[Bug 202094] New: Make use of symlinks

Michal Thoma
https://bugs.kde.org/show_bug.cgi?id=202094

           Summary: Make use of symlinks
           Product: digikam
           Version: 0.10.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0 (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

Sometimes I do use symlinks in my workflow. For example I copy images from
archive folders to export folders as symlinks (I use Krusader for that).

The digikam will display symlink, this is ok. Though it will not indicate that
this not not the original image but symlink. I think this should be indicated.

Another problem is that when I edit matadata of the symlinked image, the
symlink actually converts into the original file and original file on archive
location turns invalid (0 byte).

I think ability of creating symlinks is very beneficial for any DAM software.
It enables to sort same data in more then one physical structure. Copying
symlinks to export folder is typical example.

Equivalent and more general feature already avaialble via KDE 4.4.5 drag and
drop to dolpin:
1) Select pictures in digikam
2) Drag and drop into dolphin file manager window while holding Ctrl+Shift

Leaving bug status change to original reporter or assignee.

I'm not sure if I understand. You suggest to use hardlinks instead of symlinks,
is it?

I actually avoid using of hardlinks in my archive. The problem here is
especially with backing-up. On original file system where you created hardlink,
it's ok - it's two files entries and one data. Thought once you copy or rsync
your archive to backup storage - it will create two separate files and twice
more data. And that you definitely don't want. Hardlinks are great thing for
example in creating incremental/differential backups, though for the purpose of
archive structuring I believe symlink is better suited.

Drag and drop into dolphin file manager window while holding Ctrl+Shift creates
symbolic links. This could be an external solution to your digikam feature
request.

It seems we both know and use the differences between copying, symbolic and
hard links.

Ok, I understand. Actually as I indicated in the original report I can create
symlinks using Digikam and Krusader (file manager of my choice).

The serious problem is in the paragraph no 2 and 3 of original post - it's
inability of digikam to recognize, indicate and handle symlinks correctly. I
believe this is still problem with current version so this issue is still
valid.

rsync and many other backup utilities can handle hardlinks properly.  You just
have to pass it the -H or --hard-links switch to tell it to look for and
preserve hardlinks on both sides.

I think, this bug report contains two different symlink "feature
requests"/"bugs":
1. The original report describes the problem, that a user can't see, if an
image is related to a  "real" file or just a symbolic link. (I agree, it would
be very nice to see the difference and, optionally, to hide each one of those
kinds - means: Sometimes I like to see the real ones, only, sometimes the
symlinks, and in some cases I need both)
2. The first comment by Johannes Nieß describes a feature which was IMHO
available in earlier versions of digiKam isn't available anymore in 2.8.0 which
I'm using in Ubuntu 12.10 right now. The availability to easily create symlinks
to a list of selected images by ctrl-shift-drag to an external folder (or even
an internal album) is extremely useful: It connects the "outside world" to the
digiKam DB without just copying the images files to another location. I used it
to create a selection for ordering prints or to burn those images on a CD. With
a folder of symlinked images I can use any tool I like to do what I want, not
just KIPI-plugins, and a symlink need just a few bytes in the FS instead of the
MBs of an image file.
(Even Windows NTFS, BTW, supports soft links, too, so the feature might also be
interesting for Windows-Users)

Since these are two different features, I would request to split this report
into two.

Sorry, typo: I wanted to "suggest" the split.
