## Resources for Go's trace viewer

Go execution trace UI (`go tool trace`) embeds
Chrome's trace viewer (Catapult) following the
[instructions](
https://chromium.googlesource.com/catapult/+/refs/heads/master/tracing/docs/embedding-trace-viewer.md). This directory contains
the helper files to embed Chrome's trace viewer.

The current resources were generated/copied from
[`Catapult@9508452e18f130c98499cb4c4f1e1efaedee8962`](
https://chromium.googlesource.com/catapult/+/9508452e18f130c98499cb4c4f1e1efaedee8962).

### Updating `trace_viewer_full.html`

The file was generated by catapult's `vulcanize_trace_viewer` command.

```
$ git clone https://chromium.googlesource.com/catapult
$ cd catapult
$ ./tracing/bin/vulcanize_trace_viewer --config=full
$ cp tracing/bin/trace_viewer_full.html $GOROOT/src/cmd/trace/static/trace_viewer_full.html
```

We are supposed to use --config=lean (produces smaller html),
but it is broken at the moment:
https://github.com/catapult-project/catapult/issues/2247

### Updating `webcomponents.min.js`

`webcomponents.min.js` is necessary to let the trace viewer page
to import the `trace_viewer_full.html`.
This is copied from the catapult repo.

```
$ cp third_party/polymer/components/webcomponentsjs/webcomponents.min.js $GOROOT/src/cmd/trace/static/webcomponents.min.js
```
