| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * core: fix block timestamp (#529) * Remove TODO dMoment is still required when the block timestamp of the genesis block is still need to be verified. * Refine timestamp when preparing blocks * Add timestamp checking in sanity check * Revert code to patch position when preparing * Remove TODOs that seems meaningless now * Remove TODOs related to refactoring * core: remove finalization (#531) - Remove types.FinalizationResult, randomness field would be moved to `types.Block` directly. - Add a placeholder for types.Block.Randomness field for blocks proposed from round < DKGDelayRound. (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

* core: refine DKG aborting (#512)Mission Liao2019-03-238-42/+81
| | | | | | | | | | | | | | | | | | * 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

Therefore, the last interval we could use is BA's interval. * Check ctx in inifite loop * Disable this panic temporary If a fast sync triggered by receiving types.AgreementResult from later position, this panic would be triggered 100%, ex. current-round: 1, change-notary-height: 120, agreeemnt-result from round:2 height:121 However, I don't have easy way to fix it temporary. * Lower down the test size for TCP * Fix typo * Fixup: revert the removed panic

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | 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.
