27 Jesper Dam, Ralf Habacker)
29 D-Bus 1.5.8 (2011-09-21)
32 The "cross-metering" release.
34 In addition to dead code removal and refactoring, this release contains all
35 of the bugfixes from 1.4.16.
37 • Clean up dead code, and make more warnings fatal in development builds
38 (fd.o #39231, fd.o #41012; Simon McVittie)
40 • If full test coverage is requested via --enable-tests, strictly require
41 Python, pygobject and dbus-python, which are required by some tests; if not,
42 and Python is missing, skip those tests rather than failing
43 (fd.o #37847, Simon McVittie)
45 • When using cmake, provide the same version-info API in the installed headers
46 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
48 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
50 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
52 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,

61 a service file entry for activation (fd.o #39230, Simon McVittie)
64 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
65 Brian Cameron, Simon McVittie)
66 · On systems that use libcap-ng but not systemd, drop supplemental groups
67 when switching to the daemon user (Red Hat #726953, Steve Grubb)
68 · Make the cmake build work again on GNU platforms (fd.o #29228,
70 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
71 like Solaris (fd.o #40313, Dagobert Michelsen)
72 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
73 (fd.o #40235, Simon McVittie)
74 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
75 (fd.o #39987, Simon McVittie)
76 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
77 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
80 · Fix compilation on MSVC, which doesn't understand "inline" with its
81 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)

