sorear nice 01:55
total errors are down?
timotimo huh, rakudo is still regressing? 01:58
on parrot?
sorear timotimo: where? 02:04
timotimo in the last few days os cokes updates
github.com/coke/perl6-roast-data/b...pass_rates - used to be 26020 on the third entry, now it's still on only 25717
anyway, i should be going to bed 02:05
[Coke] ~.
timotimo: there's no failures on rakudo.parrot - possible tests were removed or something. 02:07
timotimo yes, i didn't see that. in the skip column there was a bump 02:09
sorear mostly just the "plan" column falling 02:10

JimmyZ hmm, when I typed nmake, I saw 'perl -MExtUtils::Command -e cp src/stage2/nqp.jar .' and similar things about 9 times once. 02:14

JimmyZ yes
and saw 'perl -MExtUtils::Command -e mkpath src/stage2/gen' many times 02:15

02:40 hypolin left, hypolin joined
sorear ManAmongHippos: No, we use a reference test suite instead 02:44
[Coke] I doubt there will anything called a reference implementation. There are multiple implementations in progress, with rakudo being the most complete. 02:45
sorear ManAmongHippos: see github.com/perl6/roast/

05:29 xilo left
moritz segomos: yes-ish 05:36
segomos with the mysql portion i'm preparing a simple insert stmt and getting 'Any' as the errstr being returned for the statement..not even sure where to start debugging - i looked at DBDish BUILD and didn't see much there to try 05:37
moritz segomos: so, no error occured? 05:38
segomos doesn't appear to have occurred but the statement doesn't execute
moritz have you set RaiseError? 05:39
segomos yes
moritz segomos: can you show me the code?
segomos no error is caught and (try CATCH) and the $! variable is empty
moritz (which all indicates that no error actually happened)
segomos yea let me throw it up on a gist
:q 05:40
hugme hugs segomos, good vi(m) user!
segomos lol, sorry - gist.github.com/tony-o/5898608 05:43
i have user/password/database set properly in the script where i can successfully prepare/execute SELECT statements 05:44
and the db user has full privs
moritz but the entry isn't written? 05:45
segomos correct 05:46
moritz that's very weird
because I know I've successfully inserted many rows with pretty much the same code 05:47
maybe something broke recently :/
segomos: if you set up the credentials correctly in t/25-mysql-common.t (in the DBIish repo), do the tests pass? 05:48
segomos moritz: i'll check it now 05:49

moritz 'cause when the tests pass, DBIish shouldn't be *that* busted that it doesn't even report an error 06:06
segomos yea - i think i have a problem with the way panda installed the lib. i'm getting kind of sleepy and fat fingering a bunch of stuff so i'm going to take a look in the morning but cloning your repo and running tests is passing and running the same tests against what's in my global @*INC is failing 06:07

rs0_ is there a direct perl6 equivalent of while (<>)? 06:31
lizmat $file.lines as .lines is lazy 06:32
06:33 salv0 joined
rs0_ well, while(<>) reads from either stdin or from files given as script arguments 06:33
i don't know if there's a similar shorthand in perl 6. some ancient web page i found claimed that for =<> is a direct equivalent, but that didn't compile 06:34
sorear $*ARGFILES is a magical filehandle with the same behavior
you can do for $*ARGILES.lines { }
just for lines() { } might also work 06:35
FROGGS it does

rs0_ interesting stuff 06:38
sorear there was a = prefix operator in ancient versions of p6, but it was ripped out before I joined the project 06:39
rs0_ oh, something else i was wondering about was whether there is a perl6 equivalent of Java's @Override annotation, such that you get a compile-time error if a corresponding method cannot be found in the class hierarchy
sorear no
rs0_ i think i saw in the logs that someone was looking at adding that feature but i'm pretty sure he was doing it on spec 06:40
sorear would be relatively easy to add as a module though, if anyone's interested
"on spec"?
rs0_ on spec, made, built, or done with hopes of but no assurance of payment or a sale; without commitment by a client or buyer: ad illustrations done on spec; luxury homes built on spec and sold before completion.

moritz is 'is default' even specced?
lizmat S02:653
jnthn And is it meant to bind or assign? 09:26
Assign I guess...
lizmat "Any container's default may be overridden by the C<is default(VALUE)> trait."
jnthn Is that connected to Nil assignment? 09:27
lizmat "If the container's contents are deleted, the value is notionally set to provided default value; this value may or may not be physically represented in memory, depending on the implemention of the container.
yes
jnthn ugh
Yeah, I keep ignoring implementing that on purpose.
Hoping it changes.
Sometimes this approach works. :)
lizmat it doesn't work for native types
jnthn Right, it can't. :) 09:28
It just means every single variable assignment needs to check this special case...
lizmat well, actually, it is specced to work for native types, as long as the default value can be represented
jnthn I guess it can be a type check failover...
lizmat jnthn: why would that be with every assignment?
I mean, we would need something special for Nil assigment 09:29
jnthn OK, every assignment we can't statically analyze. Which is the common case.
Yes, so you need to check, every assignment, if the thing on the RHS is a Nil.
lizmat ah, yes, but that hasn't got anything to do with "is_default"
jnthn As I said, that could happen because the assignment typecheck fails and then before throwing we say "oh, is it because it's Nil"?
Well, it has 'cus "is default" is where the default value comes from when Nil is assigned... 09:30
lizmat yup, and *then* check for any is default after we determine it was Nil
jnthn Right, it's the Nil check we'd need. But since it can be a type check fallback, it ain't so bad. 09:31
lizmat indeed...
jnthn wakes up a bit more and realizes that isn't the bit of type system cheating that bothers him.
lizmat what is? 09:32
jnthn The thing I absolutely do NOT want to allow is sub foo() returns Int { } to hand back a Failure. If we do that, we're utterly screwed.
lizmat wouldn't that work in a similar way then?
jnthn Well, the only way it can work is if we immediately throw the exception in the failure before it leaks out. 09:33
The problem is 09:34
moritz is for abolishing Failure anyway
jnthn foo(something-that-returns-Int())
moritz is dispatched to the foo(Int) variant, which unboxes
jnthn So, the optimizer sees Int, picks the multi-candidate for foo, says "oh, I can inline it and I can completely skip type checks too"
moritz boom
jnthn Then somebody gets upset because they get the "Cannot unbox Failure as a native int" they deserve.
Returning a Failure is fine...if you don't promise to return an Int. 09:35
masak right.
lizmat I guess the alternative would be to not let the optimizer pick multi-candidate at cimpile time :-(
jnthn Well, if we do that, we may as well forget Perl 6 ever being fast. 09:36
nwc10 jnthn: is there a test yet for foo(something-that-returns-Int()) ?
jnthn nwc10: I'd hope so :)
nwc10 ie, soething that tries to enforce sanity
lizmat will look, otherwise I'll add some
jnthn nwc10: Remember that infix:<+> (as in, addition) is an example :)
nwc10: Since all operators are function dispatches too.
r: sub foo() returns Int { fail 'oops' }; foo() 09:38

jnthn And it's fine with the type constraint gone.
nwc10 OK, specifically, is there a test that the error doesn't happen in the wrong place? 09:41
lizmat closest appropriate place I could find was t/spec/S06-signature/types.t, and it doesn't have any tests like that 09:46
09:46 dayangkun left 09:50 raiph left
lizmat so I'm looking at making my class X::TypeCheck::Assignment resume on assignment with Nil 09:53
so, would making a method "resume" or "resumable" in there do the trick? 09:54
jnthn No
lizmat should I look at something else to do ? :-)
jnthn That exception is thrown somewhere internals-y and ain't gonna be resumable.
But you can still probably fix it 09:55
I think the place to look is inside the container spec for Rakudo scalars
lizmat any particular files ?
jnthn After the type check fails, but before throwing an exception...
src/vm/parrot/guts/container.c or so, and there's a similar container-related .java for JVM too 09:56
masak .oO( "look inside the container spec" sounds like a kind of dumpster diving )
lizmat will see if I can make something of that
09:57 cognominal left, cognominal joined
lizmat so where is ->type_check defined? 10:01
jnthn Somewhere over in the nqp repo, iirc 10:02
Probably in sixmodelobject.[ch]
lizmat ok
jnthn That never throws, it only returns true/false
So it doesn't need changing; the change is to react if it's false.
lizmat ah, so not returning false on Nil as the RHS, is not the way ? 10:03
jnthn No, type_check should never lie. It's the low level thing. 10:04
It's the surrounding code that should cheat.
"Oh, you gave back false? Well, before throwing an exception, let's see if the RHS is Nil..."
lizmat jup
jnthn It's not a general type checking thing, it's a special case in assignment.
lizmat I guess "is default" would need to be known at this level then as well 10:06
so it can change the value to be asisgned
assigned
jnthn Yeah
That probably wants to live in container descriptor 10:07
lizmat is feeling completely out of her league now :-)
jnthn src/Perl6/Metamodel/ContainerDescriptor.nqp iirc 10:08
It's not a complicated object :)
lizmat says you :-)
jnthn I suspect the code you're looking at already accesses it, fwiw :)
lizmat trying to wrap my head around it 10:10
jnthn If it helps to know, a Scalar basically has a $!value for the value in the scalar, and a $!descriptor which points to a ContainerDescriptor containing the type, rw-ness, etc. 10:11
So it's really the "static aspects" of a scalar.
lizmat gotcha
10:20 fgomez left
lizmat jnthn: my progress so far: gist.github.com/lizmat/5899824 10:30
lines 41/42 in the gist are the pb for me now
jnthn lizmat: good start 10:31
value = cont->default;
desc->default, no? :)
See types.[ch] for how to cope with Nil
lizmat yup
ok, thanks
jnthn You may have to update container.h also to add ->default.
lizmat ok 10:32
jnthn We rely on P6opaque laying stuff out like a C compiler would. ;)
At least, in the cases when we are.
*care
10:32 lelf``` left
lizmat can I have a struct element with name "default" in C? 10:36
tadzik I don't think so
jnthn No, it's a keyword
_default
lizmat maybe better : the_defauilt ?
the_default ? 10:37
jnthn or that :)
tadzik I think the standard says that underscored things may be reserved in the future
see also: _Bool, or whatsitsname
lizmat I guess then I would have to rename the attribute as well, right ?
jnthn No
Names don't matter at all in C
It's all compiled down to offsets in memory. 10:38
lizmat ok, but it would have to be a PMC *, right ?
like value
jnthn Yes
PMC *the_default;
lizmat :-)
jnthn Note that you'll need to set it to something too :) 10:39
World.pm, see install_lexical_container or so
lizmat cool
jnthn Note that the real "default" handling will need some work. But for now, the Any or whatever can go in there
So my Int $x; ... $x = Nil; sets it to Int at least. 10:40
pmurias jnthn: it's not possible to serialize nqp subs?
jnthn pmurias: Hmm.
pmurias: There are some things that get code objects in NQP and some that don't...
lizmat if nqp::existskey(%cont_info, 'default_value') { # seems some support for default values is there already 10:41
jnthn I forget about how a Sub will be. I guess multi subs must get 'em so there's a place to hang the signature...
lizmat: Yes, that's the Mu/Any distinction.
lizmat: I do sometimes plan ahead a little :)
lizmat: It's probably already computing the correct thing to stick into the $!default you just added. :)
lizmat: At least, in the absence of an "is default" trait. 10:42
lizmat except it's called "default_value" here
jnthn Well, %cont_info is a compiler-internals hash.
It's not related to anything in the outside world.
It currently sets what ->value of the Scalar contains.
Thus the name. 10:43
pmurias jnthn: I'm fixing BEGIN for nqp, and I'm having problems with serializing &say, etc.
jnthn pmurias: I'm pretty sure BEGIN has no clue about its outer lexical scope...
Oh, you're trying to fix that...
:)
Um. Hmm. :)
pmurias yes
jnthn Yeah, some things I put off for a reason :D
I think the answer may be to look at giving subs code objects always, not just when they're multi. 10:44
See Rakudo's compile_in_context, though, if you didn't already.
pmurias I'm stealing code from compile_in_context, will look at it more ;) 10:46
jnthn: to create a code object, I need the orginal QAST (so they can be fixed up), so by the time I get the none-sixmodel code ref in the BEGIN handling code it's too late to do anything? 11:00

masak lizmat: yeah, fixing. 11:22
jnthn lizmat: Why? 11:25
If you say
my Int $x;
Then $x defaults to Int, you can only assign an Int, and you can only bind an Int.
lizmat but I would expect the default value to be set there already if one was specified 11:26
jnthn From the default trait?
No...we won't implement it that way
We'll set it to that as a default, then apply the traits later and it can fix it up.
lizmat r: my Int $x is default(4); # from this
camelia rakudo 567941: ( no output )
jnthn Right, it'll create it as Int for all of them.
lizmat r: my Int $x is default(4); say $x # expect 4 11:27

lizmat ok, so the actual assignment of the default value for that specific container, needs to happen later?

