colomon it's sort of cheating, because it gets there without having a bunch of things that are pretty essential for actual p6 coding. 00:22
whoops, lost context on that.... was commenting about how many tests were passing in rakudo-jvm 00:23
00:23 SmokeMachine left
colomon and was planning on following up by saying how awesome the progress was anywhere. 00:23
*anyway
00:23 SmokeMachine joined
colomon may have to shut up before he says more silly things 00:24
sorear huh. if I'm reading JVMS §4.10.1.9 correctly, it's possible to catch an exception thrown by a constructor, and then *use the new half-initialized object anyway*
colomon doesn't that defeat the purpose of throwing the exception? 00:25
colomon should really track down why his $work code is always output analytic curves, even when the flag says "Don't", before he starts playing more with Rakudo JVM 00:27
sorear holomorphic curves? 00:28
colomon no, simple 3d ones
well, up to NURBS
00:29 abnorman left 00:34 ecocode left
benabik sorear: 4.10.1.9 seems to be instruction verification? IS this mentioned under the new op? 00:37
sorear benabik: no, under invokespecial 00:39
benabik: note that the unitnitialized(42)->java/whatever rewrite is done BOTH for the normal termination output frame, and the exception output frame 00:40
00:42 Guest1337 left
benabik sorear: It _seems_ like there's a flag to say it's not usable in that case: see the small print at the end of the op. 00:42
sorear benabik: that only covers the case of calling a superclass/same class constructor from within a constructor 00:44
it doesn't cover the object construction case
new/dup/invokespecial
or rather, new/dup/astore/try{invokespecial}/catch{aload; mess around}/ 00:45
00:47 lelf` joined 00:48 skids joined 00:49 btyler joined
jnthn found enforcing the constructor call somewhat curious. 00:50
At least invokespecial is non-virtual...
00:50 lelf left
jnthn So it's trivial to optimize away empty ones. 00:50
(for the JVM)
sorear I'd rather get rid of new and unininitialized types and just have invokespecial return the new object on the stack like a sane op 00:56
jnthn: well, apparently there were some classes that used constructors to enforce security checks... 00:58
00:59 benabik left
sorear jnthn: btw, I'm going to attempt to write a class splitter in O(days), so we have it before we need it 00:59
colomon class splitter? 01:01
sorear colomon: produce a .jar containing several class files
colomon wouldn't that be a class joiner? 01:02
sorear colomon: class files are limited to 65535 entries in the constant pool and the setting already uses more than half of those
colomon oh
silly java
sorear there's room for optimizing our constant table usage, but only to a point: each method must have a unique name*, which must be stored in the constant pool 01:04
* technically we can use overloading to bend the limit, but there's a separate limit of 65535 methods which makes that less useful 01:05
jnthn sorear: Feel free, though there are probably more pressing things. 01:06
But -Ofun :)
sorear: If you want to figure out pipe form of open, that'd be a useful one.
sorear: The tests that use Test::Util to call out to perl6 block on that.
And you probably are cluefuller on that than I. :) 01:07

02:59 Guest1337 joined, woosley1 joined 03:06 shinobicl_ joined
shinobicl_ hi 03:06
colomon o/ 03:08
shinobicl_ is anyone familiarized with AspectJ? 03:09
colomon not I 03:10
shinobicl_ ok, an example... lets say that i have 10 classes, objects that have a method "persist" that saves the object to the database
and i want to add logging capabilities to each "persist" method 03:11
i just program an "aspect" and then i wire the execution of each method "persist" to this logging aspect 03:12
so aspectj detects when each "persist" method runs and can inspect the method, the object, the class, etc... using introspection 03:13
you can even inject new methods and attributes (sorta like perl6 roles) to the objects
and.. that is. at least these are the parts that i've used of Aspectj 03:15
the thing is, is a damn good idea. they call these problems like logging "cross cutting concerns". tipically janitorial tasks that your system must perform. With aspectj, you can take them "out of the way" of the design of system you are building. 03:16
03:19 SamuraiJack joined
shinobicl_ i guess that is totally possible to implement in perl6, and in a much better way. aspectj has its own issues that makes you shoot you in the foot many times. 03:20
moritz iirc jnthn implemented some aspect-oriented programming in one of his talks on the MOP 03:22
sorear colomon: find the relevant line in src/vm/jvm/QAST/Compiler.nqp and add a :tc adverb 03:24
colomon sorear: thanks!
JimmyZ shinobicl_: jnthn.net/papers/2012-gpw-meta-programming.pdf
shinobicl_ thanks JimmyZ. Already reading it. Grammar:Tracer, right? 03:26
colomon sorear: rand_I's randomness looks a little dodgy to me?
JimmyZ shinobicl_: nope, next that 03:27
colomon sorear: making good progress towards srand, I think 03:28
sorear: probably go to bed first, though.
03:29 daniel-s_ left
colomon nothing like learning Java programming while working on a compiler written in it... ;) 03:31
03:32 daniel-s_ joined
sorear I hear it's even better to learn a language by writing a bootstrapped compiler. 03:34
will look at rand_I
Stefans-MacBook-Air:rakudo-jvm sorear$ ./perl6 -e '{ my %h; %h{$_}++ for (^5).roll(1000); say %h }' 03:37
("3" => 128, "2" => 242, "1" => 260, "0" => 237, "4" => 133).hash
Stefans-MacBook-Air:rakudo-jvm sorear$ ./perl6 -e '{ my %h; %h{$_}++ for (^5).roll(10000); say %h }'
===SORRY!===
java.lang.StackOverflowError 03:38
colomon yup, not that random
sorear the first test is inconclusive, the second is *clearly wrong* 03:39
colomon do you understand why the stack overflow? 03:40
sorear Stefans-MacBook-Air:rakudo-jvm sorear$ ./perl6 -e 'my @h; my int $i; while $i < 100000 { @h[nqp::rand_I(5, Int)]++; $i = $i+1; }; say @h'
24875 25063 24986 12539 12537
colomon: no, I don't
rand_I would be good enough if the bitLength() were changed to bitLength() + 32 03:41
colomon I guess I can fix rand_I the same way we (I?) did it in Niecza -- just keep on rand-ing till we get a number that matches the constraints.
sorear would still not be uniform exactly, but the statistical difference would be small enough that you'd need to run an expirment for millions of years to detect thje difference 03:42
colomon unless you have a better suggestion
next question: why is srand returning a value in parrakudo?
