02:25 < tomichec> tried to start the lightningd, and got an error regarding `bitcoin-cli estimatesmartfee`. The log  `tail -1000` is http://termbin.com/wbzr Any ideas what is wrong?
02:30 < tomichec> the `bitcoin-cli -testnet estimatesmartfee 2 CONSERVATIVE` that is claimed to be broken returns:

03:00 < artlav> Hello there. 
03:01 -!- rusty [~rusty@pdpc/supporter/bronze/rusty] has joined #c-lightning     
03:01 < artlav> Is there any non-invasive way to get lightningd to dump it's wallet's private keys?
03:03 < artlav> I keep getting it stuck in all sorts of dead end or annoying states, and it won't accept it's own change transactions as addfunds after being reset.
03:04 < artlav> So i had to dump the master key with a printf in populate_secretstuff(void), derive the keys and rescue the coins.

03:34 < HectorJ> Hi all!
03:35 < HectorJ> I'm trying to run c-lightning on mainnet (yes, I understand the risks), but my node is not finding any peers. Am I missing something to kickstart the discovery process? Or does anyone here have a id + ip + port I could try to manually connect to ?
03:35 < HectorJ> Here is what I get from getinfo:
03:35 < HectorJ> { "id" : "0207481a19a3f51a48f134e95afa67cfeffdb38a99b5ad3494a320c4918aaaf579", "port" : 9735, "address" :  	[  		{ "type" : "ipv4", "address" : "163.172.174.151", "port" : 9735 } ], "version" : "v0.5.2-2016-11-21-1566-g145e263", "blockheight" : 504661 }
03:43 < jb55> cdecker: mainnet coming in hot onto 02f6725f9c1c40333b67faea92fd211c183050f28df32cac3f9d69685fe9665432 wish me luck...
03:46 < jb55> oops think I made the channel too small 
03:46 <@cdecker> Oh no, how much is on there?
03:47 < jb55> 380 bits
03:54 < jb55> cdecker: if I open a bigger channel to someone who is connected to you, would it route it through there instead?
03:56 < jb55> or maybe I will just wait for that amount to be enough to buy some stickers lol
03:57 < jb55> oh wait I can buy one sticker with that
03:57 < jb55> nice
03:57 < jb55> well I wouldn't be able to afford closing due to fees?
03:57 < jb55> not sure how that works
04:00 <@cdecker> Yeah, closing is a bitch, I also only managed to buy 1 sticker and forfeited the rest to closing fees

04:11 < shurdeek> hello, does the c-lightining have the equivalent of walletnotify in bitcoind? Like if it can execute a command if an invoice payment comes in.
04:13 < shurdeek> alternatively, am I supposed to call "waitanyinvoice" in a loop? What happens if an invoice payment comes in and there is no waitanyinvoice polling at that time?
04:46 < HectorJ> (for my previous question, found the blockstream node on twitter. So I'm good, gonna try and fund my first mainnet channel)
04:56 -!- moctost [~moctost@cpe-107-9-138-59.neo.res.rr.com] has joined #c-lightning     
05:13 < artlav> What could be causing "failed: WIRE_TEMPORARY_CHANNEL_FAILURE (reply from remote)" on payment send?
05:14 < artlav> Every attempt to pay ends like that.
05:22 <@cdecker> shurdeek, you can either wait for the next invoice completing or wait on a specific invoice
05:23 <@cdecker> artlav, how are you connecting? Could be a multi-hop payment with a channel that has insufficient capacity

05:27 < artlav> I've been going through the list of big nodes on the explolrer site. The last one was 03987a79dfd6089487cc8b3611a94fda8e21a927cd0a0cf381193491b62a7e7190
05:28 < artlav> So i make a channel to it, getroute, sendpay, error.
05:28 < artlav> Now i'm trying 02c39955c1579afe4824dc0ef4493fdf7f3660b158cf6d367d8570b9f19683afb5, so far the confirmations are pending.
05:29 < artlav> And yes, it was routing via a third node.

07:35 < artlav> ow, is testnet slow today...
07:35 < artlav> Anyway, the other node gives me "failed: WIRE_FINAL_INCORRECT_CLTV_EXPIRY (reply from remote)"
07:53 <@cdecker> The cltv expiry error usually means that there was a block inbetween. What's the other endpoint you're trying to send to?

08:11 < artlav> cdecker: Any endpoint. Tried Yalls and lightninggem.
08:11 < artlav> What do you mean by "there was a block inbetween"?
08:16 < shurdeek> cdecker: so basically the rpc call waitanyinvoice is a "replacement" for walletnotify? Basically I need to process payments in the backend, now I use bitcoind with walletnotify.

18:37 < artlav> Another node, another "failed: WIRE_TEMPORARY_CHANNEL_FAILURE (reply from remote)"
18:37 < artlav> I'm yet to get one payment to succeed...
18:38 < artlav> rusty: I was thinking more in terms of having a recovery seed at wallet creation. Or is that bad too? It seem to use the same HSM seed to generate the keys for the channels.
18:41 < rusty> artlav: well, there's a single BIP32 seed, and that should cover every normal tx.  But that doesn't cover the complex scripts used for much of the channel, which really need special handling.  So you really need onchaind to spend those to that BIP32 wallet...
18:43 < rusty> artlav: wow...  our diagnostics are pretty bad, plus #550 means we don't feed those errors back to retry.
18:44 < rusty> artlav: are you sending more than your channel capacity (minus 1%)?

19:49 < artlav> rusty: Another complication is that if i shut down lightningd while a channel is open and then restart it, all sorts of weird things happen.
19:50 < rusty> artlav: ?  It should reconnect, reestablish and be happy.  What happens?
19:50 < artlav> Ranging from it being unable to find itself in routing, to connect hanging, to a crash in db_exec_prepared_ or so.
19:51 < artlav> And yes, there was enough funds in the channels i tried.
19:56 < artlav> Pulled the latest one from git, now rebuilding. Will see if the crash is still reproducible.

20:01 < rusty> artlav: Zmn is working on #550 now.  What happens is we get an error back.. then ignore it!  We should be disabling the channel when this happens, so we can re-route.
