04:40 < jonasschnelli> What does "2016-08-29 20:22:53 socket send error Bad file descriptor (9)" mean? Running out of file descriptors?
04:41 < jonasschnelli> One of my local node ran into this over night
04:46 < wumpus> I don't think it's that, '9' isn't really a high number
04:46 < wumpus> could be a use-after-close of some kind
04:47 < jonasschnelli> It resulted in a shutdown at least
04:47 < jonasschnelli> Also has bad allocs on the same machine.. could be memory related, though, its a brand new computer (means nothing, i know)
04:47 < wumpus> ugh :/
04:48 < jonasschnelli> DDR3L ram
04:48 < wumpus> yes, memory corruption could definitely result in this, maybe the fd field was overwritten

04:48 < wumpus> what do you exactly mean by 'bad allocs'?
04:49 < jonasschnelli> bitcoind crashed with a std::expection bad alloc (I don't have the exact output right now)
04:50 < jonasschnelli> Here we go:
04:50 < jonasschnelli> EXCEPTION: St9bad_alloc   
04:50 < wumpus> that's running out of memory, not memory corruption
04:50 < jonasschnelli> std::bad_alloc
04:50 < jonasschnelli> bitcoin in ProcessMessages()
04:50 < jonasschnelli> hmm....
04:50 < wumpus> (well it can be memory corruption if the heap's administractive structures are corrupted, however that much more likely results in a segmentation fault)
04:50 < jonasschnelli> free -h --> total 16GB
04:51 < wumpus> strange. Does it have swap enabled?
04:51 < jonasschnelli> Headless debian with only bitcoind running..
04:52 < wumpus> swap is extrememly important in Linux, even if you have enough memory, otherwise (AFAIK) it won't overcommit virtual memory and such
04:52 < jonasschnelli> "free" tells me, mem: Total, 15GB, used 2.7GB (restarted node with -dbcache=4000), Swap: total 17GB, used 0GB
04:52 < wumpus> okay, that's not it then
04:52 < wumpus> really strange
04:52 < jonasschnelli> The machine has 16GB physical memory... I don't think it ran out of memory
04:52 < jonasschnelli> I keep en eye on that
04:52 < wumpus> did you change dbcache?
04:53 < jonasschnelli> Yes. Always ran with -dbache=4000
04:53 < jonasschnelli> But codewise its pure master
04:53 < jonasschnelli> at a5bb6387f751e630c329f34cac2d38bffa8ff9cf
04:53 < wumpus> ok... no, that won't be the issue I think
04:54 -!- dcousens [~anon@c110-22-219-15.sunsh4.vic.optusnet.com.au] has joined #bitcoin-core-dev
04:57 < jonasschnelli> Heres the debug log: http://paste.ubuntu.com/23111528/
04:57 < jonasschnelli> Line 839 is the std::bad_alloc
04:57 < jonasschnelli> then there are some socket send error Bad file descriptor (9)
04:58 < jonasschnelli> Really strange the "Misbehaving: 85.214.213.91:8333 (0 -> 100) BAN THRESHOLD EXCEEDED" ... I hope its not an exploit.
05:01 < wumpus> well I think the bad_alloc causes that rejection/banning
05:01 < wumpus> it's unfortunate that we don't know which exact allocation failed
05:03 < wumpus> apparently it's somewhere in the ConnectBlock() inputs logic
05:04 < wumpus> 0000000000000000243ecc39a5c110fea174e34e4a2d00b5f2038ab2e2f5cf70  is the valid block at height 322006 - so if it was an exploit, it's not by sending a corrupted block
05:05 < wumpus> kind of bad that a bad_alloc causes block rejection though
05:05 < wumpus> after restarting you probably had to explicitly re-verify the block?
05:06 < jonasschnelli> wumpus: I had to reindex at some point... IIRC, I had to do it afterwards.
05:06 < jonasschnelli> But maybe the reindex was on a different datadir/run
05:07 < jonasschnelli> At L912 is looks after a valid restart without reindex

11:53 < cfields> jeremyrubin: errors running? or running under gdb? 'cause wine+gdb is a different beast :)
11:54 < jeremyrubin> cfields: there are two main issues. The first is the sys/time.h depends. I removed that for a std::chrono solution (can send you code) then, removing all test code, and by removing all the boost dependencies (replacing with standard way), I can run just the benchmarking framework.
11:54 < jeremyrubin> cfields: not under gdb
11:54 < jeremyrubin> cfields: adding the benchmarks back I can run again, so i'm doing a "bisect" on which of the benchmarks is causing the loading fault now, but I think it's link time because it doesn't even run
11:55 < jeremyrubin> cfields: I tried adding "-static" to LDFLAGS
11:55 < cfields> jeremyrubin: win32 builds are already static
11:56  * jonasschnelli setups mingw32 depends builds
11:56 < cfields> jeremyrubin: i'm afraid i'm missing some context, though. Does the current bench code not work in win32?
11:57 < jeremyrubin> cfields: I don't think so; let me test on master
11:57 < jeremyrubin> cfields: where can I see the static flags? I don't think they're set for bench
11:58 < cfields> jeremyrubin: ah, ok
11:58 < cfields> jeremyrubin: they're kinda a maze, sec

12:01 < cfields> ok. trying here too.
12:01 < cfields> you're building with depends?

12:08 < jeremyrubin> (not sure if the sys/time.h include is problematic)
12:08 < cfields> yea, we should aim to nuke those.
12:09 < jeremyrubin> Yeah I can separately PR nuking them; pretty easy to remove that & the boost depends as well
12:09 < cfields> (i'll be PR'ing my threading refactor in a few hours which will let us kill off a ton of boost stuff, chrono included)
12:10 < cfields> jeremyrubin: boost depends everywhere? or in bench?
12:10 < jeremyrubin> in bench
12:10 < jeremyrubin> I also had a theory that std::thread was the reason my builds were failing. Apparently std::thread support is shakey in wine?
12:10 < cfields> ah, ok. that'll be nice to have :)
12:10 < jeremyrubin> or rather in the x-compiler
12:11 < jeremyrubin> seems to be fixed now though
12:11 < jeremyrubin> can't wait to see the -death- removal of boost::thread
12:11 < cfields> jeremyrubin: that'd be libstdc++. Surely it just uses win primitives under the hood, though
12:12 < jeremyrubin> cfields: see https://github.com/meganz/mingw-std-threads
12:12 < jeremyrubin> cfields: seems to be addressed though now; as when I compiled there was a version of std::thread present
12:13 < jeremyrubin> cfields: also, forgot to mention that test_bitcoin.exe runs ok; so that was part of my inkling it was a build setting
12:13 < cfields> jeremyrubin: i'm not sure what to say there, we rely on std::thread for mingw64 already
12:14 < cfields> sounds like you're chasing all kinds of things :)

14:28 < cfields> ok
14:29 < jeremyrubin> cfields: I guess it's not the most critical thing to fix, but I wanted to make travis print out benchmarking info in case tests are timing out due to poor performance will help debugging 
14:29 < cfields> jeremyrubin: sure, sounds useful
14:29 < cfields> jeremyrubin: but since it's already busted in master, no need to make it a blocker for anything else you're working on
14:29 < jeremyrubin> cfields: Although looking at what's slow, it seems that PrevectorTestInt is really long on windows
14:30 < jeremyrubin> cfields: So I'm thinking about also changing the build_aux test driver to tee the log and print out the test messages so that it can see what it timed out on
14:31 < cfields> jeremyrubin: by all means. last time i poked at that, it fought me hard. printing that would be great.
14:32 < jeremyrubin> cfields: yeah I've spent the morning mucking through automake crap 
14:33 < jeremyrubin> cfields: in any case; the current build system is functionally broken because if you add tests that make it go over 10 min it breaks :)

21:10 < achow101> I don't think that really fits what I am trying to do
21:11 < achow101> the idea is that the user should be able to just start Bitcoin Core with no options (except server=1 I guess) and the software (Armory) would be able to automatically know how to connect to the server without any user input
21:11 < achow101> it seems that cookie auth is best for this since the cookie is automatically generated
21:12 < gmaxwell> thats what the cookie auth is for.

21:13 < gmaxwell> Currently it lodges a complaint in the debug.log.
