#parrot Parrot 0.6.1 "Bird of Paradise" Released | parrotcode.org
Set by moderator on 29 April 2008.
pmichaud Null PMC access in invoke almost always refers to trying to call a non-existing function 00:01
obra is there a faq for this sort of stuff?
pmichaud we could create one. But I don't know where to put it. 00:02
particle wiki
00:02 patspam joined
pmichaud actually, one probably already exists. But I don't know where it is. 00:02
fwiw, it's not specific to rakudo -- it really exists for Parrot and for PCT
in PIR, "foo"(1) gives "Null PMC access in invoke()" if foo doesn't exist. 00:03
00:05 TonyC joined
pmichaud reporting sane line numbers is RT#43629 and RT#53082 00:05
obra and there's no way to find out what the missing sub being called was/ 00:06
?
pmichaud I'm looking up the RT ticket for that one :-) 00:07
obra Ticket # won't help me much ;) it's all fine
wknight8111 sane line numbers? I vote for that one!
pmichaud RT#49972 explains why it doesn't work.
I'm pretty sure I'll need to update PCT to report missing subs
since I don't think Parrot will do it anytime soon 00:08
obra is there a way to tell rakudo to keep running after a parrot failure? 00:10
00:10 zarchne joined
pmichaud ... try ? 00:11
fudge allows
$?rakudo try [num] 'reason'
obra was pondering whether p6 gives us enough rope to make ok() insert an inner frame that wraps a try in there.
pmichaud which puts 'try' blocks around the tests that follow
obra ok 00:12
pmichaud it's very useful to read the fudge code at the beginning
obra Sorry. I'm very much a newbie at this
pmichaud svn.pugscode.org/pugs/t/spec/fudge
in truth, we all are. Even I'm having to look up the items as you ask for them :-) 00:13
obra nods
#? rakudo [num] try 'reason'
particle and i keep giving wrong answers
pmichaud no space between #? and rakudo
yes, I typoed above 00:14
TimToady obra: I've tried all sorts of such tricks, and the preprocessing is by far the most straightforward
obra TimToady: understood 00:15
it's also the most likely to work early on
TimToady but the main advantage of the fudge approach is that it is completely obvious when you aren't using it
obra Even if we'll be able to do sick things once we have a fully operational death star.
er. Perl 6 implementation
TimToady whereas all sorts of niggly hooks, you don't know if they're turned on or off
pmichaud I really like the fudge impl, fwiw. TimToady++ and particle++ 00:16
TimToady with fudge, just *don't do it*, and if it works, you're golden
the disadvantage of fudge is that you have to be a little disciplined in how you write individual tests
pmichaud discipline in a specification test suite is probably a good thing, though. 00:17
particle discipline for the masses! freedom for all!
obra Is my discipline obviously lacking in this: paste.husk.org/11313 ?
pmichaud obra: you may be the first person to try 'try' in fudge :-) 00:18
particle obra: s/\\#\\$\\?/#?/ 00:19
TimToady you don't have to put the number if it's 1
pmichaud oh yes, I had the number in the wrong position in my examples.
Apparently tonight I'm only good for general pointers, not for exact syntax :-| 00:20
TimToady that's why the number is where it is, so it's easy to tell if it's missing
obra particle: you win
TimToady pointers...are those kinda like references, whatever those are?
obra except, no
adding a second test of ok(1); reports two failures
or maybe I have another typo 00:21
pmichaud obra: you may be the first person to try 'try' in fudge :-) :-)
or in rakudo, for that matter.
particle it works in rakudo
we have sanity tests for try, iirc
obra nods
pmichaud no, I meant fudge's try in rakudo
particle ah, mebbe 00:22
pmichaud I know that try { ... } "works" in rakudo.
TimToady it's easy enough to look at the .rakudo file and see what fudge did with it
the thing about try is that it can't really tell how many tests ran inside a block before it failed 00:23
(if you use the block syntax)
pmichaud gives the whole thing a try.
er
TimToady presumably that sort of thing gets caught by the "planned" number
obra #?rakudo 1 try 'i hate this'
(try { is( 2147483647 + 2147483647, 4294967294); }) // fail('i hate this')
I would expect a trailing ; 00:24
Is that my p5 showing through?
TimToady could be a buglet
obra also, it looks like there's no sub fail defined. 00:26
pmichaud aha
that's likely
obra should that be 'flunk'?
or is flunk something else?
pmichaud what's the p6 def for fail()?
TimToady fixed the ; 00:27
pmichaud (i.e., where is it defined?)
particle fail is for grammars
pmichaud just for grammars?
particle well, probably not
but it's likely that's why flunk exists
pmichaud fail() is mentioned in S04
TimToady okay, fixed that too 00:28
obra TimToady++ # fast enough turnaround that I didn't manage to get into fudge
TimToady should be flunk in any case, since fail would return an exception instead of continuing
pmichaud is flunk() a Test.pm function? 00:29
particle not yet
pmichaud I mean in pugs
we need to add flunk() to Test.pm 00:30
TimToady yes, pugs has flunk, I believe
pmichaud Test/lib/Test.pm
261:sub flunk (Str $desc?, :$todo, :$depends) returns Bool is export {
(in pugs)
obra needs to wander home. thanks for the intro help
pmichaud thanks, obra!
TimToady obra++
obra with luck I'll manage to get this far enough along to move arith.t into spec over the next couple days and write about it 00:31

