memory leak

The MagickWand interface is a new high-level C API interface to ImageMagick core methods. We discourage the use of the core methods and encourage the use of this API instead. Post MagickWand questions, bug reports, and suggestions to this forum.

memory leak

Post by rpatelob » 2017-06-19T06:48:40-07:00

Code: Select all

Version: ImageMagick 7.0.6-0 Q16 x86_64 2017-06-14 http://www.imagemagick.org
Copyright: © 1999-2017 ImageMagick Studio LLC
License: http://www.imagemagick.org/script/license.php
Features: Cipher DPC HDRI OpenMP 
Delegates (built-in): bzlib djvu fontconfig freetype gvc jbig jng jpeg lcms lqr lzma openexr png tiff wmf x xml zlib

I'm using valgrind to check for memory leak and it shows so many errors, I don't know may be I made any mistake or not.
This is the C code.

Code: Select all

#include <stdlib.h>
#include <MagickWand/MagickWand.h>

int main() {
  MagickWand *magick_wand;
  unsigned char blob[921615];

  fread(blob,921615,1,stdin);
  MagickWandGenesis();
  magick_wand=NewMagickWand();
  MagickReadImageBlob(magick_wand,blob,921615);
  MagickWriteImage(magick_wand,"logo.miff");
  DestroyMagickWand(magick_wand);
  MagickWandTerminus();
}
The last line from valgrind is

Code: Select all

ERROR SUMMARY: 82 errors from 82 contexts (suppressed: 0 from 0)
Below is the CLI I used to check

Code: Select all

valgrind --leak-check=yes -v cc -o wand test.c `pkg-config --cflags --libs MagickWand
Valgrind version in my system valgrind-3.11.0

We do not get any errors or leaks:

Code: Select all

-> valgrind --leak-check=yes wand < logo.png

Thanks @magick,

In my system it shows error, is it because of IM version?
It sows weird error. I couldn't able to understood it. Please look at the below output of valgrind.

Re: memory leak

You are checking for memory leaks in the compiler, not ImageMagick. Try this command instead:

Code: Select all

valgrind --leak-check=yes wand < logo.png

Oh thanks!

Code: Select all

int main(int argc, char const *argv[]) {
  MagickWand * wand0;

  MagickWandGenesis();

  wand0 = NewMagickWand();
  MagickReadImage(wand0, "logo:");

  MagickTransformImageColorspace(wand0, GRAYColorspace);

  MagickShadeImage(wand0, MagickTrue, 125.0, 130.0);


  MagickWriteImage(wand0, "output.gif");

  wand0 = DestroyMagickWand(wand0);

  MagickWandTerminus();

  return 0;
}
Now with this code it's showing error on two places MagickTransformImageColorspace and MagickShadeImage.

Code: Select all

You are seeing overhead associated with setting up the OpenMP parallel environment. We can't control that, its part of the libgomp library, not ImageMagick. Or perhaps libgomp has a destructor we can call, but we are not aware of an destructor API call. You can build ImageMagick without OpenMP enabled, just add --disable-openmp to your configure script command-line, build, and reinstall.

Actually I want OpenMP in my production, how do we avoid such leaks? Does OpenMP version creates leak?
and Is it good to ignore such errors in production? Any suggestions please!
