masakk1 / setpeername_doesnt_care.lua

Created February 25, 2025 22:53

`:setpeername()` doesn't care whether its connected or not. Contrary to `luasocket`'s documenation.

	local socket = require("socket")

	-- Proof that `:setpeername()` doesn't care whether it's connected or not
	-- On the other hand, `:getpeername()` errors if the UDP object isn't connected
	local udp, err = socket.udp()
	assert(udp, err)

	local function print_peer(message)
	print(message)
	local success, result = pcall(udp.getpeername, udp)

	local client, err = socket.udp()
	local server, err = socket.udp()

	server:setsockname("127.0.0.1", 12345)
