15 2011-07-09 00:04:11 <justmoon> so when jeff was like "no alternative client has getwork" I was like ..... *obsess*
16 2011-07-09 00:04:26 <justmoon> then you were like: "oh nice getwork, but you don't have scripts"
17 2011-07-09 00:04:34 <BlueMatt> well that has been the missing feature
18 2011-07-09 00:04:40 <BlueMatt> that only original client had

27 2011-07-09 00:05:25 <BlueMatt> yea, offer would be better

72 2011-07-09 00:20:03 <justmoon> ahh, gotcha
73 2011-07-09 00:20:07 <groffer> to ensure that the coin has certain properties
74 2011-07-09 00:20:14 <justmoon> is that possible?
75 2011-07-09 00:20:32 <groffer> for example that it is spendable by a certain address
76 2011-07-09 00:20:43 <groffer> look for Solver in script.cpp
77 2011-07-09 00:20:46 <bd_> Since there are no unbounded loops (IIRC) in the signature scripts, you could in principle build an execution tree, then trace backwards from the successful leaves...

137 2011-07-09 00:51:49 <sipa> i mean looking at an output script, and searching for an input that makes it evaluate to true
138 2011-07-09 00:52:41 <justmoon> output script? do you mean an output stack or a scriptSig?
139 2011-07-09 00:53:08 <sipa> look at ascriptPubKey, search for scriptSig

145 2011-07-09 00:54:47 <justmoon> ok, and if the pubkey has a checksig it would have like a "signature here" placeholder in it's solution?

147 2011-07-09 00:55:25 <justmoon> would such a solver be useful for anything?
148 2011-07-09 00:55:28 <sipa> no, the real signature
149 2011-07-09 00:55:36 <sipa> probably not
150 2011-07-09 00:55:48 <sipa> but i think it is possible
151 2011-07-09 00:56:35 <justmoon> it would be kind of like, the client checking if there are any transactions that it can receive
152 2011-07-09 00:56:44 <sipa> indeed
153 2011-07-09 00:57:16 <justmoon> would be nice to be the only one running something like that, might grab a few a coins when somebody messes up a script ^^
154 2011-07-09 00:57:37 <sipa> some shortcut version that only checks feasibility would be nice
155 2011-07-09 00:57:56 <sipa> since signing is computationally expensive
156 2011-07-09 00:58:33 <sipa> maybe for somewhere in a few months

161 2011-07-09 01:00:20 <BlueMatt> you mean IsStandard-in-crypto style checking of txes but more general?
162 2011-07-09 01:00:28 <BlueMatt> <sipa> some shortcut version that only checks feasibility would be nice
163 2011-07-09 01:01:47 <justmoon> I think feasibility = can I spend it? solved = how can I spend it? mb..
164 2011-07-09 01:01:53 <justmoon> solver*
165 2011-07-09 01:02:56 <BlueMatt> well the hard part there is signing
166 2011-07-09 01:03:06 <BlueMatt> which Is a simple matter or skipping the Sign call
167 2011-07-09 01:04:38 <justmoon> BlueMatt, sipa, are we happy with the way the official clients chooses nodes to download blocks from or is that something we'd like to improve but haven't had time for?
168 2011-07-09 01:04:49 <justmoon> client*
169 2011-07-09 01:05:09 <BlueMatt> aside from maybe a better algorithm for anti-sybil stuff, the actual downloading is fine
170 2011-07-09 01:05:17 <BlueMatt> downloading doesnt matter, its connections that matter
171 2011-07-09 01:05:25 <BlueMatt> downloading does, and should come from all connected nodes
172 2011-07-09 01:05:45 <BlueMatt> but in terms of connections, a more general algo than "not in the same /24" would be nice
173 2011-07-09 01:05:54 <BlueMatt> just general ip diversity

178 2011-07-09 01:07:11 <justmoon> hmm, cause it's one of those areas where my clients still sucks (gets stuck when there's a bad node, etc.) and I'm not sure how exactly to do that properly
179 2011-07-09 01:07:33 <BlueMatt> bitcoind does it fairly properly
180 2011-07-09 01:07:38 <BlueMatt> try to get everything from everyone
181 2011-07-09 01:07:38 <justmoon> k
182 2011-07-09 01:07:55 <BlueMatt> though if a node keeps feeding you bs, you should drop them
183 2011-07-09 01:08:04 <BlueMatt> ie I have blockx when it doesnt
184 2011-07-09 01:08:09 <justmoon> but it won't request the same blocks from two nodes, will it? during the initial download?
185 2011-07-09 01:08:17 <BlueMatt> no
186 2011-07-09 01:08:24 <BlueMatt> it wont ever request the same block twice
187 2011-07-09 01:09:29 <OneTimePad> my debug log is over a gig on my windows machine. there any auto purging on that?

207 2011-07-09 01:12:36 <BlueMatt> justmoon: sorry, I havent spent too much time with the net code
208 2011-07-09 01:12:41 <sipa> maybe not enough
209 2011-07-09 01:12:50 <BlueMatt> didnt come up with wallet crypto ;)
210 2011-07-09 01:13:20 <BlueMatt> sipa: are you still concerned about those ooms?
211 2011-07-09 01:13:21 <sipa> as long as we dont have full unit tests
212 2011-07-09 01:13:25 <sipa> yes
213 2011-07-09 01:13:33 <justmoon> BlueMatt, just to be clear, that was a genuine thank you, you saved me a lot of time with that overview :)
214 2011-07-09 01:13:43 <justmoon> so no irony or anything like that
215 2011-07-09 01:13:46 <BlueMatt> justmoon: ok, np

223 2011-07-09 01:14:30 <OneTimePad> one more nub question. if i've got port forwarding already on, should i turn upnp off or does it not matter at that point?
224 2011-07-09 01:14:46 <BlueMatt> sipa: hmmm...well I really dont want to hold up release on that, esp when 0.4 will just be import/export, crypto, and minor stuff

232 2011-07-09 01:15:37 <OneTimePad> yeah, i understand its benefit but I installed 0.3.24 and it opened with it enabled, and it got to 8 connections and stopped. I normally have around 80

237 2011-07-09 01:19:05 <OneTimePad> 10 minutes when I did that. Another 5 minutes and it's bumped to 10 now. I was just worried when it stopped at the magic 8 number. Now that I've typed this, at 11. Disregard.

246 2011-07-09 01:26:27 <Marf> can version 1.5 still connect to the network?
247 2011-07-09 01:26:32 <BlueMatt> 0.5
248 2011-07-09 01:26:42 <BlueMatt> currently, pretty much everything is backward compatible
249 2011-07-09 01:26:53 <BlueMatt> how much is guaranteed 0.5 releases, aka 0.000001 versions
250 2011-07-09 01:26:54 <Marf> will it stay this way?
251 2011-07-09 01:27:13 <BlueMatt> obviously that is a priority, but you never know what will come up
252 2011-07-09 01:27:24 <BlueMatt> what cool features might be added, etc
253 2011-07-09 01:27:43 <Marf> ok

256 2011-07-09 01:28:13 <gmaxwell> 16:47 <@BlueMatt> ok, now Im legitimately starting to get concerned here...either people are shutting off bitcoin nodes en-masse and not restarting them
257 2011-07-09 01:28:35 <gmaxwell> ^ I'd pointed out before that there appeared to be some kind of attack going on against namecoin, might also be true for bitcoin.
258 2011-07-09 01:28:53 <gmaxwell> (thousands and thousands of namecoin nodes in russia showed up on IRC basically over night)
259 2011-07-09 01:28:54 <BlueMatt> well it happened too close to 0.3.24 release for it to be coincidence
260 2011-07-09 01:29:08 <BlueMatt> and its showing up as a decrease in 0.3.23 nodes available
261 2011-07-09 01:29:18 <BlueMatt> (and some 0.3.22) whereas other numbers are entirely unchanged

263 2011-07-09 01:29:50 <BlueMatt> could be any number of things though...
264 2011-07-09 01:30:19 <BlueMatt> but it is very disturbing that total listening on 8333 has dropped by almost half here
265 2011-07-09 01:30:40 <Marf> bitcoin popularity going down?
266 2011-07-09 01:30:59 <DontMindMe> What's new in 0.3.24 ? Is there a changelog anywhere? (Except bitcoin-wiki because it's not there yet)
267 2011-07-09 01:31:02 <BlueMatt> Marf: no
268 2011-07-09 01:31:07 <BlueMatt> network issues somewhere
269 2011-07-09 01:31:18 <BlueMatt> DontMindMe: the release announcements
270 2011-07-09 01:31:21 <luke-jr> BlueMatt: is it my fault for connecting to every node?
271 2011-07-09 01:31:36 <BlueMatt> luke-jr: unless you are making 100 connections to every node, cant be
272 2011-07-09 01:31:42 <luke-jr> ok
273 2011-07-09 01:31:47 <BlueMatt> not that Id advise that
274 2011-07-09 01:31:57 <DontMindMe> BlueMatt: ... obviously. I'm an idiot today. :)
275 2011-07-09 01:32:02 <BlueMatt> quite the opposite, but shouldnt be the problem
276 2011-07-09 01:32:11 <BlueMatt> luke-jr: ^

279 2011-07-09 01:33:03 <BlueMatt> invalid blocks?
280 2011-07-09 01:33:29 <gmaxwell> His pool had an impossibly long run of orphans.
281 2011-07-09 01:33:36 <BlueMatt> oh
282 2011-07-09 01:33:51 <BlueMatt> well better would be addnode deepbit, other pools, etc
283 2011-07-09 01:34:30 Wuked1 has joined
284 2011-07-09 01:35:02 <gmaxwell> Addnode doesn't do much.
285 2011-07-09 01:35:26 <BlueMatt> well if you addnode other big pools it should solve it
286 2011-07-09 01:35:27 <WakiMiko> with dnsseeding enabled by default now, is the -dns switch still needed for addnode and connect?
287 2011-07-09 01:35:35 storrgie has quit (Quit: Leaving)
288 2011-07-09 01:35:54 <gmaxwell> Though I swear I'll put up a patch that redoes the connection logic this weekend. I've got one, I just need to build a big enough testbed to validate it.
289 2011-07-09 01:36:21 <gmaxwell> BlueMatt: except addnode is one shot, so once they get disconnected (for whatever reason) they likely won't come back.
290 2011-07-09 01:36:33 <luke-jr> BlueMatt: DeepBit won't share node IPs
291 2011-07-09 01:36:45 <BlueMatt> gmaxwell: ok, well a proper addnode then
292 2011-07-09 01:36:57 <Wuked1> Hey Guys, I've been noticing an increasing number of "duplicate" shares being recored in my pool - I've grabbed the latest stable versions of pushpool and bitcoind - but the problem still seems to be there
293 2011-07-09 01:36:59 <BlueMatt> [Tycho]: and why not?
294 2011-07-09 01:37:11 <BlueMatt> luke-jr: well still, then add slush's node and whatever nodes you can find
295 2011-07-09 01:37:12 <luke-jr> Wuked1: merge my getwork_dedupe branch
296 2011-07-09 01:37:20 <Wuked1> I saw that luke-jr made a change in his branch : http://luke.dashjr.org/programs/bitcoin/w/bitcoind/luke-jr.git/commitdiff/02d87b3aa375810bcd63dcf72637e788a75fc7d4
297 2011-07-09 01:37:23 <luke-jr> Wuked1: and/or join Eligius ;)
298 2011-07-09 01:37:28 <vrs> http://privwiki.dreamhosters.com/wiki/Distributed_mining_pool_proposal <- hey, aren't these the "sub-bitcoin"-networks that have been floating around as an idea for some time?
299 2011-07-09 01:37:52 <Wuked1> luke-jr: should I merge your branch, or would I be better using your entire bitcoind install ?
300 2011-07-09 01:37:58 <luke-jr> is slush2's node public?
301 2011-07-09 01:38:11 <luke-jr> Wuked1: just merge it. my branches aren't generally made for use
302 2011-07-09 01:38:15 <luke-jr> I branch for merging
303 2011-07-09 01:38:32 <luke-jr> exception to my 'combo' branch which is what I actually use for my client (but not pool)
304 2011-07-09 01:38:43 <vrs> basically, small bitcoin-x-networks that are bootstrapped to the big network
305 2011-07-09 01:39:00 <BlueMatt> vrs: sort of
306 2011-07-09 01:39:05 <luke-jr> BlueMatt: I assume it's because it would make his nodes DDoS targets
307 2011-07-09 01:39:19 <luke-jr> and he doesn't trust me to keep it secret or smth
308 2011-07-09 01:39:25 <vrs> extend the distributed pool protocol to support intra-pool transactions and you have instant scalability
309 2011-07-09 01:39:40 <luke-jr> and/or he needs some kind of "one size fits all" policy

311 2011-07-09 01:40:22 <^1bitc0inplz> luke-jr: does your branch contain the patches you did to do generational payouts from your pool? I'm curious how you accomplished that.
312 2011-07-09 01:41:29 <vrs> hm, will i need a certain number of posts to answer in http://forum.bitcoin.org/index.php?topic=27216.0? I don't have an account yet
313 2011-07-09 01:41:34 <luke-jr> ^1bitc0inplz: that is the coinbaser branch
314 2011-07-09 01:41:53 <luke-jr> ^1bitc0inplz: but again, I would much prefer you join Eligius than setup a new pool :P
315 2011-07-09 01:41:55 <Wuked1> luke-jr: Sorry to sound like a massive n00b, but I've cloned the latest bitcoin from git, how do I merge your branch here: http://luke.dashjr.org/programs/bitcoin/w/bitcoind/luke-jr.git/shortlog/refs/heads/getwork_dedupe ?
316 2011-07-09 01:42:26 <^1bitc0inplz> luke-jr: thank you, I've already got my own pool.... but this was more a matter of personal curiosity :-)
317 2011-07-09 01:42:36 <luke-jr> Wuked1: while I'm sharing some of my changes, that doesn't mean I offer tech support to competitors âº
318 2011-07-09 01:42:47 <luke-jr> Wuked1: especially for something that's "git 101"

326 2011-07-09 01:56:37 <Wuked1> luke-jr: Can you explain why your change hasn't been adopted by the main branch ? Is it only suitable for clients requesting lots of work ?
327 2011-07-09 01:56:51 <luke-jr> Wuked1: ask them
328 2011-07-09 01:57:07 <BlueMatt> which branch?
329 2011-07-09 01:57:19 <luke-jr> BlueMatt: getwork_dedupe
330 2011-07-09 01:57:32 <BlueMatt> I would say it should be included in 0.4
331 2011-07-09 01:57:51 <BlueMatt> since I (and probably others) only saw that after 0.3.24 was in rc, it didnt make it
332 2011-07-09 01:59:51 <Wuked1> probably another n00b question, but why is the bitcoind i just build from source over23mb in size, and the one already compiled only 3mb in size ?
333 2011-07-09 02:00:14 <BlueMatt> strip it
334 2011-07-09 02:00:30 <gmaxwell> Something fishy is going on. I noticed that my uncapped node that had hundreds of inbound connections the other day was down to ~50. I thought perhaps other nodes had forgotten about it because it didn't have the IRC hopping patch (though it does join 24 channels), so I restarted it. A few minutes after restarting it, it had _1433_ inbound connections!
335 2011-07-09 02:00:46 <luke-jr> Wuked1: sed -i 's/static/dynamic/' makefile.unix
336 2011-07-09 02:01:00 <BlueMatt> gmaxwell: indeed...

