- Each isolate has its own TimelineEventBuffer - Each isolate has TimelineEventStreams for API, Compiler, Embedder, Isolate, and GC - Compiler, Isolate, Embedder, and GC are being inserted into the stream - Basic unit tests - Dart API for injecting timeline events - Arbitrary number of native and Dart arguments can be attached to each event - JSON printing - Output can be loaded by about://tracing - Add --timeline-trace-dir flag Short term follow up CLS: - Service protocol requests to enable / disable tracing and retrieve a trace - UI for Observatory - Dart code EventStreams and Events R=asiva@google.com Review URL: https://codereview.chromium.org//1170503004.
