Announcing D-Bus 1.9.0

[Simon McVittie]

The “tiered cheeses” release.

It's about time we started releasing the new unstable branch. This is
the first development release for the 1.9.x branch leading to a future
1.10.0 stable release, and probably has exciting new bugs. Try it if you
like to live on the edge.

git tag: dbus-1.9.0

Requirements:

• Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
  requires either the libsystemd or libsd-daemon shared library,
  dropping the embedded convenience copy of sd-daemon
  (fd.o #71818, Simon)

Build-time configuration changes:

• The Stats interface is now enabled by default, and locked-down to
  root-only on the system bus. Configure with --disable-stats
  to disable it altogether on memory- or disk-constrained systems,
  or see ${docdir}/examples/ to open it up to non-root users on the
  system bus or restrict access on the session bus.
  (fd.o #80759; Simon McVittie, Alban Crequy)

• The CMake build system now builds the same shared library name as
  Autotools on at least Linux and Windows:
  - on Linux (and perhaps other Unix platforms), it previously built
    libdbus-1.so, but now builds libdbus-1.so.3.* with development
    symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
  - on Windows, it previously built either libdbus-1.dll (release) or
    libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
    libdbus-1.dll for compatibility with older applications.
  (fd.o #74117, Ralf Habacker)

Enhancements:

• D-Bus Specification version 0.24
  · document how to quote match rules (fd.o #24307, Simon McVittie)
  · explicitly say that most message types never expect a reply
    regardless of whether they have NO_REPLY_EXPECTED
    (fd.o #75749, Simon McVittie)

• on Unix platforms, disable Nagle's algorithm on TCP connections to
  improve initial latency (fd.o #75544, Matt Hoosier)

• use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
  (fd.o #69702, Patrick Welche)

• in dbus-monitor, print more information about file descriptors
  (fd.o #80603, Alban Crequy)

• do not install system bus configuration if built for Windows
  (fd.o #83583; Ralf Habacker, Simon McVittie)

• Add GetAllMatchRules to the Stats interface
  (fd.o #24307, Alban Crequy)

• Add a regression test for file descriptor passing (fd.o #83622,
  Simon McVittie)

Fixes:

• fix an incorrect error message if a Unix socket path is too long
  (fd.o #73887, Antoine Jacoutot)

• in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
  fixing documentation generation (fd.o #75860, Руслан Ижбулатов)

• in Unix with X11, avoid giving dbus-launch a misleading argv[0]
  in ps(1) (fd.o #69716, Chengwei Yang)

• avoid calling poll() with timeout < -1, which is considered invalid
  on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)

• be portable to BSD-derived platforms where O_CLOEXEC is unavailable
  in libc (like Mac OS X 10.6), or available in libc but unsupported by
  the kernel (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)

• Fix include path for test/internal/*.c with cmake (Ralf Habacker)

• Documentation improvements
  (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)

• in dbus-monitor, do not leak file descriptors that we have monitored
  (fd.o #80603, Alban Crequy)

• Set the close-on-exec flag for the inotify file descriptor, even
  if built with CMake or older libc (fd.o #73689, Simon McVittie)

• Remove some LGPL code from the Windows dbus-daemon
  (fd.o #57272, Ralf Habacker)