nopaste "chromatic" at 69.71.189.252 pasted "[proposed PATCH] Throw Exception when invoke()ing NULL PMCs" (26 lines) at nopaste.snit.ch/12871 00:37
obra paste.husk.org/11314 00:38
that's a first, bad stab at "make fudge's flunk work"
pmichaud looks pretty good to me 00:39
although could even simply do proclaim(0, $reason) 00:40
particle it's two separate patches, but it looks pretty good
pmichaud having "flunk" there does make it clearer
two separate patches?
obra the two changes are not tightly coupled
particle sure, one is to fix proclaim to include the description
it's worth applying 00:41
obra wonders if he actually has a commit bit to Parrot
pmichaud I'm confused... doesn't proclaim already include a description?
obra: if no, I'll apply in just a second
00:41 patspam left
pmichaud (also dealing with kids and students in other windows) 00:41
particle if it's todo, it includes only the todo reason from fudge 00:42
obra if $todo is defined, that was clobbering the reason
particle not the individual test reason
obra er. which seemed kind of subpar
pmichaud applying. 00:43

diff: www.parrotvm.org/svn/parrot/revision?rev=27279
pmichaud (chromatic's patch) .... doesn't Parrot already throw an exception when invoking a NULL PMC? I don't see the purpose of the patch. 00:49
particle it makes the invokecc op throw an exception before trying to invoke a PMCNULL 00:51
rather than having the Null PMC throw an exception when the invoke vtable function is called
00:52 pasty joined
particle at least it has a type, GLOBAL_NOT_FOUND, that you can catch 00:52
pmichaud that seems... wrong
How do we know that the Null PMC is due to a global not found?
it could've come from a variety of sources
particle i agree. 00:53
the exception should be thrown in find_global
pmichaud I don't want an exception there, either
particle hey, you're looking for something to invoke, and i can't find the thing you're looking for
pmichaud did you mean find_name? 00:54
or get_global?
in either case, how do you know that the thing you're looking for was something to invoke ?
particle i'm too far removed to know the exact name
pmichaud we use get_global and find_name to get things other than subs
and "null" is the standard way we have to determine that the thing doesn't exist.
if parrot is going to try to solve this problem, it needs to do so in the code it generates for a symbolic sub call invoke 00:55
i.e., instead of generating
$P0 = find_name 'foo'
$P0(...args...) 00:56
it needs to generate
$P0 = find_name 'foo'
unless null $P0 goto label
throw "cannot invoke 'foo'"
label:
$P0(...args...)

