Also, if you go back to IRC logs around that same time (end of august), you should be able to find some info I said there about the same problem

   5 2016-10-18T00:09:30  <michagogo> achow101: hmm. I seem to remember (from quite a while back…) that I tried doing it on Xenial and failed too
   6 2016-10-18T00:10:08  <michagogo> I feel like I might have gotten past the shm thing just to have it fail a different way
   7 2016-10-18T00:10:14  <michagogo> Or maybe I'm misremembering
   8 2016-10-18T00:10:32  <michagogo> Works for me on the Trusty Tahr, though
   9 2016-10-18T00:11:19  * sipa realizes that he never knew what the part after 'Trusty' in the ubuntu version name was
  10 2016-10-18T00:11:43  <achow101> Maybe I'll try it in a VM with trusty then. I've been running 16.04 which is what I do the builds on
  11 2016-10-18T00:11:58  <achow101> it previously worked on 15.10 for a while then broke

  21 2016-10-18T00:51:26  <achow101> it is failing at installing stuff. the install.log says "E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution)."

  60 2016-10-18T02:03:52  <gmaxwell> I have one node that after being upgraded, run for three houres, and restart... has no nodewitness peers.
  61 2016-10-18T02:03:59  <gmaxwell> (thus the PR that I opened)
  62 2016-10-18T02:04:12  <tulip> gmaxwell: that's with your patch.
  63 2016-10-18T02:04:16  <gmaxwell> ah okay!
  64 2016-10-18T02:04:23  <tulip> it had no NODE_WITNESS peers beforehand.
  65 2016-10-18T02:04:41  <gmaxwell> yea, with the patch it will be pretty much guarenteed to find some... often 4. :)
  66 2016-10-18T02:05:35  <tulip> curious why we are even trying to connect to nodes with port zero, is anyone really going to be running a privileged port Bitcoin node?
  67 2016-10-18T02:06:04  <tulip> (I assumed 0-1023 would be masked out entirely)
  68 2016-10-18T02:06:13  <gmaxwell> well we only try connecting to non-standard ports if we've been failing to connect for a while, but port 0 is braindamaged.
  69 2016-10-18T02:06:55  <gmaxwell> someone might plausably run a bitcoin node on port 80 or port 443 since it's a little more likely to make it through firewalls.
  70 2016-10-18T02:08:09  <gmaxwell> port 0 is just stupid though. We should probably filter out port 0 from ever going into addrman.

  79 2016-10-18T03:27:44  <morcos> gmaxwell: at the risk of beating a dead horse, can you try again to explain to me the logic behind writing down the mempool every 10 mins?
  80 2016-10-18T03:28:04  <gmaxwell> every ten minutes I care less about than at clean shutdown.
  81 2016-10-18T03:28:07  *** mol has quit IRC
  82 2016-10-18T03:28:11  <morcos> i can somewhat reluctantly accept that it might be useful on shutdown, and could see it being beneficial on demand (maybe via rpc)
  83 2016-10-18T03:28:28  <morcos> but writing it every 10 mins just seems like a way to clog up your node doing useless crap
  84 2016-10-18T03:28:30  <gmaxwell> the 10 minute thing is something sipa added that wasn't in my requirements document. :P
  85 2016-10-18T03:29:05  <morcos> and in particular if somehow some bad tx in your mempool crashed your block creation code, maybe you don't want to reload with that mempool (but i guess you could do that manually)
  86 2016-10-18T03:29:45  <gmaxwell> I don't think we disagree.  (The goals in saving it: prevent being utterly cold on newly recieved blocks after you do a simple restart for config changes, to not lose your transaction prioritization, to not reject dependant transactions as orphans which you never recieve, to not needlessly end up mining small blocks for an hour after a boring restart...)
  87 2016-10-18T03:30:25  <gmaxwell> well if you're crashing you can delete the file. I'm not particularly worried about that, and the import path goes through the normal accept logic, it's not just crammed back into the mempool. (meaning a network peer could give you the same garbage)
  88 2016-10-18T03:31:38  <morcos> ok, i guess just making your node to extensive disk access every 10 minutes gives me the heebie jeebies
  89 2016-10-18T03:31:47  <gmaxwell> the lack of the saving/loading also means that all of us spend far too much time messing around with nodes in unrepresentative states, throwing off benchmarking, and risking that we don't see issues that only show up with the mempool nice and fat.
  90 2016-10-18T03:32:01  <morcos> instead of roughly writing 1MB every 10 mins, now you'll write 300
  91 2016-10-18T03:32:13  <gmaxwell> Yea, well, I'm not a fan of the 10 minute thing. I'd be happier if it was on shutdown and had a rpc to trigger, and if you want 10 minutes you can call the rpc yourself. :)
  92 2016-10-18T03:32:34  <morcos> i would be way happier with that
  93 2016-10-18T03:33:06  <gmaxwell> I think the rational for the 10 minute saves is to make it useful across crashes. Which has merit, but-- I'd rather just not crash. :)
  94 2016-10-18T03:33:31  <morcos> looking back at the PR discussion, i think sipa wanted prioritization info to be saved in the event of a crash
  95 2016-10-18T03:33:39  <morcos> but do people actually have nodes that crash?
  96 2016-10-18T03:33:42  <morcos> is that a thing?
  97 2016-10-18T03:33:57  <gmaxwell> horrifyingly, yes. But we don't have to embrace all of reality.

 110 2016-10-18T03:49:49  <luke-jr> I wonder if the hardware-induced crashes are such that we can detect them with a repeat easily
 111 2016-10-18T03:50:03  <luke-jr> (and then complain to the user that their hardware is certainly faulty)
 112 2016-10-18T03:50:17  <gmaxwell> "Non-determinstic hardware detected (this is bad)"
 113 2016-10-18T03:51:07  <luke-jr> "It's not that we don't like you overclocking, but rather that your overclocking has actually given us the wrong answer to math, which is kinda important to Bitcoin working right."

 118 2016-10-18T03:58:14  <TD-Linux> also the existing PR fsync()'s on every write, which is probably fine on exit but is not great for interactive performance, especially on linux
 119 2016-10-18T03:58:41  * luke-jr wonders how much performance gain we'd get by using the file-specific fsync calls
 120 2016-10-18T04:00:08  <TD-Linux> luke-jr, it already does, the problem is on Linux other accesses will be queued behind the gigantic write
 121 2016-10-18T04:00:31  <tulip> TD-Linux: manual telemetry can be a thing, sort of. rather than asking users to dig around for things in a debug.log you can make a cohesive blob and a message that says "report this to your handler if you want to".
 122 2016-10-18T04:10:15  <luke-jr> TD-Linux: hmm, some filesystems on Linux seem to have another ioctl for fsyncing a specific file; I guess the normal one does it to a specific fd as well.. not sure what the difference is
 123 2016-10-18T04:14:56  <TD-Linux> luke-jr, not sure, but the buffering issue is lower level: https://lwn.net/Articles/682582/

 164 2016-10-18T06:11:10  <btcdrak> still doesnt invalidate what I am saying. 300MB flush every 10 mins isnt a big deal. this is 2016

 179 2016-10-18T06:54:04  <btcdrak> that's only a 5200rpm thing too
 180 2016-10-18T06:54:26  <luke-jr> I did it on btrfs since I expect poorer performance from it
 181 2016-10-18T06:54:34  <luke-jr> but a relatively new drive, so
 182 2016-10-18T06:56:29  <TD-Linux> btcdrak, that's implausibly high for a spinning disk. you're not syncing afterwards
 183 2016-10-18T06:58:38  * luke-jr also forgot to sync :x
 184 2016-10-18T06:59:00  <luke-jr> real    0m6.677s
 185 2016-10-18T06:59:15  <luke-jr> so 47 MB/s
 186 2016-10-18T07:00:05  <luke-jr> (sync before starting it too)
 187 2016-10-18T07:06:19  <TD-Linux> right, I'm not so much concerned about speed as the impact on other i/o while that is happening. I think it's probably acceptable, but it's possible to do better
 188 2016-10-18T07:07:00  <btcdrak> why does actual sync matter? Why are we concerned about the background processes of the host computer?
 189 2016-10-18T07:12:11  <paveljanik> btcdrak, it is 300+MB in the default config. And in the typical use case (nonstop, no failure run), we write, write, write and do not use the written data at all.
 190 2016-10-18T07:12:27  <paveljanik> slowly killing the disks...

