+++ This bug was initially created as a clone of Bug #709701 +++ Description of problem: If an IPNetwork object is instantiated with bad data, the python-netaddr code tries to access an unbound local variable. It should raise an appropriate exception instead. This means that a user of python-netaddr must check for all exceptions instead of just expecting netaddr.core.AddrFormatError. Version-Release number of selected component (if applicable): python-netaddr-0.7.5-2 How reproducible: always Steps to Reproduce: 1. python -c "import netaddr; netaddr.IPNetwork('3333/32')" Actual results: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/site-packages/netaddr/ip/__init__.py", line 919, in __init__ implicit_prefix, flags) File "/usr/lib/python2.7/site-packages/netaddr/ip/__init__.py", line 782, in parse_ip_network value = ip._value UnboundLocalError: local variable 'ip' referenced before assignment Expected results: Traceback (most recent call last): File "<string>", line 1, in <module> File "/usr/lib/python2.7/site-packages/netaddr/ip/__init__.py", line 926, in __init__ raise AddrFormatError('invalid IPNetwork %s' % addr) netaddr.core.AddrFormatError: invalid IPNetwork 3333/32 Additional info: Upstream was tracking this as issue #2 and #5 in github --- Additional comment from updates on 2011-06-02 02:08:36 EDT --- python-netaddr-0.7.5-3.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/python-netaddr-0.7.5-3.fc15 --- Additional comment from updates on 2011-06-03 01:28:04 EDT --- Package python-netaddr-0.7.5-3.fc15: * should fix your issue, * was pushed to the Fedora 15 testing repository, * should be available at your local mirror within two days.
