[digikam] [Bug 361339] New: Album auto-creation creates nameless subalbums and corrupts album hierarchy

[bugzilla_noreply]

https://bugs.kde.org/show_bug.cgi?id=361339

            Bug ID: 361339
           Summary: Album auto-creation creates nameless subalbums and
                    corrupts album hierarchy
           Product: digikam
           Version: 5.0.0
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: Import
          Assignee: [hidden email]
          Reporter: [hidden email]

I'm running 5.0.0beta5 (digikam-git r33955.9e7223e-1 from AUR) on Arch with a
MySQL backend.

Besides the wanted, correct date-based albums, importing new pictures with
"Auto-creation of albums" creates additional, nameless sub albums which seem to
contain duplicate pictures.

These "ghost albums" seem to have the same effective filesystem path as the
correct ones, so deleting them deletes the wanted subalbums and pictures as
well.

Opening such an album in filemanger reveals empty trailing path components,
e.g.: "/mnt/nas/sandl/bilder/Fotos/Maxi-Test/2016///".

My albums reside on NFS, but the problem exists for local collections as well.
It is also independent of the camera used and of the actual date format (can
also be reproduced with the default ISO format).

As a workaround: How can I get rid of subalbums in the folder pane without
deleting the pictures as well? (Sorry if that's FAQ, I'm quite new to Digikam).

Reproducible: Always

Steps to Reproduce:
1. Create a collection from some existing folder hierarchy (see screenshot 1)
2. Import some new picture which will autocreate new date based subalbums (see
screenshot 2)


Actual Results:  
Additional, nameless subalbums will be created (see screenshot 3)

Expected Results:  
Only the wanted, date based subalbums should be created.

I can not reproduce this problem here (tested with SQLite and internal MySQL
DB). I see no problem in this source code. The same problem, If you manually
create a album (right-click album tree -> New...)? Can you test it with
completely locally album and a SQLite DB?

Thanks Maik, with your help I was able to find a much simpler testcase.

I can reproduce this with SQLite and a local album and even if I just manually
create a new album with right-click, so this is not really an import issue.

However, this seems to require a particular folder structure. To reproduce:

1. Create a file system folder named "Test-local3". Inside "Test-local3" create
an empty folder named "Folder". Inside "Folder" create a folder named
"Subfolder" and put an image there.

2. Create a new Digikam album for "Test-local3" with "Settings / Digikam
einrichten (configure?) / Collections / Add [local] Collection"

3. Right-click on "Folder" and create a new album "NewSubfolder".

4. See a nameless album and duplicate albums appear...

Also with this test case is not to reproduce the problem here. There must be
another cause. In principle, it is impossible that digiKam folder with slashes
created at the end.
Could you try a patch? I would insert more debug messages.

Please try this patch, create a wrong album folder and upload the console
output.

In the "core" folder:
patch -p0 < testDebug.patch

Thanks. Here is the requested log of a small testcase (new album via right
click), reproduced on a different (but very similar) machine.

This is not a productive patch, it is only a test. Please look whether the
issue is resolved.

I'm setting up a new family picture server via NFS V3, server is BTRFS. This
used to work approx. 4 weeks ago, don't know which update broke it.

Latests tests were done on a laptop on ext4 (DB and picture folders). Can also
reproduce on XFS and on Samba mounts, so I don't think it's FS related.

Latest output:
