Runtime documentation

  • Error handling — global error/unhandledrejection events, reportError, catching Java exceptions in JS (error.nativeException), forwarding JS throws to Java callers (interop.escapeException), JS stacks on Java exceptions (com.tns.JavaScriptStackTrace), configuration flags, and crash-reporter integration.
  • structuredClone — the WHATWG structuredClone(value, { transfer }) global: what clones, how graph identity and cycles are preserved, ArrayBuffer transfer, and the DataCloneError-named Error that stands in for DOMException.
  • Implementing additional Chrome DevTools protocol Domains

Knowledge

Notes on work that is done, kept because the reasoning is expensive to reconstruct rather than because anything needs doing.

  • V8 10.3 → 14.9 migration — the API changes and their site counts, why each non-default gn arg exists, the accessor rules that are not mechanical, and the traps that only show up at runtime.
