1 D-Bus 1.5.10 (UNRELEASED)
4 • D-Bus Specification 0.19:
5 · Formally define unique connection names and well-known bus names,
6 and document best practices for interface, bus, member and error names,
7 and object paths (fd.o #37095, Simon McVittie)
8 · Document the search path for session and system services on Unix, and
9 where they should be installed by build systems (fd.o #21620, fd.o #35306;
11 · Document the systemd transport (fd.o #35232, Lennart Poettering)
13 • Allow all configured auth mechanisms, not just one (fd.o #45106,
16 • Improve cmake build system (Ralf Habacker):
17 · simplify XML parser dependencies (fd.o #41027)
18 · generate build timestamp (fd.o #41029)
19 · only create batch files on Windows
20 · fix option and cache syntax
21 · add help-options target
22 · share dbus-arch-deps.h.in with autotools rather than having our
23 own version (fd.o #41033)
25 • Build tests successfully with older GLib, as found in e.g. Debian 6
26 (fd.o #41219, Simon McVittie)
28 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
30 • Build documentation correctly if man2html doesn't support filenames on
31 its command-line (fd.o #43875, Jack Nagel)
33 • Improve test coverage. To get even more coverage, run the tests with
34 DBUS_TEST_SLOW=1 (fd.o #38285, Simon McVittie)
36 • Reduce the size of the shared library by moving functionality only used
37 by dbus-daemon, tests etc. into their internal library and deleting
38 unused code (fd.o #34976, #39759; Simon McVittie)
40 • Add dbus-daemon --nopidfile option, overriding the configuration, for
41 setups where the default configuration must include <pidfile/> to avoid
42 breaking traditional init, but the pid file is in fact unnecessary; use
43 it under systemd to improve startup time a bit (fd.o #45520,
46 • Optionally (if configured --with-valgrind) add instrumentation to debug
47 libdbus and associated tools more meaningfully under Valgrind
48 (fd.o #37286, Simon McVittie)
50 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
52 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
55 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
56 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
57 event ports (fd.o #33337, Simon McVittie)
58 · When running under systemd, use it instead of ConsoleKit to check
59 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
60 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
61 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
62 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
63 (fd.o #41218, Simon McVittie)
64 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
65 helper doesn't obey environment variables to avoid privilege escalation
66 attacks, so make the system bus follow the same rules
67 (fd.o #21620, Simon McVittie)
70 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
71 Jesper Dam, Ralf Habacker)
73 D-Bus 1.5.8 (2011-09-21)
76 The "cross-metering" release.
78 In addition to dead code removal and refactoring, this release contains all
79 of the bugfixes from 1.4.16.
81 • Clean up dead code, and make more warnings fatal in development builds
82 (fd.o #39231, fd.o #41012; Simon McVittie)
84 • If full test coverage is requested via --enable-tests, strictly require
85 Python, pygobject and dbus-python, which are required by some tests; if not,
86 and Python is missing, skip those tests rather than failing
87 (fd.o #37847, Simon McVittie)
89 • When using cmake, provide the same version-info API in the installed headers
90 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
92 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
94 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
96 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
99 • Fix duplicates in authors list (Ralf Habacker)
101 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
102 (fd.o #39879, Chris Mayo)
104 • Fix a small memory leak, and a failure to report errors, when updating
105 a service file entry for activation (fd.o #39230, Simon McVittie)
108 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
109 Brian Cameron, Simon McVittie)
110 · On systems that use libcap-ng but not systemd, drop supplemental groups
111 when switching to the daemon user (Red Hat #726953, Steve Grubb)
112 · Make the cmake build work again on GNU platforms (fd.o #29228,
114 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
115 like Solaris (fd.o #40313, Dagobert Michelsen)
116 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
117 (fd.o #40235, Simon McVittie)
118 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
119 (fd.o #39987, Simon McVittie)
120 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
121 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
124 · Fix compilation on MSVC, which doesn't understand "inline" with its
125 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
126 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
127 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
129 D-Bus 1.5.6 (2011-07-29)
132 The "weird, gravy-like aftertaste" release.
134 In addition to new features and refactoring, this release contains all of the
135 bugfixes from 1.4.14.
