22016-06-09T00:13:05 <dgenr8> adiabat: bloom filter digests would be great, but won't kill off connection bloom filters. people want to see unconfirmed activity
32016-06-09T00:16:39 <gmaxwell> dgenr8: the addition of filtering the current transactions was a 12th hour addition to BIP37, and for many users saving an average of 13kbit/sec for a total loss of privacy is not all that interesting just to see unconfirmed transactions that their wallets can't even tell are at all remotely possily correct.
42016-06-09T00:23:27 <dgenr8> gmaxwell: so you think wallet should be watching all live tx, or none, or "either of those, just not filtered"?
52016-06-09T00:24:40 <gmaxwell> Or filtered, it's the wallets call. The exact behavior depends on the specific use case, and I think the specific use case for filtered is fairly narrow.
62016-06-09T00:25:09 <gmaxwell> If the digests idea had come up at the time of BIP37, I think it would have been implemented and filtering of relayed transactions wouldn't have been.

1082016-06-09T07:04:47 <gmaxwell> Hm. I think with the 0.13 sorted inv behavior can actually wipe out the orphan map when we have no outstanding unresponded getdata for transactions from any peers. (this wouldn't be a good idea with the pre 0.13 behavior in the network, so we probably shouldn't do that now)

1152016-06-09T07:28:55 <jonasschnelli> We need a decentralized github web. :)
1162016-06-09T07:29:21 <sipa> You mean git?
1172016-06-09T07:29:26 <jonasschnelli> hehe...
1182016-06-09T07:29:48 <jonasschnelli> Yes. With the option of creating issues, public announcements of pull requests, etc.
1192016-06-09T07:47:55 <wumpus> there have been ideas to create a git.bitcoincore.org which mirrors the repository and where one can clone from if the github repository is offline, the thing is, no one really has time to set up and babysit such things
1202016-06-09T07:49:24 <warren> Does the git repo use signed merge commits?
1212016-06-09T07:49:55 <btcdrak> wumpus: maintenance is a bitch.
1222016-06-09T07:50:04 <sipa> warren: we always gpg sign merge commits
1232016-06-09T07:50:05 <btcdrak> warren: yes.
1242016-06-09T07:50:16 <sipa> warren: and there is a script to verify that
1252016-06-09T07:52:29 <jonasschnelli> wumpus: you mean mirroring the github data?
1262016-06-09T07:52:42 <jonasschnelli> Or just the git?
1272016-06-09T07:52:51 <wumpus> just the git
1282016-06-09T07:53:01 <jonasschnelli> Okay. That would be trivial.
1292016-06-09T07:53:12 <wumpus> we do mirror the github data in a github repository, could also push that there
1302016-06-09T07:53:16 <jonasschnelli> btcdrak: where is bitcoincore.org hosted?
1312016-06-09T07:53:17 <btcdrak> I'm sure the odd Github Unicorn doesnt cause us _that_ much trouble.

1352016-06-09T07:53:40 <jonasschnelli> Yes. But we can't work on a decentralized system on a centralized github. :)
1362016-06-09T07:53:43 <btcdrak> but can set a DNS entry to any server...
1372016-06-09T07:53:50 <btcdrak> (a subdomain I mean)
1382016-06-09T07:54:28 <btcdrak> jonasschnelli: decentralisation is a myth in this case.
1392016-06-09T07:54:42 <wumpus> we've been signing merge commits consistently from ~2013 or so, and were one of the first projects to do this
1402016-06-09T07:55:03 <sipa> unfortunately git commit ids are only sha1 :(
1412016-06-09T07:55:55 <wumpus> well it's not perfect security but certainly puts of a barrier, which is the point of any security feature
1422016-06-09T07:55:58 <btcdrak> i love how this entire conversation comes up almost verbatim again every now and again :)
1432016-06-09T07:56:23 <wumpus> we're like broken records
1442016-06-09T07:56:33 <btcdrak> mayeb I should write a FAQ :-p
1452016-06-09T07:58:42 <btcdrak> but seriously, my point is: someone sees a Unicorn, and rather than press F5, it ignites a sledge hammer to crack peanut response :-D
1462016-06-09T07:58:55 <wumpus> please include a "database corrupted" entry
1472016-06-09T07:59:09 <wumpus> really doesn't help that everyone creates a new issue every time they get that
1482016-06-09T07:59:34 <wumpus> where 99 out of 100 times it's simply a hardware problem
1492016-06-09T08:00:04 <btcdrak> agreed, I think there are a bunch of common issue we could cover.
1502016-06-09T08:00:07 <wumpus> we really should discourage people from creating new issues about that, unless there's new information to report
1512016-06-09T08:00:24 <wumpus> maybe they could post to an existing issue for statistics or something
1522016-06-09T08:01:46 <gmaxwell> change the message to "Apparent hardware error" :)
1532016-06-09T08:02:47 <wumpus> gcc has the same thing, where people keep reporting SEGV crashes caused by overclocked or otherwise flakey CPUs, while compiling run-of-the-mill software
1542016-06-09T08:03:41 <wumpus> gmaxwell: yes, that would be a good idea
1552016-06-09T08:04:18 <paveljanik> maybe even a link to the FAQ entry about this?
1562016-06-09T08:06:17 <sipa> nobody believes you when you tell them their hardware is broken
1572016-06-09T08:06:27 <gmaxwell> a few do.
1582016-06-09T08:06:29 <wumpus> still, it helps to have it written down somewhere
1592016-06-09T08:06:35 <wumpus> in a clear way
1602016-06-09T08:06:44 <wumpus> instead of repeating it all the time, increasingly annoyed :)
1612016-06-09T08:06:46 <gmaxwell> I actually think they believe it from the sofware more than names on IRC.
1622016-06-09T08:07:11 <gmaxwell> well whats worse is that they search the log entry, and find other people explaining that it's totally not hardware and the software is buggy and what not'
1632016-06-09T08:07:19 <gmaxwell> and they show up "hey you morons still haven't fixed this!"
1642016-06-09T08:07:44 <gmaxwell> they also run -rescan ten times and it won't go away and why should they have to run it an eleventh!?
1652016-06-09T08:08:19 <gmaxwell> Is there a german word for where you both feel apologetic towards someone and want to strangle them?
1662016-06-09T08:10:36 <wumpus> the thing is, even if there are software bugs involved, opening more issues about it isn't going to help a thing
1672016-06-09T08:11:20 <gmaxwell> A lot of people just don't have a good mental model of how this whole thing works. Like, if it's still buggy and reported, then why haven't we fixed it? obviously we don't care or are lazy.
1682016-06-09T08:11:22 <wumpus> I think I'm going to create one 'data corruption' issue and close the others as duplicates
1692016-06-09T08:11:50 <gmaxwell> Same reason why reports seldom have the information required to reproduce the issue.
1702016-06-09T08:12:27 <wumpus> well most issues are fairly good in that regard
1712016-06-09T08:12:28 <gmaxwell> if we had simply forgotten, reporting again would help-- and we do, from time to time, forget actual issues.
1722016-06-09T08:12:42 <wumpus> generally not issues that are reported on github
1732016-06-09T08:12:49 <gmaxwell> Right.
1742016-06-09T08:12:52 <wumpus> sure, if something is said on IRC or the mailing list it gets lost
1752016-06-09T08:12:56 <gmaxwell> at least not while they're still open.
1762016-06-09T08:12:59 <wumpus> the point of an issue tracker is to have a persistent URL for an issue
1772016-06-09T08:13:30 <gmaxwell> But clearly we've fogotten the data corruption because it keeps hapenning. :P QED.
1782016-06-09T08:13:33 <wumpus> if it gets too crowded it loses its value
1792016-06-09T08:14:01 <wumpus> then it's just like mentioning it once on reddit, no one will ever look back to it
1802016-06-09T08:14:10 <wumpus> heh
1812016-06-09T08:14:28 <wumpus> well every time I had actual data corruption I investigated in depth
1822016-06-09T08:16:52 <jonasschnelli> What about providing a script/cli-tool (C++) that would perform some heave leveldb tests with block like data? Something like a bitcoin-hardware-test?
1832016-06-09T08:17:07 <gmaxwell> it's called bitcoind.
1842016-06-09T08:17:19 <wumpus> it will take long to detect errors, so no one will run that
1852016-06-09T08:17:25 <wumpus> heh exactly
1862016-06-09T08:17:28 <gmaxwell> it's not just leveldb though, the cpu load from signature validation triggers memory errors on some systems.
1872016-06-09T08:17:30 <jonasschnelli> Okay.. :)
1882016-06-09T08:17:59 <gmaxwell> when we have wumpus' snapshot stuff perhaps we could also do other things to retry/recover in the face of error.
1892016-06-09T08:18:33 <wumpus> there are just so many types of hardware problems that can result in corruptions
1902016-06-09T08:18:39 <gmaxwell> I have mixed feelings, users really shouldn't count on faulty computers... esp for handling irreversable money...
1912016-06-09T08:19:05 <wumpus> and there is software to detect hardware problems, that's a completely orthogonal thing :)
1922016-06-09T08:19:29 <jonasschnelli> Right. Agree.
1932016-06-09T08:19:32 <gmaxwell> many are resolved just by being able to go back to earlier state... obviously flying writes that corrupt data at rest.. well not much then can be done there... (well, we do have forward error correction code...)
1942016-06-09T08:20:19 <jonasschnelli> I just had serval crashes on my Pine64 (due to false configuration and maybe USB issues). I always had to reindex/IBD from the scratch.
1952016-06-09T08:20:33 <jonasschnelli> Wumpuses snapshot idea would be a live-safer for such situations

