log files can overflow and fill up file system

Bug Description

Log files can grow very large [1], up to the point where they fill up / or /var with potentially disastrous results.

The MythTV packages use logrotate to rotate log files. While logrotate can rotate files based on their size, it is only run daily.

I suggest that mythtv-common should depend on a more sane log rotation utility. I'll try to find some alternatives.

I haven't been able to find a nice log rotation tool. Any hints? :)

According to the logrotate manpage we can use a size restriction and it looks like we can use both a size and daily rotate. I've added this fix to the mythtv-fixes branch.

logrotate is run *daily*. And on every run, it will rotate the log file anyways. Adding a file size restriction won't gain us anything AFAICT.

I'm setting this bug back to triaged.

At a minimum, all but the current log could be compressed. But otherwise, why is the current one not sane, and what would a "more sane" one do? Run every hour? Every minute? Every second? When there is a serious problem with the system, you're going to get serious logs! :-)

The only sane thing I can think to do is to offer to put the /var/log directory on its own filesystem so that it doesn't take down the whole system if it overflows. Moving to wishlist. If anyone can think of something better, feel free to propose something - this obviously wouldn't help people that install Mythbuntu over a standard Ubuntu install.

Bug #407894 (closed as a dup of this) points out that the behavior after the above change is that logs do not rotate daily now... logrotate can only make use of either size or daily rotation, not both... and size takes priority.

I agree with that bug that daily log rotation is preferred.
