Detailed Description

Validation result for a transaction evaluated by MemPoolAccept (single or package).

Here are the expected fields and properties of a result depending on its ResultType, applicable to results returned from package evaluation: +-----------------------—+--------—+----------------------------------------—+------------—+ | Field or property | VALID | INVALID | MEMPOOL_ENTRY | | | |----------------------------------------—| | | | | TX_PACKAGE_RECONSIDERABLE | Other | | +-----------------------—+--------—+------------------------—+------------—+------------—+ | txid in mempool? | yes | no | no* | yes | | m_state | IsValid() | IsInvalid() | IsInvalid() | IsValid() | | m_replaced_transactions | yes | no | no | no | | m_vsize | yes | no | no | yes | | m_base_fees | yes | no | no | yes | | m_effective_feerate | yes | yes | no | no | | m_txids_fee_calculations | yes | yes | no | no | +-----------------------—+--------—+------------------------—+------------—+------------—+ (*) Individual transaction acceptance doesn't return MEMPOOL_ENTRY. It returns INVALID, with the error txn-already-in-mempool. In this case, the txid may be in the mempool for a tx conflict (TX_AVALANCHE_RECONSIDERABLE).

Member Data Documentation

◆ m_base_fees

const std::optional<Amount> MempoolAcceptResult::m_base_fees

Raw base fees in satoshis.

Definition at line 228 of file validation.h.

◆ m_effective_feerate

const std::optional<CFeeRate> MempoolAcceptResult::m_effective_feerate

The feerate at which this transaction was considered.

This includes any fee delta added using prioritisetransaction (i.e. modified fees). If this transaction was submitted as a package, this is the package feerate, which may also include its descendants and/or ancestors (see m_txids_fee_calculations below).

Definition at line 236 of file validation.h.

◆ m_result_type

const ResultType MempoolAcceptResult::m_result_type

Result type.

Present in all MempoolAcceptResults.

Definition at line 217 of file validation.h.

◆ m_state

const TxValidationState MempoolAcceptResult::m_state

Contains information about why the transaction failed.

Definition at line 220 of file validation.h.

◆ m_txids_fee_calculations

const std::optional<std::vector<TxId> > MempoolAcceptResult::m_txids_fee_calculations

Contains the txids of the transactions used for fee-related checks.

Includes this transaction's txid and may include others if this transaction was validated as part of a package. This is not necessarily equivalent to the list of transactions passed to ProcessNewPackage().

Definition at line 243 of file validation.h.

◆ m_vsize

const std::optional<int64_t> MempoolAcceptResult::m_vsize

Virtual size as used by the mempool, calculated using serialized size and sigchecks.