2592016-06-09T13:27:48 <instagibbs> is there a list of known issues with getbalance? I'm getting inconsistencies, and the comments in the code give me instructions which causes a json parsing error(??)
2602016-06-09T13:27:52 <instagibbs> "// getbalance and "getbalance * 1 true" should return the same number"
2612016-06-09T13:28:16 <instagibbs> oh the latter is probably me being dumb, but I still am getting weird balances

2652016-06-09T13:36:00 <sipa> are you typing "getbalance * 1 true" on the command line? that will expand * to the list of files in your current directory
2662016-06-09T13:36:22 <instagibbs> i was, but i escaped it yes

2682016-06-09T13:37:01 <instagibbs> If I send funds to myself in regtest, it immediately shows up in getbalance, but not getbalance * 1 true
2692016-06-09T13:37:01 <sipa> then how do you get a parsing error?
2702016-06-09T13:37:17 <instagibbs> no that was my 2nd issue, now fixed
2712016-06-09T13:37:23 <sipa> ah, getbalance will show unconfirmed sends from yourself
2722016-06-09T13:37:35 <instagibbs> well... I will change that comment then

3162016-06-09T15:20:39 <dgenr8> instagibbs: getbalance and getbalance "" appear to differ in their treatment of 0-conf utxos from self. getbalance "" 1 seems to always includes them. getbalance "*" follows from getbalance "" (since "" is just a specific account)
3172016-06-09T15:21:42 <dgenr8> instagibbs: also sendfrom "A" seems to not work in a test I just just (it selected a utxo not belonging to "A")
3182016-06-09T15:21:48 <dgenr8> justdid
3192016-06-09T15:22:03 <instagibbs> yeah i opened an issue
3202016-06-09T15:22:12 <instagibbs> since im not sure what the comment should be changed to
3212016-06-09T15:22:25 <instagibbs> there are nooks and crannies depending on settings you are running
3222016-06-09T15:25:50 <dgenr8> agreed that since -spendzeroconfchange affects the result of getbalance, the comment is too general. prolly just remove it
3232016-06-09T15:26:08 <sipa> dgenr8: sendfrom just subtracts the balance from A; it always uses all utxos
3242016-06-09T15:26:25 <sipa> dgenr8: as accounts don't own utxos in any way
3252016-06-09T15:26:41 <instagibbs> dgenr8, yes I think removal is best

3662016-06-09T18:20:44 <wumpus> gmaxwell: sure, an external log handler would just wait for the line to complete
3672016-06-09T18:21:19 <gmaxwell> K. I've never considered that case before and thought it potentially useful to raise the question.
3682016-06-09T18:21:20 <wumpus> there's no rule that log messages need to be written within a certain time
3692016-06-09T18:21:57 <gmaxwell> well generally we should write them a line at a time or otherwise we'll get log entries split by threads.
3702016-06-09T18:22:43 <wumpus> yes, that came up during review too, it can be done here because there is nothing else running at that time
3712016-06-09T18:22:50 <wumpus> and this is less spammy than printing a line for every N%
3722016-06-09T18:23:14 <gmaxwell> Right. I agree that it can be done here.

3792016-06-09T18:36:21 <BakSAj> not sure if we make it to 95% in this diff period
3802016-06-09T18:36:46 <gmaxwell> mostly depends on KNC going offline again or not.
3812016-06-09T18:37:12 <adam3us> they maybe selling the equipment

4042016-06-09T19:01:52 <MarcoFalke> any topic suggestions today?
4052016-06-09T19:02:23 <gmaxwell> We can talk some about ongoing compact block testings, I have a few things to report.
4062016-06-09T19:02:42 <wumpus> last meeting there was talk of release lifecycles documentation, btcdrak and David Harding have been working on that page here: https://github.com/bitcoin-core/bitcoincore.org/pull/179 https://github.com/btcdrak/bitcoincore.org/pull/2 this needs review
4072016-06-09T19:02:53 <cfields_> wumpus: I have 2 p2p refactor PRs that i'd _very_ much like to have in 0.13. I'm not sure how you're considering those in terms of freezing
4082016-06-09T19:02:54 <gmaxwell> instagibbs: nickler: NicolasDorier: CodeShark:
4092016-06-09T19:03:14 <CodeShark> yo
4102016-06-09T19:03:23 <MarcoFalke> cfields_: I think p2p refactor can go in after the feature freeze?
4112016-06-09T19:03:29 <gmaxwell> We apparently can no longer compile on hosts with only 2GB ram with defaults.
4122016-06-09T19:03:39 <wumpus> other TODOs from last week: review and merge #8126 (std::shared_ptr based CTransaction storage in mempool) - that was done, #7935 (Versionbits: GBT support) - also done
4132016-06-09T19:03:46 <MarcoFalke> I mean it is not a new feature ;)
4142016-06-09T19:04:04 <gmaxwell> well it was more like 1.5GB ram before.

