148 2017-12-06T08:35:20  <GAit> jonasschnelli: isnt the jetson just some arm board with some reasonably powerful gpu for opencl/cuda? most use cases ive seen involved opencv
149 2017-12-06T08:38:30  <jonasschnelli> GAit: it's just a SOC. You either need the dev kit or your custom ext.
150 2017-12-06T08:38:48  <jonasschnelli> GAit: The GPU power would go pretty much unused for a full node.
151 2017-12-06T08:39:20  <jonasschnelli> GAit: but the CPU, SATA feature and memory would make it a good choice for a full node in a bbox
152 2017-12-06T08:40:23  <jonasschnelli> But a custom board with LAN, I2C for a little b/w screen, SATA/SSD, etc. would something that would have to been built

157 2017-12-06T08:52:36  <GAit> non that many boards out there with sata and decent amounts of ram unfortunately

209 2017-12-06T11:20:05  <promag> wumpus: yes, there are a couple of early returns taht
210 2017-12-06T11:20:27  <promag> that happen when there is an interrupt
211 2017-12-06T11:20:38  <promag> or something fails

213 2017-12-06T11:21:57  <wumpus> promag: strange, maybe the !.. is inherited from the time when that was not the case, otherwise it makes kind of little sense. Though I'm surprised that it causes a crash.
214 2017-12-06T11:22:17  <promag> actually fRequestShutdown is checked multiple times while the block index is loaded
215 2017-12-06T11:22:41  <wumpus> ideally returning false, even at the end of the init process, should not cause a crash. But if this works around it, fine.\
216 2017-12-06T11:22:50  <wumpus> yes it should be
217 2017-12-06T11:22:56  <meshcollider> self-reminder i think we should discuss the config file situation at the meeting tomorrow, re https://github.com/bitcoin/bitcoin/pull/11829#issuecomment-349610380
218 2017-12-06T11:22:57  <promag> crash aside, i think at that point it should return true
219 2017-12-06T11:23:06  <wumpus> it should check that flag at any time that the process is interruptible
220 2017-12-06T11:23:15  <wumpus> meshcollider: yep
221 2017-12-06T11:23:54  <promag> wumpus: right, at that point it's not interruptible

224 2017-12-06T11:33:31  <wumpus> GAit: jonasschnelli: indeed, it seems any reasonably modern ARM board, even with a USB stick or SD card for storage, can keep up with the chain once it's synchronized. Additional i/o and CPU speed will contribute to the initial sync, and when catching up after it's been off.
225 2017-12-06T11:37:01  <wumpus> (as well as towards serving blocks to others if you want that)
226 2017-12-06T11:40:45  <Sentineo> yeah I am running a full node on an odroid for 7 months now
227 2017-12-06T11:41:05  <Sentineo> and mainly the assembler optimisation helps a lot
228 2017-12-06T11:46:03  <wumpus> we should probably consider making the assembly optimization be the default on ARM

231 2017-12-06T11:56:44  <CubicEarth> sat/byte seems to have become the default way people talk about fees. What about we changing the fee selector / estimator in core to display fees in those same terms?

240 2017-12-06T12:12:06  <CubicEarth> from the 'recommended' selector, yes, factor of 100.
241 2017-12-06T12:12:51  <CubicEarth> For the custom part, there is no 'satoshi' option, and there is no 'byte' option
242 2017-12-06T12:13:27  <wumpus> were it to be redesigned from scratch I'd agree with you. I think changing it now is too dangerous.
243 2017-12-06T12:14:27  <wumpus> for the RPC interface people already have software that uses the current convention, for the GUI people already have the habit of entering /kb numbers, it's kind of a fight upstream to change it
244 2017-12-06T12:14:29  <CubicEarth> because of confusion from the change?

254 2017-12-06T12:25:16  <CubicEarth> It's the double conversion that makes it 'harder'
255 2017-12-06T12:26:18  <wumpus> that's ok with me

265 2017-12-06T12:35:05  <wumpus> I don't personally think at least that adding the information in another unit and mentioning that unit will cause confusion. The danger is mostly when entering fees (e.g. the custom fee).

274 2017-12-06T12:56:10  <wumpus> the only thing I can think of is either a corruption that happens to have excised that record (maybe in the bloom filter portion of the leveldb file?), or that it somehow was missed while writing to disk
275 2017-12-06T12:57:15  <CubicEarth> Did they sync directly from one machine to the other?

