websocket (or cosocket?) multiple writers concurrency

tavishnaruka

Hi,

Just a quick question, I am using lua-resty-websocket to create a websocket server, which spawns multiple light-threads to which I pass the socket I get from resty.websocket.server:new(), they are all write only, and only the main thread is reading form the socket. Now do I need a lock or semaphore before wb:send_binary() etc.?

Hi, you cannot have too light thread write one socket.Here is official document.

Starting from the 0.9.9 release, the cosocket object here is full-duplex, that is, a reader "light thread" and a writer "light thread" can operate on a single cosocket object simultaneously (both "light threads" must belong to the same Lua handler though, see reasons above). But you cannot have two "light threads" both reading (or writing or connecting) the same cosocket, otherwise you might get an error like "socket busy reading" when calling the methods of the cosocket object.
