Leo Chen	53a5c3c856	HAR-65: support node removal after node is offline ... In p2p library, I added a channel notification mechansim when it failed to send messages after retries. The failed p2p.Peer will be notified to caller via the channel. Then the leader knows which peer is offline and adds to an offline list. Before another consensus is started, the ledaer will check the offline list and remove the node from the validator list. Leader will have to broadcast the Pong message to all validators to sync the public key list. Signed-off-by: Leo Chen <leo@harmony.one>	6 years ago

Leo Chen	0407dc559b	HAR-65: send redundant Pong messages to validators ... This is necessary to make sure every validators can receive the latest list of PublicKeys. Without this patch, the deploy.sh running locally can hardly reach consensus for 60+ validators in one shard. With this patch, the deploy.sh test can reach consensus on 100 validators in one shard. Noted, we have to use the following command line to test the peer discovery. We have to -m <NUM_OF_VALIDATOR_IN_THE_SHARD> to stop leader from initiating consensus if not all validators are registered. The reason is new validator may join the shard in the middle of a consensus. However, we have only one PublicKeys list in leader. It will be updated once a new validator joined, and it causes inconsistency of the PublicKeys between leader and validators and it will failure the CoSi verification. ./deploy.sh -p -m <NUM_OF_VALIDATOR> local_config.txt Signed-off-by: Leo Chen <leo@harmony.one>	6 years ago

Leo Chen	44f5e85433	[HAR-83] peer discovery works under account model ... fix a bug to update the bitmap on the leader in account model Issue: Can only reach consensus once, and then got the following errors. Failed to create new block Error="nonce too low" This is because of new validators joined the shard and their state are not sync'ed, thus we have not enough nonce.

Leo Chen	91f804eb13	[HAR-5] Leader populates public keys to all validators ... All validators should have the identical list of public keys as the leader.
