Types ¶
type BaseConfig ¶
type BaseConfig struct {
BootstrapDir string
// contains filtered or unexported fields
}
BaseConfig is the general config for the FlowNodeBuilder
type FlowNodeBuilder ¶
type FlowNodeBuilder struct {
BaseConfig BaseConfig
NodeID flow.Identifier
Logger zerolog.Logger
Me *local.Local
Tracer module.Tracer
MetricsRegisterer prometheus.Registerer
Metrics Metrics
DB *badger.DB
Storage Storage
ProtocolEvents *events.Distributor
State protocol.State
Middleware *p2p.Middleware
Network *p2p.Network
MsgValidators []network.MessageValidator
FvmOptions []fvm.Option
// root state information
RootBlock *flow.Block
RootQC *flow.QuorumCertificate
RootResult *flow.ExecutionResult
RootSeal *flow.Seal
RootChainID flow.ChainID
// contains filtered or unexported fields
}
FlowNodeBuilder is the builder struct used for all flow nodes It runs a node process with following structure, in sequential order Base inits (network, storage, state, logger)
PostInit handlers, if any
Components handlers, if any, wait sequentially Run() <- main loop Components destructors, if any
func FlowNode ¶
func FlowNode(role string) *FlowNodeBuilder
FlowNode creates a new Flow node builder with the given name.
func (*FlowNodeBuilder) Component ¶
func (fnb *FlowNodeBuilder) Component(name string, f func(*FlowNodeBuilder) (module.ReadyDoneAware, error)) *FlowNodeBuilder
Component adds a new component to the node that conforms to the ReadyDone interface.
When the node is run, this component will be started with `Ready`. When the node is stopped, we will wait for the component to exit gracefully with `Done`.
func (*FlowNodeBuilder) ExtraFlags ¶
func (fnb *FlowNodeBuilder) ExtraFlags(f func(*pflag.FlagSet)) *FlowNodeBuilder
ExtraFlags enables binding additional flags beyond those defined in BaseConfig.
func (*FlowNodeBuilder) Module ¶
func (fnb *FlowNodeBuilder) Module(name string, f func(builder *FlowNodeBuilder) error) *FlowNodeBuilder
Module enables setting up dependencies of the engine with the builder context.
func (*FlowNodeBuilder) MustNot ¶
func (fnb *FlowNodeBuilder) MustNot(err error) *zerolog.Event
MustNot asserts that the given error must not occur.
If the error is nil, returns a nil log event (which acts as a no-op). If the error is not nil, returns a fatal log event containing the error.
func (*FlowNodeBuilder) PostInit ¶
func (fnb *FlowNodeBuilder) PostInit(f func(node *FlowNodeBuilder)) *FlowNodeBuilder
func (*FlowNodeBuilder) Run ¶
func (fnb *FlowNodeBuilder) Run()
Run initiates all common components (logger, database, protocol state etc.) then starts each component. It also sets up a channel to gracefully shut down each component if a SIGINT is received.
type Metrics ¶
type Metrics struct {
Network module.NetworkMetrics
Engine module.EngineMetrics
Compliance module.ComplianceMetrics
Cache module.CacheMetrics
Mempool module.MempoolMetrics
}
type Storage ¶
type Storage struct {
Headers storage.Headers
Index storage.Index
Identities storage.Identities
Guarantees storage.Guarantees
Receipts storage.ExecutionReceipts
Results storage.ExecutionResults
Seals storage.Seals
Payloads storage.Payloads
Blocks storage.Blocks
Transactions storage.Transactions
Collections storage.Collections
Setups storage.EpochSetups
Commits storage.EpochCommits
Statuses storage.EpochStatuses
}
