go/packages: Fixes for bad wd handling

Darwin convertes the working directory to a real path which affects the
path a command is started with when you exec.
This causes a problem where the path the go list command is run with
does not match the path the outside program is trying to use, which
causes both undesirably changed paths in it's outputs, and sometimes
failures to cope with modules when source files are "outside" the module
root.
The go standard library has a special feature in os.Getwd where it
checks if the PWD environment variable is the same inode as the system
cwd, and if it is it returns the PWD instead. This change deliberately
sets the PWD before running go list so that behaviour is triggered,
which fixes all the paths.
This was breaking the mac build bots in a goimports test, it should be
fixed now.

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

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with “x/tools/(your subdir):” in the subject line, so it is easy to find.
