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 bytes = module:measure("bytes", "sizes");
local lines = module:measure("lines", "distribution");
local words = module:measure("words", "distribution");
local function measure_length(event)
local body = event.stanza:get_child_text("body");
if body then
bytes(#body);
lines(select(2, body:gsub("[^\n]+","")));
words(select(2, body:gsub("%S+","")));
end
end
