Types

type Executor

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

func NewExecutor

func NewExecutor(cdb *datastore.CachedDB, vm vmState, cs conservativeState, lg log.Log) *Executor

func (*Executor) Execute

func (e *Executor) Execute(ctx context.Context, lid types.LayerID, block *types.Block) error

Execute transactions in the specified block and update the conservative cache.

func (*Executor) ExecuteOptimistic

func (e *Executor) ExecuteOptimistic(
	ctx context.Context,
	lid types.LayerID,
	tickHeight uint64,
	rewards []types.AnyReward,
	tids []types.TransactionID,
) (*types.Block, error)

ExecuteOptimistic executes the specified transactions and returns a block that contains only successfully executed transactions.

func (*Executor) Revert

func (e *Executor) Revert(ctx context.Context, revertTo types.LayerID) error

Revert reverts the VM state and conservative cache to the given layer.

type Mesh

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

Mesh is the logic layer above our mesh.DB database.

func NewMesh

func NewMesh(cdb *datastore.CachedDB, c layerClock, trtl system.Tortoise, exec *Executor, state conservativeState, logger log.Log) (*Mesh, error)

NewMesh creates a new instant of a mesh.

func (*Mesh) AddBallot

func (msh *Mesh) AddBallot(ctx context.Context, ballot *types.Ballot) (*types.MalfeasanceProof, error)

AddBallot to the mesh.

func (*Mesh) AddBlockWithTXs

func (msh *Mesh) AddBlockWithTXs(ctx context.Context, block *types.Block) error

AddBlockWithTXs adds the block and its TXs in into the database.

func (*Mesh) AddTXsFromProposal

func (msh *Mesh) AddTXsFromProposal(ctx context.Context, layerID types.LayerID, proposalID types.ProposalID, txIDs []types.TransactionID) error

AddTXsFromProposal adds the TXs in a Proposal into the database.

func (*Mesh) EpochAtxs

func (msh *Mesh) EpochAtxs(epoch types.EpochID) ([]types.ATXID, error)

func (*Mesh) GetATXs

func (msh *Mesh) GetATXs(ctx context.Context, atxIds []types.ATXID) (map[types.ATXID]*types.VerifiedActivationTx, []types.ATXID)

GetATXs uses GetFullAtx to return a list of atxs corresponding to atxIds requested.

func (*Mesh) GetLayer

func (msh *Mesh) GetLayer(lid types.LayerID) (*types.Layer, error)

GetLayer returns GetLayer i from the database.

func (*Mesh) GetRewards

func (msh *Mesh) GetRewards(coinbase types.Address) ([]*types.Reward, error)

GetRewards retrieves account's rewards by the coinbase address.

func (*Mesh) LastVerified

func (msh *Mesh) LastVerified() types.LayerID

LastVerified returns the latest layer verified by tortoise.

func (*Mesh) LatestLayer

func (msh *Mesh) LatestLayer() types.LayerID

LatestLayer - returns the latest layer we saw from the network.

func (*Mesh) LatestLayerInState

func (msh *Mesh) LatestLayerInState() types.LayerID

LatestLayerInState returns the latest layer we applied to state.

func (*Mesh) MeshHash

func (msh *Mesh) MeshHash(lid types.LayerID) (types.Hash32, error)

MeshHash returns the aggregated mesh hash at the specified layer.

func (*Mesh) ProcessLayer

func (msh *Mesh) ProcessLayer(ctx context.Context, lid types.LayerID) error

ProcessLayer reads latest consensus results and ensures that vm state is consistent with results. It is safe to call after optimistically executing the block.

func (*Mesh) ProcessLayerPerHareOutput

func (msh *Mesh) ProcessLayerPerHareOutput(ctx context.Context, layerID types.LayerID, blockID types.BlockID, executed bool) error

ProcessLayerPerHareOutput receives hare output once it finishes running for a given layer.

ProcessedLayer returns the last processed layer ID.

func (*Mesh) SetZeroBlockLayer

func (msh *Mesh) SetZeroBlockLayer(ctx context.Context, lid types.LayerID)

SetZeroBlockLayer advances the latest layer in the network with a layer that has no data.
