geekosaur er, of combining codepoints
00:00 luser1 left
geekosaur if you hadn't noticed, rx:perl5 is not complete (and I would say in this example not correct) 00:00
probably as NYI as the modifiers :bytes etc 00:01
I'm testing them locally in perl5
remember that in perl 6, the string '"̃"' itself has only one character in it: a synthetic codepoint 00:03
..,wow, hexchat mangled that
teatime well that string has two
but yes I understand it doesn't have three 00:04
geekosaur yeh, I copy-pasted and hexchat doubled the "
but that means that rx:p5 would have to undo that to work just like perl 5, and it doesnt know that it needs to do that
so it's matching more than it should with ^.
teatime yes
I understand it's nyi, that's fine 00:05
geekosaur if youi do it in actual perl 5, it matches only one codepoint
teatime I was just testing and hoping.
interestingly, putting a ZWNJ after the opening " does not break up the grapheme, either to perl or on my terminal
would have thought it would
geekosaur I think that's a known glitch 00:06
actually ZWNJ is misrecognized/misimplemented all over the place
teatime I figured P6 would implement that w/ maybe 50% probability, but really shocked it doesn't work in my terminal
geekosaur I think jnthn ran into that while developing the current grapheme implementation

zwu I understand it is too early to test the performance of perl6, due to my interesting, I tested perl6 performance for the same task at github.com/famzah/langs-performance, sorry I don't have the perl 6 code right on my computer, but from my test on perl 6 April release, it is about 18x slower than python2. 01:01
the benchmark of other language performance are there.
The code for perl 6 is very similar to other code for the implementation, I could post it tomorrow too. 01:02
gfldex it is for sure not to early to test the performance of Perl 6. It is however to early to expect the same performance then a language that was released in 1991. 01:03
timotimo please ping me with the code when you have it :)
zwu here is the benchmark of other language: blog.famzah.net/2016/02/09/cpp-vs-...mark-2016/
timotimo i wonder if you used "int" or "Int" in the perl6 code 01:04
zwu I used Int and @array using push
timotimo wow, your get_primes7 has a prototype definition 01:05
in the perl5 code, i mean
zwu so that could be the performance problem.
timotimo not necessarily :)
zwu btw: it is not my code on the git github.com/famzah/langs-performance.
timotimo as long as the numbers don't exceed 32bit, we at least don't allocate a full mp_int
but we're currently pretty dumb when it comes to creating far too many intermediate boxed results, and we have a few things that immediately prevent inlining in some cases, which really hurts performance 01:06
but all in all, 2016 is the year where many performance improvements will be made
zwu I believe there will be many performance improvements !!! 01:07
timotimo just yesterday lizmat gave Int a little performance optimization pass with results like div and / for Int, Int being about 50% faster
01:08 molaf left
timotimo i'm interested in running the code you came up with under --profile 01:10
zwu ok, I put my primes.p6 code there gist.github.com/anonymous/f31c6b7e...9a1085894, sorry for I didn't create a github repo. 01:14
timotimo not important, a gist is good enough 01:15
there seem to be some tab characters mixed in there :) 01:16
how long does it take on your machine, approximately?
zwu 531 seconds 01:17
run at a virtual machine. 01:18
for python2 it is about 31 seconds.
timotimo thanks
i'll probably have my sleep before actually working on this, though

timotimo already a c-level profile reveals 8.2% spent in total just marking an array of objects 01:28
17% of overhead related to invoking frames, which means the optimization we're going to get this or next week will give a decent benefit here even before the code itself has been optimized 01:29
well, i'd even go as high as 25%

