mod_smacks: Send out more ack requests where needed Under some circumstances it was possible that more than "max_unacked_stanzas" where left in the outgoing stanza queue without forcing an ack. This could happen, when more stanzas entered the queue while the last ack request was still unanswered. Now the test "#queue > max_unacked_stanzas" is done upon receiving an ack as well as when sending out stanzas, which fixes this bug.

summary: JSON Encodings for XMPP
...

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

This plugin encodes XMPP as JSON. This is an implementation of
[XEP-0295: JSON Encodings for
XMPP](http://xmpp.org/extensions/xep-0295.html).

Simply loading this module makes Prosody accept JSON on C2S streams
(legacy XML clients are still supported).

For BOSH, it requires mod\_bosh be loaded, and JSON should be directed
at the `/jsonstreams` HTTP path.

JSON for S2S isn't supported due to the lack of a discovery mechanism,
so we have left that disabled to stay compatible with legacy XML
servers.

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

Just add `"json_streams"` in your config's global `modules_enabled`
list, for example:

    modules_enabled = {
        ...
        "json_streams";
    }

Strophe.js plugin
=================

We also developed a [JSON streams
plugin](http://prosody-modules.googlecode.com/hg/mod_json_streams/strophe.jsonstreams.js)
for the popular [strophe.js](http://code.stanziq.com/strophe) library.

Just include it like this after including the strophe library, and your
strophe-based client will be speaking JSON:

    <script type="text/javascript" src="strophe.jsonstreams.js"></script>

Be sure to set the HTTP path to `/jsonstreams`. No other changes are
required.
