Issue updating pkg.go.dev

[JeffG]

I have a custom url package nspeed.app/nspeed which redirects to github.com/nspeed-app/nspeed (using a meta tag go-import):

<meta name=go-import content="nspeed.app/nspeed git https://github.com/nspeed-app/nspeed>

It was setup a year ago or so with version v0.11.0 and was working fine.

Today I updated some code and the github repo tag to v0.12.0

waited a few days then

go get nspeed.app/nspeed@latest

but it still fetch the old version.

So I tried to force the update as specified here: https://pkg.go.dev/about#adding-a-package

to update from the pkg web site directly:

https://pkg.go.dev/nspeed.app/nsp...@v0.12.0

first I clicked the "request" button but later the page displays "not found"

then I tried with proxy and 'go get', I get the same error about xml:

curl https://proxy.golang.org/nspeed.app/nspeed/@v/v0.12.0.info

go: nspeed.app/nsp...@v0.12.0: unrecognized import path "nspeed.app/nspeed": parsing nspeed.app/nspeed: XML syntax error on line 1: expected /> in element

I am probably missing something or are go-import meta tags not working anymore may be?

update: I think I might I found the issue, the bot doesn't seems to follow redirections (at least 301 ones).

Thanks to the option "-x" of go get:

go get -x nspeed.app/nsp...@v0.12.0

leads to 

 https://nspeed.app/nspeed?go-get=1

which redirects '301) to the same url but with trailing slash:

 https://nspeed.app/nspeed/?go-get=1 

which has the go-import tag but the bot doesn't seem to follow the redirection.

Is this the expected behavior of the bot?

No, it;s a bug similar to https://github.com/prettier/prettier/issues/8210

`go` follows the redirects, but there are several elements in your
html that cause parsing issues (unquoted attribute values containing
`/`).

> <link rel=apple-touch-icon sizes=180x180 href=/apple-touch-icon.png>
> <link rel=icon type=image/png sizes=32x32 href=/favicon-32x32.png>

> <link rel=manifest href=/site.webmanifest>
> <link rel=mask-icon href=/safari-pinned-tab.svg color>
> <link rel="shortcut icon" href=/favicon.ico>

Much thanks for finding the issue !

The site is generated by Hugo, I'll try to fix the template.

Upon more investigation, the issue was already reported in 2020: https://github.com/golang/go/issues/39748 but never fixed

There is a workaround with Hugo to prevent minification from removing quotes.

Add this to hugo conf file:

minify:
  tdewolff:
    html:
      keepQuotes: true
