2019-07-21src: expose TraceEventHelper with NODE_EXTERNSamuel Attard
As node requires a tracing controller to be initialized embedders need access to the TraceEventHelper so that we can actually set the tracing controller.

Metadata trace-events should be held in secondary storage so that they can be periodically reemitted. This change establishes the secondary storage and ensures that events are reemitted on each flush.

2017-08-17src: Node implementation of v8::PlatformMatt Loring
Node.js currently uses the V8 implementation of the DefaultPlatform which schedules VM tasks on a V8 managed thread pool. Since the Node.js event loop is not aware of these tasks, the Node.js process may exit while there are outstanding VM tasks. This will become problematic once asynchronous wasm compilation lands in V8. This PR introduces a Node.js specific implementation of the v8::Platform on top of libuv so that the event loop is aware of outstanding VM tasks.

2017-08-17tracing: Update to use new Platform tracing apisMatt Loring
V8 modified the platform API to accept a tracing controller at platform creation time that is required to be present for the lifetime of the platform if tracing will every be enabled. This will simplify the implementation of a v8::Platform subclass for node.

2017-04-05src: Update trace event macros to V8 5.7 versionMatt Loring
src/tracing/trace_event.h was updated by applying the following changes: 1) Include src/tracing/trace_event_common.h instead of the one from v8 base. 2) Replace all instances of base::Atomic with intptr_t (trace events can only be generated from the main thread for now). 3) Replace instances of V8_INLINE with inline. 4) Eliminate uses of DCHECK. 5) Eliminate uses of V8_UNLIKELY, the branch predictor should be good enough alone. 6) Change the namespace used by trace_event.h from v8::internal::tracing to node::tracing. 7) Remove CallStatsScopedTracer class and related macros (they rely on V8 implementation details). 8) Change ConvertableToTraceFormat to v8::ConvertableToTraceFormat. 9) Add function "static void SetCurrentPlatform(v8::Platform* platform);" to the declaration of TraceEventHelper.

2016-12-20src: Node Tracing Controllermisterpoe
This commit adds support for trace-event tracing to Node.js. It provides a mechanism to centralize tracing information generated by V8, Node core, and userspace code. It includes: - A trace writer responsible for serializing traces and cycling the output files so that no individual file becomes to large. - A buffer for aggregating traces to allow for batched flushes. - An agent which initializes the tracing controller and ensures that trace serialization is done on a separate thread. - A set of macros for generating trace events. - Tests and documentation.
