Types

type Broker

type Broker interface {
	Send(event events.Event)
}

type Commander

type Commander interface {
	CommandSync(ctx context.Context, cmd txn.Command, payload proto.Message, f func(error), bo *backoff.ExponentialBackOff)
}

type Config

type Config struct {
	Level encoding.LogLevel `long:"log-level"`
}

Config represent the configuration of the collateral engine.

func NewDefaultConfig

func NewDefaultConfig() Config

NewDefaultConfig creates an instance of the package specific configuration, given a pointer to a logger instance to be used for logging within the package.

type Engine

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

func New

func New(log *logging.Logger, config Config, broker Broker, topology ValidatorTopology, version string) *Engine

func (*Engine) BeginBlock

func (e *Engine) BeginBlock(ctx context.Context, blockHeight uint64)

BeginBlock is called at the beginning of the block, to mark the current block height and check if there are proposals that are accepted/rejected. If there is more than one active proposal that is accepted (unlikely) we choose the one with the earliest upgrade block.

func (*Engine) Cleanup

func (e *Engine) Cleanup(ctx context.Context)

Cleanup is called by the abci before the final snapshot is taken to clear remaining state. It emits events for the accepted and rejected proposals.

func (*Engine) GetState

func (e *Engine) GetState(k string) ([]byte, []types.StateProvider, error)

func (*Engine) GetUpgradeStatus

func (e *Engine) GetUpgradeStatus() types.UpgradeStatus

GetUpgradeStatus is an RPC call that returns the status of an upgrade.

func (*Engine) HasChanged

func (e *Engine) HasChanged(k string) bool

func (*Engine) Keys

func (e *Engine) Keys() []string

func (*Engine) LoadState

func (e *Engine) LoadState(ctx context.Context, p *types.Payload) ([]types.StateProvider, error)

func (*Engine) Namespace

func (e *Engine) Namespace() types.SnapshotNamespace

func (*Engine) OnRequiredMajorityChanged

func (e *Engine) OnRequiredMajorityChanged(_ context.Context, requiredMajority num.Decimal) error

func (*Engine) SetReadyForUpgrade

func (e *Engine) SetReadyForUpgrade()

SetReadyForUpgrade is called by abci after a snapshot has been taken and the process is ready to be shutdown.

func (*Engine) Stopped

func (e *Engine) Stopped() bool

func (*Engine) TimeForUpgrade

func (e *Engine) TimeForUpgrade() bool

TimeForUpgrade is called by abci at the beginning of the block (before calling begin block of the engine) - if a block height for upgrade is set and is equal to the last block's height then return true.

func (*Engine) UpgradeProposal

func (e *Engine) UpgradeProposal(ctx context.Context, pk string, upgradeBlockHeight uint64, vegaReleaseTag string) error

UpgradeProposal records the intention of a validator to upgrade the protocol to a release tag at block height.

type ValidatorTopology

type ValidatorTopology interface {
	IsTendermintValidator(pubkey string) bool
	IsSelfTendermintValidator() bool
	NumberOfTendermintValidators() uint
}
