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: Manually specify SRV records
...

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

This Prosody plugin lets you manually override SRV records used for a
remote host.

Usage
=====

Simply add `"srvinjection"` to your `modules_enabled` list to enable.
Then add the `srvinjection` option to the global section.

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

The `srvinjection` option can be used as follows:

    srvinjection = {
      ["example.com"] = {"localhost", 5000};
      ["jabber.org"] = {"localhost", 5001};
    };

The format for individual items is
`["remote-hostname"] = {"srv-hostname", srv-port};`.

The special remote hostname `"*"` can be used as a wildcard:

        srvinjection = { ["*"] = {"xmpp-server.l.google.com", 5269} } -- Use Google's XMPP server for all hostnames

Reloading
=========

The module can be reloaded via the telnet console. Edit the config file
to make any updates.

You can reload the configuration from disk:

    config:reload()

And then reload the module to apply the configuration changes:

    module:reload("srvinjection", "*")

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

  ----- -------
  0.8   Works
  0.7   Works
  0.6   Works
  ----- -------

How it works
============

The module replaces the `lookup` function of the `net.adns` module with
its own. The original is set back when the module is unloaded.
