python-socketcache

A simple pure python cache of UDP socket objects, supporting a custom TTL, IPv{4,6} and random balancing.

Intended to assist in sending a lot of UDP packets to a host addressed by FQDN without burdening the local resolver. The local machine may not have a caching resolver at all, making it a good idea for the application to manage a cache itself.

Features

• Configurable TTL (though it is not pulled from the DNS records)
• IPv4 and IPv6 support, both optional
• Prefers IPv6 where both the local system supports IPv6 and AAAA records exist
• Supports random address choice for round-robin load balancing
• Pure Python
• Debian/Ubuntu package
• Comes with tests

Example

import socketcache

host = socketcache.UDPSocketCache("example.com", 12345)

# Reuse host object.
(sock, addr) = host.get()
sock.sendto("Hello!", addr)

Building a new package

• Don't forget to update _version_ in src/socketcache.py and add a new version block to debian/changelog - the build will fail if the versions don't match.
• dpkg-buildpackage -tc
• Run lint checks:

$ lintian python-socketcache_0.1.0_all.deb
$