sorear ...or use rejection sampling, that works too
because it predates Nil? 03:43
colomon yeah, that sort of makes sense 03:48
sorear thinks that the best RNG for many applications on current CPUs is AES-CTR 03:49
colomon java.lang.NoSuchMethodError: org.perl6.nqp.runtime.Ops.srand(J)J 03:51
what's that (J)J mean?
"The point of the function is to "seed" the rand function so that rand can produce a different sequence each time you run your program. When called with a parameter, srand uses that for the seed; otherwise it (semi-)randomly chooses a seed. In either case, starting with Perl 5.14, it returns the seed. " 03:52
sorear takes one argument of type long, returns a long
colomon should be taking two args, long and ThreadContext 03:53
sorear docs.oracle.com/javase/specs/jvms/s...jvms-4.3.3
colomon QAST::OperationsJAST.map_classlib_core_op('srand', $TYPE_OPS, 'srand', [$RT_INT], $RT_INT, :tc);
03:53 daniel-s_ left
sorear that only applies to newly-compiled code 03:53
03:53 preflex_ joined, ChanServ sets mode: +v preflex_
colomon sorear: eh? 03:53
sorear you often have to keep old versions of ops around for the benefit of src/vm/jvm/stage0/*.class
colomon oh 03:54
sorear I've taken to marking things /*FOR_STAGE0*/ when that's the only reason they stick around
btw, that link convers method descriptor interpretation
colomon ah, srand used to be in the QAST thing without an actual implementation 03:55
03:55 preflex left
sorear so you'll be able to make sense of (JLorg/perl6/nqp/runtime/ThreadContext;)J or whatever else gets thrown at you 03:55
oh
03:55 preflex_ is now known as preflex
colomon sorear++ 03:55
sorear ...did you recompile?
colomon ...yes
should I not have? or do I need to do something more? 03:57
sorear do you get the srand error when trying to compile code that uses srand? 03:59
with that map_classlib_core_op you posted, if it's saved and compiled, nqp ought to be generating code which looks for (long,ThreadContext) 04:01
not (long)
colomon I got that trying to run code that uses srand 04:03
(after my normal recompile) 04:04
(normal recompile: in nqp, make install; in rakudo-jvm, perl ConfigureJVM.pl and then make)
colomon is probably doing something stupid because he is too tired to program 04:05
errr... rebuilt everything the exact same way as I thought I did it before, and now it all works. 04:07
I have a working srand here; I'll check it over and commit it once I've had some sleep. 04:08
thanks, sorear++
[Coke] categorizes the java aborts: gist.github.com/coke/5879701 04:14
sorear [Coke]: did you see my test_summary patch earlier today? 04:15
[Coke] to bin/rakudo.jvm.sh -? already applied it. Thanks! 04:19
definitely a huge improvement! 04:22
sorear [Coke]: no, the later one
[Coke]: I modified test-summary to be able to process rakudo_test_run.tar.gz files generated by the spectest harness 04:23
[Coke] the "shell" stuff jnthn mentioned is blocking 165 tests.
sorear [Coke]: so it's now possible to do TEST_JOBS=4 make rakudo_test_run.tar.gz; t/spec/test_summary rakudo.jvm --archive rakudo_test_run.tar.gz 04:24
[Coke] sorear: does it change the default behavior or take an option for that? (checking)
04:24 xilo left
sorear adds option 04:24
[Coke]: if you, I dunno, have multiple cores and want a faster test summary

Woodi backtracking here ? 07:45
so it works as required ? 07:46
sorear \d\d? would work better
Woodi heh
sorear \d?\d (in a :ratchet context) means try to match a \d. whether or not you succeed, match another 07:47
Woodi works for me :)
sorear \d\d? means match a \d, then try to match another
Woodi it's misleading... 07:48

lizmat good *, #perl6! 08:58
moritz \o * 08:59
lizmat wrt irclog.perlgeek.de/perl6/2013-06-28#i_7266026 : the meta information in pod is only used to *select* a compunit, it is *not* needed during compilation
so it *will* be possible to trivially skip pod parsing as a speed tweak 09:00
meta information in pod is of course also needed when installing a compunit
09:03 xinming left, domidumont left 09:04 domidumont joined
FROGGS_ depending on the implementation it might be needed only when installing 09:04
09:04 xinming joined
lizmat oops, yes, that's actually what I meant: the meta-information from pod is somehow stored in a database on installation, and *that* is used to select the compunit 09:09
FROGGS++ for pointing out the ambiguity of my not yet awake brane
FROGGS_ I really like that pod section... we just need to convince TimToady++ a bit more :o) 09:10
moritz I thought pod blocks are accessible at run time?
FROGGS_ moritz: they are
but you dont *have to* care what is in this particular one when you have located the unit-file 09:11
you can, of course
moritz what is "the unit-file"?
FROGGS_ Foo.pm
(because module has more than one meaning)
moritz is this about speed-parsing to find whether a given file contains the module we're looking for? 09:12
FROGGS_ yes and no
if we implement it right we wont parse every module file and then sort them out by the pod blocks
09:13 xinming left
FROGGS_ when should have built a database when installing a module 09:13
09:15 xinming joined
lizmat and actually, that part of the code I have already written more or less 09:19
moritz is still lost, but that's OK
FROGGS_ moritz: np, we take you with us :o)
lizmat currently, the CompUnitRepo module's interface is TBD 09:20
but I think it will have an "install" method
09:20 FROGGS[mobile] left
lizmat and a "find" method 09:21
sorear is doing a thing
lizmat the "install" method will take a string, parse its contents for pod meta-info, and then put the string somewhere
sorear i've hacked the test harness to make a log of which blocks are used while executing which test files 09:22
moritz "install" and "find" sound like they should go into diffrent classes
sorear my hope is that we'll find that 90% of the test files use 10% of the setting
and then maybe we can do some cool demand loading thing to improve cold start performance 09:23
lizmat while recording the meta-information in some for somewhere if needed (this is not true for the proposed CompUnitRepo::Local::File)
moritz (unless 'install' is "add to repo")
lizmat install is add to repo
please note, this does not do any dependency checking or whatever 09:24
this is the final step of installing a compunit in a repo
and that repo can be just a directory/subdirectory, for development situation, just like @*INC now works 09:25
and then the filesystem just needs to be able to support the quirks of the compunit naming it gets thrown at it
(which would be the CompUnitRepo::Local::File class doing the installing) 09:26
or it could be something more elaborate that would do filename mangling and store meta-information in some kind of database (probably just some text file) 09:27
which would be CompUnitRepo::Local::Installation in my proposal 09:28
or anybody could make a different module with the same API
using a SQLite database backend for storing compunits and their meta-information
or even one that doesn't actually install, but fetches files from the cloud at runtime and *then* store them locally 09:29
or whatever, it is intended to be flexible
FROGGS_ sorear: what do you mean by "blocks"? 09:32
code sections of the compiler or the script?
because knowing dead sections of the compiler code is a pretty cool thing 09:33
sorear FROGGS_: I'm recording all of them, but I only care about the compiler and setting ones
FROGGS_ that is pretty awesome
because if an else block will never be used there is potentially a thinko/bug... but I guess you already know that :P 09:34
sorear I hadn't even considered the test coverage angle 09:35
My main objective here is to cut down on the 6 second startup time by allowing rarely used parts of the compiler and CORE.setting to be demand-loaded
FROGGS_ cool 09:36
sorear++
sorear If this works at all. 09:37
09:37 xinming left 09:40 xinming joined
FROGGS_ ohh, I'm pretty sure that you can get this done :o) 09:43
sorear: will this be available through a --target then? 09:44
like we already have --target=profile or so
sorear now I have a 1.6 Mline, 130 MB USAGELOG file 09:45
to parse it!
FROGGS_: not unless I can come up with a sane factoring
right now this is one-off experimental coding 09:46
FROGGS_ ahh, I see
wenn, maybe once it works we can use fudge turn switch in on/off.... 09:47

jnthn sorear: Did CodeRef get changed yet to not resolve all of it's annotations until first usage? 10:10
jnthn remembers thinking of doing that, but didn't actually get to it himself... :) 10:11
BTW, friendly reminder to those going to YAPC::EU: tomorrow is last YAPC::EU talk submission day. :) 10:12
And I don't see that many Perl 6 submissions :P 10:13
sorear jnthn: we can't even create a coderef until we have an annotation, because that's how we distinguish coderefs from other blocks 10:16
jnthn: i've been toying with the idea of resurrecting getCodeRefs, possibly in a different form 10:17
also then I can kick the non-hot blocks out of the core class and demand-load them 10:18
jnthn sorear: Yes, we have to get the annotation itself, but not all of the various fields out of it.
sorear: This is assuming the individual values carry some cost to create/are built on-demand...dunno if htat's acutlaly the case.
sorear jnthn: I don't think that makes a difference
jnthn: the generated methods for the annotation don't even show up on the profile, while getAnnotation does and fairly high 10:19
so I think it's doing all the work upfront

dalek ast: de39835 | (Solomon Foster)++ | S32-num/rand.t:
Add simple test of random number distribution.

