2 2012-03-19 00:02:20 <etotheipi_> sipa, so when you decrypt a key, it previously used the hash of the 65-byte public key to decrypt. Is it now using the hash of the 33 byte public key?
3 2012-03-19 00:02:39 <etotheipi_> err.. hash of public key for IV

11 2012-03-19 00:10:31 <sipa> but that shouldn't be a problem
12 2012-03-19 00:11:15 <sipa> the only problem i can think of is that when verifying the integrity, if the public key is 33 bytes, you should compare it against the compressed form of the public key corresponding to the private key you just decrypted
13 2012-03-19 00:11:17 <etotheipi_> sipa, it's not a problem, I just want to make sure I get it right
14 2012-03-19 00:11:51 <etotheipi_> my code fails because it verifies the private key against the public key: which is incomprehendable to Armory right now

21 2012-03-19 00:23:18 <BlueMatt> (github really should let people mark stuff...)
22 2012-03-19 00:23:29 <luke-jr> ^
23 2012-03-19 00:23:40 <luke-jr> at least stuff like Bug/Feature/etc
24 2012-03-19 00:23:52 <BlueMatt> actually, github should replace their bugtracking system with a real bugtracking system...
25 2012-03-19 00:24:04 <luke-jr> ofc, I'd much prefer someone write a better competitor to GitHub
26 2012-03-19 00:24:12 <sipa> BlueMatt: how about i fix it, instead?
27 2012-03-19 00:24:17 <BlueMatt> that works too

33 2012-03-19 00:24:40 <BlueMatt> luke-jr: only if it can import from github...
34 2012-03-19 00:24:43 <BlueMatt> which is the issue
35 2012-03-19 00:24:51 <luke-jr> BlueMatt: ah, that might not be as simple
36 2012-03-19 00:25:11 <luke-jr> otoh, I can't imagine it'd be hard to script; happen to know if GitHub ToS allow it?
37 2012-03-19 00:25:20 <BlueMatt> nfc, Id assume so
38 2012-03-19 00:25:27 <BlueMatt> if they have an api, Id assume so
39 2012-03-19 00:25:48 <deoxxa> could probably ask them nicely for an export
40 2012-03-19 00:26:33 <luke-jr> who wants to research the best bugtracker? :p
41 2012-03-19 00:26:48 <deoxxa> depends on what you want it to do
42 2012-03-19 00:26:56 <BlueMatt> Id say track bugs
43 2012-03-19 00:27:10 <deoxxa> good news: github has that built in
44 2012-03-19 00:27:17 <deoxxa> now, what do you *really* want it to do
45 2012-03-19 00:27:32 <BlueMatt> have sane tagging mechanisms

60 2012-03-19 00:29:55 <Diablo-D3> I can write closes #bugnumber and github automatically closes those
61 2012-03-19 00:30:06 <BlueMatt> no, it just links to the issue
62 2012-03-19 00:30:08 <Diablo-D3> I can assign and tag bugs in the bug tracker
63 2012-03-19 00:30:11 <Diablo-D3> bluematt: nope
64 2012-03-19 00:30:15 <Diablo-D3> it actually closes it
65 2012-03-19 00:30:20 <sipa> it closes it
66 2012-03-19 00:30:21 <BlueMatt> Diablo-D3: no, you can give it a label that says "Diablo"
67 2012-03-19 00:30:28 <BlueMatt> that isnt assignment
68 2012-03-19 00:30:32 <Diablo-D3> no, you can assign
69 2012-03-19 00:30:36 <BlueMatt> where?
70 2012-03-19 00:30:54 <sipa> BlueMatt: with push rights, you can
71 2012-03-19 00:31:01 <BlueMatt> thats worthless though...
72 2012-03-19 00:31:03 <Diablo-D3> bluematt: Im looking at, say, this
73 2012-03-19 00:31:06 <Diablo-D3> https://github.com/Diablo-D3/DiabloMiner/issues/39
74 2012-03-19 00:31:16 <Diablo-D3> I see a "No one is assigned [gear box drop down]"
75 2012-03-19 00:31:23 <Diablo-D3> I click the gear
76 2012-03-19 00:31:31 <Diablo-D3> it pops up a pop up that allows me to assign
77 2012-03-19 00:31:33 <BlueMatt> ok, so its worthless unless you can give everyone push rights
78 2012-03-19 00:31:37 <BlueMatt> which is stupid
79 2012-03-19 00:31:41 <Diablo-D3> huh?
80 2012-03-19 00:31:42 <freewil> BlueMatt, https://github.com/blog/831-issues-2-0-the-next-generation
81 2012-03-19 00:31:47 <Diablo-D3> outsiders should NEVER assign bugs
82 2012-03-19 00:31:48 <Diablo-D3> ever
83 2012-03-19 00:31:57 <Diablo-D3> if you dont have push rights, you're not a member of the project.
84 2012-03-19 00:32:10 <BlueMatt> not at all true
85 2012-03-19 00:32:14 <BlueMatt> see: bitcoin
86 2012-03-19 00:32:20 <Diablo-D3> yes, and bitcoin has basically one dev.
87 2012-03-19 00:32:21 <Diablo-D3> gavin.
88 2012-03-19 00:32:25 <BlueMatt> ???
89 2012-03-19 00:32:27 <Diablo-D3> the rest of you are just frequent committers
90 2012-03-19 00:32:29 <BlueMatt> what are you smoking?
91 2012-03-19 00:32:36 <BlueMatt> yea, but what if I want to fix a bug
92 2012-03-19 00:32:43 <BlueMatt> am I not allowed to say "Ive got this one"?
93 2012-03-19 00:32:57 <Diablo-D3> then fix it and in the commit log "closes #xxxxx"
94 2012-03-19 00:33:03 <Diablo-D3> when gavin merges it, it'll close.
95 2012-03-19 00:33:15 <BlueMatt> not unless Im a commiter, I think
96 2012-03-19 00:33:23 <Diablo-D3> nope, it'll import the close.
97 2012-03-19 00:33:27 <BlueMatt> because I know ive committed bugs that say closes #xxx and it didnt close
98 2012-03-19 00:33:41 <Diablo-D3> Ive seen bugs that did it.
99 2012-03-19 00:33:42 <freewil> BlueMatt, even if you arent a member of the project, the issue page will have a reference to your commit in your own repo

101 2012-03-19 00:33:57 <BlueMatt> freewil: that is != closing the bug
102 2012-03-19 00:34:02 <BlueMatt> but I dont care if it closes the bg
103 2012-03-19 00:34:12 <freewil> BlueMatt, and then when it merges it gets closed automatically
104 2012-03-19 00:34:22 <BlueMatt> not for me, at least
105 2012-03-19 00:34:25 <freewil> but you have to use the KW "closes or fixes" or something
106 2012-03-19 00:34:38 <freewil> like "fixed shit - Fixes #1"
107 2012-03-19 00:35:13 <BlueMatt> ok, then can I ask why we never use milestones (usually)?
108 2012-03-19 00:35:25 <Diablo-D3> habit
109 2012-03-19 00:35:27 <BlueMatt> and can I ask that github allow people to get assigned who arent pushers?

111 2012-03-19 00:35:49 <BlueMatt> or atleast allow people to say "this is a feature request" without making devs waste their time tagging shit
112 2012-03-19 00:35:51 <BlueMatt> that is just stupid
113 2012-03-19 00:35:55 <Diablo-D3> gavin should enforce git flow usage, imo
114 2012-03-19 00:36:05 <deoxxa> git-flow ftw
115 2012-03-19 00:36:09 <BlueMatt> how is that in any way related to the toipc at hand?

117 2012-03-19 00:36:58 <BlueMatt> mmm, and does it sync that info with git bugs?

152 2012-03-19 00:49:57 <phantomcircuit> i'd think 0x00 or random

167 2012-03-19 00:54:05 <phantomcircuit> my personal favorite is
168 2012-03-19 00:54:11 <phantomcircuit> write out the length of the padding
169 2012-03-19 00:54:17 <phantomcircuit> then write out the padding as 0x00

204 2012-03-19 01:12:43 <BlueMatt> and if we do pad mkeys, dont fix 933, do we?
205 2012-03-19 01:13:06 <jrmithdobbs> forever and ever? there will never ever be a reason to change ciphers/keysize for the wallet crypto?
206 2012-03-19 01:13:19 <jrmithdobbs> or have multiple options for it?
207 2012-03-19 01:13:58 <jrmithdobbs> you're right so long as it stays aes256 though
208 2012-03-19 01:14:02 <jrmithdobbs> key will always be 32 bytes
209 2012-03-19 01:14:24 <BlueMatt> then you can easily increment the nDerivationMethod or smth
210 2012-03-19 01:14:46 <BlueMatt> as long as nDerivationMethod = EVP_sha512, then yea it is 32 bytes

212 2012-03-19 01:15:10 <sipa> hmm, padding the encryption of the master key is actually even worse
213 2012-03-19 01:15:15 <sipa> as a leak
214 2012-03-19 01:15:30 <sipa> because an attacker doesn't even need to check any wallet key at all anymore
215 2012-03-19 01:15:37 <BlueMatt> yep
216 2012-03-19 01:15:39 <sipa> (though again, we don't rely on that for security)
217 2012-03-19 01:15:47 <BlueMatt> yea, but its nice to have
218 2012-03-19 01:16:16 <jrmithdobbs> sipa: i think a 16 byte multiple is a fine req for keysize, even if something that isn't ends up being used can just manually pad with random data
219 2012-03-19 01:17:25 <jrmithdobbs> (it also holds true for most non-toy ciphers anyways)
220 2012-03-19 01:18:22 <BlueMatt> Id say, add a comment above nDerivationMethod that says it can be used as either nDerivationMethod or nEncryptionMethod and say that nDerivationMethod == 0 means AES... and 32-byte mkey and sha512, etc, etc
221 2012-03-19 01:18:28 <BlueMatt> then you are safe
222 2012-03-19 01:18:47 <sipa> BlueMatt: i'm still going to keep CCrypter::Encrypt/Decrypt have a padding that defaults to true; people may use it for other things than keys as well
223 2012-03-19 01:18:56 <BlueMatt> thats fine
224 2012-03-19 01:20:22 <sipa> seems to work

246 2012-03-19 02:37:34 <Joric> does reference client send change back to the source address? how does it choose the return address?
247 2012-03-19 02:37:58 <sipa> simple: the next address is used
248 2012-03-19 02:38:06 <sipa> from the key pool
249 2012-03-19 02:38:26 <sipa> it never sends back to the source address, unless the key pool is empty
250 2012-03-19 02:38:41 <BlueMatt> no, it never sends back to the source address
251 2012-03-19 02:38:46 <BlueMatt> the keypool cant be empty at send time
252 2012-03-19 02:38:53 <sipa> oh, of course

254 2012-03-19 02:40:43 <Joric> so basically almost every transaction you increase a number of addresses in the blockchain
255 2012-03-19 02:40:53 <Joric> doesn't seem very rational
256 2012-03-19 02:41:10 <sipa> a new address in the blockchain doesn't use more space than an old one
257 2012-03-19 02:42:38 <BlueMatt> bugs blockchain.info, but doesnt bug any regular bitcoin use...
258 2012-03-19 02:43:18 <Joric> yeah index gets bigger and bigger all the time
259 2012-03-19 02:43:26 <BlueMatt> that is from txes, not from addresses
260 2012-03-19 02:43:43 <sipa> there is no address index anywhere in the bitcoin core
261 2012-03-19 02:43:49 <sipa> nor should there be
262 2012-03-19 02:44:06 <sipa> (it could be useful in some cases, but optional)

273 2012-03-19 02:54:22 <BlueMatt> gmaxwell: have a minute and a half to ack 950 and 948, also what do you think needs to go in 0.6?
274 2012-03-19 02:55:01 <luke-jr> pulls pending for 0.6 final: 947, 946, 936, 928, and it'd be nice to see 931 in
275 2012-03-19 02:55:15 <BlueMatt> oh, yea and 947
276 2012-03-19 02:55:22 <sipa> 947 probably doesn't harm, though it hardly helps anyway

279 2012-03-19 02:55:52 <sipa> when was getmemorypool introduced?
280 2012-03-19 02:55:58 <BlueMatt> nack on 936 for 0.6, seriously its not a bugfix, its a new feature, there is no reason to add it to 0.6...
281 2012-03-19 02:56:03 <luke-jr> sipa: 0.5; the BIP was written to be compatible
282 2012-03-19 02:56:10 <BlueMatt> 928, whatever
283 2012-03-19 02:56:29 <BlueMatt> 931 whatever
284 2012-03-19 02:56:41 <sipa> indeed, 936 for 0.7 looks fine
285 2012-03-19 02:56:56 <sipa> (which hopefully doesn't take as long as 0.6)
286 2012-03-19 02:57:33 <sipa> 928 can go in 0.6 if wumpus acks it
287 2012-03-19 02:58:03 <luke-jr> sipa: "coinbaseflags" added during 0.6 isn't compatible, and was replaced by "coinbaseaux" early on - the bitcoind code just hasn't been fixed for it yet
288 2012-03-19 02:58:20 <sipa> compatible with what?
289 2012-03-19 02:58:23 <luke-jr> the BIP
290 2012-03-19 02:58:40 <BlueMatt> how much discussion of the bip has there been on the mailing list?

296 2012-03-19 03:00:11 <sipa> gmaxwell: i merged with loadblocks and did an import of a previous testnet blk0001.dat file, which causes some reorganisations
297 2012-03-19 03:00:19 <sipa> gmaxwell: i didn't test that it actually solves the issue, though
298 2012-03-19 03:01:03 <BlueMatt> I thought you said you tested it with mcorlett
299 2012-03-19 03:01:15 <gmaxwell> Are we planning on cutting another 0.6 rc?
300 2012-03-19 03:01:34 <luke-jr> IMO, final should always be a RC renamed.
301 2012-03-19 03:01:41 <luke-jr> so any changes post-rc4 should mean a rc5
302 2012-03-19 03:01:58 <sipa> BlueMatt: that was #930
303 2012-03-19 03:02:01 <luke-jr> and 946 is really essential to another release
304 2012-03-19 03:02:10 <luke-jr> since without it you get the security issues of pre-0.5.3.1
305 2012-03-19 03:02:26 <gmaxwell> luke-jr: generally I'd be okay with pulling things like translations without another RC... these changes are far beyond that whic his why I was asking.

535 2012-03-19 10:50:39 * Eliel wonders if ignoring blocks received from nodes that don't forward you (valid) transactions would help with discouraging mining without transactions.
536 2012-03-19 10:51:10 slothbag has joined
537 2012-03-19 10:52:21 <sipa> Eliel: then they will hide behind some normal full nodes
538 2012-03-19 10:52:54 <Eliel> sipa: true, needs to be the whole network doing that for it to work.
539 2012-03-19 10:53:31 <Eliel> so, not a short term fix, this one.

541 2012-03-19 10:54:36 <Eliel> but basically, my idea was that if full nodes can somehow identify each other, then they can ignore blocks from nodes that aren't full nodes.
542 2012-03-19 10:55:52 <Eliel> feels like something to this effect would be worth doing, even if it'll take a long while until it's widespread enough

570 2012-03-19 11:22:40 <sipa> in the coinbase transaction
571 2012-03-19 11:23:07 <t7> to send a transaction i need a public and private key?
572 2012-03-19 11:23:30 <t7> i mean i need my own public and private key and the recipients public key
573 2012-03-19 11:23:38 <t7> is that correct?
574 2012-03-19 11:23:42 <sipa> to send a transaction tou need the public key (or its hash) of the recipient
575 2012-03-19 11:24:01 <sipa> and you need the private key of the addresses the input coins you want to use for that were previously sent to
576 2012-03-19 11:24:12 <sipa> (an address, for now, is a hash of a public key)

583 2012-03-19 11:27:03 <t7> wont it keep growing?
584 2012-03-19 11:27:35 <sipa> there's no absolute requirement that those keys are kept after their corresponding transactions are spent
585 2012-03-19 11:27:58 <sipa> that's just an implementation issue (and safety net, in case someone sends more coins to those addresses without asking you)
586 2012-03-19 11:28:50 <t7> im getting confused with addresses and coins
587 2012-03-19 11:29:09 <sipa> an address is the hash of a public key

595 2012-03-19 11:30:40 <sipa> yes
596 2012-03-19 11:31:04 <sipa> a transaction can consume multiple coins, and can produce multiple new coins; the only requirement is that the sum of the output values is not more than the sum of the input values

602 2012-03-19 11:34:35 <sipa> tomoj: it's not used anywhere; and addr_from is supposed to be the address you are listening on, not the one you are connecting from
603 2012-03-19 11:34:48 <sipa> if you're not listening, put 0.0.0.0:0 there

611 2012-03-19 11:56:34 <tomoj> should 0.6 clients connect only to testnet, assuming they have no coins to worry about losing?
612 2012-03-19 11:56:54 <tomoj> I mean, assuming no coins, should they _not_ connect to realnet?
613 2012-03-19 11:57:24 <sipa> it connects to testnet if it is instructed to
614 2012-03-19 11:58:46 <tomoj> right.. I mean should one connect 0.6 only to testnet until it is stable? can it damage the real network to have people using bleeding edge clients?
615 2012-03-19 11:59:42 <sipa> there's no problem in running a release candidate if you're willing to test, even on the real network
616 2012-03-19 11:59:50 <tomoj> great
617 2012-03-19 12:00:11 <sipa> but be aware there can always be bugs in it that - who knows - delete your wallet file, make your computer explode, ...

632 2012-03-19 12:16:57 <sipa> also, look a bit further back: there are really not that many 1 tx blocks

647 2012-03-19 12:24:21 <jeremias> testnet blockexplorer shows only 48188 blocks
648 2012-03-19 12:24:26 <jeremias> fffuuuuuuuu
649 2012-03-19 12:24:37 <sipa> i can put my online if you like
650 2012-03-19 12:25:34 <jeremias> testnet bitcoin daemon?
651 2012-03-19 12:25:55 <jeremias> it would be very beneficial to developers to have some kind of public testnet daemon running somewhere all the time
652 2012-03-19 12:26:16 <jeremias> and people could connect to it with JSON-RPC
653 2012-03-19 12:26:45 <sipa> i mean, i can upload my testnet blockchain (which is fully valid on 0.6.0rc4) somewhere
654 2012-03-19 12:26:50 <jeremias> hosting the testnet blockchain would be beneficial as well
655 2012-03-19 12:27:01 <jeremias> sipa: yeah, that would be great
656 2012-03-19 12:27:12 <jeremias> although it seems to be downloading it pretty fast

660 2012-03-19 12:32:22 <jeremias> sipa: thanks! I really appreciate it

831 2012-03-19 15:55:50 <sipa> I don't see that happening any time soon.
832 2012-03-19 15:56:00 <sipa> Who knows, of course :)
833 2012-03-19 15:56:50 <ternit> If that ever happened would the financial regulators get involved ?
834 2012-03-19 15:57:10 <ternit> or would they have no regulatory power against bitcoin?
835 2012-03-19 15:57:31 <sipa> they have regulatory power against cash

871 2012-03-19 16:18:53 * BlueMatt strongly believes not including 950 in 0.6 is the wrong thing to do, bu tok
872 2012-03-19 16:18:59 <BlueMatt> but ok
873 2012-03-19 16:19:03 <imsaguy2> no
874 2012-03-19 16:19:25 <imsaguy2> I upgraded from .5.3
875 2012-03-19 16:20:28 <sipa> imsaguy2: the thing is, i can't even load the database
876 2012-03-19 16:20:31 <sipa> you sent me
877 2012-03-19 16:20:43 <imsaguy2> well, it worked before the update
878 2012-03-19 16:21:08 <luke-jr> BlueMatt: I didn't mean to imply 950 (or any other pull) *shouldn't* be pulled; I was just tracking some
879 2012-03-19 16:21:29 <BlueMatt> I wasnt saying otherwise, I was just commenting re: gavinandresen's comments on the pull
880 2012-03-19 16:22:02 <gavinandresen> BlueMatt: I'm not convinced 950 has had sufficient testing
881 2012-03-19 16:22:09 <luke-jr> BlueMatt: btw, is CBlockStore more or less ready for pulling as soon as 0.6.0 final is out? or still needs some more something?
882 2012-03-19 16:22:33 <BlueMatt> luke-jr: Id like to get more eyeballs on it, but its more or less ready
883 2012-03-19 16:22:41 <luke-jr> (it's going to force rebasing stuff, and I'd rather get it over with sooner rather than later)
884 2012-03-19 16:22:57 <BlueMatt> gavinandresen: it needs wallet min_version incremented, but other than that, it works just fine...its such a simple pull anyway
885 2012-03-19 16:22:59 <luke-jr> yeah, and the earlier pulled the more testing it'll get
886 2012-03-19 16:23:05 <BlueMatt> true
887 2012-03-19 16:23:47 <sipa> BlueMatt: gavinandresen wondered whether it would load old encrypted wallets at all; originally, it didn't, it seems
888 2012-03-19 16:24:15 <gmaxwell> I'm unhappy with frequently breaking wallet backwards compatiblity.
889 2012-03-19 16:24:21 <gavinandresen> me too
890 2012-03-19 16:24:28 <sipa> see my comment on the pull req
891 2012-03-19 16:24:37 <gmaxwell> (doing so discourages people from testing, as they can't go back)
892 2012-03-19 16:24:40 <BlueMatt> sipa: it wont, it will always say passphrase incorrect...
893 2012-03-19 16:24:51 <gavinandresen> compressed keys will be a big enough benefit that I think the benefits outweigh the costs.
894 2012-03-19 16:24:55 <luke-jr> gmaxwell: IMO, it should be fine so long as it's only breaking non-final releases
895 2012-03-19 16:24:55 <sipa> BlueMatt: update
896 2012-03-19 16:24:56 <BlueMatt> so Id rather it say, wrong version, than passphrase incorrect
897 2012-03-19 16:25:56 <gavinandresen> not padding keys adds a small constant multiple to the work an attacker has to do, which I think is a very marginal benefit
898 2012-03-19 16:26:09 <jm9000> BlueMatt: Had a chance to look at that crash issue for 0.6.0 with the block chain I uploaded?
899 2012-03-19 16:26:38 <sipa> imsaguy2: 0.5.3, right, not an rc of that?
900 2012-03-19 16:26:45 <imsaguy2> yeah, straight .5.3
901 2012-03-19 16:27:51 <BlueMatt> sipa: i checked like 10 minutes ago, have you changed it since?
902 2012-03-19 16:27:51 <BlueMatt> gmaxwell: I agree, thats why i want to see 950 in 0.6, since that way we dont have to break wallets again in 0.7
903 2012-03-19 16:28:06 <gavinandresen> gmaxwell: have you tested CAddrMan? I've been re-testing it this morning; I'm concerned about 'addr' DoS, and am thinking of pulling it for 0.6
904 2012-03-19 16:28:14 <sipa> BlueMatt: two hours ago
905 2012-03-19 16:28:18 <midnightmagic> gavinandresen: is the method Matt used to trigger the bug going to be made available as well somewhere? I got all excited when I saw the words full disclosure from your twitter account. :)
906 2012-03-19 16:28:19 <BlueMatt> jm9000: sadly, not I hope to have some time today...
907 2012-03-19 16:28:29 <BlueMatt> sipa: I tested it way later than that
908 2012-03-19 16:28:52 <sipa> BlueMatt: ok, thanks; i'll retest it again
909 2012-03-19 16:29:03 <gmaxwell> gavinandresen: I've tested it. Not in a while, I think when I repulled for the BIP16 date move I dropped that patch on all my nodes.
910 2012-03-19 16:29:06 <luke-jr> gavinandresen: I've tested CAddrMan multiple times, and there are unresolved crash/addr.dat-corruption cases :/

918 2012-03-19 16:31:06 <sipa> i'll run it on my miner

927 2012-03-19 16:32:47 <sipa> luke-jr: ok
928 2012-03-19 16:32:55 <BlueMatt> sipa: afaict it loads old wallets no problem, but loading new wallets after encrypting with it (or I would assume changing passphrase) kills old node versions
929 2012-03-19 16:32:55 <BlueMatt> so I would say increment min_version and pull
930 2012-03-19 16:32:56 <BlueMatt> gavinandresen: its actually quite a major increase in work for attackers...it goes from impossibly hard to ridiculously impossibly hard

956 2012-03-19 16:39:41 <t7> is difficulty just the number the hash has to be under ?

