Another week is has passed and the first evaluation phase slowly approaches. While I already fulfilled my goals (Jingle File Transfer using InBandBytestreams and SOCKS5Bytestreams), I still have a lot of work to do. The first working implementation I did is only so much – working. Barely. Now its time to learn from mistakes I made while I constructed my prototype and find better ways to do it in the next iteration. This is what I was up to in the past week and what will keep me from my usual sleep cycle for the coming week(s).

I spent the past week doing ground work and writing utility classes which will later allow me to send jingle actions in a clean way. The prototype implementation had all constructions of Jingle elements inside of the control flow, which made reading the code very hard. This will change in the next iteration.

While I worked on my implementation(s), I detected some errors in the XEPs involved and created pull requests against the xsf/xeps repository. In other spots I found some unclarities, but unfortunately my questions on the xsf chat were left unanswered. In some cases I found the solution myselves though.

Also I began upstreaming some changes and additions to the Smack repository. Parsers and elements of IBB have already been merged, as well as some more additions to the HashManager (XEP-0300) I created earlier, and some tests and fixes for the existing Jingle framework. Still open are my PR for SOCKS5 parsers and the first parts of the Jingle file transfer package.

I also dedicated a tiny little bit of my spare time to a non-GSoC project around a blog post on how to create an OMEMO capable chat client using Smack in less than 200 lines of code. The source code of the example application can be found in the FSFE’s brand new git repository. Unfortunately I also found a small bug in my OMEMO code that I have to fix sometime in the next weeks (nothing crucial, just some annoying faulty behavior).

I plan to spend the coming week working on my Jingle code, so that I have a mostly working framework when the evaluation phase begins.

Thats all for now. Happy Hacking 🙂
