730706 - kumascript: Build forking, robust server runner

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: Editing, defect)

Description

[Les Orchard [:lorchard]]

The HTTP service for kumascript is a JS module that can be run as a socket listener. That's not enough, though: It needs to be wrapped in a deployable server runner that will keep the service running through exceptions and errors, and can fork processes to take advantage of multiple CPU cores.

This may need some IT consultation to determine what's the best arrangement for deployment.

Preempting some IT questions - the http service is served by node.js? Is it express? Are there existing node.js practices and tools for this?

The HTTP service is node, based on express, and there are many existing node practices and tools. Still working on picking the right one, though "up" [1] looks promising. 

There's also "forever" [2], but that doesn't handle forking off child processes. I'd probably need to DIY that with the new "cluster" support in node [3].
