func (*AckMsgPairCache) AddMsgPair 

func (a *AckMsgPairCache) AddMsgPair(pair *MsgPair)

AddMsgPair will add an ack to the cache if it is not too old, and it is an ack+msg pair 

We assume that all msgs being added have been added to our processlist, and therefore
the current working height and they are valid.

func (*AckMsgPairCache) Expire 

func (a *AckMsgPairCache) Expire(newHeight int)

Expire for the AckMsgPairCache will expire all acks older than 2 blocks. 

TODO: Is iterating over a map extra cost? Should we have a sorted list?
		Technically we can just call delete NewHeight-2 as long as we always
		Update every height

func (*AckMsgPairCache) Get

type CrossReplayFilter 

type CrossReplayFilter struct {
	Currentheight int
	LowestHeight  int
	// contains filtered or unexported fields
}

CrossReplayFilter checks for old messages across reboots based on the salts inside the ack messages. It saves all salts of leaders it sees while running. On reboot, it will ignore all messages that have an old salt (for a set duration). After the duration, no new salts are saved (extra overhead we don't need) and will stop ignoring messages based on salts (so a single leader reboot will rejoin the network).

func NewCrossReplayFilter 

func NewCrossReplayFilter(path string) *CrossReplayFilter

func (*CrossReplayFilter) AddSalt 

func (c *CrossReplayFilter) AddSalt(height uint32, salt [8]byte) error

ExistOldSalt checks to see if the salt existed on the previous boot

func (*CrossReplayFilter) ExistSalt 

func (c *CrossReplayFilter) ExistSalt(salt [8]byte) (bool, error)

Exists check if the hash is in the replay filter, and if it encounters a db error, it will report false

func (*CrossReplayFilter) Run 

func (c *CrossReplayFilter) Run()

Run is a simple loop that ensures we discard old data we do not need.

type EntrySync 

type EntrySync struct {
	// contains filtered or unexported fields

EntrySync is responsible for sending the requests to fetch missing entries to the network. (aka 2nd pass sync) The general algorithms are as follows:

Sync: Start with the last known complete height 1. Load the DBlock and iterate over all EBlock hashes 2. For each EBlock, iterate over the Entry hashes 3. If the DB has the entry, skip, otherwise add the hash to the ask queue 4. Collate all missing entry hashes for each EBlock and add it to eblock queue 5. Inform state we are processing up to that eblock

Ask: 1. Look at the first N records of the ask queue 2. If the entry exists, remove it from queue 3. If it's the first time or time threshold passed, send a request to the network

Check: 1. Look at the first record of the eblock queue 2. Go through all missing records and check if they exist 3. If there are still missing records, wait and go back to 1 4. If the eblock is finished, inform the state we have all the entries up to that eblock

Because we have to go back to a previous state should the network be partitioned and we are on a separate branch, we need to log our state periodically so we can reset to a state prior to the network partition. The need to go back to a SaveState should be rare. And even more rare would be the need to go back two levels. However, it is possible that a minority partition is able to see a level of consensus and save a state to disk that the majority of the nodes did not see. However it is not possible for this to occur more than once. This is because any consensus a node can see requires that all the nodes saw the previous consensus.
