  • Stack Overflow problem in a recursive program in C

    - by Adi
    Hi all, I am getting a stack overflow in one of the recursive functions i am running.. Here is the code.. void* buddyMalloc(int req_size) { // Do something here return buddy_findout(original_index,req_size); // This is the recursive call } void *buddy_findout(int current_index,int req_size) { char *selected = NULL; if(front!=NULL) { if(current_index==original_index) { // Do something here return selected; } else { // Do Something here return buddy_findout(current_index+1,req_size); } } else { return buddy_findout(current_index-1,req_size); } } Consider the initial value of index to be 4. and it first do index-1 till it reaches 0 index. and then it comes back to index 4 by incrementing..This is wht i want to implement. But it gives a stack overflow with memory map in the command prompt : Here is the output from my shell : * glibc detected * ./473_mem: free(): invalid pointer: 0x00c274c0 * ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6[0xb50ff1] /lib/tls/i686/cmov/libc.so.6[0xb526f2] /lib/tls/i686/cmov/libc.so.6(cfree+0x6d)[0xb557cd] ./473_mem[0x8048b44] ./473_mem[0x8048b74] ./473_mem[0x8048b74] ./473_mem[0x8048944] ./473_mem[0x8048c87] ./473_mem[0x8048d31] ./473_mem[0x8048f79] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6)[0xafcb56] ./473_mem[0x8048671] ======= Memory map: ======== 0017c000-00198000 r-xp 00000000 08:01 5224 /lib/libgcc_s.so.1 00198000-00199000 r--p 0001b000 08:01 5224 /lib/libgcc_s.so.1 00199000-0019a000 rw-p 0001c000 08:01 5224 /lib/libgcc_s.so.1 00260000-00284000 r-xp 00000000 08:01 1927 /lib/tls/i686/cmov/libm-2.10.1.so 00284000-00285000 r--p 00023000 08:01 1927 /lib/tls/i686/cmov/libm-2.10.1.so 00285000-00286000 rw-p 00024000 08:01 1927 /lib/tls/i686/cmov/libm-2.10.1.so 006cd000-006e8000 r-xp 00000000 08:01 6662 /lib/ld-2.10.1.so 006e8000-006e9000 r--p 0001a000 08:01 6662 /lib/ld-2.10.1.so 006e9000-006ea000 rw-p 0001b000 08:01 6662 /lib/ld-2.10.1.so 00aa9000-00aaa000 r-xp 00000000 00:00 0 [vdso] 00ae6000-00c24000 r-xp 00000000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c24000-00c25000 ---p 0013e000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c25000-00c27000 r--p 0013e000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c27000-00c28000 rw-p 00140000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c28000-00c2b000 rw-p 00000000 00:00 0 08048000-0804a000 r-xp 00000000 00:14 2176 /media/windows-share/OS/Project2/473_mem 0804a000-0804b000 r--p 00001000 00:14 2176 /media/windows-share/OS/Project2/473_mem 0804b000-0804c000 rw-p 00002000 00:14 2176 /media/windows-share/OS/Project2/473_mem 08483000-084a4000 rw-p 00000000 00:00 0 [heap] b7600000-b7621000 rw-p 00000000 00:00 0 b7621000-b7700000 ---p 00000000 00:00 0 b7716000-b7819000 rw-p 00000000 00:00 0 b7827000-b782a000 rw-p 00000000 00:00 0 bfb96000-bfbab000 rw-p 00000000 00:00 0 [stack] Aborted Thanks in advance adi

  • Remove an element from an xml File using jdom

    - by Llistes Sugra
    I have a 300 KB xml file with 70 elements in it. I need to be efficient upon removing one of the root's elements. What is the best approach? Should I detach the element in memory, save it and overwrite it by moving it? Is there a better option? I like org.jdom but any improvement is welcome

  • Populate Multiple PDFs

    - by gmcalab
    I am using itextsharp to populate my PDFs. I have no issues with this. Basically what I am doing is getting the PDF and populating the fields in memory then passing back the MemoryStream to be displayed on a webpage. All this is working with a single document PDF. What I am trying to figure out now, is merging multiple PDFs into one MemoryStream. The part I cant figure out is, the documents I am populating are identical. So for example, I have a List<Person> that contains 5 persons. I want to fill out a PDF for each person and merge them all into one, in memory. Bare in mind I am going to fill out the same type of document for each person. The problem I am getting is that when I try to add a second copy of the same PDF to be filled out for the second iteration, it just overwrites the first populated PDF, since it's the same document, therefore not adding a second copy for the second Person at all. So basically if I had the 5 people, I would end up with a single page with the data of the 5th person, instead of a PDF with 5 like pages that contain the data of each person respectively. Here's some code... MemoryStream ms = ms = new MemoryStream(); PdfReader docReader = null; PdfStamper Stamper = null; List<Person> persons = new List<Person>() { new Person("Larry", "David"), new Person("Dustin", "Byfuglien"), new Person("Patrick", "Kane"), new Person("Johnathan", "Toews"), new Person("Marian", "Hossa") }; try { // Iterate thru all persons and populate a PDF for each foreach(var person in persons){ PdfCopyFields Copier = new PdfCopyFields(ms); Copier.AddDocument(GetReader("Person.pdf")); Copier.Close(); docReader = new PdfReader(ms.ToArray()); Stamper = new PdfStamper(docReader, ms); AcroFields Fields = Stamper.AcroFields; Fields.SetField("FirstName", person.FirstName); } }catch(Exception e){ // handle error }finally{ if (Stamper != null) { Stamper.Close(); } if (docReader != null) { docReader.Close(); } }

