Requirements
============

- Twisted >= 8.0.1:
   - Twisted Core
   - Twisted Words
- uuid.py (Python 2.5 std. lib. or http://pypi.python.org/pypi/uuid)
- Wokkel >= 0.5.0 (http://wokkel.ik.nu/)
- A Jabber server that supports the component protocol (XEP-0114),
  and, to enable the micro-blogging feature, the remote roster
  management protocol (XEP-0321). We recommend using Prosody.

For the PostgreSQL backend, the following is also required:

- PostgreSQL
- Psycopg 2


Installation
============

sat_pubsub uses setuptools for package building and installing.
To build from the source run:

  python setup.py build

Then, to install run the following, possibly as root:

  python setup.py install

See the setuptools documentation for further information on changing
installation locations.


Configuration
=============

sat_pubsub uses Twisted's twistd command for running its services. Starting with
Twisted 2.5.0, twistd supports running Twisted Application Plugins directly,
without the use of mktap. In Twisted 8.1.0, the use of mktap for configuration
is deprecated.

Idavoll, on which sat_pubsub is based, provides two types of storage for the backend:
a memory-based storage facility, which is volatile, and a persistent storage facility
using PostgreSQL. For now, sat_pubsub only uses the persistent storage facility.

For using the PostgreSQL backend, create a database (for example named pubsub):

  sudo -u postgres createuser -d -P `whoami`
  createdb pubsub
  psql pubsub < sat_pubsub/db/pubsub.sql


Your Jabber server must also be configured to accept component connections and,
to enable the micro-blogging feature, remote roster management. See below for details.


Running sat_pubsub
==================

The minimal example for running sat_pubsub is:

  twistd sat_pubsub

This will start the service and run it in the background. It generates a
file twistd.pid that holds the PID of the service and a log file twistd.log.
The twistd utility has a fair number of options that might be useful, and
can be viewed with:

  twistd --help

When the service starts, it will connect to the Jabber server at the local
machine using the component protocol, and assumes the JID 'pubsub'. This
assumes a couple of defaults which can be overridden by passing parameters to
the twistd plugin. You can get an overview of the parameters and their defaults
using:

  twistd sat_pubsub --help

In particular, the following parameters will be of interest:

 --jid: The Jabber ID the component will assume.
 --rport: the port number of the Jabber server to connect to
 --secret: the secret used to authenticate with the Jabber server.

For example:

  twistd sat_pubsub --jid=sat-pubsub.<xmpp_domain> --secret=<password>

You may also want to provide the --verbose flag to see the traffic flow,
for example to debug the configuration. Below some specifics for the
Prosody XMPP server implementation.


Running sat_pubsub with Prosody 
===============================

To enable the micro-blogging feature with Prosody XMPP server, you need
the remote_roster plugin. Check if the remote_roster plugin is already
in your Prosody installation:

  cd prosody/plugins
  ls mod_remote_roster.lua

If you can't see it, download it from here:

  wget http://prosody-modules.googlecode.com/hg/mod_remote_roster/mod_remote_roster.lua

You need to patch the file (commenting two lines to make all contacts available):

  wget http://paste.debian.net/download/12106
  patch -p2 < paste_1206

Edit the prosodi.cfg.lua file to add this module:

  modules_enabled = {
                [...]
                "remote_roster";
                [...]
  }

Also add these two lines at the end of the file, adapting them to your XMPP server
domain (virtual host) and selecting a password of your choice:

  Component "sat-pubsub.<xmpp_domain>"
          component_secret = "<password>"

For a more complete installation and configuration of Prosody to be used with
sat_pubsub, please report yourself to the Salut à Toi wiki:
