1 D-Bus 1.5.10 (2012-02-21)
4 The "fire in Delerium" release.
6 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
7 and SUSv2) is now required.
9 • D-Bus Specification 0.19:
10 · Formally define unique connection names and well-known bus names,
11 and document best practices for interface, bus, member and error names,
12 and object paths (fd.o #37095, Simon McVittie)
13 · Document the search path for session and system services on Unix, and
14 where they should be installed by build systems (fd.o #21620, fd.o #35306;
16 · Document the systemd transport (fd.o #35232, Lennart Poettering)
18 • Make dbus_threads_init() use the same built-in threading implementation
19 as dbus_threads_init_default(); the user-specified primitives that it
20 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
22 • Allow all configured auth mechanisms, not just one (fd.o #45106,
25 • Improve cmake build system (Ralf Habacker):
26 · simplify XML parser dependencies (fd.o #41027)
27 · generate build timestamp (fd.o #41029)
28 · only create batch files on Windows
29 · fix option and cache syntax
30 · add help-options target
31 · share dbus-arch-deps.h.in with autotools rather than having our
32 own version (fd.o #41033)
34 • Build tests successfully with older GLib, as found in e.g. Debian 6
35 (fd.o #41219, Simon McVittie)
37 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
39 • Build documentation correctly if man2html doesn't support filenames on
40 its command-line (fd.o #43875, Jack Nagel)
42 • Improve test coverage. To get even more coverage, run the tests with
43 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
45 • Reduce the size of the shared library by moving functionality only used
46 by dbus-daemon, tests etc. into their internal library and deleting
47 unused code (fd.o #34976, #39759; Simon McVittie)
49 • Add dbus-daemon --nopidfile option, overriding the configuration, for
50 setups where the default configuration must include <pidfile/> to avoid
51 breaking traditional init, but the pid file is in fact unnecessary; use
52 it under systemd to improve startup time a bit (fd.o #45520,
55 • Optionally (if configured --with-valgrind) add instrumentation to debug
56 libdbus and associated tools more meaningfully under Valgrind
57 (fd.o #37286, Simon McVittie)
59 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
61 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
63 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
64 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
65 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
68 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
72 · Replace our broken reimplementation of recursive mutexes, which has
73 been broken since 2006, with an ordinary pthreads recursive mutex
74 (fd.o #43744; Sigmund Augdal, Simon McVittie)
75 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
76 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
77 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
78 · When running under systemd, use it instead of ConsoleKit to check
79 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
80 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
81 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
82 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
83 (fd.o #41218, Simon McVittie)
84 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
85 helper doesn't obey environment variables to avoid privilege escalation
86 attacks, so make the system bus follow the same rules
87 (fd.o #21620, Simon McVittie)
90 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
91 Jesper Dam, Ralf Habacker)
92 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
95 D-Bus 1.5.8 (2011-09-21)
98 The "cross-metering" release.
100 In addition to dead code removal and refactoring, this release contains all
101 of the bugfixes from 1.4.16.
103 • Clean up dead code, and make more warnings fatal in development builds
104 (fd.o #39231, fd.o #41012; Simon McVittie)
106 • If full test coverage is requested via --enable-tests, strictly require
107 Python, pygobject and dbus-python, which are required by some tests; if not,
108 and Python is missing, skip those tests rather than failing
109 (fd.o #37847, Simon McVittie)
111 • When using cmake, provide the same version-info API in the installed headers
112 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
114 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
116 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
118 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
121 • Fix duplicates in authors list (Ralf Habacker)
123 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
124 (fd.o #39879, Chris Mayo)
126 • Fix a small memory leak, and a failure to report errors, when updating
127 a service file entry for activation (fd.o #39230, Simon McVittie)
130 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
131 Brian Cameron, Simon McVittie)
132 · On systems that use libcap-ng but not systemd, drop supplemental groups
133 when switching to the daemon user (Red Hat #726953, Steve Grubb)
134 · Make the cmake build work again on GNU platforms (fd.o #29228,
136 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
137 like Solaris (fd.o #40313, Dagobert Michelsen)
138 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
139 (fd.o #40235, Simon McVittie)
140 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
141 (fd.o #39987, Simon McVittie)
142 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
143 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
146 · Fix compilation on MSVC, which doesn't understand "inline" with its
147 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
148 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
149 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
151 D-Bus 1.5.6 (2011-07-29)
154 The "weird, gravy-like aftertaste" release.
156 In addition to new features and refactoring, this release contains all of the
157 bugfixes from 1.4.14.
