nine Versioning of native libraries is a mess. File names of shared libraries contain a version, e.g. libssl.so.1.1. A change in that version by definition means a change in the API. So ostensibly NativeCall users should explicitly state the version of the native library they want to access, e.g. is native('ssl', v1.1) 11:45
Now to stay with OpenSSL, the module actually supports two version: 1.0 and 1.1. That's not something NativeCall supports so we'd need a workaround like trying v1.1. first, call a function from that library (because NativeCall will only then actually load the lib) and fall back to the older version on failure. 11:46
lizmat perhaps warn if no version is specified ?
nine But hold on! On openSUSE Tumbleweed for exapmle I do not have a libssl.so.1.0 but a libssl.so.1.0.0 instead! 11:47
Best case, OpenSSL really did change their stance on what version level constitutes an API change and the docs tell you to use 1.0.0 or 1.1. Have to check that. 11:48
Worst case, they don't and there's just no way to know what the library is actually called. 11:49
So how does this work in C?
For compiling sources from C, you need to have the libopenssl-devel package installed. That package contains a symlink libopenssl.so -> libopenssl.so.1.1. So that's what your program will link against. 11:50
For a packager this means that we'd need a BuildRequires: libopenssl-devel and a Requires: libssl.so.1.1()(64bit), but we can only determine the latter when libopenssl-devel is installed 11:54
Packaging such C programs works nicely because rpm contains dependency generators. It will automatically create that Requires dependency by scanning the compiled libraries and binaries. 11:57
Btw. it actually also contains a dependency generator for Perl, but that's disabled because presumably the hacky way it parses Perl code for use-lines didn't work all that well
12:03 AlexDaniel left
nine At least the thing is pluggable. You essentially drop a little description file in a directory telling rpmbuild that for .rakumod files it should call a certain script for getting the dependencies 12:05
WRT OpenSSL I really don't know how to continue. I do have a working patch for trying 1.1 and 1.0 at compile time. It would fix github.com/sergot/openssl/issues/59 and github.com/sergot/openssl/issues/54 and github.com/sergot/openssl/issues/16 12:43
But I'm not sure that's actually the right way, as like I said, building C code requires that -devel or -dev package to be installed, too. Things are basically confused by our build and runtime phases being much closer 12:44
12:45 sena_kun left
nine OTOH 12:50
Ironically it is so confusing exactly because we go a step further than C. With C code there's simply no formalized way to say "I need library X in version Y or above". That's left for the configuration system (e.g configure.sh) or ultimately the documentation or even experimentation to handle. 12:52
If we didn't have the possibility to specify versions, we'd just require those symlinks (from the -devel packages) and confuse the user with failures if the version is inappropriate. 12:54
But since we do support specifying versions, we now face the question on when it is actually appropriate to do so. Something I think no one has really answered before. 12:55

timotimo i'm super tired and my brain doesn't seem to really work yet, so i'll just toss this out there: anybody want to look into making class/role/whatever bodies not be called during deserialization if they are empty? could be something the static optimizer can do, could be something we can already figure out during stage parse 13:07

patrickb I got the idea from a friend of mine who works at a very large company. Each software people use has to be approved first. Apache is on the list of approved software, raku isn't.
So if there would be an mod_moar he'd be able to use raku. 19:42

timotimo MasterDuke:we generate a frame called <deserialization+dependencies> or so, find it in moar --dump 21:27
MasterDuke i see it 21:30
21:44 patrickb left
MasterDuke timotimo: but i'm not seeing where any of the method referenced in that frame execute anything 21:45
timotimo sorry, what exactly are you missing? 21:54
MasterDuke you were saying something about making deserialization not execute compunits with empty bodies? 21:57
timotimo yeah, it's about 15kb into the frame where it starts doing The Thing 21:58
it looks like "prepargs Callsite_4", "invoke_v loc_4495_obj", line number annotation, prepargs, invoke_v, annotation, prepargs, invoke_v, annotation, etc etc 21:59
Scalar.pm6:1, Scalar.pm6:36, Scalar.pm6:37, Scalar.pm6:38, Scalar.pm6:39, Scalar.pm6:39, ... 22:00
those lines are all "my class XYRef { }"
IntLexRef, NumLexRef, etc
oh, maybe your --dump output is getting cut off; you may have to redirect it to a file i think? 22:01
MasterDuke hm. there aren't any invoke_v in my output 22:02
timotimo ah, right
it's actually in <unit>, not in <dependencies+deserialize>
MasterDuke fwiw, i was running `moar --dump perl6.moarvm -e ''` in my rakudo folder 22:03
oh, and that doesn't have any <unit>
timotimo oh 22:04
i was talking about the core setting
what you have there is actually code compiled with nqp i think?
MasterDuke heh, that would make sense 22:05
timotimo oh, also the number at the start isn't bytes, it's just instruction number 22:06
there's also one frame that's got above 32k instructions that are just getcode and push_o over and over 22:07
this could shrink slightly in bytecode size if a pushcode op were introduced 22:08
it'd go from instruction + register + frame + instruction + register + register to just instruction + register + frame
it's 6 bytes each for getcode and push_o, and it'd be 6 for pushcode, so it'd go down to roughly half 22:09
now, pushing one code will cost 6 then, instead of 12, but if there's a push16code op that takes 16 frames, it'd cost 2 + 2 + 16 * 2, which divided back by 16 is 16 1/16th or so? 22:11
what could be even better is just serializing an array that has the frame numbers in the right order and do all the work with just a single op; that'd also allow using the sligthly better int array serialization for this task
MasterDuke i must admit i'm slightly distracted by trying to turn my new RPi 3b+ into an access point 22:13
timotimo hmm, we've got the numbers 0 through roughly 16.5k
no problem; also perhaps i should move the rambling to #moarvm
