Comment 0 for bug 1005901

I've experienced issues restoring backups when /tmp is tmpfs partition. I've tried this on older (0.6.15) and latest duplicity (0.6.19), python 2.4.2 (CentOS 5 default), python 2.7.3 (built from source) and it's always using /tmp for some parts of the process while I specifically define TMPDIR which is taken in effect somewhat.

during earlier stages of restore, it doesn't use /tmp and suddenly starts using /tmp. lsof reports the file in /tmp is deleted and I can't actually see what's it's doing there. Here's debug (9) output of the restore process when this happens:

I first thought this was something in python itself defaulting to /tmp, but it also happened on newest python too so I'm fairly sure duplicity fails here. I'm only starting learning python so can't debug more/write patches so I depend on you guys.

lsof output looks like this:
