Add additional dashed variants for utf16le and utf16be

Add utf16-le, utf-16-le, utf16-be, utf-16-be as variants for utf16le and utf16be. This makes it consistent with the variants for other utf's including utf8-c8.		 01:10

Zoffix It's kinda weird. I would've thought it to demand a Callable that returns a `Meows` 01:47

AlexDaniel so if zef says something like this: CONFIGURATION /home/alex/.rakudobrew/moar-master/install/share/perl6/site/resources/4B6FE7F170929FBA2A501CB141A7B073111FA208.json 19:04
where the configuration file is some sort of a sha
does it mean that the config file is different depending on which version of rakudo you use?
19:05 brrt joined
AlexDaniel also, if I'm using zef with disabled auto-update, how is it going to behave when running on different rakudo versions? 19:05
does it need to fetch at least once per rakudo version or not?

yoleaux 19 Oct 2018 16:10Z <Zoffix> brrt: does R#2395 (Proc.in.close hang/long time) sound like anything you may have worked on or do you have any ideas about that ticket? I saw some commits about event loops in MoarVM. Dunno if that's what's involved in handling closing of STDIN for a proc (it uses Proc::Async under the hood)
synopsebot R#2395 [open]: github.com/rakudo/rakudo/issues/2395 [⚠ blocker ⚠] t/spec/S32-io/io-cathandle.t is now 2x-8x slower without precomp
yoleaux 19 Oct 2018 17:51Z <Zoffix> brrt: nevermind, I managed to bisect that ticket to post-release-opts merge in MoarVM, so it wasn't the event loop stuff. Still any ideas on what could be the bug welcome :)
19 Oct 2018 18:02Z <Zoffix> brrt: It's this commit that's causing it: github.com/MoarVM/MoarVM/commit/8f...2935ea61ea
brrt okay Zoffix
timotimo oh hey brrt 19:08
are you interested in checking this out?
brrt ohai timotimo
timotimo i'm just a little baffled by it
brrt i'm silenced in #moarvm :-(
well, to be honest, I can have a look, but I won't be doing much coding this evening
timotimo i have not yet been given privileges to op myself there
AlexDaniel brrt: fixed
brrt ty AlexDaniel :-)
timotimo OK, so the problem with that bug is: attaching anything in the way of debugging tools makes it go away
i tried strace and perf trace, though i have not tried perf record or rr record yet 19:09
additionally, i didn't reproduce it locally, though i think i might know how to do it
what's more, reverting the commit in question fixing the bug doesn't make much sense to me 19:10
brrt lol
timotimo first i thought maybe the spesh facts aren't being marked as required and so there's deopt trouble
but i do see code to do the marking
brrt what commit is the matter 19:11
the commit that Zoffix gave us?
timotimo yes
brrt hmmmmm 19:12
timotimo Zoffix, can you perhaps spin up that vm again?
brrt what do the JIT logs say?
eh, spesh logs, these days
timotimo 17th of august; i'd say there were still jit logs then
no, wait
that was last month
2 months ago
i really need to get the frickin list of month names to numbers and backwards into my bleepin' head 19:13

Zoffix brrt: timotimo still need me to spin up that VM? 19:34
timotimo if you do, i'll have another look at the bug, and maybe brrt can also have a look with, like, a shared tmux session or so 19:36
Zoffix brrt: timotimo ssh [email@hidden.address] 19:39
timotimo TYVM
Zoffix brrt: info on where's the code and whatnot here: colabti.org/irclogger/irclogger_log...10-19#l955 19:40
timotimo i don't like how fickle tests can be that try to run rakudo 19:47
when i want to instrument it with some stuff
actually, the precompilation attempts fail? 19:49
Zoffix: you didn't tell me that "rr" exists as an alias :D 19:55
i was trying to figure out why the F trying to record the perl6 process would give me "Tests: ...github.../" 19:56
Zoffix has no idea what "rr" is
timotimo it can record and replay and time-traveling-debug program execution 19:57
except it doesn't seem to run on the VM for some reason 19:58
20:00 lizmat joined, p6bannerbot sets mode: +v lizmat 20:02 brrt left
timotimo damn it, i can't even reproduce the bug on the VM now 20:02
Zoffix :| 20:04
Did you remember to declutter the precomp files?
timotimo i think i did it right, but perhaps not
can you connect as cpan@ and "tmux a" to get into my session?
Zoffix The test file has "my $*EXECUTABLE = "./perl6-m";" in it... Could that be affecting the non-reproduction of bug? 20:06
timotimo ah, i did that!
i threw it out just now
did you change something else? 20:07
Zoffix just ran declutter
timotimo regenerated the .rakudo.moarvm file?
i had some dumb debug output hacked in there %) 20:08
Zoffix Yeah
k, now I can repro the bug
cpan@temp-perl6-dev:~/R/rakudo$ declutter; t/fudgeandrun t/spec/S32-io/io-cathandle.t
with that
Zoffix afk
timotimo OK 20:09
I ... i can't reproduce it though 20:12
this bug is *really* slippery
Zoffix I can. You sure you're running `declutter` and the rest in ~/R/rakudo? 20:19
timotimo i think i am. you're not rm-ing the .precomp folder under t/spec/Packages or what it was?
packages not Packages
Zoffix declutter is aliased to `rm -fr */.precomp; rm -fr */*/.precomp; rm -fr */*/*/.precomp; rm -fr */*/*/*/.precomp' 20:20
So presumably yes I am
timotimo oh, ok 20:21
how do you decide whether you reproduced it?
the whole fudgeandrun takes 13 seconds at the moment, but the test i'm looking at in particular, the last one, runs in under a second 20:22
20s user time, 13.5 real time 20:23
Zoffix lemme measure
So after doing t/fudgeandrun so it gens the fudge file, I do `declutter; time ./perl6 t/spec/S32-io/io-cathandle.rakudo.moar` and get 9.864s while on perl6 I get it for 5.5 20:25
Less than 40s vs. 3s I had before but still visible diff. 20:26
timotimo it's not the bug any more where it just stands still for about 15 to 20 seconds for no discernable reason 20:27
that was what i was trying to hunt down
and that is gone
i'd say the other thing is "just" a performance regression
Zoffix FWIW, the other two blockers are far more important IMO. This is just a perf penalty in some arcane code on some machines, while others are clear regressions R#2400 and R#2355
synopsebot R#2400 [open]: github.com/rakudo/rakudo/issues/2400 [fudged tests committed][regression][⚠ blocker ⚠] Module Crane is failing tests on HEAD
R#2355 [open]: github.com/rakudo/rakudo/issues/2355 [SEGV][regression][⚠ blocker ⚠] Concurrency feature race/hyper sometimes failed with Supply
Zoffix I mean, if you have the skills to fix them 20:28
The R#2400 in particular. There's already a fix for a very similar bug, so presumably the new fix would be easy if you know that codepath
timotimo: so did you make some changes to get the bug to go away or did it just disappear randomly?
timotimo not exactly sure
i tried a lot of stuff to hook up diagnostics and tools and such, and that never gave me the hang 20:29
MasterDuke Zoffix: btw, i ran 2355 in a loop for a couple hours and couldn't repro
