raydiak grr modern browsers...close 2 tabs, free up a gig of ram :P 01:13
01:24 avuserow joined
raydiak apparently sandboxing everything is necessary these days so malicious coders can't harm your computer via websites, but running you out of cpu and ram until the whole system slows to an unusable crawl due to 1 ill-tempered script or plugin is still totally acceptable 01:24
geekosaur mm, browsers *try* to detect that these days 01:25
chrome seems pretty good at it of late
on os x at least
raydiak seems like it only offers to kill stuff for me if the process doesn't repond for like...half a minute plus...which by that point everything else is often going just as slow 01:29

Woodi morning #perl6 :) 06:34
raydiak good morning Woodi 06:44
adu good morning 06:45
raydiak \o adu
adu o/
raydiak adu: hopefully you don't need to worry about it often, but I added the "rakudobrew test" command I mentioned would have been helpful, just fyi 06:46
adu raydiak: :) 06:47
raydiak so instead of tracking down the dir and make spectest you can just 'rakudobrew test'
adu thanks, I'm sorry I suck at finding Makefiles
Woodi about current "modern" browsers: I moved back to firefox from chrome and looking for something better again... so many freezes. ~130Mb on start. just switching between 4 very plain pages makes it goes 10Mb more. IMO it's madness...
adu Woodi: me too, actually 06:48
Woodi and: new R* yay ! \o/
raydiak yeah browsers kinda irritate me, but then again a lot of modern software does 06:50
I have a computer that plays netflix but windows 7 solitare brings it to its knees 06:51
adu raydiak: I think the ideal browser would be something that JIT compiled a page to OpenVG would be kind of amazing 06:52
raydiak hmm maybe I'll switch to links... 06:53
adu I read a comparison of TUI browsers 06:54
kmandla.wordpress.com/2011/01/13/a...-browsers/
it's confusing because there are like 5 browsers that sound like "links" 06:55
some of them are forks
Woodi I remember there was some TUI browser with javascript, links ? 06:59
raydiak yeah I remember as a kid for a while my only access to the internet was the local library bbs that you could use lynx on
Woodi yea, even gopher was better then ftp :) 07:00

LLamaRider tadzik: I can't write a fork bomb if I can't write a fork :D 07:53
I'm also surprised you would hide it down in NativeCall, rather than have it as a low-level primitive in the p6 07:54
but this is handy, thanks :) 07:55
Timbus i think its being avoided because windows cannot do it 08:01
08:02 zakharyas joined
LLamaRider That's a fair point. perl5 just "faked" that somehow 08:06
raydiak emulated fork w/threads iirc 08:07
08:08 rurban left
LLamaRider what I know is that perl5 has one of the briefest cross-platform fork bombs 08:13

so I was just wondering how that would look in p6 :)

LLamaRider I am doing this wrong somehow
Timbus m: await { say 'test' } 08:31
camelia ( no output )
raydiak you have to pass await a promise, not a block
Timbus dunno why you think await takes a block 08:32
also, im pretty sure moarvm uses a threadpool, so its going to be more of a small pop, rather than an explosion 08:33
LLamaRider ah. because start{} takes a block. Wrong intuition
removing the {} doesn't change anything though 08:34
r: sub bomb { start { bomb; bomb; } }; await bomb; # fuse is wet, no boom

pmurias hi 11:33
yoleaux 09:24Z <nine> pmurias: Have never tried that so probably serializing Python objects doesn't work. I also don't like having to initialize Python at BEGIN time, but I create a Python class for every Perl class that inherits from a Python class. And that's a very BEGIN time thing to do.
11:34 jluis left
pmurias nine: the problem with doing things at BEGIN time is that the python objects will have to get serialized 11:34
if we precompile
11:36 sirdancealot left
nine pmurias: I'm currently trying to defer Python class creation to runtime. This may also fix very strange errors Python is giving me in t/inherit.t. Of course, like so often, Python's error message is less than helpful... 11:36
11:40 jluis joined
xfix By the way, what is the equivalent of flat_map from Ruby in Perl 6? .map.flat? In Ruby, [1, 2, 3].flat_map { |item| [item, item] } gives [1, 1, 2, 2, 3, 3] 11:40
pmurias the most significant problem is the we would have to load a python module twice 11:41
if we are doing precompilation
assuming we want to import python modules at runtime 11:44
nine pmurias: precompilation seems to be a difficult topic anyway. AFAIU I'd actually have to serialize the Python interpreter's (or Perl5 in case of Inline::Perl5) whole state to allow for precompiling modules that use Inline::Python and run Python code at compile time.
pmurias that seems problematic 11:47
but it would be great to have 'use Foo:from<python>' work at some point 11:48
Timbus m: say [1,2,3].map: { $^a, $^a }
camelia rakudo-moar 80b912: OUTPUT«1 1 2 2 3 3␤»
nine Is 'use Foo::from<>' implemented at all in Rakudo?
moritz nine: I'm pretty usre that's how java interop is done 11:49
nine I would love to play with that mechanism and see how far I come.
pmurias the precompilation barrier seems hard 11:50
* a hard problem
one possible solution would be to just create the python interpreter twice, at first just look what the python modules contain and create stubs which will then be filled at runtime 11:53

nine Dill also provides the capability to: save and load python interpreter sessions
Timbus m: my $a = [1]; $a ,= 2;
camelia ( no output ) 11:55
Timbus okay. guess i gotta update
moritz ok, perl6/doc has a slight problem 11:57
we have types int and Int
if I check in a file lib/type/int.pod alongside lib/type/Int.pm 11:58
pmurias nine: doing that with perl5 would be more problematic
moritz people on case-insensitive file systems would be unable to work with it anymore
pmurias serializing an open socket wouldn't be easy 11:59
Timbus m: my $a = [1]; say $a ,= 2; 12:00
camelia rakudo-moar 80b912: OUTPUT«Memory allocation failed; could not allocate 174080 bytes␤»
Timbus well okay
nine pmurias: before starting any work into that direction, we should think about real use cases for this functionality. I guess serializing open sockets is not possible with plain vanilla Perl 6 modules either. Precompilation is just about saving load time after all. 12:04

pmurias Perl 6 modules are written with precompilation in mind, Perl 5 aren't 12:09
nine Perl 6 modules may be written with precompilation in mind, Perl 5 can't.
pmurias and the python ones also assume that they are loaded at runtime 12:11
nine Authors with a Perl 5 background like me will not write modules with precompilation in mind until they are first bitten by precomp problems. And maybe not even then (again like me).
pmurias currently the way modules are loaded in rakudo sucks 12:12
but things will be precompiled automatically in the future 12:13
nine I cannot even find anything about precompilation in the synopsis.
pmurias with our current compilation speed we are heavily dependent on precompilation 12:15
12:16 FROGGS joined
pmurias by precompilation I mean compiling things in a different process then the thing that uses them 12:16
nine My current takeaway from this discussion is: avoid running Python/Perl5 code at compile time at any cost. 12:17
pmurias that seems like a sane strategy 12:18
12:18 kjs_ joined
nine Then I already have to thank you for bringing this to my attention when I can still do something about it :) 12:18
pmurias is it common for python modules to have side effects at load time? 12:21
nine I actually don't know. I'm actually not that familiar with the Python ecosystem. 12:22

lizmat pmurias: why would you want to export a class ?
moritz why not? 14:02
lizmat loading a module with a class already exposes it in the scope you do the -use- in
moritz that S11 link has an example for exporting an enum
lizmat: unless it's a lexical scope
there's nothing wrong with keeping classes lexical, and exporting them
pmurias how can you import them using require? 14:03
lizmat feels like an "our" vs "my" argument here, and I'm not seeing why I would want to use "our" here

By default, CompUnit.precomp will now *only* use whatever is in @*INC (by default) to set up the @*INC in the external process doing the precompilation.
This actually breaks a few spectests (and actually passes a todo test), but does not break panda (mostly because it doesn't use .precomp yet). Hopefully this will make it easier to trace some hard to find precomp related bugs and other oddness. If not, then please revert this one.		 16:54

hoelzro good morning, #perl6 17:41
17:42 Hor|zon left
moritz \o hoelzro 17:49
hoelzro I had a thought (well, a few, actually) over the last few days about earliest { ... }, and I wanted to post them here for some feedback 17:52
17:53 pecastro joined
hoelzro first of all, is there any reason that earliest and friends are limited to operating on Channels? I was thinking something like earliest * { more $socket { ... } ; more $channel { ... } } could be of use, since sockets also have a notion of being done, and receiving more information 17:53
17:53 Alina-malina joined
hoelzro second, I was thinking about the implementation of earliest, and how for multiple channels, it currently uses busy waiting; I was thinking of adding a new NQP op to make things more efficient, and wanted to see if others had thoughts on the matter 17:54
17:54 pmurias left
moritz hoelzro: IMHO earliest could work on Promise/Channel/Supply, and we should have a Socket -> Supply (or Channel) bridge 17:55
(becuase they have a very well-defined notion of "value available", and the Socket -> Supply bridge could define what counts as a value) 17:56
I can't comment on your second thought
17:57 denis_boyun_ joined
hoelzro moritz: that's true, but my concern with that is that if a thread is reading from a socket to pump values into a channel/supply/etc, another thread might be trying to write to that socket, for example, when a message is received from a channel 17:57
and I think thread safety of socket operations is OS dependent
you would definitely have to define what a "next value" of a socket is, though, yes 17:58
moritz hoelzro: well, the solution for thread safety thing is to have an owning thread, and communicate with that thread in some thread-safe manner 18:01
hoelzro right 18:02
so let's say I have an owning thread that manages my socket
moritz hoelzro: and if we don't have the primitives yet for doing that, we need to create them
hoelzro my thread has two tasks: read bytes from the socket, parse them into protocol-specific packets, and send those along a Supply 18:03
moritz or our high-level socket wrappers must do the locking
hoelzro the second task is to accept packets from another Channel and send them along the socket
18:04 denis_boyun_ left
hoelzro so my thread needs to block until data are available on the socket, or on the channel 18:04
so my idea for earliest accomplishes that, but there may be a better, "sixier" way
18:04 pecastro left
hoelzro moritz: I think, at least on MoarVM, the sockets are locked, because I can't write to a socket I'm trying to read from 18:05
18:07 isBEKaml joined
moritz hoelzro: maybe there should be an async-write which queues writes until the lock from reading is available 18:10
hoelzro ah, but the protocol I'm implementing (XMPP) expects a write at the beginning before sending any more data from the server, so that would deadlock, I think 18:11
18:12 FROGGS_ joined 18:15 Sqirrel left, FROGGS left
moritz then you shouldn't try to read before writing 18:20
hoelzro so right now I have a stanzas method, which returns a lazy list of stanza objects parsed from reads from the server 18:22
another thread is reading stanzas from that list, and is determining what stanza to send next to the server
if I wanted to prevent reading until writes are sent, I would have to wait for each stanza to be "handled" by invokers of stanzas 18:23
so it seems that perhaps my design is flawed

