Cannot get working on Windows 7, v2.7.14

• mkdir test1
• virtualenv test1
• test1\scripts\activate
• pip install py-radix (--> Successfully installed py-radix-0.10.0)
• python (--> Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [MSC v.1500 32 bit (Intel)] on win32)

Am I doing something wrong? Please let me know if you need additional details or would like me to try something.

I cloned the repo and set it up without C extensions. Using the same setup as above I get this:

>>> import radix
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build\bdist.win32\egg\radix\__init__.py", line 4, in <module>
  File "build\bdist.win32\egg\radix\radix.py", line 1, in <module>
ImportError: cannot import name inet_pton

The fix for this is to pip install win_inet_pton (inet_pton isn't available in the stdlib socket on Windows for 2.x):

>>> import socket
>>> socket.inet_pton
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'inet_pton'

Once I do this, I can get it to work:

>>> import win_inet_pton
>>> import radix
>>> rtree = radix.Radix()
>>> rnode = rtree.add("10.0.0.0/8")

I thought this might be fixed in Python 3.4+ as described in issue 7171. If I check in Python 3.6, I can see that inet_pton is now included in the stdlib socket:

>>> import socket
>>> socket.inet_pton
<built-in function inet_pton>

However, I still get the same error in 3.6.3 on Windows 7:

> python
Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 17:26:49) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import radix
>>> rtree = radix.Radix()
>>> rnode = rtree.add("10.0.0.0/8")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: Either the application has not called WSAStartup, or WSAStartup failed.
>>>

But, if I clone the repo and build this without C extensions it does work correctly in 3.6 on Windows. So, there must be some difference in the way inet_pton works on Windows vs. POSIX systems.

Note - as with Python 2.7, installing the package win_inet_pton and importing it before py-radix fixes the issue (if using C extensions).

Thanks for the information. I don't have a windows platform to test this on so I can't be much help on that front.

I'd certainly prefer to not have an external dependency on win_inet_pton as part of this, so perhaps an addition in the README to that effect for Windows platforms.

If you feel compelled to make a PR to fix support for Windows I would gladly accept it. (If it has a regression test runner system like appveyor.yml which I've not gotten to work that would be better.)

Also, if that is only needed for Windows? requirements in setup.py can be platform-dependent.

@mjschultz I'm not a C programmer, so I can't help with a solution to make the C extension Windows compatible without using win_inet_pton. However, if you would be willing to accept a PR to setup.py (per @wagner-certat's suggestion) and the README.rst I might be willing to take a stab at that. Please let me know.
