SomberNight	b1f606eaed	lnchannel: start using "latest" and "next" instead of "current" and "pending" ... "current" used to be "oldest_unrevoked"; and pending was "oldest_unrevoked + 1" but this was very confusing... so now we have "oldest_unrevoked", "latest", and "next" where "next" is "latest + 1" "oldest_unrevoked" and "latest" are either the same or are offset by 1 (but caller should know which one they need) rm "got_sig_for_next" - it was a redundant sanity check, that really just complicated things rm "local_commitment", "remote_commitment", "set_local_commitment", "set_remote_commitment" - just use "get_latest_commitment" instead	2019-08-20 09:03:12 +02:00

ThomasV	a8ce8109be	Perform breach remedy without sweepstore: ... - 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	2019-08-20 09:03:12 +02:00
ThomasV	f2d58d0e3f	optimize channel_db: ... - use python objects mirrored by sql database - write sql to file asynchronously - the sql decorator is awaited in sweepstore, not in channel_db	2019-08-20 09:03:12 +02:00

ThomasV	6bbdbf7596	rework on_channel_closed in LNWorker: ... - use detect_who_closed; this allows us to redeem to_remote of breach ctx - do not redeem to_local of breach ctx, because it is redundant with lnwatcher - rename a few methods	2019-08-20 09:03:11 +02:00

SomberNight	7292da24e6	lnchannel: only consider payments finished when we revoke our old ctx ... in the old code, `self.hm.received_in_ctn(self.config[REMOTE].ctn + 1)` did not really make sense as "received_in_ctn" compares the argument against the LOCAL ctn	2019-08-20 09:03:11 +02:00
