The cause was that converting a block number to an scid truncates it
at 24 bits. When we look through the index from (truncated number) to
(real end number) we get every channel, which is too large to encode,
so we iterate again.
This fixes both that problem, and also the issue that we'd end up
dividing into many empty sections until we get to the highest block
number. Instead, we just tack the empty blocks on to then end of the
final query.
(My initial version requested 0xFFFFFFFE blocks, but the dev code
which records what blocks were returned can't make a bitmap that big
on 32 bit).

onchaind: allow multiple candidate HTLCs for output match
When we have multiple HTLCs with the same preimage and the same CLTV,
it doesn't matter what order we treat them (they're literally
identical). But when we offer HTLCs with the same preimage but
different CLTVs, the commitment tx outputs look identical, but the
HTLC txs are different: if we simply take the first HTLC which matches
(and that's not the right one), the HTLC signature we got from them
won't match. As we rely on the signature matching to detect the fee
paid, we get:
onchaind: STATUS_FAIL_INTERNAL_ERROR: grind_fee failed
So we alter match_htlc_output() to return an array of all matching
HTLC indices, which can have more than one entry for offered HTLCs.
If it's our commitment, we loop through until one of the HTLC
signatures matches. If it's their commitment, we choose the HTLC with
the largest CLTV: we're going to ignore it once that hits anyway, so
this is the most conservative approach. If it's a penalty, it doesn't
matter since we steal all HTLC outputs the same independent of CLTV.
For accepted HTLCs, the CLTV value is encoded in the witness script,
so this confusion isn't possible. We nonetheless assert that the
CLTVs all match in that case.

2018-07-29 03:53:53 +02:00
### Added
- Protocol: gossipd now deliberately delays spamming with `channel_update` .
2018-08-09 04:53:18 +02:00

failures and reduces forced closures.

- Protocol: `option_data_loss_protect` now supported to protect peers
against being out-of-date.

TORv2, TORv3).

`man` command.

to/from peers, instead of `gossipd` doing that itself. `lightning_openingd` now

their capacity or their `htlc_minimum_msat` parameter (#1777)
2018-08-09 02:27:30 +02:00
- We now try to connect to all known addresses for a peer, not just
the one given or the first one announced.
2018-08-22 13:17:20 +02:00
- Crash logs are now placed one-per file like `crash.log.20180822233752`
2018-08-24 04:22:02 +02:00
- We will no longer allow withdrawing funds or funding channels if we
2018-08-28 22:46:36 +02:00
do not have a fee estimate (eg. bitcoind not synced); use new `feerate` arg.
2018-08-09 02:25:30 +02:00
2018-07-29 03:53:53 +02:00
### Deprecated
### Removed
- JSON API: `listpeers` results no long have `alias` and `color` fields;
they're in `listnodes` (we used to internally merge the information).
2018-08-09 02:25:30 +02:00
- JSON API: `listpeers` will never have `state` field (it accidentally
used to exist and set to `GOSSIPING` before we opened a channel).
`connected` will indicate if we're connected, and the `channels`
array indicates individual channel states (if any).
2018-08-28 22:46:36 +02:00
- Config: `default-fee-rate` is no longer available; use explicit `feerate`
option if necessary.
2018-07-29 04:08:29 +02:00
- Removed all Deprecated options from 0.6.
2018-07-29 03:53:53 +02:00
### Fixed
- Protocol: `node_announcement` multiple addresses are correctly ordered and uniquified.
2018-08-25 02:33:35 +02:00
- Protocol: if we can't estimate feerate, be almost infinitely
tolerant of other side setting fees to avoid unilateral close.
2018-07-29 03:53:53 +02:00
- JSON API: `listnodes` : now displays node aliases and colors even if they
don't advertise a network address
2018-07-29 07:51:38 +02:00
- JSON API: `fundchannel all` : now restricts to 2^24-1 satoshis rather than failing.
2018-08-25 02:33:35 +02:00
- JSON API: `listnodes` : now correctly prints `addresses` if more than
one is advertised.
- Config: `bind-addr` of a publicly accessible network address was announced.
2018-07-29 03:53:53 +02:00
- When we reconnect and have to retransmit failing HTLCs, the errors weren't
encrypted by us.
- `lightningd_config` man page is now installed by `make install` .
- Fixed crash when shutting down during opening a channel (#1737)
- Don't lose track of our own output when applying penalty transaction (#1738)
- Protocol: `channel_update` inside error messages now refers to correct channel.
2018-07-30 18:01:34 +02:00
- Stripping type prefix from `channel_update` s that are nested in an onion reply
to be compatible with eclair and lnd (#1730).
2018-08-01 16:17:36 +02:00
- Failing tests no longer delete the test directory, to allow easier debugging
(Issue: #1599 )
