The latest news are:
1. Support for inetd-style services¹, where shepherd listens and
accepts client connections, starts the daemon and hands it the
connection socket—e.g., ‘sshd -i’.
Each daemon process is handled as a “transient service”, a new type
of service that is automatically unregistered when it’s done. You
can see those when running ‘herd status’; in the OpenSSH example,
you’d see ‘sshd-1’, ‘sshd-2’, etc. corresponding to individual SSH
client connections.
2. Support for systemd-style “socket activation”², where shepherd
listens, spawns the daemon when the first request arrives, and
hands it the *listening* socket.
From the user viewpoint, this one is similar to the existing
‘make-forkexec-constructor’ type of service. The main difference
is that its “running value” as shown by ‘herd status SERVICE’ is
initially a socket and then becomes a PID.
My plan is to merge ‘wip-fibers’ in ‘master’, publish a release
candidate, publish a ‘wip-’ branch of Guix that we can use for testing,
and hopefully release the Shepherd 0.9.0 within a week or two.
