History

Andy Green 498a4e2bd7 sul: all timed objects use a single pt sul list wsi timeout, wsi hrtimer, sequencer timeout and vh-protocol timer all now participate on a single sorted us list. The whole idea of polling wakes is thrown out, poll waits ignore the timeout field and always use infinite timeouts. Introduce a public api that can schedule its own callback from the event loop with us resolution (usually ms is all the platform can do). Upgrade timeouts and sequencer timeouts to also be able to use us resolution. Introduce a prepared fakewsi in the pt, so we don't have to allocate one on the heap when we need it. Directly handle vh-protocol timer if LWS_MAX_SMP == 1		2019-08-09 10:12:09 +01:00

lws minimal ws proxy

Build

 $ cmake . && make

Description

This is the same as minimal-ws-server-ring, but with the inclusion of a ws client connection to https://libwebsockets.org using the dumb-increment protocol feeding the ringbuffer.

Each client that connect to this server receives the content that had arrived on the client connection feeding the ringbuffer proxied to their browser window over a ws connection.

Usage

 $ ./lws-minimal-ws-proxy

Visit http://localhost:7681 on multiple browser windows

Data received on the remote wss connection is copied to all open browser windows.

A ringbuffer holds up to 8 lines of text in the server, and the browser shows the last 20 lines of received text.
