Comment 1:

in general, cmd/go and godoc both can't handle symlinks well.
avoid using symlinks if you can.

_Labels changed: added repo-tools, release-none._

This is important to me. I already have a place in my filesystem where I do checkouts of things I'm working on, and I'd like to do the following:
mkdir ${GOPATH}/src/myserver.tld
cd ${GOPATH}/src/myserver.tld
ln -s ${HOME}/my/usual/path/to/my/project .

I'd like to then see the documentation for the thing I'm working on in my godoc server.
I have a fix written for this, it's a small change to golang.org/x/tools/godoc/dirtrees.go

The above symlink already works for building! I can use this just fine as
import "myserver.tld/project"

Given that, it's incongruous that godoc doesn't _also_ work.

If you use gvm linkthis, also have the issue.
