https://bugs.kde.org/show_bug.cgi?id=195610
Summary: Memory leak in image editor Product: digikam Version: unspecified Platform: Ubuntu Packages OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general AssignedTo: [hidden email] ReportedBy: [hidden email] Version: 2.0.10 (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages I'm using Digikam 2:0.10.0-1ubuntu3 (from Ubuntu). After a while, memory usage is creeping up - until Digikam is killed as the system runs out of swap space, usually after two or three dozen pictures. I suspect that something is leaking memory. I have been observing this behaviour all week. My usual processing involves cropping, curves and refocus. Hardware is an AMD Athlon XP with 2 GB RAM. Here are a few outputs of 'ps faux' : With image editor closed, right after launch : USER PID %CPU %MEM VSZ RSS STAT START TIME COMMAND jim 22096 12.8 5.3 353620 110540 Ssl 22:27 0:14 digikam With image editor open, right after launch : USER PID %CPU %MEM VSZ RSS STAT START TIME COMMAND jim 22096 12.4 14.5 541760 299168 Ssl 22:27 0:18 digikam With image editor closed, but after having edited a couple dozen images : USER PID %CPU %MEM VSZ RSS STAT START TIME COMMAND jim 18491 8.2 65.0 1779100 1341752 Ssl 17:36 22:18 digikam After having edited a couple dozen images, with image editor open : USER PID %CPU %MEM VSZ RSS STAT START TIME COMMAND jim 18491 8.2 67.9 1837908 1400848 Ssl 17:36 22:19 digikam While running refocus, right before it got killed for lack of memory : USER PID %CPU %MEM VSZ RSS STAT START TIME COMMAND jim 18491 8.0 76.7 2035800 1583432 Dsl 17:36 23:18 digikam -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

Andi Clemens <[hidden email]> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|general |Image Editor Version|unspecified |0.10.0 --- Comment #1 from Andi Clemens <andi clemens gmx net> 2009-06-08 00:55:24 --- To track down a possible memory leak, we need to know more details. What have you done exactly? Do you use some filters over and over again? Which ones? I have checked the editor, it doesn't leak when just opening images, so it must be some filter. Jean-Marc, please try to reproduce your workflow and tell us which filters you used (it doesn't have to be the exact order of course).

--- Comment #2 from Jean-Marc Liotier <jm liotier org> 2009-06-08 01:02:42 --- I am working on a set of 230 JPEG images from a Canon Eos 50D. I work sequentially, one image after the other, without leaving the image editor. In most cases, the actions are : crop, curves, refocus - in that order. In maybe 15% of the cases, I correct for white balance or saturation, but it is not typical because this set is mostly outdoor portraits. The out of memory kills have if I remember well always happened during refocus - so you might want to put that one on the top of your list of suspects ! -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

--- Comment #5 from Andi Clemens <andi clemens gmx net> 2009-06-12 18:28:52 --- There seems to be a memory leak in the refocus plugin: ==6849== 1,936 bytes in 2 blocks are definitely lost in loss record 473 of 491 ==6849== at 0x402441D: operator new[](unsigned int) (in /usr/lib/valgrind/x86-linux/vgpreload_memcheck.so) ==6849== by 0x410A3AF: Digikam::RefocusMatrix::init_c_mat(Digikam::CMat*, int) (matrix.cpp:102) ==6849== by 0x410A45D: Digikam::RefocusMatrix::allocate_c_mat(int) (matrix.cpp:111) ==6849== by 0x410B214: Digikam::RefocusMatrix::copy_cvec2mat(Digikam::Mat const*, int) (matrix.cpp:360) ==6849== by 0x410B518: Digikam::RefocusMatrix::compute_g(Digikam::CMat const*, int, double, double, double, bool) (matrix.cpp:431) ==6849== by 0x410B5E2: Digikam::RefocusMatrix::compute_g_matrix(Digikam::CMat const*, int, double, double, double, bool) (matrix.cpp:461) ==6849== by 0x4109840: Digikam::DImgRefocus::refocusImage(unsigned char*, int, int, bool, int, double, double, double, double) (dimgrefocus.cpp:153) ==6849== by 0x4109625: Digikam::DImgRefocus::filterImage() (dimgrefocus.cpp:131) ==6849== by 0x4107EF6: Digikam::DImgThreadedFilter::startFilterDirectly() (dimgthreadedfilter.cpp:139) ==6849== by 0x4107FFB: Digikam::DImgThreadedFilter::run() (dimgthreadedfilter.cpp:152) ==6849== by 0x50692CD: (within /usr/lib/libQtCore.so.4.5.1) ==6849== by 0x52786BB: start_thread (in /lib/libpthread-2.10.1.so) It doesn't seem to waste that much memory, but when you never close the editor and work with rather big images, it might get important. Gilles, any idea what is wrong? For me it looks like the memory gets freed again, but I might have overlooked something.

