* 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

* 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

One possible attack for syncer is:
- byzantine nodes periodically broadcast some very
old types.AgreementResults.
- If some syncer receive those
types.AgreementResult, they might synced
directly while still fall behind other nodes.
A quick workaround is ignore
types.AgreementResults older than the chain tip
when creating the syncer.Consensus instance.

- 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.

error is mostly meaningless to fullnode, they
just need to retry it later.

Make `test.StateChangeRequest` behaves like tx
on ethereum:
- Can be broadcasted and cached in a pool.
- Uniquely indexed, and be removed after
applied.
Changes:
- Make cloneDKGx functions in test.State as
utilities.
- Add hash and timestamp fields to
test.StateChangeRequest.
- Add two methods to test.State:
- PackOwnRequests would pack all pending
change requests owned by this instance as
byte slice, and move them to global pending
requests pool.
- AddRequestsFromOthers would add pending
change requests from others to global
pending requests pool.
- The method State.PackRequests now would pack
requests in global pending requests pool.
- The method State.Apply would remove
corresponding StateChangeRequest by hash.

This info is required when application layer needs
to do something related to the underlying DAG, not
just compaction chain.

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.
|
| |
|
| |
|
| |
|
|
|
| |
- also add missing logs when calling Application.BlockDelivered.

* Fix bug: the block pool is not resized.
* Fix forward acking.
* Fix panic when total ordering
* Fix total ordering flush hang
The blocks arrived first might be not delivered before other block.
Therefore, if some last block of previous round arrived before last
blocks in other chains, and are not delivered when entering flush mode.
Their corresponding flush-ready flag won't be turned on.
* Fix bug in core.latticeData
Invalid chainID is not thrown when preparing blocks.

* Fix dummy error
* Check validity before apply state changes.
* Add RegisterConfigChange method to test.Governance
* Add SwitchToRemoteMode method to test.State

* Fix panic
Assume DAG would be increased to 7 chains at round 4.
When encounter the first block from round 4, this module would
attempt to resize its working set to the numChains in round 2 or 3.
* Add a check to make sure consensus timestamps are increasing
* Fix consensus timestamp rewind
