[Bug 171310] New: No preview photos shown clicking on imported albums

http://bugs.kde.org/show_bug.cgi?id=171310

           Summary: No preview photos shown clicking on imported albums
           Product: digikam
           Version: 0.10.0-beta3
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0-beta3 (using 4.1.2 (KDE 4.1.1 (KDE 4.1 >= 20080828))
"release 52.1", KDE:KDE4:Factory:Desktop / openSUSE_11.0)
Compiler:          gcc
OS:                Linux (i686) release 2.6.25.16-0.1-default

In $HOME/Pictures I have a directory tree with photos in different
subdirectories.
Using digikam 0.10.0-beta3, there are no photo previews of existing image files
in albums, if I click on the albums imported from a file tree. On the right
side I see only the "Welcome to digiKam 0.10.0-beta3" page, nothing else in
neither album.
"Refresh" and "Synchronize images with database" does not help.
Futhermore, I deleted my .digikamrc and started from scratch, again using
$HOME/Pictures as root path for albums and the image database, too. No effect.

Redirecting the digikam-0.9.4 for KDE3 to $HOME/Pictures the preview works
fine.

René.

There is a side effect somewhere. To solve this problem, go to tags view and go
back to album view. thumbs appears ?

Look also in the console if some error messages are visible.

At end, try to use current code from svn (beta4) where Marcel has fixed a lots
of code relevent of Digikam::AlbumManager core component.

Hi Gilles,

After starting digikam without doing anything:
---
Found dcraw version: 8.87
File '' is not readable.
---

Switching between the tags view and the album view doesn't have influence on
this. Nothing happens on console during doing so.

On "Tag" -> "New" I get a popup with
Create new tag in "/".
On the console I get another
---
File '' is not readable.
---
but only once, not more times.

Tell me if I can provide you more information.

René

Oh sorry, you are right.
I tried only the "Caption/Tags" on the right side.
Checking the real "Tags" view and returning to the album view the preview is
shown.
Sorry, I'm still not fit with the new Digikam features ;-)

René,

This is a bug of course (:=)))

Marcel,

As you see this dysfunction from AlbumManager ?

I can confirm this, too. Neither a imported folder nor freshly detected image
albums (by scan for new images) do appear in the album view. Of course I'm
using latest trunk.
The same for is true when adding new album collections.
By the way: What is the purpose of giving names to the collections? They will
be renamed anyway. Or am I misunderstanding this.

Just wanted to mention that a restart of digiKam will display those new
albums...

Marcel,

is it really working for you now? I just tried it again in a pure KDE4 desktop
as well as in a KDE3 environment, freshly imported albums and images don't
appear.
I need to restart digiKam to see them.

Andi

Ok, I did fix a bug, but apparently not this one.
I can currently crash digikam by using Import->Add Images, and Image->Add
Folders is not working for me. These are bugs of course.
What works is just copying over a folder from the command line outside digikam.
This works well for me, the album and the contained picture appears when
scanned. Does this work for you?

"Add Images" or "add folders" works fine here, also copying on commandline will
show the images. The only thing that is not working is adding a new collection,
if I do so I need to restart digikam.

Oh just found out that the new images are only visible if I copy or import them
into an existing album, if I create a new one, the folder is visible but empty,
just like if I had created a new collection.

I think I found the cause for the collection problem, a really tricky one, took
a bit longer to find out: When a new collection is added, we start a complete
scan, which uses a transaction; during the transaction, the changes I assume
cannot yet be read from the db file, so the album is not available when the
creation message comes to AlbumManager. I'll think about fixing that.

The other problem you mention in #13: How do you create the folder, from within
digikam with New Album, from outside? How do you put images in there, from
inside or from outside?

I created the album from outside, by commandline this time, need to check if it
behaves the same when creating an album inside of digikam.

Marcel, CCBUG macro is not yet restored...

I CC your commit...

SVN commit 864582 by mwiesweg:

When in a transaction, send out changesets only after completion of the
transaction, as other db connections will not be able to read the changes
so far.
Fixes the Collection-albums-empty problem for me.

SVN commit 864774 by mwiesweg:

Among some minor changes, fix one more stupid mistake:
Exclude the just added image from searching for identical files,
as obviously it will be falsely found otherwise, resulting in empty db entries.
