duplicity cannot back up files from Russian file directory

Bug #1313966 reported by Özgür on 2014-04-28
This bug affects 2 people
Affects Status Importance Assigned to Milestone
duplicity (Ubuntu)

Bug Description


Any user of the gio backend in duplicity (used by Deja Dup) backing up to a directory with utf8 characters in it is unable to complete a single backup.

[Test Case]

mkdir /tmp/source
echo test > /tmp/source/test
mkdir /tmp/Ж
duplicity --gio --no-encryption /tmp/source file:///tmp/Ж

[Regression Potential]

The upstream patch to fix this mostly affects various exception or logging code paths. But each one is pretty simple change (just upgrading ascii to unicode).

[Original Report]

After upgrading to Ubuntu 14.04 from 13.10, Duplicity cannot backup files. The location it will backup and the location to backup have both Russian characters in path. I believe this is the reason of the problem.

After failure, duplicity shows this log:
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1494, in <module>
  File "/usr/bin/duplicity", line 1488, in with_tempdir

    return fn(*args, **kwargs)
  File "/usr/lib/python2.7/dist-packages/duplicity/backends/giobackend.py", line 130, in copy_file
    log.Info(_("Writing %s") % target.get_parse_name())
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 36: ordinal not in range(128)

I believe the related script shall be fixed with "u" prefix, as explained here:

Upstream has fixed this in trunk coincidentally already, by moving the "Writing %s" line elsewhere and not using the full path name.

Thanks a lot Brian, Kenneth, Michael and anyone who has contributed to the solution.
It works fine for me. duplicity backed up the same location after upgrading to proposed version.

    - Fix a couple more encoding issues during exception handling. These
      bits aren't as critical, but are bundled in same patch from upstream
      and are still useful. LP: #1289288, LP: #1311176
