Description peter.hine 2009-09-10 01:50:58 UTC

Version:           2.0.0 "Mars Pathfinder" (using 4.3.1 (KDE 4.3.1) "release 163", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.29-0.1-pae

Copying a file (using F5) from sftp session to another sftp session preserves time/date.
Doing same in "synchronize Directories" does not preserve time/date.

thanks
H

Copying from FTP -> Local hdd does not preserve date. (Dolphin/Krusader)
Syncronizing FTP <> Local hdd does preserve date. (Krusader)

Please add a log file for kio_sftp

Andreas: You should be able to produce that log yourself. Or are you saying that preserving timestamps over sftp works for you?

Comment 6 Andreas Schneider 2013-03-21 09:35:27 UTC

Preserving timestamps means that you call sftp_utimes() after it has been transferred. Which works just fine if you SFTP server supports it.

The put() command of the sftp kio slave supports setting modifications times but doesn't give an error if it doesn't work. We probably need a libssh log to see what's going on. Maybe also log an error if we can't set it.
