◆ AcceptToMemoryPool()

MempoolAcceptResult AcceptToMemoryPool ( Chainstate active_chainstate,
const CTransactionRef tx,
int64_t  accept_time,
bool  bypass_limits,
bool  test_accept 
)

Try to add a transaction to the mempool.

This is an internal function and is exposed only for testing. Client code should use ChainstateManager::ProcessTransaction()

Parameters
[in]active_chainstateReference to the active chainstate.
[in]txThe transaction to submit for mempool acceptance.
[in]accept_timeThe timestamp for adding the transaction to the mempool. It is also used to determine when the entry expires.
[in]bypass_limitsWhen true, don't enforce mempool fee and capacity limits, and set entry_sequence to zero.
[in]test_acceptWhen true, run validation checks but don't submit to mempool.
Returns
a MempoolAcceptResult indicating whether the transaction was accepted/rejected with reason.

◆ CheckInputScripts() [1/2]

bool CheckInputScripts ( const CTransaction tx,
TxValidationState state,
const CCoinsViewCache inputs,
unsigned int  flags,
bool  cacheSigStore,
bool  cacheFullScriptStore,
PrecomputedTransactionData txdata,
ValidationCache validation_cache,
std::vector< CScriptCheck > *  pvChecks 
)

Check whether all of this transaction's input scripts succeed.

This involves ECDSA signature checks so can be computationally intensive. This function should only be called after the cheap sanity checks in CheckTxInputs passed.

If pvChecks is not nullptr, script checks are pushed onto it instead of being performed inline. Any script checks which are not necessary (eg due to script execution cache hits) are, obviously, not pushed onto pvChecks/run.

Setting cacheSigStore/cacheFullScriptStore to false will remove elements from the corresponding cache which are matched. This is useful for checking blocks where we will likely never need the cache entry again.

Note that we may set state.reason to NOT_STANDARD for extra soft-fork flags in flags, block-checking callers should probably reset it to CONSENSUS in such cases.

Parameters
[in]tipChain tip to check tx sequence locks against. For example, the tip of the current active chain.
[in]lock_pointsLockPoints containing the height and time at which this transaction is final. Simulates calling SequenceLocks() with data from the tip passed in. The LockPoints should not be considered valid if CheckSequenceLocksAtTip returns false.

static

CheckWitnessMalleation performs checks for block malleation with regard to its witnesses.

Note: If the witness commitment is expected (i.e. expect_witness_commitment = true), then the block is required to have at least one transaction and the first transaction needs to have at least one input.

Context-dependent validity checks.