994 2012-03-19 16:57:18 <luke-jr> is anyone else worried that these progress bar rebels will keep using vulnerable versions for the p.bar?
995 2012-03-19 16:58:05 <gmaxwell> luke-jr: No.
996 2012-03-19 16:58:28 <gmaxwell> luke-jr: Moreover, it's not like this is a risk to _other_ users.

1000 2012-03-19 16:59:39 <midnightmagic> +12%. jesus.
1001 2012-03-19 17:00:00 <sipa> another one like that and we break the record
1002 2012-03-19 17:00:46 <midnightmagic> that's going to overtake my mining hashrate growth again soon, and without a corresponding increase in price.
1003 2012-03-19 17:01:05 <midnightmagic> the squeeze is coming again.
1004 2012-03-19 17:01:38 <luke-jr> midnightmagic: wanna go in on a BFL Rig? :p
1005 2012-03-19 17:01:59 <midnightmagic> lol maybe!
1006 2012-03-19 17:02:36 <midnightmagic> you seem to be able to get early access to normal cards, so perhaps you can get reasonable access to a rig before the rewards halves.. ha ha

1016 2012-03-19 17:15:34 <copumpkin> is there an RPC call to monitor changes to a specific address (that doesn't necessarily belong to you)?

1021 2012-03-19 17:18:49 <copumpkin> luke-jr: is there a good solution to getting notified about payments to addresses that isn't just polling periodically or writing your own client?
1022 2012-03-19 17:19:08 <midnightmagic> copumpkin: i.. think there might be a couple monitoring patches that were done a really long time ago.. either monitorreceived or.. blocknotify?
1023 2012-03-19 17:19:36 <midnightmagic> check gavin's feature branches. i forget now how far they go, but at the very least they're against old versions.
1024 2012-03-19 17:19:37 <luke-jr> copumpkin: no
1025 2012-03-19 17:20:10 <luke-jr> if you can wait for 1 confirm, blocknotify could be used to poll only on new blocks
1026 2012-03-19 17:20:38 <sipa> ok, miner node running with addrman, debug_addrman and valgrind
1027 2012-03-19 17:20:42 <sipa> let's wait a day
1028 2012-03-19 17:22:29 <copumpkin> luke-jr: I guess I could live with that. Is there an RPC call for asking what's in a given address?
1029 2012-03-19 17:22:58 <luke-jr> copumpkin: 'help'
1030 2012-03-19 17:23:55 <[Tycho]> What happened with the last difficulty change ?
1031 2012-03-19 17:24:18 <copumpkin> luke-jr: I looked in there, but getreceivedbyaddress says it returns 0 for external addresses and I couldn't see something that looked more promising
1032 2012-03-19 17:24:31 <luke-jr> copumpkin: oh, for external address it's impossible
1033 2012-03-19 17:25:01 <copumpkin> by design? it seems like that'd be fairly straightforward to ask to the database
1034 2012-03-19 17:25:03 <sipa> copumpkin: that would require keeping a table of all address balances
1035 2012-03-19 17:25:07 <copumpkin> oh
1036 2012-03-19 17:25:14 <luke-jr> copumpkin: there is no such database in bitcoind
1037 2012-03-19 17:25:20 <copumpkin> ah, okay
1038 2012-03-19 17:25:22 <sipa> that's not impossible, but unless for very specific purposes, useless
1039 2012-03-19 17:25:33 <copumpkin> so I guess blockchain.info API it is :)
1040 2012-03-19 17:25:45 <luke-jr> copumpkin: if you have the private key at all, you can import it then encrypt the wallet and throw away the passphrase
1041 2012-03-19 17:25:47 <copumpkin> or I could maintain that table myself
1042 2012-03-19 17:26:14 <copumpkin> nah, this is for a service that needs to monitor addresses it explicitly does not have the key to (since I don't want to deal with other people's money)
1043 2012-03-19 17:26:41 <copumpkin> anyway, that gets me started, I think
1044 2012-03-19 17:26:46 <luke-jr> copumpkin: probably not hard to hack bitcoind for it
1045 2012-03-19 17:26:56 <luke-jr> just return true from IsMine on every key or smth

1058 2012-03-19 17:37:46 <bluefirecorp> so it's both?
1059 2012-03-19 17:37:51 <bluefirecorp> Both are required, all 1.3 gb/
1060 2012-03-19 17:38:03 <sipa> the actual blockchain is in blk0001.dat
1061 2012-03-19 17:38:15 <gmaxwell> blk0001.dat is the chain itself, blkindex.dat is the index to the data in the chain.

1173 2012-03-19 20:14:59 <gmaxwell> rebroad: It's the prefix appeneded to message signing in order to make sure that someone can't trick you into signing a transaction or the like.
1174 2012-03-19 20:15:12 <sipa> rebroad: it's to make sure that the hash you're signing when using the sign message feature, will never match that of any other data structure like a transaction

1180 2012-03-19 20:16:33 <Samuel> sipa: it s a notification that their has been a new transaction since last time you checked.
1181 2012-03-19 20:16:54 <sipa> i see
1182 2012-03-19 20:16:54 <Samuel> sipa: Not sure if i like the shape though, maybe a circle witha nember inside
1183 2012-03-19 20:17:20 <sipa> iirc there was an earlier design that also had some way for showing this
1184 2012-03-19 20:17:33 <tcatm> Samuel: Can you provide PNGs for the buttons? (both states and maybe a hover state)
1185 2012-03-19 20:17:39 <sipa> that i found more intuitive (or maybe it was just more like something i've seen before)
1186 2012-03-19 20:18:11 <tcatm> Samuel: ..including all shadows but with transparent background.
1187 2012-03-19 20:18:42 <Samuel> tcatm: Yeah, ok. Might take a bit to do
1188 2012-03-19 20:18:58 <Samuel> Icons too?
1189 2012-03-19 20:19:04 <tcatm> Yes.
1190 2012-03-19 20:19:08 <Samuel> ok
1191 2012-03-19 20:19:15 <rebroad> gmaxwell, is it part of the COINBASE_FLAGS? I'm trying to work out where those are defined... are they used for voting?
1192 2012-03-19 20:19:33 <sipa> rebroad: message signing has nothing to do with transactions or blocks or mining
1193 2012-03-19 20:20:38 <gmaxwell> And coinbase flags _ARE NOT VOTING_
1194 2012-03-19 20:23:42 <sipa> gmaxwell: it'll be hard for people to forget that term, i'm afraid
1195 2012-03-19 20:24:14 <Samuel> tcatm: Do you want the text and icon actually included on the image? (Will probably turn out best this way)
1196 2012-03-19 20:25:48 <sipa> I wouldn't include the text.
1197 2012-03-19 20:26:39 <sipa> Unless you would like to make new images for all translated languages.
1198 2012-03-19 20:26:51 <Samuel> Well it might be hard to add subtle effects like drop-shadow in code, where as in Photoshop its easy
1199 2012-03-19 20:27:42 <gmaxwell> sipa: we're not going to be able to use them in the future if people keep thinking that. :(
1200 2012-03-19 20:27:58 <tcatm> Samuel: Nope, only icon.
1201 2012-03-19 20:28:25 <Samuel> ok
1202 2012-03-19 20:28:39 <tcatm> Samuel: Also make the buttons and icons separate files.
1203 2012-03-19 20:29:17 <Samuel> Yeah, thats what I was thinking, You don't want text as separate images do you?
1204 2012-03-19 20:29:27 <Samuel> Because the text has effects applied in it
1205 2012-03-19 20:30:26 <tcatm> We can add those effects once we have figured out how to do that with Qt.
1206 2012-03-19 20:31:56 <egecko> can anyone think of why the bitcoin json-rpc would return addresses/accounts/other data when it is locked down with an rpc username & password and the request has invalid credentials (in particular, an empty password being sent passed in)?
1207 2012-03-19 20:32:39 <gmaxwell> egecko: what version?
1208 2012-03-19 20:33:03 <sipa> also, how is it locked down?
1209 2012-03-19 20:33:09 <gmaxwell> egecko: in particular, the most recent versions shouldn't even let an empty password be used even if you specify oneâ so that behavior shouldn't be possible even via misconfiguration.
1210 2012-03-19 20:33:30 <egecko> server is runing 0.5.2
1211 2012-03-19 20:33:34 <egecko> client is custom
1212 2012-03-19 20:33:48 <egecko> server is locked down via the config file's rpc username and password settings
1213 2012-03-19 20:33:49 <gmaxwell> okay, thats not new enough to completely disallow empty passwords I think.
1214 2012-03-19 20:34:07 <gmaxwell> egecko: does it still work when you make the password something else?
1215 2012-03-19 20:34:13 <egecko> lemme try
1216 2012-03-19 20:34:17 <gmaxwell> and have you restarted it since you set those things? the config file is only read on startup.

1221 2012-03-19 20:36:44 <gmaxwell> then your password is the empty string.
1222 2012-03-19 20:36:57 <egecko> nope
1223 2012-03-19 20:37:06 <egecko> its set to a non-empty value
1224 2012-03-19 20:37:12 <sipa> how is it set?
1225 2012-03-19 20:37:15 <egecko> on the server side, but it is passed in as empty from the client
1226 2012-03-19 20:37:26 <egecko> its in the bitcoin config file
1227 2012-03-19 20:37:34 <sipa> rpcpassword=<password> ?
1228 2012-03-19 20:37:44 <egecko> i believe so
1229 2012-03-19 20:37:47 <sipa> exactly that way? (without the <> and ? charachters)
1230 2012-03-19 20:37:55 <gmaxwell> Don't believe. Check. And does it have any funky characters?
1231 2012-03-19 20:38:10 <egecko> its all pure alphanumeric
1232 2012-03-19 20:38:51 <sipa> can you copy-paste the line that sets it (change the password itself though)

1239 2012-03-19 20:41:37 <egecko> it is in a custom directory that also stores the wallet
1240 2012-03-19 20:42:15 <egecko> and its all started via shell script when this linux box starts up
1241 2012-03-19 20:42:29 <gmaxwell> I suspect it's manging to read the wrong configuration file.
1242 2012-03-19 20:42:37 <sipa> what command line?
1243 2012-03-19 20:42:46 <sipa> to start bitcoind from the script?
1244 2012-03-19 20:42:49 <egecko> even though there's one a single bitcoin.conf on the box?
1245 2012-03-19 20:43:30 <egecko> $BITCOIN -daemon -server -datadir=/path/to/custom/dir
1246 2012-03-19 20:43:54 <sipa> and /path/to/custom/dir/bitcoin.conf is the config file?
1247 2012-03-19 20:44:07 <gmaxwell> well, -server is probably enough to make it support rpc without a config file.
1248 2012-03-19 20:44:12 <egecko> that path contains the wallet and bitcoin.conf file
1249 2012-03-19 20:44:52 <sipa> afaik it was never possible to run bitcoind without setting an rpcpassword
1250 2012-03-19 20:45:33 <gmaxwell> sipa: hmâ it was possible to run it setting either a user or a password. but yea, even that doesn't fit these facts.

1260 2012-03-19 20:53:10 <egecko> ok, so what i just tried was to remove "-server" from the parameters, and now it does not accept either the legit password or an empty string
1261 2012-03-19 20:53:37 <sipa> wow, really?

1265 2012-03-19 20:56:21 <egecko> no, it did accept the legit password
1266 2012-03-19 20:57:18 <egecko> thats how i stumbled on this... i had logged in through the client im working on, then "logged out" which clears out the stored password and then i was testing what happens when you attempt to connect w/o a password, and suddenly i was pulling a whole slew of data that i should not have been able to
1267 2012-03-19 20:57:44 <egecko> does the bitcoin daemon allow you to keep connections alive?
1268 2012-03-19 20:57:58 <egecko> perhaps its because the previous connection was still alive?

