 21 2012-07-20 01:28:04 <jgarzik> luke-jr: did your patch solve the issue shown in the perf profile?
 22 2012-07-20 01:36:31 <luke-jr> jgarzik: well, if it's spending all its time in getblockhash, there was nothing to do in that regard
 23 2012-07-20 01:36:41 <luke-jr> but the patch does make it much faster
 24 2012-07-20 01:36:57 <luke-jr> (I mean, there was nothing else slowing it down much)
 25 2012-07-20 01:37:30 <luke-jr> it can do the whole chain in 2 minutes now
 26 2012-07-20 01:40:43 <jgarzik> luke-jr: you could always create a vector<> datastructure that allows immediate, direct indexing

 59 2012-07-20 02:30:01 <gmaxwell> I'm not aware of any reason why that would be different.. perhaps windows is gobbling the quotes and they need to be escaped in some other way.

149 2012-07-20 03:53:45 <MC1984> the length of the hash function affects chain size?
150 2012-07-20 03:54:28 <gmaxwell> yes, because it's full of hashes.
151 2012-07-20 03:55:00 <MC1984> the txn hashes are different
152 2012-07-20 03:56:18 <MC1984> i was not aware any of the mining hashes get stored in the chain, apart from the one that solves the block
153 2012-07-20 03:56:32 <MC1984> which would make 512 have a trivial effect on chain size
154 2012-07-20 03:56:44 <luke-jr> MC1984: the one solving the block is the only one that *isn't* stored
155 2012-07-20 03:57:13 <MC1984> the fuck.........
156 2012-07-20 03:57:27 <gmaxwell> MC1984: the previous hash is in the header, as well as the tree root hash. You'd basically double the base storage for low-storage node types.
157 2012-07-20 03:57:57 <MC1984> is luke trollin me
158 2012-07-20 03:58:00 <gmaxwell> headers only would go from 80 bytes to 144 bytes...
159 2012-07-20 03:58:28 <gmaxwell> MC1984: no. He's right, why would you store it? you have the block. Compute it, you must anyways to check it.
160 2012-07-20 04:00:55 <MC1984> where can i get an overview of what goes into a block
161 2012-07-20 04:01:05 <nanotube> ;;bc,wiki block hashing algo

163 2012-07-20 04:01:26 <MC1984> 144 bytes instead of 80 every 10 mins strikes me as trivial
164 2012-07-20 04:02:19 <nanotube> yes it is relatively trivial. but satoshi was worried about blockchain size a lot, in the early days.
165 2012-07-20 04:02:20 <MC1984> thanks nanotube
166 2012-07-20 04:02:51 <MC1984> well
167 2012-07-20 04:03:04 <MC1984> its damn trivial in the face of the txn volume pumping it up
168 2012-07-20 04:03:12 <MC1984> how about
169 2012-07-20 04:03:12 <gmaxwell> MC1984: but it's not trivial. A SPV node needs that data from the start of time to know it's on the right chain, and thats the only data it needs.
170 2012-07-20 04:03:34 <MC1984> lite node?
171 2012-07-20 04:06:29 <luke-jr> MC1984: the txn sizes would just about double too

182 2012-07-20 04:47:10 <weex> can a transaction have two or more outputs with the same address?
183 2012-07-20 04:47:46 <galambo_> do you think that would be an issue for some reason?
184 2012-07-20 04:47:58 <nanotube> i think that is not prohibited, weex
185 2012-07-20 04:48:20 <weex> well at coindl i've seen some transactions with more than one payment
186 2012-07-20 04:48:44 <weex> and i had been using the txid as a unique thing but i think i'll need to use the txid and address
187 2012-07-20 04:48:57 <gmaxwell> weex: it can, though its silly on typical transactions. I can probably concoct some crazy contract situation where it would be useful.
188 2012-07-20 04:49:01 <weex> then it occurred to me that even that pair might not be unique as real payments go
189 2012-07-20 04:49:10 <gmaxwell> weex: er, you need to use the txnid and output index. 0_o
190 2012-07-20 04:49:18 <copumpkin> yeah, that's what the protocol does anyway
191 2012-07-20 04:49:34 <weex> output index, eh?
192 2012-07-20 04:49:48 <copumpkin> weex: inputs are identified by txn id + output index
193 2012-07-20 04:50:00 <weex> would that be "block index"?
194 2012-07-20 04:50:09 <weex> blockindex that is
195 2012-07-20 04:50:11 <copumpkin> no
196 2012-07-20 04:50:31 <copumpkin> the outputs of a transaction are ordered in the transaction structure
197 2012-07-20 04:50:34 <copumpkin> the index is into that list
198 2012-07-20 04:50:57 <gmaxwell> A transaction can have multiple outputs. A particular output is uniquely identified by the transaction id and which output in the transaction you're referring to.
199 2012-07-20 04:51:22 <weex> which output meaning this integer index into the list?
200 2012-07-20 04:52:19 <galambo_> see the structure of CTxIn
201 2012-07-20 04:52:30 <copumpkin> weex: yeah
202 2012-07-20 04:53:10 <weex> is bitcoind going to give me that somehow... gettransaction maybe?
203 2012-07-20 04:53:16 <copumpkin> not sure
204 2012-07-20 04:54:15 <gmaxwell> weex: ah, if you're just talking about bitcoind, the list transaction output will throw out a new entry for each transaction destined to you.
205 2012-07-20 04:54:51 <gmaxwell> None of the fields distinguish them in that case.
206 2012-07-20 04:54:56 <weex> gmaxwell: i see that, and i think i'm fine just using txid and address as a unique pairing
207 2012-07-20 04:55:11 <gmaxwell> arguably the index should be stuck on the end of the txid for those recieved transactions.
208 2012-07-20 04:55:20 <gmaxwell> weex: you can't assume that.
209 2012-07-20 04:55:49 <galambo_> it contains a COutPoint
210 2012-07-20 04:56:12 <galambo_> COutPoint is... a hash and an integer
211 2012-07-20 04:56:17 <weex> i see no index on listtransactions
212 2012-07-20 04:56:25 <copumpkin> magic
213 2012-07-20 04:56:25 <galambo_> the subject of discussion is that integer
214 2012-07-20 04:56:26 <gmaxwell> I just said it wasn't there.
215 2012-07-20 04:56:44 <weex> arguably heh
216 2012-07-20 04:57:12 <gmaxwell> I meant that it ought to do it; it doesn't.
217 2012-07-20 04:58:02 <weex> if this is a ploy to make me want to work on bitcoind, it just might work
218 2012-07-20 04:58:34 <gmaxwell> Well, at least it should be a trivial change. For compatiblity the index should probably end up in another field. :(
219 2012-07-20 04:59:31 <galambo_> well it would seem to be an issue of semantics (you are asking for a list of transctions not a list of transaction outputs)
220 2012-07-20 05:00:34 <gmaxwell> galambo_: List transactions lists each output which belongs to you separately.
221 2012-07-20 05:00:58 <weex> so would it not then add together outputs to the same address?
222 2012-07-20 05:01:18 <weex> or just keep listing more of them
223 2012-07-20 05:01:42 <gmaxwell> I would be surprised if it did that, but I'd have to go actually hack up a client to generate such a txn.
224 2012-07-20 05:01:51 <gmaxwell> (surprised if it combined them)
225 2012-07-20 05:01:56 <galambo_> not sure thats not in my domain. i havent really looked at wallet/rpc stuff very hard yet

