2 2013-04-29 00:00:19 <travolta> but how the random keys are generated I'm worried if there it a programatic way to guess them
3 2013-04-29 00:00:26 <travolta> based on the seed generation technique
4 2013-04-29 00:00:54 <sipa> bitcoind uses a cryptographic PRNG (from OpenSSL) to generate keys
5 2013-04-29 00:01:01 <Wayward> so have there been any serious attempts at attacking bitcoin addresses with ASIC pools?
6 2013-04-29 00:01:17 <Wayward> eg, those addresses with 11,111 btc in them
7 2013-04-29 00:01:17 <travolta> thats a silly question...
8 2013-04-29 00:01:26 <Luke-Jr> Wayward: you can't attack bitcoin addresses
9 2013-04-29 00:01:41 <sipa> Wayward: you think someone built 1) an ASIC for bitcoin address generation 2) built a pool out it?
10 2013-04-29 00:01:45 <Wayward> Luke-Jr, if not, then why do people in #bitcoin-dev continously spout that reusing a bitcoin address weakens its security
11 2013-04-29 00:01:52 <travolta> only way to attack bitcoin address is if you knew the seed mechanism that was used to create them and if they had a fundamental flaw in its entropy
12 2013-04-29 00:01:55 <sipa> Wayward: that has nothing to do with that
13 2013-04-29 00:02:06 <sipa> Wayward: reusing addresses is just bad for privacy of the network
14 2013-04-29 00:02:07 <travolta> which at the question I asked about a particular private key generation
15 2013-04-29 00:02:28 <Wayward> sipa: apparently also unwrapping bitcoins with the same address over and over causes crypto weakness
16 2013-04-29 00:02:40 <sipa> 'unwrapping' wut?

21 2013-04-29 00:03:22 <sipa> travolta: yes
22 2013-04-29 00:03:28 <Luke-Jr> Wayward: because multiple signatures can, in some cases (not used today), expose the private key
23 2013-04-29 00:03:37 <Luke-Jr> Wayward: and it harms the network's privacy attributes
24 2013-04-29 00:03:39 <sipa> travolta: though some addresses are generated from a password ("brainwallets"), which is way more vulnerable
25 2013-04-29 00:04:19 johnsoft has joined
26 2013-04-29 00:04:34 <sipa> Luke-Jr: what cases are you talking about?
27 2013-04-29 00:04:36 <Wayward> Luke-Jr: a single signature wouldn't give -any- advantage?
28 2013-04-29 00:04:47 <Wayward> even the smallest of
29 2013-04-29 00:04:51 <travolta> still worries like hell about using a know entropy generating mechanism
30 2013-04-29 00:04:59 <Luke-Jr> sipa: Lamport
31 2013-04-29 00:05:00 <sipa> travolta: ??
32 2013-04-29 00:05:05 <travolta> I think thats a recipe for disaster
33 2013-04-29 00:05:05 <sipa> Luke-Jr: oh, right o
34 2013-04-29 00:05:12 <gmaxwell> sipa: he means that reusing signatures breaks our ability to adopt lamport if ecdsa turns out to be weak.
35 2013-04-29 00:05:15 <sipa> travolta: elaborate
36 2013-04-29 00:05:16 <travolta> you know if you get a well known private key generating tool
37 2013-04-29 00:05:24 <travolta> one of the popular ones
38 2013-04-29 00:05:42 <sipa> no idea what you mean
39 2013-04-29 00:05:51 <travolta> if your not using some quantum hardware number generator isnt its entropy in essense "weak"
40 2013-04-29 00:06:02 <travolta> to make private addresses

42 2013-04-29 00:06:26 <Luke-Jr> travolta: most PCs these days have onboard RNG chips
43 2013-04-29 00:06:38 <sipa> and even those that don't generate more than enough entropy by other means
44 2013-04-29 00:06:45 <sipa> (interrupt timings, ...)
45 2013-04-29 00:06:54 <monda7> I'm reading that non standard scripts are not transmitted. Why use a scripting system?
46 2013-04-29 00:07:20 <sipa> monda7: because Satoshi said "there shall be scripts!"
47 2013-04-29 00:07:44 <travolta> Satoshi isnt real though
48 2013-04-29 00:07:45 <travolta> lo
49 2013-04-29 00:07:48 <travolta> he is fictional
50 2013-04-29 00:07:51 <sipa> maybe
51 2013-04-29 00:07:54 <monda7> sipa: how do you know if a script is 'standard'?
52 2013-04-29 00:08:16 <Luke-Jr> monda7: Bitcoin uses a scripting system so that clients can add future features while remaining backward compatible
53 2013-04-29 00:08:17 <sipa> monda7: when it matches one of the standard script patterns
54 2013-04-29 00:08:38 <sipa> and yes, making something go from nonstandard to standard is much easier than introducing new script types
55 2013-04-29 00:09:17 <monda7> Luke-Jr: could you give me an example?
56 2013-04-29 00:09:22 wei_ has joined
57 2013-04-29 00:09:31 <monda7> how would you make something go from nonstandard to standard?
58 2013-04-29 00:09:43 <monda7> any of you guys going to the san jose conference?
59 2013-04-29 00:10:20 <sipa> yes
60 2013-04-29 00:10:20 <Luke-Jr> monda7: the old version 0 addresses represent a script: OP_DUP OP_HASH160 OP_EQUALVERIFY OP_CHECKSIG
61 2013-04-29 00:10:47 <Luke-Jr> monda7: "nonstandard" just means "Bitcoin-Qt won't relay it on p2p"
62 2013-04-29 00:10:58 <Luke-Jr> oops
63 2013-04-29 00:11:04 <Luke-Jr> monda7: the old version 0 addresses represent a script: OP_DUP OP_HASH160 <pubkeyhash> OP_EQUALVERIFY OP_CHECKSIG
64 2013-04-29 00:11:08 <sipa> yeah :)

67 2013-04-29 00:12:06 <Luke-Jr> monda7: newer version 5 addresses (p2sh) are a special "magic" template: OP_HASH160 <scripthash> OP_EQUALVERIFY
68 2013-04-29 00:12:14 <Luke-Jr> err
69 2013-04-29 00:12:16 <Luke-Jr> OP_EQUAL there
70 2013-04-29 00:12:22 <monda7> why not just enumerate the standard scripts and embed that single number in the transactions?
71 2013-04-29 00:12:41 <travolta> I just reliazed something sipa, its probably best to keep multiple wallets right?
72 2013-04-29 00:12:43 <sipa> monda7: that wouldn't allow added more in the future
73 2013-04-29 00:12:53 <travolta> if your dealing with like 10,000+ keys
74 2013-04-29 00:12:59 <sipa> travolta: probably, yes
75 2013-04-29 00:13:05 <monda7> new clients could define a new script number 8 which they all agree means
76 2013-04-29 00:13:13 <sipa> monda7: that would require a hard fork
77 2013-04-29 00:13:14 <monda7> new clients could define a new script number 8 which they all agree means <code>
78 2013-04-29 00:13:26 <sipa> as every node needs to be able to verify every transaction
79 2013-04-29 00:13:29 <sipa> in every block
80 2013-04-29 00:13:38 <monda7> ok
81 2013-04-29 00:13:46 <sipa> so adding a new script type would require every single client to be updated
82 2013-04-29 00:13:53 santoscork_ has joined
83 2013-04-29 00:13:58 <sipa> and all those that don't risk ending up on a fork of the chain
84 2013-04-29 00:14:13 <sipa> the bitcoin validation rules are really as strict as they can be
85 2013-04-29 00:14:23 <monda7> i see so, even if a client doesn't relay the transaction, if it disagrees with the other clients about how its verified, it creates a fork
86 2013-04-29 00:14:33 <amantonop> the scripts are both the best feature and the most flexible part of bitcoin, I love them!
87 2013-04-29 00:14:54 <sipa> well, i think the design of the script language is really sloppy and handwavy
88 2013-04-29 00:15:02 <amantonop> they are not Turing complete are they?
89 2013-04-29 00:15:02 <monda7> so validation matters for more then mining?
90 2013-04-29 00:15:10 <sipa> monda7: absolutely
91 2013-04-29 00:15:12 <monda7> amantonop: they are not
92 2013-04-29 00:15:23 <sipa> monda7: validation is how nodes make sure miners don't cheat!
93 2013-04-29 00:15:27 <amantonop> so theoretically, they could be implemented in a deterministic and computable state machine
94 2013-04-29 00:15:35 <sipa> sure

