1482017-12-06T08:35:20  <GAit> jonasschnelli: isnt the jetson just some arm board with some reasonably powerful gpu for opencl/cuda? most use cases ive seen involved opencv
1492017-12-06T08:38:30  <jonasschnelli> GAit: it's just a SOC. You either need the dev kit or your custom ext.
1502017-12-06T08:38:48  <jonasschnelli> GAit: The GPU power would go pretty much unused for a full node.
1512017-12-06T08:39:20  <jonasschnelli> GAit: but the CPU, SATA feature and memory would make it a good choice for a full node in a bbox
1522017-12-06T08:40:23  <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

1572017-12-06T08:52:36  <GAit> non that many boards out there with sata and decent amounts of ram unfortunately

2132017-12-06T11:21:57  <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.
2142017-12-06T11:22:17  <promag> actually fRequestShutdown is checked multiple times while the block index is loaded
2152017-12-06T11:22:41  <wumpus> ideally returning false, even at the end of the init process, should not cause a crash. But if this works around it, fine.\
2162017-12-06T11:22:50  <wumpus> yes it should be
2172017-12-06T11:22:56  <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
2182017-12-06T11:22:57  <promag> crash aside, i think at that point it should return true
2192017-12-06T11:23:06  <wumpus> it should check that flag at any time that the process is interruptible
2202017-12-06T11:23:15  <wumpus> meshcollider: yep
2212017-12-06T11:23:54  <promag> wumpus: right, at that point it's not interruptible
2222017-12-06T11:24:07  <wumpus> promag: agree

2242017-12-06T11:33:31  <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.
2252017-12-06T11:37:01  <wumpus> (as well as towards serving blocks to others if you want that)
2262017-12-06T11:40:45  <Sentineo> yeah I am running a full node on an odroid for 7 months now
2272017-12-06T11:41:05  <Sentineo> and mainly the assembler optimisation helps a lot
2282017-12-06T11:46:03  <wumpus> we should probably consider making the assembly optimization be the default on ARM

2312017-12-06T11:56:44  <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?

2402017-12-06T12:12:06  <CubicEarth> from the 'recommended' selector, yes, factor of 100.
2412017-12-06T12:12:51  <CubicEarth> For the custom part, there is no 'satoshi' option, and there is no 'byte' option
2422017-12-06T12:13:27  <wumpus> were it to be redesigned from scratch I'd agree with you. I think changing it now is too dangerous.
2432017-12-06T12:14:27  <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
2442017-12-06T12:14:29  <CubicEarth> because of confusion from the change?

2542017-12-06T12:25:16  <CubicEarth> It's the double conversion that makes it 'harder'

2652017-12-06T12:35:05  <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).

2972017-12-06T13:07:06  <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

3012017-12-06T13:12:16  <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.

3892017-12-06T15:56:54  <Provoostenator> IsMine is done at the wallet level right? So are you able to produce these issues with just RPC?
3902017-12-06T15:56:59  <instagibbs> yep
3912017-12-06T15:57:16  <Provoostenator> Ok, that narrows is down a lot
3922017-12-06T15:57:47  <instagibbs> ok, I just sent confirmed coins from p2sh to p2sh, stopped, restarted, it's gone
3932017-12-06T15:57:57  <instagibbs> easy to reproduce here
3942017-12-06T15:58:10  <instagibbs> 2017-12-06 15:57:30 Imported mempool transactions from disk: 1 succeeded, 0 failed, 0 expired, 0 already there
3952017-12-06T15:58:17  <instagibbs> so it hits mempool, yet wallet is barfing
3962017-12-06T15:58:30  <Provoostenator> "gone" means the bug is gone?
3972017-12-06T15:58:42  <instagibbs> no, funds are gone from unconfirmed or confirmed
3982017-12-06T15:58:54  <instagibbs> i believe they should be considered confirmed, since they're from yourself
3992017-12-06T16:00:11  <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.
4002017-12-06T16:00:33  <Provoostenator> However even on master, restarting changes what's displayed. I can't remember how though, will try again in a bit.
4012017-12-06T16:01:35  <Provoostenator> I there any way to boost compilation speed by spinning up a few EC2 nodes?

4032017-12-06T16:03:25  <Provoostenator> Back in  my iOs days, this type of buggy behavior usually was a result of using the database on the wrong thread.
4042017-12-06T16:03:31  <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
4052017-12-06T16:04:05  <Provoostenator> But obviously it could be something completely different here.
4062017-12-06T16:07:00  <instagibbs> ugh, getbalance api. what a trainwreck
4072017-12-06T16:08:03  <instagibbs> going to debug once it re-compiled with --enable-debug...

4862017-12-06T19:02:09  <BlueMatt> yea
4872017-12-06T19:02:32  <sipa> during early reindex it's around 300MB on top of dbcache for me on 0.15.1

4902017-12-06T19:04:41  <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?
4912017-12-06T19:04:49  <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..
