* core: total ordering flush (#212)Mission Liao2018-10-181-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Implement flush * Panic for all errors from total-ordering * Fix test failure All DAGs generated by blocks-generator would trigger round switching. * Add NewBlocksGeneratorConfig * Add test caes for numChains changes * Resize internal structures * Perform total ordering based on current numChains * Fix not a valid DAG checking * Comparing blocks by height is not correct * Fix blocks from future round are delivered first by revealer * Make sure only picking one candidate in one chain. Blocks on the same chain in different rounds would not have acking relation. * Fix stuffs * Fix the issue that two candidates from the same chain are picked. * Rework candidateChainMapping * Add test case for phi, k changed * Refine testing code for round change * Add breakpoints in global vector * Remove not a valid dag checking. * Adding comments * Add check to forward acking * Fix vet failure * Prepareing height record with breakpoint * Fixup: add check to make sure delivered round IDs are increasing.

* core: update data model to reflect new model (#157)Wei-Ning Huang2018-10-011-3/+8
| | | | | | Update data model: 1) Remove witness ack. 2) Add round to block. 3) Update governance interface.
* core: move crypto to core/crypto (#140)Mission Liao2018-09-261-1/+1
| | | | | | | | | - Move key-holder to authenticator Make core.keyHolder public as core.Authenticator, it is not required to make this part an interface. - Make private when there is no need to go public. - Fix data race
* core: add blockpool (#121)Mission Liao2018-09-201-6/+21
| | | | | | core.blockPool is used to cache blocks arrived out-of-order. Our consensus should retry those blocks after their acking blocks added to lattice.

* core: types: use []byte for block Payload type (#101)Wei-Ning Huang2018-09-121-6/+3
| | | | | 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.

|
* core: tune performance (#73)Mission Liao2018-08-281-14/+48
| | | | | | | | | | | | | | | | | | | | | | - 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.

* core: refine Application interface and add Governance interface (#24)Wei-Ning Huang2018-07-311-0/+6
| | | | | | | Add a new Governance interface for interaction with the governance contract. Also remove the ValidateBlock call in application interface as the application should validate it before putting it into the consensus module. A new BlockConverter interface is also added. The consensus module should accept the BlockConverter interface in future implementation, and use the Block() function to get the underlying block info.
* Add new sorting method for blocksMission Liao2018-07-311-0/+15
| | | | - Add types.ByHeight to sort slice of blocks by their heights. - Add test case for sorting methods of types.Block.
* Add acking module (#13)Haoping Ku2018-07-301-6/+7
| | | | | | | * Refactor and add acking module Extract acking module for unit testing. This commit splits functions into small pieces for better understanding and easy unit testing.