338 2011-07-09 02:01:20 <luke-jr> gmaxwell: mine joins all 101 channels
339 2011-07-09 02:01:21 <BlueMatt> luke-jr: lol
340 2011-07-09 02:01:23 <gmaxwell> I wanted to get a pcap of the inbound connection attemps, so I killed it and restarted it, but now it's gaining new connections slower. Only up to 302 now.
341 2011-07-09 02:01:43 <BlueMatt> gmaxwell: you might have ended up in dns there...
342 2011-07-09 02:01:45 <gmaxwell> luke-jr: you can't join all 101 channels, the IRC server just starts ignoring the requests at 25 or so.
343 2011-07-09 02:01:55 <luke-jr> gmaxwell: that's why I open 5 connections

347 2011-07-09 02:02:55 <kunnis> What is IRC used for? Is it only for finding the addresses of other users?

355 2011-07-09 02:03:33 <gmaxwell> luke-jr: in any case, have you also observed enormous numbers of _inbound_ connections?
356 2011-07-09 02:03:39 <kunnis> as a psudo-random idea, why not broadcast the major traffic over IRC?
357 2011-07-09 02:03:41 <gmaxwell> Because that sure as hell sounds like a sybil attack.
358 2011-07-09 02:03:41 <BlueMatt> Wuked1: strip it
359 2011-07-09 02:03:59 <BlueMatt> gmaxwell: was your node in dns?
360 2011-07-09 02:04:10 <BlueMatt> though it still shouldnt be that high
361 2011-07-09 02:04:17 <kunnis> MOst nodes what to find out when a block is created, so why not transmit those over irc?
362 2011-07-09 02:04:40 <gmaxwell> BlueMatt: How the heck should I know, and why would it not happen until I restarted it? (e.g. I was at ~50, restarted, and shot to 1433)
363 2011-07-09 02:05:08 <BlueMatt> gmaxwell: ok, thats odd, might be a sybil on when people join irc then

369 2011-07-09 02:06:44 <BlueMatt> Wuked1: as a side note dont make everything dynamic unless you are only using it on that machine, or the same distro/version

393 2011-07-09 02:18:15 <gmaxwell> up to 579 inbound now... But still not more than one per IP. There are two /24s with 2. One /16 with 4, and a bunch of /16s with 2.. but nothing that looks like obvious trouble.

408 2011-07-09 02:25:30 <BlueMatt> ok this is absolutely disturbing: number of accepting nodes for each version has changed almost none since 0.3.24 was released, except for 0.3.23 and 0.3.24, 0.3.23 has gone from 1423 to 595, as one might expect, but 0.3.24 has gone from 13 to 46...
409 2011-07-09 02:25:32 <BlueMatt> wtf?
410 2011-07-09 02:25:49 <BlueMatt> there has to be something wrong with 0.3.24
411 2011-07-09 02:26:29 <gmaxwell> BlueMatt: can you make a list of nodes that went away so we can check to see if they are listening?

421 2011-07-09 02:30:48 <gmaxwell> ^ or because they aren't disconnecting people, their connection slots are filling up and you can't probe them.
422 2011-07-09 02:31:06 <BlueMatt> doesnt seem right...seems like that is happening *way* too quick for that to be right
423 2011-07-09 02:31:35 <gmaxwell> On my IRC multiconnect client I'm getting _hundreds_ of connections a few minutes after restarting.

427 2011-07-09 02:32:37 <BlueMatt> 10373 <- number of nodes which have gone offline in the past 24h and were on 0.3.23

429 2011-07-09 02:33:15 <BlueMatt> 708 for 0.3.22
430 2011-07-09 02:33:23 <BlueMatt> so clearly there is a lot of natural turnover
431 2011-07-09 02:33:29 <BlueMatt> but that just seems wrong
432 2011-07-09 02:33:44 <BlueMatt> when do full-nodes drop the connection?
433 2011-07-09 02:34:02 <gmaxwell> Can you filter that down to just nodes that had been stable for a while?
434 2011-07-09 02:34:11 <gmaxwell> I think it's after they connect but before the version message.
435 2011-07-09 02:34:12 <BlueMatt> hm...let me see
436 2011-07-09 02:35:01 <gmaxwell> Which is why I wanted you to list them, if we can still bring up tcp connections to them, they're just full.
437 2011-07-09 02:35:12 <gmaxwell> (I think)
438 2011-07-09 02:35:35 <BlueMatt> 144 for 0.3.22 which were fist seen to be up >24h ago

445 2011-07-09 02:38:10 <gmaxwell> jgarzik: how many inbound connections are you seeing now?
446 2011-07-09 02:38:39 <BlueMatt> let me go read the lib Im using, see where it would complain on a droped connection
447 2011-07-09 02:38:46 <jgarzik> 114 connections, 139m
448 2011-07-09 02:38:48 <BlueMatt> will it drop before you send version, or after
449 2011-07-09 02:38:50 <jgarzik> memory keeps climbing
450 2011-07-09 02:39:18 <gmaxwell> jgarzik: yea, there is some per-connection memory usage. Once you're capped out on connections it should be stable.
451 2011-07-09 02:40:46 <BlueMatt> whats the flag, -maxconnections?

454 2011-07-09 02:42:13 <BlueMatt> well I just want to set it to 1 for now to test where the dropoff happens

588 2011-07-09 04:12:35 <jgarzik> gmaxwell: "delete old addresses" seems simple, but I would hate to lose useful addresses by being overly aggressive
589 2011-07-09 04:13:31 <Diablo-D3> does it take room to store them?
590 2011-07-09 04:13:32 <jgarzik> but in general, like with the block index, we store addresses in bdb, so (a) storing them in RAM is triple-caching and wasteful, and (b) they need pruning to avoid griefers adding 'the whole internet' to our address book
591 2011-07-09 04:13:45 <jgarzik> Diablo-D3: it loads the entire database into RAM
592 2011-07-09 04:13:50 <Diablo-D3> meh
593 2011-07-09 04:13:54 <Diablo-D3> trim after 1 million
594 2011-07-09 04:14:23 <gmaxwell> Trying to connect to old long dead ones also wastes time.
595 2011-07-09 04:14:24 <Diablo-D3> sort by last tx used date
596 2011-07-09 04:14:29 <Diablo-D3> er
597 2011-07-09 04:14:32 <Diablo-D3> last connection used date
598 2011-07-09 04:14:41 * Diablo-D3 hates how tx is an overloaded term
599 2011-07-09 04:17:39 <gmaxwell> Perhaps keep track of how many contiguous connect failures it's had (also resetting to zero on inbound, and not counting failures when there are no nodes up). Nodes with >0 don't get passed on to neighbors, nodes with >2 are pruned oldest first. Or something like that.

607 2011-07-09 04:21:33 <gmaxwell> Perhaps before IRC gets turned off by default the dnsseed stuff should be augmented with a reporting mechanism where you tell each authority about your existance after your first successful inbound connection.
608 2011-07-09 04:22:14 <gmaxwell> This way future pruning doesn't risk making nodes get forgotten, since the dnsseed authorities could reasonably have longer memories.

612 2011-07-09 04:33:56 <upb> hmm wouldnt that allow flooding the zone with loads of fake addresses?
613 2011-07-09 04:34:19 <gmaxwell> upb: No, because the dnsseeds should be testing them itself.
614 2011-07-09 04:34:27 <upb> if you mitigate that by loading them into some 'to be checked' queue, it would allow for ddos
615 2011-07-09 04:34:34 <gmaxwell> (Matt's does, dunno about other ones)
616 2011-07-09 04:35:23 <gmaxwell> upb: it would only allow flooding the to be checked queue, and who cares? An authority could reasonable check the whole internets worth of addresses in a few days.

