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
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
- 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

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`

- avoid calling `auction.CanForge` before the genesisBlock to avoid
getting a revert.
- Add InvalidData flag to L1Tx

- Update ZKInputs & HashGlobalInputs to last spec of the protocol
(massive migrations)
- TxProcessor check correctness of L1Txs

(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.
- 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.
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.