83 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
85 D-Bus 1.5.6 (2011-07-29)
88 The "weird, gravy-like aftertaste" release.
90 In addition to new features and refactoring, this release contains all of the
93 Potentially incompatible (Bustle and similar debugging tools will need
94 changes to work as intended):
96 • Do not allow match rules to "eavesdrop" (receive messages intended for a
97 different recipient) by mistake: eavesdroppers must now opt-in to this
98 behaviour by putting "eavesdrop='true'" in the match rule, which will
99 not have any practical effect on buses where eavesdropping is not allowed
100 (fd.o #37890, Cosimo Alfarano)
104 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
105 Cosimo Alfarano, Simon McVittie)
106 · add the "eavesdrop" keyword to match rules
107 · define eavesdropping, unicast messages and broadcast messages
108 · stop claiming that match rules are needed to match unicast messages to you
109 · promote the type system to be a top-level section
111 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
112 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
113 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
115 • Consistently use atomic operations on everything that is ever manipulated
116 via atomic ops, as was done for changes to DBusConnection's refcount in
117 1.4.12 (fd.o #38005, Simon McVittie)
119 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
122 • Make "make check" in a clean tree work, by not running tests until
123 test data has been set up (fd.o #34405, Simon McVittie)
125 • The dbus-daemon no longer busy-loops if it has a very large number of file
126 descriptors (fd.o #23194, Simon McVittie)
128 • Refactor message flow through dispatching to avoid locking violations if
129 the bus daemon's message limit is hit; remove the per-connection link cache,
130 which was meant to improve performance, but now reduces it (fd.o #34393,
133 • Some cmake fixes (Ralf Habacker)
135 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
136 Simon McVittie, Lennart Poettering)
138 • Stop storing two extra byte order indicators in each D-Bus message
139 (fd.o #38287, Simon McVittie)
141 • Add an optional Stats interface which can be used to get statistics from
142 a running dbus-daemon if enabled at configure time with --enable-stats
143 (fd.o #34040, Simon McVittie)
145 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
147 • Documentation (fd.o #36156, Simon McVittie):
148 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
149 · install more documentation automatically, including man2html output
150 · put dbus.devhelp in the right place (it must go in ${htmldir})
153 · look for system services in /lib/dbus-1/system-services in addition to all
154 the other well-known locations; note that this should always be /lib,
155 even on platforms where shared libraries on the root FS would go in /lib64,
156 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
157 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
159 • Windows-specific (Ralf Habacker):
160 · fix use of a mutex for autolaunch server detection
161 · don't crash on malloc failure in _dbus_printf_string_upper_bound
163 D-Bus 1.5.4 (2011-06-10)
166 Security (local denial of service):
168 • Byte-swap foreign-endian messages correctly, preventing a long-standing
169 local DoS if foreign-endian messages are relayed through the dbus-daemon
170 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
171 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
175 • The constant to use for an infinite timeout now has a name,
176 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
177 which can be used for source compatibility with older versions of libdbus.
179 • If GLib and DBus-GLib are already installed, more tests will be built,
180 providing better coverage. The new tests can also be installed via
181 ./configure --enable-installed-tests
182 for system integration testing, if required. (fd.o #34570, Simon McVittie)
186 • Consistently use atomic operations for the DBusConnection's refcount,
187 fixing potential threading problems (fd.o #38005, Simon McVittie)
189 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
190 small (300KiB on x86-64) and it frequently doesn't work in unusual
191 toolchains. To optimize for minimum installed size, you should benchmark
192 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
193 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
195 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
196 (fd.o #35880, Timothy Redaelli)
198 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
199 when not using a DESTDIR (fd.o #37870, Simon McVittie)
201 • Windows-specific changes:
202 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
204 D-Bus 1.5.2 (2011-06-01)
207 The "Boar Hunter" release.
209 Notes for distributors:
211 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
212 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
213 toolchain supports it reliably, via something like:
215 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
217 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
221 • D-Bus Specification v0.17
222 · Reserve the extra characters used in signatures by GVariant
223 (fd.o #34529, Simon McVittie)
224 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
225 • Don't force -fPIE: distributions and libtool know better than we do whether
226 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
227 • Allow --disable-gc-sections, in case your toolchain offers the
228 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
229 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
230 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
231 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
232 • Ensure that maintainers upload documentation with the right permissions
233 (fd.o #36130, Simon McVittie)
234 • Don't force users of libdbus to be linked against -lpthread, -lrt
235 (fd.o #32827, Simon McVittie)
236 • Log system-bus activation information to syslog (fd.o #35705,
238 • Log messages dropped due to quotas to syslog (fd.o #35358,
240 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
241 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
242 (fd.o #35228, Lennart Poettering)
243 • In the regression tests, don't report fds as "leaked" if they were open
244 on startup (fd.o #35173, Simon McVittie)
245 • Make dbus-monitor bail out if asked to monitor more than one bus,
246 rather than silently using the last one (fd.o #26548, Will Thompson)
247 • Clarify documentation (fd.o #35182, Simon McVittie)
248 • Clean up minor dead code and some incorrect error handling
249 (fd.o #33128, fd.o #29881; Simon McVittie)
250 • Check that compiler options are supported before using them (fd.o #19681,
253 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
255 D-Bus 1.5.0 (2011-04-11)
258 The "you never know when you need to tow something from your giant
259 flying shark" release.
261 • D-Bus Specification v0.16
262 · Add support for path_namespace and arg0namespace in match rules
263 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
264 · Make argNpath support object paths, not just object-path-like strings,
265 and document it better (fd.o #31818, Will Thompson)
266 • Let the bus daemon implement more than one interface (fd.o #33757,
268 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
270 • Require user intervention to compile with missing 64-bit support
271 (fd.o #35114, Simon McVittie)
272 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
273 • Raise UnknownObject instead of UnknownMethod for calls to methods on
274 paths that are not part of the object tree, and UnknownInterface for calls
275 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
277 D-Bus 1.4.8 (2011-04-08)
280 The "It's like the beginning of a lobster" release.
282 • Rename configure.in to configure.ac, and update it to modern conventions
283 (fd.o #32245; Javier Jardón, Simon McVittie)
284 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
286 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
287 --disable-x11-autolaunch configure option to prevent it altogether
288 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
289 • Install the documentation, and an index for Devhelp (fd.o #13495,
290 Debian #454142; Simon McVittie, Matthias Clasen)
291 • If checks are not disabled, check validity of string-like types and
292 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
293 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
294 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
295 • Break up a huge conditional in config-parser so gcov can produce coverage
296 data (fd.o #10887, Simon McVittie)
297 • List which parts of the Desktop Entry specification are applicable to
298 .service files (fd.o #19159, Sven Herzberg)
299 • Don't suppress service activation if two services have the same Exec=
300 (fd.o #35750, Colin Walters)
302 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
304 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
305 (fd.o #32805, Mark Brand)
307 D-Bus 1.4.6 (2010-02-17)
310 The "1, 2, miss a few, 99, 100" release.
312 • Remove unfinished changes intended to support GTest-based tests,
313 which were mistakenly included in 1.4.4
315 D-Bus 1.4.4 (2010-02-17)
318 • Switch back to using even micro versions for stable releases; 1.4.1
319 should have been called 1.4.2, so skip that version number
320 • Don't leave bad file descriptors being watched when spawning processes,
321 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
322 also LP#656134, LP#680444, LP#713157)
323 • Check for MSG_NOSIGNAL correctly
324 • Fix failure to detect abstract socket support (fd.o #29895)
325 • Make _dbus_system_logv actually exit with DBUS_SYSTEM_LOG_FATAL

356 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
357 crash the bus. The existing restriction to 64-levels of nesting previously
358 only applied to the static type signature; now it also applies to dynamic
359 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
361 • OS X portability fixes, including launchd support.
362 • Windows autolaunch improvements.
