MasterDuke sauvin: reproducibly? 01:17
sauvin Finding out. 01:18
Yes.
MasterDuke, error given is: *** Error in `/usr/local/bin/moar': malloc(): memory corruption: 0x00007fe5dc0fea00 *** 01:19
MasterDuke can you post the code that causes it?
sauvin termbin.com/8tn6 01:20
That's the start of it, that's the end of it, and everything in between. What's on port 5000 is raw log output from my IRC client.
It had gone 1525051060 when it barfed. 01:21
(1525051060 lines of input, that is)
MasterDuke is it that line in particular? or is it just going that number of lines? 01:23
i.e., can you pull out a specific strings/byte sequence that causes it 01:24
sauvin Probably not. It's live input. 01:25
MasterDuke ah, not saved off anywhere? 01:26
TEttinger I know some clients/fonts have had issue with this string, but I doubt anyone here will have an issue 01:27

sauvin Let's see if it crashes the code I just posted, TEttinger. Can you do that again, please? 01:28

sauvin Nope, it's still running.
TEttinger I'm pretty sure the issue was client side with one client side font
sauvin What I'm wondering is if I'm smashing a stack or something.
TEttinger so that is good news for me, your test confirms that it isn't a unicode thing for me 01:29
MasterDuke sauvin: what version of perl6 are you running?
sauvin This is Rakudo Star version 2018.01 built on MoarVM version 2018.01
implementing Perl 6.c.
01:30 DataLinkDroid left
sauvin TEttinger, that string went through HexChat, got piped out through a socket to an ncat process to which the code I termbinned connects. 01:31
01:32 mcmillhj joined
TEttinger I think I can eke the info I need from the guy who had the problem. we both use the Floe IRC client and Floe has some spotty WPF-based text rendering. that many-language text probably forces a bunch of fonts to be used 01:32
I use unifont, which means i never have to switch except for emoji
sauvin I was just amazed to see core being dumped. I've not seen that in YEARS. 01:33
Is the code I termbinned stack-intensive or something, do you think? 01:35
TEttinger over 1.5 billion lines.. 01:37
wow

sauvin Another thing I'm wondering about, though: how does input jump from just a few thousand to a billion and a half in such a short time? In the past half hour, I've only gotten some 5k lines of input (with CPU% and MEM% staying down to something like one or two percent). A billion and a half is more like a whole day's traffic, so, *something* is confused. 02:53
Another logging process, one that actually commits the lines to a disk file, has me having only 265038 lines over the past twenty four hours or so. 02:55

Clarify 'Bar.pm6' vs 'how to use Bar.pm6'		 03:15
sauvin OK, here's one mystery solved. It wasn't 1.5 billion lines. That was the timestamp field. It's not printing the line number for all the lines, it's sometimes neglecting to print the line number for whole BATCHES of lines. 03:17
03:18 comborico1611 left
sauvin This implies to me the possibility it's not printing all the LINES. 03:19

MasterDuke hm, i don't think you're printing per line, just per "chunk" of input 03:27
sauvin How is defined then a "chunk"? It's *mostly* printing lines of variable size.
03:29 eliasr left
sauvin Another core dump. This time, at 885 lines, followed by a *crapload* of unnumbered lines. 03:29
Maybe the input is just coming in too fast?

