Description Jesse TeKrony 2013-09-30 03:41:11 UTC

I have a samba share mounted with autofs. I have set the uid and gid so I have proper access to the directory and I am able to create/delete files. However, when attempting to import pictures, the process ends almost instantly and no pictures are copied, but subdirectories for date-based subalbums are created. I end up with my sambe share full of empty folders.

I am also sure that autofs has actually mounted the directory before I attempt to import the pictures.

I have had success in the past mounting the share using cifs in /etc/fstab, but I find that this slows down the boot process considerable and autofs is a much more slick solution.

(On a side note, is digiKam still unable to trigger the autofs automount at application startup? I don't mind putting an 'ls <share>' in the autostart settings, but it would be nice if I didn't have to. In fact, the website still states that mounted shares don't work at all.)

Reproducible: Always

Steps to Reproduce:
1. Ensure samba share is mounted by autofs and you have read/write access
2. Launch digiKam and create a new album pointing to the share
3. Attempt to import pictures to the share
Actual Results:  
The process instantly completes and no pictures are copied, however directories are created based on subalbum rules.

Expected Results:  
Pictures should have been copied to the share directory.

One more thing that I might add is that digikam doesn't log anything to stdout about this.

digiKam delegate all copy sttuff to network device to KDE kioslave interface. You must hack debug messages from KIOSLave :

"You can start klauncher in such a way that slaves for a certain protocol (the first parameter of KIO::SlaveBase() constructor of the slave class) are started in debug mode."

What protocol does digiKam use?

Comment 4 Jesse TeKrony 2013-09-30 19:45:10 UTC

Using some bash-fu to search the source code gives me some results for "KIO::SlaveBase", but I can't seem to find anything indicating the protocol. (My knowledge of C++ is very basic)

After fiddling around with the debugging settings a bit, I can see errors now:
digikam(24165)/digikam (core) Digikam::UMSCamera::downloadItem: Failed to open dest file for writing:  "/var/shares/pictures/2008_11/.digikam-camera-tmp1-24165Picture1.jpg"

Comment 6 Jesse TeKrony 2013-10-01 03:04:05 UTC

I have also found that mounting using cifs in /etc/fstab doesn't work with digiKam either. I have gotten this to work in the past, but it seems broken now.
