bacek_ summon pmichaud 02:13
spell failed...
purl failed... looks funny
particle what's up? 02:14
purl The Canadian Dollar
particle no shizzle, purl
purl particle: huh?
bacek_ msg pmichaud 'Is it good idea to reimplement List.(map, grep, reduce, first,...) as free function which accepts Sub and Iterator.
it will making of lazy lists more easy. 02:15
particle: almost Lunch time. 02:16
tetragon Hrm... decided to try running "make spectest", and a segfault fell out
particle tetragon: which test?
tetragon And it actually has SIGSEGV in the crash report, instead of the usual SIGBUS
particle: I think it came from t/spec/S12-class/basic.t 02:17
particle that's unexpected 02:18
tetragon The trace I have when I tried to reproduce it is different to the one that popped out during make
I'll paste my reproduction attempt
It had a double free
nopaste "tetragon" at 69.196.141.26 pasted "Fun with attempting to reproduce a spectest crash" (163 lines) at nopaste.snit.ch/13184 02:20
particle tetragon: you're running svn head, i assume? 02:21
tetragon Yes, current as of a couple hours ago
r28124 02:22
pmichaud bacek_: how exactly do you mean?
bacek_ sub 'sort' :method .return '!sort' 02:23
particle tetragon: definitely want a parrotbug filed on that
02:23 Patterner joined
tetragon is busy hooking gdb up to the crash 02:23
bacek_ sub 'sort' method .param pmc e .return '!sort'(e, self.'iterator'())
tetragon And it's now sitting in malloc_error_break
bacek_ s/sort/grep/
pmichaud why would we need a separate function for that?
bacek_ say (1..5).grep { $_ % 2) 02:24
particle tetragon: if you run ../../parrot perl6.pbc t/spec/... do you get that segfault?
...or is perl6 there a link?
naw, can't be link or alias
pmichaud i.e., why can't 'sort' return the generator directly?
that's more what I would expect.
er, grep.
(since sort isn't really lazy) 02:25
bacek_ > say (1..5).grep({ $_ % 2})
nopaste "tetragon" at 69.196.141.26 pasted "Yay, gdb at the breakpoint suggested by Apple libc" (49 lines) at nopaste.snit.ch/13185
bacek_ Method 'grep' not found for invocant of class 'Range'
tetragon particle: No crash
particle tetragon: after Parrot_exit! i'm the only one who's seen that before
particle hugs tetragon 02:26
finally, that bug has been reproduced!
...and not on win32+msvc
bacek_ pmichaud: i agreed that 'grep' should return generator.
tetragon This time on OS X 10.5/ppc
pmichaud bacek_: I'll have to think about it a bit.
bacek_: it's a reasonable approach, but I'm not quite sure that it's "right" 02:27
tetragon particle: So new ticket, or is there an existing one to append to?
particle isn't List the lazy one?
tetragon: new ticket please
tetragon now wonders which test it was that actually crashed during spectest 02:28
bacek_ pmichaud: software isn't cut from stone :) We can change it later
actually '!grep' will return generator. So every other classes can get benefit from calling it 02:29

tetragon particle: You want anything from the gdb session I have open? 02:39
particle tetragon: sorry, i'm too distracted right now, preparing for soccer
pmichaud List is lazy, yes, but so is Range 02:40
particle yes, range is lazy too
Whiteknight List and Range need to get off their asses and find jobs
particle you're one to talk, Whiteknight
pmichaud :-P
Whiteknight ...:( 02:41
particle :)
pmichaud: Range will for sure have a generator
Whiteknight got hit where it hurts. He'll shut up now
particle Range needs a generator that works from either end 02:44

cotto_home If anyone ever talks about PHP's design, they're wrong. 04:15
There isn't one.
Patterner "Repeating 5 year old mistakes" 04:19
cotto_home there wasn't an excuse for this mess ever, much less 5 years ago 04:20
of course, it'll totally be worth it once I can load a CPAN module from PHP 04:21
php? 04:22
Auzon purl, php?
purl php is really badly designed or swahili for "child molestor" or or Philippine pesos or the best or PHP: Hardly Programming or brought to you by the teletubbies or proof there is no god or xrl.us/t6wx or more modular than perl or the little transgender brother of perl or a WOMBAT or tnx.nl/php or easy or or was better when it was a templating system or blamed on Rasmus Lerdorf
Patterner A bit biased one might think. 04:24
cotto_home purl, php is also taking the worse-is-better approach to dazzling new depths
purl i'm sorry, but that's too long, cotto_home
cotto_home stupid bot 04:25
purl Up yours, too, bruddah!
Auzon dumb bot.
purl Go away or I'll replace you with a small and useless factoid!

