Problem when sending byte array

Postby Alex » 10 Aug 2010, 12:21

Hi

I'm having trouble sending byte arrays from the server to the client. Sometimes the client throws an exception:

Code: Select all

Error: DumpFormatter: the indentPos is not == 0. TOKENS ARE NOT BALANCED!

Here is a sample byte array that always throws the exception:

Code: Select all

ISFSObject testObject = new SFSObject();

byte[] tb = new byte[] { 73, -56, 0, -97, -87, -67, -68, -124, 30, -41, 84, 21, -39,
      114, -107, -99, -85, 53, -100, -56, 17, -56, -16, 112, 67, -12, 75, 119, -41,
      119, -52, 48, -19, 29, 2, -75, -12, -55, 70, -14, -37, -82, 77, 93, -122, 47,
      -81, -114, -84, -32, 79, -50, -126, 92, -83, -6, -101, 0, -66, -125, -127, -96,

      100, 111, -72, 53, -97, 30, 32, -23, 123, -25, 87, -71, -105, -5, 87, 70, 121, 100,
      113, 50, -107, -43, 32, -121, 95, -12, -52, -13, -26, 51, -43, -24, -128, -25,
      77, 53, -78, 28, 3, -118, 61, -73, 112, -28, 35, 117, -89, 17, -107, -77, -122,
      -88, -92, -93, 59, 48, -35, 4, 21, -128, -107, 87, 64, -97, 110, -111, -30, 46,
      -6, -71, -127, -13, 78, -42, 12, 30, -69, 53, -120, 65, -43, 71, -32, -118, 52,
      35, -108, -21, -88, -15, 87, -55, 31, -18, -15, 94, 110, 93, 60, -104, 1, -83,
       17, -97, 93, 6, 70, 101, 110, -45, 50, 119, 78, 33, 8, -39, 109, -128, 52, 94,
      -38, 17, 111, -31, -64, -108, -80, 57, -47, 121, 28, -35, -94, -104, 10, -13 };

testObject.putByteArray( "m", tb );

ce.getApi().sendExtensionResponse( CommonCommandNames.SYSTEM_MOVE_SEND, testObject, user, room, false  );

Thanks I will investigate.
Small suggestion... instead of callin:

Code: Select all

getApi().sendExtensionResponse(....

you have convenient send(...) method inside your extension or event/request handler.

Essentially it's the same thing but nicer :)

Yep there is indeed a bug with the object dump of byte arrays. Quite a stupid one :(
You can download the latest API which provides a fix.
API version 0.9.0

Hello,

I'm trying to send a byte array from my Java server extension, but there are some problems on the client iPhone side exactly like described above.
Could you please help?
I think this problem was fixed only for the AS3 and Unity clients (in RC1a update) but not for iPhone.

I don't know if the problem is exactly the same, maybe.
So you are getting the same error message of the Actionscript version?

The code on Java:

Code: Select all

   public void createGameWithMap(User user, int w, int h, String map)
   {
      SFSObject response = new SFSObject();
      response.putInt("w", w);
      response.putInt("h", h);
      response.putLong("t", System.currentTimeMillis());
      response.putByteArray("m", map.getBytes());

      send("createGameWithMap", response, user);
   }

Upon closer inspection it looks like the problem is not related with the issue originally posted. Does it happen with specific byte arrays or just any byte array?

Thank you

Ok, I think the problem is in the packet size which exceeds "Protocol compression threshold" (1024 bytes by default).
I can see these lines in the iPhone client:

Code: Select all

-(NSData *)handlePacketData:(NSData *)data {

...
      
if (_pendingPacket.header.compressed) {
   // TODO  handle compression...
}

...

}


When I'm sending bytes array with length > 1024 bytes it's crashes with callstack I posted above.

I am still having the issue after downloading and using the update.

For example if I send a string, or multiple strings, that are too long I get the crash on the ios side.

Here is the server side code sending an example string that is 1514 chars long.

Code: Select all

package myZone;

import java.util.LinkedList;

import com.smartfoxserver.v2.entities.User;
import com.smartfoxserver.v2.entities.data.ISFSObject;
import com.smartfoxserver.v2.entities.data.SFSObject;

public class JoinGameReqHandler extends BaseClientRequestHandler
{

   @Override
   public void handleClientRequest(User sender, ISFSObject params)
   {
      LinkedList<User> receiverList = new LinkedList<User>();
      receiverList.add(sender);

      ISFSObject response = new SFSObject();
      
      response.putUtfString("test", "This is a free typing test that tests your typing speed. Typing speed is defined in wpm, which is words typed per minute. A word is taken to be five characters long including blank spaces. Typing speed is also defined as strokes typed per minute. This typing speed test will tell you your typing speed in wpm, words per minute, as soon as you finish typing this short paragraph. This is a free typing test that tests your typing speed.

      send("joinGame", response, receiverList);
   }
}


This is the crash on the ios side when trying to receive the packet containing the test string.
