- API
- When updating network info, handle cases where no batches exists and
where no forgers exists
- cli/node
- Update `cfg.buidler.toml` config file to a working version
- common
- Add new smart contract structs and extend some existing ones to
reflect updates regarding events from the smart contracts
- SQL
- Add new tables and extend existing ones to reflect updates regarding
events from the smart contracts
- db/historydb
- Add functions to insert new smart contract events data
- Fix unclosed rows that led to inconsistent sql driver state (replace
NamedQuery by NamedExec). This fixes the error:
`pq: unexpected Parse response 'C'`
- db/l2db
- Close rows after usage
- eth
- In Rollup event, introduce a new UpdateBucketsParameter when there's a
SafeMode event, with `SafeMode = true`
- synchronizer
- synchronize new events
- avoid calling `auction.CanForge` before the genesisBlock to avoid
getting a revert.
- Common
- Add `IdxNonce` type used to track nonces in accounts to invalidate
l2txs in the pool
- Config
- Update coordinator config will all the new configuration parameters
used in the coordinator
- Coordinator
- Introduce the `Purger` to track how often to purge and do the job when
needed according to a configuration.
- Implement the methods to invalidate l2txs transactions due to l2txs
selection in batches. For now these functions are not used in favour
of the `Purger` methods, which check ALL the l2txs in the pool.
- Call Invalidation and Purging methods of the purger both when the
node is forging (in the pipeline when starting a new batch) and when
the node is not forging (in coordinator when being notified about a
new synced block)
- L2DB:
- Implement `GetPendingUniqueFromIdxs` to get all the unique idxs from
pending transactions (used to get their nonces and then invalidate
txs)
- Redo `CheckNonces` with a single SQL query and using `common.IdxNonce`
instead of `common.Account`
- StateDB:
- Expose GetIdx to check errors when invalidating pool txs
- Synchronizer:
- Test forged L1UserTxs processed by TxProcessor
- Improve checks of Effective values
- TxSelector:
- Expose the internal LocalStateDB in order to check account nonces in
the coordinator when not forging.
- Common
- Move ErrTODO and ErrDone to common for usage where needed.
- Coordinator
- Move prover types to prover package
- Handle reorgs, stopping the pipeline when necessary
- Handle ethereum transaction errors by stopping the pipeline
- In case of ethereum transaction revert, check for known revert causes
(more revert causes can be added to handle more cases)
- Fix skipped transactions in TxManager confirmation logic
- Cancel and wait for provers to be ready
- Connect L2DB to:
- purge l2txs due to timeout
- mark l2txs at the different states
- Connect HistoryDB to query L1UserTxs to forge in an L1Batch
- L2DB
- Skip update functions when the input slices have no values (to avoid a
query with no values that results in an SQL error)
- StateDB
- In LocalStateDB, fix Reset when mt == nil
- Prover (new package)
- Rename the interface to Prover
- Rename the mock struct to Mock
- Extend Prover interface methods to provide everything required by the
coordinator
- Begin implementing required http client code to interact with server
proof (not tested)
- Synchronizer:
- Add LastForgeL1TxsNum to Stats
- Test/Client
- Update Auction logic to track slots in which there's no forge during
the time before the deadline (following the solidity implementation)
- 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.
- Implement new TxID spec that distinguishes L1UserTx and L1CoordinatorTx
- Replace some type []*Foo by []Foo
- Fix HistoryDB & L2DB bug: in case of error, a rollback was applied and the returned error was nil
- Reorder inserts in historydb.NewHistoryDB() to follow foreign key dependencies
- Add initial synchronizer test with test.Client (for now, only tested l1UserTxs, blocks, addToken)
- Update L1UserTx event in test.Client
- gofmt - Gofmt checks whether code was gofmt-ed. By default this tool runs
with -s option to check for code simplification
- goimports - Goimports does everything that gofmt does. Additionally it checks
unused imports
- golint - Golint differs from gofmt. Gofmt reformats Go source code, whereas
golint prints out style mistakes
- checks the uncommented exported functions & types
Update the code to fix the lint checks.
Add linter checks to GHA & Fix code to pass lints.
The linters added are:
- whitespace: Tool for detection of leading and trailing whitespace
- gosec: Inspects source code for security problems
- gci: Gci control golang package import order and make it always deterministic
- misspell: Finds commonly misspelled English words in comments
- gomnd: An analyzer to detect magic numbers
The file utils/utils.go is excluded from the checks of gomnd, as uses magic numbers through the code
- Update GHA lint.yml increasing timeout time to avoid GHA Lint errors
- Update common.BatchNum & common.Idx & common.Nonce usage in StateDB
- Add abstraction method of processTxs to StateDB
- Which will be used by Synchronizer & BatchBuilder
