Subject: byobu spawns apt-cache without end ... and freezes that way the system by high load

Date: Fri, 27 Jul 2012 13:09:12 +0200

Package: byobu

Version: 5.16-1

The bug is easy reproduceable ... open a terminal, su as another user,
start byobu ... and after a short while, you're load raises and
raises, while byobu fire's up one apt-cache after the next (in the
screenshot there are suddenly 30+ apt-cache's running in parallel).
Thanks to conky, I got for the  first time a clue, what happened.
The bug seems to be based on the option of byobu, to show how many
package updates are available.
On my wife's Ubuntu Precise and Quantal - this bug doesn't exist, so
on newer versions (5.17 Precise, 5.21 Quantal) it doesn't happen.

workaround: If I do the same with with tmux - instead of byobu - all
is safe. Also using screen instead of byobu is a functioning
workaround.

Package: byobu
Followup-For: Bug #682958
Control: tag -1 patch


Here is a patch that uses upstream revision 1952 (part of version 5.20).
It replaces the use of run-one with flock.
The package run-one being not part of Debian, there was little surprise
that we got this bug.
The use of flock from util-linux should prevent the launch of multiple
'apt-get' unwanted processes.
I am currently testing the change.
