Make Map.pick()/roll() about 7x faster

  - on a 26 element Hash, larger hashes faster still
  - doesn't need to build a list of Pairs to select from
  - so much easier on the memory
  - instead loops the iter a random number of times
  - and *then* builds a Pair on the iteration where stopped		 08:24
lizmat wonder if we would want to implement a Hash.grab 08:25
samcv grab?
oh i forget what baggy thing i wanted
maybe i will remember
lizmat m: my $b = <a b b c c c>.BagHash; dd $b.grab; dd $b 08:26
camelia "b"
BagHash $b = ("b"=>1,"a"=>1,"c"=>3).BagHash
lizmat afk&
samcv oh lizmat i wanted to be able to add more thnigs to a baghash 08:28
with the same semantics as (foo,bar).BagHash
my $bh = (1,2,3,3,2).BagHash; $bh.add(2,8,9)
lizmat, if you add that I will be very happy 08:29
you can grab things so would be nice if you can add things 08:30

jnthn Ah
It doesn't implement it, just inherits the auto-viv from Any
But given Hash does implement .push that may be more consistent
lizmat noted 09:52
m: my $bh = BagHash.new; $bh<a> = 42; dd $bh # samcv: like this ? 09:53
camelia BagHash $bh = ("a"=>42).BagHash
samcv that edits the baghash, what i'm looking for is adding elements from an Array and have it be as easy as creating/semantically similar as creating a BagHash 09:57
sleep &
night o/
lizmat nighty night!
m: my %bh is BagHash; my @a = <a b c>; %bh{@a} = 1 xx *; dd %bh 09:58

jnthn m: my %bh is BagHash; my @a = <foo bar foo baz bar>; %bh{@a}>>++; say %bh
camelia BagHash.new(foo(2), baz, bar(2))
lizmat that too :-) 09:59
and better :-)
jnthn Yeah, I think the 1 xx * one doesn't do the right thing if there's repeated elements?
lizmat but that looks to me like the semantics that BagHash.push should allow
jnthn: yeah, that's why yours is better :-) 10:00

MasterDuke_ what's the difference between a VMString and a BOOTStr? 14:01
jnthn BOOTStr is a boxed object, VMString corresponds to str 14:02
MasterDuke_ i think you were talking about this recently, but are VMStrings much more efficient than BOOTStrs? 14:03
jnthn Yes, in that they save an allocation 14:05
Zoffix What does BOOT stand for?
jnthn (Of the box)
Zoffix: Bootstrap
Zoffix Ah. Thanks.
timotimo strings powered by twitter 14:06
MasterDuke_ a heap profile of `-e ''` shows 35,705 VMStrings and 14,963 BOOTStrs. any way to see where the BOOTStrs came from? 14:13
AlexDaniel m: use experimental :macros; macro infix:<plus>($a, $b) { return quasi { {{{$a}}} + {{{$b}}} } }; say 2 plus 3; 14:17
camelia WARNINGS for <tmp>:
Useless use of constant integer 2 in sink context (line 1)
Useless use of constant integer 3 in sink context (line 1)

AlexDaniel wow
it's working
I'm sure there's a catch somewhere (besides this useless use message) 14:18
timotimo MasterDuke_: we don't have anything like "origin tracking" or something
if you mean that
but the regular profiler will tell you what function allocated how many BOOTStr and such
MasterDuke_ yeah, but a regular profile of `-e ''` just shows one BOOTArray and one BOOTCode allocated 14:19
timotimo did you --profile-compile? 14:22
MasterDuke_ hm. that shows 557 BOOTStrs and 151 Strs, but no VMStrings 14:26
timotimo but VMString is just the REPR, and BOOTStr is one class that uses that repr ... at least i thought so 14:27
Zoffix m: say .posix == .earlier(:second).posix with DateTime.new: :2017year 15:02
camelia True
Zoffix Never realized that.
So, if you were watching the clock tick, it'd stop for 1 sec? 15:03
TimToady yes, try not to get an X-ray right then 15:38
yoleaux 2 May 2017 21:52Z <AlexDaniel> TimToady: You may be interested in rt.perl.org/Ticket/Display.html?id=131247
3 May 2017 15:39Z <Zoffix> TimToady: what do we do: due to a sequence of 2 bugs, `is-deeply` currently converts a Seq arg into a List and so falsely makes `is-deeply (1,).Seq, (1,)` pass, which causes 69 roast tests to fail (67 of which are 6.c-errata) and likely many module test suite failures as well. So, do we bite the bullet and fix is-deeply and tests or do we document the flaw and call it by-design?
Zoffix it converts Seq -> List only *args* themselves, it still will fail the test when testing, say, is-deeply ((1,).Seq,), ((1,),) 15:44
Zoffix is leaning toward "leave as is" 15:52
Test.pm6 is yuky as it is, so it's just another yuk 15:53
TimToady still wishes there was some way to write ordinary comparison operators with an option to hook them to tap output
so that you could just explicitly use 'eqv' but still get diagnostics that know the args 15:55
but the last time I pushed that idea was before we had a decent compiler :)
Zoffix m: use Test; cmp-ok (1,).Seq, 'eqv', (1,)
camelia not ok 1 -

