5540083 6.7M -rw-r--r--. 1 timo timo 6.7M Mar 17 01:04 heap-1458173085.41926.json
where did i put the fixed version of json_xs? :\ 00:06
i don't *really* understand what the heap snapshot exactly contains here 00:07
but i'm now getting output, so that's good 00:08
i wonder if i should already turn references into the string heap into strings at json-dump-time 00:10
i kind of fear i b0rked the to-json-ification somehow 00:13
nope, at least the regular timing/allocation profiler is still fine 00:16
i can probably get away with replacing ; and , with the right kind of stuff to get a more structure-y thing 00:18
it's probably enough to change ; into "," and it'll be cooler 00:23
splitting the string by ";" takes a very long time. i'm considering implementing a role that i can plop on the string to tell the json dumper that it's supposed to be included verbatim without escaping in the final json output and just use subst there 00:32
nqp is making my life difficult right nw 00:53
i'm being dumb, subst always wants a regex, but i gave it a string instead

i don't think so
hoelzro wow, what happened? not feeling well?
timotimo yeah
hoelzro =(
timotimo well, i'm feeling better now :)
hoelzro oh, good!
timotimo just now digging into jnthn's heap profiler stuff 01:39
hoelzro I should probably dive into the heap at sometime as well =)
timotimo hah, what? :) 01:40
hoelzro heh, bad pun =)
jnthn's work looks pretty handy
timotimo i feel quite a bit relieved that we have #p6dev now; i can get away with not backlogging all of #perl6 now
hoelzro tell me about it!
timotimo i didn't expect i'd feel so good about the split so soon already
hoelzro it's surprising 01:41
well, not entirely, I suppose
it makes me feel a ton better when I push a lot of commits =) 01:42
'caus now dalek doesn't dump them in #perl6
timotimo ah 01:43
i didn't feel bad about making dalek output lots of stuff in the past
i thought everybody appreciates a slew of commit reports by dalek
hoelzro pushed a bunch of commits, and there was much rejoicing
hoelzro it's nice to know that people are working, and what they're working on =) 01:44
timotimo :)
the description of the "references" part of the snapshot isn't entirely clear to me :\ 01:52
it only makes sense to me if it only tracks how a thing gets referenced, but not by what 01:59
so my first idea of making one graphviz image that shows all interconnections won't fly, apparently? 02:00
every collectable in the "collectables" has a pointer into the "references" list and a "length"

lizmat looking at [Tux] test-t timings, I cannot help but wonder what I did yesterday that caused the slowdown :-(
because none of that work had anything todo with CSV afaik 08:34
[Tux] 13.8 -> 14.0 isn't that much of a slowdown, is it?
lizmat except maybe make the core bigger ?
it's a small increment (yet again)

RabidGravy how can I find why something is segfaulting in moar/reprs/CStruct.get_int 08:56

lizmat .tell jnthn it looks like I can have a "multi foo" in a role in the settings without having to specify a proto (see 2a20197) 12:28
.tell jnthn it works, I'm just surprised that it can and if it points to some kind of bug lurking somewhere 12:29
timotimo i think that's a known limitation of the core setting
lizmat yes, I know you must
timotimo well, it could be that if the role is applied after the core setting is through, it's fine?
lizmat it's just that I forgot, and it didn't complain
ah, perhaps that's it... I thought I'd mention it just in case :-) 12:30
timotimo how big is the optimization in the intarray.STORE(Range) case?
i'm so used to your commit messages having those numbers in them
lizmat the intarray.STORE case was about 30% 12:31
the strarray.join was about 10x faster, the intarray.join about 5x faster

timotimo ah, blobs could become value types, eh?
lizmat feels to me since Blob's are immutable, it should be a value type, indeed :-) 12:35
hoelzro o/ #p6dev 12:44
timotimo: have you thought about making that code you wrote last night into a proper module?
timotimo yeah 12:45
i'm also thinking to make it not json 12:46
because it's really not structured at all
if it was just lines with a keyword in front, that'd be a lot faster to parse, and would easily allow "parallelization"
moritz timotimo: Blob is a role, and mutable objects to the Blob role 13:02
and blob happens to pun into a class as well
timotimo oh
well, we can surely detect self.WHAT eqv Blob, no? 13:03
well, i suppose Blob.^make_pun? or Blob.^pun? which one is the one i mean?
moritz or we could give Blob a WHICH method, and then override it again in Buf 13:04
which sounds cleaner than messing with make_pun
timotimo hoelzro: the module might land in moarvm/tools or so 13:14

lizmat jnthn: do you think a SHA1 of a Blob would be sufficiently unique for a .WHICH ? 13:20
jnthn Hm, is Blob listed as a value type? :) 13:23
It's a...bit risky :)
lizmat jnthn: well, it *is* supposed to be immutable ?
Buf.WHICH would not change
from the current behaviour

jnthn lizmat: We'll break things for anyone who was putting blobs in object hashes if we change it...though that may be "not man" 13:24
lizmat: I more meant does S02 list it as a value type though
lizmat ah, lemme check
timotimo it would break things? i think i'm confused 13:25
jnthn timotimo: If you put them in relying on reference identity, then suddenly those that had value identity started being the same key... 13:26
timotimo ah
so a 6.d thing potentially
with the upgrade path of using Buf where Blob was currently used for that 13:27
lizmat jnthn: Blob is not listed as a mutable
timotimo well, not mutable has got to be the case, but does it mention "value type" anywhere? 13:28
that'd be what tips the user off to reference vs value identity, as jnthn just explained to me
perlpilot Blob is in the list after S02:1415
"Objects with these types behave like values"
timotimo ah! fantastic 13:29
lizmat perlpilot++
timotimo so giving Blob the WHICH would be a fix, not a change :)
lizmat eh, yeah, that was my thought :-)
jnthn OK, then +1
I was pretty sure S02 made a call on it :) 13:30
And I mostly prefer to delegate to TimToady's thinking there rather than doing my own ;)

Give Blob a .WHICH fitting for a value type

While Buf.WHICH remains the same, since that is a mutable type.
Please note that it was not an option to have a .WHICH attribute frozen in a $!which, as array type REPR's don't allow attributes.
lizmat $ 6 'Blob.new(1,2,3,4).WHICH.say'

timotimo we could probably implement a version of nqp::sha1 that operates on lists of integers 13:56
so there'd not be a need for a join there
lizmat timotimo: that would be excellent 13:57
perlpilot timotimo was reading my mind
lizmat at least the Blob.join got 2x faster recently :-)
timotimo it'd have to be clever in order to be easily equal-able 13:58
it's possible that we wouldn't actually gain very much over what self.join already does
lizmat sometimes however, I think we need to get rid of .WHICH as a string 13:59
but instead have something like .ACCEPTS (.EQUIV ?) that would allow being smarter about equivalence checking
jnthn ObjAt needs to become something smarter, I guess
nine timotimo: shouldn't blobs be well blobs of memory, IOW perfectly useable as input for SHA1 already?
jnthn It being a string is very much a stop-gab
*gap 14:00
timotimo nine: yeah, it'd be possible to run it directly on the blob
we don't have to support WHICH being equal across runs of perl6, right?