  • Should I worry about circular references in Python?

    - by bodacydo
    Suppose I have code that maintains parent/children structure. In such a structure I get circular references, where child points to parent and parent points to child. Should I worry about them? I'm using Python 2.5. I am concerned that they will not be garbage collected and the application will eventually consume all memory. Thanks, Boda Cydo.

  • Benefit of using multiple SIMD instruction sets simultaneously

    - by GenTiradentes
    I'm writing a highly parallel application that's multithreaded. I've already got an SSE accelerated thread class written. If I were to write an MMX accelerated thread class, then run both at the same time (one SSE thread and one MMX thread per core) would the performance improve noticeably? I would think that this setup would help hide memory latency, but I'd like to be sure before I start pouring time into it.

  • Simple Fundamental Algorithm Question, binary tree traversal

    - by Ben
    I'm trying to explain to non-computer science major student with many questions. (1)What traverses tree? Is it just logic or actual on off switch generates 1s and 0s traveling the circuit board? where is this tree and node exists CPU/Memory in between? (2)If it is 1s and 0s HOW the circuits understand the line for example p=p.getLeft(); I said search the google or wiki.

  • Caveats of select/poll vs. epoll reactors in Twisted

    - by David
    Everything I've read and experienced ( Tornado based apps ) leads me to believe that ePoll is a natural replacement for Select and Poll based networking, especially with Twisted. Which makes me paranoid, its pretty rare for a better technique or methodology not to come with a price. Reading a couple dozen comparisons between epoll and alternatives shows that epoll is clearly the champion for speed and scalability, specifically that it scales in a linear fashion which is fantastic. That said, what about processor and memory utilization, is epoll still the champ?

  • PHP: optimum configuration storage ?

    - by Jerome WAGNER
    Hello, My application gets configured via a lot of key/values (let's say 30.000 for instance) I want to find the best deployment method for these configurations, knowing that I want to avoid DEFINEs to allow for runtime re-configuration. I have thought of - pre-compiling them into an array via a php file - pre-compiling them into a tmpfs sqlite database - pre-compiling them into a memcached db what are my options for the best random access time to these configuration (memory is not an issue) ? Thanks Jerome

  • How to share classes between DLLs

    - by Jamie Hale
    I have an unmanaged Win32 C++ application that uses multiple C++ DLLs. The DLLs each need to use class Foo - definition and implementation. Where do Foo.h and Foo.cpp live so that the DLLs link and don't end up duplicating code in memory? Is this a reasonable thing to do?

  • What is an Entity? Why is it called Entity?

    - by rkrauter
    What is the deal with Entities (when talking about the Entity Framework)? From what I understand, it is pretty much an in memory representation of a data store like sql tables. Entities are smart enough to track changes and apply those changes to the data store. Is there anything more to it? Thanks in advance.

  • Garbage collection in Perl

    - by srikfreak
    Unlike Java, Perl uses reference count for garbage collection. I have tried searching some previous questions which speak about C++ RAII and smart pointers and Java GC but have not understood how Perl deals with the circular referencing problem. Can anyone explain how Perl's garbage collector deals with circular references? Is there any way to reclaim circular referenced memory which are no longer used by the program or does Perl just ignores this problem altogether?

  • Differnce between linux write and sendfile syscall

    - by JosiP
    Hi Im programming webserver (C), which should send big files. My question is: What are the main differneces in two syscalls: write and sendfile. Does sendfile depends on size of socket system buffer ? I noticed that write often writes less then i requested. For example, if got many requests for one file: should i open it, copy into memory and use 'write', or maybe i can do 'sendfile' for each client ? thx in advance for all answers

  • How to simulate a USB drive

    - by rursw1
    Hi all, Is it possible to simulate a USB drive with software only? I mean, for example, to expose a local memory space to the OS so the device manager will recognize it as a USB device. I'm not familiar with hardware implementation, but I'm sure that it is possible somehow to emulate the USB protocol. I began with this book - USB Design By Example. Can anyone please give me additional references to begin with? Thank in advance!

