With this commit we add more specific assertions to our PSBT signing
test in order to make sure change outputs have the proper PSBT metadata
associated with them, depending on their address type.
This commit adds a deleteSessionFromTower method which can be used to
dial the tower that we created a given session with and then sends that
tower the DeleteSession method.
In this commit, a thread-safe min-heap is implemented. It will carry
sessionCloseItems which carry a sessionID and a block height at which
the session should be closed.
This commit adds a new ListClosableSessions method to the tower client
DB. This method will return a map of sessionIDs to block heights. The
IDs belong to sessions that are considered closable and the block
heights are the block height at which the last associated channel for
the session was closed in.
This commit adds a `MarkChannelClosed` method to the tower client DB.
This function can be called when a channel is closed and it will
check the channel's associated sessions to see if any of them are
"closable". Any closable sessions are added to a new
`cClosableSessionsBkt` bucket so that they can be evaluated in future.
Note that only the logic for this function is added in this commit and
it is not yet called.
In this commit, a migration is added that adds an index from channel to
sessionIDs (using the DB-assigned session IDs). This will make it easier
in future to know which sessions have updates for which channels.
In this commit, a new session-ID index is added to the tower client db
with the help of a migration. This index holds a mapping from a
db-assigned-ID (a uint64 encoded using BigSize encoding) to real session
ID (33 bytes). This mapping will help us save space in future when
persisting references to sessions.
Add a new test htlc set comprised of htlc 1 from the original set and
two new htlcs, 5 and 6, that use the same preimage and have the same
output value (in sats). This htlc set is used in tests that assert the
ordering of htlcs that have the same preimage and output value.
In this commit, an assertion is added to the bolt 3 commitment tx tests
that ensures that the local and remote balances add up to the expected
funding amount. Adding this assertion uncovered a borked test vector
which is also fixed in this commit.
Prior to this commit, the wtclient would request tower info from both
the legacy client and the anchors client and would then merge the
results returned. This is incorrect since the two clients will have
different session info and different "active" statuses for the same
tower. This commit thus ensures that we dont lose this info.
In this commit, a new ClientSessionFilterFn parameter is added to the
DB's ListClientSession method which can be used to allow the caller to
specify a filter function for filtering sessions read from the DB.
Currently all filtering of sessions are done after the sessions have
been read from the DB, so adding this option should provide some
efficiency.
This commit changes how the node's state is updated to make sure the
test cleans up the node's state.
Also `testLookupHtlcResolution` is fixed with a cleanup.
