[Freeswitch-users] A few questions about lua

I have a few questions when scripting lua. According to wiki, it is possible
to run looping forever lua scripts through start-up config or luarun.

1) Will the lua script stop when unload mod_lua? I experienced core dump
when unload mod_lua while there was a running lua script. Reported on jira.

2) How to stop a forever running lua script?  I stop it by listening a
CUSTOM event fired elsewhere. See code below. Is there any standard way like
luastop ?

3) Any way to show how many running lua scripts? luashow ?

4) It seems cannot get the lua script name in a lua script, I made a patch
to jira by assign it to the argv[0].

5) Seems that only EventConsumer("all") working.
EventConsumer("CHANNEL_HANUP CUSTOM lua::stop") doesn't seem to work. Any
idea to this?

Thanks a lot.

code example:

con = freeswitch.EventConsumer("all");

argv[0] = "test.lua"

freeswitch.consoleLog("info", "==== Lua Script [" .. argv[0] .. "] Starting

local all_events = 0

for e in (function() return con:pop(1) end) do
  -- freeswitch.consoleLog("info", "event\n" .. e:serialize("xml"));
   all_events = all_events + 1;
freeswitch.consoleLog("info", "all_events: " .. all_events .. "\n")
 event_name = e:getHeader("Event-Name") or ""
event_subclass = e:getHeader("Event-Subclass") or ""
 if (event_name == "CUSTOM" and event_subclass == "lua::stop") then
  freeswitch.consoleLog("info", "-----lua Script [" .. argv[0] ..
