Selected commits
SVN commit 985202 by mwiesweg:
Remove "optimization" in slotLayoutChanged that only causes relayout if certain tested
filter parameters have changed. But neither testing these parameters nor testing
for rowCount can rule out the necessity of a relayout (our filter models e.g. dont
care about these parameters. Row count may be the same but completely different
indexes may be present).
Remove dataChanged reimplementation. This may cause side effects!
But I see no need for this. And even less for caching visual rect before
a possible relayout. For me, if a proxy model wants to re-categorize,
it should emit layoutChanged().

SVN commit 985047 by aclemens:
Dropping an album into an empty space in the albumfolderview added this
album to the albumroot. But since we have multiple collections, this
isn't working anymore.
Disabling it for now because we get an error, but I would suggest to
remove this forever, because we can not guess the
correct collection, in where the album should be moved.

1 file changed
SVN commit 985277 by aclemens:
Add a new method to get invalid filePaths. This should speed up the
batch thumbnailer a lot if used on a big collection.
Unfortunately it seems that we are not (yet) using the NoThumbnail flag
(or we don't add files without thumbs at all to the filePaths table).
When adding new files, they don't appear in the thumbsDB when the album
has not been opened or the batch thumbnailer has not yet run.
Maybe we should add files immediately to the thumbsDB when they are
added to the collection and set the NoThumbnail flag.

SVN commit 986000 by mwiesweg:
Nepomuk coding sprint results:
Initial revision of a Digikam <-> Nepomuk synchronisation bridge.
For now this is implemented as a Nepomuk service running independently
from the main digikam instance.
Syncs rating, comment and tags; tags is one-way currently, syncing tags
from Nepomuk to digikam is awaiting implementation.
Changes in digikam are immediately pushed to Nepomuk by listening to
digikam's DBus signals. After first start, a full sync of all entries
is triggered. The initial sync is recorded in the database.
Changes in Nepomuk are registered by listening to global change signals.
After a timed delay a Sparql query retrieves all relevant changes
that occurred since the last check. The time is recorded in the database.
The database file path is read from the digikam configuration file.
If an instance is running, it is queried directly. If the database file
changes, the service is informed by digikam. (This does not scale well to several
instances running different DBs, but digikam does not support this scenario anyway)
Both syncing directions are independently configurable. Default is false for now;
we should consider defaulting to true.
Note: I am running KDE4.3beta2 at the moment. If there is code not compiling with
KDE4.2, we must add a conditional switch to CMake.

SVN commit 986001 by mwiesweg:
Add compilation of Nepomuk sync service.
Please test if this is fine with KDE4.2! If not, we must make it optional
for KDE >= 4.3. I guess that should be possible with CMake.

SVN commit 986330 by mwiesweg:
Clear selection before calling setCurrentIndex() at those places where the intention
is clearly to set exactly one selected + current index.
If Ctrl or Shift are pressed, maybe for any unrelated purpose, it would be taken
into account because the selectionCommand() is shared for all purposes including
mouse selection, keyboard selection and programmatical selection.

Add new tests for ImageLoader classes.
They don't do much yet, but it seems we already found a bug in
PNGLoader.
We need definitely more test cases for digiKam ;-) also to reduce
regression errors.

SVN commit 988322 by aclemens:
Removing this code again, it will not make things faster.
I did a lot of I/O performance testing now and at least with our sqlite3
solution, we really have reached the limit, it is just not performing
well on bigger collections.
My thumbsDB is 970MB big, and when the disk cache has not been already
filled, querying the database is painfully slow.
This is not digiKam's fault, it can be easily reproduced in the sqlite3
command line tool.
as root:
sync
echo 1 > /proc/sys/vm/drop_caches
Now your disk cache is cleared, as if the system just started up.
Run a simple query on a bigger thumbsDB like:
select count(*) from thumbnails where type = 0;
Even though this query delivers no results, it takes up to 20 seconds to
completely parse the table.
When used in digiKam, the application is not responding at all during
this operation, you get the impression that digiKam just hung up.
I have a large RAM here (4GB), but I don't know what happens if you run
digiKam 1.0.0 on an average system with 512MB or 1GB RAM.
For me the only solution is to go with embedded MySQL or even a real
MySQL server solution.
Because now we don't have just one, but two rather big databases.

Little performance improvement: Don't call if (QRect.contains()) for
every single point to draw the transparent gray overlay for
the aspect ratio widget. Especially when images are bigger, this is very
slow. It still isn't fluent, but at least a little bit faster.

Then hopefully postgresql would be supported too.

*If* digiKam abandons sqlite in first round it should be something MySQL based to minimize digiKam specific dependencies. MySQL-embedded is used in Amarok, very popular music player, and full MySQL server is backend for Akonadi, core part of KDE.
In future... Who knows? :)

i'm VERY happy for the nepomuk integration!
Exciting stuff in DigiKam
First of all - DigiKam is one of the most important applications to me as photography for me is a way to relax :-)
Congratulations on the progress you are making. I think it looks exciting and I am looking forward to new releases!
The compatibility with Lightroom is especially interesting to me as I am a paying Lightroom owner and would love to be able to move all of it over and keep as much as possible.
One feature from Lightroom that I miss on import of pictures is the possibility to autocreate folders based on a date pattern (of when the picture was taken, not imported) e.g. Pictures/year/month/day is a systems I prefer using.
Regarding MySQL - I would love to be able to put all pictures on the server at home and use DigiKam on everyone PC's to watch the pictures. That would make things a bit easier. Especially if I could mark all my pictures as Read-only so the others could not save any changes to the originals. As we are in the digital age, originals should actually be marked read-only automatically on import.
One big wish from me is to move a little closer to the color correction of Lightroom. I really like the way you work there and the options.
Do you mean in example, that
Do you mean in example, that you have shooted on three days on last week and when you import, the digiKam reads all the metadata and creates albums like 2009_06_31, 2009_06_28 and 2009_06_25 ?
