mod_websocket: Merge session close handling changes from mod_c2s (bug fixes) This should bring some fixes and general robustness that mod_websocket had missed out on. The duplicated code here is not at all ideal. To prevent this happening again, we should figure out how to have the common logic in a single place, while still being able to do the websocket-specific parts that we need. The main known bug that this fixes is that it's possible for a session to get into a non-destroyable state. For example, if we try to session:close() a hibernating session, then session.conn is nil and the function will simply return without doing anything. In the mod_c2s code we already handle this, and just destroy the session. But if a hibernating websocket session is never resumed or becomes non-resumable, it will become immortal! By merging the fix from mod_c2s, the session should now be correctly destroyed.

-- Compatibility layer for bitwise operations

-- First try the bit32 lib
-- Lua 5.3 has it with compat enabled
-- Lua 5.2 has it by default
if rawget(_G, "bit32") then
	return _G.bit32;
end

do
	-- Lua 5.3 and 5.4 would be able to use native infix operators
	local ok, bitop = pcall(require, "prosody.util.bit53")
	if ok then
		return bitop;
	end
end

error "No bit module found. See https://prosody.im/doc/depends#bitop";
