1 D-Bus 1.8.2 (2014-04-30)
4 The “nobody wants red” release.
8 • in the CMake build system, add some hints for Linux users cross-compiling
9 Windows D-Bus binaries to be able to run tests under Wine
10 (fd.o #41252, Ralf Habacker)
12 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
16 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
17 to /var/lib/dbus/machine-id instead of generating an entirely new ID
18 (fd.o #77941, Simon McVittie)
20 • if dbus-launch receives an X error very quickly, do not kill
21 unrelated processes (fd.o #74698, Роман Донченко)
23 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
24 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
26 • cope with \r\n newlines in regression tests, since on Windows,
27 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
29 D-Bus 1.8.0 (2014-01-20)
32 The “Wolverine distrusts my printer” release.
34 This starts a new stable branch. The 1.6.x branch is now considered to be
35 outdated, and will only receive fixes for serious bugs such as security
36 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
37 are unlikely to get any more releases, but if distributors still need to
38 support them, please share security patches via upstream.
40 Summary of changes since 1.6.x:
42 • libdbus always behaves as if dbus_threads_init_default() had been called
43 (thread-safety by default)
44 • new dbus-run-session tool, replacing certain misuses of dbus-launch
45 • dbus-monitor can talk to outdated versions of dbus-daemon again
46 • new org.freedesktop.DBus.GetConnectionCredentials method
47 • GetConnectionUnixProcessID also works correctly on Windows, returning
48 the Windows process ID
49 • GetConnectionWindowsSID returns the correct SID on Windows
50 • expat is required, libxml2 can no longer be used as a substitute
51 • the userDB cache is required, and cannot be disabled
52 • a 64-bit integer type (either int, long, long long or _int64) is required
53 • better systemd-journald integration on Linux
54 • fixed long-standing fd and array leaks when failing to parse a message
55 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
56 when using certain object-path allocation patterns, notably in Avahi
57 • better defaults for Windows support
58 • better CMake support
59 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
60 • the source language for the man pages is now Docbook XML
62 Enhancements since 1.7.10:
64 • Enhance the CMake build system to check for GLib and compile/run
65 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
69 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
72 • fix compilation of systemd journal support on older systemd versions where
73 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
75 • fix compilation on older MSVC versions by including stdlib.h
76 (fd.o #73455, Ralf Habacker)
78 • Allow <allow_anonymous/> to appear in an included configuration file
79 (fd.o #73475, Matt Hoosier)
81 Test behaviour changes since 1.7.10:
83 • If the tests crash with an assertion failure, they no longer default to
84 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
85 environment if you want the old behaviour.
87 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
88 can be run with an external dbus-daemon by setting
89 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
90 an unusually-configured dbus-daemon are skipped.
92 D-Bus 1.7.10 (2014-01-06)
95 The “weighted companion cube” release.
97 This is a release candidate for D-Bus 1.8.
99 D-Bus Specification 0.23:
101 • don't require messages with no INTERFACE to be dispatched
102 (fd.o #68597, Simon McVittie)
104 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
107 • define "listenable" and "connectable" addresses, and discuss
108 the difference (fd.o #61303, Simon McVittie)
112 • support printing Unix file descriptors in dbus-send, dbus-monitor
113 (fd.o #70592, Robert Ancell)
115 • don't install systemd units if --disable-systemd is given
116 (fd.o #71818, Chengwei Yang)
120 • don't leak memory on out-of-memory while listing activatable or
121 active services (fd.o #71526, Radoslaw Pajak)
123 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
125 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
127 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
128 and DBUS__SEND_MSG are numerically equal to their values in the
129 reference policy (fd.o #88719, osmond sun)
131 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
132 (fd.o #71366, Matt Fischer)
134 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
135 winsock2.h (fd.o #71405, Matt Fischer)
137 • do not return failure from _dbus_read_nonce() with no error set,
138 preventing a potential crash (fd.o #72298, Chengwei Yang)
140 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
141 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
143 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
144 which doesn't do anything anyway on at least Linux and FreeBSD
145 (fd.o #69492, Simon McVittie)
147 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
148 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
149 for credentials more correctly (fd.o #69492, Simon McVittie)
151 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
152 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
155 • refresh cached policy rules for existing connections when bus
156 configuration changes (fd.o #39463, Chengwei Yang)
158 D-Bus 1.7.8 (2013-11-01)
161 The “extreme hills” release.
165 • If systemd support is enabled, libsystemd-journal is now required.
