var (
	ErrWorkflowNotRunning  = autocore.ErrWorkflowNotRunning
	ErrSignalLimitExceeded = autocore.ErrSignalLimitExceeded

ErrWorkflowNotRunning is returned by the send paths when the addressed workflow has already reached a terminal state, and ErrSignalLimitExceeded when it has spent its signal history budget. Both are permanent for that workflow: re-sending cannot succeed.

var ErrInvalidWorkflowKey = autocore.ErrInvalidWorkflowKey

ErrInvalidWorkflowKey is returned by GetWorkflow when the key is malformed.

View Source 
var ErrReservedIdempotencyKeyPrefix = autocore.ErrReservedIdempotencyKeyPrefix

ErrReservedIdempotencyKeyPrefix is returned by RunWorkflow when the caller's idempotency key uses the prefix the engine keeps for itself.

View Source 
var ErrWorkflowNotFound = autocore.ErrWorkflowNotFound

ErrWorkflowNotFound is returned by GetWorkflow when no workflow exists for the given key.

type Engine 

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

func NewEngine 

func NewEngine(opts *Options) (*Engine, error)

func (*Engine) CancelWorkflow 

func (e *Engine) CancelWorkflow(ctx context.Context, workflowKey, workflowToken string) error

CancelWorkflow requests cancellation of the workflow addressed by workflowKey. workflowToken is that workflow's token, or empty to present none. Cancellation is an asynchronous best-effort signal: the workflow transitions to a canceled state on a later replay round. Returns ErrInvalidWorkflowKey if the key is malformed, ErrWorkflowNotFound if no such workflow exists, or ErrInvalidWorkflowToken if the token does not verify.

func (*Engine) GetWorkflow 

func (e *Engine) GetWorkflow(ctx context.Context, workflowKey, workflowToken string) (*Workflow, error)

GetWorkflow returns a snapshot of the workflow addressed by workflowKey, the key string returned by RunWorkflow. workflowToken is that workflow's token. Returns ErrInvalidWorkflowToken if the token does not verify, or an error if the key is malformed.

This is the polled endpoint, so the workflow and the metadata its token is verified against come from one read of one row. Nothing is returned before the token verifies; a workflow that is not there yields the same refusal as a wrong token, since a caller that cannot verify must not learn whether it exists.

func (*Engine) RunWorkflow 

func (e *Engine) RunWorkflow(ctx context.Context, namespaceID int64, idempotencyKey string, opts *RunWorkflowOptions) (*RunWorkflowResult, error)

RunWorkflow submits a RunWorkflow workflow and mints its workflow token plus a channel token for every distinct channel the arguments carry. Returns the autocore-assigned workflow key.

If a workflow with the given (namespaceID, idempotencyKey) already exists, it returns that workflow's key without re-creating it, with tokens signed by the secret that workflow was created with. Those tokens are only handed over if opts.TokenBinding is the binding that workflow registered, so holding an idempotency key is not holding the workflow.

Returns ErrInvalidChannelName for a channel the caller may not name, ErrReservedIdempotencyKeyPrefix for an idempotency key the caller may not use, ErrInvalidTokenBinding if the existing workflow registered a different binding, ErrWorkflowNotFound if it is gone by the time its secret is read back, and ErrMissingSigningSecret if it holds no secret to sign with.

func (*Engine) SendToChannel added in v19.2.0 

func (e *Engine) SendToChannel(ctx context.Context, agentKey api.AgentKey, channelToken string, sends []ChannelSend) error

SendToChannel puts each of sends onto the channel the module token addresses. Every send gets its own signal, keyed by its own idempotency key, so resending a batch lands nothing that already arrived.

func (*Engine) SendToWorkflowChannel added in v19.3.0 

func (e *Engine) SendToWorkflowChannel(ctx context.Context, idempotencyKey, channelToken, workflowToken string, value *pkg_autoflow.Value) error

SendToWorkflowChannel sends value into the channel the caller token addresses. The token is the capability handed out by RunWorkflow for a channel in the workflow input. workflowToken is the token of the workflow that channel belongs to, or empty to present none.

The supported parameters are: - file: name of a file, exposed by a module.

Module names are agent names, defined in doc/identity_and_auth.md.

	ModuleManager  ModuleManager
	MeterProvider  otelmetric.MeterProvider

	// PredeclaredProtoFiles is the set of proto file descriptors that

type RunWorkflowOptions added in v19.3.0 

type RunWorkflowOptions struct {

	Args                      []*pkg_autoflow.Value
	Kwargs                    []*pkg_autoflow.Kwarg
	ScheduleToCompleteTimeout time.Duration
	// TokenBinding is the value a re-submission must present to be handed this
	// workflow's tokens again. Required of every caller; empty registers none,
	// which leaves the workflow's tokens un-re-issuable for good.
	TokenBinding []byte
}

RunWorkflowOptions is what a caller passes to RunWorkflow. It is deliberately not RunWorkflowInput: that message is the workflow's own input and carries fields only flowcore may set, such as the signing secret and the entry function a parent picks for a child.

type RunWorkflowOutput

type RunWorkflowResult added in v19.3.0 

type RunWorkflowResult struct {
	WorkflowKey   string
	WorkflowToken string
	ChannelTokens []*pkg_autoflow.ChannelToken
}

RunWorkflowResult is what RunWorkflow returns. WorkflowToken is the capability to manage the workflow. ChannelTokens holds one send-only capability per distinct channel in the workflow input, in first-encounter order, and is empty when the input carries no channel.

type Transform added in v19.3.0 

type Transform struct {

type ValueConverter 

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

ValueConverter converts between AutoFlow proto Values and Starlark values.

Proto message Values (google.protobuf.Any) are resolved against the supplied descriptor set, falling back to the predeclared files. protoregistry.GlobalFiles is intentionally NOT consulted. Safe to use concurrently. A converter with a channel resolver installed is the exception: the resolver reaches into the running workflow's state, so that converter is confined to the workflow goroutine.

func NewValueConverter 

func NewValueConverter(predeclaredFiles *protoregistry.Files, descriptorSet *descriptorpb.FileDescriptorSet) *ValueConverter

NewValueConverter constructs a new ValueConverter. descriptorSet is optional, can be nil

func (*ValueConverter) FromStarlark

FromStarlark converts a Starlark value into a proto Value.

func (*ValueConverter) FromStarlarkIterable added in v19.3.0

func (*ValueConverter) ToStarlark 

func (c *ValueConverter) ToStarlark(v *pkg_autoflow.Value) (starlark.Value, error)

ToStarlark converts a proto Value into a Starlark value.

type ValueToStarlarkConverter added in v19.2.0 

type ValueToStarlarkConverter interface {
	ToStarlark(*pkg_autoflow.Value) (starlark.Value, error)
}

ValueToStarlarkConverter converts an AutoFlow proto Value into a Starlark value.

type Workflow 

type Workflow struct {

	IdempotencyKey string
	State          WorkflowState
	CreatedAt      time.Time
	UpdatedAt      time.Time
	Output         *RunWorkflowOutput
	Error          string
}

Workflow is a read-only snapshot of a workflow returned by GetWorkflow. Output holds the workflow's decoded output and is set only when the workflow completed; Error holds the failure message and is set only when it failed.

type WorkflowMetadata added in v19.3.0
