The __hash__() methods of classes IPv4Interface and IPv6Interface had issue
of generating constant hash values of 32 and 128 respectively causing hash collisions.
The fix uses the hash() function to generate hash values for the objects
instead of XOR operation
* bits method and test_bits
* Cleaned up assert string
* blurb
* added docstring
* Faster method, per Eric Smith
* redoing as __format__
* added ipv6 method
* test cases and cleanup
* updated news
* cleanup and NEWS.d
* cleaned up old NEWS
* removed cut and paste leftover
* one more cleanup
* moved to regexp, moved away from v4- and v6-specific versions of __format__
* More cleanup, added ipv6 test cases
* more cleanup
* more cleanup
* cleanup
* cleanup
* cleanup per review, part 1
* addressed review comments around help string and regexp matching
* wrapped v6 test strings. contiguous integers: break at 72char. with underscores: break so that it looks clean.
* 's' and '' tests for pv4 and ipv6
* whitespace cleanup
* Remove trailing whitespace
* Remove more trailing whitespace
* Remove an excess blank line
IPv4Interface and IPv6Interface did not has netmask and hostmask
attributes when its argument is bytes or int.
This commit extracts method for constructors of Network and Interface,
and ensure Interface class always provides them.
Stop rejecting IPv4 octets with leading zeroes as ambiguously octal.
Plenty of other tools generate decimal IPv4 octets with leading zeroes,
so keeping this check hurts interoperability.
Patch by Joel Croteau.
the original logic was just comparing the network address
but this is wrong because if the network address is equal then
we need to compare the ip address for breaking the tie
add more ip_interface comparison tests
