Announcing dbus 1.5.10

[Simon McVittie]

This is a beta or something for dbus-1.6. It changes libdbus' thread
support, which might actually work now (recursive mutexes turn out to
have been broken since 2006); if you rely on using D-Bus with threads,
particularly on non-Linux, please test.

If you want additional bugs fixed or features included before 1.6,
please provide patches, review my patches (see Bugzilla) and/or respond
to the relevant bugs. In particular, fd.o #39196, #39197 have patches
awaiting review to give dbus-launch more useful semantics, which I'd
really like to land before 1.6.

On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008
Base and SUSv2) is now required.

• D-Bus Specification 0.19:
  · Formally define unique connection names and well-known bus names,
    and document best practices for interface, bus, member and error
    names, and object paths (fd.o #37095, Simon McVittie)
  · Document the search path for session and system services on Unix,
    and where they should be installed by build systems (fd.o #21620,
    fd.o #35306; Simon McVittie)
  · Document the systemd transport (fd.o #35232, Lennart Poettering)

• Make dbus_threads_init() use the same built-in threading
  implementation as dbus_threads_init_default(); the user-specified
  primitives that it takes as a parameter are now ignored
  (fd.o #43744, Simon McVittie)

• Allow all configured auth mechanisms, not just one (fd.o #45106,
  Pavel Strashkin)

• Improve cmake build system (Ralf Habacker):
  · simplify XML parser dependencies (fd.o #41027)
  · generate build timestamp (fd.o #41029)
  · only create batch files on Windows
  · fix option and cache syntax
  · add help-options target
  · share dbus-arch-deps.h.in with autotools rather than having our
    own version (fd.o #41033)

• Build tests successfully with older GLib, as found in e.g. Debian 6
  (fd.o #41219, Simon McVittie)

• Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)

• Build documentation correctly if man2html doesn't support filenames on
  its command-line (fd.o #43875, Jack Nagel)

• Improve test coverage. To get even more coverage, run the tests with
  DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)

• Reduce the size of the shared library by moving functionality
  only used by dbus-daemon, tests etc. into their internal library
  and deleting unused code (fd.o #34976, #39759; Simon McVittie)

• Add dbus-daemon --nopidfile option, overriding the configuration, for
  setups where the default configuration must include <pidfile/> to
  avoid breaking traditional init, but the pid file is in fact
  unnecessary; use it under systemd to improve startup time a bit
  (fd.o #45520, Lennart Poettering)

• Optionally (if configured --with-valgrind) add instrumentation to
  debug libdbus and associated tools more meaningfully under Valgrind
  (fd.o #37286, Simon McVittie)

• Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)

• Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)

• If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the
  environment, abort on failure to malloc() (like GLib does), to turn
  runaway memory leaks into a debuggable core-dump if a resource
  limit is applied (fd.o #41048, Simon McVittie)

• Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
  Simon McVittie)

• Unix-specific:
  · Replace our broken reimplementation of recursive mutexes, which has
    been broken since 2006, with an ordinary pthreads recursive mutex
    (fd.o #43744; Sigmund Augdal, Simon McVittie)
  · Use epoll(7) for a more efficient main loop in Linux; equivalent
    patches welcomed for other OSs' equivalents like kqueue, /dev/poll,
    or Solaris event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
  · When running under systemd, use it instead of ConsoleKit to check
    whether to apply at_console policies (fd.o #39609, Lennart
    Poettering)
  · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
  · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258,
    eXeC001er)
  · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make
    installcheck' (fd.o #41218, Simon McVittie)
  · Stop pretending we respect XDG_DATA_DIRS for system services:
    the launch helper doesn't obey environment variables to avoid
    privilege escalation attacks, so make the system bus follow the
    same rules (fd.o #21620, Simon McVittie)

• Windows-specific:
  · Find the dbus-daemon executable next to the shared library
    (fd.o #41558; Jesper Dam, Ralf Habacker)
  · Remove the faulty implementation of _dbus_condvar_wake_all
    (fd.o #44609, Simon McVittie)
