1## Resources for Go's trace viewer
2
3Go execution trace UI (`go tool trace`) embeds
4Chrome's trace viewer (Catapult) following the
5[instructions](
6https://chromium.googlesource.com/catapult/+/refs/heads/master/tracing/docs/embedding-trace-viewer.md). This directory contains
7the helper files to embed Chrome's trace viewer.
8
9The current resources were generated/copied from
10[`Catapult@9508452e18f130c98499cb4c4f1e1efaedee8962`](
11https://chromium.googlesource.com/catapult/+/9508452e18f130c98499cb4c4f1e1efaedee8962).

13### Updating `trace_viewer_full.html`
14
15The file was generated by catapult's `vulcanize_trace_viewer` command.
16
17```
18$ git clone https://chromium.googlesource.com/catapult
19$ cd catapult
20$ ./tracing/bin/vulcanize_trace_viewer --config=full
21$ cp tracing/bin/trace_viewer_full.html $GOROOT/src/cmd/trace/static/trace_viewer_full.html
22```
23
24We are supposed to use --config=lean (produces smaller html),
25but it is broken at the moment:
26https://github.com/catapult-project/catapult/issues/2247
27
28### Updating `webcomponents.min.js`
29
30`webcomponents.min.js` is necessary to let the trace viewer page
31to import the `trace_viewer_full.html`.
32This is copied from the catapult repo.
33
34```
35$ cp third_party/polymer/components/webcomponentsjs/webcomponents.min.js $GOROOT/src/cmd/trace/static/webcomponents.min.js
36```
