Only useful when debugging. Add a prefix and a stack size indication.
Add optional `thread_init` function support. This function is called per script, per thread to allow a user to initialize the lua state.
dataset.new
create a dataset object in lua
<dataset>:get
gets a reference to an existing dataset
<dataset>:add
returns 1 if a new entry was added
returns 0 if entry was already in the set
Example:
```
function init (args)
local needs = {}
needs["packet"] = tostring(true)
return needs
end
function thread_init (args)
conn_new, dataset.new()
ret, err conn_new:get("conn-seen")
if err ~= nil then
SCLogWarning("dataset warning: " .. err)
return 0
end
end
function match (args)
ipver, srcip, dstip, proto, sp, dp = SCFlowTuple()
str = ipver .. ":<" .. srcip .. ">:<" .. dstip .. ">:" .. dp
ret, err = conn_new:add(str, #str);
if ret == 1 then
SCLogInfo(str .. " => " .. ret)
end
return ret
end
```