4192016-06-09T19:04:46 <gmaxwell> We have docs that say 1.5GB, they're gonna be like the blocksize on bitcoin.org :)

4212016-06-09T19:04:55 <wumpus> depends on what else is running on the machine
4222016-06-09T19:05:34 <gmaxwell> I've been going through #7598/#7600.
4232016-06-09T19:05:38 <wumpus> #topic compile-time memory usage
4242016-06-09T19:05:45 <wumpus> what can *concretely* be done here?
4252016-06-09T19:05:58 <jonasschnelli> would kick out boost help?
4262016-06-09T19:05:59 <luke-jr> -O0
4272016-06-09T19:06:01 <wumpus> is it something worrying?
4282016-06-09T19:06:08 <cfields_> has anyone measured to see if there are particular objects that are especially guilty?
4292016-06-09T19:06:11 <CodeShark> what's eating up all the RAM?
4302016-06-09T19:06:14 <wumpus> yes, we have cfields_
4312016-06-09T19:06:20 <cfields_> ie. main.cpp/net.cpp ?
4322016-06-09T19:06:21 <luke-jr> CodeShark: ld/GCC doesn't free memory

4462016-06-09T19:07:52 <wumpus> lots of people have posted about it, but there doesn't seem to be a clear solution
4472016-06-09T19:08:00 <jonasschnelli> main.cpp -> 1248524bytes ... ^^
4482016-06-09T19:08:33 *** moli has joined #bitcoin-core-dev
4492016-06-09T19:08:37 <wumpus> reducing the number of included headers works, I think
4502016-06-09T19:08:41 <sipa> present
4512016-06-09T19:08:46 <cfields_> I have PRs which break up net.h/netbase.h, i'd be curious to see if those make a significant difference
4522016-06-09T19:09:00 <gmaxwell> in any case, something to be aware of and nudge a bit at... some refactorings to move code around would help.
4532016-06-09T19:09:13 <wumpus> also building with clang helps
4542016-06-09T19:09:21 <wumpus> it uses a lot less memory at the same compile settings, usually
4552016-06-09T19:09:25 <gmaxwell> and be independantly good for reasons unrelated to peak memory usage.
4562016-06-09T19:10:05 <cfields_> i'd assume that mem usage correlates solidly with compile time
4572016-06-09T19:10:41 *** molz has quit IRC
4582016-06-09T19:10:55 <CodeShark> not so sure - lots of small files might mean the bottleneck is disk access
4592016-06-09T19:11:29 <sipa> CodeShark: come on
4602016-06-09T19:11:32 <CodeShark> in any case, it would be good to bring down the peak mem usage
4612016-06-09T19:11:32 <wumpus> the bottleneck in compilation is hardly ever disk access, at least *reading* disk access
4622016-06-09T19:11:37 <sipa> reading in 100 files?
4632016-06-09T19:11:43 <sipa> sequentially
4642016-06-09T19:12:08 <BakSAj> would be cool, if btc full nodes could continue to be runnable on Rasberry Pi ... with 1GB RAM
4652016-06-09T19:12:37 <jeremyrubin> BakSAj: runnable is not compileable on?
4662016-06-09T19:12:40 <gmaxwell> not sure there is much else to say here. I only brought it up for general awareness issues, since I think it's likely a death by 1000 cuts that can be improved in a multitude of ways.
4672016-06-09T19:12:54 <wumpus> seek/read access for source files is only a problem for really huge projects, and then especially when the source is hosted on some horrible network file system (like clearcase), in any case bitcoin doesn't even come close
4682016-06-09T19:13:03 <cfields_> heh, disk is negligible. It's easy to see where time is spent with -ftime-report.
4692016-06-09T19:13:17 <wumpus> but like always: measure before you start talking about bottlenecks
4702016-06-09T19:13:35 <jonasschnelli> I think adding cross compile depends options for ARM and AARCH64 would also reduce the "memory problem" (at least the amount of complains): https://github.com/bitcoin/bitcoin/issues/8162
4712016-06-09T19:13:58 <BakSAj> jeremyrubin: preferably both compileable and operatable
4722016-06-09T19:13:59 <wumpus> BakSAj: for small embedded systems you should use cross-compilation
4732016-06-09T19:14:03 <cfields_> jonasschnelli: i'm halfway through the changes needed there.
4742016-06-09T19:14:13 <jeremyrubin> i have had machines take a bit of time on autogen.sh fyi
4752016-06-09T19:14:18 <jonasschnelli> cfields_: nice. Focus on Qt5.6 first. :)
4762016-06-09T19:14:31 *** hsmiths2 has quit IRC
4772016-06-09T19:14:34 <wumpus> you can cross compile on ARM using depends, we just don't distribute ARM binaries
4782016-06-09T19:14:37 <cfields_> jonasschnelli: actually, arm/aarch64 already work fine with depends. Just have to use NO_QT=1 manually.

4802016-06-09T19:14:41 *** Chris_Stewart_5 has quit IRC
4812016-06-09T19:14:42 <gmaxwell> I'm skeptical that the intersection of rpi users that complain about compile issues and people who will cross compile is the emptyset. But cross compiling is good.
4822016-06-09T19:14:44 <wumpus> cfields_: yes, it works fine
4832016-06-09T19:14:51 <luke-jr> for comparison, webkit-based stuff typically uses up to 12 GB RAM with debug symbols, and much much less without..
4842016-06-09T19:14:56 <gmaxwell> er isn't the empty set, you get what I mean.
4852016-06-09T19:15:01 *** hsmiths has joined #bitcoin-core-dev
4862016-06-09T19:15:07 <cfields_> luke-jr: oh, good point...
4872016-06-09T19:15:13 <wumpus> it's *very easy* tocross compile for ARM
4882016-06-09T19:15:14 <jonasschnelli> I think NO_QT=1 for ARM/AARCH64 could be a start (even for "official binaries").
4892016-06-09T19:15:20 <wumpus> with the depends system
4902016-06-09T19:15:24 <wumpus> jonasschnelli: yes
4912016-06-09T19:15:28 <cfields_> the gitian-debug PR turns on debug symbols, so gitian mem requirement is bumped after that.
4922016-06-09T19:15:37 <gmaxwell> wumpus: a lot of people using rpi2 like systems do not have another linux host.
4932016-06-09T19:15:42 <luke-jr> wumpus: that builds static binaries, which is wasteful on RAM
4942016-06-09T19:15:44 <jonasschnelli> Also ARM is used more and more for GUI systems.
4952016-06-09T19:15:50 <jeremyrubin> can autogen.sh be made faster?
4962016-06-09T19:16:01 <wumpus> jeremyrubin: no
4972016-06-09T19:16:15 <wumpus> not by us, at least
4982016-06-09T19:16:15 <BakSAj> ok, thanks for explaining.. personally i had no trouble compiling 0.12.1 on rpi 3, was afraid that minimum requirements will raise with future releases
4992016-06-09T19:16:32 <jonasschnelli> luke-jr: if you want to run bitcoind on a RiP (or similar) static builds are fine. Mostly you don't have tons of other tools that could share libraries installed.
5002016-06-09T19:16:32 <BakSAj> since suprisingly many nodes run on rpi
5012016-06-09T19:16:44 <jeremyrubin> wumpus: maybe the one thing that is fixed by a faster disk
5022016-06-09T19:16:50 <luke-jr> jonasschnelli: I'm thinking more of Bitcoin-Qt
5032016-06-09T19:16:59 <cfields_> jonasschnelli: as qt's gui plugin situation improves, we may be able to move back to the shared-qt builds
5042016-06-09T19:17:05 <wumpus> I'm sure minimum requirements will raise with future releases, that's just the way things are, we'll try to raise them not too much though
5052016-06-09T19:17:11 <MarcoFalke> jonasschnelli: I think we already have notes on how to corss compile to arm?
5062016-06-09T19:17:13 <jonasschnelli> Agree. Static linking qt is not ideal. But lets don't roll this up again.

