- 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

(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

- 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.
- In SQL Tables, set rollup_vars.forge_l1_timeout to BIGINT (instead of BYTEA)
- In "bigint" encoding/decoding used with meddler, store the *big.Int as raw
bytes, instead of base64 to be more space efficient
Add HashGlobalInputs for ZKInputs compatible with js & circom circuits version.

- 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.
- Allow starting the DebugAPI from the node via config
- In StateDB:
- Make checkpoints when ProcessTxs() succeeds
- Remove extra hardcoded `statedb` path that was redundant
- Replace hardcoded `[:4]` by `[:]` when parsing idx, which failed because
idx is 6 bytes length now.
- Extra: In node, use waitgroup instead of `stoppedXXX` channels to wait for
syncrhonizer goroutines to finish.
Previously, the synchronizer test was extending the output from til to
precalculate many fields to compare it with the synchronizer and BD output.
Since this is useful outside of the syncrhonizer testing: move this
functionality to til via a function that extends the output
(til.Context.FillBlocksExtra).
Also, add new functionality: calculate fee idxs dynamically by setting a user
name, and calculate collected fees.
