Functions

func NewQueueingTxStrategy 

func NewQueueingTxStrategy(subject uuid.UUID, queueSize uint32, queryTimeout time.Duration) (strategy txmgrtypes.TxStrategy)

NewQueueingTxStrategy creates a new TxStrategy that drops the oldest transactions after the queue size is exceeded if a queue size is specified, and otherwise does not drop transactions.

func NewSendEveryStrategy 

func NewSendEveryStrategy() txmgrtypes.TxStrategy

NewSendEveryStrategy creates a new TxStrategy that does not drop transactions.

Types

type AbandonedTx added in v2.8.0 

type AbandonedTx[ADDR types.Hashable] struct {
	// contains filtered or unexported fields
}

AbandonedTx is a transaction who's 'FromAddress' was removed from the KeyStore(by the Node Operator). Thus, any new attempts for this Tx can't be signed/created. This means no fee bumping can be done. However, the Tx may still have live attempts in the chain's mempool, and could get confirmed on the chain as-is. Thus, the TXM should not directly discard this Tx.

type Broadcaster 

type Broadcaster[
	CHAIN_ID types.ID,
	HEAD types.Head[BLOCK_HASH],
	ADDR types.Hashable,
	TX_HASH types.Hashable,
	BLOCK_HASH types.Hashable,
	SEQ types.Sequence,
	FEE feetypes.Fee,
] struct {
	services.StateMachine

	txmgrtypes.TxAttemptBuilder[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, SEQ, FEE]
	// contains filtered or unexported fields
}

Broadcaster monitors txes for transactions that need to be broadcast, assigns sequences and ensures that at least one node somewhere has received the transaction successfully.

This does not guarantee delivery! A whole host of other things can subsequently go wrong such as transactions being evicted from the mempool, nodes going offline etc. Responsibility for ensuring eventual inclusion into the chain falls on the shoulders of the confirmer.

What Broadcaster does guarantee is: - a monotonic series of increasing sequences for txes that can all eventually be confirmed if you retry enough times - transition of txes out of unstarted into either fatal_error or unconfirmed - existence of a saved tx_attempt

type Confirmer 

type Confirmer[

}

Confirmer is a broad service which performs four different tasks in sequence on every new longest chain Step 1: Mark that all currently pending transaction attempts were broadcast before this block Step 2: Check pending transactions for receipts Step 3: See if any transactions have exceeded the gas bumping block threshold and, if so, bump them Step 4: Check confirmed transactions to make sure they are still in the longest chain (reorg protection)

func (*Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) CheckConfirmedMissingReceipt 

func (ec *Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) CheckConfirmedMissingReceipt(ctx context.Context) (err error)

CheckConfirmedMissingReceipt will attempt to re-send any transaction in the state of "confirmed_missing_receipt". If we get back any type of senderror other than "sequence too low" it means that this transaction isn't actually confirmed and needs to be put back into "unconfirmed" state, so that it can enter the gas bumping cycle. This is necessary in rare cases (e.g. Polygon) where network conditions are extremely hostile.

For example, assume the following scenario:

0. We are connected to multiple primary nodes via load balancer 1. We send a transaction, it is confirmed and, we get a receipt 2. A new head comes in from RPC node 1 indicating that this transaction was re-org'd, so we put it back into unconfirmed state 3. We re-send that transaction to a RPC node 2 **which hasn't caught up to this re-org yet** 4. RPC node 2 still has an old view of the chain, so it returns us "sequence too low" indicating "no problem this transaction is already mined" 5. Now the transaction is marked "confirmed_missing_receipt" but the latest chain does not actually include it 6. Now we are reliant on the Resender to propagate it, and this transaction will not be gas bumped, so in the event of gas spikes it could languish or even be evicted from the mempool and hold up the queue 7. Even if/when RPC node 2 catches up, the transaction is still stuck in state "confirmed_missing_receipt"

This scenario might sound unlikely but has been observed to happen multiple times in the wild on Polygon.

func (*Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) CheckForReceipts 

func (ec *Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) CheckForReceipts(ctx context.Context, blockNum int64) error

func (ec *Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) Close() error

func (*Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) EnsureConfirmedTransactionsInLongestChain 

func (ec *Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) EnsureConfirmedTransactionsInLongestChain(ctx context.Context, head types.Head[BLOCK_HASH]) error

EnsureConfirmedTransactionsInLongestChain finds all confirmed txes up to the depth of the given chain and ensures that every one has a receipt with a block hash that is in the given chain.

If any of the confirmed transactions does not have a receipt in the chain, it has been re-org'd out and will be rebroadcast.

func (*Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) FindTxsRequiringRebroadcast

FindTxsRequiringRebroadcast returns attempts that hit insufficient native tokens, and attempts that need bumping, in sequence ASC order

func (*Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) ForceRebroadcast 

func (ec *Confirmer[CHAIN_ID, HEAD, ADDR, TX_HASH, BLOCK_HASH, R, SEQ, FEE]) ForceRebroadcast(ctx context.Context, seqs []SEQ, fee FEE, address ADDR, overrideGasLimit uint64) error

ForceRebroadcast sends a transaction for every sequence in the given sequence range at the given gas price. If an tx exists for this sequence, we re-send the existing tx with the supplied parameters. If an tx doesn't exist for this sequence, we send a zero transaction. This operates completely orthogonal to the normal Confirmer and can result in untracked attempts! Only for emergency usage. This is in case of some unforeseen scenario where the node is refusing to release the lock. KISS.

Resender periodically picks up transactions that have been languishing unconfirmed for a configured amount of time without being sent, and sends their highest priced attempt again. This helps to defend against geth/parity silently dropping txes, or txes being ejected from the mempool.

Previously we relied on the bumper to do this for us implicitly but there can occasionally be problems with this (e.g. abnormally long block times, or if gas bumping is disabled)

type Tracker added in v2.8.0 

type Tracker[
	CHAIN_ID types.ID,
	ADDR types.Hashable,
	TX_HASH types.Hashable,
	BLOCK_HASH types.Hashable,
	R txmgrtypes.ChainReceipt[TX_HASH, BLOCK_HASH],
	SEQ types.Sequence,
	FEE feetypes.Fee,
] struct {
	services.StateMachine
	// contains filtered or unexported fields
}

Tracker tracks all transactions which have abandoned fromAddresses. The fromAddresses can be deleted by Node Operators from the KeyStore. In such cases, existing in-flight transactions for these fromAddresses are considered abandoned too. Since such Txs can still have attempts on chain's mempool, these could still be confirmed. This tracker just tracks such Txs for some time, in case they get confirmed as-is.
