* core: core.Lattice supports config change (#276)Mission Liao2018-11-011-3/+1
| | | | | | | | | | | Besides making core.Lattice supports config change, This PR also include the first test for below scenario: - Configuration changes are registered before test running - Those changes are carried/broadcasted as payload of blocks - Only one node would initiate these changes, however, all nodes would finally receive/apply those changes to their own test.Governance instance.

* core: Some sync functions (#220)Jimmy Hu2018-10-171-2/+6
|
* core: genesis consensus timestamp (#217)Mission Liao2018-10-171-1/+3
| | | | | | | | | | * Refine the initial value for empty time slot. * Fix DATA RACE netowrkConnection is reset for each test, however, our Consensus instance is not stopped after one test is finished, they might continue use network interface for a while.
* core: check if flush is required when round switching in total-ordering (#197)Mission Liao2018-10-151-24/+8
|
* core: modify interface (#194)Mission Liao2018-10-121-2/+6
| | | | * Add a new method to notify full node about round cutting. * Modify interface to return error when preparing block
* core: latticeData supports config change (#190)Mission Liao2018-10-121-5/+8
| | | | | | | | | | | | | | | * Add test for num of chains changes. * Return error in latticeData.prepareBlock * Compare two positions * Modify chainStatus from height-based to index-based. * Fix consensus to use round variable * Remove sanity check in chainStatus * Fixup: refine sanity check - verify if round switching is required or not by chainTip's config. - make the logic in sanity check more clear - pospone acking relationship checking, they are more expensive to check.
* core: change interface (#193)Mission Liao2018-10-111-1/+1
| | | | | | | * Extract types.FinalizationResult * Change interface: - Application.BlockConfirmed returns whole block. - Application.BlockDelivered returns partial result.
* core: Move BlockConfirmed to Application interface (#192)Mission Liao2018-10-111-1/+1
| | | | | | | | When a block is confirmed, all its txs are permitted to be executed. Therefore, exporting this method provides more and earlier information about txs to be executed, and helps application layer to process txs more efficiently.
* core: types: fix nodeID generation (#191)Wei-Ning Huang2018-10-111-1/+1
| | | | | Use ethereum style nodeID generation (keccak on compressed public key without the first byte).
* core: Fix timestamp (#182)Jimmy Hu2018-10-081-3/+1

* core: find block in db (#174)Mission Liao2018-10-051-12/+16
| | | | | | | | | | | | | | | | | | | | * 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.