--- Comment #9 from Andi Clemens <andi clemens gmx net> 2009-07-02 23:16:34 --- Jean-Marc, I have fixed some memory leak in the imagescurves: commit 1c8d6a6ec0ca24490b0b96a9e7e51cfe42159196 Author: aclemens <aclemens@283d02a7-25f6-0310-bc7c-ecb5cbfe19da> Date: Mon Jun 15 13:21:37 2009 +0000 fix memory leak in ImageCurves git-svn-id: https://svn.kde.org/home/kde/trunk/extragear/graphics/digikam@982291 283d02a7-25f6-0310-bc7c-ecb5cbfe19da libs/curves/imagecurves.cpp libs/curves/imagecurves.h Since your workflow also includes curves adjustment, it might be one of the sources for your memory leak problem. As I said above, I found another one in the refocus plugin, but unfortunately can't see the actual error. The leak seems to be small though, but when you edit over 200 images, it still might be important. Can you try with the latest SVN version? -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

Andrej Krutak <[hidden email]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[hidden email] --- Comment #10 from Andrej Krutak <andree182 gmail com> 2009-09-26 22:15:46 --- I'm experiencing this bug too - after editing like 10-20 images, digikam uses 1GB ram for no apparent reason... No idea yet, whether the source is the image editor, or the digikam itself - however it made my computer freeze (for out-of-memory reasons, obviously) a couple of times already, so it's quite annoying... After trying valgrind, the non-released memory was 13 MB - after doing some common editing of 3 files.. This seems to not be the problem cause (as that should be more like 50 MB or more). Therefore, either I didn't reproduce the bug with valgrind being used (yet.. digikam is veeeery lazy when valgrinded), or the occupied memory is correctly released when quitting digikam - but is purposelessly allocated after images are closed. I hope I'll find the cause - it's pretty uncomfortable to close digikam after every few edits... :) -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

--- Comment #11 from Andi Clemens <andi clemens gmx net> 2009-09-28 13:28:31 --- Again, what filter did you use? I can not experience this, so there must be a problem in a specific imageplugin. What filetypes are you editing? What dimensions do they have? Is your system 32bit or 64bit?

This seems to not be the problem cause (as that > should be more like 50 MB or more). The 13 MB can come from an unclosed sqlite connection, this typically wastes 8-10 MB on my system... -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

--- Comment #15 from Gilles Caulier <caulier gilles gmail com> 2009-10-29 09:13:23 --- sts, Sound like you didn't use editor plugin here, just you show image as well. Can you run digiKam through valgrind to show memory leak, and reproduce all step in gui until to see memory dysnfuntion appear. Just report all console messages there. Command line to use is below : valgrind --tool=memcheck --leak-check=full --error-limit=no digikam Also, give us more info about your linux box...

--- Comment #16 from Andi Clemens <andi clemens gmx net> 2009-10-29 09:19:17 --- I can confirm this for a long time, and it doesn't seem to be a memory leak, at least in the classical term. Valgrind will show nothing, since at digiKam shutdown all memory is freed, but at runtime it is not. I guess this is due to the fact that IE stay open in the background once used? Every 2 or 3 weeks I look at this bugreport here and try to find the error, but I don't know what is going wrong. Memory usage goes up, but valgrind tells me that all is fine. This one is a nasty bug for sure... -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

--- Comment #17 from Marcel Wiesweg <marcel wiesweg gmx de> 2009-10-29 17:25:36 --- Is the memory listed for the digikam or the xorg process? There is valgrind's "massif" tool to analyze heap allocation over time. If it detects e.g. a peak in memory usage it will give you backtraces from where significant portions of this memory were allocated. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

--- Comment #18 from Johannes Wienke <languitar semipol de> 2010-01-24 17:51:24 --- Ok, I'm just trying to figure this out. Most of the memory allocation happens in DImg::allocate which isn't a big surprise. But I think I got a suspicion what's going on here: 1. Simply viewing images without manipulations is ok, then all memory is cleaned properly. 2. Doing any operation but not saving the image also results in correctly freed memory. 3. Doing any operation and saving the changed image results in more memory use. So there must be something wrong while saving images. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |
