113 2016-08-30T11:40:20  <jonasschnelli> What does "2016-08-29 20:22:53 socket send error Bad file descriptor (9)" mean? Running out of file descriptors?
114 2016-08-30T11:41:41  <jonasschnelli> One of my local node ran into this over night
115 2016-08-30T11:46:42  <wumpus> I don't think it's that, '9' isn't really a high number
116 2016-08-30T11:46:50  <wumpus> could be a use-after-close of some kind
117 2016-08-30T11:47:01  <jonasschnelli> It resulted in a shutdown at least
118 2016-08-30T11:47:27  <jonasschnelli> Also has bad allocs on the same machine.. could be memory related, though, its a brand new computer (means nothing, i know)
119 2016-08-30T11:47:51  <wumpus> ugh :/
120 2016-08-30T11:48:02  <jonasschnelli> DDR3L ram
121 2016-08-30T11:48:09  <wumpus> yes, memory corruption could definitely result in this, maybe the fd field was overwritten

124 2016-08-30T11:48:39  <wumpus> what do you exactly mean by 'bad allocs'?
125 2016-08-30T11:49:41  <jonasschnelli> bitcoind crashed with a std::expection bad alloc (I don't have the exact output right now)
126 2016-08-30T11:50:21  <jonasschnelli> Here we go:
127 2016-08-30T11:50:22  <jonasschnelli> EXCEPTION: St9bad_alloc
128 2016-08-30T11:50:22  <wumpus> that's running out of memory, not memory corruption
129 2016-08-30T11:50:31  <jonasschnelli> std::bad_alloc
130 2016-08-30T11:50:31  <jonasschnelli> bitcoin in ProcessMessages()
131 2016-08-30T11:50:37  <jonasschnelli> hmm....
132 2016-08-30T11:50:46  <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)
133 2016-08-30T11:50:50  <jonasschnelli> free -h --> total 16GB
134 2016-08-30T11:51:07  <wumpus> strange. Does it have swap enabled?
135 2016-08-30T11:51:11  <jonasschnelli> Headless debian with only bitcoind running..
136 2016-08-30T11:52:01  <wumpus> swap is extrememly important in Linux, even if you have enough memory, otherwise (AFAIK) it won't overcommit virtual memory and such
137 2016-08-30T11:52:16  <jonasschnelli> "free" tells me, mem: Total, 15GB, used 2.7GB (restarted node with -dbcache=4000), Swap: total 17GB, used 0GB
138 2016-08-30T11:52:29  <wumpus> okay, that's not it then
139 2016-08-30T11:52:37  <wumpus> really strange
140 2016-08-30T11:52:44  <jonasschnelli> The machine has 16GB physical memory... I don't think it ran out of memory
141 2016-08-30T11:52:49  <jonasschnelli> I keep en eye on that
142 2016-08-30T11:52:59  <wumpus> did you change dbcache?
143 2016-08-30T11:53:20  <jonasschnelli> Yes. Always ran with -dbache=4000
144 2016-08-30T11:53:27  <jonasschnelli> But codewise its pure master
145 2016-08-30T11:53:34  <jonasschnelli> at a5bb6387f751e630c329f34cac2d38bffa8ff9cf
146 2016-08-30T11:53:44  <wumpus> ok... no, that won't be the issue I think

148 2016-08-30T11:57:22  <jonasschnelli> Heres the debug log: http://paste.ubuntu.com/23111528/
149 2016-08-30T11:57:39  <jonasschnelli> Line 839 is the std::bad_alloc
150 2016-08-30T11:57:50  <jonasschnelli> then there are some socket send error Bad file descriptor (9)
151 2016-08-30T11:58:21  <jonasschnelli> Really strange the "Misbehaving: 85.214.213.91:8333 (0 -> 100) BAN THRESHOLD EXCEEDED" ... I hope its not an exploit.
152 2016-08-30T12:01:20  <wumpus> well I think the bad_alloc causes that rejection/banning
153 2016-08-30T12:01:35  <wumpus> it's unfortunate that we don't know which exact allocation failed
154 2016-08-30T12:03:08  <wumpus> apparently it's somewhere in the ConnectBlock() inputs logic
155 2016-08-30T12:04:42  <wumpus> 0000000000000000243ecc39a5c110fea174e34e4a2d00b5f2038ab2e2f5cf70  is the valid block at height 322006 - so if it was an exploit, it's not by sending a corrupted block
156 2016-08-30T12:05:03  <wumpus> kind of bad that a bad_alloc causes block rejection though
157 2016-08-30T12:05:22  <wumpus> after restarting you probably had to explicitly re-verify the block?
158 2016-08-30T12:06:31  <jonasschnelli> wumpus: I had to reindex at some point... IIRC, I had to do it afterwards.
159 2016-08-30T12:06:56  <jonasschnelli> But maybe the reindex was on a different datadir/run
160 2016-08-30T12:07:18  <jonasschnelli> At L912 is looks after a valid restart without reindex

264 2016-08-30T18:54:07  <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.
265 2016-08-30T18:54:19  <jeremyrubin> cfields: not under gdb
266 2016-08-30T18:54:55  <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
267 2016-08-30T18:55:10  <jeremyrubin> cfields: I tried adding "-static" to LDFLAGS
268 2016-08-30T18:55:47  <cfields> jeremyrubin: win32 builds are already static

270 2016-08-30T18:56:38  <cfields> jeremyrubin: i'm afraid i'm missing some context, though. Does the current bench code not work in win32?
271 2016-08-30T18:57:06  <jeremyrubin> cfields: I don't think so; let me test on master
272 2016-08-30T18:57:44  <jeremyrubin> cfields: where can I see the static flags? I don't think they're set for bench

284 2016-08-30T19:01:12  <cfields> ok. trying here too.
285 2016-08-30T19:01:24  <cfields> you're building with depends?

300 2016-08-30T19:08:43  <cfields> yea, we should aim to nuke those.
301 2016-08-30T19:09:34  <jeremyrubin> Yeah I can separately PR nuking them; pretty easy to remove that & the boost depends as well
302 2016-08-30T19:09:35  <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)
303 2016-08-30T19:10:01  <cfields> jeremyrubin: boost depends everywhere? or in bench?
304 2016-08-30T19:10:07  <jeremyrubin> in bench
305 2016-08-30T19:10:33  <jeremyrubin> I also had a theory that std::thread was the reason my builds were failing. Apparently std::thread support is shakey in wine?
306 2016-08-30T19:10:35  <cfields> ah, ok. that'll be nice to have :)
307 2016-08-30T19:10:55  <jeremyrubin> or rather in the x-compiler
308 2016-08-30T19:11:01  <jeremyrubin> seems to be fixed now though
309 2016-08-30T19:11:44  <jeremyrubin> can't wait to see the -death- removal of boost::thread
310 2016-08-30T19:11:46  <cfields> jeremyrubin: that'd be libstdc++. Surely it just uses win primitives under the hood, though
311 2016-08-30T19:12:17  <jeremyrubin> cfields: see https://github.com/meganz/mingw-std-threads
312 2016-08-30T19:12:44  <jeremyrubin> cfields: seems to be addressed though now; as when I compiled there was a version of std::thread present
313 2016-08-30T19:13:36  <jeremyrubin> cfields: also, forgot to mention that test_bitcoin.exe runs ok; so that was part of my inkling it was a build setting
314 2016-08-30T19:13:53  <cfields> jeremyrubin: i'm not sure what to say there, we rely on std::thread for mingw64 already
315 2016-08-30T19:14:12  <cfields> sounds like you're chasing all kinds of things :)

350 2016-08-30T21:29:33  <cfields> jeremyrubin: sure, sounds useful
351 2016-08-30T21:29:49  <cfields> jeremyrubin: but since it's already busted in master, no need to make it a blocker for anything else you're working on
352 2016-08-30T21:29:55  <jeremyrubin> cfields: Although looking at what's slow, it seems that PrevectorTestInt is really long on windows
353 2016-08-30T21:30:38  <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
354 2016-08-30T21:31:19  <cfields> jeremyrubin: by all means. last time i poked at that, it fought me hard. printing that would be great.
