Eduard S 3b99953007 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.

Test Ethclient - Contracts

Contracts

The first step is to clone the github repository where the contracts are located:

git clone https://github.com/hermeznetwork/contracts.git

While the prepared deployment is not found to master, branch in repository must be changed:

git checkout feature/ethclient-test-deployment-ganache (tested with commit f62c768bd4817921872666b3644403a119e28248)

Now, install the dependencies:

cd contracts/
yarn install

Go to where the deployment scripts for the test are found:

cd scripts/ethclient-deployment/

Now, in a terminal start a local blockchain with ganache:

../../node_modules/.bin/ganache-cli -d -m "explain tackle mirror kit van hammer degree position ginger unfair soup bonus" -p 8545 -l 12500000 -a 20 -e 10000 --allowUnlimitedContractSize --chainId 31337

Once ganache is ready, in another terminal run the deployment in the local ganache network:

npx buidler run --network ganache test-deployment.js

An output file necessary for the next step is obtained: deploy-output.

The files that appear in hermez-node/eth/contracts must be generated from the same contract that we deploy in this step

Ethclient Test

Different environment variables are necessary to run this test. They must be taken from the output file of the previous step.

They can be provided by file called .env:

GENESIS_BLOCK=97
AUCTION="0x5E0816F0f8bC560cB2B9e9C87187BeCac8c2021F"
AUCTION_TEST="0x56D4563E85477AC8Aa6a3b980b831DDb18a826ec"
TOKENHEZ="0x2b7dEe2CF60484325716A1c6A193519c8c3b19F3"
HERMEZ="0x6F4e99522F4eB37e0B73D0C0373147893EF12fD5"
WDELAYER="0x5D94e3e7aeC542aB0F9129B9a7BAdeb5B3Ca0f77"
WDELAYER_TEST="0xdc05EFc3029024068FCc86f05323411f14D69280"

An example is found in hermez-node/eth/.env.example

And then run test from hermez-node/eth/:

INTEGRATION=1 go test

Or they can be provided as a parameter in the command that runs the test:

INTEGRATION=1 GENESIS_BLOCK=97 AUCTION="0x5E0816F0f8bC560cB2B9e9C87187BeCac8c2021F" AUCTION_TEST="0x56D4563E85477AC8Aa6a3b980b831DDb18a826ec" TOKENHEZ="0x2b7dEe2CF60484325716A1c6A193519c8c3b19F3" HERMEZ="0x6F4e99522F4eB37e0B73D0C0373147893EF12fD5" WDELAYER="0x5D94e3e7aeC542aB0F9129B9a7BAdeb5B3Ca0f77" WDELAYER_TEST="0xdc05EFc3029024068FCc86f05323411f14D69280" go test
