imports: don't eagerly guess package names

Before this change, we guessed package names during loadPackageNames
when necessary. That made it impossible to tell if we failed to load
a package's name, e.g. because its source code is unavailable. That
interferes with fixes for golang/go#29557. It also meant that each
implementation of package name loading needs to do the guessing,
which gets annoying in CL 158097.

Instead, leave package names unset unless we're certain about them, and
guess only in (*pass).importIdentifier when necessary.

Refactoring only; no user-visible changes intended.

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.

Report Issues / Send Patches