297 2017-12-06T13:07:06  <wumpus> but it builds a leveldb python module that can be used to inspect bitcoind's files without making it incompatible, as most system leveldbs would do

301 2017-12-06T13:12:16  <Sentineo> ah even better, I am trying to understand how the db is set up, I would like to extract the fees only somehow. Right now I have an app that shows fees in real time and it kills my odroid. So I will have to create a separate db just to get the fees, as it creates too much stress on the system to RPC all inputs and compute the fee.

381 2017-12-06T15:55:10  <instagibbs> might be
382 2017-12-06T15:55:24  <instagibbs> I'm seeing issues too
383 2017-12-06T15:55:33  <Provoostenator> Maybe a transaction not getting fully commited to a db?
384 2017-12-06T15:55:36  <instagibbs> it's entering mempool but not being applied to balance, randomly
385 2017-12-06T15:55:40  <Provoostenator> Or some flushing thing.
386 2017-12-06T15:55:40  <instagibbs> I don't think so
387 2017-12-06T15:55:56  <instagibbs> my guess is the p2sh stuff is tripping up ISMINE logic somewhere
388 2017-12-06T15:56:51  <instagibbs> confirming it makes it stick, which means it's some mempool/unconfirmed interaction
389 2017-12-06T15:56:54  <Provoostenator> IsMine is done at the wallet level right? So are you able to produce these issues with just RPC?
390 2017-12-06T15:56:59  <instagibbs> yep
391 2017-12-06T15:57:16  <Provoostenator> Ok, that narrows is down a lot
392 2017-12-06T15:57:47  <instagibbs> ok, I just sent confirmed coins from p2sh to p2sh, stopped, restarted, it's gone
393 2017-12-06T15:57:57  <instagibbs> easy to reproduce here
394 2017-12-06T15:58:10  <instagibbs> 2017-12-06 15:57:30 Imported mempool transactions from disk: 1 succeeded, 0 failed, 0 expired, 0 already there
395 2017-12-06T15:58:17  <instagibbs> so it hits mempool, yet wallet is barfing
396 2017-12-06T15:58:30  <Provoostenator> "gone" means the bug is gone?
397 2017-12-06T15:58:42  <instagibbs> no, funds are gone from unconfirmed or confirmed
398 2017-12-06T15:58:54  <instagibbs> i believe they should be considered confirmed, since they're from yourself
399 2017-12-06T16:00:11  <Provoostenator> I think so too. I'm recompiling master now, but when I tried that a few days ago on master, sending to self is not shown as pending. Total balance is just reduced by fees. Presumably because the wallet is allowed to spend unconfirmed change.
400 2017-12-06T16:00:33  <Provoostenator> However even on master, restarting changes what's displayed. I can't remember how though, will try again in a bit.
401 2017-12-06T16:01:35  <Provoostenator> I there any way to boost compilation speed by spinning up a few EC2 nodes?

403 2017-12-06T16:03:25  <Provoostenator> Back in  my iOs days, this type of buggy behavior usually was a result of using the database on the wrong thread.
404 2017-12-06T16:03:31  <bitcoin-git> [bitcoin] MarcoFalke opened pull request #11838: qa: Add getrawtransaction in_active_chain=False test (master...Mf1712-qaRpcRawTx) https://github.com/bitcoin/bitcoin/pull/11838
405 2017-12-06T16:04:05  <Provoostenator> But obviously it could be something completely different here.
406 2017-12-06T16:07:00  <instagibbs> ugh, getbalance api. what a trainwreck

482 2017-12-06T19:00:54  <jamesob> yep, reindex

487 2017-12-06T19:02:32  <sipa> during early reindex it's around 300MB on top of dbcache for me on 0.15.1

490 2017-12-06T19:04:41  <hkjn0> just curious, do we currently have graphs somewhere of memory consumption / other resource usage over time for nodes built at different commits on master?
491 2017-12-06T19:04:49  <hkjn0> even if it took many hours to gather the data and only could be done rarely (say once per day) it might limit the range of commits where a leak could sneak in..

619 2017-12-06T21:30:15  <aj> jnewbery: i guess the right approach for dropping LEEWAY is for me to go through all the outstanding PRs and comment on the ones that add tests to fix the name, and drop LEEWAY once the second PR goes in and there aren't any pending PRs that haven't adopted the newnaming scheme. should be easy to semi-automate
