Description Andi Clemens 2012-04-06 17:47:27 UTC
When I run the maintenance tool with "scan for new images", "rebuild thumbs (scan)" and "rebuild fingerprints (scan)", the maintenance tool action is disabled. Only restarting digiKam will enable it again.

You don't have fixed the action menu relevant previously in beta2 or 3 ?

It seems not all situations where handled by the fix...
Comment 3 caulier.gilles 2012-04-06 18:08:05 UTC
I see some dysfunctions today about scancontroller ProgressItem, when i imported few items from my camera. Can you reproduce ? Code relevant is here :


I think the way to connect and manage with scancontroller is not fine. in fact, i a little bit lost with scancontroller code...

I could not reproduce it, but maybe I'm doing something wrong / different than you were doing while importing.

Fix for the described tool setting. I will need to re-check other combinations, too.

Do not start a tool immediately in the constructor. This will lead to race conditions.
Also we try to connect signals to tools AFTER they started doing their job. This will not work for tasks that close immediately, e.g. "Scan for new items" on a very small collection. In this case the signal becomes connected AFTER the tool is done, therefore never executing the assigned slot. There are still some race conditions left, I need to check them, but for now the main issue in this bug report should be solved.

Maintenance Manager : complete rewrite of maintenance tools handling.
Instead to use signal provided by tool to know if job is done, use progress manager signal.
Store instance of each tools in d private container instead stack to provide a better check of stage under progress.
Patch ScanController to provide a better feedback to NewItemsFinder, in all scan mode. Add a new method to only call core code to perform
scan WITHOUT to show a progress dialog. In fact progress manager as already all in place to give user feedback about progress...
Patch FaceManagement maintenance tool to indicate that face are detected and recognized.
Move status progress bar with ProgresManager code, as this one is fully relevant.

Marcel, I would to drop fully DProgressDialog code, which is only used now to ScanController, with all first run step to collect all information from image
managed by database. I remember that in 2.x serie, you have patched digiKam to only perform first run scan in background when albumgui is show. I'm right ?
At now, this feature sound fonctionnal some time, but it's not fully reproducible.
If you take a look how Google Picasa work, you will see that main DB referencing run in background when main GUI is displayed. A progress indication is show in statusbar.
User can start to work with collected items in real time and don't need to wait a long time that all referencing is done through a small progress dialog...
Look this entry for ex : 320359.
What do you think about?