169 • When activating a non-systemd service under systemd, annotate its
170 stdout/stderr with its bus name in the Journal. Known limitation:
171 because the socket is opened before forking, the process will still be
172 logged as if it had dbus-daemon's process ID and user ID.
173 (fd.o #68559, Chengwei Yang)
175 • Document more configuration elements in dbus-daemon(1)
176 (fd.o #69125, Chengwei Yang)
180 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
181 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
183 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
184 disallowed method calls to the audit log, fixing a regression in 1.7.6
185 (fd.o #49062, Colin Walters)
187 • path_namespace='/' in match rules incorrectly matched nothing; it
188 now matches everything. (fd.o #70799, Simon McVittie)
190 D-Bus 1.7.6 (2013-10-09)
193 The “CSI Shrewsbury” release.
195 Build-time configuration changes:
197 • Directory change notification via dnotify on Linux is no longer
198 supported; it hadn't compiled successfully since 2010 in any case.
199 If you don't have inotify (Linux) or kqueue (*BSD), you will need
200 to send SIGHUP to the dbus-daemon when its configuration changes.
201 (fd.o #33001, Chengwei Yang)
203 • Compiling with --disable-userdb-cache is no longer supported;
204 it didn't work since at least 2008, and would lead to an extremely
205 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
208 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
209 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
210 with the Autotools build system. (fd.o #66142, Chengwei Yang)
212 • --with-valgrind=auto enables Valgrind instrumentation if and only if
213 valgrind headers are available. The default is still --with-valgrind=no.
214 (fd.o #56925, Simon McVittie)
218 • Platforms with no 64-bit integer type are no longer supported.
219 (fd.o #65429, Simon McVittie)
221 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
223 • Full test coverage no longer requires dbus-glib, although the tests do not
224 exercise the shared library (only a static copy) if dbus-glib is missing.
225 (fd.o #68852, Simon McVittie)
229 • D-Bus Specification 0.22
230 · Document GetAdtAuditSessionData() and
231 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
232 · Fix example .service file (fd.o #66481, Chengwei Yang)
233 · Don't claim D-Bus is "low-latency" (lower than what?), just
234 give factual statements about it supporting async use
235 (fd.o #65141, Justin Lee)
236 · Document the contents of .service files, and the fact that
237 system services' filenames are constrained
238 (fd.o #66608; Simon McVittie, Chengwei Yang)
240 • Be thread-safe by default on all platforms, even if
241 dbus_threads_init_default() has not been called. For compatibility with
242 older libdbus, library users should continue to call
243 dbus_threads_init_default(): it is harmless to do so.
244 (fd.o #54972, Simon McVittie)
246 • Add GetConnectionCredentials() method (fd.o #54445, Simon)
248 • New API: dbus_setenv(), a simple wrapper around setenv().
249 Note that this is not thread-safe. (fd.o #39196, Simon)
251 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
252 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
253 (connect to a given bus, like dbus-monitor --address=ADDRESS).
254 dbus-send --address still exists for backwards compatibility,
255 but is no longer documented. (fd.o #48816, Andrey Mazo)
258 · "dbus-daemon --nofork" is allowed on Windows again. (fd.o #68852,
263 • Avoid an infinite busy-loop if a signal interrupts waitpid()
264 (fd.o #68945, Simon McVittie)
266 • Clean up memory for parent nodes when objects are unexported
267 (fd.o #60176, Thomas Fitzsimmons)
269 • Make dbus_connection_set_route_peer_messages(x, FALSE) behave as
270 documented. Previously, it assumed its second parameter was TRUE.
271 (fd.o #69165, Chengwei Yang)
273 • Escape addresses containing non-ASCII characters correctly
274 (fd.o #53499, Chengwei Yang)
276 • Document <servicedir> search order correctly (fd.o #66994, Chengwei Yang)
278 • Don't crash on "dbus-send --session / x.y.z" which regressed in 1.7.4.
