125 2013-07-11 01:55:22 <The_Fly> i can import about 30 privkeys/sec with bitcoind on an ebs optimised instance
126 2013-07-11 01:55:38 <warren> ebs?
127 2013-07-11 01:55:41 <The_Fly> and getnewaddress is a bit faster

130 2013-07-11 01:56:25 <The_Fly> i suppose these speeds are better but still would not scale well unless i pregenerate a lot of addresses
131 2013-07-11 01:56:56 <The_Fly> but then again, i am going to encourage users to spend off-blockchain and instead deposit for a balance
132 2013-07-11 01:57:01 <warren> using the import key birthdate patch?
133 2013-07-11 01:57:13 <The_Fly> does that speed things up?
134 2013-07-11 01:57:16 <warren> yes
135 2013-07-11 01:57:21 <The_Fly> i heard something about it, ok
136 2013-07-11 01:57:26 <The_Fly> significantly?

150 2013-07-11 02:04:33 <The_Fly> assuming that bitcoind has already checked that the inputs are unspent
151 2013-07-11 02:04:53 <The_Fly> (currently it announces them when they're first seen, and on first confirmation)

154 2013-07-11 02:08:33 <warren> The_Fly: IIRC that patch requires keys with a new thing added for the birthdate
155 2013-07-11 02:08:43 <warren> The_Fly: so it avoids scanning before the birthday
156 2013-07-11 02:08:53 <warren> bbl
157 2013-07-11 02:08:58 <The_Fly> but im not asking it to scan
158 2013-07-11 02:09:08 <The_Fly> with importprivkey
159 2013-07-11 02:09:16 <The_Fly> and if getnewaddress scans, that's just silly
160 2013-07-11 02:09:47 <The_Fly> it's perhaps RPC that's the bottleneck now
161 2013-07-11 02:09:53 <phantomcircuit> The_Fly, why are you importing keys?
162 2013-07-11 02:10:04 <The_Fly> phantomcircuit: i have a bunch of coldstorage keys i want to use
163 2013-07-11 02:10:29 <phantomcircuit> so it's a once off import?
164 2013-07-11 02:10:34 <The_Fly> yes
165 2013-07-11 02:10:44 <phantomcircuit> then who cares
166 2013-07-11 02:10:45 <The_Fly> and once the transaction is done, bitcoind doesn't really need the key
167 2013-07-11 02:11:05 <The_Fly> phantomcircuit: because the rate of 30/sec is not great if you have 100s/sec
168 2013-07-11 02:11:18 <phantomcircuit> but you just said it's once off
169 2013-07-11 02:11:18 <The_Fly> so i can pregenerate some and serve them a different way
170 2013-07-11 02:11:34 <The_Fly> phantomcircuit: its once off per user, per transaction
171 2013-07-11 02:11:42 <phantomcircuit> that's not once off
172 2013-07-11 02:11:53 <The_Fly> ok, its not a once off import
173 2013-07-11 02:11:58 <The_Fly> i thought that was obvious!
174 2013-07-11 02:12:00 <The_Fly> ...
175 2013-07-11 02:12:08 <The_Fly> otherwise why am i talking about rates?
176 2013-07-11 02:12:22 <phantomcircuit> i assumed because you're impatient
177 2013-07-11 02:12:24 <The_Fly> getnewaddress similarly runs about 30/sec
178 2013-07-11 02:12:25 <phantomcircuit> which i am as well
179 2013-07-11 02:12:28 <The_Fly> lol
180 2013-07-11 02:12:33 <The_Fly> hehe, no not in this case

182 2013-07-11 02:13:02 <phantomcircuit> The_Fly, what's the application, maybe i can think of a more efficient way to do it
183 2013-07-11 02:13:03 <The_Fly> i just shouldn't be this slow, and in this context it has to be RPC... no?
184 2013-07-11 02:13:44 <The_Fly> users click deposit, they get an address, they see the balance...
185 2013-07-11 02:14:02 <The_Fly> sometimes they may buy something, i dont want to keep funds on the server, so i use a queue of addresses
186 2013-07-11 02:14:06 <The_Fly> and the importaddress patch
187 2013-07-11 02:14:28 <The_Fly> in cases where i know they may not ask to cashout/withdraw
188 2013-07-11 02:14:32 <gmaxwell> The_Fly: I told you what your problem was earlier, I thought. You've got a really slow disk, anything that writes to the wallet is synchronous to avoid losing data ... soooo.
189 2013-07-11 02:14:38 <phantomcircuit> The_Fly, so you're assigning the address to the user and not to a specific transaction?
190 2013-07-11 02:14:51 <The_Fly> gmaxwell: and i told you that i went to test it on an ec2 ebs optimised instance
191 2013-07-11 02:14:54 <The_Fly> lol
192 2013-07-11 02:15:01 <The_Fly> and those are my results

195 2013-07-11 02:15:48 <The_Fly> phantomcircuit: it gets assigned to a transaction yes
196 2013-07-11 02:16:16 <The_Fly> so im thinking yes, i could do it outside bitcoind, but the question then is to ascertain #confs for a given transaction
197 2013-07-11 02:16:23 <phantomcircuit> The_Fly, so it's per transaction and not per user?
198 2013-07-11 02:16:34 <The_Fly> its per transaction, the balance updates are per user
199 2013-07-11 02:16:38 <The_Fly> its a bit of both, see.
200 2013-07-11 02:16:45 <phantomcircuit> oh
201 2013-07-11 02:16:48 <The_Fly> yes
202 2013-07-11 02:16:50 <The_Fly> gmaxwell: ...

