=E2=80=A2 About

  The 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
  =E2=80=9Cinit=E2=80=9D system (PID 1) and also by unprivileged users to m=
anage
  per-user daemons=E2=80=94e.g., gpg-agent, tor, privoxy.  It supports seve=
ral
  daemon startup mechanisms, including inetd, systemd-style socket
  activation, and timers.  The 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 Shepherd is developed jointly with the Guix project; it is used as
  the init system of Guix System and service manager of Guix Home.

=80=99 tag of
  the Git repository.


=E2=80=A2 Changes since version 1.0.2

  ** =E2=80=98spawn-command=E2=80=99 now honors #:log-file

  The =E2=80=98spawn-command=E2=80=99 procedure now accepts a #:log-file ar=
gument, just like
  =E2=80=98fork+exec-command=E2=80=99.

  ** New =E2=80=98--syslog=E2=80=99 option of =E2=80=98shepherd=E2=80=99

  This option forces shepherd to write its output to syslog (the /dev/log s=
ocket
  by default).  This is already the case when shepherd runs as root so this
  option only makes sense for non-root shepherd instances, and its primary
  purpose is testing.

  ** Always decode client commands as UTF-8
     (<https://issues.guix.gnu.org/76244>)

  Previously client commands send by =E2=80=98herd=E2=80=99 would be decode=
d according to the
  locale encoding of the =E2=80=98shepherd=E2=80=99 process, which could be=
 ASCII; now they=E2=80=99re
  always decoded as UTF-8, as intended.

  ** Internal logging is always UTF-8
     (<https://issues.guix.gnu.org/76244>)

  The so-called =E2=80=9Cservice output port=E2=80=9D, where internal loggi=
ng from shepherd
  itself goes, is now always UTF-8-encoded (instead of following locale
  encoding).

  ** Log output missing a newline is preserved
     (<https://issues.guix.gnu.org/76243>)

  It used to be that service output missing a final newline would not be lo=
gged,
  for example when running =E2=80=9Cherd spawn transient -- echo -n aaaaa=
=E2=80=9D.  This is now
  fixed.

  ** Default generated configuration file updated to match current interface
     (<https://issues.guix.gnu.org/76403>)

  The ~/.config/shepherd/init.scm generated when it doesn=E2=80=99t already=
 exist would
  use deprecated and removed interfaces.  This is now fixed.

  ** Inhibit service respawn during shutdown
     (<https://issues.guix.gnu.org/76338>)

  Until now, the ability to respawn services remained functional during shu=
tdown
  (with =E2=80=98herd stop root=E2=80=99, =E2=80=98reboot=E2=80=99, etc.). =
 This caused troubles on Guix System
  where the =E2=80=98user-processes=E2=80=99 service terminates all process=
es when it is stopped
  and which, as a consequence, could lead shepherd to respawn services, even
  though it was being shut down.

  ** Tolerate slight delays when waiting for a timer event
     (<https://issues.guix.gnu.org/76516>)

  Previously, timers could occasionally get slightly more than a 2-second d=
elay,
  which would lead them to skip their deadline (with a message saying =E2=
=80=9Cresuming
  from sleep state?=E2=80=9D).  Delay tolerance has been increased.

  ** Silence warning about =E2=80=98environ=E2=80=99 when using Guile 3.0.10
     (<https://issues.guix.gnu.org/76343>)

  When using Guile 3.0.10, commands such as =E2=80=98shepherd --help=E2=80=
=99 would print an
  erroneous warning about =E2=80=98environ=E2=80=99 being called from a mul=
ti-threaded context.
  This is now fixed.

  ** Correctly report the exit status of processes terminated early
     (<https://issues.guix.gnu.org/76790>)

  For services using =E2=80=98fork+exec-command=E2=80=99, there used to be =
a small window after
  creating the process and before monitoring it during which process termin=
ation
  would be mishandled: =E2=80=98herd status SERVICE=E2=80=99 would report t=
hat the process
  exited successfully, whether or not this was the case.  This is now fixed.

  ** Several flaky tests have been made more robust

  Several tests were =E2=80=9Cflaky=E2=80=9D: they would fail randomly, typ=
ically when run on
  loaded or slow machines.  The underlying race conditions were identified =
and
  fixed.
