japhb Wait, what about --target=mast ...? 00:00
timotimo you're looking for ways to inspect generated bytecode? 00:01
ShimmerFairy timotimo: just wondering if literals in things like nqp::add_i(42, 0) are treated as native ints (for example) without having boxing/unboxing going on
timotimo yeah, ought to
japhb timotimo: Err, what ShimmerFairy just said
timotimo: Yes, but are they *actually* 00:02
--target=mast is HUGE for such a simple thing
ShimmerFairy japhb: just realized I did --target=optimize without specifying an optimize flag, hang on :P
00:02 FROGGS joined
timotimo 00018 const_i64_16 loc_3_int, 52 00:03
00019 const_i64_16 loc_4_int, 0
00020 add_i loc_4_int, loc_3_int, loc_4_int
that's the interesting part for "use nqp; nqp::add_i(52, 0)"
with --target=mbc --output=test.moar and then moar --dump test.moar
japhb OK, so it *is* doing the right thing then.
ShimmerFairy timotimo: I still see Want ( WVal(Int), Ii, IVal(42) ) [abbreviating the output here to one-line of course] in --target=optimize
timotimo sure 00:04
00:04 dha left
timotimo Want is there for our lower code-gen to have a way of using a native value if it can 00:04
and otherwise it'll have a boxed object ready to go
another place where Want pops up is when we have code generated for void and result-expected cases of code
ShimmerFairy timotimo: ah, so it's me misunderstanding the IVal then :P (I though it was any kind of integer, not only natives) 00:05
timotimo that's the Want nodes where the value in the middle is "v"
IVal is actually a lowest-level-possible integer
ShimmerFairy I have noticed the sink context Wants before, yes :)
timotimo i don't think we can have IVal for bigints
ah, watch out, though; "sink" context as rakudo knows it is a little bit different, too 00:06
that's where all the "if can sink, callmethod sink" code comes from
00:06 perlawhirl joined
ShimmerFairy japhb: so, don't mind me, literals do get handled correctly after all :P Maybe the fact that your code was written pre-NFG has something to do with it? (Maaaaaybe? I doubt that could affect much though) 00:07
timotimo the WVal(Int) you see as the first entry to the Want is a boxed Int with (hopefully) the same value that's been put into the serialized blob
ShimmerFairy timotimo: is a Want useful with just one thing inside? (I'm guessing no.) And I don't suppose there's a way to have Wants for types in general. 'IntStr' and friends are interesting to think about; should they get a three-part Want? :P 00:09
timotimo oof.
a whole bunch of code will want (haha) to get adapted to that 00:10
at least some code i wrote has assumed that a Want has only two options (and the flag in between)
ShimmerFairy timotimo: I'm just trying to deal with calling &val at compile-time and doing $*W.add_object and stuff afterwards. I have a QAST::WVal(:value($thing)) after add_object, but it'd be nice to wrap that in a Want methinks (but how does an allomorphic type go in a Want? O_o) 00:11

timotimo what do you mean "how does it go in a want"? 00:35
i'd imagine it'd be like Want(WVal(IntStr), "Ss", SVal("123"), "Ii", IVal(123)) 00:36
timotimo ought to go to bed soon
00:38 rangerprice left 00:40 ktv joined, laouji joined 00:43 ktv left 00:44 laouji left, laouji joined
ShimmerFairy timotimo: OK, I'll try that if needed. Right now I've got a weird problem with the is trait_mod and having a Want(WVal(Str)) come out of using &val (hopefully substituting a 'failed' val call with the original QAST fixes it) 00:45
I read in the QAST doc that Want() shouldn't be used for combining a string and int in one thing, because it could cause ambiguity issues, but that's what the allomorphic types are all about :P 00:46

Fudged tests of numifying certain 'slash fractionals'

These tests all make sure that you can't numify slash fractional strings with negative denominators and/or non-integral components. Since it's unclear what val()'s stance should be on these things.
The S02 tests are fudged because val processing takes over on a failed Rat literal, and produces a RatStr as it stands. It's not specified if this is expected, or if Rat/Complex literals are meant to be all-or-nothing.		 05:05

nine jnthn: should gather blocks always be marked lazy? Just because we might have a gather { take $_ for 1 .. Inf; }; Or do we leave it up to the user to mark it as lazy? 08:59
jnthn nine: Interesting question. Not easy to call what the best default is. If we make it lazy by default we force people to mark "eager". 09:04
nine: If we make it eager by default then we can get hangs.

