Zoffix I got some proptests failing, but they look iffy to me. A shift on `int` variable expects -170141183460469231731687303715884105728 as a value 00:02

Zoffix Some of the tests in that bunch are already fudged with RT#125466 00:05
synopsebot RT#125466 [open]: rt.perl.org/Ticket/Display.html?id=125466 [MATH][@LARRY] bitwise shift is inconsistent on int
Zoffix "There are three fudges where it's unknown what the proper behaviour should be (overflow or switch to Int?)." yeah, mine fall into that category too, so I'm just gonna fudge them (they're proptests, not spectests) 00:06
Zoffix votes "overflow with natives" while at it
.ask TimToady what's your opinion, should `use nqp; dd nqp::bitshiftr_i(-9223372036854775808, -64)` overflow and return -9223372036854775808 or switch to an Int instead -170141183460469231731687303715884105728? Right now we have this inconsistency between Int and int candidates, but I'm leaning towards: people might wants overflowing stuff 00:11
yoleaux Zoffix: I'll pass your message to TimToady.
Zoffix MasterDuke: rindolf the native shift candidates should now work, as of github.com/rakudo/rakudo/commit/3d73597556 00:17

Zoffix TEttinger: why overflow? You couldn't for example do `my int64 @a = -9223372036854775808; @a[0] +>= -64` for example. It'd explode 00:32

Zoffix OK, yeah, I'm changing my vote on that the two should behave the same.
cfa hmm, it looks like Array tucks slice adverb documentation away under grep
TEttinger Zoffix: overflow matters for some algorithms and there should at the very least be an option
Zoffix TEttinger: oh, right I misread what you originally said. 00:38
TEttinger JS is just a mess regarding ints and overflow
Zoffix Yeah, that was my original reasoning too, but the above evals show this isn't a good method to rely on when it comes to controlling overflow. 00:39
TEttinger since Number doesn't actually support 64 bits of integer precision on JS
cfa actually, that's coming from list
MasterDuke perlawhirl: "is a branch mathematics", missing an "of" i assume 00:40
Zoffix .tell TimToady I changed my leaning; I think both HLL and native should behave the same as autoboxing makes stuff too unpredictable as can be seen here: irclog.perlgeek.de/perl6/2018-03-05#i_15883977
yoleaux Zoffix: I'll pass your message to TimToady.

xiaoyafeng but look this code: my %dd = ( a => 3, b => 3, c =>4); (keys %dd).min({%dd{$_}}); 05:38

do I miss something? 05:39
shinobi-cl m: my %dd = ( a => 3, b => 3, c =>4); say %dd.minpairs; 05:40
camelia (a => 3 b => 3)
shinobi-cl maybe minpairs is what you need
m: my %dd = ( a => 3, b => 3, c =>4); my %smallest = %dd.minpairs; say %smallest.keys; 05:42
camelia (a b)
xiaoyafeng Thanks! let me check minpairs document;) 05:43
05:44 xtreak joined
ZzZombo `min` returns values 05:47
shinobi-cl sure. BTW, if you don't want to use a temporary hash (%smallest) you have to use this:
m: my %dd = ( a => 3, b => 3, c =>4); say (%dd.minpairs.hash).keys;
camelia (a b)
ZzZombo why the parentheses in `say`? 05:48
shinobi-cl oh, sorry those were a leftover of what i was testing... you do not need those :P 05:49
xiaoyafeng so .hash means explicit conversion to hash type? 05:52
shinobi-cl yes, for some reason, minpairs returns a Seq, not another hash. but using .hash fixes that 05:54
m: my %dd = ( a => 3, b => 3, c =>4); say %dd.minpairs.perl;
camelia (:a(3), :b(3)).Seq
xiaoyafeng one more question, is there a count like function in perl6? I find classify, similar but not equal. how translate below perl5 code to perl6? count_by {$_}, (a,a, a, b,b,b c,c) 05:56
will return a => 3, b => 3, c => 2;

