2952018-05-03T18:21:32  <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
2962018-05-03T18:22:09  *** tryphe has quit IRC
2972018-05-03T18:23:10  <wumpus> MarcoFalke: apparently I have a test/config.ini in the source dir, pointing to the BUILDDIR
2982018-05-03T18:23:23  <wumpus> MarcoFalke: not sure this is the intention, will wipe it and reconfiguer
2992018-05-03T18:23:26  <MarcoFalke> Yeah, otherwise it would fail
3002018-05-03T18:23:39  <MarcoFalke> the config.ini is required now
3012018-05-03T18:24:05  <wumpus> shouldn't it be in the build dir, though?
3022018-05-03T18:24:46  <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

3132018-05-03T18:43:05  <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)
3142018-05-03T18:43:23  <wumpus> MarcoFalke: it looks like 'make clean' does not delete config.ini
3152018-05-03T18:43:36  <MarcoFalke> oh
3162018-05-03T18:43:39  <cfields> jamesob: yea, I think just about everyone has proposed that at some point, but nobody's done it :)
3172018-05-03T18:43:40  <MarcoFalke> and make distclean?
3182018-05-03T18:43:54  <wumpus> MarcoFalke: what happened is probably: I configured the source dir, cleaned that, then configured in a separate build directory
3192018-05-03T18:44:08  <cfields> jamesob: might be a good topic for the meeting today, I'm sure there are lots of thoughts on that
3202018-05-03T18:44:08  <jamesob> cfields: welp, I'll add it to the list :)

3692018-05-03T19:05:22  <jnewbery> There's a whole series of sequential PRs on wallet load/create/unload. It'd be good to start moving through those, but I don't know how high priority they are for others
3702018-05-03T19:05:42  <wumpus> jnewbery: if it's blocking anyone, the first one on the list should be on there at least
3712018-05-03T19:05:48  <jtimon> perhaps put the load one in high priority?

3742018-05-03T19:06:14  <jnewbery> It's only blocking because there are other ones queued behind it
3752018-05-03T19:06:25  <BlueMatt> jnewbery: that is the most common form of blocking
3762018-05-03T19:06:26  <wumpus> so it's blocking the continuation ones
3772018-05-03T19:06:33  <jimpo> That's basically the definition of blocking...
3782018-05-03T19:06:35  <wumpus> right, it's pretty much the definition of blocking
3792018-05-03T19:06:37  <wumpus> lol
3802018-05-03T19:06:39  <jonasschnelli> I agree that we should add 10740 to the list

4342018-05-03T19:16:16  <BlueMatt> I did not propose it upstream as it means if we LogPrintf(); assert(false) we'll likely miss it

4392018-05-03T19:16:39  <BlueMatt> jnewbery: it still will be a ton cause it ReadBlockFromDisk()s
4402018-05-03T19:16:40  <wumpus> BlueMatt: we could have special priority log calls that always make it to disk?

4422018-05-03T19:16:46  <jamesob> skeees: right, I think that's the only caveat I can think of
4432018-05-03T19:16:50  <LukeJr> BlueMatt: surely there's a way to run log flushing at assert
4442018-05-03T19:16:53  <wumpus> BlueMatt: CriticalLogPrintf?
4452018-05-03T19:16:53  <promag> +1 BlueMatt point
4462018-05-03T19:16:56  <cfields> are there any possible interactions where someone might be tailing the log and assume that it's synchronous?
4472018-05-03T19:17:04  <jonasschnelli> use gdb
4482018-05-03T19:17:15  <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
4492018-05-03T19:17:21  <LukeJr> cfields: it couldn't be?
4502018-05-03T19:17:25  <BlueMatt> and gdb isnt really an option when debugging remotely over github issues :/
4512018-05-03T19:17:32  <jimpo> Does anyone know the relative performance of logging to console vs debug log file?
4522018-05-03T19:17:50  <BlueMatt> jimpo: on non-serial-consoles, console logging should be fast, serial consoles can block
4532018-05-03T19:17:54  <LukeJr> in theory, we could fork() a logging-only process, but that feels ugly
4542018-05-03T19:17:56  <BlueMatt> (or vtt on a slow-refresh-monitor)
4552018-05-03T19:17:59  <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 :)

4572018-05-03T19:18:03  <gribble> Error: "hi5" is not a valid command.
4582018-05-03T19:18:17  <wumpus> it's mostly a win for low priority debugging messages, I guess
4592018-05-03T19:18:21  <BlueMatt> or we could just make it optional
4602018-05-03T19:18:26  <wumpus> if logging is low volume it's never a bottleneck
4612018-05-03T19:18:35  <BlueMatt> miners can enable it, everyone else probably doesnt need to
4622018-05-03T19:18:47  <wumpus> only miners that have debug=net enabled?
4632018-05-03T19:18:51  <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
4642018-05-03T19:19:18  <jimpo> I feel like disabling logging to file and piping stdout through tee or something should work fine
4652018-05-03T19:19:38  <wumpus> skeees: well the logging is unbuffered at this moment so can't do much worse than that...
4662018-05-03T19:19:38  <BlueMatt> wumpus: I mean -debug should always mean non-async loggin, I think
4672018-05-03T19:19:50  <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.
4682018-05-03T19:19:51  <wumpus> even line-buffered would be better for performance
4692018-05-03T19:20:12  <jamesob> wumpus: I thought fwrite was buffered?
4702018-05-03T19:20:12  <wumpus> BlueMatt: right
4712018-05-03T19:20:15  <skeees> another option is to have debug logging compiled out
4722018-05-03T19:20:25  <skeees> instead of just disabled via flag as it is currently
4732018-05-03T19:20:30  <wumpus> jamesob: yes, but the buffer is disabled after opening
4742018-05-03T19:20:40  <BlueMatt> I mean I dont think people who want performance dont want a debug.log
4752018-05-03T19:20:48  <BlueMatt> they just dont want it to result in 8-ms pauses
4762018-05-03T19:20:50  *** SopaXorzTaker has quit IRC
4772018-05-03T19:21:00  <wumpus> skeees: that's not the issue; debug logging is already not executed if it's disabled
4782018-05-03T19:21:03  * LukeJr wonders if we skip serialization when the debug log level is such that it will not be logged
4792018-05-03T19:21:08  <wumpus> skeees: even formatting is bypassed in that case
4802018-05-03T19:21:19  <wumpus> LukeJr: yes
4812018-05-03T19:21:24  <skeees> LukeJr: yeah that's exactly the question i was trying to ask
4822018-05-03T19:21:26  <skeees> ah ok
4832018-05-03T19:21:58  <skeees> i dunno actually
4842018-05-03T19:22:02  <wumpus> tbh I don't think there's an actual issue here
4852018-05-03T19:22:09  <skeees> because theres a lot of uint256.ToString() stuff
4862018-05-03T19:22:15  <cfields> operations on incoming vars aren't skipped though, I believe. Like LogPrint("foo: %s", foo.get())
4872018-05-03T19:22:18  <BlueMatt> the only issue here is for folks who care a shitload about small disk pauses
4882018-05-03T19:22:22  <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)
4892018-05-03T19:22:22  <BlueMatt> hence why I use it in fibre
4902018-05-03T19:22:58  <BlueMatt> when we get ReadBlockFromDisk to be async for peer handling, then it may make more sense to revisit this
4912018-05-03T19:23:11  <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
4922018-05-03T19:23:25  <BlueMatt> we'd have to swap assert() for dump_log_and_crash()
4932018-05-03T19:23:36  <wumpus> not sure that even requires logging to be in a sepaerate thread
4942018-05-03T19:23:41  <LukeJr> wumpus: not sure if formatting is a big deal tbh
4952018-05-03T19:23:50  <LukeJr> BlueMatt: or handle SIGABRT?
4962018-05-03T19:23:51  <BlueMatt> no, but then I dont get to upstream my lockless ring buffer logger :p
4972018-05-03T19:23:54  <wumpus> LukeJr: well some messages are extremely high volume
4982018-05-03T19:24:01  <BlueMatt> luke-jr: I dont think we want to do that much work in a signal handler
4992018-05-03T19:24:03  <wumpus> LukeJr: try enabling *all* debugging for fun

5322018-05-03T19:30:21  <BlueMatt> cause they're threading issues they almost certainly wont effect anyone except submitblock users

5342018-05-03T19:30:42  <BlueMatt> but, still, I think given that and some of the other various fixes we've had, it may be worth backporting
5352018-05-03T19:31:11  <wumpus> 13092 is an issue, not a PR, can't label it for backport

5612018-05-03T19:35:47  <BlueMatt> I'll ping jl2012 since he's probably asleep
5622018-05-03T19:36:04  <BlueMatt> anyway, seems no disagreement, so next topic?
5632018-05-03T19:36:06  <wumpus> yes, but it is the open PR with the most (ut)ACKs so I thought it'd be almost ready for merge
5642018-05-03T19:36:34  <wumpus> that's why I rebased it with the idea to merge it after final review
5652018-05-03T19:36:38  <wumpus> but ok
5662018-05-03T19:36:54  <MarcoFalke> Yeah, would need some re-ACKs first, though
5672018-05-03T19:37:19  <wumpus> right, but if the goalposts keep moving
5682018-05-03T19:37:41  <wumpus> I think we've exhausted all proposed topics

5712018-05-03T19:38:21  <BlueMatt> oh, no, wait i had another topic
5722018-05-03T19:38:34  <BlueMatt> topic: activate segwit
5732018-05-03T19:38:38  <BlueMatt> topic 2: <BlueMatt>  #12934
5742018-05-03T19:38:40  <gribble> https://github.com/bitcoin/bitcoin/issues/12934 | [WIP] [net] [validation] Call ProcessNewBlock() asynchronously by skeees · Pull Request #12934 · bitcoin/bitcoin · GitHub
5752018-05-03T19:39:23  <BlueMatt> its certainly not ready for review, but we should maybe have a discussion about what concurrency across peers is gonna look like
5762018-05-03T19:39:24  <wumpus> #topic Call ProcessNewBlock() asynchronously  (skeees)
5772018-05-03T19:39:40  <BlueMatt> there are two main approaches, but both end up requiring similar refactors for the majority of their work
5782018-05-03T19:39:51  <BlueMatt> in the past I've looked at doing ProcessMessages() in parallel
5792018-05-03T19:40:07  <BlueMatt> in this pr skeees moves the validation processing of txn/blocks into a queue and does that in a separate thread
5802018-05-03T19:40:31  <sipa> how does that interact with eg sending a ping after a block, and expecting it to be processed after the pong returns?
5812018-05-03T19:40:34  <BlueMatt> in both cases, we end up building logic to "pause" processing of a peer until whatever message it just generated has been processed
5822018-05-03T19:40:36  <wumpus> that sounds sensible, though I'm really afraid of c++ threading
5832018-05-03T19:40:43  <BlueMatt> sipa: ^
5842018-05-03T19:40:51  <gmaxwell> Seems like it would add more locking overhead.
5852018-05-03T19:40:55  <BlueMatt> (which would also likely be useful for eg ReadBlockFromDisk moving to be more async)
5862018-05-03T19:41:31  <sipa> sound reasonable to me
5872018-05-03T19:41:32  <BlueMatt> and a ton of logic to move CNodeState out of cs_main (likely by creating a CNodeState2 during transision)
5882018-05-03T19:41:43  <BlueMatt> cfields: may have more thoughts
5892018-05-03T19:41:43  <sipa> that sounds even better
5902018-05-03T19:41:48  <skeees> the other side benefit of this approach is that ultimately it may simplify the concurrency model inside validation
5912018-05-03T19:41:53  <sipa> though everything depends on the details...
5922018-05-03T19:42:06  <BlueMatt> gmaxwell: indeed, thats a major difference between the skeees approach and the parallel ProcessMessages approach
5932018-05-03T19:42:09  <skeees> having a single thread processing from an ordered queue would have also solved the concurrency issues discussed before
5942018-05-03T19:42:21  <BlueMatt> ProcessMessages will still do the work on the processing thread, which should have a bit less locking overhead
5952018-05-03T19:42:21  <cfields> BlueMatt: just reading now. at a glance, this approach sounds similar to what I had in mind as well
5962018-05-03T19:42:28  <BlueMatt> but is definitely more complicated than the skeees approach
5972018-05-03T19:42:38  <BlueMatt> which draws a much cleaner boundary between validation and net_processing
5982018-05-03T19:42:41  <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.
5992018-05-03T19:42:54  <cfields> BlueMatt: I don't see why they'd be mutually exclusive?
6002018-05-03T19:43:07  <BlueMatt> gmaxwell: that and relaying compact block gettxn during block connection
6012018-05-03T19:43:25  <BlueMatt> which is the one big cheapish win left for block-relay-latency
6022018-05-03T19:43:29  <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)
6032018-05-03T19:43:34  <BlueMatt> cfields: well doing both is maybe not so useful
6042018-05-03T19:43:54  <BlueMatt> since they'd accomplish largely the same thing
6052018-05-03T19:44:11  *** leval2 has quit IRC
