Types

type MutableStateConsistencyPredicate 

type MutableStateConsistencyPredicate func(mutableState workflow.MutableState) bool

type UpdateWorkflowAction 

type UpdateWorkflowAction struct {
	Noop               bool
	CreateWorkflowTask bool
	// Abort all "Workflow Updates" (not persistence updates) after persistence operation is succeeded but WF lock is not released.
	AbortUpdates bool
}

type UpdateWorkflowActionFunc 

type UpdateWorkflowActionFunc func(WorkflowLease) (*UpdateWorkflowAction, error)

func ResolveDuplicateWorkflowID added in v1.24.0 

func ResolveDuplicateWorkflowID(
	shardContext shard.Context,
	workflowKey definition.WorkflowKey,
	namespaceEntry *namespace.Namespace,
	newRunID string,
	currentState enumsspb.WorkflowExecutionState,
	currentStatus enumspb.WorkflowExecutionStatus,
	currentStartRequestID string,
	wfIDReusePolicy enumspb.WorkflowIdReusePolicy,
	wfIDConflictPolicy enumspb.WorkflowIdConflictPolicy,
	currentWorkflowStartTime time.Time,
) (UpdateWorkflowActionFunc, error)

ResolveDuplicateWorkflowID determines how to resolve a workflow ID duplication upon workflow start according to the WorkflowIdReusePolicy (for *completed* workflow) or WorkflowIdConflictPolicy (for *running* workflow).

NOTE: this function assumes the workflow id reuse policy Terminate-if-Running has been migrated to the workflow id conflict policy Terminate-Existing before it is invoked.

An action (ie "mitigate and allow"), an error (ie "deny") or neither (ie "allow") is returned.

type VersionedRunID added in v1.24.0 

type VersionedRunID struct {
	RunID            string
	LastWriteVersion int64
}

type WorkflowConsistencyChecker 

type WorkflowConsistencyChecker interface {
	GetWorkflowCache() wcache.Cache
	GetCurrentRunID(
		ctx context.Context,
		namespaceID string,
		workflowID string,
		lockPriority locks.Priority,
	) (string, error)
	GetWorkflowLease(
		ctx context.Context,
		reqClock *clockspb.VectorClock,
		workflowKey definition.WorkflowKey,
		lockPriority locks.Priority,
	) (WorkflowLease, error)

	GetWorkflowLeaseWithConsistencyCheck(
		ctx context.Context,
		reqClock *clockspb.VectorClock,
		consistencyPredicate MutableStateConsistencyPredicate,
		workflowKey definition.WorkflowKey,
		lockPriority locks.Priority,
	) (WorkflowLease, error)
}

type WorkflowConsistencyCheckerImpl 

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

func NewWorkflowConsistencyChecker 

func NewWorkflowConsistencyChecker(
	shardContext shard.Context,
	workflowCache wcache.Cache,
) *WorkflowConsistencyCheckerImpl

func (*WorkflowConsistencyCheckerImpl) GetCurrentRunID 

func (c *WorkflowConsistencyCheckerImpl) GetCurrentRunID(
	ctx context.Context,
	namespaceID string,
	workflowID string,
	lockPriority locks.Priority,
) (runID string, retErr error)

func (*WorkflowConsistencyCheckerImpl) GetWorkflowCache added in v1.19.0 

func (c *WorkflowConsistencyCheckerImpl) GetWorkflowCache() wcache.Cache

func (*WorkflowConsistencyCheckerImpl) GetWorkflowLease added in v1.24.0 

func (c *WorkflowConsistencyCheckerImpl) GetWorkflowLease(
	ctx context.Context,
	reqClock *clockspb.VectorClock,
	workflowKey definition.WorkflowKey,
	lockPriority locks.Priority,
) (WorkflowLease, error)

func (*WorkflowConsistencyCheckerImpl) GetWorkflowLeaseWithConsistencyCheck added in v1.25.0 

func (c *WorkflowConsistencyCheckerImpl) GetWorkflowLeaseWithConsistencyCheck(
	ctx context.Context,
	reqClock *clockspb.VectorClock,
	consistencyPredicate MutableStateConsistencyPredicate,
	workflowKey definition.WorkflowKey,
	lockPriority locks.Priority,
) (WorkflowLease, error)

The code below should be used when custom workflow state validation is required. If consistencyPredicate failed (thus detecting a stale workflow state) workflow state will be cleared, and mutable state will be reloaded.

type WorkflowLease added in v1.24.0 

type WorkflowLease interface {
	GetContext() workflow.Context
	GetMutableState() workflow.MutableState
	GetReleaseFn() wcache.ReleaseCacheFunc
}

func NewWorkflowLease added in v1.24.0 

func NewWorkflowLease(
	context workflow.Context,
	releaseFn wcache.ReleaseCacheFunc,
	mutableState workflow.MutableState,
) WorkflowLease

func NewWorkflowWithSignal 

func NewWorkflowWithSignal(
	shard shard.Context,
	namespaceEntry *namespace.Namespace,
	workflowID string,
	runID string,
	startRequest *historyservice.StartWorkflowExecutionRequest,
	signalWithStartRequest *workflowservice.SignalWithStartWorkflowExecutionRequest,
) (WorkflowLease, error)
