Hi, I'm using a struct like this: define struct _Fragment{ int a; char *seq; }Fragment; I want to initialize the struct, and using the malloc() method return a dynamic memory like this Fragment *frag=malloc(10*sizeof(Fragment)); Then I would using the frag pointer like this: frag->seq="01001"; Then the problem occurs...
While playing with memory profiling in delphi, although it applies to any language I've found some terms about used memory which I don't completely understand. Could someone explain (or refer to a good document or manual) the meaning of the following terms? Working set size Pagefile used Committed memory Uncommited memory Private Usage...
If I have a derived class with multiple bases, each this pointer for each base will be different from that of the derived object's this pointer, except for one. Given two types in an inheritance hierarchy, I'd like to detect at compile time whether they share the same this pointer. Something like this should work, but doesn't: BOOST_STA...
While monitoring our application in Perf Mon I noticed that the % of Time In GC is anywhere from 20 - 60% while our application is performing a long running process (varies between 30 seconds to 1.5 minutes). This seems a bit excessive to me. This raises two important questions. Am I correct that this excessive? Routes I can take to ...
This question has been puzzling me for a long time now. I come from a heavy and long C++ background, and since I started programming in C# and dealing with garbage collection I always had the feeling that such 'magic' would come at a cost. I recently started working in a big MMO project written in Java (server side). My main task is to...
A big reason why I use OOP is to create code that is easily reusable. For that purpose Java style interfaces are perfect. However, when dealing with C++ I really can't achieve any sort of functionality like interfaces... at least not with ease. I know about pure virtual base classes, but what really ticks me off is that they force me in...
I came across this question about memory management of dictionaries, which mentions the intern function. What exactly does it do, and when would it be used? To give an example: If I have a set called seen, that contains tuples in the form (string1,string2), which I use to check for duplicates, would storing (intern(string1),intern(stri...
Is there any way to know how much memory current web page is using in Firefox? ...
This is an example from The Objective-C 2.0 Programming Language. I was just wondering, in the setter at the bottom, can I use value = [newValue retain] instead of value = [newValue copy] ? @interface MyClass : NSObject { NSString *value; } @property(copy, readwrite) NSString *value; @end // assume using garbage collecti...
I've searched far and wide for its meaning. My guess is that I somehow have a corrupt stack. I get tiny _ free_ list_ add_ ptr on the 16th call of the line that says: NSDateFormatter *theFormatter = [[NSDateFormatter alloc] init]; What is the cause of the problem? Am I correct in thinking that I have a corrupt stack? - (NSStr...
Okay, I have an app that tells me what color of pixel I touched by reading the screen (like a screenshot) after each touch. To retrieve the pixels, I use a method similar to that appearing here. But it seems that after each touch, the image data is still being held on to (and not to mention saving hundreds of unwanted screenshots in my p...
In hopes of trying to avoid future memory leaks in php programs (drupal modules, etc.) I've been messing around with simple php scripts that leak memory. Could a php expert help me find what about this script causes the memory usage to continually climb? Try running it yourself, changing various parameters. The results are interesting....
Hello everyone, I am using VSTS 2008 + .Net 3.5 + C#. I heard the performance of C# List.ToArray is bad since what it does is memory copy for all elements to form a new array. Is that true? thanks in advance, George ...
In C#, does setting a field as readonly reduce memory usage? i.e. DBRepository _db = new DBRepository(); vs readonly DBRepository _db = new DBRepository(); Just curious. Thanks. ...
What is the default Xms and Xmx settings for the Sun JVM (v 1.4*) if those values are not specified at startup? ...
Is there an OS-agnostic Perl module that puts a hard limit on the amount of virtual memory a process can use; e.g. so that the process will be killed if it starts eating up too much memory? I see Apache::SizeLimit, which is obviously Apache specific; and Process::MaxSize, which requires you to call a check function (and also has a hacky...
Hi, I'm looking at revamping our malloc() in our operating system kernel. We currently use dlmalloc, but I'd like a homebrew solution that we can edit without having to work on a thousand-line file. I've decided to look into the slab allocator (Bonwick94) and I believe it's the right choice. So far I understand the concept and am ready...
This question is related to http://stackoverflow.com/questions/1053242/array-of-pairs-of-3-bit-elements This array has 52 pairs (about 40 bytes), and I want to find the first pair before the specified one that has it's values different from 0 (used pair). The obvious solution would be to check each pair < than this one (scan from right t...