1295 2012-03-19 21:27:04 <jm9000> Yeah, kind of figured that not much real discussion was on the forum. I did find a post but it was dead.
1296 2012-03-19 21:27:26 <sipa> there are a few prerequisites first, such as disconnecting the wallet db environnement from the block chain db environnement
1297 2012-03-19 21:27:45 <sipa> or moving away from bdb entirely for wallets
1298 2012-03-19 21:27:57 * BlueMatt votes for #2
1299 2012-03-19 21:28:37 <sipa> and it's "environment" in english, right?
1300 2012-03-19 21:28:49 * sipa confuses with french
1301 2012-03-19 21:29:05 <BlueMatt> yea, environment works
1302 2012-03-19 21:29:09 <BlueMatt> it is DbEnv
1303 2012-03-19 21:29:11 <BlueMatt> iirc
1304 2012-03-19 21:29:16 <BlueMatt> Env-ironment
1305 2012-03-19 21:29:29 <sipa> yes; i mean as in opposed to environnement
1306 2012-03-19 21:29:38 <BlueMatt> no, 1st is right
1307 2012-03-19 21:30:03 <Eliel> linux systems really need the possibility to run one full node and separate wallet software for each user simultaneously :)
1308 2012-03-19 21:30:15 <sipa> Eliel: yes, that would be nice
1309 2012-03-19 21:30:22 <sipa> i'd even like to see that over network
1310 2012-03-19 21:30:35 <Eliel> that's a natural extension, yes.
1311 2012-03-19 21:30:55 * BlueMatt would like to see CBlockStore accessible over network
1312 2012-03-19 21:31:02 <sipa> yeah :)
1313 2012-03-19 21:31:04 <BlueMatt> which should work pretty nicely
1314 2012-03-19 21:31:52 <Eliel> I currently have an extra user account with encrypted home folder just for my savings wallet and it's kind of a chore to either wait for the client to catch up or manually copy the blockchain over each time.

1336 2012-03-19 21:39:42 <egecko> any thought been given to breaking up the historical data so every box doesn't have to keep petabytes of data around in 20 years? maybe have some kind of referral to the network if a referenced transaction isn't found? that way its up to the miners if they want to store an arbitrary amount of time worth of transactions and it provides a way to identify master nodes that do contain the entire transaction history

1375 2012-03-19 22:09:48 <Matt_von_Mises> Since the conflicting transaction would propagate the network quickly enough.
1376 2012-03-19 22:10:35 <Matt_von_Mises> How long would it take to be sure there are no conflicting transactions?
1377 2012-03-19 22:10:51 <sipa> luke-jr: iirc it was reproducible when running test_bitcoin
1378 2012-03-19 22:11:12 <gmaxwell> Matt_von_Mises: ... conflicting transactions _dont_ propagate through the network.. not unless they were released before the other side was completely propagated.
1379 2012-03-19 22:11:33 <luke-jr> Matt_von_Mises: conflicting transactions don't NEED to propagate the network period
1380 2012-03-19 22:12:00 <Matt_von_Mises> But you want the double spend to yourself to propagate to the miners right?
1381 2012-03-19 22:12:07 <luke-jr> Matt_von_Mises: unless you are the miner.
1382 2012-03-19 22:12:15 <luke-jr> Matt_von_Mises: and you can always connect directly to the miners
1383 2012-03-19 22:12:44 <Matt_von_Mises> Could you send the transaction to yourself to the miners after you sent the fake transaction directly to the merchant?
1384 2012-03-19 22:12:56 <Matt_von_Mises> Something like that would work?
1385 2012-03-19 22:13:01 <luke-jr> Matt_von_Mises: it could.
1386 2012-03-19 22:13:10 <gmaxwell> Matt_von_Mises: the attacker could connect to a lot of nodes propagate txn A to all nodes they hit except deepbit, B to deepbit a fraction of a second later. It would be very unlikely for anyone to hear the conflict unless they were also connected to that particular miner.
1387 2012-03-19 22:14:03 <luke-jr> sipa: I am unable to reproduce anything involving bn2mpi with test_bitcoin O.o;;
1388 2012-03-19 22:15:38 <Matt_von_Mises> Is there a way to modify the network characteristics to make 0 confirmation transactions safe without a third party?
1389 2012-03-19 22:15:50 <luke-jr> yes
1390 2012-03-19 22:16:05 <Matt_von_Mises> And I guess it would need majority participation.
1391 2012-03-19 22:16:19 <luke-jr> it wouldn't be completely safe, since the attacker can just mine his own block
1392 2012-03-19 22:16:27 <sipa> ?
1393 2012-03-19 22:16:30 <luke-jr> eg, with GPUMAX
1394 2012-03-19 22:16:35 <Matt_von_Mises> luke-jr: How would that work? By spreading bad transactions?
1395 2012-03-19 22:16:36 <gmaxwell> ... luke-jr meant to say no. I think.
1396 2012-03-19 22:16:46 <luke-jr> Matt_von_Mises: right
1397 2012-03-19 22:17:00 <luke-jr> if conflicts were relayed in some way, you could watch for them
1398 2012-03-19 22:17:13 <Matt_von_Mises> luke-jr: Mining your own block is impractical for an attack no?
1399 2012-03-19 22:17:18 <luke-jr> then you just need to worry about a rogue miner giving preference for a later conflict
1400 2012-03-19 22:17:22 <luke-jr> Matt_von_Mises: no
1401 2012-03-19 22:17:23 <gmaxwell> luke-jr: that isn't enough, because the conflict could still be mined without being relayed.
1402 2012-03-19 22:17:27 <Matt_von_Mises> Since you'd have to wait for your own block.
1403 2012-03-19 22:17:28 <gmaxwell> (or that)
1404 2012-03-19 22:17:43 <gmaxwell> Matt_von_Mises: no, you do the finney attack.
1405 2012-03-19 22:18:01 <Matt_von_Mises> "Matt_von_Mises: no, you do the finney attack." But you need to mine your own block.
1406 2012-03-19 22:18:20 <gmaxwell> Yes. So?
1407 2012-03-19 22:18:20 <Matt_von_Mises> Thats not as simple as pressing a button.
1408 2012-03-19 22:18:25 <gmaxwell> It almost is.
1409 2012-03-19 22:18:27 <sipa> Matt_von_Mises: for some here, it is
1410 2012-03-19 22:18:38 <sipa> and if you pay for it, it's not hard at all
1411 2012-03-19 22:18:38 <gmaxwell> (nor is a double spend of any kind)