623 2011-07-09 04:43:22 <upb> no
624 2011-07-09 04:43:29 <gmaxwell> Yes it does.
625 2011-07-09 04:43:47 <upb> that way you cant add someone elses address in there
626 2011-07-09 04:43:57 <gmaxwell> It's the same either way:
627 2011-07-09 04:44:53 <gmaxwell> I send a spoofed UDP packet (which doesn't generally work because most end user providers do urpf, but we'll ignore that): then later some poor sucker gets one failed connection attempt from me.
628 2011-07-09 04:44:57 <gmaxwell> vs
629 2011-07-09 04:45:29 <gmaxwell> I send a spoofe tcp sync: then right away some poor sucker gets a syn-ack from mars.
630 2011-07-09 04:45:38 <gmaxwell> s/spoofe/spoofed/
631 2011-07-09 04:45:46 <upb> hmmmm
632 2011-07-09 04:46:10 <upb> yes
633 2011-07-09 04:46:32 <gmaxwell> Either way: one spoofed packet in, one unwelcome packet to other people. Also, since we control the test attempts, we can do N spoofed packets in in a short timespan, 1 unwelcome packet out.
634 2011-07-09 04:47:11 <gmaxwell> Otherwise someone who keeps sending us spoofed syns is going to bounce syn-acks to some target.
635 2011-07-09 04:49:00 <upb> yeah i guess youre right since the checker only does one connection there isnt any amplification

750 2011-07-09 07:47:50 <semarjt> I think there is not
751 2011-07-09 07:47:51 <wumpus> only way I can think of is to move all addresses to another label
752 2011-07-09 07:48:22 <wumpus> not sure how to do that through the JSON interface though
753 2011-07-09 07:48:30 <semarjt> don't think you can
754 2011-07-09 07:48:46 <wumpus> deleteaccount would be a sensible command
755 2011-07-09 07:48:49 <wumpus> imo
756 2011-07-09 07:49:05 <wumpus> as spec it would move all addresses of that account to the "" main account
757 2011-07-09 07:49:10 <semarjt> seems obvious to me, but then i do CRUD all day
758 2011-07-09 07:49:37 <wumpus> I'd say open a github issue :)

829 2011-07-09 08:09:40 <phantomcircuit> of course i can
830 2011-07-09 08:09:46 <phantomcircuit> what's he going to do?

832 2011-07-09 08:10:31 <phantomcircuit> he's in san francisco
833 2011-07-09 08:10:48 <phantomcircuit> i could probably call someone at comcast and get him disconnected
834 2011-07-09 08:10:52 <gmaxwell> phantomcircuit: I'm curious about the high rate of dropped transaction I'm seeing. It doesn't matter to me personally, but if the txn aren't junk (and this doesn't look like junk) then it may be adversly impacting network health.
835 2011-07-09 08:11:16 <phantomcircuit> gmaxwell, the problem is that old clients reject new clients txs
836 2011-07-09 08:11:28 <phantomcircuit> this is an issue i have pointed out before
837 2011-07-09 08:11:32 <phantomcircuit> but was basically ignored
838 2011-07-09 08:11:35 <gmaxwell> ::sigh::
839 2011-07-09 08:12:03 <gmaxwell> I've pointed that out to, but that is _NOT_ the issue I'm talking about: I'm sitting here with a .24 node seeing it reject about 800 TXN per hour.
840 2011-07-09 08:12:04 <lfm> on what grounds? suspician of being spam?
841 2011-07-09 08:12:39 <gmaxwell> lfm: yea, the .23 fee rules are rejected by the <=.21 nodes, and there are still a lot of <=.21 nodes out there.
842 2011-07-09 08:12:52 <gmaxwell> But thats not the issue I'm seeing, though its an issue too.
843 2011-07-09 08:14:03 <lfm> the .24 node is rejecting a lot too you say?
844 2011-07-09 08:15:01 <gmaxwell> Yes. About 800/hr, and now that I've changed it to log the txid, I'm lookg at them and the ones I've checked so far don't look that spammy.

876 2011-07-09 08:55:40 <gmaxwell> Right. Well, if they are also connecting to lots of other nodes they may be wasting a lot of connection slots, but there isn't much we can do about that.

915 2011-07-09 09:43:13 <kayK> What is MultiCoin?
916 2011-07-09 09:43:44 <sacarlson> MultiCoin is a branched bitcoin client http://forum.bitcoin.org/index.php?topic=24209.msg300830#msg300830
917 2011-07-09 09:44:30 <sacarlson> that can operate and create an infinite number of block chain crypto currencies

920 2011-07-09 09:46:00 <sacarlson> I'm not sure about NameCoin as that's has features I havn't looked at yet but in the future I'm more looking for alternate chains
921 2011-07-09 09:47:10 <kayK> Well your MultiCoin concept is a good one. Good luck with it.

979 2011-07-09 11:12:42 <simplechat> ok, so when you take the blockhead and do the doublehash, it has to come under that for it to count as a validly mined block?
980 2011-07-09 11:12:53 <BlueMatt> yep
981 2011-07-09 11:13:06 <simplechat> :) thanks
982 2011-07-09 11:15:37 <simplechat> also, what's the current best for the GPU miners
983 2011-07-09 11:15:43 <simplechat> are they on the order of mhashes, ghashes, thashes?
984 2011-07-09 11:16:02 <Joric> i've seen 48 gh rig on youtube

1034 2011-07-09 11:56:46 <molecular> sipa, I'm trying to force discussion of sipa:showwallet: http://forum.bitcoin.org/index.php?topic=8091.msg344165#msg344165 (and above)
1035 2011-07-09 11:57:54 <molecular> sipa, I want the importprivkey in default branch quite badly ;), but there are valid objections against dumpprivkey (usage problems due to key being in more than one wallet)
1036 2011-07-09 11:58:08 <molecular> sipa, is it possible to separate the two?
1037 2011-07-09 11:59:29 <sipa> molecular: i was just answering in the thread
1038 2011-07-09 11:59:58 <molecular> cool ;)
1039 2011-07-09 12:00:46 <Joric> speaking of importkey - https://github.com/samr7/vanitygen is quite cool thing :)
1040 2011-07-09 12:00:53 <molecular> yeah, I'm using that
1041 2011-07-09 12:00:56 <molecular> it's awesome
1042 2011-07-09 12:01:52 <molecular> still working on "molecular", quite long
1043 2011-07-09 12:02:13 <Joric> it says there's also a vanity address patch for official client
1044 2011-07-09 12:02:24 <molecular> yeah, I saw that somewhere
1045 2011-07-09 12:02:41 <sipa> vanitygen is like 100x faster than the vanity patch
1046 2011-07-09 12:03:10 <molecular> I think it's cool to have that in external tool. why clutter the client with that?
1047 2011-07-09 12:03:21 <molecular> given there's "importprivkey" of course
1048 2011-07-09 12:03:45 <molecular> btw sipa: I tested importprivkey and dumpprivkey successfully with no problems
1049 2011-07-09 12:04:10 <molecular> a couple times actually since you rebased ~2 weeks ago
1050 2011-07-09 12:04:16 <sipa> good
1051 2011-07-09 12:04:28 <sipa> no problems with incorrectly reported balances directly after importing?

1055 2011-07-09 12:06:23 <molecular> I can only confirm that this worked in one instance. The other times I didn't directly check the balance
1056 2011-07-09 12:06:34 <molecular> should I retest this?

