Description Patryk Benderz 2015-10-28 13:51:05 UTC

Krusader sees space at the beginning of some files/dirs while ftp to AIX FTP servers, which makes it unable to enter these directories. Be aware, that there are in fact NO SPACES at the beginning of folder names when you list them while ssh to AIX.

The problem with leading spaces in filenames, while ftp connection occurs when connecting to FTP servers on AIX 5.3.0.0 and 6.1.0.0. (other versions also may be affected)

I have noticed following relation: the files with additional space in name are ONLY the ones, which have NOT been modified at current day. In such cases the 'hh:mm' part of modification date is replaced by 'YYYY ' followed by additional space.

This problem occurs also in Midnight Commander, see bugs:
http://www.midnight-commander.org/ticket/2635
http://www.midnight-commander.org/ticket/2841

Other FTP clients works fine.

Reproducible: Always

Steps to Reproduce:
1.Start Krusader
2.Make FTP connection to some AIS Operating System host
3.Navigate with arrows to problematic directory, lets call it 'folder_name'
4.Press Enter
5.Error: Could not enter folder folder_name


Actual Results:  
5.Error: Could not enter folder folder_name

Expected Results:  
Krusader should be able to enter folder 'folder_name'. Access rights are OK.

As a workaround, user may type distant path manually in upper path bar, in that case Krusader enters directory 'folder_name' without problems. I will try to make short film showing that case.

Short film showing problem

As you can see on this film, some directories names in Krusader are shifted one character to the right. This is because Krusader thinks there is a space at the very beginning of directory name. This also breaks sorting order.

hard to test. Can you please check if this also happens with Dolphin.

Comment 3 Alex Bikadorov 2016-11-22 19:58:23 UTC

cannot test. Don't know if it Krusader related

Sorry, missed your previous reply. Why can't you test?
Maybe I can help?

Comment 5 Alex Bikadorov 2016-11-23 19:41:55 UTC

Well, I cannot reproduce this with a standard FTP server (tested with vsftpd). Do you know of one that shows this bug and is publicly accessible?

And
>Can you please check if this also happens with Dolphin.

This is important. It is maybe not a Krusader issue at all.

Sorry but I do not know any public AIX ftp servers.

This bug occurs also in Dolphin. This might indicate problem with some library.
Did you see movie I have attached to this bug?

Yep, KIO. Moved this bug.

Thank you for reporting this issue in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version?

If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you!

Just rechecked with AIX 7.2 and Krusader 2.7.2
Issue still persist. Symptoms are the same as before.
