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

vgo version
go version go1.10.1 linux/amd64 vgo:2018-02-20.1

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

vgo env
GOARCH="amd64"
GOBIN=""
GOCACHE="/home/matthew/.cache/go-build"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/matthew/src/Go_external_1.10.1"
GOPROXY=""
GORACE=""
GOROOT="/home/matthew/src/golang/go1.10.1"
GOTMPDIR=""
GOTOOLDIR="/home/matthew/src/golang/go1.10.1/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build416094540=/tmp/go-build -gno-record-gcc-switches"
VGOMODROOT="/home/matthew/tmp/foo"

What did you do?

mkdir -p tmp/foo
cd !!$
echo 'module foo' > go.mod
vgo get goshawkdb.io/common

What did you expect to see?

vgo: finding goshawkdb.io/common v1.0.0

What did you see instead?

vgo get goshawkdb.io/common: unknown VCS, Repo: hg, https://src.goshawkdb.io/common

Now, this works fine with normal go get and the meta header is there correctly:

curl https://goshawkdb.io/common

<html>
<head>
<meta name="go-import" content="goshawkdb.io/common hg https://src.goshawkdb.io/common"/>
<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
</head>
</html>

I suspect this may be classed as a dupe of #25074 but that issue isn't enormously clear to me ;)

The other thing worth pointing out is that hgweb.cgi is probably the most common way of putting an http interface on hg repos. https://www.mercurial-scm.org/wiki/HgWebDirStepByStep an example of which is https://src.goshawkdb.io/common Note that this does provide tags (https://src.goshawkdb.io/common/tags and even rss: https://src.goshawkdb.io/common/rss-tags) and features such as tarballs of specific tags (eg https://src.goshawkdb.io/common/archive/goshawkdb_0.3.1.tar.gz) and even revisions (eg https://src.goshawkdb.io/common/archive/458b975cb054.tar.gz). Point is, you don't have to fall back to cloning the whole repo if you can detect that you're talking to hgweb.cgi

Yep, I think it is. Russ is working on a number of fixes to vgo get this week, so hopefully this will get better soon.
