CHARUN - A python bridge to CouchDB
http://github.com/kr1/charun

ABOUT

CHARUN is a server that listens on a UDP socket for incoming json-formatted data which is transformed in python objects, manipulated and sent to a couchdb instance. Think of it as a doorman.
Intended use cases are: logging app data which has to be filtered, aggregated or otherwise tagged before being stored.

It is written in python and uses uses the twisted framework. The basic modules are:

1. charun

   holds the code that handles incoming data.

2. CouchDBConnect

   couchdb related code for connection and storage

3. charun_tac.py

   application configuration (twisted.application) that holds all connection informations, database names.

INSTALLATION

1. dependencies

   you need to have python and the twisted framework installed. furthermore, you need a couchdb instance to write to.
   And if you want to run the tests you need the Mock module and the unittest2 module.

2. How to run

   run charun as a daemon with:
   twistd -y charun_tac.py

   it will log to the tmp directory and will write its pid to a file called twistd.pid to the current directory.
   stop the application with:
   kill `cat twistd.pid`

   you can run the application in foreground with:
   twistd -noy charun_tac.py

3. run the tests

   nosetests will discover the tests automatically, just run:
   nosetests -v

   if you want more control over which tests to run:
   you can run all tests by calling:
   python test_director.py
   you can run only unit tests:
   python test_director.py unit
   or only integration tests:
   python test_director.py integration
