72018-01-04T00:07:31 <TD-Linux> I don't think there are any obvious mitigations that bitcoin core can do that it doesn't already (like keeping unencrypted keys in memory for short times)
82018-01-04T00:08:26 <promag> macos not affected?
92018-01-04T00:08:37 <achow101> promag: it's a hardware bug, all OSes affected
102018-01-04T00:09:04 <promag> sorry, there is "os x" reference there
112018-01-04T00:09:14 <TD-Linux> apple has been silent so far. but you can assume that it's affected and not patched.
122018-01-04T00:09:29 <promag> right

162018-01-04T00:18:06 <phantomcircuit> TD-Linux, only thing to do is detect the failure and exit
172018-01-04T00:18:10 <phantomcircuit> but even that is basically useless
182018-01-04T00:19:09 <TD-Linux> all of the large VM providers are already patched, so I don't think there is any useful action to take.

2622018-01-04T11:09:37 <wumpus> ^^ those kind of spurious PRs are the only kind that really annoy me
2632018-01-04T11:09:42 <zelest> I just wish to remove as much clutter as possible when it comes to documentations. :)
2642018-01-04T11:09:51 <zelest> hehe
2652018-01-04T11:10:07 <wumpus> I agree, but I don't think it's clutter, just try to move it to a place it won't be in the way when just following the guide
2662018-01-04T11:10:49 <wumpus> we don't have the capacity to act as tech support so anything that pre-empts issues that people might have is a win
2672018-01-04T11:11:00 <zelest> Yeah, but the clang thing.. why does the user need to know what the compiler is capable of since what version of openbsd? :)
2682018-01-04T11:11:24 <wumpus> you could shorten it, the point is that people are bound to forget the CC=cc CXX=c++ thing
2692018-01-04T11:11:42 <wumpus> if they do, they end up in a situation where e.g. berkeleydb is built using gcc, and bitcoind using clang
2702018-01-04T11:11:48 <wumpus> then they'll have linker errors
2712018-01-04T11:11:58 <zelest> hmms, yeah, true

2732018-01-04T11:12:27 <wumpus> the underlying issue is that openbsd 6.2 still has the gcc compiler, if it didn't, this wouldn't be an issue at all. Maybe for the next release it'll really go away?
2742018-01-04T11:12:41 <wumpus> but for now, as long as gcc 4.2 is still installed, we need it
2752018-01-04T11:13:05 <zelest> it will probably be there for quite some time
2762018-01-04T11:13:22 <zelest> the whole ports tree and all the different architectures they build on
2772018-01-04T11:13:31 <wumpus> and automake/autoconf tends to choose gcc over cc if it can
2782018-01-04T11:13:38 <wumpus> which is terrible in this specific case
2792018-01-04T11:13:51 * zelest nods

3102018-01-04T12:19:28 <Varunram> Asking this because I happened to connect to Peter Todd's seed and got redirected to an abc seed

3142018-01-04T12:22:10 <Varunram> hm, bad language on my part I guess. So a related question would be what actually happens when I try to connect to a testnet seed? (you can answer at #bitcoin if its off-topic :) )

3172018-01-04T12:24:12 <wumpus> in principle the DNS seeders should avoid reporting nodes that are on forks, but in the current implementation this is based on service bits, they don't actually (Afaik) check what chain they're on
3182018-01-04T12:26:34 <Varunram> oh, alright. Weird thing was it didn't spawn an error (might be someone messing with the banner). Our fault I guess. Thanks!

3722018-01-04T14:35:03 <sdaftuar> luke-jr: not sure if my memory is failing me, but i believe p2wsh uses a single sha256 of the script, no?
3732018-01-04T14:35:36 <sdaftuar> (anyway this is the first i've heard of the p2sh^2 idea, so i can't comment on your question generally)
3742018-01-04T14:36:45 <sipa> i don't think relying on relay policy to prevent data storage is very realistic
3752018-01-04T14:37:06 <sipa> at best it will make miners create websites where you can submit things

