Description mathesis 2009-01-18 19:18:37 UTC

Version:            (using Devel)
Installed from:    Compiled sources

How to reproduce:
- Under the same folder, create these 3 files: a_a, aa and a_b;
- Sort by name the files in your folder (with Dolphin).
Result: the sorting is a_a then aa and finally a_b.

Normal behaviour: a_a then a_b and finally aa (in case "_" is considered as being before the letter "a") or  aa then a_a and finally a_b (in case "_" is considered as being after the letter "z").

I don't know what is the order of precedence between letter a-z/A-Z and other (special) characters and if this is also applicable to others characters.

Comment 1 Peter Penz 2009-01-18 23:15:17 UTC

Thanks for the report, but I cannot reproduce this issue: Dolphin sorts it correctly this way:

aa
a_a
a_b

Did you check whether you've activated 'Sort by Name'?

Comment 2 mathesis 2009-01-18 23:36:49 UTC

Very strange, doing what I described I have the same result than you.

Nevertheless, I have an MP3 folder with (so I still have this bug):
queen__radio_ga_ga.mp3
queens_of_the_stone_age__no_one_knows.mp3
queen__somebody_to_love_live.mp3
(in this order and with 'Sort by Name' - I clicked on the name column to do so).

Comment 3 Peter Penz 2009-01-19 10:04:07 UTC

Hm, very strange: Yes, with queen... a wrong ordering is done. I'll have a look on this :-)

SVN commit 965099 by ppenz:

Added test cases for bug 191865 and 181211. The tests pass -> the root cause of the issue seems to be in the used proxy model. I'll check this during the next week...

Comment 6 Peter Penz 2009-05-08 11:31:28 UTC

Update: This seems to be a glibc issue :-( See discussion at http://lists.kde.org/?l=kde-devel&m=124174284926086&w=2 for details...

Comment 7 mathesis 2009-12-28 17:35:19 UTC

Hi Peter,

Any news about this issue?
I understand that KDE team cannot do so much because it is related to glibc, so who can?

Comment 8 Peter Penz 2010-01-05 10:59:34 UTC

For KDE SC 4.5 I try to do mainly polishing in Dolphin/kdelibs and this is one top prio issue I'll try to bypass in kdelibs. Also a little bit related beside the sorting is the wrapping of filenames, that contain '_' characters... In KDE 3 the _ have been handled like spaces or dots for wrapping, in KDE 4 they are handled like letters which often leads to a bad wrapping of filenames. I'd also like to fix the wrapping.
