly when configured with
393 a non-default path such as --enable-console-auth-dir=/run/console
394 (fd.o #51521, Dave Reisner)
396 • Remove an incorrect assertion from DBusTransport (fd.o #51657,

400 fd.o #51657, Simon McVittie)
403 · Launch dbus-daemon correctly if its path contains a space
404 (fd.o #49450, Wolfgang Baron)
406 D-Bus 1.6.2 (2012-06-27)
409 The "Ice Cabbage" release.
411 • Change how we create /var/lib/dbus so it works under Automake >= 1.11.4
412 (fd.o #51406, Simon McVittie)
414 • Don't return from dbus_pending_call_set_notify with a lock held on OOM
415 (fd.o #51032, Simon McVittie)
417 • Disconnect "developer mode" (assertions, verbose mode etc.) from
418 Automake maintainer mode. D-Bus developers should now configure with
419 --enable-developer. Automake maintainer mode is now on by default;
420 distributions can disable it with --disable-maintainer-mode.
421 (fd.o #34671, Simon McVittie)
423 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
424 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)

496 (fd.o #39549, Simon McVittie)
498 • Turn DBusBasicValue into public API so bindings don't need to invent their
499 own "union of everything" type (fd.o #11191, Simon McVittie)
501 • Enumerate data files included in the build rather than using find(1)
502 (fd.o #33840, Simon McVittie)
504 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
505 in dbus-daemon (fd.o #46273, Alban Crequy)

516 The "fire in Delerium" release.
518 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
519 and SUSv2) is now required.
521 • D-Bus Specification 0.19:
522 · Formally define unique connection names and well-known bus names,
523 and document best practices for interface, bus, member and error names,
524 and object paths (fd.o #37095, Simon McVittie)
525 · Document the search path for session and system services on Unix, and
526 where they should be installed by build systems (fd.o #21620, fd.o #35306;
528 · Document the systemd transport (fd.o #35232, Lennart Poettering)
530 • Make dbus_threads_init() use the same built-in threading implementation

532 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
534 • Allow all configured auth mechanisms, not just one (fd.o #45106,
537 • Improve cmake build system (Ralf Habacker):
538 · simplify XML parser dependencies (fd.o #41027)
539 · generate build timestamp (fd.o #41029)
540 · only create batch files on Windows
541 · fix option and cache syntax
542 · add help-options target
543 · share dbus-arch-deps.h.in with autotools rather than having our
544 own version (fd.o #41033)

551 • Build documentation correctly if man2html doesn't support filenames on
552 its command-line (fd.o #43875, Jack Nagel)
554 • Improve test coverage. To get even more coverage, run the tests with
555 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
557 • Reduce the size of the shared library by moving functionality only used
558 by dbus-daemon, tests etc. into their internal library and deleting
559 unused code (fd.o #34976, #39759; Simon McVittie)
561 • Add dbus-daemon --nopidfile option, overriding the configuration, for
562 setups where the default configuration must include <pidfile/> to avoid
563 breaking traditional init, but the pid file is in fact unnecessary; use
564 it under systemd to improve startup time a bit (fd.o #45520,
567 • Optionally (if configured --with-valgrind) add instrumentation to debug
568 libdbus and associated tools more meaningfully under Valgrind

