| | | | | | * core: only qualified nodes can participant BA * core: remove leader calculation from node set cache
* core: clean TODOs (#539)Mission Liao2019-04-013-34/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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

| | | | | | | | | | | | | | | | | | | | | | | * Capitalize log * Fix DKG aborting hangs Make sure reset cc.dkg to nil in runDKG * Remember to purge tsig verfier too * Replace abortCh with context.Context * Fix obvious bug * Fixup: forever blockin at Wait method when runDKG is not called * Fixup: fix corner case If the Add(1) moved to runDKG under cc.dkgLock, we may not catch it after unlocking cc.dkgLock. * fixup
* core: height event handlers are not called (#509)Mission Liao2019-03-221-32/+36
| | | | | | | * Make utils.RoundEvent.ValidateNextRound non-blocking * Make NotifyHeight called blockingly * Trigger all height event handlers that should be triggered by initBlock * Fixup: forget the syncer part
* core: reset DKG (#502)Mission Liao2019-03-205-1/+57
| | | | | | | | | | | | | | * Allow utils.NodeSetCache to purge by rounds. * Purge utils.NodeSetCache when DKG reset. * Add a utils.RoundEvent handler to abort all previous running DKG * Fix test.App hangs in BlockDelivered when utils.RoundEvent is attached. ValidateNextRound is a blocking call and would block test.App.BlockDelivered.

* test: try to mitigate flaky tests (#498)Mission Liao2019-03-181-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add assertion to make sure all nodes are synced. * Retry round event with BA's interval We are about to modify lambdaDKG with block height, instead of timing. 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: fix issues when switching to core.Consensus (#418)Mission Liao2019-01-112-0/+94
| | | | | | | | | | | | | | | | - 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.