99 2013-04-29 00:15:59 <sipa> monda7: fork
100 2013-04-29 00:16:09 <sipa> well, in the worst case

103 2013-04-29 00:16:41 <sipa> if one part of the network uses strictly stronger rules (i.e., everything that the others reject, they reject too, and more)
104 2013-04-29 00:16:52 <sipa> and the stronger rules are enforced by a majority of miners

107 2013-04-29 00:17:05 <sipa> then no fork can remain
108 2013-04-29 00:17:32 <sipa> in every other case, you get a permanent fork

112 2013-04-29 00:18:32 <amantonop> sipa: would it be accurate to say that minority forks are harmless? That it only matters if a substantial minority forks, causing two well-balanced islands (like what happened with the 0.7.1). If it is just a handful, they will eventually be forced to change software or they're on the useless blockchain?
113 2013-04-29 00:18:42 <monda7> so scripting allows you to roll out more features that are verified by the older clients
114 2013-04-29 00:18:50 <monda7> even though the older clients wont relay the transaction
115 2013-04-29 00:18:51 <sipa> amantonop: all depends on how economically meaningful they are

120 2013-04-29 00:19:05 <sipa> adding such a strictly stronger set of rules is called a "soft forking change"
121 2013-04-29 00:19:10 <Luke-Jr> something happened with 0.7.1?
122 2013-04-29 00:19:28 <sipa> i assume he means 0.7.x vs 0.8.0
123 2013-04-29 00:19:30 <amantonop> Luke-Jr: sorry perhaps I quoted the wrong version
124 2013-04-29 00:19:33 <Wayward> I have a very simple question about scripts. Is it possible to write a script in a transaction that would make it appear that someone sent you coins, but when you goto spend them you find that it's not possible? Eg, signing with two keys, or with one key that doesn't even belong to you?
125 2013-04-29 00:19:38 <amantonop> I mean the BDB bug fork
126 2013-04-29 00:19:47 <sipa> Wayward: no
127 2013-04-29 00:20:00 <Wayward> sipa: if no, then why not?
128 2013-04-29 00:20:07 <sipa> Wayward: scripts evaluate to either true of false, and this does not change over time
129 2013-04-29 00:20:20 <Wayward> great, true or false
130 2013-04-29 00:20:27 <Wayward> but you can still sign coins with multiple keys
131 2013-04-29 00:20:34 <sipa> yes
132 2013-04-29 00:20:37 <Wayward> assuming the receiver doesn't have both keys
133 2013-04-29 00:20:41 <Wayward> how do they spend their coin?
134 2013-04-29 00:20:46 <sipa> wait
135 2013-04-29 00:20:48 <Luke-Jr> amantonop: that was 0.8.0 breaking compat with everything else
136 2013-04-29 00:20:50 <Wayward> and assuming bitcoin-qt doesn't anticipate this
137 2013-04-29 00:21:02 <sipa> if you want to do with, you create an output that is a script requiring two keys
138 2013-04-29 00:21:11 <Wayward> or a script that mtgox doesn't know how to handle
139 2013-04-29 00:21:20 <sipa> Wayward: the script is determined by the receiver
140 2013-04-29 00:21:27 <amantonop> Luke-Jr: right, that's what I meant
141 2013-04-29 00:21:29 <sipa> an address is a shorthand for a particular script
142 2013-04-29 00:21:29 <Wayward> the script is determined by the sender
143 2013-04-29 00:21:42 <sipa> the sender puts the script in the transaction
144 2013-04-29 00:21:44 <Wayward> sipa: i send you bitcoins, i tell you how you can spend them
145 2013-04-29 00:21:53 <sipa> but the receiver decides where to send them
146 2013-04-29 00:21:57 <Wayward> yes
147 2013-04-29 00:22:07 <Wayward> but i tell you what forms of identification you need to spend them
148 2013-04-29 00:22:12 <sipa> Wayward: that's like saying "hi, i sent you a letter, to addres 42 wallaby way, sydney"
149 2013-04-29 00:22:19 <sipa> Wayward: that's ridiculous
150 2013-04-29 00:22:30 <sipa> the receiver tells you the address at which he accepts transactions
151 2013-04-29 00:22:42 <Wayward> ok
152 2013-04-29 00:22:51 <sipa> if you send coins somewhere else, well, you're stupid
153 2013-04-29 00:23:05 <Wayward> so how can the same coin be signed to two receivers?
154 2013-04-29 00:23:13 <Wayward> it's possible via script
155 2013-04-29 00:23:15 <sipa> yes
156 2013-04-29 00:23:16 <Wayward> allowed even
157 2013-04-29 00:23:25 <Wayward> but if both people don't know each other
158 2013-04-29 00:23:30 <sipa> they jointly decide a script that will require them both to sign
159 2013-04-29 00:23:31 <Wayward> both clients show they have coin to spend but can't spend it
160 2013-04-29 00:23:35 <sipa> no
161 2013-04-29 00:23:44 <sipa> clients don't do that, unless they own both keys
162 2013-04-29 00:23:53 <Wayward> have we tested this
163 2013-04-29 00:23:56 <sipa> yes
164 2013-04-29 00:24:09 <sipa> if you want to deal with complex scripts, you'll need custom software anyway
165 2013-04-29 00:24:18 <Wayward> well, yes
166 2013-04-29 00:24:21 <Wayward> but so does the receiver
167 2013-04-29 00:24:23 <monda7> so what scripts are standard. is there a list somewhere?
168 2013-04-29 00:24:25 <sipa> but the important part is that despite that, every client out there can send to a multisig address
169 2013-04-29 00:24:38 <sipa> even without knowing the script involved

479 2013-04-29 04:14:49 <rfish> And another question is what incentive do miners have in propigating transactions throughout the network
480 2013-04-29 04:15:04 <sivu> fees
481 2013-04-29 04:15:16 <rfish> no, that is for including them in the next block
482 2013-04-29 04:15:21 <Luke-Jr> fees, and also a healthy network means Bitcoins have value

496 2013-04-29 04:17:09 <Luke-Jr> there are two things:
497 2013-04-29 04:17:31 <Luke-Jr> 1) relaying transactions p2p; all nodes (not miners) must do this for the network to function; the incentive is to keep the network functioning so their own bitcoins have value
498 2013-04-29 04:17:45 <Luke-Jr> 2) including transactions in blocks; only miners do this, and they get the transaction fees for doing it

500 2013-04-29 04:18:59 <rfish> ok, most people don't care about that, they just assume other people will do it
501 2013-04-29 04:19:03 <rfish> take torrents for example
502 2013-04-29 04:19:15 <rfish> people choose not to upload
503 2013-04-29 04:19:20 <rfish> and to only download
504 2013-04-29 04:19:38 <rfish> and when it is required there are ways to upload to yourself to fake out the system
505 2013-04-29 04:21:49 <rfish> I'm sure someone will create a wallet that claims to comsume less bandwidth and it could catch on

574 2013-04-29 05:54:13 <dansmith_btc> jgarzik, and the transactions as well
575 2013-04-29 05:54:14 <jgarzik> dansmith_btc: unspent transactions are 'gettransaction', otherwise you will need to get down-n-dirty with the raw block serialization
576 2013-04-29 05:54:20 <jgarzik> or gettxout
577 2013-04-29 05:54:54 <Luke-Jr> or txindex=1 <.<

684 2013-04-29 08:32:07 <weex> the other thing you can do is make sure the output of the transaction that went to you is used as an input to the payment that sends to another address

687 2013-04-29 08:32:23 <weex> because the whole reason for waiting for confirmations is to protect yourself against double spending
688 2013-04-29 08:32:43 <weex> the risk is higher the fewer confirmations you wait for
689 2013-04-29 08:34:00 <jojo_> ok but if i have a database that keeps track of all the coins will that work to or should i still wait for the confirmationes?

Just curious cus all the attacks seems to be done by being the biggest hascher in the world. Am i right or am totally of now? :)

702 2013-04-29 08:52:12 <jojo_> on 0 conf it could be a bit unsecure either way right?
703 2013-04-29 08:52:50 <jojo_> Just asking cus im curios now.
704 2013-04-29 08:52:56 <weex> a higher network hashrate makes it harder to do an attack if you don't have an asic
705 2013-04-29 08:53:05 <weex> even if you do have asics

707 2013-04-29 08:53:45 <weex> the defense for 0 confirmation is not to accept incoming connections and try to connect to well connected nodes
708 2013-04-29 08:54:41 <jojo_> As i read there are about 47000 orders on bitforce and that hashrate should be pretty hard to get 10% of right?

712 2013-04-29 08:56:09 <weex> it's 70th now? so 7th is yeah...pretty hard to get
713 2013-04-29 08:57:02 <weex> by default a node will connect with just about any other node but you can set a config variable to disallow connections from other than a certain set of nodes

774 2013-04-29 09:58:12 <Diablo-D3> now ask why put

779 2013-04-29 09:59:18 <syskk> in which object are private keys stored?
780 2013-04-29 09:59:20 <sipa> travolta: labels and accounts are implementation-wise the same (which just makes it even more confusing), but labels are just for recognizing addresses in your address book, and useful even if you don't use the accounting system

823 2013-04-29 10:24:06 <sipa> jgarzik: there are several problems with getblock/getransaction/getrawtransaction imho
824 2013-04-29 10:24:28 <jgarzik> sipa: the main use case was mentioned earlier on IRC: watching for new blocks, and scanning their entirety yourself
825 2013-04-29 10:25:08 <sipa> there's no reason why you can't even get parsed raw transactions from the chain, even without txindex
826 2013-04-29 10:25:37 <sipa> and there should be an equivalent to getrawtransaction, but fetching from wallet instead of mempool/chain
827 2013-04-29 10:25:44 <jgarzik> sipa: except the lack of an RPC interface permitting one to do so, that is :)
828 2013-04-29 10:25:50 <sipa> yes, indeed
829 2013-04-29 10:26:06 <jgm> getrawblock would definitely be handy
830 2013-04-29 10:26:08 <buZz> does this still work? https://github.com/sacarlson/MultiCoin
831 2013-04-29 10:26:10 <sipa> there is a pullreq to add a block hash to getrawtransaction
832 2013-04-29 10:26:23 <sipa> which would work, but is still a hack
833 2013-04-29 10:27:53 <jgm> Is there any consideration of breaking bitcoind in to its various components? Daemon/datastore/GUI/wallet is the obvious split, in which case a lot of functionality like this could be added as standalone pieces which wouldn't affect the core bitcoin process
834 2013-04-29 10:28:04 <syskk> sipa: getting this error: error: cannot call member function 'virtual void CKeyStore::GetKeys(std::set<CKeyID, std::less<CKeyID>, std::allocator<CKeyID> >&) const' without object
835 2013-04-29 10:28:08 <jgm> (Once the split has occurred, of course; that itself would be a big job)

837 2013-04-29 10:28:15 <jgarzik> jgm: yes, old thoughts
838 2013-04-29 10:28:15 <sipa> syskk: you need to call it on the wallet
839 2013-04-29 10:29:07 * sipa would first like to see the wallet split off into a SPV client
840 2013-04-29 10:29:17 <syskk> sipa: thanks
841 2013-04-29 10:29:23 <buZz> jgm: i'd like to see the bitcoind to be made multi-coin
842 2013-04-29 10:29:25 <sipa> but that's not compatible with Gavin's idea of monitoring the mempool to make fee decisions
843 2013-04-29 10:29:48 <buZz> jgm: its just so pointless to have 99% the same code running multiple times, imho
844 2013-04-29 10:30:08 Diablo-D3 is now known as DiabloD3
845 2013-04-29 10:30:30 <jgm> buZz: no offence meant, but given that a lot of the forks are for code-related reasons as much as philosophical reasons that seems like just degenerating into a binfest
846 2013-04-29 10:30:56 <buZz> hmm yeah i get what you mean
847 2013-04-29 10:30:57 <jgm> jgarzik: have those thoughts been place on the "too scary" pile or are they likely to progress?
848 2013-04-29 10:31:41 <The_Fly> +1 for modularisation of bitcoin
849 2013-04-29 10:31:55 <sipa> there are several changes involved here
850 2013-04-29 10:32:06 <The_Fly> and quite breaking changes
851 2013-04-29 10:32:07 <jgarzik> jgm: It is lots of big changes
852 2013-04-29 10:32:12 <jgarzik> jgm: each with risk
853 2013-04-29 10:32:16 <sipa> first of is modularization of the code - not necessarily even splitting it into several binaries or processes
854 2013-04-29 10:32:23 <syskk> sipa: does that sound right? http://pastebin.com/kdivfqVz
855 2013-04-29 10:32:44 <The_Fly> it is something for a major version number in the milestones perhaps
856 2013-04-29 10:33:07 <sipa> syskk: that'll just get you key ids, but yes
857 2013-04-29 10:33:36 <sipa> not sure if CKeyID has a ToString, but don't expect addresses to show up
858 2013-04-29 10:34:08 TD has joined
859 2013-04-29 10:34:11 <jgm> Yep suspect that the risk is relatively high. Trouble is that at some stage (if not already) it's really going to hold back bitcoin development. If, for example, adding new user-facing features to wallets is considered too dangerous due to potential side-effects to the core daemon that's not a great situation to be in

861 2013-04-29 10:34:34 <sipa> jgm: i'm sure it is holding back development
862 2013-04-29 10:34:55 <jgarzik> indeed
863 2013-04-29 10:35:20 <jgarzik> never enough developer bandwidth to fix immediate things + all the Things That Need To Be Done
864 2013-04-29 10:35:28 <sipa> unfortunately, modularization is not given a high priority (we're too busy with keeping up with other things...)
865 2013-04-29 10:35:37 <The_Fly> ive got the 0mq support up to date with whats in master
866 2013-04-29 10:35:48 <syskk> sipa: it does. its showing me a bunch of strings. what is the difference between Key ids and private keys? how do i get the private key from the key id?
867 2013-04-29 10:35:51 <The_Fly> merge was trivial changes to thread creation/ anagement
868 2013-04-29 10:36:01 <The_Fly> and added walletnotify 0mq message
869 2013-04-29 10:36:02 <sipa> syskk: as i said, use GetKey or GetSecret
870 2013-04-29 10:36:11 <syskk> sipa: ok thanks
871 2013-04-29 10:36:14 <sipa> The_Fly: nice
872 2013-04-29 10:36:20 <The_Fly> anyone able to help with rabbitmq? i found a 0mq/rabbitmq adapter
873 2013-04-29 10:36:23 <jgm> Hmm... what do you reckon would be the lowest-danger/easiest-to-tackle modularization piece? Not sure I have the time, but if I could at least take a look and work out if I have the time to tackle something
874 2013-04-29 10:36:23 <The_Fly> sipa: ty

882 2013-04-29 10:37:04 <The_Fly> updated 0mq
883 2013-04-29 10:37:15 <sipa> oh, you're not the original author?
884 2013-04-29 10:37:19 <The_Fly> no

886 2013-04-29 10:37:34 <jgm> sipa: heh, any list out there of what needs testing?
887 2013-04-29 10:37:36 <The_Fly> just his branch had not been merged and was stale
888 2013-04-29 10:37:46 <The_Fly> ok np
889 2013-04-29 10:37:47 <sipa> jgm: any pull request :)
890 2013-04-29 10:38:32 <The_Fly> anyone played with https://github.com/rabbitmq/rmq-0mq/wiki ?
891 2013-04-29 10:39:19 <jgm> sipa: there are a lot of them out there, any prioritization? Apart from any I raise myself, of course
892 2013-04-29 10:41:22 <sipa> jgm: those that are tagged with 0.8.2

895 2013-04-29 10:44:44 <syskk> sipa: what is the difference between getkey and getsecret?
896 2013-04-29 10:45:00 <sipa> syskk: one gives you a CKey, the other gives you a CSecret
897 2013-04-29 10:45:18 <sipa> CKey is more powerful, allows conversion/signing/verification, CSecret is just the raw secret
898 2013-04-29 10:45:23 <sipa> CSecret is likely what you want here
899 2013-04-29 10:45:38 <syskk> ok
900 2013-04-29 10:45:47 <syskk> which one does dumpprivkey return?
901 2013-04-29 10:45:58 <sipa> you can't show a CKey
902 2013-04-29 10:46:02 <syskk> CSecret right?
903 2013-04-29 10:46:05 <sipa> yes
904 2013-04-29 10:46:19 <sipa> CKey is a wrapper around some OpenSSL functions that deal with crypto
905 2013-04-29 10:46:38 <sipa> look at the dumpprivkey cod
906 2013-04-29 10:46:57 <sipa> syskk: tbh, i was planning on adding a dumpwallet very soon

911 2013-04-29 10:49:20 <syskk> sipa: why does it show like 20+ secrets but i only actually have 2 receive addresses
912 2013-04-29 10:49:41 <sipa> syskk: it will include 100 key pool addresses, and all your change addresses
913 2013-04-29 10:49:52 <sipa> neither of which are visible in the GUI
914 2013-04-29 10:50:05 <syskk> got it
915 2013-04-29 10:50:25 <syskk> actually there's something weird⦠all secrets start with K or L

926 2013-04-29 10:54:54 <syskk> the ones that i can get using dumpprivkey
927 2013-04-29 10:55:19 <sipa> sure?
928 2013-04-29 10:56:20 <syskk> well im not using this wallet so let me pastebin the output

934 2013-04-29 10:58:46 <syskk> im probably misunderstanding something
935 2013-04-29 10:59:00 <sipa> they use a different encoding for private keys, it seems
936 2013-04-29 10:59:02 <sipa> no idea which
937 2013-04-29 10:59:26 <syskk> ah ok
938 2013-04-29 10:59:52 <syskk> why are there so many private keys? are they all important?
939 2013-04-29 11:00:05 <SomeoneWeird> keypool?
940 2013-04-29 11:00:06 <syskk> according to blockchain.info those 2 private keys are enough to export my wallet
941 2013-04-29 11:00:08 <sipa> do you understand the purpose of the keypool?
942 2013-04-29 11:00:16 <syskk> no :O
943 2013-04-29 11:00:38 <sipa> bitcoind's wallet uses new addresses continuously for privacy (every change goes to a fresh address)
944 2013-04-29 11:00:42 marr has quit (Ping timeout: 268 seconds)
945 2013-04-29 11:00:51 <sipa> that means that at every transaction, your wallet backups would become outdated
946 2013-04-29 11:01:00 <sipa> so they contain 100 future keys already
947 2013-04-29 11:01:08 <sipa> and new ones are taken from that pool
948 2013-04-29 11:01:08 <syskk> ah ok just read the wiki
949 2013-04-29 11:01:29 <The_Fly> this relates to my question earlier about decentralising the wallets
950 2013-04-29 11:01:41 <The_Fly> now that i have 0mq running i'd like to give it a shot, somehow
951 2013-04-29 11:02:02 <The_Fly> (signing transactions and passing to the daemon/p2p/database process)
952 2013-04-29 11:02:27 <syskk> sipa: how do i find out which keys are from the key pool and which are not?
953 2013-04-29 11:02:30 <The_Fly> i think the stumbling block last time i raised it was how to form the transaction correctly
954 2013-04-29 11:03:10 <The_Fly> which requires you to store locally (with respect to the wallet) some information about the blockchain
955 2013-04-29 11:03:11 <sipa> syskk: public addresses will have a corresponding entry in mapAddressBook
956 2013-04-29 11:03:31 <sipa> The_Fly: not really - you just the need unspent outputs
957 2013-04-29 11:03:36 <syskk> sipa: ok thanks
958 2013-04-29 11:03:37 <sipa> which are maintained by the wallet
959 2013-04-29 11:05:05 <The_Fly> ok, and a keypool local to the wallet right?
960 2013-04-29 11:05:18 <The_Fly> which it can grow as necessary? (or not?)
961 2013-04-29 11:05:18 <sipa> yes?
962 2013-04-29 11:05:23 <sipa> yes, sure
963 2013-04-29 11:05:31 <sipa> but what are you trying to do?
964 2013-04-29 11:06:33 <The_Fly> multiple projects which use bitcoin, so want each to have a separate wallet on a separate box, talking to main bitcoind over 0mq
965 2013-04-29 11:07:00 <sipa> you're implementing a wallet from scratch?
966 2013-04-29 11:07:20 _flow_ has joined
967 2013-04-29 11:07:31 <The_Fly> i might have to
968 2013-04-29 11:07:55 <The_Fly> either that or use codeshark's multiple wallet support
969 2013-04-29 11:08:23 <The_Fly> which may be an option, but is less secure
970 2013-04-29 11:08:34 giusepp__ has joined
971 2013-04-29 11:09:34 <The_Fly> having the private keys on very restricted machines (accessible only within the local network) seems desirable
972 2013-04-29 11:11:59 <The_Fly> at least the externalisation of transaction signing would be something i'd like to have
973 2013-04-29 11:12:42 <The_Fly> the main bitcoind process could still respond to wallet specific getbalance/etc queries, just move the signing
974 2013-04-29 11:13:22 <The_Fly> i assume you only need the public keys of your addresses and the blockchain to know a wallet's balance?

977 2013-04-29 11:15:34 <sipa> yes
978 2013-04-29 11:15:53 <sipa> but you don't need the blockchain... just which outputs you can still spend
979 2013-04-29 11:16:12 <The_Fly> i dont need the blockchain to sign, just outputs, yes...
980 2013-04-29 11:16:19 <sipa> obviously you infer that information from the chain by monitoring new blocks, but once you have that, you don't need the chain anymore
981 2013-04-29 11:16:33 <sipa> arguably, you don't need to *have* the chain, you just need to observe it
982 2013-04-29 11:16:42 <The_Fly> and update state
983 2013-04-29 11:16:58 <The_Fly> add db records (where they pertain to your wallet(s))
984 2013-04-29 11:17:51 <The_Fly> i placed the BZmq_SendWalletTransaction within the same function that -walletnotify thread was forked
985 2013-04-29 11:18:38 <The_Fly> so i should see all events
986 2013-04-29 11:18:53 <The_Fly> but say i wanted to import a wallet...
987 2013-04-29 11:19:06 <DiabloD3> hey sipa
988 2013-04-29 11:19:07 <The_Fly> i'd have to scan the blockchain for all outputs
989 2013-04-29 11:19:14 <DiabloD3> whats the maximum number of sends in sendmany?
990 2013-04-29 11:20:00 <sipa> DiabloD3: no specific limit
991 2013-04-29 11:20:07 <sipa> The_Fly: yes

1021 2013-04-29 11:40:50 <The_Fly> i think the 0mq+multiwallet will do nicely
1022 2013-04-29 11:41:08 <The_Fly> but, im curious as to how much pentesting has been done with bitcoind
1023 2013-04-29 11:41:32 <The_Fly> are there any remote code execution, buffer overflow, etc. exploits lurking in the code
1024 2013-04-29 11:41:41 <jgm> Eek, which version of boost does bitcoin build with on the test server? Just tried a patch and got a failure due to a missing function which AFAIK has been in there for years...

1038 2013-04-29 11:47:04 <alaricsp> In general, only trust open-source wallets, and even then guardedly so
1039 2013-04-29 11:47:25 <The_Fly> seems multiwallet is missing a createwallet RPC func
1040 2013-04-29 11:47:39 <alaricsp> In theory, the bitcoind devs could try and sneak in a backdoor that, when you enter your wallet passphrase, sends them all your BTC; but being open source, they'd need to be sneakier in doing so.
1041 2013-04-29 11:47:39 <The_Fly> im not sure how i'd create a new "empty" wallet.dat
1042 2013-04-29 11:48:01 <jgm> Boost 1.46 is the earliest version which defaults to filesystem version being 3, which is what the patch needs. Guess I'll have to ifdef it then, but we must be running a pretty old version of boost
1043 2013-04-29 11:48:10 <alaricsp> Prepackaged binaries from distros could have extra patches added beyond what's in the source, too.
1044 2013-04-29 11:48:15 <DiabloD3> goddamnit, why the fuck is sendmany so broken
1045 2013-04-29 11:48:17 <sipa> jgm: we need to support fs v2 for now
1046 2013-04-29 11:48:21 <The_Fly> alaricsp: im building from source
1047 2013-04-29 11:48:22 <DiabloD3> no matter what syntax I give it, it bitches
1048 2013-04-29 11:48:28 <DiabloD3> error: value is type int, expected obj
1049 2013-04-29 11:48:33 <DiabloD3> WHAT DO YOU WANT FROM ME
1050 2013-04-29 11:48:43 <sipa> DiabloD3: what do you send?
1051 2013-04-29 11:48:45 <The_Fly> it wants to break you
1052 2013-04-29 11:48:47 <sivu> alaricsp: so you always go through the whole code of an open source project before building and running the software?
1053 2013-04-29 11:48:59 <The_Fly> i suppose you dont have to
1054 2013-04-29 11:49:17 <The_Fly> on the assumption that enough eyes are looking to spot something
1055 2013-04-29 11:49:25 <DiabloD3> sipa: Ive tried sendmany address:btc, Ive tried sendmany {address:btc}, Ive tried sendmany {"address":btc}
1056 2013-04-29 11:49:28 <DiabloD3> sipa: all same error
1057 2013-04-29 11:49:30 <alaricsp> sivu: Nope. I just hope that somebody else would have spotted something :-)
1058 2013-04-29 11:49:30 <The_Fly> and that the main devs are also trustworthy
1059 2013-04-29 11:49:36 <alaricsp> sivu: I'm not saying it would be practical to do so, for me
1060 2013-04-29 11:49:57 <sipa> DiabloD3: what's your exact command line (or RPC object you send)?
1061 2013-04-29 11:50:01 <alaricsp> sivu: But perhaps a bank or other large organisation using bitcoin might have their own trusted builds, and inspect every patch they pull down from the public repo.
1062 2013-04-29 11:50:06 <jgm> sipa: fair enough, will ifdef it and resubmit the patch
1063 2013-04-29 11:50:09 <The_Fly> surely some distro package repo has been hacked in the past to spread malicious binaries
1064 2013-04-29 11:50:13 <DiabloD3> sipa: bitcoind sendmany
1065 2013-04-29 11:50:18 <The_Fly> it could happy with bitcoind
1066 2013-04-29 11:50:23 <sipa> DiabloD3: you're not answering my question
1067 2013-04-29 11:50:28 <jgm> DiabloD3: Try '{"address1":btc,"address2":btc}'
1068 2013-04-29 11:50:34 <DiabloD3> sipa: I dont understand your question then
1069 2013-04-29 11:50:45 <DiabloD3> sipa: I wrote it on the command line verbatim
1070 2013-04-29 11:50:59 <DiabloD3> jgm: with the single quotes?
1071 2013-04-29 11:51:05 <jgm> yep

1073 2013-04-29 11:51:16 <jgm> you need the single quotes to stop the shell from parsing it, and the double quotes to make it valid JSON
1074 2013-04-29 11:51:33 <The_Fly> any way to create a blank wallet.dat with bitcoind?
1075 2013-04-29 11:51:44 <sipa> DiabloD3: 'bitcoind sendmany' will not do anything (it will show you the help message), and '{"address":btc}' is not a full command
1076 2013-04-29 11:52:03 <The_Fly> i suppose i could just copy from a seed wallet.dat
1077 2013-04-29 11:52:06 <DiabloD3> sipa: er, I clearly said sendmany first.
1078 2013-04-29 11:52:08 <sipa> DiabloD3: so i'll try to help you, but i'd like to see exactly what you're doing
1079 2013-04-29 11:52:14 <DiabloD3> [07:26:45] <DiabloD3> sipa: Ive tried sendmany address:btc, Ive tried sendmany {address:btc}, Ive tried sendmany {"address":btc}
1080 2013-04-29 11:52:19 <DiabloD3> thats the three I tried
1081 2013-04-29 11:52:38 <DiabloD3> sendmany '{"address":btc}' just tells me the sendmany help as an error
1082 2013-04-29 11:52:42 <sipa> DiabloD3: i'm NOT going to try to infer what you're doing from the bits and pieces you've given m

1086 2013-04-29 11:52:55 <DiabloD3> sipa: I dont understand your question then, this is what Ive wrote verbatim
1087 2013-04-29 11:53:21 <DiabloD3> that is the command I gave bitcoind
1088 2013-04-29 11:54:13 <sipa> DiabloD3: ok, first of all, you need the account to debit
1089 2013-04-29 11:54:26 <sipa> the command is sendmany <fromaccount> <amounts>
1090 2013-04-29 11:54:29 <DiabloD3> er, why isnt that optional?
1091 2013-04-29 11:54:38 <DiabloD3> I dont use accounts
1092 2013-04-29 11:54:38 <sipa> is that relevant?
1093 2013-04-29 11:54:47 <DiabloD3> yes, its relevant because sendtransaction doesnt require it
1094 2013-04-29 11:54:51 <sipa> yes, it could be optional, but it clearly isn't
1095 2013-04-29 11:54:53 <DiabloD3> which makes the API confusing
1096 2013-04-29 11:55:02 <sipa> and the help message clearly indicates this

1102 2013-04-29 11:56:22 <DiabloD3> sendmany is useless to me

1108 2013-04-29 11:57:07 <sipa> DiabloD3: known problem, and i'm in favor of fixing it
1109 2013-04-29 11:57:15 <sipa> DiabloD3: but it requires changing the API unfortunately
1110 2013-04-29 11:57:32 <sipa> (as JSON doesn't allow duplicate keys in objects)
1111 2013-04-29 11:57:43 <DiabloD3> why is it a json array anyhow
1112 2013-04-29 11:57:53 <sipa> it isn't
1113 2013-04-29 11:57:57 <sipa> it's a json object
1114 2013-04-29 11:58:01 <DiabloD3> whatever
1115 2013-04-29 11:58:06 <sirdefaced> lol
1116 2013-04-29 11:58:06 <DiabloD3> its one of those
1117 2013-04-29 11:58:10 <DiabloD3> why cant it just be a list of text
1118 2013-04-29 11:58:24 <sipa> it could be [[address,amount],[address,amount],...] for example, that would work
1119 2013-04-29 11:58:59 <DiabloD3> yes, so break the api and make it useful
1120 2013-04-29 11:59:27 <jgm> The JSON API is... nonstandard, shall we say
1121 2013-04-29 11:59:36 <sipa> yeah, it's a mess
1122 2013-04-29 11:59:36 <DiabloD3> sipa: okay so wait
1123 2013-04-29 11:59:45 <DiabloD3> why is this giving me that error anyhow?

