Types

type Invocation

type Invocation struct {
	Verb       string
	Args       []string
	BuildFlags []string
	Env        []string
	WorkingDir string
	Logf       func(format string, args ...interface{})
}

An Invocation represents a call to the go command.

func (*Invocation) RunPiped

func (i *Invocation) RunPiped(ctx context.Context, stdout, stderr io.Writer) error

RunPiped is like Run, but relies on the given stdout/stderr

type Runner

type Runner struct {
	// contains filtered or unexported fields
}

An Runner will run go command invocations and serialize them if it sees a concurrency error.

func (*Runner) Run

func (runner *Runner) Run(ctx context.Context, inv Invocation) (*bytes.Buffer, error)

Run calls Runner.RunRaw, serializing requests if they fight over go.mod changes.

func (*Runner) RunRaw

func (runner *Runner) RunRaw(ctx context.Context, inv Invocation) (*bytes.Buffer, *bytes.Buffer, error, error)

RunRaw calls Invocation.runRaw, serializing requests if they fight over go.mod changes.