227 2012-07-20 05:03:24 <gmaxwell> weex: ones send to different address of yours absolutely are shown distinctly: http://pastebin.mozilla.org/1709092
228 2012-07-20 05:03:36 <weex> Armory was what generated the transactions that i ran into
229 2012-07-20 05:03:58 <weex> yeah different addresses are no problem
230 2012-07-20 05:04:02 <copumpkin> weex: the protocol doesn't really know about addresses, as far as I know?
231 2012-07-20 05:04:11 <gmaxwell> copumpkin: right.
232 2012-07-20 05:04:17 <gmaxwell> should just take commenting out the duplicate check on sendmany to test it.
233 2012-07-20 05:04:38 <copumpkin> weex: which is why it doesn't make much sense to do address-centric operations on transactions
234 2012-07-20 05:05:09 * gmaxwell compiles
235 2012-07-20 05:05:49 <weex> copumpkin: you mean like checking of money went to an address or..what do you mean?
236 2012-07-20 05:05:55 <weex> if*
237 2012-07-20 05:06:25 <copumpkin> weex: addresses just happen to be a layer of meaning encoded within scripts in the protocol
238 2012-07-20 05:06:35 <gmaxwell> weex: as expected: http://pastebin.mozilla.org/1709093
239 2012-07-20 05:06:50 <copumpkin> bitcoin could support other weirder types of transactions that don't really use addresses in the same way, I think, or don't use addresses at all
240 2012-07-20 05:07:28 <weex> gmaxwell: so that means as long as i keep track of how many { } blocks listtransactions shows i'll be ok?
241 2012-07-20 05:07:32 <copumpkin> would it be possible, for example (if people relayed weird transactions), to make a "free-for-all" transaction?
242 2012-07-20 05:08:22 <gmaxwell> weex: you could do that, I suppose. I think it would be safer to add the actual txout index to the json output. If you submit a pull request that does that I'll review it right away.
243 2012-07-20 05:08:34 <copumpkin> if I send to an output that had a "return true" script in it?
244 2012-07-20 05:09:18 <copumpkin> oh, is that how fees are implemented?
245 2012-07-20 05:09:21 <gmaxwell> copumpkin: sure, it's possible to make free for all txn.. but it really means free to luke.
246 2012-07-20 05:09:26 <copumpkin> lol
247 2012-07-20 05:09:27 <gmaxwell> Because he's running code to capture all those!
248 2012-07-20 05:09:39 <gmaxwell> (and has previously captured some)
249 2012-07-20 05:09:53 <copumpkin> I could also encode other problems into my scripts, I guess
250 2012-07-20 05:10:00 <copumpkin> that might require human interaction

253 2012-07-20 05:10:12 <gmaxwell> sure, there are hash locked txn in the chan, and lots of good uses for them too.
254 2012-07-20 05:10:36 <copumpkin> pushdata "What is the name of a colimit of a diagram a => c", check hash "blakaletay"
255 2012-07-20 05:10:41 <copumpkin> something like that
256 2012-07-20 05:11:01 * copumpkin hasn't actually experimented with script yet

259 2012-07-20 05:13:14 <gmaxwell> weex: I'm sure the script will work just as well for a version with a few lines changed. :) But issues are good too, though patches are better.

261 2012-07-20 05:17:33 <copumpkin> is there a page on how exactly the merkle hash is computed (from which fields, in what kind of nesting, and so on)?
262 2012-07-20 05:17:36 <copumpkin> or do I just need to read some code?
263 2012-07-20 05:17:55 <copumpkin> the protocol rules just say "verify merkle hash"

583 2012-07-20 21:02:47 <gmaxwell> Transactions which were sent to scripts which can not possibly be represented as an address.
584 2012-07-20 21:04:34 <phantomcircuit> also it's a bad idea to assume that the sending address is a valid return address
