2 2012-05-18 00:01:25 <gmaxwell> It takes a _lot_ more gates to implement e.g. a floating point multiply than the modular additions we use. The ratio is only 'constant' on general purpose CPUs because they try to be somewhat balanced architectures.
3 2012-05-18 00:02:27 <gmaxwell> er, but I don't see any harm in the bogometric.
4 2012-05-18 00:02:35 <gmaxwell> It's going to be BS no matter how you cut it.
5 2012-05-18 00:03:04 <tcatm> yep. On the same amount of silicon you can either fit x integer processing circuits or y floating point circuits..

36 2012-05-18 01:44:48 <gmaxwell> luke-jr: there is already a fair bit of "block chain!"
37 2012-05-18 01:45:00 <BlueMatt> jgarzik: the multi-process stuff you were talking about earlier wrt to cblockstore is the idea, or end goal...cblockstore is a first step (as the pull says), it still has a way to go to be cleaned up, but I got it to a clean stopping point and thought I might as well try for merge to see if anyone was even interested, but...
38 2012-05-18 01:47:41 <BlueMatt> jgarzik: the whole kitchen sink problem is because the idea of the first step that cblockstore is, is to split off the net crap in main.cpp and clean up the globals mess first, then work on cleaning it all up into something 10000x nicer
39 2012-05-18 01:48:00 <BlueMatt> so the goal is to make a kitchen sink that can later be split up into pieces
40 2012-05-18 01:48:11 <BlueMatt> the idea was first to split net/wallet/main(aka cblockstore)
41 2012-05-18 01:48:34 <BlueMatt> and net/main was the first split, with wallet somewhat split as well
42 2012-05-18 01:50:04 <BlueMatt> I havent bothered coding further in the past (how many months has cblockstore been sitting there now?) because it wasnt merged and I didnt have time, I didnt want to go tooooo far overboard on pull size
43 2012-05-18 01:51:26 <BlueMatt> anyway...back to debugging the old pf-based router and its random packet loss...
44 2012-05-18 01:53:25 <BlueMatt> well, aside from the parallel chain checking stuff, but thats just because I wanted to add performance improvement to the pull and not just redesign
45 2012-05-18 01:53:41 <BlueMatt> anyway...if you hate it too much to merge, Ill drop it and do something else

53 2012-05-18 01:58:36 <luke-jr> I was pretty disappointed when you decided to drop it, tbh

59 2012-05-18 02:05:07 <jgarzik> I do understood it takes a step or nine to get there

62 2012-05-18 02:07:03 <gmaxwell> Hm. I don't think that I really would have split further than wallets and blockchain/p2p... simply because you can define the blockchain<->network protocol as the current p2p protocol, and the null program is then your network program for the p2p network.
63 2012-05-18 02:08:57 <BlueMatt> i prefer it mostly because a vuln in the p2p client only means you can block new blocks from getting added, not changing the chain itself

67 2012-05-18 02:10:34 <BlueMatt> ok, I think the pull is sane, be careful when building if you have some objects not built with DEBUG_LOCKORDER/DEBUG_LOCKCONTENTION and some with
68 2012-05-18 02:11:09 <BlueMatt> oh, wait, no need to make stuff before b39 work
69 2012-05-18 02:13:09 <gmaxwell> I think debug lockorder is still broken.
70 2012-05-18 02:13:31 <BlueMatt> it wasnt on the plane (after the commit titled Fix DEBUG_LOCKORDER)
71 2012-05-18 02:13:39 <gmaxwell> oh. missed that one!
72 2012-05-18 02:15:32 Snapman is now known as Snapman[afkers]
73 2012-05-18 02:15:48 <jgarzik> gmaxwell: yeah, it is debatable whether network is a separate entity, or should be within the conceptual "blockchain server"
74 2012-05-18 02:16:54 RainbowDashh is now known as ONLY
75 2012-05-18 02:17:01 ONLY is now known as RainbowDashh
76 2012-05-18 02:17:18 * luke-jr thinks it should be separate, since there's little harm in it and a lot of potential risk gone
77 2012-05-18 02:17:31 <gmaxwell> In any case, thats down the roadâ the wallet blockchain step is obviously higher priority and a bigger win (due to running N:1 wallets to blockchains, and the privsep)
78 2012-05-18 02:17:47 <luke-jr> yeah
79 2012-05-18 02:17:58 <BlueMatt> yea, cleaner wallet/chain is next after cblockstore
80 2012-05-18 02:18:03 Snapman[afkers] is now known as Snapman
81 2012-05-18 02:18:11 <BlueMatt> (atleast not callbacks to wallet, but its pretty close)
82 2012-05-18 02:18:18 <gmaxwell> luke-jr: it has risk too. Breaking network communications can leave you on forksâ and if the blockchain is the only one doing e.g. script validation a lot of harm could just tunnel through (and if they both do, again potential forks)

130 2012-05-18 04:14:10 <gmaxwell> Hazards of coinbase triggered feature switchover, p2pool just suffered the blockchain equivilent of a boiling liquid expanding vapor explosion.
131 2012-05-18 04:14:40 <luke-jr> gmaxwell: ?
132 2012-05-18 04:15:18 <gmaxwell> luke-jr: bug in a corner case bit of latest protocol code which was triggered after p2pool crossed the 95% switchover threshold but fell below it.
133 2012-05-18 04:15:29 <gmaxwell> Caused upgraded peers to reject their own shares.
134 2012-05-18 04:15:52 <luke-jr> O.o
135 2012-05-18 04:15:58 <gmaxwell> amusinglyâ it shouldn't have harmed their ability to mine bitcoins, they all just became donor nodes to random unupgraded nodes. :)
136 2012-05-18 04:16:13 <sipa> jgarzik: with DB_HASH, does BDB use its own hash function, or does it expect hashed keys to be passed in?
137 2012-05-18 04:16:16 <Tril> allright what's a v0.6.2.2-dirty-beta
138 2012-05-18 04:16:34 <gmaxwell> it should self correct once the fixed nodes produce enough shares.
139 2012-05-18 04:16:47 <weex> when you say upgrade gmaxwell, you mean the latest security upgrade?
140 2012-05-18 04:16:48 <gmaxwell> Tril: naughty you running dirty dirty code *wink*
141 2012-05-18 04:17:01 <Tril> gmaxwell: which you told me to (what is it?)
142 2012-05-18 04:17:12 <sipa> Tril: dirty = from a source tree that was not entirely clean (modifications not in commits)
143 2012-05-18 04:17:13 <gmaxwell> weex: no, nothing to do with bitcoin.
144 2012-05-18 04:17:35 <gmaxwell> sipa: I think the dirty detection is somewhat lossy, since I've seen that tag on code that was probably clean... didn't interest me enough to check.
145 2012-05-18 04:17:35 <weex> oh the p2pool program?

149 2012-05-18 04:18:40 <sipa> gmaxwell: that may well be - once gitian was able to build without the dirty tag, it was fine to me
150 2012-05-18 04:19:19 <Tril> sipa: shouldn't be I did git clone, git checkout 0.6.2, build it (64-bit), make clean, scp to 32-bit machine machine, then built it again. Make clean doesn't stop it from being dirty?
151 2012-05-18 04:19:22 spq has joined
152 2012-05-18 04:19:58 <gmaxwell> it shouldn't be dirty unless you actually edited some of the files after doing the checkout... but don't worry about it, the detection is probably just hyperactive.
153 2012-05-18 04:20:12 <sipa> Tril: do both 32 and 64 bit builds have the dirty tag?
154 2012-05-18 04:20:20 <gmaxwell> The reason for that tag is so when you ask for support we know to ask you what evil patches you've applied.
155 2012-05-18 04:20:40 <luke-jr> network is 6.5% secure against CVE-2012-2459

159 2012-05-18 04:21:09 <sipa> Tril: scp may have messed up timestamps
160 2012-05-18 04:21:48 <sipa> seeds is not very reliable, as it does not contain addresses of nodes that are frequently off
161 2012-05-18 04:22:34 <luke-jr> Unfortunately, while my OSX zlib and minipnpc builds are deterministic, the crosscompiler, bdb, and openssl builds are not :<
162 2012-05-18 04:22:37 <sipa> well, it is reliable, but for weighted data (counting active nodes more strongly)
163 2012-05-18 04:22:46 <luke-jr> sipa: those don't matter much afaik
164 2012-05-18 04:22:53 <sipa> luke-jr: ah, too bad :(
165 2012-05-18 04:22:59 <gmaxwell> luke-jr: oh you can cross comple for OSX?