FROGGS can somebody explain what that means? github.com/libtom/libtommath/blob/...rshd.c#L28 12:20
tadzik well, if you shift by more digits than a has, it zeroes a, which sounds like a fair deal 12:22
unless I misunderstand a->used
FROGGS I have no idea what ->used is
moritz a->used is indeed the number of digits used
FROGGS hmmm
do I need to compute that?
moritz where "digit" is usually 30 bits on 32 bit platforms, and ~50 on 64 bit platforms 12:23
no
FROGGS because mp_rshd( 50000, 1 ) results in 0
moritz it does that for you
FROGGS hmmm
moritz well, maybe the problem is really that you expect bn_mp_rshd to shift by b bits 12:24
and it shifts by b digits
orelse the code is buggy
FROGGS ohh
moritz what does the documentation say about mp_rshd?
FROGGS shift right a certain amount of digits

okay, back to the previous plan 12:26

TimToady it's less worse :)
on returning Failure, even if you outlaw that on --> Int, you still have the problem of returning an Int type object 15:16
15:16 xinming joined
timotimo OK. and the answer to Failure is: "use fatal can make it execute as fast as if Failure didn't exist"? 15:16
TimToady but at least it will dispatch to the right multi before failing :)
jnthn TimToady: Yes, but that's fixable with returns Int:D :)
timotimo does --> Int:D make any sense?
jnthn Which is what the constraint really should be saying. 15:17
TimToady well, the question is whether we default all our types to Maybe/Error types or not
if it adversely impacts performance, I can live with --> Int being a kind of 'use fatal'
jnthn TimToady: It means we can't trust a retursn declaration for making an inlining decision, which feels high impact to me.
TimToady timotimo: yes, that should work too
jnthn: I understand the argument 15:18

