[digikam] [Bug 338532] New: Sidecar files are neither created nor updated under Windows

[Piter Dias]

https://bugs.kde.org/show_bug.cgi?id=338532

            Bug ID: 338532
           Summary: Sidecar files are neither created nor updated under
                    Windows
           Product: digikam
           Version: 4.2.0
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Sidecar Management
          Assignee: [hidden email]
          Reporter: [hidden email]

Created attachment 88408
  --> https://bugs.kde.org/attachment.cgi?id=88408&action=edit
Windows (left) and Linux (right) settings

Sidecar files are neither created nor updated under Windows x64 8.0. I included
some tags to my photos without any sidecar file to be created, although the
tags are available (saved in the database, perhaps?). The current sidecar files
are not touched either when tags are changed.

Under Ubuntu server x64 13.10 everything is good, sidecars are either updated
or created, depending on they already exist or not.

Both Windows and Linux have the same settings for metadata.

Under Windows can you run :

- run kdebugdialog from KDE and turn on debug space of digiKam, especially
KEXIV2
- install and run deview.exe to see console output from digiKam
- run digiKam and reproduce the dysfunction
- report here the debugview trace from digiKam.

All is explained here in details : https://www.digikam.org/contrib

All code relevant of XMP sidecar creation/update is called in libkexiv2.

As i can see :

KExiv2Iface::KExiv2::save(const class QString &) const: Metadata for file '
"_MG_5590.CR2" ' written to XMP sidecar.

This want mean this code is called :

https://projects.kde.org/projects/kde/kdegraphics/libs/libkexiv2/repository/revisions/master/entry/libkexiv2/kexiv2.cpp#L447

and this call this method :

https://projects.kde.org/projects/kde/kdegraphics/libs/libkexiv2/repository/revisions/master/entry/libkexiv2/kexiv2_p.cpp#L66

Where only code from Exiv2 shared lib is called and wrapped to C++ exception
handler.

So i suspect really an Exiv2 problem here...

Under Windows, which Exiv2 version you use exactly ?

Look into digiKam Help/Components Info dialog for details.

yes, Exiv2 library is an older one, which can be the origin of the problem.

Libkexiv2 interface is the same version, that a good point here.

I CC Exiv2 coordinator to see if he know a Windows bug fixed with version >
0.22

Ananta,

For next version 4.3.0, it will be nice to use last stable Exiv2 library 0.24
with digiKam to prevent the risk of re-introduce unwanted bugs.

Next digiKAm version 4.3.0 is planed in one week.

I will also add more debug statements in libkexiv2 to see if all stage of
metadata saving operations are fine.

Please test digiKam 4.5.0, this should be fixed now due to major fixes with use
of exiv2 on Windows:
