16 2012-05-28 00:34:54 <gmaxwell> I've got a testnet node here managing to take 16.8 seconds to return on getmemorypool.

19 2012-05-28 00:38:17 <luke-jr> gmaxwell: is that with or without my pullreqs?
20 2012-05-28 00:40:13 <gmaxwell> Ye.s
21 2012-05-28 00:40:22 <gmaxwell> It's trunk + new testnet.
22 2012-05-28 00:41:17 <gmaxwell> haven't stuck a profiler on it but I did break into it a few times and ever time I did it was in sha256 in openssl.

41 2012-05-28 02:31:00 <gmaxwell> I just pulled the testnet reset.
42 2012-05-28 02:31:38 <gmaxwell> I've been beating on it the last few days. Works good. I added some additional test cases the testnet network.

44 2012-05-28 02:32:47 <gmaxwell> e.g. a maximum size block, and a bunch of traffic that should make for good pruning tests.
45 2012-05-28 02:32:54 <gmaxwell> I also bounced it off both difficulty rails.
46 2012-05-28 02:33:37 <gmaxwell> (and a whole 2016 block cycle with blocks timed the absolute minimum apart)
47 2012-05-28 02:37:21 <BlueMatt> gmaxwell: wanna checkpoint that?
48 2012-05-28 02:38:58 wood has joined
49 2012-05-28 02:39:17 <gmaxwell> I was contemplating adding a checkpoint and a switch that removes it and rejects the block that I did a 100k TNBTC fee in, in order to do get a balance for testnet-in-a-box style usage.

91 2012-05-28 03:53:50 <gmaxwell> thats a surprisingly unhelpful error message too.
92 2012-05-28 03:54:02 <D34TH> its all qt-sdk gives me
93 2012-05-28 03:54:12 <D34TH> The filename, directory name, or volume label syntax is incorrect.
94 2012-05-28 03:54:34 <forrestv> D34TH, maybe try putting the build directory in C:\bitcoinbuild
95 2012-05-28 03:54:44 <D34TH> on it
96 2012-05-28 03:54:45 <forrestv> the long name or weird characters are probably messing it up

332 2012-05-28 17:58:33 <Eliel_> splatster: carrying block data on a usb-stick would also open a window for compromise. Although a non-interactive one so more difficult to pull off.

334 2012-05-28 17:59:27 <Eliel_> but if someone manages to get executable payload there, it can slip a tx to their own address to go out the next time you move transactions to online system.

351 2012-05-28 18:28:01 <slush> hi, how often bitcoind rebroadcast transaction?
352 2012-05-28 18:28:30 <sipa> once every half hour, approximately
353 2012-05-28 18:28:35 <slush> I did orphaned transaction by mistake (from transaction which wasn't confirmed yet), so memory pool rejected it
354 2012-05-28 18:28:46 <slush> I suppose it will fix itself on rebroadcasting, right?
355 2012-05-28 18:29:25 <sipa> spending an unconfirmed output is perfectly valid
356 2012-05-28 18:29:37 <slush> from unconfirmed (not yet mature) block?
357 2012-05-28 18:29:52 <slush> I see this in bitcoind listtransaction: {
358 2012-05-28 18:29:52 <slush> "account" : "",
359 2012-05-28 18:29:52 <slush> "address" : " unknown ",
360 2012-05-28 18:29:52 <slush> "category" : "send",
361 2012-05-28 18:29:52 <slush> "amount" : -150.00000000,
362 2012-05-28 18:29:52 <slush> "fee" : 0.00000000,
363 2012-05-28 18:30:26 <sipa> it's from a coinbase output?
364 2012-05-28 18:30:37 <slush> yes
365 2012-05-28 18:31:01 <luke-jr> O.o
366 2012-05-28 18:31:01 BTC_Bear is now known as hbrntng!~BTC_Bear@unaffiliated/btc-bear/x-5233302|BTC_Bear
367 2012-05-28 18:31:05 <sipa> ah, that's different
368 2012-05-28 18:31:27 <sipa> it should still fix itself once the input is mature
369 2012-05-28 18:31:45 <luke-jr> [18:26:57] <slush> "address" : " unknown ", <-- what's going on here?
370 2012-05-28 18:31:49 <slush> luke-jr one your eye is bigger than second, you know? :-P
371 2012-05-28 18:32:48 <Diablo-D3> heh its a slush
372 2012-05-28 18:32:55 <slush> :)
373 2012-05-28 18:33:26 <slush> sipa: actually that block is already confirmed now, so I expect it is waiting to rebroadcasting mechanism
374 2012-05-28 18:34:00 <splatster> Address unknown? That's odd.
375 2012-05-28 18:34:02 <slush> luke-jr maybe because tx/address isn't in memory pool or even blockchain?
376 2012-05-28 18:34:11 <slush> ..in blockchain
377 2012-05-28 18:34:19 <luke-jr> slush: that's pretty normal
378 2012-05-28 18:34:35 <luke-jr> unknown address means the output is non-standard

425 2012-05-28 19:59:18 <wladston> haha
426 2012-05-28 19:59:39 <luke-jr> that's a bit slow.
427 2012-05-28 20:00:21 * luke-jr wonders where dooglus went

429 2012-05-28 20:00:46 <slush> ok, transaction has been confirmed during the dinner somehow, so everything is fine :)
430 2012-05-28 20:00:48 <Diapolo> currently no GUI patches go in and I have no clue, what happened
431 2012-05-28 20:01:20 <wladston> maybe the CPU on this server isn't that nice
432 2012-05-28 20:02:11 <wladston> my greatest worry is that sometimes bitcoind "hangs" and take a HUGE time to reply my queries
433 2012-05-28 20:02:36 <JFK911> theres lots of memory to unleak and garbages to collect

455 2012-05-28 20:26:47 <splatster> D34TH: You don't have boost installed or at least not properly.
456 2012-05-28 20:26:55 <D34TH> thnx
457 2012-05-28 20:27:05 <D34TH> do i need a specific version
458 2012-05-28 20:27:10 <D34TH> because i think i grabbed an old one
459 2012-05-28 20:27:29 <JZavala> it would be horribly mean to add a random character every few lines of code wouldnt it
460 2012-05-28 20:27:32 <JZavala> i'd never do it
461 2012-05-28 20:27:33 <splatster> D34TH: There are full build instructions including the needed dependencies in the source.
462 2012-05-28 20:27:39 <JZavala> but i can imagine it would be torture to find it

472 2012-05-28 20:35:49 <wladston> I would like to accept credit cards to let users buy bitcoin credits on my service. Any ideas on how to start ?
473 2012-05-28 20:38:00 <luke-jr> wladston: nice knowing you
474 2012-05-28 20:38:25 <luke-jr> wladston: hint: there's a very good reason nobody does that

476 2012-05-28 20:39:30 <BlueMatt> you will also get your contract with the ccs terminated as soon as they find you out
477 2012-05-28 20:39:31 <wladston> luke-jr: I wonder if there is a way to avoid it ⦠since I won't be selling the coins directly, but "credits" to use the service

481 2012-05-28 20:40:48 <luke-jr> hmm
482 2012-05-28 20:40:52 <wladston> the world runs on credit cards now, so we gotta find a way to work with that if we want to reach a big market share
483 2012-05-28 20:41:09 <luke-jr> it's tempting to make 1-txn blocks, seeing how long it takes to verify them (which delays propagationâ¦)
484 2012-05-28 20:41:30 <luke-jr> wladston: you're doing it backward :P
485 2012-05-28 20:41:37 <wladston> in brazil it's almost impossible to buy bitcoins with a bank account...
486 2012-05-28 20:42:09 <luke-jr> so sell them for cash?
487 2012-05-28 20:42:28 <_Fireball> wladston, imo, it's possible to do that like AurumXchange does, by selling "codes".
488 2012-05-28 20:42:28 <wladston> luke-jr: they are not popular in brazil *at all*
489 2012-05-28 20:42:40 <luke-jr> wladston: cash isn't?
490 2012-05-28 20:42:42 <_Fireball> then you can use codes to fill an account in an exchange of your choice
491 2012-05-28 20:43:16 <wladston> luke-jr: cash is, but how can I accept cash using the internet ?
492 2012-05-28 20:43:32 <luke-jr> wladston: why use the internet?
493 2012-05-28 20:43:36 <wladston> _Fireball: humm, taking a look at that
494 2012-05-28 20:43:37 <luke-jr> sell at storefront
495 2012-05-28 20:43:55 <BlueMatt> if you wanna charge an insane fee, you may be able to not loose too much, but then no one will use your service

500 2012-05-28 20:45:18 <wladston> I wanted my mother to use my service, for example â but she can't buy credits because she has no idea what a bitcoin is
501 2012-05-28 20:45:28 <wladston> even though I tried to explain her haha
502 2012-05-28 20:45:38 <BlueMatt> then accept paypal _and_ bitcoin?
503 2012-05-28 20:45:39 <Matt_von_Mises> if (txout.nValue < 0) then error Whats the point?
504 2012-05-28 20:45:43 <BlueMatt> though, again, chargebacks
505 2012-05-28 20:46:04 <wladston> BlueMatt: paypal would be an option
506 2012-05-28 20:46:46 <wladston> I once read a post from the guy taht made coinpal ⦠he said he had chargebacks under control
507 2012-05-28 20:46:58 <wladston> the problem was paypal's policy
508 2012-05-28 20:47:24 <BlueMatt> paypal will ban you as soon as they find out whats up, yea
509 2012-05-28 20:47:50 <BlueMatt> but if you are letting people withdraw bitcoin, ie convert to bitcoin, ccs will too

513 2012-05-28 20:51:21 <wladston> maybe okpay ?
514 2012-05-28 20:51:56 <BlueMatt> then Id think anything would work

530 2012-05-28 21:09:02 <graingert> you should probably check that

539 2012-05-28 21:10:41 <luke-jr> going back to master, it's not slow anymore; maybe only after a sync?
540 2012-05-28 21:10:57 <splatster> "right now, the block *isn't* checked" <-- Whaaaaaaaa?
541 2012-05-28 21:11:02 <luke-jr> or perhaps varies greatly based on mempool size

543 2012-05-28 21:11:14 <splatster> Why not?
544 2012-05-28 21:11:14 <luke-jr> splatster: the blocks are only checked once found

552 2012-05-28 21:12:18 <graingert> ie put tx inside might be invalid

588 2012-05-28 21:36:46 <wladston1> yup
589 2012-05-28 21:36:59 <BlueMatt> ok, so what does iotop show you, and whats bitcoind's cpu usage like?
590 2012-05-28 21:37:08 <wladston1> how to check cpu usage ?
591 2012-05-28 21:37:13 <BlueMatt> luke-jr: how is that debateable, aside from cost reasons, more mem is always better
592 2012-05-28 21:37:29 <gmaxwell> well, more memory means more power usage.
593 2012-05-28 21:37:29 <wladston1> BlueMatt: I don't have it : -bash: iotop: command not found
594 2012-05-28 21:37:35 <luke-jr> BlueMatt: cost reasons are important
595 2012-05-28 21:37:42 <gmaxwell> current hardware and OSes don't know how to turn off memory that isn't needed.
596 2012-05-28 21:37:52 <wladston1> bitcoind is taking 9% of cpu
597 2012-05-28 21:37:57 <wladston1> 4% now
598 2012-05-28 21:37:58 <BlueMatt> gmaxwell: need a lot of servers before that starts making a difference, really?
599 2012-05-28 21:38:05 <wladston1> it changes a lot

604 2012-05-28 21:38:25 <gmaxwell> BlueMatt: I dunno about that... memory is actually fairly power hungry.

610 2012-05-28 21:39:27 <BlueMatt> or, does your vps provider give you disk usage graphs

629 2012-05-28 21:44:05 <BlueMatt> gmaxwell: awww, I was having fun making cgminer run cuda...oh well, Ill go rebase
630 2012-05-28 21:44:10 <D34TH> ok so it was reading the wrong version of boost
631 2012-05-28 21:44:11 <wladston1> also another question ⦠I'm set to accept payments with 3 confirmations
632 2012-05-28 21:44:14 <D34TH> my brain is melted
633 2012-05-28 21:44:28 <wladston1> but would like to accept with 0 or 1

635 2012-05-28 21:45:04 <D34TH> like-jr mind if i ask a stupid question?
636 2012-05-28 21:45:12 <luke-jr> yes
637 2012-05-28 21:45:13 <wladston1> if I get a double spend attack, how can I react to it ?
638 2012-05-28 21:45:21 <wladston1> using bitcoind ?
639 2012-05-28 21:45:24 <D34TH> if the makefile searched for 1.0.1d openssl why does the build-msw.txt say 1.0.1b
640 2012-05-28 21:45:27 <luke-jr> but you won't know it's stupid until you ask it

643 2012-05-28 21:47:23 <luke-jr> D34TH: because nobody who's serious actually uses Windows or pays attention to build-msw.txt
644 2012-05-28 21:47:46 <D34TH> alright
645 2012-05-28 21:47:49 <D34TH> makefile hacking time
646 2012-05-28 21:48:11 <gmaxwell> D34TH: please cleanly fix those issues and submit pull requests.
647 2012-05-28 21:48:17 <BlueMatt> its probably easier to install ubuntu in a vm and cross compile than actually get windows to work, tbh...
648 2012-05-28 21:48:27 <luke-jr> BlueMatt: definitely

651 2012-05-28 21:49:18 <BlueMatt> fun thing is, in windows 8, building apps with visual studio is not an option anymore for most people, so now you _have_ to use mingw, and then its easier to cross compile

653 2012-05-28 21:49:44 <BlueMatt> lets just alienate all our devs since we dont have any good ones anyway, why dont we?
654 2012-05-28 21:49:58 <D34TH> gmaxwell done
655 2012-05-28 21:50:05 <luke-jr> well, good devs almost use Linux by definition
656 2012-05-28 21:50:09 <BlueMatt> so much for "DEVELOPERS, DEVELOPERS, DEVELOPERS, DEVELOPERS, DEVELOPERS!"
657 2012-05-28 21:50:34 <D34TH> nevermind it didnt save

659 2012-05-28 21:50:39 * luke-jr peers
660 2012-05-28 21:50:39 <gmaxwell> luke-jr: hush. We need more windows developers... and if we manage to get some good ones there we shouldn't tip them off that they'd be much happier on linux. Their loss is our gain.
661 2012-05-28 21:51:07 <luke-jr> gmaxwell: I suppose. Just speaking from experience.
662 2012-05-28 21:51:24 <BlueMatt> to be fair, its gotten 10000x easier since we switched to qt
663 2012-05-28 21:51:26 <wladston1> I used ubuntu for 6 years, now switched to mac
664 2012-05-28 21:51:48 <D34TH> there we go
665 2012-05-28 21:51:49 <BlueMatt> used to be weird transparency issues popping up with wx2.9 for no reason
666 2012-05-28 21:51:50 <wladston1> there are the downsides, but I'm pretty satisfied.
667 2012-05-28 21:52:11 <wladston1> going to commute back home guys ⦠nice work for everyone

677 2012-05-28 21:57:18 * D34TH sighs
678 2012-05-28 21:57:34 <D34TH> i cant catch a break at all
679 2012-05-28 21:58:21 <D34TH> ooh gmaxwell i found another thing, when boost compiles it saves to c:boost not C:\boost-1.47.0-mgw
680 2012-05-28 21:58:26 <D34TH> whoops
681 2012-05-28 21:58:29 <D34TH> c:\boost
682 2012-05-28 21:58:44 <D34TH> when i get my makefile hackery done i shall test it
683 2012-05-28 21:58:49 <gmaxwell> k.
684 2012-05-28 21:59:14 <BlueMatt> I think the boost-1.47.0-mgw was just a thing to force people to use 1.47 and be aware of the version
685 2012-05-28 21:59:35 <BlueMatt> also, I dont think you have to install, so you should just unzip to C:\boost-1.47.0-mgw and make there, without installing

694 2012-05-28 22:04:42 <D34TH> compiling with boost 1.50
695 2012-05-28 22:05:34 <D34TH> alot of warnings
696 2012-05-28 22:05:46 <D34TH> kinda makes me think nothing will work
697 2012-05-28 22:12:41 <Joric_> agreed boost is a serious reason to kill yourself
698 2012-05-28 22:13:37 <sipa> your nickname hardly helps, i guess

700 2012-05-28 22:14:36 <BlueMatt> were gonna need about a month of rcs to get 0.7 ready to ship, I think

705 2012-05-28 22:15:34 <luke-jr> sipa: do you have forum mod perms?
706 2012-05-28 22:15:43 <sipa> no
707 2012-05-28 22:15:46 <luke-jr> gmaxwell: ^?
708 2012-05-28 22:16:00 <BlueMatt> Im rebasing now, then Ive got one deadlock that seems like it should appear pretty often, but I cant seem to get it to trigger in DEBUG_LOCKORDER to track down, then Ill push
709 2012-05-28 22:16:24 <luke-jr> also, I took out the stupid cache in getmemorypool for benchmarking⦠git master takes over 7 minutes for ~400 txns -.-
710 2012-05-28 22:16:33 <gmaxwell> luke-jr: no only for the mining subforum.
711 2012-05-28 22:16:38 <gmaxwell> luke-jr: see.
712 2012-05-28 22:16:45 <gmaxwell> thats @#$@ broken.
713 2012-05-28 22:16:53 <luke-jr> the problem is, it's no an easy algorithm
714 2012-05-28 22:17:03 <gmaxwell> Explains my resultâ I was adding new txn between calls.
715 2012-05-28 22:17:17 <luke-jr> 0.55-1.57 seconds per transaction it seems
716 2012-05-28 22:17:20 <sipa> wait... what?
717 2012-05-28 22:17:27 <luke-jr> sipa: CreateNewBlock is SLOW
718 2012-05-28 22:17:40 <sipa> i would call a second SLOW
719 2012-05-28 22:17:53 <sipa> 7 minutes in unacceptable
720 2012-05-28 22:18:06 <luke-jr> >_<
721 2012-05-28 22:18:21 <gmaxwell> What could it possibly be doing?
722 2012-05-28 22:18:22 * luke-jr wonders how miners ever *work*
723 2012-05-28 22:18:27 <gmaxwell> Men! to your profilers!

726 2012-05-28 22:18:44 <sipa> is that just master now, or is it the same in releases?
727 2012-05-28 22:18:54 <luke-jr> sipa: didn't benchmark there at all yet
728 2012-05-28 22:19:01 <luke-jr> obviously, getting averages is slow

750 2012-05-28 22:22:17 <D34TH> wow no wonder why my vm had bad performance
751 2012-05-28 22:22:22 <D34TH> it thinks i have 8 cores
752 2012-05-28 22:22:25 <luke-jr> lol

755 2012-05-28 22:23:06 <luke-jr> oh wait
756 2012-05-28 22:23:09 <D34TH> nope amd
757 2012-05-28 22:23:13 <luke-jr> my getmemorypool times are for 1000 calls
758 2012-05-28 22:23:15 <luke-jr> forgot to mention that
759 2012-05-28 22:23:32 <D34TH> AMD Athlon II x4 640

761 2012-05-28 22:23:49 <D34TH> this thing runs like a tank
762 2012-05-28 22:24:11 <sipa> luke-jr: so, 0.42s?
763 2012-05-28 22:24:17 <luke-jr> sipa: I guess so XD
764 2012-05-28 22:24:30 <sipa> that's... slow but acceptable i guess
765 2012-05-28 22:24:35 <luke-jr> ok honestly⦠I forgot I was making 1000 calls >_<
766 2012-05-28 22:25:05 <sipa> haha
767 2012-05-28 22:25:22 <D34TH> now to figure out how to linux -> windows
768 2012-05-28 22:25:36 <luke-jr> D34TH: probably won't work inside Virtualbox <.<
769 2012-05-28 22:25:47 <D34TH> it should
770 2012-05-28 22:26:06 <D34TH> i couldnt see why not
771 2012-05-28 22:26:10 <luke-jr> D34TH: it requires hardware virtualization support
772 2012-05-28 22:26:20 <D34TH> like PAE?
773 2012-05-28 22:26:22 <luke-jr> â¦
774 2012-05-28 22:26:25 <luke-jr> like VT-x
775 2012-05-28 22:26:32 <D34TH> i have that enable
776 2012-05-28 22:26:34 <D34TH> **enabled
777 2012-05-28 22:26:39 <luke-jr> yes, but inside your VirtualBox? ;)
778 2012-05-28 22:26:42 <D34TH> VT-x/AMD-V
779 2012-05-28 22:27:28 <sipa> D34TH: official windows binaries are built using a system called gitian, that builds inside a tightly-controlled virtual machine, on Ubuntu
780 2012-05-28 22:27:29 <D34TH> "When checked, the virtualmachine will trry to make use of the host CPU's hardware virtualization extensions such at Intel VT-x and AMD-v"
781 2012-05-28 22:27:51 <sipa> D34TH: if you run Ubuntu itself already in a VM, you have two VM's stacked
782 2012-05-28 22:27:56 <D34TH> sipa do you have a iso i could get of the vm?
783 2012-05-28 22:28:05 <luke-jr> D34TH: yes, but can you run a virtual machine inside that virtual machine?
784 2012-05-28 22:28:13 <D34TH> i am running windows and have a vm of ubuntu
785 2012-05-28 22:28:21 <D34TH> i havent tried
786 2012-05-28 22:28:29 <luke-jr> D34TH: you need to have another VM of Ubuntu *inside* that VM
787 2012-05-28 22:28:39 <D34TH> why?
788 2012-05-28 22:28:48 <luke-jr> D34TH: because that's how we build Windows binaries
789 2012-05-28 22:28:52 <sipa> that's how gitian works
790 2012-05-28 22:28:54 <D34TH> dafuq
791 2012-05-28 22:29:03 <sipa> it creates a VM to build the system in
792 2012-05-28 22:29:12 <sipa> but the script to do so, requires Ubuntu
793 2012-05-28 22:29:16 <D34TH> teach me how to use it?
794 2012-05-28 22:29:28 <D34TH> what are the prereqs
795 2012-05-28 22:30:08 <sipa> i once read a howto
796 2012-05-28 22:30:14 <sipa> but not sure where it is anymore
797 2012-05-28 22:30:24 <D34TH> oh it uses qemu

800 2012-05-28 22:30:52 <sipa> but if it needs to do CPU emulation, builds will probably take days :)

809 2012-05-28 22:32:16 <luke-jr> 0.00321 sec per gmp isn't too bad

825 2012-05-28 22:39:07 <luke-jr> 2x seems reasonable for what it's doing, IMO
826 2012-05-28 22:39:34 <sipa> well, right now, i don't think any block ever produced should fail that test
827 2012-05-28 22:39:35 <luke-jr> building the block in the first place basically checks all the transactions; verifying them again as a whole block is liable to take just as long

829 2012-05-28 22:39:40 <luke-jr> correct
830 2012-05-28 22:39:50 <luke-jr> I wrote this to help #1240 get merged ;)

834 2012-05-28 22:40:29 <sipa> i like the idea of checking the blocks, though, don't get me wrong
835 2012-05-28 22:40:31 <luke-jr> combined with #1240, it adds functionality
836 2012-05-28 22:40:44 <luke-jr> #1240 enables adding fees to stuck transactions, for example
837 2012-05-28 22:41:01 <D34TH> hmm unable to bind socked 3142

839 2012-05-28 22:41:23 <sipa> did you start it using sudo?
840 2012-05-28 22:41:28 <D34TH> and does gitian need wxwidgets i thought bitcoin switched over to qt
841 2012-05-28 22:41:29 <D34TH> yes
842 2012-05-28 22:41:33 <D34TH> i actually ran it as root
843 2012-05-28 22:41:43 <sipa> no no, that's just outdated
844 2012-05-28 22:41:43 <luke-jr> D34TH: gitian only needs wxwidgets to build 0.4.x
845 2012-05-28 22:42:35 <BlueMatt> why bother running under gitian? just reading the .ymls and executing the commands manually isnt really very hard
846 2012-05-28 22:42:59 * sipa never dared to touch that cross-compile cod
847 2012-05-28 22:43:01 <sipa> e

892 2012-05-28 23:09:22 <luke-jr> there is no 0.7.0
893 2012-05-28 23:09:22 <D34TH> because d doesnt exist
894 2012-05-28 23:09:33 <D34TH> you know what i mean
895 2012-05-28 23:09:45 <sipa> D34TH: that yml builds and packages openssl, it doesn't need to install anything

911 2012-05-28 23:19:41 <BlueMatt> sipa: for the life of me, I cant find it...I know its in ResendWalletTransactions, so just trigger that and replace the callback in RelayWalletTransaction with RelayMessage under DEBUG_LOCKORDER, it should show up
912 2012-05-28 23:19:41 <BlueMatt> Im pretty sure it was an IsTransactionFromMe call that locked cs_wallet, but I cant find where either will deadlock
913 2012-05-28 23:24:40 <D34TH> anyone have a fresh bitcoin-deps zip they wanna send
914 2012-05-28 23:24:50 <sipa> BlueMatt: sounds reasonable that there is a chance for deadlock there
915 2012-05-28 23:25:25 <sipa> BlueMatt: but why a special global wallet queue, instead of adding it to blockstore?
916 2012-05-28 23:25:49 <sipa> a message to be relayed sounds like something that can pass through the hub

920 2012-05-28 23:30:13 <BlueMatt> sipa: dunno, seemed saner to add a few functions to wallet.cpp that are only used once and then one line to init.cpp instead of yet another callback to cblockstore just to fix one deadlock
921 2012-05-28 23:30:49 <sipa> BlueMatt: i don't see it that way - imo wallet should never talk directly to network anyway

924 2012-05-28 23:33:25 <BlueMatt> sipa: hmm...not sure how to do it, a relaymessagenow callback in cblockstore doesnt make sense much to me either, though we really shouldnt be manually relaying anything in wallet in any way that we dont do normal txes...
925 2012-05-28 23:33:25 * BlueMatt goes to see about manually relaying everything in memory again automatically on the same schedule wallet used to have
926 2012-05-28 23:35:13 <Joric> '<wladston> what is better to prevent against double spending ? opening port 8333 or closing port 8333' -- #bitcoin
927 2012-05-28 23:35:55 <BlueMatt> neither really has any effect, but open it
928 2012-05-28 23:36:41 <wladston> BlueMatt: why ?
929 2012-05-28 23:36:59 <BlueMatt> it helps the network stay healthy
930 2012-05-28 23:37:21 <wladston> hmm, ok, opened here.

932 2012-05-28 23:39:11 <gmaxwell> Opening the port should never hurt you except for perhaps a little increase in risk of targeted DOS attacks (which you can solve using two nodes), and a small increase in bandwidth usage. It can help you by making you somewhat more resistant to isolation attacks, and it helps you be generally helping the bitcoin network.
933 2012-05-28 23:39:45 <sipa> wow, on logdb... the initial 100 pool key generation is instantaneous
934 2012-05-28 23:39:45 <wladston> awesome. I have very few connections, even with my port open ...
935 2012-05-28 23:40:09 <sipa> wladston: keep it open, connection will come as peers learn your address
936 2012-05-28 23:40:43 <wladston> sipa: aye
937 2012-05-28 23:41:07 <gmaxwell> sipa: at least on some systems the use of mlock makes it non-instant even if the database is on tmpfs.
938 2012-05-28 23:41:47 <gmaxwell> wladston: the few connections is because we currently have a good ratio of listeners to non-listeners. If bitcoin gets another overnight popularity burp like we had last year we can run out of listeners fast.
939 2012-05-28 23:41:54 <sipa> i wonder what bdb is doing that could make it so slow
940 2012-05-28 23:42:07 <gmaxwell> sipa: sync writes.

972 2012-05-28 23:56:21 <D34TH> luke you should compile a windows build for me of the latest git
973 2012-05-28 23:56:24 <gmaxwell> wladston: because it records a mapping of transactions to IP addresses.
974 2012-05-28 23:56:57 <gmaxwell> arguably it's doing users a service by showing that you don't have much privacy unless you use torâ so perhaps I'd think it were okay if not for the connection slot waste.
