James M Snell 5c27e44488 trace_events: adds a new trace_events api ... 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.
