[Bug 220204] New: digiKam could warn when writing metadata to pictures fails

[Vlado Plaga]

https://bugs.kde.org/show_bug.cgi?id=220204

           Summary: digiKam could warn when writing metadata to pictures
                    fails
           Product: digikam
           Version: 1.0.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.0.0 (using KDE 4.3.2)
OS:                Linux
Installed from:    Ubuntu Packages

When the user wants digiKam to save picture meta data in the picture files it
could warn the user if writing to a picture file fails. One reason for failure
could be a read-only file.

Of course there should only be one warning per user interaction, not hundreds
(at least if the warning comes in a "click ok dialogue"), even if hundreds of
files should be changed at once.

Can you take a look with digiKam 1.2.0 ?

The bug is still valid in digiKam 1.2.0.

To reproduce: take two pictures, make one of the read-only ("chmod -w"). Then
in digiKam change their rating, comment, whatever. Notice how only the writable
file is really modified (if your setting is to save metadata in pictures at
all), without digiKam giving you a warning. Changes to the read-only file are
only saved in digiKam's database.

Yes, digiKam 2.1.1 still does not say anything when "Metadata Writing Mode" is
set to "Write to image only" and writing to the image is not possible, because
it is write protected.

There now is the new option "Write to XMP sidecar for read-only image only" and
that seems to work as expected: in my test an XMP sidecar file was only created
for the image that was not writable, when I tried to change metadata for two
images.

By the way: I got some strange output on the console during these tests:

digikam(18574)/digikam (core) Digikam::CollectionScanner::scanAlbum: Folder
does not exist or is not readable:
"/daten/digicam/nijmegen/2011-10-08__12-25-40.jpg18574"
digikam(18574)/digikam (core) Digikam::CollectionScanner::scanAlbum: Folder
does not exist or is not readable:
"/daten/digicam/nijmegen/2011-10-08__12-25-40.jpg"

There were more path names ending in "18574" mentioned for other images.

We still dont have that implemented. Would need some sort of unobtrusive
warning.

I would say digikam *should* warn user
Anyway, an easier way to *reduce* the problem is providing a log file of
metadata writing and log all failure with files and attempted changes.
