1 D-Bus 1.7.6 (UNRELEASED)
4 Build-time configuration changes:
6 • Directory change notification via dnotify on Linux is no longer
7 supported; it hadn't compiled successfully since 2010 in any case.
8 If you don't have inotify (Linux) or kqueue (*BSD), you will need
9 to send SIGHUP to the dbus-daemon when its configuration changes.
10 (fd.o #33001, Chengwei Yang)
12 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
13 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
14 with the Autotools build system. (fd.o #66142, Chengwei Yang)
18 • Be thread-safe by default on all platforms, even if
19 dbus_threads_init_default() has not been called. For compatibility with
20 older libdbus, library users should continue to call
21 dbus_threads_init_default(): it is harmless to do so.
22 (fd.o #54972, Simon McVittie)
26 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
27 (fd.o #65923, Chengwei Yang)
29 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
30 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
32 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
33 that was never va_start()ed (fd.o #66300, Chengwei Yang)
35 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
38 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
41 · Remove unavailable command-line options from 'dbus-daemon --help'
42 (fd.o #42441, Ralf Habacker)
45 · add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less confusing
46 conditionals (fd.o #66142, Chengwei Yang)
47 · improve verbose-mode output (fd.o #63047, Colin Walters)
48 · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker)
49 · fix various unused variables, unusual build configurations
50 etc. (fd.o #65712, #65990, #66005; Chengwei Yang)
52 D-Bus 1.7.4 (2013-06-13)
55 The “but is your thread-safety thread-safe?” release.
59 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
60 of service for system services. Vulnerability reported by Alexandru Cornea.
65 • The Windows version of libdbus now contains a C++ source file, used
66 to provide global initialization when the library is loaded.
67 gcc (mingw*) users should ensure that g++ is also installed.
69 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
70 and was never the recommended option) has been removed. Expat is now a
75 • It should now be safe to call dbus_threads_init_default() from any thread,
76 at any time. Authors of loadable modules and plugins that use libdbus
77 should consider doing so during initialization.
78 (fd.o #54972, Simon McVittie)
80 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
85 • In dbus-daemon, don't crash if a .service file starts with key=value
86 (fd.o #60853, Chengwei Yang)
89 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
90 on a platform not defining LOG_PERROR, such as Solaris or QNX.
91 This regressed in 1.7.0. (Simon)
92 · Fix an assertion failure if we try to activate systemd services before
93 systemd connects to the bus (fd.o #50199, Chengwei Yang)
94 · Avoid compiler warnings for ignoring the return from write()
98 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
99 so that Windows finds them (fd.o #59733, Ralf Habacker)
101 D-Bus 1.7.2 (2013-04-25)
104 The “only partially opaque” release.
106 Configuration changes:
108 • On non-QNX Unix platforms, the default limit on fds per message in the
109 session bus configuration has reduced from 4096 to 1024. The default
110 limit used on the system bus was already 1024. On QNX, both limits are
111 reduced further, to 128.
115 • D-Bus Specification 0.21
116 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
117 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
122 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
123 (i.e. before allocating the slot) rather than returning junk
124 (fd.o #63127, Dan Williams)
126 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
130 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
131 · Under systemd, log to syslog only, not stderr, avoiding duplication
132 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
133 · Under systemd, remove unnecessary dependency on syslog.socket
134 (fd.o #63531, Cristian Rodríguez)
135 · Include alloca.h for alloca() if available, fixing compilation on
136 Solaris 10 (fd.o #63071, Dagobert Michelsen)
137 · Allow use of systemd-logind without the rest of systemd
138 (fd.o #62585, Martin Pitt)
139 · When built with CMake, link to librt and use the right path for
140 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
141 · Reduce the default limit on number of fds per message to 128 under
142 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
145 · Do not claim that all bus clients have the dbus-daemon's credentials;
146 pick up local TCPv4 clients' credentials (process ID and security
147 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
150 D-Bus 1.7.0 (2013-02-22)
153 The "Disingenuous Assertions" release.
155 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
156 remains the recommended version for long-term-supported distributions
157 or the upcoming GNOME 3.8 release.
