cmd/trace: trace shows blank page on chrome

[tarekbadrsh]

Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

1.10

Does this issue reproduce with the latest release?

no

What operating system and processor architecture are you using (go env)?

ubuntu / amd64

What did you do?

run 'go tool trace m.trace'

What did you expect to see?

full view on the browser of trace

What did you see instead?

empty page on google chrome and firefox and got this error in the console Uncaught ReferenceError: tr is not defined

[AlekSi]

This error typically comes from the incompatible browser; only Chrome is supported. Can you confirm this issue with the latest stable version of Chrome? What version do you use?

[ALTree]

The fact that firefox doesn't work is explicitly documented:

Note that while the various profiles available when launching 'go tool
trace' work on every browser, the trace viewer itself (the 'view trace'
page) comes from the Chrome/Chromium project and is only actively tested on
that browser.

Chrome, on the other hand, should work.

[AlekSi]

We could check if tracing tool is available in the browser, and give an explicit error message to the user if it is not. That blank page was very confusing for me too the first time I tried to use it.

my chrome version
Version 66.0.3359.139 (Official Build) (64-bit)

It works for me. Can you please provide a small self-contained example demonstrating the problem?

[ALTree]

Are you sure the m.trace file is not empty? Can you attach it?

[tarekbadrsh]

i recently run a windows 10 vm and setup golang,google chrome and the file works well ,
it can help me for now , but i need it to run on my ubuntu machine

@tarekbadrshalaan
Can you check if trace_viewer_lean.html is available from your $GOROOT/misc/trace directory?

$ ls go env GOROOT/misc/trace

[tarekbadrsh]

@hyangah
i have no directory $GOROOT/misc/trace
and no directory $GOROOT/misc

[ALTree]

@tarekbadrshalaan I don't see how that's possible... please post here the output of go env.

What does ls /usr/lib/go-1.10 print?

Did you install Go from your OS package manager?