279 (fd.o #65923, Chengwei Yang)
281 • If malloc() returns NULL in _dbus_string_init() or similar, don't free
282 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
284 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
285 that was never va_start()ed (fd.o #66300, Chengwei Yang)
287 • fix build failure with --enable-stats (fd.o #66004, Chengwei Yang)
289 • fix a regression test on platforms with strict alignment (fd.o #67279,
292 • Avoid calling function parameters "interface" since certain Windows headers
293 have a namespace-polluting macro of that name (fd.o #66493, Ivan Romanov)
295 • Assorted Doxygen fixes (fd.o #65755, Chengwei Yang)
297 • Various thread-safety improvements to static variables (fd.o #68610,
300 • Make "make -j check" work (fd.o #68852, Simon McVittie)
302 • Fix a NULL pointer dereference on an unlikely error path
303 (fd.o #69327, Sviatoslav Chagaev)
305 • Improve valgrind memory pool tracking (fd.o #69326,
308 • Don't over-allocate memory in dbus-monitor (fd.o #69329,
311 • dbus-monitor can monitor dbus-daemon < 1.5.6 again
312 (fd.o #66107, Chengwei Yang)
315 · If accept4() fails with EINVAL, as it can on older Linux kernels
316 with newer glibc, try accept() instead of going into a busy-loop.
317 (fd.o #69026, Chengwei Yang)
318 · If socket() or socketpair() fails with EINVAL or EPROTOTYPE,
319 for instance on Hurd or older Linux with a new glibc, try without
320 SOCK_CLOEXEC. (fd.o #69073; Pino Toscano, Chengwei Yang)
321 · Fix a file descriptor leak on an error code path.
322 (fd.o #69182, Sviatoslav Chagaev)
323 · dbus-run-session: clear some unwanted environment variables
325 · dbus-run-session: compile on FreeBSD (fd.o #66197, Chengwei Yang)
326 · Don't fail the autolaunch test if there is no DISPLAY (fd.o #40352, Simon)
327 · Use dbus-launch from the builddir for testing, not the installed copy
328 (fd.o #37849, Chengwei Yang)
329 · Fix compilation if writev() is unavailable (fd.o #69409,
331 · Remove broken support for LOCAL_CREDS credentials passing, and
332 document where each credential-passing scheme is used (fd.o #60340,
334 · Make autogen.sh work on *BSD by not assuming GNU coreutils functionality
335 (fd.o #35881, #69787; Chengwei Yang)
336 · dbus-monitor: be portable to NetBSD (fd.o #69842, Chengwei Yang)
337 · dbus-launch: stop using non-portable asprintf (fd.o #37849, Simon)
338 · Improve error reporting from the setuid activation helper (fd.o #66728,
342 · Remove unavailable command-line options from 'dbus-daemon --help'
343 (fd.o #42441, Ralf Habacker)
344 · Add support for looking up local TCPv4 clients' credentials on
345 Windows XP via the undocumented AllocateAndGetTcpExTableFromStack
346 function (fd.o #66060, Ralf Habacker)
347 · Fix insufficient dependency-tracking (fd.o #68505, Simon McVittie)
348 · Don't include wspiapi.h, fixing a compiler warning (fd.o #68852,
352 · add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less confusing
353 conditionals (fd.o #66142, Chengwei Yang)

355 · consolidate Autotools and CMake build (fd.o #64875, Ralf Habacker)
356 · fix various unused variables, unusual build configurations
357 etc. (fd.o #65712, #65990, #66005, #66257, #69165, #69410, #70218;
358 Chengwei Yang, Vasiliy Balyasnyy)
360 D-Bus 1.7.4 (2013-06-13)
363 The “but is your thread-safety thread-safe?” release.
367 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
368 of service for system services. Vulnerability reported by Alexandru Cornea.
373 • The Windows version of libdbus now contains a C++ source file, used
374 to provide global initialization when the library is loaded.
375 gcc (mingw*) users should ensure that g++ is also installed.
377 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
378 and was never the recommended option) has been removed. Expat is now a
383 • It should now be safe to call dbus_threads_init_default() from any thread,
384 at any time. Authors of loadable modules and plugins that use libdbus
385 should consider doing so during initialization.
386 (fd.o #54972, Simon McVittie)
388 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
392 · dbus-run-session: experimental new tool to start a temporary D-Bus
393 session, e.g. for regression tests or a text console, replacing
394 certain uses of dbus-launch which weren't really correct
399 • In dbus-daemon, don't crash if a .service file starts with key=value
400 (fd.o #60853, Chengwei Yang)
403 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
404 on a platform not defining LOG_PERROR, such as Solaris or QNX.
