brokenchicken What it means is a LTA error for whatever problem your code has :) 00:00
(or a bug)
jdv79 its happening on a p5 sub call in my app but i can't golf it yet 00:02
in isolation is works fine
*it
brokenchicken *shrug* I only see it mentioned in World in symbol lookup: github.com/rakudo/rakudo/blob/nom/....nqp#L3927 in Actions on EXPORT sub: github.com/rakudo/rakudo/blob/nom/....nqp#L5719 and as a method defined on stash 00:04
Run with --ll-exception it should give better stacktrace
Is it called a stacktrace or a backtrace?
brokenchicken goes to play Witcher 2 for a bit :)
jdv79 ah ha 00:12
something to do with having use XML; and use XML::Entites:from<Perl5> in the same scope 00:13
shouldn't that work?
brokenchicken Yeah, but there are a couple of bugs that involve stuff like that doing wrong things 00:15
jdv79 nine: ^^^
i guess i'll bug it
well, i unfortunately need to do that:(
brokenchicken Like rt.perl.org/Ticket/Display.html?id...et-history and rt.perl.org/Ticket/Display.html?id...et-history and rt.perl.org/Ticket/Display.html?id...et-history and rt.perl.org/Ticket/Display.html?id...et-history 00:16
XML is just a type object right, you don't need any subs or anything? Don't know if it'll help, but maybe try `use XML` in a separate file and then do constant XXML is export = XML; 00:17
And then in the file with XML::Entities, you won't have XML:: namespace
(I'm just making shit up as I go along, I've no idea if this would work :P) 00:18
jdv79 well, XML does export sbus 00:21
subs
from-xml() for instance
brokenchicken ok, same stuff 00:22
constant &something-or-other = &from-xml; but that's buggy too, so do something like our $whatever is export = &from-xml; or sub whatever(|c) is export { from-xml |c } 00:23
or sub EXPORT { { '&from-xml' => &from-xml } } 00:24
jdv79 can i just use XML somewhere else and just call XML::from-xml()? 00:25
that seems to not work either
brokenchicken You'd be able to call that only from where you used it... and only if those subs are `our` subs 00:26
jdv79 oh right 00:27
brokenchicken: your 2nd to last suggestion seems to wokr! 00:30
work even
thanks
brokenchicken w00t! 00:31

BenGoldberg Inline::Perl5 is purportedly designed to work in a thread safe manner. 02:31
If you are getting segfaults, then either something is wrong with Inline::Perl5, or something is wrong with the specific perl5 module you are using. 02:32

kenietz when i run an external process with shell it runs ok and the program waits until the external process finishes. but if i capture stderr and stdout with :err and :out the program does not wait the external process 06:12
is there a way to run external process, capture STDERR and STOUT and yet the main program waits till the process finishes? 06:14
so far i could not find any info about it. not in documenation not on the net 06:15
06:16 cdg left
TimToady well, someone has to put the output somewhere 06:19
geekosaur kenietz, that situation is typically called a deadlock
TimToady the program could produce gigabytes of output, and you can't the system to buffer it all up for you
*can't expect
kenietz i see. 06:20
so i should read it and put it somewhere but not the screen :) 06:21
geekosaur to one or more files, usually 06:22
TimToady that's the usual practice, if you want to wait till it's done 06:25

github.com/samcv/UCD/commit/48588c...e7efebcR36
err wait, so it's cause i'm calling it asking for different folders. maybe could just leave it my, not much performance change 06:38
or just make the state variable a hash or something indexed with the folders i want to store the files 06:39

nine jdv79: quite ironically Inline::Perl5 didn't survive merging of lexical_module_load quite as well as I thought it would. I'm in the process of rewriting the part that creates wrapper classes but $dayjob leaves me quite drained lately :/ 07:19