gfldex it's filling up 1.3GB of RAM 01:38
timotimo it's going gc-crazy, too 01:39
01:39 Actualeyes joined
timotimo 69660380 Int objects, 59977737 Scalar objects 01:39
01:39 Actualeyes left
timotimo and an astronomical amount of BOOTHash, which i'm not 100% sure about their correctness 01:40
gfldex does `Int(sqrt($n))` acutally create an Int obj, even if the result ends in `int`? 01:41
timotimo "ends in"?
gfldex like in `my int $mroot = Int(sqrt($n))`;
timotimo just by sprinkling a few "int" around, i get from 272504.78ms to 159403.75ms
(but this is only 5 runs, not 10)
it will create an Int, yes 01:42
gfldex m: my @primes = (1..10000000).grep(*.is-prime); say @primes.elems;
timotimo i see a tremendous amount of IntLexRef being generated, which tells me my nativifying is doing the "stop all inlining now!" thing 01:43
camelia rakudo-moar ec6c3b: OUTPUT«(timeout)»
01:43 BenGoldberg joined 01:45 ilbot3 left
timotimo gfldex: wanna try out if you can do better than the loop that puts odd numbers into the @s array? 01:46
like with a "..." for example
or by using the return value of a loop 01:47
01:47 ilbot3 joined
gfldex i would like to keep the algorithm the same for a start to see how far I get that way. I do know the max size of the result array, so a native shaped is worth a try. 01:48
timotimo no, definitely not native shaped; they are currently the opposite of optimized 01:49
they will give you terrible performance
01:50 cdg left
timotimo it seems like 3, 5, 7 ... * > $n is slower than the loop with push in it :) 01:50
gfldex if it gets cache friendly it may still lead to a win
timotimo no. no, it will very much not be. it will still be 100x slower than a regular native array 01:51
01:51 cdg joined
timotimo do a small test up front and you'll see just how terrible performance of shaped arrays is right now 01:51
01:52 mohae joined 01:55 huggable left, huggable joined
timotimo wow, using the return value from a loop causes the program to run about 2x as long, and also eats up more than 2x more memory 01:55
01:55 cdg left
BenGoldberg If you use := instead of = for the array assignment, does it speed it up? 01:57
timotimo i don't have an array assignment at the moment; do you mean for the loop, or for a "..." call?
using int32 for the arrays makes memory usage a bit lower, but has nearly no impact on run time
BenGoldberg 'my @res = get_primes(10000000);' vs 'my @res := get_primes(10000000);' 01:59
Also for doing 'my @s = do loop ...' vs 'my @s := do loop ...' 02:00
timotimo the @s will be modified later on, so just putting a Seq in there won't fly 02:01
02:01 cpage_ joined
timotimo no change between = and := 02:02
er
it halves maximum resident set size, but it doesn't make things faster
better than half, actually
BenGoldberg Ok, what about replacing the 'for @s' loop with 'return @s' 02:03
Hmm, need to do unshift(@s, 2), first, to make the results correct. 02:04
timotimo wouldn't that change semantics?
BenGoldberg ?
timotimo that for loop basically implements .grep(*.so) 02:05
BenGoldberg Oh, I see.
Ok, then how about unshifting 2 onto the front of @s, then doing 'return @s.grep: @.so;' 02:06
Without putting stuff in @r. Actually, I don't think @r is really necessary.
timotimo i'm trying
the "original"(?) python code has the result thing anonymous in a return clause 02:07
return [2] + [x for x in s if x]
BenGoldberg That can be mimiced with 'return 2, |(@s.grep: *.so);' ... I'm not sure which would be faster. 02:08
timotimo my attempt at that makes it slower and use more memory
i'm going to bed 02:10
BenGoldberg G'night, then.
timotimo i have a hot water bottle waiting for me in bed <3 02:11
have fun with the benchmark, if you're going to continue working on it :) 02:12

AlexDaniel mmmhm…
I haven't thought about it
12:08 wamba joined
timotimo i suppose the reason for grep with a block is slower is because we don't have trace jit yet, which means it'll invoke a code object for every single test 12:09
whereas in the for + if that's in-line for free
moritz maybe laziness is to blame
jnthn `@a.push: |@b` is a pretty bad idea :) 12:10
timotimo hm, append won't try to eagerly nom the whole list?
that'd be a bad miss :)
or do we want it to act like "plan"?
jnthn It actually flattens all the arguments
Into the callsite
timotimo yes, that's pretty terrible 12:11
AlexDaniel @s .= grep({$_}); @r.append: @s; is slightly faster than everything
jnthn And produces a callsite descriptor along the way
timotimo it'd end up like a triple copy of the whole list
jnthn Yeah, plus making the huge callsite descriptor. And, worse, while the argument limit in MoarVM is fairly high, the one on the JVM is 255 iirc.

