Instead of having in-memory access to the list of private keys
associated with a channel, we should have a generic API which
allows us to request signing, allowing the user to store private
keys any way they like.
The first step is the (rather mechanical) process of templating
the entire tree of ChannelManager -> Channel impls by the
key-providing type. In a later commit we should expose only public
keys where possible.
A pending claim request may contain a set of multiple outpoints.
If one or multiple of them get claimed by remote party, our in-flight
claiming transactions aren't valid anymore so we need to react
quickly and regenerate claiming transaction with accurate set.
However, a claimed outpoint may be disconnected and we need to resurrect
back outpoint among set of orignal pending claim request.
To guarantee consistency of contentious claimed outpoint we cache it
as OnchainEvent::ContentionsOutpoint and only delete it after
ANTI_REORG_DELAY.
Fix test broken by change, partial claiming on revoked txn
force us to regenerate txn
Because filter_block takes a and returns a list of s , we must add a lifetime to the ChainWatchInterface, which bubbles up in a lot of places. These places include adding a lifetime to the Node struct, which causes a lot of rearranging tests so that variables don't go out of scope before the Node that owns them does.
Adding this struct will allow us to remove the circular reference
between ChainListeners and the ChainWatchInterface, because it
separates out the responsibility of notifying listeners about new
blocks from the responsibility of storing and retrieving watched
transactions.
This includes the purpose of this PR, which is to remove the circular reference created by ChainListeners self-adding themselves to their ChainWatchInterface's `listeners` field.
