Tracing V2: readback protobuf and produce JSON compatible with Tracing V1 |
|||
Issue descriptionBackground context: bit.ly/TracingV2 The purpose of this is to be able to generate JSON from the protobuf which is backwards compatible with Tracing V1. This is for the transition period, before the tracing consumer (TraceViewer, DevTools, etc) can consume directly protos.
