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
- Implement Pipeline.prepareForgeBatchArgs()
- Add a minimal stress test for the coordinator (that also runs the
synchronizer)
- Update txprocessor.ProcessTxs() to return valid results for batches without
transactions
- Add the boilerplate for the corresponding test, leaving as TODO the
zkInput values
- Update prover client to use the same point format as proof server (projective)
- Update interface of TxSelector.GetCoordIdxs to also return the authorizations
to create accounts that go with the l1CoordinatorTxs.
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
When the synchronizer queries the unforged L1UserTxs, sort them by position
Swap the order of calls setL1UserTxEffectiveAmounts and addBatch in
AddBlockSCData because otherwise, for reasons I dont understand, the item_id of
the txs doesn't follow the position of the txs.
For each tx, move the logic of setting the Type and TxID to separate functions,
so that they can be called when necessary.
In synchronizer, set all the required fields using the `SetID` and `SetType`
for l2txs when needed. This is necessary because the `ProcessTxs()` works with
`common.PoolL2Tx`, which misses some fields from `common.L2Tx`, and because
`ProcessTxs()` needs the Type to be set, but at the same time `ProcessTxs()`
sets the Nonce, which is required for the `TxID`.
- 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`.
- Update IntermediateState FinalAccFee values to fit in the Circom circuit expected inputs
- Add ZKInputs generation test with transactions generated by Til
(TestZKInputs6)
- BatchBuilder: remove redundant MakeCheckpoint call
- Update tx processor of Exit & ForceExit types
- Update ZKInputs generation related to Exit transactions
- Add TestZKInputs5 which adds tests generation of ZKInputs compatible
with Circom circuits including Exit (L2) & ForceExit (L1) transaction types
- Add StateDB test to check max DepositAmount case
- 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.
- StateDB fix process txs of type CreateAccountDepositTransfer & DepositTransfer
- Add TestZKInputs3 & TestZKInputs4 which:
- have a compatible check in js version to check Circom circuits
compatibility
- adds test of tx type of CreateAccountDepositTransfer &
DepositTransfer
- 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.
- Separate ZKInputs tests at StateDB package
- Small fix at ZKInputs generation FeeIdxs length
- Fees related parameters at ZKInputs works properly
- Add ZKInputs generation test with fees (`TestZKInputs1`), which output
has been tested with circom to ensure compatibility
- Add SignatureConstant to L1Tx.TxCompressedData
- ZKInputs generation works initial version working and compatible with circom Hermez circuit
- Lots of small updates for circuits compatibility
- Update version (with new changes) of `go-iden3-crypto` & `go-merkletree`
- 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)