1061 2011-07-09 12:07:42 <sipa> i did some changes after that, which could have fixed it

1089 2011-07-09 12:27:48 <molecular> git remote add sipa git://github.com/sipa/bitcoin.git

1092 2011-07-09 12:28:09 <molecular> this conflicts (src/wallet.cpp)
1093 2011-07-09 12:28:17 <molecular> it this correct to do it that way?
1094 2011-07-09 12:28:51 <molecular> sorry, last line should read "git merge sipa/showwallet"
1095 2011-07-09 12:29:47 <sipa> depends on whether you just want my showwallet branch, or a merge of current git head with it
1096 2011-07-09 12:29:58 <BlueMatt> sipa: my plan: do nothing, let old clients get mad, give errors, show no balance etc, and just handle the "you have an unencrypted key in your encrypted wallet" result gracefully
1097 2011-07-09 12:30:08 <BlueMatt> which would mean importing the key but not putting it in pool or ADDRESS

1102 2011-07-09 12:30:49 <molecular> sipa, I just want to re-test showwallet
1103 2011-07-09 12:31:08 <sipa> then just do git checkout showwallet
1104 2011-07-09 12:31:11 <molecular> should I just "pull" showwallet or "clone" or what
1105 2011-07-09 12:31:17 <sipa> and maybe git reset --hard sipa/showwallet
1106 2011-07-09 12:31:46 <Blitzboom> any other main features besides wallet encryption 0.4 will bring?

1108 2011-07-09 12:32:01 <Blitzboom> great
1109 2011-07-09 12:32:12 <BlueMatt> probably nothing huge besides that
1110 2011-07-09 12:32:32 <Blitzboom> how about introducing mBTC?
1111 2011-07-09 12:32:45 <sipa> i'd wait with that

1118 2011-07-09 12:33:49 <molecular> that just says: currently on no branch, nothing to commit
1119 2011-07-09 12:34:01 <sipa> then do git checkout showwallet
1120 2011-07-09 12:34:04 <sipa> what happens?
1121 2011-07-09 12:34:16 <Eliel_> Is there a reason to wait with the mBTC thing? just make it a configuration option. Then people can decide themselves how they'd prefer to see the balance.
1122 2011-07-09 12:34:18 <molecular> nick@zero ~/bitcoin/bitcoin_5 $ git checkout sipa/showwallet

1137 2011-07-09 12:36:37 <BlueMatt> arg...
1138 2011-07-09 12:36:50 <kinlo> nobody is mining on the testnet ? :)
1139 2011-07-09 12:36:54 <sipa> and also 30MiB of possibly lost allocated memory
1140 2011-07-09 12:37:21 <BlueMatt> well that might explain the OOMs
1141 2011-07-09 12:37:42 <Joric> kinlo, i'm mining on the testnet-in-a-box with difficulty 0.125, it feels so good
1142 2011-07-09 12:37:44 <Blitzboom> anyway, usage of smaller denominations would be psychologically beneficial imo
1143 2011-07-09 12:37:52 <Blitzboom> you own "more"
1144 2011-07-09 12:37:57 <kinlo> mmmz, yeah, talking about real testnet :p
1145 2011-07-09 12:38:07 <sipa> running an -O0 compiled bitcoin in valgrind is horribly slow, though
1146 2011-07-09 12:38:08 <BlueMatt> Blitzboom: well write a patch ;)
1147 2011-07-09 12:38:10 <molecular> sipa: before testing the "balance update bug", should I sync the blockchain to the point where the tx to the address I want to import is included?
1148 2011-07-09 12:38:26 <BlueMatt> sipa: running with -O2 in valgrind is slow too
1149 2011-07-09 12:38:48 <sipa> molecular: i believe dinox had a full block chain when he encountered the bug, but i'm not sure
1150 2011-07-09 12:39:08 <molecular> ok, I will simply test both cases
1151 2011-07-09 12:40:29 <Joric> could anyone explain why testnet-in-a-box uses m and n prefixes simultaneously?
1152 2011-07-09 12:40:50 <BlueMatt> sipa: what is your take on wallet encryption backward compat? I think the only options Ive seen are either rename wallet.dat, or do nothing and let old clients generate errors
1153 2011-07-09 12:41:14 <Joric> vanitygen says prefix m/n no possible :(
1154 2011-07-09 12:41:39 <Blitzboom> dat.wallet :D
1155 2011-07-09 12:41:51 <BlueMatt> more like wallet-crypted.dat
1156 2011-07-09 12:41:57 <sipa> BlueMatt: renaming the file is a though thing to do, but from a usability standpoint possibly necessary
1157 2011-07-09 12:42:38 <BlueMatt> I agree its though, but I actually think its better for the client to generate crazy error messages than just open up with a clean wallet, leaving the user to think his wallet got deleted
1158 2011-07-09 12:42:53 <sipa> that's a good point

1187 2011-07-09 13:01:39 <BlueMatt> its not a-z, A-Z
1188 2011-07-09 13:02:22 <BlueMatt> and if you mean mainnet, it has to start with 1
1189 2011-07-09 13:02:30 <Joric> hehe cool i just imported a test address
1190 2011-07-09 13:03:05 <molecular> was money on that address?
1191 2011-07-09 13:03:05 <Joric> gotta generate something fancy

1196 2011-07-09 13:03:45 <molecular> zero doesn't count, not for testing balance update bug ;)
1197 2011-07-09 13:04:08 <Joric> omg theres a bug?
1198 2011-07-09 13:04:24 <molecular> not a bad one
1199 2011-07-09 13:04:27 <molecular> if at all
1200 2011-07-09 13:04:37 <sipa> maybe not anymore :)
1201 2011-07-09 13:04:45 <molecular> still compiling
1202 2011-07-09 13:05:07 <molecular> then I can retest ;)
1203 2011-07-09 13:05:26 <Joric> i'm wondering if i generate vanity address could anyone generate exactly the same address using vanity gen? :) didn't check if it uses a random seed
1204 2011-07-09 13:06:21 <molecular> highly unlikely
1205 2011-07-09 13:06:25 <Joric> nope looks they are different each time
1206 2011-07-09 13:06:27 <molecular> it uses random seed
1207 2011-07-09 13:06:39 <molecular> Joric, "looks like", hehe. might still be possible.
1208 2011-07-09 13:06:51 <molecular> there's still enough bits left to make it insanely unlikely.
1209 2011-07-09 13:07:16 <molecular> try finding the key to some address you know has a lot of money on it by entering it completely into vanitygen ;)

1302 2011-07-09 13:44:59 <diki> so basically, if i compile a fully linux dependant program ON linux for windows, will it work?
1303 2011-07-09 13:45:12 <diki> will it work on windows
1304 2011-07-09 13:45:15 <BlueMatt> depends on how you compile it
1305 2011-07-09 13:45:23 <BlueMatt> windows and linux binaries have a different format
1306 2011-07-09 13:45:29 <BlueMatt> and obviously depend on different libs
1307 2011-07-09 13:45:30 <diki> eah
1308 2011-07-09 13:45:32 <diki> winpe
1309 2011-07-09 13:45:44 <BlueMatt> if you compile with mingw, yes but then it wont run on linux (without wine)
1310 2011-07-09 13:46:08 <diki> erm....if i compile with mingw on linux, that means that the same program will work on linux
1311 2011-07-09 13:46:17 <BlueMatt> no it wont
1312 2011-07-09 13:46:19 <diki> because it would have a compiled binary for linux
1313 2011-07-09 13:46:21 <BlueMatt> mingw compiles for windows
1314 2011-07-09 13:46:23 <diki> which it does
1315 2011-07-09 13:46:33 <BlueMatt> read up on what cross compiling is/means
1316 2011-07-09 13:46:39 <diki> yes i know dude
1317 2011-07-09 13:46:45 <jtaylor> then maybe someone can comment on http://forum.bitcoin.org/index.php?topic=27308.0 that its already used for the binaries, so probably no regressions
1318 2011-07-09 13:46:49 <diki> but i am too lazy to type every bit of word

1383 2011-07-09 14:17:40 <doublec> kveras, the description for the app says the wallet file is backed up in the cloud. Have you tried restoring?
1384 2011-07-09 14:17:43 <Joric> takes like 1 second to generate
1385 2011-07-09 14:18:35 <kveras> doublec, I can't decipher where I should find it. also, looking through the code for the app, I am afraid that my new wallet overwrote the first one in the cloud.

