Summary of Bug 119073: wish list rescan option:

>>Occasional digikam fails to show newly downloaded photos in the >>directory listing. The easiest way to get them to show up is to close >>digikam then it will automatically rescan when it is reopened. 
>> Please include a 'rescan' menu item so that the database can be >>updated without having to restart digikam.

Tom,

I have the same problem with my camera in USB mass storage mode and I have found a simple exemple I can always reproduce. I hope you can reproduce it too:

1) Create an empty folder /home/yourusername/camera.

2) Download "Photo 003.jpg" attached to this bugreport and place it in /home/yourusername/camera.

3) Run Digikam 0.8.0 and point it to an empty Album library path.

4) Now, add a "Mounted Camera" with "Camera Mount Path=/home/yourusername/camera" (we simulate here my USB mass storage camera).

5) Download "Photo 003.jpg" with the option "Download photos into automatically created date-based sub-albums of destination album" (choose "My Albums" as destination album).

6) Now, the folder "2005-07-17" containing "Photo 003.jpg" is created in "My Albums" but does not display "Photo 003.jpg" thumbnail.

7) Restarting DigiKam solves the problem.

Okido, confirmed. Looks like new folders created by the camera dialog are not picked up.

proposed patch

Tung, attached a patch for the problem: 
    When a directory is created, a watch is put on it to spot new files
    but it can occur that the file is copied there before the watch is
    completely setup. That is why as an extra safeguard run scanlib
    over the folders we used when the cameragui is closed.

Could you test it for me?
Comment 4 Tung NGUYEN 2005-12-31 13:17:22 UTC
Tom,

I have to read some doc on how to merge a patch... :-)

Promised, I will test it for you as soon as possible.
Comment 5 Tom Albers 2005-12-31 13:32:25 UTC
Tung, if you have our unpacked tarball, go into the digikam folder and apply this patch with: patch -p0 < downloaded file

If it complains it can not find the file, try -p1

If it is ok, it tells you that it is applied succesfully, after that you can do make and make install as usual.
Comment 6 Tung NGUYEN 2006-01-02 19:33:57 UTC
Tom,

I have tested your patch on DigiKam 0.8.0 tarball, it works fine. Thank you. You can close this bug report.
