* core: utils: add GetDKGNackThreshold methodWei-Ning Huang2019-08-271-0/+5
| | | | | | Nacking DKG requires a different threshold then DKG itself, since if there are more than t + 1 of node nacking a node, we can assume the node is actually dead.

(refer to core.NoRand) - Make the height of the genesis block starts from 1. (refer to types.GenesisHeight) - The fullnode's behavior of core.Governance.GetRoundHeight is (assume round-length is 100): - round: 0 -> 0 (we need to workaround this) - round: 1 -> 101 - round: 2 -> 201 - test.Governance already simulate this behavior, and the workaround is wrapped at utils.GetRoundHeight. * core: fix issues (#536) fixing code in these condition: - assigning position without initializing them and expected it's for genesis - compare height with 0

| | | | | | | | | | | | | | | | | | * Avoid aborting the DKG protocol registered later Although that DKG protocol would be registered after 1/2 round, both of them are triggered in separated go routine and we shouldn't assuem their execution order. * Capitalize logs * Add test * Return aborted when not running * Log DKG aborting result * Remove duplicated DKG abort

* syncer: avoid attacked by older AgreementResult when syncing (#471)Mission Liao2019-03-081-0/+8
| | | | | | | | | | | | One possible attack for syncer is: - byzantine nodes periodically broadcast some very old types.AgreementResults. - If some syncer receive those types.AgreementResult, they might synced directly while still fall behind other nodes. A quick workaround is ignore types.AgreementResults older than the chain tip when creating the syncer.Consensus instance.

* syncer: fix issues when switching to core.Consensus (#418)Mission Liao2019-01-119-68/+274
| | | | | | | | | | | | | | | | - when confirmed blocks passed to core.Consensus aren't continuous in position in some chain, the pulling would skip those missing blocks. - fix: when some block is missing, avoid adding it and all blocks after it to core.Consensus. - we need to avoid the receive channel of network module full. - fix: during switching to core.Consensus, we need to launch a dummy receiver to receive from receive channel of network module. - fix: between the period during core.Consensus created and before running, a dummy receiver is also required to receive from receive channel of network module.

| | | | | | | | | | | | | | | | | | | | | | | | | Make `test.StateChangeRequest` behaves like tx on ethereum: - Can be broadcasted and cached in a pool. - Uniquely indexed, and be removed after applied. Changes: - Make cloneDKGx functions in test.State as utilities. - Add hash and timestamp fields to test.StateChangeRequest. - Add two methods to test.State: - PackOwnRequests would pack all pending change requests owned by this instance as byte slice, and move them to global pending requests pool. - AddRequestsFromOthers would add pending change requests from others to global pending requests pool. - The method State.PackRequests now would pack requests in global pending requests pool. - The method State.Apply would remove corresponding StateChangeRequest by hash.
