Package: py-radix-sr
This is a PyPI package of theSEKOIA.io forkof the py-radix library.
Version 1.0.0post1 is git version 682a1b96fb5b9599bc4baf11c0ab08b2be4fe783.The original was forked by Raphael Cohen to reduce the memory footprint of the C implementation, and has several other fixes since. This particular PyPI package was published by Sasha Romijn.The following attributes have been converted to properties and will be computed at query time:networkprefixThedataobject is nowNoneby default instead of being an empty dict. It can be used to store any type of data.py-radix implements the radix tree data structure for the storage and
retrieval of IPv4 and IPv6 network prefixes.The radix tree is commonly used for routing table lookups. It efficiently
stores network prefixes of varying lengths and allows fast lookups of
containing networks.InstallationInstallation is a breeze via pip:pip install py-radixOr with the standard Python distutils incantation:python setup.py build
python setup.py installThe C extension will be built for supported python versions. If you do not
want the C extension, set the environment variableRADIX_NO_EXT=1.Tests are in thetests/directory and can be run withpython setup.py nosetests.UsageA simple example that demonstrates most of the features:import socket
import radix

# Create a new tree
rtree = radix.Radix()

# Adding a node returns a RadixNode object. You can create
# arbitrary members in its 'data' dict to store your data
rnode = rtree.add("10.0.0.0/8")
rnode.data = {"blah": "whatever you want"}

# You can specify nodes as CIDR addresses, or networks with
# separate mask lengths. The following three invocations are
# identical:
rnode = rtree.add("10.0.0.0/16")
rnode = rtree.add("10.0.0.0", 16)
rnode = rtree.add(network = "10.0.0.0", masklen = 16)

# It is also possible to specify nodes using binary packed
# addresses, such as those returned by the socket module
# functions. In this case, the radix module will assume that
# a four-byte address is an IPv4 address and a sixteen-byte
# address is an IPv6 address. For example:
binary_addr = socket.inet_aton("172.18.22.0")
rnode = rtree.add(packed = binary_addr, masklen = 23)

# Exact search will only return prefixes you have entered
# You can use all of the above ways to specify the address
rnode = rtree.search_exact("10.0.0.0/8")
# Get your data back out
print(rnode.data["blah"])
# Use a packed address
addr = socket.inet_aton("10.0.0.0")
rnode = rtree.search_exact(packed = addr, masklen = 8)

# Best-match search will return the longest matching prefix
# that contains the search term (routing-style lookup)
rnode = rtree.search_best("10.123.45.6")

# Worst-search will return the shortest matching prefix
# that contains the search term (inverse routing-style lookup)
rnode = rtree.search_worst("10.123.45.6")

# Covered search will return all prefixes inside the given
# search term, as a list (including the search term itself,
# if present in the tree)
rnodes = rtree.search_covered("10.123.0.0/16")

# There are a couple of implicit members of a RadixNode:
print(rnode.network)     # -> "10.0.0.0"
print(rnode.prefix)      # -> "10.0.0.0/8"
print(rnode.prefixlen)   # -> 8
print(rnode.family)      # -> socket.AF_INET
print(rnode.packed)      # -> '\n\x00\x00\x00'

# IPv6 prefixes are fully supported in the same tree
rnode = rtree.add("2001:DB8::/3")
rnode = rtree.add("::/0")

# Use the nodes() method to return all RadixNodes created
nodes = rtree.nodes()
for rnode in nodes:
        print(rnode.prefix)

# The prefixes() method will return all the prefixes (as a
# list of strings) that have been entered
prefixes = rtree.prefixes()

# You can also directly iterate over the tree itself
# this would save some memory if the tree is big
# NB. Don't modify the tree (add or delete nodes) while
# iterating otherwise you will abort the iteration and
# receive a RuntimeWarning. Changing a node's data dict
# is permitted.
