Hey all, I've been building an app for a client and part of it uses Apple's TopSongs sample app to download data on another thread. I finally got enough done to start testing that part and found >1000 leaks!!! A closer look at the leaks made me check TopSongs for leaks, since none of the my methods were in leaks report. Running TopSongs ...
Hi, I have a strange behaviour. I am using a rather heavy page (4000 nodes) meant to display a dispatch system for delivery operations. Every 30 sec. I am refreshing with jquery, the list of operations (3000 nodes over 4000). It works perfectly well, but... each time, the memory of both firefox and chrome is increasing by 3 to 6ko. Of c...

There's a bug in delphi 6 which you can find some reference online for when you import a tlb the order of the parameters in an event invocation is reversed. It is reversed once in the imported header and once in TServerEventDIspatch.Invoke. you can find more information about it here: http://cc.embarcadero.com/Item/16496 somewhat rela...
This is kind of a follow-up to a question I posted last week: http://stackoverflow.com/questions/2429056/simple-jquery-ajax-call-leaks-memory-in-ie I love the jquery syntax and all of its nice features, but I've been having trouble with a page that automatically updates table cells via ajax calls leaking memory. So I created two simple...
Do these types of memory leaks have fixed names? ...
I've done a lot of research on when it's correct to release things, but it's all confusing to me. I think sometimes the Leaks program is off. Anyway... background is a UIImageView background.image = [UIImage imageNamed:@"greenbackground.png"]; Do I have to release background? I never alloced it and it's not set as a property, so I...
I'm trying to track down some peculiar memory behavior in my Cocoa desktop app. My app does a lot of image processing using NSImage and uploads those images to a website over HTTP using NSURLConnection. After uploading several hundred images (some very large), when I run Instrument I get no leaks. I've also run through MallocDebug and ...
I tried this: .... vector<players*> player; for (int i = 0; i<10; i++) { player.push_back(new players()); } ... And I wonder if I need to free memory for the vector? If so, how? ...
We have a .net 2.0 application. In the .aspx page we are calling the java applet using . This applet is calling the Acordex Image viewer. In the production environment users are facing "out of memory" or "insufficient memory" issues when users try to open the image or magnify an image in Acordex viewer. Strangely when the users logout an...
Hy guys, I am currently trying to implement some custom ILifecycles for StructureMap. Depending on events the lifecycle is associated with all object should be removed from the lifecycle. Here is the registration for an object. I get a lifecycle from my manager for a plugintype and concretetype using a scope to determine the lifecycle....
Hi, in my application, a RSS reader, I get memory leaks that I can't fix because I can't understand from where they come from. Here is the code pointed out by Instruments. -(void) readArticlesFromDatabase { [self setDatabaseInfo]; sqlite3 *database; articles = [[NSMutableArray alloc] init]; if(sqlite3_open([databasePath UTF8String]...
I'm fairly new to Cocoa and Objective-C. Currently I'm developing a fairly basic application to test my knowledge and put some of the stuff I've been reading about into practice. Everything is working, but Leaks reports a number of issues. None of these leaks seems to be directly applicable to code that I've written (I have read and tr...
I've created a graphing application that calls a web service. The user can zoom & move around the graph, and the program occasionally makes a decision to call the web service for more data accordingly. This is achieved by the following process: The graph has a render loop which constantly renders the graph, and some decision logic which...
Certainly we should call Dispose() on IDisposable objects as soon as we don't need them (which is often merely the scope of a "using" statement). If we don't take that precaution then bad things, from subtle to show-stopping, might happen. But what about "the last moment" before process termination? If your IDisposables have not been...
Hi folks, How can i look every user session variable on IIS Application Server. This issue is to find a biggest session variable on my application to find a leak because my session timeout requirement is too high. ...
Unfortunately the solutions have not worked yet; setting result.values pointer to 0 doesn't actually relieve the memory usage. I've also tried free(result.values) in place of that, but that is not desired as that deletes my string. Edit 2: I'll try writing a stack destructor. Edit 3: Gotcha. Thanks DeadMG, writing a destructor that fre...
Lets say I have something like... void foo() { char c[100]; printf("this function does nothing useful"); } When foo is called, it creates the array on the stack, and when it goes out of scope, is the memory deallocated automatically? Or is c destroyed, but the memory remains allocated, with no way to access it/get it back exce...
I'm trying to replace a DOM element (a div) using Prototype's Element.replace() operation. It seems to do the replacement OK, but leaks a single DOM node in the process. I checked this with sIEve; all but one of the existing DOM elements is freed by the innerHTML="" bit. This is in turn leaking memory, which I can't afford in a long-runn...
This is the header: @interface ForumBrowserAppDelegate : NSObject <UIApplicationDelegate> { ForumSelection *forumSelection; UIWindow *window; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet ForumSelection *forumSelection; (I'm not sure what the nonatomic does, is it something to do w...
