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.
- 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
import socketcache
host = socketcache.UDPSocketCache("example.com", 12345)
# Reuse host object.
(sock, addr) = host.get()
sock.sendto("Hello!", addr)- 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
$ Unknown.
