- 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`
- Upgrade go-merkletree version to include the last changes of Pebble
that fixes the cgo issues (which should fix#453), from:
c2b05f12d7
- TxSelector
- Remove parameter batchNum for GetL2TxSelection & GetL1L2TxSelection
- Add checks of ToBJJ & ToEthAddr when ToIdx>255
- Avoid getting the sender account twice to get the TokenID of a l2tx
- Add test to check that selected L2Txs are sorted by Nonce
- Discard L2Tx that return error at ProcessL2Txs
- executed `go mod tidy`
- StateDB
- Update GetIdxByEthAddrBJJ to return ErrToIdxNotFound when idx not found, so can be checked at upper levels
- TxSelector
- rm CoordIdxsDB that is no longer needed (also related methods)
- add `getCoordIdx` method to get the Coordinator Idx for a given TokenID
- Update coordinator account creation related to new TokenIDs from L2Txs
- Reorganize GetL1L2TxSelection
- return CoordIdxs used in the selection
- Update go-merkletree version which avoids marshaling Siblings to json
with 'null' value in case of empty array
Load an ethereum keystore when the node is started in coordinator mode. The
private key corresponding to the forger address must be imported into the
keystore before running the node in coordinator mode. You can see an examples
in `cli/node/load-sk-example.sh`.
On the Circuits uses the name `nTx` (and on the tests `maxTx`), but
Contracts `maxTx`. On Go we had both variables, but really only used
one, now at Go we use `MaxTx` to refer to the maximum number of
transactions.
Introduce a constructor parameter for the StateDB called `keep`, which tells
how many checkpoints to keep. When doing a new checkpoint, if the number of
existing checkpoints exeeds `keep`, the oldest ones will be deleted.

- 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

- 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

- 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

- 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

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
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)
- 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.
- 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
- 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.
- Update StateDB ProcessTxs fees collection
- Update ProcessTxs tests to last StateDB & Til changes
- Til Blockchain L2Txs remove Nonce generation, update tests accordingly
- Update Til Set to test fees
