Description Jens Petersen 2019-02-19 07:41:28 UTC

Description of problem:
During a Workstation install failure (due to an rpm failing to download)
I noticed that /tmp was 100% full due to /tmp/dnf.librepo.log
being 975MB!

Version-Release number of selected component (if applicable):
anaconda-29.19.0.34-1.el8

Steps to Reproduce:
1. Net install of RHEL 8 (Workstation)
2. Look at Diskspace in /tmp partition.

Actual results:
In my case having downloaded about 77% of the packages
I noticed that /tmp was 100% with dnf.librepo.log taking up 975MB!

The file has about 8 million lines with select_next_target!! ;)

Expected results:
/tmp not to overfill during installation.

Additional info:
I am not sure if this is fatal or how reproducible but I thought
I better report it anyway, since it doesn't seem good.

Comment 1 Jens Petersen 2019-02-19 08:35:03 UTC

Okay well I just tried again and successfully netinstalled (exact same RHEL 8 WS config)
and dnf.librepo.log was only 1.6MB...

Thanks for the report. It is good to know that the log file could grow so large.

I see this as a proposal on DNF to avoid such a grow of the log.

Definitely - seems to me like a debugging message that was left in place by mistake.

originally reported on Fedora/dnf bug 1580022
on RHEL 8 Beta I ended up with > 7 GB DEBUG level lines in dnf.librepo.log:
-rw-r--r--. 1 root   root   7376408576 Mar 19 16:20 dnf.librepo.log

Comment 7 Lukáš Hrázký 2019-03-27 19:06:58 UTC

Pull requests:
https://github.com/rpm-software-management/libdnf/pull/707
https://github.com/rpm-software-management/dnf/pull/1363

These turn off debug logging for librepo by default. There are other log files, the logging is fragmented and not in great shape in general. I hope we'll revisit it in the future with a more complete solution.
