[Bug 199981] New: XMP synchronization of digiKam namespace occurs for second tag

[Tim Jenness]

https://bugs.kde.org/show_bug.cgi?id=199981

           Summary: XMP synchronization of digiKam namespace occurs for
                    second tag
           Product: digikam
           Version: 1.0.0-beta2
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.0.0-beta2 (using KDE 4.2.4)
OS:                Linux
Installed from:    Gentoo Packages

I have enabled the synchronization of metadata to files. In version 1.0.0-beta2
if I add a tag to a file the XMP metadata tab is updated in digikam to reflect
that an XMP section has been written but the digiKam section is not present.
The file includes the following XMP information:

Xmp.tiff.Software                            XmpText    19  digiKam-1.0.0-beta2
Xmp.tiff.DateTime                            XmpText    19  2007-05-13T14:52:58
Xmp.xmp.CreatorTool                          XmpText    19  digiKam-1.0.0-beta2
Xmp.xmp.CreateDate                           XmpText    19  2007-05-13T14:52:58
Xmp.xmp.MetadataDate                         XmpText    19  2007-05-13T14:52:58
Xmp.xmp.ModifyDate                           XmpText    19  2007-05-13T14:52:58
Xmp.exif.DateTimeOriginal                    XmpText    19  2007:05:13 14:52:58
Xmp.photoshop.DateCreated                    XmpText    19  2007-05-13T14:52:58

Adding a second tag leads to the digiKam section appearing in the XMP metadata
tab and in the file (and the lr. namespace appears in the file). In my testing
the other day I got the impression that adding an additional tag would not
appear until the tag after was added but I can not reproduce this now. It just
seems that digiKam tags are not synched until there are at least two so it
looks like an off by one error in the code somewhere.

Code is there :

http://lxr.kde.org/source/extragear/graphics/digikam/libs/dmetadata/dmetadata.cpp#578

and this method is called from there :

Thanks. I'll try to rebuild digikam with some debugging to see whether it
enters that routine the first time. Do you see the behaviour that I see or does
it all seem to work for you?

Works for me as well. It's only when I start with an untagged photo without any
XMP or IPTC information and then tag it that I get the partial write of XMP
information. When the second tag is added the first tag is also written to the
file and then I can add and delete whatever I want. Will try the test again
tonight.

Rebuilt the whole thing and now it does work and writes the tag instantly.
Sorry for the noise. I wonder if it was caused by the program originally being
built against an exiv2 0.18 that did not have XMP enabled...