synopsebot Link: doc.perl6.org/language/module-packages
MasterDuke sauvin: fwiw, i don't know much about react/promises/Async/etc. might be good to ping timotimo, jnthn, Zoffix 03:35
sauvin Think I'm going to. I don't know perl6 nearly well enough to even guess at what that code is doing, exactly. 03:36
MasterDuke sauvin: you can add a `.lines` to the .Supply and then you'll get line by line printing 03:43
and you said you don't get memory growth? huh, for me, mem use grows really quickly and the OOM killer gets it 03:46
sauvin how are you getting your input? 03:47
MasterDuke `yes | netcat -l -p 5000 127.0.0.1`
got through 81350 lines (with .lines added onto the .Supply) 03:49
sauvin hm. no, i saw no appreciable rise in memory while i was watching it.
adding .lines seems to make it crash faster. 03:51
MasterDuke i need to get some sleep, but could you create an issue here github.com/rakudo/rakudo/issues ? 03:53
sauvin this 'malloc(): memory corruption' thing is a bit worrisome.
when i finish eating, i'll poke at that. 03:54
MasterDuke AlexDaniel: you'd probably be more help than i ^^^
AlexDaniel hello :)
sauvin hey 03:55
MasterDuke sauvin: fwiw, a new rakudo star should be released soon, might help
sauvin can't remember offhand how i installed this one! 03:56
MasterDuke what os?
sauvin ubuntu 16.04
MasterDuke huggable: debs
huggable MasterDuke, CentOS, Debian, Fedora and Ubuntu Rakudo packages: github.com/nxadm/rakudo-pkg/releases
MasterDuke you can find the monthly compiler releases there 03:57
sauvin tkink i went to a rakudo web site
MasterDuke but i do really need to go, good luck
sauvin night! 03:58
AlexDaniel sauvin: I'm trying to follow the discussion, are you still using .Supply(…) instead of .Supply(…).lines ? 04:01
ah, ok, got to that point :) 04:02
if it's crashing, that's bad, it shouldn't
but there were many (possibly related) fixes during these months 04:03
sauvin Yeah, no idea what's going on. Crashing after a few thousand lines, and not printing all the line numbers for whole batches of lines.
AlexDaniel sauvin: what if you set MVM_SPESH_DISABLE=1 env variable? 04:04
it'll make stuff slower, but let's see if it crashes
04:05 wamba left
AlexDaniel (ok that sounded a bit inaccurate, the env variable is of course MVM_SPESH_DISABLE, set it to 1) 04:05
sauvin Did that, finished eating, running to see what happens. Did away with .lines, using ++$n again. 04:06
Might be a while. Doesn't seem to be very predictable how long it'll run before it yarks. 04:07
AlexDaniel I would have expected this to print the lines correctly: whenever .Supply(:enc("utf8-c8")).lines -> $v { printf "%d ", ++$n; $v.print; } 04:09
if it doesn't then maybe there's something weird going on
sauvin It didn't.
There were whole BATCHES of lines printed without line numbers. 04:10
Where it usually seems to happen is during what I call a '354' event, where hexchat issues a "who ##channel" and a whole listing of user nicks, idents, accounts, servers, gecos and suchlike is returned. Some of those channel listings are over two thousand lines long, and they come down the pipe almost all in the same millisecond. 04:12
Think I'll launch a second process redirecting stdout to see if I can spot any other patterns. 04:16
AlexDaniel sauvin: yeah, would be great to have a test set for reproducing the issue 04:19
even if it's a lot of data
sauvin Oh, it'll be a crapload, but since some of the content is a bit sensitive, thinking some other means of coming up with test data is needed.
AlexDaniel with a way to reproduce it I'd be able to tell if the problem exists on HEAD, and in seconds we'll know which commit fixed it (or if it's a regression that is not fixed, we'll see what broke it) 04:20
sauvin I was surprised at what MasterDuke said, that just doing a yes | netcat smashed it.
AlexDaniel oh
AlexDaniel tries it
04:21 skids left
sauvin I'm not seeing increases in memory usage, which makes me fear it's a stack or queue of some kind being overwhelmed. 04:23
Another crash. Launching it again, this time with .lines put back in. Wonder if that'll make all the lines number. 04:25
04:27 AlexDaniel left, AlexDaniel joined
AlexDaniel uh, had to wait for my system to unfreeze :) 04:28
cono looks like a mem leak. It works fine until memory runs out, tried this piece: termbin.com/8tn6 04:31
memory increases very fast
with `yes | nc -l -p 5000`
sauvin That's what the error returned suggests to me. Malloc errors aren't something I'd ever had much luck chasing down even while I was still able to code in C. 04:32
cono sauvin: what OS ?
sauvin Ubuntu 16.04, distro-supplied kernel and libc. 04:33
cono do you have any messages about "OOM" in kernel log? 04:34
sauvin How do I view a kernel log?
If it's /var/log/kern.log, no, nothing. 04:35
AlexDaniel this works for reproducing the leak: yes | pv -L 30m | netcat -l -p 5000 127.0.0.1
(in a controllable way, 30m for 30 MiB/s 04:36
)
sauvin I actually found a legitimate bug? Usually, when crap blows up on me like this, it's because I'm an idiot.
AlexDaniel sauvin: yes 04:37
sauvin Go me!
That's a first for me.
AlexDaniel oooooooh, interesting… 04:38
sauvin ..?
AlexDaniel I stop `yes` and the script still keeps going printing lines 04:39
but the memory usage is no longer growing!
so it indeed stuffs the data somewhere before giving the chunks I think 04:40
sauvin: what's the size of your input? 04:42
sauvin So maybe something is getting stuffed into a tube faster than it can be pushed back out.
AlexDaniel oh wait, you have live stuff coming in? What's the bitrate? :)
sauvin AlexDaniel, for what I was doing, there's no actual "size". I have a hexchat script that relays everything it sees in raw IRC format to an ncat "server" that broadcasts it to anything connected to port 5000. It's live input. 04:43
AlexDaniel hmm
sauvin So, "bitrate" may not be particularly relevant. Sometimes it's half a goddamn novel in just a few seconds, followed by a few minutes of maybe a dozen lines a minute. 04:44
AlexDaniel anyway, please report your findings in a ticket :)
sauvin: if that crashes, maybe it's a separate problem
sauvin At the link that MasterDuke provided?
AlexDaniel but we'll see