5082016-06-09T19:17:23 <btcdrak> oh meeting
5092016-06-09T19:17:35 <jonasschnelli> MarcoFalke: notes, yes. But it should be included in our release builds (gitian)
5102016-06-09T19:17:42 <MarcoFalke> jup, agree
5112016-06-09T19:17:46 <cfields_> jonasschnelli: sorry, i meant that directly in the context of shipping arm+gui binaries
5122016-06-09T19:17:56 <luke-jr> jonasschnelli: for now, people just compile natively to avoid static, so suggesting cross-compile isn't a real option
5132016-06-09T19:18:06 <wumpus> jeremyrubin: I'm not sure. I have no idea what autogen.sh would be spending time on. But it seems more a GNU problem thatn a bitcoin core problem :)
5142016-06-09T19:18:09 * gmaxwell looks forward to arm (+gui) binaries in the sometime future.
5152016-06-09T19:18:23 <wumpus> jeremyrubin: I'm surprised it's autogen.sh taking a lot of time not configure, which has this huge list of scripts to execute for probing
5162016-06-09T19:18:48 * luke-jr fully intends to use an ARM system with Core(Knots) as his hot wallet in some months.
5172016-06-09T19:18:50 <cfields_> jeremyrubin: you can use a quicker shell for autogen. IIRC dash vs. bash shaves a few seconds off
5182016-06-09T19:19:15 <wumpus> well arm non-GUI binaries would already be a great step forward, one step at a tme
5192016-06-09T19:19:15 <luke-jr> autogen.sh isn't even part of building; it's a developer tool
5202016-06-09T19:19:17 <cfields_> wumpus: ah, as a feature-freeze request: ok to plan on arm bins (without gui) for 0.13 ?
5212016-06-09T19:19:27 <luke-jr> if you're running autogen.sh, that means you're running from git, and you shouldn't do that
5222016-06-09T19:19:30 <cfields_> i can try to have that done today
5232016-06-09T19:19:30 <jonasschnelli> cfields_: ack, +1
5242016-06-09T19:19:33 <wumpus> I think arm gui would be prett much a per-distro afair
5252016-06-09T19:19:36 <wumpus> cfields_: sure!

5272016-06-09T19:19:39 <jeremyrubin> luke-jr: are we making build faster for developers or for users?

5302016-06-09T19:19:47 <cfields_> ok
5312016-06-09T19:20:06 <luke-jr> jeremyrubin: I think the concern is "ability to build" rather than "speed to build"
5322016-06-09T19:20:11 <gmaxwell> jeremyrubin: users shouldn't need to run autogen-- if they get the source tarballs we have, it should already be autogenned.
5332016-06-09T19:20:26 <cfields_> ^^
5342016-06-09T19:20:36 <BakSAj> cool, rpi fans will love you :-)
5352016-06-09T19:20:44 <wumpus> but the people actually doing a lot of builds are developers, only they would care about a few more/less seconds in the build scripting

5402016-06-09T19:21:18 <wumpus> BakSAj: people are doing that actually, that's one of the motivations for the ARM binaries
5412016-06-09T19:21:28 <BakSAj> lol ok
5422016-06-09T19:21:28 <luke-jr> next step is therefore to support SPV mode when bandwidth is expensive ;)
5432016-06-09T19:21:30 <gmaxwell> BakSAj: abcore, it works fine.
5442016-06-09T19:21:39 <jonasschnelli> luke-jr: +1
5452016-06-09T19:21:41 <luke-jr> but that's post-0.13 IMO
5462016-06-09T19:21:45 <wumpus> absolutely
5472016-06-09T19:22:22 <wumpus> in any case it's too late to start on anything new for 0.13, for that we have to consider which of the current pulls can go in
5482016-06-09T19:22:47 <luke-jr> can we get in [8-bit] key generation type?
5492016-06-09T19:23:32 <jonasschnelli> 32bit!
5502016-06-09T19:23:41 <jonasschnelli> You can provide a migration patch for Knots
5512016-06-09T19:23:52 <jonasschnelli> Isn't that trivial?
5522016-06-09T19:23:53 <BakSAj> will 0.13 contain just segwit code or actual softfork also? tnx
5532016-06-09T19:24:03 <jonasschnelli> SW SF can be 0.13.1
5542016-06-09T19:24:17 <jonasschnelli> SW are mostly not coupled with major releases
5552016-06-09T19:24:21 <jeremyrubin> I think that 0.13.1 will be worse for upgrade times
5562016-06-09T19:24:24 <wumpus> SW should be released in a minor release
5572016-06-09T19:24:26 <jeremyrubin> does anyone have data on that
5582016-06-09T19:24:29 <gmaxwell> BakSAj: major releases do not contain network consensus changes.
5592016-06-09T19:24:31 <sdaftuar> do we think segwit is going in to 0.13?
5602016-06-09T19:24:42 <sdaftuar> (without activation scheduled)
5612016-06-09T19:24:52 <jeremyrubin> wumpus: isn't it a major change?
5622016-06-09T19:24:52 <petertodd> sdaftuar: you mean, 0.13.0, or 0.13.x>0?
5632016-06-09T19:24:53 <luke-jr> jonasschnelli: migration is not very practical if 32-bit uses the same version number in Core as 8-bit in Knots already is
5642016-06-09T19:24:57 <sdaftuar> 0.13.0
5652016-06-09T19:24:59 <btcdrak> sdaftuar: yes, sipa wanted to merge it soon to master
5662016-06-09T19:25:01 <CodeShark> what happened to doing it in 0.12.x?
5672016-06-09T19:25:02 <luke-jr> jonasschnelli: maybe this needs more off-meeting discussion then
5682016-06-09T19:25:08 <btcdrak> (without mainnet defs)
5692016-06-09T19:25:08 <jonasschnelli> luke-jr: agree
5702016-06-09T19:25:15 <sdaftuar> seems like there are still open issues, and no ACKs
5712016-06-09T19:25:16 <wumpus> jeremyrubin: well from what I've heard minor releases are usually more popular, especialy .1, as some people don't trust .0 :)
5722016-06-09T19:25:26 <gmaxwell> CodeShark: nothing, there are confused questions.
5732016-06-09T19:25:27 <sdaftuar> so i don't see how it's going to be merged in the next week
5742016-06-09T19:25:48 <btcdrak> sdaftuar: why?
5752016-06-09T19:25:48 <luke-jr> jeremyrubin: segwit is a major change to Bitcoin - not Bitcoin Core.
5762016-06-09T19:25:51 * jonasschnelli thinks sipa is allowed to merge without ACK
5772016-06-09T19:25:52 <gmaxwell> jeremyrubin: we have a long thought out published spec on this, please don't divert the meeting to debating it. I can direct you to the information after the meeting.

