It crash in OpenCV shared lib. Which version you use exactly? Look in Help/Components Info dialog for details.

2.4.6.1 --- just built it along with digikam 3.3.0 cause my old openCV was too old...

Any further advice?  Still making digikam unusable... :(
Comment 5 kshaav 2013-09-23 07:29:06 UTC 
Definitely appears to be a digiKam rather than OpenCV problem. 
I tried going back to OpenCV 2.4.5 and had the same result.
I then rebuilt the 3.3.0 beta along with OpenCV 2.4.5 and it works fine. So, for the time being sticking with the beta. :(

New crash information added by DrKonqi

digikam (3.4.0) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed: Crashes everytime a facetag is added to a photo.

Comment 8 caulier.gilles 2013-11-08 15:34:31 UTC 
kshaav,

Can you check if solution described in bug #325309 solve your problem ?

Gilles Caulier
Comment 9 shaav 2013-12-01 22:33:56 UTC 
Nope, it didn't. Still a problem in 3.5 with OpenCV 2.4.7

The crash does not happen immediately, if it makes a difference. There is a short delay --- under a minute --- in which I can create several facetags (and the facetags ARE being written and retained), but even if I just create one, the crash will happen.

Comment 10 shaav 2013-12-02 07:05:26 UTC 
I have actually actively tried to avoid using any of the automatic face detection and recognition in digikam just because I already have tens of thousands of face tags in my collection and I didn't really trust it to start doing its own thing. But out of curiosity, I tried running the scan on a single album (using "Maintenance") and it crashed immediately too (see below).

Can digikam be built *without* opencv and still do face-tagging? I mean, I would be content to resign myself to manually doing all my tags if I could actually do it without it crashing constantly.

Comment 11 kshaav 2014-01-25 10:52:00 UTC 
FYI

Just finished doing a fresh install of Linux Mint 16. Installed the repository version of digikam (3.4), created a new sqlite db (was using mysql before) from scratch and same problem.
Comment 12 kshaav 2014-01-26 08:58:51 UTC 
I don't know if this is relevant or not --- seems possible...

One of the reasons that I switched to using mysql was that with 60K pictures, I found the sqlite was unbearably slow --- like, create a face tag and it would take 20 to 30 seconds for the name field to pop up and then again when it was actually writing it.  MySQL was running much faster---usable, but not what I would have expected even then.

Now, I've installed OpenSuse as a *virtual machine* and using the sqlite backend, there are nearly the performance issues and I noticed that it's using about 200MB of memory.  On Linux Mint it was using *2GB* of memory... Not having used it on any other OSes, I assumed this was normal...
Comment 13 caulier.gilles 2014-05-16 07:30:43 UTC 
digiKam 4.0.0 is out :

http://www.digikam.org/node/713

Please check if this entry still valid with this new version.

Thanks in advance

Yup, it continues to be a problem.

Comment 16 caulier.gilles 2014-06-11 21:31:34 UTC 
With next digiKam 4.1.0, i fixed libkface to handle all C++ exception (and not only OpenCV exception).

So, at least, digiKam must crash lesser now. If you want to review this entry again, use current implementation from git/master, or wait next 4.1.0 release...

Thanks to update your feedback

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"  :

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

Comment 18 shaav 2014-06-22 23:03:13 UTC 
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.
Comment 19 caulier.gilles 2014-06-23 03:52:28 UTC 
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...

Comment 20 caulier.gilles 2014-06-23 03:57:05 UTC 
I just update libkface revision to 3.1.0 just to be sure to identify right code on your computer...

Comment 21 shaav 2014-06-23 04:16:04 UTC 
I pulled everything from git today.  If I can give you any other info, just let me know. I would LOVE to get this resolved.
Comment 22 caulier.gilles 2014-06-23 05:22:01 UTC 
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.

Comment 23 shaav 2014-06-23 06:15:01 UTC 
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:

Comment 24 caulier.gilles 2014-06-23 06:29:43 UTC 
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.

Gilles Caulier
Comment 25 caulier.gilles 2014-06-23 06:31:46 UTC 
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?
Comment 27 shaav 2014-06-23 22:04:37 UTC 
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.
Comment 28 e.longuemare 2014-06-23 23:12:26 UTC 
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
Comment 29 shaav 2014-06-24 00:25:23 UTC 
>and see if you have SSE3 flag at line flags.

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.

Comment 30 e.longuemare 2014-06-24 06:57:03 UTC 
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

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

I would --- don't know how.
Comment 32 e.longuemare 2014-06-24 07:18:01 UTC 
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 caulier.gilles 2014-06-24 07:40:29 UTC 
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

==> 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...

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

Yes, it is pointing to the 2.4.9 that I built.

All good.

*doh* Over-thinking things... I thought there was a special debugging console or something. Output is:

Also, all good. Works fine.

From the previous console trace:

qUncompress: Z_DATA_ERROR: Input data is corrupted

Sound like data from face database are corrupted (probably due to previous crash). Can you delete database file located at :

~.kde4/share/apps/libkface/database/

mine : [gilles@localhost database]$ ls -l /home/gilles/.kde4/share/apps/libkface/database
total 397020
-rw-r--r-- 1 gilles gilles 406543360 juin  23 14:16 recognition.db

... and try again ?

Comment 39 shaav 2014-06-24 09:35:55 UTC 
Unbelievable. Seems to be fine now. I kinda want to cry.

Thank you both for helping to diagnose that.

Can I perhaps suggest a better handling of this eventuality? I never would have thought to delete this database --- didn't even know it existed. I thought everything was in my digikam folder...
Comment 40 caulier.gilles 2014-06-24 11:43:38 UTC 
Thanks to investigate with us.

Please continue to review Face Management.

I currently working hard on this topic, trying to stabilize code as i can (i'm not original author of this code)...