6062018-05-03T19:44:13  <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.
6072018-05-03T19:44:30  <gmaxwell> (so what I'm saying is that at the moment I don't think of latency improvements as that critical)
6082018-05-03T19:44:33  <BlueMatt> gmaxwell: the skeees approach is certainly better for doing things like deserialization of blocks coming in from other peers while calling ProcessNewBlock/ActivateBestChain
6092018-05-03T19:44:52  <BlueMatt> indeed, right now (with mempool ~empty) compact block performance is ~perfect
6102018-05-03T19:44:55  <BlueMatt> its not always so, however
6112018-05-03T19:45:16  <gmaxwell> hm. interesting point that making deserialization concurrent would potentially be a multi-core gain.
6122018-05-03T19:45:17  <BlueMatt> also, fibre nodes see more getblocktxn than miners
6132018-05-03T19:45:17  <sipa> by "mempool ~empty" you mean "mempool is a perfect match" ?
6142018-05-03T19:45:33  <BlueMatt> which would be equally solved by miners delaying 1 second before including new txn in blocks....
6152018-05-03T19:45:54  <gmaxwell> sipa: if each block mostly clears the mempool, miner-specific prioritizaition of transactions doesn't cause as much surprise txn.
6162018-05-03T19:46:13  <gmaxwell> BlueMatt: and also making use of the CB facility for transmitting extra txn proactively.
6172018-05-03T19:46:24  <BlueMatt> yea, that too
6182018-05-03T19:46:52  <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
6192018-05-03T19:46:59  <BlueMatt> since thats a huge departure from current operation
6202018-05-03T19:47:10  <BlueMatt> but I think the potential gain is nice
6212018-05-03T19:47:17  <BlueMatt> plus all our blocks are already passed in as shared_ptrs anyway.....
6222018-05-03T19:47:21  <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.
6232018-05-03T19:47:42  <LukeJr> +1
6242018-05-03T19:47:43  <BlueMatt> yes, right now that is definitely true
6252018-05-03T19:47:51  <BlueMatt> certainly this has the potential to address both, however
6262018-05-03T19:47:56  <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.
6272018-05-03T19:48:13  <BlueMatt> we can do CheckBlock on the net_processing thread
6282018-05-03T19:48:27  <BlueMatt> (since, and sipa is gonna die a little bit inside, here, the result is cached in the CBlock structure)
6292018-05-03T19:48:44  <sdaftuar> that is kinda gross :)
6302018-05-03T19:48:52  <BlueMatt> its incredibly gross
6312018-05-03T19:48:59  <gmaxwell> (e.g. multiple message handling threads, which do deserialization and maybe stateless checks)
6322018-05-03T19:49:21  <wumpus> oh no...
6332018-05-03T19:49:24  <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
6342018-05-03T19:49:51  <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.
6352018-05-03T19:50:05  <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
6362018-05-03T19:50:27  <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
6372018-05-03T19:51:07  <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.
6382018-05-03T19:51:25  <BlueMatt> gmaxwell: CNodeState requires cs_main, so....not even close :(
6392018-05-03T19:51:40  <gmaxwell> (almost just work, because the critical data structues have locks ... oh CNodeState)
6402018-05-03T19:51:45  <BlueMatt> I've got some old branches that do that, if you want to look
6412018-05-03T19:51:47  <gmaxwell> cs_main lite.
6422018-05-03T19:51:50  <BlueMatt> but they're....not small changes
6432018-05-03T19:52:03  <BlueMatt> and cfields hates them, though he's probably right
6442018-05-03T19:52:26  <BlueMatt> anyway, so </topic> </meeting> ["DIE", "XML"]?
6452018-05-03T19:52:29  <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.
6462018-05-03T19:52:36  <gmaxwell> k.
6472018-05-03T19:52:44  <BlueMatt> gmaxwell: yes, I did all that in an old branch
6482018-05-03T19:52:51  <BlueMatt> that in particular is much closer than it used to be
6492018-05-03T19:53:00  <BlueMatt> cause now the HandleGetData stuff cant take cs_main at the top
6502018-05-03T19:53:10  <BlueMatt> IIRC that refactor landed for 0.16

6622018-05-03T19:57:44  <gmaxwell> I think it would be simpler now, a lot of changes in the last year would have made it easier (I say this without having recently looked at that branch)

6652018-05-03T19:58:26  <BlueMatt> rather significantly
6662018-05-03T19:58:58  <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