5792016-06-09T19:26:07 <jeremyrubin> wumpus: interesting... I do tend to not upgrade any of my software major versions for 6 months. diversion over
5802016-06-09T19:26:27 <sipa> well merging segwit without fork enabled is not in contradiction with "not doing a consensus change in a major release"
5812016-06-09T19:26:36 <jonasschnelli> agree
5822016-06-09T19:26:41 <CodeShark> right
5832016-06-09T19:26:47 <wumpus> sure
5842016-06-09T19:26:49 <luke-jr> no objections to merging segwit code without activation
5852016-06-09T19:26:50 <jonasschnelli> Also, getting ACK for SW is extremly hard. Nobody wants to take the risk.
5862016-06-09T19:26:51 <gmaxwell> sure, there are code motion logistics that favor merging it.
5872016-06-09T19:26:51 <sdaftuar> to be clear i'm not talking about any kind of release policy, just code-readiness / review
5882016-06-09T19:26:54 <btcdrak> jeremyrubin: see out lifecycle docs https://github.com/bitcoin-core/bitcoincore.org/pull/179

5912016-06-09T19:27:57 <wumpus> so is SW ready for merge (into master/0.13)?
5922016-06-09T19:28:06 <sdaftuar> it has no ACKs, and some open issues to be resolved
5932016-06-09T19:28:31 <wumpus> ok
5942016-06-09T19:28:33 <jonasschnelli> major open issue? Or more nitish stuff?
5952016-06-09T19:28:35 <sdaftuar> minor
5962016-06-09T19:28:49 <wumpus> if it is not critical it can also be fixed in a later pull
5972016-06-09T19:28:51 <sdaftuar> but bugs, not style nits
5982016-06-09T19:29:09 <wumpus> oh known bugs should be addressed in the pull itself
5992016-06-09T19:29:21 <sipa> i think everything will be addressed in my next batch of patches
6002016-06-09T19:29:29 <btcdrak> sipa: great!
6012016-06-09T19:29:41 *** Chris_Stewart_5 has quit IRC
6022016-06-09T19:29:42 <gmaxwell> should people be acking the reviwew PR or the rebase/reorg?
6032016-06-09T19:29:42 <luke-jr> sipa: does that include expanding 2nd push to 75 bytes max? or is that still an open thing?
6042016-06-09T19:30:19 <sipa> luke-jr: this is the place to ask, and i would say no, there is no point
6052016-06-09T19:30:27 <sipa> but perhaps others have another opinion
6062016-06-09T19:30:32 <btcdrak> luke-jr: I didnt understand where 75 came from.
6072016-06-09T19:30:42 <sipa> btcdrak: up to 75 is easy
6082016-06-09T19:30:43 <luke-jr> btcdrak: largest size that wouldn't require additional testing
6092016-06-09T19:31:18 <gmaxwell> has to do with the opcode types changing for different sizes of push.
6102016-06-09T19:31:47 <sipa> so, opinions?
6112016-06-09T19:31:51 <btcdrak> 32->40->75 seems like a big jump
6122016-06-09T19:32:06 <gmaxwell> btcdrak: from the code perspective they're all the same.
6132016-06-09T19:32:19 <luke-jr> my opinion is there is no point limiting it (beyond the impl/test cost of >75), and such limits could very well prevent future softforks
6142016-06-09T19:32:49 <luke-jr> more tolerant enables softforks, so should be preferred over useless limits
6152016-06-09T19:33:08 <gmaxwell> Luke-jr's argument has merit in my opinion-- it can be reduced later, but I don't have a strongly held view. I'm not aware of a DOS attack risk created by not having the stricter limit earlier.
6162016-06-09T19:33:44 <gmaxwell> (of course, IsStandardness should be strictly limited)
6172016-06-09T19:33:44 <luke-jr> to expand the limit later requires a hardfork
6182016-06-09T19:34:00 <luke-jr> yes, node policy should reject any unknown witnesses period
6192016-06-09T19:34:23 <CodeShark> ok, I think luke-jr has a strong argument
6202016-06-09T19:34:27 <btcdrak> that makes sense
6212016-06-09T19:34:47 <sipa> there should be no need for more than 256-bit hash + some versioning metadata
6222016-06-09T19:35:14 <sipa> and setting it to more gives it the impression that there is
6232016-06-09T19:35:16 <petertodd> sipa: or, to be precise if there is that means Bitcoin is more broken than that
6242016-06-09T19:35:24 <sipa> petertodd: exactly
6252016-06-09T19:35:33 <jeremyrubin> luke-jr: in general I agree with keeping flexible, but do you have an example for sipa of why you'd want it?
6262016-06-09T19:35:36 <gmaxwell> The biggest harm I see is that allowing a larger size here does limit the ability to make utxo entries limited in size in the future, potentially. But it could be done later. It also enabled policy bypass to abuse the utxo set for data storage, though it's not much of an issue there.
6272016-06-09T19:35:42 <luke-jr> sipa: it doesn't need to give that impression. I don't think we need to predict the future too much here.
6282016-06-09T19:36:12 *** kxie has joined #bitcoin-core-dev
6292016-06-09T19:36:23 <gmaxwell> luke-jr: for example, if you were to argue that we might someday need 512 bit hashes, I'd agree-- but then I'd point out that in that case there would need to be a hardfork to change all the other things.
6302016-06-09T19:36:26 <sipa> i'd rather not rely on isstandardness when reasoning about longer term future
6312016-06-09T19:37:01 <petertodd> in a MR implementation I did, it turned out to be very advantageous if the things in the MMR were fixed side forperformance
6322016-06-09T19:37:13 <luke-jr> jeremyrubin: any case where we would need indicators in the UTXO set itself; but I don't have a concrete example at this time
6332016-06-09T19:37:19 <gmaxwell> Also, not allowing it in SW doesn't preclude it in the future, you'd just need to use a different version type signaling in that case.
6342016-06-09T19:37:35 <luke-jr> for example, we could have added the maturity stuff in the 2nd push if we didn't have nSequence
6352016-06-09T19:37:43 <gmaxwell> Yes, I really wish UTXO entries were fixed size.
6362016-06-09T19:37:53 <sdaftuar> sipa: isn't there a strong deterrent against abuse, because your funds are anyone-can-spend to older nodes?

