Description Carl-Johan Kjellander 2010-04-25 16:55:00 UTC

Description of problem:
For weeks yumBackend.py has been running against my
disks at an average if 85 MB/s. It or packagekitd
seems to be stuck in an infinite loop checking for
updates or something.

Version-Release number of selected component (if applicable):
# packagekit-bugreport.sh
Distro version:       Fedora release 12 (Constantine)
PackageKit version:   0.5.7
PackageKit Process Information:
root     10534  0.0  0.1 185104  4996 ?        Sl   17:50   0:03 /usr/sbin/packagekitd


How reproducible:
It is intermittent, but seems to loop over and over
every 40-50 seconds.

Steps to Reproduce:
1. Boot and login.
2. Wait and watch io with gkrellm.

  
Actual results:
It should check once per day, and a yum check shouldn't
take more than a minute.

Expected results:
It loops and loops for hours on end, and then says
188 updates or something similar and quits looping.

You update those, reboot, and then at some later point
it starts looping again.

There is nothing in the logs about yum or packagekit.

Comment 1 Carl-Johan Kjellander 2010-04-25 16:57:28 UTC

Oh, and it is persistent after reboots.

Comment 2 Richard Hughes 2010-04-26 12:29:36 UTC

Can you please do:

killall python
sudo /usr/share/PackageKit/helpers/yum/yumBackend.py get-updates none

And then print the output of the looping. Thanks.

Comment 4 Richard Hughes 2010-04-26 15:58:23 UTC

Reassigning to the yum guys for ideas. Feel free to re-assign back if you think it's something insane we're doing in PK.

Comment 5 seth vidal 2010-04-26 16:06:59 UTC

what ver of yum?

I expect it is the metadata reget bug.

Comment 6 Carl-Johan Kjellander 2010-04-26 18:01:57 UTC

yum-3.2.27-2.fc12.noarch

Comment 7 Carl-Johan Kjellander 2010-04-26 18:03:18 UTC

And this started happening some time during this spring. I've just haven't reported it. So it has been going on for a few weeks at least.

Comment 8 seth vidal 2010-04-26 18:09:23 UTC

grab yum-3.2.27-3.fc12, please. I think that will fix this.

Comment 9 Carl-Johan Kjellander 2010-04-26 18:25:26 UTC

I tested yum-3.2.27-3.fc12.noarch as per bug #577497 so it
is probably a dupe. But that bug shouldn't have been CLOSED
ERRATA before it was in stable for fc12.

Suggest marking this as dupe but reopening bug #577497.

Comment 10 seth vidal 2010-04-29 18:27:50 UTC

thanks - marking as a dupe and 3.2.27-3.fc12 is now pushed to stable.

sorry about the premature closing.
