nine releasable6: statisfiable6: 08:42
releasable6 nine, I cannot recognize this command. See wiki for some examples: github.com/Raku/whateverable/wiki/Releasable
nine releasable6: status
releasable6 nine, Next release in ≈19 days and ≈10 hours. There are no known blockers. Changelog for this release was not started yet
nine, Details: gist.github.com/f574a1b543f8a8bf95...886b0e39e2
Geth MoarVM/master: 4 commits pushed by (Stefan Seifert)++, niner++ 08:43
Nicholas good *, * 08:50
Geth MoarVM: a3476e2869 | (Stefan Seifert)++ | 2 files
Turn on C11 atomics by default

It's been a while since these were enabled optionally and I've been using them for almost as long without any fault whatsoever. It's time we give them some more exposure.
Nicholas oh, "may you live in interesting times"
nine Well, Linux distros will like this as it gets us rid of one more bundled dependency 08:59
The packages for openSUSE Tumbleweed already build with --has-libffi --has-libtommath --has-libuv and work just fine. 09:00

lizmat nine: compilation seems slower since I bumped MoarVM... should it ? 11:44
nine No. How much slower? 11:46
lizmat finger in the air: up to 5% ? 11:51

nine That would be ~ 1s for core.c parsing. Sounds like that's within noise 12:09
12:17 dogbert11 left
lizmat I also see it in spectest timing 12:17
afk for a few hours& 12:20
in any case, it shouldn't be slower, right ? 12:22
ugexe well doing .mkdir is twice as slow than .e for the common case, and now that is happening during every path object creation 12:27
moon-child users.cs.northwestern.edu/~robby/c...g-data.pdf
ugexe ...in CUR. which is still a lot 12:28
[Coke] would it work to re-add the "once"? 12:29
and then still not bother calling .e then?
jnthnwrthngtn nine: Nice work on the package vars; left a couple of comments on the commit, but also t/12-rakuast/package.t has regressed, also spectest lost 28 fully passing test files. 12:32
(The latter by `make spectest` and then `RAKUDO_RAKUAST=1 make spectest | grep '\. ok' | wc -l`, which was 320 before and now 292 12:33

nine I'll try to get those declarations to work without making the Package do LexicalScope 12:38
It's kinda funny that packages and $?PACKAGE specifically are often used as examples in comments, when they were not actually implemented :) 12:40
13:11 sena_kun left
jnthnwrthngtn Well, `$?PACKAGE` was already bound to GLOBAL in RakuAST::CompUnit, I believe 13:13
But yeah, any kind of nested package stuff hasn't really been done yet
Well, it's getting done now thanks to you :) 13:14
13:15 sena_kun joined
nine This stuff is complicated... Replacing PRODUCE-IMPLICIT-DECLARATIONS and direct QAST manipulation with an apply-implicit-block-semantics that calls $!body.add-generated-lexical-declaration, we get correct runtime behaviour, but at compile time it doesn't find the package's $?PACKAGE 13:47
14:24 ggoebel left
nine Ah, I'm actually so close... problem is just that QAST::Var(lexical $?PACKAGE :decl(static)) is generated right after the QAST::Op(bind) that looks up $?PACKAGE 14:34
And now its working :) 14:48
jnthnwrthngtn: I wonder: do we actually need to lookup $?PACKAGE for initializing package scoped variables? It's used for $bar := $?PACKAGE.AT-KEY('$bar'). Seems to work just fine when I use a WVal for the meta-object and I guess that would be a little bit faster? 14:50
lizmat ugexe: good catch 15:01
TIL nqp::mkdir is pretty expensive
15:04 frost left
ugexe src\moar.h(44): fatal error C1083: Cannot open include file: 'stdatomic.h': No such file or directory 16:13
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30133\bin\HostX64\x64\cl.EXE"' : return code '0x2'
Stop. 16:14
16:24 sena_kun left
jnthnwrthngtn nine: I think the WVal approach should work 16:26
16:30 sena_kun joined
nine done :) 16:33

nine Would be so nice to just be able to use note(...) for debug output in the nodes 18:30
lizmat what can't you ? 18:34
nine They're part of the bootstrap. No settings available yet and NQP's setting is not in scope either 18:39
lizmat hmmm 18:41
19:09 sena_kun left
nine Apparently I have a nack for breaking things. My "less hacky" commit broke class Foo { method foo() { 456 } }; which now gives "Package 'Foo' already has a method 'foo'". No idea how though. 19:18
Looks like the parser attaches the method multiple times which means that it will be added to the package multiple times. 19:19
lizmat existence check always returning true ?
ah... yes, that would do it
nine Removing "is RakuAST::ImplicitBlockSemanticsProvider" from RakuAST::Package again unbreaks it. What the? 19:22
19:26 sena_kun joined
nine Aaah...it's the self.meta-object call in apply-implicit-block-semantics 19:35
Commit ae3b46ee51 fixes the package regression. 19:44
Doesn't fix all the spectests though :/ commit 023ec833f gives me 277 ok, HEAD^ gives 246 and HEAD is at 254 20:00
