AnalyzePSBT()

PSBTAnalysis node::AnalyzePSBT

ApplyHash() [1/3]

static void node::ApplyHash ( CHashWriter &  ss, const uint256 &  hash, const std::map< uint32_t, Coin > &  outputs  )

static

Warning: be very careful when changing this! assumeutxo and UTXO snapshot validation commitments are reliant on the hash constructed by this function.

If the construction of this hash is changed, it will invalidate existing UTXO snapshots. This will not result in any kind of consensus failure, but it will force clients that were expecting to make use of assumeutxo to do traditional IBD instead.

It is also possible, though very unlikely, that a change in this construction could cause a previously invalid (and potentially malicious) UTXO snapshot to be considered valid.

		CTransactionRef	tx,
		std::string &	err_string,
		const CAmount &	max_tx_fee,
		bool	relay,
		bool	wait_callback
	)

Submit a transaction to the mempool and (optionally) relay it to all P2P peers.

Mempool submission can be synchronous (will await mempool entry notification over the CValidationInterface) or asynchronous (will submit and not wait for notification), depending on the value of wait_callback. wait_callback MUST NOT be set while cs_main, cs_mempool or cs_wallet are held to avoid deadlock.

Parameters

[in]	node	reference to node context
[in]	tx	the transaction to broadcast
[out]	err_string	reference to std::string to fill with error string if available
[in]	max_tx_fee	reject txs with fees higher than this (if 0, accept any fee)
[in]	relay	flag if both mempool insertion and p2p relay are requested
[in]	wait_callback	wait until callbacks have been processed to avoid stale result due to a sequentially RPC. return error

Return transaction with a given hash.

If mempool is provided and block_index is not provided, check it first for the tx. If -txindex is available, check it next for the tx. Finally, if block_index is provided, check for tx by reading entire block from disk.

Parameters

[in]	block_index	The block to read from disk, or nullptr
[in]	mempool	If provided, check mempool for tx
[in]	hash	The txid
[in]	consensusParams	The params
[out]	hashBlock	The block hash, if the tx was found via -txindex or block_index

Returns

This sequence can have 4 types of outcomes:

1. Success
2. Shutdown requested
   • nothing failed but a shutdown was triggered in the middle of the sequence
3. Soft failure
   • a failure that might be recovered from with a reindex
4. Hard failure
   • a failure that definitively cannot be recovered from with a reindex

Currently, LoadChainstate returns a std::optional<ChainstateLoadingError> which:

• if has_value()

  • Either "Soft failure", "Hard failure", or "Shutdown requested", differentiable by the specific enumerator.

    Note that a return value of SHUTDOWN_PROBED means ONLY that "during this sequence, when we explicitly checked shutdown_requested() at arbitrary points, one of those calls returned true". Therefore, a return value other than SHUTDOWN_PROBED does not guarantee that shutdown hasn't been called indirectly.

• else
  • Success!
