Redesign fixImports to have a clearer workflow, and hopefully create clear places to plug in go/packages. This change is mostly performance/functionality neutral, but does clean up some corner cases. The new flow centers around the pass type, which encapsulates the process of loading information about the current code, adding possible new imports, and trying to apply them. I'm hoping that it's easy to understand what's happening just by reading fixImports, and that new sources of information (e.g. a network service) fit well into that flow. Where possible, I left the functions near where they were extracted in hopes of making review easier, but it's probably not going to be easy. Sorry. I might move them into a more reasonable order in a followup CL. Notable modifications: - The stdlib cache is restructured to match pass' internal storage. - Sibling imports with conflicting names are considered. - Package name lookups are batched, hopefully making it easier to plug in go/packages. Questions that might be worth answering: - Should findImportGoPath really scan $GOROOT? Unless the user is working on a development copy, it's totally redundant with the cache. - What is the best way to combine candidates from multiple sources? Right now the first one wins, and findStdlibCandidates relies on that to get crypto/rand ahead of math/rand. - In the third pass, should it assume sibling imports or should it actually go load the exports? It didn't load them before, but that seems arbitrary.

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.
