The problem is easy to reproduce:
>>> import xdrlib
>>> p = xdrlib.Packer()
>>> p.pack_int(-1)
__main__:1: DeprecationWarning: struct integer overflow masking is deprecated
The cause is xdrlib.Packer uses the same pack operation for both
signed and unsigned integers...
def pack_uint(self, x):
self.__buf.write(struct.pack('>L', x))
pack_int = pack_uint
...and the unsigned struct.pack('>L', x) gags on the negative value.

Thanks for the report. This actually raises an error with current Pythons:
2.7 traceback: File "xdrlib.py", line 54, in pack_uint
self.__buf.write(struct.pack('>L', x))
struct.error: integer out of range for 'L' format code
(The 3.x error message is slightly less helpful: “struct.error: argument out of range”).
Would you like to make a patch for this?
Bug triage tips: 2.6 only gets security fixes, bugs are not fixed there anymore. “Extension modules” are modules written in C, like time; Python modules map to the “Library” component.

New changeset d3f9a6d7f6e4 by Mark Dickinson in branch '2.7': Issue #9696: Fix exception incorrectly raised by xdrlib.Packer.pack_int when trying to pack a negative (in-range) integer. http://hg.python.org/cpython/rev/d3f9a6d7f6e4 |

I believe this should be applied also against 3.3. I was working on this using 3.3 code base, so it is not working there too. |