japhb cognominal_, vany: New OpenGL portability patch for you two up on RT #55228 05:01
y'all are seriously making me work for it, aren't ya? 05:02
tetragon japhb: Just so you know, normal OS X boxes don't have /usr/include/GL 05:08
japhb tetragon: yes, I know. er ... and? 05:09
tetragon But they can have a number of different sets in /Developer/SDKs (which are normally only used if you're targetting a specific release)
japhb yep, noticed that from cognominal's hell
tetragon japhb: I looked at the ticket and you mentioned that you weren't sent /usr/include/GL
japhb tetragon: Ah, gotcha, now I see where you're going
tetragon My Macintel has the headers for 10.3.9
(And the 10.4 that is actually in use) 05:10
japhb Apparently, cognominal's box *did* have a /usr/include/GL, which included headers for non-core GL stuff, like GLEW. And GLEW was what was killing his configure.
tetragon You can't count on any mac having headers in /opt/local. The ones that do obtained them via (Darwin|Mac)ports 05:11
What I saw in the ticket was /opt/local/include, so getting it through darwinports
japhb I'm not even searching /opt/local/ ... should I? Is that "polite" on Mac OS X? Right now, I'm only doing /usr/include/GL/, /usr/local/include/GL/, and the Mac OS X Frameworks directories 05:12
Oh, and the Win32 $ENV{INCLUDE} path
tetragon I normally don't deal with anything there as I work from source (found fink and darwinports too annoying) 05:13
japhb wonders what crazy moon directories Solaris will want to use ....
tetragon: nodnod
DietCoke (searching) ... why not just search those paths that have already been identified as potential search paths? 05:22
you shouldn't be duplicating that logic in your little slice of config. 05:23
japhb DietCoke: explain, please. kid51 told me back in the early days that Configure currently has no way to track locations of where system headers can be found. 05:24
[OT] Oh ZOT! No wonder this $day_job sanity checking code is always returning false ... I forgot to add an "is sane" case. Sheesh. Been debugging that for half an hour ... 05:25
05:30 cotto-work joined
DietCoke japhb: perhaps it should? 05:43
though if it's currently being stored anywhere, no need to refactor it to make your stuff work. 05:44
not being.
(but I know, for example, darwin is already probing for fink/darwinports) 05:45
japhb DietCoke: yes, I believe there are some probes for non-standard locations (as with, as you say, fink/darwinports) ... but no probing or storage of "standard" locations. 05:51
In general, I think the config system needs some refactoring, but it's a task I'm putting off for the moment .... 05:52
For one thing, I need some more experience with the various pain points before I'm qualified to do a refactoring that doesn't just trade one set of problems for another. 05:53
(Though I admit that the 'make clean' versus 'make realclean' issue is really starting to bug me.) 05:54
DietCoke well, if you're dabbling in config, that's unfortunately to be expected at the moment.
though it seems a reconfig should be fine in most cases.
japhb Oh, I always do 'make realclean' anyway (old habit) ... it's the problem reports from other people who just did a 'make clean' after I committed an OpenGL change and something didn't work. It's a bug in the config/build process design, not a bug in my code per se, but I get the bug anyway. 05:57
DietCoke ah, that. I addressed some of that in my response to you a few days ago.
japhb I mean, if even someone who has been at it as long as you sometimes trips over that, there's a problem.
DietCoke oh, definitely.
japhb DietCoke: yep, that's what I was referring to. 05:58
I'm leaving your ticket open at the moment while I ruminate on what I want to do about it. (How much do I want to bite off) 05:59
DietCoke most of my rant belongs in a new ticket(s). =-)
japhb true
If you feel like opening a new ticket with the rant, and resolving the old one, that's fine by me. Just let me know what the new RT # is (or add me as a watcher or whatever the RT equivalent is) 06:00
Because even if someone else does the work, it's still going to have a major effect on the OpenGL stuff. 06:01