575 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
576 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
577 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
580 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
584 · Replace our broken reimplementation of recursive mutexes, which has
585 been broken since 2006, with an ordinary pthreads recursive mutex
586 (fd.o #43744; Sigmund Augdal, Simon McVittie)
587 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
588 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
589 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
590 · When running under systemd, use it instead of ConsoleKit to check
591 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
592 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
593 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
594 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
595 (fd.o #41218, Simon McVittie)
596 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
597 helper doesn't obey environment variables to avoid privilege escalation
598 attacks, so make the system bus follow the same rules
599 (fd.o #21620, Simon McVittie)
602 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
603 Jesper Dam, Ralf Habacker)
604 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
607 D-Bus 1.5.8 (2011-09-21)
610 The "cross-metering" release.
612 In addition to dead code removal and refactoring, this release contains all
613 of the bugfixes from 1.4.16.
615 • Clean up dead code, and make more warnings fatal in development builds
616 (fd.o #39231, fd.o #41012; Simon McVittie)
618 • If full test coverage is requested via --enable-tests, strictly require
619 Python, pygobject and dbus-python, which are required by some tests; if not,
620 and Python is missing, skip those tests rather than failing
621 (fd.o #37847, Simon McVittie)
623 • When using cmake, provide the same version-info API in the installed headers
624 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
626 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
628 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
630 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
633 • Fix duplicates in authors list (Ralf Habacker)
635 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
636 (fd.o #39879, Chris Mayo)
638 • Fix a small memory leak, and a failure to report errors, when updating
639 a service file entry for activation (fd.o #39230, Simon McVittie)
642 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
643 Brian Cameron, Simon McVittie)
644 · On systems that use libcap-ng but not systemd, drop supplemental groups
645 when switching to the daemon user (Red Hat #726953, Steve Grubb)
646 · Make the cmake build work again on GNU platforms (fd.o #29228,
648 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
649 like Solaris (fd.o #40313, Dagobert Michelsen)
650 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
651 (fd.o #40235, Simon McVittie)
652 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
653 (fd.o #39987, Simon McVittie)
654 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
655 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
658 · Fix compilation on MSVC, which doesn't understand "inline" with its
659 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
660 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
661 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
663 D-Bus 1.5.6 (2011-07-29)
666 The "weird, gravy-like aftertaste" release.
668 In addition to new features and refactoring, this release contains all of the
669 bugfixes from 1.4.14.
671 Potentially incompatible (Bustle and similar debugging tools will need
672 changes to work as intended):
674 • Do not allow match rules to "eavesdrop" (receive messages intended for a
675 different recipient) by mistake: eavesdroppers must now opt-in to this
676 behaviour by putting "eavesdrop='true'" in the match rule, which will
677 not have any practical effect on buses where eavesdropping is not allowed
678 (fd.o #37890, Cosimo Alfarano)
682 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
683 Cosimo Alfarano, Simon McVittie)
684 · add the "eavesdrop" keyword to match rules
685 · define eavesdropping, unicast messages and broadcast messages
686 · stop claiming that match rules are needed to match unicast messages to you
687 · promote the type system to be a top-level section
689 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
690 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
691 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
693 • Consistently use atomic operations on everything that is ever manipulated
694 via atomic ops, as was done for changes to DBusConnection's refcount in
695 1.4.12 (fd.o #38005, Simon McVittie)
697 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
700 • Make "make check" in a clean tree work, by not running tests until
701 test data has been set up (fd.o #34405, Simon McVittie)
703 • The dbus-daemon no longer busy-loops if it has a very large number of file
704 descriptors (fd.o #23194, Simon McVittie)
706 • Refactor message flow through dispatching to avoid locking violations if
707 the bus daemon's message limit is hit; remove the per-connection link cache,
708 which was meant to improve performance, but now reduces it (fd.o #34393,
711 • Some cmake fixes (Ralf Habacker)
713 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
714 Simon McVittie, Lennart Poettering)
716 • Stop storing two extra byte order indicators in each D-Bus message
717 (fd.o #38287, Simon McVittie)
719 • Add an optional Stats interface which can be used to get statistics from
720 a running dbus-daemon if enabled at configure time with --enable-stats
721 (fd.o #34040, Simon McVittie)
723 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
725 • Documentation (fd.o #36156, Simon McVittie):
726 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
727 · install more documentation automatically, including man2html output
728 · put dbus.devhelp in the right place (it must go in ${htmldir})
731 · look for system services in /lib/dbus-1/system-services in addition to all
732 the other well-known locations; note that this should always be /lib,
733 even on platforms where shared libraries on the root FS would go in /lib64,
734 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
735 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
737 • Windows-specific (Ralf Habacker):
738 · fix use of a mutex for autolaunch server detection
739 · don't crash on malloc failure in _dbus_printf_string_upper_bound
741 D-Bus 1.5.4 (2011-06-10)
744 Security (local denial of service):
746 • Byte-swap foreign-endian messages correctly, preventing a long-standing
747 local DoS if foreign-endian messages are relayed through the dbus-daemon
748 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
749 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
753 • The constant to use for an infinite timeout now has a name,
754 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
755 which can be used for source compatibility with older versions of libdbus.
757 • If GLib and DBus-GLib are already installed, more tests will be built,
758 providing better coverage. The new tests can also be installed via
759 ./configure --enable-installed-tests
760 for system integration testing, if required. (fd.o #34570, Simon McVittie)
764 • Consistently use atomic operations for the DBusConnection's refcount,
765 fixing potential threading problems (fd.o #38005, Simon McVittie)
767 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
768 small (300KiB on x86-64) and it frequently doesn't work in unusual
769 toolchains. To optimize for minimum installed size, you should benchmark
770 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
771 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
773 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
774 (fd.o #35880, Timothy Redaelli)
776 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
777 when not using a DESTDIR (fd.o #37870, Simon McVittie)
779 • Windows-specific changes:
780 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
782 D-Bus 1.5.2 (2011-06-01)
785 The "Boar Hunter" release.
787 Notes for distributors:
789 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
790 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
791 toolchain supports it reliably, via something like:
793 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
795 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
799 • D-Bus Specification v0.17
800 · Reserve the extra characters used in signatures by GVariant
801 (fd.o #34529, Simon McVittie)
802 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
803 • Don't force -fPIE: distributions and libtool know better than we do whether
804 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
805 • Allow --disable-gc-sections, in case your toolchain offers the
806 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
807 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
808 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
809 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
810 • Ensure that maintainers upload documentation with the right permissions
811 (fd.o #36130, Simon McVittie)
812 • Don't force users of libdbus to be linked against -lpthread, -lrt
813 (fd.o #32827, Simon McVittie)
814 • Log system-bus activation information to syslog (fd.o #35705,
816 • Log messages dropped due to quotas to syslog (fd.o #35358,
818 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
819 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
820 (fd.o #35228, Lennart Poettering)
821 • In the regression tests, don't report fds as "leaked" if they were open
822 on startup (fd.o #35173, Simon McVittie)
823 • Make dbus-monitor bail out if asked to monitor more than one bus,
824 rather than silently using the last one (fd.o #26548, Will Thompson)
825 • Clarify documentation (fd.o #35182, Simon McVittie)
826 • Clean up minor dead code and some incorrect error handling
827 (fd.o #33128, fd.o #29881; Simon McVittie)
828 • Check that compiler options are supported before using them (fd.o #19681,
831 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)