pmichaud ...but I'm thinking I can do the equivalent in PCT without having to modify Parrot 00:59
Tene debates between cardinal, lolcode, and naptime.
Coke pmichaud: tcl is currently doing the latter.
particle tcl is doing naptime? 01:00
Coke if there's a shortcut, that'd be nice, but the various languages might not deal with it the same. 01:01
no, but I am.
pmichaud I think I'll add it as a flag or option to PCT 01:02
Coke tempting to to put that in an opcode. invoke_by_name 01:03
pmichaud no, because we have to do calling conventions
Coke hurm. find_or_die, then. =-) 01:04
(but that's probably not worth it.) 01:05
pmichaud it would be nice to have find_name with an optional flag to decide whether to throw the exception or not 01:10
but that's just another form of find_or_die I guess.
particle we've previously discussed compiler pragmata
Coke yah. I'm fine with it either way. I don't like pragmata at the assembly level. 01:11
particle .failure_mode 'throw'
.failure_mode 'null'
whatever.
Coke perhaps some PIR sugar to automatically throw an exception, though. that I could get behind.
particle $P0($P1, $I2) :throw 01:12
Coke I was thinking it would go on the find_name.
particle easy enough if you make that a method on the namespace 01:13
just need to update NameSpace PMC to use PCCMETHODs more fully 01:14

Tene Wow, I forgot how slow cardinal was. 01:28
nopaste "tene" at 67.111.53.82 pasted "cardinal is really slow" (30 lines) at nopaste.snit.ch/12872 01:29
Tene 10s just to call a couple of functions. 01:30
most of it is just parsing.
--target=parse is 9s 01:34
01:37 grim_fandango joined
pmichaud parsing is still the slow part of things, yes. 01:48
that's why I'm looking at revising pge
(looking at cardinal's grammar to see if there's anything obvious) 01:49
although it shouldn't take 9s to parse that relatively small program. 01:50
ohhhhh 01:51
probably ought to memoize the <ws> rule
it's almost worth creating a subrule just for that
I think pct should provide a memoize function for <?ws> 01:52
Tene clever 01:53
obra how would one define an lvalue .sub for a rakudo core function? 01:57
Tene obra: what are you looking to make?
obra undefined 01:58
purl i guess undefined is false, but so are some defined values
obra er
undefine
pmichaud lvalue sub... I suspect one just puts a sub on the lhs of an assignment 02:09
but I'm not sure it will store the value anywhere 02:10
that's not exactly something we've done yet :-)
what is undefined?
purl well, undefined is false, but so are some defined values
pmichaud er, undefine?
oh, you're just looking for something that is rw? 02:11
.sub 'undefine' 02:12
.param pmc x
$P0 = new 'Undef' # this isn't real p6, but it works
copy x, $P0
.end
obra something that modifies its argument 02:13
I'm digging for where in the syns I saw the spec for undefine.
or whether I'm hallucinating
I see it in Perl6/Spec/Functions.pod and throughout the tests 02:15
but only a single reference in dev.perl.org/perl6/doc/design/syn/S04.html 02:16
(copy was the bit I hadn't figured out) 02:18
Tene I'm trying to recall what the problem was with persuading cardinal to allow function calls as arguments. 02:20
I had it all figured out, but didn't get around to fixing it before I forgot it, quite a while back.
obra so, assuming that undefine is supposed to be a core function, I have the patch, with test
Tene It's recursive somehow... 02:21
02:26 rdice joined
Tene I don't know if the parse tree for foo(1) in cardinal is funny or scary. 02:26
obra hey rdice 02:28
rdice ahoy!
pmichaud undefine is probably not in the synopses yet 02:29
that's true for a lot of the builtin functions. Spec/Functions.pod is essentially the draft of S29, iirc
obra nods
do you want an undefine? ;)
pmichaud if the spec doesn't cover something, then Spec/Functions.pod is the next-best-thing for now 02:30
sure!
patches welcome.
purl That's swahili for "Put up or shut up."
obra Pasted to: paste.husk.org/11315
next question:
purl it has been said that next question: is the source sensible?
pmichaud in this case it's english for "If you send me a patch I'll be very happy and give you a karma point." :-)
obra I'd guessed ;) 02:31
Tene karma++
obra my $a;
$a++
BOOM
pmichaud rakudo needs help with its Undef work
technically P6 no longer has an Undef
so we have to define the Failure type
and then define the increment operation on it
and I think we just haven't quite gotten around to that yet 02:32
Tene I wonder how much this grammar could be condensed without losing anything important...
pmichaud Tene: I think that memoizing <.ws> will save a ton of parsing time
after that, ltm will be the best bet. I didn't see any obvious grammar condensations in my quick perusal of it
Tene pmichaud: I'm looking for sanity in trying to fix it, not for speed.
the current grammar allows foo(1), but not foo(foo(1)) 02:33
pmichaud *that's* odd
I thought you were talking about something like foo(bar) where 'bar' is another function
Tene It appears that all you need to do is add <command> to basic_primary, but that loops forever. 02:34
pmichaud (working on applying obra patch, but also need to svn up parrot so will take a few mins)
obra pmichaud: no worries. 02:35
Tene the things I'm looking at cleaning up are some of the multiple-variants-on-the-same-name which all call each other.
obra is there a right place for failing tests of incrementing from undef?
pmichaud good question. I'd guess somewhere in S03 (operators)
Tene Oh! I should make a graph! Where's the grammar-to-graphviz script, I wonder...
pmichaud probably whatever is testing the increment operator itself
I think there's already an autoincrement.t in t/spec/03-* 02:36
02:36 davidfetter joined
pmichaud tene: adding command to basic_primary is probably correct, but you have to make sure it gets tested before other things that might be a subset 02:37

