Pending (once

merged to master):
Update golangci-lint version to v1.37.1

db/historydb
db/l2db
- 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)
- When a tx fails, check and discard all the failed transactions before
sending the message to stop the pipeline. This will avoid sending
consecutive messages of stop the pipeline when multiple txs are
detected to be failed consecutively. Also, future txs of the same
pipeline after a discarded txs are discarded, and their nonces reused.
- Robust handling of nonces:
- If geth returns nonce is too low, increase it
- If geth returns nonce too hight, decrease it
- If geth returns underpriced, increase gas price
- If geth returns replace underpriced, increase gas price
- Add support for resending transactions after a timeout
- Store `BatchInfos` in a queue
- Pipeline
- When an error is found, stop forging batches and send a message to the
coordinator to stop the pipeline with information of the failed batch
number so that in a restart, non-failed batches are not repated.
- When doing a reset of the stateDB, if possible reset from the local
checkpoint instead of resetting from the synchronizer. This allows
resetting from a batch that is valid but not yet sent / synced.
- Every time a pipeline is started, assign it a number from a counter. This
allows the TxManager to ignore batches from stopped pipelines, via a
message sent by the coordinator.
- Avoid forging when we haven't reached the rollup genesis block number.
- Add config parameter `StartSlotBlocksDelay`: StartSlotBlocksDelay is the
number of blocks of delay to wait before starting the pipeline when we
reach a slot in which we can forge.
- When detecting a reorg, only reset the pipeline if the batch from which
the pipeline started changed and wasn't sent by us.
- Add config parameter `ScheduleBatchBlocksAheadCheck`:
ScheduleBatchBlocksAheadCheck is the number of blocks ahead in which the
forger address is checked to be allowed to forge (apart from checking the
next block), used to decide when to stop scheduling new batches (by
stopping the pipeline). For example, if we are at block 10 and
ScheduleBatchBlocksAheadCheck is 5, eventhough at block 11 we canForge,
the pipeline will be stopped if we can't forge at block 15. This value
should be the expected number of blocks it takes between scheduling a
batch and having it mined.
- Add config parameter `SendBatchBlocksMarginCheck`:
SendBatchBlocksMarginCheck is the number of margin blocks ahead in which
the coordinator is also checked to be allowed to forge, apart from the
next block; used to decide when to stop sending batches to the smart
contract. For example, if we are at block 10 and
SendBatchBlocksMarginCheck is 5, eventhough at block 11 we canForge, the
batch will be discarded if we can't forge at block 15.
- Add config parameter `TxResendTimeout`: TxResendTimeout is the timeout
after which a non-mined ethereum transaction will be resent (reusing the
nonce) with a newly calculated gas price
- Add config parameter `MaxGasPrice`: MaxGasPrice is the maximum gas price
allowed for ethereum transactions
- Add config parameter `NoReuseNonce`: NoReuseNonce disables reusing nonces
of pending transactions for new replacement transactions. This is useful
for testing with Ganache.
- Extend BatchInfo with more useful information for debugging
- 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`
- In stats, store full last batch instead of just last batch number
- Instead of calculating a nextSlot from scratch every time, update the
current struct (only updating the forger info if we are Synced)
- Afer every processed batch, check that the calculated StateDB MTRoot
matches the StateRoot found in the forgeBatch event.
- 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).
- 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
- Remove MaxL1CoordTxs parameter from the TxSelector because this parameter
doesn't exist
- Use ChainID in l1tx byte encoding
- Pass txprocessor configuration to batch builder via an existing parameter
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 IntermediateState FinalAccFee values to fit in the Circom circuit expected inputs
- Add ZKInputs generation test with transactions generated by Til
(TestZKInputs6)
- BatchBuilder: remove redundant MakeCheckpoint call
Add HashGlobalInputs for ZKInputs compatible with js & circom circuits version.
Compatible with hermeznetwork/commonjs at version: c6a1448db5
(c6a1448db5)
- 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
- Update GHA lint.yml increasing timeout time to avoid GHA Lint errors
- Update common.BatchNum & common.Idx & common.Nonce usage in StateDB
- Add abstraction method of processTxs to StateDB
- Which will be used by Synchronizer & BatchBuilder
