1 D-Bus 1.5.11 (UNRELEASED)
4 • Add public API to validate various string types:
5 dbus_validate_path(), dbus_validate_interface(), dbus_validate_member(),
6 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
7 (fd.o #39549, Simon McVittie)
9 • Turn DBusBasicValue into public API so bindings don't need to invent their
10 own "union of everything" type (fd.o #11191, Simon McVittie)
13 · make dbus-daemon.exe --print-address (and --print-pid) work again
14 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
16 D-Bus 1.5.10 (2012-02-21)
19 The "fire in Delerium" release.
21 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
22 and SUSv2) is now required.
24 • D-Bus Specification 0.19:
25 · Formally define unique connection names and well-known bus names,
26 and document best practices for interface, bus, member and error names,
27 and object paths (fd.o #37095, Simon McVittie)
28 · Document the search path for session and system services on Unix, and
29 where they should be installed by build systems (fd.o #21620, fd.o #35306;
31 · Document the systemd transport (fd.o #35232, Lennart Poettering)
33 • Make dbus_threads_init() use the same built-in threading implementation
34 as dbus_threads_init_default(); the user-specified primitives that it
35 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
37 • Allow all configured auth mechanisms, not just one (fd.o #45106,
40 • Improve cmake build system (Ralf Habacker):
41 · simplify XML parser dependencies (fd.o #41027)
42 · generate build timestamp (fd.o #41029)
43 · only create batch files on Windows
44 · fix option and cache syntax
45 · add help-options target
46 · share dbus-arch-deps.h.in with autotools rather than having our
47 own version (fd.o #41033)
49 • Build tests successfully with older GLib, as found in e.g. Debian 6
50 (fd.o #41219, Simon McVittie)
52 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
54 • Build documentation correctly if man2html doesn't support filenames on
55 its command-line (fd.o #43875, Jack Nagel)
57 • Improve test coverage. To get even more coverage, run the tests with
58 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
60 • Reduce the size of the shared library by moving functionality only used
61 by dbus-daemon, tests etc. into their internal library and deleting
62 unused code (fd.o #34976, #39759; Simon McVittie)
64 • Add dbus-daemon --nopidfile option, overriding the configuration, for
65 setups where the default configuration must include <pidfile/> to avoid
66 breaking traditional init, but the pid file is in fact unnecessary; use
67 it under systemd to improve startup time a bit (fd.o #45520,
70 • Optionally (if configured --with-valgrind) add instrumentation to debug
71 libdbus and associated tools more meaningfully under Valgrind
72 (fd.o #37286, Simon McVittie)
74 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
76 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
78 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
79 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
80 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
83 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
87 · Replace our broken reimplementation of recursive mutexes, which has
88 been broken since 2006, with an ordinary pthreads recursive mutex
89 (fd.o #43744; Sigmund Augdal, Simon McVittie)
90 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
91 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
92 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
93 · When running under systemd, use it instead of ConsoleKit to check
94 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
95 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
96 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
97 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
98 (fd.o #41218, Simon McVittie)
99 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
100 helper doesn't obey environment variables to avoid privilege escalation
101 attacks, so make the system bus follow the same rules
102 (fd.o #21620, Simon McVittie)
105 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
106 Jesper Dam, Ralf Habacker)
107 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
110 D-Bus 1.5.8 (2011-09-21)
113 The "cross-metering" release.
115 In addition to dead code removal and refactoring, this release contains all
116 of the bugfixes from 1.4.16.
118 • Clean up dead code, and make more warnings fatal in development builds
119 (fd.o #39231, fd.o #41012; Simon McVittie)
121 • If full test coverage is requested via --enable-tests, strictly require
122 Python, pygobject and dbus-python, which are required by some tests; if not,
123 and Python is missing, skip those tests rather than failing
124 (fd.o #37847, Simon McVittie)
126 • When using cmake, provide the same version-info API in the installed headers
127 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
129 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
131 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
133 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
136 • Fix duplicates in authors list (Ralf Habacker)
138 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
139 (fd.o #39879, Chris Mayo)
141 • Fix a small memory leak, and a failure to report errors, when updating
142 a service file entry for activation (fd.o #39230, Simon McVittie)
145 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
146 Brian Cameron, Simon McVittie)
147 · On systems that use libcap-ng but not systemd, drop supplemental groups
148 when switching to the daemon user (Red Hat #726953, Steve Grubb)
149 · Make the cmake build work again on GNU platforms (fd.o #29228,
151 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
152 like Solaris (fd.o #40313, Dagobert Michelsen)
153 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
154 (fd.o #40235, Simon McVittie)
155 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
156 (fd.o #39987, Simon McVittie)
157 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
158 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
161 · Fix compilation on MSVC, which doesn't understand "inline" with its
162 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
163 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
164 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
166 D-Bus 1.5.6 (2011-07-29)
169 The "weird, gravy-like aftertaste" release.
171 In addition to new features and refactoring, this release contains all of the
172 bugfixes from 1.4.14.