836 The "you never know when you need to tow something from your giant
837 flying shark" release.
839 • D-Bus Specification v0.16
840 · Add support for path_namespace and arg0namespace in match rules
841 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
842 · Make argNpath support object paths, not just object-path-like strings,
843 and document it better (fd.o #31818, Will Thompson)
844 • Let the bus daemon implement more than one interface (fd.o #33757,
846 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
848 • Require user intervention to compile with missing 64-bit support
849 (fd.o #35114, Simon McVittie)
850 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
851 • Raise UnknownObject instead of UnknownMethod for calls to methods on
852 paths that are not part of the object tree, and UnknownInterface for calls
853 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
855 D-Bus 1.4.8 (2011-04-08)
858 The "It's like the beginning of a lobster" release.
860 • Rename configure.in to configure.ac, and update it to modern conventions
861 (fd.o #32245; Javier Jardón, Simon McVittie)
862 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
864 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
865 --disable-x11-autolaunch configure option to prevent it altogether
866 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
867 • Install the documentation, and an index for Devhelp (fd.o #13495,
868 Debian #454142; Simon McVittie, Matthias Clasen)
869 • If checks are not disabled, check validity of string-like types and
870 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
871 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
872 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
873 • Break up a huge conditional in config-parser so gcov can produce coverage
874 data (fd.o #10887, Simon McVittie)
875 • List which parts of the Desktop Entry specification are applicable to
876 .service files (fd.o #19159, Sven Herzberg)
877 • Don't suppress service activation if two services have the same Exec=
878 (fd.o #35750, Colin Walters)
880 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
882 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
883 (fd.o #32805, Mark Brand)
885 D-Bus 1.4.6 (2010-02-17)
888 The "1, 2, miss a few, 99, 100" release.
890 • Remove unfinished changes intended to support GTest-based tests,
891 which were mistakenly included in 1.4.4
893 D-Bus 1.4.4 (2010-02-17)
896 • Switch back to using even micro versions for stable releases; 1.4.1
897 should have been called 1.4.2, so skip that version number
898 • Don't leave bad file descriptors being watched when spawning processes,
899 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
900 also LP#656134, LP#680444, LP#713157)
901 • Check for MSG_NOSIGNAL correctly

931 D-Bus 1.4.1 (20 December 2010)
934 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
935 crash the bus. The existing restriction to 64-levels of nesting previously
936 only applied to the static type signature; now it also applies to dynamic
937 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
939 • OS X portability fixes, including launchd support.
940 • Windows autolaunch improvements.
