Re: [rdiff-backup-users] OverflowError: signed integer is greater than maximum

[Sai kee Wong]

Thanks for the reply.

Yes I did check the related pages.  And I tried to use the Python version
2.6 which I assume should not suffer from the problem.  But it does suffer.
At that time, I was using Mac OS 10.6 which is assumed to be 64 bits.
Until recently, test was done with Mac OS 10.8 with Python 2.7, still the
same problem.  So I made the fix.

B.Rgds

It looks like you were encountering the python bug identified here:

http://bugs.python.org/issue1747858

Before their fix, the uid was being converted to a (32 bit) signed int, 
which, as you have noted, isn't big enough.  After the fix, the uid is

After the orignal post, there is no feedback.  Recently, I tried to fix

 Believe it should be problem with the 64 bits OS. Tried python 2.6.1

 Segmentation fault
 
 Search through the rdiff-backup-users Archives but couldn't find

[Thomas fake Jakobi]

hi,

manual reply to this: 
http://www.mail-archive.com/rdiff-backup-users@nongnu.org/msg04953.html

 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 :)

you won't be able to. the code fixed in python is duplicated in rdiff-backup's 
cmodule.c, without the fix, if HAVE_LCHOWN is defined (which it probably is in 
these cases).

to replicate the fix you mentioned at 
http://svn.python.org/view/python/trunk/Modules/posixmodule.c?r1=77007r2=77006pathrev=77007
 you have to apply the attached patch to rdiff-backup.

this fixed the OverflowError on lchown for me.

regards,

fake

P.S.: in case of replies, please CC me, as i am not subscribed to the list.

   Hi Brad,
   
   This is a known problem that is due to a bug in Python. The Python bug

   it should be included in the latest Python releases: 2.5.4, 2.6.1, and

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

Re: [rdiff-backup-users] OverflowError: signed integer is greater than maximum

First of all, I really like rdiff-backup. In most cases (all but the
one I'll detail below), it's been great for me.

Searching in the mailing-list archives has led me to believe that
either the operating system version (64- versus 32-bit) or the python
version may be to blame here. The server I'm using as a backup
repository runs 64-bit CentOS 5. I'm using rdiff-backup *from* two
other servers, one with the same OS and one with 32-bit CentOS 4. The
64-bit machines run python 2.4.3, and the 32-bit has python 2.3.4,
which is the highest version in the Cent4 repos.

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:
