net.server_epoll: Add support for systemd socket activation
Allows creating listening sockets and accepting client connections
before Prosody starts.
This is unlike normal Prosody dynamic resource management, where ports
may added and removed at any time, and the ports defined by the config.
Weird things happen if these are closed (e.g. due to reload) so here we
prevent closing and ensure sockets are reused when opened again.
module:set_global();
local filters = require "prosody.util.filters";
local function log_send(t, session)
if t and t ~= "" and t ~= " " then
session.log("debug", "SEND: %s", t);
end
return t;
end
local function log_recv(t, session)
if t and t ~= "" and t ~= " " then
session.log("debug", "RECV: %s", t);
end
return t;
end
local function init_raw_logging(session)
filters.add_filter(session, "stanzas/in", log_recv, -10000);
filters.add_filter(session, "stanzas/out", log_send, 10000);
end
filters.add_filter_hook(init_raw_logging);
