sbt and the miners of the wild west

small village of sbt

I’m a volunteer maintainer/core dev of sbt and Zinc, the toolchain that powers the Scala programming language, which is a multi-paradigm language targetting JVM, JS, and native. Scala itself has been around for 20 years, and since Twitter’s adoption in 2009 it’s been used by Apache Spark, LinkedIn, Morgan Stanley, ING, Airbnb, Spotify, Netflix, etc.

Despite Scala’s accolades over the years, both sbt and Zinc remain niche projects, maintained mostly by me with the collaboration with Scala Center, and contributions by a small circle of Scala users and tooling folks from EPFL, Lightbend/Akka, JetBrains, VirtusLab, Databricks, and Gradle many of whom I’ve met in Poland or Switzerland.

sudori part 8: no-op compilation performance

This is a blog post on sbt 2.x development, continuing from sbt 2.x remote cache, sudori part 4, part 5 etc. I work on sbt 2.x in my own time with collaboration with the Scala Center and other volunteers, like Billy at EngFlow. In this post, I want to highlight the perf improvement work I attempted in sbt 2.0.0-RC7, which was released yesterday.

no-op performance regression

Besides jump starting the plugin ecosystem, one of the motivations for the having release candidates of sbt 2.x is to start testing them with actual builds. As they say, everybody has an operational plan until they get punched in the mouth.

incremental compilation of Scala 3

In this post, I want to look into the incremental compilation of Scala 3, or the apparent problem associated with it. The incremental compilation on Scala 2.12 or 2.13 has been fairly stable, but for some reason it’s more fragile on Scala 3.x in my experience. We will investigate the cause and attempt to fix it as scala/scala3#24171.
