mod_ping_muc: Delay ping a configurable amount of time If a server is restarting, checking immediately before it has a chance to complete its restart and get ready would often fail, preventing the possibility of transparent restarts as supported by Prosody's mod_muc. Reconnecting immediately when a connection is closed for being idle, or because the remote server is trying to reclaim some resources, is also counter-productive as the connection may fail. Also, if there is some Internet routing problem affecting s2s, it may help to wait a bit before checking, in case the problem resolved itself in the mean time.

local hostname = module:get_option_string("sasl_hostname", module.host);

module:hook("stream-features", function(event)
	local features = event.features;
	local mechs = features:get_child("mechanisms", "urn:ietf:params:xml:ns:xmpp-sasl");
	if mechs then
		mechs:tag("hostname", { xmlns = "urn:xmpp:domain-based-name:1" })
			:text(hostname):up();
	end
end);
