  22020-11-20T00:01:08  <miketwenty1> makes sense
  32020-11-20T00:03:11  <miketwenty1> so you would sign the binaries and places like bitcoin-core.org would have access to achow101's signed exe.. if i follow
  42020-11-20T00:04:19  <sipa> all the release binaries are signed
  52020-11-20T00:05:12  <sipa> but they're created in a 3-step gitian process; (a) people build and agree on an unsigned build (b) achow signs the binary that comes out and publishes the signature (c) people create a signed build by combining their unsigned binaries with the posted signature
  62020-11-20T00:05:59  <miketwenty1> i look forward to learning the process of (c)
  72020-11-20T00:06:07  <sipa> it's just gitian
  82020-11-20T00:06:49  <miketwenty1> what does that mean? "automated"?
  92020-11-20T00:06:52  <sipa> https://github.com/bitcoin/bitcoin/blob/master/contrib/gitian-descriptors/gitian-win.yml for the unsigned build, https://github.com/bitcoin/bitcoin/blob/master/contrib/gitian-descriptors/gitian-win-signer.yml for the signed one

 482020-11-20T02:38:47  <fanquake> There should be a few updates on the macOS Guix front shortly
 492020-11-20T02:38:53  <luke-jr> wumpus: don't see anything there related?
 502020-11-20T02:39:24  <luke-jr> wumpus: I mean macOS ARM
 512020-11-20T02:39:32  <luke-jr> that they just started selling recently
 522020-11-20T02:39:49  <wumpus> no idea then
 532020-11-20T02:40:10  <wumpus> macos ARM used to be iOS
 542020-11-20T02:40:24  <wumpus> I don't exactly keep day to day track of what apple is doing fwiw :-)
 552020-11-20T02:40:26  <sipa> are they actually for sale already?
 562020-11-20T02:40:32  <sipa> i thought they were just announced
 572020-11-20T02:41:55  <wumpus> but of course, if that becomes their new architecture then we should support that too
 582020-11-20T02:42:11  <fanquake> according to the apple website I can buy one now
 592020-11-20T02:42:46  <achow101> they're on sale now
 602020-11-20T02:42:56  <sipa> i just mean it's probably hard to for us test anything as long as none of us have hardware
 612020-11-20T02:43:05  <sipa> unless there is some sort of simulator
 622020-11-20T02:43:11  <achow101> I thought provoostenator got the dev kit
 632020-11-20T02:43:47  <sipa> ah cool
 642020-11-20T02:43:52  <achow101> in theory we shouldn't need to do anything for now because of their x86 emulator
 652020-11-20T02:44:14  <luke-jr> achow101: good luck with IBD
 662020-11-20T02:45:26  <luke-jr> x86->ARM isn't going to be like m68k->PPC or PPC->x86
 672020-11-20T02:45:52  <luke-jr> even if they got comparable performance, emulation is going to have a very noticable impact, especially on CPU-intensive work
 682020-11-20T02:45:53  <wumpus> native build is going to be easy, I expect, building for ARM is also not a challenge, the difficult part is likely what new things need to be reverse engineered to cross-compile for it from gitian
 692020-11-20T02:46:16  <wumpus> e.g. for their SDKs and strange toolkits
 702020-11-20T02:46:22  <luke-jr> wumpus: I kinda wonder if we can just change the CHOST target…
 712020-11-20T02:46:36  <luke-jr> I guess probably need to update the Xcode too
 722020-11-20T02:46:39  <wumpus> new kinds of 'fat executables' maybe !
 732020-11-20T02:46:46  <luke-jr> ugh
 742020-11-20T02:46:58  <fanquake> "Universal binaries"
 752020-11-20T02:46:59  <luke-jr> true, I guess we probably can't just ship two different DMGs? XD
 762020-11-20T02:48:30  <achow101> they might be enforcing notarization for arm things too?
 772020-11-20T02:48:40  <luke-jr> that'd suck
 782020-11-20T02:49:13  <luke-jr> I guess in that case we have no choice but to go along with it
 792020-11-20T02:49:24  <luke-jr> firstrun dialog warning users of Apple'
 802020-11-20T02:49:29  <luke-jr> 's privacy violations?
 812020-11-20T02:49:40  <wumpus> they really should have skipped ARM and went straight to RISC-V, of course this means they'll have to go through the process again in a few years :-)
 822020-11-20T02:50:10  <luke-jr> why would Apple care to go RISC-V?
 832020-11-20T02:51:07  <wumpus> I wasn't entirely serious
 842020-11-20T02:51:24  <wumpus> buut just there seems to be some kind of pattern there
 852020-11-20T02:52:39  <sipa> the licensing costs and closedness of ARM isn't an issue for them :)
 862020-11-20T02:52:57  <achow101> they've been making arm chips for years now
 872020-11-20T02:53:04  <sipa> also that
 882020-11-20T02:53:33  <luke-jr> I wonder if they're dropping x86 simply to consolidate back to 1 arch
 892020-11-20T02:53:56  <achow101> dunno about consolidate, but it's definitely to make the walled garden even more walled
 902020-11-20T02:54:04  * luke-jr ponders if there's any decompilers that take advantage of multiple archs
 912020-11-20T02:55:47  <achow101> wdym by "take advantage"?
 922020-11-20T02:56:05  <wumpus> yes it makes sense from an economic point of view, ARM chips are produced at much larger quantities, it's probably just a lot cheaper for them

