 73 2017-05-01T07:51:47  <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
 74 2017-05-01T07:52:27  <wumpus> a person can't be a specialist in everything, and neither can a project, I think
 75 2017-05-01T07:53:15  *** ChanServ sets mode: -o wumpus
 76 2017-05-01T07:54:38  <gmaxwell> someone else writing it doesn't magically make it good however, it can just be a way to launder bad code.
 77 2017-05-01T07:54:54  <wumpus> yes, that is true too
 78 2017-05-01T07:56:37  <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
 79 2017-05-01T07:56:43  <gmaxwell> o not know this and account for it. :P
 80 2017-05-01T07:56:51  <wumpus> but someone else cooporating on it outside the context of bitcoin core (which is pretty narrow) isn't necessarily bad
 81 2017-05-01T07:58:47  <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
 82 2017-05-01T07:58:53  <gmaxwell>  have come up with for this are ugly and pretty platform specific.  And these are both properties that we don't need.
 83 2017-05-01T07:59:10  <wumpus> yes, defending openssl in that regard is pretty pointless
 84 2017-05-01T07:59:43  <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)
 85 2017-05-01T07:59:52  <wumpus> "In particular, other applications have strong performance requirements that necessitates lockfree state management" then we explicitly exclude those
 86 2017-05-01T08:00:08  <wumpus> the kind of thing I'm thinking of it other wallets
 87 2017-05-01T08:00:08  <gmaxwell> ('there' in this case referring to other people attempting general RNG code.)
 88 2017-05-01T08:00:21  <wumpus> usually need low-frequency, but very good entropy
 89 2017-05-01T08:00:24  <gmaxwell> okay we could do something that would perhaps mostly only be used by other bitcoin things.
 90 2017-05-01T08:00:32  <gmaxwell> (or cryptocurrency rather)
 91 2017-05-01T08:01:08  <wumpus> yup other cryptocurrency and things that need strong keys
 92 2017-05-01T08:01:24  <wumpus> it's a growing space at least
 93 2017-05-01T08:01:52  <wumpus> indeed I don't care the least about satisfying any need for randomness for any project in existence
 94 2017-05-01T08:02:26  <wumpus> but improving wallets in general would already be a nice aim
 95 2017-05-01T08:02:32  <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.
 96 2017-05-01T08:02:39  <wumpus> yup
 97 2017-05-01T08:03:08  <wumpus> then we agree I guess :)
 98 2017-05-01T08:03:55  <gmaxwell> okay, thats a fine scope.
 99 2017-05-01T08:08:03  <wumpus> I sometimes wonder what gpg's key generation does
100 2017-05-01T08:09:41  <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

103 2017-05-01T08:54:34  <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
104 2017-05-01T08:54:52  <kallewoof> "a bunch of random things" = "a bunch of things related to RNG"

397 2017-05-01T18:48:35  <sipa> 0.8.0 through 0.14.1 should have compatible chainstates
398 2017-05-01T18:48:42  <sipa> (forward and backward)

400 2017-05-01T18:58:07  <jl2012> thanks
401 2017-05-01T18:58:52  <sipa> actually, op_return pruning was added in between somewhere, if you downgrade, the startup check may complain
402 2017-05-01T18:58:59  <gmaxwell> uh, no.
403 2017-05-01T18:59:19  <gmaxwell> chainstate obfscuation was introduced around 0.11.x
404 2017-05-01T18:59:23  <sipa> oh!
405 2017-05-01T18:59:36  <gmaxwell> (maybe in 0.12.0?)
406 2017-05-01T19:00:00  <sipa> indeed, 0.12.0
407 2017-05-01T19:00:15  *** jcliff42 has quit IRC
408 2017-05-01T19:01:06  <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?
409 2017-05-01T19:01:36  <sipa> copy the blocks folder and the chainstate
410 2017-05-01T19:01:45  <sipa> copy the chainstate first, while the node is offline
411 2017-05-01T19:02:02  <sipa> the blocks dir can be copied later (and the node can have run in between)
412 2017-05-01T19:02:03  <jl2012> but I have to keep it online
413 2017-05-01T19:02:10  <jl2012> so it will corrupt?
414 2017-05-01T19:02:25  <luke-jr> could try lsyncd I guess

