[digikam] [Bug 323361] Crash While Navigating Photos

Gilles Caulier-4
https://bugs.kde.org/show_bug.cgi?id=323361

--- Comment #17 from Gilles Caulier <[hidden email]> ---
Git commit 4662dd94102f8144bc65ce1cb66d6b6cb1d500fd by Gilles Caulier.
Committed on 18/06/2014 at 14:22.
Pushed by cgilles into branch 'master'.

Libkface now depand of last stable OpenCV library version 2.4.9
This prevent internal crash int Cv:Algorithm that we cannot handle in libkface
as exception.
Now, Face Recognition do not crash but still report Exception at training
operations, especially about wrong Cv:Matrix size :

digikam(8673)/digikam (core)
Digikam::DImg::load:"/mnt/data2/photos/GILLES/NEW/Adrien/2010-04-13/20100413_009.jpg"
 :
JPEG file identified
OpenCV Error: Assertion failed (0 <= _dims && _dims <= CV_MAX_DIM) in setSize,
file /mnt/devel/opencv/modules/core/src/matrix.cpp, line 89
digikam(8673)/KFACE: cv::Exception training LBPH:
/mnt/devel/opencv/modules/core/src/matrix.cpp:89: error: (-215) 0 <=_dims &&
_dims <= CV_MAX_DIM in function setSize

It still a problem somwhere, but it's better than previous state.

No change. Built 4.1.0 with OpenCV 2.4.9.  Crashes nearly immediately after
tagging a face.

I was running 3.5.0 in an OpenSuse VM so that I could actually apply
facetags---it worked fine for quite a while and then just recently started
crashing the same way. It's profoundly frustrating.

Not reproducible here.

I play with Face Management a lots and no crash here in all situation.

Do you use libkface compiled with source code from git/master or libkface from
your system ?

I review libkface code indeep recently...

I just update libkface revision to 3.1.0 just to be sure to identify right code
on your computer...

yes, please checkout again code where i add new debug trace on the console.

Run kdebugdialog and digiKam as explained here :

http://www.digikam.org/contrib

Note : turn on KFace debug space to see trace on the console.

I hope I did everything right --- I am not a developer, so I only kind of know
what I'm doing.
Sorry in advance if I messed anything up.

I did a "git checkout" and then rebuilt it. And then making sure everything was
checked in KDebugDialog window, from the KDE bug window:

[digikam] [Bug 323361] Crash While Navigating Photos under Face Management feature

In reply to this post by Shaav

--- Comment #24 from Gilles Caulier <[hidden email]> ---
As i can see in your previous backtrace, it crash into OpenCV clone operation
using SSE3 optimizations for Intel... It can be an upstream problem.

I repeat : here, with an OpenCV 2.4.9 compiled myself, there is no crash. I can
tag face manually or run Face Recognition during a long moment (one hour). In
turn and process fine.

It's clear :

#5  __memcpy_ssse3_back () at
../sysdeps/x86_64/multiarch/memcpy-ssse3-back.S:1548
#6  0x00007f9c99b6e532 in cv::Mat::copyTo(cv::_OutputArray const&) const ()

SSE3 copy crash. I think i don't have enabled this king of optimization here
with OpenCV 2.4.9.

What's about runtime process console trace i ask before (not GDB backtrace)

That does give me some idea why suddenly my VM started having the problem---I
fiddled with some settings recently---but I don't really understand the
implications here... it's an OpenCV problem? It's a fundamental incompatibility
with my computer? (?!)  Is it possible to build digikam without OpenCV at all?
All I want to be able to do is *manually* facetag my pictures.

> What's about runtime process console trace i ask before (not GDB backtrace)

If that's not the backtrace I had before the gdb backtrace, then I'm not sure
how to produce it. The instructions just say: "digiKam trace main debug
statements into the console."  What console?

I was googling to see if there are any ways to turn off the SSSE3 optimization
during compiling or somehow else and I came across this:

http://stackoverflow.com/questions/11507675/memcpy-ssse3-segmentation-fault

It doesn't mean very much to me, but thought it might to you.

Hello,

Should you check if your this by command line:

cat /proc/cpuinfo

and see if you have SSE3 flag at line flags.

Have a look here : https://bugs.kde.org/show_bug.cgi?id=325309.

Greatings,

Eric

I do. As well as everything up to SSE42.

So I rebuilt OpenCV turning off SSE3 (everything above that was already off)
and then rebuilt digikam (is that actually necessary? I wasn't sure if it was
or if you can just rebuild OpenCV).

No change.

I rebuilt OpenCV with all of the SSE options turned off. Rebuilt digikam.

No change.

                 OFF   IF ((MSVC OR CMAKE_COMPILER_IS_GNUCXX) AND (X86 $

Hello,

if you have SSE3 in flags when check with "cat /proc/cpuinfo", this is not
related.

Should you put here the result of "cat /proc/cpuinfo" ?

You should do as Gilles says in comment #22  :  get a trace of runtime.

Greatings,

Eric

So your proc support SSE3, this is not the problem I think (you don't have to
disable SSE at compilation of openCV). You must compile, install openCV before
compile and install digikam.

To get runtime trace (as Gilles asked you in #comment22 :

look here :
https://www.youtube.com/watch?v=uw8FdebrIJs 

and  check things related to digikam and its dependencies. KFACE as Gilles
said.

Then run digikam in a shell and reproduce the crash.

Greatings,

Eric

--- Comment #33 from Gilles Caulier <[hidden email]> ---
If you have disabled SSE support in OpenCV, and recompiled libkface + whole
digiKam (this require to reset cmake cache file to be sure), and if OPenCV
continue to crash in SSE support as previous, well there is a problem in your
way to make whole digiKam with OPenCV.

Are you sure that digiKam and libkface use libopenCV compiled by you and not
system based ?

# ldd /usr/lib64/libkface.so |grep opencv

(0x00007fd6444c9000)

==> you will see that libkface is linked with OpenCV 2.4.*. To be sure that
2.4.9 is used, look where /usr/lib/libopencv_core.so.2.4 symlink point :

# ls -l /usr/lib/libopencv_core.so.2.4
lrwxrwxrwx 1 root root 23 juin  19 19:40 /usr/lib/libopencv_core.so.2.4 ->
libopencv_core.so.2.4.9*

for me, it's my 2.4.9 OpenCV...

lena.jpg test openCV out of digikam

You should check if openCV is right :

look here :
http://thesilenceoflambs.wordpress.com/2012/05/08/install-and-test-opencv-under-fedora-16/

and check openCV alone :
The next part is to test whether openCV can function well.

cd ~/OpenCV-2.4.x/samples/c

sh  build_all.sh

./facedetect  lena.jpg

If an image can pop up,  congratulations!  The library can work well!

Greatings,

Eric

Screenshot of "detect" test tool from libkface in action

libkface provide also a CLI tool to test face detection :

Look this screenshot for details. On the left of "detect" window, the whole
image, on the right, the face region detected...
