1. The notification system

MoinMoin 1.7 includes a new notification system. Supplemental to the basic email based notification you can use a separate process running a Jabber/XMPP notification bot. See http://www.jabber.org/ and http://www.xmpp.org/ for more information on this protocol.

The bot can be used to send notifications about various events occuring in your Wiki, or to work with the Wiki interactively.

As it's a separate process, it doesn't block waiting for all notifications to be sent, so this solution should be suitable for large sites that have many users subscribed to particular changes.

1.1. Features

1.2. Notification options

When the notification_bot_uri option is present in your wiki's config, new options become available in your user preferences.

Make sure to set your JID in your user preferences.

A multi-selection list allows you to select which events you want to be notified about, and two new check-boxes let you specify if notifications should be sent via email, jabber or both.

1.3. Known main issues with the Jabber bot

1.3.1. You need a recent version of pyxmpp, 1.0 won't work

Either use a recent snapshot or get it directly from svn repository with:

           svn checkout http://pyxmpp.jajcus.net/svn/pyxmpp/trunk pyxmpp

Add the resulting pyxmpp directory to your PYTHONPATH or perform a "full installation" as described here:

           To build the package just invoke:
           python setup.py build

           To install it:
           python setup.py install

If you had some older version of PyXMPP it is better to uninstall it first (delete pyxmpp subdirectory of your site-packages directory) before installing the new version or things might not work correctly.

           You may also try:

           make install

1.3.2. Traffic limits

Jabber servers usually have rather tight data rate limits, so if your site generates a lot of traffic, the notification bot may become unstable and/or unusable. If such a condition occurs, you should consider running your own Jabber/XMPP server with relaxed limits.

1.3.3. Internationalization

For the i18n to work, your wiki must be accessible when the notification bot is being started.

1.4. Setting up a Jabber bot

These are step-by-step instructions you have to perform in order to get the Jabber notification bot up and running:

  1. Install a post-1.0 version of pyxmpp.

  2. The Jabber bot lives in a jabberbot/ directory in MoinMoin's distribution archive. Copy it to a suitable place. Make sure that PYTHONPATH environment variable contains the directory that contains the jabberbot package.

  3. Create an account for the bot to use using any Jabber/XMPP client. Currently it can't register the account by itself.
  4. Edit the bot's configuration file, config.py, and set its account details and a secret used to communicate with the wiki.

  5. Edit your wikiconfig and add notification_bot_uri and secret options to it. You will find an example in file wiki/config/more_samples/jabber_wikiconfig_snippet, distributed along with MoinMoin. Make sure to set the secret to exactly the same string as you used in the bot's configuration!

  6. Launch / restart your wiki.
  7. Launch the bot: python main.py
