Description Axel Thimm 2010-07-06 14:39:49 UTC
Version:           1.2.0 (using KDE 4.4.4) 
OS:                Linux

When a Canon PowerShot G5 with a few pictures (20-30) - most of them in raw format - is inserted the initial listing takes very long, in the order of 5-10 minutes. If the link hasn't timed out the thumbnails are downloaded properly. For a successful import I reduced the number of pictures to 15:

Opening the camera in another application (gthumb, shotwell, f-spot) takes only 10-15 seconds for displaying the thumbnails.


Reproducible: Always

Steps to Reproduce:
1. Connect camera to usb port
2. Pick digikam for importing the contents


Actual Results:  
See above. The listing/thumbnail download is painfully slow to the point that the link will disconnect.
Comment 1 caulier.gilles 2010-07-06 14:57:49 UTC
Can you try with digiKam 1.3.0 ?

Gilles Caulier
Comment 2 Axel Thimm 2010-07-06 17:35:51 UTC
I tried building 1.3.0 on F13 (kde 4.4.4), but it looks like digikam 1.3.0 needs libkdcraw >= 1.1.0 and libkexiv2 >= 1.1.0 while kdegraphics-4.4.4 only provides 1.0.0 and 0.6.0 respectively.
Comment 3 Axel Thimm 2010-07-07 08:09:38 UTC
I upgraded to 1.3.0. For this I built and installed the following packages
digikam-1.3.0-1.fc13.x86_64.rpm
digikam-libs-1.3.0-1.fc13.x86_64.rpm
kdegraphics-4.4.90-2.fc13.x86_64.rpm
kdegraphics-libs-4.4.90-2.fc13.x86_64.rpm
kdelibs-4.4.90-1.fc13.x86_64.rpm
kdelibs-common-4.4.90-1.fc13.x86_64.rpm
kio_msits-4.4.90-2.fc13.x86_64.rpm
soprano-2.4.63-3.fc13.x86_64.rpm
(I actually built more, but these were needed for runtime)

The behaviour didn't change the long time execution, the same set of pictures in the same camera now create the following log:

Time mangling is there :

08:51:59 :: Listing files in /home/thimm/.gvfs/gphoto2 mount on
usb%3A005,018/DCIM/148CANON...
08:56:38 :: The files in /home/thimm/.gvfs/gphoto2 mount on
usb%3A005,018/DCIM/148CANON have been listed.

Your camera is canon mounted through Gphoto2 driver. It's not a USB Mass Storage camera. ALso, look like thumb operation are long : 

09:00:19 :: Getting thumbnails for CRW_4900.CRW...
09:00:47 :: Getting thumbnails for CRW_4899.CRW...
09:01:14 :: Getting thumbnails for CRW_4898.CRW...

Around 20 seconds to get one thumb from RAW... 

Here with my Sony camera, UMS mode, getting thumb take less than 1 seconds by item.

Which libgphoto2 version you use ? Look in Help/Components Info for details.

Also take CF card reader, and try please confirm that it's very fast in this case.

Note : Previous week end, i played with a Canon EOS 500D camera from a friend. Camera have been connected to my laptop, running Mandriva 2010.1 (libgphoto2 2.4.9), and all items have been displayed very quickly (all files have been JPEG, not RAW)

Comment 5 Axel Thimm 2010-07-07 09:55:34 UTC
I'm using libgphoto2 2.4.8.

But note that the same library is being used by the other three apps I mentioned and these do pull in the listing and thumbs within a few seconds.

Maybe the difference is in the way libgphoto2 API is used?
Comment 6 caulier.gilles 2010-07-07 10:04:52 UTC
Perhaps.

If you want to take a look, all libghoto2 code called by digiKam is wrapped into this class :

http://lxr.kde.org/source/extragear/graphics/digikam/utilities/cameragui/gpcamera.h
http://lxr.kde.org/source/extragear/graphics/digikam/utilities/cameragui/gpcamera.cpp

GPCamera class is children class of DKcamera :

http://lxr.kde.org/source/extragear/graphics/digikam/utilities/cameragui/dkcamera.h

Gilles Caulier
Comment 7 caulier.gilles 2010-07-07 10:07:11 UTC
A tools to try with digiKam is cachegrind, to look where time is consumed into GPCamera class :

Comment 8 caulier.gilles 2011-08-04 14:37:39 UTC
Same problem than https://bugs.kde.org/show_bug.cgi?id=236394

It's probably fixed in next 2.1.0 (current code from git master)

Can you test with this source code ?

Gilles Caulier
Comment 9 caulier.gilles 2011-08-09 09:25:58 UTC
For me this file is fixed now (future digiKam 2.1.0). Please re-open if
necessary...