jnthn Sink is a more interesting one because it's the thing that lets us know when we don't need to build up result lists.
So it can help as well. :) 15:20
TimToady it's basically serving the role of the IO monad
15:20 xinming_ joined
TimToady saying when side effects are expected 15:20
15:21 xinming left
timotimo how high is the percentage of cases where sinkness can be determined at compile time? would there be any value to compiling two different versions of each method and compile-time switching to the definitely-sunk version? 15:21
or is that not even the problem?
TimToady timotimo: most of the time it's compile-time; it's the run-time aspects that are debatable
but then, the same argument applies to lazy/eager/hyper/race
"How much does my caller care about when things happen?" 15:22
timotimo mh 15:23
TimToady if we can limit that handshaking to listy calls, then scalar calls don't have to do that sort of handshaking
but this is one of those areas where we're doing research :) 15:24
15:24 FROGGS left, bluescreen10 joined 15:25 Khisanth joined
timotimo is there a :Something that means "defined or undefined, both is okay"? 15:26
so that it would make sense to turn --> Int into --> Int:D by default 15:27
TimToady but perhaps the called function doesn't really get involved; it just returns a listy thing, and the caller then instructs that listy thing which context it's in; this would save having to pass context inward
timotimo: I don't think we should try to DWIM that
:D is short for a reason 15:28
timotimo makes sense
it would be a healthy default for performance i guess ... what about the "use fatal" thing i wondered about before?
TimToady Haskel picks the other default, and has to add Maybe/Error monads all over
we just pick the other default
timotimo ah, yes, that's a sane choice indeed 15:29
sergot hi! o/ 15:30
TimToady another thing is that I'm not entire sure we should always be optimizing for inlineability; there are hardware architectures where function calls are just about as fast as inlined code, and may be faster depending on the caching
on such architectures, inlining actually slows you down 15:31
moritz then you don't inline :-)
timotimo but are these calls actually at a level that would make those hardware details turn out different?
15:31 xenoterracide joined
TimToady yes, it's a different level, but the same principles *might* apply 15:31
timotimo we're not yet generating machine-level instructions, and even if so, that would probably be more interesting for the jit rather than the compiler 15:32
TimToady I just don't want to get blinders that make us focus on one optimization
timotimo fwiw, i don't know terribly much about optimisation and just grasping at any straw that claims to make perl6 run faster ;)
TimToady fundamentally, it's knowing the types that allows for optimization; inlining is just one possible manifestation of that 15:33
but the whole notion of gradual typing is not forcing people to put types where they don't contribute much to optimization
timotimo that's a good point 15:34
moritz but when you declare a type, you should rely on it being enforced, no?
TimToady moritz: sure, that's what I'm agreeing with jnthn++ about 15:35
but the flip side is whether Failure is a "bottom" type 15:36
15:36 Pleiades` left 15:37 xinming joined
TimToady my current feeling is that we don't yet know enough about type theory in Perl 6 to introduce a bottom type efficiently 15:37
15:37 xinming_ left
TimToady it also might be a bad idea to think that a bottom type could carry failure information :) 15:38
15:39 FROGGS joined
TimToady so for now I am content that Failure should be a conceptual type (like Junction) that sits outside of Any 15:39
15:40 Pleiades` joined
TimToady (assuming the default return type is --> Mu, or it won't work) 15:40
shachaf Is the main point of "gradual typing" really optimization? 15:41
TimToady the main point is user convenience while not ruling out writing faster code when you want to
user convenience comes first because the system may be able to optimize it anyway based on dynamic performance characteristics 15:43
timotimo right, the JIT approach?
TimToady beyond JIT, even
hot path analysis
certainly a realm where the JVM has done some work 15:44
timotimo ah; what pypy has, the tracing jit, is probably a combination of what you mean + a jit
shachaf I mean that I don't think of optimization as being the point of types in the first place. But I see that's not the topic of the discussion here anyway.
15:44 rindolf joined
TimToady sure, optimization is not the main point of types 15:45
nor is strong typing, in Perl 6
it's really to be able to express multiple dispatch
that's the main point of types in P6
timotimo i like having my stupidest mistakes pointed out to me directly at compile time, too, which is possible only if you specify types here and there
TimToady yes, and P6 is allowed to point out such mistakes when it can deduce them, but it's not the main reason for types in P6 15:46
15:46 Guest1337 left
TimToady the real reason for types is to allow you to write code of the correct genericity/specificity for the problem 15:46
which ties back to the notion that we know exactly which language we're in 15:48
which may be a generic language, which is fine as long as it's on purpose
but accidental genericity is what kills things like source filters
as you add more multis, you are gradually increasing the intentional genericity of that call
and that's a good thing 15:49

pmurias jnthn: nqp::freshcoderef(sub {}) breaks when wrapping everything in code objects, should I just extract the sub from the code object? 15:57
jnthn pmurias: yeah
All the code* ops expect to work on a CodeRef REPR or whatever the equivalent is on the current backend 15:58
pmurias should we have a method on code objects to return the code ref? 15:59
extracting $!do by nqp::getattr is kind of ugly
jnthn Yeah, but we shouldn't be doing it too often... 16:00
pmurias everytime we call a code* op 16:01
well, almost every time
jnthn yes, but most usages of those are *inside* the code object where you have $!do
And there are methods like .name or .clone
pmurias so maybe we should move nqp::freshcode inside a fresh method? 16:02
jnthn That'd be better

Woodi belives in one type of optimalisation: do less 16:22

yeah, I'm aware that speed isn't the fastest 17:54
at this speed it doesn't seem very practical for me to use perl6 to make changes to large files, but I'm sure I can find other ways to incorporate it
like maybe automating tasks that I need to do on lots of things? I'll figure something out
FROGGS I'd say it comes to use when perl5's regexes are just too unreadable 17:55
then the Perl 6 grammars are just awesome
djanatyn mmm
FROGGS and there might be some other reasons of course :o)
djanatyn well, this file is only 18M
a lot of the files we work with here are several gigabytes, so if it's taking that long using perl6 regexes doesn't seem very practical 17:56
FROGGS true
djanatyn but like I said, there's lots of other stuff we do here, so I'll look out for new ways to use perl6

because if not that will kind of limit the use of the 4096 available cores 18:22
jnthn djanatyn: No, but now there's a JVM port making good progress I'm hoping to work on that rather soon.

