Bug ID: 372093
Summary: corrupts image file when crashing
Product: digikam
Version: unspecified
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: Metadata
Assignee: digikam-de...@kde.org
Reporter: ka...@posteo.eu
Target Milestone: ---
After having seen a few mid-work crashes, some image files are corrupted in the
sense that they load, but only contain the upper part of the image. It seems
the write to the image file stopped mid-file, presumably caused by a program
crash.
In most of the crash situations digikam was in the process of changing metadata
to a bunch of images. My guess is that it was not only changing this metadata
in its database, but also inside the image files itself. When the process
crashes while rewriting an image file, this file doesn't seem to be protected
against corruption. (I. e. it seems the file gets overwritten directly instead
of writing a copy and replacing the former file only when he new copy was
written correctly.)
[NB: It would take me weeks to find my way through the source code. If someone
might point me to the src file taking care of overwriting image file in the
relevant cases, I _might_ be able to submit a code proposal.]
