<p>Hope everyone had a great year. Let's take a look at what happened and what's coming.</p>
<p>2019 has been the year of pre-releases with Ranch 2.0 and Gun 2.0 getting close to completion. I hope both of them will be out in the first half of 2020. They were supposed to be released in 2019, but I guess that was a bit optimistic. Ranch 2.0 is a big performance improvement if you need to quickly open a large amount of connections (but you probably don't), while Gun 2.0 is a few small breaking changes in the lower level interface to make things clearer, plus a ton of new features.</p>
<p>Cowboy 2.7 has been released and 2.8 is just around the corner. 2.8 will improve the performance and include a section in the guide to get the most performance for HTTP/1.1 applications, since it is currently not obvious. There might be further experiments around asynchronous interfaces in order to squeeze the most performance out of Cowboy 2.</p>
<p>At the start of 2019 I submitted a patch to Erlang/OTP that added support for <code>active,N</code> to the ssl application. This is available since OTP 21.3 and is the basis behind the biggest performance improvement in upcoming Cowboy 2.8.</p>
<p>Last year I was hoping to keep the number of tickets open across all my projects to below 100. I did not quite accomplish this but have managed to keep them at around 120. Not too bad considering many of those are just ideas or personal reminders.</p>
<p>I've recently resumed work on my Farwest project. This is a complete reboot following the initial experiments and a few years of research. The goal is to provide a framework for building fully RESTful applications, including both server and client components. An <a href="https://github.com/ninenines/farwest_demo">early demo</a> is already available. The <a href="https://github.com/ninenines/farwest">project itself</a> is also available, though that is a very early version. I will be giving a demo of the project at <a href="https://fosdem.org/2020/">FOSDEM 2020</a> in the <a href="https://beam-fosdem.org/">BEAM Fosdem Devroom</a> in just about one month. It's free, you should come!</p>
<p>The demo will take around 20 minutes and I will do some live coding, creating an API for manipulating (d)ets tables. 20 minutes is a short time so we'll see how far I'll manage to get. I can promise that discovery will be working, at the very least.</p>
<p>Related to Farwest, I've recently submitted a patch to Erlang/OTP adding the functions <code>uri_string:resolve/2,3</code> to perform <a href="https://tools.ietf.org/html/rfc3986#section-5">reference resolution</a>. This was necessary in order to implement <a href="https://tools.ietf.org/html/rfc8288">the Link header</a> in Cowlib. I have also implemented <a href="https://tools.ietf.org/html/draft-ietf-httpbis-header-structure-14">Structured Headers</a>, <a href="https://tools.ietf.org/html/draft-ietf-httpbis-variants-06">Variants</a> and <a href="https://tools.ietf.org/html/rfc6570">URI Templates</a>. The combination of these enable efficient resource discovery in Farwest.</p>
<p>In the context of my work with the team at RabbitMQ I have submitted patches to Erlang/OTP to add the functions <code>crypto:cipher_info/1</code> and <code>crypto:hash_info/1</code>. We have also submitted smaller patches to expose more metrics related to the Erlang distribution, helped fix a few issues around the interface for custom distribution drivers, and submitted a number of improvements to <a href="https://github.com/deadtrickster/prometheus.erl">prometheus.erl</a> including some new collectors and dashboards.</p>
<p>You can forward Santa Claus to <a href="https://github.com/sponsors/essen">GitHub Sponsors</a> for sending presents. I use these funds mainly for improving the testing environments for my projects.</p>
<p>Have great holidays, Merry Christmas, Happy New Year, and see you next year!</p>