159 Build-time configuration changes:
161 • The --with-dbus-session-bus-default-address configure option is no longer
162 supported. Use the new --with-dbus-session-bus-connect-address and
163 --with-dbus-session-bus-listen-address options instead. On Windows, you
164 usually want them to have the same argument; on Unix, the defaults are
167 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
168 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
169 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
171 • cmake/cross-compile.sh has been removed. Instead, please use a
172 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
173 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
174 as documented in "info automake Cross-Compilation", and set
175 PKG_CONFIG_PATH appropriately.
179 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
180 • man2html is no longer used.
184 • D-Bus Specification 0.20
185 · actually say that /org/freedesktop/DBus is the object that
186 implements o.fd.DBus (fd.o #51865, Colin Walters)
187 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
188 · stop claiming that all basic types work just like INT32 (strings don't!)
190 • The "source code" for the man pages is now Docbook XML, eliminating
191 the outdated duplicate copies used when building with CMake.
192 (fd.o #59805; Ralf Habacker, Simon McVittie)
196 • In the activation helper, when compiled for tests, do not reset the system
197 bus address, fixing the regression tests. (fd.o #52202, Simon)
199 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
200 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
202 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,
205 • Under CMake, prefer xmlto over meinproc (fd.o #59733, Ralf Habacker)
207 • Stop duplicating CMake's own logic to find libexpat
208 (fd.o #59733, Ralf Habacker)
210 • Don't assume CMake host and build system are the same (fd.o #59733,
213 • Avoid deprecation warnings for GLib 2.35 (fd.o #59971, Simon McVittie)
216 · Check for functions in libpthread correctly, fixing compilation on
217 (at least) OpenBSD (fd.o #47239, Simon)
218 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
220 · Update sd-daemon.[ch] from systemd (fd.o #60681)
221 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
224 · The default session bus listening and connecting address is now
225 "autolaunch:", which makes D-Bus on Windows interoperate with itself
226 and GDBus "out of the box". Use the configure options and cmake variables
227 described above if you require a different autolaunch scope.
228 (fd.o #38201, Simon McVittie)
229 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
231 • Create session.d, system.d directories under CMake (fd.o #41319,
234 D-Bus 1.6.8 (2012-09-28)
237 The "Fix one thing, break another" release.
239 • Follow up to CVE-2012-3524: The additional hardening
240 work to use __secure_getenv() as a followup to bug #52202
241 broke certain configurations of gnome-keyring. Given
242 the difficulty of making this work without extensive
243 changes to gnome-keyring, use of __secure_getenv() is
246 D-Bus 1.6.6 (2012-09-28)
249 The "Clear the environment in your setuid binaries, please" release.
251 • CVE-2012-3524: Don't access environment variables (fd.o #52202)
252 Thanks to work and input from Colin Walters, Simon McVittie,
253 Geoffrey Thomas, and others.
255 · Fix compilation on Solaris (fd.o #53286, Jonathan Perkin)
256 · Work around interdependent headers on OpenBSD by including sys/types.h
257 before each use of sys/socket.h (fd.o #54418, Brad Smith)
259 D-Bus 1.6.4 (2012-07-18)
262 • Detect that users are "at the console" correctly when configured with
263 a non-default path such as --enable-console-auth-dir=/run/console
264 (fd.o #51521, Dave Reisner)
266 • Remove an incorrect assertion from DBusTransport (fd.o #51657,
269 • Make --enable-developer default to "no" (regression in 1.6.2;
270 fd.o #51657, Simon McVittie)
273 · Launch dbus-daemon correctly if its path contains a space
274 (fd.o #49450, Wolfgang Baron)
276 D-Bus 1.6.2 (2012-06-27)
279 The "Ice Cabbage" release.
281 • Change how we create /var/lib/dbus so it works under Automake >= 1.11.4
282 (fd.o #51406, Simon McVittie)
284 • Don't return from dbus_pending_call_set_notify with a lock held on OOM
285 (fd.o #51032, Simon McVittie)
287 • Disconnect "developer mode" (assertions, verbose mode etc.) from
288 Automake maintainer mode. D-Bus developers should now configure with
289 --enable-developer. Automake maintainer mode is now on by default;
290 distributions can disable it with --disable-maintainer-mode.
