示例1: getWorkFromSpec
// getWorkFromSpec forcibly retrieves a work unit from a work spec.
// It could create a work unit if spec is a continuous spec with no
// available units. It ignores other constraints, such as whether the
// work spec is paused.
func (w *worker) getWorkFromSpec(spec *workSpec, meta *coordinate.WorkSpecMeta) *attempt {
var unit *workUnit
now := w.Coordinate().clock.Now()
if len(spec.available) != 0 {
unit = spec.available.Next()
} else if meta.CanStartContinuous(now) {
// Make a brand new work unit. Its key is the string
// form of a time_t.
seconds := now.Unix()
nano := now.Nanosecond()
milli := nano / 1000000
name := fmt.Sprintf("%d.%03d", seconds, milli)
var exists bool
unit, exists = spec.workUnits[name]

name: name,
