Purpose

These are reasons to use Prosody Jabber/XMPP server:

be humble for consuming memory and CPU resources, especially for the Sugar Server Kit usecase (up to 1K users),
jabber server should be simple to initially configure, and work in an unmaintained mode as long as possible.

Plugins

These plugins are tested against the Prosody 0.8.2 version.

mod_sugar_roster

Provides a global roster, where every user sees all registered accounts.

mod_sugar_pep

In difference with the original mod_pep plugin, mod_sugar_pep allows all buddies from the sugar roster to get all notifications, even without proper subscriptions. This plugin seems to be a workaround, because subscription should be done on the client side, but that doesn't happen. The affected use case can be reproduced in the Glucose-0.88 (Dextrose-2) environment:

Clean up data/ directory;
Start XO #1;
Start XO #2;
Create and share activity instance on XO #2;
Neighborhood view on XO #1 doesn't show shared activity;
Sharing activity on XO #1, is visible from XO #2.

In over words, XO #1 is not subscribed to PEP notifications from XO #2.

mod_sugar_muc

The only difference compared with the original mod_muc plugin is a workaround for the telepathy-gabble/Prosody issue.

This plugin should be used instead of mod_muc until the issue is fixed in telepathy-gabble or in Prosody.

Installation

To reuse sugar plugins, copy them to the directory with Prosody plugins. Or, install the prosody-sugar package from the Sweets Distribution repository.

Configuration

See sugar-server-templates sources for a configuration example.