169 2012-05-18 04:24:15 <sipa> doesn't apple use clang these days?
170 2012-05-18 04:24:23 <luke-jr> shrug
171 2012-05-18 04:25:43 <luke-jr> I'm aiming for max compatibility, not "what apple does"
172 2012-05-18 04:25:44 <luke-jr> :p
173 2012-05-18 04:26:59 <sipa> no, but it'll probably take a lot of maintanence work just to keep it working
174 2012-05-18 04:27:14 <sipa> impressive that some parts already work

269 2012-05-18 08:56:46 <Eliel> moa7: those symptoms sound similar to the attack the latest release was supposed to fix. I wonder if your version has th fix since it's got -beta attached the end of the version.
270 2012-05-18 08:56:50 <rebroad> moa7 that is interesting...
271 2012-05-18 08:57:14 <moa7> all clients are beta ... as far as i'm aware

293 2012-05-18 09:24:13 <Eliel> that depends on which users you want to have access to it. If just one user, you can change the owner. Alternatively you can give a group access to the folder. Third option is to make it public.
294 2012-05-18 09:24:38 <t7> ah chown
295 2012-05-18 09:24:40 <Eliel> you can use the chown command to do the first two and chmod command to alter the access rights

377 2012-05-18 13:26:18 <TD> it seems the version i have is not new enough but there's no version check in the build
378 2012-05-18 13:26:36 <TD> i seem to have 1.49
379 2012-05-18 13:27:52 <sipa> that's certainly new enough (i believe the PPA builds are done using 1.37, i have 1.46, and i'm sure several other versions are used as well)
380 2012-05-18 13:27:56 <TD> ok

383 2012-05-18 13:28:45 <TD> inside message_queue.hpp i get another error, so maybe my boost is broken somehow

387 2012-05-18 13:29:14 <sipa> it's possible someone recently broke something for OSX

391 2012-05-18 13:30:27 <TD> seems like it may be a 32 vs 64 bit snafu again
392 2012-05-18 13:30:29 * TD rebuilds as 64 bit
393 2012-05-18 13:30:34 <TD> let's see if it makes any difference
394 2012-05-18 13:30:42 <sipa> afaik gavin does the OSX builds for 32-bit
395 2012-05-18 13:30:58 <TD> yeah. i think when i set things up i ended up with 64 bit builds of the dependencies
396 2012-05-18 13:31:09 <TD> so now i always have to remember to build as 64 bit. rerunnnig qmake reverts it to 32 bit
397 2012-05-18 13:31:11 <TD> sigh ...
398 2012-05-18 13:31:11 <gavinandresen> yes, I have macports build everything 32-bit i386-only
399 2012-05-18 13:31:30 <gavinandresen> The get_rounded_size problem sounds familiar....
400 2012-05-18 13:31:39 <TD> ah, there he is. i was about to compliment you on the new github profile pic, very professional looking :-)
401 2012-05-18 13:32:41 <TD> gavinandresen: i didn't see any obvious bugs with the cache, but yeah i think the eviction policy could use a bit more discussion. also i'm not really a fan of code like (if r.first) return r.second;
402 2012-05-18 13:32:43 <TD> otherwise lgtm
403 2012-05-18 13:32:52 <TD> oh
404 2012-05-18 13:33:09 <TD> the 200 bytes per cache entry
405 2012-05-18 13:33:09 <TD> i
406 2012-05-18 13:33:10 <TD> presume tha
407 2012-05-18 13:33:19 <TD> does that include the overhead of std::map ?
408 2012-05-18 13:33:52 <gavinandresen> yes, I was generous, it is 32 byte hash, 75 byte signature, 65 byte public key
409 2012-05-18 13:33:59 <gavinandresen> ... so lots of space for map overhead
410 2012-05-18 13:34:02 <TD> cool
411 2012-05-18 13:34:23 <TD> maybe remark on how 200 bytes was arrived at in the comment
412 2012-05-18 13:34:49 <gavinandresen> RE: r.first/r.second: what's your favorite C++ paradigm for returning both a result and a "have-result" code?
413 2012-05-18 13:35:27 <gavinandresen> I could change it to match the rest of the code and pass in a reference to the result....
414 2012-05-18 13:35:44 <TD> some libraries have a Maybe<T> or Optional<T> type, somewhat a la haskell. alternatively just struct FooResult { boolean success; boolean valid; } or something
415 2012-05-18 13:36:27 <gavinandresen> ah, Boost.Optional....
416 2012-05-18 13:36:30 <sipa> also, pointers have an implicit "no-data" value, NULL
417 2012-05-18 13:36:46 <TD> yeah, but they also add memory management problems. returning a value type feels right
418 2012-05-18 13:36:52 <TD> it's just a question of how to make the code as readable as possible
419 2012-05-18 13:37:01 <sipa> (i didn't check the actual code yet)
420 2012-05-18 13:37:20 <sipa> a Maybe type certainly sounds perfect if it exists
421 2012-05-18 13:37:30 <gavinandresen> http://www.boost.org/doc/libs/1_38_0/libs/optional/doc/html/boost_optional/examples.html#boost_optional.examples.optional_return_values
422 2012-05-18 13:37:51 <TD> yep
423 2012-05-18 13:37:54 <gavinandresen> in for a penny, in for a pound, right?
424 2012-05-18 13:39:13 <TD> looks like then you can do if ((fValid = GetSigCache(...)) return *fValid;
425 2012-05-18 13:39:16 <TD> or something like that
426 2012-05-18 13:39:32 <TD> my god the documentation for this thing is crazy
427 2012-05-18 13:39:35 <TD> they wrote an entire book on it
428 2012-05-18 13:40:30 <TD> sipa: got an IPv6 connection handy?
429 2012-05-18 13:40:45 <TD> sipa: i'm wondering if you can connect to my node or if i'm firewalled off (most likely)
430 2012-05-18 13:41:18 <gavinandresen> ok, I'm looking at optional.hpp and I'm getting scared....

438 2012-05-18 13:46:26 <BlueMatt> TD: getting connection timeout
439 2012-05-18 13:46:49 <TD> ok
440 2012-05-18 13:46:54 <gavinandresen> #include <boost/optional.h> pulls in almost 31,000 lines of code
441 2012-05-18 13:46:58 <TD> probably we drop inbound connections on 8333 at the border
442 2012-05-18 13:47:01 <TD> i'll try connecting outbound
443 2012-05-18 13:47:09 <TD> gavinandresen: er, wow. how did they manage that??

452 2012-05-18 13:48:01 <gavinandresen> ok, I'm backing away slowly from optional.hpp ....
453 2012-05-18 13:48:18 <sipa> an Optional<T> should be maybe 20 lines to implement...
454 2012-05-18 13:48:53 <gavinandresen> yes, but them we forevermore have to answer people asking "why not just use boost::Optional ?

459 2012-05-18 13:50:32 <Dagger2> talking of v6, what's up with 2a02:348:5e:5a29::1? it's the one and only v6 DNS seed, but it's refusing connections
460 2012-05-18 13:50:33 <TD> sipa: am i supposed to surround with braces or something? i tried with -connect=2001:6a8:200:b::2 but it doesn't seem to be working
461 2012-05-18 13:50:44 <sipa> TD: try braces around it

463 2012-05-18 13:50:53 <BlueMatt> one sec
464 2012-05-18 13:51:01 <BlueMatt> anyone have any 24/7 ipv6 nodes?
465 2012-05-18 13:51:07 <TD> i might be able to bring one online
466 2012-05-18 13:51:14 <Dagger2> (I'm being awkward and trying to bring up a node on a v6-only machine, and it's getting nowhere as a result)
467 2012-05-18 13:51:23 <TD> sipa: right that works

469 2012-05-18 13:51:58 <kinlo> I might also be able to maintain an ip6 node
470 2012-05-18 13:52:15 <sipa> there's a -onlynet=ipv6 option, if you like
471 2012-05-18 13:52:16 <kinlo> should the need be there

484 2012-05-18 13:54:57 <TD> ok
485 2012-05-18 13:55:01 <sipa> luke-jr: could be, it's far less tested on windows
486 2012-05-18 13:55:34 <sipa> TD: it seems your bitcoind did not manage to find out its own IPv6 address
487 2012-05-18 13:55:35 <Dagger2> (specifically www.showip.com; 2a01:608:ffff:2872::10 is dead, despite still being published in DNS)
488 2012-05-18 13:55:45 <TD> the sync bar went away? :(
489 2012-05-18 13:56:03 <TD> sipa: it does that using IRC or something, no?
490 2012-05-18 13:56:10 <TD> sipa: so if you use -connect how does it find out its own address
491 2012-05-18 13:56:42 <sipa> TD: oh, if you use -connect it disables listening, so it will never announce its own address
492 2012-05-18 13:56:45 <TD> yeah

499 2012-05-18 13:57:19 <kinlo> ah good, that was still an open question for me wether my hidden bitcoin node was announcing it's address or not
500 2012-05-18 13:58:06 <sipa> kinlo: try connecting to me, and i'll tell you what it announces

507 2012-05-18 14:00:36 <kinlo> sipa: do ask for it or I will forget
508 2012-05-18 14:00:38 <Diapolo> sipa: is [2001:6a8:200:b::2] a testnet node or on normal net?
509 2012-05-18 14:00:51 <sipa> normal

524 2012-05-18 14:05:25 <Diapolo> ?
525 2012-05-18 14:05:28 <sipa> what is that 'bin' doing inside my address?

