This is a work in progress.

Python Gossip servers to share server state

This is mostly based off of Cassandra's implementaiton:
http://wiki.apache.org/cassandra/ArchitectureGossip
which is based on the paper:
http://www.cs.cornell.edu/home/rvr/papers/flowgossip.pdf

Requirements:
* Python
* Thrift
	thrift is used for serialization and asynchronous server messaging.
	You will need the thrift python libraries installed.
	http://incubator.apache.org/thrift/

Platform:
	Running locally on Python 2.6 on MacOSX 10.6

Quick and dirty run through:
	In the polyp directory:	
	$ thrift --gen py polyp.thrift
	$ thrift --gen py gossip.thrift
	$ sh test/test_spawn.sh
	Starting on port: 9990
	Starting on port: 9991
	Starting on port: 9992
	Starting on port: 9993
	Starting on port: 9999
	$ python interactive_client.py -g test/test.lst
	Starting polyp server en localhost:9000
	add_polyp <host>:<port> -- Add a polyp to the index
	get_state <polyp index> -- retrieve Polyp State information
	help -- display this message
	quit -- Exit the prompt
	show_polyps -- Show the polyps and their index
	> show_polyps
	0 :  ('localhost', 9990)
	1 :  ('localhost', 9991)
	2 :  ('localhost', 9992)
	3 :  ('localhost', 9993)
	4 :  ('localhost', 9999)
	> get_state 0
	GetStateMessage(endpoints=[Endpoint(port=9990, address='localhost'), Endpoint(port=9991, address='localhost'), Endpoint(port=9992, address='localhost'), Endpoint(port=9993, address='localhost'), Endpoint(port=9999, address='localhost')])
	> Status from localhost:9990
	localhost : 9990
		generation: 0	version:5
		{}
	localhost : 9991
		generation: 0	version:4
		{}
	localhost : 9992
		generation: 0	version:5
		{}
	localhost : 9993
		generation: 0	version:4
		{}
	localhost : 9999
		generation: 0	version:5
		{}
	quit
	$ sh test/kill_spawns.sh

Gossip activity for the test spawns is verbosely logged into test/*.log