1125 2013-04-29 11:59:54 <DiabloD3> bitcoind as an rpc client should be repeating what I say

1133 2013-04-29 12:00:32 <DiabloD3> yes what sipa said
1134 2013-04-29 12:00:41 * alaricsp wonders why you'd want to do that
1135 2013-04-29 12:00:49 <sipa> DiabloD3: the person who implemented it, thought that it was a bad idea to support duplicate addresses
1136 2013-04-29 12:00:54 <DiabloD3> alaricsp: because of broken things like SD
1137 2013-04-29 12:00:57 <alaricsp> Perhaps if you were building something like satoshidice?
1138 2013-04-29 12:00:59 <alaricsp> Ah-hah
1139 2013-04-29 12:01:27 <DiabloD3> so wait, why the hell does SD support sendmany
1140 2013-04-29 12:01:29 <DiabloD3> if I cant sendmany
1141 2013-04-29 12:01:34 <jgm> Yep no way of doing that as valid JSON given the current format. Why not merge the outputs prior to calling sendmany?
1142 2013-04-29 12:01:45 <DiabloD3> jgm: because of SD
1143 2013-04-29 12:02:54 <sipa> well, you can always use the raw transaction API :p
1144 2013-04-29 12:02:56 <alaricsp> SD may be running a patched bitcoind
1145 2013-04-29 12:03:04 <DiabloD3> alaricsp: that doesnt help me, now does it
1146 2013-04-29 12:03:07 <sipa> SD uses a heavily-patched BitcoinJ
1147 2013-04-29 12:03:08 <DiabloD3> I cant _send_ them a sendmany
1148 2013-04-29 12:03:14 <jgm> Okay I get it. Although if you want to burn all your money it's friendlier to the network if you do it all with one big roll of the dice rather than lots of little ones.
1149 2013-04-29 12:03:15 <alaricsp> DiabloD3: Sadly, no...
1150 2013-04-29 12:03:28 <DiabloD3> sipa: meeeeehh, that confuses the hell out of me
1151 2013-04-29 12:03:37 <sipa> DiabloD3: understandable
1152 2013-04-29 12:03:52 <DiabloD3> all I want to do is make SD pay me lots of money
1153 2013-04-29 12:03:59 <DiabloD3> because I think I can consistently win against it
1154 2013-04-29 12:04:11 <sipa> then perhaps you need a course in statistics
1155 2013-04-29 12:04:19 <DiabloD3> no, I think the people who run SD do
1156 2013-04-29 12:04:39 <DiabloD3> Ive already been doing it, but tx fees are eating my lunch
1157 2013-04-29 12:05:28 <jgm> Patch sendmany locally then. There's no reason that it isn't allowed in a raw transaction
1158 2013-04-29 12:05:46 <jgm> I can do it if you cut me in on the profits :)
1159 2013-04-29 12:06:01 <sipa> jgm: also on the losses?

1197 2013-04-29 12:25:56 <The_Fly> i think happened when i moved wallet.dat to another name, because i wanted bitcoind to create a new wallet for me
1198 2013-04-29 12:29:37 <The_Fly> ok cool, ive isolated it to that case
1199 2013-04-29 12:29:48 <The_Fly> bug only happens when bitcoind created a new wallet.dat on spinup

1269 2013-04-29 13:40:21 <sipa> just copy the blocks directory then, set txindex on the new node, and do a reindex
1270 2013-04-29 13:40:36 <jouke> ok thanks
1271 2013-04-29 13:40:40 <sipa> actually, only the blocks/blk* files
1272 2013-04-29 13:40:45 <sipa> no need to copy the undo files or the index

1433 2013-04-29 16:23:38 <ColinT> Is the UI and Bitcoin source all mashed together still?
1434 2013-04-29 16:26:07 <wumpus> nope; the ui source is in src/qt, the core source in just src
1435 2013-04-29 16:26:24 <ColinT> cool - this "json" folder - do I need that?
1436 2013-04-29 16:26:29 <wumpus> yes
1437 2013-04-29 16:26:39 <ColinT> (if I don't want the UI?)
1438 2013-04-29 16:26:52 <wumpus> especially if you don't want the ui
1439 2013-04-29 16:27:03 <ColinT> hehe
1440 2013-04-29 16:27:06 <wumpus> I suppose you want some kind of entry point? :P
1441 2013-04-29 16:27:34 <wumpus> if you strip the json stuff as well as the ui, you have an interesting node

1451 2013-04-29 16:29:00 <The_Fly> wumpus: yes but merge messages locally are not what i see in github, so github must detect that you merged a branch in a fork (when you merge with a branch from another remote)
1452 2013-04-29 16:29:21 <sipa> github has lots of magic
1453 2013-04-29 16:29:30 <sipa> and cats
1454 2013-04-29 16:29:37 <The_Fly> that clever octopus
1455 2013-04-29 16:30:04 <wumpus> The_Fly: it depends on the options that you provide; by default, in the case of a "fast forward" merge you don't get a merge message, but otherwise it will generate one

1458 2013-04-29 16:31:07 <wumpus> github always generates a merge message, even on a fastforward/trivial merge
1459 2013-04-29 16:31:29 <The_Fly> ok, im merging locally
1460 2013-04-29 16:31:39 <The_Fly> and in the bitcoin repo i see all the merge messages for pull request merges
1461 2013-04-29 16:32:10 <wumpus> --no-ff Create a merge commit even when the merge resolves as a fast-forward.
1462 2013-04-29 16:32:12 <The_Fly> but here im just merging master into some outdated feature branches of other forks (e.g. fredan/0mq and codeshark/multiwallet)
1463 2013-04-29 16:32:26 <The_Fly> i am using --no-ff at work
1464 2013-04-29 16:32:38 <The_Fly> to force a merge message
1465 2013-04-29 16:32:42 <wumpus> yes
1466 2013-04-29 16:32:54 <The_Fly> confusion is that githubs merge message for pull requests is different than that of gits
1467 2013-04-29 16:33:10 <The_Fly> but that makes sense because they'll be doing the merge
1468 2013-04-29 16:33:23 <The_Fly> when done by the web interface
1469 2013-04-29 16:33:40 <wumpus> indeed, the web interface includes the pull request #
1470 2013-04-29 16:33:54 <The_Fly> in my case (fixing up these stale branches) am i best to merge them master, or merge master into them, or does it not matter
1471 2013-04-29 16:35:15 <wumpus> that only depends on where you want the changes
1472 2013-04-29 16:35:26 <The_Fly> i suppose it probably makes sense to merge master into, as i'll be submitting another pull request
1473 2013-04-29 16:35:50 <wumpus> may be better to use rebase in that case
1474 2013-04-29 16:36:06 <The_Fly> have been doing that so far
1475 2013-04-29 16:36:20 <wumpus> it allows you to avoid a labyrinth of merge commits
1476 2013-04-29 16:36:55 <wumpus> though it's a matter of personal taste, some people like it that way, but with bitcoin we prefer pull requests that don't contain merges themselves

1482 2013-04-29 16:38:19 <wumpus> then you get conflicts while rebasing, which you have to resolve before you can continue

1541 2013-04-29 17:09:57 <topace> is there any way of knowing how often the keypool gets refilled? or does it generate a new address each time it uses one ?

1544 2013-04-29 17:10:21 <topace> basically i want to make sure my backups are frequent enough that i have all keeys in the keypool before they are used.
1545 2013-04-29 17:10:35 <Scrat> topace: does exactly what you said. getinfo gives you the pool size
1546 2013-04-29 17:11:06 <tonikt> sipa: ... yeah, I though there was something wrong with the value, but there was a bug in my verify function. :P
1547 2013-04-29 17:11:50 <topace> keypoololdest is the timestamp of the oldest unused address in the keypool?

1549 2013-04-29 17:12:13 <tonikt> it would indeed be very unlikely to generate a value form outside the range.