1012020-11-20T02:58:18  <achow101> luke-jr: there's decompilers for a lot of archs
1022020-11-20T02:58:30  <luke-jr> achow101: not quite the same thing
1032020-11-20T02:58:54  <achow101> not sure what you mean then
1042020-11-20T02:58:59  <luke-jr> achow101: I mean looking at both the x86 and ARM builds of the same thing, to give better decompilation output
1052020-11-20T02:59:32  <achow101> ah. the decompilers I know of only take one binary at a time so they can't do that
1062020-11-20T02:59:37  <luke-jr> right
1072020-11-20T02:59:55  <wumpus> I do understand luke-jr's point, if you have the guarantee that the same source code is compiled to different architectures and binary formats, that might help learning more about it because the compiler might do slightly different (but deterministic) things
1082020-11-20T03:02:42  <wumpus> that said, the point of decompilation is rarely to reconstruct as much as possible about the original code, just to have a easier to read representation than assembly language

1102020-11-20T03:03:49  <sipa> if decompilers could do that, i'm sure they'd try
1112020-11-20T03:04:30  <sipa> actually, maybe not, if it were possible to reconstruct something that was more readable than the original code, but not identical, they'd do that
1122020-11-20T03:04:31  <wumpus> I read something funny about Turbo C 2.0 (or similar) once, that compiler generated such predictable code that it's possible to reconstruct the original C code (besides variable names and comments ofc)
1132020-11-20T03:05:17  <wumpus> sipa: exactly :)
1142020-11-20T03:05:52  <luke-jr> [02:57:55] <luke-jr> it's the kind of thing you'd only do for fun
1152020-11-20T03:05:54  <sipa> in such i world i expect proprietary software to be littered with dummy inline assembly
1162020-11-20T03:06:16  <wumpus> there is the business case 'I lost the source code and want to reconstruct it' but I expect it's a fairly rare use of decompilers, most use is for figuring out malware

1192020-11-20T03:07:09  <luke-jr> wumpus: meh, don't really even need a decompiler for that
1202020-11-20T03:07:24  <wumpus> didn't know it was based on decompilation though

1232020-11-20T03:07:57  <wumpus> luke-jr: no on 'needs' a decompiler, it's kind of a luxury but can definitely speed up things (for people that have to do that work all day)
1242020-11-20T03:08:00  <luke-jr> capture the flag?

1402020-11-20T03:13:03  <miketwenty1> is there a magic number before i should add myself fanquake?
1412020-11-20T03:13:06  <wumpus> if emzy is building but not on there you could prod them to add themselves
1422020-11-20T03:13:16  <wumpus> 3 or so

1492020-11-20T03:15:03  <sipa> ah, so the Apple ARM stuff needs macOS 11, not 10.x
1502020-11-20T03:15:14  <miketwenty1> i just got done watching mandalorian.. im thinking if i get my name on this list i can get my beskar armor
1512020-11-20T03:15:16  <sipa> so i guess we'll need to build that with a later xcode
1522020-11-20T03:15:44  <sipa> but apart from that, i do expect it to be simple (as long as Qt etc support it)
1532020-11-20T03:16:06  <wumpus> right it doesn't have to be a great number of builds just to prove that a) you can do gitian builds b) you're willing to do them regularly, just to make sure you're not wasting people's time adding the signature
1542020-11-20T03:16:09  <achow101> i expect apple will have done something that just makes it super painful