I just need little bit of luck to find free time.
Zaba bacek_, eh.. what should my $a = (1..5); assign to $a? 07:23
I can't think perl 6 yet 07:24
:/
moritz Zaba: a capture that holds the range, or a Range object or something along these lines
Zaba hmm..
what about my @b = $a, then?
moritz it evaluates $a in list context 07:25
pugs assigns a List or Range to the first item of @b 07:26
Zaba and Range knows how to get converted to an array, right?
moritz I hope so ;-)
well, yes 07:27

jonathan_ A Range is an iterator, and it's .from (or .to if you iterate from the other end) change as you iterate it. 08:02

link: www.perlfoundation.org/parrot/index...for_parrot
shorten dalek's url is at xrl.us/bkxq5
jonathan_ Thus in the above example, it's getting iterated to produce values when it's evaluated in list context the first time. But it should perhaps clone itself so you can do that many times...I'm not completely sure.

bacek_ jonathan: 55400
jonathan bacek_: I think it should clone itself in list instead
In get_iter it should return itself, because it is an iterator 08:12
bacek_ but shift_pmc destructive.
or its supposed to be destructive?
dalek allison@perl.org | Bylaws: 08:13
link: www.perlfoundation.org/parrot/index.cgi?bylaws
jonathan Yes, it is.
See S03, Range Semantics.
Explicitly says these operations are destructive. 08:14
I'm not completely sure the semantics you saw in your program above are out of line with S03, if a bit surprising.
But if they are wrong, the place to clone the iterator is inside Range's 'list' method. 08:15
bacek_ jonathan: already remade my patch
actually implement clone :vtable
jonathan Aha, good. 08:17
nopaste "bacek" at 211.29.157.151 pasted "Fixed Range with clone using" (40 lines) at nopaste.snit.ch/13193

moritz how do I build and run the demo? 10:11
cognominal_ parrot ./examples/opengl/triangle.pir 10:13
moritz cool 10:16
bacek wanders why 'return' not implemented yet... 10:45
masak bacek: yeah, I see what you mean. apparently it's not trivial. 10:46
bacek masak, why?
masak I don't really know
moritz bacek: because it's not yet in PAST
it's implemented through control exceptions
and that was only recently refactored in parrot 10:47
masak how recently?
so now it's possible?
moritz now it's possible to do it in PAST
bacek wow
masak moritz: is there a PDD explaining all this?
moritz masak: presumably, yes... looking 10:48
masak (or a document of some sort)
moritz docs/pdds/pdd23_exceptions.pod 10:49
masak gracias
moritz svn.perl.org/parrot/trunk/docs/pdd...ptions.pod
shorten moritz's url is at xrl.us/bmmku
moritz purl, moritz's url? 10:50
purl bugger all, i dunno, moritz
moritz ok, not that stupid ;)
masak that's a humorous interchange :)
moritz I try to hack and IRC -Ofun ;) 10:51
masak so -- see if I get this correctly -- a return is a kind of exception?
moritz yes
a "control exception"
masak I think we just overused the term 'exception' in its original sense
to me returns are very unexceptional 10:52
but nvm
moritz "exception" = "dynamically scoped stack unwinding"
masak yeah, sure 10:53
moritz or s/stack/continuation/
masak my complaint was more along the lines that 'exception' is taking on a semantic life of its own within CS
but it probably did long ago anyway
moritz so did words like "regular" 10:54
masak and "function" :)
getting back to return=exception, what is it that catches a return exception? 10:59
an implicit try block around the method call?
moritz I think an implict try block around the function body 11:00
so the try is on the callee side, not on the caller side
11:01 Whiteknight joined
masak ah, so the thrown exception makes the control flow end up at the bottom of the callee? 11:01
makes sense
and it's this mechanism that needs to be added?
and it's essentially a Simple Matter Of Programming? 11:02
moritz think so, yes 11:04
if it's done in PAST, it should be trivial to add in any HLL that uses PAST
but I don't know how "Simple" that SMOP is ;)
masak 'HLL'? 11:05
moritz high level language
masak ah
moritz parrot-speak for "language implemented on top of parrot"
in other words "send PATCH" ;-)
masak so all HLLs compile down to PAST?
moritz most 11:06
masak is this what rakudo's actions.pm generates? 11:07
moritz aye
masak nice -- another stepping-stone towards enlightenment
thank you
moritz yw
masak so once actions.pm has done its work, where does the PAST go? 11:08
moritz one of the compiler/*/ thingies I guess
compilers/pct/ that is 11:09
jonathan compilers/pct/src/past/compiler.pir, I believe
Which turns it into POST
masak PAST->POST 11:10
purl PAST->POST is (designed to be) hll independent
masak thx, purl
purl please don't say "thx", if you're genuinely grateful it's worth the effort to type three extra characters and say "thanks". this is IRC, after all, not SMS or twitter
masak :) 11:11
ic
moritz purl, PAST->POST is also compilers/pct/src/past/compiler.pir
purl okay, moritz.
masak would it be feasible to intercept the PAST before it goes off to compilers/pct/src/past/compiler.pir, and manually add in nodes that simulate a return? 11:12
just to get a feel for how it would all work
moritz ../../parrot perl6.pbc --target=PAST $source_file
don't know if the output format is easily usable for re-evaluation, though 11:13
jonathan Well, you can also insert a stage into the pipeline
There's just a string inside I think perl6.pir
We already added the check stage to make -c work.
In the ML compiler I'm planning to work on, I expect I'll add a typecheck stage. 11:14
masak I'll look into how make -c works, then
s/make -c/-c/
jonathan And I'll make cheese sarnies for lunch. 11:15
masak :)

