I'm so excitoid

It has slightly more features than service-runner even, and we would likely have used it a while ago if there wasn't this catch about it being commercial software that also requires a subscription. I knew about forever, but not forever-service. Thanks for the link! Both are solving a different problem: forever basically tries to be a replacement for daemon managers like start-stop-agent, while forever-service hooks it up with the actual init system. Both could potentially come in handy as part of a distribution solution on less common platforms, especially where there isn't a good init system. On Linux we now have a very modern init system with systemd though, and I think just using it makes a lot of sense. While forever (like an init system or start-stop-daemon) is all about managing a subprocess, system-runner actually becomes part of the node service process. It parallelizes web services by managing workers all listening on the same socket, sets up non-blocking remote logging and automatically collects heap metrics in each worker it spawns. It is complementary to init systems or forever in many ways. For example, forever or init systems typically send a SIGTERM to ask for a graceful restart, while service-runner has a handler for SIGTERM that triggers the actual graceful restart by instructing its workers to stop accepting new requests & exiting after ongoing requests have finished. Thank you! I merged & tweaked it a little in a follow-up. The memory saving comes from only starting one process (which parsoid already supports). Service-runner additionally lets us run multiple services in a single process, which can save memory over having one process per service. You lose isolation and parallelism of course, but that's an okay price to pay if you are set on running all those services in 100mb of RAM. Also, Parsoid does not use service-runner yet. First commit was only last weekend. Ha! And I thought we had just freed ourselves from the *oids ;) Gabriel _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

I haven't looked into feature sets and/or requirements at all, but has anyone looked into PM2 ? https://github.com/Unitech/pm2 I know we use it internally at my company and that folks are reasonably happy with it (compared to the other stuff that is out there).
