component: Avoid adding to the global stream metatable
This allows component and client connections to be made side-by-side.
Previous to this change, loading this connection module would break the
ability to make client connections, due to overriding stream methods such as
:reopen() and :reset().
A next step would be to share the methods that the two connection modules have
in common.
local verse = require "verse"; local gettime = require"socket".gettime; local new_id = require "util.id".short; local xmlns_ping = "urn:xmpp:ping"; function verse.plugins.ping(stream) function stream:ping(jid, callback) local t = gettime(); local id = new_id(); local ping = verse.iq{ id = id, to = jid, type = "get" }:tag("ping", { xmlns = xmlns_ping }); stream:send_iq(ping, function (reply) if reply.attr.type == "error" then local type, condition, text = reply:get_error(); if condition ~= "service-unavailable" and condition ~= "feature-not-implemented" then callback(nil, jid, { type = type, condition = condition, text = text }); return; end end callback(gettime()-t, jid); end); return id; end stream:hook("iq/"..xmlns_ping, function(stanza) return stream:send(verse.reply(stanza)); end); return true; end
