Description Vardhman 2006-02-10 07:06:13 UTC
Version:           0.8 SVN checkout (using KDE KDE 3.5.0KDE 3.4.2KDE 3.4.2)
Installed from:    Fedora RPMsFedora RPMsFedora RPMs
Compiler:          GCC 3.3 
OS:                Linux

I have been using Kipi-camera Download from Digikam for long time and was quite satisfied until I today. I am not able to find out reason for Digikam crashing so many times all of a sudden. The new thing was probably the huge amounts of data including big movie files of sizes around 11-15 MB or so.
Camera Model Dx7590 (Not in list of supported models, but worked quite well)

The first time my PC froze so bad that I had to reboot.
The second time I started downloading digikam crashed after moving around 27%
Next time I started being careful, I would select only some of the photos and downloading them, that was successful, now when I delete those photos and then again select some photos for downloading, I will get error "Cannot download file XXXXX.JPG", which implies camera being disconnected (which was also the mesg on the console "gpa_port_write/read: Connection timed out". Which means that once the delete option is being used the camera is disconnected ?
Once this kind of error comes, what needs to be done is to go to the Camera menu and start again. Sometimes when even that failes then I had to restart my camera.

I think PC freezing because of Digikam is a real bad thing, Crash of Digikam is much less severe but bad too. Kipi-plugins etc should not crash the host app IMHO.
Comment 1 Vardhman 2006-02-10 07:08:54 UTC
This Bugzilla wizard doesn't allow me to put KDE version at 3.3 (Won't allow me to proceed if I say lesser than 3.4). So I had to put KDE 3.5 though the actual version of KDE was 3.3, but I think it hardly matters, I have had almost the latest Digikam, the libs and also the kipi-plugins from SVN almost 2 month ago at max.
Comment 2 caulier.gilles 2006-04-03 15:02:53 UTC
Are you takling about kipi camera interface plugin or digiKam camera interface ? Note kipi camera interface plugin  is always disable in digiKam !!!

Gilles Caulier
Comment 3 Vardhman 2006-04-03 15:34:18 UTC
I am taking about the one that comes from the Cameras option in digikam menubar. I recently had more problem with the same. It seems like downloading large video files is a problem, not very sure. It worked sometime and sometimes it fails..
Comment 4 caulier.gilles 2006-04-03 16:33:14 UTC
Your camera model is a Gphoto2 or a "Mounted Camera" ?

Gilles Caulier
Comment 5 Vardhman 2006-04-03 16:46:23 UTC
Its a USB PTP camera. So I guess it means Gphoto2 camera.
Comment 6 caulier.gilles 2006-04-11 08:08:50 UTC
ok have you a gdb backtrace of crash. You need to compile digiKam using full debug information.

Also i suspect a memory leak in camera gui. Can you check this point using valgrind ? (look in HACKING file from svn the right options to use)

Thanks in advance

Gilles

Vardhman,

I have tested PTP mode with my Dynax 5D camera. Here valgrind report indeep memory problems into PTP gphoto driver during initialization :

Comment 8 Vardhman 2006-04-11 09:37:38 UTC
Gilles,
 I was not following this bug anymore, I guess the last time I updated my
kipi-plugins and other libs things seems to be fine. The video download etc
is also fine. I m not sure how I can actually reproduce the bug. :( may be
for time being you can set this bug fixed.

Comment 9 Marcus Meissner 2006-04-11 09:47:28 UTC
Last time I checked valgrind is not tracking the usb ioctls correctly, so these might be irregular errors.

If you get crashes, please post a gdb backtrace.
Comment 10 caulier.gilles 2006-04-11 09:57:18 UTC
Vardhman, 

I have fixed a little uninitialized value in camera controler witch can give unpredectible result to get Exif metadata from gphoto2 driver. Typically, Exif data are passed to camera controler like a bytes array, and the array size is uninitilaized before to test it. If there is exif data, this is not a problem because the size is updated by gphoto2, but if there is no exif data, the size is uninitialized (typically the memory content initialized by compiler). This is can be dangerous (:=))

Now the size in initialized to 0 before use it in all cases.

Gilles
Comment 11 caulier.gilles 2006-04-11 10:04:47 UTC
Vardhman, 

Another point is the libgphoto2 version that you use. I suspect a memory leak problem on my computer about libgphoto2 (version 2.1.6-8mdk under Mandriva 2006)

Have you updated libgphoto2 in your computer ?

Gilles
Comment 12 Vardhman 2006-04-11 11:08:04 UTC
No. I only ran a SVN update on kipi-plugins AFAIR. Didn't update anything
else, but the problem of downloading videos disappeared.

Comment 13 caulier.gilles 2006-04-11 11:15:00 UTC
Vardhman,

Like i have said previously, digiKam camera interface do not depand of  kipi/kipi-plugins. Updated something from kipi area do not change anything in camera interface.

But on my computer, i have seen some memory problems relevant of libgphoto2 and others from camera controller implementation. The last one is fixed, but just for information, i would to see witch libgphoto2 release you use on your computer ?

Thanks in advance

Gilles

I am pasting the ouput of the command:

2.1.4 is pretty old. 

Did you by chance update libusb?

If you did, you need to use at least 2.1.6.

yes, me i use this release :

gilles@pc-caulier ~]$ gphoto2 --version
gphoto2 2.1.6

... and i suspect some memory problems with ptp gphoto driver, but i'm not sure...

I  have fixed a memory problem in camera interface. I'm sure about this point. Please, if you use a PTP camera, checkout the new implemention and test camera interface indeep, for example to download a large collection of big pictures.

Thanks in advance

libgphoto2 2.1.6 was caching way too much data, leading to the reported problems...
We have fixed this for the upcoming 2.2 release.

Marcus,

This is want mean that we need to wait 2.2 release before to close this file ?

Currently, i download 1 Gb of RAW files from my Dynax 5D in PTP mode using gdb. I will check if any crash can be reproduce and if memory usage is normal. And i will re-iterate the download at any time to validate.

Vardhman, can you do a similar test in your computer ? Thanks in advance

Vardhman,

I have tested to download over 1Gb of pictures from my Dynax 5D in PTP mode using libgphoto 2.2 (Suse 10.1). All work fine here (reproduce 3x1Gb to download)

I close this file now.
