Rebecca Stambler 593de60622 go/packages: handle an overlay edge case with test variants
As usual, in debugging the creation of a new file with gopls, I've
encountered a go/packages overlay bug. The issue is:

A file b/b.go with package name "b" exists on disk. A package
b/b_test.go with no content exists on disk. There is an overlay for
b/b_test.go that contains the package name "b". Running packages.Load
for file=b/b_test.go will result in a failure to load package b
[b.test]. This change adds this test to the go/packages tests.

This case is fixed by restricting the fallback logic in
runContainsQueries. We only attempt to construct an ad-hoc package if
the original package was returned with no GoFiles.

Also, a minor change to the gopls error parsing code that fixes a case
in which diagnostics were being sent without corresponding files.

Updates golang/go#36635.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