FROGGS skaji: CompUnit knows about what got loaded, though it is not exposed (yet) 10:51
skaji is it intended to be exposed? 10:53
timotimo it surely would be useful in some situations
skaji i need %INC or similar, because i often have the same module in several libs.
FROGGS skaji: I don't know... I think we can expose it, CompUnit itself is meant to be not just something internally 10:54
timotimo you can introspect GLOBAL:: to see what modules have been imported to the global namespace 10:55
m: { use Test }; say GLOBAL::.keys
camelia rakudo-moar 149b5f: OUTPUT«(Test)␤»
timotimo ^- here you can see, that Test is still available through GLOBAL 10:56
FROGGS you see symbols, not modules though
if you load a .pm that does not export a symbol, you won't see it in GLOBAL
timotimo oh 10:57
that's right
10:57 pmurias left
FROGGS and CompUnit is about a .pm file, which can export several symbols, or none 10:57
skaji i hope CompUnit is exposed!

FROGGS skaji: that's what you are interested in: github.com/rakudo/rakudo/blob/nom/...nit.pm#L15
psch skaji: i imagine your use-case is something like "i need .pm files in different directories for different projects that have to package them but don't want to change my @*INC for every project"?

timotimo jnthn: i wonder how hard it'd be to make CArray multi-dim compatible, too ... and if we should keep CArray for int/num around at all, now that Buf and Blob should be able to handle those cases just fine? 11:58
FROGGS timotimo: CArray needs to stay because if a C-functions returns something array-ish, you can only return a CArray 11:59
to return a Buf you'd need to know the size 12:00
timotimo oh? 12:02
huh, so if something returns a CArray and you know the size, you can just safely access all elements up to that size? 12:03
FROGGS timotimo: well, in case the C-function does not lie, yes 12:04
timotimo cool, abraxa may be happy to hear about this 12:05
FROGGS hmmm?
he knows
timotimo oh
why didn't i know, then? :P
12:05 yqt joined
FROGGS he calls the oci function and gets a bufferish thing and the 'length' back, then he slices length-1 elems out of that buffer 12:06
so he already trusts that length
12:06 CIAvash left
timotimo OK 12:07
12:09 aindilis joined
FROGGS though is would be nice to have: my $buf8 = nativecast(buf8, $buffer, :$elems) as a cheap shortcut to the loops 12:15
or slices
12:15 ambs joined
timotimo yeah 12:16
with a memcpy in the back-end
12:16 rurban joined
jnthn FROGGS: I've been thinking about a memcpy style op in Moar, but didn't have the brane to work out exactly how I want it to function yet :) 12:16
timotimo hm, say 12:17
can't we actually just pass a Buf to a native sub? 12:18
in that case we could actually just use regular memcpy
TimToady awake at 5am, not surprisingly...
timotimo mhm, all the travels 12:19

MODULE_DEBUG: loading /Users/skaji/env/rakudobrew/moar-nom/install/share/perl6/lib/Test.pm.moarvm
FROGGS skaji: that path is the key in %instances btw 12:21
jnthn: yeah, though however it is implemented I think the code I posted could very well be the way we expose it 12:22
though we should rename this bloody sub
12:30 xinming_ joined
jnthn cast is misleading as it tends to just mean a change of interpretation rather than a copy 12:30
timotimo right 12:31
FROGGS hmmm 12:32
skaji FROGGS: I see
FROGGS do we have to copy at all?
timotimo depends on what the C side of things thinks about ownership of the block of data 12:33
if we just blindly cast to a Buf, moar will end up calling free() on it
when the Buf gets collected
arnsholt If it's going to be put into a properly Perl 6 thing like a Buf, it should definitely be copied
12:33 xinming left
FROGGS what if you want to modify the foreign memory? 12:34