206 2013-07-11 02:16:56 <The_Fly> thats getnewaddress
207 2013-07-11 02:17:02 <phantomcircuit> so everytime they click the button they get a new address?
208 2013-07-11 02:17:06 <The_Fly> and timings are similar for importprivkey
209 2013-07-11 02:17:10 <phantomcircuit> that's not going to work for very long
210 2013-07-11 02:17:11 <The_Fly> phantomcircuit: yes
211 2013-07-11 02:17:22 <phantomcircuit> you'll have millions of active keys in no time
212 2013-07-11 02:17:33 <phantomcircuit> 99% of which wont be tied to a transaction
213 2013-07-11 02:17:50 <gmaxwell> The_Fly: what are you talking about here?
214 2013-07-11 02:18:54 <The_Fly> phantomcircuit: which is the nice thing about getaccountaddress
215 2013-07-11 02:19:25 <The_Fly> as they only advance when the last received a tx
216 2013-07-11 02:19:25 <gmaxwell> The_Fly: You're on a disk with an access time over >10ms, you're not going to get a sync write to the wallet to be faster than that.
217 2013-07-11 02:19:29 <phantomcircuit> do NOT use the account feature
218 2013-07-11 02:19:35 <phantomcircuit> it's impossible to maintain backups
219 2013-07-11 02:19:39 <The_Fly> gmaxwell: im running this on an ec2 instance now
220 2013-07-11 02:19:45 <The_Fly> ive said that twice now
221 2013-07-11 02:19:55 <The_Fly> not on shitty laptop hd
222 2013-07-11 02:20:05 <turboroot> The_Fly: lol ebs
223 2013-07-11 02:20:07 <lianj> you think ec2 is fast=?
224 2013-07-11 02:20:10 <gmaxwell> The_Fly: uh, it's not like EC2 has fast storage. dear god.
225 2013-07-11 02:20:30 <phantomcircuit> The_Fly, on a real server with an ssd i can do ~200 per second
226 2013-07-11 02:20:41 <The_Fly> thats better but still..
227 2013-07-11 02:20:42 <gmaxwell> Instead you've got a 5000 RPM GREEN disk connected over a network block device or something equally horiffic.
228 2013-07-11 02:21:11 <turboroot> cpu is equally as bad
229 2013-07-11 02:21:39 <The_Fly> indeed, but i've no experience working with dedicated servers
230 2013-07-11 02:21:45 <turboroot> but that has little effect here afaik
231 2013-07-11 02:21:47 <The_Fly> nor do i know if i can afford one good enough
232 2013-07-11 02:22:03 <phantomcircuit> The_Fly, nobody needs 200 new addresses per second
233 2013-07-11 02:22:09 <The_Fly> no, that's right
234 2013-07-11 02:22:11 <phantomcircuit> if you do then you need to change how your system works
235 2013-07-11 02:22:14 <The_Fly> and if i did i would buffer them
236 2013-07-11 02:22:16 <gmaxwell> In any case, if you're worried about being able to sustain 50 payments per second then... well thats a good problem to have.
237 2013-07-11 02:22:29 <The_Fly> actually id like not to,
238 2013-07-11 02:22:39 <gmaxwell> Especially since the entire bitcoin network can't sustain that kind of transaction volume...
239 2013-07-11 02:22:40 <The_Fly> do not want to be accused of blockchain spam ;)
240 2013-07-11 02:23:03 <phantomcircuit> gmaxwell, he's thinking that everytime someone clicks the "deposit" button they'll get a new address
241 2013-07-11 02:23:15 <The_Fly> which doesn't have to be the case
242 2013-07-11 02:23:15 <gmaxwell> phantomcircuit: sure and?
243 2013-07-11 02:23:18 dparrish has joined
244 2013-07-11 02:23:25 <The_Fly> especially considering getaccountaddress helps me here
245 2013-07-11 02:23:41 <phantomcircuit> The_Fly, the "right" way to do this is to assign addresses to users and expire the address when you see any transaction which pays to that address
246 2013-07-11 02:23:53 <The_Fly> sure, which is what getaccountaddress does.
247 2013-07-11 02:24:01 <The_Fly> right??
248 2013-07-11 02:24:07 <phantomcircuit> i dont think so
249 2013-07-11 02:24:19 <turboroot> The_Fly: i would not use bitcoin's accounts for accounting
250 2013-07-11 02:24:19 <gmaxwell> The_Fly: and if you glitch your wallet and restore from a backup you'll be giving out user A's address to user C.
251 2013-07-11 02:24:21 <The_Fly> it behaved as you just described last time i checked
252 2013-07-11 02:24:37 <gmaxwell> phantomcircuit: it does, but see my comment.
253 2013-07-11 02:24:41 <phantomcircuit> yeah it does
254 2013-07-11 02:24:52 <phantomcircuit> gmaxwell, yup that's exactly the issue
255 2013-07-11 02:24:54 <The_Fly> yeah, so avoiding that case would be good gmaxwell
256 2013-07-11 02:25:07 <The_Fly> and i was hoping not to need to use bitcoind's for accounting at all
257 2013-07-11 02:25:17 <gmaxwell> The_Fly: so don't.
