psch roughly "LAST and NEXT work in p6for, but FIRST doesn't do anything. FIRST and NEXT work in while and loop, but LAST generates bad bytecode"

Don't take a hint when looking for a Code's $!do.

The desugared op p6for doesn't give us a Code but a Block here, which causes get_attribute_boxed called with a hint to not properly resolve to the right Attribute, and return a ContainerDescriptor. Not supplying a hint makes the lookup more costly but at least correct.
psch bartolin: ^^^ that fixes the FIRST issue at least, if somewhat bandaid-y 10:04

psch *not* a good day today /o\
the actual problem is that for Block (at least in that case) we don't actually set P6OpaqueBaseInstance.delegate, but instead shove the delegate into field_0 11:46

psch wonders if that hints strongly enough at "signature compilation will solve enough problem to try and tackle it now" 19:06
jnthn psch: I'd doubt that'd be the cause of a FIRST bug... 19:07
The sig comp would improve performance some though :)
psch jnthn: so the FIRST issue is... where? i mean, where do i look to see why there's a ContainerSpec with a delegate in field_0..? i'm really out of ideas :S 19:09
jnthn psch: That sounds more like there's a Scalar container in the way? 19:11
Or at some point we went ahead and accessed something via a hint (thinking we had one type) and ended up pulling something out of a Scalar 19:12
tcx.firstPhaserCodeBlock = codeObj.get_attribute_boxed(tc, 19:13
gcx.Code, "$!do", HINT_CODE_DO);
psch yeah, i tried tossing the hint there
jnthn If that were to be passed a Scalar instead, for example...
psch that leads to "no such attr"
jnthn Right, so that's probably the problem.
psch well, the problem is that codeObj isn't a sensible Block afaict
'cause in field_0 (which is $!do) it has the ContainerSpec with a Block as delegate 19:14
so building the Block is where it breaks, which is what made me think sig-comp
'cause #126493 has a similar problem - without decont it doesn't work on r-j
synopsebot6 Link: rt.perl.org/rt3//Public/Bug/Displa...?id=126493
psch although i'm not sure sig-comp is around at that level, which is probably Actions/World 19:15
jnthn If I had to guess, that one is more likely a missing decont somewhere in the signature binding code in github.com/rakudo/rakudo/blob/nom/...inder.java 19:16
psch ...now i'm confused 19:17
well, unless "that one" means the FIRST issue 19:18
jnthn psch: I meant signature binding related issues
The FIRST one doesn't seem likely to be about that.
Do you know exactly what type we do end up with where the attr bind fail occurs? 19:19
I think we set the debugtypename on the JVM also...
psch in the linked ticket?
i haven't look at that recently
the FIRST bug doesn't have any attr bind fail
jnthn No, the FIRST one where you got the error earlier today
psch it just does nothing... :)
jnthn gah, I'm confsued then :)
Which isn't surprising given I fell asleep while cooking dinner earlier... 19:20
psch that sounds a bit scary... :)
jnthn Baked potatoes are good at looking after themselves for a little while. :) 19:21
But yeah, I'm pretty exhausted.
psch alright. maybe stash the gist and look at it tomorrow again ;)
'cause as i said, i really don't have any idea where i should look there
the gist of what you said sounds reasonable - somehow there's a scalar where the CodeRef should be
jnthn Maybe after the assignemnt to tcx.firstPhaserCodeBlock, dump out the debug type name of what is assigned 19:22
I'd think it'd have to be going wrong there...since I don't immediately see a way p6takefirstflag could be wrong. 19:23
psch i think what comes in is already wrong, actually
gist.github.com/peschwa/4646440fc4...ck-txt-L21 19:24
that just doesn't seem right
as in, it's the SixModelObject codeObj for p6setfirstflag, which takes a Block
jnthn org.perl6.nqp.runtime.Ops.typeName(codeObj, tc) = "Block" 19:25
19:25 sortiz joined
jnthn I think typeName there has a decont in, so that may be misleading. 19:25
nine_ Now that I've vastly simplified the whole precomp store locking code....I run into a locking issue
psch ah, yeah, it does 19:26
jnthn So it's possible a decont of codeObj before trying to grab its $!do would "fix" it 19:27
But only "fix" because I just checked on MoarVM and we don't auto-decont on that op
psch uhm, where's debug name hanging off of again?
jnthn .st
psch debugName: null 19:28
jnthn o.O
...I wonder if I implemented serialize/deserialize of that on JVM when I added it.
Anyways, I'd try a decont of codeObj before calling get_attribute_boxed. 19:29
And if that "fixes" it, then take a look at where the container comes from... 19:30
Or rather, why we end up with it on the JVM but not on Moar
psch alright 19:32

