jnthn TimToady: I was wondering if hyper and race as prefux are really going to work out well, in so far as .hyper and .race opt you into that processing model, and putting them "on the end" doesn't work quite so well 11:21
11:22 brrt joined

brrt good *
have we any idea on the panda breakage yet? 11:30
nine jnthn: can't the compiler generate the @a.race.map code for race for @a?
brrt: not that I'm aware of
jnthn nine: Prolly, though TimToady++'s patch didn't do that, which is why I'm moting it :)

brrt i've ruled out: reprop devirt, different compilation strategies, and i think i've ruled out extop misjit, but not 100%
i mean different compilation output 11:31
jnthn Is it inline sensitive?
OSR sensitive?
nine brrt: are we sure that my code is actually correct? Maybe it works more or less by accident and the JIT just breaks what ought to be broken anyway?
brrt it seems pretty correct to me
jnthn nine: The JIT should not change semantics

Revert "Make rand xx N about 2.5x faster"

Alas, some subtleties of xx are not covered by this patch. And the easy fix does not seem to re-introduce the original behaviour. So reverting for now until we get more info.		 12:28
12:28 aiacob left
lizmat fwiw, giving up on speeding up xx for now... it is a tangled web 12:29
nine lizmat: it's strange that a 2 line implementation can contain such subtleties 12:31
lizmat have you looked at the inside of GATHER lately? :-) 12:32
in any case, I'm not sure what the required semantics are anymore
[] xx 2 should that be ([],[]) or () ?
12:32 aiacob joined
nine lizmat: good point :) 12:33
lizmat with one arg rule, I would think () and that you need $[] xx 2 to get ([],[])
but that's not the current (tested) behaviour, afaics
ShimmerFairy I see xx as "take this thing, and copy it a bunch", so one-arg rule doesn't make much sense to me at first glance. 12:36
lizmat m: dd (1,2) xx 2

lizmat m: say (1,2) xx 2
camelia rakudo-moar b5a5bf: OUTPUT«((1 2) (1 2))␤»
lizmat that's the wrong behaviour I introduced today 12:37
(1,2) should get flattened
however, if I add code to do that, [] gets flattened to () as well 12:38
I guess I need smarter code than @!cached = $!x.() 12:39
12:39 laouji joined
nine Evaluates the left argument the number of times specified by the right argument. Each evaluation is in list context, and returns a Seq. The result of all these evaluations is returned as a list of arrays (which will behave differently depending on whether it's bound into a flat context or a lol context). 12:39

i wonder why replacing the ".elems == 0" with some boolification makes it b0rk
14:14 hernanGOA joined
lizmat because .elems vivifies ? 14:17
*reifies ?
timotimo fair enough, but isn't boolifying supposed to get the "does it give at least one item" as truth value?
14:18 dustinm` joined 14:20 Ven joined 14:23 Ven left, araujo_ joined, araujo_ left 14:24 laouji joined
lizmat well, yeah, but for now, it just checks elems afaik 14:24
I actually added a "bool-only" method to Iterator yesterday
14:24 araujo_ joined
lizmat that would allow to only fetch one value to determine truthness 14:25
14:25 araujo_ left
lizmat self.pull-one() !=:= IterationEnd; 14:25
timotimo ah, neato 14:26
that probably fits here
we'd .Bool on the result of a .grep to get that, for example?
lizmat timotimo: thing is, that method is not getting called just yet 14:27
14:27 araujo left
lizmat making Seq.Bool call that method, breaks quite a few spectests :-( 14:27
timotimo OK, that's for the future in that case
oh? strange
14:27 araujo joined
lizmat a lot of cases of Seq has been consumed 14:27
timotimo ugh, damn 14:28
14:29 laouji left
nine That's gonna be hard to avoid while retaining the performance gain :/ 14:29
timotimo perhaps things where you'd "if @foo { say @foo }" ?
14:29 araujo left
Ulti timotimo cool I can add it to the other ones and see how it does :) 14:29
timotimo please do 14:30
hm, though in that case we've assigned to a @var already
14:30 araujo joined
timotimo isn't that what triggers memoization? 14:30