159 Potentially incompatible (Bustle and similar debugging tools will need
160 changes to work as intended):
162 • Do not allow match rules to "eavesdrop" (receive messages intended for a
163 different recipient) by mistake: eavesdroppers must now opt-in to this
164 behaviour by putting "eavesdrop='true'" in the match rule, which will
165 not have any practical effect on buses where eavesdropping is not allowed
166 (fd.o #37890, Cosimo Alfarano)
170 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
171 Cosimo Alfarano, Simon McVittie)
172 · add the "eavesdrop" keyword to match rules
173 · define eavesdropping, unicast messages and broadcast messages
174 · stop claiming that match rules are needed to match unicast messages to you
175 · promote the type system to be a top-level section
177 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
178 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
179 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
181 • Consistently use atomic operations on everything that is ever manipulated
182 via atomic ops, as was done for changes to DBusConnection's refcount in
183 1.4.12 (fd.o #38005, Simon McVittie)
185 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
188 • Make "make check" in a clean tree work, by not running tests until
189 test data has been set up (fd.o #34405, Simon McVittie)
191 • The dbus-daemon no longer busy-loops if it has a very large number of file
192 descriptors (fd.o #23194, Simon McVittie)
194 • Refactor message flow through dispatching to avoid locking violations if
195 the bus daemon's message limit is hit; remove the per-connection link cache,
196 which was meant to improve performance, but now reduces it (fd.o #34393,
199 • Some cmake fixes (Ralf Habacker)
201 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
202 Simon McVittie, Lennart Poettering)
204 • Stop storing two extra byte order indicators in each D-Bus message
205 (fd.o #38287, Simon McVittie)
207 • Add an optional Stats interface which can be used to get statistics from
208 a running dbus-daemon if enabled at configure time with --enable-stats
209 (fd.o #34040, Simon McVittie)
211 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
213 • Documentation (fd.o #36156, Simon McVittie):
214 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
215 · install more documentation automatically, including man2html output
216 · put dbus.devhelp in the right place (it must go in ${htmldir})
219 · look for system services in /lib/dbus-1/system-services in addition to all
220 the other well-known locations; note that this should always be /lib,
221 even on platforms where shared libraries on the root FS would go in /lib64,
222 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
223 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
225 • Windows-specific (Ralf Habacker):
226 · fix use of a mutex for autolaunch server detection
227 · don't crash on malloc failure in _dbus_printf_string_upper_bound
229 D-Bus 1.5.4 (2011-06-10)
232 Security (local denial of service):
234 • Byte-swap foreign-endian messages correctly, preventing a long-standing
235 local DoS if foreign-endian messages are relayed through the dbus-daemon
236 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
237 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
241 • The constant to use for an infinite timeout now has a name,
242 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
243 which can be used for source compatibility with older versions of libdbus.
245 • If GLib and DBus-GLib are already installed, more tests will be built,
246 providing better coverage. The new tests can also be installed via
247 ./configure --enable-installed-tests
248 for system integration testing, if required. (fd.o #34570, Simon McVittie)
252 • Consistently use atomic operations for the DBusConnection's refcount,
253 fixing potential threading problems (fd.o #38005, Simon McVittie)
255 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
256 small (300KiB on x86-64) and it frequently doesn't work in unusual
257 toolchains. To optimize for minimum installed size, you should benchmark
258 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
259 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
261 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
262 (fd.o #35880, Timothy Redaelli)
264 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
265 when not using a DESTDIR (fd.o #37870, Simon McVittie)
267 • Windows-specific changes:
