- 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.

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.

* separate test utility and interface implementation
for test.Governance.
* add test.State.
* integrate test.State to test.Governance.
test.State is mainly used to emulate state propagation
on fullnode.

* Replace "log.*" with logger.
* Add simple logger to log with log package.
* Add debug logs to all calls to these interfaces:
- core.Application
- core.Governance
- core.Network
* Add Stringer to these types:
- types.DKGComplaint
- types.AgreementResult
- types.DKGMasterPublicKey
- types.DKGFinalize

* 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.

* Sync dMoment for all consensus core
* App check for randomness ignore round 0
|
|
|
|
|
|

* Extract types.FinalizationResult
* Change interface:
- Application.BlockConfirmed returns whole block.
- Application.BlockDelivered returns partial result.

Update data model:
1) Remove witness ack.
2) Add round to block.
3) Update governance interface.
|
| |
|
|
|

|
|
|
|
|
| |
* Refine core.Governance interface
- Remove types.NodeID from interface declaration.
- All parameter should be round based.
* Add core.NodeSetCache
* Agreement accepts map of nodeID directly.
* test.Transport.Peers method return public keys.
|

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.

- 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

* 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.

A shard is basically DEXON v1 components,
except the strongly acked part, including:
- maintaining lattice structure
- total ordering
- generate consensus timestamp
|
| |
|
| |
|
|
|
|
|
| |
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.

- 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.

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.

(#37)
|
|
* Make Sequencer return slice of blocks.
* Fix naming issue
The function 'getHeightVecto' would return ackingStatusVector.
* Fix comment error.
* Add methods to collect info when proposing blocks.
* Add test.App
* Add test.Gov
* Move this type to core.types to avoid cyclic import.
* Add core.Consensus
* Move getMedianTime, interpoTime to util

is required when testing core.Consensus.

* Remove core.blocklattice
* Define 'infinity' in core/total-ordering
This definition is defined in core/blocklattice originally.
* Fix a bug when processing the same block twice.
* Integrate simulation with core.Consensus
core.Consensus is a replacement of core.Blocklattice
* Fix the comment to use sigular form.
* Move lock mechanism to sub modules.
* phi should be 2*fmax+1
* Fixup: should aborting when the validator is added
* Fix for new block fields
* Fix the bug that the total ordering sequence is wrong.