jmb2041 In any event, someone may know the simple answer to this -- I am archiving all news stories associated with Trump and I use LWP::UserAgent to get those stories. nytimes ends in an endless redirect (example: www.nytimes.com/2017/01/24/us/poli...rump.html) but works when using wget -qO- ... could this be related to the user agent string?
samcv yes that likely could. can you see the headers and compare them between wget 07:20
and LWP::UserAgent
what useragent are you using?
jmb2041 $ua->agent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36"); 07:21
I went and got the user agent of my version of chrome and just used that
nine jmb2041: try using wget's user agent
samcv yeah maybe it thinks you're trying to be sneaky
nine jmb2041: looks like they permit access to robots so they show up in search engines but require normal users to log in
samcv i like how NYT has free access to historical news articles. that is super awesome 07:22
jmb2041 is there another header besides user agent that specifies something as a robot?
nine jmb2041: no
samcv well. there are clever methods of detection 07:23
but mostly the answer is no
jmb2041 I sort of cheated in my script and said if LWP fails to end up with 200, to just do "my $output = `wget -qO- $url`;" ... but that's not ideal. So I'll try finding the user agent of wget
samcv cloudflare is sometimes annoying as hell. i have an IRC bot that grabs url titles. and cloudflare wouldn't let me first grab the header, and then if the bot deemed the page text to grab the rest of the page 07:24
ended up having to parse the headers and the page content together to work around that and make my own url title grabber
also it bails as soon as it gets the title
so doesn't have to grab the whole page
nine User-Agent: Wget/1.18 (linux-gnu) 07:25
jmb2041 In a perfect universe, there would be an API for all of this from all the major news providers -- it still doesn't solve actually extracting the article out of the HTML, which one has to write a different parser for each one until it breaks from an update on their end

You give it JSON documents and it indexes everything for you
samcv ah
and where is this stored 07:36
jmb2041 I purchased 256GB of ram to hold all the documents (3 billion+)
It's on my server
samcv ah ok 07:37
nice!
jmb2041 For instance, if you wanted to see all the comments made recently about Perl 6, this would be the endpoint: apiv2.pushshift.io/reddit/comment/...erl%206%22
it gives a JSON response, so you will probably want a JSON prettifier (but I should probably eventually just prettify it from the server at the expense of a few extra bytes)

cschwenz as %INC no longer exists in Perl6, is it even possible to unload a loaded module? (my use case is i need to force a recompile of a module) 14:10

mst jnthn: did nine's work on lexical 'use' land yet?
14:14 sammers left
jnthn mst: Yes 14:14
mst cschwenz: so, 'use' is now (correctly) lexical, so you can basically load the modules within a scope, and 'reload' by loading it again within a new scope, I think 14:15
cschwenz mst: okay, will try that… :-)
mst whether this 100% works yet I've no idea though, since I've not previously encountered anybody except me who was crazy enough to want to do this and I haven't got round to trying yet 14:16
cschwenz :-D
jnthn Would have to check with nine but my first guess is that's not sufficient, since use = need + import, need being the level you're trying to invalidate for a "reload" mechanism, but all of the lexicality falls under the import part.
brokenchicken don't work for me 14:17
jnthn Somehow you'd also need to trick it into thinking it was loading a new version of the module
perlpilot Isn't there a "manual" way to compile a module?
jnthn There's probably some neat way to make that happen with a CompUnitRepo implementation.
mst well, I'm assuming if it needs recompiling it's now a different CU so far as the CUR is concerned 14:18
jnthn Yeah
mst so in *theory* this should be doable
cschwenz would something as simple as changing ":ver<0.1.1>" to ":ver<0.1.2>" trigger a recompile? 14:19
jnthn I don't know how much of my original design for this stuff survives; I kinda handed it off. But originally there was a delegation model, which I believe is retained, so if you stuck something at the head of the chain with an "invalidate now" switch it may be able to stick a fresh downstream chain in place that thinks nothing was loaded yet.
jnthn waves hands :)

jnthn lizmat: constants are our-scoped by default so end up as global symbols in the module 14:25
lizmat: Since nine's lexical import changes, those too are brought in as lexicals 14:26
So the conflict is legit.
lizmat so anything our scoped is exported ?
jnthn It's just the same as if you have a class Foo { } in the module and do a my class Foo { } when importing
Sure
brokenchicken So you don't even need an is export on subs just make them `our`?