 198 2016-10-18T07:21:09  <gmaxwell> besides, writing the mempool is just wasting SSD write endurance. Bitcoin Core doesn't crash. If you're in some weird enviroment where you care, you can call the rpc yourself.
 199 2016-10-18T07:21:13  <luke-jr> are we locking the mempool while it writes too? :x

 212 2016-10-18T07:46:04  <gmaxwell> Yes, assuming people find it acceptable for master.

 214 2016-10-18T07:46:40  <gmaxwell> at least my expirence and tulip's is that absent it, 0.13.1rc1 is prone to not getting any witness peers.

 259 2016-10-18T09:50:00  <wumpus> if you are really masochistic you can try to build bitcoin core with MSVC, most of the hassle is getting eventhing into the build system + setting config.h parameters manually
 260 2016-10-18T09:50:02  <jl2012> it seems windows and MAC are the same

 264 2016-10-18T09:50:39  <tulip> on my unpatched IPv4-only node I'm seeing 2 NODE_WITNESS, but I think that's a function of being in a busy ASN and having a low number of non-junk peers to begin with.

 300 2016-10-18T10:23:42  <luke-jr> Victorsueca: it might be possible in MSYS, but don't expect anything to just work
 301 2016-10-18T10:24:22  <sipa> Victorsueca: unless you're experienced with developing software using a mingw/msys build environment already, i expect that will take days of work to figure things out

 327 2016-10-18T11:18:01  <Victorsueca> wumpus: testing required? sure, I'll try it
 328 2016-10-18T11:18:12  <wumpus> it *looks* easy
 329 2016-10-18T11:20:38  <sipa> seriously, who would have believed you if 10 years ago someone told you that a future version of windows would ship with a built-in ubuntu environment...
 330 2016-10-18T11:21:08  <sipa> it still boggles my mind how much changed
 331 2016-10-18T11:21:13  <wumpus> yes. it's extremely surprising to me, even now. I intend to try it out but haven't found the time yet
 332 2016-10-18T11:21:23  <wumpus> indeed
 333 2016-10-18T11:22:42  <wumpus> the list of top OS-es includes a Linux and a BSD derivative, and windows is not doing that well
 334 2016-10-18T11:24:19  <wumpus> no one would have believed that in the 90's, heck not even any science fiction precited it :)

 346 2016-10-18T12:10:12  <michagogo> AIUI it's more like a built-in, disabled-by-default, hook that can then proceed to download an Ubuntu environment
 347 2016-10-18T12:11:36  <michagogo> i.e. you first need the computer in dev mode, then you go to the "enable/disable optional features" panel - same place you can enable things like built in telnet client, and all kinds of other niche stuff
 348 2016-10-18T12:12:06  <michagogo> Then that installs the "bash" stub that kicks off the install proces
 349 2016-10-18T12:12:52  <michagogo> wumpus: and yeah, from what I've read it seems there shouldn't really be any reason for it not to work
 350 2016-10-18T12:13:11  <michagogo> I mean, it's a full Ubuntu environment, running actual Linux binaries
 351 2016-10-18T12:13:29  <michagogo> And the software build process doesn't exactly involve any exotic syscalls...
 352 2016-10-18T12:13:46  <luke-jr> somehow I doubt it supports LXC or KVM
 353 2016-10-18T12:13:56  <luke-jr> so probably can't do gitian at least
 354 2016-10-18T12:14:03  <michagogo> (Things like lxc, mknods, chroots, etc reportedly don't work)
 355 2016-10-18T12:14:07  <wumpus> luke-jr: that's not what is described there, though
 356 2016-10-18T12:14:08  <michagogo> luke-jr: right
 357 2016-10-18T12:14:16  <sipa> just depends build would be nice
 358 2016-10-18T12:14:27  <michagogo> sipa: yeah, I'm pretty sure that should work
 359 2016-10-18T12:14:27  <wumpus> but I'd assume the same - user namespaces support is quite esoteric
 360 2016-10-18T12:14:48  <michagogo> I'll see if my mom will let me put WSL on her computer
 361 2016-10-18T12:16:02  <luke-jr> michagogo: does chattr +i work? :P

 367 2016-10-18T12:17:20  <wumpus> eh to windows ones
 368 2016-10-18T12:19:09  <jonasschnelli> does the WIN10 WSL comes with a window manager in a windows-window? Probably no...
 369 2016-10-18T12:19:50  <wumpus> heh seems in the same year OpenBSD removed support for linux executables, windows added it
 370 2016-10-18T12:20:02  <wumpus> jonasschnelli: no, it doesn't come with GUI support
 371 2016-10-18T12:20:23  <wumpus> libwin32gui on ubuntu would be kind of interesting, though heretical :)
 372 2016-10-18T12:22:12  <wumpus> though I doubt there's anything preventing your from running a windows X server on windows and connect to that
 373 2016-10-18T12:22:25  <wumpus> circuitous, but meh

 405 2016-10-18T12:48:21  <achow101> michagogo: I've been able to compile both linux and windows binaries on WSL
 406 2016-10-18T12:48:29  <achow101> but I haven't gotten gitian to work yet
 407 2016-10-18T12:49:49  * wumpus would be really surprised if you get gitian to work as-is. You could try to launch the descriptors without VM (as michagogo said), and build like that, after all it's the same OS as unsed in the internal VM in gitian. But you may have some work getting the same output as others
 408 2016-10-18T12:50:29  <michagogo> wumpus: not what I meant
 409 2016-10-18T12:50:40  <michagogo> I meant, run gitian itself in WSL
 410 2016-10-18T12:50:44  <michagogo> And use VBox
 411 2016-10-18T12:50:55  <wumpus> you can't run gitian in WSL, there's no virtualization support
 412 2016-10-18T12:51:15  * luke-jr wonders if WSL can call Windows-build qemu
 413 2016-10-18T12:51:15  <michagogo> No, but maybe it can control native vbox
 414 2016-10-18T12:51:26  <michagogo> Or ^^
 415 2016-10-18T12:51:44  <wumpus> luke-jr: indeed, if you can launch native exes
 416 2016-10-18T12:52:07  <wumpus> windows qemu is strange though
 417 2016-10-18T12:52:09  <luke-jr> at least in the kqemu days, IIRC there was virt support for qemu on windows
 418 2016-10-18T12:52:34  <wumpus> I tried that once, and was unable to get accelerated virtualization to work
 419 2016-10-18T12:53:12  <luke-jr> kqemu is pretty old stuff :p
 420 2016-10-18T12:53:17  <luke-jr> pre-VT-x
 421 2016-10-18T12:53:28  <michagogo> Hrm
 422 2016-10-18T12:53:30  <wumpus> it may need some special driver that needs to be installed as admin, dunno
 423 2016-10-18T12:53:38  <michagogo> Nope, it looks like it's a full environment
 424 2016-10-18T12:53:41  <michagogo> Not like cygwin
 425 2016-10-18T12:54:35  <michagogo> bash: /mnt/c/Windows/System32/gpupdate.exe: cannot execute binary file: Exec format error
 426 2016-10-18T12:55:22  <michagogo> Looks like within WSL it's Linux-only
 427 2016-10-18T12:55:38  <michagogo> I wonder if there's a way to workaround it
 428 2016-10-18T12:56:34  <achow101> wine in wsl ;D
 429 2016-10-18T12:57:18  <michagogo> Hmmmmm
 430 2016-10-18T12:57:40  <wumpus> hahha OSS people aren't happy until they can do a full emualtion roundtrip
 431 2016-10-18T12:59:36  <Victorsueca> would it be possible to do WSL on Wine on WSL.... :P
 432 2016-10-18T12:59:50  <Victorsueca> Inception!
 433 2016-10-18T13:00:16  <wumpus> :')
 434 2016-10-18T13:01:43  <wumpus> shouldn't be to difficult to support the WSL syscalls in wine
 435 2016-10-18T13:03:00  <michagogo> Wine doesn't want to install
 436 2016-10-18T13:03:16  <michagogo> Looks like a bunch of i386 packages not coming in
 437 2016-10-18T13:03:20  <wumpus> I'd expected so
 438 2016-10-18T13:03:28  <luke-jr> wumpus: lol
 439 2016-10-18T13:03:39  <michagogo> I wish apt were better at showing actual cause
 440 2016-10-18T13:04:12  <michagogo> It says winehq-devel : Depends: wine-devel
 441 2016-10-18T13:04:15  <timothy> hi, do you think can be good to add support for rpc to tor?
 442 2016-10-18T13:04:22  <timothy> actually only 8333 is supported
 443 2016-10-18T13:04:23  <wumpus> not just a matter of sudo dpkg --add-architecture i386  ?
 444 2016-10-18T13:04:25  <michagogo> (Unmet dependency)
 445 2016-10-18T13:04:29  <michagogo> wumpus: I did that first
 446 2016-10-18T13:04:47  <timothy> (integrated, I mean. ofc you can use the "standard" tor feature to add rpc port)
 447 2016-10-18T13:04:49  <michagogo> And it says "you have held broken packages", which is misleading
 448 2016-10-18T13:05:09  <michagogo> Anyway, wine-devel then depends on wine-devel-i386
 449 2016-10-18T13:05:12  <wumpus> timothy: if you really want to expose your RPC port on a Tor hidden service that's possible
 450 2016-10-18T13:05:37  <michagogo> And that, in turn, depends on a whole lot of :i386 packages
 451 2016-10-18T13:05:39  <wumpus> timothy: wouldn't advice doing it by default though, a lot of scope to mess up
 452 2016-10-18T13:05:46  <timothy> wumpus: actually I use it only for opentimestamps
 453 2016-10-18T13:05:48  <michagogo> Some say "but it is not going to be installed"
 454 2016-10-18T13:05:56  <timothy> I don't have any wallets here
 455 2016-10-18T13:06:02  <michagogo> But then some say "but it is not installable"
 456 2016-10-18T13:06:20  <wumpus> at the least don't give the onion address to anyone (or link it anywhere public) otherwise it will be picked up and probed by projects like onionscan
 457 2016-10-18T13:06:32  <michagogo> Maybe I could poke at it and figure out what's going on, but a. I don't really care enough
 458 2016-10-18T13:06:43  <michagogo> And b. I doubt I'd be able to figure it out anyway :P
 459 2016-10-18T13:06:44  <timothy> wumpus: ofc it's only for private use and on another port (not 8332)
 460 2016-10-18T13:07:30  <wumpus> if you have no wallet on the node it's certainly safer, though still: RPC is not a public interface, it's not as hardened against DoS and other attacks as the P2P
 461 2016-10-18T13:07:45  <michagogo> Would be nice if depends could multitask
 462 2016-10-18T13:08:00  <timothy> wumpus: so do you suggest me to add another layer like stunnel with client cert?
 463 2016-10-18T13:08:09  <wumpus> timothy: for private use it's fine
 464 2016-10-18T13:08:31  <luke-jr> michagogo: it can't?
 465 2016-10-18T13:08:56  <wumpus> timothy: no need for that, tor has hs security built-in, look into "hidden service authentication"
 466 2016-10-18T13:09:40  <wumpus> with HidServAuth something you can restrict who can connect to your hidden service with certain keys
 467 2016-10-18T13:09:41  <michagogo> luke-jr: I mean, maybe -jx works within a build
 468 2016-10-18T13:09:54  <michagogo> But I mean, for example, download and build different packages in parallel
 469 2016-10-18T13:10:09  <timothy> wumpus: not bad, thank you
 470 2016-10-18T13:10:11  <luke-jr> michagogo: make -jN in depends/?
 471 2016-10-18T13:10:17  <michagogo> luke-jr: I did that
 472 2016-10-18T13:10:29  <michagogo> Maybe each individual compilation job is multitasking
 473 2016-10-18T13:10:36  <michagogo> But it's doing one package at a time

 503 2016-10-18T13:19:40  <michagogo> (Unless you think there's a chance it might not work where everything else might?)
 504 2016-10-18T13:20:21  <wumpus> there's some small chance of that because of the cross-build X stuff, and all the other deps qt drags in, but it'll probably work

 563 2016-10-18T13:49:32  *** cryptapus has quit IRC
 564 2016-10-18T13:49:39  <michagogo> molz: which dependencies?
 565 2016-10-18T13:49:55  <michagogo> The ones for Bitcoin are downloaded and built by those commands
 566 2016-10-18T13:50:03  <michagogo> (The cd depends;make HOST...)
 567 2016-10-18T13:50:25  <molz> oh..
 568 2016-10-18T13:50:30  <michagogo> The apt-get command installs everything that the build process needs
 569 2016-10-18T13:51:17  <michagogo> Like I said, if you install WSL completely fresh from scratch (or for that matter, "real" Ubuntu 14.04...), those commands are everything you need to produce Bitcoin-qt.exe
 570 2016-10-18T13:51:23  <michagogo> (And all the others)
 571 2016-10-18T13:52:44  <michagogo> wumpus: what is test_bitcoin-qt.exe supposed to do?
 572 2016-10-18T13:52:57  <michagogo> It seems to just return to the command line immediately
 573 2016-10-18T13:52:59  <michagogo> No output
 574 2016-10-18T13:53:01  <sipa> run the bitcoin-qt unit test
 575 2016-10-18T13:53:46  <michagogo> sipa: is it supposed to output anything, like test_bitcoin.exe does?
 576 2016-10-18T13:53:48  <wumpus> it should print something about Start Testing Finished Testing, normally
 577 2016-10-18T13:53:54  <sipa> unsure
 578 2016-10-18T13:54:04  <michagogo> Doesn't look like it?
 579 2016-10-18T13:54:06  <wumpus> but I've never tried it in windows
 580 2016-10-18T13:54:15  <molz> michagogo, ok i'm not on win10, can the irccloud guide be used on Ubuntu 14.4 VM ?
 581 2016-10-18T13:54:15  <michagogo> I just get the prompt back
 582 2016-10-18T13:54:28  <molz> i'm installing Ubuntu 14.4 on the VM right now
 583 2016-10-18T13:54:28  <wumpus> maybe it's accidentally compiled as a UI subsystem instead of console subsystem executable?
 584 2016-10-18T13:54:47  <michagogo> molz: yeah, those commands should work on a fresh install of 14.04
 585 2016-10-18T13:54:55  <sipa> wumpus: maybe not accidentally... a qt app may need to be gui
 586 2016-10-18T13:54:58  <molz> ok, thanks, going to try it now
 587 2016-10-18T13:55:04  <MarcoFalke> Anything holding back https://github.com/bitcoin/bitcoin/pull/8928
 588 2016-10-18T13:55:22  <wumpus> sipa: it doesn't need to be, console will just open a console at startup, it can still use the UI APIs
 589 2016-10-18T13:55:33  <sipa> ah
 590 2016-10-18T13:55:46  <wumpus> (though none of the Qt unit tests does anything with UI)
 591 2016-10-18T13:55:55  <michagogo> We don't seem to ship test_bitcoin-qt.exe
 592 2016-10-18T13:56:04  <wumpus> that's on purpose - it's silly right now
 593 2016-10-18T13:56:20  <michagogo> The win64 zip for 0.13.0 from Bitcoin.org has test_bitcoin.exe but not -qt
 594 2016-10-18T13:56:20  <wumpus> it's a huge executable when statically linking, pulling in much of qt, for no good reason
 595 2016-10-18T13:56:42  <michagogo> So I'm guessing it's not something wrong with this build setup
 596 2016-10-18T13:56:49  <wumpus> yes, test_bitcoin.exe is suposed to be in there
 597 2016-10-18T13:56:54  <wumpus> I'm guessing the same
 598 2016-10-18T13:57:12  <michagogo> If I run Bitcoin-Qt.exe with a -datadir argument, does it leave traces of itself anywhere but that directory?
 599 2016-10-18T13:57:34  <sipa> it shouldn't
 600 2016-10-18T13:57:37  <wumpus> yes - in the registry
 601 2016-10-18T13:57:46  <wumpus> bitcoind.exe shouldn't, though
 602 2016-10-18T13:58:03  <michagogo> Anything outside a simple key named for the app?
 603 2016-10-18T13:58:24  <wumpus> no, it's one 'directory' named bitcoin-qt or such
 604 2016-10-18T13:58:27  <wumpus> with qt settings
 605 2016-10-18T13:59:04  <michagogo> Okay, that's tolerable

 637 2016-10-18T14:11:12  <jlopp> I asked these questions in wizards yesterday; crossposting for more visibility:
 638 2016-10-18T14:11:24  <jlopp> I'm trying to better understand the purpose and future use of checkpoints in Bitcoin. My understanding is that the checkpoints are in place in order to prevent attackers from spamming nodes with low PoW block headers at low chain heights. And that a side effect of checkpoints is a performance speedup in initial block download due to skipping signature verification.
 639 2016-10-18T14:11:37  <jlopp> Though I thought that since libsecp256k1 drastically increases signature validation performance, the speedup is negligible now.
 640 2016-10-18T14:11:47  <jlopp> back in 2013, gmaxwell said "When headers first syncing is merged, just by adding a "must be this tall" minimum sum difficulty check we'll be able to remove checkpoints for all DOS purposes, and we'll also be able to remove them for syncing acceleration (using random sampling for ECDSA in the deeply buried chain)."
 641 2016-10-18T14:11:56  <jlopp> seems like sipa also thought headers-first sync would enable removal of checkpoints... https://bitcoin.stackexchange.com/questions/7826/what-alternatives-are-there-to-hardcoding-checkpoints-into-the-bitcoin-client
 642 2016-10-18T14:11:58  <wumpus> jlopp: helps to read https://github.com/bitcoin/bitcoin/issues/7591
 643 2016-10-18T14:12:31  <wumpus> checkpoints really need to go, and are not part of the security model, however they are still used for three of so tasks which haven't been replaced with other implementations
 644 2016-10-18T14:13:45  <wumpus> there's always the -checkpoints=0 option if you can't wait for them to be removed
 645 2016-10-18T14:14:00  <jlopp> Am I correct in stating that it wouldn't be possible to feed any alternative chain of blocks to a full node if that alternative chain's starting point was prior to block 295000? It's also not clear to me why there are 13 checkpoints rather than just the last one at 295000

 653 2016-10-18T14:18:14  *** Giszmo has joined #bitcoin-core-dev
 654 2016-10-18T14:18:53  <sipa> BlueMatt: maybe someone at dci?
 655 2016-10-18T14:19:29  <BlueMatt> that was suggested, I can reach out to neha and see if there are any students interested in running one
 656 2016-10-18T14:19:50  <BlueMatt> I'm happy to run one, but want to use real servers which implies no longer wanting to pay for it out-of-pocket
 657 2016-10-18T14:20:01  <BlueMatt> (and only if there is an additional one run by someone else)
 658 2016-10-18T14:20:45  <neha> We can probably run one.  What are the bw/hard drive/mem/etc requirements?
 659 2016-10-18T14:21:50  <BlueMatt> neha: i mean a network, not node
 660 2016-10-18T14:22:17  <BlueMatt> which means dedicated servers roughly in similar locations as those on the map at http://bitcoinrelaynetwork.org/
 661 2016-10-18T14:22:25  <nsh> cc musalbas
 662 2016-10-18T14:22:35  <neha> a network starts with one node?  :) ok let me know what the requirements are and we can talk about it.  there probably will be student interest
 663 2016-10-18T14:22:50  <BlueMatt> probably 100-200/mo per server (say, 5 of them + some auxillary stuff) if you're lazy about finding deals, maybe as low as 50
 664 2016-10-18T14:23:13  <sipa> units?
 665 2016-10-18T14:23:16  <sipa> what is a mo
 666 2016-10-18T14:23:22  <wumpus> month
 667 2016-10-18T14:23:36  <BlueMatt> usd/cad/eur/gbp/etc
 668 2016-10-18T14:23:39  <BlueMatt> any of them are valid
 669 2016-10-18T14:24:13  <sipa> ah
 670 2016-10-18T14:24:15  <neha> could we get multiple universities to run nodes as part of one network?
 671 2016-10-18T14:24:53  <BlueMatt> neha: because of the weird trust-all-nodes-in-the-network requirement if you want to run with cut-through on, thats....awkward
 672 2016-10-18T14:25:19  <BlueMatt> neha: i mean could turn off the cut-through and do it
 673 2016-10-18T14:25:37  <BlueMatt> if its on a fast-single-threading server with good peak bw that might be ok
 674 2016-10-18T14:26:02  <sipa> the only issue is that the nodes within the network could dos each other, right?
 675 2016-10-18T14:26:28  <BlueMatt> if you do trusted mode any node can break propagation for a block to the entire network
 676 2016-10-18T14:26:31  <wumpus> so it's mainly miners using this right: aren't any miners/mining pools interested in setting up a network like this?
 677 2016-10-18T14:26:56  <neha> do the nodes need to be geo-distributed?
 678 2016-10-18T14:27:04  <neha> (i need to read more about fibre)
 679 2016-10-18T14:27:16  <BlueMatt> wumpus: i have no idea why miners seemingly only ever provide lip-service to things like this :/
 680 2016-10-18T14:27:30  <wumpus> BlueMatt: I was afraid you were going to say that
 681 2016-10-18T14:27:48  <sipa> wumpus: arguably, it's more in the interest of the network at large that such a network exists, as opposed to miners running their own private setups that are harder to enter as an outsider
 682 2016-10-18T14:27:49  <BlueMatt> wumpus: well, i do know, for many of them it doesnt matter because they just do spy-mining

