perf_hooks: add HttpRequest statistics monitoring #28445

2019-07-11T22:36:27+00:00

```js
const { PerformanceObserver, performance } = require('perf_hooks');
const http = require('http');

const obs = new PerformanceObserver((items) => {
  const entry = items.getEntries()[0];
  console.log(entry.name, entry.duration);
});
obs.observe({ entryTypes: ['http'] });

const server = http.Server(function(req, res) {
  server.close();
  res.writeHead(200);
  res.end('hello world\n');
});

server.listen(0, function() {
  const req = http.request({
    port: this.address().port,
    path: '/',
    method: 'POST'
  }).end();
});
```

src: use predefined AliasedBuffer types in the code base

2019-04-26T06:23:31+00:00

Instead of allowing the callers to instantiate the template
with any numeric types (such as aliasing a Uint8Array to double[]),
predefine types that make sense and use those instead.

src: unify uptime base used across the code base

2019-02-18T09:58:22+00:00

This patch joins `per_process::prog_start_time` (a double)
and `performance::performance_node_start` (a uint64_t) into a
`per_process::node_start_time` (a uint64_t) which gets initialized
in `node::Start()`.

perf_hooks: make GC tracking state per-Environment

2018-12-17T01:29:10+00:00

Otherwise this is global state that may be subject to race
conditions e.g. when running `perf_hooks` inside of Worker threads.

Tracking the GC type is removed entirely since the variable was unused.

src: add missing `NODE_WANT_INTERNALS` guards

2018-08-28T14:54:07+00:00

We generally add these to all headers that are considered
internal to Node.

These aren’t distributed as part of the headers tarball,
so I think this does not have to be semver-major
(and we have been changing the APIs in these headers
freely anyway).
