MasterDuke skids++ bunch of rakudo and roast PRs recently
skids someone else will have to 'resolve' 124974, I get no option to reply/close in the RT UI on that one. 02:48
MasterDuke i have the resolve option, i'll resolve it now 02:50
done 02:51
samcv working on my monthly grant update, almost done 04:14
MasterDuke, looks like MVM_string_equal is the 5th most cpu usage of a mvm function 04:31
2.8% but let me see i think i can speed up that function by at least 50%
MasterDuke when doing what? 04:32
samcv compiling the setting
MasterDuke oh, nice!
samcv hmm it may already be fast hmm. i remember it being slower than my revised unicode one though
the unicmp that is
not sure if you read/heard about how i sped that up 04:33
MasterDuke i usually read that stuff, but i don't remember the details
samcv ok it doesn't seem to in my previous grant status update, hmm i may have done it since then. it was in my YAPC-EU presentation cry.nu/YAPC-EU-2017/MoarVM-Internals/#/ here are the sslides if you're niteresting 04:34
*ed
but i made a ring buffer that i used a grapheme iterator, and when i found a differing one i refered that ring buffer (the previous 3 graphemes) to the function. so you can unicmp a string that's 1000000's of graphemes long and it doesn't have to get the collation data for all but the last 3 before where it differs 04:35
pretty cool
MasterDuke good deal. i haven't read those yet, but i now have a tab opened for tomorrow 04:36
samcv cool
MasterDuke i'm off to sleep, later...

  AlexDaniel++ for spotting
synopsebot6 Link: rt.perl.org/rt3/Public/Bug/Display...?id=132006

Special-case FailGoal to adhere to S05 (Fix RT#130528)

  (...also, clean up whitespace debris produced during parsing)
   The general-case behavior of the rx ~ operator is correctly
   implemented, but it results in an internal variable name
   leaking, which contradicts an example in S05.
   This is an ugly fix, but doing it "right" would impact
   compile-time hot paths. This solution confines the mess
   entirely to the error handling path.		 07:02

nine Skarsnik: what does that do? 11:15
Skarsnik this PR github.com/rakudo/rakudo/pull/716 11:18
I am making mergable if one day someoine want to merge it x)
nine Skarsnik: I wonder, if we should rethink the whole NativeCall interface and make that available via use NativeCall :api<2>; 11:22
Skarsnik well it work along side the existing code
nine yes
Thanks to lexical module loading :) 11:23
This would be one of the prime use cases for that :)
Skarsnik but yeah NC/Test does not have a well defined version managment 11:24
a NC v2 for me will force the use of type called like c-int32 to avoid confusion with rakudo native type x) 11:25
nine what confusion?
Skarsnik the fact that int32 is VM native type and both a C 'native' type 11:26
nine But they are meant to be the same? 11:27
Skarsnik I mean it lead to confusion some time. int is native but not a good C native type for NC 11:28
Zoffix, hm where is the 6.d idea repo? 11:29
nine Skarsnik: I still kinda like the old idea of a way to avoid repetition like native-library 'foo' { sub foo() is native { * }; sub bar() is native { * }; } 11:34
Skarsnik well it will still work 11:35
I wonder if we could add stuff to list routine associated with a lib 11:36
Not sure what the use could be
can we get property of the block a routine is in ? 11:38
nine Well this is Perl 6. I guess there is a way to implement this :)
Skarsnik I have to admit that look like a neat syntax : native-lib 'foo' { all my def} 11:39
Zoffix huggable: 6.d 11:40
huggable Zoffix, Proposals for 6.d language: github.com/perl6/6.d-prep/blob/mas...EATURES.md
Zoffix Skarsnik: ^

[Coke] RT #132003 - this should probably be RFC not NYI (if NYI, should have a pointer to where we've said it's going to happen) 11:48

