Description of problem: xmlrpclib.__version__ reports 1.0.1 from Python 2.7 in F14 and Python 2.6 in F12. I discovered this while trying to find a way to identify the version of xmlrpclib. The 2.7 xmlrpclib is not completely backward compatible with that in 2.6 Version-Release number of selected component (if applicable): python-2.7-7.fc14.x86_64 Steps to Reproduce: $ rpm -q python python-2.6.2-8.fc12.x86_64 [rcrit@puma freeipa-ca]$ python Python 2.6.2 (r262:71600, Jun 4 2010, 18:28:58) [GCC 4.4.3 20100127 (Red Hat 4.4.3-4)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import xmlrpclib >>> xmlrpclib.__version__ '1.0.1' $ rpm -q python python-2.7-7.fc14.x86_64 $ python Python 2.7 (r27:82500, Jul 26 2010, 18:19:48) [GCC 4.5.0 20100716 (Red Hat 4.5.0-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import xmlrpclib >>> xmlrpclib.__version__ '1.0.1'
This would unfortunately be an upstream issue. You can open a bug on http://bugs.python.org/ if you'd like to pursue it further. A workaround that I've had to use in other code is: import sys if sys.version_info[:2] >= (2, 7): # Set up things for python-2.7 stdlib pass else: # Set up things for python<2.7 stdlib This feels wrong as you aren't checking the xmlrpclib version directly but it's not too bad as the stdlib version should cover the individual modules that it ships.