268 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
270 D-Bus 1.5.2 (2011-06-01)
273 The "Boar Hunter" release.
275 Notes for distributors:
277 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
278 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
279 toolchain supports it reliably, via something like:
281 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
283 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
287 • D-Bus Specification v0.17
288 · Reserve the extra characters used in signatures by GVariant
289 (fd.o #34529, Simon McVittie)
290 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
291 • Don't force -fPIE: distributions and libtool know better than we do whether
292 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
293 • Allow --disable-gc-sections, in case your toolchain offers the
294 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
295 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
296 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
297 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
298 • Ensure that maintainers upload documentation with the right permissions
299 (fd.o #36130, Simon McVittie)
300 • Don't force users of libdbus to be linked against -lpthread, -lrt
301 (fd.o #32827, Simon McVittie)
302 • Log system-bus activation information to syslog (fd.o #35705,
304 • Log messages dropped due to quotas to syslog (fd.o #35358,
306 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
307 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
308 (fd.o #35228, Lennart Poettering)
309 • In the regression tests, don't report fds as "leaked" if they were open
310 on startup (fd.o #35173, Simon McVittie)
311 • Make dbus-monitor bail out if asked to monitor more than one bus,
312 rather than silently using the last one (fd.o #26548, Will Thompson)
313 • Clarify documentation (fd.o #35182, Simon McVittie)
314 • Clean up minor dead code and some incorrect error handling
315 (fd.o #33128, fd.o #29881; Simon McVittie)
316 • Check that compiler options are supported before using them (fd.o #19681,
319 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
321 D-Bus 1.5.0 (2011-04-11)
324 The "you never know when you need to tow something from your giant
325 flying shark" release.
327 • D-Bus Specification v0.16
328 · Add support for path_namespace and arg0namespace in match rules
329 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
330 · Make argNpath support object paths, not just object-path-like strings,
331 and document it better (fd.o #31818, Will Thompson)
332 • Let the bus daemon implement more than one interface (fd.o #33757,
334 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
336 • Require user intervention to compile with missing 64-bit support
337 (fd.o #35114, Simon McVittie)
338 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
339 • Raise UnknownObject instead of UnknownMethod for calls to methods on
340 paths that are not part of the object tree, and UnknownInterface for calls
341 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
343 D-Bus 1.4.8 (2011-04-08)
346 The "It's like the beginning of a lobster" release.
348 • Rename configure.in to configure.ac, and update it to modern conventions
349 (fd.o #32245; Javier Jardón, Simon McVittie)
350 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
352 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
353 --disable-x11-autolaunch configure option to prevent it altogether
354 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
355 • Install the documentation, and an index for Devhelp (fd.o #13495,
356 Debian #454142; Simon McVittie, Matthias Clasen)
357 • If checks are not disabled, check validity of string-like types and
358 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
359 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
360 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
361 • Break up a huge conditional in config-parser so gcov can produce coverage
362 data (fd.o #10887, Simon McVittie)
363 • List which parts of the Desktop Entry specification are applicable to
364 .service files (fd.o #19159, Sven Herzberg)
365 • Don't suppress service activation if two services have the same Exec=
366 (fd.o #35750, Colin Walters)
368 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
370 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
371 (fd.o #32805, Mark Brand)
373 D-Bus 1.4.6 (2010-02-17)
376 The "1, 2, miss a few, 99, 100" release.
378 • Remove unfinished changes intended to support GTest-based tests,
379 which were mistakenly included in 1.4.4
381 D-Bus 1.4.4 (2010-02-17)
384 • Switch back to using even micro versions for stable releases; 1.4.1
385 should have been called 1.4.2, so skip that version number
386 • Don't leave bad file descriptors being watched when spawning processes,
387 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
388 also LP#656134, LP#680444, LP#713157)
389 • Check for MSG_NOSIGNAL correctly

391 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
392 (fd.o #32262, NB#180486)
393 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,
394 fd.o #33128, fd.o #33277, fd.o #33126, NB#180486)
395 • Avoid possible symlink attacks in /tmp during compilation (fd.o #32854)

397 • Improve gcc malloc annotations (fd.o #32710)
398 • If the system bus is launched via systemd, protect it from the OOM killer
399 • Documentation improvements (fd.o #11190)

415 · support credentials-passing (fd.o #32542)
417 · opt-in to thread safety (fd.o #33464)
419 D-Bus 1.4.1 (20 December 2010)
422 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
423 crash the bus. The existing restriction to 64-levels of nesting previously
424 only applied to the static type signature; now it also applies to dynamic
425 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
427 • OS X portability fixes, including launchd support.
428 • Windows autolaunch improvements.
431 D-Bus 1.4.0 (6 Sep 2010)

438 - Various portability fixes, in particular to Windows platforms
439 - Support forking bus services, for compatibility
441 D-Bus 1.3.0 (29 July 2009)
443 - ability for dbus-send to send to any bus (--address)
444 - file descriptor passing on Unix socket transports
445 - use of GCC atomic intrinsics for better processor support
446 (requires -march=i486 or above for x86 compilation)
447 - thread-safe FD_CLOEXEC setting on recent Linux kernels (2.6.24-27 and up)
448 and glibc (2.9 for pipe2 and 2.10 for accept4)
