If we fund a channel between two nodes, then mine all the blocks to
announce it, any other nodes may see the announcement before the

The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.
Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.
Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.

Changelog-Fixed: plugin: `dev-sendcustommsg` included the type and length prefix when sending a message.
We were always prefixing the `message` field with the internal type

the type being constant is of no interest to the plugin and the length
being implicit due to the JSON-encoding.

make it clear.
Secondly, we assume that the wallet considers outputs spent as soon as
we created the tx: this will not be true once withdraw uses sendpsbt.
So, we generate blocks, but now sometimes withdraw will pick up change
txs, so we need to reserve them to avoid that messing our coinmovements.

This adapts our fee estimations requests to the Bitcoin backend to the
new semantic, and batch the requests.
This makes our request for fees much simpler, and leaves some more

Changelog-Changed: We now batch the requests for fee estimation to our Bitcoin backend.
Changelog-Changed: We now get more fine-grained fee estimation from our Bitcoin backend.
We kept track of an URGENT, a NORMAL, and a SLOW feerate. They were used
for opening (NORMAL), mutual (NORMAL), UNILATERAL (URGENT) transactions
as well as minimum and maximum estimations, and onchain resolution.
We now keep track of more fine-grained feerates:
- `opening` used for funding and also misc transactions
- `mutual_close` used for the mutual close transaction
- `unilateral_close` used for unilateral close (commitment transactions)
- `delayed_to_us` used for resolving our output from our unilateral close
- `htlc_resolution` used for resolving onchain HTLCs
- `penalty` used for resolving revoked transactions
We don't modify our requests to our Bitcoin backend, as the next commit
will batch them !

This completes the custommsg epic, finally we are back where we began all that
time ago (about 4 hours really...): in a plugin that implements some custom
logic.
This solves a couple of issues with the need to synchronously drop the
connection in case we were required to understand what the peer was talking
about while still allowing users to experiment, just not kill connections.
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.
Changelog-Add: Implement `waitblockheight` to wait for a specific blockheight.
Some Linux OSs impose a length limit on the path a Unix socket may have. This
is not an issue in `lightningd` since we `chdir()` into that directory before
opening the socket, however in pyln this became a problem for some tests,
since we use absolute paths in the testing framework. It's also a rather
strange quirk to expose to users.
This patch introduces a `UnixSocket` abstraction that attempts to work around
these limitations by aliasing the directory containing the socket into
`/proc/self/fd` and then connecting using that alias.

I had a report of a 0.7.2 user whose node hadn't appeared on 1ml. Their
node_announcement wasn't visible to my node, either.
I suspect this is a consequence of recent version reducing the amount of
gossip they send, as well as large nodes increasingly turning off gossip
altogether from some peers (as we do). We should ignore timestamp filters
for our own channels: the easiest way to do this is to push them out
directly from gossipd (other messages are sent via the store).
We change channeld to wrap the local channel_announcements: previously
we just handed it to gossipd as for any other gossip message we received
from our peer. Now gossipd knows to push it out, as it's local.
This interferes with the logic in tests/test_misc.py::test_htlc_send_timeout
which expects the node_announcement message last, so we generalize
that too.

In this one, we always send my_current_per_commitment_point, though it's
ignored. And we have our official feature numbers.

This is an issue that was raised in #2665: some of the dependencies where
causing warnings to be added to the logs about deprecated dependencies. Since
I did not get these warnings I just blanket updated all the dependencies in
the hopes of getting the warnings to resolve.

This is probably worth preventing.
1. Our depth estimate would be inaccurate possibly leading to us
timing out too early.
2. If we're not up-to-date our onchain funds are unknown.
3. We wouldn't be able to send or receive HTLCs until we're synced anyway.

We want to still allow incoming connections, and reestablishment of
channels, but if one tries to give us an HTLC, stall until we're
synced.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
If we don't know block height, we shouldn't be sending HTLCs. This
stops us forwarding HTLCs as well as new payments.

@renepickhardt has a shell script we broke. While we still produce
perfectly valid JSON, we should not gratuitously change tool output.
Plus, I prefer the missing space before the ':'.

Dumb programs which have a --daemon option call fork() early. This is
terrible UX since startup errors get lost: the program exits with
"success" immediately then you discover via the logs that it didn't
start at all.
However, forking late introduced a heap of problems with changing
pids. Instead, fork early but keep stderr and the parent around: if
we fail early on, the parent fails with us. We release our parent
with an explicit action just before the main loop.

We create our children then fork, so we're not a parent. I noticed this
because 'lightning-cli stop' takes a long time: this is because it tries to
wait for them and they don't respond.

Our previous param support was a bit limited in this case.
We create a dev- command multiplexer, so we can exercise it.

And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).

- mock_rpc function now returns full JSON-RPC response, is much cleaner
- Since reached_announce_depth counting is fixed when starting
channeld, we don't need the 7th block to tell depth anymore.
It would always return bech32; fix that, and don't bother printing
it if they use the (new) 'all' parameter.
This API was introduced in 3e67c09d5e,
which means it wasn't in a release so no CHANGELOG entry necessary.

Reorg changes short_channel_id after lockin of private channel, while
one node restarts.
test that:
- peer->depth_togo in billboard decrements
- reorg and scid change is detected by running node and restarting node
- both `old` and `new` scids are in rtable
Also added a comment to test_blockchaintrack to clarify.
Because the call (wallet_extract_owned outputs) that prints that line can happen
_before_ or _after_ confirmation in block, adding `CONFIRMED` in the later.
This brings up an interesting quirk though, in that we report "3
attempts", where we really should have done one.

Fixes#2518
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Changelog-fixed: `minconf` no longer gets wrapped around for large values, which was causing funds with insufficient confirmations to be selected.
The user can explicitly create such things (within [] or ") as we paste
those cases literally, but not for the simple cases.
Fixes: #2550

They don't clean up after themselves, so best we do it here (by this
point we've already done the pid check to make sure we're the only
lightningd here anyway).

In particular, the assert when `--addr=/sockname` is used, and that it
doesn't clean up on restart, requiring manual deletion of the socket.