diff: www.parrotvm.org/svn/parrot/revision?rev=27280
pmichaud also, anything that can be converted from 'rule' to 'token' would probably speed things up a bit also
so as to avoid all of the extra calls to <.ws>
obra I can't actually find anywhere in S03 that says we should coerce an undefined value to 0 for autoinc
pmichaud it likely falls under the "anything not mentioned is still like p5" 02:43
otoh, S04 says that if we try to do something with a Failure value, then it throws an exception
so.... I dunno. At this point I'd probably ask p6c, p6l, TimToady, or #perl 02:44
er, #perl6
Tene pleasedieinafire.net/~tene/cardinal.png
pmichaud or pugs. :-) 02:45
obra bah. my pugs commit bit appears busted. 02:46
Pasted to: paste.husk.org/11316
anyone with a pugs bit easily able to add those to autoincrement tests cribbed from the syn? 02:47
pmichaud I've got one -- just a sec
note that there was recently some dicussion on postfix:<++> on p6l; I don't know that anything made it into the spec. 02:48
obra nods 02:49
all I've done is added the weird examples from the syn
pmichaud well, the weird examples were the things being discussed. :-) But I'm pretty sure the changes you made are still spec-compatible. Besides, we should write to what's written in the spec, not what's discussed on list. :-)
r20354 (pugs) 02:50
Tene rules like the <mrhs> rule in cardinal make me nervous. 02:51
pmichaud seems reasonable
they've just chosen to handle ',' as a syntactic element outside of an opp 02:52
obra pmichaud: thank you.
pmichaud (operator precedence parser)
obra -> sleep
pmichaud obra++ # many nice patches
obra maybe tomorrow, I'll try to get arith.t to pass
oh. last question
Tene Why have <mrhs> that just calls <args>, though?
obra rakudo appears to require () on function calls at this point.
pmichaud (I'll be travelling much of tomorrow... but others will be around to help)
obra I also have a ton of actual work I need to do ;) 02:53
pmichaud NQP requires (), but rakudo doesn't
er, rakudo shouldn't.
Tene Even the method is just: make $( $<args> );
obra hm. I wonder why it flips out when I don't have () for ok and for undefine
pmichaud ok '1'; # fine in rakudo
Tene > say "foo";
foo
purl bar
Tene yeah, works fine.
obra Syntax error at line 10, near "undefine $" 02:54
current instr.: 'parrot;PGE::Util;die' pc 120 (runtime/parrot/library/PGE/Util.pir:82)
pmichaud interesting.
obra hm.
pmichaud nopaste source?
obra maybe it's just undefine.
pmichaud even undefine should work.
ah 02:55
obra Pasted to: paste.husk.org/11317
pmichaud I suspect the grammar is stopping at 'undef'
obra heh

