patrickb .tell rba raku.org is down. Can you have a look? 07:54
tellable6 patrickb, I'll pass your message to rba
patrickb ping rba
tellable6 2020-12-03T21:30:43Z #raku <samcv> patrickb no I don't use Raku at work, sadly
2020-12-03T22:05:51Z #raku <tony-o> patrickb i'm interested in it, for sure. ot
2020-12-03T22:06:34Z #raku <tony-o> patrickb it's been kind of a pain in my side, though. i have a working prototype and the code to run it. i need to figure out how to make it work in zef.
2020-12-03T22:06:56Z #raku <tony-o> patrickb in response to your ecosystem inquiry.

nine lizmat: Thanks for finding those! That's exactly what I wanted to look into today as raku -e '(^10000).race.map({EVAL "q:to/END/;\nEND\n"}).sink' still fails very rarely with some message about a cursor 08:53
Though it looks like those are not actually the reason for the failures I see. 09:25
nqp: class Foo { }; role Bar { has $!bar; method set-bar() { $!bar := 1; } }; my $i := 0; my @threads; while $i < 16 { my $thread := nqp::newthread({ while 1 { my $foo := Foo.new; Foo.HOW.mixin($foo, Bar); $foo.set-bar } }, 0); nqp::push(@threads, $thread); nqp::threadrun($thread); $i++ }; nqp::threadjoin(@threads[0]); 09:26

nine Locally this immediately gives me "Unhandled exception: P6opaque: no such attribute '$!bar' on type Foo+{Bar} in a Foo+{Bar} mixin when trying to bind a value"
Which is the same as during compilation: P6opaque: no such attribute '$!named' on type QAST::IVal+{QAST::SpecialArg} in a QAST::IVal+{QAST::SpecialArg} mixin when trying to bind a value 09:27

nine Oh, it seems like the error happens either immediately or not at all. This suggests that the race condition is in generating the mixin. Once all threads get the type from the parametrics cache it seems to be fine 10:09

Use still slightly faster explicit nqp::add_i vs prefix ++

Looks like the ++$i codegens to a bare IVal, whereas the nqp::add_i codegens to a WVal containing an IVal. Yet the WVal version turns out to be about 1% faster in benchmarks still.
13:08 morayj joined 13:10 domidumont joined
[Coke] going forward, would it be worth keeping an optimizations used doc that has things like "using nqp::_add_i instead of ++ for <reason>" so folks looking to make optimizations (and then code updates for readability over speed) have a list? 13:16
lizmat [Coke]: well, this particular case I hope we can fix soon, either by changing the codegen of ++$I to use the WVal form, or even better, figure out why the bare IVal form is slower 13:18

Add :emit-(once-)on-empty to Suppy.batch(:$seconds)

With :emit-on-empty, you *will* get an emit even if the batch is empty. So that means you will get at least 1 emit for every $seconds.
With :emit-once-on-empty, you will get an emit once if the batch is empyty, and no further emits until more values have been received.
rakudo: 492651ea48 | (Elizabeth Mattijsen)++ | src/core.c/Supply-coercers.pm6
Add :emit-timed to Supply.batch(:$seconds)

When :emit-timed is specified, a timer will be running emitting whatever is in the batch every given number of seconds *if* there is something in the batch. The default is to only emit if a new value is received and it arrives in a new period.
This removes the previous proposal for :emit-on-empty and :emit-once-on-empty.

[Coke] lizmat: I know you just did a big update to the nqp ops markdown - I updated the "are these opcodes tested" test to be raku as well, lots of misses at the moment. Let me know if you want me to make a ticket out of that or something. 16:07
16:09 bazzaar joined 16:18 bazzaar left, [Tux] left 16:29 [Tux] joined
lizmat [Coke] are you saying that the update lost documentation? 16:34
[Coke] no.
lizmat *phew*
[Coke] I'm saying we have lots of opcodes that aren't being tested
lizmat tested as in: not having documentation, right ? 16:35
if so, please make an issue of the current state of undocumentedness
[Coke] ... no
I mean not in t/
lizmat aah.. ok
still worth making an issue for :-) 16:36
[Coke] ok. will do
(the missing docs is already a separate ticket)
lizmat ack
[Coke] NACK
lizmat ? 16:40
[Coke] just replying to your ack, nothing. 16:43
lizmat ack :-) 16:51
[Coke] lizmat: added untested/unused opcodes to github.com/Raku/nqp/issues/686 16:55
though now that I've done that, I see that... sqrt_n shows up in the list, but it's in t/ 16:56
whoops. :)

Allow for multiple opcodes per line
[Coke] lizmat: there, that's about 20 that were being tested or used that we properly track now. still 154 opcodes that are documented and not tested/used in build. 17:06
lizmat [Coke]: thanks, will probably look at that tomorrow 17:07
working on a pretty big RWN now
[Coke] thanks. as with everything, I'm cheating there, so "improve the test" is always an option. 17:08
MasterDuke [Coke]: i get `Malformed UTF-8 near bytes 00 00 b2 in block <unit> at t/docs/tests.t line 37` when i try to run that doc test 17:52
