732017-05-01T07:51:47 <wumpus> gmaxwell: sipa: I'm just worried that taking up the concern of doing proper seeding in bitcoin core itself, without anyone else looking at it or using it, will result in a worse outcome for us. Allthe platform specific stuff is a hell to maintain, and it forces us to stay up to date in developments in that area
742017-05-01T07:52:27 <wumpus> a person can't be a specialist in everything, and neither can a project, I think
752017-05-01T07:53:15 *** ChanServ sets mode: -o wumpus
762017-05-01T07:54:38 <gmaxwell> someone else writing it doesn't magically make it good however, it can just be a way to launder bad code.
772017-05-01T07:54:54 <wumpus> yes, that is true too
782017-05-01T07:56:37 <gmaxwell> the openssl code smells pretty bad. (in particular, IIRC if it's unable to open any strong random device it keeps on going)-- but it does at least have the benefit of being widely used. I too am not keep on platform specfifc code, we don't want to have a case where someone runs on BeOS and doesn't get randomness at all because /dev/urandom is symlinked ot /dev/zero and how were we so stupid as t
792017-05-01T07:56:43 <gmaxwell> o not know this and account for it. :P
802017-05-01T07:56:51 <wumpus> but someone else cooporating on it outside the context of bitcoin core (which is pretty narrow) isn't necessarily bad
812017-05-01T07:58:47 <gmaxwell> The challenge we have for doing a general RNG library which you suggested before (we tried) is that our needs are pretty different and addressing it in the general case is really really hard. In particular, other applications have strong performance requirements that necessitates lockfree state management, while at the same time handling forced RNG reseeding across forks. The approaches people
822017-05-01T07:58:53 <gmaxwell> have come up with for this are ugly and pretty platform specific. And these are both properties that we don't need.
832017-05-01T07:59:10 <wumpus> yes, defending openssl in that regard is pretty pointless
842017-05-01T07:59:43 <gmaxwell> (they're handling the fork transisition stuff using things like special page flags that cause tagged pages to get zeroed on fork ... and other similar functionality that is different on every OS that implements something like it)
852017-05-01T07:59:52 <wumpus> "In particular, other applications have strong performance requirements that necessitates lockfree state management" then we explicitly exclude those
862017-05-01T08:00:08 <wumpus> the kind of thing I'm thinking of it other wallets
872017-05-01T08:00:08 <gmaxwell> ('there' in this case referring to other people attempting general RNG code.)
882017-05-01T08:00:21 <wumpus> usually need low-frequency, but very good entropy
892017-05-01T08:00:24 <gmaxwell> okay we could do something that would perhaps mostly only be used by other bitcoin things.
902017-05-01T08:00:32 <gmaxwell> (or cryptocurrency rather)
912017-05-01T08:01:08 <wumpus> yup other cryptocurrency and things that need strong keys
922017-05-01T08:01:24 <wumpus> it's a growing space at least
932017-05-01T08:01:52 <wumpus> indeed I don't care the least about satisfying any need for randomness for any project in existence
942017-05-01T08:02:26 <wumpus> but improving wallets in general would already be a nice aim
952017-05-01T08:02:32 <gmaxwell> well one thing that was suggested was just doing initial seed generation as a library, which is basically all you need for most wallet keygen things, and has the least concern.
962017-05-01T08:02:39 <wumpus> yup
972017-05-01T08:03:08 <wumpus> then we agree I guess :)
982017-05-01T08:03:55 <gmaxwell> okay, thats a fine scope.
992017-05-01T08:08:03 <wumpus> I sometimes wonder what gpg's key generation does
1002017-05-01T08:09:41 <wumpus> this is the only non-wallet example of a long term key, not easy to replace, potential disaster if compromised, that I can think of right now

1032017-05-01T08:54:34 <kallewoof> Maybe bitcoin could use libgcrypt (GnuPG uses it for keys, I think; it has a bunch of random things) instead of OpenSSL. Though it seems to be LGPL. Some parts of it are dual MPL-compat though, like random-drbg.c
1042017-05-01T08:54:52 <kallewoof> "a bunch of random things" = "a bunch of things related to RNG"
1052017-05-01T08:55:23 <kallewoof> Uh, meant MIT, not MPL

3962017-05-01T18:47:43 <sipa> yes
3972017-05-01T18:48:35 <sipa> 0.8.0 through 0.14.1 should have compatible chainstates
3982017-05-01T18:48:42 <sipa> (forward and backward)
3992017-05-01T18:52:05 *** dodomojo has quit IRC
4002017-05-01T18:58:07 <jl2012> thanks
4012017-05-01T18:58:52 <sipa> actually, op_return pruning was added in between somewhere, if you downgrade, the startup check may complain
4022017-05-01T18:58:59 <gmaxwell> uh, no.
4032017-05-01T18:59:19 <gmaxwell> chainstate obfscuation was introduced around 0.11.x
4042017-05-01T18:59:23 <sipa> oh!
4052017-05-01T18:59:36 <gmaxwell> (maybe in 0.12.0?)
4062017-05-01T19:00:00 <sipa> indeed, 0.12.0
4072017-05-01T19:00:15 *** jcliff42 has quit IRC
4082017-05-01T19:01:06 <jl2012> ok. So my case is: I have a working 0.9 node, and I want to minimize the time to IBD a 0.13 node . Should I just copy the blocks folder?
4092017-05-01T19:01:36 <sipa> copy the blocks folder and the chainstate
4102017-05-01T19:01:45 <sipa> copy the chainstate first, while the node is offline
4112017-05-01T19:02:02 <sipa> the blocks dir can be copied later (and the node can have run in between)
4122017-05-01T19:02:03 <jl2012> but I have to keep it online
4132017-05-01T19:02:10 <jl2012> so it will corrupt?
4142017-05-01T19:02:25 <luke-jr> could try lsyncd I guess