405 This regressed in 1.7.0. (Simon)
406 · Fix an assertion failure if we try to activate systemd services before
407 systemd connects to the bus (fd.o #50199, Chengwei Yang)
408 · Avoid compiler warnings for ignoring the return from write()
412 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
413 so that Windows finds them (fd.o #59733, Ralf Habacker)
415 D-Bus 1.7.2 (2013-04-25)
418 The “only partially opaque” release.
420 Configuration changes:
422 • On non-QNX Unix platforms, the default limit on fds per message in the
423 session bus configuration has reduced from 4096 to 1024. The default
424 limit used on the system bus was already 1024. On QNX, both limits are
425 reduced further, to 128.
429 • D-Bus Specification 0.21
430 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
431 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
436 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
437 (i.e. before allocating the slot) rather than returning junk
438 (fd.o #63127, Dan Williams)
440 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
444 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
445 · Under systemd, log to syslog only, not stderr, avoiding duplication
446 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
447 · Under systemd, remove unnecessary dependency on syslog.socket
448 (fd.o #63531, Cristian Rodríguez)
449 · Include alloca.h for alloca() if available, fixing compilation on
450 Solaris 10 (fd.o #63071, Dagobert Michelsen)
451 · Allow use of systemd-logind without the rest of systemd
452 (fd.o #62585, Martin Pitt)
453 · When built with CMake, link to librt and use the right path for
454 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
455 · Reduce the default limit on number of fds per message to 128 under
456 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
459 · Do not claim that all bus clients have the dbus-daemon's credentials;
460 pick up local TCPv4 clients' credentials (process ID and security
461 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,
464 D-Bus 1.7.0 (2013-02-22)
467 The "Disingenuous Assertions" release.
469 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
470 remains the recommended version for long-term-supported distributions
471 or the upcoming GNOME 3.8 release.
473 Build-time configuration changes:
475 • The --with-dbus-session-bus-default-address configure option is no longer
476 supported. Use the new --with-dbus-session-bus-connect-address and
477 --with-dbus-session-bus-listen-address options instead. On Windows, you
478 usually want them to have the same argument; on Unix, the defaults are
481 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
482 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
483 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
485 • cmake/cross-compile.sh has been removed. Instead, please use a
486 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
487 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
488 as documented in "info automake Cross-Compilation", and set
489 PKG_CONFIG_PATH appropriately.
493 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
494 • man2html is no longer used.
498 • D-Bus Specification 0.20
499 · actually say that /org/freedesktop/DBus is the object that
500 implements o.fd.DBus (fd.o #51865, Colin Walters)
501 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
502 · stop claiming that all basic types work just like INT32 (strings don't!)
504 • The "source code" for the man pages is now Docbook XML, eliminating
505 the outdated duplicate copies used when building with CMake.
506 (fd.o #59805; Ralf Habacker, Simon McVittie)
510 • In the activation helper, when compiled for tests, do not reset the system
511 bus address, fixing the regression tests. (fd.o #52202, Simon)
513 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
514 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
516 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,
519 • Under CMake, prefer xmlto over meinproc (fd.o #59733, Ralf Habacker)
521 • Stop duplicating CMake's own logic to find libexpat
522 (fd.o #59733, Ralf Habacker)
524 • Don't assume CMake host and build system are the same (fd.o #59733,
527 • Avoid deprecation warnings for GLib 2.35 (fd.o #59971, Simon McVittie)
530 · Check for functions in libpthread correctly, fixing compilation on
531 (at least) OpenBSD (fd.o #47239, Simon)
532 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
534 · Update sd-daemon.[ch] from systemd (fd.o #60681)
535 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
538 · The default session bus listening and connecting address is now
539 "autolaunch:", which makes D-Bus on Windows interoperate with itself
540 and GDBus "out of the box". Use the configure options and cmake variables
541 described above if you require a different autolaunch scope.
