Picture where digikam perspectiv-correction crashes

Every time I will change the color-balancing of a picture digikam crashes. There is no crash-information though gdb is installed.

Digikam also crashes but not allways, only with special pictures (s. attachment). 

I am working long with digikam under Linux and it works very well. But now, i am working with Mac it often crashes. Shall I use digikam no more?

Sincerly Detlef Dürr
Comment 1 caulier.gilles 2014-10-27 10:25:20 UTC 
We need a GDB backtrace to hack. Run digiKam into GDB as explained here :

It's impossible to get a backtrace because after generating "qt4-mac
+debug" and "digikam @4.0.0_0 + debug" the digikam crashes directly by
calling the program. By reactivating "digikam @4.0.0_0" the program
starts with "qt-mac + debug".

If the system will not better working, i think I must change my program
for image-handling only using "gimp"

Sincerely
Detlef Dürr

Comment 5 caulier.gilles 2015-05-28 14:32:09 UTC 
Ok, i need to know your color management settings and your ICC profiles files. For these one, please attach .icc files to this report

Gilles Caulier
Comment 6 caulier.gilles 2015-05-29 07:56:01 UTC 
When you said "but always the program crashes by correcting the color", what do you mean by "correcting the color" ? 

Did you use color management settings ?

Did you use a specific tool from editor to change color tonality/brightness/contrast/etc... ?

What do you do exactly in digiKam to crash application ? 

Note your backtrace do not give any information about digiKam source code...

»Color correction« means the menupoint in German »Farbabgleich«. I worked in the following steps:

1. Starting digikam
2. click on 1 picture in the actual album
3. click menupoint  »Bildbearbeitung«
4. Choose the menu point »Farbabgelich«
5. if the program not crashes exactly now, test of lowering blue => crash
6. program crash report…

Sometimes the system also crashes by choosing the menupoint »Anpassung der Perspektive«.

Ok, it's color balance tool.

Go to digiKam/setup dialog, into MICS section and choose QtCurves widget styles.

Try again to check if it's improve stability.

Setting QtCurves doesn’t change the stability. By choosing »color balance« und choosing for »blue« -1 stops the program because of crash

I think that problem is similar than bug #320382, excepted that you crash in this condition.

Can you try to reproduce the problem from this file ?

Thats my reproduction of the file #320382 with one of my pictures. The picture itself will not be corrupted (see the right picture in the appendix (I have the picture scaled to a small version and copied into the screenshot of digikam after selecting "Aspect Ratio Crop«, so I can  send it to you) of my answer. The left small picture shows an undiscernible rightangle an there is no information for the cropping.

Comment 15 Detlef 2015-09-15 13:05:30 UTC 
Today I have installed digikam 4.13.0 and it runs but not in all possibilities. If i click in picture editing the menue-option "color-management", then then color-management opens, but by clicking on 1 color to change, by example the color "blue" gving a "-1" in direction "yellow" digikam crashes.

The procedure is reproducible. See the crash-backtracking.

Hallo,

I also load the 5.0.0 Package und opened the Image editor - and all is well done. But when I opened the Color Management and tried to use the botton the change the Color blue to yellow the Programm crashes.

This must be corrected. Sincerely

Comment 20 caulier.gilles 2016-07-02 20:08:31 UTC 
Yes, now it's reproducible with 5.0.0, and a simple JPEG image.

Color Management is not enable.

Editor is open without no thumbbar. Only Color balance tool is open and cursor is just moved from Blue to Yellow. 

digiKam crash inside the Chanels Mixer algorithm.

Comment 24 caulier.gilles 2016-07-03 06:57:40 UTC 
Maik,

As i can see, Color Balance is the only editor which crash quickly like this. Very strange. What's is too much different in this tool to see this behavior...

Perhaps a race condition with signal/slots.

Also, why we don't see any problem under Linux (I don't checked Windows)

Gilles
Comment 25 Maik Qualmann 2016-07-03 07:07:30 UTC 
Gilles,

is there a difference between 8 bit or 16 bit images?
It works well under Windows.

Comment 27 caulier.gilles 2016-07-03 07:15:18 UTC 
As i can see, Color Balance with all setings to 0 is processed well when tool is open in Image Editor.

Only when settings is changed, a new processing is done and it crash imediatly.

Gilles,

please test this patch for fun.

No difference. Crash is always here...

Comment 32 caulier.gilles 2016-07-03 12:01:13 UTC 
Note the crash appear also when you touch another color balance settings, not only B/Y

Comment 34 caulier.gilles 2016-07-03 12:29:28 UTC 
MAik,

The crash do not appear to be in algorithm itself. With my CLI color balance test tool, it do not crash and color changes are well applied :

The only difference is that filter is forked in a dedicated thread. Perhaps it's the problem.

In case of the problem will be relevant of widget style (as size of preview to render image is not calculated properly), i use Fusion style.

Maik,

I go back with this problem under OSX.

This time, i used llldb CLI debuguer from XCode which is very similar than GDB for GCC but here for Clang compiler.

The backtrace while running Color Balance tool when yellow settings is changed is below :

Maik,

I'm back to this problem under OSX which still valid and always not resolved.

When i triaging bug, i discovered one similar entry under Linux :

https://bugs.kde.org/show_bug.cgi?id=377517

Look well. It's not exactly Color Balance tool, but ChanelMixer used in BW converter.

Sound like there is a problem with Data alignment in memory. This is what's you suspected in this file in the past. Right ?

cbfilter6.patch

Gilles,

can you test this patch when you have time? There is only one technical test, the patch is not intended to definitively solve the problem.

Maik
Comment 44 caulier.gilles 2017-04-19 19:58:27 UTC 
Ok, i will test it while this week end. I need to re-install whole Macports on my lead MacBook Pro to test after compiling.

new MacOS backtrace with 6.0.0

I still unable to understand the reason of the crash. It happen imediately when Balance tool appears in editor
Comment 47 caulier.gilles 2018-05-18 12:03:36 UTC 
Another interresting info : the emory info under MacOS cannot be discovered for Dimg allocation :

In fact, it miss code for MacOS in this implementation :

https://cgit.kde.org/digikam.git/tree/core/libs/kmemoryinfo/libstatgrab/kmemoryinfo_backend.cpp

Perhaps this is the origin of the problem under MacOS, and certainly other one outside Balance tool.

Great. Confirmed. This fix the problem...

Do you have any idea why this fix is mandatory under MacOS.

Sound like the stack used to allocate channel buffers is limited. Right ?

Gilles
Comment 50 Maik Qualmann 2018-05-19 08:16:27 UTC 
Right Gilles,

In contrast to the main thread, the threads under MacOS are assigned significantly less stack memory.
