Previous to this commit, there were cases where being
len(nonForgableL2Txs)>maxL2Txs and nonForgableL2Txs have bigger fee than
forgableL2Txs, the forgableTxs where never forged, neither the
nonForgableTxs. Now, the TxSelector first forges the forgableTxs (which
are forgable for the initial state of the accounts (balances & nonces),
and then the nonForgableL2Txs, which may be unblocked once the forgable
ones have been processed.
New configuration Coordinator configuration parameter `ForgeOncePerSlotIfTxs`:
ForgeOncePerSlotIfTxs will make the coordinator forge at most one batch per
slot, only if there are included txs in that batch, or pending l1UserTxs in the
smart contract. Setting this parameter overrides `ForgeDelay`,
`ForgeNoTxsDelay`, `MustForgeAtSlotDeadline` and `IgnoreSlotCommitment`.
Also restructure a bit the functions that check policies to decide whether or
not to forge a batch.
- Add new command to the cli/node: `serveapi` that alows serving the API just
by connecting to the PostgreSQL database. The mode flag should me passed in
order to select whether we are connecting to a synchronizer database or a
coordinator database. If `coord` is chosen as mode, the coordinator
endpoints can be activated in order to allow inserting l2txs and
authorizations into the L2DB.
Summary of the implementation details
- New SQL table with 3 columns (plus `item_id` pk). The table only contains a
single row with `item_id` = 1. Columns:
- state: historydb.StateAPI in JSON. This is the struct that is served via
the `/state` API endpoint. The node will periodically update this struct
and store it int he DB. The api server will query it from the DB to
serve it.
- config: historydb.NodeConfig in JSON. This struct contains node
configuration parameters that the API needs to be aware of. It's updated
once every time the node starts.
- constants: historydb.Constants in JSON. This struct contains all the
hermez network constants gathered via the ethereum client by the node.
It's written once every time the node starts.
- The HistoryDB contains methods to get and update each one of these columns
individually.
- The HistoryDB contains all methods that query the DB and prepare objects that
will appear in the StateAPI endpoint.
- The configuration used in for the `serveapi` cli/node command is defined in
`config.APIServer`, and is a subset of `node.Config` in order to allow
reusing the same configuration file of the node if desired.
- A new object is introduced in the api: `StateAPIUpdater`, which contains all
the necessary information to update the StateAPI in the DB periodically by
the node.
- Moved the types `SCConsts`, `SCVariables` and `SCVariablesPtr` from
`syncrhonizer` to `common` for convenience.
Update to last Poseidon (go-iden3-crypto) & go-merkletree versions,
update the affected test vectors, and check ZKInputs compatibility with
last version of circuits.
Update to last Poseidon version (which includes the changes of the
reference implementation from
26ddaa91db)
Compatible with update at circomlib