258 2013-07-11 02:25:22 <The_Fly> i wont.
259 2013-07-11 02:25:41 B0g4r7 has joined
260 2013-07-11 02:26:07 <phantomcircuit> The_Fly, do as i said, emulate the behavior of the getaccountaddress rpc call but maintain the user -> address mapping in a proper database
261 2013-07-11 02:26:44 <The_Fly> yeah that works fine if i want to avoid dead/useless keys in my wallet
262 2013-07-11 02:26:45 <phantomcircuit> it's really not that hard to do
263 2013-07-11 02:26:56 <The_Fly> i know, the issue is just the rate i can import them
264 2013-07-11 02:27:03 <phantomcircuit> The_Fly, believe me that is your #1 goal performance wise
265 2013-07-11 02:27:12 <The_Fly> i do believe you
266 2013-07-11 02:27:18 <The_Fly> i asked about removing keys
267 2013-07-11 02:27:18 <phantomcircuit> The_Fly, import what?
268 2013-07-11 02:27:25 <The_Fly> the coldstorage keys
269 2013-07-11 02:27:31 <phantomcircuit> why would you be removing keys
270 2013-07-11 02:27:32 <The_Fly> sorry... just addresses
271 2013-07-11 02:28:08 <phantomcircuit> i still dont get what the issue is
272 2013-07-11 02:28:29 <phantomcircuit> you pull a ton of keys into your db with the user -> address mapping and keep the user field NULL
273 2013-07-11 02:28:29 <The_Fly> that via the rpc call the rate i can import addresses is slow
274 2013-07-11 02:28:41 <phantomcircuit> then assign addresses to users when they need one from the pool in the db
275 2013-07-11 02:28:44 <phantomcircuit> without touching rpc
276 2013-07-11 02:28:49 <The_Fly> ok, so thats the pregeneration solution
277 2013-07-11 02:28:54 <The_Fly> which i mentioned
278 2013-07-11 02:29:00 <The_Fly> and am considering
279 2013-07-11 02:29:00 <gmaxwell> The_Fly: again, if you're running into problems where 50 transactions per second is an issue for you, you can afford some hardware where it isn't.
280 2013-07-11 02:29:05 <phantomcircuit> your peak load might be 30/second
281 2013-07-11 02:29:10 <The_Fly> right now i am not running into that issue
282 2013-07-11 02:29:17 <phantomcircuit> but your sustained average load will me more like 30/hour if you're lucky
283 2013-07-11 02:29:18 <The_Fly> but with what id like to set up, maybe i could
284 2013-07-11 02:29:40 <The_Fly> true, very true
285 2013-07-11 02:29:46 <The_Fly> it's at least good to think about these problems though
286 2013-07-11 02:29:54 <phantomcircuit> often not really
287 2013-07-11 02:30:01 <gmaxwell> or you could just run bitcoin with eatmydata or whatever and it'll probably be fast, though any crash will corrupt your wallet.
288 2013-07-11 02:30:11 <phantomcircuit> if it's actually an issue you'll be able to simply run multiple bitcoind instances
289 2013-07-11 02:30:24 <gmaxwell> phantomcircuit: well, less not reall when you're just outsourcing the thinking to suckers on IRC. :P
290 2013-07-11 02:30:38 <phantomcircuit> gmaxwell, shrug
291 2013-07-11 02:30:46 <phantomcircuit> the hard part is implementing it correctly
292 2013-07-11 02:30:54 <phantomcircuit> bugs bugs everywhere
293 2013-07-11 02:30:58 <The_Fly> gmaxwell: oi, im consulting with experts :P
294 2013-07-11 02:31:11 <The_Fly> yes phantomcircuit multiple instances is another solution, not a nice one
295 2013-07-11 02:31:16 <The_Fly> and hopefully not necessary for long
296 2013-07-11 02:31:17 <phantomcircuit> anyways im just sitting here waiting for stuff to compile
297 2013-07-11 02:31:40 <phantomcircuit> gmaxwell, lol it's 7pm i was about to say "shouldn't you be at work" but no
298 2013-07-11 02:32:24 <gmaxwell> I am, you note that I've only commented a bit... and mostly to say "didn't I tell you before what your issue is." :P
299 2013-07-11 02:32:59 <The_Fly> i think if microtransactions are supposed to be a big use-case for bitcoin those kinds of rates should be considered, perhaps not for a single project... but im experimenting with building merchant tools
300 2013-07-11 02:33:06 <gmaxwell> The_Fly: running multiple daemons is a perfectly reasonable thing to do generally.
301 2013-07-11 02:33:15 <The_Fly> if you want to scale to an arbitrary number of merchants it may have to scale to 50/sec
302 2013-07-11 02:33:33 <phantomcircuit> microtransactions on the network just dont work very well
303 2013-07-11 02:33:41 <The_Fly> ok sure, but even still
304 2013-07-11 02:33:51 <phantomcircuit> but most people are ok with risking $10 to some third party they dont really trust

