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.
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)

Git commit 4510509950c10beda3ff7d409efe8f33a71d9ebc by Jack Hill. Committed on 08/08/2025 at 22:56. Pushed by jackh into branch 'master'. Fix issue of constantly writing to the magnets file. Basically MagnetManager was constantly emitting `update`, even if it hadn't updated. I've removed the bad emit and added a test to ensure the signal is only emitted when needed.