582 2012-05-18 14:22:33 <luke-jr> moa7: 0.5.99 was never stable
583 2012-05-18 14:22:45 <moa7> so which one was?
584 2012-05-18 14:22:49 <luke-jr> moa7: latest stable: 0.6.2, 0.6.0.7, 0.5.5, 0.4.6
585 2012-05-18 14:22:55 <moa7> bitcoind?
586 2012-05-18 14:23:04 <luke-jr> yes
587 2012-05-18 14:23:40 <sipa> moa7: there was never even a 0.5.99 released - that's the internal version number used for builds done from code during 0.6.0's merge window
588 2012-05-18 14:23:47 <luke-jr> 0.6.2 is most likely to recover from stuck blockchain
589 2012-05-18 14:24:16 <sipa> any 0.5.99 you're running is most certainly broken in many ways

614 2012-05-18 14:31:41 <sipa> server=1 means you want to run an rpc server
615 2012-05-18 14:31:45 <moa7> http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.2/ so source from here is stable?
616 2012-05-18 14:31:49 <sipa> that's entirely independent from the p2p network
617 2012-05-18 14:31:54 <sipa> moa7: yes
618 2012-05-18 14:32:03 <Diapolo> sipa: you are right
619 2012-05-18 14:32:13 <sipa> moa7: but you can use git just find; just run "git checkout v0.6.2" and then build
620 2012-05-18 14:32:15 <moa7> why does it build with weurf version number?
621 2012-05-18 14:32:23 <sipa> weurf?
622 2012-05-18 14:32:27 <moa7> weird
623 2012-05-18 14:32:44 <sipa> you mean the vCLIENT_VERSION_MAJOR.... thing?
624 2012-05-18 14:32:58 <sipa> low priority bug for non-git builds of 0.6.2; fixed in 0.7.0
625 2012-05-18 14:32:59 <moa7> ya
626 2012-05-18 14:33:26 <moa7> kind of confusing if you want to know what version you are running ...
627 2012-05-18 14:33:31 <sipa> i know
628 2012-05-18 14:33:44 <sipa> Joric: don't think anything changed
629 2012-05-18 14:34:13 <Diapolo> ahh I need to add an IPv6 fw rule, didn't know my router allows this ^^
630 2012-05-18 14:35:18 <moa7> so source forge and git checkout v0.6.2 will be identical?
631 2012-05-18 14:36:31 <Joric> sipa, maybe chrome has changed
632 2012-05-18 14:37:24 <Joric> there are a few chrome rpc extensions neither of those works now

641 2012-05-18 14:47:46 <sipa> moa7: that's not really the source that differs, but there's a script that determines at compile time what version you're running, and in 0.6.2 it fails for non-git builds
642 2012-05-18 14:47:50 <sipa> the code is identical

685 2012-05-18 15:21:55 <gmaxwell> I wonder if bitcointalk and other bitcoin sites should display active alerts.

690 2012-05-18 15:22:53 <drizztbsd> lol, it's not MY pool. it's the p2pool global stats
691 2012-05-18 15:22:56 <gmaxwell> All the nodes did a concurrent automatic switchover (of a kind we've proposed for bitcoin but never done) and there was a bug.
692 2012-05-18 15:23:26 <luke-jr> gmaxwell: imo, all this means is the obvious "we should testnet it before deploying" :P
693 2012-05-18 15:23:35 <drizztbsd> is eligius decentralized mining made also on python?
694 2012-05-18 15:24:10 <kinlo> drizztbsd: eligius has a central server, luke really should explain the decentralized part of his pool coz I don't get it :)

732 2012-05-18 15:40:22 <forrestv> gavinandresen, it used a flag, and when the flag was in 95% of previous shares, it switched

749 2012-05-18 15:45:46 <forrestv> gavinandresen, looks good... p2pool used some of those ideas: the "flag" was a version field in shares, and clients started warning users when an unsupported version was in 50% of recent shares
750 2012-05-18 15:46:40 <gavinandresen> forrestv: so was the switch-back bug just a plain-old implementation bug, or a problem with the general idea of using count-of-previous-blocks-in-best-chain as the criteria to switch?
751 2012-05-18 15:47:33 <gavinandresen> Or, in other words, is there some block-reorg corner case that you tripped over that I haven't thought of....
752 2012-05-18 15:48:04 <forrestv> implementation bug- there was a rule that said that an old-share can't follow a new-share, but it was only partially enforced
753 2012-05-18 15:48:17 <gmaxwell> ...But instead of a couple of early adopters going 'ouch this hurts' the whole thing came to a screeching halt.
754 2012-05-18 15:48:20 <forrestv> so people mined old-shares when the version count went down, but none of them validated

757 2012-05-18 15:49:39 <gmaxwell> There were also two thresholds in this systemâ one that made the change admissable and the other that made it happen, allowing e.g. if we get stuck under the lower threshold we could manually trigger a switch.
758 2012-05-18 15:49:57 <gmaxwell> (er stuck under the higher one rather)
759 2012-05-18 15:50:38 <forrestv> with a system as large as bitcoin, someone would manually trigger the switch unless there were some other restriction, like a special signature or hashed secret
760 2012-05-18 15:51:01 <gmaxwell> I dunno about that. You couldn't assume they wouldn't at least.

789 2012-05-18 16:23:31 <jgarzik> gmaxwell: yeah, leaving around old addr.dat is intentional
790 2012-05-18 16:23:57 <jgarzik> gmaxwell: less code, it will eventually disappear as ppl upgrade, and it might be nice to have it around if you downgrade
791 2012-05-18 16:25:36 <eian> is libbitcoin still in beta?
792 2012-05-18 16:25:40 <eian> Is it stable yet?
793 2012-05-18 16:25:56 <jgarzik> gmaxwell gavinandresen: speaking of database files... I am moving txhash.dat, blkhash.dat, blkmeta.dat and blk????.dat into blockchain/ subdirectory (sipa suggestion). the code will re-index upon first upgrade. it will pop up a "this will take a LONG time to upgrade db" dialog with InitWarning().
794 2012-05-18 16:27:34 <gmaxwell> jgarzik: are you going to split the db envrioment at the same time (or have you already done this?)