rakudo/precomp-store-redesign: When $*REPO's identity (it's contents and all following repos) changed since we

rakudo/precomp-store-redesign: In case we can continue to use the precomp file, we now store the updated

timotimo ah, right
geekosaur someone should fix dalek to add 1s pauses after the first two lines to avoid flood kicks 20:50
RabidGravy I'm sure that never used to happen 20:56
does it need+v or somthing?
geekosaur pretty sure that's been happening all along. but there are timing things that affect whether freenode servers think it's flooding or not 20:59
that is, it's happening more often now but it has periodically happened the whole time I've seen dalek report commits 21:00
psch well, today dalek had a lot of commits with noticeably long commit messages
geekosaur +v does not affect flood kick; giving bots +v is just a convention to mark the official bots in a channel, because few channels use +v for its normal use 21:01
(moderated discussions; moderator has voice and grants +v to whoever currently has the floor)
(some channels use it to mark the folks who have ops without having them opped all the time, which freenode discourages) 21:02
(and in one project dev channel I'm in +v marks the folks with commit access to the project repo) 21:03
RabidGravy sure, but strangely it's only the "flood" here that gets it kicked, in #perl6 it has +v and no kicking 21:07
geekosaur be interesting to see which one it sends first. freenode may consider the union of those the flood, and it's doing #perl6 first and then when it gets here freenode says enough? 21:08
er, intersection I guess
I keep only noticing them after the fact so I can't see if dalek is already throttling (just not quite enough) or something 21:09
nine_ RabidGravy: it does get kicked in #perl6, too. 21:17
RabidGravy oh yeah, but it only gets kicked when it emits here 21:18
nine_ The problem is that dalek is connected to quite a lot of channels and the output pacing seems to be per channel and doesn't take into account that it's writing on other channels at the same time
That said, it does seem to be somewhat faster here

and yeah, moar does build pretty fast on hack 22:20
i'd guess like 90 seconds or so?
timotimo incidentally, wow, stracing it gives a *lot* of "clock get time realtime blah blah" system calls
it's ... done?
psch haha
that's what they call a heisenbug, right? :P 22:21
timotimo well, whenever you need to compile rakudo, let me know and i'll watch over it for you :D
psch haha
i'll readd my diag output
'cause that got tossed somewhen inbetween, apparently
now :S 22:22
22:24 raydiak joined
psch there it goes 22:26
that really stumps me
i mean, the diff has three &say calls with statement_mod:<if>
well, and &so calls too 22:27
does any of those call Any.map..?
timotimo OK, you got it to crash again? it was the OOM killer again this time 22:28
psch yup 22:29
hence my inquiry
timotimo well, *something* pushed hack to fill up its swap space completely
that's usually indicative of something having filled up all of the ram recently
you're not say-ing something inside of something that gets called by say, or .perl, or .gist or anything? :)
because that'll create frames on the heap at record pace
psch well, that's what i was asking above :P
gist.github.com/peschwa/86e06c4ca4...e1-txt-L30 is the diag code i'm using 22:30
i hope none of &say, &so and statement_mod:<if> call Any.map, cause that'd be somewhat weird
hm, i suppose &say could call c.map(*.gist)... 22:31
timotimo could potentially, yeah
psch yeah, it calls statement_mod:<for>, hence p6for, hence map
guess i'll nqp::say() instead
timotimo yeah, that's probably the right thing to do 22:32
it's going up again 22:37
8 and a half gig already
9 gig
goodbye moarvm process :)
psch oh ffs :< 22:38
that's just really weird though
'cause the very same patch compiles just fine on r-j
well, at least further than on r-m
timotimo :\ 22:41
jvm may have something clever for infinite recursions
psch now with block-if..!
sure, but even that shouldn't lead to a useful result, right? 22:42
timotimo right; i've no clue :<
psch i mean, the degenerate case of < sub f { f } > can never produce anything useful
timotimo yeah
it could be made asynchronous :D
psch ...i'm out of ideas 22:45
does if call map somehow..? o.o
timotimo it really shouldn't 22:46
gist.github.com/timo/0dfba0c72f065...5f5a021688 - does this seem worth having? :) 22:48
psch i'm not completely sure what i'm looking it 22:49
timotimo "top frames by size"
psch i mean, if the name column had the same values...
oh, so it's purposefully disjunct data
timotimo which frames are sticking around and how much memory they take
psch ...but why is it called "before" and "after"?
timotimo there's significant overlap 22:50
because i made a patch in between the files
in between the measurements*
the measurements themselves are at as-closely-as-possible the same point in execution of the same piece of code
