How we completely rewrote our static code analyzer for Kotlin
summary
A full rewrite replaces the universal intermediate tree with SonarKotlin 2.0 built on PSI and a semantic model, raising rule precision and expanding to about ~120 rules but also tripling reported issues on sample projects and causing slow analysis and occasional OOMs. The talk covers concrete fixes: companion object and delegate import handling, operator mapping, and a pragmatic heuristic comment-detection to avoid compiling every comment. Watch for hard performance tradeoffs, exact bugs found, and which fixes actually land.