People keep saying how small our ecosystem is, yet everyone's so keen to add stuff to core. 13:03

Nope. 13:06

El_Che Zoffix: I thought the versioning of the lang was to have a license to break stuff, with a compiler/implementation targetting x versions 15:16
wishful thinking, then :) 15:17
Zoffix El_Che: not at all what I'd call it. People wouldn't be too keen on using a language that keeps changing everything from under them all the time. Even though you can specify a language version, if you do so, it means you cannot use latest features in that file and I can't imagine latest compilers supporting ancient language versions indefinitely. More-over, the language-versioning doesn't help much with 15:20
objects and method implementations (what does a 6.c version file meant to do when it's given a 6.d Str object?)
El_Che true 15:21
Zoffix Even with the things we *are* able to change, I'd never call it "license to break stuff", but "diminishing impact from fixing stuff"
rakudo.party/post/Perl6-On-Specs-V...d-Breakage
I imagine some driven person will eventually create a fork of Perl 6. It'd not have "Perl" in the name and it won't have billion methods most people won't need in core. It'd also polish all the inconsistencies before releasing the stable version (or even before releasing a publicly available version). 15:22
And would have full tests and documentation of everything. 15:24
AlexDaniel well good luck to them, but I'm pretty sure we'll fix the name before that happens :) 15:25
El_Che hehe
Zoffix + puritanical standards of development: mandatory tests, docs, and justification for all features, and consistency review for how the feature and its behaviour fits with the rest of the language.

And App::Cpan6 is by the same author, so I bet the same is the case there.

timotimo zoffix, you can make it about 20% faster by making the \Token parameter required - that prevented the jit from jitting that frame.
23:17 lichtkind joined, Zoffix joined
Zoffix timotimo: well, wow! With that change I get it nearly 50% faster. 18s vs P5's 17s 23:18
timotimo oh my
Zoffix timotimo: so JIT can't jit anything with optional params? Should we look through core code and see if anything could have optionals eliminated? Also, how did you figure out that that wasn't being jitted?
timotimo first i ran it with --profile to see that calc_S, which was at the top of the routines list by "exclusive time", was 100% red on the right side 23:19
then i used MVM_JIT_LOG to find the line that starts with "BAIL:" after the line that has "calc_S" in it
Zoffix m: say 33.298/18.634
camelia 1.786949 23:20
Zoffix Yeah, changing Token to mandatory param makes the program 78% faster
timotimo it was param_op_o, which is "get a parameter that's optional, positional, and object typed"
you probably got a better improvement because i used a much smaller workload
jnthn Most of the time, optional parameter ops are rewritten and never make it do the JIT 23:21
So something must have blocked that rewriting
timotimo potentially OSR-related 23:22
because calc_S was only called a single time and relied on OSR to get jitted at all
Zoffix I don't see calc_S line at all in jit log 23:23
timotimo somehow p6box_I comes out at 14.5% inclusive time in a perf report
Constructing JIT graph (cuuid: 1, name: 'calc_S')
this is what it ought to look like
Zoffix $ G calc_S j.log
2018.02.1 zoffix@VirtualBox~/R/rakudo (master)$
timotimo that's strange, can you send the jitlog file and maybe the shell history over? 23:24
Zoffix Ah, I don't have debug options in moarvm. Does that matter?
timotimo shouldn't matter
the --debug option in moarvm's Configure.pl just instructs C compiler and linker to keep debug symbols around, i.e. which memory locations in the binary correspond to what functions and variables and such
it's important for debugging with gdb 23:25
Zoffix timotimo: wget temp.perl6.party/j.log; and I made it with `MVM_JIT_LOG=j.log ./perl6 ../z.p6 > /dev/null` where `./perl6` is 2018.02.1-118-ga5a6c7786 built on MoarVM version 2018.02-27-g760b0913e and ../z.p6 is gist.github.com/zoffixznet/3e3d31a...fe59704470 23:27

