We are pleased to announce the GNU Shepherd version 0.10.3, a bug-fix
release of the new 0.10.x series, representing 51 commits over 6 months.

The 0.10.x series is a major overhaul towards 1.0, addressing shortcomings
and providing new features that help comprehend system state.


• About

  The GNU Shepherd is a service manager written in Guile that looks
  after the herd of daemons running on the system.  It can be used as an
  “init” system (PID 1) and also by unprivileged users to manage
  per-user daemons—e.g., tor, privoxy, mcron.  It supports several
  daemon startup mechanisms, including inetd and systemd-style socket
  activation.  The GNU Shepherd is configured in Guile Scheme and can be
  extended in the same language.  It builds on a simple memory-safe and
  callback-free programming model.

  The GNU Shepherd is developed jointly with the GNU Guix project; it is
  used as the init system of Guix, GNU’s advanced GNU/Linux distribution.

• Download

  Here are the compressed sources and a GPG detached signature:
    https://ftp.gnu.org/gnu/shepherd/shepherd-0.10.3.tar.gz
    https://ftp.gnu.org/gnu/shepherd/shepherd-0.10.3.tar.gz.sig

  Use a mirror for higher download bandwidth:
    https://ftpmirror.gnu.org/shepherd/shepherd-0.10.3.tar.gz
    https://ftpmirror.gnu.org/shepherd/shepherd-0.10.3.tar.gz.sig

  Here are the SHA1 and SHA256 checksums:

  aac0f3f11245fca5b13119dc8e25d366fc53df23  shepherd-0.10.3.tar.gz
  jsb+vrAwu1LoTGI/ECnKccLCElFRVhxZFF2qbjuFr+8  shepherd-0.10.3.tar.gz

  The SHA256 checksum is base64 encoded, instead of the
  hexadecimal encoding that most checksum tools default to.

  Use a .sig file to verify that the corresponding file (without the
  .sig suffix) is intact.  First, be sure to download both the .sig file
  and the corresponding tarball.  Then, run a command like this:

    gpg --verify shepherd-0.10.3.tar.gz.sig

  The signature should match the fingerprint of the following key:

    pub   rsa4096 2014-08-11 [SC]
          3CE4 6455 8A84 FDC6 9DB4  0CFB 090B 1199 3D9A EBB5
    uid           [ unknown] Ludovic Courtès <ludo@gnu.org>
    uid           [ unknown] Ludovic Courtès <ludo@chbouib.org>
    uid           [ unknown] Ludovic Courtès (Inria) <ludovic.courtes@inria.fr>

  If that command fails because you don't have the required public key,
  or that public key has expired, try the following commands to retrieve
  or refresh it, and then rerun the 'gpg --verify' command.

    gpg --recv-keys 3CE464558A84FDC69DB40CFB090B11993D9AEBB5

  As a last resort to find the key, you can try the official GNU
  keyring:

    wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
    gpg --keyring gnu-keyring.gpg --verify shepherd-0.10.3.tar.gz.sig


  This release was bootstrapped with the following tools:
    Autoconf 2.71
    Automake 1.16.5
    Makeinfo 7.0.3
    Help2man 1.49.2


• Changes since version 0.10.2 (excerpt from the NEWS file)

  ** Fix a bug that could lead shepherd to hang after loading replacements
     (<https://issues.guix.gnu.org/67839>)

  After loading replacements with ‘herd load’ or ‘guix system reconfigure’,
  shepherd could eventually hang.  Specifically, the replaced service would no
  longer respond to messages, so it would be impossible to start it, to stop it,
  or to unload it.  This is now fixed.

  ** Fix ownership and permissions on Unix-domain sockets
     (<https://issues.guix.gnu.org/67867>)

  When using an AF_UNIX endpoint with systemd- and inetd-style services, the
  socket file itself would remain owned by root (when shepherd is running as
  root) with permissions 755.  This is now fixed, with ownership set according
  to #:socket-owner and #:socket-group of the endpoint, and permissions on the
  socket set to 666.

  Likewise, #:socket-directory-permissions was previously ignored when the
  socket’s directory already existed prior to creating the endpoint, potentially
  leading to unexpectedly wide access to the socket.  This is now fixed.

  ** New #:respawn-delay parameter to ‘service’
     (<https://issues.guix.gnu.org/64665>)

  This specifies a delay before a service is respawned.  Its default value is
  given by ‘default-respawn-delay’ and defaults to 100ms.  Until now, services
  were respawned immediately.

  ** Non-blocking ‘sleep’ replacement provided

  Until now, user code could call (@ (guile) sleep), the core Guile binding for
  ‘sleep’, instead of ‘sleep’ as provided by (fibers).  The former would have
  caused ‘shepherd’ to actually sleep for that time, instead of performing other
  on-going tasks.  ‘sleep’ is now replaced by (@ (fibers) sleep) to avoid that.

  ** Ensure termination of services that failed to produce a PID file

  When a service started with the #:pid-file argument of
  ‘make-forkexec-constructor’ or similar would fail to produce its PID file, the
  process that was spawned would be sent SIGTERM.  Now, it is additionally sent
  SIGKILL after ‘default-process-termination-grace-period’ has expired, as is
  the case when using ‘make-kill-destructor’.

  ** Do not accidentally wait for Linux kernel thread completion
     (<https://issues.guix.gnu.org/67132>)

  In cases a PID file contained a bogus PID or one that’s only valid in a
  separate PID namespace, shepherd could end up waiting for the termination of
  what’s actually a Linux kernel thread, such as PID 2 (“kthreadd”).  This
  situation is now recognized and avoided.

  ** Fix portability issues to GNU/Hurd

  Previous versions in the 0.10.x and 0.9.x series did not work on GNU/Hurd.
  This is now fixed, although some features are still implemented in a
  suboptimal way.

  ** Fix cross-compilation to non-Linux operating systems

  Since 0.10.2, when cross-compiling to systems such as GNU/Hurd, the value of
  ‘SFD_CLOEXEC’ and ‘SFD_NONBLOCK’ in (shepherd system) would be left undefined,
  leading to a type error when starting shepherd.  This is now fixed.

  ** Updated translations: de, ro, sr, sv, uk

  This release is fully translated to German, Romanian, Swedish, and Ukrainian;
  partial translations are available for a dozen of languages.  To help make the
  Shepherd speak your language, check out the Translation Project:
