Web Engines Hackfest 2016

From September 26th to 28th we celebrated at the Igalia HQ the 2016 edition of the Web Engines Hackfest. This year we broke all records and got participants from the three main companies behind the three biggest open source web engines, say Mozilla, Google and Apple. Or course, it was not only them, we had some other companies and ourselves. I was active part of the organization and I think we not only did not get any complain but people were comfortable and happy around.

We had several talks (I included the slides and YouTube links):

We had lots and lots of interesting hacking and we also had several breakout sessions:

  • WebKitGTK+ / Epiphany
  • Servo
  • WPE / WebKit for Wayland
  • Layout Models (Grid, Flexbox)
  • WebRTC
  • JavaScript Engines
  • MathML
  • Graphics in WebKit

What I did during the hackfest was working with Enrique and Žan to advance on reviewing our downstream implementation of Media Source Extensions (MSE) in order to land it as soon as possible and I can proudly say that we did already (we didn’t finish at the hackfest but managed to do it after it). We broke the bots and pissed off Michael and Carlos but we managed to deactivate it by default and continue working on it upstream.

So summing up, from my point of view and it is not only because I was part of the organization at Igalia, based also in other people’s opinions, I think the hackfest was a success and I think we will continue as we were or maybe growing a bit (no spoilers!).

Finally I would like to thank our gold sponsors Collabora and Igalia and our silver sponsor Mozilla.

Web Engines Hackfest according to me

And once again, in December we celebrated the hackfest. This year happened between Dec 7-9 at the Igalia premises and the scope was much broader than WebKitGTK+, that’s why it was renamed as Web Engines Hackfest. We wanted to gather people working on all open source web engines and we succeeded as we had people working on WebKit, Chromium/Blink and Servo.

The edition before this I was working with Youenn Fablet (from Canon) on the Streams API implementation in WebKit and we spent our time on the same thing again. We have to say that things are much more mature now. During the hackfest we spent our time in fixing the JavaScriptCore built-ins inside WebCore and we advanced on the automatic importation of the specification web platform tests, which are based on our prior test implementation. Since now they are managed there, it does not make sense to maintain them inside WebKit too, we just import them. I must say that our implementation is fairly complete since we support the current version of the spec and have almost all tests passing, including ReadableStream, WritableStream and the built-in strategy classes. What is missing now is making Streams work together with other APIs, such as Media Source Extensions, Fetch or XMLHttpRequest.

There were some talks during the hackfest and we did not want to be less, so we had our own about Streams. You can enjoy it here:

You can see all hackfest talks in this YouTube playlist. The ones I liked most were the ones by Michael Catanzaro about HTTP security, which is always interesting given the current clumsy political movements against cryptography and the one by Dominik Röttsches about font rendering. It is really amazing what a browser has to do just to get some letters painted on the screen (and look good).

As usual, the environment was amazing and we had a great time, including the traditional Street Fighter‘s match, where Gustavo found a worthy challenger in Changseok 🙂

Of course, I would like to thank Collabora and Igalia for sponsoring the event!

And by the way, quite shortly after that, I became a WebKit reviewer!