1397 2011-07-09 14:22:35 <kveras> doublec, it indicates that it has catched up with the chain.
1398 2011-07-09 14:22:42 <kveras> and I have got a new adress

1406 2011-07-09 14:25:26 <kveras> the app downloads a snapshot of the chain when installing, then it just catches up with the ones since installation

1424 2011-07-09 14:38:43 <senseles> you can place it at the end before the last line }

1470 2011-07-09 14:57:19 <molecular> is it because they contain many tx?
1471 2011-07-09 14:57:35 <redshark1802> it's really frustrating
1472 2011-07-09 14:57:35 <BlueMatt> its because you are connected to pre-0.3.24 nodes
1473 2011-07-09 14:57:51 <BlueMatt> if you use dnsseed and connect to 0.3.24 nodes, it should be fine

1480 2011-07-09 14:58:34 <BlueMatt> of the problem
1481 2011-07-09 14:59:06 <doublec> molecular: I have a 0.3.24 node here if you are looking for one to connect too: 206.71.179.116
1482 2011-07-09 14:59:06 <sipa> there are two issues: 1) OOM 2) use of uninitilialized value
1483 2011-07-09 14:59:13 <sipa> about the OOM, i have no idea
1484 2011-07-09 14:59:16 <BlueMatt> oh
1485 2011-07-09 14:59:17 <molecular> since I'm connecting to only one node and that is mine, the fix is easy ;)
1486 2011-07-09 14:59:32 <BlueMatt> and the uninitialized value is causing problems?
1487 2011-07-09 14:59:45 <sipa> not at all, it seems
1488 2011-07-09 14:59:50 <sipa> but it worried me
1489 2011-07-09 14:59:56 <BlueMatt> oh, ok
1490 2011-07-09 15:00:06 <sipa> also, 0.3.23 does not seem to leak less memory than 0.3.24
1491 2011-07-09 15:00:18 <sipa> but i'd need to run it for a long time to be sure

1524 2011-07-09 15:22:37 <sipa> why?
1525 2011-07-09 15:22:49 <sipa> if the pagesize is 4096
1526 2011-07-09 15:22:59 <sipa> you need to mask out all bits present in 4095
1527 2011-07-09 15:23:05 <sipa> so that it becomes a multiple of 4096
1528 2011-07-09 15:23:07 <BlueMatt> 1000... you want to drop 1111... not 0111...?

1570 2011-07-09 15:52:41 <sipa> exactly
1571 2011-07-09 15:52:47 <BlueMatt> depends on how big b is, but yea you want to lock two pages then
1572 2011-07-09 15:53:05 <sipa> a should be rounded down to a page boundary, a+b should be rounded up to a page boundary

1601 2011-07-09 16:20:55 <unclemantis> yes sir! LOL
1602 2011-07-09 16:21:04 <unclemantis> ok...... let me ask again in a different way
1603 2011-07-09 16:21:11 <BlueMatt> well then you know why instawallet cant get hacked via a rainbow table
1604 2011-07-09 16:21:19 <unclemantis> how does instawallet.org prevent wardialing type attacks?
1605 2011-07-09 16:21:58 <BlueMatt> Id be willing to bet ip bans on quick-requesting ips, but also look at how many bits you have to brute force
1606 2011-07-09 16:22:14 <BlueMatt> its slightly...way too huge to bruteforce
1607 2011-07-09 16:22:51 <phantomcircuit> personally id rather just allow brute force attacks but i guess ill have to defend against them
1608 2011-07-09 16:22:52 <phantomcircuit> *sigh*
1609 2011-07-09 16:22:56 <unclemantis> well i am not going to try, that is just wrong

1613 2011-07-09 16:23:21 <unclemantis> i will assume it is safe and just stick with my windows wallet
1614 2011-07-09 16:23:31 <phantomcircuit> BlueMatt, uses a long lived cookie right
1615 2011-07-09 16:23:40 <BlueMatt> phantomcircuit: its just a string like uV1ArDmWw-qdx4jsY88L9g which is in the url and the cookie
1616 2011-07-09 16:24:27 <BlueMatt> so allowing bruteforcing isnt an option there as you arent screwing stupid users, you are screwing them all
1617 2011-07-09 16:24:39 <BlueMatt> but in this case, allowing brute forcing wont get attackers anywhere
1618 2011-07-09 16:25:24 <phantomcircuit> i bet i could ddos them with generating addresses
1619 2011-07-09 16:25:40 <BlueMatt> quite possibly
1620 2011-07-09 16:26:01 <BlueMatt> but thats a very different case than brute-forcing
1621 2011-07-09 16:26:12 <gim> I know there are other priorities, but I'd like to know what you guys think about this kind of stuff https://github.com/sgimenez/bitcoin/commit/f43f0d6bffd8bad4af382b1e84ed5e51f0bcb673
1622 2011-07-09 16:26:15 <BlueMatt> brute-forcing gets you coins, ddos is just for the lulz, which is just fucking pointless

1630 2011-07-09 16:27:44 <BlueMatt> thats not as hard as ecdsa key gen
1631 2011-07-09 16:28:21 <forrestv> ecdsa key gen is actually pretty easy, or so i thought..

1646 2011-07-09 16:30:37 <phantomcircuit> yeah
1647 2011-07-09 16:30:39 <BlueMatt> when the session is opening, it does take a bit, but still not that much

1679 2011-07-09 16:37:03 <phantomcircuit> and if you have custom hw you can massively reduce the cost

1684 2011-07-09 16:37:24 <BlueMatt> it was actually 10% increase per connection
1685 2011-07-09 16:37:32 <BlueMatt> so total 10% if everyone used it
1686 2011-07-09 16:38:04 <gmaxwell> and the rsa sign is a 99.9% of the work for the server side of SSL, there is some additional back and forth workâ¦
1687 2011-07-09 16:38:05 <phantomcircuit> gmaxwell, the individual ops are fast
1688 2011-07-09 16:38:13 <phantomcircuit> everything combined is expensive
1689 2011-07-09 16:38:24 <BlueMatt> then you are doing something wrong