 685 2016-10-18T14:28:14  <sipa> BlueMatt: neutrinos.
 686 2016-10-18T14:28:26  <BlueMatt> oooo bitcoin-over-neutrino
 687 2016-10-18T14:28:37  <BlueMatt> might want to get ip-over-neutrino to work first, though
 688 2016-10-18T14:28:39  <neha> this might be a good thing for a network of universities to do.
 689 2016-10-18T14:28:52  <neha> don't need to worry too much about schools (intentionally) dos'ing each other
 690 2016-10-18T14:28:54  <BlueMatt> neha: indeed, universities tend to have good low-latency bw between each other, too
 691 2016-10-18T14:29:04  <Victorsueca> ip-over-dark-matter is better
 692 2016-10-18T14:29:08  <BlueMatt> neha: well, I think it'd still need to run in non-trusted mode
 693 2016-10-18T14:29:34  <BlueMatt> neha: you do need to worry about someone randomly fucking with one node to screw over block prop. for a given pool at unis
 694 2016-10-18T14:29:47  <BlueMatt> security at uni-hosting places tends to be.......
 695 2016-10-18T14:30:17  <Victorsueca> deficient? is that the word you're searching?
 696 2016-10-18T14:30:29  <wumpus> Victorsueca: ip-over-microwormholes
 697 2016-10-18T14:30:29  <sipa> BlueMatt: can you have two tiers? different orgs running their own nodes, internally cut-through, but not cut-through across orgs

 699 2016-10-18T14:30:36  <BlueMatt> sipa: yes
 700 2016-10-18T14:30:41  <Victorsueca> wumpus: lol
 701 2016-10-18T14:30:51  <sipa> BlueMatt: and then have maybe one org colocate one of their nodes inside or nearby another org's node
 702 2016-10-18T14:31:08  <Victorsueca> wumpus: with that you could recieve data even before it's sent
 703 2016-10-18T14:31:21  <BlueMatt> sipa: not sure how required the second part is...you just end up having a reconstruction-latency on the first hop into an org always
 704 2016-10-18T14:31:30  <sipa> right
 705 2016-10-18T14:31:37  <BlueMatt> sipa: fibre is rather packet-loss-insensitive :)
 706 2016-10-18T14:34:39  <sipa> BlueMatt: well, in any case, it's probably easier to get people interested in this technology and infrastructure if you first ask to run just a node in an exisitng network
 707 2016-10-18T14:35:17  <BlueMatt> sipa: true
 708 2016-10-18T14:35:22  <neha> agree
 709 2016-10-18T14:36:41  <neha> it would be helpful to think about how interested parties at a school could just stand up a node as part of an existing network
 710 2016-10-18T14:37:02  <neha> we have almost "free" access to compute resources, but only locally.
 711 2016-10-18T14:37:12  <BlueMatt> hmm, for that to be useful I think I'd have to run an actual network and let people peer into it
 712 2016-10-18T14:37:56  <BlueMatt> which I'd gladly do, but dont want to funt it myself anymore if I'm gonna stand up a real network
 713 2016-10-18T14:38:08  <neha> bitcoin foundation?
 714 2016-10-18T14:38:17  <neha> or us i suppose depending on costs
 715 2016-10-18T14:38:18  <BlueMatt> they dont have any $$$ left
 716 2016-10-18T14:38:40  <neha> wouldnt your "network" be very small, with most of the resources provided being from people peering?
 717 2016-10-18T14:38:59  <michagogo> Victorsueca: is there something wrong with that last gist?
 718 2016-10-18T14:39:46  <michagogo> And in terms of all the libraries, if you mean the ones that go into Bitcoin Core (OpenSSL, Qt, boost, etc.), the whole beauty of the depends system is that you don't need to know about that
 719 2016-10-18T14:39:58  <sipa> BlueMatt: we'll need a SF to commit to error correction packets :)
 720 2016-10-18T14:40:20  <BlueMatt> sipa: yes, probalem is putting it in the coinbase is expensive, so we need a HF to commit to ECC packets :p
 721 2016-10-18T14:40:22  <Victorsueca> michagogo: no idea, the console seemed to error out, but after spamming the make command a few times it started working
 722 2016-10-18T14:40:30  <michagogo> Victorsueca: what did the consoel look like?

 724 2016-10-18T14:41:07  <Victorsueca> michagogo: lots of error being spammed out, stuff outside of the directory, automake is not available....
 725 2016-10-18T14:41:08  <sipa> BlueMatt: which you require to be small
 726 2016-10-18T14:41:42  <BlueMatt> sipa: just traversing down the merkle tree is non-trivial in byte count when you only have <1500 bytes to play with

 734 2016-10-18T14:58:20  <BlueMatt> one option for a fibre network: be super lazy and spin up servers primarily on softlayer - ~$1500/mo to softlayer and probably another 200 to other providers to bridge the gaps

 741 2016-10-18T15:10:55  <michagogo> Interesting
 742 2016-10-18T15:11:17  <michagogo> Looks like b2 (boost build tool) is passed -j2 regardless of the depends make -j argument
 743 2016-10-18T15:11:22  <michagogo> (assuming it means the same thing there)
 744 2016-10-18T15:12:25  <michagogo> Yep, hard-coded:   ./b2 -d2 -j2 -d1 --prefix=$($(package)_staging_prefix_dir) $($(package)_config_opts) stage
 745 2016-10-18T15:12:41  <michagogo> cfields_: any particular reason for that?
 746 2016-10-18T15:12:59  <wumpus> michagogo: does -j do the same for b2 as for make?
 747 2016-10-18T15:13:09  <michagogo> Yeom just checked that
 748 2016-10-18T15:13:12  <michagogo> Yep,*
 749 2016-10-18T15:13:18  <michagogo> -j N
 750 2016-10-18T15:13:18  <michagogo> Run up to N commands in parallel.
 751 2016-10-18T15:13:27  <michagogo> from http://www.boost.org/build/doc/html/bbv2/overview/invocation.html
 752 2016-10-18T15:13:36  <cfields_> michagogo: hmm, no reason. Just got left in after testing i guess
 753 2016-10-18T15:13:38  <wumpus> ok. Probably accidental then
 754 2016-10-18T15:13:50  <cfields_> I'm pretty sure you can grab the parallel value from make somehow
 755 2016-10-18T15:14:15  <Victorsueca> I use make with -j4
 756 2016-10-18T15:14:22  <michagogo> Hm, OpenSSL forces -j1
 757 2016-10-18T15:14:32  <wumpus> yes, openssl is broken otherwise
 758 2016-10-18T15:14:39  <wumpus> (the build, not the library)
 759 2016-10-18T15:14:47  <cfields_> yes, that one's on purpose
 760 2016-10-18T15:14:54  <michagogo> ah
 761 2016-10-18T15:15:50  <wumpus> don't know if that's still the case with more recent openssl, but it used to be that there was a race between some parts of the builds (esp. when assembly enabled) preventing paralellel builds
 762 2016-10-18T15:16:05  <Victorsueca> damn, can't reash confdefs.h No such file or directory

 766 2016-10-18T15:16:30  <wumpus> Victorsueca: I'm baffled that michagogo had such an easy time building while you seem to stumble into every possible issue :)

 862 2016-10-18T16:35:50  <sipa> zfs internally has a 256-bit hash associated with every "pointer" to a disk location, with a hash off the data record pointed to

 932 2016-10-18T17:38:49  <wumpus> also it's very possible that people download the 32-bit version by accident even though they're on 64-bit
 933 2016-10-18T17:39:13  <Victorsueca> doesn't the page detect your OS and arch?

 936 2016-10-18T17:39:42  <Victorsueca> the browser could be x32 by accident
 937 2016-10-18T17:39:52  <gmaxwell> that was an issue for fedora for a long time, they recommended 32bit as the main download because it was the most downloaded one... meanwhile the overwhelming majority of users were on 64bit hardware.
 938 2016-10-18T17:40:26  <TD-Linux> Victorsueca, or on purpose. most browser plugins are 32 bit only

 958 2016-10-18T17:44:59  <wumpus> gmaxwell: I just don't think it's used anymore in practice. What was the last 32-bit only CPU?
 959 2016-10-18T17:45:07  <TD-Linux> wumpus, lots of antivirus installs browser plugins (one of the reasons to remove it actually), also realplayer-tier stuff like United's inflight video
 960 2016-10-18T17:45:11  <wumpus> (I mean commonly used intel one, not ARM)
 961 2016-10-18T17:45:18  <Victorsueca> sipa: I think that's called wine, but i don't think it comes pre-installed, you have to apt-get it

 963 2016-10-18T17:46:23  <wumpus> "many malware is still 32-bit" hehe
 964 2016-10-18T17:47:22  <TD-Linux> wumpus, indeed, but then you tempt the antivirus vendors to binary patch your executable instead.

 967 2016-10-18T17:49:26  <wumpus> sipa: that doesn't mean anyone is using it though
 968 2016-10-18T17:50:49  <wumpus> I don't really feel like arguing about this though, if everyone here feels that supporting windows 32 bit is still worth it, let's keep doing that, please also help with support if issues come up tho
 969 2016-10-18T17:50:52  <Lightsword> wumpus, doesn’t luke-jr use 32 bit userspace or something strange?
 970 2016-10-18T17:50:59  <wumpus> Lightsword: on linux, yes
 971 2016-10-18T17:51:00  <TD-Linux> likely because they wanted to migrate all windows 7 and 8 installs to 10, and doing an upgrade to a different arch is high risk
 972 2016-10-18T17:51:26  <sipa> wumpus: oh, i'm not arguing - i'm just as curious as you about actual usefulness of 32-bit windows
 973 2016-10-18T17:51:52  <wumpus> linux 32-bit is still used on VPSes with small memory (nano instances and such) so there's a reasonable user base
 974 2016-10-18T17:52:11  <Lightsword> my guess is it might not be all that uncommon for people to want a full node on some ancient systems they have lying around so 32 bit windows might be useful for that
 975 2016-10-18T17:52:25  <wumpus> but we deprecated 32-bit Mac ages ago, and windows really is in the same ballpark as that, an end-user OS
 976 2016-10-18T17:52:26  <Lightsword> as a dedicated box they stick in a closet or something
 977 2016-10-18T17:53:03  <Lightsword> wumpus, yeah but apple deprecated 32-bit mac right?

 991 2016-10-18T17:56:44  <wumpus> so are there any of those, using windows?
 992 2016-10-18T17:57:01  <wumpus> if you have low memory you probaly shouldn't be using that
 993 2016-10-18T17:57:13  <wumpus> same for small embedded hw
 994 2016-10-18T17:57:39  <gmaxwell> Victorsueca: using bitcoin ia32 should not be considerably more memory efficient.
 995 2016-10-18T17:58:31  <sipa> i think they are
 996 2016-10-18T17:58:47  <sipa> mempool, cpu cache, block index... they're all considerably smaller on 32-bit systems
 997 2016-10-18T17:59:09  <sipa> not a factor 2, but perhaps 20-30%
 998 2016-10-18T17:59:51  <Victorsueca> also you can't use bitcoin x64 on a ia32 os tho even if your system supports x64 you may want to use ia32 OS and that would actually save a lot of memory
 999 2016-10-18T18:00:50  <wumpus> so, who is volunteering to do 32-bit windows testing for bitcoin core?
1000 2016-10-18T18:01:59  <gmaxwell> I can do that.
1001 2016-10-18T18:02:01  <Victorsueca> I could do it, if I ever get to compile the x64 one and get it to work i'll try with the ia32
1002 2016-10-18T18:02:06  <wumpus> great
1003 2016-10-18T18:02:53  <wumpus> you should test on a 32-bit OS then, not a 64-bit one
1004 2016-10-18T18:03:21  <Victorsueca> ^ RIP ia32 lol
1005 2016-10-18T18:03:42  <Victorsueca> isn't it the same?
1006 2016-10-18T18:03:49  <wumpus> no, it's not the same
1007 2016-10-18T18:04:04  <Victorsueca> damn
1008 2016-10-18T18:04:12  <Victorsueca> gmaxwell: you're the only hope :D
1009 2016-10-18T18:08:11  <Victorsueca> well, now I think about it... if the main function of the ia32 will be saving memory why don't we just test it in a x64 OS and say there's no support for ia32 OS?
1010 2016-10-18T18:09:19  <sipa> Victorsueca: well gmaxwell points out that people may be running a 32-bit OS, not knowing their hardware supports x86_64
1011 2016-10-18T18:10:20  <achow101> I may be able to help test 32 bit windows, depends on what exactly needs to be done in order to test
1012 2016-10-18T18:10:35  <wumpus> achow101: run a node 24/7 on 32-bit windows at least
1013 2016-10-18T18:10:42  <wumpus> debug when things crash
1014 2016-10-18T18:12:41  <wumpus> maybe try running test_bitcoin and the qa tests on it once in a while. But that's fairly well handled by travis and wine, I think most important is actual usage testing and solving problems that come up
1015 2016-10-18T18:16:42  <achow101> ok. does it matter if it's in a vm?
1016 2016-10-18T18:17:55  <wumpus> no

