[Bug 301482] New: xmp sidecar files not being generated for .3xf raw file type

[Danni Coy]

https://bugs.kde.org/show_bug.cgi?id=301482

            Bug ID: 301482
          Severity: normal
           Version: 2.6.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: xmp sidecar files not being generated for .3xf raw
                    file type
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Compiled Sources
            Status: UNCONFIRMED
         Component: Sidecar Management
           Product: digikam

I am seeing sidecar files being generated for every file type in my collection
except the sigma (x3f) raw files for my camera. I have digikam set to write to
both the image and a sidecar file and I have writing to metadata to raw files
enabled (for some of the other types of raw files in my collection).

Reproducible: Always

Steps to Reproduce:
1. add tag to a x3f raw file in Digikam.
2. (optional) use image -> write metadata to selected images
3. check folder in dolphin for sidecar file.
Actual Results:  
sidecar file should appear in the same folder as the image

Expected Results:  
sidecar file was never created

Which digiKam metadata settings you use ? Look into Setup/Metadata dialog for
details...

XMP side car files are managed properly with other image mime type, as NEF,
CR2, PNG, JPG ?

jpeg,tif,png, CR2 (cannon raw)  RAF (fuji raw)- yes sidecar files are being
generated
gimp xcf (no sidecar file).
x3f (sigma raw) no sidecar file.

all options for generating metadata are ticked
read data from sidecar files is checked
write data to sidecar files is checked and set to "write to image and sidecar
file"
write data to raw files (experimental) is checked.
update timestamp is not checked

There is no reason technically than no sidecar is not generated for specific
file as XCF or X3F. Can you take a screen-shots of your setup metadata config
panel ?

Also, i would to know which version of Exiv2 and libkexiv2 you use. Go to
Help/Components Info for details.

And finally, please run kdebugdialog and turn on KExiv2 debug space. Now, run
digiKam into a console and reproduce the problem. Please post the console trace
here...

Created attachment 71698
  --> https://bugs.kde.org/attachment.cgi?id=71698&action=edit
screenshot of metadata settings for digikam

could it be possible that digikam is trying to write to the raw file and when
that fails it is forgetting to write the sidecar file?

Yes i suspect this dysfunction on your computer. In fact this part is manage in
Exiv2 KDE interface written by digiKam team : libkexiv2. It's important to know
libkexiv2 version used by digiKam (Help/Components Info), because if i'm not
too wrong, it have been fixed something like this in libkexiv2 few month ago.
Perhaps libkexiv2 form kdegraphics/libs, released with KDE, is a little bit too
old...

libkexiv is at 2.1.0
exiv2 is at 0.22 (looking at package version in Kubuntu)

The debug output from kexiv2 is definately showing a problem...

The current implementation separate well the way to write into file :

https://projects.kde.org/projects/kde/kdegraphics/libs/libkexiv2/repository/revisions/master/entry/libkexiv2/kexiv2.cpp#L428

and the way to write sidecar :

https://projects.kde.org/projects/kde/kdegraphics/libs/libkexiv2/repository/revisions/master/entry/libkexiv2/kexiv2.cpp#L438

If the first fails, the second is done as well...

--- Comment #10 from Gilles Caulier <[hidden email]> ---
Exiv2 version is fine.

libkexiv2 is too old... I think it's fixed with 2.2.x.

Can you try to recompile yourself digiam Software Collection 2.6.0 which
include last libkexiv2 ?

--- Comment #11 from Danni Coy <[hidden email]> ---
ok - i managed to jimmy a newer version of libkexiv2 into my system and can
confirm that I can now write sidecar files for any format. Thanks for your
help, I am off to back up 15,000 raw files.