timotimo hm, you may be interested in ops that work on bufs, that's right 12:42
i gave CArray an elems method
perhaps it'd be enough to mix in a role that gives a "fake" length for that
and then you can use any subs that require a Positional? 12:43
FROGGS how does that elems method work?
timotimo it uses nqp::elems
FROGGS but how does it know the elems?
timotimo now that i've learned how CArray is supposed to work with "foreign" data blobs, it doesn't make quite as much sense
it's for cases where perl6 manages the memory
m: use NativeCall; my $buf = CArray[int8].new(1, 2, 3, 4, 5); say $buf.elems; $buf[20] = 1; say $buf.elems; 12:44
camelia rakudo-moar ae6510: OUTPUT«5␤21␤»
12:44 ambs joined
timotimo how do we differentiate between "when we assign to a high index we should realloc" and "when we assign to a high index we should directly access memory there"? 12:44
FROGGS so it would most like return 0 if it is the return value of a C function
timotimo most likely, yes 12:45
in that case .gist and .perl won't work "properly", either
FROGGS I guess that depends on who created it
timotimo well, you can't set the elems of a CArray with the regular setposelems operation
because CArray doesn't implement that
FROGGS MVMCArrayBody has a "managed" attribute 12:46
a bool 12:47
timotimo ah, it's that easy!
neat.
maybe i should implement setelemspos (or however that's called) on its REPR and if it's managed, it'll be reallocd and if not, it'll just set the internal counter for the number of elems
FROGGS and it allocates 4 slots by default, but counts the "used" slots 12:48
sounds good to me
timotimo then you can grab a CArray, set its size (because you know it) and use its .list and .gist and such
FROGGS hmmm
that sounds awesoem
arnsholt Speaking of CArray reallocing when it's allocated from Perl 6, that functionality should probably be removed
FROGGS awesome*
timotimo are you sure? 12:49
i can see how accidentally reallocing after passing to c functions could be dangerous
arnsholt Because if C code stores the pointer to a Perl 6 allocated CArray somewhere, and it's then realloced, things are gonna break horribly
timotimo but we expect the user to know a bit about how memory management works
arnsholt And it'll probably be weird non-deterministic breakage, because sometimes realloc can return the same pointer, and sometimes not 12:50
Depending on what's free
It's a nice feature, but ultimately I think it'll end up causing unnecessary grief
12:50 pecastro joined
timotimo if CArray doesn't realloc on access, we need a way to create it with a fixed size 12:54
otherwise we can't use CArray from perl6 at all
arnsholt Yeah, definitely
timotimo then people will have to create their data in arrays and turn them into CArray at the latest possible moment 12:55
12:55 telex left
arnsholt Yeah, if you can't precompute the size, then you'll have to do something like that 12:56

timotimo if not, you can nqp::say(...) 13:28
abraxxa i had one after the $ex line which it didn't like
timotimo oh 13:29
abraxxa can it use more than one core to compile?
timotimo perhaps Expression.pm is actually that early inside the core setting
sadly not
abraxxa this line causes it: nqp::rethrow(nqp::getattr(nqp::decont($!), Exception, '$!ex'));
the second to last one
timotimo ok, so $! is probably not set properly? 13:30
as in, is not an instance of Exception

ShimmerFairy [Coke]: what's so wrong with that? I wasn't sure how rebasing would affect my merging work, since it moves history around, so I chose the safer route. 14:17
[Coke] It makes it harder for me to review what was done, for one. 14:18
that's been the convention, also, so far as I know. happy for one of the long time contributers who is also a git person to chime in. 14:19
ShimmerFairy Like I said, I was unsure how much worse rebasing would screw with the history (I know it doesn't update timestamps in commits it moves, at least), and considering I had to start this merge with a revert of a revert of a merge, I wasn't inclined to risk more strife :) 14:20
14:20 aborazmeh left
[Coke] ok. I hope someone else is reviewing your commits here. 14:21

FROGGS jnthn: do you have any idea why I can get this? Method 'collisions' not found for invocant of class 'NQPClassHOW'
NQPClassHOW basically does NQPConcreteRoleHOW, which has that method
jnthn FROGGS: There's some poor error reporting sometimes when things go wrong with roles

jnthn nine: Yeah, figured I'd work on some of those
FROGGS abraxxa: so your paste about int and real look good, the Str candidate not so
timotimo when my @a = 'foo' xx 1000 gets faster, we'll beat a benchmark where post-glr is pretty bad compared to pre-glr 15:41

[Tux] nine, I don't see your change other than the hint to make gather default to lazy, which I think is correct 17:09
dalek kudo/nom: 5b659cc | jnthn++ | src/Perl6/Actions.nqp:
Loops no longer need sinking.

