◆ CreateAndProcessBlock()

CBlock TestChain100Setup::CreateAndProcessBlock	(	const std::vector< CMutableTransaction > &	txns,
		const CScript &	scriptPubKey,
		Chainstate *	chainstate = `nullptr`
	)

Create a new block with just given transactions, coinbase paying to scriptPubKey, and try to add it to the current chain.

If no chainstate is specified, default to the active.

◆ CreateValidMempoolTransaction() [1/2]

CMutableTransaction TestChain100Setup::CreateValidMempoolTransaction	(	const std::vector< CTransactionRef > &	input_transactions,

		int	input_height,
		const std::vector< CKey > &	input_signing_keys,
		const std::vector< CTxOut > &	outputs,
		bool	submit = `true`
	)

Create a transaction and, optionally, submit to the mempool.

Parameters

input_transactions	The transactions to spend
inputs	Outpoints with which to construct transaction vin.
input_height	The height of the block that included the input transaction(s).
input_signing_keys	The keys to spend inputs.
outputs	Transaction vout.
submit	Whether or not to submit to mempool

		uint32_t	input_vout,
		int	input_height,
		CKey	input_signing_key,
		CScript	output_destination,
		CAmount	output_amount = `CAmount(1 * COIN)`,
		bool	submit = `true`
	)

Create a 1-in-1-out transaction and, optionally, submit to the mempool.

Parameters

input_transaction	The transaction to spend
input_vout	The vout to spend from the input_transaction
input_height	The height of the block that included the input_transaction
input_signing_key	The key to spend the input_transaction
output_destination	Where to send the output
output_amount	How much to send
submit	Whether or not to submit to mempool

Here is the call graph for this function:

◆ CreateValidTransaction()

std::pair< CMutableTransaction, CAmount > TestChain100Setup::CreateValidTransaction	(	const std::vector< CTransactionRef > &	input_transactions,
		const std::vector< COutPoint > &	inputs,
		int	input_height,

		const std::vector< CTxOut > &	outputs,
		const std::optional< CFeeRate > &	feerate,
		const std::optional< uint32_t > &	fee_output
	)

Create a transaction, optionally setting the fee based on the feerate.

Note: The feerate may not be met exactly depending on whether the signatures can have different sizes.

Parameters

input_transactions	The transactions to spend
inputs	Outpoints with which to construct transaction vin.
input_height	The height of the block that included the input transactions.
input_signing_keys	The keys to spend the input transactions.
outputs	Transaction vout.
feerate	The feerate the transaction should pay.
fee_output	The index of the output to take the fee from.

Returns: The transaction and the fee it pays

◆ mineBlocks()

void TestChain100Setup::mineBlocks ( int num_blocks )

Mine a series of new blocks on the active chain.

◆ PopulateMempool()

std::vector< CTransactionRef > TestChain100Setup::PopulateMempool	(	FastRandomContext &	det_rand,
		size_t	num_transactions,
		bool	submit
	)

Create transactions spending from m_coinbase_txns.

These transactions will only spend coins that exist in the current chain, but may be premature coinbase spends, have missing signatures, or violate some other consensus rules. They should only be used for testing mempool consistency. All transactions will have some random number of inputs and outputs (between 1 and 24). Transactions may or may not be dependent upon each other; if dependencies exit, every parent will always be somewhere in the list before the child so each transaction can be submitted in the same order they appear in the list.

Parameters

[in] submit When true, submit transactions to the mempool. When false, return them but don't submit them.

Returns: A vector of transactions that can be submitted to the mempool.