AlexDaniel looking at this comparison again, I think that it is pretty stupid. If you look closely, then in both P5 and suggested P6 versions there is a temp array @r that is there for no reason 12:42
while in e.g. python version there is no such thing
in perl 6, getting rid of this @r array actually makes things significantly faster 12:43
RabidGravy gosh the chromaprint api is really rather simple
timotimo AlexDaniel: in the python version it returns [2] + [a for a in s if a] or something 12:49
which is equivalent to @r

AlexDaniel and if you use @s as an array of native ints, then indeed it does

RabidGravy I looked at that a while back, decided it was too complicated to do quickly and for forgot about it 12:55

ZoffixW Why?
stmuk I don't think there is any module to read it 13:02
RabidGravy I made one in C# once
ZoffixW ugexe, doesn't look like #86 got resolved. I'm still having the same issue. That's after nuking everything and starting from scratch (github.com/ugexe/zef/issues/86)
stmuk ZoffixW: or was the Q why I don't like YAML? :) 13:03
ZoffixW stmuk, no, you said "more", so I assumed we already had YAML and needed more :)
I don't like it either
sortiz Any code review/comments/suggestions will be appreciated. 13:04
ZoffixW It's the Python equivalent of configuration files 😂😂😂
stmuk yes the whitespace sensitivity is a misfeature
RabidGravy it was the new hotness back in, oh, 2002 13:05
timotimo we have one yaml module that doesn't work, iirc 13:06
stmuk YAMLish looks hopeful 13:07
sortiz The json-c library is a little more permissive than JSON::Fast, so five 'should fail to parse' tests fails. 13:08
AlexDaniel anyway, here is the what I got: gist.github.com/AlexDaniel/ce3c60e...bedea03ff5
13:08 brrt joined
timotimo sortiz: that's not "permissive", that's "wrong" :) 13:08
AlexDaniel it runs about twice faster
but I am sure that there is a way to make it even faster if you manage to get rid of this .grep 13:09

timotimo my uneducated opinion is that once we have trace jit, TCO becomes a potential possibility 14:20
probably a case of "SMOP", with all the things that entails
jnthn We don't in general know if anything "downstream" will do things like CALLER::
I think the question isn't "can we do TCO some of the time" 14:21
It's "can we do it predictably enough that can rely on it happening"
Can we do it at all is "surely yes", it's the latter I'm highly doubtful about.
timotimo oof. 14:22
14:22 pierre_ left
timotimo right, fair enough 14:22
grondilu Could we not have a Calleable type that would prohibit anything that's incompatible with TCO?
jnthn Even if that's a dynamic prohibition?
(You'd get a runtime exception for doing something incompatible with it, that is) 14:23
grondilu jnthn: I don't know, but you make it sound like TCO is impossible or something. Some languages do it, just do whatever they do.
jnthn That's stupid. 14:24
grondilu rude
jnthn Other languages can do it because they made the trade-offs.
Saying "in return we can't do X"

jnthn Language design is always trade-offs. 14:25
pmichaud good morning #perl6 14:26
grondilu my concern is that there are function that are very much easier to write recursively, but we always end up not writing them because of performance issues. That's very LTA.
jnthn And the langs I know where you can rely on tail calls all made it so you can analyze that.
o/ pmichaud
MadcapJake jnthn: could you explain a bit what the trade-offs are for TCO? I'm not following what the CALLER:: argument means
jnthn MadcapJake: In various languages, it's possible to staticly analyze things such that you can rewrite a recursion into an iteration. 14:27
MadcapJake: That relies on you knowing that you won't break anything in the process of doing so.
14:27 perlpilot joined
jnthn MadcapJake: And as a result of the rules around when it happens being fairly simple, folks can write code relying on it. 14:28
In Perl 6, various features make that static analysis fraught while others mean we simply can't do it.
14:28 wamba joined
pyrimidine jnthn: re: recursion to iteration, IIRC there is a fair amount in Higher Order Perl that covers doing so (for p5 of course) 14:28
pmichaud aren't C<nextsame> and C<nextwith> supposed to help with tailcalls? Or is that a fossil? (Or are we strictly discussing automatic TCO?) 14:29
14:29 ZoffixW joined
jnthn The moment you make a method call, it's late-bound and you don't know whether that code will do anything, like access CALLER::. 14:29
pmichaud: They're for iterating through pre-determined candidate lists. They potentially could make use of tail call optimization, though you could construct cases where the optimization would break things. 14:30
pmichaud I guess nextsame/nextwith aren't recursive tailcalls. But perhaps they point the way to there.
ZoffixW Is anyone feeling adventurous and wants to add Perl 6 to CodeMirror? :P codemirror.net/mode/index.html
jnthn method foo() { my $*x = 42; nextsame() }
Does the thing you nextsame to see $*x or not? 14:31
ZoffixW The Perl 5 version is 800 lines long :( Perl 6 version would probably be much larger: github.com/codemirror/CodeMirror/b...rl/perl.js
MadcapJake ZoffixW: I'm partway through a highlightjs mode but I got discouraged when I discovered heredocs were impossible
timotimo i think we already have a bit of codemirror for perl6
jnthn (The answer today is "yes"; replacing the callframe would change that answer, for example)
ZoffixW MadcapJake, :( 14:32
timotimo github.com/azawawi/farabi6/blob/ma...l6-mode.js <- ZoffixW
MadcapJake timotimo: that isn't usable actually, it's basically a copy-and-paste of perl5-mode
jnthn nextsame today functions as return callsame(...)
ZoffixW Yey! timotimo++ azawawi++
timotimo OK, sorry about that
pmichaud jnthn: and yes, I'd expect nextsame to be that way.
MadcapJake ZoffixW: do not use that, azawawi informed me that it's not implemented beyond just copying perl5-mode into a new file
jnthn It's really tail calls as a language feature, vs. tail calls as an optimization. 14:33
ZoffixW MadcapJake, aw. Too bad
jnthn The latter I'm pretty sure we could do in some cases; the former is a lot harder than "just copy what another language does". 14:34
pmichaud jnthn: agreed
ZoffixW MadcapJake, how come heredocs are impossible?
14:34 dakkar left
pyrimidine jnthn: could you indicate a method can be TCO, e.g. method foo() is tco { ... } 14:34
MadcapJake ZoffixW: the highlight.js lexing engine doesn't support capturing delimiters and reusing them
ZoffixW Ah 14:35
MadcapJake there's an issue in their tracker wrt to it and the author basically says "not possible and we're not implementing it any time soon"
ZoffixW :/
jnthn pyrimidine: What would that actually do?
I mean, sure we can indicate things, but what semantics go with it? 14:36
MadcapJake ZoffixW: I started a CodeMirror perl6 mode a little ways back actually (I forgot about it :). I'll try and get it finished this week (perhaps more likely next)
ZoffixW Sweet. No rush :)
jnthn If anything, the "this is a tailcall" mark would want to go on the call that should function that way.
ufobat ZoffixW, thanks for the PR
jnthn Which would mean you're explicitly saying "and if anything downstream isn't OK with that, it's my fault" 14:37
pyrimidine jnthn: yeah, true
ZoffixW ufobat, no problem
timotimo there's monsters in the basement preventing me from TCO! :(