800 2012-05-18 16:30:50 <sipa> jgarzik: will reindexing mean copying blk0001.dat?
801 2012-05-18 16:30:59 <sipa> or do you move the file, and reindex it on-the-fly

803 2012-05-18 16:32:17 <sipa> gavinandresen: any reason why ExtractAddresses doesn't use ExtractAddress for the single-sig case?
804 2012-05-18 16:32:54 <gavinandresen> sipa: let me look, see if it jogs my memory
805 2012-05-18 16:33:23 <jgarzik> sipa: unfortunately I think the existing code works best if you rewrite blk????.dat along with the rest
806 2012-05-18 16:33:42 <jgarzik> sipa: i.e. LoadExternalBlockFile() calls ProcessBlock(), which ... stores in blk????.dat as well as indices
807 2012-05-18 16:33:53 <jgarzik> sipa: I could reindex, sure, but that won't use the existing code
808 2012-05-18 16:34:13 <sipa> jgarzik: ok
809 2012-05-18 16:34:22 <sipa> jgarzik: fine for now, i guess
810 2012-05-18 16:34:32 <gmaxwell> Just means that we need to have a disk space free guard of 2x blk???.dat.
811 2012-05-18 16:34:37 <sipa> reindexing on-the-fly would certainly be harder
812 2012-05-18 16:34:49 <gmaxwell> what does LoadExternalBlockFile do with multiple block files?
813 2012-05-18 16:35:13 <sipa> gmaxwell: it just processes all blocks found in the file one by one, as if they were received by network
814 2012-05-18 16:35:34 <gavinandresen> sipa: going the other way, having ExtractAddress call ExtractAddresses would probably be the easier refactor
815 2012-05-18 16:36:13 <gavinandresen> sipa: ... and if I recall correctly I didn't do that so backporting would be easier.
816 2012-05-18 16:36:45 <sipa> gavinandresen: i'm splitting CBitcoinAddress into CKeyID, CScriptID, CTxDestination (variant of the former two), and swap the script->base58 dependency around
817 2012-05-18 16:37:14 <gavinandresen> gulp. Ok.... (CBitcoinAddress is what made backporting a pain)
818 2012-05-18 16:37:23 <sipa> so we don't need base58-depending code to pass addresses around
819 2012-05-18 16:38:30 <luke-jr> sipa: is there a way for users to disable IPv6 binding?
820 2012-05-18 16:38:35 <luke-jr> eg, in the config file
821 2012-05-18 16:38:52 <sipa> luke-jr: -onlynet=ipv4
822 2012-05-18 16:39:30 <luke-jr> sipa: I think my next-test predates that option
823 2012-05-18 16:39:41 <luke-jr> guess I'll need to rebuild to debug this further
824 2012-05-18 16:40:09 <sipa> there used to be -blocknet=... instead of -onlynet, but i'm not sure whether it disables binding (don't think so)
825 2012-05-18 16:42:12 <luke-jr> sipa: yes, it looks like this version just binds IPv6 localhost always
826 2012-05-18 16:42:46 <luke-jr> forrestv: poke
827 2012-05-18 16:43:42 <sipa> luke-jr: oh, is it that old; yes, before -bind was introduced it always just listened on IPv6, which doesn't work on platforms where the v6 and v4 stacks are separated (like winxp)
828 2012-05-18 16:44:16 <forrestv> luke-jr, ?
829 2012-05-18 16:44:45 <luke-jr> forrestv: gmaxwell was hoping you'd comment on/ACK #936 again

834 2012-05-18 16:52:09 <eian> "Another idea is to reuse the energy instead of (or in addition to) the computation result. Every computation converts electricity into heat pretty efficiently. Therefore, PoW could very well be used to help heat buildings."

837 2012-05-18 16:53:00 <jgarzik> eian: not strange, that is a common data center thought in general. data centers generate a lot of heat energy
838 2012-05-18 16:53:43 <gavinandresen> I've been saying I want a mining space heater for my office for the last two winters
839 2012-05-18 16:53:54 <eian> hahaha :)

854 2012-05-18 16:56:46 <luke-jr> the problem is, how do you stop people from opening them up and taking the radeons?

856 2012-05-18 16:57:18 <sipa> luke-jr: that's why you put a specialized ASIC in it
857 2012-05-18 16:57:29 <luke-jr> sipa: but ASICs don't generate as much heat?
858 2012-05-18 16:57:30 <jgarzik> a single boost backtrace line in gdb often fills half the lines in a terminal window

866 2012-05-18 17:03:08 <luke-jr> gavinandresen: doing inexpensive checks before expensive ones seems useless to me, as long as it's not any more difficult to pass the inexpensive checksâ¦
867 2012-05-18 17:03:37 <luke-jr> that is, an attacker would just make their CPU-consuming spam pass all the simple checks and then fail the last sig chck
868 2012-05-18 17:03:53 <luke-jr> and it doesn't cost them any more to make
869 2012-05-18 17:04:05 <gavinandresen> luke-jr: failing a signature check gets them banned
870 2012-05-18 17:04:38 <luke-jr> ah
871 2012-05-18 17:04:46 <luke-jr> ok, that makes sense then
872 2012-05-18 17:06:33 <forrestv> luke-jr, why are you using AnyTxToJSON? is any of that data actually useful..?

874 2012-05-18 17:08:48 <forrestv> mm.. it complicates the output quite a bit and is redundant.. someone can just parse the data if they really care
875 2012-05-18 17:09:23 <luke-jr> parsing the data won't tell you about inputs or wallet info

955 2012-05-18 19:19:50 <nadrimajstor_> Hello everyone,
956 2012-05-18 19:21:17 <nadrimajstor_> I tried google but no luck. I'we got bitcoin 0.6.2 win32 running at Win7 64 bit
957 2012-05-18 19:21:57 <nadrimajstor_> From time to time, bitcoin fill up my upload bandwith to the top.
958 2012-05-18 19:22:39 <sipa> jgarzik: i did all my bdb-stresstests using it, for a few months
959 2012-05-18 19:24:49 <sipa> jgarzik: it's -loadblock=, by the way
960 2012-05-18 19:25:32 <gmaxwell> nadrimajstor_: disabling listening.
961 2012-05-18 19:25:58 Joric has joined
962 2012-05-18 19:29:57 <nadrimajstor_> The issues is, as my upload rate is only 35kBytes/sec that bitcoin easily fills up, making eg. web browsing really slow.. And it stays filled up for hours.
963 2012-05-18 19:30:10 <sipa> nadrimajstor_: try -nolisten, indeed
964 2012-05-18 19:30:27 <sipa> nadrimajstor_: your problem is probably caused by someone trying to download the blockchain from you
965 2012-05-18 19:30:34 Guest30328 has joined
966 2012-05-18 19:31:00 <sipa> as you can't do so at a reasonable speed anyway, it's probably better for everyone to not be reachable either
967 2012-05-18 19:31:32 <jgarzik> sipa: is there something special with the lowest level of scope, within a function or method, WRT LOCK()? I see at least three examples of: type MyFunc() { { LOCK(cs_foo); do something; } }
968 2012-05-18 19:31:37 <jgarzik> i.e. extra level of scope
969 2012-05-18 19:31:50 <jgarzik> LoadExternalBlockFile() does this, as do a few other places
970 2012-05-18 19:32:38 <sipa> jgarzik: that was simply to limit the code change necessary
971 2012-05-18 19:33:41 <sipa> when changing CRITICAL_BLOCK(cs) { ... } to { LOCK(cs); ... }
972 2012-05-18 19:34:03 <jgarzik> ok
973 2012-05-18 19:34:20 <sipa> if you modify code that involves such a double scope, feel free to improve it

985 2012-05-18 19:51:36 <nadrimajstor_> So far, so good. No internet hogging. For users with just few BTC in wallet, assume they are poor (with a terrible internet connection) and make -nolisten as default option.
986 2012-05-18 19:51:45 <nadrimajstor_> Just kidding. Thank you all for your time.

1038 2012-05-18 21:37:27 <Diapolo> I get that error very often ... never thought about what it means.
1039 2012-05-18 21:38:02 <luke-jr> wumpus: immediatley preceding the Reorg fail?
1040 2012-05-18 21:38:07 <jgarzik> you'll get that error, if your blockchain is not up-to-date
1041 2012-05-18 21:38:31 <wumpus> I can simply throw away the block chain and start over, but it's still kind of weird
1042 2012-05-18 21:38:53 <jgarzik> FetchInputs() is trying to connect today's transactions... but with a stuck blockchain, you will not have received those TX's dependents (probably)
1043 2012-05-18 21:40:00 <Diapolo> sipa: version message: version 60001, blocks=180662 but why is my client not using that number?