timotimo in the code i pasted, we could use .first, though, right? 14:33
14:33 yqt left
lizmat hmm.... ok, forget the grep opt 14:33
we appear to have to handle "last" in grep as well... 14:34

timotimo hum, that explodes 14:34
lizmat I don't see how I can pull that off in a pull-one (pun intended :-)
Ulti is just building a fresh rakudo and running all the primes benchmarks
timotimo you can just have a CONTROL block, though?
lizmat hmmm.... 14:35
I'm not sure how to set that up, actually...
timotimo not quite as performant as having an "only handle LAST" thingie, though
Ulti oh neat someone fixed the bug with panda?

timotimo d'oh
well, we're doing all numbes up to $max in any case 14:51
Ulti I kind of expected that though since there is a lot of overhead added to something thats a very vectorisable cacheable numeric algorithm

mrf is going to need to learn how to generate unicode chars from his keyboard to program p6 15:35
Ulti so the parallel one is about ten times slower.... but its also doing a lot more work since all the others are only comparing to the primes already found below the square root the parallel one doesnt have any of that cache so actually its doing a lot more work and still got a reasonable time
and it is working :)
timotimo mrf: we have a piece in the doc about that 15:37

15:57 Ven left
timotimo Ulti: "the" grep? but there's two greps ... so perhaps the one that does less work just has too much overhead? 15:59
i'm not 100% sure how the things work, but it's likely that a race that gets set up the very same way over and over again (i.e. the inner loop) doesn't re-use things it might be able to if it were hand-tuned? 16:00
Ulti timotimo: yeah
I think if I removed the inner loop it might work out better
I'll give it a go

Ulti as the greps without the race
:(
timotimo oh, damn 16:07
but it uses more cpu time?
as in: it maxes out more than one? 16:08
Ulti oh yeah
16:08 telex left
Ulti its basically 4 times as bad since its using that much CPU for the same task 16:08
timotimo argh, wtf?
could it not be splitting up the tasks at all? 16:09
Ulti well its got 4 threads and ends up being a little slower
for the same load
timotimo could it be giving all the work to all 4 threads?
Ulti might be
*shrug*
that would be it not working as specced though right
timotimo right 16:10
but what do i know :)
16:10 telex joined
Ulti I suspect it might be something like batch says how much to consume before splitting out a thread? so it ends up just making threads and the first finishes before the second starts 16:10
yeah going to 8 from 4 threads slowed it down 16:11
timotimo i haven't looked at what the arguments to race do; i only remember that you can leave the arguments out and it'll try to come up with something sensible 16:12

bartolin I consider going through roast and replacing all (or as many as possible) occurences of eval-dies-ok/dies-ok with throws-like. 18:29
For code which fails with X::AdHoc, I wonder if it would be better to test for X::AdHoc or Exception. There was a short discussion about that yesterday: irclog.perlgeek.de/perl6/2015-09-21#i_11253577
Since jnthn++ suggested to audit the remaining non-typed exceptions before christmas, I guess it would be better
to test for X::AdHoc for now. That way we see failures in roast when upgrading to typed exceptions and can adjust the tests accordingly.
Do you have any thoughts on that? 18:30
Optionally, all X::AdHoc could be changed (back) to Exception shortly before releasing 6.christmas (to become more stable wrt throws-like) 18:31

lizmat so we can just add a "dd" to code while debugging code to see where it goes 22:22
especially handy when verifying which Iterator candidate is used while processing a Seq 22:23
timotimo Ulti: that might come from our new IntStr (and friends) support?
but i thought they unbox as ints just fine ...
lizmat goes to bed dreaming of Seqs :-)

ShimmerFairy timotimo: it appears to be an issue in Range.iterator, fwiw (at least, that's where the top line of an --ll-exception stacktrace points) 23:13
