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.

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

[Joe Steele]

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 
converted to a long.  I don't know anything about Mac OS X, but on 
linux, a long is either 32 bits or 64 bits, depending on the 
architecture.  Their fix should obviously work on 64 bit systems.  (And 
on 32 bit systems, it's probably unlikely that you will encounter 32 bit 
uids anyway.)


It also looks like their fix was implemented in python v2.5.3+, so I am 
a little puzzled as to why you were experiencing problems with the 
versions of python that you mention, if indeed you are using a 64 bit 
version.


In any case, it looks like you found a fix that works for you.

Fix:

After installed the rdiff-backup 1.3.3, find the file rpath.py
In Mac, it is in

/Library/Python/2.7/site-packages/rdiff_backup/rpath.py

At line 977, the line was

 else: os.chown(self.path, uid, gid)

change it to

 else: os.chown(self.path, int32(uid), int32(gid))

At line 46, add following

def int32(x):
 if x>0x:
 raise OverflowError
 if x>0x7FFF:
 x=int(0x1-x)
 if x<2147483648:
 return -x
 else:
 return -2147483648
 return x

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

[Sai kee Wong]

After the orignal post, there is no feedback.  Recently, I tried to fix
the problem.  I didn't know any about Python, started debugging by inserting
print statement.  Figured out in the Mac, some times it has file with uid
and gid set to 4294967294 (nobody).  It seems Python doesn't accept unsigned
32-bits.  And it crashed when calling the os.chown() with this high value.

I don't know how to make the os.chown() to accept unsigned int instead of
signed 32-bits int.  So I searched the web and add a function to change
too big value to -ve, in this case is -2.  Then it works.  As in previous
posts, somebodies asked similar questions and got no helpful response;
I published the solution here such that if anyone is suffering from the problem
can adopt the fix.

Also, please remind me if I am doing something wrong.

Fix:

After installed the rdiff-backup 1.3.3, find the file rpath.py
In Mac, it is in

/Library/Python/2.7/site-packages/rdiff_backup/rpath.py

At line 977, the line was

else: os.chown(self.path, uid, gid)

change it to

else: os.chown(self.path, int32(uid), int32(gid))

At line 46, add following

def int32(x):
if x>0x:
raise OverflowError
if x>0x7FFF:
x=int(0x1-x)
if x<2147483648:

return x

hi,

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

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=77007&r2=77006&pathrev=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.

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 :)

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

I use : librsync-0.9.7_2

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

[Michel Le Cocq]

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

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:
