Hi, Felix Lechner via "Development of GNU Guix and the GNU System distribution." <guix-devel@gnu.org> skribis:
> Are 'herd status' and 'herd status NAME' supposed to block on > long-running timers like this one? [1] Thanks! In this case the timer is using a Scheme procedure, not a <command> record. Procedures must be written in a non-blocking/suspendable fashion, as noted in the manual. That said, I don’t immediately see what could block in your timer: it uses ‘system*’ to spawn processes, which is suspendable inside shepherd. Would be nice if you explain when it’s blocking and/or use ‘strace’ to see what’s going on while it’s blocking. That said, this timer is a bit long; I’d suggest going for something simpler and/or deferring to a <command> that does the heavy lifting. HTH, Ludo’.