timotimo that's certainly interesting
Zoffix ZofBot: where'd you put the meth cache? 23:28
ZofBot Zoffix, And he said, “Yes, it’s the -to-
23:28 Ven`` left
timotimo why it doesn't show up at all ... no clue :( 23:29
but now it's fast, so ... :)
Zoffix It shows up if I also set MVM_SPESH_BLOCKING=1; maybe program exits before it get a chance to write that out? 23:30
mhm, if I add `sleep 2` at the end of the program, it shows up even without SPESH_BLOCKING 23:31
timotimo a speshlog would tell us if it got to specialize it before it quit
it shouldn't take long enough to spesh that so that it could fail to install :o
Zoffix Maybe it installs but quits before writing to the file? It's like a 20MB file 23:32
timotimo oh, that could be, yeah 23:33
so, if we had an op that turns a native int into a str without going via Int, that'd make this thing faster 23:34
at least i think so
Zoffix nice
timotimo nope, barely a difference at all 23:35
23:35 cdg joined
Zoffix :) 23:35
timotimo what allocates all these Int objects ...
7757486 Int objects
Zoffix I got `nqp::say(nqp::concat(nqp::tostr_I(nqp::box_i(Token, Int)), 23:36
nqp::concat(' ', nqp::tostr_I(nqp::box_i($ip, Int))))),
there. Could that be it?
timotimo i commented that out and it still allocates that much
Zoffix m: say 18.287/17.735 23:37
camelia 1.031125
timotimo it's barely a difference at all
Zoffix .tell rindolf I got P6(NQP) version fast enough to be to just 3% slower than P5: gist.github.com/zoffixznet/6082e29...4d7426791c
yoleaux Zoffix: I'll pass your message to rindolf.
timotimo not getting line numbers because nqp code :S 23:38
rindolf Zoffix: hi
yoleaux 23:37Z <Zoffix> rindolf: I got P6(NQP) version fast enough to be to just 3% slower than P5: gist.github.com/zoffixznet/6082e29...4d7426791c

Zoffix And 2s is what it takes to compiler it, so I'd say my original challenge completed: I got P5 beat (despite the final result being NQP soup appreciated by few:P) 23:39
s/compile <( r// 23:40
m: use nqp; my int $x = 42; for ^10 { say nqp:add_i($x, 1) } 23:41
camelia ===SORRY!===
Lexical with name '$x' has wrong type
Zoffix why u say dat?
oh right, nqp int != P6 native int 23:42
right?
timotimo no, that should be compatible
Zoffix Ah lol 23:43
m: say 'nqp:add_i'.comb(':').elems
timotimo um yo
camelia 1
timotimo check what happens when you turn $ii into int, too
Zoffix damn, I thought it were an int alread y:o 23:44
timotimo it may surprise you
Zoffix Woooohoo!
Actually, this is what I originally was expecting when I started on this journey :) 'cause that other program I rewrote in NQP was a bunch faster than P5 23:45
m: say 17.735/7.168
camelia 2.474191
timotimo that's more like it. 23:46
Zoffix rindolf: timotimo++ made the program 2.5x FASTER than Perl 5 :D gist.github.com/zoffixznet/4df7a30...fb65bbb0a4
timotimo can you measure with MVM_JIT_EXPR_DISABLE=yes ?
Zoffix 0m6.904s 23:47
timotimo so a bit faster, yeah?
Zoffix Yeah
timotimo how stable is that measurement?
23:47 vike left
Zoffix 0m6.813s 0m6.976s 0m6.874s 23:47
timotimo OK
well, brrt has lots of ideas for making the exprjit smarter :) 23:48
Zoffix Sweet :)
timotimo with $fkE at 25, the program runs the GC a single time 23:50
rindolf Zoffix: nice 23:51
23:54 pierre joined
timotimo given ~2 seconds of that are parsing the code - no doubt because of the huge array of primes at the start - it's pretty good 23:56
