1 D-Bus 1.5.14 (UNRELEASED)
6 D-Bus 1.5.12 (2012-03-27)
9 The “Big Book of Science” release.
11 • Add public API to validate various string types:
12 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
13 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
14 (fd.o #39549, Simon McVittie)
16 • Turn DBusBasicValue into public API so bindings don't need to invent their
17 own "union of everything" type (fd.o #11191, Simon McVittie)
19 • Enumerate data files included in the build rather than using find(1)
20 (fd.o #33840, Simon McVittie)
22 • Add support for policy rules like <allow own_prefix="com.example.Service"/>
23 in dbus-daemon (fd.o #46273, Alban Crequy)
26 · make dbus-daemon.exe --print-address (and --print-pid) work again
27 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
28 · fix duplicate case value when compiling against mingw-w64
29 (fd.o #47321, Andoni Morales Alastruey)
31 D-Bus 1.5.10 (2012-02-21)
34 The "fire in Delerium" release.
36 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
37 and SUSv2) is now required.
39 • D-Bus Specification 0.19:
40 · Formally define unique connection names and well-known bus names,
41 and document best practices for interface, bus, member and error names,
42 and object paths (fd.o #37095, Simon McVittie)
43 · Document the search path for session and system services on Unix, and
44 where they should be installed by build systems (fd.o #21620, fd.o #35306;
46 · Document the systemd transport (fd.o #35232, Lennart Poettering)
48 • Make dbus_threads_init() use the same built-in threading implementation
49 as dbus_threads_init_default(); the user-specified primitives that it
50 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
52 • Allow all configured auth mechanisms, not just one (fd.o #45106,
55 • Improve cmake build system (Ralf Habacker):
56 · simplify XML parser dependencies (fd.o #41027)
57 · generate build timestamp (fd.o #41029)
58 · only create batch files on Windows
59 · fix option and cache syntax
60 · add help-options target
61 · share dbus-arch-deps.h.in with autotools rather than having our
62 own version (fd.o #41033)
64 • Build tests successfully with older GLib, as found in e.g. Debian 6
65 (fd.o #41219, Simon McVittie)
67 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
69 • Build documentation correctly if man2html doesn't support filenames on
70 its command-line (fd.o #43875, Jack Nagel)
72 • Improve test coverage. To get even more coverage, run the tests with
73 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
75 • Reduce the size of the shared library by moving functionality only used
76 by dbus-daemon, tests etc. into their internal library and deleting
77 unused code (fd.o #34976, #39759; Simon McVittie)
79 • Add dbus-daemon --nopidfile option, overriding the configuration, for
80 setups where the default configuration must include <pidfile/> to avoid
81 breaking traditional init, but the pid file is in fact unnecessary; use
82 it under systemd to improve startup time a bit (fd.o #45520,
85 • Optionally (if configured --with-valgrind) add instrumentation to debug
86 libdbus and associated tools more meaningfully under Valgrind
87 (fd.o #37286, Simon McVittie)
89 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
91 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
93 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
94 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
95 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
98 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
102 · Replace our broken reimplementation of recursive mutexes, which has
103 been broken since 2006, with an ordinary pthreads recursive mutex
104 (fd.o #43744; Sigmund Augdal, Simon McVittie)
105 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
106 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
107 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
108 · When running under systemd, use it instead of ConsoleKit to check
109 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
110 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
111 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
112 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
113 (fd.o #41218, Simon McVittie)
114 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
115 helper doesn't obey environment variables to avoid privilege escalation
116 attacks, so make the system bus follow the same rules
117 (fd.o #21620, Simon McVittie)
120 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
121 Jesper Dam, Ralf Habacker)
122 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
125 D-Bus 1.5.8 (2011-09-21)
128 The "cross-metering" release.
130 In addition to dead code removal and refactoring, this release contains all
131 of the bugfixes from 1.4.16.
133 • Clean up dead code, and make more warnings fatal in development builds
134 (fd.o #39231, fd.o #41012; Simon McVittie)
136 • If full test coverage is requested via --enable-tests, strictly require
137 Python, pygobject and dbus-python, which are required by some tests; if not,
138 and Python is missing, skip those tests rather than failing
139 (fd.o #37847, Simon McVittie)
141 • When using cmake, provide the same version-info API in the installed headers
142 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
144 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
146 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
148 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
151 • Fix duplicates in authors list (Ralf Habacker)
153 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
154 (fd.o #39879, Chris Mayo)
156 • Fix a small memory leak, and a failure to report errors, when updating
157 a service file entry for activation (fd.o #39230, Simon McVittie)
160 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
161 Brian Cameron, Simon McVittie)
162 · On systems that use libcap-ng but not systemd, drop supplemental groups
163 when switching to the daemon user (Red Hat #726953, Steve Grubb)
164 · Make the cmake build work again on GNU platforms (fd.o #29228,
166 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
167 like Solaris (fd.o #40313, Dagobert Michelsen)
168 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
169 (fd.o #40235, Simon McVittie)
170 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
171 (fd.o #39987, Simon McVittie)