291 (fd.o #34671, Simon McVittie)
293 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
294 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
297 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
299 D-Bus 1.6.0 (2012-06-05)
302 The “soul of this machine has improved” release.
304 This version starts a new stable branch of D-Bus: only bug fixes will
305 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
307 Summary of changes since 1.4.x:

326 · DBusBasicValue, a union of every basic type
329 · removed an unsafe reimplementation of recursive mutexes
330 · dbus-daemon no longer busy-loops if it has far too many file descriptors
331 · dbus-daemon.exe --print-address works on Windows
332 · all the other bug fixes from 1.4.20
334 • Other major implementation changes
335 · on Linux, dbus-daemon uses epoll if supported, for better scalability
336 · dbus_threads_init() ignores its argument and behaves like
337 dbus_threads_init_default() instead
338 · removed the per-connection link cache, improving dbus-daemon performance
341 · optional Valgrind instrumentation (--with-valgrind)
342 · optional Stats interface on the dbus-daemon (--enable-stats)
343 · optionally abort whenever malloc() fails (--enable-embedded-tests
344 and export DBUS_MALLOC_CANNOT_FAIL=1)
346 Changes since 1.5.12:
348 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
349 spec-compliance (fd.o #48580, David Zeuthen)
351 • Don't use install(1) within the source/build trees, fixing the build as
352 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
354 • Add missing commas in some tcp and nonce-tcp addresses, and remove
355 an unused duplicate copy of the nonce-tcp transport in Windows builds
356 (fd.o #45896, Simon McVittie)
358 D-Bus 1.5.12 (2012-03-27)
361 The “Big Book of Science” release.
363 • Add public API to validate various string types:
364 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
365 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
366 (fd.o #39549, Simon McVittie)
368 • Turn DBusBasicValue into public API so bindings don't need to invent their
369 own "union of everything" type (fd.o #11191, Simon McVittie)
371 • Enumerate data files included in the build rather than using find(1)
372 (fd.o #33840, Simon McVittie)
374 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
375 in dbus-daemon (fd.o #46273, Alban Crequy)
378 · make dbus-daemon.exe --print-address (and --print-pid) work again
379 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
380 · fix duplicate case value when compiling against mingw-w64
381 (fd.o #47321, Andoni Morales Alastruey)
383 D-Bus 1.5.10 (2012-02-21)
386 The "fire in Delerium" release.
388 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
389 and SUSv2) is now required.
391 • D-Bus Specification 0.19:
392 · Formally define unique connection names and well-known bus names,
393 and document best practices for interface, bus, member and error names,
394 and object paths (fd.o #37095, Simon McVittie)
395 · Document the search path for session and system services on Unix, and
396 where they should be installed by build systems (fd.o #21620, fd.o #35306;
398 · Document the systemd transport (fd.o #35232, Lennart Poettering)
400 • Make dbus_threads_init() use the same built-in threading implementation
401 as dbus_threads_init_default(); the user-specified primitives that it
402 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
404 • Allow all configured auth mechanisms, not just one (fd.o #45106,
407 • Improve cmake build system (Ralf Habacker):
408 · simplify XML parser dependencies (fd.o #41027)
409 · generate build timestamp (fd.o #41029)
410 · only create batch files on Windows
411 · fix option and cache syntax
412 · add help-options target
413 · share dbus-arch-deps.h.in with autotools rather than having our
414 own version (fd.o #41033)
416 • Build tests successfully with older GLib, as found in e.g. Debian 6
417 (fd.o #41219, Simon McVittie)
419 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
421 • Build documentation correctly if man2html doesn't support filenames on
422 its command-line (fd.o #43875, Jack Nagel)
424 • Improve test coverage. To get even more coverage, run the tests with
425 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
427 • Reduce the size of the shared library by moving functionality only used
428 by dbus-daemon, tests etc. into their internal library and deleting
429 unused code (fd.o #34976, #39759; Simon McVittie)
431 • Add dbus-daemon --nopidfile option, overriding the configuration, for
432 setups where the default configuration must include <pidfile/> to avoid
433 breaking traditional init, but the pid file is in fact unnecessary; use
434 it under systemd to improve startup time a bit (fd.o #45520,
437 • Optionally (if configured --with-valgrind) add instrumentation to debug
438 libdbus and associated tools more meaningfully under Valgrind
439 (fd.o #37286, Simon McVittie)
441 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
443 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
445 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
446 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
447 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
450 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
454 · Replace our broken reimplementation of recursive mutexes, which has
455 been broken since 2006, with an ordinary pthreads recursive mutex
456 (fd.o #43744; Sigmund Augdal, Simon McVittie)
457 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
458 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
459 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
460 · When running under systemd, use it instead of ConsoleKit to check
461 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
462 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
463 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
464 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
465 (fd.o #41218, Simon McVittie)
466 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
467 helper doesn't obey environment variables to avoid privilege escalation
468 attacks, so make the system bus follow the same rules
469 (fd.o #21620, Simon McVittie)
472 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
473 Jesper Dam, Ralf Habacker)
474 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
477 D-Bus 1.5.8 (2011-09-21)
480 The "cross-metering" release.
482 In addition to dead code removal and refactoring, this release contains all
483 of the bugfixes from 1.4.16.
