dbus-1.16.0 (Wait for lfs)

[Bruce Dubbs]

New minor version.

[Xi Ruoyao]

Build system and dependencies:

• The Meson build system is the recommended way to build dbus on Unix. This requires Meson 0.56 and Python 3.5.
  • Projects that depend on libdbus can build it as a Meson subproject. See tests/use-as-subproject/meson.build for suggested build options.

• CMake continues to be available as an alternative build system, and is recommended on Windows. This requires CMake 3.10.

• A C99 compiler such as gcc, clang, or Visual Studio 2015 is required. A C11 compiler such as gcc, clang, or Visual Studio 2019 is recommended.

• On platforms with larger-than-64-bit pointers, a C11 compiler is required

Behaviour changes:

• On Unix, the well-known system bus socket is in the runtime state directory by default (normally /run) (see 1.15.4 for more details)

• On Linux with systemd, dbus-daemon starts as the target user/group (retaining CAP_AUDIT_WRITE) instead of starting as root and dropping privileges

Feature removals:

• Autotools build system

• pam_console/pam_foreground integration (Autotools --with-console-auth, CMake -DDBUS_CONSOLE_AUTH_DIR)

New features and significant bug fixes:

• ProcessFD in GetConnectionCredentials() on Linux (see 1.15.8 for more details)

• On Unix, the system message bus now loads .service files from /etc and /run

• Use close_range() to close unwanted file descriptors or mark them close-on-exec, if available

• Use 64-bit timestamps internally on 32-bit platforms, for Y2038 safety

• Use APIs that can return 64-bit timestamps and inode numbers on 32-bit glibc

• AF_UNIX sockets are available on sufficiently recent Windows

• dbus-send can send arrays of variants, variant values in dictionaries, and nested variants

• Portability to CPU architectures with larger-than-64-bit pointers

mkdir build

# Most options we explicitly gave to "./configure" are not needed now
meson setup --prefix=/usr --buildtype=release ..

ninja
ninja test
sudo ninja install
sudo mv -v /usr/share/doc/dbus{,-1.16.0}

# if running unit tests, reconfigure the build after installation:
meson configure -D asserts=true -D intrusive_tests=true
ninja test

Oh, we also need --wrap-mode=nofallback or it'll download a Glib copy for some tests, if Glib is not installed.
