The python module is part of the module logic in unbound (together with<br>
the validator and iterator modules for example) and by default the<br>
operate() function is supposed to be called when it is the module's time<br>
of execution.<br>
The modules start after unbound couldn't answer with local data or from<br>
cache.<br>
<br>
However since version 1.6.0 there is the possibility to register inplace<br>
callback functions that will be called just before:<br>
- replying with local data or Chaos (CH),<br>
- replying from cache,<br>
- replying with SERVFAIL,<br>
- replying with a resolved query.<br>
<br>
Since version 1.8.0 the client's IP address is also available when<br>
replying with local data and from cache.<br>
<br>
You can register inplace callback functions during your module's (either<br>
C or Python) initialization.<br>

<br>
We changed our website's design and unfortunately we didn't have time to<br>
incorporate sphinx's output to the new design yet.<br>
<br>
For now you can build the Python module documentation from source by<br>
compiling '--with-pythonmodule' (which I think you already do), making<br>
sure that you have sphinx installed and running<br>
make doc<br>
<br>
The documentation will be generated in doc/html/pythonmod.<br>
You could take a look at the example named 'Inplace callbacks'.<br>
<br>
I hope that helps,<br>