pmichaud for example, I've see things like (p6 equivalent) token then { 'then' }
you're correct that in this case it could be eliminated, since <mrhs> is only called in one location ( <assignment> ) 03:00
Tene The <mlhs> thing is a bit weird...
pmichaud it's "multiple left hand side", yes?
Tene Yeah.
Essentially: rule mlhs { <lhs> | '(' <mlhs> ')' } 03:01
pmichaud they might not have been easily able to write a self-recursive rule 03:02
(I'm just pulling at straws... ) 03:03
Tene Please note: this isn't significant questioning, just idle chatter while I try to swap this whole grammar in.
pmichaud right
same here
(while I do other stuff, such as close the 20+ windows I've managed to open over the past 90 minutes)
tetragon Hrm... When is the symbol '_environ' defined? 03:15
Tene pmichaud: s/rule/token/ in several places reduced the time to 4.1s for me. 03:17
pmichaud tene: yes, that's pretty significant. If I get a few free tuits tonight I might quickly add memoize to PCT::Grammar and try that
Tene Really, <primary> should be calling <command>, not the other way around... 03:20
03:20 petdance joined
Tene Wait, why does Cardinal's grammar have both infix:= and an assignment rule? 03:25
wtf?
oh, multiple assignment, I guess.
pmichaud hmmm?
that would be odd
wknight8111 cardinal is ruby-ish, right?
pmichaud I suspect infix:= is extra
multiple assignment is within the assignment rule
wknight8111 purl cardinal? 03:26
purl cardinal is mail.freesoftware.fsf.org/pipermail...dinal-dev/ or the Ruby-on-Parrot project. or xrl.us/uyz3
Tene I wonder if there would be problems if I just implemented infix:, instead
pmichaud is the current comma handling causing an issue?
I think you're probably better off keeping commas out of the opp, for most languages
Tene not really, but it looks like it would possibly simplify some things. 03:27
pmichaud (I could be wrong about that, but that'd be my first guess)
actually, I suspect that cardinal is currently using infix:= where it should be using <assignment> 03:28
(in terms of generated code)
Tene nodnod
me too
pmichaud afk for a while 03:32
tetragon Got parrot to compile/link on OS X without '-undefined dynamic_lookup' set 03:37
(Including OpenGL)
With -fvisibility=hidden removed from the flags (and not using -j2), there were two points that I encountered difficulty 03:46
2) The GLUT callbacks needed to be pointed at libparrot to before they could link 03:48
1) When linking libparrot, I needed to add '-Wl,-U -Wl,_environ' for it to work as pmc/env.c refers to the undefined symbol char **environ 03:50
(That linker flag allows the specified symbol to be undefined) 03:51
Tene Ack, the precedence is all off in cardinal 03:58
Or possibly not precedence...
n + 1 parses as n( 'infix:+'( 1 ) ); 03:59
04:01 japhb joined, Zaba_ joined
Tene Allowing a full <primary>:: or <primary>. before a call? That doesn't sound right. 04:01
That would allow a call on 'if's and function defs and such. 04:02
Infinoid tetragon: the "environ" symbol is provided by the C library, on linux. yours doesn't? 04:05
Tene 1 + 1 parses, but 1 - 1 doesn't?
Weird.
Infinoid a comment in the source says it is specced in POSIX.1, but if that were the case, we could probably just #include something, rather than declaring it directly
tetragon The symbol is declared in env.c, but the linker wants the symbol 04:06
Infinoid well, its declared as extern, so it is looking for the actual implementation of it somewhere else
(the code assumes its provided by the C library)
tetragon haha, libSystem.dylib doesn't define a symbol "environ" 04:07
Infinoid do you have an environ manpage?
tetragon It's there 04:08
Infinoid on linux, its apparently considered part of the execve() API, so its listed on that manpage, and apparently declared by unistd.h
tetragon Complete with the same declaration line that's in env.c
Infinoid k, so what do you have to link against to get it? :)
% nm /lib/libc.so.6 | grep environ 04:09
00000000000335c0 t __add_to_environ
00000000003449f0 B __environ

00000000003449f0 V environ
0000000000343240 b last_environ
tetragon That's not how it's done on OS X
"Shared libraries and bundles don't have direct access to environ" (from environ(7))
Infinoid well, that's not POSIX-compatible
so be it. we should rework env.pmc to handle OS X in a different way 04:10
tetragon The manpage tells how to access it
Tene oh, it's trying 'is equal' instead of 'is equiv'
tetragon I'll have to add in some changes to use _NSGetEnviron() in crt_externs.h to get environ's address 04:11
(And hope that someone out there has an OS X 10.5 Intel Mac available for testing. I've noticed differences from time to time between the i386 and ppc OS X ports) 04:12
Be back in a few minutes
Infinoid you could probably work around it by declaring a parrot global named Parrot_environ, that goes into the parrot executable, and is initialized to environ
Tene Hm.... infix:< doesn't work. 04:16
04:22 tetragon joined
tetragon Bah, the i386 (10.4) environ manpage makes no mention of any issues such as those on the (10.5) ppc. 04:25
04:26 Theory joined
Infinoid really. so does it work? 04:27
the _NSGetEnviron() hack looks pretty easy to implement, in any case...

