We want to differentiate a wrong block-height from other failure reasons, such
as an unknown `payment_hash`, so we skip the `waitblockheight` if we're
already at the correct height.
Add/remove the HTLC amount from the channel hints so concurrent getroute calls
have the correct exclusions. This can sometimes underflow, if we're unlucky
and call getroute too closely, but that's not a big issue, it can only result
in a failed MPP attempt too many, nothing fatal, and it'll get corrected based
on the result returned by the failing node.
Since we change the interface for `pay` and `paystatus` we need a way to
determine which one to expect. This just parses the COMPAT_Vxyz flags and
allows us to check if, based on the configuration, we are in compat mode for
that set of changes or not.
These are primarily the fee and cltv constraints that we need to keep up to
date in order to give modifiers a correct view of what is and what isn't
allowed.
Changelog-Fixed: Actually make the password argument optional for `guesstoremote` and `dumpcommitments` sub-commands, as shown in our documentation and help text.
Reported by `Barno` on #c-lightning IRC.
Before this, docker image will never detects that
`lightning-rpc` was created if it is running in regtest
or testnet, because the file will be created under
subfolder for each network name, and entrypoint does not
check "lightning-rpc" file in those folders.
By specifying `LIGHTNINGD_NETWORK` environment var
in dockerfile, we can now check correct path.
Changelog-Added: Docker build now includes `LIGHTNINGD_NETWORK` ENV variable which defaults to "bitcoin". An user can override this (e.g. by `-e` option in `docker run`) to run docker container in regtest or testnet or any valid argument to `--network`.
Make sure we've actually confirmed the HTLC; if it's not confirmed yet
then we won't fast-fail it, and we'll timeout instead:
```
> l1.rpc.waitsendpay(payment_hash=inv['payment_hash'], timeout=TIMEOUT, partid=1)
E AssertionError: Pattern 'WIRE_PERMANENT_CHANNEL_FAILURE \\(reply from remote\\)' not found in "RPC call failed: method: waitsendpay, payload: {'payment_hash': 'c186643391469aa8190415496c85b1eb789cb2b756a76d4c9ce21dd34c698d92', 'timeout': 30, 'partid': 1}, error: {'code': 200, 'message': 'Timed out while waiting'}"

This is the only place outside the wallet code where we create
a 'struct utxo', so it makes sense for us to move that logic inside
the wallet.

It looked like we weren't printing the address on closing outputs.
But we are, because the 'scriptPubkey' field is in the 'outputs' db
table since 0.7.3 (66a47d2761).
So make the logic clearer, and remove a completely bogus comment (UTXOs
with closing_info are definitely spendable!).
We export the json_add_utxos() for future use, too.

We're not allowed to command_fail() once we've started json_success.
That's OK, because encoding a known output can only fail if something is
badly, badly wrong.

These are pulled from wallet/wallet.c, with the fix now that we grind sigs.
This reduces the fees we pay slightly, as you can see in the coinmoves changes.
I now print out all the coin moves in suitable format before we match:
you only see this if the test fails, but it's really helpful.

Most user-contributed plugins are written in python, and not having it
available in the docker image is rather annoying to work around. So we just
add that tiny dependency to the image.
Fixes#3765
Fixes: #3815
Changelog-Fixed: Fixed a deviation from BOLT#2: if both nodes advertised `option_upfront_shutdown_script` feature: MUST include ... a zero-length `shutdown_scriptpubkey`.
By setting nLocktime to the current block, the reorg test
"test_funding_reorg_remote_lags" actually drops the funding transaction
entirely when a reorg happens.
Except the 1 in 10 cases where nLocktime is randomly set to 1-10
blocks earlier.
This implies, strongly, that we hit "restart" too often on Travis.

We could end up with multiple channel hints, which is a bit wasteful. We now
look for existing ones before adding a new one, and if one exists we use the
more restrictive parameters.
Suggested-by: Lisa Neigut <@niftynei>
We're lucky that we can distinguish the severity of the failure based on the
failcode, so we bubble up the one with the maximum failcode, and let callers
inspect details if they need more information.
There is a race between `getroute` learning that our peer accepts TLVs and us
initiating the payment. Waiting for announcements ensures we always use TLVs,
matching our expectation in the test / plugin.
We can have quite detailed information about our local channels, so call
`listpeers` before the `getroute` call on the root payment, to seed that
information in the channel_hints.