1612020-11-20T03:23:50  <wumpus> yeah
1622020-11-20T03:24:18  <wumpus> even the plists are still a continous source of fun
1632020-11-20T03:24:27  <sipa> well, all things we can figure out once someone has hardware
1642020-11-20T03:32:30  <wumpus> I think that's a good way to go about it, no need to be overly eager anyhow, wait a bit for the initial bugs and tooling issues for the platform to be ironed out by others
1652020-11-20T03:33:52  <fanquake> Yea. Like having your macbook bricked after upgrading to macOS 11
1662020-11-20T03:34:32  <wumpus> sorry for your loss :/
1672020-11-20T03:35:02  <fanquake> heh no, I'm remaining firmly on macOS  10. I'll think about an upgrade after a few point releases.
1682020-11-20T03:35:15  <fanquake> Just seen reports of bricking in older macbooks

1852020-11-20T04:22:39  <wumpus> I really prefer not to see it on the last minute PRs list for the 22.0 milestone *again* :-)
1862020-11-20T04:23:50  <wumpus> I'm sure we can simplify things like that later
1872020-11-20T04:24:41  <miketwenty1> has anyone here used terraform?
1882020-11-20T04:28:16  <wumpus> fanquake: but agree it's become a horrible mess; at some point we'd likely want to do real ELF parsing instead of parsing the output of readelf, I think in many cases it's easier
1892020-11-20T04:29:00  <wumpus> no need for regexps in any case
1902020-11-20T04:29:26  <luke-jr> regexps are better than error-prone parsing :x
1912020-11-20T04:30:04  <wumpus> they're just as error prone just hide this by being inscrutinable too

2002020-11-20T04:39:29  <luke-jr> wumpus: not really
2012020-11-20T04:40:55  <wumpus> in any case, parsing command output text was the wrong way to go about this (this is my fault, it seemed easier when it was still a few simple checks, it always starts out like that doesn't it)
2022020-11-20T04:41:22  <luke-jr> parsing ELF sounds a lot harder tho
2032020-11-20T04:41:43  <wumpus> it's really easy
2042020-11-20T04:41:49  <wumpus> just some fixed binary headers
2052020-11-20T04:42:31  <wumpus> that we only handle a small subset of possible architectures makes it even simpler
2062020-11-20T04:43:00  <sipa> yeah and then some architecture is added with 9-bit bytes, and all your parsing code breaks!
2072020-11-20T04:43:43  <wumpus> I'm sure readelf would choke on that too :)
2082020-11-20T04:46:33  <sipa> wumpus: are you up early, or up late?
2092020-11-20T04:47:55  <wumpus> but joking aside the ELF format has been really stable since, 1995 or so (when spec 1.2 was released), of course there have been some platform-specific extensions but the essence is still exactly the same, there's not many data formats that stable
2102020-11-20T04:47:59  <wumpus> sipa: very early

2472020-11-20T05:22:52  <wumpus> of course, genisoimage will have an important part in creating the dmg
2482020-11-20T05:23:43  <fanquake> have been chatting to Carl, and I think we are going to revive some of #18151, so we can dump genisoimage

2522020-11-20T05:24:14  <fanquake> rather used some  tools that are being actively maintained

I compile like this:  ./autogen.sh && ./configure CC=gcc-8 CXX=g++-8 BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include" && make -j10

3552020-11-20T07:59:16  <hebasto> catching up the macos non-deterministic gitian builds (4 sigs vs 2 sigs). Do I understand correctly that we blame llvm?
3562020-11-20T08:04:46  <fanquake> hebasto: that's correct. I'll make sure to summarize in an issue on the repo once I've talked to Carl / Cory. They were debugging the same issue earlier from what I can tell.
3572020-11-20T08:05:20  <hebasto> fanquake: thanks
3582020-11-20T08:08:19  <jonasschnelli> fanquake: is 0.21.0rc1 mac non deterministic? Shall I wait with the code signatures?
3592020-11-20T08:11:15  <fanquake> jonasschnelli: yea it is. We think it's an issue in LLVM 8. I don't think you necessarily have to wait with the sigs, as the fix could be involved, and we've had non-determinism in an rc before. However up to you.
3602020-11-20T08:12:23  <fanquake> We've already got an rc2 happening because of some wallet fixes, and now the non-determinism, so we could probably even just skip the signed binaries for rc1