You'd almost think that Apple has multiple paths to the exact same data
Infinoid what's something I can #ifdef for, for OSX fixes? 04:31

tetragon By default, HFS+ is case insensitive 04:32

tetragon (Although, the warnings that can occur as a result of a miscapitalised package name are rather tedious)
Infinoid I bet it causes weird %INC mismatches. 04:35
so... what can I #ifdef for, to detect OS X?
can I just "#ifdef darwin"? 04:36

nopaste "Infinoid" at 75.28.78.127 pasted "tetragon: how about something like this?" (63 lines) at nopaste.snit.ch/12874
Infinoid (that'll probably fail c_indent.t)
tetragon Failed 04:44
Couldn't find _environ 04:46
I'm trying with __APPLE_CC__ for now
Works with the check switched to #ifdef __APPLE_CC__ 04:47
Infinoid both checks, I'm guessing 04:48
thanks
are any other compilers available on OS X other than Apple's?
(intel-cc for example?)
tetragon Looks like xlc (IBM's C compiler) is available 04:49
But xlc does come with a gcc compatibility mode (at least on AIX) 04:50
Infinoid well, this probably won't work for that compiler then... dunno how much we care
tetragon I'm not sure if that extends to OS X and Apple's changes to gcc
Infinoid seems unlikely
then again, without supporting bundles and frameworks, I doubt it would be very useful at all on OS X 04:51
tetragon xlc supports all that
Infinoid ok. well, if we want to support xlc builds in parrot at some point in the future, these #ifdefs might need to be extended

tetragon I'm just not sure about __APPLE_CC__ or how commonly used xlc is 04:51

Infinoid unfortunately, if class_init() isn't being called, the reason why is a bit beyond me. 05:12
more later. goodnight
tetragon All this line number switching is making gdb a bit... interesting... 05:13
Infinoid just imagine, we're going to be doing exactly the same thing, once we fix up the .pbc file format a little more :)
you'll not only have line numbers from multiple files, you'll have them from multiple languages! 05:14
tetragon Yay, finally reached the point of interest 05:15
And my_environ ended up as "$2 = (char **) 0x7004" 05:16
Infinoid what do you get when you call _NSGetEnviron() directly? 05:17
and what do you get when you print *((char***)0x7004) ?
(I don't know if its returning the value of the environ pointer, or the address of it.) 05:18
(it looks suspiciously like the address.)
tetragon Same value
And the manpage does specify that it is the address of environ 05:19
Infinoid ok, so if you put a * before the call to _NSGetEnviron(), it might work
...but this doesn't explain why it fails on linux.

Coke Infinoid: env was working on my osx platform. did you break it? =-)
tetragon They needed to by pointed at libparrot
Coke (or did I miss an intermediate patch that changed something.)
tetragon I did a run that threw errors on undefined symbols instead of looking them up dynamically 12:35
(at runtime)
environ is not defined when linking shared libraries 12:36
Infinoid out of curiosity, does that mean tests failed before?
tetragon No
I think what was happening then is that it would look _environ up dynamically at runtime 12:37
(It being dyld)
And it would be found
Infinoid I vaguely remember that this is leading up to removing some other, bigger breakage, but I can't remember the details 12:39
tetragon If parrot weren't linked against libparrot (and libparrot was only found through dynamic lookup) I think failure would have been more likely 12:40
Infinoid fortunately, that isn't very likely :) 12:45
tetragon I think I'll do another -undefined=error (the default) build tonight, this time without removing all references to -fvisibility=hidden
Infinoid ok 12:46
I don't understand what needs to be done to the opengl callbacks, so some more details, or a patch, would help there 12:47
tetragon I got it to go with editing a single line in Makefile

cotto_work nuts
it'd be nice if there were a way to steal/modify the grammar from the reference implementation without messing up licensing issues 19:44
