mod_cloud_notify_encrypted: Ensure body substring remains valid UTF-8 The `body:sub()` call risks splitting the string in the middle of a multi-byte UTF-8 sequence. This should have been caught by util.stanza validation, but that would have caused some havoc, at the very least causing the notification to not be sent. There have been no reports of this happening. Likely because this module isn't widely deployed among users with languages that use many longer UTF-8 sequences. The util.encodings.utf8.valid() function is O(n) where only the last sequence really needs to be checked, but it's in C and expected to be fast.

summary: A CouchDB backend for Prosody
...

***Note:** This module needs updating to the 0.8 storage module API.*

Introduction
============

This is an experimental Prosody backend for CouchDB.

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

In your config file, under the relevant host, add:

    datastore = "couchdb";
    couchdb_url = "http://127.0.0.1:5984/database-name";

Compatibility
=============

This module was developed as a prototype during development of the
storage provider API in Prosody 0.8. The final storage provider API is
different, so this module needs updates to work.

Quirks
======

This implementation is a work in progress.

-   The data stored in couchdb is limited to: account data, rosters,
    private XML and vCards