# Failed test at <tmp> line 1
# expected: '1'
# matcher: 'infix:<eqv>'
# got: '1'
Zoffix boo at that output
TimToady I suspect we could now do it by overloading the comparison ops, and making 'ok' smart enough to look for "complicated" values of true/false 16:00
except, of course, that comparison ops have to be chaining, which might complicate things... 16:02
Zoffix m: class Foo {}; multi infix:<eqv>(Foo, Foo) { say "OK!" }; use Test; cmp-ok Foo, 'eqv', Foo 16:04
camelia OK!
ok 1 -
Zoffix Huh, weird. I thought that wasn't working
'cuase of this pos: www.reddit.com/r/perl6/comments/5l...h=69d8c6e1 16:05
Ahh.. that was using is-deeply
TimToady maybe cmp-ok is a macro? 16:06
or cheats by looking things up in the caller's lexical scope?
it's still notationally inconvenient 16:07
Zoffix You can use &[eqv] as well
It does: my $matcher = $op ~~ Callable ?? $op !! &CALLERS::("infix:<$op>") // &CALLERS::("infix:«$op»") // &CALLERS::("infix:<$op.subst(/<?before <[<>]>>/, "\\", :g)>"); 16:08
TimToady druther just write: ok Foo eqv Bar, "did stuff"
and make eqv smart enough to pass arg into to ok 16:09
and it still degrades gracefull even if your 'ok' isn't bootstrapped enough to do anything other than pure boolean
*fully 16:10
Zoffix What sort of arg?
Or both
TimToady *args
Zoffix Ah
TimToady m: say ([1,2] but False).perl 16:11
camelia [1, 2]
TimToady m: say ([1,2] but False).so
camelia False
TimToady m: say ([1,2] but False) ~~ Positional
camelia True
TimToady ok could see that it as a Positional and use that for its report 16:12
*has
timotimo role ComparisonOperation { has $.lhs; has $.rhs; has $.op }
TimToady can't typ ths mrnig
timotimo: or that
though it'd be nice to handle chains 16:13
so more likely a list that alternates args and ops
but that'll take more work in the parser (which we wanna do anyway)
on accounta chains are currently parsed as left-assoc and then reconstructed later as a hack 16:14
we need to teach EXPR how to return the alternating form 16:15
need that to allow proper user-level overloading of chains anyway
doubtless we could find a few additional yaks to add there... :) 16:16
mst only a few? 16:21
yoleaux 2 May 2017 13:01Z <Zoffix> mst: this looks like something you wanted to add to Perl 5. Any opinions? github.com/perl6/ecosystem/issues/334
mst I've seen toke.c
Zoffix holy crap. That's like a million comments on that Issue 16:22
mst comments with "no, fuck off, wait 2-3 years, btw I've spent 10 years working on this and think MY work should also wait 2-3 years" 16:24
samcv: my comments on github.com/perl6/ecosystem/issues/334 are totally down to how hard I found it to figure out an approach - basically "yes, we should have this if we can, but it may take as long to get this to work as it took us to get 6.c" 16:28

TimToady * doesn't close over anything, or closes over everything, depending on how you look at it; but there is no $_ inside for it to NOT close over

m: use QAST:from<NQP>; $ = QAST::WVal(Nil)
camelia ( no output )
Zoffix Like that, but I want it to actually execute the QAST stuff
timotimo you can manually run the individual stages of the compiler
Zoffix How?
timotimo each stage is "just" a method
Zoffix oh
m: use nqp; use QAST:from<NQP>; nqp::getcomp("perl6").ast: QAST::WVal(Nil) 22:16
camelia Cannot find method 'ast' on object of type (null)
Zoffix decides to repurpose perl7 compiler into a QAST debug tool 22:17
timotimo hm, i don't think that's it
Zoffix m: use nqp; use QAST:from<NQP>; nqp::getcomp("perl6").ast: QAST::Op.new: :name<say>, QAST::SVal.new: :value<Hi>
camelia Cannot find method 'ast' on object of type QAST::Op
timotimo you'd likely .mast and put in the qast 22:18
and the result of that you can then feed into .mbc
whihc, if you don't have a :output adverb, will run the code for you 22:19
Zoffix I got it. 22:27
Gonna turn it into a bot feature
timotimo neato 22:28
how do you feed the qast into the bot then? just as perl6 literal stuff with QAST::blah? 22:31
it'd be kinda cool if you didn't have to write QAST:: every time, as well as .new 22:32

samcv looks like it. i'll kill all the moar's
Zoffix \o/
timotimo it's dead, jim
samcv maybe should have it kill all of my users moar processes at the end of the script :P
Zoffix w00t
timotimo did it actually reach the end of the script?
samcv prolly 22:46
timotimo we should probably put a limit into collectd so it warns if the cpu utilization has been at >95% for all cores for over 24h or so
so we can check if anything is hanging
samcv gist.github.com/samcv/5339208c44a4...8e02dd0cee
timotimo alternatively, put in some ulimit d)
samcv it got 885 modules 22:47
