Created attachment 126930 [details] destroyed TIFF images (within .zip file) SUMMARY star rating on TIFF images randomly destroys the images. I did the star rating to aprox >200 images. After this 8 images were destroyed - they are almost black with some stripes. I tried the same on .jpg images but it seems to me that this is specific to TIFF format. STEPS TO REPRODUCE 1. have a view on many images (TIFF format) (e.g in preview). 2. do star rating on many images - do it fast so that processing is queued 3. wait until all ratings are processed 4. update the view (F5) this will reload thumbnails and shows the destroyed images - if there are any. It seems to me that there is a problem with multithreading? I have attached one destroyed image (zipped) OBSERVED RESULT several images are destroyed --> image can be loaded but is almost black EXPECTED RESULT images should remain unchanged - except the star rating SOFTWARE/OS VERSIONS Windows: 10 pro 1909 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION digikam version 7.0.0 - beta2
In the image, very large areas are filled block by block with zero bytes. Can you rule out a hard disk error? Please download "DebugView" from Microsoft and start it. Try to reproduce the problem in digiKam and upload the log from DebugView. Maik
Hi Maik, wow that's fast reply - thanks!! The images are on a network storage - I did some tests moving them to another (diret conected) disk - and could not reproduce the problem!! I will continue to find the root cause, but for now you can reject my defect. I'm sorry, this simple test I could have done in advance - Thanks a lot!

Hi, Can you check if this problem still exist with last weekly bundle build of digiKam 7.0.0 available here: https://files.kde.org/digikam/ Thanks in advance Gilles Caulier
digiKam 7.0.0 stable release is now published: https://www.digikam.org/news/2020-07-19-7.0.0_release_announcement/ We need a fresh feedback on this file using this version. Thanks in advance Gilles Caulier
Dear Gilles, sorry for delay in my answer - I was on holiday... I did a short test now and I have found no problem. But let me do some more testing, because this error appears randomly and seldom. I will replay again latest tomorrow evening. Are there changes done regarding this bug? Are this related to TIFF files? regards Dirk Am 30.07.2020 um 11:45 schrieb bugzilla_noreply@kde.org: > https://bugs.kde.org/show_bug.cgi?id=419079 > > --- Comment #4 from caulier.gilles@gmail.com --- > digiKam 7.0.0 stable release is now published: > > https://www.digikam.org/news/2020-07-19-7.0.0_release_announcement/ > > We need a fresh feedback on this file using this version. > > Thanks in advance > > Gilles Caulier >
Hi, applying start rating will embed information in tiff tags metadata using Exiv2. As we update last stable version of Exiv2 in Windows installer, the problem can be fixed indirectly. I'm waiting your feedback tomorrow evening. Gilles Caulier
Dear Gilles, I tested with several hundred changes of ratings on TIFF (and also DNG) files without any problem. Seems to me that the problem is solved :) regards Dirk Am 30.07.2020 um 22:50 schrieb bugzilla_noreply@kde.org: > https://bugs.kde.org/show_bug.cgi?id=419079 > > caulier.gilles@gmail.com changed: > > What |Removed |Added > ---------------------------------------------------------------------------- > CC| |caulier.gilles@gmail.com > > --- Comment #6 from caulier.gilles@gmail.com --- > Hi, > > applying start rating will embed information in tiff tags metadata using Exiv2. > As we update last stable version of Exiv2 in Windows installer, the problem can > be fixed indirectly. > > I'm waiting your feedback tomorrow evening. > > Gilles Caulier >