Skarsnik could be neat if we could write grammar for binary string 11:51
[Coke] AlexDaniel, thanks. 11:52
Zoffix I see some mentions of the speculations as reference for marking that ticket NYI: rt.perl.org/Public/Bug/Display.htm...xn-1486259 12:01

camelia 5===SORRY!5=== Error while compiling <tmp>?Adverb bytes not allowed on m?at <tmp>:1?------> 3say "?u" ~~ m:bytes / .**2 /7?5;?
nine I'm not sure grammars are the right tool for binary data. 12:03
Skarsnik hm 12:04
for like a dissambler it could be usefull?
nine Text formats where grammars shine are all about tokenization and deciding after each token what may come next. I don't know of any binary format that works this way.
Ok, maybe a disassembler is a good example :) 12:05
But what I more often see is some well defined format with data structures that may have some header word that tells us what structure it is. Also lot's of offsets in the byte stream (think image file header with the offset of the first data chunk) 12:06
Skarsnik not even sure what needed to make a keyword 'stuff' {} work. A trait on a block?
nine Parsing TCP headers is about "is this flag in byte 23 set?"
Really many binary formats can be better described by NativeCall's CStruct. Except that the latter implies some alignment. 12:08
Skarsnik m: multi sub trait_mod:<is>(Block $s, :$foo) { say 'foo'}; foo {}; 12:09

Zoffix m: class foo {}; sub infix:<is> (&s, foo) {say "foo"}; {;} is foo 12:14
camelia foo?
Zoffix {} is a Hash, not a Block, although even were you to fix that, that code won't work. 12:15
Skarsnik hm was there a named block syntax?
Zoffix m: my &foo = {say "foo"}; foo
camelia foo?
Zoffix (I only know of that one)
Skarsnik like to use with a goto 12:16
*should buy a perl 6 book*
Zoffix We don't got goto yet
Though we do have labels already
m: FOO: loop { loop { say "hi"; last FOO if $++ > 2 } }; say "outta here" 12:17
camelia hi?hi?hi?hi?outta here?
MasterDuke is it just me, or does this list of arguments ( github.com/rakudo/rakudo/blob/nom/...052-L10061 ) look wrong, considering this is the method signature ( github.com/rakudo/rakudo/blob/nom/...#L193-L201 )? 13:19
nine MasterDuke: assuming the QAST::SVal.new( :value('INTERPOLATE') ) is used to find the method, it looks fine to me? 13:23
Zoffix MasterDuke: yeah, especially considering the same QAST a few lines below doesn't have the extra int arg
MasterDuke Zoffix: yeah incorrect, or yeah agree with nine?
Zoffix extra int before the monkey stuff
MasterDuke: it looks wrong to me too 13:24
MasterDuke yep, that's what stuck out to me
Zoffix gah, git blame on that page killed my browser =( 13:25
MasterDuke heh, it takes a couple seconds on the command line 13:26
most of those lines are from 2013 or 2015
essentially an initial commit to add interpolate to P5 regexes, and then a single commit to add ignoremark support (which i think was done off-by-one) 13:27
Skarsnik git still cnfuse me o no end
git checkout -b switch branch?
MasterDuke that creates a branch and switches to it
nine -b is for a new branch
Zoffix: the last int is optional 13:28
Skarsnik duh
how it let me create a branch that exist
fuck this
MasterDuke nine: yeah, but the order of the first few seems wrong 13:29
the non-optional ones
Zoffix MasterDuke: well, now I'm unsure. is $<codeblock>.ast, the invocant or passed as \val?
Skarsnik best git command : rm -rf
Zoffix nine: assuming `int $monkey` gets value from QAST::IVal.new( :value(monkey_see_no_eval($/)) ) the code MasterDuke linked to has 4 values before the monkey line, while the same code block below has only 3 values. That makes me think at least one of them is wrong 13:31
Zoffix sees neither QAST::Regex nor QAST::NodeList in github.com/perl6/nqp/blob/master/d...t.markdown :( 13:33
Zoffix &
MasterDuke can also compare with P6 regex stuff around line 9848
which seem to match the 3 args before monkey, not the 4 13:34

