Function Documentation

check_estimates()

def smartfees.check_estimates	(		node,
			fees_seen,
			max_invalid,
			print_estimates = True
	)

This function calls estimatefee and verifies that the estimates
meet certain invariants.

small_txpuzzle_randfee()

def smartfees.small_txpuzzle_randfee	(		from_node,
			conflist,
			unconflist,
			amount,
			min_fee,
			fee_increment
	)

Create and send a transaction with a random fee.
The transaction pays to a trivial P2SH script, and assumes that its inputs
are of the same form.
The function takes a list of confirmed outputs and unconfirmed outputs
and attempts to use the confirmed list first for its inputs.
It adds the newly created outputs to the unconfirmed list.
Returns (raw transaction, fee)

split_inputs()

def smartfees.split_inputs	(		from_node,
			txins,
			txouts,
			initial_split = False
	)

We need to generate a lot of very small inputs so we can generate a ton of transactions
and they will have low priority.
This function takes an input from txins, and creates and sends a transaction
which splits the value into 2 outputs which are appended to txouts.

swap_outputs_in_rawtx()

def smartfees.swap_outputs_in_rawtx	(		rawtx,
			outputs,
			inputnum
	)

Since dictionaries in python are unsorted make sure that our outputs are correctly ordered.
Note: comparing strings to get "correct order" is based on the fact that
P2SH_1 string is < P2SH_2 string in this particular case.
