After some discussion with @shesek, and my own usage, we agreed that
a more comprehensive interface, which explicitly supports grouping,
is desirable.
Thus keys are now arrays, with the semantic that a key is either a
parent or has a value, never both.
For convenience in the JSON schema, we always return them as arrays,
though we accept simple strings as arguments.

We add a generation counter, and allow update or del conditional

Formalizes error codes, too, since we have more now.

This means remembering the connection direction. We also use the address to try
to reconnect, which we shouldn't bother with if they connect to us.
For peers from the database, we currently always save the addr: we shouldn't really
do this if they connected to us, since it's not useful for reconnecting (we don't
show the addr in JSON reply to listpeers unless we're connected, so it's only an
internal issue). This is left for future work.

The leak exists if we `tal_free` the result array onto another parent,
but the `ctx` we allocated on is still valid. This leads to a
temporary gap in the ownership tree which is then reported as the

We need to know if they've sent us their sigs message yet. Ideally, we'd
be able to check the 'finalness' of the PSBT, however if the peer
doesn't have any inputs to the channel this doesn't work.
This reverts commit c239a7161b.
The goal of c239a716 was to reduce the memory footprint of our
internal UTXO set tracking, and testing against the sqlite3 backend
showed no performance impact. We have since found that the added
roundtrips to the DB server with postgres was having a considerable
performance impact, and backups would also bloat due to the increased
number of queries.
Undoing this change skips the noop updates that were causing this
regression.
Changelog-Fixed: db: Fixed a performance regression during block sync, resulting in many more queries against the DB than necessary.

We defer the notification to gossipd till the end of the spends. By itself not
a huge change, but it allows us to later migrate to doing updates blindly and
using the DB as our ground truth. It also allows us to simplify the
`wallet_outpoint_spend` semantics to not return two values in the next commit.
This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.
This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined. Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: JSON-RPC: `withdraw` now randomizes input and output order, not BIP69.
Marking spent means if the transaction doesn't confirm for some
reason, the user will need to force a rescan to find the funds. Now
we have timed reservations, reserving for (an additional) 12 hours
should be sufficient.
We also take this opportunity (now we have our own callback path)
to record the tx in the wallet only on success.

we're about to add a migration that requires access to the bip32_key

run.
here we patch it through so that every migration can access it
This is a new fundamental routine to obtain UTXOs from the database.

We were assuming `wallet_channel_insert` that there cannot be a matching peer
if our in-memory representation isn't bound to it (`dbid == 0`). If we then
attempt to create the peer, and we already had one it'd cause a unique
constraint violation. As far as I can tell this could end up happening if we
have an uncommitted channel, and then exited without cleanup (`tal_destructor`
on the uncommitted channel not running). This could then leave the peer in the
DB. This is because the constraint that every peer has at least one channel is
not enforce at DB level, but rather in destructors that may or may not run.
Changelog-Fixed: Fixed a failing assertion if we reconnect to a peer that we had a channel with before, and then attempt to insert the peer into the DB twice.
Reserve and unreserve wallet UTXOs using a PSBT which includes those
inputs.
Note that currently we unreserve inputs everytime the node restarts.
This will be addressed in a future commit.
Changelog-Added: JSON-RPC: Adds two new rpc methods, `reserveinputs` and `unreserveinputs`, which allow for reserving or unreserving wallet UTXOs
when re-populating a channel's data from the database, since we don't
store the psbt data (with input scripts + amounts), we need to
re-populate it.
the right solution is to patch the psbt into the database; for now we
'monkey-patch' it in.
This moves the notification for our coin spends from when it's
successfully submited to the mempool to when they're confirmed in a
block.
We also add an 'informational' notice tagged as `spend_track` which
can be used to track which transaction a wallet output was spent in.
Previously we were annotating every movement with the blockheight of
lightningd at notification time. Which is lossy in terms of info, and
won't be helpful for reorg reconciliation. Here we switch over to
logging chain moves iff they've been confirmed.
Next PR will fix this up for withdrawals, which are currently tagged
with a blockheight of zero, since we log on successful send.
The current plan for coin movements involves tagging
origination/destination htlc's with a separate tag from 'routed' htlcs
(which pass through our node). In order to do this, we need a persistent flag on
incoming htlcs as to whether or not we are the final destination.
