I have created created a windows application which loads flash movies in modal window form by selecting one of the movie from the parent form. What happens is that user can play that movie in auto mode for let's say 20 minutes. I watch the Task manager closely and what happens is my application memory goes on increasing and it never gets...
Segments of memory - BSS, Stack, Heap, Data, Code/Text (Are there any more?). Say I have a 128MB RAM, Can someone tell me: How much memory is allocated for each of these memory segments? Where do they start? Please specify the address range or something like that for better clarity. What factors influence which should start where? ...
Hi All, Something odd is happening with my view controllers. When an applicationDidReceiveMemoryWarning is posted, it removes all views from the stack other than the visible view (a second level view) which is expected behaviour. However, if I then navigate back to the root view, it also has a back button that navigates back to itself. ...
I couldn't find a good title for the question, this is what I'm trying to do: This is .NET application. I need to store up to 200000 objects (between 3KB-500KB) I need to store about 10 of them per second from multiple-threads I use binaryserialization before storing it I need to access them later on by an integer, unique id What's...
Hey all, I have recently been messing around with SFML, a multimedia library. I use C# so naturally I went for the .Net binding, which you can fetch from the SVN in the latest 2.0 version. After a while of messing around I noticed that my application would sometimes hang up when using the Text object, an object used to draw texture font...
Hi, A production server has an application running 24x7, and sometimes it starts consuming near 50% of CPU. I couldn't reproduce it locally, but I did a Memory Dump with adplus. The server has Windows 2008 Server 64bits, .NET 3.5. The application listens to a MSMQ and has a thread pool to execute operations, when I did the memory dump it...
i have been working on a server and it works with 2 programs i made one is the server and one is the error handler and if the main server fails it restarts it. the 2nd program's main way to handle data is by reading the values from the program(because when i was debugging i was filling in the address's), because writeing the values to a ...
Hello, I am programming a game since 2 years ago. sometimes some memory errors (ie: a function returning junk instead of what it was supposed to return, or a crash that only happen on Linux, and never happen with GDB or Windows) happen seemly at random. That is, I try to fix it, and some months later the same errors return to haunt me. ...
I have got a memory leak problem in the example below(u can download the code from the link) http://brandonmeyer.net/projects/SuperPanelDemo/SuperPanelDemo.html Running in Profiler:- What I am trying to do is creating new panels by selecting the Add new panel button. I am selecting option allow Close (check box). (After creating ...
I'm working on a bit of code where I'm attempting to hide some private variables inside closures. The thing is the environment is fairly constrained in terms of memory, so I'm also concerned with keeping the overall footprint of the classes low. What is the impact of using closures to hide private instance variables and methods when com...
I have a BST which is a linked list in C++. How would I delete the whole thing from memory? Would it be done from a class function? ...
I'm using the following basic function which I copied from the net to read a text file public void read () { File file = new File("/Users/MAK/Desktop/data.txt"); System.out.println("Start"); try { // // Create a new Scanner object which will read the data from the // file passed in. To check i...
Hi, Is there a shell command to know about how much memory is being used at a particular moment and details of how much each process is using, how much virtual memory is left etc? ...
I’ve googled quite a bit, but I can’t find information on how variable-length strings are generally implemented in higher-level languages. I’m creating my own such language, and am not sure where to start with strings. I have a struct describing the string type, and then a create function that allocates such a ‘string’: /* A safer `str...
I'm defining a vector as: vector< int, MyAlloc< int> > *v = new vector< int, MyAllooc< int> > (4); MyAlloc is allocating space for only 4 ints. Memory for _M_start, _M_finish, and _M_end_of_storage is being allocated on the heap before the memory for the 4 ints. But who is allocating this memory for _M_start, _M_finish, and _M_end_of_...
I am working with a memory manager that, on occasion, wants to defragment memory. Basically, I will go through a list of objects allocated by the memory manager and relocate them: class A { SomeClass* data; // This member is allocated by the special manager }; for(... each instance of A ...) a.data = memory_manager.relocate(a.da...
I'm working on integrating rLog with our code base, and I'm noticing a problem on Windows that I don't have on linux. In a header file I have a static variable that gives me a "verbose" logging channel (one up from debug basically), defined thusly: static RLogChannel *rlog_verbose = DEF_CHANNEL("verbose", Log_Debug); There's no probl...
It is general practice to check for NULL (whether memory is successfully allocated) after a malloc, some thing like void *ptr = malloc(10); if (ptr) { // do some thing usefull } else { // no memory. safely return/throw ... } with memory overcommit enabled in kernel, is there a chance of getting NULL. Should i follow the practice o...
Hello. I'm in the process of porting an application originally in java to cocoa, but I'm rewriting it to make it much better, since I prefer cocoa a lot anyway. One of the problems I had in the application, was that when you uploaded images to it, I had the images created, (as say an NSImage object) and then I just had them sitting in ...
Lets consider two almost identical codes: First for (int k=0;k<1000;k++) { for (int i=0;i<600;i++) { for (int j=0;j<600;j++) { tab[i][j] = i *j; } } } Second for (int k=0;k<1000;k++) { for (int i=0;i<600;i++) { for (int j=0;j<600;j++) { t...
