- 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.
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.
- 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`
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`.
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 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
In statedb:
- Store all values using prefixes for keys to allow iteration
- Add methods MTGetRoot, GetAccounts
Implement debugapi, an http server with debugging endpoints:
- debugAPI.GET("sdb/batchnum", a.handleCurrentBatch)
- debugAPI.GET("sdb/mtroot", a.handleMTRoot)
- debugAPI.GET("sdb/accounts", a.handleAccounts)
- debugAPI.GET("sdb/accounts/:Idx", a.handleAccount)
Add linter checks to GHA & Fix code to pass lints.
The linters added are:
- whitespace: Tool for detection of leading and trailing whitespace
- gosec: Inspects source code for security problems
- gci: Gci control golang package import order and make it always deterministic
- misspell: Finds commonly misspelled English words in comments
- gomnd: An analyzer to detect magic numbers
The file utils/utils.go is excluded from the checks of gomnd, as uses magic numbers through the code
- 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
Previously as the txprocessor.go methods were specific for the BatchBuilder,
the MTCreateAccount & CreateAccount and MTUpdateAccount & UpdateAccount were
also designed to be used by BatchBuilder and TxSelector depending on the
MerkleTree usage calling one kind of method or anotherone.
But now that this methods are being called directly by the StateDB (through the
methods in txprocessors.go), to allow also the methods usage from the
Synchronizer, there can not be the MT and no-MT methods separated, so this
commit unifies MTCreateAccount with CreateAccount, and MTUpdateAccount with
UpdateAccount, which internally will update the MerkleTree depending if the
specific StateDB in usage has the MerkleTree defined or not.
