samcv hello all 01:53
yoleaux2 00:05Z <AlexDaniel> samcv: if I'm getting ā€œshould eventually be unreachableā€ thingy in my code, what does it mean?
samcv AlexDaniel, it means you need to update
unless you are already updated. in which case. please let me know. but it shouldn't happen anymore 01:54
AlexDaniel This is Rakudo version 2017.03-28-ga01d6794d built on MoarVM version 2017.03-22-ga00278e6
samcv also it means "something in MVM tried to get a property value for a codepoint less than 0"
but whoever wrote the error wrote some generic thing
AlexDaniel samcv: is that updated enough? ā†‘ 01:55
samcv it should be. uhm
AlexDaniel yea, that's what I thought too
samcv hold on AlexDaniel
AlexDaniel, run this, and tell me if it passes or not gist.github.com/samcv/0df9fcc0c119...fbee6f24d7 01:56
AlexDaniel samcv: it does 01:57
samcv if that passes and you still get that error. show me the code that makes it happen, would be great
AlexDaniel samcv: mmmhmm it's this: github.com/perl6/whateverable/blob...#L127-L131 01:58
I wonder if just adding XĶ«āƒ to file you gave me is going to make it fail
samcv so if i dl it and run the test then it will show that error?
great :)
adding what?
AlexDaniel ā€¦ no, that's not going to run that simply 01:59
samcv oh
can you golf it into something i can test myself?
or is that infeasable 02:00
AlexDaniel well, it's something about XĶ«āƒ
I can do that
samcv yay
also AlexDaniel are you on windows 02:01
AlexDaniel no, that test fails on the server (linux)
samcv kk
ok so no \r\n line endings, probably

AlexDaniel ā€œcase insensitive string compare fixā€ :)
samcv well it did fix a way worse bug
which could affect every character
not matching if there were things that got longer on casefolding it'd be off
AlexDaniel well, I'm happy that I have a bunch of whateverable tests :) 02:10
samcv hmm i wonder if anything changes length on lowercasing
and nobody ever noticed that bug so far, cause it's always been there

AlexDaniel oh
samcv: want me to file a ticket for that?

samcv yeah trying to get the property value of -2 02:22
for the case folding property. ah. ok makes way more sense 02:23
ok i think i've almost fixed it 02:32
yeah i fixed it. just gotta run spectest
good find AlexDaniel++ 02:34
very happy you found that

well it works. this error is mostly harmless but maybe it was giving that warning before 03:12
at least on clang
oh it's new, but because the new function i have to use for synthetics doesn't have const. so that's fine 03:13
copying and pasting it is messing up this thing. AlexDaniel if i send you a patch can you reinstall mvm and test? 03:17

well at least it's not a new bug
or maybe that's bad. but at least it means it's not my fault ;)
geekosaur null regex rejected is avoiding another perl5 trap
samcv yes 03:23
ok well this works AlexDaniel. can you compile mvm if i commit and test. idk how your selver is setup 03:24

Fix case insensitive string compare bug when synthetics in haystack

If we have a synthetic in the haystack, we have to do more work and use the MVM_nfg_get_case_change function which will properly work with synthetics.
This fixes a bug that would cause error "should eventually be unreachable" on doing case insensitive regex or other case insensitive ops.		 03:28
AlexDaniel bisect: old=XĶ«āƒ say 42 03:36
ahā€¦
rightā€¦ 03:37
I always forget that this happens
samcv what happens? 03:53
oh. it messed it all up
AlexDaniel samcv: all unicodable tests are OK
that's all I can say :)
samcv yey
would you be able to add some tests to roast for me 03:54
or should i do it. idk maybe you have a good assortion of random unicode junk to use
AlexDaniel samcv: I'm trying to go to bed for the last 2 hoursā€¦ :)
so would be nice if you did it
samcv ok :)
i can do it later then 03:55
AlexDaniel and no, I don't have unicode junk :(
samcv i will have to aquire some random unicode text
AlexDaniel but now I wonderā€¦ there are some crazy unicode files on the internet built exactly for this purpose
samcv idk i need some like text files that are all in different languages
tbh
but project gutenburg is only in english and other noncrazy languages
yeah there are AlexDaniel. 03:56
they are hard to copy and paste though :P
more just complicated real world things. i have sources of weird unicode that is horrible and looks crazy. but want things in multitude of scripts and such 03:57
maybe use wikipedia and copy some common pages that have articles in all languages ever
AlexDaniel or maybe some random testing can help? 03:58
samcv well yeah. but i need a bunch of sources first
so ideally i'll get text files of every script and can run the same tests on each one 03:59
similar to gist.github.com/samcv/0df9fcc0c119...fbee6f24d7
but also for things like regex and other things
AlexDaniel oh right
samcv also i think most of those hangul are already in NFC form
so ideally would want to make it in NFC/NFD inconsistently and there's many things 04:00

