Interesting finding:

xud@xud-test-1:~$ xucli sell 0.1 LTC/BTC 0.00775 --stream
swapped 0.1 LTC with peer order 7e8fa1c0-7f34-11e9-9128-9deb3935a9ad
xud@xud-test-1:~$

looks like that if the first leg is LTC, it works well.

I'm stumped as to why the taker's xud crashed. Is this reproducible for you? It would also be very helpful to have the panic stack trace when it crashed if you can access it, that won't be in the actual log files though.

ghost · 2019-05-28T18:30:02Z

Managed to reproduce the issue. Just like Offer said - direct channels, sanity checks pass, real swap fails. What is interesting is that I used the same xud nodes for non-direct channel swap and it succeeded without problems.

@kilrau Adding P1 back again. I see this from time to time. Not sure you want to see it when you demo in Munich

kilrau · 2019-05-29T09:27:13Z

Certainly not. @sangaman

ghost · 2019-05-29T10:01:58Z

This issue can be divided into 2 parts:

xud crashing when trying to send SwapFailedPacket - fixed in fix(swaps): prevent SwapFailurePacket crash #997
direct channel LTC/BTC swap failing with UnknownPaymentHash message from lnd
As mentioned by Offer above - a temporary workaround for this is to have maker initiate a sell order first.

kilrau · 2019-05-29T11:29:40Z

Since 1. is fixed in #997, this issue is about fixing 2.

offerm · 2019-05-31T11:30:33Z

I have the same problem with sell orders of WETH/BTC.

The second leg is BTC and it fails with UnknownNextPeer.

This can be LND issue so we should try to reproduce with LND's command line (using send to route)

offerm · 2019-05-31T11:42:47Z

I have noticed some related issues on LND.
Upgrade to 0.61-beta did not solved it.

kilrau · 2019-06-04T15:15:58Z

We discussed on the call to just use sendpayment and get rid of sendtoroute. It allows to set cltv delta now. @erkarl

offerm · 2019-06-04T15:57:18Z

Let's discuss it before implementation.

Sure, please jump in with implementation details to review @erkarl

offerm · 2019-06-05T15:24:11Z

First, we have a problem that we don’t understand and not sure how to reproduce. Changing the payment api that we use due to this problem is just a guess. Probably not a good one.

I would not change this before we are live and before we have a good reason for it.

And, we should understand how we use cltv without the route.

Have a feeling that the reason for the problem has to do with the open htlcs that we have when we used sanity swaps. Maybe the number of open Htlc got to high?

ghost · 2019-06-06T08:59:44Z

@offerm I'm able to reproduce the problem on my machines 100% of the time.

I did a quick proof of concept with sendPayment to make sure that the issue is related to sendToRoute. Turns out it doesn't solve the problem. Going to dig deeper...

ghost · 2019-06-07T14:38:05Z

@offerm

Upon further inspection I discovered 2 problems.

lndrpc.SendToRouteSync is broken when we pass in a route that has only 1 hop. It will error with UnknownNextPeer message. I also tried on current lnd master v0.6.1-beta-228-gaa5156a1a985ef3e0b1e6ad48a081125a465870d where SendToRouteRequest.routes is deprecated in favor of SendToRouteRequest.route - same result. What is interesting is that I can only replicate the problem on testnet, but not on my local simnet.

The second problem I noticed on xud level was that we're not waiting for the hold invoice state to become OPEN and in case of low latency the taker can attempt to pay us "too fast" when accepting the deal, causing the payment to occasionally error with UnknownPaymentHash. This is the reason I mentioned yesterday that switching to lndrpc.SendPayment didn't work.

I suggest we move away from lndrpc.SendToRouteSync to using lndrpc.SendPayment and create an issue to lnd. We're already using it for sanity swaps. To address Offer's concern above - it also allows to specify the final_cltv_delta.

kilrau · 2019-06-07T15:08:08Z

SGTM, please go ahead.

Not sure if v0.6.1-beta-228-gaa5156a1a985ef3e0b1e6ad48a081125a465870d includes the new error output of lightningnetwork/lnd#3113, but what exactly did it throw?

offerm · 2019-06-07T15:11:19Z

Nice finding with the UnknownPaymentHash !!! About SendToRouteSync replcing SendPayment: - Can we find first what is the reason for the problem and why we don't see it [any more] on simnet? - Also before we switch - how are we going to decide which value to provide as final_cltv_delta?

Can we find first what is the reason for the problem and why we don't see it [any more] on simnet?

That is a very good question that bothers me.

Also before we switch - how are we going to decide which value to provide as final_cltv_delta?

If we're the the taker we'll use deal.makerCltvDelta that the maker has set. In case of maker we'll use deal.takerCltvDelta set by the taker.

@offerm

Please also note that I had to use the following patch on xud level in order to produce the UnknownNextPeer error. This is due to fact that I upgraded to latest master lnd gaa5156a1a985ef3e0b1e6ad48a081125a465870d and cannot downgrade because of database migrations. The latest master doesn't support setRoutes so I had to specify a single route via setRoute.
