Unable to backup

[Alex Parkins]

Using Deja Dup version 10.1 and Duplicity version 0.6.00 I get the following error when I try to make a backup:

Failed with an unknown error:

Traceback (most recent call last):

Ken, this looks like a duplicity bug.

[Kenneth Loafman (kenneth-loafman)]

Actually, this is probably a 2-part problem. One is that src.name should be src_name, and the other is probably the read block size issue that Peter Schuller and I have been chasing.

[Peter Schuller (scode)]

At the very least running with the src name fix will show the first error (the strack trace above happens when another error happens, because the error handling code itself has the bug, thus hiding the original problem).

[Simon Lukell (slukell)]

I believe it should be self.src.name instead of src.name

[Alex Parkins (alexparkins)]

Well if I rename src.name to self.src.name on line 244 of dup_temp.py then I get the error:

Failed to read /home/aparkins/.cache/deja-dup/duplicity-full-signatures.20090620T075222Z.sigtar.part: (<type 'exceptions.MemoryError'>, MemoryError(), <traceback object at 0xa2dc57c>)

Yes, this is the real error. The src.name thing was an error in the
error handling path. Fixes to both issues are in the branch:

   https://code.launchpad.net/~scode/duplicity/reasonable-io-blocksize

And is pending approval/merge.
