Description Peter 2020-06-09 12:26:04 UTC

SUMMARY
KDE 5 is a great distro. Great interface, very convenient and customizable. And I like it until I start working with the network using KIO + Dolphin:
- ssh / ftp do not reconnect when a failure occurs;
- copying via ssh / ftp is very slow;
- when editing a file on the server, a million messages appear with VSCode with questions about saving and overwriting files;
- When working with network files, KIO throws a lot of useless messages in the notification area.

Now I have discovered another problem related to WebDAV. When copying a large file to the server, an error occurs in 100% of cases.
I did not pay attention to this before, as I thought that this was related to the server settings. But yesterday I burned ubuntu to usb and checked copying files from 1 to 2 GB in size on the server. 5 out of 5 cases were successful.

The link contains a video with the beginning of the copying process https://youtu.be/445npK14Eq0, after the video ends in three minutes a connection error will be issued.

STEPS TO REPRODUCE
1. Connect to the server via WebDAV and copy a large file (> 500 Mb) to it.
2. See the fake copy speed, as in the video. My connection is limited to 100 Mb/s, while copying it shows 130 Mb/s, sometimes 160 Mb/s.
3. Wait and get the "connection was disconnected" error.

OBSERVED RESULT
Connection error while copying large files via WebDAV.

EXPECTED RESULT
I really hope that KIO FUSE will be implemented as soon as possible.

ADDITIONAL INFORMATION

KIO-fuse is already implemented and you can test the beta if you want. KDE is a community, not a distro.

Comment 2 Peter 2020-06-10 20:45:17 UTC

I put it wrong, not distro, but DE.
Question. How to put a beta version? I did not find the necessary information on https://neon.kde.org/

Comment 3 Nate Graham 2020-06-10 21:05:42 UTC

KDE is a community, not a DE. :) Plasma is the DE.

You can use Neon unstable edition, which has kio-fuse packages, I believe. It's also on openSUSE Tumbleweed, which is what I'm using

Comment 4 Gery 2023-08-17 17:54:39 UTC

Unfortunately, I still experience this issue with kio-fuse installed on neon with KDE 5.27.7 and frameworks 5.109.0.

Comment 5 Méven Car 2024-10-31 14:51:40 UTC

Could an HTTP timeout.
In http(and webdav) connections limited timespan.

We might need to restart/resume downloads of big files.

Can you copy or screenshot the error.
Can you reproduce the problem while launching dolphin from a terminal and see if there is outputs when the issue occurs.