MadcapJake jnthn: In Perl 6, if you use {call,next}{with,same} and multi-dispatch heavily, will you run into issues? Because I think TCO is really about supporting that recursive paradigm more than anything and if we can support it without TCO then it's kind of a moot point. 14:43
14:43 khw joined, perlpilot_ is now known as perlpilot 14:44 perlpilot_ joined
MadcapJake CIAvash: ok it's on the todolist! I usually only have so much syntax highlighting juice in any given month though :P 14:44
jnthn MadcapJake: {call,next}{with,same} aren't for recursing anyway, they're through walking through (usually short, pre-destined) lists of implementations, so you can defer control to a more general candidate. 14:45
CIAvash MadcapJake: nice :) 14:46
jnthn MadcapJake: If you write heavily recursive stuff today - yes, you'll allocate a lot of stack frames.
And yes, tailcall as an explicit language feature is a lot more hopeful in Perl 6 than TCO.
MadcapJake jnthn: ok so those keywords are more about the dispatching than about recursing. specifically call{with,same} would seem related to recursion, at least at first glance. 14:47
nine_ I think there's still the endless loop issue with nextsame 14:48
14:48 dakkar joined
jnthn nine_: Yeah, that one should never be able to happen. I think I figured out how to fix it though: capture the frame that set the dispatcher. 14:48
nine_: And check that it's the caller of the thing trying to take it.
Then it won't be stolen by accident 14:49
Alternatively, we might be able to fix it with better code-gen.
nine_ jnthn: sounds like a step or two above my pay grade, so I'm no longer ashamed that I couldn't fix it :)
jnthn Just by forcing the takedispatcher to be earlier.
nine_: I dunno, I think you've done plenty of trickeir things ;-)

nine_ Well I guess things usually seem much less tricky after you've done them ;) 14:50
jnthn Don't they just...
jnthn looks forward to the current invocation changes he's doing seeming much less tricky... 14:52
MadcapJake I think another point wrt tailcall/TCO: Perl 6 has much more powerful iterative facilities that make recursion not so necessary.

pmurias MadcapJake: TCO is only truly necessary in functional languages 14:55
the python philosophy is that they won't implement it because it's not worth having worse stack traces 14:58
MadcapJake pmurias: yeah, as much as I like to think of Perl 6 as multi-paradigm, it seems there are certain things that require you to become entrenched in a particular paradigm (like TCO here). 14:59

brrt or, well, it depends on whether your semantics include this notion of the stack
keep a parameter 'i'm N tail calls deep', reconstruct the stack trace, done :-)
actually, call trace 15:20
but anyway
i'm nitpicking
perlpilot brrt: have you ever had to debug a Perl 5 program where perl optimized away some of your call frames?
brrt my point is that the stack is an implicit assumption of routine local storage, which is not necessary to specify in a language
no, haven't, actually
that's using goto right?
ZoffixW goto is the explicit way 15:21
perlpilot no, using goto you did it to yourself

mst if nothing else I expect most of my toolchain stuff to remain perl5, since perl6's "we want to be completely cross platform" means that perl5 is much better at unix and I'm not sure it's worth 'fixing' that in perl6 when perl5 already exists 18:10

mst (1) no, actually, C is not that portable between unices unless you're extremely careful, you will learn this the hard way one day, grasshopper
grondilu jnthn: personal question : have you always developed on Windows or did you switch from a Unix background?
mst (2) I'm talking about *my* toolchain, as in the toolchain I'll use to deploy stuff, not rakudo's build system
mspo netbsd is portable c 18:17
but since linux switches all of its components every two years...
mst: oic
mst and netbsd being 'portable c' will help your parallel code run properly on windows how?
mspo mst: from what I thought "toolchain" meant, bootstrapping perl6 made sense 18:18
mst if you remove the word 'my' from the sentence I actually typed and replace it with something else, you get a different sentence
mspo in terms of "portable c" and "careful c", I was just giving an example 18:19

there's lots more cross-platform differences in C

DrForr Heh. When I first had access to servers to deploy webby stuff to it was mostly Solaris + Sybase.
arnsholt You can write portable, bug-free C in the same sense as you can juggle machetes. Very, very carefully 18:26

jnthn I'm really lazy, so I suspect Windows will survive as the primary OS on this box until it's time for a new one, at which point I'll probably go for something else. :)

jnthn :) 18:33
Don't think I even encountered it, so yeah, no chance for me :)
mst I'm assuming if you'd spent a couple years on it you'd also've fallen in love, but that's because I'm biased as all get out and assume anybody with a clue would fall in love with it given the chance

