Description Lastique 2020-12-13 22:35:49 UTC 
SUMMARY

Please, provide an option to disable logging in ~/.local/share/ktorrent. During the normal operation, logs are not necessary, and simply waste space and issue unnecessary writes to the disk, which can be harmful for SSDs.

The logging is fairly intensive as well. For example, on my system with ~150 seeding torrents I can see a few dozens (30-60) log records per second. I'm assuming, logging intensity depends on the network activity and can easily go even higher.

Seems like the bug janitor but didn't work so I will post the details here:

Git commit 1d15b7d578da30864e9de70523ba6854f525955f by Andrey Semashev.
Committed on 11/11/2023 at 01:13.
Pushed by stikonas into branch 'master'.

Disable logging by default and add --enable-logging command line option.

Logging is not useful during normal operation of the program and only
generates unnecessary writes to the filesystem and periodic CPU load
when the log files are compressed. So disable logging by default.

Provide the --enable-logging command line option to enable logging
back. The option is now also required to enable logging on console
(which is further enabled by --verbose).
