Hi Attila, Apologies for the delay, I’m seeing this just now.
Attila Lendvai <att...@lendvai.name> skribis: > posix signal handlers are async, and shepherd uses the fibers API from > inside signal handlers, specifically in at least handle-SIGCHLD. Shepherd has two modes: ‘signalfd’ on Linux, and Guile signal handlers elsewhere (= GNU/Hurd). The latter sucks for many reasons and was plain untested until recently because GNU/Hurd support had been lost (Fibers used to be Linux-only). The behavior on signalfd-less systems is now fixed in 0.10.3, though in suboptimal ways. At a fundamental level, we should fix signal handling in Guile and Fibers to avoid race conditions. (And get ‘signalfd’ on the Hurd. :-)) HTH! Ludo’.
