DefaultTracer provides a tracer that updates the CI_ enviornment variables to include the correct timestamp and status. TODO(bradrydzewski) find either a new home or better name for this.

Functions

func Parse

func Parse(r io.Reader) (*backend.Config, error)

Parse parses the pipeline config from an io.Reader.

func ParseFile

func ParseFile(path string) (*backend.Config, error)

ParseFile parses the pipeline config from a file.

func ParseString

func ParseString(s string) (*backend.Config, error)

ParseString parses the pipeline config from a string.

Types

type ExitError

type ExitError struct {
	Name string
	Code int
}

An ExitError reports an unsuccessful exit.

func (*ExitError) Error

func (e *ExitError) Error() string

Error returns the error message in string format.

type LogFunc

type LogFunc func(*backend.Step, multipart.Reader) error

LogFunc type is an adapter to allow the use of an ordinary function for process logging.

func (LogFunc) Log

func (f LogFunc) Log(step *backend.Step, r multipart.Reader) error

Log calls f(proc, r).

type Logger

type Logger interface {
	Log(*backend.Step, multipart.Reader) error
}

Logger handles the process logging.

type OomError

type OomError struct {
	Name string
	Code int
}

An OomError reports the process received an OOMKill from the kernel.

func (*OomError) Error

func (e *OomError) Error() string

Error reteurns the error message in string format.

type Option

type Option func(*Runtime)

Option configures a runtime option.

func WithContext

func WithContext(ctx context.Context) Option

WithContext returns an option configured with a context.

func WithEngine

func WithEngine(engine backend.Engine) Option

WithEngine returns an option configured with a runtime engine.

func WithLogger

func WithLogger(logger Logger) Option

WithLogger returns an option configured with a runtime logger.

func WithTracer

func WithTracer(tracer Tracer) Option

WithTracer returns an option configured with a runtime tracer.

type Runtime

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

Runtime is a configuration runtime.

func New

func New(spec *backend.Config, opts ...Option) *Runtime

New returns a new runtime using the specified runtime configuration and runtime engine.

func (*Runtime) Run

func (r *Runtime) Run() error

Run starts the runtime and waits for it to complete.

type State

type State struct {
	// Global state of the pipeline.
	Pipeline struct {
		// Pipeline time started
		Time int64 `json:"time"`
		// Current pipeline step
		Step *backend.Step `json:"step"`
		// Current pipeline error state
		Error error `json:"error"`
	}

	// Current process state.
	Process *backend.State
}

State defines the pipeline and process state.

type TraceFunc

type TraceFunc func(*State) error

TraceFunc type is an adapter to allow the use of ordinary functions as a Tracer.

func (TraceFunc) Trace

func (f TraceFunc) Trace(state *State) error

Trace calls f(proc, state).

type Tracer

type Tracer interface {
	Trace(*State) error
}

Tracer handles process tracing.