485 • Clean up dead code, and make more warnings fatal in development builds
486 (fd.o #39231, fd.o #41012; Simon McVittie)
488 • If full test coverage is requested via --enable-tests, strictly require
489 Python, pygobject and dbus-python, which are required by some tests; if not,
490 and Python is missing, skip those tests rather than failing
491 (fd.o #37847, Simon McVittie)
493 • When using cmake, provide the same version-info API in the installed headers
494 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
496 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
498 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
500 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
503 • Fix duplicates in authors list (Ralf Habacker)
505 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
506 (fd.o #39879, Chris Mayo)
508 • Fix a small memory leak, and a failure to report errors, when updating
509 a service file entry for activation (fd.o #39230, Simon McVittie)
512 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
513 Brian Cameron, Simon McVittie)
514 · On systems that use libcap-ng but not systemd, drop supplemental groups
515 when switching to the daemon user (Red Hat #726953, Steve Grubb)
516 · Make the cmake build work again on GNU platforms (fd.o #29228,
518 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
519 like Solaris (fd.o #40313, Dagobert Michelsen)
520 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
521 (fd.o #40235, Simon McVittie)
522 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
523 (fd.o #39987, Simon McVittie)
524 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
525 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
528 · Fix compilation on MSVC, which doesn't understand "inline" with its
529 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
530 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
531 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
533 D-Bus 1.5.6 (2011-07-29)
536 The "weird, gravy-like aftertaste" release.
538 In addition to new features and refactoring, this release contains all of the
539 bugfixes from 1.4.14.
541 Potentially incompatible (Bustle and similar debugging tools will need
542 changes to work as intended):
544 • Do not allow match rules to "eavesdrop" (receive messages intended for a
545 different recipient) by mistake: eavesdroppers must now opt-in to this
546 behaviour by putting "eavesdrop='true'" in the match rule, which will
547 not have any practical effect on buses where eavesdropping is not allowed
548 (fd.o #37890, Cosimo Alfarano)
552 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
553 Cosimo Alfarano, Simon McVittie)
554 · add the "eavesdrop" keyword to match rules
555 · define eavesdropping, unicast messages and broadcast messages
556 · stop claiming that match rules are needed to match unicast messages to you
557 · promote the type system to be a top-level section
559 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
560 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
561 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
563 • Consistently use atomic operations on everything that is ever manipulated
564 via atomic ops, as was done for changes to DBusConnection's refcount in
565 1.4.12 (fd.o #38005, Simon McVittie)
567 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
570 • Make "make check" in a clean tree work, by not running tests until
571 test data has been set up (fd.o #34405, Simon McVittie)
573 • The dbus-daemon no longer busy-loops if it has a very large number of file
574 descriptors (fd.o #23194, Simon McVittie)
576 • Refactor message flow through dispatching to avoid locking violations if
577 the bus daemon's message limit is hit; remove the per-connection link cache,
578 which was meant to improve performance, but now reduces it (fd.o #34393,
581 • Some cmake fixes (Ralf Habacker)
583 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
584 Simon McVittie, Lennart Poettering)
586 • Stop storing two extra byte order indicators in each D-Bus message
587 (fd.o #38287, Simon McVittie)
589 • Add an optional Stats interface which can be used to get statistics from
590 a running dbus-daemon if enabled at configure time with --enable-stats
591 (fd.o #34040, Simon McVittie)
593 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
595 • Documentation (fd.o #36156, Simon McVittie):
596 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
597 · install more documentation automatically, including man2html output
598 · put dbus.devhelp in the right place (it must go in ${htmldir})
601 · look for system services in /lib/dbus-1/system-services in addition to all
602 the other well-known locations; note that this should always be /lib,
603 even on platforms where shared libraries on the root FS would go in /lib64,
604 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
605 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
607 • Windows-specific (Ralf Habacker):
608 · fix use of a mutex for autolaunch server detection
609 · don't crash on malloc failure in _dbus_printf_string_upper_bound
611 D-Bus 1.5.4 (2011-06-10)
614 Security (local denial of service):
616 • Byte-swap foreign-endian messages correctly, preventing a long-standing
617 local DoS if foreign-endian messages are relayed through the dbus-daemon
618 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
619 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
623 • The constant to use for an infinite timeout now has a name,
624 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
625 which can be used for source compatibility with older versions of libdbus.