timotimo crashing on a malloc? that doesn't make much sense unless the internal structures malloc uses have gotten busted 15:42
like a free list entry pointing at an incorrect location? 15:43
Skarsnik generally it's a bug somewhere else. from what I remember when I work with this 15:44
it crash on that : github.com/MoarVM/MoarVM/blob/mast...ay.c#L1155 (runing a perl6 -e '') 15:45
the malloc size is normal 15:46
hm
I don't remeber if efence is thread safe actually
MasterDuke Skarsnik: MVM_SPESH_DISABLE=1 should make it not use any threads at startup (i think) 15:49
timotimo aye, and if you have something multithreaded, you may be able to just my $*SCHEDULER = CurrentThreadScheduler.new(); 15:55

it run out of page to create

timotimo efence wastes memory left, right and center 15:59

Skarsnik echo 16553500 > /proc/sys/vm/max_map_count :) 16:01

AlexDaniel, can you try replacing the line 754 in nqp/MoarVM/src/core/nativecall.c with cptr = *((void **)((uintptr_t) storage + (uintptr_t) repr_data->struct_offsets[i])); 19:35
it does not crash anymore for me 19:36
but I am getting tired/strained on typing with one hand :(
AlexDaniel Skarsnik: er, maybe, I'm currently hacking on docs 19:51
so possibly tomorrow or later
Skarsnik I tried on a rakudo-2016.10 19:52
AlexDaniel Skarsnik: I've linked this discussion so that it's not lost rt.perl.org/Ticket/Display.html?id...xn-1486588 19:53
Skarsnik this look very likely it's the cause. if this + manage to generate a signed that goesback to -xxx it goes boom when trying to do a ptr with it 19:57
MasterDuke what's an example of something prohibited in regex interpolation unless `use MONKEY` is on? 20:39
samcv MasterDuke, how much speed increase did you get from changing things from index* to eqat* in INTERPOLATE? 21:09
oh and previously you also changed it from a while loop and ordbaseat/other things into the proper ops 21:13
MasterDuke samcv: i didn't measure it directly, but didn't really notice any speedup 21:19
the index*->eqat* changes would probably slow it down, but index* was wrong 21:21
samcv wait why would eqat be slower than index 21:22
MasterDuke checks at every position
samcv isn't that what index does? 21:23
.o( eventually i want to have knuth morris pratt on ignoremark and ignore case as well. that will be sweet )
for index* that is
MasterDuke but there's the overhead of the INTERPOLATE each time
instead of just once (for index) 21:24
samcv well you changed it from index to eqat in the exact same location so that should be faster 21:25
maybe i'm missing something 21:27
MasterDuke i'll explain in a couple min
samcv kk 21:28
MasterDuke ok. so INTERPOLATE is called for each position in the haystack until there's a match 21:38
samcv just noticed a point where a user could overflow the stack. doesn't appear to crash it though
MasterDuke this used to be done via the loop+ordbaseat, is now done via eqat 21:39
i accidentally used index
samcv ah ok
MasterDuke which would be faster (since it does the whole walk each position in C, instead of via successive INTERPOLATE calls) 21:40
but is wrong, since the needle could change at each INTERPOLATE call
(in some situations)
samcv oh wait nvm wasn't triggering it properly 21:41
with how i changed getting the property values, i allocate a string onto the stack. just realized if some malicious user requested a property value string that was larger than the stack 21:43
then you'd get a SIGSEGV. so gonna put bounds on it
MasterDuke heh, yeah, that shouldn't be allowed 21:46
samcv like it is super unlikely anyone would do it. but safety is good
anywhere you're allocating onto the stack or into memory with user input
oh MasterDuke i thought you might like this article llewellynfalco.blogspot.com/2016/02...gn-in.html 22:06
on how to get clairity in conditionals and consistency. i've adopted its suggestions and it's made the conditionals i write clearer and more consistent 22:07
and faster to read and understand quickly
interestingly the bottom function is 1.5x faster than the top one, testing it only for numbers under 1000 gist.github.com/77c241e6d25c035213...30c6011a01 22:26
i'm curious how that compiles
or numbers under 100 even 22:27