1049 2012-05-18 21:41:22 <Diapolo> wumpus: my client keeps DL'ing blocks from Sipas node, but shows no progressbar, because it reads the last checkpoint as block-count, although sipas node reports blocks=180662
1050 2012-05-18 21:41:35 <Diapolo> wumpus: sorry was not talking about your stuck issue
1051 2012-05-18 21:42:28 <wumpus> Diapolo: you need multiple outgoing connections before it trusts the total block count

1055 2012-05-18 21:43:06 <wumpus> this is a sanity measure, to prevent one node from lying and messing up the counts
1056 2012-05-18 21:43:16 <wumpus> normally that never happens anyway
1057 2012-05-18 21:43:24 <jgarzik> heh

1060 2012-05-18 21:43:55 <Diapolo> wumpus: playing aroung with IPv6, that's the cause ^^ any idea to get the progressbar back for such situations?
1061 2012-05-18 21:44:03 <wumpus> Diapolo: connect to more nodes

1073 2012-05-18 21:49:52 <wumpus> redownloading the block chain from scratch, I've saved the corrupted one in case someone someday wants to debug it
1074 2012-05-18 21:50:11 <luke-jr> wumpus: perhaps it should trust a single node's estimate provided it's reasonable? :p
1075 2012-05-18 21:50:14 <Diapolo> sipa: the first is a forced bound and the second one is "discovered" I guess speaking of [2002:5898:cc5b:0:8d15:c44e:90f3:45a5]
1076 2012-05-18 21:50:15 <sipa> wumpus: you can try to -loadblock= the old blk0001.dat
1077 2012-05-18 21:50:30 <sipa> Diapolo: yes, that's normal if it's discovered through different means
1078 2012-05-18 21:50:31 <luke-jr> wumpus: or at least increase the estimate by 1 for every 90 mins we're behind?

1082 2012-05-18 21:51:06 <wumpus> luke-jr: I suppose so, but that will make the judgement logic more complex, currently it's simply a median filter and that works well for all normal situations
1083 2012-05-18 21:51:23 <Diapolo> sipa: this does not harm the networking code that we habe a duplicate address in?

1089 2012-05-18 21:52:13 <jgarzik> grumble! 1) Fedora's rpm requires db4-utils, preventing use of libdb-utils to inspect db 5.x databases. 2) db_stat from libdb-utils, when force-installed, cannot see any data

1092 2012-05-18 21:52:56 <wumpus> gmaxwell: I don't remember it was stuck last time, then again, I run this one very sparsely, which is why it was two months behind
1093 2012-05-18 21:55:59 <gmaxwell> luke-jr: the values reported by peers should probably be clamped to HighestCheckpoint .. BestGuessBlock.Height+max(0,288*Day-BestGuessBlock.Day) ; where BestGuessBlock is either the highest checkpoint, or the best block if its over the highest checkpoint... then subject to the median filter, and a median of might then be reasonable to allow.

1103 2012-05-18 21:59:06 <sipa> delete your blockchain and redownload
1104 2012-05-18 21:59:18 <sipa> but since you were running 0.5.99, it's hard to say whether it was the result of buggy old code, a still-existing bug, or a harddisk corruption
1105 2012-05-18 21:59:23 <moa7> not gonna happen on my internet connection i'm afraid
1106 2012-05-18 22:00:05 <Eliel> moa7: then you might need to work on exporting the private keys to a light weight client and use that.
1107 2012-05-18 22:00:07 <sipa> if you're on git head, you can try deleting blkindex.dat and move blk0001.dat to blk0001.dat.old, and then run -loadblock=.../blkindex.dat.old

1109 2012-05-18 22:00:57 <Eliel> sipa: that functionality is not activated in the releases?
1110 2012-05-18 22:01:10 <wumpus> it wasn't merged yet
1111 2012-05-18 22:01:13 <sipa> Eliel: it will be, but there hasn't been a release since it was merged

1115 2012-05-18 22:01:53 <Eliel> which release is planned to activate multisig addresses on mainnet?
1116 2012-05-18 22:02:05 <sipa> 0.6.1, afaik
1117 2012-05-18 22:02:22 <kinlo> but it still isn't useable right?
1118 2012-05-18 22:02:45 <sipa> you can send to multisig addresses, and redeem if you have all necessary keys in one wallet
1119 2012-05-18 22:02:58 <Eliel> so, 0.6.2 supports it to some extent?
1120 2012-05-18 22:03:00 <kinlo> that defeats the purpose :)
1121 2012-05-18 22:03:29 <sipa> there just is no consensus/idea/implementation of how negotiation of multisig spendings must happen
1122 2012-05-18 22:03:31 pickett has joined

1124 2012-05-18 22:03:38 <moa7> i think "trust noone" is going to have to be dumped ...
1125 2012-05-18 22:03:42 <kinlo> ic

1128 2012-05-18 22:03:55 <kinlo> that was my followup question, how it was supposed to happen :p

1132 2012-05-18 22:04:32 <moa7> i can get a copy of a good blockchain from someone manually I guess?
1133 2012-05-18 22:04:47 <graingert_ecs> moa7: yes
1134 2012-05-18 22:04:57 <graingert_ecs> it would be handy to maintain a list of nodes that you control
1135 2012-05-18 22:05:02 <graingert_ecs> eg laptop desktop and phone
1136 2012-05-18 22:05:14 <sipa> moa7: that takes exactly as much network traffic as downloading it from the bitcoin network...
1137 2012-05-18 22:05:34 <graingert_ecs> sipa: but not storage space
1138 2012-05-18 22:05:38 <moa7> my test was to build everything myself and do all my own blockchain maintenance but I was vigilante enough about which version I was running ,...
1139 2012-05-18 22:05:41 <graingert_ecs> uses much less storage space
1140 2012-05-18 22:05:50 <sipa> graingert_ecs: huh?
1141 2012-05-18 22:05:50 <graingert_ecs> if you have one box which does all that
1142 2012-05-18 22:06:00 <graingert_ecs> and then other clients that trust that box
1143 2012-05-18 22:06:07 <graingert_ecs> I'd like to have that setup
1144 2012-05-18 22:06:15 <moa7> sipa : i mean met them and get file on USB stick, or similar
1145 2012-05-18 22:06:17 <graingert_ecs> eg I just have a box that sits under my desk
1146 2012-05-18 22:06:28 <sipa> moa7: try git head and use -loadblocks
1147 2012-05-18 22:06:33 <sipa> -loadblock i mean
1148 2012-05-18 22:06:39 <graingert_ecs> and then I have my phone and other machines run all the important tx by it
1149 2012-05-18 22:06:41 <moa7> sipa : more info
1150 2012-05-18 22:06:41 <moa7> ?
1151 2012-05-18 22:07:07 graingert_ecs has quit (Remote host closed the connection)
1152 2012-05-18 22:07:09 <sipa> moa7: -loadblock is a function to import a blockchain from a (potentially even corrupted) blk0001.dat file
1153 2012-05-18 22:07:16 <sipa> it's not in 0.6.2 yet though
1154 2012-05-18 22:07:25 <moa7> so it is CLI for bitcoind ?
1155 2012-05-18 22:07:34 <sipa> it's a command line option yes
1156 2012-05-18 22:07:41 <sipa> for bitcoind or bitcoin-qt
1157 2012-05-18 22:07:44 <moa7> could you paste the actual command?
1158 2012-05-18 22:07:56 ThomasV has joined
1159 2012-05-18 22:08:02 <sipa> which OS?
1160 2012-05-18 22:08:18 <moa7> "$./bitcoind -rescan -daemon -loadblock" ?
1161 2012-05-18 22:08:22 <moa7> linux
1162 2012-05-18 22:08:24 <Eliel> sipa: personally, I'd like an implementation that allows the user interface to be built so the user doesn't need to coordinate the communication at all.
1163 2012-05-18 22:08:41 <sipa> Eliel: not sure what you mean
1164 2012-05-18 22:09:34 <sipa> moa7: rm ~/.bitcoin/blkindex.dat; mv ~/.bitcoin/blk0001.dat ~/.bitcoin/blk0001.dat.old; ./bitcoind -daemon -loadblock=$HOME/.bitcoin/blk0001.dat.old
1165 2012-05-18 22:09:39 <wumpus> personally, I'd like a flying pony
1166 2012-05-18 22:09:54 <sipa> wumpus: with a spoiler
1167 2012-05-18 22:10:07 <sipa> don't forget about the spoiler
1168 2012-05-18 22:10:11 <Eliel> sipa: I mean that one of the keyholders prepares the transaction and hits "send" and as a result, the other keyholders get a message about it asking if they agree. All automatic, no need to coordinate it.
1169 2012-05-18 22:10:13 <wumpus> hehe

1172 2012-05-18 22:10:58 <Eliel> if enough of the others agree, the transaction is then broadcast.
1173 2012-05-18 22:10:58 <sipa> Eliel: very nice, but quite impossible without a third party doing coordination (who doesn't need any authority over the actual keys, though)
1174 2012-05-18 22:11:16 <sipa> but yes, that'd be perfect
1175 2012-05-18 22:11:26 <Eliel> sipa: the third party could be an auxiliary p2p network too
1176 2012-05-18 22:12:27 <sipa> or a DHT! *ducks*

1180 2012-05-18 22:13:43 <moa7> sipa : so when you say git head you mean build the alpha stuff again and use that?
1181 2012-05-18 22:13:50 <moa7> not git expert
1182 2012-05-18 22:14:23 <jgarzik> moa7: the block chain may be downloaded manually from http://eu1.bitcoincharts.com/blockchain/
1183 2012-05-18 22:14:27 <Eliel> sipa: good enough for this purpose I think :)
1184 2012-05-18 22:14:38 <sipa> moa7: yes
1185 2012-05-18 22:14:45 <sipa> kinlo: someone has to do it
1186 2012-05-18 22:14:58 <moa7> jgarzik : thnx but my internet would not cope as it is too large now ... :(
1187 2012-05-18 22:15:00 <Eliel> sipa: I mean, this auxiliary network could be called bitcoin wallet network :)
1188 2012-05-18 22:15:17 <sipa> Eliel: i see no reason to use another P2P network for this
1189 2012-05-18 22:15:23 <Eliel> sipa: while the current one is bitcoin node network
1190 2012-05-18 22:15:35 <kinlo> sipa: it would require more flexibility on the input transactions I guess
1191 2012-05-18 22:15:48 <moa7> jgarzik : also goes outside my trust noone test ...
1192 2012-05-18 22:15:51 <kinlo> sipa: you really need to be able to spend one particular transaction
1193 2012-05-18 22:16:13 <gmaxwell> sipa: The SpoilerPony should be made of Cake.
1194 2012-05-18 22:16:40 <Eliel> sipa: the wallet network would be mostly for communications between users.
1195 2012-05-18 22:16:56 <Eliel> not for transactions as such.
1196 2012-05-18 22:16:57 <sipa> Eliel: and do all users need to hear about all transactions?
1197 2012-05-18 22:17:02 <gmaxwell> kinlo: More flexiblity would be generally desirableâ but can you explain your use of the word _need_ there?
1198 2012-05-18 22:17:06 <sipa> Eliel: that's just not viable
1199 2012-05-18 22:17:21 <Eliel> of course not. All the net needs to do is help coordinate it in case both are not online
1200 2012-05-18 22:17:30 <Eliel> and if both are online, help them find each other
1201 2012-05-18 22:17:46 <sipa> Eliel: you mean TCP/IP?
1202 2012-05-18 22:18:06 <gmaxwell> Eliel: ... why do you think that belongs in bitcoin? It sounds like you're describing .. well, IP .. or at worse a gnutella or chat client.
1203 2012-05-18 22:18:13 <Eliel> sipa: IP addresses are not what I'd use to identify other wallets.

I'll need to select that, no?
1206 2012-05-18 22:19:46 TD has joined
1207 2012-05-18 22:20:05 <Eliel> gmaxwell: simply because I'm not aware of any other method that would be simultaneously both secure and simple to use for this sort of communication and the need as well as use case is there.
1208 2012-05-18 22:20:32 <Eliel> gmaxwell: but note, it'd be for wallets, not nodes.
1209 2012-05-18 22:20:39 <gmaxwell> kinlo: ah, you're talking about multisig, sorry I was out of sync. I expect all multisig spending will likely be (partially) manual.
1210 2012-05-18 22:21:12 <gmaxwell> Eliel: why are you imaging it would be secure by virtue of putting it inside the memory space of a process that handles high value private keys??
1211 2012-05-18 22:21:48 <gmaxwell> our current network protocol has basically no security featureâ because the blockchain consensus service doesn't really need any.
1212 2012-05-18 22:21:56 <gmaxwell> features*
1213 2012-05-18 22:22:42 <Eliel> gmaxwell: because it could use those keys for addressing and identification as well as verification.
1214 2012-05-18 22:22:57 <luke-jr> ugh, how do you merge .ui files? -.-
1215 2012-05-18 22:23:02 <gmaxwell> Thats really really super duper bad bad bad.
1216 2012-05-18 22:23:31 <Eliel> gmaxwell: why?
1217 2012-05-18 22:23:36 <gmaxwell> Eliel: You totally blow up bitcoin's anonymity by using addresses you spend to for general identification purposes.
1218 2012-05-18 22:24:21 <Eliel> gmaxwell: ... you're not imagining making it a social network are you?

1220 2012-05-18 22:24:41 <gmaxwell> Eliel: I scan the internet and make a map of Eliel nodes and ask them for their identity for example. Now I have a nice table of address ownership to IP addresses.
1221 2012-05-18 22:24:45 <wumpus> haha, like facebook, but for bitcoins!

1225 2012-05-18 22:26:09 <Eliel> gmaxwell: I was more thinking using the keys to identify source of messages and only to the recipient of the message.
1226 2012-05-18 22:26:12 <gmaxwell> in any case, go build what you want externally to bitcoin and solve all the hard problems and prove it can be usefully doneâ then argue to include it.
1227 2012-05-18 22:26:38 <sipa> gmaxwell: Pro
1228 2012-05-18 22:26:49 <gmaxwell> Eliel: I don't know of any protocol for doing that that lets you still route.
1229 2012-05-18 22:27:16 <sipa> gmaxwell: obviously, broadcast-to-all
1230 2012-05-18 22:27:25 danbri has joined
1231 2012-05-18 22:27:51 <Eliel> sipa: broadcast-to-all is too heavy. there'll be light nodes taking part.
1232 2012-05-18 22:28:00 <sipa> Eliel: and that's the problem :)
1233 2012-05-18 22:28:41 <gmaxwell> Eliel: I don't think you can have routing and blinding at the same time (or at least I don't know how), and without routing you could only flood which is clearly problematic.
1234 2012-05-18 22:29:14 <Eliel> ok, it's rather difficult :)
1235 2012-05-18 22:29:40 <gmaxwell> Maybe you could build some kind of flooding network based on using bitcoin mining as a POW to mitigate traffic. Who knows. But all we have at the moment is armwaving.
1236 2012-05-18 22:30:59 <gmaxwell> (e.g. nodes could agree to accept messages to flood if they come attached with a bitcoin blockshare of recent height of at least difficulty 0.1 which commits to the hash of the message in the coinbase)
1237 2012-05-18 22:31:35 <Diapolo> luke-jr: via text-editor :D
1238 2012-05-18 22:31:44 <jgarzik> moa7: there is no need to trust that blockchain
1239 2012-05-18 22:31:48 <jgarzik> moa7: bitcoin will validate it
1240 2012-05-18 22:31:50 <gmaxwell> But you can build all this with no direct bitcoin integration, just like p2pool requires no direct bitcoin integration. (and I wouldn't mind adding some extra rpc calls to extract any missing data it needed)
1241 2012-05-18 22:31:59 <jgarzik> moa7: -loadblock=/PATH/TO/blk0001.dat
1242 2012-05-18 22:32:10 <Eliel> it'd still not be scalable enough. This thing would pretty much need to be able to scale to billions of nodes
1243 2012-05-18 22:32:15 <wumpus> Diapolo: the annoying thing to merge are tablelayouts, because they contain explicit row/column numbers
1244 2012-05-18 22:32:30 <moa7> jgarzik : ok, i see thnx ... so i'd just need to get it delivered physically and then we're all good.
1245 2012-05-18 22:32:43 <wumpus> billions, even...
1246 2012-05-18 22:32:47 <gmaxwell> Eliel: well, then you need to go earn a fields medal first for your blinded but routable messaging ...
1247 2012-05-18 22:32:49 <jgarzik> blkhash.dat/txhash.dat/blkmeta.dat verified via network
1248 2012-05-18 22:32:54 <jgarzik> now running upgrade code
1249 2012-05-18 22:33:09 <moa7> my problem is i have enough bandwidth, etc resources to maintain a blockchain but not a full node
1250 2012-05-18 22:33:17 <jgarzik> LoadExternalBlockFile() works quite well
1251 2012-05-18 22:33:32 <moa7> and I dropped the ball keeping the right version because I didn't put enough time into git, etc
1252 2012-05-18 22:33:34 <Diapolo> wumpus: forget the last thing with the frame, but I feel really more comfortable with adding code via XML-edit, than via the Qt Designer sometimes.
1253 2012-05-18 22:33:36 <gmaxwell> moa7: Can you restate you problem? That didn't make sense to me.
1254 2012-05-18 22:33:54 <moa7> gmaxwell : which part?
1255 2012-05-18 22:34:08 <gmaxwell> moa7: "i have enough bandwidth, etc resources to maintain a blockchain but not a full node"
1256 2012-05-18 22:34:13 <wumpus> Diapolo: yes, especially when moving widgets it's sometimes easier to do by hand.. do check the result in the editor though :-)
1257 2012-05-18 22:34:21 <moa7> i have a limited internet connection
1258 2012-05-18 22:34:26 <gmaxwell> I don't know what you mean by 'a blockchain but not a full node'
1259 2012-05-18 22:34:31 <gmaxwell> moa7: sure. and?
1260 2012-05-18 22:34:44 <gmaxwell> The maximum long term rate for the blockchain at the moment is about 14kbit/sec.
1261 2012-05-18 22:34:44 <moa7> so i can upload the latest blocks every 3-4 days or so ..
1262 2012-05-18 22:34:56 <gmaxwell> the actual rate is more like 2kbit/sec.
1263 2012-05-18 22:34:59 * TheSeven has that issue the other way round... lots of bandwidth but no space for a blockchain on some mobile devices
1264 2012-05-18 22:35:06 <moa7> but i can't leave a client running all the time broadcasting everyone elses transactions
1265 2012-05-18 22:35:17 <gmaxwell> Just set -listen=0 and -maxconnections=1
1266 2012-05-18 22:35:28 <moa7> but when my blckchain got too far behind it got corrupted
1267 2012-05-18 22:35:49 <gmaxwell> moa7: thats not because it was too far behind.
1268 2012-05-18 22:36:00 <Eliel> gmaxwell: hmm... something tor based might work... I'm just not too hot on having to bring tor in as a luggage for it to work :P
1269 2012-05-18 22:36:01 <Diapolo> wumpus: I found out about a nice option in the Designer, dunno what's it called in english but it resides under Layout -> the last one (easen layout or sth.)

