Re: rdiff-backup 2.0.0 crashed the first time I ran it

[Walt Mankowski]

Hi everyone,

First I'd like to apologize for the terseness of my original post. It
was early Sunday morning when I wore up and discovered that my backup
had failed, and as a result I wasn't at my best.

I did some more poking at the problem and here's what I discovered (I
also posted this at the launchpad URL).

I modified get_indexpath() in log.py to catch a TypeError exception
and return the string "TypeError" instead of aborting. It printed 4
errors:

ListError: 'TypeError' [Errno 13] Permission denied: b'/run/user/1000/doc'
ListError: 'TypeError' [Errno 13] Permission denied: b'/run/user/1000/gvfs'
ListError: 'TypeError' [Errno 13] Permission denied: 
b'/run/user/1000/keybase/kbfs'
ListError: 'TypeError' [Errno 13] Permission denied: b'/run/user/141/gvfs'

I'm not really sure what's wrong with the first 3. Maybe they're odd
because they're in /run? The final file does really look like it might
be corrupted.

I ran the code in the debugger and was able to confirm that the data
in the rpath was bytes instead of strings. I wasn't able to find where
they were getting loaded.

At any rate it looks like the easy fix on my end is to exclude /run
from my backups. I did that last night and rdiff-backup ran without
errors.

Is there any other information you'd like me to provide to help track
down what's causing the problem?
