gfldex is there a maximum number of threads Rakudo is willing to spawn? 12:58
jnthn Depends precisely what you're asking. 12:59
You can call Thread.start({ }) until you run out of resources
Which then it's Rakudo's unwillingness :)
ThreadPoolScheduler, on the other hand, will do up to 64 by default
So if you have more than 64 cores and are CPU bound then a) I'm envious and b) you might want to increase it 13:00

AlexDaniel jnthn: by the way, there's tools/speedup.p6 tool that suggests unambiguous text descriptions for speed improvements 17:35

and yes it also round better :) 17:36

17:39 pmurias joined 17:40 p6bannerbot sets mode: +v pmurias
pmurias jnthn: yeah $_ being dynamic is super annoying to optimize, especially given that it is even declared when it's not used 17:44
AlexDaniel what about something like this:
m: for ^5 { say { $_ + 1 } … 5 }
camelia (1 2 3 4 5)
(2 3 4 5)
(3 4 5)
(4 5)
(5)
AlexDaniel is this behavior going to change? 17:45
stmuk AlexDaniel: I'm asking about the version of MoarVM not rakudo 17:49
AlexDaniel stmuk: ah, the one in NQP_REVISION and MOAR_REVISION 17:50
stmuk: but also I tend to bump before toasting, so it should be identical to master HEAD
timotimo AlexDaniel: that's just lexical, not dynamic
right?
stmuk AlexDaniel: thanks 17:51
pmurias does MoarVM use the truffle approach of being able to just assume stuff and when we see the assumption is actuall false being able to just throw away the assumption dependening code and deoptimizing? 17:57
AlexDaniel timotimo: yea I think you're right
pmurias so it would could a '$_ is never used as dynamic' assumption 17:58
timotimo yeah, that's the speculative optimizations we do 18:04
but just like the issue says, we'd have to throw away that particular assumption on any call to the outside 18:05
jnthn AlexDaniel: The usage you asked about is entirely lexical. A non-lexical one would involve CALLER:: or CALLERS:: or some such 18:15

and I've *just* had it on HEAD 19:49
and I've never seen something like this previously with that frequency
so, does it mean that a change in zef is triggering some rakudo bug?

jnthn AlexDaniel: Dunno, but if it's a MoarVM regression there's not that many commits on HEAD vs. the last toaster run 20:06
I see lots of new regressions :/ 20:07
AlexDaniel jnthn: but how can it be a moar regression if it happens on 2018.06? 20:27
that's the part that is confusing
jnthn Oh 20:28
I didn't know that, I thought it was a regression since the last time we toasted, and explained the new set of problems
AlexDaniel yeah, but it was toasted by Zoffix
now that I did it, I had to toast 2018.06 freshly 20:29
so my completely uneducated and random guess is that it's some change in zef that is making moar blow up 20:30
*and* it's not something that was fixed on HEAD, because I just had it with freshly installed rakudo and zef on whateverable server 20:31
statisfiable6: help 20:32
statisfiable6 AlexDaniel, Available stats: core (CORE.setting size), install (size of the installation), libmoar (libmoar.so size) # See wiki for more examples: github.com/perl6/whateverable/wiki/Statisfiable
AlexDaniel statisfiable6: core
statisfiable6 AlexDaniel, OK! Working on it…
AlexDaniel, gist.github.com/ec5ee979637aab3197...dc74410df5
AlexDaniel statisfiable6: install 20:33
statisfiable6 AlexDaniel, OK! Working on it…
jnthn The latest zef commit is "Make ecosystem updates and listings multithreaded" :)
AlexDaniel oh
jnthn: yeah I didn't have time to even take a look, lol
:D
jnthn So I'm guessing that yes, it tickles a bug 20:34
statisfiable6 AlexDaniel, gist.github.com/91926c67a4b61a3557...e04029fa48 20:36
jnthn Did you get to do a toast of HEAD yet?
AlexDaniel jnthn: yes: github.com/rakudo/rakudo/issues/2230
the ones with ✗ and no comment are likely regressions 20:37
statisfiable6: libmoar 20:38
statisfiable6 AlexDaniel, OK! Working on it…
AlexDaniel or something, I'm still going through the list 20:39
jnthn OK, but does the zef thing seem to happen at HEAD too?
AlexDaniel yes! 20:40
in fact I had it happen right in front of my eyes when installing deps for whateverable, not just in toaster
jnthn ah, ok
statisfiable6 AlexDaniel, gist.github.com/3c96c478ce60e3898e...95de8acc21 20:41
AlexDaniel also, this `zef` change seems to rely on `race`, which IIRC is much more broken on older rakudos
so e.g. someone having early-2017 rakudo from distro repos will not be able to use zef properly, I think 20:42
20:42 brrt left
jnthn Hm 20:43
And they'd not have a packaged zef?
I guess maybe not
AlexDaniel yeah, most distros don't have zef packaged

heh the commit message says “Speeds up `zef update` from 4.3s to 7.8s”

one of the test files segfaults semireliably
I just tested it on 2018.05 and there it doesn't 23:23
23:23 urdh6 left
AlexDaniel so something is going on and I should check it 23:23
one problem is that the module has 12 dependencies and most of them are not in perl6-all-modules :S
is there any easy way to tell zef to install a bunch of modules into a folder? 23:24
so that I can then have a single location to set PERL6LIB to?
jnthn I think there's some --to=
(But don't know the details, sorry) 23:25
AlexDaniel ok I tried `zef install --install-to=. JSON::Fast` and it created a bunch of folders with stuff 23:26
that's nice, but then?
jnthn Can you then put . in PERL6LIB and have it work? 23:28
AlexDaniel tried that, doesn't work
jnthn Hmm
What if it's --to=file#. if it allows that?
AlexDaniel no, I don't think so 23:31
but is there no way to point perl6 executable to a whole repository?
jnthn Does -Iinst#. or some such work? 23:35
iiuc, it's kind-of-repo#path
AlexDaniel jnthn: Yes!!!
jnthn :) 23:36

I should've figured it out earlier, will make my work so much easier