1579 2013-04-29 17:23:11 <Diablo-D3> I ended up coding a large scale STM implementation that automatically retires attempts using longjmp

1606 2013-04-29 17:29:33 <Diablo-D3> theres also an upper limit of supporting threads
1607 2013-04-29 17:29:51 <Diablo-D3> once 16 and 24 and 32 core CPUs become the norm, threads wont be able to survive on a lot of use cases
1608 2013-04-29 17:30:21 <Diablo-D3> you don't have this problem if you use a consumer/producer type of pipeline done asynchronously

1810 2013-04-29 19:48:59 <etotheipi_> this is a longshot, but I don't suppose you could have *two* P2SH scripts in a single TxOut script, could you? The P2SH "trigger" only occurs on transactions that meet the special template, not each piece of the script that matches the template...?
1811 2013-04-29 19:50:28 <sipa> what would be the meaning of two P2SH scripts in one output?
1812 2013-04-29 19:50:56 <sipa> (answer is no, the entire script must match the template)
1813 2013-04-29 19:51:01 <etotheipi_> sipa: okay

1816 2013-04-29 19:52:08 <nsh> depends on whether we allow americans to play
1817 2013-04-29 19:52:32 <sipa> obviously, MSVC runtime doesn't have it
1818 2013-04-29 19:52:34 <sipa> bah
1819 2013-04-29 19:52:45 <etotheipi_> sipa: isn't it part of the C std library?
1820 2013-04-29 19:52:50 <etotheipi_> or strftime?
1821 2013-04-29 19:53:01 <sipa> which "the" standard library are you talking about?
1822 2013-04-29 19:53:11 <sipa> glibc? posix? susv? xopen?

1836 2013-04-29 19:54:13 <gmaxwell> etotheipi_: shouldn't use C99 as a portability benchmark, MSFT doesn't implment it except where they did so accidentally as a result of supporting C++.
1837 2013-04-29 19:54:39 <etotheipi_> gmaxwell: interesting, I thought they did
1838 2013-04-29 19:54:46 <etotheipi_> but maybe it was just accidental
1839 2013-04-29 19:54:52 <etotheipi_> (to the degree that they did)

1841 2013-04-29 19:55:40 <gmaxwell> yea. no, they only support parts of C99 that are in C++. For example, they don't support C99 variable length arrays.

1878 2013-04-29 20:20:48 <syskk> why importing a private key is so slow?
1879 2013-04-29 20:21:30 <darksk1ez> I imagine its because it has to calculate the public key and then walk the blockchain looking for transactions for it.
1880 2013-04-29 20:21:53 <topi`> hmm, libboost 1.42 available for maverick, maybe that's good enough to compile bitcoind 0.8.x

1914 2013-04-29 20:36:43 <topi`> is everyone using the new openssl 1.0.x libs to compile bitcoind? I looked at the changes in libssl vs. 0.9.8o in maverick, and they're very small
1915 2013-04-29 20:37:03 <topi`> new features are cms and ts but probably not used in bitcoi
1916 2013-04-29 20:37:17 <syskk> is there a way to update my balance without restarting bitcoind?
1917 2013-04-29 20:37:34 <gmaxwell> ...
1918 2013-04-29 20:37:41 <gmaxwell> thats what the rescan that you disabled is for.
1919 2013-04-29 20:38:10 <syskk> i know⦠but isnt it possible to import a bunch of keys

2133 2013-04-29 21:40:32 <fishfish> Good evening! fishfish question of the night: is the QR code that displays a bitcoin public address any different, or special from any other QR? reason I ask is that I want to have my web app (in node.js) return a QR code. Thank you!
2134 2013-04-29 21:40:58 <sipa> is what way would it be different/
2135 2013-04-29 21:41:06 <sipa> it's just a QR code with an address
2136 2013-04-29 21:41:17 <The_Fly> < Diablo-D3> once 16 and 24 and 32 core CPUs become the norm, threads wont be able to survive on a lot of use cases
2137 2013-04-29 21:41:19 <fishfish> gotcha. So any qr generator will do. Happy days!
2138 2013-04-29 21:41:20 <The_Fly> < Diablo-D3> you don't have this problem if you use a consumer/producer type of pipeline done asynchronously
2139 2013-04-29 21:41:22 <fishfish> thank you sipa.
2140 2013-04-29 21:41:28 <jchp> fishfish: it will probably be an address using "bitcoin:" as part of the URI. more info: https://en.bitcoin.it/wiki/BIP_0021
2141 2013-04-29 21:42:09 <fishfish> thank you jchp.
2142 2013-04-29 21:42:12 <The_Fly> Diapolis: so we should split up bitcoind and compose it of several 0mq nodes? ;)
2143 2013-04-29 21:42:23 <The_Fly> *Diablo-D3
2144 2013-04-29 21:43:22 <The_Fly> btw i just completed the merge of codeshark/multiwallet into bitcoin/master
2145 2013-04-29 21:43:25 <The_Fly> runs fine
2146 2013-04-29 21:43:56 <The_Fly> except... that on shutdown I see a bitcoind: /usr/include/boost/thread/pthread/condition_variable_fwd.hpp:46: boost::condition_variable::~condition_variable(): Assertion `!pthread_mutex_destroy(&internal_mutex)' failed.
2147 2013-04-29 21:44:02 <The_Fly> so I'm trying to track that down
2148 2013-04-29 21:44:17 <The_Fly> then should be able to merge 0mq+multiwallet
2149 2013-04-29 21:44:26 <The_Fly> so one can subscribe to wallet.walletname
2150 2013-04-29 21:44:33 <The_Fly> etc

2154 2013-04-29 21:45:57 <The_Fly> if anyone has any debugging tips on how to track this boost error i'd appreciate it
2155 2013-04-29 21:46:01 <The_Fly> oh, you have?
2156 2013-04-29 21:46:10 <The_Fly> i could gdb and see... no?
2157 2013-04-29 21:46:26 <sipa> it'd be helpful to see which thread that's in
2158 2013-04-29 21:46:33 <The_Fly> a trace would be good wouldn't it
2159 2013-04-29 21:46:43 <The_Fly> would gdb give me a trace?

2163 2013-04-29 21:48:57 <sipa> if you don't strip them
2164 2013-04-29 21:49:06 <sipa> release builds are stipped, i think
2165 2013-04-29 21:49:26 <The_Fly> i'll look in the docs to see how to do a debug build
2166 2013-04-29 21:49:33 <The_Fly> is this fairly low priority?
2167 2013-04-29 21:49:41 <sipa> no, it has to be fixed before 0.8.2
2168 2013-04-29 21:49:50 <The_Fly> ok
2169 2013-04-29 21:50:00 <The_Fly> can you tell me, the destructor on ~CWallet
2170 2013-04-29 21:50:08 <The_Fly> i guess with the switch to CWalletManager
2171 2013-04-29 21:50:15 <The_Fly> the destructor is useless
2172 2013-04-29 21:50:18 <The_Fly> and can go
2173 2013-04-29 21:50:25 <The_Fly> right?

