Title of the talk

cffi FTW - Bringing Wireshark's Dissectors to Python

Description

The talk is more about how to write Python extension modules using cffi using a motivating example and discusses practical aspects, gotchas and things to remember. I am submitting a proposal for the same for Pycon 2020 India.

I will be talking about lessons learnt while implementing wishpy. This is a WIP.

Table of Contents

Just copying from Pycon Proposal! :-)

1. Problem definition (2-3 mins)

2. Options for developing Python bindings (2-3 mins)

   • cffi
   • ctypes
   • SWIG
   • Cython
   • Classic Python API

3. CFFI deep(ish) dive (10-15 mins)

   • Working with cffi stages -
     • Development Stage
     • Build/Packaging Stage
     • Runtime Stage
   • Some not so FAQs.

4. Putting things together - (5 mins)

   • Really just a bunch of queues with Python processes/threads at the end :-)
   • Packet visualization

Duration (including Q&A)

Prerequisites

The talk might be slightly advanced level and might need some familiarity with building C projects etc (this is not a hard requirement, but will help certainly!)

Speaker Info

I have been active on and off in Python community in Pune. Thanks to other commitments don't get to attend PythonPune meetups as regularly as I'd like to, but after it's shifted to online format, I am trying to be better at at! (though did miss first couple of them)
