Previously returned RPC_INTERNAL_ERROR. - `pruneblockchain` now returns RPC_MISC_ERROR if the blocks cannot be pruned because the node is not in pruned mode. Previously returned RPC_METHOD_NOT_FOUND. - `pruneblockchain` now returns RPC_INVALID_PARAMETER if the blocks cannot be pruned because the supplied timestamp is too late. Previously returned RPC_INTERNAL_ERROR. - `pruneblockchain` now returns RPC_MISC_ERROR if the blocks cannot be pruned because the blockchain is too short. Previously returned RPC_INTERNAL_ERROR. - `setban` now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the supplied IP address or subnet is invalid. Previously returned RPC_CLIENT_NODE_ALREADY_ADDED. - `setban` now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the user tries to unban a node that has not previously been banned. Previously returned RPC_MISC_ERROR. - `removeprunedfunds` now returns RPC_WALLET_ERROR if bitcoind is unable to remove the transaction. Previously returned RPC_INTERNAL_ERROR. - `removeprunedfunds` now returns RPC_INVALID_PARAMETER if the transaction does not exist in the wallet. Previously returned RPC_INTERNAL_ERROR. - `fundrawtransaction` now returns RPC_INVALID_ADDRESS_OR_KEY if an invalid change address is provided. Previously returned RPC_INVALID_PARAMETER. - `fundrawtransaction` now returns RPC_WALLET_ERROR if bitcoind is unable to create the transaction. The error message provides further details. Previously returned RPC_INTERNAL_ERROR. - The `gettxoutsetinfo` response now contains `disk_size` and `bogosize` instead of `bytes_serialized`. The first is a more accurate estimate of actual disk usage, but is not deterministic. The second is unrelated to disk usage, but is a database-independent metric of UTXO set size: it counts every UTXO entry as 50 + the length of its scriptPubKey. Reserve block space for high priority transactions (D485) --------------------------------------------------------- By default reserve 5% of the max generated block size parameter to hiprio transactions. Hence a `bitcoind` instance running with an unmodified configuration will reserve 100K for high priority transactions. The parameter name used for this configuration `blockprioritypercentage`. While introducing this new parameter we deprecated `blockprioritysize`(it was used to specify the amount of high prio reserved area in byte). A transaction is considered high priority if its priority is higher than this threshold: `COIN * 144 / 250`, where COIN is the value of a one bitcoin UTXO expressed in satoshis. Thus a transaction who as an input of 1 bitcoin and are 144 blocks old and whose size is 250 bytes is considered the priority cut-off.