174 Potentially incompatible (Bustle and similar debugging tools will need
175 changes to work as intended):
177 • Do not allow match rules to "eavesdrop" (receive messages intended for a
178 different recipient) by mistake: eavesdroppers must now opt-in to this
179 behaviour by putting "eavesdrop='true'" in the match rule, which will
180 not have any practical effect on buses where eavesdropping is not allowed
181 (fd.o #37890, Cosimo Alfarano)
185 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
186 Cosimo Alfarano, Simon McVittie)
187 · add the "eavesdrop" keyword to match rules
188 · define eavesdropping, unicast messages and broadcast messages
189 · stop claiming that match rules are needed to match unicast messages to you
190 · promote the type system to be a top-level section
192 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
193 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
194 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
196 • Consistently use atomic operations on everything that is ever manipulated
197 via atomic ops, as was done for changes to DBusConnection's refcount in
198 1.4.12 (fd.o #38005, Simon McVittie)
200 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
203 • Make "make check" in a clean tree work, by not running tests until
204 test data has been set up (fd.o #34405, Simon McVittie)
206 • The dbus-daemon no longer busy-loops if it has a very large number of file
207 descriptors (fd.o #23194, Simon McVittie)
209 • Refactor message flow through dispatching to avoid locking violations if
210 the bus daemon's message limit is hit; remove the per-connection link cache,
211 which was meant to improve performance, but now reduces it (fd.o #34393,
214 • Some cmake fixes (Ralf Habacker)
216 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
217 Simon McVittie, Lennart Poettering)
219 • Stop storing two extra byte order indicators in each D-Bus message
220 (fd.o #38287, Simon McVittie)
222 • Add an optional Stats interface which can be used to get statistics from
223 a running dbus-daemon if enabled at configure time with --enable-stats
224 (fd.o #34040, Simon McVittie)
226 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
228 • Documentation (fd.o #36156, Simon McVittie):
229 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
230 · install more documentation automatically, including man2html output
231 · put dbus.devhelp in the right place (it must go in ${htmldir})
234 · look for system services in /lib/dbus-1/system-services in addition to all
235 the other well-known locations; note that this should always be /lib,
236 even on platforms where shared libraries on the root FS would go in /lib64,
237 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
238 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
240 • Windows-specific (Ralf Habacker):
241 · fix use of a mutex for autolaunch server detection
242 · don't crash on malloc failure in _dbus_printf_string_upper_bound
244 D-Bus 1.5.4 (2011-06-10)
247 Security (local denial of service):
249 • Byte-swap foreign-endian messages correctly, preventing a long-standing
250 local DoS if foreign-endian messages are relayed through the dbus-daemon
251 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
252 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
256 • The constant to use for an infinite timeout now has a name,
257 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
258 which can be used for source compatibility with older versions of libdbus.
260 • If GLib and DBus-GLib are already installed, more tests will be built,
261 providing better coverage. The new tests can also be installed via
262 ./configure --enable-installed-tests
263 for system integration testing, if required. (fd.o #34570, Simon McVittie)
267 • Consistently use atomic operations for the DBusConnection's refcount,
268 fixing potential threading problems (fd.o #38005, Simon McVittie)
270 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
271 small (300KiB on x86-64) and it frequently doesn't work in unusual
272 toolchains. To optimize for minimum installed size, you should benchmark
273 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
274 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
276 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
277 (fd.o #35880, Timothy Redaelli)
279 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
280 when not using a DESTDIR (fd.o #37870, Simon McVittie)
282 • Windows-specific changes:
283 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
285 D-Bus 1.5.2 (2011-06-01)
288 The "Boar Hunter" release.
290 Notes for distributors:
292 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
293 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
294 toolchain supports it reliably, via something like:
296 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
298 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
302 • D-Bus Specification v0.17
303 · Reserve the extra characters used in signatures by GVariant
304 (fd.o #34529, Simon McVittie)
305 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
306 • Don't force -fPIE: distributions and libtool know better than we do whether
307 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
308 • Allow --disable-gc-sections, in case your toolchain offers the
309 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
310 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
311 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
312 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
313 • Ensure that maintainers upload documentation with the right permissions
314 (fd.o #36130, Simon McVittie)
315 • Don't force users of libdbus to be linked against -lpthread, -lrt
316 (fd.o #32827, Simon McVittie)
317 • Log system-bus activation information to syslog (fd.o #35705,
319 • Log messages dropped due to quotas to syslog (fd.o #35358,
321 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
322 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
323 (fd.o #35228, Lennart Poettering)
324 • In the regression tests, don't report fds as "leaked" if they were open
325 on startup (fd.o #35173, Simon McVittie)
326 • Make dbus-monitor bail out if asked to monitor more than one bus,
327 rather than silently using the last one (fd.o #26548, Will Thompson)
328 • Clarify documentation (fd.o #35182, Simon McVittie)
329 • Clean up minor dead code and some incorrect error handling
330 (fd.o #33128, fd.o #29881; Simon McVittie)

