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";
local omemo_namespace_prefix = "eu.siacs.conversations.axolotl."
module:hook("iq/bare/http://jabber.org/protocol/pubsub:pubsub", function (event)
local origin, stanza = event.origin, event.stanza;
local node = stanza.tags[1].tags[1].attr.node;
if node and node:sub(1, #omemo_namespace_prefix) == omemo_namespace_prefix then
origin.send(st.error_reply(stanza, "cancel", "item-not-found", "OMEMO is disabled"));
return true;
end
end, 10);
