memory leaks

[rendner]

I tested my app with instruments from xcode and found some memory leaks. One leak cames from the method "- (id)initWithCanceller:(id)cancellerFunc" of the class "DKDeferred".
The retained "deferedID" (deferredID = [_uuid1() retain];) is never released inside the dealloc method.

I post the memory-leaks i have found. I highly recommend that you check if the provided code still works with the rest of your code.

memory-leak in class "DKDeferredURLConnection":
add "[decodeFunction release];" into the "dealloc"-method

three memory-leak in class "DKJSONServiceProxy" in the "- (id):(NSArray *)args"-method.
This method should call the autorelase-method of the "d"-object and the user should retain the returned object:

replace

    NSString *post = [[[SBJSON alloc] init] stringWithObject:methodCall error:&error];

with:

    SBJSON *json = [[SBJSON alloc] init];
NSString *post = [json stringWithObject:methodCall error:&error];
[json release];

and replace

               DKDeferred *d = [[DKDeferredURLConnection alloc] 
               initWithRequest:req pauseFor:0.0f
               decodeFunction:[callbackP(_decodeJSONResonse) 
                               composeWith:callbackP(_decodeJSON)]];

with:

                                     DKDeferred *d = [[[DKDeferredURLConnection alloc] 
                 initWithRequest:req pauseFor:0.0f
                 decodeFunction:[callbackP(_decodeJSONResonse) 
                                 composeWith:callbackP(_decodeJSON)]] autorelease];

and release the request:

            [req release]; 

before you return the url-connection.

memory leak in File "DKDeferred-JSON.h" in the "id _decodeJSON(id results)"-method.

replace:
id ret = [[[SBJSON alloc] init]
objectWithString:objstr error:&error];
with:
SBJSON *json = [[SBJSON alloc] init];
id ret = [json objectWithString:objstr error:&error];
[json release];

memory-leak in class "DKCallback" in the "- (DKCallback *)composeWith:(DKCallback *)other"-method.

replace:
return [[DKCallbackComposition alloc] initWithF:self andG:other];
with:
return [[[DKCallbackComposition alloc] initWithF:self andG:other] autorelease];