timotimo so what do i do to check out exprjit stuff with c calls? :3 09:18
brrt you check out even-moar-jit, compile and run the following gist 09:20
samcv hey brrt 09:21
brrt gist.github.com/bdw/bcbe317c1f4753...ac8e56b68f
hey samcv, timotimo
that will compile a call to 'say'
it won't use the value, though 09:22
there's a bunch of things i haven't done to get to 'production quality'
but, it will compile, spill, order arguments, invoke and reload 09:23
and i think that's pretty neat, tbh
timotimo "use the value"?
brrt i can't guarantee any of the topological sort stuff works well either, because, well, it hasn't been used yet
return value of any C function, i mean
timotimo ah, ok
that shouldn't be terribly bad? 09:24
brrt to do? no, but, %rax is now my spare register, so i need to insert a move to an allocated register
that wants some additional logic
timotimo do we still have an env var to turn exprjit on? 09:27
brrt no, it's on by default
you have to turn it off
timotimo when it encounters stuff that requires c call return values, will it just refuse to jit that part, or will it get a bogus result? 09:28
hm 09:29
but if i can compile that gist, that means it gets through the compiler
brrt there are no templates defined that have c call return values, yet 09:39
i need to update the plan.org file to take that into account
timotimo cool 09:40

samcv good *
Zoffix \o 21:41
jnthn That would make sense for ==> and friends, which we're defining (I think :)) in terms of a set of blocking producer/consumer
But not so much for .hyper/.race where there's no point having blocked threads (aside from the one working sequentially) around, when we can instead just not schedule stuff to be done until we're ready
lizmat: ^^
o/ samcv
samcv good morning
samcv yawns 21:42
lizmat jnthn: I guess my point was that nqp::push on a ConcBlockingQueue should to the scheduling bits
so it wouldn't block the thread, just like sleep doesn't anymore in 6.d
jnthn Ah 21:43
No, I don't think that's a good way to do it
sleep *does* block the thread in 6.d 21:44
It's await that is non-blocking
(await Promise.in(5) or so)
lizmat well, we could have sleep do: $*THREAD > 1 ?? await !! nqp::sleep :-) 21:45
jnthn Grr, the naming of those Internal classes is using Hyper to mean "this whole framework of things" in a bunch of places 21:47
That are applicable to hyper and race
lizmat yeah, stuff is hard :-) 21:48
jnthn Aye 21:49
Details aside, does the general idea of desugaring to a fork/join graph make sense to you?
So far as I can see, it's a general enough model for all the things we'd need 21:50
MasterDuke jnthn: any further thoughts/comments on github.com/MoarVM/MoarVM/pull/557 (native overflow detection)? 21:52
yoleaux2 10:01Z <dogbert17_> MasterDuke: I'm not getting any SIGABORTS in t/spec/S17-supply/supplier-preserving.t. You haven't forgotten to turn off --full-cleanup by any chance?
lizmat jnthn: yeah it does
for a moment I thought the HyperBatcher would need rotor semantics
but that should probably be done serially before HyperBatching 21:53
jnthn Yeah, I'd kinda concluded that all but the simplest cases of rotor would need to do that
That's probably fine, since a rotor feels like someting you're more likely to do at the start or end of an operation, not in the middle, most of the time 21:54
At the end of the day, part of effective use of .hyper and .race will be understanding that you need to write pipelines that cooperate with them :) 21:55
lizmat indeed 21:58
and wrt to unique passing the seen hashes, just passing the necessary meta information as the first element in the HyperWorkBatch would work fine more generally as well I would think
jnthn I'd prefer to pass it out-of-band in the .extra slot 21:59
Just feels a bit cleaner 22:00
We'll need to be really careful on thread safely of that thing
lizmat well, the processor is done with the seen hash at that point, so there would be no harm having another thread having a go at it, would it ? 22:01
as long as it is a single one ?
jnthn Yeah, going from the many-batches one to to the joined one is pretty safe 22:02
MasterDuke: Left comments 22:05
MasterDuke cool, thanks
jnthn If you'd rather to the split as a follow-up PR I can go with that 22:06
It feels like the right thing to do.
(splitting them, that is...I've a slight preference for doing it as part of this PR) 22:07
MasterDuke i replied, i think the split requires a lot of other work done also, it's not just changing the calls to mp_get_int64 in P6bigint.c 22:10
the attempt to split them in fact it what led me down the path of trying to add *_u ops 22:11
jnthn I just meant splitting that one function, rather than passing is_signed and doing conditionals 22:17
MasterDuke yeah, that's what i tried 22:18
jnthn Sure, but everything that's calling it now is either passing 1 or 0 for is_signed?
I'm not saying all the callers have to call the one they ultimately should 22:19
MasterDuke let me try splitting it again, it's a quick change, maybe i got mixed up while also doing that other PR 22:20
jnthn MasterDuke++ 22:23
MasterDuke arg (and yay)!! that worked 22:33
jnthn One less arg ;) 22:37