They no longer evaluate to anything (and when they will start to, it they will be lazy).		 17:10

Cheaper way of avoiding sinking.

jnthn |Tux|: Well, only the one I said really...

[Tux] what it does is split the string into "chunks" 17:12

abraxxa FROGGS: how can i reserve memory for $valuep[0] = Pointer[Str].new; ?
masak dha: no, it's quite explainable.
dha Oh, I'm sure it's explainable. :-) 17:23
masak dha: in the first eval, `$` is a new `state` variable. (you can't refer to a `$` after you declared it; they're once-only)
[Tux] Inline::Perl5 also fails:
Ambiguous call to 'p6_to_p5'; these signatures all match:
:(Inline::Perl5 $: Int:D $value, *%_ --> Pointer)
:(Inline::Perl5 $: Str:D $value, *%_ --> Pointer)
masak dha: in the second eval, `$.perl` means `self.perl`, but you're not in a method.
dha: your original mistake seems to be to assume that you can refer back to a declared `$` -- but that's exactly what you can't do with them, since they aren't even installed in the lexpad. 17:24
dha: and all your attempts to access it ended up meaning something else :)

masak dha: no, I'm not saying that. I'm saying that if your declaration is `my $`, then that `$` is nowhere to be found. (and it has nothing to do with `state` variables.) 17:29
dha Isn't C<$> the anonymous state variable?
masak dha: specifically, what you're doing is not "'my'-ing a state variable".
dha: not in a `my` declaration, it isn't.
dha: there it's just a "don't assign anything here" placeholder. 17:30

camelia rakudo-moar d260bd: OUTPUT«3␤»
dha Hm. that seems confusing to me.
17:30 n0tjack left
masak that's the original use of `$`. 17:30
the `$` meaning `(state $)` came much, much later.
dha That doesn't make it less confusing. :-) 17:31
Also, I'm getting the same error without the "my". So maybe I'm totally confused. Which is entirely possible.
masak you can't refer to a state `$` either! why do you keep expecting to? :) 17:32
look, they're *anonymous* variables!
they don't have a name. they don't have an entry in the lexpad.
dha Great. So what are they for? 17:33
masak one-time use.
m: sub foo { say ++$ }; say foo() for ^6

masak m: sub foo { say ++$ }; foo() for ^6
camelia rakudo-moar d260bd: OUTPUT«1␤2␤3␤4␤5␤6␤»
masak the thing with `state` variables is that they stick around. so referring to them just once in a program makes sense sometimes.
the use of `my $` I demonstrated above with `my ($a, $, $c) = 1, 2, 3;` -- basically, skipping over rhs values. 17:34

FROGGS :S 20:52
abraxxa you need to allocate a statement handle and define the number of bytes all string binds will take plus 2 bytes per string for \n\0
then you get back a pointer to that memory location which you have to divide for each string you'll pass
job = (text *) (ename+enamelen+2); 20:53
that's the example code
ename is the pointer you get back from the OCIHandleAlloc call, job is the pointer to the memory location in the middle of it where the job string will start
abraxxa HATES C
grondilu wonders what gmr is 20:54
abraxxa so how do I get a pointer to a memory location inside a Pointer?
FROGGS grondilu: Great Map Refactor
grondilu ok
abraxxa Google Maps Refactor?
FROGGS abraxxa: :D 20:55
grondilu now I wonder if that will solve the need to add a few 'flat' in the digest codes after GLR
abraxxa the OCI library is way too low level
FROGGS abraxxa: that's how these libs are... sadly
grondilu (because a few of these flat were just before a map, precisely) 20:56
FROGGS grondilu: no, it is about hashes... it removes EnumMap and stuff

there is another deref method

psch (irclog.perlgeek.de/perl6/2015-08-14#i_11055681 has a description of my debuggin process, btw)
FROGGS psch: look at that: github.com/rakudo/rakudo/blob/nom/...va#L77-L79
this is pre glr: github.com/rakudo/rakudo/blob/pre-...re/List.pm 21:52

err, this for pre-glr: github.com/rakudo/rakudo/blob/nom/...ist.pm#L74 21:53
so there are outdated hints in there
abraxxa FROGGS: but why does this fail then? my Str $col_name = $col_namepp[0].defref;
FROGGS and probably code that does not know about the new semantics
abraxxa Method 'defref' not found for invocant of class 'Pointer'
psch FROGGS: pre-glr is lines 40-44 i think?
FROGGS abraxxa: it is called 'derefÄ