4162017-05-01T19:12:38 <SopaXorzTaker> sipa, what's this bounty? http://permalink.gmane.org/gmane.comp.bitcoin.devel/3089
4172017-05-01T19:12:42 <BlueMatt> cfields: lol, so I've now got a long branch with a bunch of scripted diffs that make CBlockIndexes outside of validation (and mostly outside of CChainState) all const :p
4182017-05-01T19:12:47 <BlueMatt> guess that stuff /is/ useful :p
4192017-05-01T19:12:49 <SopaXorzTaker> (on-topic to core dev)
4202017-05-01T19:13:17 <cfields> :)
4212017-05-01T19:14:07 <BlueMatt> also, yay, const access to validation outside of validation!
4222017-05-01T19:14:09 <sipa> SopaXorzTaker: why do you ask me?
4232017-05-01T19:14:14 <BlueMatt> crazy, yo

4262017-05-01T19:16:24 <BlueMatt> cfields: re: 10189: instead of TRAVIS_COMMIT_RANGE might it make sense to go back until the nearest merge commit?
4272017-05-01T19:17:30 <cfields> BlueMatt: why? I believe TRAVIS_COMMIT_RANGE includes the merge commit it creates
4282017-05-01T19:17:43 <BlueMatt> well i meant eg for private repo runs
4292017-05-01T19:17:51 <BlueMatt> it'd be nice, but i guess doesn't matter /that/ much
4302017-05-01T19:17:58 <BlueMatt> it just feels weird that it would only be tested on prs
4312017-05-01T19:18:21 <cfields> BlueMatt: ah, I hadn't even considered non-PRs. Yes.
4322017-05-01T19:19:00 <cfields> BlueMatt: can probably diff to branch point

4382017-05-01T19:22:06 <cfields> BlueMatt: Well, actually, it may break for simple pushes (not sure, I have those disabled). I assume TRAVIS_COMMIT_RANGE is empty for those.
4392017-05-01T19:22:12 <BlueMatt> I get "bash: !b}: event not found"
4402017-05-01T19:23:26 <SopaXorzTaker> ROLL, ROT, SWAP
4412017-05-01T19:23:27 <cfields> BlueMatt: got a branch I can look at?
4422017-05-01T19:23:37 <BlueMatt> cfields: I'm literally just running the command manually
4432017-05-01T19:23:47 <SopaXorzTaker> that's a lifetime of a TX script in a nutshell
4442017-05-01T19:23:49 <BlueMatt> https://github.com/bitcoin/bitcoin/pull/10189/files#diff-6f65a3cbb40a72a97be8d4930d214685R25
4452017-05-01T19:23:51 <BlueMatt> that line fails
4462017-05-01T19:24:39 <BlueMatt> SopaXorzTaker: thanks, but lets keep this on-topic :) people often read scrollback and its very rude when there is a bunch of chatter that is off-topic in the scrollback that people have to spend time reading later
4472017-05-01T19:26:02 <SopaXorzTaker> +
4482017-05-01T19:26:59 <cfields> BlueMatt: hmm, unsure. Does it object to the sed syntax?
4492017-05-01T19:27:20 <BlueMatt> cfields: yes, I assume its the last part of the sed line (that is the only place with a !b)
4502017-05-01T19:27:30 <BlueMatt> but its bash complaining, not sed
4512017-05-01T19:30:27 <cfields> BlueMatt: i'm not sure why it would matter in a script, but it sounds like history expansion's kicking in. Does using ' ' instead fix it?
4522017-05-01T19:31:00 <BlueMatt> using ' ' where?
4532017-05-01T19:31:05 * BlueMatt is not fluent in sed
4542017-05-01T19:31:17 <cfields> BlueMatt: sec
4552017-05-01T19:33:04 <cfields> yea, i can reproduce when running the sed script by hand. Must be some interactive/non-interactive difference
4562017-05-01T19:33:13 <BlueMatt> oh strange
4572017-05-01T19:33:38 <cfields> BlueMatt: https://pastebin.com/raw/q9N6NE4b
4582017-05-01T19:34:04 <BlueMatt> ah, heh
4592017-05-01T19:34:11 <BlueMatt> s'pose i should have tried that
4602017-05-01T19:38:05 <cfields> I'll fix that and add a quick change to make it only run on PRs
4612017-05-01T19:38:22 <BlueMatt> thanks
