[Aptitude-devel] Bug#764046: aptitude: race condition in config file replacement leads to warnings

Package: aptitude
Version: 0.6.11-1
Severity: normal
Usertags: warnings race-condition

I run several cron jobs each doing aptitude searches and I often get
this warning from aptitude:

E: Unable to replace /home/pabs/.aptitude/config with new configuration file - apt_init (2: No such file or directory)

Looking at the code it seems that there is a race condition when
multiple aptitude instances are running:


Every instance is using ~/.aptitude/config.new instead of creating a
temporary unique filename. This means that one process can rename
the .new file before another process gets a chance to do that, which
means the .new file disappears, rename fails and a warning is given.