Rakudo JVM currently has a bug where rand_I is biased towards numbers at the beginning of a range. This simple check should detect that by rolling a number from 0 to 4, then summing up the number of times 3 or 4 was found. In a proper random number generator, this should be on the order of 400. We check to see if it is less than 300 and complain if it is.
This might happened by change to a good random number generator occasionally, of course.		 11:26

FROGGS[mobile] Hehe 12:58
13:12 Chillance joined 13:16 tomyan joined
timotimo so, to implement dir(), the parrot backend gets the full list of contents and then lazily iterates over them in nqp code; can i easily do such a lazy iteration in java code, or should i add a jvm-specific nqp::dircontents and implement the filtering and lazyness in the dir method instead? 13:16
jnthn Well, if you expose it as opendir/readdir/closedir nqp ops then I guess you can get some laziness 13:18
But I'm not sure it's worth it
Maybe for really huge directory listings it would be...
13:19 benabik left
jnthn looks through the [Coke]++ list of Java aborts 13:20
timotimo so, am i allowed to make up a new nqp op name, even if it isn't available on parrot? or perhaps i could mimic the op on parrot because it already non-lazily gets all the dirs, too ...
FROGGS jnthn: I have dirs at work that have several thousands of files... 13:21
and it would be nice if it wouldnt takes several seconds to get the content as it is now using p5 13:22
jnthn timotimo: Well, you could add an nqp:: op for it, map it on Parrot to what it currently does, then implement it for JVM also, then have the same code in Rakudo...
timotimo: But FROGGS makes a good point. 13:23
We have an opportunity to do it righter than p5, it sounds.
FROGGS yeah, for example if you want to get the first file that matches a pattern, then you dont need the full list 13:24
timotimo hm, not sure how i have to handle the encoding; on parrot it does pir::trans_encoding__Ssi($filename, find_encoding__Is('utf8')) do i have to do something in particular on the jvm to get that same behavior out?
okay, i can use the DirectoryStream<Path> thing from java; i could create such an object with nqp::opendir, destroy it in nqp::closedir and iterate one entry with nqp::nextdir or something
but where do i keep the actual DirectoryStream instance? 13:25
13:25 benabik joined
jnthn timotimo: We already have an IOHandle REPR, potentially you can use that and stash a DirectoryStream in it too... 13:25
timotimo looks 13:26
jnthn A whole load of these fails pertain to a fiddly BS issue... 13:27

FROGGS well, pushing things this way to a junction can be useful I imagine 13:35
but I have to get into it first... I'm still a P5 hacker using P6
jnthn :) 13:36
Yeah, I tend to experience the opposite now: I'm a P6 hacker who sometimes uses P5 and has to think about it a bit :)
colomon same here. :) 13:37
FROGGS .tell masak I am working on v5's pack/unpack right now, we obviously need the intsize there too... I am thinking of providing %Config<intsize>, which defaults to 4, and can be overridden by setting %Config and by the precision argument to sprintf
yoleaux FROGGS: I'll pass your message to masak.
timotimo jnthn: did you mean for me to add a new field for a DirectoryStream to the IOHandleInstance class? do i have to do a magic dance for nqp to work with the resulting new repr?
FROGGS .tell masak I'm not sure if this can be passed to the "i" (un)pack token somehow 13:38
yoleaux FROGGS: I'll pass your message to masak.
13:39 FROGGS_ left
jnthn timotimo: No magic dance, I shoudln't think :) 13:45
timotimo OK 13:46
how should i signal "the end of the directory has been reached" from nextfiledir if i decided to return a String from it? (also, should i call it *_s in that case?) 13:52
oh, String can be null. 13:53
13:54 tomyan left
jnthn that works, yes 13:54
timotimo DirectoryStream has no explicit close thingie, so setting ioh.dirstrm = null should suffice to get it closed, yes? 13:55
oh, nope, it inherits closable.
jnthn Suspect it wants an explicit close...
timotimo indeed, and i've done that now :) 13:56
er, but how do i make sure that the directory stream gets closed if i have dir be lazy? i can't know if the iterator was thrown away, can i? 13:57
jnthn Hmm 13:58
That is the downside of laziness. The handle won't get freed until the object is collected.
And the finalizer runs.
timotimo should i write a TODO in the ops file and be done with it for now? 13:59
jnthn If somebody iterates all the way then it'll hit the end and know to close, I guess.
It's just if they stop in the middle.
timotimo yes
should i make nqp::nextfiledir close the stream when the iterator hits the end?
probably not, if nqp::closedir is its own op 14:00
jnthn No, just make sure that when that returns a null then the calling code uses closedir, I think.
timotimo if i my Str $foo := nqp::nextfiledir and the java function returns null, how do i check it in nqp code? is there something like nqp::isdefined? 14:01
jnthn nqp::isnull 14:03
or nqp::isnull_s for strings
14:04 snoopy left