6382016-06-09T19:37:59 <luke-jr> gmaxwell: you'd need a new commitment entirely
6392016-06-09T19:38:13 <luke-jr> gmaxwell: in addition to the current one
6402016-06-09T19:38:24 <sipa> sdaftuar: there is no rule preventing 0-value outputs
6412016-06-09T19:38:34 <_anthony_> just use the private key of a payment address to store the 256 bits
6422016-06-09T19:38:37 <sdaftuar> ah, good point
6432016-06-09T19:38:41 <sipa> (if you ignore relay polify)
6442016-06-09T19:39:09 <luke-jr> abuse is already possible. this doesn't make it worse. if in the future we make it better, we can limit this at the same time
6452016-06-09T19:39:28 <gmaxwell> if one assumes a fixed size utxo entry, luke's suggestion basically doubles the utxo set size.
6462016-06-09T19:39:32 <petertodd> sipa: though, for that specific case I find it ahrd to think of a abuse use-case that'd care about that, given you could screw up the usse-case by spending those outputs
6472016-06-09T19:39:51 <luke-jr> gmaxwell: we can't assume that today, and if we softfork an assumption tomorrow, we can limit this then also
6482016-06-09T19:40:44 <gmaxwell> We've probably spent more time discussing it now than the decision is worth.
6492016-06-09T19:41:14 <wumpus> ok, next topic?
6502016-06-09T19:41:24 <wumpus> #topic compact block testing
6512016-06-09T19:41:27 <luke-jr> so we use 75 for now, and discuss reducing it later?
6522016-06-09T19:41:33 <gmaxwell> (and that time could be better spent reviewing/testing more corner cases... lets continue discussion elsewhere I guess)
6532016-06-09T19:42:34 <btcdrak> so compact blocks...
6542016-06-09T19:42:41 <gmaxwell> OK. So there are some number of nodes running compactblocks on the public network.. I have 12 peers at the moment, matt has another half dozen in the new relay network that I'm not connected to.
6552016-06-09T19:42:52 <gmaxwell> Things seem to be working well there, instagibbs has posted some charts.
6562016-06-09T19:42:56 <wumpus> I've been running a compact blocks node for a few days, no crashes to report :)
6572016-06-09T19:43:16 <instagibbs> yes i love charts http://imgur.com/iq2lRGl
6582016-06-09T19:43:26 <gmaxwell> I've been conducting some new tests with a network of nodes with a modified version of compact blocks that reduces the hash size to 16 bits in order to test corner cases around collisions.
6592016-06-09T19:43:27 <instagibbs> blue stuff is in kB fwiw
6602016-06-09T19:43:30 <wumpus> lots of succesfully reconstructed blocks
6612016-06-09T19:43:31 <luke-jr> (ugh, Travis is apparently "detecting abuse" on the Bitcoin code itself, so every clone will be affected?)
6622016-06-09T19:43:36 <btcdrak> Two large mining pools have also been running them, connected to their pool nodes for block source, one is behind the GFW
6632016-06-09T19:43:40 <instagibbs> blue dot == 0 fetched txns
6642016-06-09T19:44:20 <gmaxwell> I found a few bugs, which matt has fixed but not pushed to the PR yet. Bugs were things like if the cmptblk message was rubbish, it would wait for the peer to timeout before requesting the block normally.
6652016-06-09T19:44:48 <instagibbs> I intended to review the PR then got ill. Still planning to review.
6662016-06-09T19:44:57 <gmaxwell> I think this particular testing technique of modifying the code to make rare cases common is pretty effective and will result in good testing of most of those corner cases.
6672016-06-09T19:45:05 <wumpus> luke-jr: (offtopic) that started happening with the parallel testing I think
6682016-06-09T19:45:08 <sipa> gmaxwell: agree

6802016-06-09T19:47:07 <wumpus> #link https://github.com/bitcoin/bitcoin/pull/8068
6812016-06-09T19:47:15 <cfields_> has there been discussion of a servicebit for compact blocks? Now that we have the dns seed prefixes, that would allow for very quick discovery
6822016-06-09T19:47:23 <gmaxwell> Based on the issues I found, probably the interaction with block fetching logic needs more review.
6832016-06-09T19:47:37 <btcdrak> cfields_: if it deploys in 0.13 it wont be necessary
6842016-06-09T19:47:43 <gmaxwell> cfields_: IMO I don't see a need to preferrentially peer. I expect support to become sufficiently ubiquitious fast enough.