542 (fd.o #38201, Simon McVittie)
543 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
545 • Create session.d, system.d directories under CMake (fd.o #41319,
548 D-Bus 1.6.8 (2012-09-28)
551 The "Fix one thing, break another" release.
553 • Follow up to CVE-2012-3524: The additional hardening
554 work to use __secure_getenv() as a followup to bug #52202
555 broke certain configurations of gnome-keyring. Given
556 the difficulty of making this work without extensive
557 changes to gnome-keyring, use of __secure_getenv() is
560 D-Bus 1.6.6 (2012-09-28)
563 The "Clear the environment in your setuid binaries, please" release.
565 • CVE-2012-3524: Don't access environment variables (fd.o #52202)
566 Thanks to work and input from Colin Walters, Simon McVittie,
567 Geoffrey Thomas, and others.
569 · Fix compilation on Solaris (fd.o #53286, Jonathan Perkin)
570 · Work around interdependent headers on OpenBSD by including sys/types.h
571 before each use of sys/socket.h (fd.o #54418, Brad Smith)
573 D-Bus 1.6.4 (2012-07-18)
576 • Detect that users are "at the console" correctly when configured with
577 a non-default path such as --enable-console-auth-dir=/run/console
578 (fd.o #51521, Dave Reisner)
580 • Remove an incorrect assertion from DBusTransport (fd.o #51657,
583 • Make --enable-developer default to "no" (regression in 1.6.2;
584 fd.o #51657, Simon McVittie)
587 · Launch dbus-daemon correctly if its path contains a space
588 (fd.o #49450, Wolfgang Baron)
590 D-Bus 1.6.2 (2012-06-27)
593 The "Ice Cabbage" release.
595 • Change how we create /var/lib/dbus so it works under Automake >= 1.11.4
596 (fd.o #51406, Simon McVittie)
598 • Don't return from dbus_pending_call_set_notify with a lock held on OOM
599 (fd.o #51032, Simon McVittie)
601 • Disconnect "developer mode" (assertions, verbose mode etc.) from
602 Automake maintainer mode. D-Bus developers should now configure with
603 --enable-developer. Automake maintainer mode is now on by default;
604 distributions can disable it with --disable-maintainer-mode.
605 (fd.o #34671, Simon McVittie)
607 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
608 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)
611 · Check for libpthread under CMake on Unix (fd.o #47237, Simon McVittie)
613 D-Bus 1.6.0 (2012-06-05)
616 The “soul of this machine has improved” release.
618 This version starts a new stable branch of D-Bus: only bug fixes will
619 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
621 Summary of changes since 1.4.x:
624 · PTHREAD_MUTEX_RECURSIVE on Unix
625 · compiler support for 64-bit integers (int64_t or equivalent)
627 • D-Bus Specification v0.19
629 • New dbus-daemon features
630 · <allow own_prefix="com.example.Service"/> rules allow the service to
631 own names like com.example.Service.Instance3
632 · optional systemd integration when checking at_console policies
633 · --nopidfile option, mainly for use by systemd
634 · path_namespace and arg0namespace may appear in match rules
635 · eavesdropping is disabled unless the match rule contains eavesdrop=true
638 · functions to validate various string types (dbus_validate_path() etc.)
639 · dbus_type_is_valid()
640 · DBusBasicValue, a union of every basic type
643 · removed an unsafe reimplementation of recursive mutexes
644 · dbus-daemon no longer busy-loops if it has far too many file descriptors
645 · dbus-daemon.exe --print-address works on Windows
646 · all the other bug fixes from 1.4.20
648 • Other major implementation changes
649 · on Linux, dbus-daemon uses epoll if supported, for better scalability
650 · dbus_threads_init() ignores its argument and behaves like
651 dbus_threads_init_default() instead
652 · removed the per-connection link cache, improving dbus-daemon performance
655 · optional Valgrind instrumentation (--with-valgrind)
656 · optional Stats interface on the dbus-daemon (--enable-stats)
657 · optionally abort whenever malloc() fails (--enable-embedded-tests
658 and export DBUS_MALLOC_CANNOT_FAIL=1)
660 Changes since 1.5.12:
662 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
663 spec-compliance (fd.o #48580, David Zeuthen)
665 • Don't use install(1) within the source/build trees, fixing the build as
666 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
668 • Add missing commas in some tcp and nonce-tcp addresses, and remove
669 an unused duplicate copy of the nonce-tcp transport in Windows builds
670 (fd.o #45896, Simon McVittie)
