 Redo coordinator structure, connect API to node
- API:
- Modify the constructor so that hardcoded rollup constants don't need
to be passed (introduce a `Config` and use `configAPI` internally)
- Common:
- Update rollup constants with proper *big.Int when required
- Add BidCoordinator and Slot structs used by the HistoryDB and
Synchronizer.
- Add helper methods to AuctionConstants
- AuctionVariables: Add column `DefaultSlotSetBidSlotNum` (in the SQL
table: `default_slot_set_bid_slot_num`), which indicates at which
slotNum does the `DefaultSlotSetBid` specified starts applying.
- Config:
- Move coordinator exclusive configuration from the node config to the
coordinator config
- Coordinator:
- Reorganize the code towards having the goroutines started and stopped
from the coordinator itself instead of the node.
- Remove all stop and stopped channels, and use context.Context and
sync.WaitGroup instead.
- Remove BatchInfo setters and assing variables directly
- In ServerProof and ServerProofPool use context instead stop channel.
- Use message passing to notify the coordinator about sync updates and
reorgs
- Introduce the Pipeline, which can be started and stopped by the
Coordinator
- Introduce the TxManager, which manages ethereum transactions (the
TxManager is also in charge of making the forge call to the rollup
smart contract). The TxManager keeps ethereum transactions and:
1. Waits for the transaction to be accepted
2. Waits for the transaction to be confirmed for N blocks
- In forge logic, first prepare a batch and then wait for an available
server proof to have all work ready once the proof server is ready.
- Remove the `isForgeSequence` method which was querying the smart
contract, and instead use notifications sent by the Synchronizer to
figure out if it's forging time.
- Update test (which is a minimal test to manually see if the
coordinator starts)
- HistoryDB:
- Add method to get the number of batches in a slot (used to detect when
a slot has passed the bid winner forging deadline)
- Add method to get the best bid and associated coordinator of a slot
(used to detect the forgerAddress that can forge the slot)
- General:
- Rename some instances of `currentBlock` to `lastBlock` to be more
clear.
- Node:
- Connect the API to the node and call the methods to update cached
state when the sync advances blocks.
- Call methods to update Coordinator state when the sync advances blocks
and finds reorgs.
- Synchronizer:
- Add Auction field in the Stats, which contain the current slot with
info about highest bidder and other related info required to know who
can forge in the current block.
- Better organization of cached state:
- On Sync, update the internal cached state
- On Init or Reorg, load the state from HistoryDB into the
internal cached state.