417 2017-05-01T19:12:42  <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
418 2017-05-01T19:12:47  <BlueMatt> guess that stuff /is/ useful :p
419 2017-05-01T19:12:49  <SopaXorzTaker> (on-topic to core dev)
420 2017-05-01T19:13:17  <cfields> :)
421 2017-05-01T19:14:07  <BlueMatt> also, yay, const access to validation outside of validation!
422 2017-05-01T19:14:09  <sipa> SopaXorzTaker: why do you ask me?
423 2017-05-01T19:14:14  <BlueMatt> crazy, yo
424 2017-05-01T19:14:21  <sipa> SopaXorzTaker: ask the person who sent that mail
425 2017-05-01T19:14:30  <bitcoin-git> [bitcoin] jnewbery opened pull request #10307: [tests] allow zmq test to be run in out-of-tree builds (master...fix_zmq_test_out_of_tree) https://github.com/bitcoin/bitcoin/pull/10307
426 2017-05-01T19:16:24  <BlueMatt> cfields: re: 10189: instead of TRAVIS_COMMIT_RANGE might it make sense to go back until the nearest merge commit?
427 2017-05-01T19:17:30  <cfields> BlueMatt: why? I believe TRAVIS_COMMIT_RANGE includes the merge commit it creates
428 2017-05-01T19:17:43  <BlueMatt> well i meant eg for private repo runs
429 2017-05-01T19:17:51  <BlueMatt> it'd be nice, but i guess doesn't matter /that/ much
430 2017-05-01T19:17:58  <BlueMatt> it just feels weird that it would only be tested on prs
431 2017-05-01T19:18:21  <cfields> BlueMatt: ah, I hadn't even considered non-PRs. Yes.
432 2017-05-01T19:19:00  <cfields> BlueMatt: can probably diff to branch point
433 2017-05-01T19:19:01  <SopaXorzTaker> the addresses belong to gmaxwell and jgarzik, and one more
434 2017-05-01T19:19:08  <SopaXorzTaker> let's extort them, muhahah
435 2017-05-01T19:19:20  <SopaXorzTaker> (offtoipic end)
436 2017-05-01T19:19:30  <BlueMatt> cfields: i guess doesnt matter for first version in pr
437 2017-05-01T19:22:06  <BlueMatt> cfields: hmmm, I cant run the script locally
438 2017-05-01T19:22:06  <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.
439 2017-05-01T19:22:12  <BlueMatt> I get "bash: !b}: event not found"
440 2017-05-01T19:23:26  <SopaXorzTaker> ROLL, ROT, SWAP
441 2017-05-01T19:23:27  <cfields> BlueMatt: got a branch I can look at?
442 2017-05-01T19:23:37  <BlueMatt> cfields: I'm literally just running the command manually
443 2017-05-01T19:23:47  <SopaXorzTaker> that's a lifetime of a TX script in a nutshell
444 2017-05-01T19:23:49  <BlueMatt> https://github.com/bitcoin/bitcoin/pull/10189/files#diff-6f65a3cbb40a72a97be8d4930d214685R25
445 2017-05-01T19:23:51  <BlueMatt> that line fails
446 2017-05-01T19:24:39  <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
447 2017-05-01T19:26:02  <SopaXorzTaker> +
448 2017-05-01T19:26:59  <cfields> BlueMatt: hmm, unsure. Does it object to the sed syntax?
449 2017-05-01T19:27:20  <BlueMatt> cfields: yes, I assume its the last part of the sed line (that is the only place with a !b)
450 2017-05-01T19:27:30  <BlueMatt> but its bash complaining, not sed
451 2017-05-01T19:30:27  <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?
452 2017-05-01T19:31:00  <BlueMatt> using ' ' where?
453 2017-05-01T19:31:05  * BlueMatt is not fluent in sed
454 2017-05-01T19:31:17  <cfields> BlueMatt: sec
455 2017-05-01T19:33:04  <cfields> yea, i can reproduce when running the sed script by hand. Must be some interactive/non-interactive difference
456 2017-05-01T19:33:13  <BlueMatt> oh strange
457 2017-05-01T19:33:38  <cfields> BlueMatt: https://pastebin.com/raw/q9N6NE4b
458 2017-05-01T19:34:04  <BlueMatt> ah, heh
459 2017-05-01T19:34:11  <BlueMatt> s'pose i should have tried that
460 2017-05-01T19:38:05  <cfields> I'll fix that and add a quick change to make it only run on PRs
461 2017-05-01T19:38:22  <BlueMatt> thanks