MadcapJake for a nativecall module, is it expensive to use `is symbol` trait a lot?
ZoffixW It's perfectly fine methinks. Really, saying "you write a ternary like ?? !!, not ? :" should be enough :P
DrForr Thanks. I'm making sure there's a solid foundation, but I also want to make sure to repeat things to increase retention.
MadcapJake I like that Perl 6's ternary is very distinct from other operators 18:43
jnthn MadcapJake: I wouldn't imagine so, no 18:44
MadcapJake: It just takes that name rather than the sub's name to do the lookup in the native lib
ZoffixW It composes a role to do so 18:45

why it is terrible?
DrForr dupek: Sanity? Which admittedly is in short supply in the Perl community. And look at the year.
MadcapJake A Perl 6 shell would be great but a whole OS? 18:52
mst because perl isn't a systems language
DrForr dupek: Enough would have to be implemented in C to get reasonable performance that it's pointless.
mst neither perl is a systems language, and that's ok

ufobat sena_kun, junctions were implemented, but never in the testcases. I 19:21
sena_kun, i realized that i dropped them out of the code when i already replaced the "old" routing with the nested routing feature 19:22
sena_kun, and i think you don't realy need it since the regex way (rx{ ^ [ '/h' | '/help' | '/halp' ] $ }) is basically just another "syntax" to achive the same behaviour 19:23
sena_kun ufobat, do you plan to fix the example then? 19:24
ufobat sena_kun, but still you're right.. do you really need this? i am currently thinking about just changing the example
sena_kun ufobat, no, I don't need this, I just tested the examples and notice that one of it is broken, then reported it. 19:25
ufobat yeah! :) thanks for the report!
i think i'll think about it and probably fix the example :) 19:26
RabidGravy I would say that being able to use a junction would be useful because it would enablle you to calculate a set of routes eaier
easier
ufobat easier? in what way? 19:27
sena_kun ufobat, also, do you have any roadmap/todo list? I'd like to dig into bailador codebase and looking for some(probably easy) tasks. Or issues page is my hope? 19:28
RabidGravy you add to an array and then use that to create a junction for instance, rather than building a string regex
ufobat RabidGravy, i see 19:29
but is it a common usecase to create the route destinations "dynamically"?
skink Anyone got an appveyor script that doesn't take an eternity?
ufobat thats what you're describing, right?
sena_kun, i am currently a bit.. i dont know how to say it ;) 19:30
disapointed is not the right word
RabidGravy yeah, if you are making a higher level inferface
ufobat and thinking about it, is not negative enough ;)
i am thinking about the differences between the http/p5sgi/p6w servers and the specification, supplys vs Blobs and stuff 19:31
RabidGravy, i see. hmm.. currently i think its hard to implement, because the "route" itself once was a Pair and now is a Bailador::Route 19:32
i guess you need to change the type in the Bailador::Route to be no longer just a regex but also a junction... 19:33
sena_kun, if you want to PR something easy, i guess its easy to implement that you have a <HTTP-ERROR-CODE>.xx template in order to customize error pages
19:34 ZoffixW joined
ufobat sena_kun, currently i am working on file uploads multipart/form-data vs url-encoded stuff 19:35
ZoffixW I don't see how much easier Junctions make anything. The usecase in question is using a junction to make a route work off multiple URLs... Is that really a common thing to do? I can't think of a single time I ever needed it in the past 8-9 years
sena_kun ufobat, okay, I'll look into it, thanks. 19:36
ufobat sena_kun, i think RabidGravy? did suggest to write a PSGI app that "tests" the specification. thats on my roadmap as well. but not really bailador related more a Devel::PSGI module
sena_kun, if you have questions or suggestions don't hesitate to talk to me :) 19:37
