932016-10-03T06:30:30 *** luke-jr has joined #bitcoin-core-dev
942016-10-03T06:32:48 <wumpus> that wouldn't be a bad idea, actually
952016-10-03T06:33:34 <wumpus> that same path would trigger for people building without HAVE_CONFIG_H, e.g. people trying to build with custom-rolled build systems, such as adding everyting into a MSVC project
962016-10-03T06:33:59 <wumpus> currently one'd get a whole slew of unrealistic defaults (although the windows one would work out)
972016-10-03T06:34:15 <wumpus> would fork out for HAVE_DAEMON I mean. Not for other config.h options
982016-10-03T06:35:53 <gmaxwell> libsecp256k1 does this.

1082016-10-03T06:51:44 <wumpus> jonasschnelli: looks like your testnet DNS seed is failing again
1092016-10-03T06:52:55 <wumpus> if it keeps running and reporting to logs but not serving requests it seems a deeper issue

1112016-10-03T07:02:53 <gmaxwell> thats not good.
1122016-10-03T07:03:22 <wumpus> time for the ban hammer?
1132016-10-03T07:03:57 <gmaxwell> yea, looks like that amazon spy thing is back.. on new IPs.
1142016-10-03T07:04:15 <luke-jr> they seem to have given up on me still

1172016-10-03T07:06:08 <gmaxwell> hm. rm my debuglog and kill -HUP appears to have not freed the disk space. (on 0.13.x back a few weeks)

1202016-10-03T07:07:00 <wumpus> if not the debug log, what is using your disk space?
1212016-10-03T07:07:34 <gmaxwell> I mean, I had a 20gb debug.log, and 2gb free. Deleted the log. kill -HUP the daemon.. still 2gb free.
1222016-10-03T07:07:35 <wumpus> oh or is it still holding a reference to the deleted file
1232016-10-03T07:07:38 <gmaxwell> that.
1242016-10-03T07:08:06 <wumpus> there's probably some lsof trick to get rid of that
1252016-10-03T07:09:01 <wumpus> it indicates that there is some fd leak
1262016-10-03T07:09:10 <gmaxwell> yea, actually I can probably figure out which thread it is.
1272016-10-03T07:09:47 <wumpus> yes and then you can find the fd in /proc and trunacte it

1632016-10-03T09:09:27 <btcdrak> wumpus: he is on Telegram reliably.
1642016-10-03T09:10:08 <wumpus> I really dislike using my phone to chat. But I'll consider it
1652016-10-03T09:11:34 <wumpus> if only all those zillions of new phone chat programs had an IRC interface, or, even a publically documented API
1662016-10-03T09:13:11 <btcdrak> wumpus: you can use https://web.telegram.org
1672016-10-03T09:13:23 <wumpus> its the same silly mess as in the 90's with icq, msn, aol etc all over again, until programs like pidgin came along
1682016-10-03T09:13:42 <btcdrak> fully agree. it's annoying.
1692016-10-03T09:14:13 <kinlo> wumpus: bitlbee with libpurple can act as a gateway between telegram and irc. I have my telegram contacts just in my ircclient like all others

1712016-10-03T09:29:57 <wumpus> kinlo: there's a libpurple backend for telegram? that's awesome. Hadn't expected so, for some reason, usually those things try very hard to be closed down to third-party applications.
1722016-10-03T09:30:43 <wumpus> btcdrak: nice, web is preferable to phone at least :)
1732016-10-03T09:31:18 <sipa> all my contacts are hangouts or irc, both work fine in bitlbee
1742016-10-03T09:31:32 <kinlo> wumpus: telegram is afaik an "open standard", not a good one, but they are not closed minded like whatsapp
1752016-10-03T09:31:33 <sipa> eh, irc doesn't even need bitlbee
1762016-10-03T09:32:03 <wumpus> you're lucky. Some of mine insist on whatsapp, others on signal, others on telegram, others on skype, others on ricochet, ...
1772016-10-03T09:32:23 <sipa> never heard about ricochet
1782016-10-03T09:32:41 <kinlo> whatsapp is a bitch, dont assume you'll be able to handle that w/o official client, but telegram, skype, ricochet all have bitlbee options afaik
1792016-10-03T09:32:49 <sipa> oh, i have signal too, but only with people i can reach in other ways
1802016-10-03T09:33:39 <wumpus> ricochet is chat over tor hidden services, it's an open source protocol, however I don't think e.g. libpurple integrates it

2152016-10-03T12:05:50 <wumpus> cfields_: did you know that ssh is set up to pass through LC_* environment variables by default on debian and derivatives? I never knew, just found out with a weird issue. I guess gitian already takes this into account.
2162016-10-03T12:13:09 <achow101> what are these nodes with 52.x IPs?
2172016-10-03T12:14:02 <wumpus> achow101: no one knows, guesses range from spy nodes to a (slow) DoS

2202016-10-03T12:15:15 <wumpus> it's starting to look more and more like a DoS with the sheer number of connections opened, though opening all those connections could also be a way to deceive the trickle logic
2212016-10-03T12:15:43 <wumpus> (and hence spy more effectively. I've never seen a spy that was so conspicious though...)
2222016-10-03T12:17:17 <sipa> seems those stopped connecting to me
2232016-10-03T12:18:17 <achow101> have you tried iptables to block those connections? I am about to do that.
2242016-10-03T12:19:20 <luke-jr> I suspect a human is watching us and filtering out our IPs when they figure out who we are
2252016-10-03T12:19:47 <wumpus> there's a topic on btctalk about it here: https://bitcointalk.org/index.php?topic=1478418.0
2262016-10-03T12:20:34 <wumpus> achow101: yes you can use iptables based blocking, or bitcoind's ban functionality, getting rid of them is quite easy