317 2013-07-11 02:36:42 <The_Fly> pigeons: it's not complete, as you can see :)
318 2013-07-11 02:36:47 <sipa> gmaxwell: btw, technically we don't need a sync for every new address
319 2013-07-11 02:37:14 <phantomcircuit> sipa, is there something that detects whether keypool addresses have been used?
320 2013-07-11 02:37:17 <sipa> gmaxwell: that can happen in the background after the keypool is topped up afaim
321 2013-07-11 02:37:22 <gmaxwell> sipa: If we're to have zero risk of double issuing after a crash, though god knowsâ I dunno if we even provide that now.
322 2013-07-11 02:37:48 <gmaxwell> I suppose we could prereserve and just lose those addresses if we crash.
323 2013-07-11 02:37:52 <sipa> gmaxwell: i doubt we can provide that
324 2013-07-11 02:38:00 <The_Fly> it seems reasonable
325 2013-07-11 02:38:01 <sipa> phantomcircuit: not afaik
326 2013-07-11 02:38:08 <gmaxwell> The_Fly: what seems reasonable?
327 2013-07-11 02:38:24 <sipa> but for bip32 we'll need that
328 2013-07-11 02:38:38 <The_Fly> not syncing just address import

334 2013-07-11 02:39:26 <gmaxwell> The_Fly: well it means that if bitcoin crashes you may think it has things imported which it doesn't. And it's not obvious that it doesn't. So you'll miss transactions.

337 2013-07-11 02:39:49 <michagogo> What does it mean?
338 2013-07-11 02:39:52 <The_Fly> if it's already gone to the user yes
339 2013-07-11 02:40:00 <The_Fly> phantomcircuit: yes but running in serial means im waiting for rpc connections to open and close
340 2013-07-11 02:40:05 <sipa> it's a typo for afaik
341 2013-07-11 02:40:06 <gmaxwell> The_Fly: likewise for getnewaddressâ you'll give out the same address multiple times. Meaning you'll need an accounting layer on top to filter that out, and if you've done that, the performance should be irrelevant since you could just precompute and have it do the assignment.
342 2013-07-11 02:40:08 <michagogo> Ah

347 2013-07-11 02:40:46 <phantomcircuit> gmaxwell, which is exactly what i suggested he do :)
348 2013-07-11 02:40:56 <The_Fly> i shall try using a client rather than from bitcoind on the shell
349 2013-07-11 02:40:57 <phantomcircuit> it's a lot easier to keep something like postgresql consistent
350 2013-07-11 02:41:02 <gmaxwell> yea, good advice.
351 2013-07-11 02:41:19 <gmaxwell> well the databases actually have formal support for replication and such, so yea. duh. :P
352 2013-07-11 02:41:41 <The_Fly> id be fine with keeping addresses in postgres, ive been experimenting with that
353 2013-07-11 02:41:52 <The_Fly> but had been pulling them out, importing them to bitcoind, then issuing
354 2013-07-11 02:42:22 <The_Fly> prepopulating a database from getnewaddress is good, that works

479 2013-07-11 03:28:37 <gmaxwell> sort of a bit surprised to see that listtransactions on a wallet with generated coins shows them as orphan when it hasn't caught up to the blocks containing them.
480 2013-07-11 03:30:42 <sipa> gmaxwell: hmm, what would you suggest?
481 2013-07-11 03:30:55 ielo has joined
482 2013-07-11 03:34:25 <gmaxwell> I would not have expected _orphan blocks_ to hit the wallet. Extinct ones (with orphan coinbases). There is actually a DOS attack here, I think.

484 2013-07-11 03:35:07 <gmaxwell> e.g. I could send you orphan diff 1 blocks with 1mb coinbase txns paying you and add data to your wallet.
485 2013-07-11 03:35:22 <gmaxwell> er I'd expect extinct ones to hit it but not unconnected ones.
486 2013-07-11 03:35:46 <gmaxwell> Not a serious DOS attack, at least.

