188 2016-07-22T17:26:48  <achow101> I'm doing some stuff for segwit with Armory, and one part of it is sending a getdata message to bitcoin core about a transaction that it just sent. The transaction was clearly accepted by core (I see it in the transaction list) but it keeps returning a notfound message. Any reason why?
189 2016-07-22T17:28:32  <sipa> achow101: is this only for segwit, or generally true?
190 2016-07-22T17:29:11  <sipa> achow101: is this from the same node that sent the transaction?
191 2016-07-22T17:29:22  <achow101> I think it is only for segwit, I haven't seen this behavior anywhere else, but I'm not sure
192 2016-07-22T17:29:38  <sipa> there have been significant changes to tx relay in 0.13
193 2016-07-22T17:29:50  <sipa> you can only query for transactions now after they've been inved to you for privacy reasons
194 2016-07-22T17:30:01  <sipa> but if you're the sender yourself that doesn't make much sense
195 2016-07-22T17:30:41  <achow101> no, Armory is the sender. It connects as another node. It sends the transaction then asks for it back to check that it was accepted

199 2016-07-22T17:37:32  <sipa> achow101: if you wait a few seconds, that should work
200 2016-07-22T17:37:47  <achow101> how so?
201 2016-07-22T17:37:55  <sipa> can you test whether that's the case?
202 2016-07-22T17:38:07  <achow101> I can try
203 2016-07-22T17:38:20  <sipa> we delay inserting the transaction into the relay pool until we actually relay it somewhere
204 2016-07-22T17:38:29  <sipa> but there is a randomized delay before that happens
205 2016-07-22T17:39:26  <sipa> it's probably easier to check for a reject message instead...
206 2016-07-22T17:40:17  <achow101> what is the longest the randomized delay can be?
207 2016-07-22T17:40:33  <sipa> infinity
208 2016-07-22T17:40:36  <sipa> it's poisson distributed
209 2016-07-22T17:40:40  <achow101> great...
210 2016-07-22T17:40:45  <sipa> but on average it's 5 to 10 seconds
211 2016-07-22T17:42:27  <sipa> as an alternative, you can send a ping after the getdata, and if the pong returns before you get a reject message, the transaction is accepted
212 2016-07-22T17:43:17  <sipa> or even better, check whether _other_ peers inv the transaction back to you
213 2016-07-22T17:43:38  <sipa> that way you can actually see whether it propagated across the network

229 2016-07-22T18:33:00  <CodeShark> talking to the author now
230 2016-07-22T18:34:46  <gmaxwell> stab stab stab
231 2016-07-22T18:35:22  <gmaxwell> cfields: I am currently compiling old versions and it is reminding me to thank you for all the wonderful things you did to the build process.
232 2016-07-22T18:35:48  <cfields> heh
233 2016-07-22T18:35:57  <cfields> building pre-0.7?
234 2016-07-22T18:37:17  <sipa> i tried building 0.3.x a while ago
235 2016-07-22T18:37:21  <sipa> that was painful.
236 2016-07-22T18:39:29  <sipa> it's probably fair to say that ever since the concept of backward compatible consensus changes was invented (now called soft forks), bitcoin has not had any hard forks (apart from potentially the march 2013 one, but that's dubious)
237 2016-07-22T18:40:05  <sipa> and bitcoin 0.2.10 should be able to sync the full chain (due to a p2p change in 0.2.10)
238 2016-07-22T18:40:24  <gmaxwell> Trying to compile 0.2.10 right now... in wxhell
239 2016-07-22T18:41:02  <gmaxwell> doing earlier is possible, I synced the _original_ release up to the current chain last sometime in 2013 I believe, but its a PITA due to the p2p proto change.

253 2016-07-22T19:04:49  <gmaxwell> I was working on it two hours ago actually, before seeing that fool article.
254 2016-07-22T19:05:04  <gmaxwell> because of some other person repeating the same claim elsewhere.

272 2016-07-22T20:58:36  <gmaxwell> interesting failure mode, user manages to manually create a zero fee txn for something where they don't care if takes forever...
273 2016-07-22T20:58:41  <gmaxwell> then we spend the unconfirmed change.
274 2016-07-22T20:58:53  <gmaxwell> and then they're unhappy wth all their txn stuck.
275 2016-07-22T21:02:24  <sipa> gmaxwell: cpfp!
276 2016-07-22T21:02:42  <luke-jr> ^
277 2016-07-22T21:02:44  <sdaftuar> if it was literally zero fee, cpfp probably won't help
278 2016-07-22T21:02:51  <luke-jr> sdaftuar: why not?
279 2016-07-22T21:02:57  <sdaftuar> limited mempools
280 2016-07-22T21:02:59  <luke-jr> oh, no relay cpfp yet?
281 2016-07-22T21:03:18  <sdaftuar> this is really made for RBF
282 2016-07-22T21:03:37  <luke-jr> yes, it's better to respend with an additional output than to create a child
283 2016-07-22T21:04:04  <gmaxwell> I'm helping this guy compute a replacement.
284 2016-07-22T21:04:18  <gmaxwell> none of this stuff is relaying, so easy to get mined.
285 2016-07-22T21:04:20  <luke-jr> somehow I suspect the wallet logic doesn't calculate fees with unconfirmed inputs taken into consideration :x
286 2016-07-22T21:04:27  <luke-jr> probably not a show-stopper
287 2016-07-22T21:04:45  <gmaxwell> well we should probably have a thing like not spending unconfirmed unputs where it won't spend change with fees to low to relay now.
288 2016-07-22T21:06:11  <luke-jr> we already don't spend unconfirmed change when it's possible to avoid it

298 2016-07-22T21:37:02  <gmaxwell> luke-jr: kinda! so say you have two unconfirmed outputs, one has no low fee ancestor in its unconfirmed history.
299 2016-07-22T21:37:05  <gmaxwell> The other does.
300 2016-07-22T21:37:09  <gmaxwell> We'll spend both of those equally.
301 2016-07-22T21:37:34  <gmaxwell> similarly for long chains of unconfirmed transactions.. we'll spend a unconfirmed coin at depth 25 even when there is one at depth 1 available.
