[Bug 171234] New: Tag names imported from kde3 digikam are cut off in kde 4 version

http://bugs.kde.org/show_bug.cgi?id=171234

           Summary: Tag names imported from kde3 digikam are cut off in kde
                    4 version
           Product: digikam
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           rev: 861503 (using KDE 4.1.1)
OS:                Linux
Installed from:    Unspecified Linux

When upgrading digikam collection from 0.9.x to 0.10, all tag names which are
longer than:

/location/nation/japan/hiroshima/ prefecture/miyajima/mt misen/dai

gets cut off.

I have opened the databases and confirmed that the tag name is cut in
digikam4.db and complete in the digikam3.db. However if I manually edit tags in
digikam 0.10 then I am allowed to store larger tag names (deeper nested tags).

Sound like tags are cuts to 64 char. Sound like tags are imported from IPTC.

Are you imported images as well ? Where is digikam3.db when you import a
repository ?

I have tried with digikam3.db in the same location as digkam4.db is stored as
default and as a custom path later. Images are stored with the same directory
hierarchy in both versions.

I do agree that it does sound like tags are imported from IPTC, but on closer
inspection all I can see in digikams IPTC tab is the following:

Keywords : location, sport, location/nation/japan/hiroshima prefecture,
location/nation/japan/hiroshima prefecture/miyajima, location/natio...

After numerous reinstallation and attempts to imports old tag data, I suddenly
have complete tag names. I have not done anything different. Only removed and
reinstalled digikam, same build from same revision.

You were correct it did only load the IPTC data as I now have both the cut tags
and the complete ones from digikam3.db. Maybe there should be an option to
chose from where digikam should read tag data: IPTC, the old database or both?

I will reinstall and reimport a couple of more times to see if I can find out
what happened and what changed.

The database must be the first way to take tags, because there is no limitation
(size and char encoding). IPTC is a mess, but at least it work a bit.

With digiKam 0.10.0, we support XMP everywhere. There is no limitation to store
tags in XMP. this problem will disapear.

It just a transitional problem in fact between KDE3 and KDE4 version

In Sindre's first attempt, obviously the digikam3.db file was not found and not
upgraded for whatever reason I cannot find out.

The second attempt highlights a problem with reading tags for which there is no
satisfactory solution: When a file is fully rescanned (all files will after
database upgrade, or when manually requested), tags will be rescanned as well.
When there are cut IPTC tags, they will be created as new.

Note that when a file modification is detected, there is no full rescan of
metadata, to avoid situations like this, cut tags popping up again.

In both situations, there cannot be a perfect solution, because one user will
explicitly want his tags scanned, while the other certainly wants to avoid
that. So we do it once at import.

I would suggest to close the bug report unless we can establish a condition
where the old database is reproducibly not found.
Sindre, any more updates, or does it work for you now?
