Resources for Go's trace viewer

Go execution trace UI (go tool trace) embeds Chrome's trace viewer (Catapult) following the instructions. This directory contains the helper files to embed Chrome's trace viewer.

The current resources were generated/copied from 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/misc/trace/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/misc/trace/webcomponents.min.js