672 D-Bus 1.5.12 (2012-03-27)
675 The “Big Book of Science” release.
677 • Add public API to validate various string types:
678 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
679 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
680 (fd.o #39549, Simon McVittie)
682 • Turn DBusBasicValue into public API so bindings don't need to invent their
683 own "union of everything" type (fd.o #11191, Simon McVittie)
685 • Enumerate data files included in the build rather than using find(1)
686 (fd.o #33840, Simon McVittie)
688 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
689 in dbus-daemon (fd.o #46273, Alban Crequy)
692 · make dbus-daemon.exe --print-address (and --print-pid) work again
693 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
694 · fix duplicate case value when compiling against mingw-w64
695 (fd.o #47321, Andoni Morales Alastruey)
697 D-Bus 1.5.10 (2012-02-21)
700 The "fire in Delerium" release.
702 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
703 and SUSv2) is now required.
705 • D-Bus Specification 0.19:
706 · Formally define unique connection names and well-known bus names,
707 and document best practices for interface, bus, member and error names,
708 and object paths (fd.o #37095, Simon McVittie)
709 · Document the search path for session and system services on Unix, and
710 where they should be installed by build systems (fd.o #21620, fd.o #35306;
712 · Document the systemd transport (fd.o #35232, Lennart Poettering)
714 • Make dbus_threads_init() use the same built-in threading implementation
715 as dbus_threads_init_default(); the user-specified primitives that it
716 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
718 • Allow all configured auth mechanisms, not just one (fd.o #45106,
721 • Improve cmake build system (Ralf Habacker):
722 · simplify XML parser dependencies (fd.o #41027)
723 · generate build timestamp (fd.o #41029)
724 · only create batch files on Windows
725 · fix option and cache syntax
726 · add help-options target
727 · share dbus-arch-deps.h.in with autotools rather than having our
728 own version (fd.o #41033)
730 • Build tests successfully with older GLib, as found in e.g. Debian 6
731 (fd.o #41219, Simon McVittie)
733 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
735 • Build documentation correctly if man2html doesn't support filenames on
736 its command-line (fd.o #43875, Jack Nagel)
738 • Improve test coverage. To get even more coverage, run the tests with
739 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
741 • Reduce the size of the shared library by moving functionality only used
742 by dbus-daemon, tests etc. into their internal library and deleting
743 unused code (fd.o #34976, #39759; Simon McVittie)
745 • Add dbus-daemon --nopidfile option, overriding the configuration, for
746 setups where the default configuration must include <pidfile/> to avoid
747 breaking traditional init, but the pid file is in fact unnecessary; use
748 it under systemd to improve startup time a bit (fd.o #45520,
751 • Optionally (if configured --with-valgrind) add instrumentation to debug
752 libdbus and associated tools more meaningfully under Valgrind
753 (fd.o #37286, Simon McVittie)
755 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
757 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
759 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
760 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
761 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
764 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
768 · Replace our broken reimplementation of recursive mutexes, which has
769 been broken since 2006, with an ordinary pthreads recursive mutex
770 (fd.o #43744; Sigmund Augdal, Simon McVittie)
771 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
772 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
773 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
774 · When running under systemd, use it instead of ConsoleKit to check
775 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
776 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
777 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
778 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
779 (fd.o #41218, Simon McVittie)
780 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
781 helper doesn't obey environment variables to avoid privilege escalation
782 attacks, so make the system bus follow the same rules
783 (fd.o #21620, Simon McVittie)
786 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
787 Jesper Dam, Ralf Habacker)
788 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
791 D-Bus 1.5.8 (2011-09-21)
794 The "cross-metering" release.
796 In addition to dead code removal and refactoring, this release contains all
797 of the bugfixes from 1.4.16.
