tarekbadrsh · 2018-04-28T17:51:16Z

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

The text was updated successfully, but these errors were encountered:

AlekSi · 2018-04-29T08:33:41Z

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 · 2018-04-29T08:54:43Z

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 · 2018-04-29T08:59:04Z

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.

tarekbadrsh · 2018-04-29T11:44:01Z

my chrome version
Version 66.0.3359.139 (Official Build) (64-bit)
it's the latest

AlekSi · 2018-04-29T11:53:43Z

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

ALTree · 2018-04-29T12:01:30Z

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

tarekbadrsh · 2018-04-29T13:06:20Z

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 · 2018-05-02T07:24:05Z

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

ALTree · 2018-05-02T07:52:42Z

@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?

Please try installing the official distribution per the instructions at https://golang.org/doc/install and see if you can still reproduce the problem.

tarekbadrsh · 2018-05-04T07:14:37Z

ok it's working now with go installation from the official distribution on ubuntu/chrome

#34374

kjelle · 2020-02-21T08:01:30Z

Hello. I also got this problem.

What version of Go are you using (go version)?
1.13.6 (dnf install golang)

$ dnf info golang
Last metadata expiration check: 1:54:47 ago on Fri 21 Feb 2020 06:41:40 AM CET.

Name         : golang
Version      : 1.13.6
Release      : 1.fc31

Summary      : The Go Programming Language
URL          : http://golang.org/

Description  : The Go Programming Language.

Does this issue reproduce with the latest release?
yes (from fedora repos that is)

What operating system and processor architecture are you using (go env)?
linux / amd64 (fedora 31)

What did you do?
run a unittest writing trace to file, then running go tool trace trace.out and firefox automatically opens. I clicked on "View Trace".

What did you expect to see?
the contents of "view trace" for my unittest.

What did you see instead?
nothing, an empty, white page in firefox (Mozilla Firefox 71.0)
In the firefox console I get:

ReferenceError: tr is not definedtrace:59:5
    onResult http://127.0.0.1:33971/trace:59
    onreadystatechange http://127.0.0.1:33971/trace:43

It seems I am also missing the misc folder:

$ go env GOROOT
/usr/lib/golang

$ stat /usr/lib/golang/misc
stat: cannot stat '/usr/lib/golang/misc': No such file or directory

I removed the golang package dnf remove -y golang and installed it from https://golang.org/doc/install using go1.13.8.linux-amd64.tar.gz. Now I have the misc folder:

$ go env GOROOT  
/usr/local/go

$ stat `go env GOROOT`/misc
  File: /usr/local/go/misc
...

However, this doesn't fix the problem with an empty page in Firefox. When I launch the trace I get the same empty page with the same error message in the console. I see from #34374 and @hyangah in #34374 (comment) that it is not yet fixed in any stable download.

Updated
The workaround from @jpvillaseca in #34374 (comment) works on my go1.13.8 manual install.

Thank you very much.
I tried gotip on Macos and Centos. gotip works on Macos, but failed on Centos when I called gotip download.

It complains:

Updating the go development tree...
HEAD is now at 26154f3... cmd/compile: use NEG/NEGW pseudo-instructions on riscv64
error: unknown switch `i'
usage: git clean [-d] [-f] [-n] [-q] [-e ] [-x | -X] [--] ...

-f, --force force
-d remove whole directories
-e, --exclude

-x remove ignored files, too
-X remove only ignored files

gotip: failed to cleanup git repository: exit status 129

Do you hava any suggestion?

Do you have any solution about how to fix this?

hyangah · 2020-03-16T14:04:38Z

Please file a separate bug to track the gotip issue. cc @FiloSottile

If gotip doesn't work, an alternative is to build from the source. The instruction is https://golang.org/doc/install/source

I think the minor version release will be available soon and include the fix. But I don't know the concrete timeline yet cc @andybons

yangeagle · 2020-07-12T02:19:43Z

It is OK on Macos:
go 1.14.4
firefox 77.0.1 (64 bit)
