Problem with Type 13 (SZARRAY)

Spoko · October 8, 2012, 3:31pm

Hello every one !
first of all sorry if i made mistake i’m french ^^

So i use code exemple in the ebook " internet of thing", that great but i try to modify a little.

Now i have a problem in the GC => Type 13 (SZARRAY) take more and more space and so the card do not answer …

here is the code :

using System;
using System.Threading;
using System.Text;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using GHIElectronics.NETMF.FEZ;
using GHIElectronics.NETMF.Hardware;
using GHIElectronics.NETMF.Net;
using GHIElectronics.NETMF.Net.NetworkInformation;
public class Program
{
    public static void Main()
    {



        OutputPort red = new OutputPort((Cpu.Pin)FEZ_Pin.Digital.Di2, false);
        OutputPort green = new OutputPort((Cpu.Pin)FEZ_Pin.Digital.Di3, false);
        OutputPort yellow = new OutputPort((Cpu.Pin)FEZ_Pin.Digital.Di1, false);

        green.Write(false);
        string ValeurLedVerte = "allumer";
        string LectureLedVerte = "eteint";

        yellow.Write(false);
        string ValeurLedOrange = "allumer";
        string LectureLedOrange = "eteint";

        red.Write(false);
        string ValeurLedRouge = "allumer";
        string LectureLedRouge = "eteint";




        PWM piezo = new PWM((PWM.Pin)FEZ_Pin.PWM.Di5);
        byte[] ip = { 192, 168, 0, 200 };
        byte[] subnet = { 255, 255, 255, 0 };
        byte[] gateway = { 192, 168, 1, 1 };
        byte[] mac = { 0x00, 0x88, 0x98, 0x90, 0xD4, 0xE0 };
        WIZnet_W5100.Enable(SPI.SPI_module.SPI1, (Cpu.Pin)FEZ_Pin.Digital.Di10, (Cpu.Pin)FEZ_Pin.Digital.Di7, true);
        NetworkInterface.EnableStaticIP(ip, subnet, gateway, mac);
        NetworkInterface.EnableStaticDns(gateway);
        // start server
        HttpListener listener = new HttpListener("http", 80);

        
         




        listener.Start();

                response = context.Response;
                request = context.Request;

OOMs are not uncommon when using networking and USBizi based boards. The issue you’re hitting is most likely needing to allocate contiguous space but being unable to find this.

You can force the GC to clean up and hopefully readjust available space for you. Use a code block like this:

			Debug.GC(true);
			Debug.Print("Free mem : " + Debug.GC(false).ToString());

The Debug.GC(True) forces GC to run, and then the (false) shows the available free memory. See if that assists; I’d add it in your HTTP loop.

Valkyrie_MT · October 8, 2012, 4:27pm

What firmware version are you running? 4.1?

Brett · October 8, 2012, 4:31pm

yes - its a usbizi Wiz5100 which doesn’t have 4.2 support

Spoko · October 8, 2012, 5:18pm

@ Brett it still the same …
the mem decrease each time i press a button …

thank for help !

Brett · October 8, 2012, 6:17pm

where did you add it?

Spoko · October 9, 2012, 4:33am

I had it in the

while(true)

and in the

if( request == "POST")

I try to had it every where but it dosen’t work …

Spoko · October 10, 2012, 4:44am

nobody have idea ?

i’m very lost …

thanks.

Brett · October 10, 2012, 7:13am

So the problem is in your code, unfortunately. It’s probably too big for most people to delve into and see where you’re leaking objects and where you could clean up and avoid this.

Jasdev has a really stable footprint web server at http://www.tinyclr.com/codeshare/entry/363 so I would suggest you take a look at his code. It’s pretty simple to expand for your case - and if nothing else you can look at how his code works in the same area and you can maybe get some tips to optimise your code.

jasdev · October 10, 2012, 7:41pm

Sorry for the above post… I clicked the quick post button by accident !

Thanks Brett

@ Spoko - In your while loop you are doing a lot of buffer allocation and re-allocation:


    byte[] buffer = new byte[(int)request.ContentLength64];
     request.InputStream.Read(buffer, 0, (int)request.ContentLength64);
     string actionAeffectuer = new string(Encoding.UTF8.GetChars(buffer));
 
    // la variable actionAeffectuer contient "name"="value"
     int index = actionAeffectuer.IndexOf('='); // on obtient la place de "="
    actionAeffectuer = actionAeffectuer.Substring(0, index);

I would suggest that you allocate a fixed byte buffer before you enter the while loop that is larger than the largest content length you are expecting, and then call the Read method like this:


     bytesRead = request.InputStream.Read(buffer, 0, buffer.Length);

Then
[ol]use bytesRead to do a sequential search (using a for loop) for your ‘=’ character to determine the index.
convert only the bytes up to the index position to a string[/ol]

dizzy · October 10, 2012, 10:23pm

i think jasdev probably has the right fix (or one of them).

also, i’m not sure about how .netmf compiler will treat this code:

        while (true)
        {
            HttpListenerResponse response = null;
            HttpListenerContext context = null;
            HttpListenerRequest request = null;
            ....
            ....
         }

to be safe, i’d probably move that outside the loop as well, just in case new instances are being allocated each loop…

EDIT: just looked at the documentation for system.net.HttpListenerContext and I see that it implements Finalize. This means that this object is going to survive the first garbage collection at the very least and live on to gen1. so i think if that loop is assigning new instances, and given that finalization is indeterminate…then it is likely you have memory claimed by those objects living on longer than you want.

Spoko · October 11, 2012, 5:19am

@ jasdev

i don’t understand what you mean …

but bytesRead is an “int” …

@ dizzy
i try what you say but it’s still the same …

@ Brett

this project was too big for me but i will try it.

thnaks a lot for every body !!

Brett · October 11, 2012, 6:00am

I think @ Jasdev is saying do a loop from 0 to readBytes, check if the character is “=”

but i have style the same problem
after something like 20 hit on the web page of the button i have an outofmemory …

I don’t know what i can do more …

thanks for reading.

i’m going to burn my FEZ PANDA ^^
please help me …

mhectorgato · October 15, 2012, 10:48am

Sorry … I’ve not read through the whole thread, just the error your getting about (out of memory).

(I don’t have a board in front of me, so these are just off the top of the head observations)

Have you tried forcing the Garbage Collection after you set your references to null?
Do you you call Dispose() on the disposable objects?
Since you are always returning the same static data in your response, how about making that a const? (unless that’s just for testing)

but the out of memories come faster …

I don’t know what is Dispose() ?

[EDIT]
i found Dispose(), i try it and come back to say if it work
THANKS !!!
[\EDIT]

Mike · October 15, 2012, 11:00am

I suggest that you wrap the Panda in an old newspaper, douse with a flammable liquid, and then ignite.

Please mark your question as answered.

Spoko · October 15, 2012, 11:20am

I can’t use Dispose(), it say to me that maybe it miss an using or an assembly.

I try it on :

HTML

context

request

response

whitout succes

but on green ( the object for the port) it’s work …

mhectorgato · October 15, 2012, 11:44am

Saw the [EDIT] - does this mean that your problem is resolved?
