Update coordinator, call all api update functions - Common: - Rename Block.EthBlockNum to Block.Num to avoid unneeded repetition - API: - Add UpdateNetworkInfoBlock to update just block information, to be used when the node is not yet synchronized - Node: - Call API.UpdateMetrics and UpdateRecommendedFee in a loop, with configurable time intervals - Synchronizer: - When mapping events by TxHash, use an array to support the possibility of multiple calls of the same function happening in the same transaction (for example, a smart contract in a single transaction could call withdraw with delay twice, which would generate 2 withdraw events, and 2 deposit events). - In Stats, keep entire LastBlock instead of just the blockNum - In Stats, add lastL1BatchBlock - Test Stats and SCVars - Coordinator: - Enable writing the BatchInfo in every step of the pipeline to disk (with JSON text files) for debugging purposes. - Move the Pipeline functionality from the Coordinator to its own struct (Pipeline) - Implement shouldL1lL2Batch - In TxManager, implement logic to perform several attempts when doing ethereum node RPC calls before considering the error. (Both for calls to forgeBatch and transaction receipt) - In TxManager, reorganize the flow and note the specific points in which actions are made when err != nil - HistoryDB: - Implement GetLastL1BatchBlockNum: returns the blockNum of the latest forged l1Batch, to help the coordinator decide when to forge an L1Batch. - EthereumClient and test.Client: - Update EthBlockByNumber to return the last block when the passed number is -1.

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.

Update coordinator to work better under real net - 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.

Update coordinator, call all api update functions - Common: - Rename Block.EthBlockNum to Block.Num to avoid unneeded repetition - API: - Add UpdateNetworkInfoBlock to update just block information, to be used when the node is not yet synchronized - Node: - Call API.UpdateMetrics and UpdateRecommendedFee in a loop, with configurable time intervals - Synchronizer: - When mapping events by TxHash, use an array to support the possibility of multiple calls of the same function happening in the same transaction (for example, a smart contract in a single transaction could call withdraw with delay twice, which would generate 2 withdraw events, and 2 deposit events). - In Stats, keep entire LastBlock instead of just the blockNum - In Stats, add lastL1BatchBlock - Test Stats and SCVars - Coordinator: - Enable writing the BatchInfo in every step of the pipeline to disk (with JSON text files) for debugging purposes. - Move the Pipeline functionality from the Coordinator to its own struct (Pipeline) - Implement shouldL1lL2Batch - In TxManager, implement logic to perform several attempts when doing ethereum node RPC calls before considering the error.