503 2013-07-11 03:55:09 <sipa> gmaxwell: "orphan" for transactions means that the generating transaction is not in the best chain
504 2013-07-11 03:55:33 <sipa> gmaxwell: that is the cause for the confusing in terminology
505 2013-07-11 03:55:54 <sipa> the blocks are not orphan, but their coinbases are
506 2013-07-11 03:56:20 <sipa> orphan blocks (in the proper meaning of orphan) never hit the wallet
507 2013-07-11 03:57:06 <gmaxwell> sipa: but these are orphan blocks, afaict.
508 2013-07-11 03:57:37 <gmaxwell> I'm resyncing a node from 0, and there are some totally valid new generations from today that are orphan blocks because I haven't caught up to them yet
509 2013-07-11 03:57:46 <gmaxwell> and they were added to the wallet as "orphan"
510 2013-07-11 03:58:50 <gmaxwell> "blocks" : 224197,
511 2013-07-11 03:59:03 <gmaxwell> "category" : "orphan",
512 2013-07-11 03:59:07 <gmaxwell> "txid" : "6900ce2c2f106d7187818f0bb226fb5ab3311fe5c8df7618bca2d538e5b9d1a5",
513 2013-07-11 03:59:17 <gmaxwell> which is block 245900

527 2013-07-11 04:19:20 <sipa> but it's just a block that doesn't exist at all
528 2013-07-11 04:19:30 <sipa> yet the transaction is in the wallet
529 2013-07-11 04:19:41 <sipa> so the transaction is orphaned
530 2013-07-11 04:19:55 <sipa> regardless of the reason why the block can't be found
531 2013-07-11 04:22:12 <sipa> but real orphan blocks (lone received blocks) are not processed until their oarents are connected, so won't trigger an add to fhe wallet
532 2013-07-11 04:23:02 <gmaxwell> Then how did this transaction end up added to my wallet? My node has only synced to 224197. That txn is block 245900â its parents aren't connected yet.
533 2013-07-11 04:23:52 <sipa> i assume the wallet has seen a later blockchain db
534 2013-07-11 04:25:47 <gmaxwell> It had seen later than 224197. But it had not seen 245900 or 245899 unless I'm timezone confused.
535 2013-07-11 04:26:11 <sipa> i see no other explanation

571 2013-07-11 05:09:57 <gjs278> what do you need multiple instances of bitcoind for
572 2013-07-11 05:10:07 <sipa> huge wallets
573 2013-07-11 05:10:15 <sipa> unfortunately
574 2013-07-11 05:10:31 xenland has joined
575 2013-07-11 05:11:07 <gjs278> so if I gen like 1m vanity addresses on my personal wallet, I'd have major issues keeping up with rpc commands?
576 2013-07-11 05:11:15 <TradeFortress> Scrat, yeah, I'm going to do that until it's no longer feasible. I'll then start sharding
577 2013-07-11 05:11:34 <gjs278> and what holds it back, cpu or io at that point
578 2013-07-11 05:11:38 <TradeFortress> somehow I corrupted a wallet.dat copied between servers. hmm.
579 2013-07-11 05:11:38 <sipa> gjs278: that'll mostly just slowdown startup
580 2013-07-11 05:11:54 <sipa> TradeFortress: different versions?
581 2013-07-11 05:11:54 <TradeFortress> it's transactions that matter apparently
582 2013-07-11 05:12:17 <TradeFortress> sipa, all v0.8.3 through I did accidently run v0.3 something once on that wallet.dat. will copy it again
583 2013-07-11 05:12:17 <sipa> TradeFortress:was the source bitcoind running?
584 2013-07-11 05:12:24 <TradeFortress> no, shut it down first
585 2013-07-11 05:12:27 <sipa> ok
586 2013-07-11 05:12:39 <gjs278> what kills the performance, cpu or io for the huge wallets
587 2013-07-11 05:12:59 <TradeFortress> gjs278, pretty sure IO. cause it's just looking things up
588 2013-07-11 05:13:08 <sipa> well rpc itself is limited because of tcp connection setup
589 2013-07-11 05:13:29 <gjs278> if it's io... how big can a wallet.dat even get
590 2013-07-11 05:13:42 <sipa> anything balance related is O(n) in the number of transactions
591 2013-07-11 05:14:03 <gjs278> how big does your wallet.dat have to be filesize wise to give you trouble
592 2013-07-11 05:14:15 <sipa> and any wallet modification needs a sync of the wallet to disk, limited by io speed
593 2013-07-11 05:14:29 <sipa> the size of the wallet doesn't really matter for that

