Description Ulrich Drepper 2009-10-26 11:20:55 EDT
Description of problem:
Many log files libvirt creates in /var/log/libvirt/qemu/ have no content.  Still libvirt (or its helpers) "compress" them.  The result are nonzero-sized files.  Just don't do this, test for empty files first.  This will also prevent triggering other bugs (less, for instance, currently has problems showing such files).

Version-Release number of selected component (if applicable):
libvirt-0.6.2-18

How reproducible:
always

Steps to Reproduce:
1.run domain without any action for a few days
2.
3.
  
Actual results:
compress empty files

Expected results:
leave empty files alone

FYI this is already fixed upstream:

Switching to POST as per Cole's comment.
Comment 3 Mark McLoughlin 2009-10-29 13:27:41 EDT
Worth fixing for Fedora 12, but probably not worth the effort for Fedora 11.

Building now:

* Thu Oct 29 2009 Mark McLoughlin <markmc@redhat.com> - 0.7.1-15
- Avoid compressing small log files (#531030)

Will request tagging later
