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
- 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.
- 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- In Synchronizer, first match a Rollup delayed withdrawn request, with the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with the delayed withdrawn.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.
- Add ZKInputs parser to JSON
- Update ProcessTxs to last go-merkletree version changes
- Add StateDB test to generate ZKInputs to check inside a circom circuit
- Small fix at Til CoordinatorTx.LoadAmount=0
- Node
- Updated configuration to initialize the interface to all the smart
contracts
- Common
- Moved BlockData and BatchData types to common so that they can be
shared among: historydb, til and synchronizer
- Remove hash.go (it was never used)
- Remove slot.go (it was never used)
- Remove smartcontractparams.go (it was never used, and appropriate
structs are defined in `eth/`)
- Comment state / status method until requirements of this method are
properly defined, and move it to Synchronizer
- Synchronizer
- Simplify `Sync` routine to only sync one block per call, and return
useful information.
- Use BlockData and BatchData from common
- Check that events belong to the expected block hash
- In L1Batch, query L1UserTxs from HistoryDB
- Fill ERC20 token information
- Test AddTokens with test.Client
- HistryDB
- Use BlockData and BatchData from common
- Add `GetAllTokens` method
- Uncomment and update GetL1UserTxs (with corresponding tests)
- Til
- Rename all instances of RegisterToken to AddToken (to follow the smart
contract implementation naming)
- Use BlockData and BatchData from common
- Move testL1CoordinatorTxs and testL2Txs to a separate struct
from BatchData in Context
- Start Context with BatchNum = 1 (which the protocol defines to be the
first batchNum)
- In every Batch, set StateRoot and ExitRoot to a non-nil big.Int
(zero).
- In all L1Txs, if LoadAmount is not used, set it to 0; if Amount is not
used, set it to 0; so that no *big.Int is nil.
- In L1UserTx, don't set BatchNum, because when L1UserTxs are created
and obtained by the synchronizer, the BatchNum is not known yet (it's
a synchronizer job to set it)
- In L1UserTxs, set `UserOrigin` and set `ToForgeL1TxsNum`.
- Implement new TxID spec that distinguishes L1UserTx and L1CoordinatorTx
- Replace some type []*Foo by []Foo
- Fix HistoryDB & L2DB bug: in case of error, a rollback was applied and the returned error was nil
- Reorder inserts in historydb.NewHistoryDB() to follow foreign key dependencies
- Add initial synchronizer test with test.Client (for now, only tested l1UserTxs, blocks, addToken)
- Update L1UserTx event in test.Client
Add TxID calculation & New{Layer}Tx Type
New{Layer}Tx methods that compute the `TxID` & `TxType` values from the
transaction values:
- NewL1Tx
- NewL2Tx
- NewPoolL2Tx
Add TxID Scanner & Valuer for database/sql
HistoryDB & L2DB & API packages tests will need to be addapted to the
TestTransaction generation once is done.
