What leak in following lines ?

[sujithkrishnan]

Hi,

I am attaching the screenshot of the INSTRUMENTS mem-leak stach trace.
When i go to the line mentioned in INSTRUMENTS, i found leak is in the following lines....


INSTRUMENTS Showing REALLOC in this line... ( I am calling this line many times in file, but i am not using any explicit alloc for any of variable)
This line is in a method and method returns me the NSData it recieved from URL, when i pass the URL to it...

-(NSData *)httpConnectionHandler:(NSString *)URL  xmlString:(NSMutableString *)xmlDataInStringForm
{
	
	
	NSString *URLString = [NSString stringWithFormat:@"http://stage.digby.com/30ss/%@?%@",URL,xmlDataInStringForm];
	
	URLString = [URLString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];	
	
	NSMutableURLRequest *orderRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:URLString]];
	[orderRequest addValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
	[orderRequest setHTTPMethod:@"GET"];
	
	NSURLResponse *orderResponse=nil;
	NSError *orderResponseError=nil;
	
	NSData *recievedOrderData = [NSURLConnection sendSynchronousRequest:orderRequest returningResponse:&orderResponse error:&orderResponseError];
		
	return recievedOrderData;
	

}

Another leak is showing in this line

// praserObject is a property...
parserObject = [[NSXMLParser alloc] initWithData:receivedData1];

(I think in following line, the previous string is losing its reference, when we oveerwrite with new string...)

URLString = [URLString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];	

But what wrong woth following?????????
Instruments showing

BOOL success = [NSKeyedArchiver archiveRootObject:[CustomerInfo getCustomerObject] toFile:writableDBPath];

if([[itemObject.iImg substringToIndex:4] isEqualToString:@"http"])
	 {
		 //NSAutoreleasePool *poolObj = [[NSAutoreleasePool alloc]init];
		 
		 NSURL *urlString = [[NSURL alloc]initWithString:itemObject.imgName];
		 NSData *data  = [[NSData alloc]initWithContentsOfURL:urlString];
		 UIImage *img = [[UIImage alloc]initWithData:data];
		 cell.image = img; 
		 [img release];
		 [data release];
		 [urlString release];     //[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:itemObject.iImg]]];
		
		 //[poolObj drain];
	}
	else
	{ 
		 cell.image = [UIImage imageNamed:itemObject.iImg];
	}
	     state = 1;
	}			 
	
	return cell;

Hi all,

May I know what is the server you are using , Remote server or local server.
I found a strange behaviours for the http connection using NSURL.

a) When I am using the remote server,
I am not getting any memory leak.
b) When I am using the local server
i) with IP Address in the url, I am didnt got any memory leak.
ii) with Domain name(eg: http://somelocalserver/test1.xml) I am getting the memory leaks.

So If u find any issue related to this or any solution for the part b. or reasons for this behaviour please reply.

Thank u.
