Backing up from the 64-bit system works fine, and two of the
directories I'm backing up from the 32-bit system are fine as well.
However, one directory reports "OverflowError: signed integer is
greater than maximum" and quits partway through the backup. The
terminal output with the default verbosity is below; I can attach a
log with a higher verbosity if requested.

Hi Brad,

This is a known problem that is due to a bug in Python. The Python bug
has been fixed in their SVN, and was slated to be a part of 2.5.3, so
it should be included in the latest Python releases: 2.5.4, 2.6.1, and
3.0. Try upgrading your Python to 2.5.4 or 2.6.1.

Here is some more information about the problem:

https://bugs.launchpad.net/ubuntu/+source/rdiff-backup/+bug/245844
http://bugs.python.org/issue1747858

I have the same problem.
I'm on python26-2.6.4 with rdiff-backup-1.2.8,1
I just did :
# rm -rf /backup/users_backup/toto/rdiff-ba*
# rdiff-backup --force /mnt/users/toto /backup/Lipn/users_backup/toto
[...]
verflowError: signed integer is greater than maximum

I'm also on a 64 bit sys : FreeBSD 8.0-RELEASE AMD64

Posted: Sun Jan 17, 2010 10:42 am Post subject: OverflowError: signed integer is greater than maximum

I'm building a virtual machine like my save server.

I tried rdiff-backup-devel-1.3.3 and rdiff-backup-1.2.8,1 on this
virtual host and I've got the same error

So I did :

$ pkg_add gcc45
$ pkg_add -r librsync
$ wget http://savannah.nongnu.org/download/rdiff-backup/rdiff-backup-1.2.8.tar.gz
$ tar -zxvf rdiff-backup-1.2.8.tar.gz
$ cd rdiff-backup-1.2.8
$ cp ../cmodule.c .
$ python setup.py install --prefix=~/ --librsync-dir=/usr/local/include/librsync.h
--librsync-dir=/usr/local/include/librsync.h
running install
running build
running build_py
running build_ext

Ooops. That one is rdiff-backup's fault.

Replace the file cmodule.c with the one attached and re-compile.

What version of librsync are you using? Also is it just a cut and paste error
or are you specificing the --libsync-dir twice?

Cut past trouble :
# python setup.py install --librsync-dir=/usr/local/include/librsync.h

I use : librsync-0.9.7_2

But then there's http://bugs.python.org/issue6873, which indicates
that perhaps lchown still has the problem in the released Python
versions. If you can figure out how to reproduce it outside of
rdiff-backup the Python team would be grateful Smile
