From: Hana (Hyang-Ah) Kim Date: Wed, 19 Feb 2020 03:41:20 +0000 (-0500) Subject: [release-branch.go1.14] cmd/trace: update to use WebComponents V0 polyfill X-Git-Tag: go1.14.1~13 X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=e6036e7da5292ce3b6c308499564046ce2c2d3e2;p=gostls13.git [release-branch.go1.14] cmd/trace: update to use WebComponents V0 polyfill Old trace viewer stopped working with Chrome M80+ because the old trace viewer heavily depended on WebComponents V0 which are deprecated. Trace viewer recently migrated to use WebComponents V0 polyfill (crbug.com/1036492). This CL brings in the newly updated trace_viewer_full.html (sync'd @ 9508452e) and updates the javascript snippet included in the /trace endpoint to use the polyfill. This brings in webcomponents.min.js copied from https://chromium.googlesource.com/catapult/+/9508452e18f130c98499cb4c4f1e1efaedee8962/third_party/polymer/components/webcomponentsjs/webcomponents.min.js That is necessary because the /trace endpoint needs to import the vulcanized trace_viewer_full.html. It's possible that some features are not working correctly with this polyfill. In that case, report the issue to crbug.com/1036492. There will be a warning message in the UI (yellow banner above the timeline) which can be hidden by clicking the 'hide' button. This allows to render the trace in browsers other than chrome in theory, but I observed some buttons and functions still don't work outside chrome. Updates #34374. Fixes #37343.