pmurias: you mean the v5 module?
pmurias yes
using the Perl 5 setting in a 'use v5' scope 20:30
FROGGS I thinnk the solution was not to inherit from Perl6::Grammar/Actions
and to have the EXPORT sub in v5.pm
I almost cant remember what the trouble was :o) 20:31
there is no Perl 5 setting
lizmat jnthn: it feels like " if ( STABLE(value)->WHAT == Rakudo_types_nil_get() ) {" is not triggering in container.c
suggestions?
pmurias FROGGS: so what happens when you call a perl5 sub? 20:32
FROGGS I just make the P5 special vars available, and dispatch the Perl 5 builtins to methods on P6's types
pmurias: what do you mean? a sub declared in a v5 block or a P5 "builtin"?
jnthn lizmat: Hm, is Nil a type? 20:34

jnthn pmurias: Ah...but I guess the clone doesn't actually do a take...

It just copies
takeclosure I *think* does the two

lizmat why remove the "is Iterator" ?
that's what I've just stubbed in BOOTSTRAP, no? 21:17

lizmat what what what ?
jnthn lizmat: See the lines started below # Fill out EXPORT namespace.
TimToady an argument could be made that Nil is a conceptual type like junctions; in fact, one could posit that Nil is an alias for one(), that is, the simultaneous requirement that something be one thing and zero things :)
jnthn You need a line there to actually export the Nil that you've crated.
*created
lizmat checking
jnthn That's probably why the extra "is Iterator" in the setting doesn't explode.
TimToady in any case, if Nil were put outside of Any, we'd have to do something like with junctions in order to use Nil to represent the absence of an argument to the binder 21:36
lizmat jnthn: indeed, Package 'Nil' already has parent 'Iterator' 21:37
so src/core/Nil wouild need to have its "is Iterator" removed? 21:38

timotimo i just tried to open for writing and it didn't work, but perhaps opening for reading does
jnthn The IO stuff wants a good look over, I think...
timotimo ah, i know what's going wrong 22:53
i wasn't terminating the line with ;1 in the repl and stringifying dies because .tell doesn't exist
method read_bytes not found, heh. probably because it operates on something called $!PIO ;) 22:54
jnthn *sigh* yeah, and that probably depends on Buf... 22:55
timotimo *of course* IO is among the last things to get running in a perl6 implementation ;) 22:56

timotimo kind of bummed i don't get to see line numbers for src/gen/CORE.setting in jvm :| 22:59
well, i do, but only for one stack level it seems 23:00

timotimo looking forward to the new vim version with the alleged new and much faster regexp engine for highlighting and such 23:07
hopefully scrolling through perl6 code no longer stutters :P

timotimo oh, i made more tests succeed! :) 23:21
gist.github.com/timo/4b4dc754a509ff0a14b7 <- i don't want to make a pullrequest for such a peanut change. please apply it, someone? 23:22
(should make 46 tests pass!) 23:23
jnthn hm...
I wonder if that means our Makefile.in entries are mis-ordered compared to on Parrot... 23:24
timotimo oh, good question
jnthn That shouldn't be needed on one and not the other.
timotimo otherwise these should fail on parrot, too
jnthn Right.
I'd rather fix that.
Gonna go rest now.
timotimo good, do that. i'll delete the gist.
jnthn Back tomorrow...should have a few more tuits tomorrow also :) 23:25
Feel free to tweak the ordering and test it... :)
'night o/
pmurias jnthn: adding a capturelex solved the strange error 23:28
timotimo pulling only Exception.pm back to the front gives an NPE, but i'm trying to put the whole block that had been moved back to where it is on parrot 23:29
seems like more work that i'd care to handle right now. i'll probably go to bed instead 23:31

timotimo fixing the build order will also transform Could not find symbol '&Chdir' into Failed to change the working directory to '/home/timo/build/jakudo/./t': java.lang.NoSuchMethodError: org.perl6.nqp.runtime.Ops.chdir(Ljava/lang/String;)Ljava/lang/String; 23:50