4542020-11-20T12:12:39  <fanquake> heh pixie
4552020-11-20T12:15:04  <Kiminuo> hmm, this seems to be the magic formular to compile code <filesystem> on Ubuntu 18.04: "g++-8 --std=c++17 main.cpp -lstdc++fs" ... now there must be an easy way to specify it for Bitcoin core build. I have tried:  ./autogen.sh && ./configure CC=gcc-8 CXX="g++-8" LDFLAGS="-lstdc++fs" --with-incompatible-bdb && make -j10
4562020-11-20T12:15:05  <Kiminuo>  but apparently that's not it
4572020-11-20T12:15:23  <Kiminuo> any tips?
4582020-11-20T12:16:55  <wumpus> 😈

4632020-11-20T12:20:43  <wumpus> Kiminuo: weird, LDFLAGS should work to specify an additional library
4642020-11-20T12:23:12  <wumpus> Kiminuo: you've checked make V=1 to see if it doesn't get passed at all?
4652020-11-20T12:23:13  <Kiminuo> "g++-8 --std=c++17 -lstdc++fs main.cpp" this fails with the similar errors as " ./autogen.sh && ./configure CC=gcc-8 CXX="g++-8" LDFLAGS="-lstdc++fs" --with-incompatible-bdb && make -j10"
4662020-11-20T12:23:29  <wumpus> okay
4672020-11-20T12:23:52  <Kiminuo>  LDFLAGS       = -lpthread  -Wl,-z,relro -Wl,-z,now -Wl,-z,separate-code -pie   -lstdc++fs
4682020-11-20T12:23:57  <Kiminuo> this is reported by ./configure
4692020-11-20T12:24:05  <wumpus> looks okay to me
4702020-11-20T12:24:05  <Kiminuo> so I think it is added ok
4712020-11-20T12:25:14  <Kiminuo>  CXX           = g++-8 -std=c++17
4722020-11-20T12:25:19  <Kiminuo> this is also from the configure
4732020-11-20T12:25:28  <Kiminuo> should "std" be with two hyphens?
4742020-11-20T12:25:37  <Kiminuo> like this:  CXX           = g++-8 --std=c++17
4752020-11-20T12:25:37  <Kiminuo> ?
4762020-11-20T12:26:14  <Kiminuo> https://stackoverflow.com/questions/53201991/how-to-use-stdfilesystem-on-gcc-8 ... some guy wrote "--std=c++17 -lstdc++fs"
4772020-11-20T12:26:19  <Kiminuo> so not sure
4782020-11-20T12:27:18  <Kiminuo> seems like one hyphen is ok

4832020-11-20T12:36:06  <fanquake> Cory has confirmed that the macOS determinism issue is the same one him and Carl had seen, and bisected to a commit in LLVM. Possible that we might be able to get away with a workaround in Qt rather than having to either switch to a newer compiler, or build our own.
4842020-11-20T12:36:14  <fanquake> He said he could open an issue on the repo with some more details.

5892020-11-20T17:11:05  <luke-jr> wumpus: thoughts on using 0.20.2 & 0.21.0 as a trial run for how fast users could upgrade for Taproot?

5912020-11-20T17:11:35  <luke-jr> maybe release notes could include a short paragraph to this effect

5932020-11-20T17:17:25  <aj> luke-jr: they're both important preparatory steps before deploying taproot (0.20.2 avoids network spam, 0.21.0 shakes out the major upgrade bugs), so not sure it's even a "trial" rather than the first leg of the relay or something?

5952020-11-20T17:24:24  <luke-jr> aj: I mean in the sense of "If you want Taproot activated sooner, upgrade ASAP to show how quickly deployment can happen"
5962020-11-20T17:25:50  <aj> luke-jr: yeah, i just mean that you should be upgrading to those versions for practical reasons anyway, not just because of how people might read the stats later
5972020-11-20T17:27:34  <luke-jr> aj: perhaps, but without a kick like this, I'm not sure many people will see it that way
5982020-11-20T17:27:54  <luke-jr> or might figure "I'll just wait and upgrade immediately when activation is released"

6812020-11-20T19:39:56  <wumpus> no, no one is keeping download statistics

6832020-11-20T19:42:47  <wumpus> there are no trackers or anything on the site; it's sometimes inconvenient but for a project like this it's very important to stay above the table in that regard

6852020-11-20T19:43:36  <miketwenty1> i see.. im guessing you help run the downloads available on bitcoincore.org?
