/Users/herohde/go/src/ (skip: 2)
  • /Users/herohde/go/src/ (skip: 3) /usr/local/go/src/runtime/proc.go (skip: 4) // not always present /usr/local/go/src/runtime/asm_amd64.s (skip: 4 or 5)

func Execute

func Execute(ctx context.Context, p *pb.Pipeline, endpoint string, opt *JobOptions, async bool) (string, error)

Execute executes a pipeline on the universal runner serving the given endpoint. Convenience function.

func Prepare

func Prepare(ctx context.Context, client jobpb.JobServiceClient, p *pb.Pipeline, opt *JobOptions) (id, endpoint string, err error)

Prepare prepares a job to the given job service. It returns the preparation id and artifact staging endpoint, if successful.

func Stage

func Stage(ctx context.Context, id, endpoint, binary string, files ...artifact.KeyedFile) (string, error)

Stage stages the worker binary and any additional files to the given artifact staging endpoint. It returns the commit token if successful.

func Submit

func Submit(ctx context.Context, client jobpb.JobServiceClient, id, token string) (string, error)

Submit submits a job to the given job service. It returns a jobID, if successful.

func WaitForCompletion

func WaitForCompletion(ctx context.Context, client jobpb.JobServiceClient, jobID string) error

WaitForCompletion monitors the given job until completion. It logs any messages and state changes received.

	// Worker is the worker binary override.
	Worker string

	// InternalJavaRunner is the class of the receiving Java runner. To be removed.
