- KVDB/StateDB
- Pass config parameters in a Config type instead of using many
arguments in constructor.
- Add new parameter `NoLast` which disables having an opened DB with a
checkpoint to the last batchNum for thread-safe reads. Last will be
disabled in the StateDB used by the TxSelector and BatchBuilder.
- Add new parameter `NoGapsCheck` which skips checking gaps in the list
of checkpoints and returning errors if there are gaps. Gaps check
will be disabled in the StateDB used by the TxSelector and
BatchBuilder, because we expect to have gaps when there are multiple
coordinators forging (slots not forged by our coordinator will leave
gaps).
- kvdb
- Fix path in Last when doing `setNew`
- Only close if db != nil, and after closing, always set db to nil
- This will avoid a panic in the case where the db is closed but
there's an error soon after, and a future call tries to close
again. This is because pebble.Close() will panic if the db is
already closed.
- Avoid calling pebble methods when a the Storage interface already
implements that method (like Close).
- statedb
- In test, avoid calling KVDB method if the same method is available for
the StateDB (like MakeCheckpoint, CurrentBatch).
- eth
- In *EventByBlock methods, take blockHash as input argument and use it
when querying the event logs. Previously the blockHash was only taken
from the logs results *only if* there was any log. This caused the
following issue: if there was no logs, it was not possible to know if
the result was from the expected block or an uncle block! By querying
logs by blockHash we make sure that even if there are no logs, they
are from the right block.
- Note that now the function can either be called with a
blockNum or blockHash, but not both at the same time.
- sync
- If there's an error during call to Sync call resetState, which
internally resets the stateDB to avoid stale checkpoints (and a
corresponding invalid increase in the StateDB batchNum).
- During a Sync, after very batch processed, make sure that the StateDB
currentBatch corresponds to the batchNum in the smart contract
log/event.
Fixes the case where there is a PoolTxs of type Exit with fee 0 for a
TokenID. Before this commit the Coordinator was not sending the
accumulated fee (which has value 0) to the Coordinator account for that
TokenID, with this commit the Coordinator always sends the accumulated
fee even when the value is 0 to match the hermez circom circuits
behaviour.
Also added a test to check the values and that also sends the proof to a
real proof server to check that can generate a valid proof.
Last db view is an opened pebble db which always contains a checkpoint from the
last batch. Methods to access this last batch are thread safe so that views of
the last checkpoint can be made anywhere and with a consistent view of the
state.
PoolL2Tx.Info contains information about the status & State of the
transaction. As for example, if the Tx has not been selected in the last
batch due not enough Balance at the Sender account, this reason would
appear at this parameter.
This will help the client (wallet, batchexplorer, etc) to reason why a
L2Tx is not selected in the forged batches.
L2Tx.TokenID is not on the data obtained by the Synchronizer from the
blockchain, but is set by the TxProcessor when processing the
transactions in the StateDB.
- 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`
The smart contracts were updated at some point and there have been some changes
in slot calculation. Update these values in the synchronizer and test auction
smart contract implementaiton.
- Add tests connecting TxSelector, BatchBuilder, ZKInputs, ProofServer
- Added test to check that the signatures of the PoolL2Txs from the L2DB
pool can be verified, to check that the parameters of the PoolL2Tx match
the original parameters signed before inserting them into the L2DB
- TxProcessor move txCompressedDataEmpty inside the if of tp.zki!=nil
- Abstract generation of transactions for ZKInput tests to avoid code
repetition
- used at txprocessor & test/zkproof tests
- Til
- update Til users BJJ key generation for better js tests
compatibility
- Common
- PoolL2Tx to L2Tx use AuxToIdx in case that ToIdx is 0
- Update ZKInputs parameter descriptions
- TxProcessor
- Fix AccumulatedFees in case that there is no CoordIdx for that token
- Fix zki.NewExit usage
- Use same order for AccumulatedFees & FeeIdx & FeePlanTokens
- Add Nonce usage to ExitLeafs
- Update TestZKInput6 and check its compatibility with circom Hermez
circuits
- Debug Batch File
- Add details about why a batch is scheduled to be L1Batch or regular
- Add timestamps in time and blockNumber of important events
- Use a different naming for the files (batchNum + timestamp)
- Coordinator:
- To make decisions and store debug info, always use the current block that
is being mined, instead of the last mined block
- Add missing Fees to CoordAccounts after processing PoolL2Txs
- Add Nonces checks for L2Txs (txs with incorrect nonces not included
in the selection)
- Add missing MakeCheckpoint() at the LocalAccountsDB once the
selection is done
- Add TxSelector test of full flow using Til.SetBlockchainMinimumFlow0
checking balances & parameters
- Til
- tests that were using `til.SetBlockchainMinimumFlow0` have been
updated, as now the L1CoordinatorTxs are placed simulating TxSelector
creation (when needed, not before)
- Add `EthSk` to `tc.User` to allow to sign `AccoutCreationAuths` at
the tests flows
- TxProcessor
- for L2Txs get TokenID from tx.FromIdx Account.TokenID instead than
- update tests vectors for new values
from tx.TokenID (which not always is set)
- Common
- move TxIDsFromL2Txs & TxIDsFromPoolL2Txs from `coordinator` to
`common` to allow usage from other packages
- Refactor the migrations code so that packr is only called (via an init
function in `db/utils.go`).
- When loading the migrations, make sure there is at least one migration,
otherwise panic (this would happen if the node is built incorrectly)
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.
- Fix AccountCreationAuth.HashToSign (was using `[]byte("0x...")`, which
uses the bytes of the string. Now uses the bytearray of the compressed
BJJ public key (compatible with js implementation))
- Update AccountCreationAuth to last specification (add to hash
parameters ChainID & HermezAddress)
- Add missing test to AccountCreationAuth
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
Previously the Synchronizer required the initial variables of the smart
contracts to be passed as a configuration parameter (that the node took from
the configuration file). The same applied to the blockNumber.
The last update of the smart contracts introduced events for each smart
contract constructor (initializer), which allows querying the initial variables
as well as the initial block number for each smart contract.
Now the synchronizer uses this information, and thus the initial variables and
the starting block numbers have been removed from the configuration.
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`.
- 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

- Add new tables and extend existing ones to reflect updates regarding
events from the smart contracts

- 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

- purge l2txs due to timeout
- mark l2txs at the different states

- 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
