Replay un-acked local updates (including commitment_signed) byte-for-byte.
If we have sent them a commitment signature that they "lost" (due to disconnect),
we need to make sure we replay the same local updates, as otherwise they could
end up with two (or more) signed valid commitment transactions at the same ctn.
Multiple valid ctxs at the same ctn is a major headache for pre-signing spending txns,
e.g. for watchtowers, hence we must ensure these ctxs coincide.
- remove remote_commitment_to_be_revoked
- pass old ctns to lnsweep.create_sweeptxs_for_watchtower
- store the ctn of sweeptxs in sweepStore database
- request the highest ctn from sweepstore using get_ctn
- send sweeptxs asynchronously in LNWallet.sync_with_watchtower
- add functions to lnsweep
- lnworker: analyze candidate ctx and htlc_tx
- watchtower will be optional
- add test for breach remedy with spent htlcs
- save tx name as label
main_loop should dump traces of unexpected exceptions to log.
Coroutines/functions invoked inside main_loop should simply propagate it
up the chain.
Typical exceptions are handled in handle_disconnect without dumping the trace.
- fix bug in lnsweep: lnwatcher transactions were indexed by prev_txid
- add test for breach remedy with unsettled htlcs
- add timeout option to lnpay, and replace DO_NOT_SETTLE with SETTLE_DELAY
so that we can read intermediate commitment tx in regtest
- send data_loss_protect fields with channel_reestablish
- close connection if we receive an unknown channel_reestablish
- log all exceptions that make us close a connection
- formatting
- use gossip_queries_req instead of initial_routing_sync
- add connected nodes to recent peers only after successful init
- derive timestamp used with gossip_timestamp_filter from channel_db
- fix query_short_channel_ids:
1. channel IDs must be sorted with zlib
2. limit request to 100
3. do not abuse this to request node_announcements; it is fine not to have all nodes.
- fix get_recent_peers:
1. do not set last_connected_date to 'now' if we never connected a node
2. sql query was misconstructed and was returning only one peer
- populate FALLBACK_NODE_LIST_MAINNET with nodes that have the requested flags
