LUA scripts hangs

[madrian]

I have a Dimmer switch and I want to set level when It's turned on (by default it's only switching on, without level change):

Code: Select all

 if devicechanged[DomDevice] then
   
      lastValue = os.execute ("php /home//domoticz/userscripts/bedled.php")
      print(lastValue)

   print("dev " .. devicechanged[DomDevice]);

   if(devicechanged[DomDevice]=='On') then
      commandArray[DomDevice] = 'Set Level 40' --test
      return commandArray
   end
end

(bedled.php output is a json processor, which outputs the last value of the dimmer, example 43)

Result?

Code: Select all

Domoticz freezes.

I even tried to decode JSON directly in LUA, same problem:

Code: Select all

local address = '192.168.1.54:8080'
url   = 'curl "http://'..address..'/json.htm?type=devices&rid=25"'
local config=assert(io.popen(url)
local location = config:read('*all')
config:close()
local jsonLocation = json:decode(result)

Similar reports have been made about os.execute() not properly ending and returning but hanging for 10 seconds.
Just add an & at the end of the commandline to have it return right away, but of course you miss the return code.

Code: Select all

lastValue = os.execute ("php /home//domoticz/userscripts/bedled.php &")
