# Excludes channel, then ignores routehint which includes that, then
# it excludes other channel.

E +2
```
The invoice we use at the end has a routehint: 50% of the time it's
to l2 (which fails), 50% to l5 (which succeeds).
Change it to create invoice before channel with l5 so it does the
retry like we expect here.

We sum up the amounts just like we do with `amount_sent`, however we may have
parts that don't have that annotation, so make it optional.
Suggested-by: Rusty Russell <@rustyrussell>
Since we started using `sendonion` in the `pay` plugin we no longer
automatically have the `amount` annotation on (partial) payments. This
replicates the issue so we can fix it.

The adaptive MPP test was showing an issue with always using a routehint, even
when it wasn't necessary: we would insist on routhing to the entrypoint of the
routehint, even through the actual destination. If a channel on that loop
would result being over capacity we'd slam below 0, and then increase again by
unapplying the route. The solution really is not to insist on routing through
a routehint, so we implement random skipping of routehints, and we rotate them
if we have multiples.
Changelog-Fixed: plugin: `bcli` no longer logs a harmless warning about being unable to connect to the JSON-RPC interface.
Changelog-Added: plugin: Plugins can opt out of having an RPC connection automatically initialized on startup.
This PR includes the fix discussed on PR #3855. This fix was tested with the use case described inside the issue and worked.
Fixes: #3855
Changelog-None
The test had part 1 and 2 backward, but still worked. When I copied that to
*after* the test had succeeded, it complained. It should always complain,
to catch bugs.

This wasn't important before, but now we have MPP it's good to enforce.

While we were unsetting the `payment->cmd` in case of a success to signal that
we should not return to the JSON-RPC command twice, we were not doing that in
the case of failures. This was causing multiple responses to a single incoming
command, and `lightningd` was correctly killing the plugin. This issue was
introduced through early returns (anything setting `payment->abort=true`) and
was caused in Rusty's case through an MPP timeout.

fundpsbt forces the caller to manually add their weight * feerate
to the satoshis they ask for. That means no named feerates.
Instead, create a startweight parameter and do the calc for them
internally, and return the feerate we used (and, while we're at it,
the estimated final weight).
This API change is best done now, as it would otherwise have to
be appended as a parameter.

This exercises something that is simply not possible without MPP, i.e., the
bundling of multiple paths to get sufficient capacity to perform the payment.
Changelog-Added: The MPP presplit modifier splits large payments into 10k satoshi parts to maximize chances of performing the payment and to obfuscate the overall amount being sent.
We're actually going to deprecate this, so don't add new features!

Changelog-Added: ***REMOVE*** JSON-API: `txprepare` returns a psbt version of the created transaction
It uses reservations heavily, and assumed we generated change, etc.
It's now a simpler test, in many ways.

reserveinputs marks UTXOs reserved for 12 hours, so we won't select them
for spending: unreserveinputs marks them available again.
Exposes param_psbt() for wider use.
Disabled the test_sign_and_send_psbt since we're altering the API;
the final patch restores it.

Technically an API break, but nobody relies on these I hope!
Note that the feerates warning was buried inside the style object:
it should be top-level.

As suggested during the paymod-03 review it is better to activate the new code
right away, and give users an escape hatch to use the legacy code instead. The
way I implemented it allows using either `legacypay` or `pay` and then set
`legacy` to switch to the other implementation.
Changelog-Added: JSON-RPC: The `pay` command now uses the new payment flow, the new `legacypay` command can be used to issue payment with the legacy code if required.

This makes use of the payment modifier structure to just add the preimage to
the TLV payload for the last hop.
Changelog-Added: JSON-RPC: The `keysend` command allows sending to a node without requiring an invoice first.
This commit collects the changes required to the tests caused by the changes
to the `pay` and `paystatus` commands. They are also rather good hints as to
what these changes entail.
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.
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'}"

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.

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.

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.
