- 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.
Til (Test instructions language)
Language to define sets of instructions to simulate Hermez transactions (L1 & L2) with real data.
Syntax
Global
- Set type definition
- Blockchain: generate the transactions that would come from the Hermez smart contract on the blockchain.
Type: Blockchain- PoolL2: generate the transactions that would come from the Pool of L2Txs
Type: PoolL2
Blockchain set of instructions
Available instructions:
Type: Blockchain
// add the TokenID:
AddToken(1)
// deposit of TokenID=1, on the account of tokenID=1 for the user A, of an
// amount of 50 units
CreateAccountDeposit(1) A: 50
// create the account of TokenID=1 for the user B, deposit of TokenID=1, on the
// account of tokenID=1 for the user B, of an amount of 40 units and atomically
// transfer 10 units to account of tokenID=1 for the user A
CreateAccountDepositTransfer(1) B-A: 40, 10
// transaction generated by the Coordinator, create account for user User0 for
// the TokenID=2, with a deposit of 0
CreateAccountCoordinator(2) User0
// deposit of TokenID=1, at the account A, of 6 units
Deposit(1) A: 6
// deposit of TokenID=1, on the account of tokenID=1 for the user B, of an
// amount of 6 units and atomically transfer 10 units to account of tokenID=1 for
// the user A
DepositTransfer(1) B-A: 6, 4
// transfer of TokenID=1, from the account A to B (for that token), of 6 units,
// paying a fee of 3. Transaction will be a L2Tx
Transfer(1) A-B: 6 (3)
// exit of TokenID=1, from the account A (for that token), of 5 units, paying a
// fee of 1. Transaction will be a L2Tx
Exit(1) A: 5 (1)
// force-transfer of TokenID=1, from the account A to B (for that token), of 6
// units. Transaction will be L1UserTx of ForceTransfer type
ForceTransfer(1) A-B: 6
// force-exit of TokenID=1, from the account A (for that token), of 5 units.
// Transaction will be L1UserTx of ForceExit type
ForceExit(1) A: 5
// advance one batch, forging without L1UserTxs, only can contain L2Txs and
// L1CoordinatorTxs
> batch
// advance one batch, forging with L1UserTxs (and L2Txs and L1CoordinatorTxs)
> batchL1
// advance an ethereum block
> block
PoolL2 set of instructions
Available instructions:
Type: PoolL2
// transfer of TokenID=1, from the account A to B (for that token), of 6 units,
// paying a fee of 4
PoolTransfer(1) A-B: 6 (4)
// exit of TokenID=1, from the account A (for that token), of 3 units, paying a
// fee of 1
PoolExit(1) A: 3 (1)
Usage
// create a new til.Context
tc := til.NewContext(eth.RollupConstMaxL1UserTx)
// generate Blockchain blocks data from the common.SetBlockcahin0 instructions set
blocks, err = tc.GenerateBlocks(common.SetBlockchainMinimumFlow0)
assert.Nil(t, err)
// generate PoolL2 transactions data from the common.SetPool0 instructions set
poolL2Txs, err = tc.GeneratePoolL2Txs(common.SetPoolL2MinimumFlow0)
assert.Nil(t, err)
Where blocks will contain:
// BatchData contains the information of a Batch
type BatchData struct {
L1CoordinatorTxs []common.L1Tx
L2Txs []common.L2Tx
CreatedAccounts []common.Account
}
// BlockData contains the information of a Block
type BlockData struct {
L1UserTxs []common.L1Tx
Batches []BatchData
RegisteredTokens []common.Token
}
