Forbid modifying tracing state from worker threads, either through the built-in module or inspector sessions, since the main thread owns all global state, and at least the `async_hooks` integration is definitely not thread safe in its current state.

This is useful primarily as a quick check to see if rejections may be going unhandled (and unnoticed in a process).

Add basic trace events for node_contextify. These generally align very well with V8.ScriptCompile and V8.ScriptExecute trace events and provide good additional context. For instance, using the node.vm.script trace category at startup allows us to see exactly how long compilation and init of each of our core modules adds to the startup time.

2018-04-17trace_events: adds a new trace_events apiJames M Snell
Removes the requirement to use `--trace-events-enabled` to enable trace events. Tracing is enabled automatically if there are any enabled categories. Adds a new `trace_events` module with an API for enabling/disabling trace events at runtime without a command line flag. ```js const trace_events = require('trace_events'); const categories = [ 'node.perf', 'node.async_hooks' ]; const tracing = trace_events.createTracing({ categories }); tracing.enable(); // do stuff tracing.disable(); ``` Multiple `Tracing` objects may exist and be enabled at any point in time. The enabled trace event categories is the union of all enabled `Tracing` objects and the `--trace-event-categories` flag.

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.
