[rdiff-backup-users] UnboundLocalError on Windows XP

[Mark Hubbard]

Hi all,

Anybody else getting this?  I got this from
rdiff-backup-1.2.8-win32.zip, on Win XP SP2.  I don't think the file
server is the issue since the same destination file share is used to
rdiff-backup my other files and they don't fail.  Evidently it doesn't
like something that's within that one folder I'm trying to back up.

Any insight appreciated.  In the meantime I'll try to narrow it down to
specifically which files it doesn't like, but that could take a while.

I suspect this has to do with length of the path name, especially the
destination path name of the metadata, since it has extra path elements
& long file names automatically generated.  Some of my source data paths
are over 100 chars.  It's hard to tell, but I think the error comes from
some of those.  Windows only supports around 253 chars max.  I don't
have much of a choice of shortening the path to the source files.

Using -v higher than 3 just spews meaningless unrelated error messages
on every file, such as "can't retrieve ACL for xxxx".  So more verbosity
is useless in tracking down the exception that's actually killing the
program.

PS: the message "Found interrupted initial backup. Removing..." makes no
difference; it's only there because this isn't the first attempt.  I can
manually delete the destination folder & still get the same error on the
next attempt.
