295 2018-05-03T18:21:32  <wumpus> MarcoFalke: indeed, so used the full path to the source dir, and it works, no matter whether the current directory is in the build directory or the source one

297 2018-05-03T18:23:10  <wumpus> MarcoFalke: apparently I have a test/config.ini in the source dir, pointing to the BUILDDIR
298 2018-05-03T18:23:23  <wumpus> MarcoFalke: not sure this is the intention, will wipe it and reconfiguer
299 2018-05-03T18:23:26  <MarcoFalke> Yeah, otherwise it would fail
300 2018-05-03T18:23:39  <MarcoFalke> the config.ini is required now
301 2018-05-03T18:24:05  <wumpus> shouldn't it be in the build dir, though?
302 2018-05-03T18:24:46  <wumpus> to be clear I think this is convenient, but it probably breaks the case where one source directory is used with multiple build dirs

313 2018-05-03T18:43:05  <jamesob> cfields: would it make sense to at some point move logging into a separate thread? (about to look at your changes, but was just wondering)
314 2018-05-03T18:43:23  <wumpus> MarcoFalke: it looks like 'make clean' does not delete config.ini
315 2018-05-03T18:43:36  <MarcoFalke> oh
316 2018-05-03T18:43:39  <cfields> jamesob: yea, I think just about everyone has proposed that at some point, but nobody's done it :)
317 2018-05-03T18:43:40  <MarcoFalke> and make distclean?
318 2018-05-03T18:43:54  <wumpus> MarcoFalke: what happened is probably: I configured the source dir, cleaned that, then configured in a separate build directory
319 2018-05-03T18:44:08  <cfields> jamesob: might be a good topic for the meeting today, I'm sure there are lots of thoughts on that
320 2018-05-03T18:44:08  <jamesob> cfields: welp, I'll add it to the list :)

323 2018-05-03T18:44:26  <wumpus> distclean does remove it

434 2018-05-03T19:16:16  <BlueMatt> I did not propose it upstream as it means if we LogPrintf(); assert(false) we'll likely miss it

443 2018-05-03T19:16:50  <LukeJr> BlueMatt: surely there's a way to run log flushing at assert

445 2018-05-03T19:16:53  <promag> +1 BlueMatt point
446 2018-05-03T19:16:56  <cfields> are there any possible interactions where someone might be tailing the log and assume that it's synchronous?
447 2018-05-03T19:17:04  <jonasschnelli> use gdb
448 2018-05-03T19:17:15  <BlueMatt> wumpus: I mean the number of times its been helpful just to see which lines actually made it to debug.log when someone submitted a crash is super helpful
449 2018-05-03T19:17:21  <LukeJr> cfields: it couldn't be?
450 2018-05-03T19:17:25  <BlueMatt> and gdb isnt really an option when debugging remotely over github issues :/
451 2018-05-03T19:17:32  <jimpo> Does anyone know the relative performance of logging to console vs debug log file?
452 2018-05-03T19:17:50  <BlueMatt> jimpo: on non-serial-consoles, console logging should be fast, serial consoles can block
453 2018-05-03T19:17:54  <LukeJr> in theory, we could fork() a logging-only process, but that feels ugly
454 2018-05-03T19:17:56  <BlueMatt> (or vtt on a slow-refresh-monitor)
455 2018-05-03T19:17:59  <sipa> We should fork a separate process for logging, and then open a FIFO with it and pipe the log data there. If bitcoind crashes, that process hopefully survives :)

457 2018-05-03T19:18:03  <gribble> Error: "hi5" is not a valid command.
458 2018-05-03T19:18:17  <wumpus> it's mostly a win for low priority debugging messages, I guess
459 2018-05-03T19:18:21  <BlueMatt> or we could just make it optional
460 2018-05-03T19:18:26  <wumpus> if logging is low volume it's never a bottleneck
461 2018-05-03T19:18:35  <BlueMatt> miners can enable it, everyone else probably doesnt need to
462 2018-05-03T19:18:47  <wumpus> only miners that have debug=net enabled?
463 2018-05-03T19:18:51  <skeees> just throwing out some alternatives with a properly tuned buffer cache - logging shouldn't hit disk that often? if its still flushing frequently - could consider a more compact binary format for logs - though that means you'd need a special tool to read them
464 2018-05-03T19:19:18  <jimpo> I feel like disabling logging to file and piping stdout through tee or something should work fine
465 2018-05-03T19:19:38  <wumpus> skeees: well the logging is unbuffered at this moment so can't do much worse than that...
466 2018-05-03T19:19:38  <BlueMatt> wumpus: I mean -debug should always mean non-async loggin, I think
467 2018-05-03T19:19:50  <cfields> skeees: it's not just hitting disk, it's serialization as well. Though I guess we couldn't defer serialization if references are passed in.
468 2018-05-03T19:19:51  <wumpus> even line-buffered would be better for performance
469 2018-05-03T19:20:12  <jamesob> wumpus: I thought fwrite was buffered?
470 2018-05-03T19:20:12  <wumpus> BlueMatt: right
471 2018-05-03T19:20:15  <skeees> another option is to have debug logging compiled out
472 2018-05-03T19:20:25  <skeees> instead of just disabled via flag as it is currently
473 2018-05-03T19:20:30  <wumpus> jamesob: yes, but the buffer is disabled after opening
474 2018-05-03T19:20:40  <BlueMatt> I mean I dont think people who want performance dont want a debug.log
475 2018-05-03T19:20:48  <BlueMatt> they just dont want it to result in 8-ms pauses
476 2018-05-03T19:20:50  *** SopaXorzTaker has quit IRC
477 2018-05-03T19:21:00  <wumpus> skeees: that's not the issue; debug logging is already not executed if it's disabled
478 2018-05-03T19:21:03  * LukeJr wonders if we skip serialization when the debug log level is such that it will not be logged
479 2018-05-03T19:21:08  <wumpus> skeees: even formatting is bypassed in that case
480 2018-05-03T19:21:19  <wumpus> LukeJr: yes
481 2018-05-03T19:21:24  <skeees> LukeJr: yeah that's exactly the question i was trying to ask
482 2018-05-03T19:21:26  <skeees> ah ok
483 2018-05-03T19:21:58  <skeees> i dunno actually
484 2018-05-03T19:22:02  <wumpus> tbh I don't think there's an actual issue here
485 2018-05-03T19:22:09  <skeees> because theres a lot of uint256.ToString() stuff
486 2018-05-03T19:22:15  <cfields> operations on incoming vars aren't skipped though, I believe. Like LogPrint("foo: %s", foo.get())
487 2018-05-03T19:22:18  <BlueMatt> the only issue here is for folks who care a shitload about small disk pauses
488 2018-05-03T19:22:22  <wumpus> although the ring buffer would be nice because of gmaxwell's argument (log at higher debug message, but don't log the messages to disk unless a crash)
489 2018-05-03T19:22:22  <BlueMatt> hence why I use it in fibre
490 2018-05-03T19:22:58  <BlueMatt> when we get ReadBlockFromDisk to be async for peer handling, then it may make more sense to revisit this
491 2018-05-03T19:23:11  <wumpus> so a crash would log the last low-priority debug messages even if debugging is disabled.. then agian, it's not possible to bypass formatting anymore in that case
492 2018-05-03T19:23:25  <BlueMatt> we'd have to swap assert() for dump_log_and_crash()
493 2018-05-03T19:23:36  <wumpus> not sure that even requires logging to be in a sepaerate thread
494 2018-05-03T19:23:41  <LukeJr> wumpus: not sure if formatting is a big deal tbh
495 2018-05-03T19:23:50  <LukeJr> BlueMatt: or handle SIGABRT?
496 2018-05-03T19:23:51  <BlueMatt> no, but then I dont get to upstream my lockless ring buffer logger :p
497 2018-05-03T19:23:54  <wumpus> LukeJr: well some messages are extremely high volume
498 2018-05-03T19:24:01  <BlueMatt> luke-jr: I dont think we want to do that much work in a signal handler
499 2018-05-03T19:24:03  <wumpus> LukeJr: try enabling *all* debugging for fun

549 2018-05-03T19:32:27  <BlueMatt> ok, yes, I think that is doable, however, and I think between that and making progress on the standardness changes from jl2012 probably are worth a minor bump
550 2018-05-03T19:32:37  <skeees> there's also #12988 - which is a similar type of bug

552 2018-05-03T19:33:07  <BlueMatt> yes, indeed, that too
553 2018-05-03T19:33:18  <sdaftuar> agreed
554 2018-05-03T19:33:30  <wumpus> ok

560 2018-05-03T19:35:25  <BlueMatt> anyway, thats for discussion on that pr
561 2018-05-03T19:35:47  <BlueMatt> I'll ping jl2012 since he's probably asleep
562 2018-05-03T19:36:04  <BlueMatt> anyway, seems no disagreement, so next topic?
563 2018-05-03T19:36:06  <wumpus> yes, but it is the open PR with the most (ut)ACKs so I thought it'd be almost ready for merge
564 2018-05-03T19:36:34  <wumpus> that's why I rebased it with the idea to merge it after final review
565 2018-05-03T19:36:38  <wumpus> but ok
566 2018-05-03T19:36:54  <MarcoFalke> Yeah, would need some re-ACKs first, though
567 2018-05-03T19:37:19  <wumpus> right, but if the goalposts keep moving
568 2018-05-03T19:37:41  <wumpus> I think we've exhausted all proposed topics

574 2018-05-03T19:38:40  <gribble> https://github.com/bitcoin/bitcoin/issues/12934 | [WIP] [net] [validation] Call ProcessNewBlock() asynchronously by skeees · Pull Request #12934 · bitcoin/bitcoin · GitHub
575 2018-05-03T19:39:23  <BlueMatt> its certainly not ready for review, but we should maybe have a discussion about what concurrency across peers is gonna look like
576 2018-05-03T19:39:24  <wumpus> #topic Call ProcessNewBlock() asynchronously  (skeees)
577 2018-05-03T19:39:40  <BlueMatt> there are two main approaches, but both end up requiring similar refactors for the majority of their work
578 2018-05-03T19:39:51  <BlueMatt> in the past I've looked at doing ProcessMessages() in parallel
579 2018-05-03T19:40:07  <BlueMatt> in this pr skeees moves the validation processing of txn/blocks into a queue and does that in a separate thread
580 2018-05-03T19:40:31  <sipa> how does that interact with eg sending a ping after a block, and expecting it to be processed after the pong returns?
581 2018-05-03T19:40:34  <BlueMatt> in both cases, we end up building logic to "pause" processing of a peer until whatever message it just generated has been processed
582 2018-05-03T19:40:36  <wumpus> that sounds sensible, though I'm really afraid of c++ threading
583 2018-05-03T19:40:43  <BlueMatt> sipa: ^
584 2018-05-03T19:40:51  <gmaxwell> Seems like it would add more locking overhead.
585 2018-05-03T19:40:55  <BlueMatt> (which would also likely be useful for eg ReadBlockFromDisk moving to be more async)
586 2018-05-03T19:41:31  <sipa> sound reasonable to me
587 2018-05-03T19:41:32  <BlueMatt> and a ton of logic to move CNodeState out of cs_main (likely by creating a CNodeState2 during transision)
588 2018-05-03T19:41:43  <BlueMatt> cfields: may have more thoughts
589 2018-05-03T19:41:43  <sipa> that sounds even better
590 2018-05-03T19:41:48  <skeees> the other side benefit of this approach is that ultimately it may simplify the concurrency model inside validation
591 2018-05-03T19:41:53  <sipa> though everything depends on the details...
592 2018-05-03T19:42:06  <BlueMatt> gmaxwell: indeed, thats a major difference between the skeees approach and the parallel ProcessMessages approach
593 2018-05-03T19:42:09  <skeees> having a single thread processing from an ordered queue would have also solved the concurrency issues discussed before
594 2018-05-03T19:42:21  <BlueMatt> ProcessMessages will still do the work on the processing thread, which should have a bit less locking overhead
595 2018-05-03T19:42:21  <cfields> BlueMatt: just reading now. at a glance, this approach sounds similar to what I had in mind as well
596 2018-05-03T19:42:28  <BlueMatt> but is definitely more complicated than the skeees approach
597 2018-05-03T19:42:38  <BlueMatt> which draws a much cleaner boundary between validation and net_processing
598 2018-05-03T19:42:41  <gmaxwell> The biggest gain I'm aware of from concurrency is that right now when connecting multiple blocks at a time (due to out of order fetching in IBD) we stop downloading new blocks, ... fixing that would be a big gain; so it might be worth prioritizing improvements that would let that happen.
599 2018-05-03T19:42:54  <cfields> BlueMatt: I don't see why they'd be mutually exclusive?
600 2018-05-03T19:43:07  <BlueMatt> gmaxwell: that and relaying compact block gettxn during block connection
601 2018-05-03T19:43:25  <BlueMatt> which is the one big cheapish win left for block-relay-latency
602 2018-05-03T19:43:29  <gmaxwell> (e.g. esp when fetching from slow peers, watching network traffic during IBD is comical... transfering at only a couple mbps for a while then nothing for seconds at a time while it connects)
603 2018-05-03T19:43:34  <BlueMatt> cfields: well doing both is maybe not so useful
604 2018-05-03T19:43:54  <BlueMatt> since they'd accomplish largely the same thing
605 2018-05-03T19:44:11  *** leval2 has quit IRC
606 2018-05-03T19:44:13  <gmaxwell> BlueMatt: Fair enough for gettxn, though right now my own node makes almost no gettxn requests... and orphaning rates appear to be exceptionally low.
607 2018-05-03T19:44:30  <gmaxwell> (so what I'm saying is that at the moment I don't think of latency improvements as that critical)
608 2018-05-03T19:44:33  <BlueMatt> gmaxwell: the skeees approach is certainly better for doing things like deserialization of blocks coming in from other peers while calling ProcessNewBlock/ActivateBestChain
609 2018-05-03T19:44:52  <BlueMatt> indeed, right now (with mempool ~empty) compact block performance is ~perfect
610 2018-05-03T19:44:55  <BlueMatt> its not always so, however
611 2018-05-03T19:45:16  <gmaxwell> hm. interesting point that making deserialization concurrent would potentially be a multi-core gain.
612 2018-05-03T19:45:17  <BlueMatt> also, fibre nodes see more getblocktxn than miners
613 2018-05-03T19:45:17  <sipa> by "mempool ~empty" you mean "mempool is a perfect match" ?
614 2018-05-03T19:45:33  <BlueMatt> which would be equally solved by miners delaying 1 second before including new txn in blocks....
615 2018-05-03T19:45:54  <gmaxwell> sipa: if each block mostly clears the mempool, miner-specific prioritizaition of transactions doesn't cause as much surprise txn.
616 2018-05-03T19:46:13  <gmaxwell> BlueMatt: and also making use of the CB facility for transmitting extra txn proactively.
617 2018-05-03T19:46:24  <BlueMatt> yea, that too
618 2018-05-03T19:46:52  <BlueMatt> anyway, so tl;dr: I was a bigger fan of the skeees approach and wanted a little bit of concept discussion on the idea of putting a queue in front of the entire validation stuff
619 2018-05-03T19:46:59  <BlueMatt> since thats a huge departure from current operation
620 2018-05-03T19:47:10  <BlueMatt> but I think the potential gain is nice
621 2018-05-03T19:47:17  <BlueMatt> plus all our blocks are already passed in as shared_ptrs anyway.....
622 2018-05-03T19:47:21  <gmaxwell> so right my point was that speading up IBD is probably a big win, .. improving latency and what not would be nice too but I think it's less important.
623 2018-05-03T19:47:42  <LukeJr> +1
624 2018-05-03T19:47:43  <BlueMatt> yes, right now that is definitely true
625 2018-05-03T19:47:51  <BlueMatt> certainly this has the potential to address both, however
626 2018-05-03T19:47:56  <gmaxwell> making use of more cores during sync would be nice too, e.g. if deserilization and hashing can happen on seperate threads async with connection.
627 2018-05-03T19:48:13  <BlueMatt> we can do CheckBlock on the net_processing thread
628 2018-05-03T19:48:27  <BlueMatt> (since, and sipa is gonna die a little bit inside, here, the result is cached in the CBlock structure)
629 2018-05-03T19:48:44  <sdaftuar> that is kinda gross :)
630 2018-05-03T19:48:52  <BlueMatt> its incredibly gross
631 2018-05-03T19:48:59  <gmaxwell> (e.g. multiple message handling threads, which do deserialization and maybe stateless checks)
632 2018-05-03T19:49:21  <wumpus> oh no...
633 2018-05-03T19:49:24  <bitcoin-git> [bitcoin] practicalswift opened pull request #13163: Make it clear which functions that are intended to be translation unit local (master...internal-linkage) https://github.com/bitcoin/bitcoin/pull/13163
634 2018-05-03T19:49:51  <gmaxwell> though I did a dumb hack a while back that reordered some of the block validation steps to interleave checks that operate per transaction and got a few percent sync speed improvement... we should be mindful of memory locality and not introduce even more passes over blocks.
635 2018-05-03T19:50:05  <BlueMatt> gmaxwell: dunno about multiple message handling threads being doable in the immediate future, but doing CheckBlock on the message processing thread (which does merkle root verification, which is a good chunk of the work) may be worth a chunk
636 2018-05-03T19:50:27  <skeees> cool - so if no strong objections or concerns with the approach i'll continue this and come back when its more ready for review
637 2018-05-03T19:51:07  <gmaxwell> Funny, I would have thought handling seperate peers in seperate threads would almost just work now, vs stuff that handled messages from the same peer concurrently, which violates protocol assumptions about ordering without special work to add processing barriers.
638 2018-05-03T19:51:25  <BlueMatt> gmaxwell: CNodeState requires cs_main, so....not even close :(
639 2018-05-03T19:51:40  <gmaxwell> (almost just work, because the critical data structues have locks ... oh CNodeState)
640 2018-05-03T19:51:45  <BlueMatt> I've got some old branches that do that, if you want to look
641 2018-05-03T19:51:47  <gmaxwell> cs_main lite.
642 2018-05-03T19:51:50  <BlueMatt> but they're....not small changes
643 2018-05-03T19:52:03  <BlueMatt> and cfields hates them, though he's probably right
644 2018-05-03T19:52:26  <BlueMatt> anyway, so </topic> </meeting> ["DIE", "XML"]?
645 2018-05-03T19:52:29  <gmaxwell> in particular our most commons messages are transaction invs and get datas, and those should only need mempool stuff for much of their activity.
646 2018-05-03T19:52:36  <gmaxwell> k.
647 2018-05-03T19:52:44  <BlueMatt> gmaxwell: yes, I did all that in an old branch
648 2018-05-03T19:52:51  <BlueMatt> that in particular is much closer than it used to be
649 2018-05-03T19:53:00  <BlueMatt> cause now the HandleGetData stuff cant take cs_main at the top
650 2018-05-03T19:53:10  <BlueMatt> IIRC that refactor landed for 0.16

666 2018-05-03T19:58:58  <BlueMatt> and if we took the "split CNodeState" approach instead of "pull CNodeState above cs_main in global lock order and give it its own lock all in one go" approach that that branch takes, it'd likely be wayyy simpler

721 2018-05-03T23:39:10  <jamesob> cfields: oh no not at all! sorry if the PR close came off as me being upset
722 2018-05-03T23:40:14  <jamesob> cfields: I just like your commits better :). Maybe I can cherry-pick them and then shuffle in my GetProcessName/SetProcessName stuff + some tests
723 2018-05-03T23:40:50  <jamesob> if that sounds good, would it make sense to repurpose that same PR or open a new one?

725 2018-05-03T23:44:33  <cfields> jamesob: ok, good
726 2018-05-03T23:45:14  <cfields> jamesob: if you're going to do away with the suffix handling, I'd say just do a new PR
727 2018-05-03T23:45:50  <cfields> jamesob: either way, my code is all yours if you like it

729 2018-05-03T23:53:30  <jamesob> cfields: yeah, should be easy to incorporate the suffix stuff inline as you suggest
730 2018-05-03T23:57:10  <jamesob> just felt embarrassed I didn't see that earlier :)