597 2013-07-11 05:15:07 <sipa> not really the wallet being large itself
598 2013-07-11 05:15:38 <sipa> though at some point

602 2013-07-11 05:16:10 <gjs278> well... if it's really disk stuff there are ways around that, like raiding1 mdadm to a ramdisk and delaying the write on the hard disk for a good minute

609 2013-07-11 05:17:55 <Scrat> sharding would complicate everything including hot wallet management

869 2013-07-11 13:46:25 <asdsdqqwe> <asdsdqqwe> AlexNagy: i totally agree lost coins increase the value of non lost coins
870 2013-07-11 13:46:27 <asdsdqqwe> <asdsdqqwe> BTC has value because it has a limit on the amount of BTC. A limit which will never increase. Through lost coins, the total amount available for transactions will decrease, therefore increasing the value of the remaining supply. As long as BTC is a currency demand will remain the same or go up (or go down depending on the mood of the market) but the value will continue to increase as they become rarer.
871 2013-07-11 13:46:29 <asdsdqqwe> <asdsdqqwe> AlexNagy: i just don't see how lost coins are a "problem" that need to be "worried about", in short, they don't matter

875 2013-07-11 13:46:36 <asdsdqqwe> <asdsdqqwe> AlexNagy: bitcoin is also theoretically infinitely divisable
876 2013-07-11 13:46:38 <asdsdqqwe> <asdsdqqwe> AlexNagy: so its not like if too many get lost the whole thing will freeze up
877 2013-07-11 13:46:40 <asdsdqqwe> <asdsdqqwe> spreelanka: yes, you can. // epscy this is true but currently are only divisable into 100,000,000 units, right?

937 2013-07-11 14:28:27 <michagogo> And cut them loose (or at least have the client switch away from them for initial sync)

960 2013-07-11 14:37:38 <Michhell> or in an Iarplane?
961 2013-07-11 14:37:46 <sipa> in theory, yes, but it will be very slow
962 2013-07-11 14:38:22 <Michhell> if i print out the privat key. how many pages ar this?

1069 2013-07-11 17:04:04 <midnightmagic> I have two bitcoin nodes, A and B. They are fairly distant from one another--as far apart as east and west coast U.S. I would like to understand what's going on with the network between the two of them. Is there a single tool which semi-automatically measures the network characteristics between two endpoints? Say, exercises MTU, fiddles with TCP parameters, traceroutes to examine per-hop latencies (as much as possible) including
1070 2013-07-11 17:04:10 <midnightmagic> TCP, does icmp echo, tries to measure for buffer bloat issues, that sort of thing?

1074 2013-07-11 17:06:49 <gmaxwell> midnightmagic: the closest I'm aware of to what you're asking forâ in terms of benchmarkingâ is http://www.uperf.org/ or http://code.google.com/p/iperf/
1075 2013-07-11 17:07:39 <gmaxwell> Yea, mtr is pretty handy. Also, if you want long term latency/loss graphsâ I'm fond of smokeping.
1076 2013-07-11 17:08:30 <Ry4an> ooh, I run ping in a loop on a few links about which I worry. I'll have to look into that.