FROGGS no
abraxxa from /home/abraxxa/perl6/git/DBIish/lib/DBDish/Oracle.pm6:666

FROGGS abraxxa: yes, that's what I would expect
dalek Heuristic branch merge: pushed 32 commits to rakudo/cu_load by lizmat
abraxxa FROGGS: why? 22:09
psch hrm, idea didn't work out /o\
FROGGS abraxxa: because then the pointer is typed, so it works
psch: :/
abraxxa FROGGS: i call deref on the Pointer object (instance) which is typed as Str
FROGGS: i mean why the second case fails
psch in any case, the SOE happens because of 101 calls to foreign_array_transform, and iiuc about 50 of those originate from one hllize call 22:10
well, i suppose all 101 calls aren't to blame, just the ~50 in a row
lizmat is very tired and goes to bed...
FROGGS abraxxa: because the array has a different type, and so does the slot I guess
psch as an aside, the stacktrace from catching the SOE is ~8100 levels deep...

i had pulled the flat hllize statement apart
but i assigned the hllize result to an (p6-level) @-sigiled array 22:13
ugh, still not quite clear on those semantics
22:13 abraxxa left
psch m: say flat (1, (2, 3)); say my @ = flat (1, (2, 3)) 22:13

camelia rakudo-moar 079d73: OUTPUT«(1 2 3)␤(1 (2 3))␤»
psch that works on (the half-finished) jvm build as well 22:15
and pulled apart it's the hllize call that goes off the deep end
so i'm trying to assign to something sigilless now and see what ends up in there hah
...that passes Pod::To::Text 22:18
so hllize "into array context" is somehow borked 22:19
which still points at foreign_array_transform, i suppose...
FROGGS so your modification has the same affect as:
- for flat nqp::hllize(@*PACKAGES) {
+ for |nqp::hllize(@*PACKAGES) {
hmmm, perhaps it calls the wrong flat candidate?
ohh, there is just one -.- 22:20
22:25 Sgeo left
psch yeah... and that candidate effectively defers to the Binder... >_> 22:25
FROGGS aye
psch - for flat nqp::hllize(@*PACKAGES) {
+ my \pkgs := nqp::hllize(pkgs); # ...wat 22:26
+ for flat pkgs {
is my patch
(minus lots of other debug says...)
one thing i'd like to check but haven't figured out how 22:27
is if NQPArray plays in there
'cause i can't find a way to create those in the perl6 runtime
FROGGS btw, @*PACKAGES is not declared anyway I think
psch @*PACKAGES comes from World or Grammar iirc
yeah, Perl6/Grammar.nqp 22:29
it holds the name of the package the "is export" symbol belongs to
and that's in there, too, i was able to verify that 22:30
FROGGS hmm, interesting
psch and that's probably why it's an NQPArray, and neither an Array not a BOOTArray
FROGGS yes, most likely

Juerd Thanks! 23:02
psch if you know $bar to be undefined you don't need the .WHAT 23:03
Juerd It won't be undefined 23:04
ugexe also the uglier `$z.isa($bar.^name)` 23:10
(in reference to the complaints from hn or reddit the other day over `.METHODS`) 23:13

23:15 spider-mario left
psch i had thought that might've been the reason for the discrepancy between .isa(*.^name) and ~~ *.WHAT one eval higher... 23:15
but it's probably just the subset 23:16
i'm guessing they automagic an .ACCEPTS that takes the where clause into account, but the bare literal of course stays a Str...

ugexe ah. how about $z ~~ ::($bar.^name)?
timotimo that'? a lot better 23:34
.isa will go through the mro and compare all the names, or something like that
there was some kind of benchmark a couple of months ago (slightly similar to excel formulas) which had .isa("Foo") in it and changing that to a ~~ gave a ridiculous speed boost
