<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I added an example in the file comment in json.h in trunk to better explain how to handle ast_json references properly. Hope that helps!</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I notice these reviews are against revision 1. The code here has changed a bit, but it's worth noting that there isn't any need to bump the reference to the json_temp here since if it succeeds, we immediately set json_temp to be a new json object and if it fails we break out of the function entirely.
I do notice now though that if it fails, when the function exits it will try to unref json_temp which will at this point be a stale pointer... that's no good. I'll fix it by setting json_temp to NULL here.</pre>

In order to convert this set of messages I had to change all of the event blob stuff into JSON strings inside of a JSON blob loaded onto a JSON payload and sent out over stasis to the security topic where it is then consumed by stasis and read into a log message in the appropriate fashion with the fields in the right order to catch the bird to catch the spider to catch the fly.</pre>