3772018-01-04T14:37:10 <luke-jr> relay+miner policy; realistic or not, having it as an option is helpful
3782018-01-04T14:38:18 <luke-jr> it might not help much with our current problems, but in the future it could become valuable
3792018-01-04T14:39:24 <luke-jr> sdaftuar: elaborated more on my bitcoin-dev post; from the BIP, it doesn't seem to use single SHA256
3802018-01-04T14:42:07 <sipa> luke-jr: it's also fundamentally incompatible with one of bech32's design goal: being forward compatible with future witness versions that may use dofferent hashing schemes
3812018-01-04T14:42:15 <sipa> *different
3822018-01-04T14:43:37 <luke-jr> sipa: but not forward compatible with this scheme :x
3832018-01-04T14:44:00 <luke-jr> what if we define the first decoded data value being 17 or 18, to P2SH^2 modes?
3842018-01-04T14:44:27 <luke-jr> or something like that
3852018-01-04T14:44:42 <sipa> meh, that would be possible, but won't be extensible to newer witness versions (which i exoect will be proposed soon anyway)
3862018-01-04T14:45:27 <luke-jr> could do 17 to indicate "additionally SHA256 hash", 18 to indicate "additionally RIPEMD160 hash", and then have a byte following it be the witness version

4822018-01-04T19:02:43 <kanzure> hi.
4832018-01-04T19:02:53 <instagibbs> hi
4842018-01-04T19:02:58 <cfields> yet another quick codesigning update
4852018-01-04T19:03:07 <jonasschnelli> #topic code signing
4862018-01-04T19:03:41 <cfields> I've got the csr patching worked out, and gmaxwell is currently working on documenting the keygen process
4872018-01-04T19:03:54 <jonasschnelli> nice!
4882018-01-04T19:04:05 <cfields> Ideally we'd get that worked out in the next few days
4892018-01-04T19:04:24 *** zautomata1 has joined #bitcoin-core-dev
4902018-01-04T19:04:34 <jonasschnelli> Good. I think there is no need for rush things,... ideally, we would have the new cert for the 0.16 (or say 16.) release
4912018-01-04T19:04:36 <cfields> jonasschnelli: is apple's signing process automated and pretty quick, i hope?
4922018-01-04T19:04:49 <achow101> Do we have a new Apple cert? It expires in a few days
4932018-01-04T19:04:50 *** dqx has joined #bitcoin-core-dev
4942018-01-04T19:04:51 <cfields> jonasschnelli: well the current cert expires on the 11
4952018-01-04T19:04:52 <jonasschnelli> cfields: once we have the csr, ... it's a matter of seconds
4962018-01-04T19:05:05 <meshcollider> achow101: we don't need it until 0.16
4972018-01-04T19:05:07 <jonasschnelli> achow101: expiring only matter for new binaries
4982018-01-04T19:05:11 <cfields> it's not a huge issue as we're not ready to release yet, ofc
4992018-01-04T19:05:17 <cfields> right
5002018-01-04T19:05:22 <achow101> meshcollider: jonasschnelli right, duh
5012018-01-04T19:05:25 *** dqx has quit IRC
5022018-01-04T19:05:31 <cfields> I'd still like to avoid a lapse if possible, though
5032018-01-04T19:05:34 *** dqx has joined #bitcoin-core-dev
5042018-01-04T19:05:47 <cfields> note that we also have the actual signing process to deal with
5052018-01-04T19:05:48 <jonasschnelli> yes. In "emergency" cases, we can still create a single-person RSA cert...
5062018-01-04T19:05:49 <achow101> although sooner is better. otherwise it becomes a release blocker
5072018-01-04T19:06:12 <cfields> luckily I hacked up the mac codesigner last year, but it needs a bit of polish
5082018-01-04T19:06:27 <jonasschnelli> achow101: Yes. Though we have the fallback doing the same as we already did (single person RSA cert)
5092018-01-04T19:06:40 *** zautomata has quit IRC
5102018-01-04T19:07:01 <jonasschnelli> How about Windows?
5112018-01-04T19:07:04 <cfields> the only snag is that it doesn't handle timestamping. So worst-case, we may do a non-timestamped 0.16. It could be followed up with a timestamped release once that's worked out
5122018-01-04T19:07:24 <jonasschnelli> Timestamping of what?
5132018-01-04T19:07:32 <cfields> imo we should go ahead and do Windows once we've gone though the process for osx and identified the kinks

5152018-01-04T19:07:57 *** alcipir has joined #bitcoin-core-dev
5162018-01-04T19:08:05 <jonasschnelli> I have no insights how Windows code signing works... but probably the same RSA approach could be taken, right?
5172018-01-04T19:08:10 <cfields> windows uses a free/open-source signer though, so that's no concern
5182018-01-04T19:08:26 <cfields> yea, ideally we'd use the same procedure for both
5192018-01-04T19:08:30 * jonasschnelli curses apple closed source signing
5202018-01-04T19:08:59 <cfields> it's possible that it's just an hour's worth of work. I just haven't looked into apple's timestamping mechanism yet