6872016-06-09T19:48:10 <gmaxwell> it's not something that anyone has a reason to not support, except for just not having implemented it.
6882016-06-09T19:48:13 <btcdrak> hrm, action point is to forget :)
6892016-06-09T19:48:16 <sipa> cfields_: the argument brought up before was tgat service bits should be used for critical
6902016-06-09T19:48:28 <sipa> for critically required services
6912016-06-09T19:48:41 <gmaxwell> like your node won't work right if you don't have peers with the right services.
6922016-06-09T19:48:46 <wumpus> btcdrak: yeah for people testing the code to use the other branch
6932016-06-09T19:48:49 <luke-jr> makes sense
6942016-06-09T19:48:55 <sipa> and the only time when yoi critically need a compact block peer is as a miner, who should be curating their connections anyway
6952016-06-09T19:48:59 <jeremyrubin> in #8086 where is the salt generated btw?
6962016-06-09T19:49:09 <cfields_> hmm, fair enough
6972016-06-09T19:49:35 <wumpus> and miners can look at the protocol version to see if their peer supports compact blocks?
6982016-06-09T19:49:48 <gmaxwell> jeremyrubin:
6992016-06-09T19:49:49 <gmaxwell> +CBlockHeaderAndShortTxIDs::CBlockHeaderAndShortTxIDs(const CBlock& block) :
7002016-06-09T19:49:52 <gmaxwell> + nonce(GetRand(std::numeric_limits<uint64_t>::max())),
7012016-06-09T19:50:12 <luke-jr> wumpus: I don't think we can assume a specific protocol version supports it
7022016-06-09T19:50:27 <luke-jr> if we have a future version with better compact blocks, we may want to drop support for the current one
7032016-06-09T19:50:28 <jeremyrubin> thanks
7042016-06-09T19:50:29 <Lightsword> I think using service bits is a good idea, mainually curtailing connections is very time consuming and raisies the barrier to entry for mining
7052016-06-09T19:50:32 <gmaxwell> wumpus: you can do the handshake.
7062016-06-09T19:50:36 <sipa> wumpus: no, miners should connect to a known peer that supports it
7072016-06-09T19:50:41 <luke-jr> Lightsword: neither are likely to be necessary
7082016-06-09T19:51:09 <wumpus> gmaxwell: right
7092016-06-09T19:51:22 <gmaxwell> Please, service bits are basically forever and we only have 32 of them, I expect the window between some and nearly all use of this to only be a few months to a year long.
7102016-06-09T19:51:24 <sipa> wumpus: because just supporting compact blocks is not enough, they also need to have good uptime and reliability latency, bandwodth, ...
7112016-06-09T19:51:29 <sipa> gmaxwell: we have 64
7122016-06-09T19:51:41 <gmaxwell> Same difference. (really? hmph!)
7132016-06-09T19:51:46 <jeremyrubin> I would suggest either writing the entropy to a file once or having it settable in a config file
7142016-06-09T19:51:48 <wumpus> we should have a concept of temporary service bits, like for the versionbits
7152016-06-09T19:52:05 <sipa> jeremyrubin: that's a good idea but orthogonal
7162016-06-09T19:52:11 <luke-jr> as long as nobody relies on service bits, they can be temporary
7172016-06-09T19:52:16 <btcdrak> we dont need preferential peering for compact blocks. It wont take long for wide network support.
7182016-06-09T19:52:17 <luke-jr> ie, use them as hints
7192016-06-09T19:52:23 <cfields_> don't we have a range designated for playground?
7202016-06-09T19:52:27 <luke-jr> yes
7212016-06-09T19:52:31 <jeremyrubin> sipa: (yes, sorry, just reviewing it now)
7222016-06-09T19:52:34 <Lightsword> a service bit to indicate a secondary service bit field needs to be used?
7232016-06-09T19:52:47 <luke-jr> one of which is currently getting full-RBF temporary usage
7242016-06-09T19:52:50 <wumpus> Lightsword: that would completely make it unuseful for preferential peering
7252016-06-09T19:52:50 <gmaxwell> jeremyrubin: uh. I'm not sure what you're talking about there... the nonces are per block and should not be predictable.
7262016-06-09T19:53:12 <wumpus> Lightsword: (as neither addr messages nor the DNS seeds would be aware of the secondary mechanism)
7272016-06-09T19:53:14 <gmaxwell> statically configuring it would be broken.
7282016-06-09T19:53:29 <wumpus> why would you want to fix the entropy statically?
7292016-06-09T19:53:33 <instagibbs> gmaxwell, perhaps setting cmpctblock as a tie-breaker for keeping connection?
7302016-06-09T19:53:41 <gmaxwell> Okay, in any case, I think thats all I've got there.
7312016-06-09T19:53:50 <btcdrak> ding ding, we have 7 mins remaining
7322016-06-09T19:53:52 <instagibbs> well, I guess "he sent me blocks fast" is/will be one, same thing
7332016-06-09T19:53:54 <cfields_> static entropy is much easier to test :p
7342016-06-09T19:53:54 <gmaxwell> instagibbs: sounds like a fine additional ranker in the connection management stuff.
7352016-06-09T19:54:05 <wumpus> instagibbs: +1
7362016-06-09T19:54:06 <sipa> indeed
7372016-06-09T19:54:13 <jeremyrubin> cfields_: yep
7382016-06-09T19:54:16 <gmaxwell> instagibbs: though yea, the 'most recent blocks' probably mostly covers it.
7392016-06-09T19:54:35 <BakSAj> which version are compact blocks planned for?
7402016-06-09T19:54:40 <sipa> related to that: please review gmaxwell's patch for adding fast blkck and tx relayers for not evicted
7412016-06-09T19:54:41 <jeremyrubin> gmaxwell: it doesn't harm security so long as it's kept secret from peers
7422016-06-09T19:54:50 <btcdrak> BakSAj: 0.13.0
7432016-06-09T19:54:51 <instagibbs> sipa, which number
7442016-06-09T19:54:59 <sipa> instagibbs: sec
7452016-06-09T19:55:04 <jeremyrubin> gmaxwell: nvm -- forgot you have to send it?
7462016-06-09T19:55:07 <gmaxwell> jeremyrubin: the nonce used for compact blocks must be sent to peers or they can't recover the block.
7472016-06-09T19:55:12 <petertodd> wumpus: we do have temporary service bits
7482016-06-09T19:55:19 <BakSAj> btcdrak: thanks!
7492016-06-09T19:55:33 <sdaftuar> gmaxwell: thoughts on #7598/#7600? you said above that you'd started review
7502016-06-09T19:55:40 <Lightsword> isnât it likely weâre going to overhaul the p2p protocol by the time we run out of service bits?
7512016-06-09T19:55:45 <sdaftuar> i still think it should be a priority to get those PRs merged for 0.13.0...
7522016-06-09T19:55:47 <instagibbs> I don't think connecting to cmpctblock peers will be hard unless we get sybil'd by AWS forks
7532016-06-09T19:55:57 <gmaxwell> sdaftuar: I like them and will ACK soon, once I come up with a useful way to test.
7542016-06-09T19:56:08 <sipa> sdaftuar: me too, i started revieweing but got caught up on other things
7552016-06-09T19:56:09 <gmaxwell> sdaftuar: I agree.
7562016-06-09T19:56:24 <sipa> Lightsword: maybe
7572016-06-09T19:56:41 <sipa> Lightsword: it's often hard to predict how long protocols live
7582016-06-09T19:56:47 <gmaxwell> I think important big PRs I'd really like to have in 0.13 are SW, Compact blocks, CFPF related, and BIP32.
7592016-06-09T19:56:51 <sdaftuar> gmaxwell: ok, let me know if you want help with the sim environment i shared with you, i think that makes it easy
7602016-06-09T19:56:54 <instagibbs> sipa, https://github.com/bitcoin/bitcoin/pull/8084
7612016-06-09T19:56:59 <gmaxwell> There are a bunch of small things (including all of mine)
7622016-06-09T19:57:16 <sipa> instagibbs: that one, thanks
7632016-06-09T19:57:45 <cfields_> off-topic: quickly, before I forget. I'll be headed out of town on Friday and only reachable for emergencies for ~10 days. If anyone needs anything from me before I go, speak up now :)
7642016-06-09T19:57:58 <sipa> cfields_: for how long?
7652016-06-09T19:58:03 <sipa> a month?
7662016-06-09T19:58:04 *** supasonic has joined #bitcoin-core-dev
7672016-06-09T19:58:04 <Lightsword> maybe we should just have a service bit for flagging fast relay nodes/miners in general for preferential peering rather than making it flag compact blocks specifically
7682016-06-09T19:58:17 <wumpus> only features have to be in before the feature freeze, anything that can be interpreted as bug fixes or anti-DoS measures doesn't have the deadline of next week
7692016-06-09T19:58:20 <wumpus> also SW is special
7702016-06-09T19:58:30 <sipa> Lightsword: we should also have an evil bit that abusive nodes should set
7712016-06-09T19:58:45 <gmaxwell> Lightsword: "the I am a DOS attack master node, please connect to me" flag?
7722016-06-09T19:58:48 <Chris_St1> brilliant
7732016-06-09T19:58:51 <btcdrak> sipa: ^.^
7742016-06-09T19:58:56 <wumpus> as we discussed above it's a consensus change so it can't be enabled in a major release first
7752016-06-09T19:59:04 <cfields_> sipa: for ~10 days. I'll be gone for a month total, but working for the last few weeks.
7762016-06-09T19:59:10 <sipa> i see
7772016-06-09T19:59:23 <wumpus> he announced that well in advance
7782016-06-09T19:59:30 <gmaxwell> lynch him!
7792016-06-09T19:59:33 <luke-jr> cfields_: review of https://github.com/bitcoin/bitcoin/pull/5872 ? :D
7802016-06-09T19:59:36 <gmaxwell> oh in advance, okay.
7812016-06-09T19:59:38 <gmaxwell> :P
7822016-06-09T19:59:47 <BakSAj> :-)