2176 2013-04-29 21:50:54 <syskk> any chance ill be able to build bitcoin for windows on my macbook air (virtualbox+ubuntu+lxc)?
2177 2013-04-29 21:52:50 <sipa> syskk: it's hard to build for windows, but this person described how he did it: https://bitcointalk.org/index.php?topic=149479.0
2178 2013-04-29 21:53:04 <sipa> or you mean gitian?
2179 2013-04-29 21:53:13 <sipa> gitian is nice if it works, but it takes some time to set up

2184 2013-04-29 21:54:11 <syskk> sipa: yeah, im trying to go gitian way for now but not much success.. always errors
2185 2013-04-29 21:57:43 <ahf> the bnProofOfWorkLimit constant in src/main.cpp is used to represent the maximum target, right?
2186 2013-04-29 21:57:55 <sipa> ahf: correct
2187 2013-04-29 21:58:36 <ahf> with the current implementation (~uint256(0) >> 32) the note on this page: https://en.bitcoin.it/wiki/Target about Bitcoin storing the target as a float and thus truncates it, is incorrect, right?
2188 2013-04-29 21:59:23 <sipa> it is correct
2189 2013-04-29 21:59:48 <sipa> the target is compressed to a custom 32-bit floating point format
2190 2013-04-29 22:00:00 <ahf> the compact format?
2191 2013-04-29 22:00:08 <syskk> gitian is stuck at "grabbing package manifest" is it a good or bad sign?
2192 2013-04-29 22:00:10 <sipa> yes?
2193 2013-04-29 22:00:14 <ahf> so the actual check happens against 0x00000000FFFF0000000000000000000000000000000000000000000000000000 and not 0x00000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

2198 2013-04-29 22:00:25 <sipa> ahf: indeed
2199 2013-04-29 22:01:09 <The_Fly> ok, because we have ThreadFlushWalletDB we can get rid of the ~CWallet(), if a wallet is UnregisterWallet'd it will have a zero refcount and have its dbfile flushed
2200 2013-04-29 22:01:13 <syskk> oh well, restarted the script now :(
2201 2013-04-29 22:01:52 <syskk> im getting this now : sudo: unable to resolve host my-hostname-here

2315 2013-04-29 23:33:54 <The_Fly> not sure if bug has existed several commits back
2316 2013-04-29 23:34:00 <buZz> RPC wont work until download is done
2317 2013-04-29 23:34:09 <The_Fly> ok, conflicting info
2318 2013-04-29 23:34:23 <The_Fly> it seems consistent accross my branches and in master, so at least i know ive not caused it!
2319 2013-04-29 23:34:37 <The_Fly> is this an intentional feature?
2320 2013-04-29 23:34:50 <The_Fly> surely a download can be interrupted?
2321 2013-04-29 23:34:54 <sipa> buZz: that's not true
2322 2013-04-29 23:34:58 <buZz> killall bitcoind :P
2323 2013-04-29 23:35:02 <The_Fly> no
2324 2013-04-29 23:35:03 <buZz> sipa: didnt reply to me

2326 2013-04-29 23:35:17 <sipa> a few commands are disabled before download is completed, such as getwork/getblocktemplate
2327 2013-04-29 23:35:20 <buZz> i am just saying all bitcoind's i've had, had the behaviour of not replying during RPC

2331 2013-04-29 23:35:58 <The_Fly> this is a bug
2332 2013-04-29 23:36:25 <sipa> The_Fly: ever?
2333 2013-04-29 23:36:29 <sipa> or when?
2334 2013-04-29 23:36:46 nsillik has joined
2335 2013-04-29 23:36:52 <The_Fly> well i guess if i squeeze the stop in immediately before download it will work, but i dont know
2336 2013-04-29 23:37:17 <sipa> no, what exactly are you doing, what do you observe, what do you expect
2337 2013-04-29 23:37:22 <The_Fly> i delete my blocks and chainstate dirs to get a new download going
2338 2013-04-29 23:37:30 <The_Fly> i start bitcoind in daemon mode
2339 2013-04-29 23:37:31 <sipa> why would you do that?
2340 2013-04-29 23:38:07 <The_Fly> what happens if those files are corrupted or you import just a wallet.dat somewhere and want to download the blockchain again?
2341 2013-04-29 23:38:16 <sipa> use -reindex
2342 2013-04-29 23:38:36 <sipa> and importing a wallet is just putting the file there (while bitcoin isn't running)
2343 2013-04-29 23:38:37 <The_Fly> sure, but that's not dealing with these cases... you might even be starting a new node on a box
2344 2013-04-29 23:38:48 <The_Fly> and want to shut it down
2345 2013-04-29 23:38:59 <The_Fly> you cant if you are waiting for the downloading to stop
2346 2013-04-29 23:39:03 <The_Fly> which could be a while right?

2350 2013-04-29 23:39:34 <The_Fly> ok...
2351 2013-04-29 23:41:02 <The_Fly> well now because i kill -9 the last run i have a corrupted block
2352 2013-04-29 23:41:07 <The_Fly> ERROR: bool CBlock::ReadFromDisk(const CDiskBlockPos&)() : deserialize or I/O error
2353 2013-04-29 23:41:10 <The_Fly> *** Failed to read block
2354 2013-04-29 23:41:20 <sipa> heh
2355 2013-04-29 23:41:25 <The_Fly> which explains why i was seeing this earlier, and points towards an unclean shutdown being the cause
2356 2013-04-29 23:41:28 <buZz> dont kill -9
2357 2013-04-29 23:41:31 <sipa> that should be impossibe whatsoever
2358 2013-04-29 23:41:32 <buZz> just kill
2359 2013-04-29 23:41:35 <buZz> without -9
2360 2013-04-29 23:41:41 <buZz> let it write away its files
2361 2013-04-29 23:41:44 <buZz> -9 does not do this

2364 2013-04-29 23:42:11 <The_Fly> if it doens't listen to the daemon stop rpc command a sig_term will do not very much
2365 2013-04-29 23:42:13 <sipa> i have no clue what you're trying to do, what you've done, or how you got in which state
2366 2013-04-29 23:42:26 <The_Fly> never mind... i'll fix this myself
2367 2013-04-29 23:42:39 <The_Fly> it's happening on master, on a fresh .bitcoin folder
2368 2013-04-29 23:42:39 <sipa> ... can you please just paste a few lines from debug.log?
2369 2013-04-29 23:42:43 <The_Fly> ok...
2370 2013-04-29 23:42:44 <sipa> i might just be able to tell you

2378 2013-04-29 23:49:04 <The_Fly> but somehow it got out of state switching between 0mq and multiwallet branches (which ive both merged with most recent master)

2381 2013-04-29 23:49:30 <sipa> i meant a piece of debug.log from where your RPC wasn't working
2382 2013-04-29 23:49:55 <The_Fly> im going to get you that
2383 2013-04-29 23:50:12 <The_Fly> removal of blocks and chainstate dirs may be the only trigger...
2384 2013-04-29 23:50:19 <The_Fly> but it's the first time ive tried that
2385 2013-04-29 23:50:40 <The_Fly> if there's another (cleaner, better) way to get a full re-download, please tell me

2390 2013-04-29 23:52:43 <sipa> The_Fly: to re-download you need indeed to delete blocks/chainstate, but if you just want to rebuild the database (which is code-wise very similar to redownloading), run with -reindex

2401 2013-04-29 23:55:28 <sipa> it happens more than you think
2402 2013-04-29 23:55:28 <The_Fly> but strange that when i did (confirming now) that RPC would not accept connections
2403 2013-04-29 23:55:40 <sipa> and certainly more than necessary
2404 2013-04-29 23:55:42 <The_Fly> ok... so a reason to see if i can find the steps to recreate
2405 2013-04-29 23:56:36 <sipa> there is one case that would explain what you saw
2406 2013-04-29 23:56:57 <sipa> if you'd delete chainstate but not blocks, bitcoin will at startup try to connect its best block (in one go)
2407 2013-04-29 23:57:28 <The_Fly> think i definitely deleted both, but it is a possibility
2408 2013-04-29 23:57:37 <sipa> and that case take a while, and perhaps it can't be interrupted in that case (that'd be a bug, but it's not a frequently used code path)
2409 2013-04-29 23:57:50 <The_Fly> true
2410 2013-04-29 23:57:53 <sipa> it's sort of a hidden feature to do a performance test of the block verification code
2411 2013-04-29 23:58:04 <sipa> as it does absolutely nothing but that
2412 2013-04-29 23:58:22 <The_Fly> ok, have not recreated with deletion of blocks/chainstate or switch to me 0mq-merge branch
2413 2013-04-29 23:58:41 <The_Fly> now try multiwallet...delete... and then i will get back to doing something more useufl