172 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
173 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
176 · Fix compilation on MSVC, which doesn't understand "inline" with its
177 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
178 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
179 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
181 D-Bus 1.5.6 (2011-07-29)
184 The "weird, gravy-like aftertaste" release.
186 In addition to new features and refactoring, this release contains all of the
187 bugfixes from 1.4.14.
189 Potentially incompatible (Bustle and similar debugging tools will need
190 changes to work as intended):
192 • Do not allow match rules to "eavesdrop" (receive messages intended for a
193 different recipient) by mistake: eavesdroppers must now opt-in to this
194 behaviour by putting "eavesdrop='true'" in the match rule, which will
195 not have any practical effect on buses where eavesdropping is not allowed
196 (fd.o #37890, Cosimo Alfarano)
200 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
201 Cosimo Alfarano, Simon McVittie)
202 · add the "eavesdrop" keyword to match rules
203 · define eavesdropping, unicast messages and broadcast messages
204 · stop claiming that match rules are needed to match unicast messages to you
205 · promote the type system to be a top-level section
207 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
208 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
209 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
211 • Consistently use atomic operations on everything that is ever manipulated
212 via atomic ops, as was done for changes to DBusConnection's refcount in
213 1.4.12 (fd.o #38005, Simon McVittie)
215 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
218 • Make "make check" in a clean tree work, by not running tests until
219 test data has been set up (fd.o #34405, Simon McVittie)
221 • The dbus-daemon no longer busy-loops if it has a very large number of file
222 descriptors (fd.o #23194, Simon McVittie)
224 • Refactor message flow through dispatching to avoid locking violations if
225 the bus daemon's message limit is hit; remove the per-connection link cache,
226 which was meant to improve performance, but now reduces it (fd.o #34393,
229 • Some cmake fixes (Ralf Habacker)
231 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
232 Simon McVittie, Lennart Poettering)
234 • Stop storing two extra byte order indicators in each D-Bus message
235 (fd.o #38287, Simon McVittie)
237 • Add an optional Stats interface which can be used to get statistics from
238 a running dbus-daemon if enabled at configure time with --enable-stats
239 (fd.o #34040, Simon McVittie)
241 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
243 • Documentation (fd.o #36156, Simon McVittie):
244 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
245 · install more documentation automatically, including man2html output
246 · put dbus.devhelp in the right place (it must go in ${htmldir})
249 · look for system services in /lib/dbus-1/system-services in addition to all
250 the other well-known locations; note that this should always be /lib,
251 even on platforms where shared libraries on the root FS would go in /lib64,
252 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
253 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
255 • Windows-specific (Ralf Habacker):
256 · fix use of a mutex for autolaunch server detection
257 · don't crash on malloc failure in _dbus_printf_string_upper_bound
259 D-Bus 1.5.4 (2011-06-10)
262 Security (local denial of service):
264 • Byte-swap foreign-endian messages correctly, preventing a long-standing
265 local DoS if foreign-endian messages are relayed through the dbus-daemon
266 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
267 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
271 • The constant to use for an infinite timeout now has a name,
272 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
273 which can be used for source compatibility with older versions of libdbus.
275 • If GLib and DBus-GLib are already installed, more tests will be built,
276 providing better coverage. The new tests can also be installed via
277 ./configure --enable-installed-tests
278 for system integration testing, if required. (fd.o #34570, Simon McVittie)
282 • Consistently use atomic operations for the DBusConnection's refcount,
283 fixing potential threading problems (fd.o #38005, Simon McVittie)
285 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
286 small (300KiB on x86-64) and it frequently doesn't work in unusual
287 toolchains. To optimize for minimum installed size, you should benchmark
288 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
289 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
291 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
292 (fd.o #35880, Timothy Redaelli)
294 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
295 when not using a DESTDIR (fd.o #37870, Simon McVittie)
297 • Windows-specific changes:
298 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
300 D-Bus 1.5.2 (2011-06-01)
303 The "Boar Hunter" release.
305 Notes for distributors:
307 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
308 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
309 toolchain supports it reliably, via something like:
311 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
313 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
317 • D-Bus Specification v0.17
318 · Reserve the extra characters used in signatures by GVariant
319 (fd.o #34529, Simon McVittie)
320 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
321 • Don't force -fPIE: distributions and libtool know better than we do whether
322 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
323 • Allow --disable-gc-sections, in case your toolchain offers the
324 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
325 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
326 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
327 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
328 • Ensure that maintainers upload documentation with the right permissions
329 (fd.o #36130, Simon McVittie)
330 • Don't force users of libdbus to be linked against -lpthread, -lrt
331 (fd.o #32827, Simon McVittie)
332 • Log system-bus activation information to syslog (fd.o #35705,
334 • Log messages dropped due to quotas to syslog (fd.o #35358,
336 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
337 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
338 (fd.o #35228, Lennart Poettering)
339 • In the regression tests, don't report fds as "leaked" if they were open
340 on startup (fd.o #35173, Simon McVittie)
341 • Make dbus-monitor bail out if asked to monitor more than one bus,
342 rather than silently using the last one (fd.o #26548, Will Thompson)
343 • Clarify documentation (fd.o #35182, Simon McVittie)
344 • Clean up minor dead code and some incorrect error handling
345 (fd.o #33128, fd.o #29881; Simon McVittie)
346 • Check that compiler options are supported before using them (fd.o #19681,
349 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
351 D-Bus 1.5.0 (2011-04-11)
354 The "you never know when you need to tow something from your giant
355 flying shark" release.
357 • D-Bus Specification v0.16
358 · Add support for path_namespace and arg0namespace in match rules
359 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
360 · Make argNpath support object paths, not just object-path-like strings,
361 and document it better (fd.o #31818, Will Thompson)
362 • Let the bus daemon implement more than one interface (fd.o #33757,
364 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
366 • Require user intervention to compile with missing 64-bit support
367 (fd.o #35114, Simon McVittie)
368 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
369 • Raise UnknownObject instead of UnknownMethod for calls to methods on
370 paths that are not part of the object tree, and UnknownInterface for calls
371 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
373 D-Bus 1.4.8 (2011-04-08)
376 The "It's like the beginning of a lobster" release.
378 • Rename configure.in to configure.ac, and update it to modern conventions
379 (fd.o #32245; Javier Jardón, Simon McVittie)
380 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
382 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
383 --disable-x11-autolaunch configure option to prevent it altogether
384 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
385 • Install the documentation, and an index for Devhelp (fd.o #13495,
386 Debian #454142; Simon McVittie, Matthias Clasen)
387 • If checks are not disabled, check validity of string-like types and
388 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
389 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
390 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
391 • Break up a huge conditional in config-parser so gcov can produce coverage
392 data (fd.o #10887, Simon McVittie)
393 • List which parts of the Desktop Entry specification are applicable to
394 .service files (fd.o #19159, Sven Herzberg)
395 • Don't suppress service activation if two services have the same Exec=
396 (fd.o #35750, Colin Walters)
398 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
400 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
401 (fd.o #32805, Mark Brand)
403 D-Bus 1.4.6 (2010-02-17)
406 The "1, 2, miss a few, 99, 100" release.
408 • Remove unfinished changes intended to support GTest-based tests,
409 which were mistakenly included in 1.4.4
411 D-Bus 1.4.4 (2010-02-17)
414 • Switch back to using even micro versions for stable releases; 1.4.1
415 should have been called 1.4.2, so skip that version number
416 • Don't leave bad file descriptors being watched when spawning processes,
417 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
418 also LP#656134, LP#680444, LP#713157)
419 • Check for MSG_NOSIGNAL correctly
420 • Fix failure to detect abstract socket support (fd.o #29895)
421 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
422 (fd.o #32262, NB#180486)
423 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,
424 fd.o #33128, fd.o #33277, fd.o #33126, NB#180486)
425 • Avoid possible symlink attacks in /tmp during compilation (fd.o #32854)
426 • Tidy up dead code (fd.o #25306, fd.o #33128, fd.o #34292, NB#180486)
427 • Improve gcc malloc annotations (fd.o #32710)
428 • If the system bus is launched via systemd, protect it from the OOM killer
429 • Documentation improvements (fd.o #11190)

443 · avoid live-lock in Windows CE due to unfair condition variables
445 · support credentials-passing (fd.o #32542)
447 · opt-in to thread safety (fd.o #33464)
449 D-Bus 1.4.1 (20 December 2010)
452 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
453 crash the bus. The existing restriction to 64-levels of nesting previously
454 only applied to the static type signature; now it also applies to dynamic
455 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
457 • OS X portability fixes, including launchd support.
458 • Windows autolaunch improvements.
461 D-Bus 1.4.0 (6 Sep 2010)
