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`
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
- 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.
- 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)
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.
