Previously the coordinator was erroneously using Slot.BatchesLen to determine
when anyone can forge. The correct behaviour is implmenented with the boolean
flag `ForgerCommitment`, that is set to true only when there's a batch before
the deadline within a slot.
Delete Slot.BatchesLen, and the synchronization code of this value from the
Synchronizer, as this is not needed
- Common:
- Rename Block.EthBlockNum to Block.Num to avoid unneeded repetition
- API:
- Add UpdateNetworkInfoBlock to update just block information, to be
used when the node is not yet synchronized
- Node:
- Call API.UpdateMetrics and UpdateRecommendedFee in a loop, with
configurable time intervals
- Synchronizer:
- When mapping events by TxHash, use an array to support the possibility
of multiple calls of the same function happening in the same
transaction (for example, a smart contract in a single transaction
could call withdraw with delay twice, which would generate 2 withdraw
events, and 2 deposit events).
- In Stats, keep entire LastBlock instead of just the blockNum
- In Stats, add lastL1BatchBlock
- Test Stats and SCVars
- Coordinator:
- Enable writing the BatchInfo in every step of the pipeline to disk
(with JSON text files) for debugging purposes.
- Move the Pipeline functionality from the Coordinator to its own struct
(Pipeline)
- Implement shouldL1lL2Batch
- In TxManager, implement logic to perform several attempts when doing
ethereum node RPC calls before considering the error. (Both for calls
to forgeBatch and transaction receipt)
- In TxManager, reorganize the flow and note the specific points in
which actions are made when err != nil
- HistoryDB:
- Implement GetLastL1BatchBlockNum: returns the blockNum of the latest
forged l1Batch, to help the coordinator decide when to forge an
L1Batch.
- EthereumClient and test.Client:
- Update EthBlockByNumber to return the last block when the passed
number is -1.
- API:
- Modify the constructor so that hardcoded rollup constants don't need
to be passed (introduce a `Config` and use `configAPI` internally)
- Common:
- Update rollup constants with proper *big.Int when required
- Add BidCoordinator and Slot structs used by the HistoryDB and
Synchronizer.
- Add helper methods to AuctionConstants
- AuctionVariables: Add column `DefaultSlotSetBidSlotNum` (in the SQL
table: `default_slot_set_bid_slot_num`), which indicates at which
slotNum does the `DefaultSlotSetBid` specified starts applying.
- Config:
- Move coordinator exclusive configuration from the node config to the
coordinator config
- Coordinator:
- Reorganize the code towards having the goroutines started and stopped
from the coordinator itself instead of the node.
- Remove all stop and stopped channels, and use context.Context and
sync.WaitGroup instead.
- Remove BatchInfo setters and assing variables directly
- In ServerProof and ServerProofPool use context instead stop channel.
- Use message passing to notify the coordinator about sync updates and
reorgs
- Introduce the Pipeline, which can be started and stopped by the
Coordinator
- Introduce the TxManager, which manages ethereum transactions (the
TxManager is also in charge of making the forge call to the rollup
smart contract). The TxManager keeps ethereum transactions and:
1. Waits for the transaction to be accepted
2. Waits for the transaction to be confirmed for N blocks
- In forge logic, first prepare a batch and then wait for an available
server proof to have all work ready once the proof server is ready.
- Remove the `isForgeSequence` method which was querying the smart
contract, and instead use notifications sent by the Synchronizer to
figure out if it's forging time.
- Update test (which is a minimal test to manually see if the
coordinator starts)
- HistoryDB:
- Add method to get the number of batches in a slot (used to detect when
a slot has passed the bid winner forging deadline)
- Add method to get the best bid and associated coordinator of a slot
(used to detect the forgerAddress that can forge the slot)
- General:
- Rename some instances of `currentBlock` to `lastBlock` to be more
clear.
- Node:
- Connect the API to the node and call the methods to update cached
state when the sync advances blocks.
- Call methods to update Coordinator state when the sync advances blocks
and finds reorgs.
- Synchronizer:
- Add Auction field in the Stats, which contain the current slot with
info about highest bidder and other related info required to know who
can forge in the current block.
- Better organization of cached state:
- On Sync, update the internal cached state
- On Init or Reorg, load the state from HistoryDB into the
internal cached state.
- Node
- Updated configuration to initialize the interface to all the smart
contracts
- Common
- Moved BlockData and BatchData types to common so that they can be
shared among: historydb, til and synchronizer
- Remove hash.go (it was never used)
- Remove slot.go (it was never used)
- Remove smartcontractparams.go (it was never used, and appropriate
structs are defined in `eth/`)
- Comment state / status method until requirements of this method are
properly defined, and move it to Synchronizer
- Synchronizer
- Simplify `Sync` routine to only sync one block per call, and return
useful information.
- Use BlockData and BatchData from common
- Check that events belong to the expected block hash
- In L1Batch, query L1UserTxs from HistoryDB
- Fill ERC20 token information
- Test AddTokens with test.Client
- HistryDB
- Use BlockData and BatchData from common
- Add `GetAllTokens` method
- Uncomment and update GetL1UserTxs (with corresponding tests)
- Til
- Rename all instances of RegisterToken to AddToken (to follow the smart
contract implementation naming)
- Use BlockData and BatchData from common
- Move testL1CoordinatorTxs and testL2Txs to a separate struct
from BatchData in Context
- Start Context with BatchNum = 1 (which the protocol defines to be the
first batchNum)
- In every Batch, set StateRoot and ExitRoot to a non-nil big.Int
(zero).
- In all L1Txs, if LoadAmount is not used, set it to 0; if Amount is not
used, set it to 0; so that no *big.Int is nil.
- In L1UserTx, don't set BatchNum, because when L1UserTxs are created
and obtained by the synchronizer, the BatchNum is not known yet (it's
a synchronizer job to set it)
- In L1UserTxs, set `UserOrigin` and set `ToForgeL1TxsNum`.