1024 2016-10-18T18:29:11  <Victorsueca> trying to figure out why the heck does my system become unresponsive while compiling qt
1025 2016-10-18T18:29:27  <Victorsueca> i'm stuck there and can't continue building bitcoin
1026 2016-10-18T18:29:30  <wumpus> memory full?
1027 2016-10-18T18:29:42  <Victorsueca> 85%
1028 2016-10-18T18:29:45  <wumpus> it's c++ code, if you use too much parallelism it's easy tofill up memory
1029 2016-10-18T18:30:04  <Victorsueca> should I try -j1?
1030 2016-10-18T18:30:22  <wumpus> yes, you could try
1031 2016-10-18T18:34:32  <Victorsueca> I just didn't specify that option, how many threads does qt use by default when compiling?
1032 2016-10-18T18:35:00  <sipa> q
1033 2016-10-18T18:35:01  <sipa> 1
1034 2016-10-18T18:35:34  <Victorsueca> 1? and still out of memory? wtf?
1035 2016-10-18T18:35:43  <sipa> how much memory do you have?
1036 2016-10-18T18:35:48  <Victorsueca> 4GB
1037 2016-10-18T18:35:59  <sipa> how much is available for the linux env?
1038 2016-10-18T18:36:15  <sipa> you need something like 1.5 or 2 GB to compile bitcoin core, i think
1039 2016-10-18T18:36:16  <wumpus> well it could very well be another problem, my observation was just that it's usually a memory/swap issue if the system becomes unresponsive during compilation
1040 2016-10-18T18:36:59  <wumpus> I'm sure there's some way to debug that
1041 2016-10-18T18:37:10  <Victorsueca> is WSL enviroment resource limited?
1042 2016-10-18T18:38:04  <Victorsueca> or it just can use everything windows has available?
1043 2016-10-18T18:38:20  <sipa> you tell us
1044 2016-10-18T18:38:30  <wumpus> yes this is probably not the right place to ask that
1045 2016-10-18T18:38:43  <Victorsueca> hmmm ok, i'll search on google

1049 2016-10-18T18:40:29  <Victorsueca> ^ +1, google searches seems to agree
1050 2016-10-18T18:41:25  <Victorsueca> so basically I have 4GB - System memory usage
1051 2016-10-18T18:42:07  <MarcoFalke> it is mostly main and init that consume most ram
1052 2016-10-18T18:42:24  <Victorsueca> will try j1 and see if it makes any difference

1084 2016-10-18T18:55:28  <wumpus> again, this is not a windows developer troubleshooting channel
1085 2016-10-18T18:55:35  <michagogo> 20:36:24 <TD-Linux> building bitcoin under the Ubuntu for Windows environment is supported now? <-- I don't know about Support, but it does seem to work!
1086 2016-10-18T18:55:41  <wumpus> maybe ##windows?
1087 2016-10-18T18:55:58  <michagogo> I mean, it's pretty much a full Ubuntu environment, so it's not so surprising
1088 2016-10-18T18:56:18  <Victorsueca> michagogo: it goes over 85% and a few seconds later it's unresponsive
1089 2016-10-18T18:56:45  <wumpus> I still bet it's swap trashing though
1090 2016-10-18T18:57:27  <michagogo> It's an Ubuntu user space and packages, and while more exotic syscalls aren't supported (so no LXC/KVM, no tail -f, etc.), a cross-compile toolchain runs just fine.
1091 2016-10-18T18:58:11  <Victorsueca> wumpus: how is that suposed to be fixed?
1092 2016-10-18T18:58:36  <michagogo> Victorsueca: most likely with more resources, unfortunately
1093 2016-10-18T18:58:52  <Victorsueca> damn
1094 2016-10-18T18:59:10  <wumpus> I wondered what makes tail -f so exotic, thought it was just a pollign loop, but apparently it uses inotify
1095 2016-10-18T19:00:02  <Victorsueca> i'll have to use my other computer then, didn't want to restart that one because it's hosting stuff
1096 2016-10-18T19:00:30  <sipa> wumpus: maybe tail --follow=name works better?
1097 2016-10-18T19:01:56  <wumpus> sipa: looks like that adds an inotify on both the file *and* the directory it's in :)

1161 2016-10-18T19:27:36  <achow101> but I only run one node
1162 2016-10-18T19:28:17  <jonasschnelli> achow101: A right. Confused! is you node..
1163 2016-10-18T19:28:26  <jonasschnelli> maybe try -debug=net and post the debug.log again
1164 2016-10-18T19:28:43  <achow101> I found the problem. If the option is in the bitcoin.conf, it won't work. I have to put it in the command line. Any idea why?
1165 2016-10-18T19:29:10  <wumpus> are you using connect= in your bitcoin.conf or -connect=?
1166 2016-10-18T19:29:21  <wumpus> the former will work, the second will not
1167 2016-10-18T19:29:22  <achow101> connect= in bitcoin.conf
1168 2016-10-18T19:29:23  <jonasschnelli> Should work in bitcoin.conf
1169 2016-10-18T19:29:44  <wumpus> is bitcoin.conf in the right place? does it get parsed at all?
1170 2016-10-18T19:29:48  <jonasschnelli> Doublecheck bitcoin.conf and -datadir (if passed in CLI)

1177 2016-10-18T19:31:40  <wumpus> one lousy way to find out if it's parsed is to put junk at the end, e.g. 'fasdjlfaljdfalfjk' then see if bitcoind gives an error at start :p

1192 2016-10-18T19:37:33  <michagogo> Hm, I really hope I find the time to rewrite build-windows.md
1193 2016-10-18T19:37:47  <michagogo> It seems to tell you to install all the unix dependencies
1194 2016-10-18T19:37:52  <michagogo> Which is just wrong
1195 2016-10-18T19:38:04  <michagogo> Or at least, it can be read that way
1196 2016-10-18T19:38:10  <wumpus> it doesn't hurt, but yeah it's overkill
1197 2016-10-18T19:38:29  <wumpus> only the high-level arch-independent build stuff would be necessary, autoconf automake etc
1198 2016-10-18T19:39:16  <michagogo> I mean, molz in #bitcoin was installing all the actual deps, it seems

1209 2016-10-18T19:42:27  <jonasschnelli> maybe we should open a issue for RN 0.14
1210 2016-10-18T19:42:40  <wumpus> there's an issue for that IIRC
1211 2016-10-18T19:42:46  <michagogo> wumpus: right
1212 2016-10-18T19:42:53  <wumpus> https://github.com/bitcoin/bitcoin/issues/8455
1213 2016-10-18T19:43:00  <michagogo> But the docs don't talk about running a deps build for unix
1214 2016-10-18T19:43:36  <wumpus> michagogo: only the docs in depends do :(
1215 2016-10-18T19:43:39  <michagogo> Build-unix.md walks you through doing a build with system-deps
1216 2016-10-18T19:43:49  <wumpus> michagogo: it's split all over the place, not always over sensible lines
1217 2016-10-18T19:43:53  <michagogo> And build-windows points you at build-unix...
1218 2016-10-18T19:44:07  <wumpus> and build-unix points you at build-openbsd :-)
1219 2016-10-18T19:44:10  <michagogo> When you really just need to install git make pkg-config libtool autoconf g++ g++-mingw-w64-x86-64
1220 2016-10-18T19:44:24  <michagogo> Well, it does for openbsd
1221 2016-10-18T19:44:38  <michagogo> Windows points to unix unconditionally
1222 2016-10-18T19:44:41  <wumpus> I know, that one makes sense
1223 2016-10-18T19:45:03  <michagogo> When all you need is git make pkg-config libtool autoconf g++ g++-mingw-w64-x86-64
1224 2016-10-18T19:45:16  <michagogo> You don't even need all of build-essential
1225 2016-10-18T19:46:11  <wumpus> that's a lot of micromanagement though. I tdoesn't hurt to install one package too many. Though it should be made clear that you don't need to install dependencies if you're going to do a depends build, just the compiler/toolchain
1226 2016-10-18T19:46:34  <wumpus> some of that is documented in depends/, but that's somewhat hidden away
1227 2016-10-18T19:47:15  <michagogo> OTOH, it's just a waste of space to install g++-mingw-w64 when g++-mingw-w64-x86-64 is enough
1228 2016-10-18T19:47:54  <michagogo> (The former basically pulls in the latter, plus -i686)
1229 2016-10-18T19:48:58  <michagogo> And I think some of the packages don't even come with build-essential, you need to install them individually anyway
1230 2016-10-18T19:49:16  <wumpus> I agree, but I think getting the high level understanding clear "depends installs the dependencies for you so you don't need to get them from apt" is more important than whether we mention one package more or less
1231 2016-10-18T19:50:03  <michagogo> In other words, IMHO, there are few enough necessary packages that it's worth just listing them rather than the metapackages that pull in supersets of some of them
1232 2016-10-18T19:50:12  <michagogo> Well, yeah
1233 2016-10-18T19:50:59  <michagogo> I'm hoping to overhaul build-windows on Thursday, if nobody else does it in the meantime
1234 2016-10-18T19:51:39  <michagogo> Also, maybe build-unix should be updated to present depends as an alternative to system deps
1235 2016-10-18T19:51:45  <wumpus> I don't think you need to be afraid anyone else will do so in the meantime, I mean no one did in the last months either :)