moritz hoelzro: I think exposing stanzas as a lazy list is dangerous, because it loses the information of which ones are read, and which ones aren't yet 19:10

it increments the state because the lhs has to get a value first before it gets hypered with eq 19:41

lizmat :-)
it's still not working like it should, though :-( 20:57
at least not on OS X
20:58 Vlavv joined
ugexe :delete'ing after precomp caught me off guard for doing something like something like: sub pc(*@modules) { CompUnit.new($_.path).precomp for @modules }; { temp %*ENV<RAKUDO_PRECOMP_WITH> = "$*CWD/lib"; pc('A.pm', 'B.pm'); } 21:05
i.e. $*CWD/lib is not in @INC for B.pm's precomp 21:06
lizmat ugexe: you should be able to pass the INC that you want using the :INC named param 21:07
and also: there are still dragons there :-( 21:08
thanks for also looking at this :-)
psch maybe TDD isn't that great of an idea - as soon as i start writing tests i find all kinds of bugs! 21:12
more seriously: i'm stuck with True and False specifically
21:13 LLamaRider left
lizmat you need a en.wikipedia.org/wiki/Ternary_computer 21:14
psch trying to differentiate between a type object and True or False on the java side seems not-quite-possible. Ops.istype doesn't work 'cause it sees the boxed java type, and Ops.istrue and Ops.isfalse evaluate as bool...
lizmat: maybe, yes. i'm afraid i'd just add another not-working case though :) 21:15
maybe i just did something wrong with istype...

lizmat the only thing with a ReentrantMutex REPR is Lock.pm

lizmat it states: $ perl6-p --ll-exception -It/spec/packages -e 'CompUnit.new("t/spec/packages/Example/A.pm").precomp.say' 21:42

which is odd, as apparently the -It/spec/packages is *not* on @*INC there 21:43
ugexe yeah same deal here. its not finding the required modules in @*INC (even though @*INC has the proper path) because it installs some modules but not others
lizmat however, checking @*INC[0], t/spec/packages *is* there 21:45
ugexe fwiw it happens if i dont use rakudo_precomp_with and use %*ENV<PERL6LIB> directly 21:46

I found out when I had a .moarvm around from another perl6 build 22:10

lizmat it failed with missing or wrong dependency then 22:10
hmmm...? there is no compiled version for C.pm now, and it still fails with missing REPR ? 22:11
22:13 sqirrel_ left
ugexe from what im seeing it *might* be related to roles. i say this because in a folder with multiple modules the only one it ends up compiling *doesnt* load any roles 22:16
then again it could just be a 'use' problem i suppose and they just all happen be be roles 22:17
lizmat you mean the usage of roles in the modules being compiled?
ah, yes
.oO( must read more carefully )
ugexe: that one module, does it have any 'use' command in it ? 22:18
ugexe no
and in a subfolder of *that* all of the modules get compiled (no 'use' statements) and in another subfolder they all fail (all have a 'use' statement) 22:19
lizmat I think *that* is the deciding factor :-)
ugexe yeah, getting ahead of myself heh 22:20

22:30 LLamaRider left
lizmat the plot thickens: on the JVM, if C.pm is not precomped, it correctly fails with: 22:34
When pre-compiling a module, its dependencies must be pre-compiled first.
Please pre-compile /Users/liz/Github/rakudo.jvm/t/spec/packages/Example/C.pm
after having precomped C.pm on JVM, trying to precomp A.pm fails with Missing serialize function for REPR ReentrantMutex 22:35
on parrot it works 22:37
so I guess we somehow have a live Lock object that is serialized, but cannot be deserialized 22:38