cognominal_ sarnies? 11:25

right when you think you know the English language fairly well, you meet an Englishman... 11:27
moritz ... or you go to scottland and think "wtf? this is *english*?" 11:29
masak loves Scottish 11:30
moritz of course they don't speak English there, but a somewhat rude approximation. Tooke me some time to figure out
masak I listen in to BBC Scotland sometimes
cognominal_ masak, I spent 3 years in the silicon valley, so I am more used to american english than regular english. I have trouble with many English accents. But jonathan, I understand pretty well when he speaks. 11:37
and he is giving great talks too at conferences 11:38
masak definitely
I visited .nz a few years ago, and had to learn new words for ordinary concepts, like "boot" and "beanie" 11:39
cognominal_ and he appreciates french cooking so he has become a regular at french perl workshops. 11:40

12:06 barney joined
moritz yes 12:06
bacek moritz, but it works :) 12:08
moritz why does it need an extra namespace?
bacek for 'isa'. I don't want to catch wrong exception
moritz ok, makes sense 12:09
so the namespace isn't visible in p6 land?
masak patch -p1 < the-return-of-bacek
bacek moritz, not sure. Probably visible. 12:11
moritz aye, just tested it 12:12
it builds ;)
bacek moritz, WOW :)
moritz tests so far were all fine 12:13
masak hm, I got "Could not find non-existent sub return"
moritz > sub foo { 2; return 3; 5; }; say foo()
3
masak maybe I ran make in the wrong way...
moritz masak: did you add the Return.pir file? 12:14
masak let me check
moritz if you just did a patch -p1 < patch you didn't
t/spec/S12-role/composition................Null PMC access in type()
masak ah
moritz bacek: your patch breaks a few tests in 'make fulltest', but it's a nice start 12:15
> sub foo { 2;{ return 3;}; 5; }; say foo()
[oops; continuation 0xb64243cc of type 22 is trying to jump from runloop 985 to runloop 52]
masak moritz: don't do that then! :)
pmichaud_ the except handler belongs inside the called sub
not in the caller 12:16
also, not all statement_blocks are subs.

jonathan pmichaud: Should the iterator method really do $P0 = clone self? 13:10
Since a Range is an iterator anyway. 13:11
pmichaud I think that 'shift' should modify the range, but shifting on the thing returned by 'get_iter' should not. 13:14
in particular:
my $a = 1..5; for =$a { say $_; }; say $a; 13:15
I don't know that iterating over a range should deplete the range.
jonathan I'm not 100% sure on this either. 13:17
However, a range is an iterator itself, and S03 says that when as it is iterated, the to and from change.
s/when// 13:18
Well, to or from if you iterate at just one end. :-)
13:19 Whiteknight joined
pmichaud well, I'm sure that shifting or popping a range modifies it. Despite what S03 says about prefix:<=>, I'm not so sure. 13:23