1241 2016-10-18T20:07:48  <wumpus> jonasschnelli: could you elaborate in #8546 what you mean with " I think its acceptable if it breaks wallets used back in 0.3.x in conjunction with IP transaction". I don't think it'd be acceptable if the client suddenly crashes if someone happens to be using a wallet that still has a pay-to-IP transaction in it.

1243 2016-10-18T20:08:17  <wumpus> I'd prefer keeping around a bit of useless code to that
1244 2016-10-18T20:08:41  <wumpus> OTOH, it's not tested anyway, so if it is safe to remove (no risk of crashes) I'm fine with it
1245 2016-10-18T20:09:17  <wumpus> to be honest I think #8564 is a bit questionable, I'm not convinced it only removed code to do with ip transactions

1270 2016-10-18T20:13:24  <Anduck> hmm... i tried it but it complained about libdb4.8++

1274 2016-10-18T20:13:43  <wumpus> these days I don't use bdb 4.8 anymore tbh
1275 2016-10-18T20:14:09  <Anduck> are there any recent/known compatibility issues with newer ones?
1276 2016-10-18T20:14:20  <wumpus> yes, still the same as always
1277 2016-10-18T20:14:28  <Anduck> ok
1278 2016-10-18T20:14:38  <wumpus> bdb 5 wallets won't work in 4.8, bdb 6 wallets won't work in 5 and 4.8
1279 2016-10-18T20:14:57  <Anduck> but it will work perfectly well otherwise?
1280 2016-10-18T20:16:11  <Anduck> --with-incompatible-bdb raises the question if it's not safe to use it at all, or if it's just simply incompatible with other major bdb versions
1281 2016-10-18T20:16:13  <wumpus> and to convert between versions one can do  db5.0_dump wallet.dat | db4.8_load wallet.dat.new  , still the same as in 2012 :)
1282 2016-10-18T20:17:30  <wumpus> I can't guarantee anything about being safe to use, but I've never heard of any inherent issues
1283 2016-10-18T20:18:20  <wumpus> it's just that different versions' databases are binary incompatible, and if you don't know about that it can be confusing
1284 2016-10-18T20:18:41  <Anduck> alright. good to know
1285 2016-10-18T20:19:45  <wumpus> I guess it'd make sense to document that better
1286 2016-10-18T20:20:04  <Victorsueca> there, back to compiling.... again.....
1287 2016-10-18T20:20:12  <wumpus> but so much stuff to do

1289 2016-10-18T20:22:52  <Victorsueca> maybe it's an overkill but way we'll know if ram was the problem
1290 2016-10-18T20:24:09  <wumpus> 16GB is hardly overkill these days
1291 2016-10-18T20:24:38  <Victorsueca> if it's supposed to be enough with 1.5 or 2....
1292 2016-10-18T20:25:42  <wumpus> that's for the compiler. The other 14GB is for windows.
1293 2016-10-18T20:25:51  <Victorsueca> lol
1294 2016-10-18T20:26:45  <Victorsueca> windows eats at most 4 GB, 2GB usually

1305 2016-10-18T20:42:53  <michagogo> Anduck: honestly, the easiest thing, I think, is to just use the depends system
1306 2016-10-18T20:44:14  <wumpus> michagogo: it is - would be nice if there waa a way to use depends *just* for berkeleydb
1307 2016-10-18T20:44:37  <michagogo> Yeah
1308 2016-10-18T20:45:03  <Victorsueca> i think there is some way to use the system library for some dependency instead f the one specified in depends
1309 2016-10-18T20:45:12  <wumpus> currently you have to either build all dependencies (including qt, which you really don't want to build statically on ubuntu) using depends or none at all
1310 2016-10-18T20:45:14  <michagogo> I mean, can you just run bdb.mk? Or does that only work when called by the main makedile?
1311 2016-10-18T20:45:48  <wumpus> maybe it's possible
1312 2016-10-18T20:46:05  <michagogo> wumpus: can you not make depends NO_QT=1 and point configure at system qt?
1313 2016-10-18T20:46:23  <wumpus> yea, but that'd stlil pull in boost
1314 2016-10-18T20:47:00  <wumpus> it's currently not a practical way to build just berkeleydb
1315 2016-10-18T20:49:16  <GitHub161> [bitcoin] laanwj pushed 9 new commits to master: https://github.com/bitcoin/bitcoin/compare/23e03f8d26d7...05998da5a7e2

1320 2016-10-18T20:49:30  <GitHub119> [bitcoin] laanwj closed pull request #8865: Decouple peer-processing-logic from block-connection-logic (master...net_processing_1) https://github.com/bitcoin/bitcoin/pull/8865
1321 2016-10-18T20:49:40  <BlueMatt> did you mean to do that?
1322 2016-10-18T20:49:44  <wumpus> yes
1323 2016-10-18T20:50:00  <BlueMatt> ok!
1324 2016-10-18T20:52:43  <wumpus> does make sense to do a bit of continuous integration tehre instead of leaving the pull open for months
1325 2016-10-18T20:52:53  <BlueMatt> true
1326 2016-10-18T20:53:10  <BlueMatt> alright, well I'll open up the next one in a sec when my fibre tests pass
1327 2016-10-18T20:53:17  <wumpus> awesome

1336 2016-10-18T21:35:20  <cfields_> BlueMatt: heh, I was reviewing it and it was merged under my feet :)
1337 2016-10-18T21:35:42  <BlueMatt> cfields_: its one of those things that can move forward but still needs posthumous acks
1338 2016-10-18T21:35:43  <BlueMatt> :p
1339 2016-10-18T21:35:52  <cfields_> BlueMatt: fwiw, looks good to me though
1340 2016-10-18T21:35:55  <cfields_> heh
1341 2016-10-18T21:36:57  <BlueMatt> posthumous acks are important :)

1362 2016-10-18T23:16:42  <sipa> i guess many things are harder if you don't use a common architecture
