Internal error: find_var_decl could not find $_
Kaiepi is this a bug or am i just doing something i'm really not supposed to be doing?
[Tux] just spotted yet another advantage of kebab-style: the '-' never disappears, where the '_' will disappear on *some* fonts* in *some* editors under *some* conditions 07:03
(I just had to use a graphic editor on some old linux box over ssh, with antialiassing and a weird font and I did not understand the code at all. All syntax errors to my eyes till I noticed that all '_' showed as spaces. 07:04

robertle_ after reading perl6.online/2019/06/24/102-insert...in-perl-6/ I am wondering what the time complexity of splice() itself is. I am experimenting, but am getting pretty erratic results, I guess optimization or so wreaks havoc on my tests. I guess it's going to be pretty linear with the size of the array in the general case? 08:52

Kaiepi the wrong dispatchee is indeed getting called
PseudoStash.EXISTS-KEY isn't a multi and has this comment: # for some reason we get a ambiguous dispatch error by making this a multi
should PseudoStash.WHICH also not be a multi or would it be a better idea to look deeper into why the error's happening with both these methods? 16:16

AlexDaniel kawaii: mm, the changelog needs some doing :) 19:00
timotimo dogbert17: yeah, that looks like it wants : there as well 19:02
and MaxHash, too, of course, but i'm sure you already saw that 19:07
lizmat m: dd <a b c>.Bag.BagHash 19:25
camelia ("a"=>1,"c"=>1,"b"=>1).BagHash
lizmat hmmm... how does that work then ?
I guess it took the Any.BagHash variant 19:26
timotimo m: say <a b c>.Bag.^lookup("BagHash").filename
camelia No such method 'filename' for invocant of type 'Method+{is-nodal}'
in block <unit> at <tmp> line 1
timotimo m: say <a b c>.Bag.^lookup("BagHash").file
camelia SETTING::src/core/Any.pm6
timotimo m: say <a b c>.Bag.^lookup("BagHash").line
camelia 454
lizmat yep, that's the one 19:27
dogbert17 dunno, but I'm no signature expert. I did get inspired by kaiepi++ PR above and started to look for suspects
timotimo oh, that's the proto
m: say <a b c>.Bag.^can("BagHash", \())
camelia Too many positionals passed; expected 3 arguments but got 4
in block <unit> at <tmp> line 1
timotimo m: say <a b c>.Bag.^cando("BagHash", \())
camelia No such method 'cando' for invocant of type 'Perl6::Metamodel::ClassHOW+{<anon>}+{<anon>}'. Did you mean 'can'?
in block <unit> at <tmp> line 1
timotimo how do you spell that again ...
lizmat dogbert17: already testing with 3 places fixed 19:28
dogbert17 did you make a fix in Set.pm6 as well?
Geth rakudo: 8969399b31 | (Elizabeth Mattijsen)++ | 2 files
Add a few missing colons, spotted by dogbert++

There were no issues because of this, as the Any variant did the right thing, albeit much less efficiently
lizmat dogbert17: where in Set ? 19:29
dogbert17 src/core/Set.pm6: multi method grabpairs(Set:D $count?) {
lizmat good catch!
dogbert17 that's all I found but my search was a bit sloppy so there might possibly be more 19:30
lizmat m: say <a b c>.Set.grabpairs
camelia Parameter '$count' of routine 'grabpairs' must be an object instance of type 'Set', not a type object of type 'Set'. Did you forget a '.new'?
in block <unit> at <tmp> line 1
lizmat it dies, which it should :-) 19:31
$ 6 'say <a b c>.Set.grabpairs' 19:32
Cannot call 'grabpairs' on an immutable 'Set'
but that is better ^^ :-)
dogbert17 Iaha
*aha
Geth rakudo: 9b639961c0 | (Elizabeth Mattijsen)++ | src/core/Set.pm6
Another missing colon, spotted by dogbert++
 19:33
dogbert17 perhaps AlexDaniel has a bot which can check the Rakudop codebase :)
AlexDaniel not yet :) 19:34
dogbert17: git grep?
:)
dogbert17 I used normal grep which might not have been optimal 19:35
kawaii AlexDaniel: yes I noticed, pretty big gap so lots to do, probably make a start on that tomorrow with your guidance? Not 100% sure which commits deserve their own changelog entries and such - will need to run those by you
I gather that there is a tool which can do some of this work for me IIRC
AlexDaniel kawaii: I usually start by removing some junk ā€“ reverted commits, merge commits, other stuff 19:36
commits that touch comments only, whitespace, tests, etc.
then I move the stuff that needs to be changelogged into the categories 19:37
and finally I reword the commit messages so that they're consistent
usually all that is done in like 5 passes or soā€¦ I'm really slow at it
would've been easier if I was a native speaker :) 19:38
lizmat dogbert17: thanks for the spots! I haven't been able to spot any others 19:44
dogbert17 thanks for looking, perhaps we got all of them 19:45
lizmat hopefully, yes :-)
dogbert17 btw, is timotimo still lurking around :) 19:46
lizmat he said he was going to afk for a bit
Kaiepi m: say Mix.new('a' => 1).^lookup('MixHash').file 19:47
camelia SETTING::src/core/Any.pm6
Kaiepi another one
dogbert17 ah, I'll catch him a bit later then 19:49
lizmat Kaiepi: I think I just fixed that one 19:50
Kaiepi oh
i just ran egrep on src/core and am going through all the files for any missing colons 19:51
lizmat did you just do git pull ?
Kaiepi not since my commit was merged
lizmat then you should :-) 19:52
Kaiepi doesn't look like there's anything apart from that that's the same kind of error 19:56
there is this though 19:57

lizmat hhmmm
Kaiepi: if you're to add signatures / multis there, you should keep track that it doesn't affect performance too much :-) 20:00
Kaiepi m: use nqp; nqp::push(class A is repr('VMArray') {}, 1)
camelia (signal SEGV)
kawaii AlexDaniel: we should probably pick a commit to pin 2019.06 to then, as people will continue to commit well past us prepping the release
lizmat "This type is engineered for performance over friendliness, and should not be encountered in normal use of Perl 6. Do NOT add any checks and validation to methods in here. They need to remain trivially inlineable for performance reasons. 20:01
AlexDaniel you mean start a release branch
not really until most of the blockers are fixed
MasterDuke lizmat: hm, but maybe we can still prevent a segv? 20:02
Kaiepi how can i test the performance of iterationbuffer? if changing the signature reduces it, i could see if i could make a fix for nqp::push in moarvm 20:03
doubt there'd be much more to it than an IS_CONCRETE check or something along those lines 20:04
MasterDuke a backtrace of that segv if anyone is interested gist.github.com/MasterDuke17/6a369...e611286c1e
lizmat Kaiepi: whatever is done, I think jnthn would need to greenlight it
Kaiepi bastille% perl6 -Mnqp -e 'nqp::push(IterationBuffer, 1)' 20:08
MVMArray: push expected a concrete object with MVMArray representation
in block <unit> at -e line 1
yeah it's just an IS_CONCRETE check
lizmat Kaiepi: so how come it segfaults in Perl 6, but not in nqp ?
