1 D-Bus 1.5.6 (UNRELEASED)
4 Potentially incompatible (Bustle and similar debugging tools will need
5 changes to work as intended):
7 • Do not allow match rules to "eavesdrop" (receive messages intended for a
8 different recipient) by mistake: eavesdroppers must now opt-in to this
9 behaviour by putting "eavesdrop='true'" in the match rule, which will
10 not have any practical effect on buses where eavesdropping is not allowed
11 (fd.o #37890, Cosimo Alfarano)
15 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
16 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
17 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
19 • Consistently use atomic operations on the refcounts of DBusPendingCall
20 and DBusServer, as was done for DBusConnection in 1.4.12 (fd.o #38005,
23 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
26 • Make "make check" in a clean tree work, by not running tests until
27 test data has been set up (fd.o #34405, Simon McVittie)
29 • The dbus-daemon no longer busy-loops if it has a very large number of file
30 descriptors (fd.o #23194, Simon McVittie)
32 • Some cmake fixes (Ralf Habacker)
34 • Remove dead code, mainly from DBusString (fd.o #38570, Simon McVittie)
36 • Stop storing two extra byte order indicators in each D-Bus message
37 (fd.o #38287, Simon McVittie)
39 • Add an optional Stats interface which can be used to get statistics from
40 a running dbus-daemon if enabled at configure time with --enable-stats
41 (fd.o #34040, Simon McVittie)
43 • Documentation (fd.o #36156, Simon McVittie):
44 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
45 · install more documentation automatically, including man2html output
46 · put dbus.devhelp in the right place (it must go in ${htmldir})
48 • Unix-specific (fd.o #33465, Simon McVittie):
49 · opt-in to fd passing on Solaris
51 • Windows-specific (Ralf Habacker):
52 · fix use of a mutex for autolaunch server detection
53 · don't crash on malloc failure in _dbus_printf_string_upper_bound
55 D-Bus 1.5.4 (2011-06-10)
58 Security (local denial of service):
60 • Byte-swap foreign-endian messages correctly, preventing a long-standing
61 local DoS if foreign-endian messages are relayed through the dbus-daemon
62 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
63 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
67 • The constant to use for an infinite timeout now has a name,
68 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
69 which can be used for source compatibility with older versions of libdbus.
71 • If GLib and DBus-GLib are already installed, more tests will be built,
72 providing better coverage. The new tests can also be installed via
73 ./configure --enable-installed-tests
74 for system integration testing, if required. (fd.o #34570, Simon McVittie)
78 • Consistently use atomic operations for the DBusConnection's refcount,
79 fixing potential threading problems (fd.o #38005, Simon McVittie)
81 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
82 small (300KiB on x86-64) and it frequently doesn't work in unusual
83 toolchains. To optimize for minimum installed size, you should benchmark
84 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
85 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
87 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
88 (fd.o #35880, Timothy Redaelli)
90 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
91 when not using a DESTDIR (fd.o #37870, Simon McVittie)
93 • Windows-specific changes:
94 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
96 D-Bus 1.5.2 (2011-06-01)
99 The "Boar Hunter" release.
101 Notes for distributors:
103 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
104 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
105 toolchain supports it reliably, via something like:
107 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
109 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
113 • D-Bus Specification v0.17

115 (fd.o #34529, Simon McVittie)
116 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
117 • Don't force -fPIE: distributions and libtool know better than we do whether
118 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
119 • Allow --disable-gc-sections, in case your toolchain offers the
120 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
121 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
122 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
123 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
124 • Ensure that maintainers upload documentation with the right permissions
125 (fd.o #36130, Simon McVittie)

133 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
134 (fd.o #35228, Lennart Poettering)
135 • In the regression tests, don't report fds as "leaked" if they were open
136 on startup (fd.o #35173, Simon McVittie)
137 • Make dbus-monitor bail out if asked to monitor more than one bus,
138 rather than silently using the last one (fd.o #26548, Will Thompson)
139 • Clarify documentation (fd.o #35182, Simon McVittie)
140 • Clean up minor dead code and some incorrect error handling

155 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
156 · Make argNpath support object paths, not just object-path-like strings,
157 and document it better (fd.o #31818, Will Thompson)
158 • Let the bus daemon implement more than one interface (fd.o #33757,
160 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
162 • Require user intervention to compile with missing 64-bit support
163 (fd.o #35114, Simon McVittie)
164 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
165 • Raise UnknownObject instead of UnknownMethod for calls to methods on
166 paths that are not part of the object tree, and UnknownInterface for calls
167 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)

172 The "It's like the beginning of a lobster" release.

176 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
178 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
179 --disable-x11-autolaunch configure option to prevent it altogether
180 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
181 • Install the documentation, and an index for Devhelp (fd.o #13495,
182 Debian #454142; Simon McVittie, Matthias Clasen)
183 • If checks are not disabled, check validity of string-like types and
184 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
185 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
186 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
187 • Break up a huge conditional in config-parser so gcov can produce coverage
188 data (fd.o #10887, Simon McVittie)
189 • List which parts of the Desktop Entry specification are applicable to
190 .service files (fd.o #19159, Sven Herzberg)
191 • Don't suppress service activation if two services have the same Exec=
192 (fd.o #35750, Colin Walters)
194 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
196 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
197 (fd.o #32805, Mark Brand)

202 The "1, 2, miss a few, 99, 100" release.
204 • Remove unfinished changes intended to support GTest-based tests,
205 which were mistakenly included in 1.4.4
207 D-Bus 1.4.4 (2010-02-17)
210 • Switch back to using even micro versions for stable releases; 1.4.1
211 should have been called 1.4.2, so skip that version number
212 • Don't leave bad file descriptors being watched when spawning processes,
213 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
214 also LP#656134, LP#680444, LP#713157)
215 • Check for MSG_NOSIGNAL correctly

220 fd.o #33128, fd.o #33277, fd.o #33126, NB#180486)

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