'RORPath instance has no attribute 'path'' raised of class '<type 'exceptions.AttributeError'>' about rdiff-backup

[isalgueiro]

I no longer use rdiff-backup.

I've experienced this error as well in the past, though I didn't make a note of exactly what I was doing at the time. Please reopen the issue, at least until it's received a response from the developer.

Re-opening so we know to investigate it. @mhsmith how did you get around it at the time?

[mhsmith]

I'm sorry, I don't remember. All I can tell you is I was running on Cygwin on Windows 7, and probably wasn't using any command-line options except --exclude-globbing-filelist. I don't think I've ever used --no-acls.

I got this error message when I ran sudo rdiff-backup … instead of doing sudo su and then rdiff-backup ….

[mhsmith]

Today I tried to use the build from http://savannah.nongnu.org/download/rdiff-backup/rdiff-backup-1.2.8-win32.zip rather than the build provided by Cygwin, and I received this exact error.

Before that, I received the following messages:

Warning: Windows Access Control List file not found
UpdateError: <filename redacted> changed from regular file before signature 
[this line was repeated several times, always for files with non-ASCII filenames]

I did not find any workaround other than going back to the Cygwin build.

I faced same error message:

AttributeError: RORPath instance has no attribute 'path'

And command is /usr/bin/rdiff-backup --print-statistics --exclude-filelist exclude.log /home/user /media/backup/home-user

And the reason it may have failed is that script was previously started as regular user and it was now the first time I run script with sudo.

The issue is still there but it does only happen when another issue happens (I guess wrong or unreachable directory). RORPath class has indeed no attribute path hence the lines around 783 in src/rdiff/backup.py are wrong:

        assert diff_rorp.isdir() or self.base_rp.isdir(), \
          ("Either %s or %s must be a directory" % (repr(diff_rorp.path),

Replacing it with diff_rorp.get_safeindexpath() should solve the issue. I'll fix it once #60 is closed.