colomon did not like Die Hard 2. :\ 14:14
timotimo which one was that? 14:16
mst timotimo: the one colomon doesn't like.
colomon timotimo: the one set at an airport 14:17
timotimo oh, i remember sitting in the theater and noticing a colomon in the back getting up and leaving now that you mention it 14:18
benabik Die Hard was a good movie.
colomon it felt like they were lazily trying to just clone what worked with the first movie without having a clue about what actually worked, if that makes any sense.
timotimo the first one was the one in the skyscraper, yes?
benabik Shame they never made sequels.
timotimo is still bummed out about the first three star wars movies never being made 14:19
colomon timotimo: yes, first one was skyscraper
timotimo ConfigureJVM.pl needs a --gen-jvm for all the people who don't have jvms installed on their machines! :P 14:20
benabik timotimo: Should we add --gen-gcc to Rakudo? 14:21
timotimo sounds like a good idea 14:22
i hear there's a new upcoming C compiler called "clang" that's gaining popularity fast
maybe we should add an option for that somehow
colomon Another good project: add --make-movie-better to ffmpeg... 14:24
timotimo java.lang.RuntimeException: java.lang.ArrayIndexOutOfBoundsException: 0 - oooh, how did i do that? 14:25
colomon I've gotten that several times in things that didn't involve arrays this week. :\
timotimo how do i pinpoint the problem? 14:26
it happens after the jast stage, fwiw
i guess i should first make sure that my changes are at fault 14:27
colomon oo, that's happening when you're building? ugh
*building rakudo
jnthn Wait, did you use an RT_VOID return type for an op? And it's not in sink context?
Or not not last thing in a block at least... 14:28
That's asking for trouble. Pretty much all the ops leave *soemthing* on the stack just in case.
timotimo oh, interesting
colomon hmmm, we're getting NullPointerException here: (my $line = self.get).defined 14:29
timotimo it's not the last thing in a block
colomon I think the time it's not defined.
timotimo should i return a long instead?
jnthn timotimo: Well, typically one of the arguments is a good thing to return...a null SMO can also be OK 14:30
long is fine too
timotimo i'll do that then. for now i put the closedir in sink context.
just to see if it compiles and passes any tests at all

TimToady well, they like stability more than coolth :) 18:02
mstefanko yes def.
but i can see also a bit why when i go through the online pages and docs. websites promoting perl tend to look very pre-2000ish 18:03
perl.org screams o'reilly at you
colomon lots of neat things still being done with Perl, www.thegamecrafter.com/ is one of my favorite examples. :)
mstefanko is the website built on perl or their products? 18:04

