For reasons of ease of76// implementation and lack of good evidence it's not required to let a not started iteration to77// finish in other words if you call start and then gracefulStop, there is no requirement for78// 1 iteration to have been started.79// - hardStop must stop an iteration in process80// - it's not required but preferable, if where possible to not reactivate VUs and to reuse context81// as this speed ups the execution82type vuHandle struct {83 mutex *sync.Mutex84 parentCtx context.Context85 getVU func() (lib.InitializedVU, error)86 returnVU func(lib.InitializedVU)87 nextIterationCounters func() (uint64, uint64)88 config *BaseConfig89 initVU lib.InitializedVU90 activeVU lib.ActiveVU91 canStartIter chan struct{}92 state stateType // see the table above for meanings93 // stateH []int32 // helper for debugging94 ctx context.Context95 cancel func()96 logger *logrus.Entry97}98func newStoppedVUHandle(99 parentCtx context.Context, getVU func() (lib.InitializedVU, error),100 returnVU func(lib.InitializedVU),101 nextIterationCounters func() (uint64, uint64),102 config *BaseConfig, logger *logrus.Entry,103) *vuHandle {104 ctx, cancel := context.WithCancel(parentCtx)105 return &vuHandle{106 mutex: &sync.Mutex{},107 parentCtx: parentCtx,108 getVU: getVU,109 nextIterationCounters: nextIterationCounters,110 config: config,111 canStartIter: make(chan struct{}),112 state: stopped,113 ctx: ctx,114 cancel: cancel,115 logger: logger,116 returnVU: returnVU,117 }118}119func (vh *vuHandle) start() (err error) {120 vh.mutex.Lock()121 defer vh.mutex.Unlock()122 switch vh.state {123 case starting, running:124 return nil // nothing to do125 case toGracefulStop: // we raced with the loop, lets not return the vu just to get it back126 vh.logger.Debug("Start")127 close(vh.canStartIter)128 vh.changeState(running)129 case stopped, toHardStop: // we need to reactivate the VU and remake the context for it130 vh.logger.Debug("Start")131 vh.initVU, err = vh.getVU()132 if err != nil {133 return err134 }135 vh.activeVU = vh.initVU.Activate(getVUActivationParams(136 vh.ctx, *vh.config, vh.returnVU, vh.nextIterationCounters))137 close(vh.canStartIter)138 vh.changeState(starting)139 }140 return nil141}142// just a helper function for debugging143func (vh *vuHandle) changeState(newState stateType) {144 // vh.stateH = append(vh.stateH, newState)145 atomic.StoreInt32((*int32)(&vh.state), int32(newState))146}147func (vh *vuHandle) gracefulStop() {148 vh.mutex.Lock()149 defer vh.mutex.Unlock()150 switch vh.state {...
