06:48 < sword_smith> If anyone wants a few main net sats, send me an invoice from an MPP wallet.
06:56 < sword_smith> I was on 0.8.2.1 previously, now on 0.9.0. Is MPP activated automatically and by default? And should I just keep using the same RPC functions as I have used so far?
06:57 < darosior> Yes it is, just use pay
06:57 <@cdecker> Yes, it's active by default and everything should work normally. The one exception is `listsendpays` which you probably want to use `listpays` instead (the former lists partia; payments, the latter aggregates them into the logical payment)
06:58 -!- liberliver [~Thunderbi@144.49.211.130.bc.googleusercontent.com] has joined #c-lightning
07:26 < sword_smith> In my setup I call `getroute` prior to making the payment and I only attempt the payment if `getroute` succeeds. Does `getroute` take MPP into account?

07:36 <@cdecker> Well MPP itself relies on getroute to compute routes, so if it can't find a working route MPP will also not succeed.
07:37 <@cdecker> That is unless there are routehints, which result in special getroute calls in `pay` (using the routehint entrypoint as destination rather than the non-public recipient)
07:37 <@cdecker> So MPP may find a route when a simple `getroute` call fails.

08:05 < vincenzopalazzo> When the I split a payment with in two different route, the payment store in the database are 2 different payment with partid different but with the same payment_hash, right? I understand? if yes, in this cases when I make the query on DB by hash I can receive the list of payments?
08:06 < vincenzopalazzo> Ops, sorry! I miss to say -> "Hello guys I need to make a double check of my code comprehension".

12:03 < sword_smith> cdecker: Thanks for the explanation. I wonder if my call to getroute should be removed then.
12:04 < sword_smith> I am just trying to avoid the situation where I don't know if the payment will go through or not.
12:05 < sword_smith> Where the call to `pay` is hanging.

13:14 <@cdecker> sword_smith: in that case the `getroute` call is redundant. `pay` internally does a bit more than calling `getroute` (routehints), but it will also exit almost immediately if it can't find a route (it will never hang if there isn't a way to send at least one partial payment)
13:14 <@cdecker> It might try to split a couple of times, notice that it can't find a route and then exit
13:15 <@cdecker> vincenzopalazzo: yes, `listpayments` will return basically a 1-to-1 DB query with all the individual partial payments, whereas `listpays` aggregates all the parts and returns one consolidated payment for each `payment_hash`
13:16 <@cdecker> Reaching directly into the DB might not be good (for sqlite3) since queries can lock the DB file and then `lightningd` might abort since it can't write to the DB
13:17 <@cdecker> (the testing framework will first copy the DB file before querying on the copy, in case you were wondering)

14:19 < MrHash> hello. i've got a slightly strange case here where i'm doing a test payment on regtest to a 100sat invoice with a maxfeepercent of 1, but the msatoshi_sent result is 101001msat whic is 1msat over the maxfeepercent
14:20 < MrHash> base fee is 1000msat
14:20 < MrHash> on routing node in the middle
14:21 < MrHash> fee_per_mil = 10
14:21 < MrHash> so is the maxfeepercent a fuzzy limit?

17:49 < zmnscpxj_> darosior: sorry, not sure why timestamps are weird
17:50 < zmnscpxj_> darosior: for retry-exhaustion, maybe print an plugin_log(plugin, LOG_BROKEN), then wait one second before actually plugin_err?

17:52 < zmnscpxj_> MrHash: have not noticed any issue yet, hmmm
17:55 < MrHash> zmnscpxj_: i did a simple pay from A-C via B where the invoice amount was 200 sat and the maxfeepercent was 0.1 (max 200msat), that should fail the pay because the routing base fee is 1000msat but the payment is succesful
17:55 < zmnscpxj_> it fails if you use legacypay instead?
17:56 -!- rusty [~rusty@pdpc/supporter/bronze/rusty] has joined #c-lightning
17:57 < MrHash> no passes with legacypay also
17:57 < zmnscpxj_> ...crap
17:57 < MrHash> please try anyway, maybe i'm doing something wrong
17:58 < MrHash> exemptfee means fee amount which is exempt or invoice amount that ignores maxfeepercent?
17:59 < MrHash> docs say 5sats is exempt from maxfeepercent limit
17:59 -!- cryptosoap [~cryptosoa@gateway/tor-sasl/cryptosoap] has joined #c-lightning
17:59 < zmnscpxj_> ah right
17:59 < zmnscpxj_> exempt*fee*
17:59 < zmnscpxj_> always thought it was a limit on the payment size, haha
18:00 < zmnscpxj_> yes that is correct
18:00 < zmnscpxj_> exemptfee makes an exemption for *fees* lower than 5 sats / 5000msat
18:00 < MrHash> ah ok so because the fee is less than 5sats, therefor it passes
18:01 < zmnscpxj_> yes
18:01 < MrHash> understood, thanks
18:01 < rusty> niftynei: can I have review on 3868 please?  It expands testing for Travis,. so it should catch if we merge something wrong; I
