First, how we record "our_funds" and then apply pushes vs lease_fees
(for liquidity ad buys/sales) was exactly opposite.
For pushes we were reporting the total funded into the channel, with the
push representing how much we'd later moved to the peer.
For lease_fees we were rerporting the total in the channel, with the
push representing how much was already moved to the peer.
We fix this (from a view perspective) by re-adding lease fees to what's
reported in the channel funding totals. Since this is now new behavior
(for leased channel values), we added new fields so we can take the old
field names thru a deprecation cycle.
We also make it possible to differentiate btw a push and a lease_fee
(before they were all the same), by adding to new fields to `listpeers`:
`fee_paid_msat` and `fee_rcvd_msat`.
This allows us to avoid math in the bookkeeper, instead we just pick
the numbers out directly and record them.
Fixes#5472
Changelog-Added: JSON-RPC: `listpeers` now has a few new fields for `funding` (`remote_funds_msat`, `local_funds_msat`, `fee_paid_msat`, `fee_rcvd_msat`).
Changelog-Deprecated: JSON-RPC: `listpeers`.`funded` fields `local_msat` and `remote_msat` are now deprecated.

We used to tell connectd to remember our connect delay, and hand it
back (increased if necessary).
Instead, simply record when we last tried to connect. If it was less
than 10 minutes ago, double delay (up to 5 minutes max), otherwise
reset delay to 1 second.
This covers all scenarios: whether we reconnect then immediately
disconnect, or never successfully connect, it doesn't matter.

Fixes: #5453
Keep the accounts as an 'append only' log, instead we move the marker
for the 'channel_open' forward when a 'channel_open' comes out.
We also neatly hide the 'channel_proposed' events in 'inspect' if
there's a 'channel_open' for that same event.
If you call inspect before the 'channel_open' is confirmed, you'll see
the tag as 'channel_proposed', afterwards it shows up as
'channel_open'. However the event log rolls forward -- listaccountevents
will show the correct history of the proposal then open confirming (plus
any routing that happened before the channel confirmed).
We need a record of the channel account before you start sending
payments through it. Normally we don't start allowing payments to be
sent until after the channel has locked in but zeroconf does away with
this assumption.
Instead we push out a "channel_proposed" event, which should only show
up for zeroconfs.
First off, when we pull data out of JSON, unescape it so we don't end up
with extraneous escapes in our bookkeeping data. I promise, it's worth
it.
Then, when we print descriptions out to the csvs, we gotta wrap
everything in quotes... but also we have to change all the double-quotes
to singles so that adding the quotes doesn't do anything untoward.
We also just pass it thru json_escape to get rid of linebreaks etc.
Note that in the tests we do a byte comparison instead of converting the
CSV dumps to strings because python will escape the strings on
conversion...
So we print out invoice fees on the same line for those CSVs! This means
we have to do a little bit of gymnastics (but not too bad):
- we save the fee amount onto the income event now so we can use
it later
- we ignore every "invoice_fee" event for the koinly/cointracker
Note that since we're not skipping income events in the loops we also
move the newline character to the start of every `_entry` function so
skipped records dont incur empth lines.
Changelog-Added: bkpr: print out invoice fees on the same line for `koinly` and `cointracker` csv types
If we expect further events for an onchain output (because we can steal
it away from the 'external'/rightful owner), we mark them.
This prevents us from marking a channel as 'onchain-resolved' before
all events that we're interested in have actually hit the chain.
Case that this matters:
Peer publishes a (cheating) unilateral close and a timeout htlc (which
we can steal).
We then steal the timeout htlc.
W/o the stealable flag, we'd have marked the channel as resolved when
the peer published the timeout htlc, which is incorrect as we're still
waiting for the resolution of that timeout htlc (b/c we *can* steal it).
We were failing to mark channels as resolved b/c we weren't using later
events to external (but originated from this account) events as signals
to run the channel resolution check.
This fixes that, and adds a test.
Adds schema definitions and manpages for bkpr- commands; also renames
the commands to all start with 'bkpr-', so they're easier to identify/
make runes about.
Anchor outputs are ignored by the clightning wallet, but we keep track
of them in the bookkeeper. This causes problems when we do the balance
checks on restart w/ the balance_snapshot -- it results in us printing
out a journal_entry to 'get rid of' the anchors that the clightning node
doesnt know about.
Instead, we mark some outputs as 'ignored' and exclude these from our
account balance sums when we're comparing to the clightning snapshot.
For income events, break out the amount paid in routing fees vs the
total amount of the *invoice* that is paid.
Also printout these fees, when available, on listaccountevents
This is a rare case where we RBF the output of a penalty until it no
longer has an output value we can reclaim. We ignore the txid for these
events when closing a channel.
We issue events for external deposits (withdrawals) before the tx is
confirmed in a block. To avoid double counting these, we don't count
them as confirmed/included until after they're confirmed. We do this
by keeping the blockheight as zero until the withdraw for the input for
them comes through.
Note that since we don't have any way to note when RBF'd withdraws
aren't eligible for block inclusion anymore, we don't really have a good
heuristic to trim them. Which is fine, they *will* show up in account
events however.
onchain fees are weird at channel close because:
- you may be missing an trimmed htlc (which went to fees)
- the balance from close may have been rounded (msats cant land on
chain)
- the close might have been a past state and you've actually
ended up with more money onchain than you had in the channel. wut
This commit accounts for all of this appropriately, with some tests.
channel_close.debit should equal onchain_fee.credit (for that txid)
plus sum(chain_event.credit [wallet/channel_acct]).
In the penalty case, channel_close.debit becomes channel_close.debit +
penalty_adj.debit, i.e.
channel-close.debit + (penalty_adj.debit) =
onchain_fee.credit
+ sum(chain_event.credit [wallet/channel_acct])
We might only have seen one side of the channel, as shown below. Wait
for both:

The only places which should call try_reconnect now are the "connect"
command, and the disconnect path when it decides there's still an
active channel.
This introduces one subtlety: if we disconnect when there's no active
channel, but then the subd makes one, we have to catch that case!
This temporarily reverts "slow" reconnections to fast ones: see next
patch.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Connectd already does this when we *receive* an error or warning, but
now do it on send. This causes some slight behavior change: we don't
disconnect when we close a channel, for example (our behaviour here
has been inconsistent across versions, depending on the code).
When connectd is told to disconnect, it now does so immediately, and
doesn't wait for subds to drain etc. That simplifies the manual
disconnect case, which now cleans up as it would from any other
disconnection when connectd says it's disconnected.

We want to avoid lost messages in the common cases.
This generalizes our drain code, by giving the subds each 5 seconds to
close themselves, but continue to allow them to send us traffic (if
peer is still connected) and continue to send them traffic.
We continue to send traffic *out* to the peer (if it's still
connected), until all subds are gone. We still have a 5 second timer
to close the connection to peer.
On reconnects, we don't do this "drain period" on reconnects: we kill
immediately.
We fix up one test which was looking for the "disconnect" message
explicitly.

It's caused by a reconnection race: we hold the new incoming connection while we
ask lightningd to kill the old connection. But under some circumstances we leave
the new incoming hanging (with, in this case, old reestablish messages unread!)
and another connection comes in.
Then, later we service the long-gone "incoming" connection, channeld
reads the ancient reestablish message and gets upset.

We cleanup our output tracking for timeout txs when the peer's
htlc_timeout self-expiry is hit; we'd also log its spend if happen to

This is a bit of a race as they can't spend it until the locktime is
available. Hence the flakiness in tests that expected the `htlc_timeout`
to *not* be spent.
Instead, we only log an external's `htlc_timeout` spend in the case
where we also immediately register another output to track for it (only
happens when said htlc is stealable)

Previously we wouldn't notify when a channel moves into state
"CHANNELD_AWAITING_LOCKIN", as this is the original state (so there's
no movement btw states). This meant that it's impossible to track when a
channel's commitment txs have been exchanged and we're waiting for
onchain confirmation.
It's useful to have notice of this initialization though, all in one
place so that the `channel_state_changed` notification can successfully
track the entire lifecycle of a channel, from inception to close.
Note that for v2 "dual-funded" channels, we already notify at the same place, at

Got complaints about us hanging up on some nodes because they don't respond
to pings in a timely manner (e.g. ACINQ?), but that turned out to be something
else.
Nonetheless, we've had reports in the past of LND badly prioritizing gossip
traffic, and thus important messages can get queued behind gossip dumps!

Changelog-Changed: connectd: give busy peers more time to respond to pings.
Because we expire cache every flush, in DEVELOPER mode that can happen in
just over a second. If gossipd takes a while to process the gossip,
this can mean we actually forget we received it from the peer.
Easiest fix is to run this test in non-DEVELOPER mode.
``` # With DEVELOPER, this is long enough for gossip flush.

It actually only sets the prefix for the lightningd core log messages;
the other logs have their own prefix.
Make it a real, process-wide prefix which actually goes in front of the timestamp.

Changelog-Fixed: options: `log-prefix` now correctly prefixes *all* log messages.
Looking at the CI logs, it seems like it took over 5 seconds, so
the unilateral close occurred instead of the expected rejection
of the WIRE_SHUTDOWN reply. Make it bulletproof.

That's useful for "tell me everything about this node" debugging.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Fixes: #5348
Changelog-Added: lightningd: `log-level=debug:<partial-nodeid>` supported to get debug-level logs for everything about a peer.
