mod_log_ringbuffer: Detach event handlers on logging reload (thanks Menel)
Otherwise the global event handlers accumulate, one added each time
logging is reoladed, and each invocation of the signal or event triggers
one dump of each created ringbuffer.
local st = require "util.stanza";
module:depends("csi");
module:add_feature("google:queue");
module:hook("iq-set/self/google:queue:query", function(event)
local origin, stanza = event.origin, event.stanza;
(origin.log or module._log)("debug", "Google queue invoked (CSI compat mode)")
local payload = stanza:get_child("query", "google:queue");
if payload:get_child("enable") then
module:fire_event("csi-client-inactive", event);
elseif payload:get_child("disable") then
module:fire_event("csi-client-active", event);
end
-- <flush/> is implemented as a noop, any IQ stanza would flush the queue anyways.
origin.send(st.reply(stanza));
return true;
end, 10);
