Description Luke Horwell 2024-07-27 16:15:50 UTC 
SUMMARY

When a torrent is active, i.e. downloading or seeding, a file named "magnets" in ~/.local/share/ktorrent is persistently being written to in a loop. This causes the HDD activity indicator to be constantly flickering on/off.

The content of that file is just 2 bytes: "le". Happens even under a fresh configuration. No magnets are active.

STEPS TO REPRODUCE
1. Start a torrent, such as KDE Neon ISO.

STEPS TO DIAGNOSE
1. Install "inotifywait" package for the distro
2. Run "inotifywait -m -r /home/$USER/.local/share/ktorrent/"

WORKAROUND
Create a symbolic link for "magnets" to "/dev/null".

SOFTWARE/OS VERSIONS
OS: Arch Linux
KDE Plasma Version: 6.1.3
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION
- Still happens even if all plugins are disabled.
- Deleting the file immediately recreates it.
Comment 1 Luke Horwell 2024-07-27 16:17:02 UTC 
Forgot to add the output of inotifywait, if it helps:

```
/home/luke/.local/share/ktorrent/ OPEN magnets
/home/luke/.local/share/ktorrent/ MODIFY magnets
/home/luke/.local/share/ktorrent/ CLOSE_WRITE,CLOSE magnets
```
(repeated multiple times every second)
