* core: clean TODOs (#539)Mission Liao2019-04-011-35/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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: touch node cache even in reset (#537)Jimmy Hu2019-04-011-3/+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

ValidateNextRound is a blocking call and would block test.App.BlockDelivered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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

| | | | | | | | Since all DKG set members may ProposeCRS, but only one will get through, we need to be able to tell which round the CRS is intended for in order to skip CRS submission of the same round. Also this commit add check to make sure we have enough master public key when initializing DKGGroupPublicKey.

| | | | | | | | | | | | | | | | | | | | * Make sure block pool is large enough It's safe to use a larger blockPool when the number of chains is smaller. * Construct latticeData via config. * Seek acked blocks in blockdb when unable to find them in memory cache. In previous implementation, we assume our cache in memory is enough to perform DAG's sanity check. However, it's no longer true when the number of chains might be changed between rounds. * Simplify purge. Remove the relation to purge block by chainStatus.

* core: update governance interface and config (#145)Wei-Ning Huang2018-09-271-6/+11
| | | | | | 1) Remove RoundHeight from config. 2) NotarySet is not from governance contract, we get Node set intead. Notary set is caculated from the NodeSet using CRS. 3) CRS is not in the governance interface.

* core: add debug (#133)Mission Liao2018-09-251-15/+13
| | | | | | | | | | | | | | | | | | | | | * Split interface * Rename nonblocking-application to nonblocking Parts needs nonblocking gets more. * Implement core.nonBlocking based on interface split * Fix: the witness parent hash could be parent on compaction chain. * Rename Application.DeliverBlock to BlockDeliver To sync with naming of other methods. * Change methods' fingerprint - BlockConfirmed provides block hash only. - BlockDeliver provde a whole block.
* core: run first DKG at startup. (#129)Jimmy Hu2018-09-231-21/+163
|
* core: add shard (#127)Mission Liao2018-09-211-9/+9
| | | | | | | A shard is basically DEXON v1 components, except the strongly acked part, including: - maintaining lattice structure - total ordering - generate consensus timestamp
* core: refactor witness data processing flow (#124)Wei-Ning Huang2018-09-201-10/+42
| | | | | | | | | | | Since witness data need to include data from application after it processed a block (e.g. stateRoot). We should make the process of witness data asynchronous. An interface `BlockProcessedChan()` is added to the application interface to return a channel for notifying the consensus core when a block is processed. The notification object includes a byte slice (witenss data) which will be include in the final witness data object.

* core: rename Notary (Acks) to Witness (#118)Wei-Ning Huang2018-09-191-15/+15
|
* core: refine governance interface to reduce Get* methods (#114)Wei-Ning Huang2018-09-181-15/+19
| | | | | Since we have a bunch of static configurations in the governance contract, instead of using a Get* method for each of them, we instead implement a GetConfiguration() method to return a structure of the configurations.
* core: remove ticker parameter from NewConsensusMission Liao2018-09-181-8/+6
| | | | | | | | | - remove BlockProposingInterval, it's replaced by lambda. - remove ticker parameter of NewConsensus, ticker would be derived from governance. - leave a backdoor to hook the construction of ticker. - move 'Lambda' config from to consensus.
* core: move blockdb into core package and minor change on governance ↵Wei-Ning Huang2018-09-171-8/+8
| | | | | | | interface (#110) Since third party apps will possibly implement their only blockdb class, it make sense for the interface to be in core. Also add GetNumShards into the governance interface.
* cleanup (#109)Mission Liao2018-09-171-27/+24
| | | | | | - With context, we don't need stopChan - Remove core.BlockChain. - Remove unused variable.

* core: types: use []byte for block Payload type (#101)Wei-Ning Huang2018-09-121-2/+2
| | | | | Change payload type to []byte instead of [][]byte to make it more generic. The user of the consensus core should marshal the payload into a byte slice by themselves.

| | | | | - Replace map with slice Compared to slice, accessing to map is slower and the memory usage is inefficient.
* core: tune performance (#73)Mission Liao2018-08-281-0/+4
| | | | | | | | | | | | | | | | | | | | | | - Avoid using recursive function in critical path. - Do not write through when using levelDB. Things put to levelDB would be safe from panic even we didn't force to write through every time. - Dump count of confirmed blocks proposed by self. - Avoid allocating variables in loop. - Return length of acking node set, we only need that when total ordering. - Fix potential bug: make sure win records updated when acking height vectors of candidates are changed. - Keep dirty validators in slice. - Add cache for objects to ease the pressure to garbage collector. - Cache global acking status when total ordering. - Add method to recycle blocks. - Marshal JSON should be called once for each broadcast. - Make updateWinRecord called in parallel. - Log average / deviation of latencies when simulation finished.