799 • Clean up dead code, and make more warnings fatal in development builds
800 (fd.o #39231, fd.o #41012; Simon McVittie)
802 • If full test coverage is requested via --enable-tests, strictly require
803 Python, pygobject and dbus-python, which are required by some tests; if not,
804 and Python is missing, skip those tests rather than failing
805 (fd.o #37847, Simon McVittie)
807 • When using cmake, provide the same version-info API in the installed headers
808 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
810 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
812 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
814 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
817 • Fix duplicates in authors list (Ralf Habacker)
819 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
820 (fd.o #39879, Chris Mayo)
822 • Fix a small memory leak, and a failure to report errors, when updating
823 a service file entry for activation (fd.o #39230, Simon McVittie)
826 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
827 Brian Cameron, Simon McVittie)
828 · On systems that use libcap-ng but not systemd, drop supplemental groups
829 when switching to the daemon user (Red Hat #726953, Steve Grubb)
830 · Make the cmake build work again on GNU platforms (fd.o #29228,
832 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
833 like Solaris (fd.o #40313, Dagobert Michelsen)
834 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
835 (fd.o #40235, Simon McVittie)
836 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
837 (fd.o #39987, Simon McVittie)
838 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
839 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
842 · Fix compilation on MSVC, which doesn't understand "inline" with its
843 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
844 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
845 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
847 D-Bus 1.5.6 (2011-07-29)
850 The "weird, gravy-like aftertaste" release.
852 In addition to new features and refactoring, this release contains all of the
853 bugfixes from 1.4.14.
855 Potentially incompatible (Bustle and similar debugging tools will need
856 changes to work as intended):
858 • Do not allow match rules to "eavesdrop" (receive messages intended for a
859 different recipient) by mistake: eavesdroppers must now opt-in to this
860 behaviour by putting "eavesdrop='true'" in the match rule, which will
861 not have any practical effect on buses where eavesdropping is not allowed
862 (fd.o #37890, Cosimo Alfarano)
866 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
867 Cosimo Alfarano, Simon McVittie)
868 · add the "eavesdrop" keyword to match rules
869 · define eavesdropping, unicast messages and broadcast messages
870 · stop claiming that match rules are needed to match unicast messages to you
871 · promote the type system to be a top-level section
873 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
874 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
875 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
877 • Consistently use atomic operations on everything that is ever manipulated
878 via atomic ops, as was done for changes to DBusConnection's refcount in
879 1.4.12 (fd.o #38005, Simon McVittie)
881 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
884 • Make "make check" in a clean tree work, by not running tests until
885 test data has been set up (fd.o #34405, Simon McVittie)
887 • The dbus-daemon no longer busy-loops if it has a very large number of file
888 descriptors (fd.o #23194, Simon McVittie)
890 • Refactor message flow through dispatching to avoid locking violations if
891 the bus daemon's message limit is hit; remove the per-connection link cache,
892 which was meant to improve performance, but now reduces it (fd.o #34393,
895 • Some cmake fixes (Ralf Habacker)
897 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
898 Simon McVittie, Lennart Poettering)
900 • Stop storing two extra byte order indicators in each D-Bus message
901 (fd.o #38287, Simon McVittie)
903 • Add an optional Stats interface which can be used to get statistics from
904 a running dbus-daemon if enabled at configure time with --enable-stats
905 (fd.o #34040, Simon McVittie)
907 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
909 • Documentation (fd.o #36156, Simon McVittie):
910 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
911 · install more documentation automatically, including man2html output
912 · put dbus.devhelp in the right place (it must go in ${htmldir})
915 · look for system services in /lib/dbus-1/system-services in addition to all
916 the other well-known locations; note that this should always be /lib,
917 even on platforms where shared libraries on the root FS would go in /lib64,
918 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
919 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
921 • Windows-specific (Ralf Habacker):
922 · fix use of a mutex for autolaunch server detection
923 · don't crash on malloc failure in _dbus_printf_string_upper_bound
925 D-Bus 1.5.4 (2011-06-10)
928 Security (local denial of service):
930 • Byte-swap foreign-endian messages correctly, preventing a long-standing
931 local DoS if foreign-endian messages are relayed through the dbus-daemon
932 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
933 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
937 • The constant to use for an infinite timeout now has a name,
938 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
939 which can be used for source compatibility with older versions of libdbus.
