We used to only set it for single-use offers (where it's required),
but it's still interesting for multi-use offers, so let's keep it
there.
We also put this field in the documentation.

Since we turned many errors into warnings, we want our tests to fail
when they happen unexpectedly. We make WARNING clear in the strings
we print, too, to help out.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
And make all the callers choose which one. In general, I prefer warn,
which lets them reconnect and try again, however some places are either
stated that they must be errors in the spec itself, or in openingd
where we abandon the channel when we close the connection anyway.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: Protocol: we now send warning messages and close the connection, except on unrecoverable errors.
We construct the route manually so we may not have the
channel_announcement yet. But we can get an update from the error
packet, which can lead to:

We fix up the test by using pay, instead of sendpay (and making pay log
the expected message).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: sendpay no longer extracts updates from errors, the caller should do it from the `raw_message`.
The fetchinvoice and offers plugins disable themselves if the option
isn't enabled (it's enabled by default on EXPERIMENTAL_FEATURES).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: `experimental-offers` enables fetch, payment and creation of (early draft) offers.
As per lastest revision of the spec, we can specify amounts in invoice
requests even if the offer already specifies it, as long as we exceed
the amount given. This allows for tipping, and amount obfuscation.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Means a reshuffle of our logic: we want to multiply by quantity before
conversion for maximum accuracy.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This avoids a footgun where they create an offer then we can't create
the invoice because they don't have a converter plugin.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We split `send_invoice` offers inoo offerout (for want of a better name).
This simplifies the API.
Also took the opportunity to move the `vendor` tag to immediately
follow `description` (our tests use arguments by keywords, so no
change there).

refund offers are implied send_invoice offers. And send_invoice offers
are implied single-use offers, though it can also make sense to have
a non-send_invoice offer be single-use.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
1. Hoist 7200 constant into the bolt12 heade2.
2. Make preimage the last createinvoice arg, so we could make it optional.
3. Check the validity of the preimage in createinvoice.
4. Always output used flag in listoffers.
5. Rename wallet offer iterators to offer_id iterators.
6. Fix paramter typos.
7. Rename `local_offer_id` parameter to `localofferid`.
8. Add reference constraints on local_offer_id db fields.
9. Remove cut/paste comment.
10. Clarify source of fatal() messages in wallet.

We were blindly initiating the keysend payment, which could lead to
confusing outcomes. This adds a very specific error message to the
error returned.
Changelog-Fixed: keysend: Keysend now checks whether the destination supports keysend before attempting a payment. If not a more informative error is returned.
This will allow nodes (with log-level=debug) to gather how many payments
are made without payment_secrets. We need to know this so we know when
we can make them compulsory.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
In both cases the flakyness arises from the destination not knowing about the
modified fees of the forwarding node, thus including the outdated details in
the routehint, and the sender being unlucky and always trying with the
routehint anyway.
The long-term solutions to this is going to be #4111, this commit just reduces
the flakyness to get back to business.
Changelog-Added: JSON-RPC: delpay a new method to delete the payment completed or failed.
Signed-off-by: Vincenzo Palazzo <vincenzopalazzodev@gmail.com>
Fixes: #3926
(probably)
Changelog-Fixed: pay: Also limit the number of splits if the payee seems to have a low number of channels that can enter it, given the max-concurrent-htlcs limit.
I screwed up the rotation logic in an earlier varient of this PR, and
it lead me to discover why test_mpp_interference_2 was flaky.
Really, we should keep a fuzzy estimator of how much payment is
outstanding, but in practice rotation is probably good enough.
