type ChainStore 

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

ChainStore is the main point of access to chain data.

Raw chain data is stored in the Blockstore, with relevant markers (genesis, latest head tipset references) being tracked in the Datastore (key-value store).

To alleviate disk access, the ChainStore has two ARC caches:

  1. a tipset cache
  2. a block => messages references cache.

func (cs *ChainStore) ReorgOps(ctx context.Context, a, b *types.TipSet) ([]*types.TipSet, []*types.TipSet, error)

ReorgOps takes two tipsets (which can be at different heights), and walks their corresponding chains backwards one step at a time until we find a common ancestor. It then returns the respective chain segments that fork from the identified ancestor, in reverse order, where the first element of each slice is the supplied tipset, and the last element is the common ancestor.

If an error happens along the way, we return the error with nil slices.

type HeadChangeCoalescer 

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

HeadChangeCoalescer is a stateful reorg notifee which coalesces incoming head changes with pending head changes to reduce state computations from head change notifications.

func NewHeadChangeCoalescer 

func NewHeadChangeCoalescer(fn ReorgNotifee, minDelay, maxDelay, mergeInterval time.Duration) *HeadChangeCoalescer

NewHeadChangeCoalescer creates a HeadChangeCoalescer.

func (*HeadChangeCoalescer) Close 

func (c *HeadChangeCoalescer) Close() error

Close closes the coalescer and cancels the background dispatch goroutine. Any further notification will result in an error.

func (*HeadChangeCoalescer) HeadChange 

func (c *HeadChangeCoalescer) HeadChange(revert, apply []*types.TipSet) error

HeadChange is the ReorgNotifee callback for the stateful coalescer; it receives an incoming head change and schedules dispatch of a coalesced head change in the background.

type HeadChangeEvt 

type HeadChangeEvt struct {
	From        types.TipSetKey
	FromHeight  abi.ChainEpoch
	To          types.TipSetKey
	ToHeight    abi.ChainEpoch
	RevertCount int
	ApplyCount  int
}

type ReorgNotifee 

type ReorgNotifee = func(rev, app []*types.TipSet) error

ReorgNotifee represents a callback that gets called upon reorgs.

func WrapHeadChangeCoalescer 

func WrapHeadChangeCoalescer(fn ReorgNotifee, minDelay, maxDelay, mergeInterval time.Duration) ReorgNotifee

WrapHeadChangeCoalescer wraps a ReorgNotifee with a head change coalescer. minDelay is the minimum coalesce delay; when a head change is first received, the coalescer will 

wait for that long to coalesce more head changes.

maxDelay is the maximum coalesce delay; the coalescer will not delay delivery of a head change 

more than that.

mergeInterval is the interval that triggers additional coalesce delay; if the last head change was 

within the merge interval when the coalesce timer fires, then the coalesce time is extended
by min delay and up to max delay total.

type WeightFunc 

type WeightFunc func(ctx context.Context, stateBs bstore.Blockstore, ts *types.TipSet) (types.BigInt, error)
