AlexDaniel jnthn: for the upcoming “why didn't we find it earlier?” question: I guess we're lucky? Toaster tries to install modules twice in an attempt to deflop things, and given that this *sometimes* doesn't segfault it managed to go through with Succ status 00:27

AlexDaniel timotimo: I mean… there's already a for ^8 loop here: gist.github.com/AlexDaniel/a09652a...ster-p6-L1 00:29
a lot of *able6 functionality is somewhat obsolete now given that you can use multifile gists and stuff 00:30
Geth rakudo/master: 8 commits pushed by (Elizabeth Mattijsen)++
AlexDaniel the reason I do things like HEAD,HEAD,HEAD,HEAD is because it works around single commit timeout of 10 seconds :)
and that simply needs this functionality: 00:31
committable: timeout=50
committable6 AlexDaniel, I cannot recognize this command. See wiki for some examples: github.com/perl6/whateverable/wiki/Committable
AlexDaniel github.com/perl6/whateverable/issues/317
timotimo: also, toaster itself should deflap and bisect things: colabti.org/irclogger/irclogger_log...08-12#l652 00:32
but honestly I feel like I won't have any time to work on this :( 00:33
my available free time already goes into releases and stuff, especially when they're hard like this 00:34
timotimo you're always 100% free to reject my dumb spontaneous ideas/outbursts :)
AlexDaniel well, flappable6 idea is of course rejected, but there are other things we really should improve 00:35
timotimo also, i don't say nearly often enough how i value your release work \o/
on top of the whateverables that are already splendid
AlexDaniel thanks
b🦋sectable: help 00:38
hm, I wonder why that doesn't work 00:39
b🦋sectable6: help
timotimo perhaps it only looks at what's up to the first space

AlexDaniel that is deliberate I think 00:40
timotimo OK
AlexDaniel hm, I think IRC::Client itself doesn't recognize it as a valid nickname 00:41

it can't talk
timotimo p6bannerbot isn't running on hack, at least 00:50
AlexDaniel oh ok
p6bannerbot: help
timotimo oh, could it have happened when it got flood-kicked?
yeah, only statisfiable6, bloatable6, and notable6 got voice
AlexDaniel timotimo: oh, I have a feeling p6bannerbot is not identified 00:51
hm, looks like it is 00:52
so why is it not giving out voices
00:52 committable6 left, committable6 joined, ChanServ sets mode: +v committable6
AlexDaniel ↑ here it got voice for a different reason, not because p6bannerbot is working 00:53
timotimo well, that last time it got kicked while voicing
because it was voicing too rapidly
and when it reconnected it didn't continue it seems

doesn't work with return
timotimo yeah, needs return-rw or no return

or hm… 🤷
.tell nine fwiw here's a module that perhaps wants to be fixed :) github.com/tony-o/perl6-module-does/issues/3 01:41
yoleaux AlexDaniel: I'll pass your message to nine.
AlexDaniel ok hold on turns out there's one last module check :) 01:42
timotimo hah 01:52
AlexDaniel yeah, that's it. Just closed R#2230
synopsebot_ R#2230 [closed]: github.com/rakudo/rakudo/issues/2230 [⚠ blocker ⚠] Pre-2018.08 toasting
AlexDaniel so here's all that we have left: github.com/rakudo/rakudo/labels/%E...0%E2%9A%A0 01:53
misc.rakudo.moar is likely just a test that needs to be tweaked
clang issue existed before, so not exactly a blocker
and JVM on windows… no idea, someone just needs to check if it works I guess
this SEGV is perhaps more difficult 01:54
but we'll see how it goes, maybe jnthn will have some insight
or maybe someone will come up with a golf :)
.tell samcv current status: colabti.org/irclogger/irclogger_log...08-20#l152
yoleaux AlexDaniel: I'll pass your message to samcv.
AlexDaniel .tell jnthn any pre-golf thoughts on R#2231 ? 01:55

Ulti is that test-t --race the parallel version of P6 is now faster than the P5 XS implementation single threaded? 09:36
|Tux| yes, BUT ...
Ulti there's always a BUT
|Tux| --race is just possible on CSV files with no embedded newlines anywhere and where the order of the CSV records does not matter 09:37
CSV is per definition a stream, which cannot be broken to "lines" and shared amongst processes
Ulti so --hyper being as fast is the real win I guess 09:38
I think thats still quite a cool result though plenty of people just want to get through a CSV with records not needing to follow in an order, logs especially you have timestamps to define an order per record anyway 09:39
that the scheduler is capable of saturating on threading that quickly too
assuming the test CSV isnt huge
|Tux| I spoke to someone doing 30 Tb of CSV a day :) 09:40
Ulti I've noticed that going parallel recently is a lot more profitable than it used to be even on small amounts of data
|Tux| they used perl5 with a stripped Text::CSV_XS with all I/O layering removed
Ulti usually I go raw IO for that if its a CSV format I can make some assumptions about 09:41
which is never true in reality :(
|Tux| :)
Ulti but yeah VCF in bioinformatics is essentially a glorified TSV and plenty of places will have TB of those a day they are parsing through 09:42
