nine Looks like by hunch was right: I figured that inexplainable issues with attributes are most probably caused by invalid or incomplete type composition information and indeed, adding the auto_viv_container info changes the error. 09:28
It's now: "assign requires a concrete object (got a Any type object instead)" instead of "assign requires a concrete object (got a VMNull type object instead)"
There's also a bug in Metamodel::Primitives.compose_type: Cannot resolve caller to_vm_types(Mu:U) 09:36
As Mu is in the mro of....everything, it must be part of the type configuration

nine And another bug: it deconts everything. But in the case of auto_viv_container we must not do that, lest we lose the container it ought to contain 09:51
Fixing that gets me to "Cannot assign to a readonly variable or a value"

nine Finally! 12:58
lizmat ein Aha! Erlebnis? 12:59
nine It was indeed more issues with Metamodel::Primitives.compose_type. The for %hash.kv -> $k, $v in sub to_vm_types(%hash) caused the original Scalar container of the attribute to be replaced with a read-only Scalar container. 13:01
Changing that to for %hash.kv -> $k, \v keeps the container intact.
Fair to say: writing a fully fletched meta class in Raku remains hard 13:02
jnthn
.oO( I didn't find all the fully fledged ones I wrote in NQP all that easy... :P )

Kaiepi jnthn, are the issues you mentioned with github.com/rakudo/rakudo/pull/3451 and friends fixed now? 14:03
and yeah, metaclasses aren't all that easy to write :P 14:06
that reminds me, Metamodel::Primitives is still lacking methods exposing nqp::can and the parameterization ops 14:07
jnthn I'd not do nqp::can, I dunno if it's going to survive the dispatcher re-think. 14:11
AlexDaniel moritz: so you probably want to git pull to get at least this commit: github.com/moritz/perl6-all-module...c464745f42 14:13
moritz: now, I tried running it with --ignore-errors and it was able to finish with 500+ new commits
moritz: so I'd like to know how exactly it fails for you 14:14
it did ask for credentials a few times and I just pressed enter 14:15
no idea if you're seeing the same in different for or what
form*
nine Oh, so many passing tests :) Next up: Calling methods on Perl 5 subclasses of Raku extended Perl 5 classes leads to infinite loops. I think I could get around that by mirroring the inheritance structure on the Raku side. 14:43
I love how the solutions in this new implementation generally fall in the category of "do things properly" instead of hacks 14:46
jnthn nine++ 14:48
[Coke] nine++ 14:51
Kaiepi ooo if nqp::can's not going to survive a few of my modules will need updating 15:00
nine That's the price for using nqp 15:02
Kaiepi yep 15:03
it wasn't something i could really avoid
how will checking if methods exist on any metaobject work with the dispatching rethink? 15:04
timotimo nqp::can is gonna get canned!
MasterDuke will we do a can-can to celebrate? 15:05
nine Kaiepi: that's a trap we all fall into and will pay the price for eventually. The correct solution would not have been "ok, I'll use nqp then" but adding the desired functionality to rakudo.
Kaiepi ah 15:06
nine At least when I've directly accessed the multidispatch cache, I've done so defensively: github.com/niner/Inline-Perl5/blob...HOW.pm6#L4 15:07
Kaiepi nice 15:08
with that and Metamodel::Primitives exposing parameterization ops, Kind, Kind::Subset::Parametric, and Data::Record have no need for nqp anymore 15:09
nine Took me quite a while to find a precompilation friendly way of gracefully handling those compilation errors...
Kaiepi Trait::Traced needs nqp as well for some reason, but i forget why... it was something fairly minor
i think it unboxes a string somewhere, but wouldn't assigning a Str:D to a str work? 15:11
nine think so

nine And subclasses work. This was not nearly as bad as I expected 16:01
Last failure: not ok 20 - Destructor ran
And it looks like that's not even a memory leak. We just fail to call the base class' destructor 16:20
Ah yes, those need to be called manually in Perl 5 if a subclass has a DESTROY method. Another bug unearthed by unifying stuff 16:23

patrickb: maybe just make a ticket about the need to get it done right and assign it to me.
patrickb vrurg: Will do! 19:30
vrurg patrickb: Looking at your patch. You shouldn't use $config instead of $nqp_config in configure_moar_backend because then you make backend-specific things global with risk to override something. 19:32
$nqp_config is actually $self->{impls}{moar}. Content of this hash is visible in template under for_backends macro. I.e. those values are just context-dependent. Sure, you can't see them anywhere else. 19:34
patrickb vrurg: OK, will try to refactor accordingly. 19:35
$self->{impls}{moar}{config} or $self->{impls}{moar}?
vrurg patrickb: config because this is what is visibile through @var@ in templates. 19:37
{impls}{moar} is for internal script use.
patrickb ok

nine MasterDuke: I'd ignore the error message and compare bytecode files
MasterDuke the $hll differs 20:09
but that's just an index into the string heap, right? 20:10
nine yes 20:11
But still...why would it differ?
You should get 100 % identical output
MasterDuke because it's added to the string heap at a different time i assume. at the end of all the other writing, instead of before 20:12
nine Ok, that makes sense indeed. Of course that doesn't make the hunt any easier 20:13
MasterDuke yeah. next difference isn't until a bunch of bytes later, outside the header i believe 20:16
nine And now it plays nicely with AUTOLOAD. I fear I'm gonna have to tackle that precomp issue soon. 20:22
MasterDuke are these bugs in rakudo you're finding? or I::P5?
nine I::P5
A couple rakudo bugs along the way ;) 20:23
jnthn MasterDuke: Not looked at the patch, but could it be it's writing the string heap and/or its length before adding the hll string? 20:32
nine Once someone's said it, it's so god damn obvious 20:33
MasterDuke ha!
nine And he not even looked at the code :)
MasterDuke and i've even been playing around with that $hll a bunch and didn't think of that
jnthn hah, that's what it was? 20:34
nine jnthn: you know, you could have pretended that it was any challenge at all for you
MasterDuke i'm testing now
the files aren't bit-identical, but the nqp build finishes 20:38
i.e., the *.moarvm in gen/moar/stage2 when built with current HEAD vs the previous commit on this branch that goes back and fixes up header values after the fact 20:39
nine where are the differences? 20:40

nine cool :)

i'm about to force push the newly rebased commit, but i guess it's still up for discussion whether it's a change that's desired at all 20:43
push to the PR
patrickb Are there separate makefiles generated in rakudo for the different backends? I'm wondering because all tools/templates/{moar,js,jvm}/Makefile.in include Makefile-backend-common.in 20:46
MasterDuke ok, github.com/Raku/nqp/pull/612 is updated. the first three commits (but really the majority of the change is in the second commit) write (some of the larger pieces of) the bytecode on the fly, but has to go back and correct the header. the fourth commit changes to write the header at the end 20:49
if the end state (some bytecode written on the fly) is in fact desired, i can always rebase/remove whichever other implementation isn't picked 20:50
uhh. t/qast/01-qast.t has a bunch of fails if i `make m-test`, but passes if i do `make t/qast/01-qast.t`, but then has fails again if i `./nqp-m t/qast/01-qast.t` 20:59
