Here are my problems with this approach:
* There is no indication in the GUI that debug is enabled. The option
is greyed out. If debug was enabled by default but the GUI showed it
as enabled (and it could be disabled there) that would be much more
acceptable.
* A responsible package should be dealing with its log files in a
better fashion. Policy 10.8 says they should be in /var/log (probably
/var/log/xbmc/ for XBMC) and be rotated occasionally, ideally with
logrotate.
* The logging of each and every remote keypress is a security concern
as it means that password entry is recorded.
* It is not unreasonable to want to limit unnecessary logging output,
especially that which "can pretty much only be deciphered by a
developer or long time XBMC/Kodi power user"[0]
Looking at my XBMC which was started less than 2 days ago and breaking
down the log entry types I see:
9 WARNING:
78 ERROR:
320 INFO:
390 NOTICE:
7366 DEBUG:
This debug output is considerable compared to the normal output. I
understand the desire to have the debugging enabled by default to ease
support, but the GUI configuration should be showing this is the case
and it should be possible to turn it off.
