		const CTransactionRef &	tx,
		int64_t	accept_time,
		bool	bypass_limits,
		bool	test_accept = `false`,
		unsigned int	heightOverride = `0`
	)

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_chainstate	Reference to the active chainstate.
[in]	tx	The transaction to submit for mempool acceptance.
[in]	accept_time	The timestamp for adding the transaction to the mempool. It is also used to determine when the entry expires.
[in]	bypass_limits	When true, don't enforce mempool fee and capacity limits.
[in]	test_accept	When true, run validation checks but don't submit to mempool.
[in]	heightOverride	Override the block height of the transaction. Used only upon reorg.

Returns: a MempoolAcceptResult indicating whether the transaction was accepted/rejected with reason.

◆ CalculateLockPointsAtTip()

std::optional< LockPoints > CalculateLockPointsAtTip	(	CBlockIndex *	tip,
		const CCoinsView &	coins_view,
		const CTransaction &	tx
	)

Calculate LockPoints required to check if transaction will be BIP68 final in the next block to be created on top of tip.

Parameters

[in]	tip	Chain tip for which tx sequence locks are calculated. For example, the tip of the current active chain.
[in]	coins_view	Any CCoinsView that provides access to the relevant coins for checking sequence locks. For example, it can be a CCoinsViewCache that isn't connected to anything but contains all the relevant coins, or a CCoinsViewMemPool that is connected to the mempool and chainstate UTXO set. In the latter case, the caller is responsible for holding the appropriate locks to ensure that calls to GetCoin() return correct coins.
[in]	tx	The transaction being evaluated.

Returns: The resulting height and time calculated and the hash of the block needed for calculation, or std::nullopt if there is an error.

Return true if the provided block header is valid.

Only verify PoW if blockValidationOptions is configured to do so. This allows validation of headers on which the PoW hasn't been done. For example: to validate template handed to mining software. Do not call this for any check that depends on the context. For context-dependent calls, see ContextualCheckBlockHeader.

◆ CheckInputScripts() [1/2]

bool CheckInputScripts	(	const CTransaction &	tx,
		TxValidationState &	state,
		const CCoinsViewCache &	view,
		const uint32_t	flags,
		bool	sigCacheStore,
		bool	scriptCacheStore,
		const PrecomputedTransactionData &	txdata,
		int &	nSigChecksOut,
		TxSigCheckLimiter &	txLimitSigChecks,
		CheckInputsLimiter *	pBlockLimitSigChecks,
		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.

Upon success nSigChecksOut will be filled in with either:

correct total for all inputs, or,
0, in the case when checks were pushed onto pvChecks (i.e., a cache miss with pvChecks non-null), in which case the total can be found by executing pvChecks and adding the results.

Setting sigCacheStore/scriptCacheStore 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.

pLimitSigChecks can be passed to limit the sigchecks count either in parallel or serial validation. With pvChecks null (serial validation), breaking the pLimitSigChecks limit will abort evaluation early and return false. With pvChecks not-null (parallel validation): the cached nSigChecks may itself break the limit in which case false is returned, OR, each entry in the returned pvChecks must be executed exactly once in order to probe the limit accurately.

Parameters

[in]	tip	Chain tip to check tx sequence locks against. For example, the tip of the current active chain.