DietCoke does parrot currently support multiple iterators via get_iter? 13:27
pmichaud you mean for the base types? I don't know.
seems like it should.
DietCoke tcl's syntax gives you an ID for the iterator... [ set a array startsearch arrayName] [array nextelement arrayName $a] 13:28
gonna have to store a list of iterator ids on my hash-like object. 13:29
(er, tcl spells hash, 'array')
jonathan pmichaud: Hmm. Pugs seems to agree with you. :-) 13:31
pmichaud yes. but we also have:
jonathan But I think maybe best is posting to p6l for clarification.
pmichaud 13:28 <pmichaud> pugs: my $a = 1..5; my $b = =$a; say $b; $b = =$a; say $b; say $a;
13:28 <exp_evalbot> OUTPUT[1ā¤2ā¤3 4 5ā¤]
jonathan Curious. 13:32
purl hands jonathan a dead cat
pmichaud I'd probably post the question to p6c.
jonathan ok
will tonight if you don't beat me to it.
pmichaud I tend to use p6l for questions about Perl 6 design, and p6c for questions about clarification of the spec 13:33
jonathan Right now I'm bogged down in some...wait for it...CSS refactoring. :-(
pmichaud you'll probably beat me to it, at any rate.
DietCoke pmichaud: since you own PGE, can you comment on rt.perl.org/rt3/Ticket/Display.html?id=55210 ? 13:39
pmichaud I'll take the ticket for now. 13:40
I don't have a good comment at the moment. 13:41
it's a good idea, but instead of adding the opcode and then trying to figure out how PGE can use it, I'd rather figure out what PGE needs and then write an opcode to support it.
but I've been thinking along these lines with respect to longest token matching, yes. 13:42

[oops; continuation 0xb7516fec of type 22 is trying to jump from runloop 3339 to runloop 3226]
Null PMC access in clone()
oh. $!from and $!to are uninitialized in the protoobject. 14:09
$P0 = self.'from'()
from = clone $P0
jonathan pmichaud: I worked around that bug in Junction. 14:10
pmichaud .sub 'from' :method $P0 = getattribute self, '$!from' .return ($P0)
.end
we should check for null there.
DietCoke whenever I see that now, it's often an exception getting thrown from PIR through C into PIR again.
you might actually get the exception properly in the cx branch. (if it's building atm.) 14:11
jonathan pmichaud: It's only the proto that has the issue. The call to new, for instances, fills all attribute slots with undefs.
DietCoke We are down to 48 tickets that don't have some kind of [TAG] in them.
jonathan Thus for any normal instance you know it's never null and can skip the check.
I *think* proto-objects probably should blow up on state access anyway... 14:12
pmichaud I wonder why .WHAT is generating a clone anyway
(protoobject blowups)++ 14:13
however, I'm not sure that calling new should fill all attributes with undefs. 14:14
(for the same reason that saying my $a; should not automatically fill $a with undef) 14:15
(namely, existence.)
jhorwitz pmichaud: any further thoughts on the metaclass issue i was having yesterday? 14:18
namely this: Method 'item' not found for invocant of class 'Apache;RequestRec'
pmichaud jhorwitz: yes, I think I need to convert item() into a function.
that then re-dispatches to the method if it exists. 14:19
jhorwitz when is that invoked?
pmichaud assignment.
purl assignment is different in scalar contexts than in array context
jhorwitz ah, so when i pass $r to a mod_perl6 handler, it gets assigned
pmichaud yes.
jhorwitz is that significant work on your part? 14:20
pmichaud but I don't think we can rely on every object (e.g., non-Perl6 objects) having a .item method.
no, not too significant.
I can take care of it in about an hour or so.
actually 90 mins. (right now $otherjob calls.) 14:21
jhorwitz needs to pay the bills as well. :)

moritz japhb: you get a better overview of the active branches when you delete the inactive ones

moritz masak: thanks ;)
masak np ;)
pmichaud in particular, because PIR doesn't recognize "[]" as an empty key yet
Whiteknight pmichaud, that's okay, that's what I figured
pmichaud (this is why I was also commenting that we shouldn't rush to deprecate ".namespace" yet.)
Whiteknight that's why I ask first
masak has been listening too much to 'tirdy point buck'
pmichaud I think the answer is for PCT to see if CodeString.key returns an empty string, and replace it with "[]" when generating the namespace directive. 16:33
Whiteknight okay, well both ".namespace" and ".namespace []" work currently, so there is no hurry either way. I'll put the ticket on the back burner
pmichaud or, have CodeString.key generate "[]" for an empty namespace, and check for that when generating a get_* opcode. 16:34
but I think this latter option is much more difficult.
(because there are so many opcodes involved.)
Whiteknight okay, i'll make a note of the options in the ticket, and we can wait till we're ready to move on it 16:38

pmichaud I suppose, but PIR really expects to have the equivalent of the parrot VM underneath it.
So, you could compile it to C, but you'd still need "objects" representing arrays and hashes 22:20
