How could I realize `aos [myProcess] --cron 5-minutes` in sub-process‘ lua code when using ao.spawn

[xgocn]

    local newProcess = ao.spawn(ao.env.Module.Id, {
      Authority = ao.id
    }).receive()

    ao.send({
      Target = newProcess.Process,
      Action = 'Eval',
      Data = [[
            Handlers.add(
                'CronTick', 
                Handlers.utils.hasMatchingTag('Action', 'Cron'), 
                 function(msg)
                    msg.reply({ Data = 'Pong'})
                end
            )
        ]]
    })

Spawn(ao.env.Module.Id, {
  Authority = ao.id,
  ["Cron-Tag-Action"] = "Cron",
  ["Cron-Interval"] = "5-minutes"
 })

You will have to use the MU REST endpoint to engage monitoring...

POST https://mu.ao-testnet.xyz/monitor/:processid

When we define spawn, newprocess has not defined handler yet. Is cron already running? When we add handlers.add in the later part, it has business logic. Before that, is cron executing an empty loop?

[twilson63]

Yes cron calculates implicit messages based on interval, if you don't handle them, they will go into your inbox

I just ran curl -X POST https://mu.ao-testnet.xyz/monitor/b3WAvKqYrdsLBtGkNVPD5RpeJERy1WiCA3LBbf6LmPI

got {"error":"this.binary.subarray is not a function"}

[xgocn]

I believe the newprocess is running，because I send a Ping and got a Pong

[xgocn]

this is my code

    -- parent process : l7ph6gka-mmrVE5P23lRa-1BWgQC8MXH8FcTbs6wk_U 
    Handlers.add(
    'ping',
    Handlers.utils.hasMatchingTag('Action', 'Ping'),
    function(msg)
        print("Received Ping from: " .. msg.From)
        msg.reply({ Data = 'Pong from Main Process：' .. tostring(ao.id)})
    end
   )

    local newProcess = ao.spawn(ao.env.Module.Id, {
        Authority = ao.id,
        ["Cron-Tag-Action"] = "Cron",
        ["Cron-Interval"] = "10-seconds"
    }).receive()

    print(newProcess.Process)
   -- got jSj0KUIDJN8gx8PW5-MLZ_gTAaY6_EQd0N3Kl6AT6YY

    DB:exec(string.format("UPDATE npc SET proc_id = '%s' WHERE id = %d", newProcess.Process,npcId))

    ao.send({
      Target = newProcess.Process,
      Action = 'Eval',
      Data = [[
            Handlers.add(
                'ping',
                Handlers.utils.hasMatchingTag('Action', 'Ping'),
                function(msg)
                    ao.send({Target = 'l7ph6gka-mmrVE5P23lRa-1BWgQC8MXH8FcTbs6wk_U',Action = 'Ping'})
                    msg.reply({ Data = 'Pong'})
                end
            )

            Handlers.add(
                'CronTick', 
                Handlers.utils.hasMatchingTag('Action', 'Cron'), 
                function(msg)
                    ao.send({Target ='l7ph6gka-mmrVE5P23lRa-1BWgQC8MXH8FcTbs6wk_U',Action = 'Ping'})
                    msg.reply({ Data = "NPC has died." })
                end
            )
        ]]
    })

I make test like：

SUS@aos-2.0.0[Inbox:90]> Send({Target="jSj0KUIDJN8gx8PW5-MLZ_gTAaY6_EQd0N3Kl6AT6YY",Action="Ping"})
{
   onReply = function: 0x227dc60,
   output = "Message added to outbox",
   receive = function: 0x227dd00
}
Received Ping from: jSj0KUIDJN8gx8PW5-MLZ_gTAaY6_EQd0N3Kl6AT6YY

but the cron part didn't work，so I make a futher test: I call Cron as a common handler,it responed

SUS@aos-2.0.0[Inbox:91]> Send({Target="jSj0KUIDJN8gx8PW5-MLZ_gTAaY6_EQd0N3Kl6AT6YY",Action="Cron"})
{
   onReply = function: 0x227d9e0,
   output = "Message added to outbox",
   receive = function: 0x227d840
}
Received Ping from: jSj0KUIDJN8gx8PW5-MLZ_gTAaY6_EQd0N3Kl6AT6YY

by far,I consider the handler's code is correct and the cron works too,but can't ao.send a Ping under Cron mode

what could the problem be?

[xgocn]

who is the singer of a cron handler in sub-process,maybe no one?

[twilson63]

singer?

If you mean signer, cron messages are generated implicitly.

Thx

yes, signer,if cron messages are generated implicitly,the

Handlers.add(
                'CronTick', 
                Handlers.utils.hasMatchingTag('Action', 'Cron'), 
                function(msg)
                    -- here
                    ao.send({Target =parentProcess,Action = 'Ping'})
                    -- 
                    msg.reply({ Data = "NPC has died." })
                end
            )

the ao.send didn‘t work under implicit mode in my test, BUT works when called as a standard handler like SUS@aos-2.0.0[Inbox:91]> Send({Target=:NEWPROCESSID,Action="Cron"})

[twilson63]

do you have a test script you can share?

the ao.send didn‘t work in my test

test.zip

the ao.send in Cron doesn't work for unknown reason

[xgocn]

And I‘m not the only one who met the problem

[twilson63]

Sorry, traveling, I will review your code as soon as possible.

Thanks

Have a good time!

[antaintan]

I had the same problem

[windTrace]

yes, bug exists when call ao.send in Cron of spawned sub-process
