[Bug 201302] New: Crash due to memory access problem on Mac OS X

https://bugs.kde.org/show_bug.cgi?id=201302

           Summary: Crash due to memory access problem on Mac OS X
           Product: digikam
           Version: 1.0.0-beta2
          Platform: Fink Packages
        OS/Version: other
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.0.0-beta2 (using KDE 4.2.0)
Compiler:          gcc 4.0.1
OS:                OS X
Installed from:    Mac OS X (Fink) Packages

After Gilles worked out all the kinks with compiling on Mac OS X, I can
successfully compile most, if not all, recent SVN versions of digiKam. However,
unless one has installed version 4.2.0 (not 4.2.4) of all KDE components using
MacPorts, digiKam & dngconverter will never launch due to something wrong with
"kdelibs. Your core libs are corrupted." (I'm quoting Gilles there!).

Luckily, I went back to a backup of my OS that had an older Darwin Ports
installation. This allowed me to install version 4.2.0 of all KDE stuff on OS
X.

Now, dngconverter works fine. digiKam works fine for a little bit, until it
crashes while trying to load some thumbnails or an image. Here is the relevant
backtrace:

Program received signal EXC_BAD_ACCESS, Could not access memory.

If you're having trouble reading the error messages above, take a look at this
.txt file of the error messages here:

http://staff.washington.edu/rjsanyal/Photography/digiKam/digiKam_1.0.0-beta2_ErrorOnMacOSX.txt

Any ideas?

Many thanks in advance,

Yes, it's in libpgf.

Run digiKam into valgrind and post trace here.

Look into HACKING file for details about memory leak and valgrind.

Thanks Gilles.

Here's a link to the Valgrind output (it's really long):
http://staff.washington.edu/rjsanyal/Photography/digiKam/digiKam_ValgrindOutput.txt

But before you get too far, I just realized that when I ran 'sudo port -d
selfupdate', MacPorts updated all my KDE installations from 4.2.0 to 4.2.4.
Automatically. Maybe that's where the trouble is.

So tonight I'll reinstall my OS backup and retry installing 4.2.0 versions of
everything & see if the problem lies there.

Let me know if you can make any sense of the valgrind output and if it helps.

Cheers,
Rishi

From Rishi by private mail :

I reinstalled my OS so I could get 4.2.0 versions of all KDE stuff,
compiled the newest SVN version of digiKam, and then used Valgrind to
trace the memory leak. See the .txt file linked below for Valgrind
output:

http://staff.washington.edu/rjsanyal/Photography/digiKam/digiKam_ValgrindOutput-2.txt

Basically, Valgrind says "The 'impossible' happened"...

GDB backtrace gives the same stuff I posted above in the first post...
i.e. something wrong with libpgf.

Trying to compile older versions of digiKam now to see if the problem goes
away.

Does this help?

Many thanks,
Rishi

Gilles,

I tried the most recent SVN version of digiKam... would 1.0.0-beta3 be any
different?

From libpgf, i think no. But a lots of digiKam part have been patched. It's
always clean to use current svn especially in beta stage, because a lots of
bugs are fixed...

Well, I can confirm that revision 983830 of digiKam (around the June 19, 2009
SVN commit of digiKam) compiles and runs beautifully on my Mac OS X with all
4.2.0 KDE components.

No memory leaks.

I was able to check out and compile revision 983830... it all broke somewhere
after that... I'm not sure exactly at which revision it broke... I guess I
could keep trying a bunch of revision between 983830 and the current version...
but that would require a lot of trial & error :)

Again, as soon as I update my ports such that KDE components become 4.2.4,
everything becomes broken.

Oh, I forgot, even though I hacked LensFun to compile on Mac, and even though
the cmake command gives me output that says 'liblensfun library found...
YES'... I can't seem to find anything LensFun related in the contextual menus
when running digiKam :(

Cheers,
Rishi

I'm sorry, I guess what I was asking was: isn't the most recent SVN version of
digiKam basically the same as 1.0.0-beta3?

P.S. Even tho LensFun isn't showing up, liquid rescale works beautifully! Cool!

Revision #983830 has nothing special with libpgf :

http://websvn.kde.org/?view=rev&revision=983830

Also, excepted this commit in libpgf :

http://websvn.kde.org/?view=rev&revision=990017

all other are post #983830 :

http://websvn.kde.org/trunk/extragear/graphics/digikam/libs/3rdparty/libpgf/

So i cannot where is the problem in libpgf...

Looking your last valgrind backtrace, a lots of memory leak can be seen in
marblewidget. I recommend to uninstall libmarblewidget and recompile digiKAm
without it (there is no yet an option to disable marble support with cmake
script...

Rishi,

Take a look below of private mail from Christoph (libpgf team):

-------------------------------------------------------------------------------

Hi Gilles

In platform.h is the symbol __BIGENDIAN__ defined for Mac OS. On Intel Macs
this symbol must not be defined. Recently I got some messages that with this
minor change it runs well on Intel Macs.

If the system runs on an older PowerPC Mac then I first have to organize such a
machine and to do some tests, but at the moment I'm on holiday.

Christoph

Gilles,

I did what you suggested, uninstalled libmarblewidget, made sure that digiKam
compiled without it, then recompiled and ran the software. Unfortunately, it
crashes right away. Here's the relevant backtrace, again pointing to libpgf:

I can do valgrind if you want me to... Let me know.

Gilles,

Great! I tried Christoph's suggestion, re-enabled libmarblewidget, and
recompiled the most recent SVN version (beta4) of digiKam.

It works! No crash as of yet.

So... it looks like problem solved... for now :)

Thanks very much for being so prompt & resourceful!
Cheers,
Rishi

Lens Corrections are showing up in any of the contextual menus...

Did you move them/disable them?

No. it's on Enhance/Lens/Auto-Correction entry from editor menu.

Interesting... It used to be in the Enhance menu on my Mac, but now these are
the only items available in under the 'Enhance' menu:

Sharpen
Blur
Red Eye
Hot Pixels
In-painting
Noise Reduction
Restoration

Both the beta4 and the revision 983830 only show these items in then Enhance
menu... any idea what is going on?

Look if files in this folder are compiled :

http://websvn.kde.org/trunk/extragear/graphics/digikam/imageplugins/lenscorrection/autocorrection/

The root folder named lenscorrection is the plugin. it include 3 tools in one.
Looking your menu, this one is not installed on your system, or is not loaded
at startup

run digiKam from the console and post the trace here.

Created an attachment (id=35711)
 --> (http://bugs.kde.org/attachment.cgi?id=35711)
endianess destection using Qt4 flags

Rishi,

For libpgf endianess problem, i have a patch which use Qt4 flags. This cannot
be used in standard libpgf code, but at least it must fix the problem at this
moment.

Please, test and report...

Or do I have to apply a diff patch?
