## 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 ``` ## Licenses The license for trace-viewer is as follows: // Copyright (c) 2012 The Chromium Authors.
