176 2017-11-29T08:42:03  <kallewoof> Does gitian require you to run inside a VM or is it possible to run it directly? I keep having issues with lxc. ("lxc-execute: start.c: lxc_spawn: 1094 Failed to find gateway addresses. / Failed to spawn container "gitian".")
177 2017-11-29T08:42:44  <jonasschnelli> kallewoof: I run it directly host -> LXC
178 2017-11-29T08:42:48  <wumpus> you don't need to run gitian in a VM but it will always spawn one level of VM at least
179 2017-11-29T08:43:48  <kallewoof> OK, great! At least I'm not trying to do the impossible.
180 2017-11-29T08:45:04  <wumpus> re: eMMC speed the problem is that this doesn't really tell how it will perform under our typical leveldb load, which is seek-heavy, not linear-write/read heavy

184 2017-11-29T08:45:40  <kallewoof> (gitian-build.sh)
185 2017-11-29T08:46:03  <kallewoof> Running "bash bitcoin/contrib/gitian-build.sh" works fine so no biggie, just annoying.
186 2017-11-29T08:46:14  <wumpus> dunno, feel free to add it, shellscripting always suffers from the many different kinds of shells with slightly different syntax
187 2017-11-29T08:46:39  <kallewoof> OK
188 2017-11-29T08:49:49  <wumpus> if you use any kind of looping or conditionals please contribute a python script instead, not a shell script, it's always at least 5 iterations of bash-this-syntax-back-to-the-eighties. But anyhow we have this one and it, more or less, works.

196 2017-11-29T09:06:15  <gmaxwell> I hope someone does a novena like board with imx8, would be a lot more interesting than the original novena.

206 2017-11-29T09:12:20  <wumpus> but I think it will be quite popular, I had some link to some other planned board as well but can't find it right now
207 2017-11-29T09:12:27  <gmaxwell> wumpus: the fact that its a53 is nice... for a long time I wondered if they'd ever existed.
208 2017-11-29T09:12:40  <wumpus> midnightmagic: which one? i.mx6 is fully upstream supported, as one of the few ARM SoCs?
209 2017-11-29T09:12:57  <gmaxwell> oh nevermind I'm confused. a57 is the out of order one.
210 2017-11-29T09:13:28  <gmaxwell> and imx8 is a72 which is a newer out of order one.
211 2017-11-29T09:17:06  <wumpus> midnightmagic: that's the cubox-i variant, I've been running stock debian on mine for years. Their first board was based on Marvell Armada 510, not sure that made it upstream.

214 2017-11-29T09:21:27  <wumpus> i.MX8 seems to be 4xA53, 2xA72, for the top range model

242 2017-11-29T09:48:54  <aserc> hi need assistance - was sent some transaction few days ago from  old wallet and transaction is not  visible on explorer. Some cborg here told me to upgrade to new node and now have new node and all blockchain was rescaned or not know what was node doing. That transaction is not visible again now what is best option in node to get back that coins. could click abandon transaction but will coins than be in wallet again?
243 2017-11-29T09:50:20  <wumpus> yes, you try abandoning the transaction and re-spending the coins. Likely it was sent with too little fee.
244 2017-11-29T09:50:32  <wumpus> but ask in #bitcoin please this is not a help channel
245 2017-11-29T09:50:38  <aserc> not cborg but cberg

286 2017-11-29T11:28:32  <fanquake> wumpus If the changes look ok to you, then I think that's fine. The one thing I was going to look at was adding --disable-curve-keygen to our build options. But that doesn't really matter if you'd just like to merge it now.

288 2017-11-29T11:30:08  <wumpus> we don't use curve-keygen so disabling it mgiht speed up the build by a little bit

343 2017-11-29T14:33:08  <larafale> you are right, now that the tx got included in a block I get a valid height. But how would you explain the height: 2147483647 when it was not included? if it's not included in a block yet what does height represent and how did that number got there?
344 2017-11-29T14:34:24  <promag> larafale: that value is 31 bits