339 The "you never know when you need to tow something from your giant
340 flying shark" release.
342 • D-Bus Specification v0.16
343 · Add support for path_namespace and arg0namespace in match rules
344 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
345 · Make argNpath support object paths, not just object-path-like strings,
346 and document it better (fd.o #31818, Will Thompson)
347 • Let the bus daemon implement more than one interface (fd.o #33757,
349 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
351 • Require user intervention to compile with missing 64-bit support
352 (fd.o #35114, Simon McVittie)
353 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
354 • Raise UnknownObject instead of UnknownMethod for calls to methods on
355 paths that are not part of the object tree, and UnknownInterface for calls
356 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
358 D-Bus 1.4.8 (2011-04-08)
361 The "It's like the beginning of a lobster" release.
363 • Rename configure.in to configure.ac, and update it to modern conventions
364 (fd.o #32245; Javier Jardón, Simon McVittie)
365 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
367 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
368 --disable-x11-autolaunch configure option to prevent it altogether
369 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
370 • Install the documentation, and an index for Devhelp (fd.o #13495,
371 Debian #454142; Simon McVittie, Matthias Clasen)
372 • If checks are not disabled, check validity of string-like types and
373 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
374 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
375 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
376 • Break up a huge conditional in config-parser so gcov can produce coverage
377 data (fd.o #10887, Simon McVittie)
378 • List which parts of the Desktop Entry specification are applicable to
379 .service files (fd.o #19159, Sven Herzberg)
380 • Don't suppress service activation if two services have the same Exec=
381 (fd.o #35750, Colin Walters)
383 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
385 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
386 (fd.o #32805, Mark Brand)
388 D-Bus 1.4.6 (2010-02-17)
391 The "1, 2, miss a few, 99, 100" release.
393 • Remove unfinished changes intended to support GTest-based tests,
394 which were mistakenly included in 1.4.4
396 D-Bus 1.4.4 (2010-02-17)
399 • Switch back to using even micro versions for stable releases; 1.4.1
400 should have been called 1.4.2, so skip that version number
401 • Don't leave bad file descriptors being watched when spawning processes,
402 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
403 also LP#656134, LP#680444, LP#713157)
404 • Check for MSG_NOSIGNAL correctly
405 • Fix failure to detect abstract socket support (fd.o #29895)

407 (fd.o #32262, NB#180486)
408 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,
409 fd.o #33128, fd.o #33277, fd.o #33126, NB#180486)
410 • Avoid possible symlink attacks in /tmp during compilation (fd.o #32854)

413 • If the system bus is launched via systemd, protect it from the OOM killer
414 • Documentation improvements (fd.o #11190)

434 D-Bus 1.4.1 (20 December 2010)
437 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
438 crash the bus. The existing restriction to 64-levels of nesting previously
439 only applied to the static type signature; now it also applies to dynamic
440 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
442 • OS X portability fixes, including launchd support.
443 • Windows autolaunch improvements.
446 D-Bus 1.4.0 (6 Sep 2010)

459 - file descriptor passing on Unix socket transports
460 - use of GCC atomic intrinsics for better processor support
461 (requires -march=i486 or above for x86 compilation)
462 - thread-safe FD_CLOEXEC setting on recent Linux kernels (2.6.24-27 and up)
463 and glibc (2.9 for pipe2 and 2.10 for accept4)
