Description Rico 2013-11-06 19:59:43 UTC
I am importing images from a camera (Canon EOS 5D Mk II) that is connected to the computer directly via USB.
I use both automatic file renaming and automatic album creation based on file dates.

File renaming works perfectly. Using this pattern: [date:"yyyy_MM_dd"]_Abc_###[e]
I get exactly the result I expect, e.g. 2013_10_03_Abc_001.jpg

But there is a small problem with album generation.
When I try to generate albums based on date with this pattern: yyyy_MM_dd_'Abc'
I can see exactly what I expect in the preview: 1968_12_26_Abc
But the generated album / folder name is in fact: 2013_10_03_abc

I can't see a reason why the uppercase letters are converted to lowercase.

Reproducible: Always

Steps to Reproduce:
1. Open camera import in digikam
2. Select automatic generation of albums based on file dates
3. Use a pattern that contains uppercase letters like yyyy_MM_dd_'Abc'
4. Import some images
Actual Results:  
Name of created album: 2013_10_03_abc


Expected Results:  
Name of created album: 2013_10_03_Abc

The directory name is lowercased in digikam/utilities/importui/main/importui.cpp's createDateBasedSubAlbum() and there's this comment there:
// See B.K.O #136927 : we need to support file system which do not
// handle upper case properly.

Should there be a check for target filesystem's case-sensitivity support?
Comment 2 caulier.gilles 2013-12-02 15:46:05 UTC
yes, but how to do it ? bu Qt or KDE API ? investigation are required here...

I think there's no need nowadays for undercasing the paths

From my quick tests on Arch with a test file, the original problems sounds like a mounting problem of the distribution or that things have changed since then. You can try the following:

Teemu,

Uncomment this line :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/utilities/importui/main/importui.cpp#L2191

And check :

1/ if capitalization problem disappear
2/ if there is no regression with bug #136927