1275 2012-05-18 22:36:39 <moa7> in the end it is about how amny resources one needs to put into it
1276 2012-05-18 22:36:45 <gmaxwell> moa7: in any case if you leave it running with -listen=0 and -maxconnections=1 it will use a trivial amount of bandwidth.
1277 2012-05-18 22:36:53 <Diapolo> wumpus: an auto-cleanup for too complex layouts ... which is not beneficial to us currently, but it's nice to know
1278 2012-05-18 22:37:20 <sipa> kinlo: use validateaddress
1279 2012-05-18 22:37:25 <kinlo> right
1280 2012-05-18 22:37:26 <sipa> kinlo: that reveals public keys as well
1281 2012-05-18 22:37:27 <moa7> gmaxwell : that's a good idea .. never seen that -listen=0 ... link on more info, thnx?
1282 2012-05-18 22:37:34 <kinlo> oh I forgot, you already said that
1283 2012-05-18 22:37:37 <kinlo> sorry :p
1284 2012-05-18 22:37:40 <Diapolo> wumpus: I see it could be used on askpassphrasedialog.ui
1285 2012-05-18 22:38:20 <moa7> gmaxwell: also do you have a trusted node you could recommend for the one connection?
1286 2012-05-18 22:38:41 <gmaxwell> moa7: listen=0 just doesn't allow incoming connections. It's in the help output.
1287 2012-05-18 22:38:54 <moa7> wiki page?
1288 2012-05-18 22:39:10 <moa7> help output is kind of sparse
1289 2012-05-18 22:39:16 <wumpus> Diapolo: thanks, didn't know about that option. I've never had the too complex layout problem yet, though.
1290 2012-05-18 22:39:41 <gmaxwell> moa7: you don't /really/ need a trusted nodeâ at least so long as you're paying attention to your usage and would notice yourself falling behind on the blockchain. The security of bitcoin doesn't depend on your peers being honest to you.
1291 2012-05-18 22:40:18 <Diapolo> wumpus: seems to reindex the rows in askpassphrasedialog.ui when run
1292 2012-05-18 22:40:20 <moa7> "The security of bitcoin doesn't depend on your peers being honest to you." ... is this completely correct?
1293 2012-05-18 22:40:27 <moa7> not how I understood it
1294 2012-05-18 22:40:46 <BlueMatt> can someone check if 2001:470:9ff2:2:a001:3cff:fea5:a49 is up and accepting bitcoin p2p connections?
1295 2012-05-18 22:40:47 <moa7> if you are surrounded by dishoest peers is not a good thing I thought?
1296 2012-05-18 22:41:24 <gmaxwell> moa7: they can DOS attack you, of course. But unless they have enormous amounts of hasing power they can't fake you out in any obvious way.

1299 2012-05-18 22:42:08 <gmaxwell> If they could bitcoin would be over. EvilMcHacker would use a botnet to start 1,000,000 'nodes' (really just proxies to a single malicious node) and most everyone would only be connected to him.

1304 2012-05-18 22:43:45 <BlueMatt> Diapolo: whats the result?
1305 2012-05-18 22:44:01 <gmaxwell> (or alterantively, check that your best block matches the one on the explorer sites or gribble)
1306 2012-05-18 22:44:08 <jgarzik> gmaxwell sipa: DB_TXN_BULK looks worth investigating http://docs.oracle.com/cd/E17076_02/html/api_reference/C/txnbegin.html
1307 2012-05-18 22:44:24 <jgarzik> we gotta be able to speed up block indexing

1310 2012-05-18 22:44:35 <Diapolo> tried with -addnode and with -connect
1311 2012-05-18 22:44:49 <moa7> gmaxwell: thnx .. i guess maxconnection=1 is somewhat similar to a light client trusting a server?

1315 2012-05-18 22:45:09 <Diapolo> BlueMatt: I know my IPv6 is working for connection to nodes, as I checked with sipas node earlier today.
1316 2012-05-18 22:45:13 <gmaxwell> moa7: no, becuase you're fully validating the bitcoin protocol rules.
1317 2012-05-18 22:45:18 <gmaxwell> It's more secure than that.
1318 2012-05-18 22:45:24 <BlueMatt> yea I probably have a DROP somewhere bad in iptables
1319 2012-05-18 22:45:29 <moa7> yeah
1320 2012-05-18 22:45:29 <BlueMatt> s/ip/ip6/
1321 2012-05-18 22:45:59 <sipa> moa7: no, a light client cannot verify the blocks it sees coming in
1322 2012-05-18 22:46:13 <gmaxwell> moa7: the risk is only that your peer my DOS you, or if he has a bunch of mining power he could create a fork for you (costing himself hundreds of btc in processing in the process).
1323 2012-05-18 22:46:14 <moa7> so "-loadblock" is verifying all the blocks again from 6000?
1324 2012-05-18 22:46:26 <BlueMatt> Diapolo: can you try again?
1325 2012-05-18 22:46:30 <Diapolo> sure
1326 2012-05-18 22:46:59 <gmaxwell> the more pratical issue is that your one peer may be just broken accidentally... and you'll end up behind.. but thats better than being turned off.
1327 2012-05-18 22:47:44 <moa7> i'm just trying to make sure bitcoi can work for semi-tech-literate (dumbasses) before I sink serious coinage into it ....
1328 2012-05-18 22:47:50 <Diapolo> BlueMatt: nope ... IP is correct? -addnode=[2001:470:9ff2:2:a001:3cff:fea5:a49]

1342 2012-05-18 22:51:24 <moa7> spent a lot of time on key security but keeping a good blockchain is not trivial i'm discovering
1343 2012-05-18 22:51:30 <BlueMatt> yay! we now have working ipv6 dnsseeds
1344 2012-05-18 22:51:41 <gmaxwell> moa7: It is trivial, thousands of users do it with no issues.
1345 2012-05-18 22:51:45 <Diapolo> blocks=95265 :)?
1346 2012-05-18 22:51:47 <gmaxwell> moa7: Then don't run git. Run release versions.
1347 2012-05-18 22:51:52 <BlueMatt> yea, its still syncing
1348 2012-05-18 22:52:00 <BlueMatt> we have working ipv6 seednodes, just not synced ones...yet
1349 2012-05-18 22:52:35 <Diapolo> would this one relay my address too? well my incomming connections don't work yet ... so I guess no
1350 2012-05-18 22:53:21 <jgarzik> really, for initial block download, we should stuff a -ton- of database i/o into a single transaction
1351 2012-05-18 22:53:27 <jgarzik> but that's a PITA, code wise
1352 2012-05-18 22:53:49 <jgarzik> one transaction per 500 blocks, say
1353 2012-05-18 22:53:59 <BlueMatt> you would need, say, some kind of buffer of blocks
1354 2012-05-18 22:54:02 <BlueMatt> ;)