samcv what do people think of this so far. can i say which compiliers have different levels of support? 20:07
brokenchicken "Additionally, in Rakudo blead and in the next monthly release of Perl 6 these names are all now case-insensitive:" <--- this is not exactly accurate. Perl 6 releases are 6.c, 6.d, 6.etc language release. There aren't any monthly Perl 6 releases. It's Rakudo compiler that gets released (and for regular users they aren't even monthly, as they get them from Rakudo Star). But IMO we shouldn't mention such minute 20:11
implementation details in the docs, as they are for Perl 6 language and not for just a particular implementation. Once we have infrastructure, we'll be marking stuff that got support in 6.d, 6.e, etc, but for now we kinda just document what is the latest and greatest.

samcv commas are fine for delimiting the names i think 20:21
and there's other standards i can't remember that use commas 20:22
idk tho do people really think semi colon would be good there?
brokenchicken samcv: what about names that have commas in them? Won't that confuse users when they try to use the name with commas and perl tells them it's an invalid char?
Like a bunch of ZWS stuff. Are there any standard names for them? 20:23
samcv yeah the ones in those unicode files
but I think it's fine just to leave out the commas
they don't have any syntactic meaning

agentzh This is Rakudo version 2017.01 built on MoarVM version 2017.01

thanks for the info.
brokenchicken timotimo: weird. Maybe just new travi's "trusty beta"? The other day I pushed a commit in the evening and travis bot said it passed THE NEXT DAY when I was at work
timotimo yeah, very trusty indeed. 22:22
agentzh: wow. the optimizer isn't supposed to be that slow
well, if it constant-folds something for you that is cpu-intensive to calculate, that'll take a bunch of time, of course 22:23
but that same time isn't spent during runtime
agentzh with optimization turned off, my whole 4.3K LOC p6 project compiles in 24.687s with .precomp/ removed.
this is a pretty fast machine (macbook pro 15 inch mid-2015 with the configs maxed out). 22:24

camelia rakudo-moar 0ad05c: OUTPUT«(timeout)»
agentzh seems like compilation time is a major issue when developing relatively large p6 projects. 22:27

agentzh anyway, i'll keep --optimize=off to avoid any potential surprises during my own development. 22:29

i've got 8 logical cores here.
22:31 pecastro joined
brokenchicken Don't think so 22:32
agentzh ok
22:32 sena_kun joined
gfldex technically yes, but it's still very unstable 22:33
brokenchicken agentzh: it's worth noting that a few months back, I was running coverage reported on Rakudo compiled without the optimizer and spectests would occasionally flap, even though on optimized version they didn't. So, if you start getting weird errors, try with optimizer turned on :)
Oh right, cause you can manually tell it what to compile right?
And you could have some sort of build script launcher running in multiple threads precompiling what it can in parallel, and then shooting off the main script that would find everything precompiled already 22:34
gfldex you create a .p6 file per module and a Makefile with the rules
then you run make -j6
brokenchicken intersting
Wonder if there's anything that can be cooked up with the CUR api
agentzh brokenchicken: that makes sense, the default settings should be mostly exercised one. 22:35
gfldex: i still need to figure out the topological order right?
gfldex yes
agentzh gfldex: any tool that i can use directly for that?
gfldex but a Makefile can do that for you
and it wouldn't be hard to find the use statements in modules and generate the Makefile 22:36
agentzh gfldex: *nod*
will try.
gfldex agentzh: there will be
agentzh will write a simple p5 script to generate the makefile snippet. 22:37
since i have so many .pm6 files
brokenchicken there's RAKUDO_MODULE_DEBUG env var you can turn on and it'll probably give you enough sequential info to figure out some sort of topoligical info?
agentzh manual writing the makefile would be too tedious and error prone :)
gfldex that's one of the things I want to do with meta6-bin
agentzh brokenchicken: interesting. will check it out. 22:38
gfldex: nice
brokenchicken: that's very useful :) 22:39
thanks!
gfldex: thanks for the makefile tip!
sena_kun there are quite a lot of dd usage occurences in docs now, about 150 sentences(+/-20). I assume that almost all of them(except for debugging-related page) should be replaced with something else? 22:40
brokenchicken shrugs 22:41
gfldex rechnically yes but in some cases that would be quite tricky 22:42
and it would reduce readability in many cases
brokenchicken If it's so persistent at staying, perhaps it's worth keeping it and just go with the flow, until we actually encounter problems due to its presence. It *is* documented as rakudo only debug thing. 22:43
gfldex i would also expect quite a few modules in the ecosystem to sport dd