1078 2013-07-11 17:09:56 <gmaxwell> Ry4an: fping (which I think smokeping uses in the background) is pretty useful for "ping N things I care about"
1079 2013-07-11 17:11:05 <Ry4an> usually I'm fighting w/ ISPs about packetloss, so I do 10 pings every 2 minutes forever and graph the loss, but doing that w/ bash/grep feels like reinventing the wheel
1080 2013-07-11 17:11:41 <Ry4an> not that it's a complex wheel of course, but still nice to have something that handles the history/graphing for me.

1127 2013-07-11 18:34:03 <DoctorBTC> so, every 2 weeks or so I fire up bitcoin-qt on osx, only to find something corrupted or a crash on launch. I am now in the habit of backing up the entire 'Bitcoin' folder from 'Application Support'. Is this normal user behaviour?
1128 2013-07-11 18:34:42 <DoctorBTC> This morning it happened. I do recall that the client was catching up when I had to quit out of it a few days ago....
1129 2013-07-11 18:35:31 <DoctorBTC> btw, restoring my backup of the blockchain and all those files works like a charm, it just has to resync.

1137 2013-07-11 18:42:21 <DoctorBTC> gmaxwell: interesting. I know for sure that the last time I ran qt, it was syncing 2 days behind. I did 'File > quit' and it looked like it closed down nice.
1138 2013-07-11 18:43:21 <gmaxwell> Well, I did say 'most'. We don't know the cause and so there may be other cases. Its hard to get good informationâ I assume most people don't report it.

1142 2013-07-11 18:44:09 <gwillen> DoctorBTC: well, I have systemwide backups, too, so if it explodes I'll restore

1352 2013-07-11 21:07:30 <midnightmagic> There used to be treatises on the subject, but damned if I can find them now. Is there a list somewhere of all the different interesting classes of attacks that are commonly used, and explanations of typical defenses? There seems to be a tremendous amount of expertise rolled up in openssl, for example, but the expertise itself, while coded in the source, doesn't seem to be explicitly described.

1355 2013-07-11 21:08:23 <midnightmagic> By attacks I mean "buffer overflow," "off-by-1", "signed integer"..

1362 2013-07-11 21:10:32 <gmaxwell> midnightmagic: openssl is not particularly hardened against the things you've listed, except for timing attacks. In fact, it intentionally used undefined behavior.
1363 2013-07-11 21:11:15 <gmaxwell> In any case, you probably want the stuff listed on securecoding.cert.org

1366 2013-07-11 21:11:58 <midnightmagic> gmaxwell: But the exploits that it's corrected in its own code, encode some of the expertise required to fix them. But short of slogging slowly through external secunia/etc advisories, .. I think too many projects fix the issue and then sweep it under the rug, where people have a harder time learning from it when designing other software..
1367 2013-07-11 21:12:09 <midnightmagic> oo that's nice.
1368 2013-07-11 21:12:53 <gmaxwell> OpenSSL isn't the last place I'd recommend people look for defensive programming, but its close to it.

1495 2013-07-11 23:25:23 <eruadan> hi, i'm curious about btc code base)i just know some js), and i notice it has a lot of typescript. is there any particular reason that this language was chosen?
1496 2013-07-11 23:26:29 <lianj> typescript? WHERE
1497 2013-07-11 23:26:43 <lianj> ups, didn't want to capslock

1508 2013-07-11 23:31:32 <lianj> maybe the github stats are wrong due to https://github.com/bitcoin/bitcoin/tree/master/src/qt/locale

1519 2013-07-11 23:45:53 <K1773R> if i set the keypool to 1000 and find 1000 blocks, a backup would also work? ie does finding new blocks use an address from the keypool?
1520 2013-07-11 23:46:02 <K1773R> it should AFAIK

1526 2013-07-11 23:55:47 <Luke-Jr> getwork is deprecated, but behaves like that
1527 2013-07-11 23:55:55 <Luke-Jr> and bitcoind's GBT doesn't coordinate the payout at all
