		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_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.

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

		unsigned int	flags,
		bool	cacheSigStore,
		bool	cacheFullScriptStore,
		PrecomputedTransactionData &	txdata,
		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.

◆ PRUNE_LOCK_BUFFER

constexpr int PRUNE_LOCK_BUFFER {10}

staticconstexpr