1703 2011-07-09 16:45:31 <BlueMatt> jandd: yes, but if phantomcircuit's claims are correct, then they would have had to, at a minimum, roll out new hardware
1704 2011-07-09 16:46:07 <phantomcircuit> BlueMatt, this system does 10k concurrent http connections
1705 2011-07-09 16:46:15 <phantomcircuit> or 300 https connections
1706 2011-07-09 16:46:22 <BlueMatt> then you are doing something wrong
1707 2011-07-09 16:46:33 <BlueMatt> benchmarking, or bad server config, or, or, or
1708 2011-07-09 16:46:40 <phantomcircuit> no im not
1709 2011-07-09 16:46:46 <BlueMatt> google disagrees
1710 2011-07-09 16:46:54 <phantomcircuit> as jandd said it's the original ssl handshake that's expensive
1711 2011-07-09 16:47:04 <BlueMatt> yes, and IIRC gmail users have to do that too
1712 2011-07-09 16:47:06 <phantomcircuit> for normal https it's fine
1713 2011-07-09 16:47:18 <BlueMatt> gmail users dont get to skip that part
1714 2011-07-09 16:47:26 <phantomcircuit> they use keep alive
1715 2011-07-09 16:47:31 <BlueMatt> so?
1716 2011-07-09 16:47:32 <phantomcircuit> so they setup the connection once
1717 2011-07-09 16:47:34 <BlueMatt> so will any users
1718 2011-07-09 16:47:38 <BlueMatt> on any site
1719 2011-07-09 16:48:01 <phantomcircuit> yes
1720 2011-07-09 16:48:06 <phantomcircuit> but that wont stop an attacker
1721 2011-07-09 16:48:14 <phantomcircuit> from making you generate a buttload of sessions
1722 2011-07-09 16:48:24 <BlueMatt> if you think google cant handle a ddos from users doing that, Id say wtf is wrong with you
1723 2011-07-09 16:48:30 <BlueMatt> and if they didnt roll out new hardware...
1724 2011-07-09 16:48:31 <phantomcircuit> uh i wasn't talking google
1725 2011-07-09 16:48:38 <phantomcircuit> i was talking smaller sites
1726 2011-07-09 16:48:59 <BlueMatt> Im saying if a site the size of google doesnt have to roll out new hardware to keep people from doing that, neither do small sites
1727 2011-07-09 16:49:06 <anu> hi
1728 2011-07-09 16:49:09 <anu> i'd like to contribute some - looks to me there are a lot of usability issues that need fixing
1729 2011-07-09 16:49:14 <gmaxwell> So, I get 100 connections per second using ab like above against some small ssl site I run. But if I run 32 of them in parallel, I get an average of about 9.7 connections per second each. So clearly something is borken with ab's concurrency.
1730 2011-07-09 16:49:18 <gmaxwell> And this site is using SSL/TLS Protocol: TLSv1/SSLv3,DHE-RSA-AES256-SHA,4096,256
1731 2011-07-09 16:49:19 <anu> like backup / restore from the UI
1732 2011-07-09 16:49:35 <anu> too bad I don't get it to build :(
1733 2011-07-09 16:49:39 <gmaxwell> Which is a zillion times more expensiv than you ned it to be.
1734 2011-07-09 16:49:46 <phantomcircuit> BlueMatt, attacking google via https exhaustion would require a massive botnet and get you fuck all
1735 2011-07-09 16:49:48 <BlueMatt> anu: if you write autotools, it will all come
1736 2011-07-09 16:49:59 <BlueMatt> phantomcircuit: but they have to have the servers to prevent that
1737 2011-07-09 16:50:06 <phantomcircuit> yes and they do
1738 2011-07-09 16:50:16 <BlueMatt> but not extra ones beyond http
1739 2011-07-09 16:50:17 <anu> I guess I have wrong versions of files.
1740 2011-07-09 16:50:26 <phantomcircuit> any one attacker could only cause a relatively small increase in cpu cycles across their entire system
1741 2011-07-09 16:50:36 <BlueMatt> phantomcircuit: lol, ok
1742 2011-07-09 16:50:49 <phantomcircuit> it would be a waste of your time

1751 2011-07-09 16:52:22 <anu> i guess I could sort that out

1753 2011-07-09 16:52:33 <gmaxwell> ldd won't help you much, bitcoin builds a static binary by default for some awful reason.

1805 2011-07-09 17:06:07 <prof7bit> it could be foreseen what range is needed for an integer and used a fixed length.
1806 2011-07-09 17:06:26 <prof7bit> my humble opinion.
1807 2011-07-09 17:07:20 <forrestv> something like 1 million
1808 2011-07-09 17:07:32 <forrestv> so 15MB :P
1809 2011-07-09 17:08:06 <prof7bit> its using 5 bytes to store 4 bytes, i guarantee this thing is wasting more space than it saves on average

1820 2011-07-09 17:11:04 <forrestv> so if you parse some data and later reencode it, it might have a different binary repr
1821 2011-07-09 17:11:13 <forrestv> the bitcoin client uses the shortest representation but accepts all
1822 2011-07-09 17:11:27 <forrestv> that wouldn't matter, except for the fact that the binary data is hashed

1831 2011-07-09 17:12:11 <luke-jr_> o
1832 2011-07-09 17:12:21 <gmaxwell> luke-jr_: txin len, txout length, #txn in a block, and extranonce.
1833 2011-07-09 17:12:35 <forrestv> gmaxwell, #txn in a block isn't hashed, though
1834 2011-07-09 17:12:35 <gmaxwell> luke-jr_: you didn't wonder why it normally wrapped extranonce at 0xfd?
1835 2011-07-09 17:12:43 <forrestv> and extranonce desn't matter
1836 2011-07-09 17:12:55 <forrestv> no point in decoding coinbase (usually)
1837 2011-07-09 17:13:32 <gmaxwell> forrestv: it doesn't matter for your complaint, no. It matters.. e.g. that luke's patch makes coinbase txn bigger.
1838 2011-07-09 17:14:10 <luke-jr_> gmaxwell: trivially bigger
1839 2011-07-09 17:15:33 <gmaxwell> luke-jr_: sure. It's still a reason to make a little more effort to reset it, e.g. when the transactions change.
1840 2011-07-09 17:16:28 <luke-jr_> gmaxwell: perhaps
1841 2011-07-09 17:21:00 <forrestv> also, bits has redundancy which bugs me for the same reason

1846 2011-07-09 17:24:44 <forrestv> ...

1852 2011-07-09 17:26:45 <forrestv> well, utf-8 isn't used in bitcoin, and ecdsa keys aren't compressed data, whereas bits is a compressed integer
1853 2011-07-09 17:26:58 <forrestv> it's useful to uncompress it and handle that data
1854 2011-07-09 17:27:01 <luke-jr_> â¦
1855 2011-07-09 17:27:08 <gmaxwell> luke-jr_: Bitcoin never actually needs to send a ECDSA public key. You can recover them from a signature plus the address for the key.
1856 2011-07-09 17:27:22 <luke-jr_> gmaxwell: irrelevant, it still DOES
1857 2011-07-09 17:28:03 <luke-jr_> just saying, having multiple encodings is *not* a problem :p
1858 2011-07-09 17:28:22 <gmaxwell> luke-jr_: right, I was agreeing with you. There are lots of technically wasteful bits... considering the computation and code complexity, its not even a bad idea.
1859 2011-07-09 17:28:39 <forrestv> not usually, but in bitcoin, the hash of the encoded data matters (quite a bit) :p meh, just been a minor annoyance for me
1860 2011-07-09 17:30:15 <gmaxwell> Yea, it means you can't expect to decode and then rebuild something and get the same thing back. "So don't do that"
1861 2011-07-09 17:32:03 <forrestv> hm, actually, does bitcoin even do it that way?
1862 2011-07-09 17:32:18 <gmaxwell> In any case, there is usually no design design you can make which won't cause people to complain that it wasn't another.
1863 2011-07-09 17:32:43 <forrestv> it decodes it into a c++ object ... is hashing done directly on the object?
1864 2011-07-09 17:33:56 <gmaxwell> At least in some cases it is.
1865 2011-07-09 17:34:51 cryptocnt has joined
1866 2011-07-09 17:35:17 <forrestv> huh ... so the hash internally in bitcoin is computed as doublesha(encode(decode(data)))
1867 2011-07-09 17:35:22 <forrestv> not the format on the wire

1869 2011-07-09 17:35:37 <forrestv> so i guess none of what i said matters
1870 2011-07-09 17:37:00 <jgarzik> from bitcoin's perspective, it is not "encoded" the block header is a C++ binary data structure directly referenced in memory

1879 2011-07-09 17:38:29 <knotwork> I think I was told to use version 1.5 ?
1880 2011-07-09 17:40:47 <knotwork> yes the doc build.unix specified version 1.5
1881 2011-07-09 17:41:19 <BlueMatt> knotwork: you arent using 1.5, you are using 1.5.XXXXXXX
1882 2011-07-09 17:41:21 <BlueMatt> aka nightly
1883 2011-07-09 17:41:29 <BlueMatt> or are you on windows?