Ulti mstefanko: also bioinformatics is mostly perl 18:21
timotimo i wonder if catpath should be able to handle catpath(".", "./foo") properly
or if i should just cut off leading ./ from my elements in the dir traversal
18:23 dmol1 joined, dmol left
timotimo ah, it's even worse, dir("t") will give "t/t/..."), so i suppose i don't have to catpath at all. 18:23
TimToady lizmat: re irclog.perlgeek.de/perl6/2013-06-29#i_7267784 The compiler does need to know the complete identity of a module if it is to allow multiple versions to coexist at runtime
Ulti mstefanko: also I just created a startup and we're using perl on heroku for our web stuff... because its cool
mstefanko: that and I'm working with other people from bioinformatics who essentially only know perl... 18:24

timotimo any clues to why the jast phase takes about half as long as the parse phase? is that an okay time to take? (compared to parrot where it doesn't take quite as much, but there's a pir phase directly after that as well) 18:26

lizmat TimToady: wrt irclog.perlgeek.de/perl6/2013-06-29#i_7268923 : I'm not sure what you call the compiler here 21:39
The classes providing the CompUnitRepo interface, store the meta-information of compunits 21:40
pmurias nwc10: I'll try with the latest jdk from oracle 21:41
lizmat whenever a compunit needs to loaded, it will give this from/longname/auth/ver to each of the CompUnitRepo objects in @*INC
They then use whatever they need to return which compunist match in their repo 21:42
nwc10 I seem to be building NQP fine (and tests passing) with: 21:43
java version "1.7.0_25"
OpenJDK Runtime Environment (rhel-2.3.10.3.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
lizmat the repo also returns the meta-info of the candidates, which the compiler can use to set up introspection if the candidate is selected for loading 21:44
so the compiler *will* know all of the meta-information of a compunit when needed 21:45
raiph lizmat: i'm guessing larry's confusion is the same as FROGGS (irclog.perlgeek.de/perl6/2013-06-29#i_7267798)

lizmat raiph: indeed :-(
so: to recap: 21:47
raiph lizmat++ # right combination of skills, branepower, diplomacy, patience, impatience
lizmat *blush*
1. whenever a -use- is done in code, the CompUnitRepo-like objects in @*INC each get a chance to say whether they know of any matching candidate compunits 21:48
2. the compiler makes a choice out of these candidates, if needed, or throws an exception if nothing found or can't make a decision 21:49
3. when a compunit is selected, its meta-information (already provided to the compiler when making a choice) is installed as introspection info after the compunit is loaded 21:50
4. Rakudo will provide 2 implementations of CompUnitRepo: CompUnitRepo::Local::File (basically, the current behaviour) and CompUnitRepo::Local::Installation, which has a simple database, basically consisting of dump of a hash representation of the meta-information of installed modules, easily allowing smart-match logic on them 21:53
labster .oO (CompUnitRepo::Remote::CPAN -- store your modules in the cloud) 21:54
FROGGS .oO( CompUnitRepo::Local::DevNull -- install your modules to ... ) 21:57
lizmat labster: I would see that as an on-demand installation feature
FROGGS: I would see that as a way to make files appear to be *not* installed 21:58
FROGGS :o)
sorear ::CPAN could be cool 21:59
lizmat FWIW, I think each CompUnitRepo should be able to say that no further searching is needed
21:59 Rotwang left
FROGGS hmmm, not sure if I could agree 21:59
22:00 ecocode left
lizmat if you don't allow that, you will get modules that start fiddling with @*INC to get the same behaviour 22:00
FROGGS yeah, maybe you are right 22:01
if a repo says "hey, I've got a dev module here that should get picked no matter what" than this is the right playce to say so 22:02

10 tests in t/spec/S05-modifier/ii.t
24 tests in t/spec/S05-modifier/perl5_0.t 22:05
raiph lizmat: your design wouldn't preclude making all of CPAN plus local stuff appear to be installed, right?
lizmat and a lot of io-spec and io-path tests
FROGGS this could explain labster++ 's bug: github.com/rakudo/rakudo/commit/41...d003649594
