Integration tests staking v4 #3951

mariusmihaic · 2022-03-30T12:11:00Z

What's new

StakingV4DistributeAuctionToWaitingEpoch activation flag = epoch in which selected nodes from auction will be distributed to waiting list (used in node shuffler)
Added a new entry in MaxNodesChangeEnableEpoch config, which will have enable epoch = StakingV4DistributeAuctionToWaitingEpoch and will decrease the max nodes config with the number of shuffled out validators from all shards (e.g. from 3200 -> 2880, since we shuffle out 80 eligible validators per 4 shards)
Computation of available slots for auction nodes which will be selected based on topup as following:

availableSlots = maxNodes - currentNumberOfValidators - numOfNodesWhichWillBeShuffledOut

Integration tests

Added TestMetaProcessor struct which will create a predefined nodes configuration with provided params:

        numOfMetaNodes uint32,
	numOfShards uint32,
	numOfEligibleNodesPerShard uint32,
	numOfWaitingNodesPerShard uint32,
	numOfNodesToShufflePerShard uint32,
	shardConsensusGroupSize int,
	metaConsensusGroupSize int,
	numOfNodesInStakingQueue uint32,

All generated address have a fixed length which starts from index = 0 -> maxNumNodes (e.g. 00address-0 -> 0address-50)
Every node in waiting/eligible is associated with a different owner
All nodes in staking queue are owned by a single owner
Every node has the same top-up per node
It can Process n number of rounds by committing blocks in each of them and will display nodes config each time.

Added 2 integration tests:

TestStakingV4 which simulates a mainnet nodes configuration (400 meta nodes + 400 eligible and waiting/shard + 60 nodes in staking queue, each of them having the same topup per node) going through stakingV4Init, stakingV4Enable, stakingV4DistributeAuctionToWaiting epochs.
TestStakingV4MetaProcessor_ProcessMultipleNodesWithSameSetupExpectSameRootHash which simulates multiple TestMetaProcessor starting to process n epochs with the same initial setup. It is expected that there is not root hash mismatch at any epoch

Bugfixes

Deactivated flagCorrectNumNodesToStake flag in legacySystemSCs.go upon staking v4 enable epoch, since it used code related to staking queue (which is now obsolete)
Fixed a bug in which two nodes with the same top up would not be correctly sorted/compared by pubKey XOR randomness, resulting in root hash mismatches between meta shard nodes
Uint32 substraction underflow when computing available slots from auction list
setNodesPerShards in indexHashedNodesCoordinatorLite.go to also save shuffled out nodes
Race condition in already existing code from process/block/displayMetaBlock.go by adding a mutex for peakTPS

Refactor

Moved some testing code related to staking from systemSCs_test.go to testscommon/stakingCommon.go to be used in stakingV4 integration tests
NewFeeAccumulator constructor to return directly a new instance of *feeHandler instead of (*feeHandler, error) , since it could have never returned an error
Several stubs so that code in tests would not panic because of uninitialized memory

we have this for Uint64

Right, but I didn't want to cast to uint64, but have a separate function for it. Will move it in elrond-go-core in a separate task
