Kaiepi the jvm takes well over half an hour to build on my openbsd machine but on my freebsd vps that's a quarter as powerful it takes only 5 minutes? what? 09:41
jnthn Maybe the openbsd w^x rules mean that its JIT doesn't run? :) 09:44
Kaiepi the jit should run, w^x is allowed on the partition i have it installed on
unless it's like the current moarvm port, which entirely disables the jit even though it would run if it were enabled 09:45
maybe it could just be a matter of hdd vs ssd
jnthn Could be that
But...that feels odd
Unless it swaps 09:46
Or if it swaps on any disk on the BSD machine
nine TBH I'd be very pleasently surprised if the JIT would be responsible for a 6x speedup 09:50

AlexDaniel wonders why * expands to the number of elements and not the index of the last element 20:08
cuz then * and *-1 for the endpoint do the same thing… 20:09
actually I'm not even sure if this commit is right github.com/rakudo/rakudo/commit/35...c2c0643d5a
I mean, yeah, it's kinda right because *-1 is useless anyway… 20:10

AlexDaniel I remember this issue github.com/jonathanstowe/RPi-Devic...us.pm#L164
I think we hit it before, like months ago?
# P6M Merging GLOBAL symbols failed: duplicate definition of symbol IO 20:35
I agree with the error, actually, but somehow it used to work
how come this commit triggers it is beyond me github.com/rakudo/rakudo/commit/84...c80bd6e53b
jnthn: thoughts? 20:36
I can fix the module, of course 20:37
but is that what we want?

jnthn AlexDaniel: Huh, that's very odd 20:40
Does getting rid of the X:: in the name of the exception that I introduced help matters?
It's lexical so it doesn't matter what it's called
But it still feels off 20:41
AlexDaniel jnthn: so you don't want me to change the module, right?

ugexe vrurg: MVM_SPESH_DISABLE=1 would be another one to try next time youre on windows vm 20:55
vrurg ugexe: this helps so far. 20:57
I'll let it run for at least 1000 times to make sure.
AlexDaniel vrurg++ 21:00
ugexe anyone have an idea what could cause a test called t\04-nativecall\04-pointers.t to fail on windows if spesh is enabled? 21:01
timotimo hm, bad assumptions in optimizations? maybe regarding aligning or something?
ugexe around 4-5 months back i stop seeing it (but maybe just coincidence since i stopped at 6 months, checking *most* red builds)
just looking at the appveyor output 21:02
jnthn AlexDaniel: Well, could try changing Test.pm6 :) 21:05
AlexDaniel ugexe: 04-pointers.t or 06-struct.t? 21:06
ugexe 06-struct.t
oh wait let me go over this again heh 21:07
AlexDaniel ugexe: which test triggers the segfault? this one? github.com/rakudo/rakudo/blob/c583...uct.t#L199 21:08
if it's a segfault at all
ugexe yeah i meant 06-struct.t
AlexDaniel maybe a golf of the issue can help figure it out? 21:09
ugexe its the test after that one
AlexDaniel vrurg: I think there's something wrong with this commit github.com/rakudo/rakudo/commit/3a...a604be6fcf 21:11

which sounds horrifying :)

but I think I'm done for today…
vrurg AlexDaniel: how did you get HTML::Entity to fail?

japhb timotimo: You're saying my WAT exists so that your case will DWIM? 22:36
timotimo potentially 22:37
japhb hmmm
I can see that
vrurg timotimo: your case is reasonable. But I wouldn't expect a container to be stored in a hash value. That's asking for troubles. 22:45
*in a pair value 22:46
timotimo you mean when created with the => operator? 22:48
vrurg timotimo: yes
m: my %h; my $foo = "a"; my $bar = 42; %h = $foo => $bar.VAR; $bar++; say %h
camelia {a => 43}
vrurg That what I'd expect to be more valid to achieve the same outcome.
jnthn m: my $x = 42; my $p = a => $x; $p.value = 99; say $x 22:49
camelia 99
jnthn I'm quite sure this was an intended feature
timotimo oh vrurg can i get you to do something terrible to the moarvm build system? 22:50
jnthn And it specified behavior
*is
vrurg timotimo: not sure I'd want to get into that. 22:51
timotimo bitbucket.org/wolfpld/tracy/src/master/ - i only want this (its C interface to be exact) to be usable in moarvm optionally 22:52
it's a cpp library
that's the issue
vrurg jnthn: Thanks, I checked for other possible variants, and no other valid solution for your case. So, it makes sense, though still somewhat unexpected. :) 22:53
jnthn vrurg: I forget the original motivation for this, alas; TimToady++ probably remembers :) 22:54
vrurg timotimo: the point is that I never looked inside moar's build. But if nobody else takes that I could try next week. 22:55
jnthn: I could guess: for timotimo's example with the loop, perhaps. 22:56
timotimo i'd be glad if you could
vrurg timotimo: ok, I'm exhausted after TPC yet and have my flight back tomorrow. So, just remind me next week, plese. Maybe make a ticket with the details? 22:57
timotimo don't worry, i had an exhausting today, too 23:01
first a far too early flight, then a nap and another couple hours of driving, then a suddenly dead desktop pc :)
vrurg BTW, while a few people here: is it possible that a Setty could be is-lazy somehow? github.com/rakudo/rakudo/pull/3013 23:03
jnthn vrurg: Well, not of the core ones would be...whether somebody could implement that role in a module and make it lazy is another matter, though generally we've only ever associated laziness with list-y things, not associative things. 23:05
*none of
timotimo listy things are easier to make lazy, because grabbing "one specific item" lets you know exactly where to go look, whereas a "foo" in a hash that's backed by a generator-like thing can take an arbitrary amount of time, up to infinity 23:07
though of course you could have a generator that just maps a key to a value rather than a function that spits out key/value pairs
BBL
vrurg Don't want extra performance lost on an unnecessary check. Would leave it like that.
*loss
jnthn Yeah, I'd say is-lazy isn't really applicable for associative things 23:08
vrurg Thanks!
Actually, that's more/less how I considered it too. 23:10