7852016-06-09T20:00:03 <instagibbs> wumpus, all-but-SF SW would be nice

7912016-06-09T20:00:18 <luke-jr> FWIW, I will also be travelling June 20th-early July (but probably semi-available and working)
7922016-06-09T20:00:24 <sipa> thanks all, this was an interesting meeting
7932016-06-09T20:00:29 <cfields_> along the same lines, review plea for #8128
7942016-06-09T20:00:57 <wumpus> instagibbs: I know, just wanted the situation around SW to be clear for people reading the logs
7952016-06-09T20:01:04 *** cryptapus has quit IRC
7962016-06-09T20:01:05 <instagibbs> +1
7972016-06-09T20:01:35 <BakSAj> btw, is there a rough estimate when 0.13.1 may come?
7982016-06-09T20:01:47 <BakSAj> or version with segwit sf
7992016-06-09T20:01:48 <instagibbs> Probably when a certain Softfork is ready....
8002016-06-09T20:01:49 <gmaxwell> yea, my comments were assuming that it would be released in 0.12.x first, but parallel included in master.
8012016-06-09T20:01:53 <luke-jr> BakSAj: "when it's ready"
8022016-06-09T20:01:55 <btcdrak> BakSAj: SW will be released in 0.12.x
8032016-06-09T20:01:57 <gmaxwell> BakSAj: 0.12.x
8042016-06-09T20:02:05 <cfields_> luke-jr: btw, i believe I found your issue wrt out-of-tree build and chowning
8052016-06-09T20:02:23 <gmaxwell> BakSAj: development operats long ahead of public release, we're often working up to a year ahead of whats released.
8062016-06-09T20:02:32 <cfields_> luke-jr: we rely on "git diff" to update the index, but it can't if .git is read-only.
8072016-06-09T20:02:48 <luke-jr> aha
8082016-06-09T20:02:52 <BakSAj> uf little confused
8092016-06-09T20:03:06 <BakSAj> now you release 0.13.0 with segwit code
8102016-06-09T20:03:11 <gmaxwell> the interest in merging SW in master mostly comes from the fact that it isn't merged is holding people back from some changes because they don't want to make the SW rebases more complex.
8112016-06-09T20:03:14 <btcdrak> gmaxwell: BlueMatt just pushed the fixes to #8068 compact blocks
8122016-06-09T20:03:18 <BakSAj> but then 0.12.2 with code and activation comes
8132016-06-09T20:03:22 <instagibbs> BakSAj, ok, so 0.13 isn't out. That means if SW is released, it goes into 0.12.2
8142016-06-09T20:03:29 <instagibbs> then will still show up in 0.13
8152016-06-09T20:03:56 <gmaxwell> For example, I wrote a patch to remove three loops over all transactions in accetblock... then shelved it, because its just a tiny speedup, and would conflict with the SW patches.
8162016-06-09T20:04:07 <BakSAj> wont this bring confusion whether to run 0.12.2 or 0.13 ?
8172016-06-09T20:04:17 *** molz has joined #bitcoin-core-dev
8182016-06-09T20:04:37 <instagibbs> btcdrak, sigh, my block hit rate is going to poop :(
8192016-06-09T20:04:38 <cfields_> luke-jr: could you verify that your process works if you add a "chown -R user:user" after the "chown -R root:root ." ?
8202016-06-09T20:04:47 <sipa> BakSAj: what os are you running?
8212016-06-09T20:04:51 <luke-jr> BakSAj: there is no one version everyone must run
8222016-06-09T20:05:01 <gmaxwell> instagibbs: start up the relay node client for a bit to prefill your mempool.
8232016-06-09T20:05:07 <BakSAj> sipa ?
8242016-06-09T20:05:08 <luke-jr> cfields_: eh, that sounds like a noop?
8252016-06-09T20:05:15 <instagibbs> gmaxwell, hmm ok pretty sure I have that installed
8262016-06-09T20:05:18 <btcdrak> instagibbs: well you could spin up a new node instead...
8272016-06-09T20:05:19 <sipa> BakSAj: what version of your os are you running.
8282016-06-09T20:05:24 <cfields_> luke-jr: er, sorry...
8292016-06-09T20:05:34 <cfields_> luke-jr: "chown -R user:user .git"
8302016-06-09T20:05:40 <BakSAj> sipa: for full node?
8312016-06-09T20:05:52 <btcdrak> instagibbs: rsync your chainstate etc.
8322016-06-09T20:05:55 <sipa> BakSAj: whatever, i'm trying to make an analogu
8332016-06-09T20:06:04 *** moli has quit IRC
8342016-06-09T20:06:07 <BakSAj> lol, win10
8352016-06-09T20:06:10 <sipa> BakSAj: you run 0.12.x to get more stable/tested code
8362016-06-09T20:06:24 <sipa> BakSAj: you run 0.13.0 to get the latest and greates
8372016-06-09T20:06:39 <sipa> and segwit is independent of that
8382016-06-09T20:06:50 <sipa> it will be released in a point update to both
8392016-06-09T20:07:09 <gmaxwell> SW is not a client feature, it's part of the network protocol.
8402016-06-09T20:07:21 <BakSAj> i understand how sw livecycle usually works, but im confused about thing that 0.13.0 wont have SF active
8412016-06-09T20:07:43 <luke-jr> BakSAj: if 0.13.0 is released before SW, it won't have SW; if it is released after SW, it won't remove SW
8422016-06-09T20:07:59 <gmaxwell> BakSAj: it may or may not, but it won't be the first release with it. 0.12.x (likely 0.12.2) will.
8432016-06-09T20:07:59 <luke-jr> SW introduction is independent from Core's release cycle
8442016-06-09T20:08:03 <sipa> BakSAj: because in order to enable SW, we need many code changes
8452016-06-09T20:08:29 <sipa> BakSAj: it's a pita to keep maintaining those in parallel when we know the code worms
8462016-06-09T20:08:32 <sipa> *works
8472016-06-09T20:08:46 <BakSAj> ah
8482016-06-09T20:08:51 <luke-jr> BakSAj: if 0.12.1 and 0.13.0 are released before SW, then SW will be added in 0.13.1 and 0.12.2; if only 0.12.1 is released before SW, then it will be added to 0.12.2, and the later 0.13.0 will also have it still
8492016-06-09T20:09:01 <BakSAj> i had bad assumption about 0.13.0
8502016-06-09T20:09:07 <BakSAj> guys, thanks for explanation
8512016-06-09T20:09:19 <gmaxwell> btcdrak: in the future, please wait for travis to finish before nagging people to update. :)

8732016-06-09T20:50:03 <dgenr8> sipa: on .11.0 and .12.0 (I didn't try newer), after sendfrom "A", no subtraction from A is reflected in listaccounts or getbalance "A"
8742016-06-09T20:50:24 <dgenr8> sipa: it looks like there is no way query ledger entries like this (or those created by move) :/
8752016-06-09T20:51:30 <dgenr8> sipa: listunspent shows account A as an attribute of a utxo with address created by getnewaddress A. sendfrom A should probably wipe that out ... but that strays into trying to fix it
8762016-06-09T20:52:23 <sipa> dgenr8: receive accounts are a property of incoming payments, not utxos
8772016-06-09T20:52:50 <sipa> dgenr8: the fact that a send is not reflected in getbalance is a bug
8782016-06-09T20:53:18 <dgenr8> I guess was speaking loosely ... i mean it has a txid and a vout, and it is unspent :)