5222018-01-04T19:09:59 <cfields> ok, that's it from me

5252018-01-04T19:10:17 <jonasschnelli> Any other topics?
5262018-01-04T19:10:40 <achow101> coin selection
5272018-01-04T19:10:43 *** dqx has joined #bitcoin-core-dev
5282018-01-04T19:10:52 <Murch> Hi :)
5292018-01-04T19:10:53 <jonasschnelli> #topic coin selection (murchs algo)
5302018-01-04T19:11:06 <meshcollider> Perfect timing Murch ;)
5312018-01-04T19:11:11 <jonasschnelli> heh
5322018-01-04T19:11:17 <Murch> Highlight on "coin selection" ;)
5332018-01-04T19:11:26 <achow101> I did a bunch of simulations https://github.com/bitcoin/bitcoin/pull/10637#issuecomment-353989346
5342018-01-04T19:11:37 <achow101> I'm not quite sure how to interpret the results
5352018-01-04T19:12:20 <achow101> but it basically looks like it performs no worse than the current algo
5362018-01-04T19:12:24 <jonasschnelli> Maybe Murch can comment on your results?
5372018-01-04T19:12:32 <achow101> It looks like it usually does slightly better since BnB is hit a small percentage of the time
5382018-01-04T19:13:02 <Murch> achow101: If you're only simulating flat fees the only thing that you're counting is the number of transactions that don't create a change output.
5392018-01-04T19:13:36 <achow101> Murch: I've only simulated flat fee so far. Maybe I should try it with somehow using mainnet fee estimation?
5402018-01-04T19:14:12 <Murch> achow101: What would be really interesting is whether the different selection algorithm has an impact on the cost in varying fee levels, because it could cause BnB to select more unspents at a higher fee level and fewer at a lower level, which would only be visible in a scenario of varying fee levels.
5412018-01-04T19:14:25 <achow101> If people would like to run their own simulations, the code for it is available here: https://github.com/achow101/bitcoin/tree/bnb-simulate. More info in this commnet: https://github.com/bitcoin/bitcoin/pull/10637#issuecomment-353452113
5422018-01-04T19:14:41 <Murch> That's at least my main concern in regard to deploying BnB.
5432018-01-04T19:14:50 *** dqx has quit IRC
5442018-01-04T19:15:25 <achow101> Murch: I did run the simulation at different flat fee rates
5452018-01-04T19:15:29 <provoostenator> Vaguely related question: is it possible to refactor the coin selection algo into a pure function that takes whatever info it needs (coins, mempool stats, etc) as input and returns the coins? That might make it easier to try different algos.
5462018-01-04T19:15:30 <achow101> *simulations
5472018-01-04T19:15:40 *** dqx has joined #bitcoin-core-dev
5482018-01-04T19:16:25 <Murch> achow101: Yes, I see that. But the selection effect would only be visible in a scenario with changing fees.
5492018-01-04T19:16:28 <jonasschnelli> provoostenator: also in the past, there where discussions about having multiple coin selection
5502018-01-04T19:16:35 <jonasschnelli> *selections
5512018-01-04T19:16:51 <provoostenator> Right, that would be the idea. Easier to add more experimental selection mechanisms.
5522018-01-04T19:16:55 <achow101> Murch: ah, right
5532018-01-04T19:17:06 <instagibbs> provoostenator, standard coin selection right now is a loopy affair, kind of complicated :/
5542018-01-04T19:17:30 <Murch> provoostenator: achow101's implementation does a big step in that direction .
5552018-01-04T19:18:18 <jonasschnelli> other topics?
5562018-01-04T19:18:51 <Murch> @achow101: The table seems to show only the final UTXO count, right?
5572018-01-04T19:19:17 <Murch> Interesting would also be the final balance of the wallet, especially in regard to the scenario with varying fee levels.
5582018-01-04T19:19:18 <achow101> Murch: it shows all of the same things that your simulation framework outputs
5592018-01-04T19:19:20 <achow101> I think
5602018-01-04T19:19:44 <achow101> It's a big table, you'll have to scroll
5612018-01-04T19:19:54 <Murch> Perhaps we could put our heads together in the next few days.

5662018-01-04T19:20:37 <Chris_Stewart_5> provoostenator: So basically you pass in a higher order function to the actual 'read from wallet' function
