[Bug 150063] New: Rotating JPEG produces error and truncates original file

Summary: Rotating JPEG produces error and truncates original file
Product: digikam
Version: unspecified
Platform: unspecified
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
AssignedTo: digikam-devel kde org
ReportedBy: pwaldo waldoware com

Version: 0.9.2-final (using KDE 3.5.6, Kubuntu (feisty) 4:3.5.6-0ubuntu14.1)
Compiler: Target: x86_64-linux-gnu
OS: Linux (x86_64) release 2.6.20-16-generic

I downloaded a JPEG image (in portrait format) from my Canon Digital Rebel. The thumbnail was rotated properly in Digikam. I copied the source image to another location to do some work on it. The copied image was not rotated; it appeared in landscape mode rotated 90 degrees. I went back to digikam, right clicked the image and selected Rotate|Left. I got an error dialog stating
"Rotating image XXX.jpg.
Failed to Rotate image.
Cannot update source image".

Note that files are stored on a CIFS share, but digikam database is stored locally with a symlink.

There are two issues here:
- For some reason the image could not be rotated.
- More importantly, the original image is allowed to be corrupted!

Paul,

You use JPEGLossLess kipi-plugin to perform rotation. Which version of kipi-plugins you use (warning : kipi-plugins != libkipi)

Also, give us the error messages in the console.

Note : the rotation is performed in a temp file (generally somewhere in /tmp - it's drived by KDE API) and later copied to destination folder to overwrite original file.

I have never tested to use kipi-plugins on a CIFS file system.
