2 weeks agorename pay_parameters for no amount invoice
Vincenzo Palazzo [Tue, 5 Nov 2024 11:45:01 +0000 (12:45 +0100)]
rename pay_parameters for no amount invoice

This commit renames the function `pay_parameters_for_zero_amount_invoice`
to `pay_parameters_for_variable_amount_invoice`.

The term "variable amount" is used to align with
the naming convention in the LDK node, helping to avoid
confusion between similar packages.

Clean up `PackageTemplate::get_height_timer` to consider type

`PackageTemplate::get_height_timer` is used to decide when to next
bump our feerate on claims which need to make it on chain within
some window. It does so by comparing the current height with some
deadline and increasing the bump rate as the deadline approaches.

However, the deadline used is the `counterparty_spendable_height`,
which is the height at which the counterparty might be able to
spend the same output, irrespective of why. This doesn't make sense
for all output types, for example outbound HTLCs are spendable by
our counteraprty immediately (by revealing the preimage), but we
don't need to get our HTLC timeout claims confirmed immedaitely,
as we actually have `MIN_CLTV_EXPIRY` blocks before the inbound
edge of a forwarded HTLC becomes claimable by our (other)
counterparty.

Thus, here, we adapt `get_height_timer` to look at the type of
output being claimed, and adjust the rate at which we bump the fee
according to the real deadline.

Fix `synchronize_listeners` calling default implementation

Previously, the `ChainListenerSet` `Listen` implementation wouldn't
forward to the listeners `block_connected` implementation outside of
tests. This would result in the default implementation of
`Listen::block_connected` being used and the listeners implementation
never being called.