1363 2012-05-18 22:54:51 <BlueMatt> well, its easier if you know you have more blocks coming in right afterwards

1365 2012-05-18 22:55:08 <BlueMatt> ie you could commit when you have an empty buffer
1366 2012-05-18 22:55:38 <jgarzik> well, the optimization is pointless if !IsInitialBlockDownload()
1367 2012-05-18 22:55:39 <sipa> BlueMatt: not for now; we need commit/rollback per block, as the block connection mechanism depends on it
1368 2012-05-18 22:55:48 <jgarzik> yes
1369 2012-05-18 22:55:54 <jgarzik> this is not for livenet
1370 2012-05-18 22:56:54 <BlueMatt> sipa: yea, I was mostly just joking, but its a neat optimization to add
1371 2012-05-18 22:57:05 <BlueMatt> and helps the coding, a tiny bit
1372 2012-05-18 22:57:44 <jgarzik> even with DB_TXN_NOSYNC, -something- inside bdb is doing a bunch of fsync

1378 2012-05-18 23:00:53 <Diapolo> did anyone do some tests with: dbenv.set_flags(DB_REGION_INIT, 1); perhaps it helps a little I know I talked to sipa and he thought it would not be beneficial
1379 2012-05-18 23:01:05 <gribble> New news from bitcoinrss: sipa opened pull request 1357 on bitcoin/bitcoin <https://github.com/bitcoin/bitcoin/pull/1357>

1381 2012-05-18 23:01:17 <gmaxwell> moa7: you can tell it maxconnections=1 and it will automatically run one. I wouldn't pick a single node because if it moves or goes down you'll break.
1382 2012-05-18 23:01:36 <moa7> so just whatver it picks?

1386 2012-05-18 23:02:23 <sipa> you can use -addnode, which will try to keep a connection to one node, but use the normal mechanism as well
1387 2012-05-18 23:02:26 <moa7> it is thrashing the harddrive so that's another thing to keep in mind ...
1388 2012-05-18 23:02:32 <Diapolo> sipa: if jgarzik is doing benches or BDB debugging currently perhaps he wants to take a look at it, too :)
1389 2012-05-18 23:02:56 <jgarzik> sipa: I'm surprised CPubKey does not simply inherit from vector<unsigned char> as several other bitcoin classes do
1390 2012-05-18 23:03:13 <sipa> jgarzik: i believe i started out that way, but changed it for some reason
1391 2012-05-18 23:03:53 <moa7> sipa : yeah, i use addnode with some addresses that were once called "fallback nodes" ... which one of those is the best ... or another one maybe?
1392 2012-05-18 23:04:30 <jgarzik> sipa: I see constructions like pubkey.vchPubKey.size(), which seems like it should be pubkey.size()
1393 2012-05-18 23:04:41 <jgarzik> if its public, might as well inherit
1394 2012-05-18 23:04:58 <sipa> jgarzik: where do you see that?
1395 2012-05-18 23:05:18 <jgarzik> sipa: key.h
1396 2012-05-18 23:05:40 <sipa> jgarzik: CKey is friend of CPubKey
1397 2012-05-18 23:06:02 <sipa> vchPubKey is not public, and very intentionally (i tried to do without .Raw() as well, but that proved too hard)

1433 2012-05-18 23:23:47 <sipa> well, my best guess right now is that it resulted from running broken code
1434 2012-05-18 23:23:48 <moa7> if you do this and this and that i can guarantee you will corrupt your blockchain

1445 2012-05-18 23:29:30 <jgarzik> also motivates work on pruning...

1447 2012-05-18 23:30:04 <moa7> at which point will satoshidice prompt more fees from miners is what I'm interested in ...
1448 2012-05-18 23:30:07 <gmaxwell> sipa: you shouldn't end up with a corrupted chain with power failures.
1449 2012-05-18 23:30:17 <sipa> gmaxwell: indeed, i wish that was true...
1450 2012-05-18 23:31:20 <moa7> sipa : yeah, it may have been a disk error ... or the old RC code ... but it is worth the time to reproduce it is what I'm saying
1451 2012-05-18 23:31:32 <gmaxwell> sipa: it's pretty easy to snapshot block devices at random points to test that sort of thing.. .. sync a node taking snapshots every few seconds, then checkblocks a node started on each snapshot. on fail .. automatically email all the data to all the bdb developers? :)
1452 2012-05-18 23:31:53 <sipa> haha
1453 2012-05-18 23:32:22 <sipa> moa7: if it is neither a disk error or the result of using pre-RC code: yes
1454 2012-05-18 23:33:02 <moa7> ok so loadblock will reveal all ...
1455 2012-05-18 23:33:25 <sipa> ?
1456 2012-05-18 23:33:50 <sipa> is loadblock still running?
1457 2012-05-18 23:34:00 <moa7> yep ... 141000ish
1458 2012-05-18 23:34:27 <moa7> it's reverifying the cahin using git head right?
1459 2012-05-18 23:34:34 <moa7> s/cahin/chain
1460 2012-05-18 23:34:43 <sipa> if you built from git head, yes
1461 2012-05-18 23:34:48 <moa7> yes
1462 2012-05-18 23:35:04 <sipa> can you paste a few line from what's being added to debug.log?
1463 2012-05-18 23:35:12 <moa7> sure
1464 2012-05-18 23:35:16 <sipa> tail ~/.bitcoin/debug.log
1465 2012-05-18 23:35:22 <moa7> ProcessBlock: ACCEPTED SetBestChain: new best=000000000000043713cc height=141695 work=86420695855664177568 ProcessBlock: ACCEPTED SetBestChain: new best=00000000000007ccf2e8 height=141696 work=86428451400042204976 ProcessBlock: ACCEPTED SetBestChain: new best=00000000000008f2069d height=141697 work=86436206944420232384 ProcessBlock: ACCEPTED SetBestChain: new best=000000000000011f76b7 height=141698 work=86443962488798259792
1466 2012-05-18 23:35:29 <sipa> ok
1467 2012-05-18 23:35:40 <sipa> good
1468 2012-05-18 23:35:53 <moa7> good
1469 2012-05-18 23:36:09 <sipa> but using loadblock will not reveal what caused your corruption
1470 2012-05-18 23:36:38 <moa7> no but if it is still corrupted it will reveal a problem
1471 2012-05-18 23:36:48 <sipa> It won't be :)
1472 2012-05-18 23:37:05 <moa7> i'll hold off on the bug report then
1473 2012-05-18 23:38:15 <moa7> would be good if git appended a version number to the executable filename
1474 2012-05-18 23:38:38 <sipa> it's logged in debug.log
1475 2012-05-18 23:39:04 <moa7> yeah but I want to see what the file is by "ls"
1476 2012-05-18 23:39:17 <moa7> before it runs
1477 2012-05-18 23:40:10 <sipa> make -f makefile bitcoind && mv bitcoind bitcoind-$(git describe)
1478 2012-05-18 23:42:44 <moa7> thnx ... you are building me a custom script as I copy these
1479 2012-05-18 23:43:11 <sipa> makefile.unix instead of makefile
1480 2012-05-18 23:43:59 barmstrong has quit (Remote host closed the connection)
1481 2012-05-18 23:44:56 <moa7> yeah
1482 2012-05-18 23:45:17 barmstrong has joined
1483 2012-05-18 23:45:44 <moa7> and for bitcoin-qt ... ?
1484 2012-05-18 23:46:36 <sipa> qmake && make && mv bitcoin-qt bitcoin-qt-$(git describe)
1485 2012-05-18 23:46:52 <moa7> right thnx
1486 2012-05-18 23:48:41 <moa7> to be frank I gave up following dev work closely around time of bitcoin-qt split ...
1487 2012-05-18 23:49:31 <moa7> invested fair amount of time getting bitcoin-wxwidgets to build on different platforms ...
1488 2012-05-18 23:49:57 <moa7> hence the sloppy version following
1489 2012-05-18 23:51:06 <moa7> maybe the price was dropping around them too ??
1490 2012-05-18 23:52:15 <moa7> is anybody still keeping a wxwidgets bitcoin gui up to date?