1413 2012-03-19 22:19:31 <Matt_von_Mises> So you can get yourself a new valid block almost instantly?
1414 2012-03-19 22:19:34 <luke-jr> sipa: do you know what ver of OpenSSL you used?
1415 2012-03-19 22:19:48 <luke-jr> Matt_von_Mises: you don't need it instantly, just before anyone else
1416 2012-03-19 22:20:03 <luke-jr> Matt_von_Mises: and if you fail, nobody knows and you can keep trying
1417 2012-03-19 22:20:37 <Matt_von_Mises> It's designed to fail.
1418 2012-03-19 22:20:45 <Matt_von_Mises> Not everyone can generate the next block.
1419 2012-03-19 22:20:49 <Matt_von_Mises> Right?
1420 2012-03-19 22:20:56 <luke-jr> Matt_von_Mises: with GPUMAX, you can pay for it
1421 2012-03-19 22:21:07 <Matt_von_Mises> So you have to wait until you can get one in time to execute a scam
1422 2012-03-19 22:21:20 <Matt_von_Mises> And you need to be prepared to do this scam
1423 2012-03-19 22:21:29 <luke-jr> Matt_von_Mises: or wait until you have found the block, before starting the scam
1424 2012-03-19 22:22:05 <BlueMatt> you can safely accept 0 confirm txes if you are well peered with miners and dont see conflicts
1425 2012-03-19 22:22:10 <luke-jr> eg, don't broadcast your spend-to-merchant transaction until you have a conflciting block prepared
1426 2012-03-19 22:22:10 <BlueMatt> well, reasonably safely
1427 2012-03-19 22:22:16 <BlueMatt> after a certain period
1428 2012-03-19 22:22:25 <luke-jr> BlueMatt: GPUMAX
1429 2012-03-19 22:22:25 <Matt_von_Mises> GPUMAX allows you to buy mining power basically?
1430 2012-03-19 22:22:29 <luke-jr> Matt_von_Mises: yes
1431 2012-03-19 22:22:44 <BlueMatt> luke-jr: yea, thats why its only sane for eg. a few btc
1432 2012-03-19 22:22:58 <BlueMatt> more than that, there really is no way to safely accept 0-confirm txes
1433 2012-03-19 22:23:02 <BlueMatt> or even really 1-confirm txes

1436 2012-03-19 22:24:30 <Matt_von_Mises> Would it be a major problem?
1437 2012-03-19 22:24:47 <BlueMatt> depends on the volume

1443 2012-03-19 22:26:17 <gmaxwell> And if rolex store, does it have security cameras? Did they get a copy of the customer's ID?
1444 2012-03-19 22:26:38 <Matt_von_Mises> BitPay takes on this risk for 0.99%, is that at all sensible to pay 0.99% to guarantee payment assuming you trust BitPay?
1445 2012-03-19 22:27:09 <Matt_von_Mises> Or is it stupid, they might as well accept 0 confirmation payments?

1507 2012-03-19 23:32:52 <Eliel> Matt_von_Mises: that 2.99% thing is another product in itself :)
1508 2012-03-19 23:33:03 <Matt_von_Mises> They could even sell the ability to include fraudulent transactions into a block to scammers.

1546 2012-03-19 23:52:53 <Matt_von_Mises> THat would be more secure.
1547 2012-03-19 23:52:59 <sipa> it tries to
1548 2012-03-19 23:53:22 <Eliel> that is quite inconvenient if you're doing many transactions in a row.
1549 2012-03-19 23:53:26 <Matt_von_Mises> I seem to remember the last time I sent a transaction it didn't want a password.
1550 2012-03-19 23:53:39 <sipa> The GUI only unlocks as long as necessary to perform the given action.
1551 2012-03-19 23:53:45 <Matt_von_Mises> Well is the option available to people to enable wallet locking after transactions?
1552 2012-03-19 23:54:00 <Eliel> maybe a timer so it only remembers the password for 10 minutes after the last use or so.
1553 2012-03-19 23:54:15 <Matt_von_Mises> I think I was using an older software. I think the software with the old UI didn't use good encryption.
1554 2012-03-19 23:54:30 <sipa> The encryption never changed.
1555 2012-03-19 23:54:37 <sipa> The RPC interface is more flexible, as you need to give a timeout when unlocking it, and there is an explicit walletlock command.
1556 2012-03-19 23:54:54 <Matt_von_Mises> It shouldn't store the password on the computer storage, only memory.
1557 2012-03-19 23:55:03 <sipa> It never stores the password.

1560 2012-03-19 23:55:47 <Matt_von_Mises> Then it leaves the wallet unencrypted on the hard drive?
1561 2012-03-19 23:55:54 <sipa> No, never.
1562 2012-03-19 23:56:18 <sipa> On-disc decryption is not even implemented.
1563 2012-03-19 23:56:29 <Matt_von_Mises> I could swear I encrypted the wallet with the old version of the software, closed the software, came back later and made a transaction and it never asked me for the password!
1564 2012-03-19 23:56:47 <sipa> That sounds very implausible.
1565 2012-03-19 23:56:55 <Matt_von_Mises> Maybe I was dreaming. :-)
1566 2012-03-19 23:57:32 <Eliel> it's most plausible you dreamed the encrypting the wallet part, if so :)
1567 2012-03-19 23:57:43 <Matt_von_Mises> THe new UI is nicer looking but the layout is stupid.

1569 2012-03-19 23:58:07 <Matt_von_Mises> The transactions table doesn't give very good information
