perf_hooks,trace_events: use stricter equality

2019-06-16T08:45:15+00:00

There is no need to use loose equality on these checks because
undefined is caught by the preceding typeof check.

src: split ownsProcessState off isMainThread

2019-02-05T20:55:54+00:00

Embedders may want to control whether a Node.js instance
controls the current process, similar to what we currently
have with `Worker`s.

Previously, the `isMainThread` flag had a bit of a double usage,
both for indicating whether we are (not) running a Worker and
whether we can modify per-process state.

trace_events: forbid tracing modifications from worker threads

2018-10-24T14:20:35+00:00

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.

bootstrapper: move internalBinding to NativeModule

internalBinding is used so often that it should just automatically be
available for usage in internals.

trace_events: adds a new trace_events api

2018-04-17T15:30:20+00:00

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.