1906 2011-07-09 17:48:47 <knotwork> maybe odd numbers like 1.5 mean development so anything inside the 1.5 range is all break when they feel lke it
1907 2011-07-09 17:48:55 <knotwork> until 1.6 production version
1908 2011-07-09 17:49:17 <BlueMatt> no, they just dont follow versioning in nightlies
1909 2011-07-09 17:49:25 <luke-jr_> BlueMatt: is there a reason Bitcoin doesn't support the newer version anyway?
1910 2011-07-09 17:49:51 <BlueMatt> because we use stable versions here?
1911 2011-07-09 17:49:54 <luke-jr_> I would think at least some #ifdef could detect it

2013 2011-07-09 20:10:24 <prof7bit> when reading a VarStr (which has a VarInt as length) from the network (for example in the version message) does the standard client check the bounds of the buffer and the size of the string or can I crash it? I am too lazy to look for myself now. I just had this idea while implementing the parsing of the protocol messages.

2041 2011-07-09 20:44:57 <gmaxwell> Because simply trusting peers about the block count will result in idiots claiming that there are 99999999999 blocks.

2043 2011-07-09 20:46:51 <b4epoche> stupid enough for you: BOOST_FOREACH(CNode* pnode, vNodes) {total_starting_height += pnode->nStartingHeight;num_nodes++;} ave_starting_height = ((double)total_starting_height/(double)num_nodes);
2044 2011-07-09 20:46:54 <b4epoche> ;-)
2045 2011-07-09 20:47:10 <knotwork> okay I used miniupnpc 1.5 and it compiled but doesnt seem to actually open the port
2046 2011-07-09 20:47:26 <knotwork> I checked with landlord we examoined router it has full gateway upnp enabled
2047 2011-07-09 20:48:36 <knotwork> does the upnp actually work yet or is it just in there being worked on but not necesarily good with all routers or something?
2048 2011-07-09 20:49:05 <prof7bit> <gmaxwell> Because simply trusting peers about the block count will result in idiots claiming that there are 99999999999 blocks. <- simply ask each client for the data of its last block.
2049 2011-07-09 20:49:22 <prof7bit> it must be downloaded anyways
2050 2011-07-09 20:49:32 <gmaxwell> prof7bit: doesn't help.
2051 2011-07-09 20:49:41 RBecker has quit (Laptop!~Ryan@unaffiliated/rbecker|Ping timeout: 240 seconds)
2052 2011-07-09 20:50:35 <gmaxwell> prof7bit: the height isn't in the header... so someone could just pick a random block and say 'this one is 99999999999'
2053 2011-07-09 20:50:58 <prof7bit> you are right, doesnt work :-(
2054 2011-07-09 20:51:42 <b4epoche> my idea for something more robust is to take the average from the first pass and then do another average throwing out outliers
2055 2011-07-09 20:51:57 <prof7bit> maybe make the progress bar an estimation based on the time stamps
2056 2011-07-09 20:52:12 <gmaxwell> The best I could come up with is: Calculate a plausable minimum and maximum from the current time and the chain known so far, exclude results outside of the plausable range. Take the median. Don't display a result if you have less than two contributors, or if you're within N blocks of your the claimed top.
2057 2011-07-09 20:52:41 <gmaxwell> but, meh. thats a lot of complexity for a position estimate!
2058 2011-07-09 20:53:03 <b4epoche> I'll spend time on it if it turns out to be a problem.
2059 2011-07-09 20:53:52 <gmaxwell> I'll claim 99999999999 if people start publishing code that takes the maximum. So there. Now you know it will be a problem. :)
2060 2011-07-09 20:54:01 <b4epoche> roughly how many nodes should one be connected to?
2061 2011-07-09 20:55:36 <gmaxwell> b4epoche: from a security perspective it's only a problem if a badguy controls all your peers. P_picking_a_badguy^peers = P_all_bad. So it depends on how many nodes you think badguys control.
2062 2011-07-09 20:55:42 <prof7bit> gmaxwell: this does not need to be very complicated. use the current time as 100%, block#0 as 0% and the timestamp of the block of the current height as the current position. Make it not move backwards. Should serve the purpose quite well.
2063 2011-07-09 20:56:36 <gmaxwell> prof7bit: dur. Thats great, yea, don't even use the height claims. And the timestamps can't be faked.

2138 2011-07-09 21:43:23 <gmaxwell> cuddlefish: no, it's still a ~2^240 attack, and that only against reduced sha256. Maybe something from that might be useful to someone, but it's not directly applicable.
2139 2011-07-09 21:43:31 <bk128> gmaxwell: yeah that sounds better

2154 2011-07-09 21:58:10 <kgo> Actually I was overthinking things some.
2155 2011-07-09 21:58:28 <kgo> Let me run this by people if they don't mind.
2156 2011-07-09 21:58:40 <kgo> I'm writing an escrow server that works pretty much like clearcoin.
2157 2011-07-09 21:58:56 <kgo> When I was first testing, I was getting a tx fee on every deal because the coins were new.
2158 2011-07-09 21:59:25 <kgo> So I thought I should move them into a 'reserve' account, and send from there, so people doing a quick deal could use other coins that were older.
2159 2011-07-09 21:59:33 <kgo> So it sounds like I don't need to do this at all.
2160 2011-07-09 21:59:47 <kgo> As long as I have some older coins floating around in the wallet?

2205 2011-07-09 22:56:07 <jav__> hey guys! I have been working on a new project and wanted to give you a sneak preview to get your feedback: http://www.transactionradar.com/dashboard .. Essentially I'm trying to build a tool to detect some kinds of double spending right away. This tool connects to 100 nodes and records for each transaction from how many nodes it has received an "inv" for this transaction. This should, hopefully, give a rough idea of how far the transaction has spread thr
2206 2011-07-09 22:56:08 <jav__> ough the network.
2207 2011-07-09 22:58:11 <jav__> so far it seems to work fine... I'm mostly getting 97% to 100%, with an occasional 60-something thrown in (why could that be?)

2234 2011-07-09 23:27:18 <cuddlefish> I'd like a 'TX Broadcaster' service
2235 2011-07-09 23:27:34 <cuddlefish> and a RPC call to dump a new, signed transaction
2236 2011-07-09 23:28:11 <jav__> cuddlefish: the broadcaster would just blast the tx out to lots of nodes?
2237 2011-07-09 23:28:12 <tcatm> why use a service when you can broadcast it yourself?
2238 2011-07-09 23:28:40 <justmoon> tcatm, webcoin uses a broadcaster service because it doesn't have network connectivity itself for example
2239 2011-07-09 23:29:18 <cuddlefish> jav__: yeah
2240 2011-07-09 23:29:33 <tcatm> yes, but generally it's not a good idea to centralize bitcoin when we have a p2p network

2242 2011-07-09 23:29:48 <justmoon> also a specialized broadcaster could get connections to all the pools directly
2243 2011-07-09 23:30:04 <justmoon> and then make a double spend a lot less likely
2244 2011-07-09 23:30:05 <cuddlefish> tcatm: not a website or something, an API call
2245 2011-07-09 23:30:09 <cuddlefish> dumptx and loadtx maybe
2246 2011-07-09 23:30:18 <justmoon> dumptx and loadtx?
2247 2011-07-09 23:30:32 * tcatm (and a few others) are working on decentralized pools so that shouldn't be a big problem soon
2248 2011-07-09 23:30:33 <cuddlefish> dumptx takes same parameters as sendmany, but returns a base64-encoded transaction

2251 2011-07-09 23:30:38 <jav__> I don't think it's very helpful in combating double spends to broadcast it alot... you can't tell whether the nodes have accepted it anyway. I think it's better to be fairly "quiet" and have a chance and detecting conflicting transactions
2252 2011-07-09 23:30:41 <cuddlefish> loadTX broadcasts it
2253 2011-07-09 23:30:59 <justmoon> cuddlefish, I would call dumptx maketx and loadtx broadcasttx :)
