Bug 141601

The file size is cached in the image info object. Not only the album view is affected, but also the right side bar in album view and in the image editor, for all cached fields (date!, not tags, rating).
This requires some deeper changes in the way we currently use the ImageInfo objects.

This behavior is very problematic when changing the date of the picture using the right-hand side Comments/Tags tab.

The thumbnail view does not reflect the new date, so I first I thought the dates were not updated properly.

Additionally, when using the left-hand side Dates tab, changing the date of a picture should then put it into the correct category of the tab. For example, when I am viewing pictures of December 2006 and change the date of a picture to 26. November 2006, it should disappear from the thumbnail view (because we only want to see December 2006 pictures). It should only reappear when selecting November 2005 in the Dates tab.

Not seeing the effects of my date changes makes the date change feature unusable for me (and sadly I need to use that often because I had a broken camera regarding dates).

Actually, I can no longer reproduce this, it now seems to work as it should. Strange...

Anyway, then only the problem that remains now is that the date shown in the thumbnail view is not immediately updated, only after switching albums.

It happend again. Seems like the pictures sometimes correctly rearrange themselves to the correct date folder, and sometimes don't. Note that this also does not work with search folders which have dates in their criteria, but again only sometimes.

Another thing which is not correctly updated is the file name after using the batch rename tool.

Additionally, the thumbnail, file size and everything else should be updated after editing a picture with showfoto.
I want to see the new thumbnail after improving my picture with the editor.

Daniel,

It still valid using digiKam 0.9.4 ?

Gilles Caulier

Still exists in 0.9.5svn - although not always reproducible.

Interesting thing: when removing comment size of image isn't always decreasing and when decreasing it doesn't decrease by size of comment. During tests for this bug report with few similar comments (each 10-15 chars) image of size increased about one hundred bytes. Not bug per se but strange.

And in 0.10-beta7 I am completely unable to update file size. OK(?) - restart of digiKam did it.

SVN commit 896523 by mwiesweg:

When writing metadata, directly scan the file for db changes.
The dir watch does not always get subtle file changes that only
involve writing to an existing file.

Miko, for KDE4:
- we cannot always catch a file change if it is done from outside (with exiv2, exiftool in this case), see my last comment for bug 151552
- I have fixed some problems when changes are done from inside digikam.
  Please let me know if you still have situations where an action from digikam modifies the file size, but it is not updated in the icon view / right side bar

Size is updated. Original report is FIXED. There were additions in discussion - so I am leaving closing of this bug to the discretion of developers.

Marcel, 

We can close this file for 0.10.0-beta7 ?

Gilles 

For me it's fine to close as fixed for KDE4.

Ok. Fine. Another one for beta7...