401 2017-11-29T17:20:51  <erichCompSci> Hello, I was wondering about the following problem.  Miners in bitcoin verify transactions in the blockchain by hashing the previous blocks header, transaction data and a nonce value.  However, the block is only considered a legitimate block
402 2017-11-29T17:21:03  <erichCompSci> if the final hash
403 2017-11-29T17:21:09  <erichCompSci> is below a certain threshold
404 2017-11-29T17:21:23  <erichCompSci> So...when that hash becomes as low as it can go
405 2017-11-29T17:21:37  <erichCompSci> how do new transactions get verified?
406 2017-11-29T17:21:45  <erichCompSci> ?
407 2017-11-29T17:24:11  <Murch> That question is better suited for Bitcoin.stackexchange.com than for this channel. However, the difficulty scales on a range of 2^256, so that scenario is pretty far-fetched.
408 2017-11-29T17:28:39  <erichCompSci> Well, I'll move over there then, but I'm afraid I don't understand.  At some point, it will become nearly impossible to create new blocks, hence miners will be unable to mine new bitcoins...so then how are transactions verified?  After all, miners mine by creating the blocks in the blockchain that also verify transactions...so if miners will eventually be unable to mine new coins they must be unable to create new bloc
409 2017-11-29T17:28:44  <erichCompSci> I'm asking on the developer forum
410 2017-11-29T17:29:15  <erichCompSci> someone must be thinking of this...how are you going to do the hashing post mining era so that transactions still only take 10 min
411 2017-11-29T17:29:30  <erichCompSci> new blocks in the chain only take 10 min
412 2017-11-29T17:29:32  <erichCompSci> sorry
413 2017-11-29T17:29:41  <erichCompSci> otherwise you have to revisit other things like

415 2017-11-29T17:30:43  <erichCompSci> block chain lengths can no longer be used for consensus as the hashes don't have a specific value they have to be under...what will the new rule be?
416 2017-11-29T17:30:44  <Murch> erichCompSci: The sun will go out before our capacity to increase the difficulty runs out. Also, we could just make the difficulty field bigger.
417 2017-11-29T17:31:25  <erichCompSci> But then there won't be a fixed amount of bitcoins?
418 2017-11-29T17:31:35  <erichCompSci> if you increase the difficulty field?
419 2017-11-29T17:31:52  <Murch> erichCompSci: The difficulty is not related to the reward schedule
420 2017-11-29T17:32:11  <erichCompSci> Okay, thats something I didn't know...I'll look into that thanks

445 2017-11-29T18:20:04  <Provoostenator> One issue might be that they seem to require a real organization, with legacy world stuff like someone being able to legally represent it. So sounds like this would have to go through some random related foundation.
446 2017-11-29T18:21:43  <Varunram>  Provoostenator: I think organisation means anything, like even a Github organisation
447 2017-11-29T18:22:07  <Varunram> Because every year, there are baby orgs that get a chance at SoC
448 2017-11-29T18:23:00  <Varunram> If we do discuss about this tomorrow, I can pitch in more info if you'd like :)
449 2017-11-29T18:23:50  <Provoostenator> The terms and conditions are pretty specific about legal representation though.
450 2017-11-29T18:26:14  <Varunram> Most probably, that's only in place to accept stuff, I'll ask around and come back though

565 2017-11-29T23:23:13  <jimpo> I'm looking into building the tx index in it's own thread instead of ConnectBlock. Do you think 1) it's a bad idea altogether 2) it's safe to keep the txindex data in the blocktree database or 3) the txindex should be rebuilt in its own DB?

567 2017-11-29T23:24:09  <sipa> i think the txindex should be modified to use the signal mechanism the wallet uses too
568 2017-11-29T23:24:30  <jimpo> in case 2, multiple threads would most likely access the same CBlockTreeDB, though alternately there could be multiple wrapper objects with a shared pointer to the same underlying leveldb::DB
569 2017-11-29T23:24:35  <sipa> which afaik matt is moving to support multiple threads
570 2017-11-29T23:24:56  <sipa> and yes, a separate db sounds right to me - we'd have lower consistency guarantees then, though

573 2017-11-29T23:25:51  <jonasschnelli> Anyone up for a quick review: https://github.com/bitcoin/bitcoin/pull/11616/files?
574 2017-11-29T23:26:03  <jimpo> consistency for RPC calls? couldn't it just block until the txindex is in sync?
575 2017-11-29T23:26:21  <jimpo> GetRawTransaction RPC, specifically
576 2017-11-29T23:26:35  <sipa> jimpo: perhaps
577 2017-11-29T23:27:00  <bitcoin-git> [bitcoin] aaron-hanson opened pull request #11792: Trivial: fix comments for ZeroMQ bitcoind args (master...trivial-zeromq-arguments-comments) https://github.com/bitcoin/bitcoin/pull/11792
578 2017-11-29T23:27:07  <sipa> ideally i'd say there is a separate 'indexing subsystem' which is something you talk to explicitly (perhaps using a separate endpoint like the wallet)
579 2017-11-29T23:27:37  <sipa> in that case you can easily guarantee consisntency within the subsystem (e.g. you could ask what its best block is, and that would be in sync with its indexing results)
580 2017-11-29T23:28:02  <sipa> making the rpc block until it's caught up is probably the right approach initially but feels much less clean
581 2017-11-29T23:28:37  <jimpo> That might make sense for possible future indexes, but would break compatibility for GetRawTransaction, no?

587 2017-11-29T23:33:49  <jimpo> As far as the separate DB instead of a separate key prefix within the same DB (the current design), it would require a migration, which could be avoided if we were comfortable with concurrent access to CBlockTreeDB.
