[Bug 180351] New: Tooltip exposure shown as "unavailable" even if info present in EXIF

http://bugs.kde.org/show_bug.cgi?id=180351

           Summary: Tooltip exposure shown as "unavailable" even if info
                    present in EXIF
           Product: digikam
           Version: 0.10.0-beta6
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0-beta6 (using 4.1.3 (KDE 4.1.3) "release 4.9",
openSUSE 11.1)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.27.7-9-default

When I hoover over a thumbnail in album view, the tooltip shows the exposure
(and aperture) as "unavailable" even though the EXIF sidebar has both
information. You can find an example file here:
http://www.jbib.de/tmp/pict2826.jpg. This is a JPG file created with a Konica
Minolta 7D straight from camera. Other meta-data are shown correctly (eg
dimensions, ISO, focal length).

I confirm this bug.

I just copied this file in my collection when digiKam running.

The file appear in icon view, but all photograph information are not imported
to the database automatically.

Marcel,

re-starting digiKam do not help.

Going to Caption & Tags and using More/Read Metadata from File to Database do
not help

Marcel,

I found a way to see photograph information with this image.

1/ stop digiKam
2/ copy file to collection
3/ start digiKam
4/ if scan for new image at startup is not set on, start it manually from Tools
menu
5/ The image is now on icon view with all photograph info.

No problem for me here, everything from the metadata is shown. No difference if
imported with digikam running or not (of course, I removed the database entries
before). Can you reliably reproduce this?

Marcel,

Are you changed something in code ?

Why it doesn't work here ? It's relevant of digikam4.db file ? I need to remove
it before to test again ?

No I'm not aware of any relevant changes - it just works here...
(I updated exiv2 yesterday because of the other bug, that's the only change I
see here)

To re-import from scratch, remove the whole digikam4.db, or just remove all
entries for this file:
DELETE FROM Images WHERE name ='pict2826.jpg';
(Hope you have no other image with the same name;-) )
and restart digikam, or remove the file and add it while digikam is running.

If you can reproduce, it would be interesting to get a database dump:
SELECT * FROM Images LEFT JOIN ImageMetadata ON imageid=id WHERE name
='pict2826.jpg';

Marcel, trying to import again this image in my collection when digiKam already
running doesn't work. No photo info avaialble.

Are you see that Color Mode of this image is YCbCr not RGB. Perhaps it's the
problem?

See below the database dump:


[gilles@localhost photo]$ sqlite3 digikam4.db
SQLite version 3.6.1
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> SELECT * FROM Images LEFT JOIN ImageMetadata ON imageid=id WHERE name
='pict2826.jpg';

Marcel,

Renaming digikam4.db to digikam4.db.old solve the problem.

Runing digiKam and importing the file again in collection work fine now.

I will attach bziped DB file for investiguations...

Please rename your digiKam database file as explained before in this thread and
try again.

I cannot find out why this image was imported without metadata information into
the database at first, if new attempts with a fresh database do not reproduce
this.
I see some related TODOs. The collection scanner perhaps relies a bit too
strongly on information it has already in its database. We also need to clear
up the actions "Refresh", "Synchronize Images with database", "Update Metadata
database", "More->Read metadat from file to database", "More->Write metadata to
each file", sometimes do not do what they say (or they are unprecise in saying
what they do), or it is not really clear which images are affected. But I would
prefer to do that when the batch manager is implemented.