941 • If GLib and DBus-GLib are already installed, more tests will be built,
942 providing better coverage. The new tests can also be installed via
943 ./configure --enable-installed-tests
944 for system integration testing, if required. (fd.o #34570, Simon McVittie)
948 • Consistently use atomic operations for the DBusConnection's refcount,
949 fixing potential threading problems (fd.o #38005, Simon McVittie)
951 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
952 small (300KiB on x86-64) and it frequently doesn't work in unusual
953 toolchains. To optimize for minimum installed size, you should benchmark
954 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
955 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
957 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
958 (fd.o #35880, Timothy Redaelli)
960 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
961 when not using a DESTDIR (fd.o #37870, Simon McVittie)
963 • Windows-specific changes:
964 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
966 D-Bus 1.5.2 (2011-06-01)
969 The "Boar Hunter" release.
971 Notes for distributors:
973 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
974 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
975 toolchain supports it reliably, via something like:
977 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
979 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
983 • D-Bus Specification v0.17
984 · Reserve the extra characters used in signatures by GVariant
985 (fd.o #34529, Simon McVittie)
986 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
987 • Don't force -fPIE: distributions and libtool know better than we do whether
988 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
989 • Allow --disable-gc-sections, in case your toolchain offers the
990 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
991 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
992 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
993 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
994 • Ensure that maintainers upload documentation with the right permissions
995 (fd.o #36130, Simon McVittie)
996 • Don't force users of libdbus to be linked against -lpthread, -lrt
997 (fd.o #32827, Simon McVittie)
998 • Log system-bus activation information to syslog (fd.o #35705,
1000 • Log messages dropped due to quotas to syslog (fd.o #35358,
1002 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
1003 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
1004 (fd.o #35228, Lennart Poettering)
1005 • In the regression tests, don't report fds as "leaked" if they were open
1006 on startup (fd.o #35173, Simon McVittie)
1007 • Make dbus-monitor bail out if asked to monitor more than one bus,
1008 rather than silently using the last one (fd.o #26548, Will Thompson)
1009 • Clarify documentation (fd.o #35182, Simon McVittie)
1010 • Clean up minor dead code and some incorrect error handling
1011 (fd.o #33128, fd.o #29881; Simon McVittie)
1012 • Check that compiler options are supported before using them (fd.o #19681,
1015 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
1017 D-Bus 1.5.0 (2011-04-11)
1020 The "you never know when you need to tow something from your giant
1021 flying shark" release.
1023 • D-Bus Specification v0.16
1024 · Add support for path_namespace and arg0namespace in match rules
1025 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
1026 · Make argNpath support object paths, not just object-path-like strings,
1027 and document it better (fd.o #31818, Will Thompson)
1028 • Let the bus daemon implement more than one interface (fd.o #33757,
1030 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
1032 • Require user intervention to compile with missing 64-bit support
1033 (fd.o #35114, Simon McVittie)
1034 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
1035 • Raise UnknownObject instead of UnknownMethod for calls to methods on
1036 paths that are not part of the object tree, and UnknownInterface for calls
1037 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
1039 D-Bus 1.4.8 (2011-04-08)
1042 The "It's like the beginning of a lobster" release.
1044 • Rename configure.in to configure.ac, and update it to modern conventions
1045 (fd.o #32245; Javier Jardón, Simon McVittie)
1046 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
1048 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
1049 --disable-x11-autolaunch configure option to prevent it altogether
1050 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
1051 • Install the documentation, and an index for Devhelp (fd.o #13495,
1052 Debian #454142; Simon McVittie, Matthias Clasen)
1053 • If checks are not disabled, check validity of string-like types and
1054 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
1055 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
1056 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
1057 • Break up a huge conditional in config-parser so gcov can produce coverage
1058 data (fd.o #10887, Simon McVittie)
1059 • List which parts of the Desktop Entry specification are applicable to
1060 .service files (fd.o #19159, Sven Herzberg)
1061 • Don't suppress service activation if two services have the same Exec=
1062 (fd.o #35750, Colin Walters)
1064 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
1066 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
1067 (fd.o #32805, Mark Brand)
1069 D-Bus 1.4.6 (2010-02-17)
1072 The "1, 2, miss a few, 99, 100" release.
1074 • Remove unfinished changes intended to support GTest-based tests,
1075 which were mistakenly included in 1.4.4
1077 D-Bus 1.4.4 (2010-02-17)
1080 • Switch back to using even micro versions for stable releases; 1.4.1
1081 should have been called 1.4.2, so skip that version number
1082 • Don't leave bad file descriptors being watched when spawning processes,

1115 D-Bus 1.4.1 (20 December 2010)
1118 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
1119 crash the bus. The existing restriction to 64-levels of nesting previously
1120 only applied to the static type signature; now it also applies to dynamic
1121 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