627 • If GLib and DBus-GLib are already installed, more tests will be built,
628 providing better coverage. The new tests can also be installed via
629 ./configure --enable-installed-tests
630 for system integration testing, if required. (fd.o #34570, Simon McVittie)
634 • Consistently use atomic operations for the DBusConnection's refcount,
635 fixing potential threading problems (fd.o #38005, Simon McVittie)
637 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
638 small (300KiB on x86-64) and it frequently doesn't work in unusual
639 toolchains. To optimize for minimum installed size, you should benchmark
640 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
641 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
643 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
644 (fd.o #35880, Timothy Redaelli)
646 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
647 when not using a DESTDIR (fd.o #37870, Simon McVittie)
649 • Windows-specific changes:
650 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
652 D-Bus 1.5.2 (2011-06-01)
655 The "Boar Hunter" release.
657 Notes for distributors:
659 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
660 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
661 toolchain supports it reliably, via something like:
663 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
665 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
669 • D-Bus Specification v0.17

674 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
675 • Allow --disable-gc-sections, in case your toolchain offers the
676 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
677 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
678 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
679 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
680 • Ensure that maintainers upload documentation with the right permissions
681 (fd.o #36130, Simon McVittie)
682 • Don't force users of libdbus to be linked against -lpthread, -lrt
683 (fd.o #32827, Simon McVittie)

686 • Log messages dropped due to quotas to syslog (fd.o #35358,
688 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
689 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
690 (fd.o #35228, Lennart Poettering)
691 • In the regression tests, don't report fds as "leaked" if they were open
692 on startup (fd.o #35173, Simon McVittie)
693 • Make dbus-monitor bail out if asked to monitor more than one bus,
694 rather than silently using the last one (fd.o #26548, Will Thompson)
695 • Clarify documentation (fd.o #35182, Simon McVittie)
696 • Clean up minor dead code and some incorrect error handling

710 · Add support for path_namespace and arg0namespace in match rules
711 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
712 · Make argNpath support object paths, not just object-path-like strings,
713 and document it better (fd.o #31818, Will Thompson)
714 • Let the bus daemon implement more than one interface (fd.o #33757,
716 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
718 • Require user intervention to compile with missing 64-bit support
719 (fd.o #35114, Simon McVittie)
720 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
721 • Raise UnknownObject instead of UnknownMethod for calls to methods on
722 paths that are not part of the object tree, and UnknownInterface for calls
723 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)

728 The "It's like the beginning of a lobster" release.
730 • Rename configure.in to configure.ac, and update it to modern conventions
731 (fd.o #32245; Javier Jardón, Simon McVittie)
732 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
734 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
735 --disable-x11-autolaunch configure option to prevent it altogether
736 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
737 • Install the documentation, and an index for Devhelp (fd.o #13495,
738 Debian #454142; Simon McVittie, Matthias Clasen)
739 • If checks are not disabled, check validity of string-like types and
740 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
741 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
742 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
743 • Break up a huge conditional in config-parser so gcov can produce coverage
744 data (fd.o #10887, Simon McVittie)
745 • List which parts of the Desktop Entry specification are applicable to
746 .service files (fd.o #19159, Sven Herzberg)
747 • Don't suppress service activation if two services have the same Exec=
748 (fd.o #35750, Colin Walters)
750 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
752 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
753 (fd.o #32805, Mark Brand)

761 which were mistakenly included in 1.4.4
763 D-Bus 1.4.4 (2010-02-17)
766 • Switch back to using even micro versions for stable releases; 1.4.1
767 should have been called 1.4.2, so skip that version number
768 • Don't leave bad file descriptors being watched when spawning processes,
769 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
770 also LP#656134, LP#680444, LP#713157)
771 • Check for MSG_NOSIGNAL correctly

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