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: MongoDB Storage Module
...

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

This is a storage backend that uses MongoDB. Depends on [luamongo
bindings](https://github.com/mwild1/luamongo)

This module is not under active development and has a number of issues
related to limitations in MongoDB. It is not suitable for production
use.

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

Copy the module to the prosody modules/plugins directory.

In Prosody's configuration file, set:

    storage = "mongodb"

MongoDB options are:

  Name         Description
  ------------ -------------------------------------------------------------------
  server       hostname:port
  username     your username for the given database
  password     your password for the given database (either raw or pre-digested)
  is\_digest   whether the password field has been pre-digested

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

  ------- ---------------------------
  trunk   Untested, but should work