137 Potentially incompatible (Bustle and similar debugging tools will need
138 changes to work as intended):
140 • Do not allow match rules to "eavesdrop" (receive messages intended for a
141 different recipient) by mistake: eavesdroppers must now opt-in to this
142 behaviour by putting "eavesdrop='true'" in the match rule, which will
143 not have any practical effect on buses where eavesdropping is not allowed
144 (fd.o #37890, Cosimo Alfarano)
148 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
149 Cosimo Alfarano, Simon McVittie)
150 · add the "eavesdrop" keyword to match rules
151 · define eavesdropping, unicast messages and broadcast messages
152 · stop claiming that match rules are needed to match unicast messages to you
153 · promote the type system to be a top-level section
155 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
156 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
157 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
159 • Consistently use atomic operations on everything that is ever manipulated
160 via atomic ops, as was done for changes to DBusConnection's refcount in
161 1.4.12 (fd.o #38005, Simon McVittie)
163 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
166 • Make "make check" in a clean tree work, by not running tests until
167 test data has been set up (fd.o #34405, Simon McVittie)
169 • The dbus-daemon no longer busy-loops if it has a very large number of file
170 descriptors (fd.o #23194, Simon McVittie)
172 • Refactor message flow through dispatching to avoid locking violations if
173 the bus daemon's message limit is hit; remove the per-connection link cache,
174 which was meant to improve performance, but now reduces it (fd.o #34393,
177 • Some cmake fixes (Ralf Habacker)
179 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
180 Simon McVittie, Lennart Poettering)
182 • Stop storing two extra byte order indicators in each D-Bus message
183 (fd.o #38287, Simon McVittie)
185 • Add an optional Stats interface which can be used to get statistics from
186 a running dbus-daemon if enabled at configure time with --enable-stats
187 (fd.o #34040, Simon McVittie)
189 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
191 • Documentation (fd.o #36156, Simon McVittie):
192 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
193 · install more documentation automatically, including man2html output
194 · put dbus.devhelp in the right place (it must go in ${htmldir})
197 · look for system services in /lib/dbus-1/system-services in addition to all
198 the other well-known locations; note that this should always be /lib,
199 even on platforms where shared libraries on the root FS would go in /lib64,
200 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
201 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
203 • Windows-specific (Ralf Habacker):
204 · fix use of a mutex for autolaunch server detection
205 · don't crash on malloc failure in _dbus_printf_string_upper_bound
207 D-Bus 1.5.4 (2011-06-10)
210 Security (local denial of service):
212 • Byte-swap foreign-endian messages correctly, preventing a long-standing
213 local DoS if foreign-endian messages are relayed through the dbus-daemon
214 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
215 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
219 • The constant to use for an infinite timeout now has a name,
220 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
221 which can be used for source compatibility with older versions of libdbus.
223 • If GLib and DBus-GLib are already installed, more tests will be built,
224 providing better coverage. The new tests can also be installed via
225 ./configure --enable-installed-tests
226 for system integration testing, if required. (fd.o #34570, Simon McVittie)
230 • Consistently use atomic operations for the DBusConnection's refcount,
231 fixing potential threading problems (fd.o #38005, Simon McVittie)
233 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
234 small (300KiB on x86-64) and it frequently doesn't work in unusual
235 toolchains. To optimize for minimum installed size, you should benchmark
236 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
237 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
239 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
240 (fd.o #35880, Timothy Redaelli)
242 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
243 when not using a DESTDIR (fd.o #37870, Simon McVittie)
245 • Windows-specific changes:
246 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
248 D-Bus 1.5.2 (2011-06-01)
251 The "Boar Hunter" release.
253 Notes for distributors:
255 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
256 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
257 toolchain supports it reliably, via something like:
259 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
261 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
265 • D-Bus Specification v0.17
266 · Reserve the extra characters used in signatures by GVariant
267 (fd.o #34529, Simon McVittie)
268 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
269 • Don't force -fPIE: distributions and libtool know better than we do whether
270 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
271 • Allow --disable-gc-sections, in case your toolchain offers the
272 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
273 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
274 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
275 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
276 • Ensure that maintainers upload documentation with the right permissions
277 (fd.o #36130, Simon McVittie)
278 • Don't force users of libdbus to be linked against -lpthread, -lrt
279 (fd.o #32827, Simon McVittie)
280 • Log system-bus activation information to syslog (fd.o #35705,
282 • Log messages dropped due to quotas to syslog (fd.o #35358,
284 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
285 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
286 (fd.o #35228, Lennart Poettering)
287 • In the regression tests, don't report fds as "leaked" if they were open
288 on startup (fd.o #35173, Simon McVittie)
289 • Make dbus-monitor bail out if asked to monitor more than one bus,
290 rather than silently using the last one (fd.o #26548, Will Thompson)
291 • Clarify documentation (fd.o #35182, Simon McVittie)
292 • Clean up minor dead code and some incorrect error handling
293 (fd.o #33128, fd.o #29881; Simon McVittie)
294 • Check that compiler options are supported before using them (fd.o #19681,
297 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
299 D-Bus 1.5.0 (2011-04-11)
302 The "you never know when you need to tow something from your giant
303 flying shark" release.
305 • D-Bus Specification v0.16
306 · Add support for path_namespace and arg0namespace in match rules
307 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
308 · Make argNpath support object paths, not just object-path-like strings,
309 and document it better (fd.o #31818, Will Thompson)
310 • Let the bus daemon implement more than one interface (fd.o #33757,
312 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
314 • Require user intervention to compile with missing 64-bit support
315 (fd.o #35114, Simon McVittie)
316 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
317 • Raise UnknownObject instead of UnknownMethod for calls to methods on
318 paths that are not part of the object tree, and UnknownInterface for calls
319 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
321 D-Bus 1.4.8 (2011-04-08)
324 The "It's like the beginning of a lobster" release.
326 • Rename configure.in to configure.ac, and update it to modern conventions
327 (fd.o #32245; Javier Jardón, Simon McVittie)
328 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
330 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
331 --disable-x11-autolaunch configure option to prevent it altogether
332 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
333 • Install the documentation, and an index for Devhelp (fd.o #13495,
334 Debian #454142; Simon McVittie, Matthias Clasen)
335 • If checks are not disabled, check validity of string-like types and
336 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
337 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
338 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
339 • Break up a huge conditional in config-parser so gcov can produce coverage
340 data (fd.o #10887, Simon McVittie)
341 • List which parts of the Desktop Entry specification are applicable to
342 .service files (fd.o #19159, Sven Herzberg)
343 • Don't suppress service activation if two services have the same Exec=
344 (fd.o #35750, Colin Walters)
346 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
348 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
349 (fd.o #32805, Mark Brand)
351 D-Bus 1.4.6 (2010-02-17)
354 The "1, 2, miss a few, 99, 100" release.
356 • Remove unfinished changes intended to support GTest-based tests,
357 which were mistakenly included in 1.4.4
359 D-Bus 1.4.4 (2010-02-17)
362 • Switch back to using even micro versions for stable releases; 1.4.1
363 should have been called 1.4.2, so skip that version number
364 • Don't leave bad file descriptors being watched when spawning processes,
365 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
366 also LP#656134, LP#680444, LP#713157)
367 • Check for MSG_NOSIGNAL correctly
368 • Fix failure to detect abstract socket support (fd.o #29895)
369 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL
370 (fd.o #32262, NB#180486)
371 • Improve some error code paths (fd.o #29981, fd.o #32264, fd.o #32262,
372 fd.o #33128, fd.o #33277, fd.o #33126, NB#180486)

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