When querying the init event for each smart contract, bound the search from
block genesis-24h to block genesis. Otherwise, this query in geth synced to
mainnet takes too long.

coordinator:
- Add config `ForgeDelay`: ForgeDelay is the delay after which a batch is
forged if the slot is already commited. If set to 0s, the coordinator
will continously forge at the maximum rate.
- Add config `ForgeNoTxsDelay`: ForgeNoTxsDelay is the delay after which a
batch is forged even if there are no txs to forge if the slot is already
commited. If set to 0s, the coordinator will continously forge even if
the batches are empty.
- Add config `GasPriceIncPerc`: GasPriceIncPerc is the percentage increase
of gas price set in an ethereum transaction from the suggested gas price
by the ehtereum node
- Remove unused configuration parameters `CallGasLimit` and `GasPriceDiv`
- Forge always regardless of configured forge delay when the current slot is
not yet commited and we are the winner of the slot
synchronizer:
- Don't log with error (use warning) level when there's a reorg and the
queried events by block using the block hash returns "unknown block".
- Add AmountF new parameter to ZKInputs
- Update ZKInputs test vectors with float40 checked with circom circuits
- Small fix at eth/rollup.go with lenL1L2TxsBytes with new length of
Float40
- eth
- In EventsByBlock calls ignore blockNum if blockHash != nil. This fixes
the issue where a blockNumber and blockHash was being passed, which the
eth events query function doesn't allow, causing the synchronizer to fail
at every iteration.
- Node/Config
- Add Coordinator.Debug.RollupVerifierIndex to force choosing a particular
verifier by index in the Rollup smart contract.
- kvdb
- Fix path in Last when doing `setNew`
- Only close if db != nil, and after closing, always set db to nil
- This will avoid a panic in the case where the db is closed but
there's an error soon after, and a future call tries to close
again. This is because pebble.Close() will panic if the db is
already closed.
- Avoid calling pebble methods when a the Storage interface already
implements that method (like Close).
- statedb
- In test, avoid calling KVDB method if the same method is available for
the StateDB (like MakeCheckpoint, CurrentBatch).
- eth
- In *EventByBlock methods, take blockHash as input argument and use it
when querying the event logs. Previously the blockHash was only taken
from the logs results *only if* there was any log. This caused the
following issue: if there was no logs, it was not possible to know if
the result was from the expected block or an uncle block! By querying
logs by blockHash we make sure that even if there are no logs, they
are from the right block.
- Note that now the function can either be called with a
blockNum or blockHash, but not both at the same time.
- sync
- If there's an error during call to Sync call resetState, which
internally resets the stateDB to avoid stale checkpoints (and a
corresponding invalid increase in the StateDB batchNum).
- During a Sync, after very batch processed, make sure that the StateDB
currentBatch corresponds to the batchNum in the smart contract
log/event.
- cli / node
- Update handler of SIGINT so that after 3 SIGINTs, the process terminates
unconditionally
- coordinator
- Store stats without pointer
- In all functions that send a variable via channel, check for context done
to avoid deadlock (due to no process reading from the channel, which has
no queue) when the node is stopped.
- Abstract `canForge` so that it can be used outside of the `Coordinator`
- In `canForge` check the blockNumber in current and next slot.
- Update tests due to smart contract changes in slot handling, and minimum
bid defaults
- TxManager
- Add consts, vars and stats to allow evaluating `canForge`
- Add `canForge` method (not used yet)
- Store batch and nonces status (last success and last pending)
- Track nonces internally instead of relying on the ethereum node (this
is required to work with ganache when there are pending txs)
- Handle the (common) case of the receipt not being found after the tx
is sent.
- Don't start the main loop until we get an initial messae fo the stats
and vars (so that in the loop the stats and vars are set to
synchronizer values)
- eth / ethereum client
- Add necessary methods to create the auth object for transactions manually
so that we can set the nonce, gas price, gas limit, etc manually
- Update `RollupForgeBatch` to take an auth object as input (so that the
coordinator can set parameters manually)
- synchronizer
- In stats, add `NextSlot`
- In config, add Debug.MeddlerLogs to enable meddler debug logs. This only
affects the node started via cli, tests swill ran with `meddler.Debug = true`
- Remove unused ethereum client functions and config parameters
- Document all the config parameters
Load an ethereum keystore when the node is started in coordinator mode. The
private key corresponding to the forger address must be imported into the
keystore before running the node in coordinator mode. You can see an examples
in `cli/node/load-sk-example.sh`.