2282016-10-03T12:23:35 <wumpus> otherwise they leech quite some bandwith. "inv": 383977 * 45 connections, in 3 hours on one of my nodes
2292016-10-03T12:24:53 <wumpus> if it's a DoS it's a sneaky kind of DoS because they don't have to send you data, they don't send anything besides pong,verack and version, but they can just wait for you to send them tons of invs
2302016-10-03T12:25:40 <sipa> damn, since last thursday i've uploaded 250 GB worth of blocks
2312016-10-03T12:26:21 <wumpus> wow
2322016-10-03T12:27:09 <sipa> .. or my statistics patch is wrong
2332016-10-03T12:27:42 <wumpus> luke-jr: it's very possible for their operators to listen in here, yes
2342016-10-03T12:28:11 <sipa> or just notice they're getting banned and stop trying
2352016-10-03T12:30:16 <achow101> those are all Amazon IPs so we could report them to Amazon and see if they will stop them
2362016-10-03T12:30:30 <wumpus> yes, we should.

2392016-10-03T12:32:02 <wumpus> apparently they all suddenly reconnected about 300-400 seconds ago
2402016-10-03T12:35:41 <sipa> here as well
2412016-10-03T12:36:21 <wumpus> they're as conspicious as one can get, either this is some extremely unethical research project, or a troll action explicitly set up to provoke a response

3082016-10-03T15:29:10 <BlueMatt> or is that a big change to fix that small bug?

3212016-10-03T15:47:52 <sipa> BlueMatt: but that change will cause some logic to switch immediately in .13.1 rather than only after segwit activates

3282016-10-03T15:54:32 <sipa> BlueMatt: i think in general that it's fine to switch things based on segwit being defined rather than active
3292016-10-03T15:54:50 <sipa> as it will expose problems with relay earlier, and not all at once on the network
3302016-10-03T15:56:27 <BlueMatt> sipa: ok, I'll open a pr that does just that since it would be weird to have that in a compact block-related pr
3312016-10-03T15:57:57 <BlueMatt> fwiw, a brief glance indicates this same bug might exist in INV processing
3322016-10-03T16:07:08 <sipa> BlueMatt: we should have made inv-based announcements obsolete for cb and/or segwit
3332016-10-03T16:07:34 <BlueMatt> sipa: yea, I was just looking at that code, I really dont like it
3342016-10-03T16:07:55 <BlueMatt> sipa: i really want to rip out the request there and only respond with getheaders, but too late for 0.13.1

3962016-10-03T18:48:12 <sipa> i believe that is the only openssl dependency for bitcoind
3972016-10-03T18:49:25 <roasbeef> BlueMatt: gotcha, yeah that change should be fine from btcd's PoV

4042016-10-03T19:09:04 <instagibbs> isn't it used for payment protocol?
4052016-10-03T19:09:15 <instagibbs> or is that extra-bitcoind(i dont know that stuff)
4062016-10-03T19:09:22 <sipa> bitcoind does not support the payment protocol
4072016-10-03T19:09:32 <sipa> it's only in qt
4082016-10-03T19:09:35 <instagibbs> kk
4092016-10-03T19:09:44 <gmaxwell> yea my bitcoind qualification was intentional.

4682016-10-03T22:42:58 <luke-jr> meowzus: strictly easy, or as a good first stepping stone?
4692016-10-03T22:43:16 <meowzus> good first stepping stone most probably
4702016-10-03T22:43:35 <achow101> report bugs
4712016-10-03T22:44:27 <meowzus> i meant in terms of getting my hands with with developing

4762016-10-03T22:46:28 <sipa> do you know c++?
4772016-10-03T22:46:49 <meowzus> yeah
4782016-10-03T22:48:00 <achow101> meowzus: you can review open PRs
4792016-10-03T22:48:03 <luke-jr> meowzus: write new unit tests
4802016-10-03T22:48:08 <luke-jr> review is also helpful, yes

4842016-10-03T22:48:55 <sipa> meowzus: i suggest looking at the issue tracker (https://github.com/bitcoin/bitcoin/issues) and filtering for things with the 'easy' label
4852016-10-03T22:48:55 <luke-jr> sipa: perhaps, but boring and easy tend to overlap a lot, and tests and review help one learn the codebase well

4892016-10-03T22:50:44 <meowzus> luke-jr: how do i find out what unit tests are needed?
4902016-10-03T22:52:57 <luke-jr> meowzus: can either look over what exists already, or break things at random until something doesn't get detected
4912016-10-03T22:53:09 <meowzus> haha i see
4922016-10-03T22:53:32 <luke-jr> note some are in qa/rpc-tests/, some in src/tests/ and some in src/qt/tests/
4932016-10-03T22:53:47 <meowzus> cool
4942016-10-03T22:57:25 *** meowzus has quit IRC
4952016-10-03T23:01:43 <sipa> luke-jr: i generally believe that good unit tests require a thorough understanding of the behaviour that is being tested
4962016-10-03T23:02:04 <sipa> though it is true that it may help getting used to the codebase
4972016-10-03T23:02:06 <luke-jr> sipa: yes, I agree
4982016-10-03T23:02:17 <luke-jr> that's part of learning the codebase IMO