  • WPF Graph Layout Component

    - by Jörg B.
    Does anyone know of or even better.. can wholeheartedly recommend a WPF graph layout component (Microsoft Research had GLEE a while back but it hasn't been updated after 1.0 since 2007 and isn't WPF etc) as seen e.g. in the screenshot below? I've seen yFiles WPF and Lasalle's AddFlow for WPF, but are there any alternatives? (c) Screenshot: RedGate Ants Memory Profiler

  • Google Analytics without ga.js

    - by Andrew
    I can't find anything recent on this. Is there any documentation on how to track with Google Analytics without using ga.js? I want a JS implementation on mobile devices but I don't want to load up 9KB of local memory or use server-side GA. I'm primarily interested only in tracking page views and uniques. Has anyone rolled their own GA implementation?

  • Lazy load pages in UIScrollView

    - by jean
    I have a UIScrollView that contains large images and am using paging to scroll between images. In order to save memory, I am loading only one image before and after the currently visible one and loading/releasing new images after a scroll has completed. The problem occurs when one scrolls quickly and scrollViewDidEndDecelerating is not called. How can I detect continuous scrolling? I could check item location on every scrollViewDidScroll but this seems a bit heavy...

  • Mapkit: Only show annotations in current view

    - by Nic Hubbard
    Instead of loading all annotations that are in my array, I would only like to load the annotations that the user could currently see cased on how far they are zoomed in on the map. So, if the user pans to a place where there are annotations, those would be added, and if they pan away, those would be removed. I assume this would help with memory. Does anyone know how to do something like this? And, is it worth it, or needed?

  • Difference between the List and Enumeration

    - by harigm
    I have a written a method to get all the records and return in the List Type, but I got out of memory error. So I changed return type from List to Enumeration, in the method, instead of ArrayList, uses Vector and return vector.elements at the end of the method. It works without any error. but I did not understand why. Could someone explain Why this Enumeration worked?

  • Use native HBitmap in C# while preserving alpha channel/transparency. Please check this code, it works on my computer...

    - by David
    Let's say I get a HBITMAP object/handle from a native Windows function. I can convert it to a managed bitmap using Bitmap.FromHbitmap(nativeHBitmap), but if the native image has transparency information (alpha channel), it is lost by this conversion. There are a few questions on Stack Overflow regarding this issue. Using information from the first answer of this question (How to draw ARGB bitmap using GDI+?), I wrote a piece of code that I've tried and it works. It basically gets the native HBitmap width, height and the pointer to the location of the pixel data using GetObject and the BITMAP structure, and then calls the managed Bitmap constructor: Bitmap managedBitmap = new Bitmap(bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); As I understand (please correct me if I'm wrong), this does not copy the actual pixel data from the native HBitmap to the managed bitmap, it simply points the managed bitmap to the pixel data from the native HBitmap. And I don't draw the bitmap here on another Graphics (DC) or on another bitmap, to avoid unnecessary memory copying, especially for large bitmaps. I can simply assign this bitmap to a PictureBox control or the the Form BackgroundImage property. And it works, the bitmap is displayed correctly, using transparency. When I no longer use the bitmap, I make sure the BackgroundImage property is no longer pointing to the bitmap, and I dispose both the managed bitmap and the native HBitmap. The Question: Can you tell me if this reasoning and code seems correct. I hope I will not get some unexpected behaviors or errors. And I hope I'm freeing all the memory and objects correctly. private void Example() { IntPtr nativeHBitmap = IntPtr.Zero; /* Get the native HBitmap object from a Windows function here */ // Create the BITMAP structure and get info from our nativeHBitmap NativeMethods.BITMAP bitmapStruct = new NativeMethods.BITMAP(); NativeMethods.GetObjectBitmap(nativeHBitmap, Marshal.SizeOf(bitmapStruct), ref bitmapStruct); // Create the managed bitmap using the pointer to the pixel data of the native HBitmap Bitmap managedBitmap = new Bitmap( bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); // Show the bitmap this.BackgroundImage = managedBitmap; /* Run the program, use the image */ MessageBox.Show("running..."); // When the image is no longer needed, dispose both the managed Bitmap object and the native HBitmap this.BackgroundImage = null; managedBitmap.Dispose(); NativeMethods.DeleteObject(nativeHBitmap); } internal static class NativeMethods { [StructLayout(LayoutKind.Sequential)] public struct BITMAP { public int bmType; public int bmWidth; public int bmHeight; public int bmWidthBytes; public ushort bmPlanes; public ushort bmBitsPixel; public IntPtr bmBits; } [DllImport("gdi32", CharSet = CharSet.Auto, EntryPoint = "GetObject")] public static extern int GetObjectBitmap(IntPtr hObject, int nCount, ref BITMAP lpObject); [DllImport("gdi32.dll")] internal static extern bool DeleteObject(IntPtr hObject); }