Update usage of `*babyjub.PublicKey` to `babyjub.PublicKeyComp`
- when the key is not defined, internally is used `babyjub.EmptyBJJComp`, which is a `[32]byte` of zeroes of type `babyjub.PublicKeyComp`
- the API continues returning `nil` when the key is not defined
Previously the Synchronizer required the initial variables of the smart
contracts to be passed as a configuration parameter (that the node took from
the configuration file). The same applied to the blockNumber.
The last update of the smart contracts introduced events for each smart
contract constructor (initializer), which allows querying the initial variables
as well as the initial block number for each smart contract.
Now the synchronizer uses this information, and thus the initial variables and
the starting block numbers have been removed from the configuration.
- API:
- Replace `emergencyModeStaringTime` by `emercengyModeStartingBlock`
- Synchronizer:
- Track emergency mode starting block
- cli/node
- Add working coordinator config
- coordinator:
- Retry handler for synchronizer stats in case of error (instead of
waiting for the next block to try again)
- On init, trigger an initial call to the handler for synced block
before waiting for the synchronizer, to force the coordinator to start
its logic even if there's no new block right after the node has been
started (very useful for running in testnet where the frequency of
blocks is variable)
- Merge Msg for synced block and updated vars into one: `MsgSyncBlock`.
- 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)
- Add InvalidData flag to L1Tx
- Add BytesDataAvailability to L1Tx
- Update ZKInputs & HashGlobalInputs to last spec of the protocol
(massive migrations)
- TxProcessor check correctness of L1Txs
Compatible with hermeznetwork/commonjs v0.0.4
(c345239bba)
- 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.
Add HashGlobalInputs for ZKInputs compatible with js & circom circuits version.
Compatible with hermeznetwork/commonjs at version: c6a1448db5
(c6a1448db5)
- In exit table, `instant_withdrawn`, `delayed_withdraw_request`, and
`delayed_withdrawn` were referencing batch_num. But these actions happen
outside a batch, so they should reference a block_num.
- Process delayed withdrawns:
- In Synchronizer, first match a Rollup delayed withdrawn request, with the
WDelayer deposit (via TxHash), and store the owner and token associated
with the delayed withdrawn.
- In HistoryDB: store the owner and token of a delayed withdrawal request
in the exit_tree, and set delayed_withdrawn when the withdraw is done in
the WDelayer.
- Update dependency of sqlx to master
- Last release of sqlx is from 2018 October, and it doesn't support
`NamedQuery` with a slice of structs, which is used in this commit.
- node:
- Extend config to add initial variables of the smart contracts used as
defaults before they are changed via events.
- In stopped channels, set size 1 so that panics are not witheld until the
node stops completely.
- common:
- In Smart Contract variables, comment:
- `WDelayerVariables.HermezRollupAddress` because it's not needed.
- `RollupVariables.Buckets` because there are no events for it, and for
now it's not used.
- historydb:
- Add functions to get and set smart contract variables.
- db:
- Add `Rollback` function in `utils.go` to reduce boilerplate in sql
transaction rollbacks in defers in db functions.
- Update `rollup_vars` and `auction_vars` (renamed from `consensus_vars`)
table, and add `wdelayer_vars` table.
- synchronizer:
- Synchronize WDelayer
- Handle SC variables properly
- test/ethclient:
- Add essential implementation of WDelayer
- Move smart contract constants and structs for variables to
common/{ethrollup.go, ethauction.go, ethwdelayer.go}:
- This removes repeated code of the structs for variables
- Allows reusing the constants and variables from all modules without
import cycles
- Remove unused common/scvars.go
- In common.BlockData, split data from each smart contract into a sepparate
field (Rollup, Auction, WDelayer). This affects the structures that til uses
as output, and HistoryDB in the AddBlockSCData.
- In Synchronizer:
- Pass starting block of each smart contract as config, instead of
incorrectly using the genesis block found in the acution constant (which
has a very different meaning)
- Use variable structs from common instead of an internal copy
- Synchronize more stuff (resolve some TODOs)
- Fix some issues found after initial testing with ganache
- In eth:
- In auction.go: Add method to get constants
- Update README to use ganache instead of buidlerevm as local blockchain
for testing
- Update env variables and test vectors to pass the tests with the
deployment in the ganache testnet.
- Use ethereum keys derived from paths (hdwallet) in testing to avoid
hardcoding private keys and generate the same keys from a mnemonic used
in the ganache tesnet.
Add transakcio set type definition, add set loading, move transakcio to
package, adapt branch to last master updates (fix compile due new common
types & git conflicts).
Update tests to pass the test, pending to adapt to new Transakcio
interface.
