Make socket code event-driven #100

Closed HenryHRich closed 2 years ago

HenryHRich commented 2 years ago

The goal is to allow asynchronous sockets, for which an event (new data or newly able to accept data) generates a call to a J socket handler. This will allow a J program to be fully event-driven, waiting for UI, socket, timer, or user events.

Is "asynchronous" separate and distinct from "event-driven"?

How will 'event-driven' be different from the architecture of the existing JHS server?

There's some previous work on async server code here: https://code.jsoftware.com/mediawiki/images/c/c6/Jbillserver.ijs

I want to get back the asynchronous socket support that was in J6.02 for Windows. This is not about JHS Server, but about having the desktop application get event calls rather than having to poll sockets.

There is a need to use event-driven sockets.

jqt already reimplemented sdasync. Isn't this what you had asked for?

Bill says it's fixed.