You do a lot of changes, so when something goes wrong it's more likely to be you :) The actual issue is that we are unable to detect these bugs reliably, and the issue on i386 is actually my fault because it took just a little bit of communication with El_Che to make sure that similar issues will never happen, so I should've arranged that earlier 13:20

jnthn Zoffix: run_alt is also a method name in QRegex::NFA in NQP 14:35
Zoffix doh
jnthn I wonder if this relates to the precomp issue?
Zoffix I grepped rakudo's sauce but didn't grep NQP/MoarVM's
pmurias [Coke]: what's Tax IT? 14:36
Zoffix sjn: try blowing .precomp folders
stmuk: uh, pl6anet.org/drop/rakudo-star-2018.04-RC1.tar.gz is a 404 14:39
Or is it a test to see how many people test RC candidates? :)
stmuk Zoffix: yes its being replaced within mins by a RC2 with an updated zef (it would have been secs if not for an unfortunate typo)
Zoffix Ah 14:40
[Coke]: I don't know. I wasn't trying to fix that issue. "Basically, there are several places in the code where we are assuming something is a Str, when in fact it's a Pod object." ... Yeah, that sounds a lot like the problems I fixed and I did remove the Promise.allof stuff 14:42
That stuff is now handled by &textify-guts multies

mcmillhj Is there a built-in function that does something similar to all { } @list from Perl5's List::Util?

comborico1611 there are some comment in the documents 15:38
:) seems like I am wrong
comborico1611 Thanks! 15:40
timotimo mcmillhj: depending on what's in your block, there's different ways
mcmillhj: but you'll probably lik Junctions for this
araraloren and docs.perl6.org/syntax/$_ here mentioned /regex/
would work on $_
timotimo you can get an "all" junction with @list.all and then do stuff with it like method calls, operations, comparisons, and at the end coerce it to bool to do the actual "all true?" thing 15:41
m: my @words = <hello gold mold build>; say so @words.all.substr(*-2, 1) eq "l" 15:42
camelia True
timotimo "do all these words have an l as the second-to-last character
" for example
mcmillhj: does that help?
m: my @words = <hello gold mold build>; say @words.all.substr(*-3, 2)
camelia all(ll, ol, ol, il)
timotimo ^- helpful to see what's actually in the junction at any point in the calculation 15:43
mcmillhj timotimo: I'll check out junctions, but basically the behavior I was looking for was something like (1, 2, 3).all({ $_ < 5 }); # True (only returns True once). 15:45
timotimo: I also don't see .all on the List docs, is it defined on a different type ?
timotimo docs.perl6.org/routine/all 15:46
docs.perl6.org/type/Junction - this is more interesting
your code would just be "so (1, 2, 3).all < 5"
m: say so (1, 2, 3).all < 5; say so (1, 2, 3, 99).all < 5
camelia True
False
mcmillhj That returns more than a single result 15:47
15:47 Ven`` joined
timotimo you need to boolify it with "so" 15:47
or with if/unless
mcmillhj oooh, interesting 15:48
that builds off the Junction concept correcT?

mcmillhj I'll post the surrounding code, I wasn't sure if that was needed

mcmillhj Yes, I am using a List as a tuple here. 18:54

timotimo no fun allowed
comborico1611 lol
Zoffix tobs: ^ another way for your power-of-two thing
TimToady no, I started in a language with GOSUB
comborico1611 And it used the term subroutine? 19:59
TimToady that's what SUB was short for
comborico1611 Well that solves that mystery. Thanks!
TimToady 'sides, subroutines aren't functions in the mathematical sense
if I'd gone with Pascal, I'd've used 'proc', not 'fun' 20:00
comborico1611 I see. "subroutine" may have faired better if it dropped the "sub" part. "subroutine" is a mouth-full compared to function. 20:01
TimToady it's okay to pronounce "sub" as "function" :)
20:03 Ven`` left
comborico1611 I pronounce "methods" as member-functions. :) I hate that term method. 20:03
These terms such a learning curve for beginners. 20:04
Voldenet imho function implies mathematical semantics (state passed as an input) and subroutine does not
TimToady thinks 'member-function' is about one word too many for a common term 20:05
20:05 Zoffix left
TimToady and that's why we call them "graphemes", not the long phrase the Unicode consortium uses that I can't even remember 20:06
